Certain statements made or incorporated by reference in this Report which are not statements of historical fact, including those under “Management's Discussion and Analysis of Financial Condition and Results of Operations,” and elsewhere in this Report, constitute forward-looking statements within the meaning of, and subject to the protections of, Section 27A of the Securities Act and Section 21E of the Exchange Act. Forward-looking statements include statements with respect to Synovus' beliefs, plans, objectives, goals, targets, expectations, anticipations, assumptions, estimates, intentions and future performance and involve known and unknown risks, many of which are beyond Synovus' control and which may cause Synovus' actual results, performance or achievements or the commercial banking industry or economy generally, to be materially different from future results, performance or achievements expressed or implied by such forward-looking statements.

All statements other than statements of historical fact are forward-looking statements. You can identify these forward-looking statements through Synovus' use of words such as “believes,” “anticipates,” “expects,” “may,” “will,” “assumes,” “predicts,” “could,” “should,” “would,” “intends,” “targets,” “estimates,” “projects,” “plans,” “potential” and other similar words and expressions of the future or otherwise regarding the outlook for Synovus' future business and financial performance and/or the performance of the commercial banking industry and economy in general. Forward-looking statements are based on the current beliefs and expectations of Synovus' management and are subject to significant risks and uncertainties. Actual results may differ materially from those contemplated by such forward-looking statements. A number of factors could cause actual results to differ materially from those contemplated by the forward-looking statements in this document. Many of these factors are beyond Synovus' ability to control or predict. These factors include, but are not limited to:

(1) the risk that competition in the financial services industry may adversely affect our future earnings and growth;

(2) the risk that we may not realize the expected benefits from our efficiency and growth initiatives, which will negatively affect our future profitability;

(3) the risk that our enterprise risk management framework may not identify or address risks adequately, which may result in unexpected losses;

(4) the risk that our allowance for loan losses may prove to be inadequate or may be negatively affected by credit risk exposures;

(5) the risk that any future economic downturn could have a material adverse effect on our capital, financial condition, results of operations and future growth;

(6) changes in the interest rate environment, including changes to the fed funds rate, and competition in our primary market area may result in increased funding costs or reduced earning assets yields, thus reducing margins and net interest income;

(7) the risk that we may be required to make substantial expenditures to keep pace with the rapid technological changes in the financial services market;

(8) risks related to a failure in or breach of our operational or security systems of our infrastructure, or those of our third-party vendors and other service providers, including as a result of cyber-attacks, which could disrupt our businesses, result in the disclosure or misuse of confidential or proprietary information, damage our reputation, increase our costs or cause losses;

(9) risks related to our reliance on third parties to provide key components of our business infrastructure, including the costs of services and products provided to us by third parties, and risks related to disruptions in service or financial difficulties of a third-party vendor;

(10) our ability to attract and retain key employees;

(11) the risk that we could realize losses if we determine to sell non-performing assets and the proceeds we receive are lower than the carrying value of such assets;

(12) the risk that we may not be able to identify suitable acquisition targets as part of our growth strategy and even if we are able to identify suitable acquisition targets, we may not be able to complete such acquisitions or successfully integrate bank or nonbank acquisitions into our existing operations;

(13) the impact of the recent and proposed changes in governmental policy, laws and regulations, including proposed and recently enacted changes in the regulation of banks and financial institutions, or the interpretation or application thereof, including restrictions, increased capital requirements, limitations and/or penalties arising from banking, securities and insurance laws, enhanced regulations and examinations and restrictions on compensation;

(14) the impact on our financial results, reputation, and business if we are unable to comply with all applicable federal and state regulations or other supervisory actions or directives and any necessary capital initiatives;

(15) the risks that if economic conditions worsen or regulatory capital rules are modified, or the results of mandated “stress testing” do not satisfy certain criteria, we may be required to undertake initiatives to improve our capital position;

(16) changes in the cost and availability of funding due to changes in the deposit market and credit market, or the way in which

1

we are perceived in such markets, including a downgrade in our credit ratings;

(17) restrictions or limitations on access to funds from historical and alternative sources of liquidity could adversely affect our overall liquidity, which could restrict our ability to make payments on our obligations and our ability to support asset growth and sustain our operations and the operations of Synovus Bank;

(18) the risk that we may be unable to pay dividends on our common stock or Series C Preferred Stock or obtain any applicable regulatory approval to take certain capital actions, including any increases in dividends on our common stock, any repurchases of common stock or any other issuance or redemption of any other regulatory capital instruments;

(19) our ability to receive dividends from our subsidiaries could affect our liquidity, including our ability to pay dividends or take other capital actions;

(20) the risk that further downgrades of U.S. government securities by one or more of the credit ratings agencies could have a material effect on our operations, earnings, and financial condition;

(21) risks related to recent and proposed changes in the mortgage banking industry, including the risk that we may be required to repurchase mortgage loans sold to third parties and the impact of the “ability to pay” and “qualified mortgage” rules on our loan origination process and foreclosure proceedings;

(22) the risk that for our deferred tax assets, we may be required to increase the valuation allowance in future periods, or we may not be able to realize all of the deferred tax assets in the future;

(23) the risk that we could have an “ownership change” under Section 382 of the Code, which could impair our ability to timely and fully utilize our net operating losses and built-in losses that may exist when such “ownership change” occurs;

(24) the costs and effects of litigation, investigations, inquiries or similar matters, or adverse facts and developments related thereto;

(25) risks related to the fluctuation in our stock price;

(26) the effects of any damages to our reputation resulting from developments related to any of the items identified above; and

(27) other factors and other information contained in this Report and in other reports and filings that we make with the SEC under the Exchange Act, including, without limitation, those found in "Part I - Item 1A.- Risk Factors" of this Report.

For a discussion of these and other risks that may cause actual results to differ from expectations, refer to “Part I - Item 1A. Risk Factors” and other information contained in this Report and our other periodic filings, including quarterly reports on Form 10-Q and current reports on Form 8-K, that we file from time to time with the SEC.

2015 Business Highlights

Synovus' 2015 financial results reflected strong performance with double digit growth in net income and balanced loan growth supported by strong core deposits. Our key achievements in 2015 include the following:

• Earnings growth - Net income available to common shareholders for 2015 was $215.8 million, a 16.7% increase from $185.0 million in 2014. Diluted earnings per share was $1.62 for 2015, up 22.0% from 2014.

• Loan growth - Total loans grew by $1.33 billion or 6.3% from a year ago to $22.43 billion, driven by solid, diversified growth across the entire loan portfolio. See "Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Loans" of this Report for further information.

• Deposit growth - Total average deposits increased $1.58 billion, or 7.6%, to $22.55 billion in 2015, from $20.97 billion in 2014. Average core deposits increased $1.60 billion or 8.2% from 2014, driven by an increase in money market and non-interest bearing demand deposits. See “Part II - Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations - Non-GAAP Financial Measures” in this Report for further information.

• Continued broad-based improvement in credit quality - Credit quality continued to improve. Non-performing assets declined 24.9% to $215.4 million at December 31, 2015. Our NPA ratio was 0.96% as of December 31, 2015, down 39 basis points from December 31, 2014. Additionally, the net charge-off ratio declined 26 basis points to 0.13% compared to 0.39% in 2014.

• Continued focus on expense management - Total non-interest expense for 2015 was $717.7 million, a 3.7% decrease compared to 2014. Adjusted non-interest expense was $677.9 million in 2015, an increase of $2.1 million, or 0.3%, from 2014 as we continued to make strategic investments in talent and technology while also increasing productivity and efficiency. See “Part II - Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations - Non-GAAP Financial Measures” in this Report for further information.

• Return of capital to shareholders while maintaining strong capital levels - We completed the $250 million common stock repurchase program announced in the fourth quarter of 2014, and during the third quarter of 2015 authorized a new $300 million share repurchase program to be completed over the next 15 months. Additionally, we announced a 20% increase in our quarterly common stock dividend from $0.10 to $0.12 per share, effective with the dividend paid on January 4, 2016. Capital levels remained strong, including the common equity Tier 1 ratio which ended the year at 10.37%, well above capital adequacy regulatory requirements.

Management believes that these accomplishments provide continued momentum for long-term profitability and growth in 2016 and future periods.

Additional information relating to our business and our subsidiaries, including a detailed description of our operating results and financial condition for 2015, 2014 and 2013, our loan portfolio (by loan type), our credit quality metrics and our deposits is contained below and under "Part II - Item 7.

Major Non-bank Subsidiaries

In addition to our banking operations, we also provide various other financial services to our customers through the following direct and indirect wholly-owned non-bank subsidiaries:

• Synovus Securities, Inc., headquartered in Columbus, Georgia, which specializes in professional portfolio management for fixed-income securities, investment banking, the execution of securities transactions as a broker/dealer, asset management and financial planning services, and the provision of individual investment advice on equity and other securities;

• Synovus Trust Company, N.A., headquartered in Columbus, Georgia, which provides trust services; and

• Synovus Mortgage Corp., headquartered in Birmingham, Alabama, which offers mortgage services.

Business Developments

Synovus has traditionally focused on a strategy that includes expanding and diversifying its franchise in terms of revenues, profitability and asset size while maintaining a community banking, relationship-based approach to banking. This strategy has encompassed both organic growth and acquisitions of complementary banks and financial services businesses.

During 2015, we continued to execute on our realignment of our corporate, commercial, and retail bankers, and investment professionals to more effectively identify and pursue strategic customer relationships in our markets. We believe these changes, begun in 2014, simplified the way we deliver services to our customers and enabled more consistent delivery across our footprint; leveraged our relationship-based banking model to better align the strengths of our bankers with the needs of our customers; and positioned us to realize increased shareholder value.

Lending Activities

Overview

The primary goal of Synovus' lending function is to help clients achieve their financial goals by providing quality loan products that are fair to the client and profitable to Synovus. Management believes that this purpose can best be accomplished by building strong client relationships over time and maintaining a strong presence and position of influence in the communities Synovus serves. Synovus strives to serve all of its customers with the highest levels of courtesy, respect, gratitude and fairness and deliver its services with unparalleled expertise, efficiency, responsiveness and accuracy. This relationship-based approach to banking enables Synovus' bankers to develop a deep knowledge of Synovus' customers and the markets in which they operate. Synovus has processes to ensure consistency of its lending processes across all of its banking divisions, to maintain strong underwriting criteria to evaluate new loans and loan renewals, and to diversify its loan portfolio in terms of type, industry and geographical concentration. Synovus believes that these measures better position Synovus to meet the credit needs of businesses and consumers in the markets it serves while pursuing a balanced strategy of loan profitability, loan growth and loan quality.

Synovus conducts the majority of its lending activities within the framework of its relationship-based approach to banking, built on creating long-term relationships with its customers. The following tables summarize Synovus' loan portfolio by type at December 31, 2015 and 2014.

The following discussion describes the underwriting procedures of Synovus’ lending function and presents the principal types of lending conducted by Synovus. The results of Synovus’ lending activities and the relative risk of Synovus’ loan portfolio are discussed in “Part II – Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of this Report.

Underwriting Approach

Recognizing that its loan portfolio is the primary source of revenue, Synovus' management believes that proper and consistent loan underwriting throughout Synovus' banking divisions is critical to Synovus' long-term financial success. Synovus' underwriting approach is designed to effectively govern the degree of assumed risk and ensure that its credit relationships conform to Synovus' overall risk philosophy. Synovus' underwriting standards address collateral requirements; guarantor requirements (including policies on financial statements, tax returns, and limited guarantees); requirements regarding appraisals and their review; loan approval hierarchy; standard consumer credit scoring underwriting criteria (including credit score thresholds, maximum maturity and amortization, loan-to-value limits, global debt service coverage, and debt to income limits); commercial real estate and C&I underwriting guidelines (including minimum debt service coverage ratio, maximum amortization, minimum equity requirements, maximum loan-to-value ratios); lending limits; and credit approval authorities. Additionally, Synovus utilizes a loan concentration policy to limit and manage its exposure to certain loan concentrations, including commercial real estate. The loan concentration policy provides a more detailed program for portfolio risk management and reporting, including limits on commercial real estate loans as a percentage of risk-based capital (in the aggregate and by loan type), large borrower concentration limits and monitoring, as well as portfolio mix monitoring. Synovus' underwriting process is structured to require oversight that is proportional to the size and complexity of the lending relationship.

Synovus utilizes a tiered credit approval process requiring all loans to be approved by concurring bank officers. Larger loans are approved by more senior bank officers as well as an independent senior credit officer, with the largest loans requiring approval of Synovus Bank's Loan Committee, which is comprised of the Chief Credit Officer, the Chief Community Banking Officer, the Chief Commercial Banking Officer, and other key executives of Synovus Bank. The centralized underwriting policy and philosophy also provides a structured, conservative approach to lending. For instance, loan-to-value limits on certain credits are lower than regulatory requirements, large borrower concentration limits are explicit, and bank division lending limits are lower than before the credit crisis. Furthermore, Synovus has established across all of its banking divisions more stringent underwriting requirements on certain types of commercial real estate lending, including loans for the purpose of financing shopping centers and land.

Commercial and Industrial (C&I) Loan Portfolio

The C&I loan portfolio represents the largest category of Synovus' total loan portfolio. Synovus' C&I loan portfolio is currently concentrated on small to middle market commercial and industrial lending disbursed throughout a diverse group of industries primarily in the Southeast, including health care and social assistance, manufacturing, retail trade, finance and insurance, real estate-related industries, and wholesale trade. The portfolio is relationship focused and, as a result, Synovus' lenders have in-depth knowledge of the borrowers, most of which have guaranty arrangements. C&I loans are originated through Synovus' local market banking divisions and the Corporate Banking Group to commercial customers primarily to finance capital expenditures, including real property, plant and equipment, or as a source of working capital. At December 31, 2015, 40.0% of Synovus' total C&I loans represented loans for the purpose of financing owner-occupied properties. The primary source of repayment on these C&I loans is revenue generated from products or services offered by the borrower's business. The secondary source of repayment on these C&I loans is the real estate securing such loans. In accordance with Synovus' uniform lending policy, each loan undergoes a detailed underwriting process, which incorporates the uniform underwriting approach, procedures and evaluations described above. Approximately 92% of Synovus' C&I loans are secured by business assets including equipment, inventory, real estate, and other types of collateral. Total C&I loans at December 31, 2015 were $10.79 billion, or 48.1%, of the total loan portfolio.

C&I lending is a key component of Synovus' growth and diversification strategy. Synovus continues to invest in additional lending expertise in key strategic markets as well as offer enhanced products and services to its commercial and industrial clients. Complementing this investment in C&I growth, Synovus' management continues to focus on streamlining and enhancing Synovus' existing product lines, especially for traditional retail, small business and professional services customers.

The Corporate Banking Group provides lending solutions to larger corporate clients and includes specialty units such as loan syndications and senior housing. These units partner with Synovus' local bankers to build relationships across the five-state footprint, as well as other selected areas in the southeastern and southwestern United States. To date, loan syndications consist primarily of loans where Synovus is participating in the credit. Senior housing loans are typically extended to borrowers primarily in the assisted living, independent living, or memory care facilities sectors. The Corporate Banking Group also originates direct loans to well-capitalized public companies and larger private companies that operate predominantly in the five-state footprint and other Southeastern states.

Commercial Real Estate Loan Portfolio

Synovus' commercial real estate loans consist of investment property loans, residential construction and development loans, land acquisition loans, and 1-4 family perm/mini-perm loans. As is the case with Synovus' C&I loans, the commercial real estate loans are primarily originated through Synovus Bank's local market banking divisions. Total commercial real estate loans as of December 31, 2015 were $7.38 billion, or 32.8%, of the total loan portfolio.

Investment Property Loans

Synovus' investment property loans are primarily made to finance multi-family properties, hotels, office buildings, shopping centers, warehouses and other commercial development properties. Synovus' investment property portfolio is well diversified by property type, geography (primarily within Synovus' market areas of Georgia, Alabama, Tennessee, South Carolina, and Florida) and tenants. These loans are generally recourse in nature with short-term maturities (3 years or less), allowing for restructuring opportunities which reduces Synovus' overall risk exposure. The investment property loans are primarily secured by the property being financed by the loans; however, they may also be secured by real estate or other assets beyond the property being financed. Investment property loans are subject to the same uniform lending policies and procedures described above, although such loans have historically been underwritten with stressed interest rates and vacancies. All investment property loans of $1 million or more are reviewed semi-annually to more closely monitor the performance of the portfolio. Total investment property loans as of December 31, 2015 were $5.75 billion, or 25.6%, of the total loan portfolio.

1-4 Family Properties Loans

1-4 family properties loans are almost always secured by the underlying property being financed by such loans. These properties are primarily located in the markets served by Synovus. These loans are subject to the same uniform lending policies and procedures described above.At December 31, 2015, these loans totaled $1.11 billion, or 4.9% of the total loan portfolio.

Land Acquisition Loans

Land acquisition loans are almost always secured by the underlying property being financed by such loans. These properties are primarily located in the markets served by Synovus. These loans are generally subject to the same uniform lending policies and procedures described above. Land acquisition loans have a maximum loan-to-value limit which is aligned with regulatory requirements. At December 31, 2015, these loans were $514.0 million, or 2.3% of the total loan portfolio, compared to $586.0 million or 2.8% of the total loan portfolio at December 31, 2014. Synovus is not actively seeking to originate these types of loans.

7

Retail Loan Portfolio

Synovus' retail loan portfolio consists of a wide variety of loan products offered through its banking network, including residential mortgages, home equity lines, credit card loans, and other retail loans. These various types of secured and unsecured retail loans are marketed to qualifying existing clients and to other creditworthy candidates in Synovus' market area. The majority of Synovus' retail loans are consumer mortgages secured by first and second liens on residential real estate primarily located in the markets served by Synovus in Georgia, Florida, South Carolina, Alabama, and Tennessee. Total retail loans as of December 31, 2015 were $4.29 billion, or 19.1%, of the total loan portfolio.

In accordance with Synovus' lending policy, each loan undergoes a detailed underwriting process which incorporates uniform underwriting standards and oversight that is proportional to the size and complexity of the lending relationship. Retail loans are subject to the same uniform lending policies referenced above and consist primarily of loans with strong borrower credit scores (weighted average FICO scores within the retail residential real estate portfolio were 769 and 766 (HELOCs), respectively, and 759 and 757 (Consumer Mortgages), respectively, at December 31, 2015 and 2014), conservative debt-to-income ratios (average HELOCs debt-to-income ratio of 31.7% and 30.8%, respectively, at December 31, 2015 and 2014), utilization rates (total amount outstanding as a percentage of total available lines) of 60.2% and 61.3% at December 31, 2015 and 2014, respectively, and loan-to-value ratios based upon prudent guidelines to ensure consistency with Synovus' overall risk philosophy. At December 31, 2015 and 2014, 34% and 33%, respectively, of our home equity lines balances were secured by a first lien while 66% and 67%, respectively, were secured by a second lien. Apart from credit card loans and unsecured loans, Synovus does not originate loans with LTV ratios greater than 100% at origination except for infrequent situations provided that certain underwriting requirements are met. Additionally, at origination, loan maturities are determined based on the borrower's ability to repay (cash flow or earning power of the borrower that represents the primary source of repayment) and the collateralization of the loan, including the economic life of the asset being pledged. Collateral securing these loans provides a secondary source of repayment in that the collateral may be liquidated. Synovus determines the need for collateral on a case-by-case basis. Factors considered include the purpose of the loan, current and prospective credit-worthiness of the customer, terms of the loan, and economic conditions.

Mortgage Banking

Synovus originated $1.27 billion in residential mortgage loans in 2015. Synovus offers various types of fixed-rate and adjustable-rate loans for the purpose of purchasing, refinancing or constructing residential properties. The majority of the originated loans are conforming mortgage loans for owner-occupied properties. Conforming loans are loans that are underwritten in accordance with the underwriting standards set forth by government sponsored entities such as the Federal National Mortgage Association and the Federal Home Loan Mortgage Corporation. These loans are generally collateralized by 1-4 family residential real estate properties and are made to borrowers in good credit standing.

The majority of mortgage loans originated by Synovus are sold to third-party purchasers on a servicing released basis, without recourse, or continuing involvement. Each purchaser of our mortgage loans has specific guidelines and criteria for sellers of loans, and the risk of credit loss with regard to the principal amount of the loans sold is generally transferred to the purchasers upon sale. While the loans are sold without recourse, the purchase agreements require Synovus to make certain representations and warranties regarding the existence and sufficiency of file documentation and the absence of fraud by borrowers or other third parties such as appraisers in connection with obtaining the loan. If it is determined that the loans sold were in breach of these representations or warranties, Synovus has obligations to either repurchase the loan for the unpaid principal balance and related investor fees or make the purchaser whole for the economic benefits of the loan. To date, Synovus has experienced minimal repurchase activity in its consumer mortgage lending operations. Additionally, foreclosure activity in the home equity and consumer mortgage loan portfolios has been low.

See “Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Mortgage Banking” and "Part I - Item 1A. Risk Factors - We may be required to repurchase mortgage loans or indemnify mortgage loan purchasers as a result of breaches of representations and warranties, borrower fraud, or certain borrower defaults, which could harm our liquidity, results of operations and financial condition." of this Report for a more detailed discussion of Synovus' obligations with respect to the mortgage loans it sells to third-party purchasers and Synovus' mortgage loan foreclosure practices and risks related to our mortgage loan operations.

Credit Quality

Synovus continuously monitors credit quality and maintains an allowance for loan losses that management believes is sufficient to absorb probable and estimable losses inherent in the loan portfolio. For a more detailed discussion of Synovus' credit quality, see “Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Credit Quality” of this Report for further information.

Monitoring of Collateral

Synovus' loan portfolio and the collateral securing such loans is predominantly located in a five state market consisting of Georgia, Florida, South Carolina, Alabama, and Tennessee. C&I loans represent 48.1% of the total loan portfolio at December 31,

8

2015. These loans are predominantly secured by owner-occupied and other real estate. Other types of collateral securing these loans consist primarily of marketable equipment, marketable inventory, accounts receivable, equity and debt securities, and time deposits. Total commercial real estate loans represent 32.8% of the total loan portfolio at December 31, 2015. These loans are primarily secured by commercial real estate, including 1-4 family properties, land, and investment properties. The collateral generally consists of the property being financed by the loans; however, collateral may also include real estate or other assets beyond the property being financed. Retail loans at December 31, 2015 totaled $4.29 billion, or 19.1%, of the total loan portfolio. Of this amount, $3.63 billion consists of consumer mortgages secured by first and second liens on residential real estate. Credit card loans represent $240.9 million of this amount, and these loans are generally unsecured. Other retail loans represent $423.3 million of this amount, and they are primarily secured by collateral consisting of marketable securities, automobiles, time deposits, and cash surrender value of life insurance.

Synovus follows a risk-based approach as it relates to the credit monitoring processes for its loan portfolio. Synovus updates the fair value of the real estate collateral securing collateral-dependent impaired loans each calendar quarter, with appraisals usually received on a periodic basis from an independent, unaffiliated certified or licensed appraiser. Management also considers other factors or recent developments, such as selling costs and anticipated sales values considering management's plans for disposition, which could result in adjustments to the collateral value estimates indicated in the appraisals. Synovus updates the value of collateral that is in the form of accounts receivable, inventory, equipment, and cash surrender value of life insurance policies at least annually and the value of collateral that is in the form of marketable securities and brokerage accounts at least quarterly.

It is the Company's policy to obtain, on a periodic basis, an updated appraisal from an independent, unaffiliated certified or licensed appraiser for loan relationships of $1 million and over when at least one of the loans in the relationship is on non-accrual status. For relationships under $1 million, while independent appraisals are not mandated by the Company's policies, management will obtain such appraisals when considered prudent. For credits that are not on impaired status, Synovus generally obtains an unaffiliated third-party appraisal of the value of the real estate collateral prior to each loan renewal. Additionally, if conditions warrant (e.g., loans that are not considered impaired but exhibit a higher or potentially higher risk), Synovus engages an unaffiliated appraiser to reappraise the value of the collateral on a more frequent basis. Examples of circumstances that could warrant a new appraisal on an existing performing credit include instances in which local market conditions where the real estate collateral is located have deteriorated, the collateral has experienced damage (e.g., fire, wind damage, etc.), the lease or sell-out of the collateral has not met the original projections, and the net operating income of the collateral has declined. In circumstances where the collateral is no longer considered sufficient, Synovus seeks to obtain additional collateral. Examples of adjustments made quarterly to appraised values include broker's commission, unpaid real estate taxes, attorney's fees, other estimated costs to dispose of the property, known damage to the property, known declines in the net operating income of the property or rent rolls, as well as third-party market data.

Loan Guarantees

In addition to collateral, Synovus generally requires a guarantee from all principals on all commercial real estate and commercial and industrial lending relationships. Specifically, Synovus generally obtains unlimited guarantees from any entity (e.g., individual, corporation, or partnership) that owns or controls 50 percent or more of the borrowing entity. Limited guarantees on a pro-rata basis are generally required for all 20 percent or more owners.

Synovus evaluates the financial ability of a guarantor through an evaluation of the guarantor’s current financial statements, income tax returns for the two most recent years, as well as financial information regarding a guarantor’s business or related interests. In addition, to validate the support that a guarantor provides relating to a commercial real estate loan, Synovus analyzes substantial assets owned by the guarantor to ensure that the guarantor has the necessary ownership interest and control over these assets to convert to cash and the global cash flow of the guarantor. With certain limited exceptions, Synovus seeks performance under guarantees in the event of a borrower’s default.

Unsecured Loans

At December 31, 2015, Synovus had unsecured loans totaling $1.15 billion, which represents approximately 5% of total loans. This segment of our portfolio includes $240.9 million in credit card loans and approximately $893 million in commercial loans to borrowers that are primarily in the manufacturing, insurance, financial services, utilities, and religious organization sectors.

Provision for Loan Losses and Allowance for Loan Losses

Despite credit standards, effective operation of internal controls, and a continuous loan review process, the inherent risk in the lending process results in periodic charge-offs. The provision for loan losses is the charge to operating earnings necessary to maintain an adequate allowance for loan losses. Through the provision for loan losses, Synovus maintains an allowance for losses on loans that management believes will absorb probable losses inherent within the loan portfolio. However, future additions to the allowance may be necessary based on changes in economic conditions, as well as changes in assumptions regarding a borrower's ability to pay and/or collateral values. In addition, various regulatory agencies, as an integral part of their examination procedures,

9

periodically review Synovus Bank's allowance for loan losses. Based on their judgments about information available to them at the time of their examination, such agencies may require Synovus Bank to recognize additions to its allowance for loan losses.

The allowance for loan losses is a significant accounting estimate that is determined through periodic and systematic detailed reviews of the company's loan portfolio. The allowance for loan losses is determined based on an analysis which assesses the inherent risk for probable losses within the loan portfolio. Significant judgments and estimates are necessary in the determination of the allowance for loan losses. Significant judgments include, among others, loan risk ratings and classifications, the determination and measurement of impaired loans, the timing of loan charge-offs, the probability of loan defaults, the net loss exposure in the event of loan defaults, the loss emergence period, qualitative loss factors, management's plans, if any, for disposition of certain loans as well as other qualitative considerations.

See “Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Credit Quality” of this Report for further information.

Non-performing Assets and Past Due Loans

Non-performing assets consist of loans classified as non-accrual, impaired loans held for sale and real estate acquired through foreclosure. Synovus' management continuously monitors non-performing and past due loans to prevent further deterioration regarding the condition of these loans.

See “Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Credit Quality” of this Report for further information.

Investment Activities

Our investment securities portfolio consists principally of debt securities classified as available for sale. Investment securities available for sale provide Synovus with a source of liquidity and a relatively stable source of income. The investment securities portfolio also provides management with a tool to balance the interest rate risk of its loan and deposit portfolios.

Our investment strategy focuses on the use of the investment securities portfolio to generate interest income and to assist in the management of interest rate risk. Synovus also utilizes a significant portion of its investment portfolio to secure certain deposits and other liabilities requiring collateralization. At December 31, 2015, $2.43 billion of these investment securities were pledged to secure certain deposits and securities sold under repurchase agreements as required by law and contractual agreements. The investment securities portfolio consists primarily of mortgage-backed securities issued by U.S. government agencies and U.S. GSEs, both of which have a high degree of liquidity and limited credit risk. A mortgage-backed security depends on the underlying pool of mortgage loans to provide a cash flow pass-through of principal and interest. At December 31, 2015, all of the collateralized mortgage obligations and mortgage-backed pass-through securities held by Synovus were issued or backed by federal agencies or GSEs.

Funding Activities

Liquidity represents the extent to which Synovus has readily available sources of funding to meet the needs of depositors, borrowers, and creditors, to support asset growth, and to otherwise sustain operations of Synovus and its subsidiary, at a reasonable cost, on a timely basis, and without adverse consequences. Core deposits represent the largest source of funds for lending and investing activities. Scheduled payments, as well as prepayments, from our loan and investment portfolios also provide a source of funds. Additional funding sources which provide liquidity include FHLB advances, brokered deposits and other short-term borrowed funds, as well as equity and debt issued through the capital markets. Following is a brief description of the various sources of funds used by Synovus. For further discussion relating to Synovus' funding sources, see “Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Deposits,” “Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity” and "Part II - Item 8. Financial Statements and Supplementary Data - Note 10 - Long-term Debt and Short-term Borrowings" of this Report.

10

Deposits

Deposits provide the most significant funding source for Synovus' interest earning assets and remain a strength of Synovus' business. Deposits are attracted principally from clients within Synovus' retail branch network through the offering of a broad array of deposit products to individuals and businesses, including non-interest bearing demand deposit accounts, interest-bearing demand deposit accounts, savings accounts, money market deposit accounts, and time deposit accounts. Synovus also utilizes brokered deposits as a funding source in addition to deposits attracted through its retail branch network. Terms vary among deposit products with respect to commitment periods, minimum balances, and applicable fees. Interest paid on deposits represents the largest component of Synovus' interest expense. Interest rates offered on interest-bearing deposits are determined based on a number of factors, including, but not limited to, (1) interest rates offered in local markets by competitors, (2) current and expected economic conditions, (3) anticipated future interest rates, (4) the expected amount and timing of funding needs, and (5) the availability and cost of alternative funding sources. Client deposits are attractive sources of funding because of their stability and relative cost. Deposits are regarded as an important part of the overall client relationship and provide opportunities to cross-sell other Synovus services.

See “Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Deposits” of this Report for further information.

Borrowed Funds and Non-Deposit Liquidity

Synovus' ability to borrow funds from non-deposit sources provides additional flexibility in meeting the liquidity needs of Synovus. Synovus generates non-deposit liquidity through scheduled payments and prepayments of loans and investment securities and access to sources of funds other than deposits. Synovus Bank has the capacity to access funding through its membership in the FHLB. At December 31, 2015, Synovus Bank had access to incremental funding, subject to available collateral and FHLB credit policies, through utilization of FHLB advances.

In addition to bank level liquidity management, Synovus must manage liquidity at the Parent Company level for various operating needs including potential capital infusions into subsidiaries, the servicing of debt, the payment of dividends on our common stock and preferred stock, share repurchases and payment of general corporate expenses. The primary source of liquidity for Synovus consists of dividends from Synovus Bank, which is governed by certain rules and regulations of the GA DBF and the FDIC.

During 2014, Synovus Bank made upstream cash distributions to the Parent Company totaling $182.0 million including cash dividends of $90.6 million. During 2015, Synovus Bank made upstream cash distributions to the Parent Company totaling $225.0 million including cash dividends of $199.9 million. On February 12, 2016, Synovus Bank paid an upstream cash dividend of $100.0 million to the Parent Company. Synovus' ability to receive dividends from Synovus Bank in future periods will depend on a number of factors, including, without limitation, Synovus Bank's future profits, asset quality, liquidity and overall condition. In addition, GA DBF rules and related statutes contain limitations on payments of dividends by Synovus Bank without the approval of the GA DBF. See “Part I - Item 1A. Risk Factors - Changes in the cost and availability of funding due to changes in the deposit market and credit market, or the way in which we are perceived in such markets, may adversely affect our capital resources, liquidity and financial results.”

Synovus presently believes that the sources of liquidity discussed above, including existing liquid funds on hand, are sufficient to meet its anticipated funding needs. However, if economic conditions were to significantly deteriorate, regulatory capital requirements for Synovus or Synovus Bank increase as the result of regulatory directives or otherwise, or Synovus believes it is prudent to enhance current liquidity levels, then Synovus may seek additional liquidity from external sources. See "Part I – Item 1A. Risk Factors - Changes in the cost and availability of funding due to changes in the deposit market and credit market, or the way in which we are perceived in such markets, may adversely affect our capital resources, liquidity and financial results."

Enterprise Risk Management

As a financial services organization, Synovus accepts a certain degree of risk with each business decision it makes. Risk management does not eliminate risk, but seeks to achieve an appropriate balance between risk and return, which is critical to optimizing shareholder value. Understanding our risks and managing them appropriately can enhance our ability to make better decisions, deliver on objectives, and improve performance. A risk management framework has been established within Synovus, which begins with the Board of Directors, working primarily with the Risk Committee of the Board. The Risk Committee fulfills the overarching oversight role for the risk management process, including approving risk tolerance levels and risk policies and limits, monitoring key and emerging risks, and reviewing risk assessments. In addition, oversight of certain risk is allocated to all other committees of the Board who meet regularly and report to the Board.

The Chief Risk Officer reports to the Chief Executive Officer and provides overall vision, direction and leadership regarding our enterprise risk management framework. The risk management framework includes an Executive Risk Committee, chaired by the Chief Risk Officer, that consists of all Synovus' corporate executive officers and the Senior Director of Enterprise Risk. The committee meets regularly to monitor Synovus' key and emerging risks and ensures that these risks are effectively managed, assesses capital relative to the Company's risk appetite, and oversees new and modified products and services. Senior management risk committees oversee the various risk types within the Company as shown below and provide minutes of activities and decisions to the Board of Directors. These committees are responsible for ensuring effective risk measurement and management in their respective areas of authority. The Chief Risk Officer is an active member of each of these management risk committees.

• ALCO -Interest Rate/Market Risk and Liquidity Risk

• Credit Risk Committee - Credit Risk

• Regulatory Compliance Risk Committee - Compliance Risk

• Operational Risk Committee - Operational Risk

• Executive Risk Committee - Reputational Risk, Litigation Risk, and Strategic Risk

Management believes that Synovus' primary risk exposures are operational, regulatory compliance, credit, liquidity, and strategic risk. Operational risk arises from the potential that inadequate information systems, operational problems, inadequate or failed internal controls, human error, fraud, security breaches such as cyber-attacks or external events will result in unexpected losses. Compliance risk arises from nonconformance with laws, rules, and regulations that apply to the financial services industry and exposes the Company to monetary penalties, enforcement actions, or other sanctions. Credit risk is risk of loss arising from our borrowers' or counterparties' inability to meet the financial terms of any contract with the Company, or other failure to perform as agreed. Liquidity risk arises from an inability of the Company to meet current or future obligations when they come due without incurring unacceptable losses. Strategic risk arises from threats to long-term growth and strategic direction such as the ability to meet competitive challenges, attract and retain customers, prevent or mitigate cyber security attacks, keep pace with technological changes, and develop new products and services.

ALCO

ALCO monitors Synovus' economic, competitive, and regulatory environment and is responsible for measuring, monitoring, and reporting on liquidity and funding risk, interest rate risk, and market risk and has the authority to create policies relative to these risks. ALCO, operating under liquidity and funding policies approved by the Board of Directors, actively analyzes contractual and anticipated cash flows in order to properly manage Synovus' liquidity position. Operating under interest rate risk policies approved by the Board of Directors, ALCO analyzes the interest rate sensitivity of Synovus and develops and implements strategies to improve balance sheet structure and interest rate risk positioning. See “Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity” and “Item 7A. Qualitative and Quantitative Disclosures about Market Risk” in this Report for further information.

Credit Risk

The Company has established a credit risk management process with policies, controls and regular Board and management oversight. Credit risk management is guided by centralized credit policies that provide for a consistent and prudent approach to underwriting and approvals of credits. The Credit Risk Committee, chaired by the Chief Credit Officer, monitors credit management reports, establishes lending policies, limits, and guidance to better manage the loan function, and provides strategies to manage the level of credit risk in the loan portfolio. The Credit Risk Committee oversees risk grade accuracy, credit servicing requirements, and loan concentration levels and manages risk in the execution of loan growth strategies.

The Regional Credit function reports to the Chief Credit Officer, providing independence from the line of business. Regional Credit manages credit activities within each region, underwriting borrowing relationships over certain dollar thresholds, managing small business accounts, jointly approving loans for amounts greater than the banking division's lending authority, and ensuring that loan administration processes for each banking division are sound and appropriate.

12

Synovus maintains a centralized Retail Lending Center, reporting to the Chief Retail Banking Officer where consumer loans are centrally processed, scored, and analyzed. This structure enhances the control environment, drives efficiencies, and provides a more consistent overall customer experience.

Synovus has established the ALL Oversight Council to review and approve the adequacy of the allowance and ALL methodology. The ALL Oversight Council includes the Chief Risk Officer, Chief Credit Officer, Chief Financial Officer, Chief Accounting Officer, the Senior Director of Enterprise Risk Management, and the Senior Director of Loan Review. The Council meets at least on a quarterly basis and considers enhancements and refinements to the ALL process and models in light of new and other relevant information. The allowance adequacy and the ALL methodology are reviewed by the Audit Committee of the Board of Directors on at least a quarterly basis. The Model Risk Management department reviews the ALL models on an annual basis and prior to implementation of model changes.

Regulatory Compliance Risk

Compliance laws, rules and standards generally cover matters such as observing proper standards of market conduct, managing conflicts of interest, treating customers fairly, and ensuring the suitability of customer advice. They also include basic prudential banking requirements and specific areas such as the prevention of money laundering and terrorist financing.

The Regulatory Compliance Risk Committee was formed to assist the Board and management in overseeing the management of overall compliance risk, developing and implementing policy, and ensuring that compliance issues are resolved effectively and expeditiously. The Committee is made up of senior management from the business lines, risk management, legal, human resources, and compliance functions and specifically provides oversight for the Corporate Compliance Policy and Programs, including UDAAP, Fair Lending, and BSA/AML Policy and Programs and compliance examination exceptions throughout the Company. Written policies contain the principles to be followed by management and staff of the banking divisions, subsidiaries and business lines throughout the Company and explain and direct the processes by which risks are identified and managed. The individual policies guide the Company's compliance functions and provide for monitoring, training, and risk assessments.

Operational Risk

Synovus aims to minimize and mitigate unexpected loss through a proactive and structured approach to operational risk management. The Operational Risk Committee is responsible for providing oversight of the operational risk function to ensure there are effective processes to assess, monitor and mitigate operational risk. Additionally, the Operational Risk Committee is the approval vehicle for the ORM Framework. Specific responsibilities include (1) providing a forum for addressing operational issues that require coordination and/or cooperation of multiple operational groups; (2) identifying and prioritizing operational risk initiatives; (3) reviewing significant operational risk exposures and their conformance to Synovus' stated operational risk objectives; (4) assembling ad hoc committees to address key areas of operational risk identified by the committee and (5) annually reviewing the risk metrics for ongoing pertinence to the risk management framework.

Business units and support functions are accountable for ensuring that the Operational Risk Management Policy is properly communicated and understood within their respective organizational units. Business units are also responsible for identifying and reporting operational risk trends that require resolution, participating in risk assessments, responding to changes in risk metrics and implementing corrective actions and new risk solutions (policies, technology, process change, personnel).

ORM has developed an array of program tools to assist business units in effectively managing operational risk. The program tools seek to ensure standardized implementation of the ORM Framework across the enterprise. ORM Program tools include Risk Control Self-Assessment, issue tracking, loss data management and incident response.

Executive Risk

The Executive Risk Committee is charged with identifying key strategic risks which might threaten the strategic direction and/or long-term viability of Synovus, bringing those risks to the attention of the appropriate Synovus decision-making body, and ensuring Synovus puts in place activities designed to address those risks. This committee consists of all members of executive management, who look beyond their functional areas of responsibility and take a holistic view of the organization and the environment in which it operates.

Competition

The financial services industry is highly competitive and could become more competitive as a result of recent and ongoing legislative, regulatory and technological changes, and continued consolidation and economic turmoil within the financial services industry. The ability of nonbanking financial institutions to provide services previously limited to commercial banks also has intensified competition. Our bank subsidiary and wholly-owned non-bank subsidiaries compete actively with national and state banks, savings and loan associations and credit unions and other nonbank financial institutions, including securities brokers and dealers, investment advisory firms, mortgage companies, insurance companies, trust companies, finance companies, leasing companies, mortgage companies and certain governmental agencies, all of which actively engage in marketing various types of

13

loans, deposit accounts and other financial services. These competitors have been successful in developing products that are in direct competition with or are alternatives to the banking services offered by traditional banking institutions. Our ability to deliver strong financial performance will depend in part on our ability to expand the scope of, and effectively deliver, products and services, which will allow us to meet the changing needs of our customers. However, we often compete with much larger national and regional banks that have more resources than we do to deliver new products and services and introduce new technology to enhance the customer experience. See "Part I - Item IA. Risk Factors -"Competition in the financial services industry may adversely affect our future earnings and growth."

As of December 31, 2015, we were the second largest bank holding company headquartered in Georgia based on assets. Customers for financial services are generally influenced by convenience, quality of service, personal contacts, price of services and availability of products. Although our market share varies in different markets, we hold top five market share in the majority of our markets where we have a presence based on FDIC-insured institutions as of June 30, 2015, and we believe that our community-focused relationship banking approach enables us to compete effectively with other banks and thrifts in the markets we serve.

Employees

As of December 31, 2015, Synovus had 4,452 employees compared to 4,511 employees at December 31, 2014.

Supervision, Regulation and Other Factors

Like all bank holding companies and financial holding companies, we are regulated extensively under federal and state law. In addition, Synovus Bank and certain of our non-bank subsidiaries are subject to regulation under federal and state law. The following discussion sets forth some of the elements of the bank regulatory framework applicable to us and certain of our subsidiaries. The regulatory framework is intended primarily for the protection of depositors and the DIF and not for the protection of security holders and creditors. To the extent that the following information describes statutory and regulatory provisions, it is qualified in its entirety by reference to the particular statutory and regulatory provisions.

General

Bank holding companies and financial holding companies are subject to supervision and regulation by the Federal Reserve Board under the Bank Holding Company Act of 1956, as amended. In addition, the GA DBF, regulates holding companies that own Georgia-chartered banks under the bank holding company laws of the State of Georgia. Synovus Bank, which is not a member of the Federal Reserve System, is subject to supervision and regulation by the FDIC, and by its state banking regulator, the GA DBF. Numerous other federal and state laws, as well as regulations promulgated by the Federal Reserve Board, the GA DBF, and the FDIC govern almost all aspects of the operations of Synovus Bank. Synovus Trust Company, N.A., a subsidiary of Synovus Bank that provides trust services, is organized as a national trust bank and thus is subject to supervision and regulation by the Office of the Comptroller of the Currency. Various federal and state bodies regulate and supervise our non-bank subsidiaries including our brokerage, investment advisory, insurance agency and processing operations. These include, but are not limited to, the SEC, the Financial Industry Regulatory Authority, federal and state banking regulators and various state regulators of insurance and brokerage activities.

In addition, we are subject to supervision and regulation by the CFPB with regard to our offering and provision of consumer financial products and services. The CFPB was established by the Dodd-Frank Act of 2010, which is discussed in greater detail below. The CFPB has broad authority to regulate the offering and provision of consumer financial products. The CFPB has rulemaking authority for a range of federal consumer financial protection laws (such as the Truth in Lending Act, the Electronic Funds Transfer Act, and the Real Estate Settlement Procedures Act). The CFPB has the authority to supervise and examine depository institutions, like Synovus Bank, with more than $10 billion in assets, together with all affiliates of such a depository institution, like us and our subsidiaries, for compliance with these federal consumer financial protection laws. Finally, the CFPB has broad enforcement authority with regard to compliance with federal consumer financial protection laws.

Permitted Activities

The Bank Holding Company Act limits the activities in which bank holding companies and their subsidiaries may engage. A bank holding company and its subsidiaries are generally permitted to engage in or acquire direct or indirect control of more than 5 percent of the voting shares of any company engaged in those activities that are “closely related to banking” as defined by the Federal Reserve Board.

The Federal Reserve Board has the authority to order a bank holding company or its subsidiaries to terminate any of these activities or to terminate its ownership or control of any subsidiary when it has reasonable cause to believe that the bank holding company's continued ownership, activity or control constitutes a serious risk to the financial safety, soundness or stability of it or any of its bank subsidiaries.

A bank holding company, such as us, may file an election with the Federal Reserve Board to be treated as a financial holding company and engage in an expanded list of financial activities. The election must be accompanied by a certification that the

14

company's insured depository institution subsidiary is “well capitalized” and “well managed.” Additionally, the rating of the bank holding company's subsidiary bank(s) under the Community Reinvestment Act of 1977 must be satisfactory or better. We have made such an election and are treated as a financial holding company. As such, we may engage in activities that are financial in nature or incidental or complementary to financial activities, including insurance underwriting, securities underwriting and dealing, and making merchant banking investments in commercial and financial companies. If either of our depository institution subsidiaries, Synovus Bank or Synovus Trust Company, ceases to be “well capitalized” or “well managed” under applicable regulatory standards, the Federal Reserve Board may, among other things, place limitations on our ability to conduct these broader financial activities or, if the deficiencies persist, require us to divest the banking subsidiary or the businesses engaged in activities permissible only for financial holding companies. In addition, if Synovus Bank receives a rating of less than satisfactory under the Community Reinvestment Act, we would be prohibited from engaging in any additional activities other than those permissible for bank holding companies that are not financial holding companies. If, after becoming a financial holding company and undertaking activities not permissible for a bank holding company, the company fails to continue to meet any of the prerequisites for financial holding company status, including those described above, the company must enter into an agreement with the Federal Reserve Board to comply with all applicable requirements. If the company does not return to compliance within 180 days, the Federal Reserve Board may order the company to divest its subsidiary bank or the company may discontinue or divest investments in companies engaged in, activities permissible only for a financial holding company.

Actions by Federal and State Regulators

Like all bank and financial holding companies, we are regulated extensively under federal and state law. Under federal and state laws and regulations pertaining to the safety and soundness of insured depository institutions, state banking regulators, the Federal Reserve Board, and separately the FDIC as the insurer of bank deposits, have the authority to compel or restrict certain actions on our part if they determine that we have insufficient capital or other resources, or are otherwise operating in a manner that may be deemed to be inconsistent with safe and sound banking practices. Under this authority, our bank regulators can require us or our subsidiaries to enter into informal or formal supervisory agreements, including board resolutions, memoranda of understanding, written agreements and consent or cease and desist orders, pursuant to which we would be required to take identified corrective actions to address cited concerns and to refrain from taking certain actions.

If we become subject to and are unable to comply with the terms of any future regulatory actions or directives, supervisory agreements, or orders, then we could become subject to additional, heightened supervisory actions and orders, possibly including consent orders, prompt corrective action restrictions and/or other regulatory actions, including prohibitions on the payment of dividends on our common stock and preferred stock. If our regulators were to take such additional supervisory actions, then we could, among other things, become subject to significant restrictions on our ability to develop any new business, as well as restrictions on our existing business, and we could be required to raise additional capital, dispose of certain assets and liabilities within a prescribed period of time, or both. The terms of any such supervisory action could have a material negative effect on our business, reputation, operating flexibility, financial condition, and the value of our common stock and preferred stock. See “Part I - Item 1A. Risk Factors - We may become subject to supervisory actions and enhanced regulation that could have a material negative effect on our business, reputation, operating flexibility, financial condition and the value of our common stock and preferred stock.” of this Report.

Change in Control

Subject to certain exceptions, the Bank Holding Company Act and the Change in Bank Control Act, together with regulations promulgated thereunder, require Federal Reserve Board approval prior to any person or company acquiring “control” of a bank or bank holding company. Control is conclusively presumed to exist if an individual or company acquires 25 percent or more of any class of voting securities, and a rebuttable presumption of control exists if a person acquires 10 percent or more, but less than 25 percent, of any class of voting securities and either the company has registered securities under Section 12 of the Exchange Act or no other person owns a greater percentage of that class of voting securities immediately after the transaction. In certain cases, a company may also be presumed to have control under the Bank Holding Company Act if it acquires 5 percent or more of any class of voting securities. Our common stock and preferred stock is registered under Section 12 of the Exchange Act.

On September 22, 2008, the Federal Reserve Board issued a policy statement on non-controlling equity investments in banks and bank holding companies, that permits investors to (1) acquire up to 33 percent of the total equity of a target bank or bank holding company, subject to certain conditions, including (but not limited to) that the investing firm does not acquire 15 percent or more of any class of voting securities and (2) designate at least one director, without triggering the various regulatory requirements associated with control.

Standards for Safety and Soundness

The Federal Deposit Insurance Act requires the federal bank regulatory agencies to prescribe, by regulation or guideline, operational and managerial standards for all insured depository institutions relating to: (1) internal controls, information systems and audit systems; (2) loan documentation; (3) credit underwriting; (4) interest rate risk exposure; and (5) asset quality. The agencies also must prescribe standards for asset quality, earnings, and stock valuation, as well as standards for compensation, fees and benefits, including a prohibition on any compensatory arrangement that would provide any executive officer, employee, director, or principal shareholder of the institution with excessive compensation, fees or benefits and any compensatory arrangement that could lead to material financial loss to an institution. The federal banking agencies have adopted regulations and Interagency Guidelines Prescribing Standards for Safety and Soundness to implement these required standards. These guidelines set forth the safety and soundness standards used to identify and address problems at insured depository institutions before capital becomes impaired. Under the regulations, if a regulator determines that a bank fails to meet any standards prescribed by the guidelines, the regulator may require the bank to submit an acceptable plan to achieve compliance, consistent with deadlines for the submission and review of such safety and soundness compliance plans.

Dividends

Synovus is a legal entity separate and distinct from its subsidiaries. Under the laws of the State of Georgia, we, as a business corporation, may declare and pay dividends in cash or property unless the payment or declaration would be contrary to restrictions contained in our Articles of Incorporation, or unless, after payment of the dividend, we would not be able to pay our debts when they become due in the usual course of our business or our total assets would be less than the sum of our total liabilities. In addition, we are also subject to federal regulatory capital requirements that effectively limit the amount of cash dividends, if any that we may pay.

The Federal Reserve Board may restrict our ability to pay dividends on any class of stock or any other Tier 1 capital instrument if we are not deemed to have a strong capital position. In addition, we may have to reduce or eliminate dividends if:

• our net income available to shareholders for the past four quarters, net of dividends previously paid during that period, is not sufficient to fully fund the dividends;

•our prospective rate of earnings retention is not consistent with our capital needs and overall current and

prospective financial condition; or

•we will not meet, or are in danger of not meeting, the minimum regulatory capital adequacy ratios.

Further, Federal Reserve Board guidance provides that bank holding companies should consult with the Federal Reserve Board before taking any actions that could result in a diminished capital base, including increasing dividends or redeeming or repurchasing common stock or other regulatory capital instruments.

The Federal Reserve Board has indicated that bank holding companies should carefully review their dividend policy and has in some cases discouraged payment unless both asset quality and capital are very strong.

The primary sources of funds for our payment of dividends to our shareholders are cash on hand and dividends from Synovus Bank and our non-bank subsidiaries. Various federal and state statutory provisions and regulations limit the amount of dividends that Synovus Bank and our non-bank subsidiaries may pay. Synovus Bank is a Georgia bank. Under the regulations of the GA DBF, a Georgia bank must have approval of the GA DBF to pay cash dividends if, at the time of such payment:

• the ratio of Tier 1 capital to adjusted total assets is less than 6 percent;

•the aggregate amount of dividends to be declared or anticipated to be declared during the current calendar year exceeds

50 percent of its net after-tax profits before dividends for the previous calendar year; or

•its total classified assets in its most recent regulatory examination exceeded 80 percent of its Tier 1 capital plus its

allowance for loan and lease losses.

In addition, the Georgia Financial Institutions Code contains restrictions on the ability of a Georgia bank to pay dividends other than from retained earnings without the approval of the GA DBF. As a result of the foregoing restrictions, Synovus Bank may be required to seek approval from the GA DBF to pay dividends.

The Federal Deposit Insurance Corporation Improvement Act of 1991, or FDICIA, generally prohibits a depository institution from making any capital distribution, including payment of a dividend, or paying any management fee to its holding company, if the institution would thereafter be undercapitalized. In addition, federal banking regulations applicable to us and our bank subsidiaries require minimum levels of capital that limit the amounts available for payment of dividends. Finally, “stress testing requirements” established by the Dodd-Frank Act, which are described below in “Our Capital Requirements,” may impact the ability of some banks and bank holding companies to pay dividends.

See “Part II - Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Repurchases of Equity Securities - Dividends” and “Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Parent Company” of this Report for further information.

Capital

We are required to comply with the capital adequacy standards established by the Federal Reserve Board and our bank subsidiary must comply with similar capital adequacy standards established by the FDIC. As a financial holding company, we, Synovus Bank, and Synovus Trust Company are required to maintain capital levels required for a well-capitalized institution, as that term is defined in “Prompt Corrective Action for Undercapitalization” below.

Our Capital Requirements

The Federal Reserve Board has issued guidelines pursuant to which it assesses the adequacy of capital in examining and supervising a bank holding company or financial holding company. These guidelines include quantitative measures that assign risk weightings to assets and off-balance sheet items and that define and set minimum regulatory capital requirements. Effective on January 1, 2015, this regulatory capital framework changed in important respects for us as a result of new rules (“Basel III Capital Rules” or “Revised Rules”) implementing the Dodd-Frank Act and a separate, international regulatory capital initiative known as “Basel III.” Among other things, the Basel III Capital Rules raised the minimum thresholds for required capital and revised certain aspects of the definitions and elements of the capital that can be used to satisfy these required minimum thresholds. While the rules became effective on January 1, 2014 for certain large banking organizations, most U.S. banking organizations, including Synovus and Synovus Bank, began compliance on January 1, 2015.

Through December 31, 2014, the applicable capital guidelines required all bank holding companies to maintain Tier 1 Capital of at least 4 percent of risk-weighted assets, Total Capital (the sum of Tier 1 Capital and Tier 2 Capital) of at least 8 percent of risk-weighted assets and Tier 1 Capital of at least 4 percent of adjusted quarterly average assets. Under this framework, Tier 1 Capital consisted principally of shareholders' equity less any amounts of disallowed deferred tax assets, goodwill, other intangible assets, non-financial equity investments, and other items that are required to be deducted by the Federal Reserve Board. Tier 2 Capital consisted principally of perpetual and trust preferred stock that was not eligible to be included as Tier 1 Capital, term subordinated debt, intermediate-term preferred stock and, subject to limitations, general allowances for loan and lease losses.

The Basel III Capital Rules make substantial changes to this framework. Among other things, the Revised Rules (1) introduced a new capital measure called “Common Equity Tier 1” (“CET1”), (2) specified that Tier 1 Capital consist of CET1 and “Additional Tier 1 Capital” instruments meeting certain requirements, (3) defined CET1 narrowly by requiring that most deductions/adjustments to regulatory capital measures be made to CET1 and not to the other components of capital and (4) expanded the scope of the deductions/adjustments from capital that apply to Synovus and other banking organizations. Under the Revised Rules, for most banking organizations, including Synovus, the most common form of “Additional Tier 1 Capital” is non-cumulative perpetual preferred stock, such as our Series C Preferred Stock, and the most common forms of Tier 2 capital are subordinated notes and a portion of the allocation for loan losses, in each case, subject to certain specific requirements set forth in the regulation. Under the Revised Rules, certain hybrid securities, such as trust preferred securities, do not qualify as Tier 1 capital.

Similar to the rules applicable to our results through 2014, under the Revised Rules, assets are adjusted under the risk-based guidelines to take into account different risk characteristics. The Revised Rules changed risk weights for certain assets and off-balance sheet exposures that resulted in higher risk weights for a variety of asset categories, including a 150% risk weight (instead of a 100% risk weight) for certain high volatility commercial real estate acquisition, development and construction loans.

Further, the Revised Rules set forth the following minimum capital ratios, effective January 1, 2015:

• 4.5 percent CET1 to risk-weighted assets.

• 6.0 percent Tier 1 Capital to risk-weighted assets.

• 8.0 percent Total Capital to risk-weighted assets.

• 4.0 percent Tier 1 leverage ratio to average consolidated assets.

As discussed below, the Revised Rules also provide for changes to the Prompt Corrective Action framework to correspond to these new minimum capital thresholds.

The Revised Rules provide for a number of deductions from and adjustments to CET1, which include the requirement that mortgage servicing rights, deferred tax assets arising from temporary differences that could not be realized through net operating loss carrybacks and significant investments in non-consolidated financial entities be deducted from CET1 to the extent that any one such category exceeds 10% of CET1 or all such categories in the aggregate exceed 15% of CET1. Implementation of the deductions and other adjustments to CET1 began on January 1, 2015 and will be phased-in over a three-year period (beginning at 40% on January 1, 2015 and an additional 20% per year thereafter until fully phased-in at January 1, 2018).

17

The Basel III Capital Rules also introduce a minimum “capital conservation buffer” equal to 2.5% of an organization’s total risk-weighted assets, which exists in addition to the required minimum CET1, Tier 1, and Total Capital ratios identified above. The “capital conservation buffer,” which must consist entirely of CET1, is designed to absorb losses during periods of economic stress. The implementation of the capital conservation buffer began on January 1, 2016 at the 0.625% level and will be phased-in over a three-year period (increasing by that amount on each subsequent January 1, until it reaches 2.5% on January 1, 2019). Thus, when the capital conservation buffer is fully phased-in on January 1, 2019, the Revised Rules will require us to maintain: (1) a minimum ratio of CET1 to risk-weighted assets of at least 4.5%, plus the 2.5% capital conservation buffer, effectively resulting in a minimum ratio of CET1 to risk-weighted assets of at least 7%, (2) a minimum ratio of Tier 1 capital to risk-weighted assets of at least 6.0%, plus the capital conservation buffer, effectively resulting in a minimum Tier 1 capital ratio of 8.5%, (3) a minimum ratio of Total capital (that is, Tier 1 plus Tier 2) to risk-weighted assets of at least 8.0%, plus the capital conservation buffer, effectively resulting in a minimum total capital ratio of 10.5% and (4) a minimum leverage ratio of 4%, calculated as the ratio of Tier 1 capital to average assets.

Under capital standards applicable to our 2014 results, the effects of accumulated other comprehensive income items included in shareholders’ equity under U.S. GAAP were excluded for the purposes of determining regulatory capital ratios. Under the Revised Rules, the effects of certain accumulated other comprehensive items are not excluded. However, the Revised Rules permit most banking organizations, including us and Synovus Bank, to make a one-time permanent election to continue to exclude these items. Synovus and Synovus Bank have made the permanent election to exclude accumulated other comprehensive income from regulatory capital by selecting the "opt-out" election on the March 31, 2015 Call Report and FR Y-9C; thus, Synovus and Synovus Bank will retain the same accumulated other comprehensive income treatment as under the regulatory capital rules in effect prior to January 1, 2015.

As of December 31, 2015, based on management’s interpretation of the Revised Rules, Synovus meets all capital adequacy requirements including the capital conservation buffer, under the Basel III Capital Rules on a fully phased-in basis if such requirements were currently effective. See “Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Non-GAAP Financial Measures" in this Report for applicable reconciliation.

Regardless, complying with the Revised Rules will likely affect our operations going forward.

We are also subject to “stress testing” requirements that are designed to require banking organizations to assess the potential impact of different scenarios on their earnings, losses, and capital over a set time period, with consideration given to certain relevant factors, including the organization's condition, risks, exposures, strategies, and activities. Specifically, banking organizations with total consolidated assets of more than $10 billion but less than $50 billion, such as us and Synovus Bank, are required to conduct annual company-run stress tests, report the results to their primary federal regulator and the Federal Reserve Board, and publish a summary of the results. Among other things, these rules establish stress test methodologies, set forth the form of the report that must be submitted, and require publication of a summary of results. Under the rules, stress tests must be conducted using certain scenarios (baseline, adverse and severely adverse), which the Federal Reserve Board and the FDIC will provide each year. In addition, the rules require such organizations to begin publicly disclosing a summary of certain stress test results (i.e., results under the “severely adverse” scenario). On June 19, 2015, we disclosed a summary of our results of the stress testing on our website.

For 2016, due to a change in rules, the stress testing cycle which would have begun on October 1, 2015 instead began on January 1, 2016, using financial data as of December 31, 2015. The scenarios were provided by February 15, 2016, and we are required to conduct and submit the results of the stress tests to our regulators by July 31 and publish a summary of those results between October 15 and October 31, 2016, unless that time period is extended by the regulators. Subsequent years will follow the same schedule.

In addition, the banking agencies have issued guidance on stress testing for banking organizations with more than $10 billion in total consolidated assets, which outlines four “high-level” principles for stress testing practices that should be a part of a banking organization's stress-testing framework. Regulators have stated that they expect banking organizations subject to the guidance to comply with these principles when conducting stress testing in accordance with the Dodd-Frank Act requirements discussed above. The guidance calls for a banking organization’s stress testing framework to (1) include activities and exercises that are tailored to and sufficiently capture the banking organization's exposures, activities and risks; (2) employ multiple conceptually sound stress testing activities and approaches; (3) be forward-looking and flexible; and (4) be clear, actionable, well-supported, and used in the decision-making process.

See "Part I - Item 1A. Risk Factors - We may be required to undertake additional strategic initiatives to improve our capital position due to changes in economic conditions or changes in regulatory capital rules." of this Report.

Prompt Corrective Action for Undercapitalization

FDICIA established a system of prompt corrective action to resolve the problems of undercapitalized insured depository institutions. Under this system, the federal banking regulators are required to rate insured depository institutions on the basis of five capital categories as described below. The federal banking regulators are also required to take mandatory supervisory actions and are authorized to take other discretionary actions, with respect to insured depository institutions in the three undercapitalized categories, the severity of which will depend upon the capital category in which the insured depository institution is assigned. Generally, subject to a narrow exception, FDICIA requires the banking regulator to appoint a receiver or conservator for an insured depository institution that is critically undercapitalized. The federal banking agencies have specified by regulation the relevant capital level for each category. The thresholds for each of these categories were revised pursuant to the Basel III Capital Rules, which are discussed above in “Our Capital Requirements.” These revised categories applied to Synovus Bank beginning on January 1, 2015, and are discussed below. Under the regulations, all insured depository institutions are assigned to one of the following capital categories:

• Well Capitalized - A well-capitalized insured depository institution is one (1) having a total risk-based capital ratio of 10 percent or greater, (2) having a Tier 1 risk-based capital ratio of 8 percent or greater, (3) having a CET1 capital ratio of 6.5 percent or greater, (4) having a leverage capital ratio of 5 percent or greater and (5) that is not subject to any order or written directive to meet and maintain a specific capital level for any capital measure.

• Adequately Capitalized - An adequately-capitalized depository institution is one having (1) a total risk-based capital ratio of 8 percent or more, (2) a Tier 1 capital ratio of 6 percent or more, (3) a CET1 capital ratio of 4.5 percent or more, and (4) a leverage ratio of 4 percent or more.

• Undercapitalized - An undercapitalized depository institution is one having (1) a total capital ratio of less than 8 percent, (2) a Tier 1 capital ratio of less than 6 percent, (3) a CET1 capital ratio of less than 4.5 percent, or (4) a leverage ratio of less than 4 percent.

• Significantly Undercapitalized - A significantly undercapitalized institution is one having (1) a total risk-based capital ratio of less than 6 percent (2) a Tier 1 capital ratio of less than 4 percent, (3) a CET1 ratio of less than 3 percent or (4) a leverage capital ratio of less than 3 percent.

• Critically Undercapitalized - A critically undercapitalized institution is one having a ratio of tangible equity to total assets that is equal to or less than 2 percent.

The prompt corrective action regulations permit the appropriate federal banking regulator to downgrade an institution to the next lower category if the regulator determines after notice and opportunity for hearing or response that the institution (1) is in an unsafe or unsound condition or (2) has received and not corrected a less-than-satisfactory rating for any of the categories of asset quality, management, earnings or liquidity in its most recent examination. Supervisory actions by the appropriate federal banking regulator depend upon an institution's classification within the five categories. Our management believes that our insured bank subsidiary, Synovus Bank, has the requisite capital levels to qualify as a well capitalized institution under the FDICIA regulations. See “Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Capital Resources” and "Part II - Item 8. Financial Statements and Supplementary Data - Note 12 - Regulatory Capital" of this Report for further information.

If an institution fails to remain well-capitalized, it will be subject to a variety of enforcement remedies that increase as the capital condition worsens. For instance, FDICIA generally prohibits an insured depository institution from making any capital

19

distribution, including payment of a dividend, or paying any management fee to its holding company if the depository institution would thereafter be undercapitalized as a result. Undercapitalized depository institutions are subject to restrictions on borrowing from the Federal Reserve System. In addition, undercapitalized depository institutions may not accept brokered deposits absent a waiver from the FDIC, are subject to growth limitations and are required to submit capital restoration plans for regulatory approval. A depository institution's holding company must guarantee any required capital restoration plan, up to an amount equal to the lesser of 5 percent of the depository institution's assets at the time it becomes undercapitalized or the amount of the capital deficiency when the institution fails to comply with the plan. Federal banking agencies may not accept a capital plan without determining, among other things, that the plan is based on realistic assumptions and is likely to succeed in restoring the depository institution's capital. If a depository institution fails to submit an acceptable plan, it is treated as if it is significantly undercapitalized.

Significantly undercapitalized depository institutions may be subject to a number of requirements and restrictions, including orders to sell sufficient voting stock to become adequately capitalized, requirements to reduce total assets and cessation of receipt of deposits from correspondent banks. Critically undercapitalized depository institutions are subject to appointment of a receiver or conservator.

Deposit Insurance and Assessments

Deposits at Synovus Bank are insured by the DIF, as administered by the FDIC, up to the applicable limits established by law. The Dodd-Frank Act amended the statutory regime governing the DIF. Among other things, the Dodd-Frank Act established a minimum designated reserve ratio of 1.35% of estimated insured deposits (which the FDIC has set at 2.0% each year since 2010), required that the fund reserve ratio reach 1.35% by September 30, 2020, and directed the FDIC to amend its regulations to redefine the assessment base used for calculating deposit insurance assessments. Specifically, the Dodd-Frank Act requires the assessment base to be an amount equal to the average consolidated total assets of the insured depository institution during the assessment period, minus the sum of the average tangible equity of the insured depository institution during the assessment period and an amount the FDIC determines is necessary to establish assessments consistent with the risk-based assessment system found in the Federal Deposit Insurance Act. Under proposed rules set forth by the FDIC in October 2015, banks such as Synovus Bank with at least $10 billion in assets would pay a surcharge of 4.5 cents per $100 of their assessment base, after making certain adjustments to enable the reserve ratio to reach 1.35% after approximately two years of payments of the proposed surcharges.

Under the FDIC’s rules, the total base assessment rates vary depending on the DIF reserve ratio. For example, for banks in the best risk category, the total base assessment rates will be between 2.5 and 9 basis points when the DIF reserve ratio is below 1.15%, between 1.5 and 7 basis points when the DIF reserve ratio is between 1.15% and 2.0%, between 1 and 6 basis points when the DIF reserve ratio is between 2.0% and 2.5% and between 0.5 and 5 basis points when the DIF reserve ratio is 2.5% or higher.

In addition, the FDIC collects FICO deposit assessments, which are calculated off of the assessment base described above. FICO assessments are set quarterly, and it was 0.590 (annual) basis points for all four quarters in 2015. Synovus Bank pays the deposit insurance assessment and pays the quarterly FICO assessments.

With respect to brokered deposits, an insured depository institution must be well-capitalized in order to accept, renew or roll over such deposits without FDIC clearance. An adequately capitalized insured depository institution must obtain a waiver from the FDIC in order to accept, renew or roll over brokered deposits. Undercapitalized insured depository institutions generally may not accept, renew or roll over brokered deposits. See “Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Deposits” of this Report for further information.

Dodd-Frank Act; Future Changes to Legal Framework

The Dodd-Frank Act of 2010 brought about a significant overhaul of many aspects of the regulation of the financial services industry, addressing, among other things, systemic risk, capital adequacy, deposit insurance assessments, consumer financial protection, interchange fees, derivatives, lending limits, mortgage lending practices, registration of investment advisors and changes among the bank regulatory agencies. Key provisions of the Dodd-Frank Act that have impacted or are likely to impact the operations of Synovus or Synovus Bank include:

• Creation of the CFPB with with centralized authority, including rulemaking, examination and enforcement authority, for consumer protection in the banking industry.

• New limitations on federal preemption.

• New prohibitions and restrictions on the ability of a banking entity to engage in proprietary trading and have certain interests in, or relationships with, a hedge fund or private equity fund (known as the "Volcker Rule").

• Application of new regulatory capital requirements, including changes to leverage and risk-based capital standards and changes to the components of permissible tiered capital.

• Requirement that the company and its subsidiary banks be well capitalized and well managed in order to engage in activities permitted for financial holding companies.

• Changes to the assessment base for deposit insurance premiums.

20

• Permanently raising the FDIC's standard maximum insurance amount to $250,000.

• Repeal of the prohibition on the payment of interest on demand deposits, therereby permitting depository institutions to pay interest on business transaction and other accounts.

• Restrictions on compensation, including a prohibition on incentive-based compensation arrangements that encourage inappropriate risk by taking covered financial institutions and are deemed to be excessive, or that may lead to material losses.

• Requirement that sponsors of asset-backed securities retain a percentage of the credit risk underlying the securities.

• Requirement that banking regulators remove references to and requirements of reliance upon credit ratings from their regulations and replace them with appropriate alternatives for evaluating creditworthiness.

Some of these and other major changes, could materially impact the profitability of our business, the value of assets we hold or the collateral available for our loans, require changes to business practices or force us to discontinue businesses and expose us to additional costs, taxes, liabilities, enforcement actions and reputational risk. Many of these provisions became effective upon enactment of the Dodd-Frank Act, while others were subject to further study, rule-making, and the discretion of regulatory bodies and have only recently taken effect or will take effect in the coming years.

In light of these significant changes and the discretion afforded to federal regulators, we cannot fully predict the effect that compliance with the Dodd-Frank Act or any implementing regulations will have on Synovus' businesses or its ability to pursue future business opportunities. Additional regulations resulting from the Dodd-Frank Act may materially adversely affect Synovus' business, financial condition or results of operations. See “Part 1 - Item 1A. Risk Factors - Regulation of the financial services industry continues to undergo major changes, and future legislation could increase our cost of doing business or harm our competitive position.” of this Report.

Additional changes to the laws and regulations applicable to us are frequently proposed at both the federal and state levels. The likelihood, timing, and scope of any such change and the impact any such change may have on us are impossible to determine with any certainty.

Volcker Rule

In December 2013, the Federal Reserve Board and other regulators jointly issued final rules implementing requirements of a new Section 13 to the Bank Holding Company Act, commonly referred to as the “Volcker Rule.”

The Volcker Rule generally prohibits Synovus and its subsidiaries from (i) engaging in proprietary trading for its own account, and (ii) acquiring or retaining an ownership interest in or sponsoring a “covered fund,” all subject to certain exceptions. The Volcker Rule also specifies certain limited activities in which Synovus and its subsidiaries may continue to engage, and requires us to implement a compliance program.

The regulators provided for a Volcker Rule conformance date of July 21, 2015. Conformance with the provisions prohibiting certain “covered funds” activities was extended by a Federal Reserve Board order that provided for an extension of the Volcker Rule conformance period for legacy ownership interests and sponsorship of covered funds until July 21, 2016. The Federal Reserve Board has expressed its intention to grant the last available statutory extension for such covered funds activities until July 21, 2017.

The Volcker Rule will further restrict and limit the types of activities in which Synovus and its subsidiaries may engage. Moreover, it will require Synovus and its subsidiaries to adopt complex compliance monitoring and reporting systems in order to ensure compliance with the rule while engaging in activities that Synovus and its subsidiaries currently conduct.

Consumer Protection Regulations

Retail activities of banks are subject to a variety of statutes and regulations designed to protect consumers, which for us and our subsidiaries and affiliates are enforced at the federal level by the CFPB. Interest and other charges collected or contracted for by banks are subject to state usury laws and federal laws concerning interest rates. Loan operations are also subject to federal laws applicable to credit transactions, such as:

• the federal Truth-In-Lending Act and Regulation Z , governing disclosures of credit terms to consumer borrowers;

• the Real Estate Settlement Procedures Act and Regulation X, providing for certain practices and disclosures in residential real estate lending (including disclosures integrated with those required by Regulation Z);

• the Home Mortgage Disclosure Act and Regulation C, requiring financial institutions to provide information to enable the public and public officials to determine whether a financial institution is fulfilling its obligation to help meet the housing needs of the community it serves;

• the Equal Credit Opportunity Act and Regulation B, on the basis of race, color, religion, national origin, sex, marital status, age or other prohibited factors in extending credit;

21

• the Fair Credit Reporting Act and Regulation V, governing the use and provision of information to consumer reporting agencies;

• the Fair Debt Collection Practices Act, governing the manner in which consumer debts may be collected by collection agencies; and

• the guidance of the various federal agencies charged with the responsibility of implementing such federal laws.

Deposit operations also are subject to:

• the Truth in Savings Act and Regulation DD, which requires disclosure of deposit terms to consumers;

• Regulation CC, which relates to the availability of deposit funds to consumers;

• the Right to Financial Privacy Act, which imposes a duty to maintain the confidentiality of consumer financial records and prescribes procedures for complying with administrative subpoenas of financial records; and

• the Electronic Funds Transfer Act and Regulation E, which governs automatic deposits to and withdrawals from deposit accounts and customers' rights and liabilities arising from the use of automated teller machines and other electronic banking services, as well as electronic transfers initiated by consumers in the U.S. to recipients in foreign countries.

The CFPB adopted a rule that implements the ability-to-repay and qualified mortgage provisions of the Dodd-Frank Act (the “ATR/QM rule”), which took effect on January 10, 2014, and has impacted our residential mortgage lending practices, and the residential mortgage market generally. The ATR/QM rule requires lenders to consider, among other things, income, employment status, assets, payment amounts, and credit history before approving a mortgage, and provides a compliance “safe harbor” for lenders that issue certain “qualified mortgages.” The ATR/QM rule defines a “qualified mortgage” to have certain specified characteristics, and generally prohibit loans with negative amortization, interest-only payments, balloon payments, or terms exceeding 30 years from being qualified mortgages. The rule also establishes general underwriting criteria for qualified mortgages, including that monthly payments be calculated based on the highest payment that will apply in the first five years of the loan and that the borrower have a total debt-to-income ratio that is less than or equal to 43 percent. While “qualified mortgages” will generally be afforded safe harbor status, a rebuttable presumption of compliance with the ability-to-repay requirements will attach to “qualified mortgages” that are “higher priced mortgages” (which are generally subprime loans). In addition, the banking regulators have issued final rules that require the securitizer of asset-backed securities to retain not less than 5 percent of the credit risk of the assets collateralizing the asset-backed securities, unless subject to an exemption for asset-backed securities that are collateralized exclusively by residential mortgages that qualify as “qualified residential mortgages.” These definitions are expected to significantly shape the parameters for the majority of consumer mortgage lending in the U.S.

Reflecting the CFPB's focus on the residential mortgage lending market, the CFPB has also issued rules to implement requirements of the Dodd-Frank Act pertaining to mortgage loan origination (including with respect to loan originator compensation and loan originator qualifications) and has finalized, integrated mortgage disclosure rules that replace and combine certain requirements under the Truth in Lending Act and the Real Estate Settlement Procedures Act and took effect on October 3, 2015. The CFPB has indicated that it expects to issue additional mortgage-related rules in the future.

In addition, there are a number of significant consumer protection standards that apply to functional areas of operation (rather than applying only to loan or deposit products). For example, the Federal Reserve Board issued rules establishing standards for debit card interchange fees and prohibiting network exclusivity arrangements and routing restrictions. The FDIC has also issued rules aimed at protecting consumers in connection with retail foreign exchange transactions.

In recent years, the Federal Reserve Board and the CFPB have made a number of changes to Regulation E. For example, financial institutions are prohibited from charging consumers fees for paying overdrafts on automated teller machine and one-time debit card transactions, unless a consumer consents, or opts in, to the overdraft service for those types of transactions. Regulation E amendments also require financial institutions to provide consumers with a notice that explains the financial institution's overdraft services, including the fees associated with the service and the consumer's choices. Financial institutions also must monitor overdraft payment programs for “excessive or chronic” customer use and undertake “meaningful and effective” follow-up action with customers that overdraw their accounts more than six times during a rolling 12-month period. Furthermore, the CFPB has engaged in studies of overdraft practices and the costs to consumers, and has indicated that it may issue new rules regarding these services.

Regulation E also includes rules for “remittance transfers,” which require financial institutions to provide consumers that transfer funds to overseas recipients with detailed disclosures and to meet other requirements.

It is anticipated that the CFPB will engage in numerous other rulemakings in the near term that may impact our business, as the CFPB has indicated that, in addition to specific statutory mandates, it is working on a wide range of initiatives to address issues in markets for consumer financial products and services. The CFPB has also undertaken an effort to “streamline” consumer regulations and has established a database to collect, track and make public consumer complaints, including complaints against individual financial institutions.

22

The CFPB also has broad authority to prohibit unfair, deceptive or abusive acts and practices and to investigate and penalize financial institutions that violate this prohibition. The CFPB has begun to bring enforcement actions against certain financial institutions for UDAAP violations and issued some guidance on the topic, which provides insight into the agency’s expectations regarding these standards. Among other things, CFPB guidance and its UDAAP-related enforcement actions have emphasized that management of third-party service providers is essential to effective UDAAP compliance and that the CFPB is particularly focused on marketing and sales practices.

We cannot fully predict the effect that being regulated by a new, additional regulatory authority focused on consumer financial protection, or any new implementing regulations or revisions to existing regulations that may result from the establishment of this new authority, will have on Synovus' businesses. Additional regulations resulting from the Dodd-Frank Act and the broad authority of the CFPB could adversely affect Synovus' business, financial condition or results of operations. See “Part 1 - Item 1A. Risk Factors - Regulation of the financial services industry continues to undergo major changes, and future legislation could increase our cost of doing business or harm our competitive position.” of this Report.

In addition, Synovus Bank may also be subject to certain state laws and regulations designed to protect consumers.

Anti-Money Laundering; USA PATRIOT Act; Office of Foreign Assets Control

Financial institutions must maintain anti-money laundering programs that include established internal policies, procedures, and controls; a designated compliance officer; an ongoing employee training program; and testing of the program by an independent audit function. We are prohibited from entering into specified financial transactions and account relationships and must meet enhanced standards for due diligence in dealings with foreign financial institutions and foreign customers. We also must take reasonable steps to conduct enhanced scrutiny of account relationships to guard against money laundering and to report any suspicious transactions. Recent laws provide law enforcement authorities with increased access to financial information maintained by banks. Anti-money laundering obligations have been substantially strengthened as a result of the USA PATRIOT Act, enacted in 2001 and renewed in 2006.

The USA PATRIOT Act amended, in part, the Bank Secrecy Act and provides for the facilitation of information sharing among governmental entities and financial institutions for the purpose of combating terrorism and money laundering. The statute also creates enhanced information collection tools and enforcement mechanics for the U.S. government, including: (1) requiring standards for verifying customer identification at account opening; (2) promulgating rules to promote cooperation among financial institutions, regulators, and law enforcement entities in identifying parties that may be involved in terrorism or money laundering; (3) requiring reports by nonfinancial trades and businesses filed with FinCEN for transactions exceeding $10,000; and (4) mandating the filing of suspicious activity reports if a bank believes a customer may be violating U.S. laws and regulations. The statute also requires enhanced due diligence requirements for financial institutions that administer, maintain, or manage private bank accounts or correspondent accounts for non-U.S. persons.

The Federal Bureau of Investigation may send bank regulatory agencies lists of the names of persons suspected of involvement in terrorist activities. Our banks can be requested to search their records for any relationships or transactions with persons on those lists and may be required to report any identified relationships or transactions. Furthermore, OFAC is responsible for helping to ensure that U.S. entities do not engage in transactions with certain prohibited parties, as defined by various Executive Orders and Acts of Congress. OFAC publishes, and routinely updates, lists of names of persons and organizations suspected of aiding, harboring or engaging in terrorist acts, including the Specially Designated Nationals and Blocked Persons. If we find a name on any transaction, account or wire transfer that is on an OFAC list, we must freeze such account, file a suspicious activity report and notify the appropriate authorities.

Bank regulators routinely examine institutions for compliance with these anti-money laundering obligations and recently have been active in imposing “cease and desist” and other regulatory orders and money penalty sanctions against institutions found to be in violation of these requirements. In addition, the Financial Crimes Enforcement Network, or FinCEN, has issued proposed rules that would require financial institutions to obtain beneficial ownership information for certain accounts; however, it has yet to issue final regulations on this topic.

Commitments to Synovus Bank

Under the Federal Reserve Board's policy and regulation, we are expected to serve as a source of financial and managerial strength to Synovus Bank and to commit resources to support Synovus Bank in circumstances when we might not do so absent such policy. Under the Bank Holding Company Act, the Federal Reserve Board may require a bank holding company to terminate any activity or relinquish control of a nonbank subsidiary, other than a nonbank subsidiary of a bank, upon the Federal Reserve Board's determination that such activity or control constitutes a serious risk to the financial soundness or stability of any depository institution subsidiary. Further, the Federal Reserve Board has discretion to require a bank holding company to divest itself of any bank or non-bank subsidiaries if the agency determines that any such divestiture may aid the depository institution's financial condition. In addition, any loans by us to Synovus Bank would be subordinate in right of payment to depositors and to certain other indebtedness of the bank. Notably, the Dodd-Frank Act codified the Federal Reserve Board's “source of strength” doctrine.

23

In addition to the foregoing requirements, the Dodd-Frank Act's new provisions authorize the Federal Reserve Board to require a company that directly or indirectly controls a bank to submit reports that are designed both to assess the ability of such company to comply with its “source of strength” obligations and to enforce the company's compliance with these obligations. The Federal Reserve Board has not yet issued rules implementing this requirement, though it is understood that regulators are engaged in a joint effort to produce these rules.

If we were to enter bankruptcy or become subject to the orderly liquidation process established by the Dodd-Frank Act, any commitment by us to a federal bank regulatory agency to maintain the capital of Synovus Bank would be assumed by the bankruptcy trustee or the FDIC, as appropriate, and entitled to a priority of payment. In addition, the FDIC provides that any insured depository institution generally will be liable for any loss incurred by the FDIC in connection with the default of, or any assistance provided by the FDIC to, a commonly controlled insured depository institution. Synovus Bank is an FDIC-insured depository institution and thus subject to these requirements.

Transactions with Affiliates and Insiders

A variety of legal limitations restrict Synovus Bank from lending or otherwise supplying funds or in some cases transacting business with us or our non-bank subsidiaries. Synovus Bank is subject to Sections 23A and 23B of the Federal Reserve Act and Federal Reserve Regulation W. Section 23A places limits on the amount of “covered transactions,” which include loans or extensions of credit to, investments in or certain other transactions with, affiliates as well as the amount of advances to third parties collateralized by the securities or obligations of affiliates. The aggregate of all covered transactions is limited to 10 percent of the bank's capital and surplus for any one affiliate and 20 percent for all affiliates. Furthermore, within the foregoing limitations as to amount, certain covered transactions must meet specified collateral requirements ranging from 100 to 130 percent. Also, Synovus Bank is prohibited from purchasing low quality assets from any of its affiliates. Section 608 of the Dodd-Frank Act broadened the definition of “covered transaction” to include derivative transactions and the borrowing or lending of securities if the transaction will cause a bank to have credit exposure to an affiliate. The expanded definition of “covered transaction” also includes the acceptance of debt obligations issued by an affiliate as collateral for a bank's loan or extension of credit to a third-party. Furthermore, reverse repurchase transactions will be viewed as extensions of credit (instead of asset purchases) and thus become subject to collateral requirements. The expanded definition of “covered transaction” took effect on July 21, 2012 under the terms of the Dodd-Frank Act.

Section 23B, among other things, prohibits an institution from engaging in certain transactions with affiliates unless the transactions are on terms substantially the same, or at least as favorable to the bank, as those prevailing at the time for comparable transactions with nonaffiliated companies. Except for limitations on low quality asset purchases and transactions that are deemed to be unsafe or unsound, Regulation W generally excludes affiliated depository institutions from treatment as affiliates. Transactions between a bank and any of its subsidiaries that are engaged in certain financial activities may be subject to the affiliated transaction limits. The Federal Reserve Board also may designate bank subsidiaries as affiliates.

Banks are also subject to quantitative restrictions on extensions of credit to executive officers, directors, principal shareholders, and their related interests. In general, such extensions of credit (1) may not exceed certain dollar limitations, (2) must be made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with third parties and (3) must not involve more than the normal risk of repayment or present other unfavorable features. Certain extensions of credit also require the approval of a bank's Board of Directors.

Regulatory Examinations

Federal and state banking agencies require us and our subsidiary banks to prepare annual reports on financial condition and to conduct an annual audit of financial affairs in compliance with minimum standards and procedures. Synovus Bank, Synovus Trust Company, and in some cases we and our nonbank affiliates, must undergo regular on-site examinations by the appropriate regulatory agency, which will examine for adherence to a range of legal and regulatory compliance responsibilities. A bank regulator conducting an examination has complete access to the books and records of the examined institution. The results of the examination are confidential. The cost of examinations may be assessed against the examined institution as the agency deems necessary or appropriate.

Community Reinvestment Act

The Community Reinvestment Act requires the FDIC to evaluate the record of Synovus Bank in meeting the credit needs of its local community, including low and moderate income neighborhoods. These evaluations are considered in evaluating mergers, acquisitions, and applications to open a branch or facility. Failure to adequately meet these criteria could result in additional requirements and limitations on the bank.

Commercial Real Estate Lending

Lending operations that involve concentrations of commercial real estate loans are subject to enhanced scrutiny by federal banking regulators. The regulators have advised financial institutions of the risks posed by commercial real estate lending

24

concentrations. Such loans generally include land development, construction loans and loans secured by multifamily property, and nonfarm, nonresidential real property where the primary source of repayment is derived from rental income associated with the property. The guidance prescribes the following guidelines for examiners to help identify institutions that are potentially exposed to concentration risk and may warrant greater supervisory scrutiny:

• total reported loans for construction, land development and other land represent 100 percent or more of the institutions total capital, or

• total commercial real estate loans represent 300 percent or more of the institution's total capital, and the outstanding balance of the institution's commercial real estate loan portfolio has increased by 50 percent or more during the prior 36 months.

In addition, the banking regulators have issued final rules that require the securitizer of asset-backed securities to retain not less than 5 percent of the credit risk of the assets collateralizing the asset-backed securities. This may impact our business by reducing the amount of our commercial real estate lending and increasing the cost of borrowing.

Branching

The Dodd-Frank Act substantially amended the legal framework that had previously governed interstate branching activities. Formerly, under the Reigle-Neal Interstate Banking and Branching Efficiency Act of 1994, a bank's ability to branch into a particular state was largely dependent upon whether the state “opted in” to de novo interstate branching. Many states did not “opt-in,” which resulted in branching restrictions in those states. The Dodd-Frank Act removed the “opt-in” concept and permits banks to engage in de novo branching outside of their home states, provided that the laws of the target state permit banks chartered in that state to branch within that state. Accordingly, de novo interstate branching by Synovus Bank is subject to these new standards. All branching in which Synovus Bank may engage remains subject to regulatory approval and adherence to applicable legal and regulatory requirements.

Anti-Tying Restrictions

In general, a bank may not extend credit, lease, sell property, or furnish any services or fix or vary the consideration for them on the condition that (1) the customer obtain or provide some additional credit, property, or services from or to the bank or bank holding company or their subsidiaries or (2) the customer not obtain some other credit, property, or services from a competitor, except to the extent reasonable conditions are imposed to assure the soundness of the credit extended. A bank may, however, offer combined-balance products and may otherwise offer more favorable terms if a customer obtains two or more traditional bank products. The law also expressly permits banks to engage in other forms of tying and authorizes the Federal Reserve Board to grant additional exceptions by regulation or order. Also, certain foreign transactions are exempt from the general rule.

Privacy and Credit Reporting

Financial institutions are required to disclose their policies for collecting and protecting nonpublic customer information obtained from consumers. Customers generally may prevent financial institutions from sharing nonpublic personal financial information with nonaffiliated third parties, with some exceptions, such as the processing of transactions requested by the consumer. Financial institutions generally may not disclose certain consumer or account information to any nonaffiliated third-party for use in telemarketing, direct mail marketing or other marketing. Federal and state banking agencies have prescribed standards for maintaining the security and confidentiality of consumer information, and we are subject to such standards, as well as certain federal and state laws or standards for notifying consumers in the event of a security breach.

Synovus Bank utilizes credit bureau data in underwriting activities. Use of such data is regulated under the Fair Credit Reporting Act and Regulation V on a uniform, nationwide basis, including credit reporting, prescreening, and sharing of information between affiliates and the use of credit data. The Fair and Accurate Credit Transactions Act, which amended the Fair Credit Reporting Act, permits states to enact identity theft laws that are not inconsistent with the conduct required by the provisions of that Act.

Enforcement Powers

Synovus Bank and its “institution-affiliated parties,” including management, employees, agents, independent contractors and consultants, such as attorneys and accountants and others who participate in the conduct of the institution's affairs, are subject to potential civil and criminal penalties for violations of law, regulations or written orders of a government agency. Violations can include failure to timely file required reports, filing false or misleading information or submitting inaccurate reports. Civil penalties may be as high as $1,000,000 a day for such violations and criminal penalties for some financial institution crimes may include imprisonment for 20 years. Regulators have flexibility to commence enforcement actions against institutions and institution-affiliated parties, and the FDIC has the authority to terminate deposit insurance. When issued by a banking agency, cease-and-desist and similar orders may, among other things, require affirmative action to correct any harm resulting from a violation or practice, including restitution, reimbursement, indemnifications or guarantees against loss. A financial institution may also be ordered to restrict its growth, dispose of certain assets, rescind agreements or contracts, or take other actions determined to be

25

appropriate by the ordering agency. The federal banking agencies also may remove a director or officer from an insured depository institution (or bar them from the industry) if a violation is willful or reckless. See “Part I - Item 1A. Risk Factors - We may become subject to supervisory actions and enhanced regulation that could have a material negative effect on our business, reputation, operating flexibility, financial condition and the value of our common stock and preferred stock.” of this Report.

Monetary Policy and Economic Controls

The earnings of Synovus Bank, and therefore our earnings, are affected by the policies of regulatory authorities, including the monetary policy of the Federal Reserve Board. n important function of the Federal Reserve Board is to promote orderly economic growth by influencing interest rates and the supply of money and credit. Among the methods that have been used to achieve this objective are open market operations in U.S. government securities, changes in the discount rate for bank borrowings, expanded access to funds for nonbanks and changes in reserve requirements against bank deposits. These methods are used in varying combinations to influence overall growth and distribution of bank loans, investments and deposits, interest rates on loans and securities, and rates paid for deposits. In response to the financial crisis, the Federal Reserve Board created several innovative programs to stabilize certain financial institutions and to ensure the availability of credit, which the Federal Reserve Board has begun to modify in light of improved economic conditions.

The effects of the various Federal Reserve Board policies on our future business and earnings cannot be predicted. We cannot predict the nature or extent of any effects that possible future governmental controls or legislation might have on our business and earnings.

Depositor Preference Statute

Federal law provides that deposits and certain claims for administrative expenses and employee compensation against an insured depository institution are afforded priority over other general unsecured claims against such institution, including federal funds and letters of credit, in the liquidation or other resolution of the institution by any receiver.

Other Regulatory Matters

Synovus and its subsidiaries and affiliates are subject to numerous examinations by federal and state banking regulators, as well as the SEC, the FINRA, the NYSE and various state insurance and securities regulators. Synovus and its subsidiaries have from time to time received requests for information from regulatory authorities in various states, including state insurance commissions and state attorneys general, securities regulators and other regulatory authorities, concerning their business practices. Such requests are considered incidental to the normal conduct of business.

ITEM 1A. RISK FACTORS

This section highlights the material risks that we currently face. Please be aware that these risks may change over time and other risks may prove to be important in the future. New risks may emerge at any time, and we cannot predict such risks or estimate the extent to which they may affect our business, financial condition or results of operations or the trading price of our securities.

Competition in the financial services industry may adversely affect our future earnings and growth.

We operate in a highly competitive environment and our profitability and our future growth depends on our ability to compete successfully. We face pricing competition for loans and deposits and also with respect to customer convenience, product lines, accessibility of service and service capabilities. Certain of our competitors are larger and have more resources than we do, enabling them to be more aggressive than us in competing for loans and deposits and investing in new products, technology and services. In addition, the ability of non-bank competitors to provide services previously limited to commercial banks has intensified the competition we face. These non-bank competitors are not subject to the same extensive regulations that govern us and, therefore, may be able to operate with greater flexibility and lower cost structures. This significant competition in attracting and retaining deposits and making loans as well as in providing other financial services may impact our future earnings and growth.

We may not realize the expected benefits from our efficiency and growth initiatives, which will negatively impact our future profitability.

In the current competitive banking environment, operating costs must continue to reduce or grow much slower than overall revenue growth. In addition, we must continue to implement strategies to grow our loan portfolio and increase non-interest income in order to realize continued earnings growth and to remain competitive with the other banks in the markets we serve. Since 2010, we have implemented a series of strategic efficiency and growth initiatives to address the challenges facing us and defined strategies for expense reduction, streamlining of processes and long-term growth initiatives. While we have realized cost-savings as a result of various expense savings initiatives, there is no guarantee that these initiatives will be successful in controlling expenses in the future as a number of factors can influence our levels of expenses, many of which are beyond our control. In addition, while expense management continues to be a major focus for us, management also expects to continue to make strategic investments in technology and talent that are expected to improve our customer experience and support future growth. There can be no assurance that we will ultimately realize the anticipated benefits of our expense reduction and growth strategies, which may impair our earnings growth.

In addition, we are is subject to various risks inherent in our business. These risks may cause the anticipated results from our growth strategies and cost-reduction initiatives to result in implementation charges beyond those currently contemplated or could result in some other unanticipated adverse impact. Furthermore, if we do not realize the anticipated cost-savings from our efficiency initiatives, we may need to take additional actions to achieve the desired cost-savings. The implementation of these initiatives may also have unintended impacts on our ability to attract and retain business and customers. Accordingly, we cannot guarantee that the anticipated long-term benefits from our efficiency and growth initiatives will be realized, and if they are not we may not achieve our strategic and financial objectives.

If our enterprise risk management framework is not effective at mitigating risk and loss to us, we could suffer unexpected losses and our results of operations could be materially adversely affected.

Our enterprise risk management framework seeks to achieve an appropriate balance between risk and return, which is critical to optimizing shareholder value. We have established processes and procedures intended to identify, measure, monitor, report and analyze the types of risk to which we are subject, including credit, liquidity, operational, regulatory compliance and reputational. However, as with any risk management framework, there are inherent limitations to our risk management strategies as there may exist, or develop in the future, risks that we have not appropriately anticipated or identified. For example, the financial and credit crisis and resulting regulatory reform highlighted both the importance and some of the limitations of managing unanticipated risks. If our risk management framework proves ineffective, we could suffer unexpected losses and our business and results of operations could be materially adversely affected.

Our allowance for loan losses may not cover actual losses, and we may be required to materially increase our allowance, which may adversely affect our capital, financial condition and results of operations.

We derive the most significant portion of our revenues from our lending activities. When we lend money, commit to lend money or enter into a letter of credit or other contract with a counterparty, we incur credit risk, which is the risk of losses if our borrowers do not repay their loans or our counterparties fail to perform according to the terms of their contracts. We estimate and maintain an allowance for loan losses, which is a reserve established through a provision for loan losses charged to expenses, which represents management's best estimate of probable credit losses that have been incurred within the existing portfolio of loans, as described under Note 5 of Notes to Consolidated Financial Statements in this Report and under “Critical Accounting Policies - Allowance for Loan Losses” under “Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations” of this Report. The allowance, in the judgment of management, is established to reserve for estimated loan losses and risks inherent in the loan portfolio. The determination of the appropriate level of the allowance for loan losses inherently

27

involves a high degree of subjectivity and requires us to make significant estimates of current credit risks using existing qualitative and quantitative information, all of which may undergo material changes. Changes in economic conditions affecting borrowers, new information regarding existing loans, identification of additional problem loans, risk ratings, and other factors, both within and outside of our control, may require an increase in the allowance for loan losses.

Because the risk rating of the loans is dependent on certain subjective information and is subject to changes in the borrower's credit risk profile, evolving local market conditions and other factors, it can be difficult for us to predict the effects that those factors will have on the classifications assigned to the loan portfolio, and thus difficult to anticipate the velocity or volume of the migration of loans through the classification process and effect on the level of the allowance for loan losses. Accordingly, we monitor our credit quality and our reserve requirements and use that as a basis for capital planning and other purposes. See “Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity” and “Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Capital Resources” of this Report for further information.

Future additions to the allowance may be necessary based on changes in the economic environment as well as changes in assumptions regarding a borrower's ability to pay and/or collateral values. In addition, various regulatory agencies, as an integral part of their examination procedures, periodically review the allowance. Based on their judgments about information available to them at the time of their examination, such agencies may require us to recognize additions to the allowance or additional loan charge offs. An increase in the allowance for loan losses would result in a decrease in net income and capital, and could have a material adverse effect on our capital, financial condition and results of operations.

Any future economic downturn could have a material adverse effect on our capital, financial condition, results of operations, and future growth.

Management continually monitors market conditions and economic factors throughout the footprint. If these conditions were to worsen, then we could see a sharp increase in our total net charge-offs and also be required to significantly increase our allowance for loan losses. Furthermore, the demand for loans and our other products and services could decline. An increase in our non-performing assets and related increases in our provision for loan losses, coupled with a potential decrease in the demand for loans and our other products and services, could negatively affect our business and could have a material adverse effect on our capital, financial condition, results of operations and future growth.

Our net interest income could be negatively affected by the low level of short-term interest rates and a decrease in total loans.

Net interest income, which is the difference between the interest income that we earn on interest-earning assets and the interest expense that we pay on interest-bearing liabilities, is a major component of our income and our primary source of revenue from our operations. The narrowing of interest rate spreads could adversely affect our earnings and financial condition. While we anticipate slight increases in interest rates in 2016, we expect rates to remain at historically low levels in 2016. Furthermore, we cannot control or predict with certainty changes in interest rates. Regional and local economic conditions, competitive pressures and the policies of regulatory authorities, including monetary policies of the FRB, affect interest income and interest expense. We have ongoing policies and procedures designed to manage the risks associated with changes in market interest rates. However, changes in interest rates still may have an adverse effect on our profitability. A significant portion of our loans, including commercial real estate loans and commercial and industrial loans, bear interest at variable rates. In addition, in order to compete for deposits in our primary market areas, we may offer more attractive interest rates to depositors, or we may have to pursue other sources of liquidity, such as wholesale funds. While we actively manage against these risks through hedging and other risk mitigation strategies, if our assumptions are wrong or overall economic conditions are significantly different than anticipated, our risk mitigation techniques may be insufficient.

Our net interest income was $827.3 million for 2015, an increase of 1.0% compared to $819.3 million for 2014. Our total loans were $22.43 billion as of December 31, 2015 compared to $21.10 billion as of December 31, 2014. Any future decrease in loan yields or lower realized yields on investment securities could reduce our net interest income and could cause additional pressure on net interest income in future periods. This reduction in net interest income also may be exacerbated by the high level of competition that we face in our primary market area. Significant reduction in our net interest income could have a material adverse impact on our capital, financial condition and results of operations.

The financial services market is undergoing rapid technological changes, and if we are unable to stay current with those changes, we will not be able to effectively compete.

The financial services market, including banking services, is undergoing rapid changes with frequent introductions of new technology-driven products and services. Our future success will depend, in part, on our ability to keep pace with the technological changes and to use technology to satisfy and grow customer demand for our products and services and to create additional efficiencies in our operations. We expect that we will need to make substantial investments in our technology and information systems to compete effectively and to stay current with technological changes. Some of our competitors have substantially greater resources to invest in technological improvements and will be able to invest more heavily in developing and adopting new

28

technologies, which may put us at a competitive disadvantage. We may not be able to effectively implement new technology-driven products and services or be successful in marketing these products and services to our customers. As a result, our ability to effectively compete to retain or acquire new business may be impaired, and our business, financial condition or results of operations may be adversely affected.

We rely extensively on information technology systems to operate our business and an interruption or security breach may disrupt our business operations, result in reputational harm and have an adverse effect on our operations.

As a large financial institution, we rely extensively on our information technology systems to operate our business, including to process, record and monitor a large number of customer transactions on a continuous basis. As customer, public and regulatory expectations regarding operational and information security have increased, our operational systems and infrastructure must continue to be safeguarded and monitored for potential failures, disruptions and breakdowns. Our business, financial, accounting, data processing systems or other operating systems and facilities may stop operating properly or become disabled or damaged as a result of a number of factors including events that are wholly or partially beyond our control. For example, there could be sudden increases in customer transaction volume; electrical or telecommunications outages; natural disasters such as earthquakes, tornadoes, and hurricanes; disease pandemics; events arising from local or larger scale political or social matters, including terrorist acts; and, as described below, cyber-attacks.

We have policies, procedures and systems designed to prevent or limit the effect of possible failures, interruptions or breaches in security of information systems and business continuity programs designed to provide services in the case of an event resulting in material disruptions of our operating systems. We regularly seek to test the effectiveness of and enhance these policies, procedures and systems. However, there is no guarantee that these safeguards or programs will address all of the threats that continue to evolve. The occurrence of any failure, interruption or security breach of any of our operating systems, or the systems of other companies on which we rely, could result in a wide variety of adverse consequences to us, including disruptions to our business operations, damage to our reputation, loss of customers, liabilities to us and increased regulatory scrutiny.

We face significant cyber and data security risk that could result in the disclosure of confidential information, adversely affect our business or reputation and expose us to significant liabilities.

As a large financial institution, we are under continuous threat of loss due to the velocity and sophistication of cyber-attacks. This risk continues to increase. Two of the most significant cyber-attack risks that we face are e-fraud and loss of sensitive customer data. Loss from e-fraud occurs when cybercriminals breach and extract funds directly from customer or our accounts. The attempts to breach sensitive customer data, such as account numbers and social security numbers, would present significant reputational, legal and/or regulatory costs to us if successful. Our risk and exposure to these matters remains heightened because of the evolving nature and complexity of these threats from cybercriminals and hackers, our plans to continue to provide internet banking and mobile banking channels, and our plans to develop additional remote connectivity solutions to serve our customers. While we have not experienced any material losses relating to cyber-attacks or other information security breaches to date, we have been the subject of attempted hacking and cyber-attacks and there can be no assurance that we will not suffer such losses in the future.

The occurrence of any cyber-attack or information security breach could result in material adverse consequences to us including damage to our reputation and the loss of customers. We also could face litigation or additional regulatory scrutiny. Litigation or regulatory actions in turn could lead to significant liability or other sanctions, including fines and penalties or reimbursement to customers adversely affected by a security breach. Even if we do not suffer any material adverse consequences as a result of events affecting us directly, successful attacks or systems failures at other large financial institutions could lead to a general loss of customer confidence in financial institutions including us.

We continually review the security of our IT systems and make the necessary investments to improve the resiliency of our systems and their security from attack. Nonetheless, there remains the risk that we may be materially harmed by a cyber-attack or information security breach. Attack methods continue to evolve in sophistication, velocity, and frequency and can occur from a variety of sources, such as foreign governments, hacktivists, or other well-financed entities, and may originate from less regulated and remote areas of the world. As a result, if such an attack or breach does occur, we will take reasonable and customary measures to address the situation, based on our crisis management plan.

We rely on other companies to provide key components of our business infrastructure.

Third parties provide key components of our business operations such as data processing, recording and monitoring transactions, online banking interfaces and services, Internet connections and network access. While we have selected these third-party vendors carefully, we do not control their actions. Any problems caused by these third parties, including those resulting from disruptions in communication services provided by a vendor, failure of a vendor to handle current or higher volumes, cyber-attacks and security breaches at a vendor, failure of a vendor to provide services for any reason or poor performance of services, could adversely affect our ability to deliver products and services to our customers and otherwise conduct our business. Financial or operational difficulties of a third-party vendor could also hurt our operations if those difficulties interfere with the vendor's

29

ability to serve us. Furthermore, our vendors could also be sources of operational and information security risk to us, including from breakdowns or failures of their own systems or capacity constraints. Replacing these third-party vendors could also create significant delay and expense. Accordingly, use of such third parties creates an unavoidable inherent risk to our business operations.

We may not be able to attract and retain key employees, which may adversely impact our ability to successfully execute our growth strategies.

Our financial success depends upon our ability to attract and retain highly motivated, well-qualified personnel. We face significant competition in the recruitment of qualified employees from financial institutions and others. If we are unable to attract and retain qualified employees, our ability to execute our business strategies may suffer and we may be required to substantially increase our overall compensation or benefits to attract and retain such employees. Furthermore, in June 2010, the Federal Reserve, the Office of the Comptroller of the Currency, the Office of Thrift Supervision, and the FDIC jointly issued comprehensive final guidance designed to ensure that incentive compensation policies do not undermine the safety and soundness of banking organizations by encouraging employees to take imprudent risks. This regulation significantly restricts the amount, form, and context in which we pay incentive compensation and may put us at a competitive disadvantage compared to non-financial institutions in terms of attracting and retaining senior level employees.

We could realize losses if we determine to sell non-performing assets and the proceeds we receive are lower than the carrying value of such assets.

We could realize future losses if the proceeds we receive upon dispositions of non-performing assets are lower than the recorded carrying value of such assets, which could adversely affect our results of operations in future periods. Accordingly, we could realize an increased level of credit costs in any period during which we determine to dispose of an increased level of distressed assets. Further, although market conditions have improved, if market conditions experience another downturn, this could negatively impact our ability to dispose of distressed assets, and may result in higher credit losses on sales of distressed assets.

We are subject to a variety of operational risks, including reputational risk, legal risk, and regulatory and compliance risk, and the risk of fraud or theft by employees or outsiders, which may adversely affect our business and results of operations.

We are exposed to many types of operational risks, including reputational risk, legal and regulatory and compliance risk, the risk of fraud or theft by employees or outsiders, including unauthorized transactions by employees or operational errors, clerical or record-keeping errors or those resulting from faulty or disabled computer or telecommunications systems. See “Part I - Item 1. Business - Enterprise Risk Management” of this Report for further information. Negative public opinion may result from our actual or alleged conduct in any number of activities, including lending practices, corporate governance and acquisitions and from actions taken by government regulators and community organizations in response to those activities. Negative public opinion may adversely affect our ability to attract and keep customers and can expose us to litigation and regulatory action. Actual or alleged conduct by us may result in negative public opinion about our business. Negative public opinion may also affect our credit ratings, which are important to our access to unsecured wholesale borrowings.

Our business involves storing and processing sensitive consumer and business customer data. If personal, non-public, confidential or proprietary information of customers in our possession were to be mishandled or misused, we may suffer significant regulatory consequences, reputational damage and financial loss. Such mishandling or misuse could include, for example, if such information were erroneously provided to parties who are not permitted to have the information, either by fault of our systems, employees, or counterparties, or where such information is intercepted or otherwise inappropriately taken by third parties. Furthermore, a cyber security breach could result in theft of such data.

Because the nature of the financial services business involves a high volume of transactions, certain errors may be repeated or compounded before they are discovered and successfully rectified. Our necessary dependence upon automated systems to record and process transactions, and our large transaction volume may further increase the risk that technical flaws or employee tampering or manipulation of those systems will result in losses that are difficult to detect. We also may be subject to disruptions of our operating systems arising from events that are wholly or partially beyond our control (for example, computer viruses, cyber-attacks or electrical or telecommunications outages, or natural disasters, disease pandemics or other damage to property or physical assets) which may give rise to disruption of service to customers and to financial loss or liability. We are further exposed to the risk that our external vendors may be unable to fulfill their contractual obligations (or will be subject to the same risk of fraud or operational errors by their respective employees as we are) and to the risk that our (or our vendors') business continuity and data security systems prove to be inadequate. The occurrence of any of these risks may result in a diminished ability of us to operate our business (for example, by requiring us to expend significant resources to correct the defect), as well as potential liability to clients, reputational damage and regulatory intervention, which may adversely affect our business, financial condition or results of operations, perhaps materially.

30

As an issuer of credit and debit cards we are exposed to losses in the event that holders of our cards experience fraud on their card accounts.

Our customers regularly use Synovus-issued credit and debit cards to pay for transactions with retailers and other businesses. There is the risk of data security breaches at these retailers and other businesses that could result in the misappropriation of our customers’ credit and debit card information. When our customers use Synovus-issued cards to make purchases from those businesses, card account information is provided to the business. If the business’s systems that process or store card account information are subject to a data security breach, holders of our cards who have made purchases from that business may experience fraud on their card accounts. We may suffer losses associated with reimbursing our customers for such fraudulent transactions on customers’ card accounts, as well as for other costs related to data security compromise events, such as replacing cards associated with compromised card accounts. In addition, we provide card transaction processing services to some merchant customers under agreements we have with payment networks such as Visa and MasterCard. Under these agreements, we may be responsible for certain losses and penalties if one of our merchant customers suffers a data security breach.

In the last three years, a number of large retailers suffered substantial data security breaches compromising millions of credit and debit card accounts. To date, our losses and costs related to these breaches have not been material, but other similar events in the future could be more significant to us.

If we pursue acquisitions in the future as part of our growth strategy, we may not be able to complete such acquisitions or successfully integrate bank or nonbank acquisitions into our existing operations.

While we have historically grown by acquisition, we have not completed any acquisitions since the economic downturn. As we have returned to profitability, we may pursue acquisitions of bank or non-bank operations as a growth strategy. However, we may not be successful in identifying suitable acquisition candidates, and even if we identify such candidates, we may not be successful in completing such acquisitions on favorable terms, if at all.

In particular, difficulties may arise in the integration of the business and operations of BHCs, banks and other non-bank entities we acquire and, as a result, we may not be able to achieve the cost savings and synergies that we expect will result from such transactions. Achieving cost savings is dependent on consolidating certain operational and functional areas, eliminating duplicative positions and terminating certain agreements for outside services. Additional savings are dependent upon the integration of the acquired entity’s businesses with our businesses, the conversion of core operating systems, data systems and products and the standardization of business practices. The integration could result in higher than expected deposit attrition, loss of key employees, disruption of our businesses or the businesses of the acquired company, or otherwise adversely affect our ability to maintain relationships with customers and employees or achieve the anticipated benefits of the acquisition.

In addition, we must generally satisfy a number of meaningful conditions before we can complete an acquisition of another bank or BHC, including federal and/or state regulatory approvals. Also, under the Dodd-Frank Act, U.S. regulators must now take systemic risk into account when evaluating whether to approve a potential acquisition transaction. We cannot be certain when or if, or on what terms and conditions, any required regulatory approvals will be granted.

The fiscal and monetary policies of the federal government and its agencies could have a material adverse effect on our earnings.

The Federal Reserve Board regulates the supply of money and credit in the U.S. Its policies determine in large part the cost of funds for lending and investing and the return earned on those loans and investments, both of which affect our net interest margin. They can also materially decrease the value of financial assets we hold. Federal Reserve policies may also adversely affect borrowers, potentially increasing the risk that they may fail to repay their loans, or could adversely create asset bubbles which result from prolonged periods of accommodative policy. This, in turn, may result in volatile markets and rapidly declining collateral values. Changes in Federal Reserve policies are beyond our control and difficult to predict; consequently, the impact of these changes on our activities and results of operations is difficult to predict. Also, potential new taxes on corporations generally, or on financial institutions specifically, would adversely affect our net income.

We may become subject to supervisory actions and enhanced regulation that could have a material negative effect on our business, reputation, operating flexibility, financial condition and the value of our common stock and preferred stock.

Under federal and state laws and regulations pertaining to the safety and soundness of insured depository institutions, state banking regulators, the Federal Reserve, and separately the FDIC as the insurer of bank deposits, each has the authority to compel or restrict certain actions on our part if any of them determine that we have insufficient capital or are otherwise operating in a manner that may be deemed to be inconsistent with safe and sound banking practices. In addition to examinations for safety and soundness, we and our subsidiaries also are subject to continuous examination by state and federal banking regulators, including the CFPB, for compliance with various laws and regulations, as well as consumer compliance initiatives. As a result of this regulatory oversight and examination process, our regulators may require us to enter into informal or formal supervisory agreements, including board resolutions, memoranda of understanding, written agreements and consent or cease and desist orders, pursuant to which we could be required to take identified corrective actions to address cited concerns, or to refrain from taking certain actions.

31

If we become subject to and are unable to comply with the terms of any future regulatory actions or directives, supervisory agreements, or orders, then we could become subject to additional, heightened supervisory actions and orders, possibly including consent orders, prompt corrective action restrictions and/or other regulatory actions, including prohibitions on the payment of dividends on our common stock and Series C Preferred Stock. If our regulators were to take such additional supervisory actions, then we could, among other things, become subject to significant restrictions on our ability to develop any new business, as well as restrictions on our existing business, and we could be required to raise additional capital, discontinue our share repurchase program, dispose of certain assets and liabilities within a prescribed period of time, or all of the above. The terms of any such supervisory action could have a material negative effect on our business, reputation, operating flexibility, financial condition and the value of our common stock. See “Part I - Item 1. Business - Supervision, Regulation, and Other Factors” in this Report for further information

Regulation of the financial services industry continues to undergo major changes, and future legislation could increase our cost of doing business or harm our competitive position.

The Dodd-Frank Act brought about a significant overhaul of many aspects of the regulation of the financial services industry, addressing, among other things, systemic risk, capital adequacy, deposit insurance assessments, consumer financial protection, interchange fees, derivatives, lending limits, mortgage lending practices, registration of investment advisors and changes among the bank regulatory agencies. Key provisions of the Dodd-Frank Act that have impacted or are likely to impact the operations of Synovus Bank or Synovus include:

• Creation of the CFPB with centralized authority, including examination and enforcement authority, for consumer protection in the banking industry.

• New limitations on federal preemption.

• New prohibitions and restrictions on the ability of a banking entity and nonbank financial company to engage in proprietary trading and have certain interests in, or relationships with, a hedge fund or private equity fund (the “Volcker Rule”).

• Application of new regulatory capital requirements, including changes to leverage and risk-based capital standards and changes to the components of permissible tiered capital.

• Requirement that the company and its subsidiary bank be well capitalized and well managed in order to engage in activities permitted for financial holding companies.

• Changes to the assessment base for deposit insurance premiums.

• Permanently raising the FDIC's standard maximum deposit insurance amount to a $250,000 limit for federal deposit insurance.

• Repeal of the prohibition on the payment of interest on demand deposits, thereby permitting depository institutions to pay interest on business transaction and other accounts.

• Restrictions on compensation, including a prohibition on incentive-based compensation arrangements that encourage inappropriate risk taking by covered financial institutions and are deemed to be excessive, or that may lead to material losses.

• Requirement that sponsors of asset-backed securities retain a percentage of the credit risk of the assets underlying the securities.

• Requirement that banking regulators remove references to and requirements of reliance upon credit ratings from their regulations and replace them with appropriate alternatives for evaluating credit worthiness.

• Rules pertaining to a mortgage borrower’s ability to repay, mortgage loan originator compensation and qualifications, and integrated mortgage disclosure rules that will replace and combine certain existing requirements under the Truth in Lending Act and the Real Estate Settlement Procedures Act, among other requirements affecting the mortgage origination and secondary marketing of mortgages.

Some of these and other major changes could materially impact the profitability of our business, the value of assets we hold or the collateral available for our loans, require changes to business practices or force us to discontinue businesses and expose us to additional costs, taxes, liabilities, enforcement actions and reputational risk. Many of these provisions became effective upon enactment of the Dodd-Frank Act, while others were subject to further study, rulemaking, and the discretion of regulatory bodies and have only recently taken effect or will take effect in coming years. In light of these significant changes and the discretion afforded to federal regulators, we cannot fully predict the effect that compliance with the Dodd-Frank Act or any implementing regulations will have on our businesses or our ability to pursue future business opportunities. Additional regulations resulting from the Dodd-Frank Act may materially adversely affect our business, financial condition or results of operations.

Certain other reform proposals have resulted in us becoming subject to stricter capital requirements and leverage limits, and affect the scope, coverage, or calculation of capital, all of which could require us to reduce business levels or to raise capital, including in ways that may adversely impact our shareholders or creditors. See “Part I - Item 1. Business - Supervision, Regulation

32

and Other Factors” of this Report for further information. We cannot predict whether new legislation will be enacted and, if enacted, the effect that it, or any regulations, would have on our business, financial condition, or results of operations.

We may be required to undertake additional strategic initiatives to improve our capital position due to changes in economic conditions or changes in regulatory capital rules.

Effective January 1, 2015, the regulatory capital framework changed for us in important respects as a result of the new rules implementing the Dodd-Frank Act and a separate, international regulatory capital initiative known as “Basel III” (collectively, the “Basel III Capital Rules”). Among other things, the Basel III Capital Rules raised the minimum thresholds for required capital and revised certain aspects of the definitions and elements of the capital that can be used to satisfy these required minimum thresholds. The Basel III Capital Rules also introduced a minimum “capital conservation buffer” equal to 2.5% of an organization’s total risk-weighted assets, which exists in addition to the required minimum CET1, Tier 1 and Total Capital ratios identified above. The “capital conservation buffer,” which must consist entirely of CET1, is designed to absorb losses during periods of economic stress. The implementation of the capital conservation buffer began on January 1, 2016 at the 0.625% level and will be phased-in over a three-year period (increasing by that amount on each subsequent January 1, until it reaches 2.5% on January 1, 2019). In October 2015, we implemented a new capital plan designed to return capital to our shareholders, including the repurchase of up to $300 million of capital stock and an increase in the quarterly dividend payable to holders of our common stock. In addition, during the fourth quarter of 2015, we issued $250 million in subordinated debt and repurchased $46.7 million of our outstanding subordinated notes that mature in 2017. As a result and as of December 31, 2015, our CET1 ratio under Basel III was 9.77% on a fully phased-in basis, which is in excess of the minimum common equity and additional conservation buffer stipulated by the Basel III Capital Rules. See "Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Capital Resources" and "Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Non-GAAP Financial Measures" of this Report for further information.

We and Synovus Bank are also subject to stress testing requirements, including public disclosures of certain results. The results of such stress testing may require us to take certain actions to improve our capital position. See “Part I - Item 1. Business - Supervision, Regulation and Other Factors” of this Report for further information.

Moreover, the federal bank regulators have issued a series of guidance and rulemakings applicable to large banks. While many of these do not currently apply to us due to our asset size, these issuances could impact industry capital standards and practices in many potentially unforeseeable ways.

We continue to actively monitor economic conditions, evolving industry capital standards, and changes in regulatory standards and requirements, and engage in regular discussions with our regulators regarding capital at both Synovus and Synovus Bank. As part of our ongoing management of capital, we will continue to identify, consider, and pursue additional strategic initiatives to bolster our capital position as deemed necessary, including strategies that may be required to meet the requirements of Basel III and other regulatory initiatives regarding capital, and will continue to evaluate our share repurchase program and increased dividends. The need to maintain more capital and greater liquidity than has been required historically could limit our business activities, including lending, and our ability to expand, either organically or through future acquisitions. It could also result in us taking steps to increase our capital that may be dilutive to shareholders or limit our ability to pay dividends or otherwise return capital to shareholders.

Changes in the cost and availability of funding due to changes in the deposit market and credit market, or the way in which we are perceived in such markets, may adversely affect our capital resources, liquidity and financial results.

We may be unable to access historical and alternative sources of liquidity, including the capital markets, brokered deposits, and borrowings from the FHLB, which could adversely affect our overall liquidity. Liquidity represents the extent to which we have readily available sources of funding needed to meet the needs of our depositors, borrowers and creditors, to support asset growth, and to otherwise sustain our operations and the operations of our subsidiary bank. In managing our consolidated balance sheet, we depend on access to a variety of sources of funding to provide us with sufficient capital resources and liquidity to meet our commitments and business needs, and to accommodate the transaction and cash management needs of our customers. Sources of funding available to us, and upon which we rely as regular components of our liquidity and funding management strategy, include borrowings from the FHLB and brokered deposits. See “Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity” and “Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Capital Resources” of this Report for further information. We also have historically enjoyed a solid reputation in the capital markets and have been able to raise funds in the form of either short- or long-term borrowings or equity or debt issuances. If, due to market disruptions, perceptions about our credit ratings or other factors, we are unable to access the capital markets in the future, our capital resources and liquidity may be adversely affected.

In general, the amount, type and cost of our funding, including from other financial institutions, the capital markets and deposits, directly impacts our costs in operating our business and growing our assets and can therefore positively or negatively affect our financial results. A number of factors could make funding more difficult, more expensive or unavailable on any terms, including, but not limited to, a downgrade in our credit ratings, financial results, changes within our organization, specific events

33

that adversely impact our reputation, disruptions in the capital markets, specific events that adversely impact the financial services industry, counterparty availability, changes affecting our assets, the corporate and regulatory structure, interest rate fluctuations, general economic conditions and the legal, regulatory, accounting and tax environments governing our funding transactions. Also, we compete for funding with other banks and similar companies, many of which are substantially larger, and have more capital and other resources than we do. In addition, as some of these competitors consolidate with other financial institutions, these advantages may increase. Competition from these institutions may increase the cost of funds.

In addition to bank level liquidity management, we must manage liquidity at the Parent Company for various needs including potential capital infusions into subsidiaries, the servicing of debt, the payment of dividends on our common stock and preferred stock and share repurchases. The primary source of liquidity for us consists of dividends from Synovus Bank which is governed by certain rules and regulations of our supervising agencies. During 2014, Synovus Bank made upstream cash distributions to the Parent Company totaling $182.0 million including cash dividends of $90.6 million. During 2015, Synovus Bank made upstream cash distributions to the Parent Company totaling $225.0 million including cash dividends of $199.9 million. On February 12, 2016, Synovus Bank paid an upstream cash dividend of $100.0 million to the Parent Company. Synovus' ability to receive dividends from Synovus Bank in future periods will depend on a number of factors, including, without limitation, Synovus Bank's future profits, asset quality, liquidity and overall condition. In addition, GA DBF rules and related statutes contain additional restrictions on payments of dividends by Synovus Bank. In particular, the Georgia Financial Institutions Code contains restrictions on the ability of a Georgia bank to pay dividends other than from retained earnings and under other circumstances without the approval of the GA DBF. As a result of these restrictions, Synovus Bank may be required to seek approval from the GA DBF to pay dividends. See “Part I - Item 1A. Risk Factors -We may not be able to generate sufficient cash to service all of our debt and repay maturing debt obligations.” of this Report. See "Part I - Item 1. Business - Supervision, Regulatory and Other Factors - Dividends" of this Report for further information. Synovus expects that it will receive additional dividends from Synovus Bank in 2016. If Synovus does not receive dividends from Synovus Bank in 2016 at the levels anticipated, its liquidity could be adversely affected and it may not be able to continue to execute its current capital plan to return capital to its shareholders. In addition to dividends from Synovus Bank, we have historically had access to a number of alternative sources of liquidity, including the capital markets, but there is no assurance that we will be able to obtain such liquidity on terms that are favorable to us, or at all. If our access to these traditional and alternative sources of liquidity is diminished or only available on unfavorable terms, then our overall liquidity and financial condition will be adversely affected.

Further downgrades of U.S. government securities by one or more of the credit ratings agencies could have a material effect on our operations, earnings, and financial condition.

In 2011, the S&P credit rating agency lowered its long term sovereign credit rating on the United States from AAA to AA+, which reflected S&P's view that an August 2011 agreement of U.S. lawmakers regarding the debt ceiling fell short of what would be necessary to stabilize the U.S. government's medium term debt dynamics. In June 2013, S&P reaffirmed that rating, while raising its outlook from "Negative" to "Stable". The three other major credit rating agencies did not downgrade their previously issued U.S. sovereign credit ratings, though some have issued negative outlooks at various times over the last several years. While the risk of a sovereign credit ratings downgrade of the U.S. government, including the rating of U.S. Treasury securities, has been reduced, the possibility still remains. It is foreseeable that the ratings and perceived creditworthiness of instruments issued, insured or guaranteed by institutions or agencies directly linked to the U.S. government could also be correspondingly affected by any such downgrade. Instruments of this nature are key assets on the balance sheets of financial institutions to meet their day-to-day cash flow needs in the short-term debt market.

A possible future downgrade of the sovereign credit ratings of the U.S. government and a decline in the perceived creditworthiness of U.S. government-related obligations could impact our ability to obtain funding that is collateralized by affected instruments, as well as affect the pricing of that funding when it is available. A downgrade may also adversely affect the market value of such instruments. We cannot predict if, when or how any changes to the credit ratings or perceived creditworthiness of these organizations will affect economic conditions. Such ratings actions could result in a significant adverse impact on us. A downgrade of the sovereign credit ratings of the U.S. government or the credit ratings of related institutions, agencies, or instruments could exacerbate the other risks to which we are subject and any related adverse effects on the business, financial condition and results of operations.

If Synovus Bank is unable to grow its deposits, it may be subject to paying higher funding costs.

The total amount that we pay for funding costs is dependent, in part, on Synovus Bank’s ability to grow its deposits. If Synovus Bank is unable to sufficiently grow its deposits to meet liquidity needs, it may be subject to paying higher funding costs to meet these liquidity needs. Synovus Bank competes with banks and other financial services companies for deposits. If competitors raise the rates they pay on deposits, Synovus Bank’s funding costs may increase, either because Synovus Bank raises rates to avoid losing deposits or because Synovus Bank loses deposits and must rely on more expensive sources of funding. Higher funding costs reduce our net interest margin and net interest income. Synovus Bank’s customers could take their money out of the bank and put it in alternative investments, causing Synovus Bank to lose a lower cost source of funding. Checking and savings account

34

balances and other forms of customer deposits may decrease when customers perceive alternative investments, such as the stock market, as providing a better risk/return tradeoff.

We may not be able to generate sufficient cash to service all of our debt and repay maturing debt obligations.

As of December 31, 2015, we and our consolidated subsidiaries had $2.19 billion of long-term debt outstanding. Our ability to make scheduled payments of principal and interest or to satisfy our obligations in respect of our debt, to refinance our debt or to fund capital expenditures will depend on our future financial and operating performance and our ability to maintain adequate liquidity. Prevailing economic conditions (including interest rates), regulatory constraints, including, among other things, on distributions to us from our subsidiaries and required capital levels with respect to our subsidiary bank and financial subsidiaries, business and other factors, many of which are beyond our control, may also affect our ability to meet these needs. We may not be able to generate sufficient cash flows from operations, or obtain future borrowings in an amount sufficient to enable us to pay our debt, or to fund our other liquidity needs. We may need to refinance all or a portion of our debt on or before maturity, and we may not be able to refinance any of our debt when needed on commercially reasonable terms or at all. If our cash flow and capital resources are insufficient to fund our debt obligations, we may be forced to reduce or delay investments in our business, sell assets, seek to obtain additional equity or debt financing or restructure our debt on terms that may not be favorable to us.

We may be unable to pay dividends on our common stock and Series C Preferred Stock.

Holders of our common stock and Series C Preferred Stock are only entitled to receive such dividends as our Board of Directors may declare out of funds legally available for such payments. Although we have historically paid a quarterly cash dividend to the holders of our common stock and Series C Preferred Stock, we are not legally required to do so. Further, the Federal Reserve could decide at any time that paying any dividends on our common stock or preferred stock could be an unsafe or unsound banking practice. The reduction or elimination of dividends paid on our common stock or preferred stock could adversely affect the market price of our common stock or preferred stock, as applicable. In addition, if we fail to pay dividends on our Series C Preferred Stock for six quarters, whether or not consecutive, the holders of the Series C Preferred Stock shall be entitled to certain rights to elect two directors to our Board of Directors.

For a discussion of current regulatory limits on our ability to pay dividends, see “Part I - Item 1. Business - Supervision, Regulation and Other Factors - Dividends,” “Part I - Item 1A - Risk Factors - We may become subject to supervisory actions and enhanced regulation that could have a material negative effect on our business, reputation, operating flexibility, financial condition and the value of our common stock and preferred stock.” and “Part II - Item 5. Market for Registrant's Common Equity, Related Stockholder Matters and Issuer Repurchases of Equity Securities - Dividends” in this Report for further information.

We may be required to repurchase mortgage loans or indemnify mortgage loan purchasers as a result of breaches of representations and warranties, borrower fraud, or certain borrower defaults, which could harm our liquidity, results of operations and financial condition.

Synovus Mortgage sells the majority of all the mortgage loans that it originates. While the loans are sold without recourse, the purchase agreements require Synovus Mortgage to make certain representations and warranties regarding the existence and sufficiency of file documentation and the absence of fraud by borrowers or other third parties such as appraisers in connection with obtaining the loan. If it is determined that loans sold were in breach of these representations or warranties, Synovus Mortgage has obligations to either repurchase the loan at the unpaid principal balance and related investor fees or make the purchaser whole for any economic losses associated with the loan. In addition, the Dodd-Frank Act contains provisions designed to address perceived deficiencies in the residential mortgage loan origination and underwriting process, in part by creating new documentation requirements and underwriting criteria and increasing the potential liability of Synovus and Synovus Mortgage to their customers if Synovus and Synovus Mortgage fail to take steps to ensure and document that each borrower has the capacity and the ability to repay their loans.

To date, repurchase activity pursuant to the terms of these representations and warranties has been minimal and has primarily been associated with loans originated from 2005 through 2008. From January 1, 2005 through December 31, 2015, Synovus Mortgage originated and sold approximately $8.9 billion of first lien GSE eligible mortgage loans and approximately $3.9 billion of first and second lien non-GSE eligible mortgage loans. The total expense pertaining to losses from repurchases of mortgage loans previously sold, including amounts accrued in accordance with ASC 450, Contingencies, was $920 thousand, $2.0 million, and $1.7 million, for the years ended December 31, 2015, 2014, and 2013, respectively. The total accrued liability related to mortgage repurchase claims was $3.2 million at both December 31, 2015 and 2014.

We may not be able to realize our deferred tax assets in the future and they may be subject to additional valuation allowances, which could adversely affect our operating results and regulatory capital ratios.

As of December 31, 2015, Synovus had $511.9 million in net deferred tax assets, of which $341.1 million was disallowed when calculating regulatory capital. Management assesses the valuation allowance recorded against deferred tax assets at each reporting period. The determination of whether a valuation allowance for deferred tax assets is appropriate is subject to considerable judgment and requires an evaluation of all positive and negative evidence. We had a valuation allowance of $11.7 million at

35

December 31, 2015, which is related to specific state income tax credits that have various expiration dates through the tax year 2018 and are expected to expire before they can be utilized.

The valuation allowance could fluctuate in future periods based on the assessment of the positive and negative evidence. If actual results differ significantly from the current estimates of future taxable income, the valuation allowance may need to be increased. Such an increase to the deferred tax asset valuation allowance could have a material adverse effect on our financial condition and results of operations.

Future changes in the tax laws could significantly impact our income tax expense, deferred tax asset balance, and the amount of taxes payable.  Current proposals to lower the Federal corporate income tax rate would result in a reduction to our deferred tax asset balance upon enactment of the new tax legislation, with a corresponding one-time, non-cash increase in income tax expense.  Such increase in income tax expense could be material to our results of operations. See “Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Income Tax Expense” and "Part II - Item 8. Financial Statements and Supplementary Data - Note 22 - Income Taxes" in this Report for further information.

Issuances or sales of common stock or other equity securities could result in an “ownership change” as defined for U.S. federal income tax purposes. In the event an “ownership change” were to occur, our ability to fully utilize a significant portion of our U.S. federal and state tax net operating losses and certain built-in losses that have not been recognized for tax purposes could be impaired as a result of the operation of Section 382 of the Code.

Our ability to use certain realized NOLs and unrealized built-in losses to offset future taxable income may be significantly limited if we experience an “ownership change” as defined by Section 382 of the Code. An ownership change under Section 382 generally occurs when a change in the aggregate percentage ownership of the stock of the corporation held by “five percent shareholders” increases by more than fifty percentage points over a rolling three-year period. A corporation experiencing an ownership change generally is subject to an annual limitation on its utilization of pre-change losses and certain post-change recognized built-in losses equal to the value of the stock of the corporation immediately before the “ownership change,” multiplied by the long-term tax-exempt rate (subject to certain adjustments). The annual limitation is increased each year to the extent that there is an unused limitation in a prior year. Since U.S. federal net operating losses generally may be carried forward for up to 20 years, the annual limitation also effectively provides a cap on the cumulative amount of pre-change losses and certain post-change recognized built-in losses that may be utilized. Pre-change losses and certain post-change recognized built-in losses in excess of the cap are effectively unable to be used to reduce future taxable income. In some circumstances, issuances or sales of our stock (including any common stock or other equity issuances or debt-for-equity exchanges and certain transactions involving our stock that are outside of our control) could result in an “ownership change” under Section 382.

In April 2010, we adopted a Rights Plan, which was approved by our shareholders in April 2011 at our 2011 annual meeting. In April 2013, our Board extended the Rights Plan to April 26, 2016, with shareholder ratification in April 2014 at our 2014 annual meeting. The Rights Plan provides an economic disincentive for any one person or group acting in concert to become an owner, for relevant tax purposes, of 5% or more of our stock and is intended to protect our NOLs from the potential negative consequence of an ownership change as defined under Section 382 of the Code.

While adoption of the Rights Plan should reduce the likelihood that future transactions in our stock will result in an ownership change, there can be no assurance that the Rights Plan will be effective to deter a shareholder from increasing its ownership interests beyond the limits set by the Rights Plan or that an ownership change will not occur in the future, especially if the Rights Plan is not extended or a new Rights Plan is not adopted when the current Rights Plan terminates. Furthermore, our ability to enter into future transactions, including those requiring the issuance of additional ownership interests, may be impaired if such transactions result in an unanticipated “ownership change” under Section 382. If an “ownership change” under Section 382 were to occur, the value of our net operating losses and a portion of the net unrealized built-in losses will be impaired.

The costs and effects of litigation, investigations or similar matters involving us or other financial institutions or counterparties, or adverse facts and developments related thereto, could materially affect our business, operating results and financial condition.

We may be involved from time to time in a variety of litigation, investigations, inquiries or similar matters arising out of our business, including those described in “Part I - Item 3. Legal Proceedings” and "Part II - Item 8. Financial Statements and Supplementary Data - Note 19 - Legal Proceedings" of this Report. Synovus cannot predict the outcome of these or any other legal matters. We establish reserves for legal claims when payments associated with the claims become probable and the losses can be reasonably estimated. We may still incur legal costs for a matter even if we have not established a reserve. In addition, the actual cost of resolving a legal claim may be substantially higher than any amounts reserved for that matter. For those legal matters where the amounts associated with the claims are not probable and the costs cannot be reasonably estimated, Synovus estimates a range of reasonably possible losses. As of December 31, 2015, Synovus' management currently estimates the aggregate range of reasonably possible losses resulting from our outstanding litigation, including, without limitation, the matters described in this Report is from zero to $15.0 million in excess of the amounts accrued, if any, related to those matters. This estimated aggregate range is based upon information currently available to us, and the actual losses could prove to be higher. As there are further developments in these legal matters, we will reassess these matters and the estimated range of reasonably possible losses

36

may change as a result of this assessment. In addition, in the future, we may need to record additional litigation reserves with respect to these matters. Further, regardless of how these matters proceed, it could divert our management's attention and other resources away from our business.

Our insurance may not cover all claims that may be asserted against it and indemnification rights to which we are entitled may not be honored, and any claims asserted against us, regardless of merit or eventual outcome, may harm our reputation. Should the ultimate judgments or settlements in any litigation or investigation significantly exceed our insurance coverage, they could have a material adverse effect on our business, financial condition and results of operations. In addition, premiums for insurance covering the financial and banking sectors are rising. We may not be able to obtain appropriate types or levels of insurance in the future, nor may we be able to obtain adequate replacement policies with acceptable terms or at historic rates, if at all.

Our stock price is subject to fluctuations, and the value of your investment may decline.

The trading price of our common stock is subject to wide fluctuations. The stock market in general, and the market for the stocks of commercial banks and other financial services companies in particular, has experienced significant price and volume fluctuations that sometimes have been unrelated or disproportionate to the operating performance of those companies. hese broad market and industry factors may seriously harm the market price of our common stock, regardless of our operating performance, and the value of your investment may decline.

Certain shares of our common stock are entitled to ten votes per share on each matter submitted to a vote at a meeting of shareholders.

Although we only have one class of common stock, certain shares of our common stock are entitled to ten votes per share on each matter submitted to a vote at a meeting of shareholders, including common stock that has been beneficially owned continuously by the same shareholder for a period of forty-eight consecutive months before the record date of any meeting of shareholders at which the share is eligible to be voted. Therefore, while a holder of common stock may have an economic interest in us that is identical to or even greater than another shareholder, that other shareholder may be entitled to ten times as many votes per share. As a result, some groups of shareholders will be able to approve strategic transactions or increases in authorized capital stock, among other matters submitted to the shareholders, even over the objections of shareholders, who hold equivalent or greater economic stakes in our company.

Our articles of incorporation, our Rights Plan and certain banking laws and regulations may have an anti-takeover effect.

Provisions of our articles of incorporation, our Rights Plan and certain banking laws and regulations, including regulatory approval requirements, could make it more difficult for a third party to acquire us, even if doing so would be perceived to be beneficial to our shareholders. The combination of these provisions may inhibit a non-negotiated merger or other business combination, which, in turn, could adversely affect the market price of our common stock.

ITEM 2. PROPERTIES

We and our subsidiaries own or lease all of the real property and/or buildings in which we operate our business. All of such buildings are in a good state of repair and are appropriately designed for and are suitable for the purposes for which they are used.

As of December 31, 2015, we and our subsidiaries owned 220 facilities encompassing approximately 2,130,098 square feet and leased from third parties 91 facilities encompassing approximately 927,741 square feet. The owned and leased facilities are primarily comprised of office space from which we conduct our business. The following table provides additional information with respect to our leased facilities:

ITEM 3. LEGAL PROCEEDINGS

Synovus and its subsidiaries are subject to various legal proceedings and claims that arise in the ordinary course of its business. Additionally, in the ordinary course of business, Synovus and its subsidiaries are subject to regulatory examinations, information gathering requests, inquiries and investigations. Synovus, like many other financial institutions, has been the target of numerous legal actions and other proceedings asserting claims for damages and related relief for losses. These actions include claims and counterclaims asserted by individual borrowers related to their loans and allegations of violations of state and federal laws and regulations relating to banking practices, including putative class action matters. In addition to actual damages if Synovus does not prevail in any asserted legal action, credit-related litigation could result in additional write-downs or charge-offs of assets, which could adversely affect Synovus' results of operations during the period in which the write-down or charge-off were to occur.

Based on our current knowledge and advice of counsel, management presently does not believe that the liabilities arising from these legal matters will have a material adverse effect on Synovus' consolidated financial condition, operating results or cash flows. However, it is possible that the ultimate resolution of these legal matters could have a material adverse effect on Synovus' results of operations and financial condition for any particular period. For additional information, see "Part II - Item 8. Financial Statements and Supplementary Data - Note 19 - Legal Proceedings" of this Report, which Note is incorporated in this Item 3 by this reference.

During both 2015 and 2014, Synovus paid dividends of $10.2 million on its Series C Preferred Stock, which was issued in July 2013.

Synovus has historically paid a quarterly cash dividend to the holders of its common stock. Management closely monitors trends and developments in credit quality, liquidity (including dividends from subsidiaries), financial markets and other economic trends, as well as regulatory requirements regarding the payment of dividends, all of which impact Synovus' capital position, and will continue to periodically review dividend levels to determine if they are appropriate in light of these factors and the restrictions on payment of dividends described below.

Under the laws of the State of Georgia, we, as a business corporation, may declare and pay dividends in cash or property unless the payment or declaration would be contrary to restrictions contained in our articles of incorporation, or unless, after payment of the dividend, we would not be able to pay our debts when they become due in the usual course of our business, or our total assets would be less than the sum of our total liabilities. In addition, we are also subject to federal regulatory capital requirements that effectively limit the amount of cash dividends, if any, that we may pay.

Synovus' ability to pay dividends is partially dependent upon dividends and distributions that it receives from Synovus Bank and its non-banking subsidiaries, which are restricted by various regulations administered by federal and state bank regulatory authorities. During 2014, Synovus Bank made upstream cash distributions to the Parent Company totaling $182.0 million including cash dividends of $90.6 million. During 2015, Synovus Bank made upstream cash distributions to the Parent Company totaling $225.0 million including cash dividends of $199.9 million. On February 12, 2016, Synovus Bank paid an upstream cash dividend of $100.0 million to the Parent Company. Synovus' ability to receive dividends from Synovus Bank in future periods will depend on a number of factors, including, without limitation, Synovus Bank's future profits, asset quality, liquidity and overall condition. In addition, GA DBF rules and related statutes contain limitations on payments of dividends by Synovus Bank without the approval of the GA DBF. See "Part I - Item 1. Business - Supervision, Regulation and Other Factors - Dividends" of this Report for further information. Synovus is also subject to contractual restrictions that limit its ability to pay dividends if there is an event of default under such contract. Synovus in the future may become subject to additional supervisory actions and/or enhanced regulation that could have a material negative effect on business, operating flexibility, financial condition, and the value of our common stock and preferred stock.

See “Part I - Item 1. Business - Supervision, Regulation and Other Factors - Dividends," "Part I - Item 1A. Risk factors - We may become subject to supervisory actions and enhanced regulation that could have a material negative effect on our business, reputation, operating flexibility, financial condition and the value of our common stock and preferred stock.” and “Part I - Item 1A. Risk Factors - We may be unable to pay dividends on our common stock and Series C Preferred Stock.” of this Report for additional information regarding dividends on Synovus stock.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Executive Summary

The following financial review provides a discussion of Synovus' financial condition, changes in financial condition, and results of operations as well as a summary of Synovus' critical accounting policies. This section should be read in conjunction with the audited consolidated financial statements and accompanying notes included in Part II Item 8 - Financial Statements and Supplementary Data of this Report.

Overview of 2015 Financial Results

Net income available to common shareholders was $215.8 million, or $1.62 per diluted common share for the year ended December 31, 2015, an increase of 16.7% and 21.9%, respectively, compared to net income available to common shareholders of $185.0 million, or $1.33 per diluted common share for the year ended December 31, 2014.

2015 results reflect continued broad-based improvement in credit quality as the NPA ratio declined below 1.0% to 0.96% at December 31, 2015 from 1.35% at December 31, 2014. Total credit costs (consisting primarily of provision for loan losses and foreclosed real estate expense, net) were $50.7 million in 2015, a $16.0 million or 24.0% decline from 2014. The NPL ratio declined to 0.75% at December 31, 2015 from 0.94% at December 31, 2014. Total non-performing assets were $215.4 million at December 31, 2015, down $71.4 million, or 24.9%, from December 31, 2014. Net charge-offs totaled $27.8 million, or only 0.13% of average loans, in 2015 down from $79.1 million or 0.39% of average loans in 2014. Total past due loans over 90 days were only 0.01% at December 31, 2015, down one basis point from December 31, 2014.

Adjusted pre-tax, pre-credit costs income (which excludes provision for loan losses, other credit costs, litigation contingency/settlement expenses, restructuring charges, loss on early extinguishment of debt, and certain other items) was $414.6 million in 2015, up 4.0% or $16.1 million from 2014. The increase in adjusted pre-tax, pre-credit costs income was driven by a $8.0 million, or 1.0%, increase in net interest income resulting mainly from a 5.6% increase in average loans, net, of $1.14 billion, and a $10.2 million, or 4.0%, increase in adjusted non-interest income, partially offset by a $2.1 million, or 0.3%, increase in adjusted non-interest expense and a decline of 19 basis points in the net interest margin. See "Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Non-GAAP Financial Measures" of this Report for further information.

The net interest margin declined 19 basis points to 3.19% for the year ended December 31, 2015 compared to the prior year. The yield on earning assets declined 19 basis points to 3.64% and the effective cost of funds was unchanged at 0.45%, in each case for the year ended December 31, 2015 and December 31, 2014.

Total loans ended the year at $22.43 billion, a $1.33 billion, or 6.3%, increase from a year ago. The increase was driven by a $448.9 million, or 6.5%, growth in CRE loans, a $523.7 million, or 5.1%, increase in C&I loans, and a $358.6 million, or 9.1%, increase in retail loans.

Total deposits of $23.24 billion at December 31, 2015 increased $1.71 billion, or 7.9%, from a year ago. Average total deposits grew $1.58 billion, or 7.6%, and average core deposits increased $1.60 billion, or 8.2%, from a year ago, driven by an increase in average non-interest bearing deposits and average money market deposits. See "Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Non-GAAP Financial Measures" of this Report for further information.

On December 7, 2015, Synovus issued in a public offering $250 million aggregate principal amount of subordinated debt due in 2025, for aggregate proceeds of $246.6 million, net of debt issuance costs. Also during the fourth quarter of 2015, Synovus repurchased $46.7 million of the 2017 subordinated notes which resulted in a pre-tax loss of $1.5 million.

During 2015, Synovus maintained strong capital levels and returned over $250 million in capital to common shareholders with $199.2 million of common stock repurchases and $55.4 million of common stock dividends. Synovus' share count declined 4.8% from 2014 and book value per common share increased 3.6% to $22.19 at December 31, 2015.

Critical Accounting Policies

The accounting and financial reporting policies of Synovus are in accordance with U.S. GAAP and conform to the accounting and reporting guidelines prescribed by bank regulatory authorities. Synovus has identified certain of its accounting policies as “critical accounting policies,” consisting of those related to the accounting for the allowance for loan losses and determining the fair value of financial instruments. In determining which accounting policies are critical in nature, Synovus has identified the policies that require significant judgment or involve complex estimates. It is management's practice to discuss critical accounting policies with the Board of Directors' Audit Committee on a periodic basis, including the development, selection, implementation and disclosure of the critical accounting policies. The application of these policies has a significant impact on Synovus’ consolidated financial statements. Synovus’ financial results could differ significantly if different judgments or estimates are applied in the application of these policies.

Allowance for Loan Losses

The allowance for loan losses is a significant accounting estimate that is determined through periodic and systematic detailed reviews of the Company’s loan portfolio. These reviews are performed to assess the probable incurred losses within the portfolio and to ensure consistency between fluctuations in the allowance and both credit events within the portfolio and prevailing credit trends. The economic and business climate in any given industry or market is difficult to gauge and can change rapidly, and the effects of those changes can vary by borrower. Significant judgments and estimates are necessary in the determination of the allowance for loan losses. Significant judgments include, among others, loan risk ratings and classifications, the determination and measurement of impaired loans, the timing of loan charge-offs, the probability of loan defaults, the net loss exposure in the event of loan defaults, the loss emergence period, qualitative loss factors, management’s plans, if any, for disposition of certain loans, as well as other qualitative considerations. In determining the allowance for loan losses, management makes numerous assumptions, estimates, and assessments, which are inherently subjective. The use of different estimates or assumptions could have a significant impact on the provision for loan losses, allowance for loan losses, non-performing loans, loan charge-offs, financial condition and results of operations.

Dual Risk Rating Implementation

Synovus began implementation of a Dual Risk Rating allowance for loan losses methodology (DRR methodology) for certain components of its commercial and industrial loan portfolio during 2013. The DRR methodology includes sixteen probabilities of default categories and nine categories for estimating losses given an event of default. The result is an expected loss rate established for each borrower. The DRR methodology is generally considered in the banking industry to be a more refined estimate of the inherent risk of loss. The 2013 DRR methodology implementation was applied to approximately $2.4 billion of the total commercial and industrial loan portfolio. Implementation of the DRR methodology resulted in a reduction to the provision for loan losses and the allowance for loan losses of approximately $2.5 million for 2013. During 2014, the DRR implementation was expanded to certain components of the investment properties commercial real estate portfolio totaling approximately $2.5 billion. This implementation resulted in an increase to the provision for loan losses and the allowance for loan losses of approximately $1.8 million for the year ended December 31, 2014. During 2015, the DRR methodology was expanded to additional components of the investment properties commercial real estate portfolio totaling approximately $155 million, which resulted in a decrease to the provision for loan losses and the allowance for loan losses of approximately $250 thousand for the year ended December 31, 2015.

At December 31, 2015, the DRR methodology is utilized to calculate the allowance for loan losses for36.7% of the commercial loan portfolio and 29.8% of the total loan portfolio. Management currently expects to implement the DRR methodology for additional components of the commercial loan portfolio over the next few years. The implementation is expected to be in multiple phases, with each component determined based primarily on loan type and size. The timing of future implementations will depend upon completion of applicable data analysis and model assessment. Once full implementation is completed, management estimates that the DRR methodology will be utilized to calculate the allowance for loan losses on commercial loans amounting to approximately 35% of the total loan portfolio.

Fair Value Measurements

Synovus evaluates assets, liabilities and other financial instruments that are either required or elected to be carried, reported, or disclosed at fair value, and determines the valuation of these instruments in accordance with FASB ASC Topic 820, Fair Value Measurements, which defines fair value as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Synovus assesses the fair value measurements of each instrument on a periodic basis, but no less than quarterly.

Synovus determines the fair value of its financial instruments based on the fair value hierarchy established under ASC 820, which provides a three-level framework for determining the appropriate fair value for a particular asset or liability. Fair value may be based on quoted market prices for identical assets or liabilities traded in active markets (Level 1 valuations). If market prices are not available, quoted prices for similar instruments in active markets, quoted prices in markets that are not active or model-

46

based valuation techniques for which all significant assumptions are derived principally from or corroborated by observable market data are used (Level 2 valuations). Where observable market data is not available, the valuation is generated using pricing models, discounted cash flow models and similar techniques, and may also include the use of market prices of financial instruments that are not directly comparable to the subject instrument. These methods of valuation may result in a significant portion of the fair value being derived from unobservable assumptions that reflect Synovus’ own estimates for assumptions that market participants would use in pricing the financial instrument (Level 3 valuations). The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the financial instrument’s fair value measurement in its entirety.

Synovus selects the most appropriate technique for determining the fair value of the asset or liability. The degree of management judgment involved in determining fair value is dependent upon the availability of quoted prices or observable market data. There is minimal subjectivity involved in measuring the fair value of financial instruments based on quoted market prices; however, when quoted prices and observable market data are not available, Synovus would use a valuation technique requiring more management judgment to estimate the appropriate fair value.

Fair value is measured either on a recurring basis, in which the fair value is the primary measure of accounting, or on a non-recurring basis, to measure items for potential impairment, or for disclosure purposes.

Assets, liabilities and other financial instruments classified as Level 3 in the fair value hierarchy are generally less liquid and estimating their value requires inputs that are unobservable and require the application of significant judgment on behalf of management in order to determine the appropriate fair value of each of these instruments. As of December 31, 2015, Synovus reported $28.9 million of assets (or 0.1% of total assets) classified as Level 3, of which $27.1 million consisted of private equity investments. Also, as of December 31, 2015, Synovus reported $1.4 million of liabilities (or 0.01% of total liabilities) classified as Level 3.

See "Part II - Item 8. Financial Statements and Supplementary Data - Note 14 - Fair Value Accounting" of this Report for further discussion of Synovus' use of the various fair value methodologies and the types of assets and liabilities in which fair value accounting is applied.

DISCUSSION OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Investment Securities Available for Sale

The investment securities portfolio consists principally of debt securities classified as available for sale. Investment securities available for sale provide Synovus with a source of liquidity and a relatively stable source of income. The investment securities portfolio also provides management with a tool to balance the interest rate risk of its loan and deposit portfolios. See Table 13 for maturity and average yield information of the investment securities available for sale portfolio.

The investment strategy focuses on the use of the investment securities portfolio to generate interest income and to assist in the management of interest rate risk. Synovus moderately increased portfolio duration during 2015 while the average balance of the portfolio increased at a pace similar to overall earning asset growth. The average duration of Synovus’ investment securities portfolio was 2.9 years at December 31, 2015 compared to 2.7 years at December 31, 2014.

Synovus also utilizes a significant portion of its investment portfolio to secure certain deposits and other liabilities requiring collateralization. At December 31, 2015, $2.43 billion of these investment securities were pledged to secure certain deposits and securities sold under repurchase agreements as required by law and contractual agreements. The investment securities are primarily mortgage-backed securities issued by U.S. government agencies and GSEs, both of which have a high degree of liquidity and limited credit risk. A mortgage-backed security depends on the underlying pool of mortgage loans to provide a cash flow pass-through of principal and interest. At December 31, 2015, all of the collateralized mortgage obligations and mortgage-backed pass-through securities held by Synovus were issued or backed by federal agencies or GSEs.

As of December 31, 2015 and 2014, the estimated fair value of investment securities available for sale as a percentage of their amortized cost was 99.8% and 100.7%, respectively. The investment securities available for sale portfolio had gross unrealized gains of $19.3 million and gross unrealized losses of $27.3 million, for a net unrealized loss of $8.0 million as of December 31, 2015. The investment securities available for sale portfolio had gross unrealized gains of $32.9 million and gross unrealized losses of $12.4 million, for a net unrealized gain of $20.5 million as of December 31, 2014. Shareholders’ equity included net unrealized losses of $18.2 million and net unrealized losses of $713 thousand on the available for sale portfolio as of December 31, 2015 and 2014, respectively.

The average balance of investment securities available for sale increased to $3.26 billion at December 31, 2015 from $3.09 billion at December 31, 2014. Synovus earned a taxable-equivalent rate of 1.82% and 1.88% for 2015 and 2014, respectively, on

47

its investment securities available for sale portfolio. For the years ended December 31, 2015 and 2014, investment securities available for sale represented 12.55% and 12.71%, respectively, of interest earning assets.

The following table shows investment securities available for sale by type as of December 31, 2015 and 2014.

nm - not meaningful

Total loans ended the year at $22.43 billion, a $1.33 billion or 6.3% increase from a year ago. The increase was driven by well balanced growth across the entire loan portfolio - a $448.9 million or 6.5% increase in commercial real estate loans, a $523.7 million or 5.1% increase in commercial and industrial loans, and a $358.6 million or 9.1% increase in retail loans. Annual loan growth for 2016 is currently expected to be in the mid single-digits.

Commercial Loans

The commercial loan portfolio consists of commercial and industrial loans and commercial real estate loans. Total commercial loans at December 31, 2015 were $18.17 billion, or 80.9% of the total loan portfolio, and grew $972.6 million or 5.7% from December 31, 2014.

The Corporate Banking Group provides lending solutions to larger corporate clients and includes specialty commercial loan units such as loan syndications, corporate real estate, senior housing, middle market, equipment finance, and healthcare banking. These units partner with Synovus' local bankers to build relationships across the five-state footprint, as well as selected other areas in the southeastern and southwestern United States. To date, loan syndications consist primarily of loans where Synovus is participating in the credit. Senior housing loans are typically extended to borrowers primarily in the assisted living, independent living, or memory care facilities sectors. Synovus has continued to develop its middle market lending program by enhancing its focus on this program and reallocating lending resources while sustaining momentum from investments made in other specialty lines such as healthcare banking. The Corporate Banking Group also originates direct loans to well-capitalized public companies and larger private companies that operate predominantly in the five-state footprint and other Southeastern states.

At December 31, 2015 and 2014, Synovus had 24 and 25 commercial loan relationships with total commitments of $50 million or more (including amounts funded), respectively. The average funded balance of these relationships at December 31, 2015 and 2014 was approximately $35 million and $36 million, respectively.

Commercial and Industrial (C&I) Loans

Total commercial and industrial loans at December 31, 2015 were $10.79 billion, or 48.1% of the total loan portfolio, compared to $10.27 billion, or 48.7% of the total loan portfolio at December 31, 2014, an increase of $523.7 million, or 5.1%, from 2014. The commercial and industrial loan portfolio represents the largest category of Synovus' total loan portfolio and is currently concentrated on small to middle market commercial and industrial lending disbursed throughout a diverse group of industries primarily in the Southeast. The industries that primarily contributed to the C&I loan growth during 2015 included health care and social assistance,

50

transportation and warehousing, retail trade, finance and insurance, wholesale trade, and accommodation and food services. For more detailed information on the C&I portfolio by industry at December 31, 2015 and 2014 see the table below, Commercial and Industrial Loans by Industry.

lending expertise in key strategic markets as well as offer enhanced products and services to its commercial and industrial clients. Complementing this investment in C&I growth, management continues to focus on streamlining and enhancing Synovus' existing product lines, especially for traditional retail, small business, and professional services customers. Synovus has increased its focus in areas such as SBA/Government Guaranteed Lending, which is an extension of our relationship-based banking approach. SBA/Government Guaranteed Lending generated a 65% increase in loan production during 2015, driven by talent acquisition as well as new product offerings. A similar level of production growth is expected in 2016.

At December 31, 2015, $6.47 billion, or 60.0% of the total commercial and industrial loans represented loans for the purpose of financing commercial, financial, and agricultural business activities compared to $6.18 billion or 60.2% of the total commercial and industrial loans at December 31, 2014 . The primary source of repayment on these loans is revenue generated from products or services offered by the business or organization. The secondary source of repayment is the collateral, which consists primarily of equipment, inventory, accounts receivable, time deposits, and other business assets.

At December 31, 2015, $4.32 billion, or 40.0% of the total commercial and industrial loans represented loans for the purpose of financing owner-occupied properties compared to $4.09 billion or 39.8% of the total commercial and industrial loans at December 31, 2014. The primary source of repayment on these loans is revenue generated from products or services offered by the business or organization. The secondary source of repayment on these loans is the real estate. These loans are predominantly secured by owner-occupied and other real estate, and to a lesser extent, other types of collateral.

Commercial Real Estate Loans

Total commercial real estate loans, consisting of investment properties, 1-4 family properties, and land acquisition loans and representing 32.8% of the total loan portfolio at December 31, 2015, were $7.38 billion, an increase of $448.9 million, or 6.5%, from December 31, 2014. The increase was primarily the result of growth in investment properties loans partially offset by reductions in land acquisition loans and 1-4 family properties loans.

51

Investment Properties Loans

Total investment properties loans as of December 31, 2015 were $5.75 billion, or 78.0% of the total commercial real estate loan portfolio, and 25.6% of the total loan portfolio, compared to $5.21 billion, or 75.2% of the total commercial real estate loan portfolio, and 24.7% of the total loan portfolio at December 31, 2014. Total investment properties increased $545.0 million or 10.5% during 2015 primarily due to strong growth in the office buildings and multi-family properties categories. Substantially all of the growth in office buildings loans was non-construction related. Investment properties loans consist of construction and mortgage loans for income producing properties and are primarily made to finance multi-family properties, hotels, office buildings, shopping centers, warehouses and other commercial development properties.

The following table shows the principal categories of the investment properties loan portfolio at December 31, 2015 and 2014.

*Loan balance in each category expressed as a percentage of total investment properties loans.

1-4 Family Properties Loans

At December 31, 2015, 1-4 family properties loans declined to $1.11 billion, or 15.0% of the total commercial real estate portfolio, and 4.9% of the total loan portfolio, compared to $1.13 billion, or 16.4% of the total commercial real estate portfolio, and 5.3% of the total loan portfolio at December 31, 2014 primarily due to limited originations of new loans and principal reductions. 1-4 family properties loans include construction loans to homebuilders, commercial mortgage loans to real estate investors, and residential development loans to developers and are almost always secured by the underlying property being financed by such loans. Construction and residential development loans are primarily interest-only loans and typically carry maturities of three years or less, and 1-4 family rental properties carry maturities of three to five years, with amortization periods of up to fifteen to twenty years.

Land Acquisition Loans

Land acquisition loans were $514.0 million at December 31, 2015, or 7.0% of the total commercial real estate portfolio and 2.3% of the total loan portfolio. Land acquisition loans declined 12.3% from December 31, 2014, primarily due to very limited originations of new loans, principal reductions and continued resolution of selected distressed loans. Land acquisition loans are secured by land held for future development, typically in excess of one year. They have short-term maturities and are typically unamortized. These properties are substantially within the Synovus footprint and generally carry personal guarantees from the principals. They are underwritten based on the loan to value of the collateral and the capacity of the guarantor(s).

52

Retail Loans

Total retail loans as of December 31, 2015 were $4.29 billion, or 19.1% of the total loan portfolio compared to $3.93 billion, or 18.5% of the total loan portfolio at December 31, 2014. Total retail loans increased by $358.6 million, or 9.1%, from December 31, 2014 due primarily to initiatives to grow this portion of the loan portfolio. The retail loan portfolio consists of a wide variety of loan products offered through Synovus' banking network, including first and second residential mortgages, home equity lines, credit card loans, automobile loans, and other retail loans. These various types of secured and unsecured retail loans are marketed to qualifying existing clients and to other creditworthy candidates in Synovus' market area. The majority of Synovus' retail loans are consumer mortgages and home equity lines secured by first and second liens on residential real estate primarily located in the markets served by Synovus. Consumer mortgages increased $244.6 million or 14.4% from 2014 to $1.94 billion primarily due to enhanced origination efforts to potential Private Client Services customers. Credit card loans totaled $240.9 million at December 31, 2015 and $253.6 million at December 31, 2014, including $52.2 million and $55.3 million of commercial credit card loans at December 31, 2015 and 2014, respectively. These commercial credit card loans relate to Synovus' commercial customers who utilize corporate credit cards for various business activities. Other retail loans increased $120.9 million or 40.0% to $423.3 million at December 31, 2015, primarily due to beginning a point of sale lending partnership near the end of the third quarter of 2015. Additional similar retail lending strategies are being considered and would complement our overall growth plan. It is currently expected that these strategies would not comprise more than 2-3% of the total loan portfolio.

Risk levels 1-6 (descending) are assigned to retail loans based upon a risk score matrix. The retail loan portfolio is sent to a consumer credit reporting agency for a refresh of customers' credit scores at least annually to determine ongoing consistency or negative migration in the quality of the portfolio. As part of the refresh most recently completed as of December 31, 2015, revolving lines of credit were reviewed for a material change in financial circumstances and subsequently suspended for further advances when warranted. FICO scores within the retail residential real estate portfolio have generally remained stable over the last several years.

Higher-risk consumer loans as defined by the FDIC are consumer loans (excluding consumer loans defined as nontraditional mortgage loans) where, as of the origination date or, if the loan has been refinanced, as of the refinance date, the probability of default within two years is greater than 20%, as determined using a defined historical stress period. These loans are not a part of Synovus' retail lending strategy, and Synovus does not currently develop or offer specific sub-prime, alt-A, no documentation or stated income retail residential real estate loan products. Synovus estimates that, as of December 31, 2015, it has $116.2 million of higher-risk consumer loans (2.7% of said portfolio and 0.5% of the total loan portfolio) compared to $134.9 million as of December 31, 2014. Included in these amounts are $13.4 million and $15.9 million, respectively, of accruing TDRs as of December 31, 2015 and December 31, 2014. Synovus makes retail lending decisions based upon a number of key credit risk determinants including FICO scores, loan-to-value, and debt-to-income ratios.

At December 31, 2015 and December 31, 2014, weighted average FICO scores within the retail residential real estate portfolio were 769 and 766 (HELOCs), respectively, and 759 and 757 (Consumer Mortgages), respectively. Total past dues within the retail residential real estate portfolio as of December 31, 2015 were 0.35% (HELOCs) and 0.45% (Consumer Mortgages) compared to 0.46% (HELOCs) and 0.75% (Consumer Mortgages) at December 31, 2014. The net charge-off ratios for the year ended December 31, 2015 were 0.18% (HELOCs) and 0.31% (Consumer Mortgages) compared to 0.33% (HELOCs) and 0.28% (Consumer Mortgages) for the year ended December 31, 2014.

Deposits

Deposits provide the most significant funding source for interest earning assets. Total deposits were $23.24 billion at December 31, 2015, an increase of $1.71 billion, or 7.9%, compared to year-end 2014. Non-interest bearing deposits totaled $6.73 billion, at December 31, 2015, an increase of $504.5 million, or 8.1%, from December 31, 2014.

The following table shows the relative composition of average deposits for 2015 and 2014. See Table 21 for additional information on average deposits including average rates paid in 2015, 2014, and 2013.

Total average deposits increased $1.58 billion, or 7.6%, to $22.55 billion in 2015 from $20.97 billion in 2014. Average core deposits were up $1.60 billion, or 8.2%, from 2014 and average non-interest bearing demand deposits as a percentage of total average deposits were 28.8% for 2015 compared to 27.7% for 2014. Average core deposits excluding average state, county, and municipal (SCM) deposits grew $1.58 billion, or 9.1%, from the previous year. The increase in deposits was largely due to growth in money market and non-interest bearing demand deposits. See "Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Non-GAAP Financial Measures” of this Report for further information.

Average brokered deposits represented 6.3% of Synovus' total average deposits for 2015 compared to 6.8% for 2014.

Time deposits of $100,000 and greater at December 31, 2015 and 2014 were $2.77 billion and $3.31 billion, respectively, and included brokered time deposits of $759.5 million and $1.46 billion, respectively. See Table 19 for the maturity distribution of time deposits of $100,000 or more. These larger deposits represented 11.9% and 15.4% of total deposits at December 31, 2015 and 2014, respectively, and included brokered time deposits which represented 3.3% and 6.8% of total deposits at December 31, 2015 and 2014, respectively.

Net Interest Income

The following table summarizes the components of net interest income for the years ended December 31, 2015, 2014 and 2013, including the tax-equivalent adjustment that is required in making yields on tax-exempt loans and investment securities comparable to taxable loans and investment securities. The taxable-equivalent adjustment is based on a 35% federal income tax rate.

Table 20 - Net Interest Income
	Years Ended December 31,
(in thousands)	2015		2014	2013
Interest income	$	945,962	928,692	929,014
Taxable-equivalent adjustment	1,304		1,678	2,184
Interest income, taxable-equivalent	947,266		930,370	931,198
Interest expense	118,644		109,408	118,822
Net interest income, taxable-equivalent	$	828,622	820,962	812,376

Net interest income (interest income less interest expense) is the largest component of total revenues, representing earnings from the primary business of gathering funds from customer deposits and other sources, and investing those funds primarily in loans and investment securities. Synovus’ long-term objective is to manage those assets and liabilities to maximize net interest income while balancing interest rate, credit, liquidity, and capital risks.

Net interest income is presented in this discussion on a tax-equivalent basis so that the income from assets exempt from federal income taxes is adjusted based on a statutory marginal federal tax rate of 35% in all years (see Table 20 above). The net interest margin is defined as taxable-equivalent net interest income divided by average total interest earning assets and provides an indication of the efficiency of the earnings from balance sheet activities. The net interest margin is affected by changes in the spread between interest earning asset yields and interest bearing liability costs (spread rate), and by the percentage of interest earning assets funded by non-interest bearing funding sources.

Net interest income for 2015 was $827.3 million, up $8.0 million, or 1.0%, from 2014. On a taxable-equivalent basis, net interest income increased $7.7 million, or 0.9%, from 2014. During 2015, average earning assets increased $1.69 billion, or 7.0%, primarily as a result of an increase in net loans and investment securities balances.

Net interest income for 2014 was $819.3 million, up $9.1 million, or 1.1%, from 2013. On a taxable-equivalent basis, net interest income increased $8.6 million, or 1.1%, from 2013. During 2014, average earning assets increased $391.0 million, or 1.6%, primarily as a result of an increase in net loans.

Net Interest Margin

The net interest margin was 3.19% for 2015, a decrease of 19 basis points from 2014. The yield on earning assets decreased 19 basis points to 3.64% and the effective cost of funds was unchanged at 0.45%. The effective cost of funds includes non-interest bearing funding sources primarily consisting of demand deposits.

The primary components of the yield on interest earning assets are loan yields, yields on investment securities, and the yield on balances held with the Federal Reserve Bank. The primary factors negatively impacting earning asset yields were a 16 basis point decline in loan yields and a 6 basis point decline in taxable investment securities yields. Loan yield decreases were primarily driven by downward repricing of maturing and prepaid loans as well a continued low level of market rates on newly originated loans. The decline in taxable investment securities yields was due to a higher level of purchased premium amortization.

The primary factors impacting the effective cost of funds during 2015 were an 11 basis point increase in the cost of time deposits and a 4 basis point increase in the cost of money market deposits. These increases were offset by a higher level of non-interest bearing funding.

The net interest margin is expected to increase to approximately 3.25% in the first quarter of 2016 from 3.19% for the year 2015. If there are no further rate increases in 2016, the net interest margin could experience modest pressure in the second half of the year. Due to our asset sensitive balance sheet position, a 25 basis point increase in the fed funds rate in June would allow the net interest margin to remain at the 3.25% level for the year with some volatility within the quarters.

The net interest margin was 3.38% for 2014, a decrease of 2 basis points from 2013. The yield on earning assets decreased 6 basis points to 3.83% and the effective cost of funds decreased 4 basis points to 0.45%. The effective cost of funds includes non-interest bearing funding sources primarily consisting of demand deposits.

56

During 2014, loan yields decreased 22 basis points to 4.29%. Loan yield decreases were primarily driven by downward repricing of maturing and prepaid loans as well as a continued low level of market rates on newly originated loans. Factors positively impacting earning asset yields included a 17 basis point increase in taxable investment securities yields primarily due to a lower level of purchased premium amortization. A reduction in lower yielding interest bearing funds at the Federal Reserve Bank also positively impacted earning asset yields.

The primary factors contributing to the 4 basis point decrease in the effective cost of funds during 2014 were a 45 basis point decrease in the cost of long-term debt and a 13 basis point decrease in the cost of time deposits. The decrease in the cost of long term debt is primarily due to the addition of new lower cost debt instruments. The decline in the cost of time deposits was driven by the maturity of older, higher cost deposits which were replaced at current lower cost levels.

Non-interest Income

Non-interest income for the year ended December 31, 2015 was $267.9 million, up $5.8 million, or 2.2%, compared to 2014. Adjusted non-interest income, which excludes net investment securities gains and the prior year net gain of $5.8 million from the Memphis transaction, increased $10.2 million or 4.0% compared to 2014. The increase over prior year was driven primarily by an increase in mortgage banking income. Additionally, all non-interest income categories (except for other non-interest income) reflect growth over the prior year. See "Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Non-GAAP Financial Measures" of this Report for applicable reconciliation.

The following table shows the principal components of non-interest income.

Principal Components of Non-interest Income

Service charges on deposit accounts were $80.1 million in 2015, an increase of $1.2 million, or 1.6%, from the previous year, and $78.9 million in 2014, an increase of 1.4% from 2013. Service charges on deposit accounts consist of NSF fees, account analysis fees, and all other service charges. NSF fees were $37.3 million in 2015, an increase of $1.2 million, or 3.4% from 2014, due primarily to an increase in overdraft service utilization rates and higher opt-in rates under Regulation E (Regulation E limits the ability of a financial institution to assess an overdraft fee for paying automated teller machine and debit card transactions that overdraw a customer's account unless the customer affirmatively consents, or opts-in, to the institution's payment of overdrafts for these transactions). Account analysis fees were $23.3 million in 2015, up $375 thousand, or 1.6%, compared to 2014 largely due to fee increases to align more closely with market rates. All other service charges on deposit accounts, which consist primarily of monthly fees on retail demand deposit and saving accounts, were $19.6 million for 2015, a decrease of $336 thousand, or 1.7%, compared to 2014 with more retail customers meeting requirements to qualify for fee waivers on checking products.

Fiduciary and asset management fees are derived from providing estate administration, employee benefit plan administration, personal trust, corporate trust, corporate bond, investment management and financial planning services. Fiduciary and asset management fees were $45.9 million in 2015, an increase of $702 thousand, or 1.6%, from 2014, due to new talent acquisition in strategic markets and an increase in assets under management of 2.5%. Fiduciary and asset management fees were $45.2 million in 2014, an increase of 4.1% from 2013, due to an increase in assets under management of 7.4%.

At December 31, 2015, the market value of assets under management was approximately $10.8 billion, an increase of 2.5% from 2014, and $10.6 billion at December 31, 2014, an increase of 7.4% from 2013. Reported AUM include approximately $240 million and $274 million at December 31, 2015 and 2014, respectively, of assets managed for certain Synovus employee retirement plans. AUM consist of all assets where Synovus has investment authority. Assets under advisement were approximately $3.2 billion and $3.6 billion at December 31, 2015 and 2014, respectively. Assets under advisement consist of non-managed assets as well as non-custody assets where Synovus earns a consulting fee. Assets under advisement at December 31, 2015 declined 11.4% from 2014 following an increase of 39.2% in 2014 from 2013. Total assets under management and advisement were approximately $14.0 billion at December 31, 2015 compared to approximately $14.2 billion at December 31, 2014. Many of the fiduciary and asset management fee charges are based on asset values, and changes in these values throughout the year directly impact fees earned.

Brokerage revenue was $27.9 million in 2015, a $767 thousand, or 2.8%, increase from 2014, and $27.1 million in 2014, a $450 thousand, or 1.6%, decline from 2013. Brokerage revenue consists primarily of brokerage commissions. Brokerage assets were $4.90 billion and $4.78 billion as of December 31, 2015 and 2014, respectively.

Mortgage banking income increased $5.7 million, or 31.3%, for the year ended December 31, 2015 compared to 2014 due primarily to an increase in mortgage production which was driven by the rate environment, talent acquisitions, investments in key markets, and enhanced product offerings. Mortgage banking income decreased $4.1 million, or 18.4%, during 2014 compared to 2013 primarily from a decrease in mortgage production with a decline in refinancing volume that began in the third quarter of 2013.

Bankcard fees increased $241 thousand, or 0.7%, for the year ended December 31, 2015 compared to 2014. Bankcard fees consist primarily of credit card interchange fees and debit card interchange fees. Debit card interchange fees were $16.6 million, up $254 thousand, or 1.6%, for the year ended December 31, 2015, compared to 2014. Credit card interchange fees were $23.0 million, up $359 thousand, or 1.6%, for the year ended December 31, 2015 compared to 2014. Bankcard fees increased $2.3 million, or 7.5%, for the year ended December 31, 2014 compared to 2013 primarily due to an increase in transaction volume.

Other fee income includes fees for letters of credit and unused lines of credit, safe deposit box fees, access fees for ATM use, customer swap dealer fees, and other service charges. Other fee income increased $2.0 million, or 10.7%, for the year ended December 31, 2015 compared to 2014 due primarily to an increase in customer swap dealer fees. Other fee income declined $3.4 million, or 15.2%, for 2014 compared to 2013 largely due to a decline in customer swap dealer fees.

The 2014 gain on sale of Memphis branches consists of a gain, net of associated costs, from the sale of certain loans, premises, deposits, and other assets and liabilities of the Memphis, Tennessee operations of Trust One Bank, a division of Synovus Bank. Please see "Part II - Item 8. Financial Statements and Supplementary Data - Note 2 - Sale of Branches" of this Report for further explanation of this transaction.

The main components of other non-interest income are income from company-owned life insurance policies, gains from sales of SBA/government guaranteed loans, insurance commissions, card sponsorship fees, and other miscellaneous items. Other non-interest income declined $570 thousand, or 1.7%, for the year ended December 31, 2015 compared to 2014. Other non-interest income for 2014 included a $3.1 million gain from the sale of a branch property. Other non-interest income increased $4.6 million, or 15.8%, for the year ended December 31, 2014 compared to 2013.

Non-interest Expense

Non-interest expense for 2015 was $717.7 million, down $27.3 million, or 3.7%, from 2014, and $745.0 million in 2014, an increase of $3.5 million, or 0.5%, compared to 2013. Adjusted non-interest expense, which excludes Visa indemnification charges, restructuring charges, other credit costs, loss on early extinguishment of debt, and litigation contingency/settlement expenses, was $677.9 million in 2015, an increase of $2.1 million, or 0.3%, from 2014, and $675.7 million in 2014, an increase of $5.2 million, or 0.8%, from 2013. The increase in adjusted non-interest expense during 2015 was due primarily to an increase in salaries and other personnel expense and was largely offset by declines in FDIC insurance expense and advertising expense. The increase in adjusted non-interest expense during 2014 was due largely to planned investments in advertising. Synovus expects the 2016 adjusted non-interest expense percentage increase to be in the low single-digits. See "Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Non-GAAP Financial Measures" of this Report for applicable reconciliation.

The following table summarizes this data for the years ended December 31, 2015, 2014, and 2013.

2015 vs. 2014

Salaries and other personnel expense increased $9.0 million, or 2.4%, in 2015 compared to 2014 due primarily to higher production-driven incentives and annual merit increases. These increases were partially offset by the decrease in salaries and other personnel expense resulting from the decline of 59, or 1.3%, in total headcount at December 31, 2015 compared to December 31, 2014. The decline in headcount was driven primarily by the elimination of positions during 2014 in connection with branch closings, further refinement of our branch staffing model, and other efficiency initiatives.

Net occupancy and equipment expense increased $1.7 million, or 1.6%, during 2015 and included a $1.1 million charge for lease exit costs. Synovus continues to invest in technology and rationalize its branch network which consist of 257 branches at December 31, 2015. As of December 31, 2015, 15.4% of all retail deposits were performed through a non-branch channel (ATM or mobile capture). This transaction migration has contributed to an overall 8.3% decrease in teller staffing compared to a year ago and also supported the reduction of 13 branches in the fourth quarter of 2014. During the second quarter of 2015, Synovus relocated a branch and opened its first new branch prototype in Nashville with a second opening in Sarasota during the fourth quarter of 2015 and a third opening in Jacksonville during early 2016. These branches are smaller in size, reduce barriers between Synovus' customers and bankers, and come equipped with more self-serve and convenient banker-assisted technology.

Third-party processing expense includes all third-party core operating system and processing charges. Third-party processing expense increased $2.8 million, or 7.0%, compared to 2014 driven by investments in technology.

FDIC insurance costs and other regulatory fees declined $6.4 million, or 19.1%, in 2015 compared to 2014 primarily due to significant improvement in credit metrics included in the FDIC assessment scorecard with declines of 24.9% and 35.7% in NPAs and accruing TDRs, respectively.

Advertising expense was $15.5 million in 2015 compared to $24.0 million in 2014. During 2015, we paused on broad-based brand awareness advertising spend while we conducted customer research, focusing instead on targeted retail campaigns and

61

capability advertising. This resulted in a significant reduction in advertising costs compared to 2014. We expect spending levels to moderately increase in 2016 as we resume brand awareness activities in select high growth markets.

Foreclosed real estate costs declined $2.5 million, or 9.9%, to $22.8 million in 2015. The decline was largely a result of lower levels of losses and write-downs due to declines in fair value of ORE, as well as lower inventory due to a reduction in the level of foreclosures.

Other operating expenses for 2015 included $5.1 million in litigation contingency/settlement expenses, and other operating expenses for 2014 included $12.8 million in litigation settlement expenses. Please refer to "Part II - Item 8. Financial Statements and Supplementary Data - Note 19 - Legal Proceedings" of this Report for a more detailed discussion of legal proceedings and expenses related thereto.

2014 vs. 2013

Total employees were 4,511 at December 31, 2014, a decline of 185, or 3.9%, from 4,696 at December 31, 2013. The year-over-year decline included the elimination of approximately 300 positions in connection with branch closings, further refinement of our branch staffing model, as well as other efficiency initiatives, partially offset by workforce additions in Corporate Banking, information technology, and centralized customer care centers. Salaries and other personnel expenses increased $3.8 million, or 1.0%, during 2014 driven by higher levels of production incentives and other variable compensation.

Net occupancy and equipment expense increased $2.5 million, or 2.4%, during 2014 driven by technology investments, including the rollout of almost 200 new full-service ATMs during the year. These additional costs were partially offset by savings realized through Synovus' continued rationalization of its branch network and consolidation of other business facilities. Synovus closed 16 branches during 2014 and sold 4 in the Memphis transaction reducing total branch count at December 31, 2014 to 258.

FDIC insurance costs and other regulatory fees increased $1.3 million, or 3.9%, in 2014 compared to 2013 due to the phase-out from the earnings component measure of the deferred tax asset recapture of $637.5 million recorded in the fourth quarter of 2012 and an increase in the 2014 assessment base driven by loan growth.

Professional fees declined $12.3 million, or 31.8%, in 2014 compared to 2013. The decline in professional fees during 2014 was driven by a decrease in attorney fees and included the benefit of a $2.6 million net insurance recovery for incurred legal fees related to litigation.

Advertising expense increased $15.1 million, or 167.9%, in 2014 compared to 2013 due to a 2014 advertising campaign, highlighted by our "bank of here" campaign, that included brand and capability awareness in key markets throughout Synovus' footprint.

Foreclosed real estate costs declined $8.5 million, or 25.2%, to $25.3 million in 2014. The decline was largely a result of lower levels of write-downs due to declines in fair value of ORE, as well as lower inventory due to a reduction in the level of foreclosures.

Visa indemnification charges were $3.0 million in 2014, an increase of $1.4 million compared to 2013 due to additional funding of the Visa litigation escrow account as allocated under the Covered Litigation.

Restructuring charges for the year ended December 31, 2014 of $20.6 million related primarily to expense savings initiatives that were approved during 2014. The 2014 expense savings initiatives provided annualized cost savings of $30 million. The initiatives included the consolidation or closing of certain branch locations as well as workforce reductions.   Asset impairment and lease termination charges for the year ended December 31, 2014 consisted primarily of charges related to the closure of 13 branches during the fourth quarter of 2014.   Severance charges for the year ended December 31, 2014 consisted of estimated involuntary termination benefits for targeted staff reductions identified during 2014. These termination benefits were provided under an ongoing benefit arrangement as defined in ASC 712, Compensation-Nonretirement Postemployment Benefits; accordingly, the charges were recorded pursuant to the liability recognition criteria of ASC 712.   Additionally, substantially all of the professional fees and other charges for the year ended December 31, 2014 consisted of professional fees incurred in connection with an organizational restructuring implemented during 2014.

Restructuring charges for the year ended December 31, 2013 related primarily to expense savings initiatives approved during 2013 which consisted primarily of the consolidation or closing of certain branch locations as well as workforce reductions. The involuntary termination benefits relating to these workforce reductions were provided under a one-time benefit arrangement as defined in ASC 420, Exit or Disposal Costs or Obligations; accordingly, the charges were recorded pursuant to the liability recognition criteria of ASC 420. For further explanation of restructuring charges, see "Part II - Item 8. Financial Statements and Supplementary Data - Note 3 - Restructuring Charges" of this Report.

The decline in other operating expenses of $10.3 million in 2014 from 2013 was primarily due to declines in credit-related expenses including property taxes and appraisal costs on non-performing loans and commitment reserve expense, as well as declines in most other expense categories. Other operating expenses for 2014 included $12.8 million in litigation settlement

62

expenses and for 2013 included $10.0 million in litigation loss contingency accruals. Please refer to "Part II - Item 8. Financial Statements and Supplementary Data - Note 19 - Legal Proceedings" of this Report for a more detailed discussion of legal proceedings and expenses related thereto.

Income Taxes

Income tax expense was $132.5 million for the year ended December 31, 2015 compared to $107.3 million and $93.2 million for the years ended December 31, 2014 and 2013, respectively. The effective income tax rate for the years ended December 31, 2015 and 2014 was 36.9% and 35.5%, respectively. The change in the effective rate is primarily due to the Company's recognition during 2014 of tax benefits from a favorable state filing position. Synovus currently expects an effective income tax rate of approximately 36% to 37% for the year ending December 31, 2016. The effective income tax rate in future periods could be affected by items that are infrequent in nature such as new legislation and changes in the deferred tax asset valuation allowance. See "Part II - Item 8. Financial Statements and Supplementary Data - Note 1 - Summary of Significant Accounting Policies and Note 22 - Income Taxes" of this Report for additional discussion regarding deferred income taxes.

Deferred tax assets represent amounts available to reduce income taxes payable in future years. At December 31, 2015, total deferred tax assets, net of valuation allowance, were $511.9 million compared to $622.5 million at December 31, 2014. The decline is mainly due to the utilization of NOL carryforwards.

Management evaluates the realizability of deferred tax assets at each reporting period. The determination of whether a valuation allowance for deferred tax assets is appropriate is subject to considerable judgment and requires an evaluation of all positive and negative evidence. Based on the weight of all the positive and negative evidence at December 31, 2015, management has concluded that it is more likely than not that the results of future operations will generate sufficient taxable income to realize the deferred tax assets. The valuation allowance of $11.7 million at December 31, 2015 is related to specific state income tax credits that have various expiration dates through the tax year 2025 and are expected to expire before they can be utilized.

The positive evidence supporting the realization of the Company’s deferred tax assets at December 31, 2015 includes generation of taxable income in 2012 through 2015, continued improvement in credit quality, record of long-term positive earnings prior to the most recent economic downturn, the Company’s strong capital position, as well as sufficient amounts of projected future taxable income, of the appropriate character, to support the realization of $511.9 million of the Company’s net deferred tax asset. Management's confidence in the realization of projected future taxable income is based on an analysis of the Company's risk profile and trends in financial performance, including credit quality trends. In determining whether management's projections of future taxable income are reliable, management considered objective evidence supporting the forecast assumptions as well as actual results over the past three years which demonstrate the Company's ability to reasonably project future results of operations.

Synovus expects to realize the $511.9 million in net deferred tax assets well in advance of the statutory carryforward period. $256.8 million or 50.2% of the net deferred tax asset at December 31, 2015 relates to Federal net operating losses which have expiration dates beginning in 2030 through 2032. Approximately $733.7 million in taxable income must be generated to allow for the realization of the corresponding deferred tax asset. Additionally, $155.6 million of the net deferred tax assets have no expiration date as of December 31, 2015. See “Part II - Item 8. Financial Statements and Supplementary Data - Note 22 - Income Taxes" of this Report for additional information regarding Federal and state NOL and tax credit carryforwards by expiration date.

Future changes in the tax laws could significantly impact Synovus' income tax expense, deferred tax asset balance, and the amount of taxes payable. Current proposals to lower the Federal corporate income tax rate would result in a reduction to our deferred tax asset balance upon enactment of the new tax legislation, with a corresponding one-time, non-cash increase in income tax expense.  Such increase in income tax expense could be material to our results of operations. However, our income tax expense would be reduced in subsequent periods, thus benefiting after-tax profitability.  

The Tax Reform Act of 1986 contains provisions that limit the utilization of NOL carryovers if there has been an “ownership change” as defined in Section 382 of the Code. In general, this would occur if ownership of common stock held by one or more 5% shareholders increased by more than 50 percentage points over their lowest pre-change ownership within a three-year period. If Synovus experiences such an ownership change, the utilization of pre-change NOLs to reduce future federal income tax obligations could be limited. To reduce the likelihood of such an ownership change, Synovus adopted a Rights Plan in 2010 that was ratified by Synovus shareholders in 2011. The Rights Plan was renewed on April 24, 2013, was ratified by Synovus shareholders in 2014 and will expire on April 28, 2016. See “Part I - Item 1A. Risk Factors - Issuances or sales of common stock or other equity securities could result in an “ownership change” as defined for U.S. federal income tax purposes. In the event an “ownership change” were to occur, our ability to fully utilize a significant portion of our U.S. federal and state tax net operating losses and certain built-in losses that have not been recognized for tax purposes could be impaired as a result of the operation of Section 382 of the Code."

Credit Quality

During 2015, credit quality continued to improve, with all key credit quality measures improving from 2014 levels.

Total credit costs

Total credit costs (provision for loan losses plus other credit costs which consist primarily of foreclosed real estate expense, net and other loan expenses) for the years ended December 31, 2015, 2014, and 2013 were $50.7 million, $66.7 million, and $118.0 million, respectively, including provision for loan losses of $19.0 million, $33.8 million and $69.6 million, respectively, and net expenses related to foreclosed real estate of $22.8 million, $25.3 million, and $33.9 million, respectively. Total credit costs for 2015 declined $16.0 million or 24.0% from 2014, driven primarily by a $14.8 million or 43.8% decrease in provision for loan losses and lower net foreclosed real estate expenses. Total credit costs for 2014 declined $51.3 million or 43.5% from 2013, driven primarily by a $35.8 million or 51.4% decrease in provision for loan losses and lower net foreclosed real estate expenses. Total credit costs for 2013 declined $314.6 million or 72.7% from 2012, driven primarily by a $250.8 million decrease in provision for loan losses and lower net foreclosed real estate expenses, since 2012 included the effect of approximately $157 million in credit costs from the sale of distressed assets completed during the fourth quarter of 2012.

Non-performing Assets

Total NPAs were $215.4 million at December 31, 2015, a $71.4 million or 24.9% decrease from $286.8 million at December 31, 2014. The decline in non-performing assets was primarily due to resolution and disposition of non-performing assets, lower NPL inflows, and charge-offs. Total non-performing assets as a percentage of total loans, other loans held for sale, and other real estate declined 39 basis points to 0.96% at December 31, 2015 compared to 1.35% at December 31, 2014. NPAs are expected to continue to decline modestly in 2016.

Non-performing loans were $168.4 million at December 31, 2015, a $29.4 million or 14.9% decrease from $197.8 million at December 31, 2014. The decline was driven by a $31.0 million or 22.9% decrease in NPL inflows and resolution and disposition of distressed loans (which includes some performing loans). Total non-performing loans as a percentage of total loans were 0.75% at December 31, 2015 compared to 0.94% at December 31, 2014.

ORE was $47.0 million at December 31, 2015, down $38.4 million or 45.0% from $85.5 million at December 31, 2014. The decline from 2014 was driven by sales, fewer properties being transferred into other real estate, and to a lesser extent, write-downs for declines in fair value subsequent to foreclosure. ORE sales for 2015 were $51.1 million compared to $71.4 million in 2014.

The following table shows the components of NPAs by portfolio class at December 31, 2015 and 2014.

Asset Dispositions

During 2015, 2014 and 2013, Synovus completed sales of distressed assets (consisting primarily of NPLs and ORE) with total carrying values of $79.3 million, $119.1 million, and $251.6 million, respectively. Distressed asset sales have been a component of Synovus' strategy to further strengthen the balance sheet, improve asset quality, and enhance future earnings. This component of Synovus' strategy is expected to continue at a measured pace in 2016 as resolution of the lower level of legacy problem credits continues.

Troubled Debt Restructurings

When borrowers are experiencing financial difficulties, the Company may, in order to assist the borrowers in repaying the principal and interest owed to the Company, make certain modifications to the borrower's loan. All loan modifications, renewals, and refinances are evaluated for troubled debt restructuring classification. In accordance with ASU 2011-02, A Creditor's Determination of Whether a Restructuring is a Troubled Debt Restructuring, issued in April 2011, a TDR is defined as a modification with a borrower that is experiencing financial difficulties, and the creditor has granted a financial concession that it would not normally make. The market interest rate concept in ASU 2011-02 states that if a borrower does not otherwise have access to funds at a market interest rate for debt with characteristics similar to those of the restructured debt, the restructuring would be considered to be at a below-market rate, which indicates that the lender may have granted a concession. Since Synovus often decreases or maintains the interest rate upon renewal of a commercial loan, including renewals of loans involving borrowers experiencing financial difficulties, the market rate concept has become a significant factor in determining if a loan is classified as a TDR. All TDR's are considered to be impaired loans, and the amount of impairment, if any, is determined in accordance with ASC 310-10-35, Accounting By Creditors for Impairment of a Loan-an amendment of FASB Statements No. 5, ASC 450-20, and No. 15, ASC 310-40.

Concessions provided by Synovus in a TDR are generally made in order to assist borrowers so that debt service is not interrupted and to mitigate the potential for loan losses. A number of factors are reviewed when a loan is renewed, refinanced, or modified, including cash flows, collateral values, guarantees, and loan structures. Concessions are primarily in the form of providing a below market interest rate given the borrower's credit risk to assist the borrower in managing cash flows, an extension of the maturity of the loan generally for less than one year, or a period of time generally less than one year with a reduction of required principal and/or interest payments (e.g., interest only for a period of time). These types of concessions may be made during the term of a loan or upon the maturity of a loan, as a loan renewal. Renewals of loans made to borrowers experiencing financial difficulties are evaluated for TDR designation by determining if concessions are being granted, including consideration of whether the renewed loan has an interest rate that is at market, given the credit risk related to the loan. Insignificant periods of reduction of principal and/or interest payments, or one time deferrals of three months or less, are generally not considered to be financial concessions. Further, it is generally Synovus' practice not to defer principal and/or interest for more than twelve months.

Non-accruing TDRs may generally be returned to accrual status if there has been a period of performance, consisting usually of at least a six month sustained period of repayment performance in accordance with the terms of the agreement. Consistent with regulatory guidance, a TDR will generally no longer be reported as a TDR after a period of performance which is generally a minimum of six months and after the loan has been reported as a TDR at a year-end reporting date, and if at the time of the modification, the interest rate was at market, considering the credit risk associated with the borrower.

At December 31, 2015, troubled debt restructurings (accruing and non-accruing) were $271.3 million, a decrease of $151.8 million or 35.9% compared to December 31, 2014. Non-accruing TDRs of $47.4 million at December 31, 2015 decreased $27.2

65

million or 36.5% from December 31, 2014, primarily due to principal reductions. Accruing TDRs were $223.9 million at December 31, 2015 compared to $348.4 million at December 31, 2014, a decrease of $124.6 million or 35.7%, primarily due to a decline in TDR inflows as well as fewer TDRs having to retain the TDR designation upon subsequent renewal, refinance, or modification. At December 31, 2015, the allowance for loan losses allocated to these accruing TDRs was $12.6 million compared to $21.0 million at December 31, 2014. The allowance for loan losses allocated to accruing TDRs has declined due to the decreased level of accruing TDRs. Accruing TDRs are considered performing because they are performing in accordance with the restructured terms. At both December 31, 2015 and 2014, approximately 99% of accruing TDRs were current.

The table below shows accruing TDRs by grade at December 31, 2015 and 2014.

Past Due Loans

Loans past due 90 days or more, which based on a determination of collectability are accruing interest, are classified as past due loans. Synovus’ policy discourages making additional loans to a borrower or any related interest of the borrower who has a loan that is past due as to principal or interest more than 90 days and remains on accruing status. Additionally, Synovus’ policy prohibits making additional loans to a borrower, or any related interest of a borrower, who is on nonaccrual status except under certain workout plans and if such extension of credit aids with loss mitigation.

Past due loans have remained at low levels. As a percentage of total loans outstanding, loans 90 days past due and still accruing interest were 0.01% and 0.02% at December 31, 2015 and 2014, respectively. These loans are in the process of collection, and management believes that sufficient collateral value securing these loans exists to cover contractual interest and principal payments. As a percentage of total loans outstanding, loans 30 or more days past due and still accruing interest were 0.21% and 0.24% at December 31, 2015 and 2014, respectively, with improvements in every category.

Potential Problem Loans

Management continuously monitors non-performing and past due loans to mitigate further deterioration regarding the condition of these loans. Potential problem loans are defined by management as certain performing loans with a well-defined weakness where there is information about possible credit problems of borrowers which causes management to have doubts as to the ability of such borrowers to comply with the present repayment terms of such loans. Potential problem commercial loans consist of substandard accruing loans but exclude both loans 90 days past due and still accruing interest and substandard accruing troubled debt restructurings, which are reported separately. Management’s decision to include performing loans in the category of potential problem loans indicates that management has recognized a higher degree of risk associated with these loans. In addition to accruing loans 90 days past due and accruing restructured loans, Synovus had $181.0 million of potential problem commercial loans at December 31, 2015 compared to $222.5 million at December 31, 2014. Management’s current expectation of probable losses from potential problem loans is included in the allowance for loan losses, and management cannot predict at this time whether these potential problem loans ultimately will become non-performing loans or result in losses.

Net Charge-offs

Total net charge-offs were $27.8 million, or 0.13% of average loans for 2015, a decrease of $51.2 million or 64.8%, compared to $79.1 million or 0.39% of average loans for 2014. Total net charge-offs were $79.1 million, or 0.39% of average loans for 2014, a decrease of $56.4 million or 41.6%, compared to $135.4 million or 0.69% of average loans for 2013. Net charge-offs have declined primarily as a result of lower mark-to-market charges, decreased charge-offs related to NPL inflows, and lower charges on the resolution and disposition of distressed loans. Net charge-offs for 2016 are expected to be in the 20 to 30 basis points range.

Provision for Loan Losses and Allowance for Loan Losses

See "Part II - Item 8. Financial Statements and Supplementary Data - Note 5 - Loans and Allowance for Loan Losses" and "Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Policies" of this Report for further information.

The provision for loan losses for the year ended December 31, 2015 was $19.0 million, a decrease of $14.8 million or 43.8% compared to 2014. The provision for loan losses for the year ended December 31, 2014 was $33.8 million, a decrease of $35.8 million or 51.4% compared to 2013. The decreases in the provision for loan losses from 2014 to 2015 and 2013 to 2014 are primarily due to continued improvement in credit quality during 2015 and 2014, including reduced NPL inflows and NPLs, lower net charge-offs, and lower levels of loans rated special mention and accruing substandard.

The allowance for loan losses at December 31, 2015 was $252.5 million or 1.13% of total loans, compared to $261.3 million or 1.24% of total loans at December 31, 2014. The decrease in the allowance for loan losses during 2015 was due to the continued improvement in credit quality during 2015. The improvements in credit quality included reduced NPL inflows and NPLs, lower net charge-offs, and lower levels of loans rated special mention and accruing substandard.

Capital Resources

Synovus is required to comply with the capital adequacy standards established by the Federal Reserve Board and our subsidiary bank, Synovus Bank, must comply with similar capital adequacy standards established by the FDIC. Synovus has always placed great emphasis on maintaining a solid capital base and continues to satisfy applicable regulatory capital requirements.

At December 31, 2015, Synovus' and Synovus Bank's capital levels each exceeded well-capitalized requirements currently in effect. The following table presents certain ratios used to measure Synovus and Synovus Bank's capitalization.

The Basel III capital rules, implemented in the U.S. with certain changes mandated by the Dodd-Frank Act, strengthen the definition of regulatory capital, increase risk-based capital requirements, and make selected changes to the calculation of risk-weighted assets. The rules became effective January 1, 2015, for Synovus and Synovus Bank, subject to a transition period for several aspects, including the capital conservation buffer and certain regulatory capital adjustments and deductions, as described below. Under the Basel III capital rules, the minimum capital requirements for Synovus and Synovus Bank include a common equity Tier 1 (CET1) ratio of 4.5%; Tier 1 capital ratio of 6%; total capital ratio of 8%; and leverage ratio of 4%. When fully phased-in on January 1, 2019, the Basel III capital rules include a capital conservation buffer of 2.5% that is added on top of each of the minimum risk-based capital ratios. The implementation of the capital conservation buffer will begin on January 1, 2016 at the 0.625% level and be phased-in over a three-year period (increasing by that amount on each subsequent January 1, until it reaches 2.5% on January 1, 2019). As a financial holding company, Synovus and its subsidiary bank, Synovus Bank, are required

73

to maintain capital levels required for a well-capitalized institution as defined by federal banking regulations. Under the Basel III capital rules, Synovus and Synovus Bank are well-capitalized if each has a CET1 ratio of 6.5% or greater, a Tier 1 risk-based capital ratio of 8% or greater, a total risk-based capital ratio of 10% or greater, a leverage ratio of 5% or greater, and are not subject to any written agreement, order, capital directive, or prompt corrective action directive from a federal and/or state banking regulatory agency to meet and maintain a specific capital level for any capital measure.

During the third quarter of 2015, Synovus completed its $250 million share repurchase program which was announced on October 21, 2014 and expired on October 23, 2015. Under this program, Synovus repurchased 9.1 million shares of common stock through a combination of share repurchases under the accelerated share repurchase (ASR) agreement described below and open market transactions. Synovus entered into an ASR agreement during October 2014 to purchase $75.0 million of Synovus common stock under the share repurchase program. During 2014, Synovus repurchased 2.5 million shares of common stock under the ASR agreement. During January 2015, Synovus repurchased 392 thousand shares upon completion of the ASR agreement. Additionally, from October 2014 through September 30, 2015, Synovus repurchased $175.0 million, or 6.2 million shares, of common stock through open market transactions, including $161.9 million, or 5.7 million shares, of common stock repurchased during 2015.

During the third quarter of 2015, Synovus' Board of Directors authorized a $300 million share repurchase program to be completed over the next 15 months. During the fourth quarter of 2015, under the new $300 million share repurchase program, Synovus repurchased $37.1 million, or 1.2 million shares. From January 1, 2016 through February 26, 2016, Synovus has repurchased $106.5 million, or 3.7 million shares under the $300 million share repurchase program. At December 31, 2015, the remaining authorization under this program was $262.9 million and as of February 26, 2016, the remaining authorization under this program was $156.4 million.

On December 7, 2015, Synovus issued in a public offering $250 million aggregate principal amount of subordinated notes due in 2025, for aggregate proceeds of $246.6 million, net of debt issuance costs. Also during the fourth quarter of 2015, Synovus repurchased $46.7 million of its 2017 subordinated notes in privately negotiated transactions which resulted in a pre-tax loss of $1.5 million. Additionally, during January 2016, Synovus repurchased $124.7 million of the 2017 subordinated notes in conjunction with Synovus' cash tender offer that commenced on December 23, 2015 and expired on January 22, 2016. The first quarter of 2016 results will reflect a $4.7 million pre-tax loss relating to the January tender offer.

Additionally, 2015 capital ratios were impacted by changes required under Basel III capital rules, which, for Synovus, increased risk-weighted assets by approximately $420 million when the capital rules went into effect at March 31, 2015 with higher risk-weights assigned to certain categories including unfunded lines of credit, non-performing loans, and various other categories. Synovus and Synovus Bank elected to make a permanent election to exclude accumulated other comprehensive income (loss) from regulatory capital, and therefore will retain the same accumulated other comprehensive income (loss) treatment as under the regulatory capital rules in effect prior to January 1, 2015.

As of December 31, 2015, total disallowed deferred tax assets were $341.1 million or 1.33% of risk-weighted assets compared to $492.2 million or 2.10% of risk weighted assets at December 31, 2014. Disallowed deferred tax assets for the new Basel III ratio, CET1, were $215.5 million at December 31, 2015, due to a three-year phase-in of the total disallowed deferred tax asset for the CET1 capital measure. Basel III revised the deferred tax asset limitation criteria effective January 1, 2015 and now includes the component of deferred tax assets arising from temporary timing differences in regulatory capital up to certain levels of CET1. Thus, the disallowed portion of deferred tax assets, under Basel III, is comprised of NOL carryforwards and tax credit carryforwards. Under Basel I, there were limitations on the inclusion of deferred tax assets for regulatory capital based on Tier 1 capital levels and projected future earnings. The treatment of deferred tax assets under Basel III had an initial favorable impact on Synovus' regulatory capital ratios. Synovus' deferred tax asset is projected to continue to decline, thus creating additional regulatory capital in future periods.

Synovus' CET1 ratio was 10.37% at December 31, 2015 under Basel III transitional provisions and the estimated fully phased-in CET1 ratio, as of December 31, 2015, was 9.77%, both of which are well in excess of the regulatory requirements prescribed by Basel III.

Management currently believes, based on internal capital analyses and earnings projections, that Synovus' capital position is adequate to meet current and future regulatory minimum capital requirements.

Liquidity

Liquidity represents the extent to which Synovus has readily available sources of funding needed to meet the needs of depositors, borrowers and creditors, to support asset growth, and to otherwise sustain operations of Synovus and its subsidiaries, at a reasonable cost, on a timely basis, and without adverse consequences. ALCO monitors Synovus' economic, competitive, and regulatory environment and is responsible for measuring, monitoring, and reporting on liquidity and funding risk, interest rate risk, and market risk and has the authority to establish policies relative to these risks. ALCO, operating under liquidity and funding policies approved by the Board of Directors, actively analyzes contractual and anticipated cash flows in order to properly manage Synovus’ liquidity position.

Contractual and anticipated cash flows are analyzed under normal and stressed conditions to determine forward looking liquidity needs and sources. Synovus analyzes liquidity needs under various scenarios of market conditions and operating performance. This analysis includes stress testing and measures expected sources and uses of funds under each scenario. Emphasis is placed on maintaining numerous sources of current and potential liquidity to allow Synovus to meet its obligations to depositors, borrowers, and creditors on a timely basis.

Liquidity is generated primarily through maturities and repayments of loans by customers, maturities and sales of investment securities, deposit growth, and access to sources of funds other than deposits. Management continuously monitors and maintains appropriate levels of liquidity so as to provide adequate funding sources to manage customer deposit withdrawals, loan requests, and funding maturities. Liquidity is also enhanced by the acquisition of new deposits. Each of the banking divisions monitors deposit flows and evaluates local market conditions in an effort to retain and grow deposits.

Synovus Bank also generates liquidity through the national deposit markets through the issuance of brokered certificates of deposit and money market accounts. Synovus Bank accesses these funds from a broad geographic base to diversify its sources of funding and liquidity. Synovus Bank has the capacity to access funding through its membership in the FHLB System. At December 31, 2015, Synovus Bank had access to incremental funding, subject to available collateral and FHLB credit policies, through utilization of FHLB advances.

In addition to bank level liquidity management, Synovus must manage liquidity at the Parent Company for various operating needs including potential capital infusions into subsidiaries, the servicing of debt, the payment of dividends on our common stock and preferred stock, share repurchases and payment of general corporate expenses. The primary source of liquidity for Synovus consists of dividends from Synovus Bank, which is governed by certain rules and regulations of the GA DBF and FDIC. During 2014, Synovus Bank made upstream cash distributions to the Parent Company totaling $182.0 million including cash dividends of $90.6 million. During 2015, Synovus Bank made upstream cash distributions to the Parent Company totaling $225.0 million including cash dividends of $199.9 million. On February 12, 2016, Synovus Bank paid an upstream cash dividend of $100.0 million to the Parent Company. Synovus' ability to receive dividends from Synovus Bank in future periods will depend on a number of factors, including, without limitation, Synovus Bank's future profits, asset quality, liquidity and overall condition. In addition, GA DBF rules and related statutes contain limitations on payments of dividends by Synovus Bank without the approval of the GA DBF.

On December 7, 2015, Synovus issued in a public offering $250 million aggregate principal amount of subordinated debt due in 2025, for aggregate proceeds of $246.6 million, net of debt issuance costs. Also during the fourth quarter of 2015, Synovus repurchased $46.7 million of its subordinated notes maturing in 2017 in privately negotiated transactions which resulted in a pre-tax loss of $1.5 million. Additionally, during January 2016, Synovus repurchased $124.7 million of the 2017 notes in conjunction with Synovus' cash tender offer that commenced on December 23, 2015 and expired on January 22, 2016. The first quarter of 2016 results will reflect a $4.7 million pre-tax loss relating to the January tender offer.

Synovus presently believes that the sources of liquidity discussed above, including existing liquid funds on hand, are sufficient to meet its anticipated funding needs. However, if economic conditions were to significantly deteriorate, regulatory capital requirements for Synovus or Synovus Bank increase as the result of regulatory directives or otherwise, or Synovus believes it is prudent to enhance current liquidity levels, then Synovus may seek additional liquidity from external sources. See "Part I – Item 1A. Risk Factors - Changes in the cost and availability of funding due to changes in the deposit market and credit market, or the way in which we are perceived in such markets, may adversely affect our capital resources, liquidity and financial results."

Earning Assets and Sources of Funds

Average total assets for 2015 increased $1.56 billion, or 5.9%, to $28.10 billion as compared to average total assets for 2014. Average earning assets increased $1.69 billion, or 7.0%, in 2015 as compared to the prior year. Average earning assets represented 92.5% and 91.6% of average total assets for 2015 and 2014, respectively. The increase in average earning assets resulted primarily from a $1.14 billion increase in average loans, net, a $379.9 million increase in average interest bearing funds at the Federal Reserve Bank, and a $174.4 million increase in average taxable investment securities. Average non-interest bearing funds and average money market deposits increased by $781.1 million and $653.1 million, respectively and represented the primary funding source growth for the year.

Average total assets for 2014 increased $207.1 million, or 0.8%, to $26.54 billion as compared to average total assets for 2013. Average earning assets increased $391.0 million, or 1.6%, in 2014 as compared to the prior year. Average earning assets represented 91.6% and 90.8% of average total assets for 2014 and 2013, respectively. The increase in average earning assets resulted primarily from a $886.0 million increase in average loans, net. The increase was partially offset by a $437.1 million reduction in average interest bearing funds at the Federal Reserve Bank, and a $52.2 million decrease in average mortgage loans held for sale. Average non-interest bearing funds increased by $389.0 million and represented the primary funding source growth for the year.

The table below shows the maturity of selected loan categories as of December 31, 2015. Also provided are the amounts due after one year classified according to the sensitivity in interest rates. Actual repayments of loans may differ from the contractual maturities reflected therein because borrowers have the right to prepay obligations with and without prepayment penalties. Additionally, the refinancing of such loans or the potential delinquency of such loans could create differences between the contractual maturities and the actual repayment of such loans.

The measures entitled adjusted pre-tax, pre-credit costs income, adjusted non-interest income, adjusted non-interest expense, adjusted efficiency ratio, average core deposits, average core deposits excluding average state, county, and municipal deposits, Tier 1 common equity, Tier 1 common equity ratio, estimated common equity Tier 1 (CET1) ratio (transitional), common equity Tier 1 (CET1) ratio (fully phased-in), and tangible common equity to tangible assets ratio are not measures recognized under U.S. GAAP and therefore are considered non-GAAP financial measures. The most comparable GAAP measures are income (loss) before income taxes, total non-interest income, total non-interest expense, efficiency ratio, total average deposits, total shareholders' equity, and the ratio of total shareholders’ equity to total assets, respectively.

Synovus believes that these non-GAAP financial measures provide meaningful additional information about Synovus to assist management and investors in evaluating Synovus’ capital strength and the performance of its core business. These non-GAAP financial measures should not be considered as substitutes for income (loss) before income taxes, total non-interest income, total non-interest expense, efficiency ratio, total average deposits, total shareholders' equity, or the ratio of total shareholders’ equity to total assets determined in accordance with GAAP and may not be comparable to other similarly titled measures at other companies.

The computations of adjusted pre-tax, pre-credit costs income, adjusted non-interest income, adjusted non-interest expense, adjusted efficiency ratio, average core deposits, average core deposits excluding average state, county, and municipal deposits, Tier 1 common equity, Tier 1 common equity ratio, estimated common equity Tier 1 (CET1) ratio (transitional), common equity Tier 1 (CET1) ratio (fully phased-in), tangible common equity to tangible assets ratio, and the reconciliation of these measures to income (loss) before income taxes, total non-interest income, total non-interest expense, efficiency ratio, total average deposits, total shareholders' equity and the ratio of total shareholders’ equity to total assets are set forth in the tables below.

Inflation

A financial institution’s assets and liabilities are primarily monetary in nature; therefore, inflation can have an important impact on the growth of total assets in the banking industry and may create a need to increase equity capital at higher than normal rates in order to maintain appropriate capital ratios. Interest rate levels are also significantly influenced by changes in the rate of inflation although they do not necessarily change at the same time or magnitude as the inflation rate. These changes could adversely impact Synovus’ financial position and profitability. Synovus attempts to mitigate the effects of inflation and changing interest rates by managing its interest rate sensitivity position through its asset/liability management practices and by periodically adjusting its pricing of services and banking products in an effort to take into consideration such costs. See "Part II - Item 7A. Market Risk and Interest Rate Sensitivity” of this Report for further information.

Deflation

An extended period of deflation could negatively impact the banking industry and may be associated with lower growth and a general deterioration of the economy. Such a scenario could impair bank earnings and profitability in a variety of ways including, but not limited to, decreases in the value of collateral for loans, a diminished ability of borrowers to service their debts, increases in the value of certain bank liabilities, and lessened demand for loans. While these effects cannot be fully accounted for, Synovus attempts to mitigate such risks through prudent underwriting of loans and through the management of its interest rate sensitivity position.

Parent Company

The Parent Company’s net assets consist primarily of its investment in Synovus Bank. The Parent Company’s primary uses of cash are for the servicing of debt and payment of dividends to shareholders. The Parent Company also provides the necessary funds to strengthen the capital of its subsidiaries if needed. These uses of cash are primarily funded by dividends from Synovus Bank, borrowings from external sources, and equity offerings.

Synovus returned over $250 million in capital to common shareholders with $199.2 million of common stock repurchases and $55.4 million of common stock dividends during 2015. During the fourth quarter of 2015, Synovus increased the quarterly common stock dividend by 20% to $0.12 per share effective with the quarterly dividend paid on January 4, 2016.

During the third quarter of 2015, Synovus completed its $250 million share repurchase program which was announced on October 21, 2014 and expired on October 23, 2015. Under this program, Synovus repurchased 9.1 million shares of common stock through a combination of share repurchases under the accelerated share repurchase (ASR) agreement described below and open market transactions. Synovus entered into an ASR agreement during October 2014 to purchase $75.0 million of Synovus common stock under the share repurchase program. During 2014, Synovus repurchased 2.5 million shares of common stock under the ASR agreement. During January 2015, Synovus repurchased 392 thousand shares upon completion of the ASR agreement. Additionally, from October 2014 through September 30, 2015, Synovus repurchased $175.0 million, or 6.2 million shares, of common stock through open market transactions, including $161.9 million, or 5.7 million shares, of common stock repurchased during 2015.

During the third quarter of 2015, Synovus' Board of Directors authorized a $300 million share repurchase program to be completed over the next 15 months. During the fourth quarter of 2015, under the new $300 million share repurchase program, Synovus repurchased $37.1 million, or 1.2 million shares. From January 1, 2016 through February 26, 2016, Synovus has repurchased $106.5 million, or 3.7 million shares under the $300 million share repurchase program. At December 31, 2015, the remaining authorization under this program was $262.9 million and as of February 26, 2016, the remaining authorization under this program was $156.4 million.

On December 7, 2015, Synovus issued in a public offering $250 million aggregate principal amount of subordinated notes due in 2025, for aggregate proceeds of $246.6 million, net of debt issuance costs. Also during the fourth quarter of 2015, Synovus repurchased $46.7 million of its 2017 subordinated notes in privately negotiated transactions which resulted in a pre-tax loss of $1.5 million. Additionally, during January 2016, Synovus repurchased $124.7 million of the 2017 subordinated notes in conjunction with Synovus' cash tender offer that commenced on December 23, 2015 and expired on January 22, 2016. The first quarter of 2016 results will reflect a $4.7 million pre-tax loss relating to the January tender offer.

On February 12, 2016, Synovus Bank paid an upstream cash dividend of $100.0 million to the Parent Company. During 2015, Synovus Bank made upstream cash distributions to the Parent Company totaling $225.0 million including cash dividends of $199.9 million. During 2014, Synovus Bank made upstream cash distributions to the Parent Company totaling $182.0 million including cash dividends of $90.6 million. On July 19, 2013, the Parent Company received an upstream cash distribution of $680.0 million from Synovus Bank, which Synovus utilized to redeem its $967.9 million of Series A Preferred Stock on July 26, 2013. The balance of the redemption was funded by net proceeds from equity offerings completed in July 2013, described below.

80

On July 24, 2013, Synovus completed a public offering of 8,552,936 shares of its common stock at $21.63 per share. The offering generated net proceeds of $175.2 million. On July 25, 2013, Synovus completed a public offering of $130 million of Series C Preferred Stock.  The offering generated net proceeds of $126.0 million. From the date of issuance to, but excluding, August 1, 2018, the rate for declared dividends on the Series C Preferred Stock is 7.875% per annum.  From and including August 1, 2018, the dividend rate will change to a floating rate equal to the three-month LIBOR plus a spread of 6.39% per annum.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk and Interest Rate Sensitivity

Market risk reflects the risk of economic loss resulting from adverse changes in market prices and interest rates. This risk of loss can be reflected in either diminished current market values or reduced current and potential net income. Synovus’ most significant market risk is interest rate risk. This risk arises primarily from Synovus’ core community banking activities of extending loans and accepting deposits.

Managing interest rate risk is a primary goal of the asset liability management function. Synovus attempts to achieve consistency in net interest income while limiting volatility arising from changes in interest rates. Synovus seeks to accomplish this goal by balancing the maturity and repricing characteristics of assets and liabilities along with the selective use of derivative instruments. Synovus manages its exposure to fluctuations in interest rates through policies established by ALCO and approved by the Board of Directors. ALCO meets periodically and has responsibility for developing asset liability management policies, reviewing the interest rate sensitivity of Synovus, and developing and implementing strategies to improve balance sheet structure and interest rate risk positioning.

Synovus measures the sensitivity of net interest income to changes in market interest rates through the utilization of simulation modeling. On at least a quarterly basis, the following twenty-four month time period is simulated to determine a baseline net interest income forecast and the sensitivity of this forecast to changes in interest rates. These simulations include all of Synovus’ earning assets and liabilities. Forecasted balance sheet changes, primarily reflecting loan and deposit growth and forecasts, are included in the periods modeled. Projected rates for loans and deposits are based on management’s outlook and local market conditions. Anticipated deposit mix changes in each interest rate scenario are also included in the periods modeled.

The magnitude and velocity of rate changes among the various asset and liability groups exhibit different characteristics for each possible interest rate scenario; additionally, customer loan and deposit preferences can vary in response to changing interest rates. Simulation modeling enables Synovus to capture the expected effect of these differences. Assumptions utilized in the model are updated on an ongoing basis and are reviewed and approved by ALCO and the Risk Committee of the Board of Directors. Synovus is also able to model expected changes in the shape of interest rate yield curves for each rate scenario. Simulation also enables Synovus to capture the effect of expected prepayment level changes on selected assets and liabilities subject to prepayment.

Synovus has modeled its baseline net interest income forecast assuming a flat interest rate environment with the federal funds rate at the Federal Reserve's current targeted range of 0.25% to 0.50% and the current prime rate of 3.50%. Synovus has modeled the impact of a gradual increase in short-term rates of 100 and 200 basis points and a decline of 25 basis points to determine the sensitivity of net interest income for the next twelve months. As illustrated in the table below, the net interest income sensitivity model indicates that, compared with a net interest income forecast assuming stable rates, net interest income is projected to increase by 3.8% and increase by 6.4% if interest rates increased by 100 and 200 basis points, respectively. Net interest income is projected to decline by 2.6% if interest rates decreased by 25 basis points. This metric was not measured at December 31, 2014 as the Federal Reserve's targeted federal funds range was 0% to 0.25% at that time. These changes were within Synovus’ policy limit of a maximum 5% negative change.

Table 40 - Twelve Month Net Interest Income Sensitivity
Change in Short-term Interest Rates (in basis points)	Estimated Change in Net Interest Income As of December 31,
	2015	2014
+200	6.4%	6.7%
+100	3.8%	4.3%
Flat	—%	—%
-25	-2.6%	N/A

The measured interest rate sensitivity indicates an asset sensitive position over the next year, which could serve to improve net interest income in a rising interest rate environment. The actual realized change in net interest income would depend on several factors, some of which could serve to diminish or eliminate the asset sensitivity noted above. These factors include a higher than

81

projected level of deposit customer migration to higher cost deposits, such as certificates of deposit, which would increase total interest expense and serve to reduce the realized level of asset sensitivity. Another factor which could impact the realized interest rate sensitivity in a rising rate environment is the repricing behavior of interest bearing non-maturity deposits. Assumptions for repricing are expressed as a beta relative to the change in the prime rate. For instance, a 50% beta would correspond to a deposit rate that would increase 0.5% for every 1% increase in the prime rate. Projected betas for interest bearing non-maturity deposit repricing are a key component of determining the Company's interest rate risk position. Should realized betas be higher than projected betas, the expected benefit from higher interest rates would be diminished. The following table presents an example of the potential impact of an increase in repricing betas in a rising rate environment on Synovus' realized interest rate sensitivity position.

Table 41 - Core Deposit Beta Sensitivity
Change in Short-term Interest Rates (in basis points)	As of December 31, 2015
	Base Scenario	15% Increase in Average Repricing Beta
+200	6.4%	4.8%
+100	3.8%	2.9%

While all of the above estimates are reflective of the general interest rate sensitivity of Synovus, local market conditions and their impact on loan and deposit pricing would be expected to have a significant impact on the realized level of net interest income. Actual realized balance sheet growth and mix would also impact the realized level of net interest income.

The net interest income simulation model is the primary tool utilized to evaluate potential interest rate risks over a shorter term time horizon. Synovus also evaluates potential longer term interest rate risk through modeling and evaluation of economic value of equity (EVE). This EVE modeling allows Synovus to capture longer-term repricing risk and options risk embedded in the balance sheet. Simulation modeling is utilized to measure the economic value of equity and its sensitivity to immediate changes in interest rates. These simulations value only the current balance sheet and do not incorporate growth assumptions used in the net interest income simulation. The economic value of equity is the net fair value of assets, liabilities, and off-balance sheet financial instruments derived from the present value of future cash flows discounted at current market interest rates. From this baseline valuation, Synovus evaluates changes in the value of each of these items in various interest rate scenarios to determine the net impact on the economic value of equity. Key assumptions utilized in the model, namely loan prepayments, deposit pricing betas, and non-maturity deposit durations have a significant impact on the results of the EVE simulations.

As illustrated in the table below, the economic value of equity model indicates that, compared with a valuation assuming stable rates, EVE is projected to increase by 3.4% and 3.2%, assuming an immediate and sustained increase in interest rates of 100 and 200 basis points, respectively. The primary reason for the decline in asset sensitivity from the prior year is a more conservative assumption regarding non-maturity deposit durations resulting from our annual evaluation of these deposit accounts. Assuming an immediate 25 basis point decline in rates, EVE is projected to decrease by .7%. These changes were within Synovus' policy which limits the maximum negative change in EVE to 20% of the base EVE.

Table 42 - Economic Value of Equity Sensitivity
Immediate Change in Interest Rates (in basis points)	Estimated Change in EVE As of December 31,
	2015	2014
+200	3.2%	6.7%
+100	3.4%	4.4%
- 25	- 0.7%	N/A

Synovus is also subject to market risk in certain of its fee income business lines. Financial management services revenues, which include trust, brokerage, and asset management fees, can be affected by risk in the securities markets, primarily the equity securities market. A significant portion of the fees in this unit are determined based upon a percentage of asset values. Weaker securities markets and lower equity values have an adverse impact on the fees generated by these operations. Trading account assets, maintained to facilitate brokerage customer activity, are also subject to market risk. This risk is not considered significant, as trading activities are limited and subject to risk policy limits. Mortgage banking income is also subject to market risk. Mortgage loan originations are sensitive to levels of mortgage interest rates and therefore, mortgage banking income could be negatively impacted during a period of rising interest rates. The extension of commitments to customers to fund mortgage loans also subjects Synovus to market risk. This risk is primarily created by the time period between making the commitment and closing and

82

delivering the loan. Synovus seeks to minimize this exposure by utilizing various risk management tools, the primary of which are forward sales commitments and best efforts commitments.

Derivative Instruments for Interest Rate Risk Management

As part of its overall interest rate risk management activities, Synovus utilizes derivative instruments to manage its exposure to various types of interest rate risks. These derivative instruments generally consist of interest rate swaps, interest rate lock commitments made to prospective mortgage loan customers, and commitments to sell fixed-rate mortgage loans. Interest rate lock commitments represent derivative instruments when it is intended that such loans will be sold.

Synovus may also utilize interest rate swaps to manage interest rate risks primarily arising from its core banking activities. These interest rate swap transactions generally involve the exchange of fixed and floating interest rate payment obligations without the exchange of underlying principal amounts. Swaps may be designated as either cash flow hedges or fair value hedges. As of December 31, 2015 and December 31, 2014, Synovus had no outstanding interest rate swap contracts utilized to manage interest rate risk.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders

Synovus Financial Corp.:

We have audited Synovus Financial Corp.’s internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Synovus Financial Corp.’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Synovus Financial Corp. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control - Integrated Framework(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Synovus Financial Corp. andsubsidiaries as of December 31, 2015 and 2014, and the related consolidated statements of income, comprehensive income, changes in shareholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2015, and our report dated February 29, 2016 expressed an unqualified opinion on those consolidated financial statements.

Note 1 - Summary of Significant Accounting Policies

Business Operations

The consolidated financial statements of Synovus include the accounts of the Parent Company and its consolidated subsidiaries. Synovus provides integrated financial services, including commercial and retail banking, financial management, insurance, and mortgage services to its customers through locally-branded divisions of its wholly-owned subsidiary bank, Synovus Bank, in offices located throughout Georgia, Alabama, South Carolina, Florida, and Tennessee.

In addition to our banking operations, we also provide various other financial services to our customers through direct and indirect wholly-owned non-bank subsidiaries, including: Synovus Securities, Inc., headquartered in Columbus, Georgia, which specializes in professional portfolio management for fixed-income securities, investment banking, the execution of securities transactions as a broker/dealer and the provision of individual investment advice on equity and other securities; Synovus Trust Company, N.A., headquartered in Columbus, Georgia, which provides trust, asset management and financial planning services; and Synovus Mortgage Corp., headquartered in Birmingham, Alabama, which offers mortgage services.

Basis of Presentation

The accounting and financial reporting policies of Synovus are in accordance with U.S. GAAP and conform to the accounting and reporting guidelines prescribed by bank regulatory authorities. All significant intercompany accounts and transactions have been eliminated in consolidation. In preparing the consolidated financial statements in accordance with U.S. GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the respective consolidated balance sheets and the reported amounts of revenues and expenses for the periods presented. Actual results could differ significantly from those estimates.

Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses; the valuation of other real estate; the fair value of investment securities; the fair value of private equity investments; contingent liabilities related to legal matters; and the deferred tax assets valuation allowance. In connection with the determination of the allowance for loan losses and the valuation of certain impaired loans and other real estate, management obtains independent appraisals for significant properties and properties collateralizing impaired loans. In making this determination, management also considers other factors or recent developments, such as changes in absorption rates or market conditions at the time of valuation and anticipated sales values based on management’s plans for disposition.

The following is a description of the Company's significant accounting policies.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash and due from banks. At December 31, 2015 and 2014, $100 thousand and $125 thousand, respectively, of the due from banks balance was restricted as to withdrawal.

Short-term Investments

Short-term investments consist of interest bearing funds with the Federal Reserve Bank, interest earning deposits with banks, and Federal funds sold and securities purchased under resale agreements. At December 31, 2015 and 2014, interest bearing funds with the Federal Reserve Bank included$117.3 million and $89.2 million, respectively, on deposit to meet Federal Reserve Bank reserve requirements. Interest earning deposits with banks include $2.2 million at December 31, 2015 and $7.1 million at December 31, 2014, which is pledged as collateral in connection with certain letters of credit. Federal funds sold include $65.9 million at December 31, 2015 and $67.5 million at December 31, 2014, which are pledged to collateralize certain derivative instruments. Federal funds sold and securities purchased under resale agreements, and Federal funds purchased and securities sold under repurchase agreements, generally mature in one day.

Trading Account Assets

Trading account assets, which are primarily held on a short-term basis for the purpose of selling at a profit, consist of debt and equity securities and are reported at fair value. Fair value adjustments and fees from trading account activities are included as a component of other fee income on the consolidated statements of income. Gains and losses realized from the sale of trading account assets are determined by specific identification and are included as a component of other fee income on the trade date. Interest income on trading assets is reported as a component of interest income on the consolidated statements of income.

92

Mortgage Loans Held for Sale and Mortgage Banking Income

Mortgage Loans Held for Sale

Mortgage loans held for sale are recorded at fair value. Fair value is derived from a hypothetical bulk sale model used to estimate the exit price of the loan in a loan sale. The bid pricing convention is used for loan pricing for similar assets. The valuation model is based upon forward settlements of a pool of loans of similar coupon, maturity, product, and credit attributes. The inputs to the model are continuously updated with available market and historical data. As the loans are sold in the secondary market, the valuation model produces an estimate of fair value that represents the highest and best use of the loans in Synovus' principal market.

Mortgage Banking Income

Mortgage banking income consists primarily of origination and ancillary fees on loans originated for sale, and gains and losses from the sale of mortgage loans. Mortgage loans are generally sold servicing released, without recourse or continuing involvement, and meet ASC 860-10-65, Transfers and Servicing of Financial Assets, criteria for sale accounting.

Other Loans Held for Sale

Loans are transferred to other loans held for sale at fair value when Synovus makes the determination to sell specifically identified loans. The fair value of the loans is primarily determined by analyzing the underlying collateral of the loan and the anticipated market prices of similar assets less estimated costs to sell. At the time of transfer, if the estimated fair value is less than the carrying amount, the difference is recorded as a charge-off against the allowance for loan losses. Decreases in the fair value subsequent to the transfer, as well as gains/losses realized from the sale of these assets, are recorded as losses on other loans held for sale, net, as a component of non-interest expense on the consolidated statements of income.

Investment Securities Available for Sale

Investment securities available for sale are carried at fair value with unrealized gains and losses, net of the related tax effect, excluded from earnings and reported as a separate component of shareholders' equity within accumulated other comprehensive income (loss) until realized.

Synovus performs a quarterly assessment of its investment securities available for sale to determine if the decline in fair value of a security below its amortized cost is deemed to be other-than-temporary. Factors included in the assessment include the length of time the security has been in a loss position, the extent that the fair value is below amortized cost, and the credit standing of the issuer. Other-than-temporary impairment losses are recognized on securities when: (1) the holder has an intention to sell the security; (2) it is more likely than not that the security will be required to be sold prior to recovery; or (3) the holder does not expect to recover the entire amortized cost basis of the security. Other-than-temporary impairment losses are reflected in earnings as realized losses to the extent the impairment is related to credit losses. The amount of the impairment related to other factors is recognized in other comprehensive income (loss).

Premiums and discounts are amortized or accreted over the life of the related security as an adjustment to yield using the effective interest method and prepayment assumptions. Actual prepayment experience is reviewed periodically and the timing of the accretion and amortization is adjusted accordingly. Interest income on securities available for sale is recorded on the accrual basis. Realized gains and losses for securities are included in investment securities gains (losses), net, on the consolidated statements of income and are derived using the specific identification method, on a trade date basis.

Loans and Interest Income on Loans

Loans are reported at principal amounts outstanding less amounts charged off, net of deferred fees and expenses. Interest income and deferred fees, net of expenses on loans, are recognized on a level yield basis.

Non-accrual Loans

Loans on which the accrual of interest has been discontinued are designated as non-accrual loans. Accrual of interest is discontinued on loans when reasonable doubt exists as to the full collection of interest or principal, or when loans become contractually past due for 90 days or more as to either interest or principal, in accordance with the terms of the loan agreement, unless they are both well-secured and in the process of collection. When a loan is placed on non-accrual status, previously accrued and uncollected interest is generally reversed as an adjustment to interest income on loans. Interest payments received on non-accrual loans are generally recorded as a reduction of principal. As payments are received on non-accruing loans, interest income can be recognized on a cash basis; however, there must be an expectation of full repayment of the remaining recorded principal balance. The remaining portion of this payment is recorded as a reduction to principal. Loans are generally returned to accruing status when they are brought fully current with respect to interest and principal and when, in the judgment of management, the loans are estimated to be fully collectible as to both principal and interest, and the borrower has sustained repayment performance under the terms of the loan agreement for a reasonable period of time (generally six months).

93

Impaired Loans

Impaired loans are loans for which it is probable that Synovus will not be able to collect all amounts due according to the contractual terms of the loan agreements and all loans modified in a troubled debt restructuring (TDR). Other than TDRs, impaired loans do not include smaller-balance homogeneous loans that are collectively evaluated for impairment, which consist of most retail loans and commercial loan relationships less than $1.0 million. Impairment is measured on a discounted cash flow method based upon the loan's contractual effective interest rate, or at the loan's observable market price, or at the fair value of the collateral, less costs to sell if the loan is collateral-dependent. Interest income on non-accrual impaired loans is recognized as described above under "non-accrual loans." Impaired accruing loans generally consist of those troubled debt restructurings for which management has concluded that the collectability of the loan is not in doubt.

At December 31, 2015, substantially all non-accrual impaired loans were collateral-dependent and secured by real estate. For impairment measured using the estimated fair value of collateral less costs to sell, fair value is estimated using appraisals performed by a certified or licensed appraiser. Management also considers other factors or recent developments, such as selling costs and anticipated sales values, taking into account management's plans for disposition, which could result in adjustments to the fair value estimates indicated in the appraisals. The assumptions used in determining the amount of the impairment are subject to significant judgment. Use of different assumptions, for example, changes in the fair value of the collateral or management's plans for disposition could have a significant impact on the amount of impairment.

Under the discounted cash flow method, impairment is recorded as a specific reserve with a charge-off for any portion of the impairment considered a confirmed loss. The reserve is reassessed each quarter and adjusted as appropriate based on changes in estimated cash flows.

Where guarantors are determined to be a source of repayment, an assessment of the guarantee is required. This guarantee assessment would include, but not be limited to, factors such as type and feature of the guarantee, consideration for the guarantor's financial strength and capacity to service the loan in combination with the guarantor's other financial obligations as well as the guarantor's willingness to assist in servicing the loan.

Troubled Debt Restructurings

When borrowers are experiencing financial difficulties, Synovus may, in order to assist the borrowers in repaying the principal and interest owed to Synovus, make certain modifications to the borrower's loan. All loan modifications and renewals are evaluated for troubled debt restructuring (TDR) classification. In accordance with ASU 2011-02, A Creditor's Determination of Whether a Restructuring is a Troubled Debt Restructuring, a TDR is defined as a modification with a borrower that is experiencing financial difficulties, and the creditor has granted a financial concession that it would not normally make. The market interest rate concept in ASU 2011-02 states that if a borrower does not otherwise have access to funds at a market interest rate for debt with characteristics similar to those of the restructured debt, the restructuring would be considered to be at a below-market rate, which indicates that the lender may have granted a concession. Since Synovus often increases or maintains the interest rate upon renewal of a commercial loan, including renewals of loans involving borrowers experiencing financial difficulties, the market rate concept has become a significant factor in determining if a loan is classified as a TDR. All TDRs are considered to be impaired loans, and the amount of impairment, if any, is determined in accordance with ASC 310-10-35, Accounting by Creditors for Impairment of a Loan-an amendment of FASB Statements No. 5, ASC 450-20, and No. 15, ASC 310-40.

Concessions provided by Synovus in a TDR are generally made in order to assist borrowers so that debt service is not interrupted and to mitigate the potential for loan losses. A number of factors are reviewed when a loan is renewed, refinanced, or modified, including cash flows, collateral values, guarantees, and loan structures. Concessions are primarily in the form of providing a below market interest rate given the borrower's credit risk to assist the borrower in managing cash flows, an extension of the maturity of the loan generally for less than one year, or a period of time generally less than one year with a reduction of required principal and/or interest payments (e.g., interest only for a period of time). These types of concessions may be made during the term of a loan or upon the maturity of a loan, as a loan renewal. Renewals of loans made to borrowers experiencing financial difficulties are evaluated for TDR designation by determining if concessions are being granted, including consideration of whether the renewed loan has an interest rate that is at market, given the credit risk related to the loan. Insignificant periods of reduction of principal and/or interest payments, or one time deferrals of three months or less, are generally not considered to be financial concessions. Further, it is generally Synovus' practice not to defer principal and/or interest for more than twelve months.

These types of concessions may be made during the term of a loan or upon the maturity of a loan, in which the borrower is experiencing financial difficulty, as a loan renewal.

Renewals of loans made to borrowers experiencing financial difficulties are evaluated for TDR designation by determining if concession(s) are being granted, including consideration of whether the renewed loan has an interest rate that is at market, given the credit risk related to the loan.

Non-accruing TDRs may generally be returned to accrual status if there has been a period of performance, usually at least a six month sustained period of repayment performance by the borrower. Consistent with regulatory guidance, a TDR will generally

94

no longer be reported as a TDR after a period of performance and after the loan was reported as a TDR at a year-end reporting date, and if at the time of the modification, the interest rate was at market, considering the credit risk associated with the borrower.

Allowance for Loan Losses

The allowance for loan losses is a significant accounting estimate that is determined through periodic and systematic detailed reviews of the Company’s loan portfolio. These reviews are performed to assess the probable incurred losses within the portfolio and to ensure consistency between fluctuations in the allowance and both credit events within the portfolio and prevailing credit trends. The economic and business climate in any given industry or market is difficult to gauge and can change rapidly, and the effects of those changes can vary by borrower. Significant judgments and estimates are necessary in the determination of the allowance for loan losses. Significant judgments include, among others, loan risk ratings and classifications, the determination and measurement of impaired loans, the timing of loan charge-offs, the probability of loan defaults, the net loss exposure in the event of loan defaults, the loss emergence period, qualitative loss factors, management’s plans, if any, for disposition of certain loans, as well as other qualitative considerations. In determining the allowance for loan losses, management makes numerous assumptions, estimates, and assessments, which are inherently subjective. The use of different estimates or assumptions could have a significant impact on the provision for loan losses, allowance for loan losses, non-performing loans, loan charge-offs and the Company's consolidated financial condition and results of operations.

The allocated allowance is based upon quarterly analyses of impaired commercial loans to determine the amount of specific reserves (and/or loan charge-offs), if any, as well as an analysis of historical loan default experience, loan net loss experience, loss emergence experience, and related qualitative factors, if appropriate, for categories of loans with similar risk attributes and further segregated by Synovus' internal loan grading system.

Impaired loans are generally evaluated on a loan by loan basis with specific reserves, if any, recorded as appropriate. Specific reserves are determined based on ASC 310-10-35, which provides for measurement of a loan's impairment based on one of three methods. If the loan is collateral-dependent, then the fair value of the loan's collateral, less estimated selling costs, are compared to the loan's carrying amount to determine impairment. Other methods of measuring a loan's impairment include the present value of the expected future cash flows of the loan, or if available, the observable market price of the loan. Synovus considers the pertinent facts and circumstances for each impaired loan when selecting the appropriate method to measure impairment, and quarterly evaluates each selection to ensure its continued appropriateness and evaluates the reasonableness of specific reserves, if any.

For loans that are not considered impaired, the allocated allowance for loan losses is determined based upon Expected Loss (EL) factors, which are applied to groupings of specific loan types by loan risk ratings. The EL is determined based upon a probability of default (PD), which is the probability that a borrower, segregated by loan type and loan risk grade, will default, and loss given default (LGD), which is the estimate of the amount of net loss in the event of default. The groupings of the loans into loan categories are determined based upon the nature of the loan types and the level of inherent risk associated with the various loan categories. The loan groupings are further segregated based upon the individual loan risk ratings, as described below. The EL factors applied in the methodology are periodically re-evaluated and adjusted to reflect changes in historical loss levels or other risks.

Allocated EL factors may also be adjusted, as necessary, for certain qualitative factors that in management's judgment are necessary to reflect losses incurred in the portfolio.

Qualitative factors that management considers in the analysis include:

• changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses

• changes in the volume and severity of past due loans, the volume of non-accrual loans, and the volume and severity of adversely classified or grade loans

• loan growth

• effects of changes in credit concentrations

• experience, ability, and depth of lending management, loan review personnel, and other relevant staff

• changes in the quality of the loan review function

• national and local economic trends and conditions

• value of underlying collateral for collateral-dependent loans

• other external factors such as the effects for the current competitive, legal, and regulatory environment

The adjusted EL factors by portfolio are then adjusted by a loss emergence period for each loan type. A loss emergence period represents the amount of time between when a loss event first occurs to when it is charged off. The loss emergence period was determined for each loan type based on the Company's historical experience and is validated annually.

95

Commercial Loans - Risk Ratings

Synovus utilizes two primary methods for risk assessment of the commercial loan portfolio: Single Risk Rating Assessment and Dual Risk Rating (DRR) Assessment. The single and dual risk ratings are based on the borrowers' credit risk profile, considering factors such as debt service history, current and estimated prospective cash flow information, collateral supporting the credit, source of repayment as well as other variables, as appropriate.

Each loan is assigned a risk rating during its initial approval process. For single risk rated loans, this process begins with a loan rating recommendation from the loan officer responsible for originating the loan. Commercial single risk rated loans are graded on a 9-point scale. Single risk ratings six through nine are defined consistent with the bank regulatory classifications of special mention, substandard, doubtful, and loss, respectively. The primary determinants of the risk ratings for commercial single risk rated loans are the reliability of the primary source of repayment and the borrower's expected performance (i.e., the likelihood that the borrower will be able to service its obligations in accordance with the terms). Expected performance will be based upon full analysis of the borrower's historical financial results, current financial strength and future prospects, which includes any external drivers.

For dual risk rated loans, this process begins with scoring the loan for a rating during its initial approval process. Synovus began utilizing a dual risk rating methodology for certain components of its commercial and industrial loan portfolio in 2013 and extended the DRR methodology to certain income-producing real estate loans in 2014 and 2015. The DRR includes sixteen probabilities of default categories and nine categories for estimating losses given an event of default. The result is an expected loss rate established for each borrower.

The loan rating is subject to approvals from other members of management, regional credit and/or loan committees depending on the size of the loan and loan's credit attributes. Loan ratings are regularly re-evaluated based upon annual scheduled credit reviews or on a more frequent basis if determined prudent by management.Additionally, an independent loan review function evaluates Synovus' risk rating processes on a continuous basis.

Management currently expects to implement the DRR methodology for additional components of the commercial loan portfolio over the next few years. The implementation is expected to be in multiple phases, with each component determined based primarily on loan type and size. The timing of future implementations will depend upon completion of applicable data analysis and model assessment. Once full implementation is completed, management estimates that the DRR methodology will be utilized to calculate the allowance for loan losses on commercial loans amounting to approximately 35% of the total loan portfolio. Approximately $6.7 billion, or 29.8%, of the total loan portfolio was rated using the DRR methodology at year-end 2015.

Retail Loans – Risk Ratings

Retail loans are generally assigned a risk rating on a 6-point scale at the time of origination based on credit bureau scores, with a loan grade of 1 assigned as the lowest level of risk and a loan grade of 6 as the highest level of risk. At 90-119 days past due, a loan grade of 7-substandard rating is applied and at 120 days past due, the loan is generally downgraded to grade 9-loss and is generally charged-off. The credit bureau-based ratings are updated at least semi-annually and the ratings based on the past due status are updated monthly.

Unallocated Allowance for Loan Losses

The unallocated component of the allowance for loan losses is not a significant component of the ALLL, but would be utilized to provide for certain environmental and economic factors that affect the inherent risk of loss in the entire loan portfolio that are not fully captured in the allocated allowance for loan losses. On a quarterly basis, management updates its analysis and consideration of these factors and determines the impact, if any, on the allowance for loan losses and the provision for loan losses for each respective period.

Premises and Equipment

Premises and equipment, including bank owned branch locations and leasehold improvements, are reported at cost, less accumulated depreciation and amortization, which are computed using the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are depreciated over the shorter of the estimated useful life or the remainder of the lease term. Synovus reviews long-lived assets, such as premises and equipment, for impairment whenever events and circumstances indicate that the carrying amount of an asset may not be recoverable.

Goodwill

Goodwill represents the excess purchase price over the fair value of identifiable net assets of acquired businesses. In accordance with ASC 350, Intangibles, Goodwill and Other, goodwill is not amortized, but tested for impairment at the reporting unit (sub-segment) level on an annual basis and as events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Synovus reviews goodwill for impairment as of June 30^th and at interim periods if indicators of impairment exist.

96

Significant judgment is applied when goodwill is assessed for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, incorporating general economic and market conditions, and selecting an appropriate control premium. The selection and weighting of the various fair value techniques may result in a higher or lower fair value. Judgment is applied in determining the weighting that are most representative of fair value.

Other Real Estate

Other Real Estate (ORE) consists of properties obtained through a foreclosure proceeding or through an in-substance foreclosure in satisfaction of loans. In accordance with the provisions of ASC 310-10-35 regarding subsequent measurement of loans for impairment and ASC 310-40-15 regarding accounting for troubled debt restructurings by a creditor, a loan is classified as an in-substance foreclosure when Synovus has taken possession of the collateral regardless of whether formal foreclosure proceedings have taken place.

At foreclosure, ORE is recorded at the lower of cost or fair value less estimated selling costs, which establishes a new cost basis. Subsequent to foreclosure, ORE is evaluated quarterly and reported at fair value less estimated selling costs, not to exceed the new cost basis, determined by review of current appraisals, as well as the review of comparable sales and other estimates of fair value obtained principally from independent sources, adjusted for estimated selling costs. Management also considers other factors or recent developments such as changes in absorption rates or market conditions from the time of the latest appraisal received or previous re-evaluation performed, and anticipated sales values considering management's plans for disposition, which could result in an adjustment to lower the fair value estimates indicated in the appraisals. At the time of foreclosure or initial possession of collateral, any excess of the loan balance over the fair value of the real estate held as collateral, less costs to sell, is recorded as a charge against the allowance for loan losses. Revenue and expenses from ORE operations as well as gains or losses on sales are recorded as foreclosed real estate expense, net, a component of non-interest expense on the consolidated statements of income. Subsequent declines in fair value are recorded on a property-by-property basis through use of a valuation allowance within other real estate on the consolidated balance sheets and valuation adjustment account in foreclosed real estate expense, net, a component of non-interest expense on the consolidated statements of income.

Synovus' objective is to dispose of ORE properties in a timely manner and to maximize net sale proceeds. Synovus has a centralized managed assets division, with the specialized skill set to facilitate this objective. While there is not a defined timeline for their sale, ORE properties are actively marketed through unaffiliated third parties.

Other Assets

Other assets include accrued interest receivable and other significant balances as described below.

Investments in Company-Owned Life Insurance Policies

Investments in company-owned life insurance policies on certain current and former officers of Synovus are recorded at the net realizable value of the policies as a component of other assets in the consolidated balance sheets. Net realizable value is the cash surrender value of the policies less any applicable surrender charges and any policy loans. Synovus has not borrowed against the cash surrender value of these policies. The changes in the cash surrender value of the policies is recognized as a component of other non-interest income in the consolidated statements of income.

Servicing Asset on SBA/Government Guaranteed Loans

Synovus has retained servicing responsibilities on sold SBA/government guaranteed loans and receives annual servicing fees on the outstanding loan balances.  SBA/government guaranteed loan servicing rights are accounted for using the amortization method.  A servicing asset is established at fair value at the time of the sale using a discounted future cash flow model.  The servicing asset is then amortized in other non-interest expense.

Private Equity Investments

Private equity investments are recorded at fair value on the consolidated balance sheets with realized and unrealized gains and losses recorded on the consolidated statements of income (as a component of other non-interest income) in accordance with ASC 946, Financial Services-Investment Companies. The private equity investments in which Synovus holds a limited partner interest consist of funds that invest in privately held companies. For privately held companies in the fund, the general partner estimates the fair value of the company in accordance with U.S. GAAP as clarified by ASC 820, Fair Value Measurements and Disclosures. The estimated fair value of the company is the estimated fair value as an exit price the fund would receive if it were to sell the company in the marketplace. The fair value of the fund's underlying investments is estimated through the use of valuation models, such as option pricing or a discounted cash flow model. Valuation factors, such as a company's financial performance against budget or milestones, last price paid by investors, with consideration given on whether financing is provided by insiders or unrelated new investors, public market comparables, liquidity of the market, industry and economic trends, and changes in management or key personnel, are used in the determination of estimated fair value.

97

Derivative Instruments

Synovus’ risk management policies emphasize the management of interest rate risk within acceptable guidelines. Synovus’ objective in maintaining these policies is to limit volatility in net interest income arising from changes in interest rates. Risks to be managed include both fair value and cash flow risks. Utilization of derivative financial instruments provides a valuable tool to assist in the management of these risks.

In accordance with ASC 815, Derivatives and Hedging, all derivative instruments are recorded on the consolidated balance sheets at their respective fair values, as components of other assets and other liabilities. The accounting for changes in fair value (i.e., unrealized gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and, if so, on the reason for holding it. If certain conditions are met, entities may elect to designate a derivative instrument as a hedge of exposures to changes in fair values, cash flows, or foreign currencies. If the hedged exposure is a fair value exposure, the unrealized gain or loss on the derivative instrument is recognized in earnings in the period of change, together with the offsetting unrealized loss or gain on the hedged item attributable to the risk being hedged as a component of other non-interest income on the consolidated statements of income. If the hedged exposure is a cash flow exposure, the effective portion of the gain or loss on the derivative instrument is reported initially as a component of accumulated other comprehensive income (loss), net of the tax impact, and subsequently reclassified into earnings when the hedged transaction affects earnings. Any amounts excluded from the assessment of hedge effectiveness, as well as the ineffective portion of the gain or loss on the derivative instrument, are reported in earnings immediately as a component of other non-interest income on the consolidated statements of income. If the derivative instrument is not designated as a hedge, the gain or loss on the derivative instrument is recognized in earnings as a component of other non-interest income on the consolidated statements of income in the period of change.

With the exception of certain commitments to fund and sell fixed-rate mortgage loans and derivatives utilized to meet the financing and interest rate risk management needs of its customers, all derivatives utilized by Synovus to manage its interest rate sensitivity are designated as either a hedge of a recognized fixed-rate asset or liability (fair value hedge), or a hedge of a forecasted transaction or of the variability of future cash flows of a floating rate asset or liability (cash flow hedge). Synovus does not speculate using derivative instruments.

In 2005, Synovus entered into certain forward starting swap contracts to hedge the cash flow risk of certain forecasted interest payments on a forecasted debt issuance. Upon the determination to issue debt, Synovus was potentially exposed to cash flow risk due to changes in market interest rates prior to the placement of the debt. The forward starting swaps allowed Synovus to hedge this exposure. Upon placement of the debt, these swaps were cash settled concurrent with the pricing of the debt. The effective portion of the cash flow hedge included in accumulated other comprehensive income is being amortized over the life of the debt issue as an adjustment to interest expense.

Synovus also holds derivative instruments, which consist of rate lock agreements related to expected funding of fixed-rate mortgage loans to customers (interest rate lock commitments) and forward commitments to sell mortgage-backed securities and individual fixed-rate mortgage loans. Synovus’ objective in obtaining the forward commitments is to mitigate the interest rate risk associated with the interest rate lock commitments and the mortgage loans that are held for sale. Both the interest rate lock commitments and the forward commitments are reported at fair value, with adjustments recorded in current period earnings in mortgage banking income.

Synovus also enters into interest rate swap agreements to facilitate the risk management strategies of certain commercial banking customers. Synovus mitigates this risk by entering into equal and offsetting interest rate swap agreements with highly rated third-party financial institutions. The interest rate swap agreements are free-standing derivatives and are recorded at fair value with any unrealized gain or loss recorded in current period earnings in other non-interest income. These instruments, and their offsetting positions, are recorded in other assets and other liabilities on the consolidated balance sheets.

When using derivatives to hedge fair value and cash flow risks, Synovus exposes itself to potential credit risk from the counterparty to the hedging instrument. This credit risk is generally a small percentage of the notional amount and fluctuates as interest rates change. Synovus analyzes and approves credit risk for all potential derivative counterparties prior to execution of any derivative transaction. Synovus seeks to minimize credit risk by dealing with highly rated counterparties and by obtaining collateralization for exposures above certain predetermined limits. If significant counterparty risk is determined, Synovus adjusts the fair value of the derivative recorded asset balance to consider such risk.

Non-interest Income

Service Charges on Deposit Accounts

Service charges on deposit accounts consist of non-sufficient funds fees, account analysis fees, and other service charges on deposits which consist primarily of monthly account fees. Non-sufficient funds fees are recognized at the time when the account overdraft occurs in accordance with regulatory guidelines. Account analysis fees consist of fees charged to certain commercial demand deposit accounts based upon account activity (and reduced by a credit which is based upon cash levels in the account). These fees, as well as monthly account fees, are recorded under the accrual method of accounting.

98

Fiduciary and Asset Management Fees

Fiduciary and asset management fees are generally determined based upon fair values of assets under management as of a specified date during the period. These fees are recorded under the accrual method of accounting as the services are performed.

Brokerage and Investment Banking Revenue

Brokerage revenue consists primarily of commission income, which represents the spread between buy and sell transactions processed, and net fees charged to customers on a transaction basis for buy and sell transactions processed. Commission income is recorded on a trade-date basis. Brokerage revenue also includes portfolio management fees, which represent monthly fees charged on a contractual basis to customers for the management of their investment portfolios and are recorded under the accrual method of accounting.

Investment banking revenue represents fees for services arising from securities offerings or placements in which Synovus acts as an agent. It also includes fees earned from providing advisory services. Revenue is recognized at the time the underwriting is completed and the revenue is reasonably determinable.

Bankcard Fees

Bankcard fees consist primarily of interchange fees earned, net of fees paid, on debit card and credit card transactions. Net fees are recognized into income as they are collected.

Advertising Costs

Advertising costs are expensed as incurred and recorded as a component of non-interest expense.

Income Taxes

Synovus is a domestic corporation that files a consolidated federal income tax return with its wholly-owned subsidiaries and files state income tax returns on a consolidated and a separate entity basis with the various taxing jurisdictions based on its taxable presence. Synovus accounts for income taxes in accordance with ASC 740, Income Taxes. The current income tax accrual or receivable is an estimate of the amounts owed to or due from taxing authorities in which Synovus conducts business. It also includes increases and decreases in the amount of taxes payable for uncertain tax positions reported in tax returns for the current and/or prior years.

Synovus uses the asset and liability method to account for future income taxes expected to be paid or received (i.e., deferred income taxes). Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement (GAAP) carrying amounts of existing assets and liabilities and their respective tax bases, including operating losses and tax credit carryforwards. The deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in income tax rates is recognized in income in the period that includes the enactment date.

A valuation allowance is required for deferred tax assets if, based on available evidence, it is more likely than not that all or some portion of the asset will not be realized. In making this assessment, all sources of taxable income available to realize the deferred tax asset are considered, including taxable income in prior carryback years, future reversals of existing temporary differences, tax planning strategies, and future taxable income exclusive of reversing temporary differences and carryforwards. The predictability that future taxable income, exclusive of reversing temporary differences, will occur is the most subjective of these four sources. Changes in the valuation allowance are recorded through income tax expense.

Significant estimates used in accounting for income taxes relate to the valuation allowance for deferred tax assets, estimates of the realizability of income tax credits, utilization of net operating losses, the determination of taxable income, and the determination of temporary differences between book and tax bases.

Synovus accrues tax liabilities for uncertain income tax positions based on current assumptions regarding the expected outcome by weighing the facts and circumstances available at the reporting date. If related tax benefits of a transaction are not more likely than not of being sustained upon examination, Synovus will accrue a tax liability or reduce a deferred tax asset for the expected tax impact associated with the transaction. Events and circumstances may alter the estimates and assumptions used in the analysis of its income tax positions and, accordingly, Synovus' effective tax rate may fluctuate in the future. Synovus recognizes accrued interest and penalties related to unrecognized income tax benefits as a component of income tax expense.

Share-based Compensation

Synovus has a long-term incentive plan under which the Compensation Committee of the Board of Directors has the authority to grant share-based awards to Synovus employees. Synovus' share-based compensation costs associated with employee grants are recorded as a component of salaries and other personnel expense in the consolidated statements of income. Share-based compensation costs associated with grants made to non-employee directors of Synovus are recorded as a component of other

99

operating expenses. Share-based compensation expense for service-based awards that contain a graded vesting schedule is recognized net of estimated forfeitures for plan participants on a straight-line basis over the requisite service period for the entire award.

Earnings per Share

Basic net income per common share is computed by dividing net income available to common shareholders by the average common shares outstanding for the period. Diluted net income per common share reflects the dilution that could occur if securities or other contracts to issue common stock were exercised or converted. The dilutive effect of outstanding options and restricted share units is reflected in diluted net income per common share, unless the impact is anti-dilutive, by application of the treasury stock method.

All share and per share amounts for all periods presented in this Report reflect the one-for-seven reverse stock split, which was effective on May 16, 2014.

Fair Value Measurements and Disclosures

Fair value estimates are made at a specific point in time, based on relevant market information and other information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale, at one time, the entire holdings of a particular financial instrument. Because no market exists for a portion of the financial instruments, fair value estimates are also based on judgments regarding estimated cash flows, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Synovus employs independent third-party pricing services to provide fair value estimates for its investment securities available for sale, trading account assets, and derivative financial instruments. Fair values for fixed income investment securities and certain derivative financial instruments are typically the prices supplied by either the third-party pricing service or an unrelated counterparty, which utilize quoted market prices, broker/dealer quotations for identical or similar securities, and/or inputs that are observable in the market, either directly or indirectly, for substantially similar securities. Level 1 securities are typically exchange quoted prices. Level 2 securities are typically matrix priced by a third-party pricing service to calculate the fair value. Such fair value measurements consider observable data, such as relevant broker/dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayments speeds, credit information, and the respective terms and conditions for debt instruments. Level 3 instruments' value is determined using pricing models, discounted cash flow models and similar techniques, and may also include the use of market prices of assets or liabilities that are not directly comparable to the subject asset or liability. These methods of valuation may result in a significant portion of the fair value being derived from unobservable assumptions that reflect Synovus' own estimates for assumptions that market participants would use in pricing the asset or liability.

Management uses various validation procedures to validate the prices received from pricing services and quotations received from dealers are reasonable for each relevant financial instrument, including reference to relevant broker/dealer quotes or other market quotes and a review of valuations and trade activity of comparable securities. Consideration is given to the nature of the quotes (e.g., indicative or firm) and the relationship of recently evidenced market activity to the prices provided by the third-party pricing service. Further, management also employs the services of an additional independent pricing firm as a means to verify and confirm the fair values of its primary independent pricing firm.

Understanding the third-party pricing service's valuation methods, assumptions and inputs used by the firm is an important part of the process of determining that reasonable and reliable fair values are being obtained. Management evaluates quantitative and qualitative information provided by the third-party pricing services to assess whether they continue to exhibit the high level of expertise and internal controls that management relies upon.

Fair value estimates are based on existing financial instruments on the consolidated balance sheet, without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Significant assets and liabilities that are not considered financial instruments include deferred income taxes, premises and equipment, equity method investments, goodwill and other intangible assets. In addition, the income tax ramifications related to the realization of the unrealized gains and losses on available for sale investment securities and cash flow hedges can have a significant effect on fair value estimates and have not been considered in any of the estimates.

Contingent Liabilities and Legal Costs

Synovus estimates its contingent liabilities with respect to outstanding legal matters based on information currently available to management, management’s estimates about the probability of outcomes of each case and the advice of legal counsel. In accordance with guidance in ASC 450-25-2, management accrues an estimated loss from a loss contingency when information available indicates that it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. In addition, it must be probable that one or more future events will occur confirming the fact of the loss. Significant judgment is

100

required in making these estimates and management must make assumptions about matters that are highly uncertain. Accordingly, the actual loss may be more or less than the current estimate.

In many situations, Synovus may be unable to estimate reasonably possible losses due to the preliminary nature of the legal matters, as well as a variety of other factors and uncertainties. As there are further developments, Synovus will reassess these legal matters and the related potential liabilities and will revise, when needed, its estimate of contingent liabilities.

Legal costs, including attorney fees, incurred in connection with pending litigation and other loss contingencies are expensed as incurred.

Recently Adopted Accounting Standards Updates

In January 2014, the FASB issued amended guidance, ASU 2014-01, Investments-Equity Method and Joint Ventures (Topic 323), Accounting for Investments in Qualified Affordable Housing Projects, which permits Synovus to make an accounting policy election to account for its investments in qualified affordable housing projects using a proportional amortization method, if certain conditions are met, and to present the amortization as a component of income tax expense. The amended guidance would be applied retrospectively to all periods presented and is effective for fiscal years, and interim periods within those years, beginning after December 15, 2014. Regardless of the policy election, the amended guidance, where disclosed, enables users of the financial statements to understand the nature of investments in qualified affordable housing projects and the effect of the measurement of the investments in qualified affordable housing projects and the related tax credits on Synovus' financial position and results of operations.

Synovus adopted the amended guidance on January 1, 2015, and did not make an accounting policy election to apply the proportional amortization method for its investments in qualified affordable housing projects because the impact to the consolidated financial statements was insignificant. Therefore, the adoption did not have an impact on Synovus' consolidated financial statements. At December 31, 2015, the aggregate carrying value of Synovus' investments in LIHTC partnerships was $18.9 million. See Note 16 "Variable Interest Entities" to the consolidated financial statements of Synovus' 2015 Form 10-K for additional information regarding these investments.

Synovus early adopted ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs, during the the fourth quarter of 2015. This ASU was issued to simplify the presentation of debt issuance costs. Under previous accounting standards, debt issuance costs were reported on the balance sheet as assets and amortized as interest expense. ASU 2015-03 requires that debt issuance costs be presented on the balance sheet as a direct deduction from the carrying amount of the related liability, which is similar to the presentation of debt discounts or premiums. The costs will continue to be amortized to interest expense using the effective interest method. The cost of issuing debt will no longer be recorded as a separate asset, except when incurred before receipt of the funding from the associated debt liability. All prior periods presented in this Report have been adjusted to reflect adoption of ASU 2015-03 with updates to long-term debt and other assets. Adoption of ASU 2015-03 did not have a material impact on Synvous' consolidated financial statements.

Additionally, adoption of the following standards effective January 1, 2015, did not have a significant impact on Synovus' consolidated financial statements:

•ASU 2014-14, Classification of Certain Government-Guaranteed Mortgage Loans Upon Foreclosure

•ASU 2014-12, Accounting for Share-Based Payments when the Terms of an Award Provide that a Performance

Target Could be Achieved after the Requisite Service Period

•ASU 2014-11, Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures

•ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity

•ASU 2014-04, Receivables-Troubled Debt Restructurings by Creditors (Subtopic 310-40), Reclassification of

Residential Real Estate Collateralized Consumer Mortgage Loans Upon Foreclosure

ŸASU 2015-05, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-

Credit Arrangements

Recently Issued Accounting Standards Updates

The following ASUs will be implemented effective January 1, 2016 or later:

ASU 2014-09, "Revenue from Contracts with Customers" - ASU 2014-09 establishes a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The standard is intended to increase comparability across industries and jurisdictions. The core principle of the revenue model is that a company will recognize revenue when it transfers control of goods or services to customers at an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services.

101

The FASB issued ASU 2015-14, Revenue From Contracts with Customers – Deferral of the Effective Date, in August 2015 to defer the effective date of ASU 2014-09 for one year. The proposed new effective date will be annual reporting periods beginning after December 15, 2017, and interim periods within that year, for public business entities. As such, for Synovus, the ASU will be effective on January 1, 2018. Earlier application will be permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period.

Management is currently evaluating the impact of ASU 2014-09 on Synovus' consolidated financial statements. The standard is expected to potentially impact ORE sales, interchange revenue, credit card loyalty programs, uncollectible credit card interest and fees, asset managers’ performance fees, treasury management services revenue, and miscellaneous fees; however the overall

financial statement impact for Synovus is not expected to be material. Extensive new disclosures will be required, including disaggregation of total revenue, information about performance obligations, changes in contract asset and liability account balances

between periods, and information about key judgments and estimates and policy decisions regarding revenue recognition.

ASU 2015-02, "Amendments to the Consolidation Analysis" - ASU 2015-02 was issued by the FASB to modify the analysis that companies must perform in order to determine whether a legal entity should be consolidated. ASU 2015-02 simplifies current consolidation rules by reducing the number of consolidation models; placing more emphasis on risk of loss when determining a controlling financial interest; reducing the frequency of the application of related-party guidance when determining a controlling financial interest in a variable interest entity (VIE); and changing consolidation conclusions for public and private companies in several industries that typically make use of limited partnerships or VIEs. ASU 2015-02 will be effective for the first quarter of 2016 for Synovus. Management does not expect the adoption of this ASU to have a material impact on the consolidated financial statements of Synovus.

Reclassifications

Prior years' consolidated financial statements are reclassified whenever necessary to conform to the current year's presentation.

Subsequent Events

Synovus has evaluated for consideration, or disclosure, all transactions, events, and circumstances, subsequent to the date of the consolidated balance sheet and through the date the accompanying audited consolidated financial statements were issued, and has reflected, or disclosed, those items deemed appropriate within the consolidated financial statements and related footnotes.

Note 2 - Sale of Branches

On January 17, 2014, Synovus completed the sale of certain loans, premises, deposits, and other assets and liabilities of the Memphis, Tennessee branches of Trust One Bank, a division of Synovus Bank.  The sale included $89.6 million in total loans and $191.3 million in total deposits.   Results for the year ended December 31, 2014 reflect a pre-tax gain, net of associated costs, of $5.8 million relating to this transaction.  

Note 3 - Restructuring Charges

For the years ended December 31, 2015, 2014, and 2013 total restructuring charges consist of the following components:

	Years Ended December 31,
(in thousands)	2015			2014		2013
Severance charges	$	—		7,246		8,046
Lease termination charges	(3		)	4,808		1,060

Professional fees and other charges	211			1,767		63
Total restructuring charges	$	36		20,585		11,064

For the year ended December 31, 2015, Synovus recorded net gains of $401 thousand on the sale of certain branch locations and recorded additional expense, net of $437 thousand associated primarily with the 2014 branch closings. Restructuring charges for the year ended December 31, 2014 related primarily to expense savings initiatives that were approved during 2014. The initiatives included the consolidation or closing of certain branch locations as well as workforce reductions.   Asset impairment and lease termination charges for the year ended December 31, 2014 consisted primarily of charges related to the closure of 13 branches during the fourth quarter of 2014.   Severance charges for the year ended December 31, 2014 consisted of estimated involuntary termination benefits for targeted staff reductions identified during 2014. These termination benefits were provided under an ongoing benefit arrangement as defined in ASC 712, Compensation-Nonretirement Postemployment Benefits; accordingly, the charges were recorded pursuant to the liability recognition criteria of ASC 712.   Additionally, substantially all of the professional

102

fees and other charges for the year ended December 31, 2014 consisted of professional fees incurred in connection with an organizational restructuring implemented during 2014.

Restructuring charges for the year ended December 31, 2013 related primarily to expense savings initiatives approved during 2013 which consisted primarily of the consolidation or closing of certain branch locations as well as workforce reductions. The involuntary termination benefits relating to these workforce reductions were provided under a one-time benefit arrangement as defined in ASC 420, Exit or Disposal Costs or Obligations; accordingly, the charges were recorded pursuant to the liability recognition criteria of ASC 420.

The following table presents aggregate activity associated with accruals that resulted from the restructuring charges recorded during the years ended December 31, 2015, 2014, and 2013:

⁽¹⁾  Amortized cost is adjusted for other-than-temporary impairment charges in 2014, which have been recognized in the consolidated statements of income, and were considered inconsequential.

At December 31, 2015 and 2014, investment securities with a carrying value of $2.43 billion and $2.12 billion, respectively, were pledged to secure certain deposits and securities sold under repurchase agreements as required by law and contractual agreements.

Synovus has reviewed investment securities that are in an unrealized loss position as of December 31, 2015 and 2014 for OTTI and does not consider any securities in an unrealized loss position to be other-than-temporarily impaired. If Synovus intended to sell a security in an unrealized loss position, the entire unrealized loss would be reflected in income. Synovus does not intend to sell investment securities in an unrealized loss position prior to the recovery of the unrealized loss, which may be until maturity, and has the ability and intent to hold those securities for that period of time. Additionally, Synovus is not currently aware of any circumstances which will require it to sell any of the securities that are in an unrealized loss position prior to the respective securities recovery of all such unrealized losses.

104

Declines in the fair value of available for sale securities below their cost that are deemed to have OTTI are reflected in earnings as realized losses to the extent the impairment is related to credit losses. The amount of the impairment related to other factors is recognized in other comprehensive income. Currently, unrealized losses on debt securities are attributable to increases in interest rates on comparable securities from the date of purchase. Synovus regularly evaluates its investment securities portfolio to ensure that there are no conditions that would indicate that unrealized losses represent OTTI. These factors include the length of time the security has been in a loss position, the extent that the fair value is below amortized cost, and the credit standing of the issuer. As of December 31, 2015, Synovus had sixty-four investment securities in a loss position for less than twelve months and twenty-nine investment securities in a loss position for twelve months or longer.

Gross unrealized losses on investment securities and the fair value of the related securities, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, at December 31, 2015 and December 31, 2014 are presented below.

The amortized cost and fair value by contractual maturity of investment securities available for sale at December 31, 2015 are shown below. The expected life of mortgage-backed securities or CMOs may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. For purposes of the maturity table, mortgage-backed securities and CMOs, which are not due at a single maturity date, have been classified based on the final contractual maturity date.

Non-accrual loans as of December 31, 2015 and 2014 were $168.4 million and $197.8 million, respectively. Interest income on non-accrual loans outstanding at December 31, 2015 and 2014 that would have been recorded if the loans had been current and performed in accordance with their original terms was $10.5 million and $12.6 million, respectively. Interest income recorded on these loans for the years ended December 31, 2015 and 2014 was $4.3 million and $4.1 million, respectively.

The credit quality of the loan portfolio is summarized no less frequently than quarterly using the standard asset classification system utilized by the federal banking agencies. These classifications are divided into three groups – Not Classified (Pass), Special Mention, and Classified or Adverse rating (Substandard, Doubtful, and Loss) and are defined as follows:

Pass- loans which are well protected by the current net worth and paying capacity of the obligor (or guarantors, if any) or by the fair value, less cost to acquire and sell, of any underlying collateral in a timely manner.

Special Mention - loans which have potential weaknesses that deserve management's close attention. These loans are not adversely classified and do not expose an institution to sufficient risk to warrant an adverse classification.

Substandard - loans which are inadequately protected by the current net worth and paying capacity of the obligor or by the collateral pledged, if any. Loans with this classification are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.

Doubtful - loans which have all the weaknesses inherent in loans classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full highly questionable and improbable on the basis of currently known facts, conditions, and values.

Loss - loans which are considered by management to be uncollectible and of such little value that its continuance on the institution's books as an asset, without establishment of a specific valuation allowance or charge-off is not warranted.

\

109

In the following tables, retail loans are classified as Pass except when they reach 90 days past due or are downgraded to substandard, and upon reaching 120 days past due, they are downgraded to loss and charged off, in accordance with the FFIEC Uniform Retail Credit Classification and Account Management Policy. The risk grade classifications of retail loans secured by junior liens on 1-4 family residential properties also consider available information on the payment status of the associated senior lien with other financial institutions.

The average recorded investment in impaired loans was $952.3 million for the year ended December 31, 2013. Excluding accruing TDRs, there was no interest income recognized for the investment in impaired loans for the years ended December 31, 2015 , 2014, and 2013. Interest income recognized for accruing TDRs was $21.1 million for the year ended December 31, 2013. At December 31, 2015, 2014, and 2013, all impaired loans, other than $223.9 million, $348.4 million, and $556.4 million, respectively, of accruing TDRs, were on nonaccrual status.

113

Concessions provided in a TDR are primarily in the form of providing a below market interest rate given the borrower's credit risk, a period of time generally less than one year with a reduction of required principal and/or interest payments (e.g., interest only for a period of time), or extension of the maturity of the loan generally for less than one year. Insignificant periods of reduction of principal and/or interest payments, or one time deferrals of three months or less, are generally not considered to be financial concessions.

The following tables represent the post-modification balance, shown by type of concession, for loans modified or renewed during the years ended December 31, 2015 and 2014 that were reported as accruing or non-accruing TDRs.

If at the time that a loan was designated as a TDR the loan was not already impaired, the measurement of impairment resulting from the TDR designation changes from a general pool-level reserve to a specific loan measurement of impairment in accordance with ASC 310-10-35, Accounting By Creditors for Impairment of a Loan—an amendment of FASB Statements No. 5, ASC 450-20, and No. 15, ASC 310-40. Generally, the change in the allowance for loan losses resulting from such a TDR is not significant. At December 31, 2015, the allowance for loan losses allocated to accruing TDRs totaling $223.9 million was $12.6 million compared to accruing TDR's of $348.4 million with a related allowance for loan losses of $21.0 million at December 31, 2014. Nonaccrual non-homogeneous loans (commercial-type impaired loan relationships greater than $1 million) that are designated as TDRs are individually measured for the amount of impairment, if any, both before and after the TDR designation.

In the ordinary course of business, Synovus Bank has made loans to certain Synovus and Synovus Bank executive officers and directors (including their associates and affiliates). Management believes that such loans are made on the same terms, including interest rate and collateral, as those prevailing at the time for comparable transactions with unaffiliated customers.

The following is a summary of such loans and the activity in these loans for the year ended December 31, 2015.

In accordance with ASC 740-20-45-11(b), a deferred tax asset valuation allowance associated with unrealized gains and losses not recognized in income is charged directly to other comprehensive income (loss). During the years 2010 and 2011, Synovus recorded a deferred tax asset valuation allowance associated with unrealized gains and losses not recognized in income directly to other comprehensive income (loss) by applying the portfolio approach for allocation of the valuation allowance. Synovus has consistently applied the portfolio approach which treats derivative instruments, equity securities, and debt securities as a single portfolio. As of December 31, 2015, the ending balance in net unrealized gains (losses) on cash flow hedges and net unrealized gains (losses) on investment securities available for sale includes unrealized losses of $12.1 million and $13.3 million, respectively, related to the residual tax effects remaining in OCI due to the previously established deferred tax asset valuation allowance. Under the portfolio approach, these unrealized losses are realized at the time the entire portfolio is sold or disposed.

Reverse Stock Split and Increase in Number of Authorized Common Shares

121

On April 24, 2014, at Synovus' 2014 annual shareholders' meeting, Synovus’ shareholders approved a proposal authorizing Synovus’ Board of Directors to effect a one-for-seven reverse stock split of Synovus’ common stock. Following this annual meeting, Synovus’ Board of Directors authorized the one-for-seven reverse stock split. The reverse stock split became effective on May 16, 2014, and Synovus' shares of common stock began trading on a post-split basis on the NYSE at the opening of trading on May 19, 2014. All prior periods presented in this Report have been adjusted to reflect the one-for-seven reverse stock split. Financial information updated by this capital change includes earnings per common share, dividends per common share, stock price per common share, weighted average common shares, outstanding common shares, treasury shares, common stock, additional paid-in capital, and share-based compensation.

Additionally, at Synovus' 2014 annual shareholders' meeting, Synovus’ shareholders approved an amendment to the articles of incorporation to increase the number of authorized shares of Synovus’ common stock from 1.2 billion shares to 2.4 billion shares. Synovus effected the increase in the number of authorized shares on April 24, 2014. Upon the reverse stock split effective date, the number of Synovus’ authorized shares of common stock was proportionately reduced from 2.4 billion shares to 342.9 million shares.

Note 12 - Regulatory Capital

Synovus is subject to regulatory capital requirements administered by the federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, Synovus must meet specific capital levels that involve quantitative measures of both on- and off-balance sheet items as calculated under regulatory capital guidelines. Capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.

The Basel III capital rules, implemented in the U.S. with certain changes mandated by the Dodd-Frank Act, strengthen the definition of regulatory capital, increase risk-based capital requirements, and make selected changes to the calculation of risk-weighted assets. The rules became effective January 1, 2015, for Synovus and Synovus Bank, subject to a transition period for several aspects, including the capital conservation buffer and certain regulatory capital adjustments and deductions, as described below. Under the Basel III capital rules, the minimum capital requirements for Synovus and Synovus Bank include a common equity Tier 1 (CET1) ratio of 4.5%; Tier 1 capital ratio of 6%; total capital ratio of 8%; and leverage ratio of 4%. When fully phased-in on January 1, 2019, the Basel III capital rules include a capital conservation buffer of 2.5% that is added on top of each of the minimum risk-based capital ratios. The implementation of the capital conservation buffer will begin on January 1, 2016 at the 0.625% level and be phased-in over a three-year period (increasing by that amount on each subsequent January 1, until it reaches 2.5% on January 1, 2019). As a financial holding company, Synovus and its subsidiary bank, Synovus Bank, are required to maintain capital levels required for a well-capitalized institution as defined by federal banking regulations. Under the Basel III capital rules, Synovus and Synovus Bank are well-capitalized if each has a CET1 ratio of 6.5% or greater, a Tier 1 risk-based capital ratio of 8% or greater, a total risk-based capital ratio of 10% or greater, a leverage ratio of 5% or greater, and are not subject to any written agreement, order, capital directive, or prompt corrective action directive from a federal and/or state banking regulatory agency to meet and maintain a specific capital level for any capital measure.

Management currently believes, based on internal capital analyses and earnings projections, that Synovus' capital position is adequate to meet current and future regulatory minimum capital requirements.

For the years ended December 31, 2015, 2014, and 2013, there were 2.8 million, 3.3 million, and 3.8 million potentially dilutive shares, respectively, related to common stock options and Warrants to purchase shares of common stock that were outstanding during 2015, 2014, and 2013, respectively, but were not included in the computation of diluted net income per common share because the effect would have been anti-dilutive.

Note 14 - Fair Value Accounting

Synovus carries various assets and liabilities at fair value based on the fair value accounting guidance under ASC 820, Fair Value Measurements, and ASC 825, Financial Instruments. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an “exit price”) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

Synovus has implemented controls and processes for the determination of the fair value of financial instruments. The ultimate responsibility for the determination of fair value rests with Synovus. Synovus has established a process that has been designed to ensure there is an independent review and validation of fair values by a function independent of those entering into the transaction. This includes specific controls to ensure consistent pricing policies and procedures that incorporate verification for both market and derivative transactions. For all financial instruments where fair values are determined by reference to externally quoted prices or observable pricing inputs to models, independent price determination or validation is utilized. Where the market for a financial instrument is not active, fair value is determined using a valuation technique or pricing model. These valuation techniques and models involve a degree of estimation, the extent of which depends on each instrument's complexity and the availability of market-based data.

The most frequently applied pricing model and valuation technique utilized by Synovus is the discounted cash flow model. Discounted cash flows determine the value by estimating the expected future cash flows from assets or liabilities discounted to their present value. Synovus may also use a relative value model to determine the fair value of a financial instrument based on the market prices of similar assets or liabilities or an option pricing model such as binomial pricing that includes probability-based techniques. Assumptions and inputs used in valuation techniques and models include benchmark interest rates, credit spreads and other inputs used in estimating discount rates, bond and equity prices, price volatilities and correlations, prepayment rates, probability of default, and loss severity upon default.

Synovus refines and modifies its valuation techniques as markets develop and as pricing for individual financial instruments become more or less readily available. While Synovus believes its valuation techniques are appropriate and consistent with other market participants, the use of different methodologies or assumptions could result in different estimates of fair value at the balance sheet date. In order to determine the fair value, where appropriate, management applies valuation adjustments to the pricing information. These adjustments reflect management's assessment of factors that market participants would consider in setting a price, to the extent that these factors have not already been included in the pricing information. Furthermore, on an ongoing basis, management assesses the appropriateness of any model used. To the extent that the price provided by internal models does not represent the fair value of the financial instrument, management makes adjustments to the model valuation to calibrate it to other available pricing sources. Where unobservable inputs are used, management may determine a range of possible valuations based upon differing stress scenarios to determine the sensitivity associated with the valuation. As a final step, management considers the need for further adjustments to the modeled price to reflect how market participants would price the financial instrument.

123

Fair Value Hierarchy

Synovus determines the fair value of its financial instruments based on the fair value hierarchy established under ASC 820-10, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the financial instrument's fair value measurement in its entirety. There are three levels of inputs that may be used to measure fair value. The three levels of inputs of the valuation hierarchy are defined below:

Level 1	Quoted prices (unadjusted) in active markets for identical assets and liabilities for the instrument or security to be valued. Level 1 assets include marketable equity securities, Treasury securities, and mutual funds.
Level 2	Observable inputs other than Level 1 quoted prices, such as quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active or model-based valuation techniques for which all significant assumptions are derived principally from or corroborated by observable market data. Level 2 assets and liabilities include debt securities with quoted prices that are traded less frequently than exchange-traded instruments and derivative contracts whose value is determined by using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data. U.S. Government sponsored agency securities, mortgage-backed securities issued by GSEs and agencies, obligations of states and municipalities, collateralized mortgage obligations issued by GSEs, and mortgage loans held for sale are generally included in this category. Certain private equity investments that invest in publicly traded companies are also considered Level 2 assets.
Level 3	Unobservable inputs that are supported by little, if any, market activity for the asset or liability. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow models and similar techniques, and may also include the use of market prices of assets or liabilities that are not directly comparable to the subject asset or liability. These methods of valuation may result in a significant portion of the fair value being derived from unobservable assumptions that reflect Synovus' own estimates for assumptions that market participants would use in pricing the asset or liability. This category primarily consists of collateral-dependent impaired loans, other real estate, certain equity investments, and private equity investments.

Fair Value Option

Synovus has elected the fair value option for mortgage loans held for sale primarily to ease the operational burdens required to maintain hedge accounting for these loans. Synovus is still able to achieve effective economic hedges on mortgage loans held for sale without the time and expense needed to manage a hedge accounting program.

Valuation Methodology by Product

Following is a description of the valuation methodologies used for the major categories of financial assets and liabilities measured at fair value.

Trading Account Assets and Investment Securities Available for Sale

The fair values of trading securities and investment securities available for sale are primarily based on actively traded markets where prices are based on either quoted market prices or observed transactions. Management employs independent third-party pricing services to provide fair value estimates for Synovus' investment securities available for sale and trading securities. Fair values for fixed income investment securities are typically determined based upon quoted market prices, broker/dealer quotations for identical or similar securities, and/or inputs that are observable in the market, either directly or indirectly, for substantially similar securities. Level 1 securities are typically exchange quoted prices and include financial instruments such as U.S. Treasury securities, marketable equity securities, and mutual fund investments. Level 2 securities are typically matrix priced by the third-party pricing service to calculate the fair value. Such fair value measurements consider observable data such as relevant broker/dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayments speeds, credit information, and the respective terms and conditions for debt instruments. The types of securities classified as Level 2 within the valuation hierarchy primarily consist of collateralized mortgage obligations, mortgage-backed securities, debt securities of GSEs and agencies, corporate debt, and state and municipal securities.

When there is limited activity or less transparency around inputs to valuation, Synovus develops valuations based on assumptions that are not readily observable in the marketplace; these securities are classified as Level 3 within the valuation hierarchy. The majority of the balance of Level 3 investment securities available for sale consists primarily of trust preferred securities issued by financial institutions. Synovus also carries non-marketable common equity securities within this category. Synovus accounts for the non-marketable common equity securities in accordance with ASC 325-20, Investments-Other-Cost Method Investments, which requires these investments to be carried at cost. To determine the fair value of the trust preferred securities, management uses a measurement technique to reflect one that utilizes credit spreads and/or credit indices available from a third-party pricing service.  In addition, for each trust preferred security, management projects non-credit adjusted cash flows, and discounts those cash flows to net present value incorporating a relevant credit spread in the discount rate.  Other inputs to calculating fair value include potential discounts for lack of marketability.

124

Management uses various validation procedures to confirm the prices received from pricing services and quotations received from dealers are reasonable. Such validation procedures include reference to relevant broker/dealer quotes or other market quotes and a review of valuations and trade activity of comparable securities. Consideration is given to the nature of the quotes (e.g., indicative or firm) and the relationship of recently evidenced market activity to the prices provided by the third-party pricing service. Further, management also employs the services of an additional independent pricing firm as a means to verify and confirm the fair values of the primary independent pricing firms.

Mortgage Loans Held for Sale

Synovus elected to apply the fair value option for mortgage loans originated with the intent to sell to investors. When loans are not committed to an investor at a set price, fair value is derived from a hypothetical bulk sale model used to estimate the exit price of the loans in a loan sale. The bid pricing convention is used for loan pricing for similar assets. The valuation model is based upon forward settlements of a pool of loans of similar coupon, maturity, product, and credit attributes. The inputs to the model are continuously updated with available market and historical data. As the loans are sold in the secondary market and primarily used as collateral for securitizations, the valuation model represents the highest and best use of the loans in Synovus’ principal market. Mortgage loans held for sale are classified within Level 2 of the valuation hierarchy.

Private Equity Investments

Private equity investments consist primarily of equity method investments in venture capital funds, which are classified as Level 3 within the valuation hierarchy. The valuation of these investments requires significant judgment due to the absence of quoted market prices, inherent lack of liquidity, and the long-term nature of such investments. Based on these factors, the ultimate realizable value of these investments could differ significantly from the value reflected in the accompanying audited consolidated financial statements. For ownerships in publicly traded companies held in the funds, valuation is based on the closing market price at the balance sheet date, with such investments being classified as Level 1 or 2 within the valuation hierarchy. The valuation of marketable securities that have trading restrictions is discounted until the securities can be freely traded. The private equity investments in which Synovus holds a limited partnership interest consist of funds that invest in privately held companies. For privately held companies in the funds, the general partner estimates the fair value of the company in accordance with GAAP, as clarified by ASC 820, and guidance specific to investment companies. The estimated fair value of the company is the estimated fair value as an exit price the fund would receive if it were to sell the company in the marketplace. The fair value of the fund's underlying investments is estimated through the use of valuation models such as option pricing or a discounted cash flow model. Valuation factors, such as a company's operational performance against budget or milestones, last price paid by investors, with consideration given on whether financing is provided by insiders or unrelated new investors, public market comparables, liquidity of the market, industry and economic trends, and changes in management or key personnel, are used in the determination of fair value.

Also, Synovus holds an interest in an investment fund that invests in publicly traded financial services companies. Although the fund holds investments in publicly traded entities, the fair value of this investment is classified as Level 2 in the valuation hierarchy because there is no actively traded market for the fund itself, and the value of the investment is based on the aggregate fair value of the publicly traded companies that are held in the fund for investment.

Mutual Funds Held in Rabbi Trusts

Mutual funds held in rabbi trusts primarily invest in equity and fixed income securities. Shares of mutual funds are valued based on quoted market prices, and are therefore classified within Level 1 of the fair value hierarchy.

Salary Stock Units

Salary stock units represent fully vested stock awards that have been granted to certain key employees of Synovus. The salary stock units are classified as liabilities and are settled in cash, as determined by the average closing common stock price on the 20 trading days preceding the date of settlement and the number of salary stock units being settled. Accordingly, salary stock units are classified as Level 1 within the fair value hierarchy.

125

Derivative Assets and Liabilities

As part of its overall interest rate risk management activities, Synovus utilizes derivative instruments to manage its exposure to various types of interest rate risk. With the exception of one derivative contract discussed herein, Synovus' derivative financial instruments are all Level 2 financial instruments. The majority of derivatives entered into by Synovus are executed over-the-counter and consist of interest rate swaps. The fair values of these derivative instruments are determined based on an internally developed model that uses readily observable market data, as quoted market prices are not available for these instruments. The valuation models and inputs depend on the type of derivative and the nature of the underlying instrument, and include interest rates, prices and indices to generate continuous yield or pricing curves, volatility factors, and customer credit related adjustments. The principal techniques used to model the value of these instruments are an income approach, discounted cash flows, and Black-Scholes or binomial pricing models. The sale of TBA mortgage-backed securities for current month delivery or in the future and the purchase of option contracts of similar duration are derivatives utilized by Synovus, and are valued by obtaining prices directly from dealers in the form of quotes for identical securities or options using a bid pricing convention with a spread between bid and offer quotations. Interest rate swaps, floors, caps and collars, and TBA mortgage-backed securities are classified as Level 2 within the valuation hierarchy.

Synovus enters into interest rate lock commitments related to expected funding of residential mortgage loans at specified times in the future. Interest rate lock commitments that relate to the origination of mortgage loans that will be held-for-sale are considered derivative instruments under applicable accounting guidance. As such, Synovus records its interest rate lock commitments and forward loan sales commitments at fair value, determined as the amount that would be required to settle each of these derivative financial instruments at the balance sheet date. In the normal course of business, Synovus enters into contractual interest rate lock commitments to extend credit at a fixed interest rate and with fixed expiration dates. The commitments become effective when the borrowers "lock-in" a specified interest rate within the established time frames. Market risk arises if interest rates move adversely between the time of the interest rate lock by the borrower and the sale date of the loan to an investor. To mitigate the effect of the interest rate risk inherent in providing interest rate lock commitments to borrowers, Synovus enters into best efforts forward sales contracts with third-party investors. The forward sales contracts lock in a price for the sale of loans similar to the specific interest rate lock commitments. Both the interest rate lock commitments to the borrowers and the forward sales contracts to the investors are derivatives, and accordingly, are marked to fair value through earnings. In estimating the fair value of an interest rate lock commitment, Synovus assigns a probability to the interest rate lock commitment based on an expectation that it will be exercised and the loan will be funded. The fair value of the interest rate lock commitment is derived from the fair value of related mortgage loans, which is based on observable market data and includes the expected net future cash flows related to servicing of the loans. The fair value of the interest rate lock commitment is also derived from inputs that include guarantee fees negotiated with the agencies and private investors, buy-up and buy-down values provided by the agencies and private investors, and interest rate spreads for the difference between retail and wholesale mortgage rates. Management also applies fall-out ratio assumptions to the interest rate lock commitments in anticipation of those mortgage loans which will not close. The fall-out ratio assumptions are based on Synovus' historical experience, conversion ratios for similar loan commitments, and market conditions. While fall-out tendencies are not exact predictions of which loans will or will not close, historical performance review of loan-level data provides the basis for determining the appropriate hedge ratios. In addition, on a periodic basis, Synovus performs analyses of actual rate lock fall-out experience to determine the sensitivity of the mortgage pipeline to interest rate changes from the date of the commitment through loan origination. The expected fall-out ratios (or conversely the "pull-through" percentages) are applied to the determined fair value of the mortgage pipeline. Changes to the fair value of interest rate lock commitments are recognized based on interest rate changes, changes in the probability that the commitment will be exercised, and the passage of time. The fair value of the forward sales contracts to investors considers the market price movement of the same type of security between the trade date and the balance sheet date. These instruments are classified as Level 2 within the valuation hierarchy.

In November 2009, Synovus sold certain Visa Class B shares to another Visa USA member financial institution. The sales price was based on the Visa stock conversion ratio in effect at the time for conversion of Visa Class B shares to Visa Class A unrestricted shares at a future date. In conjunction with the sale, Synovus entered into a derivative contract with the purchaser (the Visa derivative), which provides for settlements between the parties based upon a change in the ratio for conversion of Visa Class B shares to Visa Class A shares. The fair value of the Visa derivative is determined based on management's estimate of the timing and amount of the Covered Litigation settlement and the resulting payments due to the counterparty under the terms of the contract. Since this estimation process requires application of judgment in developing significant unobservable inputs used to determine the fair value of the Visa derivative, this derivative has been classified as Level 3 within the valuation hierarchy. See "Part II - Item 8. Financial Statements and Supplementary Data - Note 17 - Visa Shares and Related Agreements" of this Report for additional discussion on the Visa derivative and related litigation.

^{(1 )} Based on an analysis of the nature and risks of these investments, Synovus has determined that presenting these investments as a single asset class is appropriate.

^{(2 )} Mortgage derivatives consist of customer interest rate lock commitments that relate to the potential origination of mortgage loans, which would be classified as held for sale and forward loan sales commitments with third-party investors.

Fair Value Option

The following table summarizes the difference between the fair value and the unpaid principal balance of mortgage loans held for sale measured at fair value and the changes in fair value of these loans. Mortgage loans held for sale are initially measured at fair value with subsequent changes in fair value recognized in earnings. Changes in fair value were recorded as a component of mortgage banking income in the consolidated statements of income. An immaterial portion of these changes in fair value was attributable to changes in instrument-specific credit risk.

As noted above, Synovus uses significant unobservable inputs (Level 3) in determining the fair value of assets and liabilities classified as Level 3 in the fair value hierarchy. The table below includes a roll-forward of the amounts on the consolidated balance sheet for the year ended December 31, 2015 and 2014 (including the change in fair value), for financial instruments of a material nature that are classified by Synovus within Level 3 of the fair value hierarchy and are measured at fair value on a recurring basis. Transfers between fair value levels are recognized at the end of the reporting period in which the associated changes in inputs occur. During 2015 and 2014, Synovus did not have any transfers between levels in the fair value hierarchy.

Assets Measured at Fair Value on a Non-recurring Basis

Certain assets are recorded at fair value on a non-recurring basis. These non-recurring fair value adjustments typically are a result of the application of lower of cost or fair value accounting or a write-down occurring during the period. For example, if the fair value of an asset in these categories falls below its cost basis, it is considered to be at fair value at the end of the period of the adjustment. The following table presents assets measured at fair value on a non-recurring basis as of the dates indicated for which there was a fair value adjustment during the period.

* Impaired loans that are collateral-dependent.

Collateral-dependent impaired loans are evaluated for impairment in accordance with the provisions of ASC 310-10-35 using the fair value of the collateral less costs to sell. For loans measured using the estimated fair value of collateral securing these loans less costs to sell, fair value is generally determined based upon appraisals performed by a certified or licensed appraiser using inputs such as absorption rates, capitalization rates, and market comparables, adjusted for estimated selling costs. Management also considers other factors or recent developments, such as changes in absorption rates or market conditions from the time of valuation, and anticipated sales values considering management's plans for disposition, which could result in adjustments to the collateral value estimates indicated in the appraisals. Estimated costs to sell are based on actual amounts for similar assets. These measurements are classified as Level 3 within the valuation hierarchy. Collateral-dependent impaired loans are reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly based on the same factors identified above.

Loans are transferred to other loans held for sale at fair value when Synovus makes the determination to sell specifically identified loans. The fair value of the loans is primarily determined by analyzing the underlying collateral of the loan and the anticipated market prices of similar assets less estimated costs to sell, as well as consideration of the market for loan sales versus the sale of collateral. At the time of transfer, if the estimated fair value is less than the carrying amount, the difference is recorded as a charge-off against the allowance for loan losses. Decreases in the fair value subsequent to the transfer, as well as gains/losses realized from the sale of these assets, are recorded as losses on other loans held for sale, net, as a component of non-interest expense on the consolidated statements of income.

ORE consists of properties obtained through a foreclosure proceeding or through an in-substance foreclosure in satisfaction of loans. The fair value of ORE is determined on the basis of current appraisals, comparable sales, and other estimates of fair value obtained principally from independent sources, adjusted for estimated selling costs. At foreclosure, ORE is recorded at the lower of cost or fair value less the estimated cost to sell, which establishes a new cost basis. Subsequent to foreclosure, ORE is evaluated quarterly and reported at fair value less estimated costs to sell, not to exceed the new cost basis, determined on the basis of current appraisals, comparable sales, and other estimates of fair value obtained principally from independent sources, adjusted for estimated selling costs. In the determination of fair value subsequent to foreclosure, management also considers other factors or recent developments, such as changes in absorption rates or market conditions from the time of valuation, and anticipated sales values considering management’s plans for disposition, which could result in an adjustment to lower the fair value estimates indicated in the appraisals. Internally adjusted valuations are considered Level 3 measurements as management uses assumptions that may not be observable in the market.

131

Other assets held for sale consist of certain premises and equipment held for sale, including those related to the efficiency initiatives discussed in "Note 3 - Restructuring Charges" of this Report. These assets are classified as held for sale and recorded at the lower of their amortized cost or fair value, less costs to sell, consistent with ASC 360-10, Impairment and Disposal of Long-Lived Assets. The fair value of these assets is determined primarily on the basis of appraisals or BOV, as circumstances warrant, adjusted for estimated selling costs. Both techniques engage licensed or certified professionals that use inputs such as absorption rates, capitalization rates, and market comparables; these valuations are considered Level 3 measurements since assumptions or inputs may not be observable in the market.

Quantitative Information about Level 3 Fair Value Measurements

The tables below provide an overview of the valuation techniques and significant unobservable inputs used in those techniques to measure financial instruments that are classified within Level 3 of the valuation hierarchy. The range of sensitivities that management utilized in its fair value calculations is deemed acceptable in the industry with respect to the identified financial instruments. The tables below present both the total balance as of the dates indicated for assets measured at fair value on a recurring basis and the assets measured at fair value on a non-recurring basis for which there was a fair value adjustment during the period.

Sensitivity Analysis of Level 3 Unobservable Inputs Measured on a Recurring Basis

Included in the fair value estimates of financial instruments carried at fair value on the consolidated balance sheet are those estimated in full or in part using valuation techniques based on assumptions that are not supported by observable market prices, rates, or other inputs. Unobservable inputs are assessed carefully, considering the current economic environment and market conditions. However, by their very nature, unobservable inputs imply a degree of uncertainty in their determination, because they are supported by little, if any, market activity for the related asset or liability.

134

Investment Securities Available for Sale

The significant unobservable inputs used in the fair value measurement of the corporate obligations in Level 3 assets are the credit spread embedded in the discount rate and the discount for lack of liquidity. Generally, a change in one or more assumptions, and the degree or sensitivity of the change used, can have a significant impact on fair value. With regard to the trust preferred securities in Level 3 assets, raising the credit spread, and raising the discount for lack of liquidity assumptions will result in a lower fair value measurement.

Private Equity Investments

In the absence of quoted market prices, inherent lack of liquidity, and the long-term nature of private equity investments, significant judgment is required to value these investments. The significant unobservable inputs used in the fair value measurement of private equity investments include current operations, financial condition and cash flows, comparables and private sales, when available, and recently executed financing transactions related to investee companies. Significant increases or decreases in any of these inputs in isolation would result in a significantly lower or higher fair value measurement.

Visa Derivative Liability

The fair value of the Visa derivative is determined based on management's estimate of the timing and amount of the Covered Litigation settlement and the resulting payments due to the counterparty under the terms of the contract. Significant changes in any of these inputs could result in a significantly higher (lower) valuation of the Visa derivative liability. Also, additional funding into the escrow generally results in a proportional increase in our derivative liability.

Fair Value of Financial Instruments

The following table presents the carrying and fair values of financial instruments at December 31, 2015 and 2014. The fair values represent management’s best estimates based on a range of methodologies and assumptions. For financial instruments that are not recorded at fair value on the balance sheet, such as loans, interest bearing deposits (including brokered deposits), and long-term debt, the fair value amounts should not be taken as an estimate of the amount that would be realized if all such financial instruments were to be settled immediately.

Cash and cash equivalents, interest bearing funds with the Federal Reserve Bank, interest earning deposits with banks, and federal funds sold and securities purchased under resale agreements are repriced on a short-term basis; as such, the carrying value closely approximates fair value. Since these amounts generally relate to highly liquid assets, these are considered a Level 1 measurement.

Loans, net of deferred fees and costs, are recorded at the amount of funds advanced, less charge-offs, and an estimation of credit risk represented by the allowance for loan losses. The fair value estimates for disclosure purposes differentiate loans based on their financial characteristics, such as product classification, loan category, pricing features, and remaining maturity. The fair value of loans is estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type, such as commercial, mortgage, home equity, credit card, and other retail loans. Commercial loans are further segmented into certain collateral code groupings. The fair value of the loan portfolio is calculated, in accordance with ASC 825-10, by discounting contractual cash flows using estimated market discount rates, which reflect the credit and interest rate risk inherent in the loan. This method of estimating fair value does not incorporate the exit-price concept of fair value prescribed by ASC 820-10 and generally produces a higher value than the exit price approach. For loans measured using the estimated fair value of collateral less costs to sell, fair value is generally estimated using appraisals of the collateral. Collateral values are monitored and additional write-downs are recognized if it is determined that the estimated collateral values have declined further. Estimated costs to sell are based on current disposal costs for similar assets. Carrying value is considered to reflect fair value for these loans. Loans are considered a Level 3 fair value measurement.

The fair value of deposits with no stated maturity, such as non-interest bearing demand accounts, interest bearing demand deposits, money market accounts, and savings accounts, is estimated to be equal to the amount payable on demand as of that respective date. The fair value of time deposits is based on the discounted value of contractual cash flows. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities. The value of long-term relationships with depositors is not taken into account in estimating fair values. Synovus has developed long-term relationships with its customers through its deposit base and, in the opinion of management, these customer relationships add significant value to Synovus. Synovus has determined that the appropriate classification for deposits is Level 2 due to the ability to reasonably measure all inputs to valuation based on observable market variables. Short-term and long-term debt is also considered a Level 2 valuation, as management relies on market prices for bonds or debt that is similar, but not necessarily identical, to the debt being valued. Short-term debt that matures within ten days is assumed to be at fair value, and is considered a Level 1 measurement. The fair value of other short-term and long-term debt with fixed interest rates is calculated by discounting contractual cash flows using market discount rates for bonds or debt that is similar but not identical.

Note 15 - Derivative Instruments

As part of its overall interest rate risk management activities, Synovus utilizes derivative instruments to manage its exposure to various types of interest rate risk. These derivative instruments generally consist of interest rate swaps, interest rate lock commitments made to prospective mortgage loan customers, and commitments to sell fixed-rate mortgage loans. Interest rate lock commitments represent derivative instruments since it is intended that such loans will be sold.

Synovus may also utilize interest rate swaps to manage interest rate risks primarily arising from its core banking activities. These interest rate swap transactions generally involve the exchange of fixed and floating interest rate payment obligations without the exchange of underlying principal amounts. Swaps may be designated as either cash flow hedges or fair value hedges, as discussed below. As of December 31, 2015 and 2014, Synovus had no outstanding interest rate swap contracts utilized to manage interest rate risk.

Synovus is party to master netting arrangements with its dealer counterparties; however, Synovus does not offset assets and liabilities under these arrangements for financial statement presentation purposes.

Counterparty Credit Risk and Collateral

Entering into derivative contracts potentially exposes Synovus to the risk of counterparties’ failure to fulfill their legal obligations, including, but not limited to, potential amounts due or payable under each derivative contract. Notional principal amounts are often used to express the volume of these transactions, but the amounts potentially subject to credit risk are much smaller. Synovus assesses the credit risk of its dealer counterparties by regularly monitoring publicly available credit rating information, evaluating other market indicators, and periodic detailed financial reviews. Dealer collateral requirements are determined via risk-based policies and procedures and in accordance with existing agreements. Synovus seeks to minimize dealer credit risk by dealing with highly rated counterparties and by obtaining collateral for exposures above certain predetermined limits. Management closely monitors credit conditions within the customer swap portfolio, which management deems to be of higher risk than dealer counterparties. Collateral is secured at origination and credit related fair value adjustments are recorded against the asset value of the derivative as deemed necessary based upon an analysis, which includes consideration of the current asset value of the swap, customer credit rating, collateral value, and customer standing with regards to its swap contractual obligations

137

and other related matters. Such asset values fluctuate based upon changes in interest rates regardless of changes in notional amounts and changes in customer specific risk.

Cash Flow Hedges

Synovus designates hedges of floating rate loans as cash flow hedges. These swaps hedge against the variability of cash flows from specified pools of floating rate prime based loans. Synovus calculates effectiveness of the hedging relationship quarterly using regression analysis. The effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transactions affect earnings. Ineffectiveness from cash flow hedges is recognized in the consolidated statements of income as a component of other non-interest income. As of December 31, 2015, there were no cash flow hedges outstanding, and therefore, no cumulative ineffectiveness.

Synovus expects to reclassify from accumulated other comprehensive income (loss) $196 thousand to loss on early extinguishment of debt and $271 thousand to interest expense during the next twelve months as amortization of deferred losses is recorded.

Synovus did not terminate any cash flow hedges during 2015 or 2014. The remaining unamortized deferred loss balance of all previously terminated cash flow hedges at December 31, 2015 and 2014 was $(597) thousand and $(1.1) million, respectively.

Fair Value Hedges

Synovus designates hedges of fixed rate liabilities as fair value hedges. These swaps hedge against the change in fair value of various fixed rate liabilities due to changes in the benchmark interest rate, LIBOR. Synovus calculates effectiveness of the fair value hedges quarterly using regression analysis. Ineffectiveness from fair value hedges is recognized in the consolidated statements of income as a component of other non-interest income. As of December 31, 2015, there were no fair value hedges outstanding, and therefore, no cumulative ineffectiveness.

Synovus did not terminate any fair value hedges during 2015 or 2014. The remaining unamortized deferred gain balance on all previously terminated fair value hedges at December 31, 2015 and 2014 was $4.0 million and $7.6 million, respectively. Synovus expects to reclassify from hedge-related basis adjustment, a component of long-term debt, $1.8 million of the deferred gain balance on previously terminated fair value hedges as a reduction to interest expense during the next twelve months as amortization of deferred gains is recorded. Additionally, Synovus will record $1.3 million of the deferred gain balance to loss on early extinguishment of debt during the first quarter of 2016.

Customer Related Derivative Positions

Synovus enters into interest rate swap agreements to facilitate the risk management strategies of a small number of commercial banking customers. Synovus mitigates this risk by entering into equal and offsetting interest rate swap agreements with highly rated counterparties. The interest rate swap agreements are free-standing derivatives and are recorded at fair value on Synovus' consolidated balance sheet. Fair value changes are recorded in non-interest income in Synovus' consolidated statements of income. As of December 31, 2015, the notional amount of customer related interest rate derivative financial instruments, including both the customer position and the offsetting position, was $1.28 billion, an increase of $184.8 million compared to December 31, 2014.

Visa Derivative

In conjunction with the sale of Class B shares of common stock issued by Visa to Synovus as a Visa USA member, Synovus entered into a derivative contract with the purchaser, which provides for settlements between the parties based upon a change in the ratio for conversion of Visa Class B shares to Visa Class A shares. The conversion ratio changes when Visa deposits funds to a litigation escrow established by Visa to pay settlements for certain litigation, for which Visa is indemnified by Visa USA members. The litigation escrow is funded by proceeds from Visa’s conversion of Class B shares. The fair value of the derivative contract was $1.4 million at December 31, 2015 and 2014. The fair value of the derivative contract is determined based on management's estimate of the timing and amount of the Covered Litigation settlement, and the resulting payments due to the counterpary under the terms of the contract. See "Part II - Item 8. Financial Statements and Supplementary Data - Note 17 - Visa Shares and Related Agreements" of this Report for further information.

Mortgage Derivatives

Synovus originates first lien residential mortgage loans for sale into the secondary market. Mortgage loans are sold by Synovus for conversion to securities and the servicing of these loans is generally sold to a third-party servicing aggregator, or Synovus sells the mortgage loans as whole loans to investors either individually or in bulk on a servicing released basis.

Synovus enters interest rate lock commitments for residential mortgage loans which commits it to lend funds to a potential borrower at a specific interest rate and within a specified period of time. Interest rate lock commitments that relate to the origination

138

of mortgage loans that, if originated, will be held for sale, are considered derivative financial instruments under applicable accounting guidance. Outstanding interest rate lock commitments expose Synovus to the risk that the price of the mortgage loans underlying the commitments may decline due to increases in mortgage interest rates from inception of the rate lock to the funding of the loan.

At December 31, 2015 and 2014, Synovus had commitments to fund at a locked interest rate, primarily fixed-rate mortgage loans to customers in the amount of $88.8 million and $73.4 million, respectively. The fair value of these commitments resulted in a gain of $175 thousand and $606 thousand for the year ended December 31, 2015 and 2014, respectively, which was recorded as a component of mortgage banking income in the consolidated statements of income.

At December 31, 2015 and 2014, outstanding commitments to sell primarily fixed-rate mortgage loans amounted to $95.0 million and $113.0 million, respectively. Such commitments are entered into to reduce the exposure to market risk arising from potential changes in interest rates, which could affect the fair value of mortgage loans held for sale and outstanding rate lock commitments, which guarantee a certain interest rate if the loan is ultimately funded or granted by Synovus as a mortgage loan held for sale. The commitments to sell mortgage loans are at fixed prices and are scheduled to settle at specified dates that generally do not exceed 90 days. The fair value of outstanding commitments to sell mortgage loans resulted in a gain of $924 thousand and a loss of $(1.7) million for the years ended December 31, 2015 and 2014, respectively, which was recorded as a component of mortgage banking income in the consolidated statements of income.

Collateral Contingencies

Certain derivative instruments contain provisions that require Synovus to maintain an investment grade credit rating from each of the major credit rating agencies. If Synovus’ credit rating falls below investment grade, these provisions allow the counterparties of the derivative instrument to demand immediate and ongoing full collateralization on derivative instruments in net liability positions and, for certain counterparties, request immediate termination. Additionally, certain counterparties require full collateralization on derivative instruments in a net liability position. Also, as of June 10, 2013, the CCC became mandatory for certain trades as required under the Dodd-Frank Act. These derivative transactions also carry collateral requirements, both at the inception of the trade, and as the value of each derivative position changes. As trades are migrated to the CCC, dealer counterparty exposure will be reduced, and higher notional amounts of Synovus' derivative instruments will be housed at the CCC, a highly regulated and well-capitalized entity. As of December 31, 2015, collateral totaling $65.9 million of Federal funds sold was pledged to the derivative counterparties, including $13.7 million with the CCC, to comply with collateral requirements.

⁽¹⁾ Gain (loss) represents net fair value adjustments (including credit related adjustments) for customer swaps and offsetting positions.

⁽²⁾ Gain (loss) represents net fair value adjustments recorded for interest rate lock commitments and commitments to sell mortgage loans to third-party investors.

During the years ended December 31, 2015, 2014, and 2013, Synovus reclassified $3.1 million, $3.1 million, and $3.2 million, respectively, from hedge-related basis adjustment, a component of long-term debt, as a reduction to interest expense. Additionally, during 2015, Synovus reclassified $495 thousand from hedge-related basis adjustment, as a reduction to loss on early extinguishment of debt. These deferred gains relate to hedging relationships that have been previously terminated and are reclassified into earnings over the remaining life of the hedged items.

Note 16 - Variable Interest Entities

Synovus has a contractual ownership or other interests in certain VIEs for which the fair value of the VIE's net assets may change exclusive of the variable interests. Under ASC 810, Consolidation, Synovus is deemed to be the primary beneficiary and required to consolidate a VIE if it has a variable interest in the VIE that provides it with a controlling financial interest. For such purposes, the determination of whether a controlling financial interest exists is based on whether a single party has both the power to direct the activities of the VIE that most significantly impact the VIE's economic performance and the obligation to absorb the losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. ASC 810-10-65, as amended, requires continual reconsideration of conclusions reached regarding which interest holder is a VIE's primary beneficiary.

Synovus’ involvement with VIEs is discussed below. Synovus consolidates VIEs for which it is deemed the primary beneficiary.

Consolidated Variable Interest Entities

Rabbi Trusts – Synovus has established certain rabbi trusts related to deferred compensation plans offered to its employees. Synovus contributes employee cash compensation deferrals to the trusts and directs the underlying investments made by the trusts. The assets of these trusts are available to Synovus creditors only in the event that Synovus becomes insolvent. These trusts are considered VIEs because either there is no equity at risk in the trusts or because Synovus provided the equity interest to its employees in exchange for services rendered. While the employees have the ability to direct their funds within the trusts, Synovus is considered the primary beneficiary of the rabbi trusts as it has the ability to direct the underlying investments made by the trusts as well as make funding decisions related to the trusts, the activities that most significantly impact the economic performance of the rabbi trusts. Synovus includes the assets of the rabbi trusts as a component of other assets and a corresponding liability for the associated benefit obligation in other liabilities in its consolidated balance sheets. At December 31, 2015 and 2014, the aggregate amount of rabbi trust assets and benefit obligation was $10.7 million and $11.3 million, respectively.

Non-consolidated Variable Interest Entities

Low Income Housing Tax Credit Partnerships – Synovus and its subsidiary bank, Synovus Bank, make equity investments as a limited partner in various partnerships which are engaged in the development and operation of affordable multi-family housing utilizing the LIHTC pursuant to Section 42 of the Internal Revenue Code. The purpose of these investments is to earn a return on the investment and to support community reinvestment initiatives of Synovus’ subsidiary bank. The activities of these LIHTC

140

partnerships are limited to development and operation of multi-family housing that is leased to qualifying residential tenants. These partnerships are generally located in southeastern communities where Synovus has a banking presence and are considered VIEs because Synovus, as the holder of an equity investment at risk, does not have voting or similar rights and does not participate in the management or direct the operations of the partnerships (activities which affect the success of the partnerships). Synovus provides construction lending for certain of the LIHTC partnerships in which it also has an equity investment. Synovus is at risk for the amount of its equity investment plus the outstanding amount of any construction loans in excess of the fair value of the collateral for the loan but has no obligation to fund the operations or working capital of the partnerships. The general partners of these partnerships are considered the primary beneficiaries because they are charged with management responsibility which give them the power to direct the activities that most significantly impact the financial performance of the partnerships, and they are exposed to losses beyond Synovus’ equity investment. At December 31, 2015 and 2014, the aggregate carrying value of Synovus’ investments in LIHTC partnerships was $18.9 million and $10.9 million, respectively, and the cumulative amount of equity investments was $29.3 million in 2015 and $29.1 million in 2014. Synovus uses the equity method of accounting for these investments which are included as a component of other assets on Synovus’ consolidated balance sheet. At December 31, 2015 and 2014, Synovus had $12.2 million and $3.6 million, respectively, commitments to fund equity investments in LIHTC partnerships.

Certain Commercial Loans – For certain troubled commercial loans, Synovus restructures the terms of the borrower’s debt in an effort to increase the probability of receipt of amounts contractually due. A troubled debt restructuring generally requires consideration of whether the borrowing entity is a VIE as economic events may have proven that the entity’s equity is not sufficient to permit it to finance its activities without additional subordinated financial support or a restructuring of the terms of its financing. As Synovus does not have the power to direct the activities that most significantly impact such troubled commercial borrowers’ operations, it is not considered the primary beneficiary, even in situations where, based on the size of the financing provided, Synovus is exposed to potentially significant benefits and losses of the borrowing entity. Synovus has no contractual requirements to provide financial support to the borrowing entities beyond certain funding commitments established upon restructuring of the terms of the debt that allow for preparation of the underlying collateral for sale.

Note 17 - Visa Shares and Related Agreements

Synovus is a member of the Visa USA network and received shares of Visa Class B common stock in exchange for its membership interest in Visa USA in conjunction with the Visa IPO in 2008. Visa members have indemnification obligations with respect to the Covered Litigation. Visa Class B shares are subject to certain restrictions until settlement of the Covered Litigation. As of December 31, 2015, all of the Covered Litigation had not been settled. Visa has established a litigation escrow to fund settlement of the Covered Litigation. The litigation escrow is funded by proceeds from Visa's conversion of Class B shares to Class A shares.

In November 2009, Synovus sold its remaining Visa Class B shares to another Visa USA member financial institution. In conjunction with the sale, Synovus entered into a derivative contract with the purchaser which provides for settlements between the parties based upon a change in the ratio for conversion of Visa Class B shares to Visa Class A shares. As of December 31, 2015 and 2014, the fair value of the derivative contract was $1.4 million. The fair value of the derivative contract is determined based on management's estimate of the timing and amount of the Covered Litigation settlement, and the resulting payments due to the counterparty under the terms of the contract. For the years ended December 31, 2015, 2014 and 2013, Synovus recognized indemnification charges of $1.5 million, $3.0 million and $1.6 million, respectively.

Management believes that the estimate of Synovus' exposure to the Visa indemnification and fees associated with the Visa derivative is adequate based on current information, including Visa's recent announcements and disclosures. However, future developments in the litigation could require potentially significant changes to Synovus' estimate.

Note 18 - Commitments and Contingencies

In the normal course of business, Synovus enters into commitments to extend credit such as loan commitments and letters of credit to meet the financing needs of its customers. Synovus uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee.

The contractual amount of these financial instruments represents Synovus' maximum credit risk should the counterparty draw upon the commitment, and should the counterparty subsequently fail to perform according to the terms of the contract. Since many of the commitments are expected to expire without being drawn upon, total commitment amounts do not necessarily represent future cash requirements.

141

The carrying amount of loan commitments and letters of credit closely approximates the fair value of such financial instruments. Carrying amounts include unamortized fee income and, in some instances, allowances for any estimated credit losses from these financial instruments. These amounts are not material to Synovus' consolidated balance sheets.

Unfunded lending commitments and letters of credit at December 31, 2015 are presented below.

(in thousands)
Letters of credit*	$	166,936
Commitments to fund commercial real estate, construction, and land development loans	1,882,130

Commitments to fund commercial and industrial loans	4,094,809
Other loan commitments	272,630
Total unfunded lending commitments and letters of credit	$	8,523,072

* Represents the contractual amount net of risk participations of $66 million.

Lease Commitments

Synovus and its subsidiaries have entered into long-term operating leases for various facilities and equipment. Management expects that as these leases expire they will be renewed or replaced by similar leases based on need.

At December 31, 2015, minimum rental commitments under all such non-cancelable leases for the next five years and thereafter are presented below.

Total	$	292,617

Rental expense on facilities was $26.6 million, $25.9 million, and $25.6 million for the years ended December 31, 2015, 2014, and 2013, respectively.

Repurchase Obligations for Mortgage Loans Originated for Sale

The majority of mortgage loans originated by Synovus are sold to third-party purchasers on a servicing released basis, without recourse, or continuing involvement (Synovus does not retain the servicing rights). These loans are originated and underwritten internally by Synovus personnel and are primarily to borrowers in Synovus’ geographic market footprint. These sales are typically effected as non-recourse loan sales to GSEs and non-GSE purchasers.

Each GSE and non-GSE purchaser has specific guidelines and criteria for sellers of loans, and the risk of credit loss with regard to the principal amount of the loans sold is generally transferred to the purchasers upon sale. The purchase agreements require Synovus to make certain representations and warranties regarding the existence and sufficiency of file documentation and the absence of fraud by borrowers or other third parties such as appraisers in connection with obtaining the loan. If it is determined that loans sold were in breach of these representations or warranties, Synovus has obligations to either repurchase the loan at the unpaid principal balance and related investor fees or make the purchaser whole for the economic benefits of the loan.

To date, repurchase activity pursuant to the terms of these representations and warranties has been minimal and has primarily been associated with loans originated from 2005 through 2008. From January 1, 2005 through December 31, 2015, Synovus Mortgage originated and sold approximately $8.9 billion of first lien GSE eligible mortgage loans and approximately $3.9 billion of first and second lien non-GSE eligible mortgage loans. The total expense pertaining to losses from repurchases of mortgage loans previously sold, including amounts accrued in accordance with ASC 450, was $920 thousand, $2.0 million, and $1.7 million for the years ended December 31, 2015, 2014, and 2013, respectively. The total accrued liability related to mortgage repurchase claims was $3.2 million at both December 31, 2015 and December 31, 2014.

Note 19 - Legal Proceedings

Synovus and its subsidiaries are subject to various legal proceedings and claims that arise in the ordinary course of its business. Additionally, in the ordinary course of business, Synovus and its subsidiaries are subject to regulatory examinations, information gathering requests, inquiries and investigations. Synovus, like many other financial institutions, has been the target of numerous legal actions and other proceedings asserting claims for damages and related relief for losses. These actions include claims and counterclaims asserted by individual borrowers related to their loans and allegations of violations of state and federal laws and regulations relating to banking practices, including putative class action matters. In addition to actual damages if Synovus does not prevail in any asserted legal action, credit-related litigation could result in additional write-downs or charge-offs of assets, which could adversely affect Synovus' results of operations during the period in which the write-down or charge-off were to occur.

Synovus carefully examines and considers each legal matter, and, in those situations where Synovus determines that a particular legal matter presents loss contingencies that are both probable and reasonably estimable, Synovus establishes an appropriate accrual. An event is considered to be probable if the future event is likely to occur. While the final outcome of any legal proceeding is inherently uncertain, based on the information currently available, advice of counsel and available insurance coverage, management believes that the amounts accrued with respect to legal matters as of December 31, 2015 are adequate. The actual costs of resolving legal claims may be higher or lower than the amounts accrued.

In addition, where Synovus determines that there is a reasonable possibility of a loss in respect of legal matters, including those legal matters described below, Synovus considers whether it is able to estimate the total reasonably possible loss or range of loss. An event is “reasonably possible” if “the chance of the future event or events occurring is more than remote but less than likely.” An event is “remote” if “the chance of the event or future event occurring is more than slight but less than reasonably possible." In many situations, Synovus may be unable to estimate reasonably possible losses due to the preliminary nature of the legal matters, as well as a variety of other factors and uncertainties. For those legal matters where Synovus is able to estimate a range of reasonably possible losses, management currently estimates the aggregate range from our outstanding litigation, including, without limitation, the matters described below, is from zero to $15 million in excess of the amounts accrued, if any, related to those matters. This estimated aggregate range is based upon information currently available to Synovus, and the actual losses could prove to be higher. As there are further developments in these legal matters, Synovus will reassess these matters, and the estimated range of reasonably possible losses may change as a result of this assessment. Based on Synovus' current knowledge and advice of counsel, management presently does not believe that the liabilities arising from these legal matters will have a material adverse effect on Synovus' consolidated financial condition, results of operations or cash flows. However, it is possible that the ultimate resolution of these legal matters could have a material adverse effect on Synovus' results of operations for any particular period.

Synovus intends to vigorously pursue all available defenses to these legal matters, but will also consider other alternatives, including settlement, in situations where there is an opportunity to resolve such legal matters on terms that Synovus considers to be favorable, including in light of the continued expense and distraction of defending such legal matters. Synovus also maintains insurance coverage, which may (or may not) be available to cover legal fees, or potential losses that might be incurred in connection with the legal matters described below. The above-noted estimated range of reasonably possible losses does not take into consideration insurance coverage which may or may not be available for the respective legal matters.

Posting Order Litigation

On September 21, 2010, Synovus, Synovus Bank and CB&T were named as defendants in a putative multi-state class action relating to the manner in which Synovus Bank charges overdraft fees to customers. The case, Childs et al. v. Columbus Bank and Trust et al., was filed in the Northern District of Georgia, Atlanta Division, and asserted claims for breach of contract and breach of the covenant of good faith and fair dealing, unconscionability, conversion and unjust enrichment for alleged injuries suffered by plaintiffs as a result of Synovus Bank's assessment of overdraft charges in connection with its POS/debit and automated-teller machine cards transactions allegedly resulting from the sequence used to post payments to the plaintiffs' accounts. On October 25, 2010, the Childs case was transferred to a multi-district proceeding in the Southern District of Florida. On August 23, 2014, Synovus reached a settlement in principle with plaintiffs' counsel to settle the Posting Order Litigation. Under the settlement in principle, Synovus agreed to pay $3.75 million plus payment of $150,000 in settlement expenses (the "Posting Order Settlement Payment") in exchange for broad releases, dismissal with prejudice of the Posting Order Litigation and other material and customary terms and conditions. The District Court granted final approval of the Posting Order Settlement Payment on April 2, 2015.

TelexFree Litigation

On October 22, 2014, several pending lawsuits were consolidated into a multi-district putative class action case captioned In re: TelexFree Securities Litigation, MDL Number 4:14-md2566-TSH, United States District Court District of Massachusetts. Synovus and Synovus Bank were named as defendants with numerous other defendants in the purported class action lawsuit.  An Amended Complaint was filed on March 31, 2015 which consolidated and amended the claims previously asserted. The claims against Synovus were dismissed by Plaintiffs on April 10, 2015 so now, as to Synovus-related entities, only claims against Synovus Bank remain pending.  TelexFree was a merchant customer of Base Commerce, LLC, an independent sales organization/member

143

service provider sponsored by Synovus Bank. The purported class action lawsuit generally alleges that TelexFree engaged in an improper multi-tier marketing scheme involving voice-over Internet protocol telephone services and that the various defendants, including Synovus Bank, provided financial services to TelexFree that allowed TelexFree to conduct its business operations. Synovus Bank filed a motion to dismiss the lawsuit on June 1, 2015, which remains pending before the Court.

Synovus Bank believes it has substantial defenses related to these purported claims and intends to vigorously defend the claims asserted. Synovus currently cannot reasonably estimate losses attributable to this matter.

Note 20 - Employment Expenses and Benefit Plans

For the years ended December 31, 2015, 2014, and 2013, Synovus provided a 100% matching contribution on the first 4% of eligible employee 401(k) contributions for a total annual contribution of $9.9 million, $9.4 million, and $9.1 million, respectively.

For the years ended December 31, 2015, 2014, and 2013, Synovus had a stock purchase plan for directors and employees whereby Synovus made contributions equal to 15% of every $1 of employee and director voluntary contributions according to the years of service schedule, subject to certain maximum contribution limitations. The funds are used to purchase outstanding shares of Synovus common stock. Synovus recorded as expense $835 thousand, $880 thousand, and $955 thousand for contributions to these plans in 2015, 2014, and 2013, respectively.

Synovus also has a non-contributory profit sharing plan that covers all eligible employees. The company may contribute a discretionary contribution to this plan on an annual basis. For the years ended December 31, 2015, 2014, and 2013, Synovus did not make contributions to the profit sharing plan.

Note 21 - Share-based Compensation

General Description of Share-based Plans

Synovus has a long-term incentive plan under which the Compensation Committee of the Board of Directors has the authority to grant share-based awards to Synovus employees. The 2013 Omnibus Plan authorizes 8,571,429 common share equivalents available for grant, where grants of options count as one share equivalent and grants of full value awards (e.g., restricted share units, market restricted share units, and performance share units) count as two share equivalents. Any restricted share units that are forfeited and options that expire unexercised will again become available for issuance under the Plan. At December 31, 2015, Synovus had a total of 7,050,823 shares of its authorized but unissued common stock reserved for future grants under the 2013 Omnibus Plan. The Plan permits grants of share-based compensation including stock options, restricted share units, market restricted share units, and performance share units. The grants generally include vesting periods ranging from three to five years and contractual terms of ten years. Stock options are granted at exercise prices which equal the fair market value of a share of common stock on the grant date. As further discussed below, market restricted share units and performance share units are granted at target and are compared annually to required market and performance metrics. Synovus has historically issued new shares to satisfy share option exercises and share unit conversions. Dividend equivalents are paid on outstanding restricted share units, market restricted share units, and performance share units in the form of additional restricted share units that vest over the same vesting period or the vesting period left on the original restricted share unit grant.

During 2015, Synovus awarded 321,874 restricted share units to employees and non-employee directors that contained a service-based vesting period of three years. During 2015, Synovus also granted 82,152 market restricted share units and 82,152 performance share units to senior management. The weighted average grant-date fair value of the awarded restricted share units, market restricted share units, and performance share units was $28.09, $29.39, and $28.06 per share, respectively. During 2014, Synovus awarded 407,374 restricted share units to employees and non-employee directors that contained a service-based vesting period of three years. During 2014, Synovus also granted 90,117 market restricted share units and 67,157 performance share units to senior management. The weighted average grant-date fair value of the awarded restricted share units, market restricted share units, and performance share units was $23.69, $24.30, and $23.47 per share, respectively. During 2013, Synovus granted 212,660 restricted share units and 40,512 market restricted share units with a weighted average grant-date fair value of $19.60 and $24.43, respectively. The restricted share units and the market restricted share units granted during 2015, 2014, and 2013 contain a service-based vesting period of three years with most awards vesting pro-rata over three years. During 2013, Synovus also granted 857,607 stock options with a weighted average exercise price of $17.64 and service-based vesting pro-rata over three years.

Share-based Compensation Expense

Total share-based compensation expense was $12.6 million, $10.2 million, and $7.5 million for 2015, 2014, and 2013, respectively. The total income tax benefit recognized in the consolidated statements of income for share-based compensation arrangements was approximately $4.6 million, $3.9 million, and $2.9 million for 2015, 2014, and 2013, respectively. No share-based compensation costs have been capitalized for the years ended December 31, 2015, 2014, and 2013.

144

As of December 31, 2015, unrecognized compensation cost related to the unvested portion of share-based compensation arrangements involving shares of Synovus stock was approximately $15.2 million.

Stock Options

The fair value of stock option grants used in measuring compensation expense was determined using the Black-Scholes option pricing model with the following weighted-average assumptions for grants made in 2013. There were no stock option grants in 2015 or 2014.

	2013
Risk-free interest rate	1.11	%
Expected stock price volatility	50.0
Dividend yield	1.6
Expected life of options	6.0 years

The stock price expected volatility for awards granted in 2013 was based on Synovus' historical and implied volatility. The expected life for stock options granted during 2013 was calculated using the “simplified” method as prescribed by SAB No. 110. The weighted average grant-date fair value of stock options granted in 2013 was $7.21.

A summary of stock option activity and changes during the years ended December 31, 2015, 2014, and 2013 is presented below.

Options exercisable at end of year	1,504,783		$	41.08	1,870,516		$	55.40	1,999,195		$	68.74

The aggregate intrinsic value for outstanding stock options at December 31, 2015 was $19.3 million and the aggregate intrinsic value for options exercisable at December 31, 2015 was $15.8 million. As of December 31, 2015, the weighted average remaining contractual life was 4.90 years for options outstanding and 4.54 years for options exercisable.

The intrinsic value of stock options exercised during the years ended December 31, 2015, 2014, and 2013 was $4.4 million, $1.3 million, and $367 thousand, respectively. Cash received from option exercises of common stock for the years ended December 31, 2015, 2014, and 2013 was $5.6 million, $3.0 million, and $1.0 million, respectively. The total grant date fair value of stock options vested during 2015, 2014, and 2013 was $6.5 million, $4.9 million, and $4.3 million, respectively. At December 31, 2015, total unrecognized compensation cost related to non-vested stock options was approximately $249 thousand. This cost is expected to be recognized during the first quarter of 2016.

Restricted Share Units, Market Restricted Share Units, and Performance Share Units

Compensation expense is measured based on the grant date fair value of restricted share units, market restricted share units, and performance share units. The fair value of restricted share units and performance share units is equal to the market price of common stock on the grant date. The fair value of market restricted share units granted was estimated on the date of grant using a Monte Carlo simulation model with the following weighted average assumptions:

145

	2015		2014		2013
Risk-free interest rate	1.05	%	0.70	%	0.63	%
Expected stock price volatility	26.4		39.2		40.0

During the year ended December 31, 2015, Synovus granted 82,152 performance share units to senior management. These units have a grant date fair value of $28.06 and vest upon meeting certain service and performance conditions. During the year ended December 31, 2014, Synovus granted 67,157 performance share units with a grant date fair value of $23.47 to senior management. Return on average assets (ROAA) performance is evaluated each year over a three-year performance period, with share distribution determined at the end of the three years. The number of performance share units that will ultimately vest ranges from 0% to 150% of target based on Synovus' three-year weighted average ROAA (as defined).

Salary Stock Units and Other Information

During 2014 and 2013, Synovus also granted 44,527 and 70,015, respectively, salary stock units to senior management, which vested and were expensed immediately upon grant. Compensation expense was initially determined based on the number of salary stock units granted and the market price of common stock at the grant date. Subsequent to the grant date, compensation expense was recorded for changes in common stock market price. The total fair value of salary stock units granted during 2014 and 2013 was $1.2 million and $1.8 million, respectively. The salary stock units granted during 2014 were classified as liabilities and were settled in cash on January 15, 2015.

147

During 2015, Synovus recognized a share-based compensation net tax benefit of $1.7 million associated with vesting of restricted share units, stock option exercises, and expired stock options which was recorded as a component of additional paid-in capital within shareholders' equity. During 2014, Synovus recognized a net tax deficiency of $3.2 million associated primarily with expired stock options. The deficiency was recorded as a reduction of additional paid-in capital within shareholders' equity. During 2013, Synovus recognized a net tax benefit of $317 thousand. Synovus' future stock price will determine if a tax benefit is realized on outstanding stock options. If a tax benefit is not realized on outstanding stock options then the deferred tax asset associated with the outstanding stock options will be reduced with a corresponding tax deficiency recorded to additional paid-in capital.

The following table provides aggregate information regarding grants under all Synovus equity compensation plans through December 31, 2015.

The net decrease in the valuation allowance for the years ended December 31, 2015 and 2014 was $589 thousand and $2.3 million, respectively. The net decrease in the valuation allowance for the years ended December 31, 2015 and 2014 was due to expiring unused state credits.

Management assesses the realizability of deferred tax assets at each reporting period. The determination of whether a valuation allowance for deferred tax assets is appropriate is subject to considerable judgment and requires an evaluation of all the positive and negative evidence. At December 31, 2015, the Company is not in a three-year cumulative loss position; accordingly, it does not have significant negative evidence to consider when evaluating the realization of its deferred tax assets. Positive evidence supporting the realization of the Company’s deferred tax assets at December 31, 2015 includes generation of taxable income in 2015, 2014, and 2013, continued improvement in credit quality, record of long-term positive earnings prior to the most recent economic downturn, the Company’s strong capital position, as well as sufficient amounts of projected future taxable income, of the appropriate character, to support the realization of $511.9 million of the Company’s net deferred tax asset at December 31, 2015. The Company expects to realize its net deferred tax asset of $511.9 million at December 31, 2015 through the reversal of

149

existing taxable temporary differences and projected future taxable income. The valuation allowance of $11.7 million at December 31, 2015 relates to specific state income tax credits that have various expiration dates through the tax year 2019, and are expected to expire before they can be realized. Based on the assessment of all the positive and negative evidence at December 2015 and 2014, management has concluded that it is more likely than not that the results of future operations will generate sufficient taxable income to realize the deferred tax assets.

Synovus expects to realize substantially all of the $511.9 million in net deferred tax assets well in advance of the statutory carryforward period. At December 31, 2015, $155.6 million of existing deferred tax assets are not related to net operating losses or credits and therefore, have no expiration dates. $256.8 million of the remaining deferred tax assets relate to federal net operating losses which expire in years beginning in 2030 through 2032. Additionally, $51.8 million of the deferred tax assets relate to state net operating losses which will expire in installments annually through the tax year 2035. Tax credit carryforwards at December 31, 2015 include federal alternative minimum tax credits totaling $31.7 million which have an unlimited carryforward period. Other federal and state tax credits at December 31, 2015 total $27.7 million and have expiration dates through the tax year 2035.

Federal and state NOL and tax credit carryforwards as of December 31, 2015 are summarized in the following table.

Tax Carryforwards	As of December 31, 2015

Synovus is subject to income taxation in the United States and various state jurisdictions. Synovus' federal income tax return is filed on a consolidated basis, while state income tax returns are filed on both a consolidated and separate entity basis. Currently, there are no years for which Synovus filed a federal income tax return that are under examination by the IRS; however, a state tax examination from the Department of Revenue for Louisiana is currently in progress. Synovus is no longer subject to income tax examinations by the IRS for years before 2011, and excluding certain limited exceptions, Synovus is no longer subject to income tax examinations by state and local income tax authorities for years before 2011. However, amounts reported as net operating losses and tax credit carryovers from closed tax periods remain subject to review by most taxing authorities. Although Synovus is unable to determine the ultimate outcome of current and future examinations, Synovus believes that the liability recorded for uncertain tax positions is adequate.

Accrued interest and penalties related to unrecognized income tax benefits are included as a component of income tax expense. Accrued interest and penalties on unrecognized income tax benefits totaled $105 thousand and $96 thousand as of January 1 and December 31, 2015, respectively. Unrecognized income tax benefits as of January 1 and December 31, 2015 that, if recognized, would affect the effective income tax rate totaled $8.5 million and $8.3 million (net of the federal benefit on state income tax issues), respectively, which includes interest and penalties of $68 thousand and $63 thousand, respectively. Synovus expects that $320 thousand of uncertain income tax positions will be either settled or resolved during the next twelve months.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures. In connection with the preparation of this Annual Report on Form 10-K, an evaluation was carried out by Synovus' management, with the participation of Synovus' Chief Executive Officer and Chief Financial Officer, of the effectiveness of Synovus' disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (Exchange Act)). Disclosure controls and procedures are designed to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and that such information is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosures. Based on that evaluation, Synovus' Chief Executive Officer and Chief Financial Officer have concluded that, as of December 31, 2015, Synovus' disclosure controls and procedures were effective.

Synovus regularly engages in productivity and efficiency initiatives to streamline operations, reduce expenses, and increase revenue. Additionally, investment in new and updated information technology systems has enhanced information gathering and processing capabilities, and allowed management to operate in a more centralized environment for critical processing and monitoring functions. Management of Synovus is responsible for identifying, documenting, and evaluating the adequacy of the design and operation of the controls implemented during each process change described above. There have been no material changes in Synovus' internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during the period ended December 31, 2015 that has materially affected, or is reasonably likely to materially affect, Synovus' internal control over financial reporting.

Management's Report on Internal Control Over Financial Reporting. Management of Synovus is responsible for establishing and maintaining effective internal control over financial reporting for Synovus Financial Corp. and its subsidiaries (“we” and “our”), as that term is defined in Exchange Act Rules 13a-15(f). Synovus conducted an evaluation of the effectiveness of our internal control over Synovus' financial reporting as of December 31, 2015 based on criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on that evaluation, we concluded that our internal control over financial reporting is effective as of December 31, 2015.

KPMG LLP, an independent registered public accounting firm, has audited the consolidated financial statements included in this Annual Report and has issued a report on the effectiveness of our internal control over financial reporting, which report is included in "Part II - Item 8. Financial Statements and Supplementary Data" of this Report.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Note 1 - Summary of Significant Accounting Policies

Business Operations

The consolidated financial statements of Synovus include the accounts of the Parent Company and its consolidated subsidiaries. Synovus provides integrated financial services, including commercial and retail banking, financial management, insurance, and mortgage services to its customers through locally-branded divisions of its wholly-owned subsidiary bank, Synovus Bank, in offices located throughout Georgia, Alabama, South Carolina, Florida, and Tennessee.

In addition to our banking operations, we also provide various other financial services to our customers through direct and indirect wholly-owned non-bank subsidiaries, including: Synovus Securities, Inc., headquartered in Columbus, Georgia, which specializes in professional portfolio management for fixed-income securities, investment banking, the execution of securities transactions as a broker/dealer and the provision of individual investment advice on equity and other securities; Synovus Trust Company, N.A., headquartered in Columbus, Georgia, which provides trust, asset management and financial planning services; and Synovus Mortgage Corp., headquartered in Birmingham, Alabama, which offers mortgage services.

Basis of Presentation

The accounting and financial reporting policies of Synovus are in accordance with U.S. GAAP and conform to the accounting and reporting guidelines prescribed by bank regulatory authorities. All significant intercompany accounts and transactions have been eliminated in consolidation. In preparing the consolidated financial statements in accordance with U.S. GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the respective consolidated balance sheets and the reported amounts of revenues and expenses for the periods presented. Actual results could differ significantly from those estimates.

Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses; the valuation of other real estate; the fair value of investment securities; the fair value of private equity investments; contingent liabilities related to legal matters; and the deferred tax assets valuation allowance. In connection with the determination of the allowance for loan losses and the valuation of certain impaired loans and other real estate, management obtains independent appraisals for significant properties and properties collateralizing impaired loans. In making this determination, management also considers other factors or recent developments, such as changes in absorption rates or market conditions at the time of valuation and anticipated sales values based on management’s plans for disposition.

The following is a description of the Company's significant accounting policies.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash and due from banks. At December 31, 2015 and 2014, $100 thousand and $125 thousand, respectively, of the due from banks balance was restricted as to withdrawal.

Short-term Investments

Short-term investments consist of interest bearing funds with the Federal Reserve Bank, interest earning deposits with banks, and Federal funds sold and securities purchased under resale agreements. At December 31, 2015 and 2014, interest bearing funds with the Federal Reserve Bank included$117.3 million and $89.2 million, respectively, on deposit to meet Federal Reserve Bank reserve requirements. Interest earning deposits with banks include $2.2 million at December 31, 2015 and $7.1 million at December 31, 2014, which is pledged as collateral in connection with certain letters of credit. Federal funds sold include $65.9 million at December 31, 2015 and $67.5 million at December 31, 2014, which are pledged to collateralize certain derivative instruments. Federal funds sold and securities purchased under resale agreements, and Federal funds purchased and securities sold under repurchase agreements, generally mature in one day.

Trading Account Assets

Trading account assets, which are primarily held on a short-term basis for the purpose of selling at a profit, consist of debt and equity securities and are reported at fair value. Fair value adjustments and fees from trading account activities are included as a component of other fee income on the consolidated statements of income. Gains and losses realized from the sale of trading account assets are determined by specific identification and are included as a component of other fee income on the trade date. Interest income on trading assets is reported as a component of interest income on the consolidated statements of income.

Mortgage Loans Held for Sale and Mortgage Banking Income

Mortgage Loans Held for Sale

Mortgage loans held for sale are recorded at fair value. Fair value is derived from a hypothetical bulk sale model used to estimate the exit price of the loan in a loan sale. The bid pricing convention is used for loan pricing for similar assets. The valuation model is based upon forward settlements of a pool of loans of similar coupon, maturity, product, and credit attributes. The inputs to the model are continuously updated with available market and historical data. As the loans are sold in the secondary market, the valuation model produces an estimate of fair value that represents the highest and best use of the loans in Synovus' principal market.

Mortgage Banking Income

Mortgage banking income consists primarily of origination and ancillary fees on loans originated for sale, and gains and losses from the sale of mortgage loans. Mortgage loans are generally sold servicing released, without recourse or continuing involvement, and meet ASC 860-10-65, Transfers and Servicing of Financial Assets, criteria for sale accounting.

Other Loans Held for Sale

Loans are transferred to other loans held for sale at fair value when Synovus makes the determination to sell specifically identified loans. The fair value of the loans is primarily determined by analyzing the underlying collateral of the loan and the anticipated market prices of similar assets less estimated costs to sell. At the time of transfer, if the estimated fair value is less than the carrying amount, the difference is recorded as a charge-off against the allowance for loan losses. Decreases in the fair value subsequent to the transfer, as well as gains/losses realized from the sale of these assets, are recorded as losses on other loans held for sale, net, as a component of non-interest expense on the consolidated statements of income.

Investment Securities Available for Sale

Investment securities available for sale are carried at fair value with unrealized gains and losses, net of the related tax effect, excluded from earnings and reported as a separate component of shareholders' equity within accumulated other comprehensive income (loss) until realized.

Synovus performs a quarterly assessment of its investment securities available for sale to determine if the decline in fair value of a security below its amortized cost is deemed to be other-than-temporary. Factors included in the assessment include the length of time the security has been in a loss position, the extent that the fair value is below amortized cost, and the credit standing of the issuer. Other-than-temporary impairment losses are recognized on securities when: (1) the holder has an intention to sell the security; (2) it is more likely than not that the security will be required to be sold prior to recovery; or (3) the holder does not expect to recover the entire amortized cost basis of the security. Other-than-temporary impairment losses are reflected in earnings as realized losses to the extent the impairment is related to credit losses. The amount of the impairment related to other factors is recognized in other comprehensive income (loss).

Premiums and discounts are amortized or accreted over the life of the related security as an adjustment to yield using the effective interest method and prepayment assumptions. Actual prepayment experience is reviewed periodically and the timing of the accretion and amortization is adjusted accordingly. Interest income on securities available for sale is recorded on the accrual basis. Realized gains and losses for securities are included in investment securities gains (losses), net, on the consolidated statements of income and are derived using the specific identification method, on a trade date basis.

Loans and Interest Income on Loans

Loans are reported at principal amounts outstanding less amounts charged off, net of deferred fees and expenses. Interest income and deferred fees, net of expenses on loans, are recognized on a level yield basis.

Non-accrual Loans

Loans on which the accrual of interest has been discontinued are designated as non-accrual loans. Accrual of interest is discontinued on loans when reasonable doubt exists as to the full collection of interest or principal, or when loans become contractually past due for 90 days or more as to either interest or principal, in accordance with the terms of the loan agreement, unless they are both well-secured and in the process of collection. When a loan is placed on non-accrual status, previously accrued and uncollected interest is generally reversed as an adjustment to interest income on loans. Interest payments received on non-accrual loans are generally recorded as a reduction of principal. As payments are received on non-accruing loans, interest income can be recognized on a cash basis; however, there must be an expectation of full repayment of the remaining recorded principal balance. The remaining portion of this payment is recorded as a reduction to principal. Loans are generally returned to accruing status when they are brought fully current with respect to interest and principal and when, in the judgment of management, the loans are estimated to be fully collectible as to both principal and interest, and the borrower has sustained repayment performance under the terms of the loan agreement for a reasonable period of time (generally six months).

Impaired Loans

Impaired loans are loans for which it is probable that Synovus will not be able to collect all amounts due according to the contractual terms of the loan agreements and all loans modified in a troubled debt restructuring (TDR). Other than TDRs, impaired loans do not include smaller-balance homogeneous loans that are collectively evaluated for impairment, which consist of most retail loans and commercial loan relationships less than $1.0 million. Impairment is measured on a discounted cash flow method based upon the loan's contractual effective interest rate, or at the loan's observable market price, or at the fair value of the collateral, less costs to sell if the loan is collateral-dependent. Interest income on non-accrual impaired loans is recognized as described above under "non-accrual loans." Impaired accruing loans generally consist of those troubled debt restructurings for which management has concluded that the collectability of the loan is not in doubt.

At December 31, 2015, substantially all non-accrual impaired loans were collateral-dependent and secured by real estate. For impairment measured using the estimated fair value of collateral less costs to sell, fair value is estimated using appraisals performed by a certified or licensed appraiser. Management also considers other factors or recent developments, such as selling costs and anticipated sales values, taking into account management's plans for disposition, which could result in adjustments to the fair value estimates indicated in the appraisals. The assumptions used in determining the amount of the impairment are subject to significant judgment. Use of different assumptions, for example, changes in the fair value of the collateral or management's plans for disposition could have a significant impact on the amount of impairment.

Under the discounted cash flow method, impairment is recorded as a specific reserve with a charge-off for any portion of the impairment considered a confirmed loss. The reserve is reassessed each quarter and adjusted as appropriate based on changes in estimated cash flows.

Where guarantors are determined to be a source of repayment, an assessment of the guarantee is required. This guarantee assessment would include, but not be limited to, factors such as type and feature of the guarantee, consideration for the guarantor's financial strength and capacity to service the loan in combination with the guarantor's other financial obligations as well as the guarantor's willingness to assist in servicing the loan.

Troubled Debt Restructurings

When borrowers are experiencing financial difficulties, Synovus may, in order to assist the borrowers in repaying the principal and interest owed to Synovus, make certain modifications to the borrower's loan. All loan modifications and renewals are evaluated for troubled debt restructuring (TDR) classification. In accordance with ASU 2011-02, A Creditor's Determination of Whether a Restructuring is a Troubled Debt Restructuring, a TDR is defined as a modification with a borrower that is experiencing financial difficulties, and the creditor has granted a financial concession that it would not normally make. The market interest rate concept in ASU 2011-02 states that if a borrower does not otherwise have access to funds at a market interest rate for debt with characteristics similar to those of the restructured debt, the restructuring would be considered to be at a below-market rate, which indicates that the lender may have granted a concession. Since Synovus often increases or maintains the interest rate upon renewal of a commercial loan, including renewals of loans involving borrowers experiencing financial difficulties, the market rate concept has become a significant factor in determining if a loan is classified as a TDR. All TDRs are considered to be impaired loans, and the amount of impairment, if any, is determined in accordance with ASC 310-10-35, Accounting by Creditors for Impairment of a Loan-an amendment of FASB Statements No. 5, ASC 450-20, and No. 15, ASC 310-40.

Concessions provided by Synovus in a TDR are generally made in order to assist borrowers so that debt service is not interrupted and to mitigate the potential for loan losses. A number of factors are reviewed when a loan is renewed, refinanced, or modified, including cash flows, collateral values, guarantees, and loan structures. Concessions are primarily in the form of providing a below market interest rate given the borrower's credit risk to assist the borrower in managing cash flows, an extension of the maturity of the loan generally for less than one year, or a period of time generally less than one year with a reduction of required principal and/or interest payments (e.g., interest only for a period of time). These types of concessions may be made during the term of a loan or upon the maturity of a loan, as a loan renewal. Renewals of loans made to borrowers experiencing financial difficulties are evaluated for TDR designation by determining if concessions are being granted, including consideration of whether the renewed loan has an interest rate that is at market, given the credit risk related to the loan. Insignificant periods of reduction of principal and/or interest payments, or one time deferrals of three months or less, are generally not considered to be financial concessions. Further, it is generally Synovus' practice not to defer principal and/or interest for more than twelve months.

These types of concessions may be made during the term of a loan or upon the maturity of a loan, in which the borrower is experiencing financial difficulty, as a loan renewal.

Renewals of loans made to borrowers experiencing financial difficulties are evaluated for TDR designation by determining if concession(s) are being granted, including consideration of whether the renewed loan has an interest rate that is at market, given the credit risk related to the loan.

Non-accruing TDRs may generally be returned to accrual status if there has been a period of performance, usually at least a six month sustained period of repayment performance by the borrower. Consistent with regulatory guidance, a TDR will generally no longer be reported as a TDR after a period of performance and after the loan was reported as a TDR at a year-end reporting date, and if at the time of the modification, the interest rate was at market, considering the credit risk associated with the borrower.

Allowance for Loan Losses

The allowance for loan losses is a significant accounting estimate that is determined through periodic and systematic detailed reviews of the Company’s loan portfolio. These reviews are performed to assess the probable incurred losses within the portfolio and to ensure consistency between fluctuations in the allowance and both credit events within the portfolio and prevailing credit trends. The economic and business climate in any given industry or market is difficult to gauge and can change rapidly, and the effects of those changes can vary by borrower. Significant judgments and estimates are necessary in the determination of the allowance for loan losses. Significant judgments include, among others, loan risk ratings and classifications, the determination and measurement of impaired loans, the timing of loan charge-offs, the probability of loan defaults, the net loss exposure in the event of loan defaults, the loss emergence period, qualitative loss factors, management’s plans, if any, for disposition of certain loans, as well as other qualitative considerations. In determining the allowance for loan losses, management makes numerous assumptions, estimates, and assessments, which are inherently subjective. The use of different estimates or assumptions could have a significant impact on the provision for loan losses, allowance for loan losses, non-performing loans, loan charge-offs and the Company's consolidated financial condition and results of operations.

The allocated allowance is based upon quarterly analyses of impaired commercial loans to determine the amount of specific reserves (and/or loan charge-offs), if any, as well as an analysis of historical loan default experience, loan net loss experience, loss emergence experience, and related qualitative factors, if appropriate, for categories of loans with similar risk attributes and further segregated by Synovus' internal loan grading system.

Impaired loans are generally evaluated on a loan by loan basis with specific reserves, if any, recorded as appropriate. Specific reserves are determined based on ASC 310-10-35, which provides for measurement of a loan's impairment based on one of three methods. If the loan is collateral-dependent, then the fair value of the loan's collateral, less estimated selling costs, are compared to the loan's carrying amount to determine impairment. Other methods of measuring a loan's impairment include the present value of the expected future cash flows of the loan, or if available, the observable market price of the loan. Synovus considers the pertinent facts and circumstances for each impaired loan when selecting the appropriate method to measure impairment, and quarterly evaluates each selection to ensure its continued appropriateness and evaluates the reasonableness of specific reserves, if any.

For loans that are not considered impaired, the allocated allowance for loan losses is determined based upon Expected Loss (EL) factors, which are applied to groupings of specific loan types by loan risk ratings. The EL is determined based upon a probability of default (PD), which is the probability that a borrower, segregated by loan type and loan risk grade, will default, and loss given default (LGD), which is the estimate of the amount of net loss in the event of default. The groupings of the loans into loan categories are determined based upon the nature of the loan types and the level of inherent risk associated with the various loan categories. The loan groupings are further segregated based upon the individual loan risk ratings, as described below. The EL factors applied in the methodology are periodically re-evaluated and adjusted to reflect changes in historical loss levels or other risks.

Allocated EL factors may also be adjusted, as necessary, for certain qualitative factors that in management's judgment are necessary to reflect losses incurred in the portfolio.

Qualitative factors that management considers in the analysis include:

• changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses

• changes in the volume and severity of past due loans, the volume of non-accrual loans, and the volume and severity of adversely classified or grade loans

• loan growth

• effects of changes in credit concentrations

• experience, ability, and depth of lending management, loan review personnel, and other relevant staff

• changes in the quality of the loan review function

• national and local economic trends and conditions

• value of underlying collateral for collateral-dependent loans

• other external factors such as the effects for the current competitive, legal, and regulatory environment

The adjusted EL factors by portfolio are then adjusted by a loss emergence period for each loan type. A loss emergence period represents the amount of time between when a loss event first occurs to when it is charged off. The loss emergence period was determined for each loan type based on the Company's historical experience and is validated annually.

Commercial Loans - Risk Ratings

Synovus utilizes two primary methods for risk assessment of the commercial loan portfolio: Single Risk Rating Assessment and Dual Risk Rating (DRR) Assessment. The single and dual risk ratings are based on the borrowers' credit risk profile, considering factors such as debt service history, current and estimated prospective cash flow information, collateral supporting the credit, source of repayment as well as other variables, as appropriate.

Each loan is assigned a risk rating during its initial approval process. For single risk rated loans, this process begins with a loan rating recommendation from the loan officer responsible for originating the loan. Commercial single risk rated loans are graded on a 9-point scale. Single risk ratings six through nine are defined consistent with the bank regulatory classifications of special mention, substandard, doubtful, and loss, respectively. The primary determinants of the risk ratings for commercial single risk rated loans are the reliability of the primary source of repayment and the borrower's expected performance (i.e., the likelihood that the borrower will be able to service its obligations in accordance with the terms). Expected performance will be based upon full analysis of the borrower's historical financial results, current financial strength and future prospects, which includes any external drivers.

For dual risk rated loans, this process begins with scoring the loan for a rating during its initial approval process. Synovus began utilizing a dual risk rating methodology for certain components of its commercial and industrial loan portfolio in 2013 and extended the DRR methodology to certain income-producing real estate loans in 2014 and 2015. The DRR includes sixteen probabilities of default categories and nine categories for estimating losses given an event of default. The result is an expected loss rate established for each borrower.

The loan rating is subject to approvals from other members of management, regional credit and/or loan committees depending on the size of the loan and loan's credit attributes. Loan ratings are regularly re-evaluated based upon annual scheduled credit reviews or on a more frequent basis if determined prudent by management.Additionally, an independent loan review function evaluates Synovus' risk rating processes on a continuous basis.

Management currently expects to implement the DRR methodology for additional components of the commercial loan portfolio over the next few years. The implementation is expected to be in multiple phases, with each component determined based primarily on loan type and size. The timing of future implementations will depend upon completion of applicable data analysis and model assessment. Once full implementation is completed, management estimates that the DRR methodology will be utilized to calculate the allowance for loan losses on commercial loans amounting to approximately 35% of the total loan portfolio. Approximately $6.7 billion, or 29.8%, of the total loan portfolio was rated using the DRR methodology at year-end 2015.

Retail Loans – Risk Ratings

Retail loans are generally assigned a risk rating on a 6-point scale at the time of origination based on credit bureau scores, with a loan grade of 1 assigned as the lowest level of risk and a loan grade of 6 as the highest level of risk. At 90-119 days past due, a loan grade of 7-substandard rating is applied and at 120 days past due, the loan is generally downgraded to grade 9-loss and is generally charged-off. The credit bureau-based ratings are updated at least semi-annually and the ratings based on the past due status are updated monthly.

Unallocated Allowance for Loan Losses

The unallocated component of the allowance for loan losses is not a significant component of the ALLL, but would be utilized to provide for certain environmental and economic factors that affect the inherent risk of loss in the entire loan portfolio that are not fully captured in the allocated allowance for loan losses. On a quarterly basis, management updates its analysis and consideration of these factors and determines the impact, if any, on the allowance for loan losses and the provision for loan losses for each respective period.

Premises and Equipment

Premises and equipment, including bank owned branch locations and leasehold improvements, are reported at cost, less accumulated depreciation and amortization, which are computed using the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are depreciated over the shorter of the estimated useful life or the remainder of the lease term. Synovus reviews long-lived assets, such as premises and equipment, for impairment whenever events and circumstances indicate that the carrying amount of an asset may not be recoverable.

Goodwill

Goodwill represents the excess purchase price over the fair value of identifiable net assets of acquired businesses. In accordance with ASC 350, Intangibles, Goodwill and Other, goodwill is not amortized, but tested for impairment at the reporting unit (sub-segment) level on an annual basis and as events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Synovus reviews goodwill for impairment as of June 30^th and at interim periods if indicators of impairment exist.

Significant judgment is applied when goodwill is assessed for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, incorporating general economic and market conditions, and selecting an appropriate control premium. The selection and weighting of the various fair value techniques may result in a higher or lower fair value. Judgment is applied in determining the weighting that are most representative of fair value.

Other Real Estate

Other Real Estate (ORE) consists of properties obtained through a foreclosure proceeding or through an in-substance foreclosure in satisfaction of loans. In accordance with the provisions of ASC 310-10-35 regarding subsequent measurement of loans for impairment and ASC 310-40-15 regarding accounting for troubled debt restructurings by a creditor, a loan is classified as an in-substance foreclosure when Synovus has taken possession of the collateral regardless of whether formal foreclosure proceedings have taken place.

At foreclosure, ORE is recorded at the lower of cost or fair value less estimated selling costs, which establishes a new cost basis. Subsequent to foreclosure, ORE is evaluated quarterly and reported at fair value less estimated selling costs, not to exceed the new cost basis, determined by review of current appraisals, as well as the review of comparable sales and other estimates of fair value obtained principally from independent sources, adjusted for estimated selling costs. Management also considers other factors or recent developments such as changes in absorption rates or market conditions from the time of the latest appraisal received or previous re-evaluation performed, and anticipated sales values considering management's plans for disposition, which could result in an adjustment to lower the fair value estimates indicated in the appraisals. At the time of foreclosure or initial possession of collateral, any excess of the loan balance over the fair value of the real estate held as collateral, less costs to sell, is recorded as a charge against the allowance for loan losses. Revenue and expenses from ORE operations as well as gains or losses on sales are recorded as foreclosed real estate expense, net, a component of non-interest expense on the consolidated statements of income. Subsequent declines in fair value are recorded on a property-by-property basis through use of a valuation allowance within other real estate on the consolidated balance sheets and valuation adjustment account in foreclosed real estate expense, net, a component of non-interest expense on the consolidated statements of income.

Synovus' objective is to dispose of ORE properties in a timely manner and to maximize net sale proceeds. Synovus has a centralized managed assets division, with the specialized skill set to facilitate this objective. While there is not a defined timeline for their sale, ORE properties are actively marketed through unaffiliated third parties.

Other Assets

Other assets include accrued interest receivable and other significant balances as described below.

Investments in Company-Owned Life Insurance Policies

Investments in company-owned life insurance policies on certain current and former officers of Synovus are recorded at the net realizable value of the policies as a component of other assets in the consolidated balance sheets. Net realizable value is the cash surrender value of the policies less any applicable surrender charges and any policy loans. Synovus has not borrowed against the cash surrender value of these policies. The changes in the cash surrender value of the policies is recognized as a component of other non-interest income in the consolidated statements of income.

Servicing Asset on SBA/Government Guaranteed Loans

Synovus has retained servicing responsibilities on sold SBA/government guaranteed loans and receives annual servicing fees on the outstanding loan balances.  SBA/government guaranteed loan servicing rights are accounted for using the amortization method.  A servicing asset is established at fair value at the time of the sale using a discounted future cash flow model.  The servicing asset is then amortized in other non-interest expense.

Private Equity Investments

Private equity investments are recorded at fair value on the consolidated balance sheets with realized and unrealized gains and losses recorded on the consolidated statements of income (as a component of other non-interest income) in accordance with ASC 946, Financial Services-Investment Companies. The private equity investments in which Synovus holds a limited partner interest consist of funds that invest in privately held companies. For privately held companies in the fund, the general partner estimates the fair value of the company in accordance with U.S. GAAP as clarified by ASC 820, Fair Value Measurements and Disclosures. The estimated fair value of the company is the estimated fair value as an exit price the fund would receive if it were to sell the company in the marketplace. The fair value of the fund's underlying investments is estimated through the use of valuation models, such as option pricing or a discounted cash flow model. Valuation factors, such as a company's financial performance against budget or milestones, last price paid by investors, with consideration given on whether financing is provided by insiders or unrelated new investors, public market comparables, liquidity of the market, industry and economic trends, and changes in management or key personnel, are used in the determination of estimated fair value.

Derivative Instruments

Synovus’ risk management policies emphasize the management of interest rate risk within acceptable guidelines. Synovus’ objective in maintaining these policies is to limit volatility in net interest income arising from changes in interest rates. Risks to be managed include both fair value and cash flow risks. Utilization of derivative financial instruments provides a valuable tool to assist in the management of these risks.

In accordance with ASC 815, Derivatives and Hedging, all derivative instruments are recorded on the consolidated balance sheets at their respective fair values, as components of other assets and other liabilities. The accounting for changes in fair value (i.e., unrealized gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and, if so, on the reason for holding it. If certain conditions are met, entities may elect to designate a derivative instrument as a hedge of exposures to changes in fair values, cash flows, or foreign currencies. If the hedged exposure is a fair value exposure, the unrealized gain or loss on the derivative instrument is recognized in earnings in the period of change, together with the offsetting unrealized loss or gain on the hedged item attributable to the risk being hedged as a component of other non-interest income on the consolidated statements of income. If the hedged exposure is a cash flow exposure, the effective portion of the gain or loss on the derivative instrument is reported initially as a component of accumulated other comprehensive income (loss), net of the tax impact, and subsequently reclassified into earnings when the hedged transaction affects earnings. Any amounts excluded from the assessment of hedge effectiveness, as well as the ineffective portion of the gain or loss on the derivative instrument, are reported in earnings immediately as a component of other non-interest income on the consolidated statements of income. If the derivative instrument is not designated as a hedge, the gain or loss on the derivative instrument is recognized in earnings as a component of other non-interest income on the consolidated statements of income in the period of change.

With the exception of certain commitments to fund and sell fixed-rate mortgage loans and derivatives utilized to meet the financing and interest rate risk management needs of its customers, all derivatives utilized by Synovus to manage its interest rate sensitivity are designated as either a hedge of a recognized fixed-rate asset or liability (fair value hedge), or a hedge of a forecasted transaction or of the variability of future cash flows of a floating rate asset or liability (cash flow hedge). Synovus does not speculate using derivative instruments.

In 2005, Synovus entered into certain forward starting swap contracts to hedge the cash flow risk of certain forecasted interest payments on a forecasted debt issuance. Upon the determination to issue debt, Synovus was potentially exposed to cash flow risk due to changes in market interest rates prior to the placement of the debt. The forward starting swaps allowed Synovus to hedge this exposure. Upon placement of the debt, these swaps were cash settled concurrent with the pricing of the debt. The effective portion of the cash flow hedge included in accumulated other comprehensive income is being amortized over the life of the debt issue as an adjustment to interest expense.

Synovus also holds derivative instruments, which consist of rate lock agreements related to expected funding of fixed-rate mortgage loans to customers (interest rate lock commitments) and forward commitments to sell mortgage-backed securities and individual fixed-rate mortgage loans. Synovus’ objective in obtaining the forward commitments is to mitigate the interest rate risk associated with the interest rate lock commitments and the mortgage loans that are held for sale. Both the interest rate lock commitments and the forward commitments are reported at fair value, with adjustments recorded in current period earnings in mortgage banking income.

Synovus also enters into interest rate swap agreements to facilitate the risk management strategies of certain commercial banking customers. Synovus mitigates this risk by entering into equal and offsetting interest rate swap agreements with highly rated third-party financial institutions. The interest rate swap agreements are free-standing derivatives and are recorded at fair value with any unrealized gain or loss recorded in current period earnings in other non-interest income. These instruments, and their offsetting positions, are recorded in other assets and other liabilities on the consolidated balance sheets.

When using derivatives to hedge fair value and cash flow risks, Synovus exposes itself to potential credit risk from the counterparty to the hedging instrument. This credit risk is generally a small percentage of the notional amount and fluctuates as interest rates change. Synovus analyzes and approves credit risk for all potential derivative counterparties prior to execution of any derivative transaction. Synovus seeks to minimize credit risk by dealing with highly rated counterparties and by obtaining collateralization for exposures above certain predetermined limits. If significant counterparty risk is determined, Synovus adjusts the fair value of the derivative recorded asset balance to consider such risk.

Non-interest Income

Service Charges on Deposit Accounts

Service charges on deposit accounts consist of non-sufficient funds fees, account analysis fees, and other service charges on deposits which consist primarily of monthly account fees. Non-sufficient funds fees are recognized at the time when the account overdraft occurs in accordance with regulatory guidelines. Account analysis fees consist of fees charged to certain commercial demand deposit accounts based upon account activity (and reduced by a credit which is based upon cash levels in the account). These fees, as well as monthly account fees, are recorded under the accrual method of accounting.

Fiduciary and Asset Management Fees

Fiduciary and asset management fees are generally determined based upon fair values of assets under management as of a specified date during the period. These fees are recorded under the accrual method of accounting as the services are performed.

Brokerage and Investment Banking Revenue

Brokerage revenue consists primarily of commission income, which represents the spread between buy and sell transactions processed, and net fees charged to customers on a transaction basis for buy and sell transactions processed. Commission income is recorded on a trade-date basis. Brokerage revenue also includes portfolio management fees, which represent monthly fees charged on a contractual basis to customers for the management of their investment portfolios and are recorded under the accrual method of accounting.

Investment banking revenue represents fees for services arising from securities offerings or placements in which Synovus acts as an agent. It also includes fees earned from providing advisory services. Revenue is recognized at the time the underwriting is completed and the revenue is reasonably determinable.

Bankcard Fees

Bankcard fees consist primarily of interchange fees earned, net of fees paid, on debit card and credit card transactions. Net fees are recognized into income as they are collected.

Advertising Costs

Advertising costs are expensed as incurred and recorded as a component of non-interest expense.

Income Taxes

Synovus is a domestic corporation that files a consolidated federal income tax return with its wholly-owned subsidiaries and files state income tax returns on a consolidated and a separate entity basis with the various taxing jurisdictions based on its taxable presence. Synovus accounts for income taxes in accordance with ASC 740, Income Taxes. The current income tax accrual or receivable is an estimate of the amounts owed to or due from taxing authorities in which Synovus conducts business. It also includes increases and decreases in the amount of taxes payable for uncertain tax positions reported in tax returns for the current and/or prior years.

Synovus uses the asset and liability method to account for future income taxes expected to be paid or received (i.e., deferred income taxes). Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement (GAAP) carrying amounts of existing assets and liabilities and their respective tax bases, including operating losses and tax credit carryforwards. The deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in income tax rates is recognized in income in the period that includes the enactment date.

A valuation allowance is required for deferred tax assets if, based on available evidence, it is more likely than not that all or some portion of the asset will not be realized. In making this assessment, all sources of taxable income available to realize the deferred tax asset are considered, including taxable income in prior carryback years, future reversals of existing temporary differences, tax planning strategies, and future taxable income exclusive of reversing temporary differences and carryforwards. The predictability that future taxable income, exclusive of reversing temporary differences, will occur is the most subjective of these four sources. Changes in the valuation allowance are recorded through income tax expense.

Significant estimates used in accounting for income taxes relate to the valuation allowance for deferred tax assets, estimates of the realizability of income tax credits, utilization of net operating losses, the determination of taxable income, and the determination of temporary differences between book and tax bases.

Synovus accrues tax liabilities for uncertain income tax positions based on current assumptions regarding the expected outcome by weighing the facts and circumstances available at the reporting date. If related tax benefits of a transaction are not more likely than not of being sustained upon examination, Synovus will accrue a tax liability or reduce a deferred tax asset for the expected tax impact associated with the transaction. Events and circumstances may alter the estimates and assumptions used in the analysis of its income tax positions and, accordingly, Synovus' effective tax rate may fluctuate in the future. Synovus recognizes accrued interest and penalties related to unrecognized income tax benefits as a component of income tax expense.

Share-based Compensation

Synovus has a long-term incentive plan under which the Compensation Committee of the Board of Directors has the authority to grant share-based awards to Synovus employees. Synovus' share-based compensation costs associated with employee grants are recorded as a component of salaries and other personnel expense in the consolidated statements of income. Share-based compensation costs associated with grants made to non-employee directors of Synovus are recorded as a component of other operating expenses. Share-based compensation expense for service-based awards that contain a graded vesting schedule is recognized net of estimated forfeitures for plan participants on a straight-line basis over the requisite service period for the entire award.

Earnings per Share

Basic net income per common share is computed by dividing net income available to common shareholders by the average common shares outstanding for the period. Diluted net income per common share reflects the dilution that could occur if securities or other contracts to issue common stock were exercised or converted. The dilutive effect of outstanding options and restricted share units is reflected in diluted net income per common share, unless the impact is anti-dilutive, by application of the treasury stock method.

All share and per share amounts for all periods presented in this Report reflect the one-for-seven reverse stock split, which was effective on May 16, 2014.

Fair Value Measurements and Disclosures

Fair value estimates are made at a specific point in time, based on relevant market information and other information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale, at one time, the entire holdings of a particular financial instrument. Because no market exists for a portion of the financial instruments, fair value estimates are also based on judgments regarding estimated cash flows, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Synovus employs independent third-party pricing services to provide fair value estimates for its investment securities available for sale, trading account assets, and derivative financial instruments. Fair values for fixed income investment securities and certain derivative financial instruments are typically the prices supplied by either the third-party pricing service or an unrelated counterparty, which utilize quoted market prices, broker/dealer quotations for identical or similar securities, and/or inputs that are observable in the market, either directly or indirectly, for substantially similar securities. Level 1 securities are typically exchange quoted prices. Level 2 securities are typically matrix priced by a third-party pricing service to calculate the fair value. Such fair value measurements consider observable data, such as relevant broker/dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayments speeds, credit information, and the respective terms and conditions for debt instruments. Level 3 instruments' value is determined using pricing models, discounted cash flow models and similar techniques, and may also include the use of market prices of assets or liabilities that are not directly comparable to the subject asset or liability. These methods of valuation may result in a significant portion of the fair value being derived from unobservable assumptions that reflect Synovus' own estimates for assumptions that market participants would use in pricing the asset or liability.

Management uses various validation procedures to validate the prices received from pricing services and quotations received from dealers are reasonable for each relevant financial instrument, including reference to relevant broker/dealer quotes or other market quotes and a review of valuations and trade activity of comparable securities. Consideration is given to the nature of the quotes (e.g., indicative or firm) and the relationship of recently evidenced market activity to the prices provided by the third-party pricing service. Further, management also employs the services of an additional independent pricing firm as a means to verify and confirm the fair values of its primary independent pricing firm.

Understanding the third-party pricing service's valuation methods, assumptions and inputs used by the firm is an important part of the process of determining that reasonable and reliable fair values are being obtained. Management evaluates quantitative and qualitative information provided by the third-party pricing services to assess whether they continue to exhibit the high level of expertise and internal controls that management relies upon.

Fair value estimates are based on existing financial instruments on the consolidated balance sheet, without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Significant assets and liabilities that are not considered financial instruments include deferred income taxes, premises and equipment, equity method investments, goodwill and other intangible assets. In addition, the income tax ramifications related to the realization of the unrealized gains and losses on available for sale investment securities and cash flow hedges can have a significant effect on fair value estimates and have not been considered in any of the estimates.

Contingent Liabilities and Legal Costs

Synovus estimates its contingent liabilities with respect to outstanding legal matters based on information currently available to management, management’s estimates about the probability of outcomes of each case and the advice of legal counsel. In accordance with guidance in ASC 450-25-2, management accrues an estimated loss from a loss contingency when information available indicates that it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. In addition, it must be probable that one or more future events will occur confirming the fact of the loss. Significant judgment is required in making these estimates and management must make assumptions about matters that are highly uncertain. Accordingly, the actual loss may be more or less than the current estimate.

In many situations, Synovus may be unable to estimate reasonably possible losses due to the preliminary nature of the legal matters, as well as a variety of other factors and uncertainties. As there are further developments, Synovus will reassess these legal matters and the related potential liabilities and will revise, when needed, its estimate of contingent liabilities.

Legal costs, including attorney fees, incurred in connection with pending litigation and other loss contingencies are expensed as incurred.

Recently Adopted Accounting Standards Updates

In January 2014, the FASB issued amended guidance, ASU 2014-01, Investments-Equity Method and Joint Ventures (Topic 323), Accounting for Investments in Qualified Affordable Housing Projects, which permits Synovus to make an accounting policy election to account for its investments in qualified affordable housing projects using a proportional amortization method, if certain conditions are met, and to present the amortization as a component of income tax expense. The amended guidance would be applied retrospectively to all periods presented and is effective for fiscal years, and interim periods within those years, beginning after December 15, 2014. Regardless of the policy election, the amended guidance, where disclosed, enables users of the financial statements to understand the nature of investments in qualified affordable housing projects and the effect of the measurement of the investments in qualified affordable housing projects and the related tax credits on Synovus' financial position and results of operations.

Synovus adopted the amended guidance on January 1, 2015, and did not make an accounting policy election to apply the proportional amortization method for its investments in qualified affordable housing projects because the impact to the consolidated financial statements was insignificant. Therefore, the adoption did not have an impact on Synovus' consolidated financial statements. At December 31, 2015, the aggregate carrying value of Synovus' investments in LIHTC partnerships was $18.9 million. See Note 16 "Variable Interest Entities" to the consolidated financial statements of Synovus' 2015 Form 10-K for additional information regarding these investments.

Synovus early adopted ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs, during the the fourth quarter of 2015. This ASU was issued to simplify the presentation of debt issuance costs. Under previous accounting standards, debt issuance costs were reported on the balance sheet as assets and amortized as interest expense. ASU 2015-03 requires that debt issuance costs be presented on the balance sheet as a direct deduction from the carrying amount of the related liability, which is similar to the presentation of debt discounts or premiums. The costs will continue to be amortized to interest expense using the effective interest method. The cost of issuing debt will no longer be recorded as a separate asset, except when incurred before receipt of the funding from the associated debt liability. All prior periods presented in this Report have been adjusted to reflect adoption of ASU 2015-03 with updates to long-term debt and other assets. Adoption of ASU 2015-03 did not have a material impact on Synvous' consolidated financial statements.

Additionally, adoption of the following standards effective January 1, 2015, did not have a significant impact on Synovus' consolidated financial statements:

•ASU 2014-14, Classification of Certain Government-Guaranteed Mortgage Loans Upon Foreclosure

•ASU 2014-12, Accounting for Share-Based Payments when the Terms of an Award Provide that a Performance

Target Could be Achieved after the Requisite Service Period

•ASU 2014-11, Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures

•ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity

•ASU 2014-04, Receivables-Troubled Debt Restructurings by Creditors (Subtopic 310-40), Reclassification of

Residential Real Estate Collateralized Consumer Mortgage Loans Upon Foreclosure

ŸASU 2015-05, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-

Credit Arrangements

Recently Issued Accounting Standards Updates

The following ASUs will be implemented effective January 1, 2016 or later:

ASU 2014-09, "Revenue from Contracts with Customers" - ASU 2014-09 establishes a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The standard is intended to increase comparability across industries and jurisdictions. The core principle of the revenue model is that a company will recognize revenue when it transfers control of goods or services to customers at an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services.

The FASB issued ASU 2015-14, Revenue From Contracts with Customers – Deferral of the Effective Date, in August 2015 to defer the effective date of ASU 2014-09 for one year. The proposed new effective date will be annual reporting periods beginning after December 15, 2017, and interim periods within that year, for public business entities. As such, for Synovus, the ASU will be effective on January 1, 2018. Earlier application will be permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period.

Management is currently evaluating the impact of ASU 2014-09 on Synovus' consolidated financial statements. The standard is expected to potentially impact ORE sales, interchange revenue, credit card loyalty programs, uncollectible credit card interest and fees, asset managers’ performance fees, treasury management services revenue, and miscellaneous fees; however the overall

financial statement impact for Synovus is not expected to be material. Extensive new disclosures will be required, including disaggregation of total revenue, information about performance obligations, changes in contract asset and liability account balances

ASU 2015-02, "Amendments to the Consolidation Analysis" - ASU 2015-02 was issued by the FASB to modify the analysis that companies must perform in order to determine whether a legal entity should be consolidated. ASU 2015-02 simplifies current consolidation rules by reducing the number of consolidation models; placing more emphasis on risk of loss when determining a controlling financial interest; reducing the frequency of the application of related-party guidance when determining a controlling financial interest in a variable interest entity (VIE); and changing consolidation conclusions for public and private companies in several industries that typically make use of limited partnerships or VIEs. ASU 2015-02 will be effective for the first quarter of 2016 for Synovus. Management does not expect the adoption of this ASU to have a material impact on the consolidated financial statements of Synovus.

Reclassifications

Prior years' consolidated financial statements are reclassified whenever necessary to conform to the current year's presentation.

Subsequent Events

Synovus has evaluated for consideration, or disclosure, all transactions, events, and circumstances, subsequent to the date of the consolidated balance sheet and through the date the accompanying audited consolidated financial statements were issued, and has reflected, or disclosed, those items deemed appropriate within the consolidated financial statements and related footnotes.

⁽¹⁾  Amortized cost is adjusted for other-than-temporary impairment charges in 2014, which have been recognized in the consolidated statements of income, and were considered inconsequential.

At December 31, 2015 and 2014, investment securities with a carrying value of $2.43 billion and $2.12 billion, respectively, were pledged to secure certain deposits and securities sold under repurchase agreements as required by law and contractual agreements.

Synovus has reviewed investment securities that are in an unrealized loss position as of December 31, 2015 and 2014 for OTTI and does not consider any securities in an unrealized loss position to be other-than-temporarily impaired. If Synovus intended to sell a security in an unrealized loss position, the entire unrealized loss would be reflected in income. Synovus does not intend to sell investment securities in an unrealized loss position prior to the recovery of the unrealized loss, which may be until maturity, and has the ability and intent to hold those securities for that period of time. Additionally, Synovus is not currently aware of any circumstances which will require it to sell any of the securities that are in an unrealized loss position prior to the respective securities recovery of all such unrealized losses.

Declines in the fair value of available for sale securities below their cost that are deemed to have OTTI are reflected in earnings as realized losses to the extent the impairment is related to credit losses. The amount of the impairment related to other factors is recognized in other comprehensive income. Currently, unrealized losses on debt securities are attributable to increases in interest rates on comparable securities from the date of purchase. Synovus regularly evaluates its investment securities portfolio to ensure that there are no conditions that would indicate that unrealized losses represent OTTI. These factors include the length of time the security has been in a loss position, the extent that the fair value is below amortized cost, and the credit standing of the issuer. As of December 31, 2015, Synovus had sixty-four investment securities in a loss position for less than twelve months and twenty-nine investment securities in a loss position for twelve months or longer.

Gross unrealized losses on investment securities and the fair value of the related securities, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, at December 31, 2015 and December 31, 2014 are presented below.

The amortized cost and fair value by contractual maturity of investment securities available for sale at December 31, 2015 are shown below. The expected life of mortgage-backed securities or CMOs may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. For purposes of the maturity table, mortgage-backed securities and CMOs, which are not due at a single maturity date, have been classified based on the final contractual maturity date.

⁽²⁾ Total before net deferred fees and costs of $30.8 million.

Non-accrual loans as of December 31, 2015 and 2014 were $168.4 million and $197.8 million, respectively. Interest income on non-accrual loans outstanding at December 31, 2015 and 2014 that would have been recorded if the loans had been current and performed in accordance with their original terms was $10.5 million and $12.6 million, respectively. Interest income recorded on these loans for the years ended December 31, 2015 and 2014 was $4.3 million and $4.1 million, respectively.

The credit quality of the loan portfolio is summarized no less frequently than quarterly using the standard asset classification system utilized by the federal banking agencies. These classifications are divided into three groups – Not Classified (Pass), Special Mention, and Classified or Adverse rating (Substandard, Doubtful, and Loss) and are defined as follows:

Pass- loans which are well protected by the current net worth and paying capacity of the obligor (or guarantors, if any) or by the fair value, less cost to acquire and sell, of any underlying collateral in a timely manner.

Special Mention - loans which have potential weaknesses that deserve management's close attention. These loans are not adversely classified and do not expose an institution to sufficient risk to warrant an adverse classification.

Substandard - loans which are inadequately protected by the current net worth and paying capacity of the obligor or by the collateral pledged, if any. Loans with this classification are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.

Doubtful - loans which have all the weaknesses inherent in loans classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full highly questionable and improbable on the basis of currently known facts, conditions, and values.

Loss - loans which are considered by management to be uncollectible and of such little value that its continuance on the institution's books as an asset, without establishment of a specific valuation allowance or charge-off is not warranted.

\

In the following tables, retail loans are classified as Pass except when they reach 90 days past due or are downgraded to substandard, and upon reaching 120 days past due, they are downgraded to loss and charged off, in accordance with the FFIEC Uniform Retail Credit Classification and Account Management Policy. The risk grade classifications of retail loans secured by junior liens on 1-4 family residential properties also consider available information on the payment status of the associated senior lien with other financial institutions.

The average recorded investment in impaired loans was $952.3 million for the year ended December 31, 2013. Excluding accruing TDRs, there was no interest income recognized for the investment in impaired loans for the years ended December 31, 2015 , 2014, and 2013. Interest income recognized for accruing TDRs was $21.1 million for the year ended December 31, 2013. At December 31, 2015, 2014, and 2013, all impaired loans, other than $223.9 million, $348.4 million, and $556.4 million, respectively, of accruing TDRs, were on nonaccrual status.

Concessions provided in a TDR are primarily in the form of providing a below market interest rate given the borrower's credit risk, a period of time generally less than one year with a reduction of required principal and/or interest payments (e.g., interest only for a period of time), or extension of the maturity of the loan generally for less than one year. Insignificant periods of reduction of principal and/or interest payments, or one time deferrals of three months or less, are generally not considered to be financial concessions.

The following tables represent the post-modification balance, shown by type of concession, for loans modified or renewed during the years ended December 31, 2015 and 2014 that were reported as accruing or non-accruing TDRs.

If at the time that a loan was designated as a TDR the loan was not already impaired, the measurement of impairment resulting from the TDR designation changes from a general pool-level reserve to a specific loan measurement of impairment in accordance with ASC 310-10-35, Accounting By Creditors for Impairment of a Loan—an amendment of FASB Statements No. 5, ASC 450-20, and No. 15, ASC 310-40. Generally, the change in the allowance for loan losses resulting from such a TDR is not significant. At December 31, 2015, the allowance for loan losses allocated to accruing TDRs totaling $223.9 million was $12.6 million compared to accruing TDR's of $348.4 million with a related allowance for loan losses of $21.0 million at December 31, 2014. Nonaccrual non-homogeneous loans (commercial-type impaired loan relationships greater than $1 million) that are designated as TDRs are individually measured for the amount of impairment, if any, both before and after the TDR designation.

In the ordinary course of business, Synovus Bank has made loans to certain Synovus and Synovus Bank executive officers and directors (including their associates and affiliates). Management believes that such loans are made on the same terms, including interest rate and collateral, as those prevailing at the time for comparable transactions with unaffiliated customers.

The following is a summary of such loans and the activity in these loans for the year ended December 31, 2015.

In accordance with ASC 740-20-45-11(b), a deferred tax asset valuation allowance associated with unrealized gains and losses not recognized in income is charged directly to other comprehensive income (loss). During the years 2010 and 2011, Synovus recorded a deferred tax asset valuation allowance associated with unrealized gains and losses not recognized in income directly to other comprehensive income (loss) by applying the portfolio approach for allocation of the valuation allowance. Synovus has consistently applied the portfolio approach which treats derivative instruments, equity securities, and debt securities as a single portfolio. As of December 31, 2015, the ending balance in net unrealized gains (losses) on cash flow hedges and net unrealized gains (losses) on investment securities available for sale includes unrealized losses of $12.1 million and $13.3 million, respectively, related to the residual tax effects remaining in OCI due to the previously established deferred tax asset valuation allowance. Under the portfolio approach, these unrealized losses are realized at the time the entire portfolio is sold or disposed.

The following table illustrates activity within the reclassifications out of accumulated other comprehensive income (loss), for the years ended December 31, 2015, 2014, and 2013.

Repurchases of Common Stock

During the third quarter of 2015, Synovus completed its $250 million share repurchase program which was announced on October 21, 2014 and expired on October 23, 2015. Under this program, Synovus repurchased 9.1 million shares of common stock through a combination of share repurchases under the accelerated share repurchase (ASR) agreement described below and open market transactions. Synovus entered into an ASR agreement during October 2014 to purchase $75.0 million of Synovus common stock under the share repurchase program. During 2014, Synovus repurchased 2.5 million shares of common stock under the ASR agreement. During January 2015, Synovus repurchased 392 thousand shares upon completion of the ASR agreement. Additionally, from October 2014 through September 30, 2015, Synovus repurchased $175.0 million, or 6.2 million shares, of common stock through open market transactions, including $161.9 million, or 5.7 million shares, of common stock repurchased during 2015.

During the third quarter of 2015, Synovus' Board of Directors authorized a $300 million share repurchase program to be completed over the next 15 months. During the fourth quarter of 2015, under the new $300 million share repurchase program, Synovus repurchased $37.1 million, or 1.2 million shares. At December 31, 2015, the remaining authorization under this program is $262.9 million.

Reverse Stock Split and Increase in Number of Authorized Common Shares

On April 24, 2014, at Synovus' 2014 annual shareholders' meeting, Synovus’ shareholders approved a proposal authorizing Synovus’ Board of Directors to effect a one-for-seven reverse stock split of Synovus’ common stock. Following this annual meeting, Synovus’ Board of Directors authorized the one-for-seven reverse stock split. The reverse stock split became effective on May 16, 2014, and Synovus' shares of common stock began trading on a post-split basis on the NYSE at the opening of trading on May 19, 2014. All prior periods presented in this Report have been adjusted to reflect the one-for-seven reverse stock split. Financial information updated by this capital change includes earnings per common share, dividends per common share, stock price per common share, weighted average common shares, outstanding common shares, treasury shares, common stock, additional paid-in capital, and share-based compensation.

Regulatory Capital Disclosure [Abstract]

Regulatory Capital

Note 12 - Regulatory Capital

Synovus is subject to regulatory capital requirements administered by the federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, Synovus must meet specific capital levels that involve quantitative measures of both on- and off-balance sheet items as calculated under regulatory capital guidelines. Capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.

The Basel III capital rules, implemented in the U.S. with certain changes mandated by the Dodd-Frank Act, strengthen the definition of regulatory capital, increase risk-based capital requirements, and make selected changes to the calculation of risk-weighted assets. The rules became effective January 1, 2015, for Synovus and Synovus Bank, subject to a transition period for several aspects, including the capital conservation buffer and certain regulatory capital adjustments and deductions, as described below. Under the Basel III capital rules, the minimum capital requirements for Synovus and Synovus Bank include a common equity Tier 1 (CET1) ratio of 4.5%; Tier 1 capital ratio of 6%; total capital ratio of 8%; and leverage ratio of 4%. When fully phased-in on January 1, 2019, the Basel III capital rules include a capital conservation buffer of 2.5% that is added on top of each of the minimum risk-based capital ratios. The implementation of the capital conservation buffer will begin on January 1, 2016 at the 0.625% level and be phased-in over a three-year period (increasing by that amount on each subsequent January 1, until it reaches 2.5% on January 1, 2019). As a financial holding company, Synovus and its subsidiary bank, Synovus Bank, are required to maintain capital levels required for a well-capitalized institution as defined by federal banking regulations. Under the Basel III capital rules, Synovus and Synovus Bank are well-capitalized if each has a CET1 ratio of 6.5% or greater, a Tier 1 risk-based capital ratio of 8% or greater, a total risk-based capital ratio of 10% or greater, a leverage ratio of 5% or greater, and are not subject to any written agreement, order, capital directive, or prompt corrective action directive from a federal and/or state banking regulatory agency to meet and maintain a specific capital level for any capital measure.

Management currently believes, based on internal capital analyses and earnings projections, that Synovus' capital position is adequate to meet current and future regulatory minimum capital requirements.

The following table summarizes regulatory capital information at December 31, 2015 and 2014 on a consolidated basis and for Synovus’ significant subsidiary, defined as any direct subsidiary with assets or net income levels exceeding 10% of the consolidated totals.

Fair Value Accounting

Fair Value Disclosures [Abstract]

Fair Value Accounting

Note 14 - Fair Value Accounting

Synovus carries various assets and liabilities at fair value based on the fair value accounting guidance under ASC 820, Fair Value Measurements, and ASC 825, Financial Instruments. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an “exit price”) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

Synovus has implemented controls and processes for the determination of the fair value of financial instruments. The ultimate responsibility for the determination of fair value rests with Synovus. Synovus has established a process that has been designed to ensure there is an independent review and validation of fair values by a function independent of those entering into the transaction. This includes specific controls to ensure consistent pricing policies and procedures that incorporate verification for both market and derivative transactions. For all financial instruments where fair values are determined by reference to externally quoted prices or observable pricing inputs to models, independent price determination or validation is utilized. Where the market for a financial instrument is not active, fair value is determined using a valuation technique or pricing model. These valuation techniques and models involve a degree of estimation, the extent of which depends on each instrument's complexity and the availability of market-based data.

The most frequently applied pricing model and valuation technique utilized by Synovus is the discounted cash flow model. Discounted cash flows determine the value by estimating the expected future cash flows from assets or liabilities discounted to their present value. Synovus may also use a relative value model to determine the fair value of a financial instrument based on the market prices of similar assets or liabilities or an option pricing model such as binomial pricing that includes probability-based techniques. Assumptions and inputs used in valuation techniques and models include benchmark interest rates, credit spreads and other inputs used in estimating discount rates, bond and equity prices, price volatilities and correlations, prepayment rates, probability of default, and loss severity upon default.

Synovus refines and modifies its valuation techniques as markets develop and as pricing for individual financial instruments become more or less readily available. While Synovus believes its valuation techniques are appropriate and consistent with other market participants, the use of different methodologies or assumptions could result in different estimates of fair value at the balance sheet date. In order to determine the fair value, where appropriate, management applies valuation adjustments to the pricing information. These adjustments reflect management's assessment of factors that market participants would consider in setting a price, to the extent that these factors have not already been included in the pricing information. Furthermore, on an ongoing basis, management assesses the appropriateness of any model used. To the extent that the price provided by internal models does not represent the fair value of the financial instrument, management makes adjustments to the model valuation to calibrate it to other available pricing sources. Where unobservable inputs are used, management may determine a range of possible valuations based upon differing stress scenarios to determine the sensitivity associated with the valuation. As a final step, management considers the need for further adjustments to the modeled price to reflect how market participants would price the financial instrument.

Fair Value Hierarchy

Synovus determines the fair value of its financial instruments based on the fair value hierarchy established under ASC 820-10, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the financial instrument's fair value measurement in its entirety. There are three levels of inputs that may be used to measure fair value. The three levels of inputs of the valuation hierarchy are defined below:

Level 1	Quoted prices (unadjusted) in active markets for identical assets and liabilities for the instrument or security to be valued. Level 1 assets include marketable equity securities, Treasury securities, and mutual funds.
Level 2	Observable inputs other than Level 1 quoted prices, such as quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active or model-based valuation techniques for which all significant assumptions are derived principally from or corroborated by observable market data. Level 2 assets and liabilities include debt securities with quoted prices that are traded less frequently than exchange-traded instruments and derivative contracts whose value is determined by using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data. U.S. Government sponsored agency securities, mortgage-backed securities issued by GSEs and agencies, obligations of states and municipalities, collateralized mortgage obligations issued by GSEs, and mortgage loans held for sale are generally included in this category. Certain private equity investments that invest in publicly traded companies are also considered Level 2 assets.
Level 3	Unobservable inputs that are supported by little, if any, market activity for the asset or liability. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow models and similar techniques, and may also include the use of market prices of assets or liabilities that are not directly comparable to the subject asset or liability. These methods of valuation may result in a significant portion of the fair value being derived from unobservable assumptions that reflect Synovus' own estimates for assumptions that market participants would use in pricing the asset or liability. This category primarily consists of collateral-dependent impaired loans, other real estate, certain equity investments, and private equity investments.

Fair Value Option

Synovus has elected the fair value option for mortgage loans held for sale primarily to ease the operational burdens required to maintain hedge accounting for these loans. Synovus is still able to achieve effective economic hedges on mortgage loans held for sale without the time and expense needed to manage a hedge accounting program.

Valuation Methodology by Product

Following is a description of the valuation methodologies used for the major categories of financial assets and liabilities measured at fair value.

Trading Account Assets and Investment Securities Available for Sale

The fair values of trading securities and investment securities available for sale are primarily based on actively traded markets where prices are based on either quoted market prices or observed transactions. Management employs independent third-party pricing services to provide fair value estimates for Synovus' investment securities available for sale and trading securities. Fair values for fixed income investment securities are typically determined based upon quoted market prices, broker/dealer quotations for identical or similar securities, and/or inputs that are observable in the market, either directly or indirectly, for substantially similar securities. Level 1 securities are typically exchange quoted prices and include financial instruments such as U.S. Treasury securities, marketable equity securities, and mutual fund investments. Level 2 securities are typically matrix priced by the third-party pricing service to calculate the fair value. Such fair value measurements consider observable data such as relevant broker/dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayments speeds, credit information, and the respective terms and conditions for debt instruments. The types of securities classified as Level 2 within the valuation hierarchy primarily consist of collateralized mortgage obligations, mortgage-backed securities, debt securities of GSEs and agencies, corporate debt, and state and municipal securities.

When there is limited activity or less transparency around inputs to valuation, Synovus develops valuations based on assumptions that are not readily observable in the marketplace; these securities are classified as Level 3 within the valuation hierarchy. The majority of the balance of Level 3 investment securities available for sale consists primarily of trust preferred securities issued by financial institutions. Synovus also carries non-marketable common equity securities within this category. Synovus accounts for the non-marketable common equity securities in accordance with ASC 325-20, Investments-Other-Cost Method Investments, which requires these investments to be carried at cost. To determine the fair value of the trust preferred securities, management uses a measurement technique to reflect one that utilizes credit spreads and/or credit indices available from a third-party pricing service.  In addition, for each trust preferred security, management projects non-credit adjusted cash flows, and discounts those cash flows to net present value incorporating a relevant credit spread in the discount rate.  Other inputs to calculating fair value include potential discounts for lack of marketability.

Management uses various validation procedures to confirm the prices received from pricing services and quotations received from dealers are reasonable. Such validation procedures include reference to relevant broker/dealer quotes or other market quotes and a review of valuations and trade activity of comparable securities. Consideration is given to the nature of the quotes (e.g., indicative or firm) and the relationship of recently evidenced market activity to the prices provided by the third-party pricing service. Further, management also employs the services of an additional independent pricing firm as a means to verify and confirm the fair values of the primary independent pricing firms.

Mortgage Loans Held for Sale

Synovus elected to apply the fair value option for mortgage loans originated with the intent to sell to investors. When loans are not committed to an investor at a set price, fair value is derived from a hypothetical bulk sale model used to estimate the exit price of the loans in a loan sale. The bid pricing convention is used for loan pricing for similar assets. The valuation model is based upon forward settlements of a pool of loans of similar coupon, maturity, product, and credit attributes. The inputs to the model are continuously updated with available market and historical data. As the loans are sold in the secondary market and primarily used as collateral for securitizations, the valuation model represents the highest and best use of the loans in Synovus’ principal market. Mortgage loans held for sale are classified within Level 2 of the valuation hierarchy.

Private Equity Investments

Private equity investments consist primarily of equity method investments in venture capital funds, which are classified as Level 3 within the valuation hierarchy. The valuation of these investments requires significant judgment due to the absence of quoted market prices, inherent lack of liquidity, and the long-term nature of such investments. Based on these factors, the ultimate realizable value of these investments could differ significantly from the value reflected in the accompanying audited consolidated financial statements. For ownerships in publicly traded companies held in the funds, valuation is based on the closing market price at the balance sheet date, with such investments being classified as Level 1 or 2 within the valuation hierarchy. The valuation of marketable securities that have trading restrictions is discounted until the securities can be freely traded. The private equity investments in which Synovus holds a limited partnership interest consist of funds that invest in privately held companies. For privately held companies in the funds, the general partner estimates the fair value of the company in accordance with GAAP, as clarified by ASC 820, and guidance specific to investment companies. The estimated fair value of the company is the estimated fair value as an exit price the fund would receive if it were to sell the company in the marketplace. The fair value of the fund's underlying investments is estimated through the use of valuation models such as option pricing or a discounted cash flow model. Valuation factors, such as a company's operational performance against budget or milestones, last price paid by investors, with consideration given on whether financing is provided by insiders or unrelated new investors, public market comparables, liquidity of the market, industry and economic trends, and changes in management or key personnel, are used in the determination of fair value.

Also, Synovus holds an interest in an investment fund that invests in publicly traded financial services companies. Although the fund holds investments in publicly traded entities, the fair value of this investment is classified as Level 2 in the valuation hierarchy because there is no actively traded market for the fund itself, and the value of the investment is based on the aggregate fair value of the publicly traded companies that are held in the fund for investment.

Mutual Funds Held in Rabbi Trusts

Mutual funds held in rabbi trusts primarily invest in equity and fixed income securities. Shares of mutual funds are valued based on quoted market prices, and are therefore classified within Level 1 of the fair value hierarchy.

Salary Stock Units

Salary stock units represent fully vested stock awards that have been granted to certain key employees of Synovus. The salary stock units are classified as liabilities and are settled in cash, as determined by the average closing common stock price on the 20 trading days preceding the date of settlement and the number of salary stock units being settled. Accordingly, salary stock units are classified as Level 1 within the fair value hierarchy.

Derivative Assets and Liabilities

As part of its overall interest rate risk management activities, Synovus utilizes derivative instruments to manage its exposure to various types of interest rate risk. With the exception of one derivative contract discussed herein, Synovus' derivative financial instruments are all Level 2 financial instruments. The majority of derivatives entered into by Synovus are executed over-the-counter and consist of interest rate swaps. The fair values of these derivative instruments are determined based on an internally developed model that uses readily observable market data, as quoted market prices are not available for these instruments. The valuation models and inputs depend on the type of derivative and the nature of the underlying instrument, and include interest rates, prices and indices to generate continuous yield or pricing curves, volatility factors, and customer credit related adjustments. The principal techniques used to model the value of these instruments are an income approach, discounted cash flows, and Black-Scholes or binomial pricing models. The sale of TBA mortgage-backed securities for current month delivery or in the future and the purchase of option contracts of similar duration are derivatives utilized by Synovus, and are valued by obtaining prices directly from dealers in the form of quotes for identical securities or options using a bid pricing convention with a spread between bid and offer quotations. Interest rate swaps, floors, caps and collars, and TBA mortgage-backed securities are classified as Level 2 within the valuation hierarchy.

Synovus enters into interest rate lock commitments related to expected funding of residential mortgage loans at specified times in the future. Interest rate lock commitments that relate to the origination of mortgage loans that will be held-for-sale are considered derivative instruments under applicable accounting guidance. As such, Synovus records its interest rate lock commitments and forward loan sales commitments at fair value, determined as the amount that would be required to settle each of these derivative financial instruments at the balance sheet date. In the normal course of business, Synovus enters into contractual interest rate lock commitments to extend credit at a fixed interest rate and with fixed expiration dates. The commitments become effective when the borrowers "lock-in" a specified interest rate within the established time frames. Market risk arises if interest rates move adversely between the time of the interest rate lock by the borrower and the sale date of the loan to an investor. To mitigate the effect of the interest rate risk inherent in providing interest rate lock commitments to borrowers, Synovus enters into best efforts forward sales contracts with third-party investors. The forward sales contracts lock in a price for the sale of loans similar to the specific interest rate lock commitments. Both the interest rate lock commitments to the borrowers and the forward sales contracts to the investors are derivatives, and accordingly, are marked to fair value through earnings. In estimating the fair value of an interest rate lock commitment, Synovus assigns a probability to the interest rate lock commitment based on an expectation that it will be exercised and the loan will be funded. The fair value of the interest rate lock commitment is derived from the fair value of related mortgage loans, which is based on observable market data and includes the expected net future cash flows related to servicing of the loans. The fair value of the interest rate lock commitment is also derived from inputs that include guarantee fees negotiated with the agencies and private investors, buy-up and buy-down values provided by the agencies and private investors, and interest rate spreads for the difference between retail and wholesale mortgage rates. Management also applies fall-out ratio assumptions to the interest rate lock commitments in anticipation of those mortgage loans which will not close. The fall-out ratio assumptions are based on Synovus' historical experience, conversion ratios for similar loan commitments, and market conditions. While fall-out tendencies are not exact predictions of which loans will or will not close, historical performance review of loan-level data provides the basis for determining the appropriate hedge ratios. In addition, on a periodic basis, Synovus performs analyses of actual rate lock fall-out experience to determine the sensitivity of the mortgage pipeline to interest rate changes from the date of the commitment through loan origination. The expected fall-out ratios (or conversely the "pull-through" percentages) are applied to the determined fair value of the mortgage pipeline. Changes to the fair value of interest rate lock commitments are recognized based on interest rate changes, changes in the probability that the commitment will be exercised, and the passage of time. The fair value of the forward sales contracts to investors considers the market price movement of the same type of security between the trade date and the balance sheet date. These instruments are classified as Level 2 within the valuation hierarchy.

In November 2009, Synovus sold certain Visa Class B shares to another Visa USA member financial institution. The sales price was based on the Visa stock conversion ratio in effect at the time for conversion of Visa Class B shares to Visa Class A unrestricted shares at a future date. In conjunction with the sale, Synovus entered into a derivative contract with the purchaser (the Visa derivative), which provides for settlements between the parties based upon a change in the ratio for conversion of Visa Class B shares to Visa Class A shares. The fair value of the Visa derivative is determined based on management's estimate of the timing and amount of the Covered Litigation settlement and the resulting payments due to the counterparty under the terms of the contract. Since this estimation process requires application of judgment in developing significant unobservable inputs used to determine the fair value of the Visa derivative, this derivative has been classified as Level 3 within the valuation hierarchy. See "Part II - Item 8. Financial Statements and Supplementary Data - Note 17 - Visa Shares and Related Agreements" of this Report for additional discussion on the Visa derivative and related litigation.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The following table presents all financial instruments measured at fair value on a recurring basis as of December 31, 2015 and 2014, according to the valuation hierarchy included in ASC 820-10. For equity and debt securities, class was determined based on the nature and risks of the investments. Transfers between levels for the years ended December 31, 2015 and 2014 were inconsequential.

^{(1 )} Based on an analysis of the nature and risks of these investments, Synovus has determined that presenting these investments as a single asset class is appropriate.

^{(2 )} Mortgage derivatives consist of customer interest rate lock commitments that relate to the potential origination of mortgage loans, which would be classified as held for sale and forward loan sales commitments with third-party investors.

Fair Value Option

The following table summarizes the difference between the fair value and the unpaid principal balance of mortgage loans held for sale measured at fair value and the changes in fair value of these loans. Mortgage loans held for sale are initially measured at fair value with subsequent changes in fair value recognized in earnings. Changes in fair value were recorded as a component of mortgage banking income in the consolidated statements of income. An immaterial portion of these changes in fair value was attributable to changes in instrument-specific credit risk.

Changes in Level 3 Fair Value Measurements

As noted above, Synovus uses significant unobservable inputs (Level 3) in determining the fair value of assets and liabilities classified as Level 3 in the fair value hierarchy. The table below includes a roll-forward of the amounts on the consolidated balance sheet for the year ended December 31, 2015 and 2014 (including the change in fair value), for financial instruments of a material nature that are classified by Synovus within Level 3 of the fair value hierarchy and are measured at fair value on a recurring basis. Transfers between fair value levels are recognized at the end of the reporting period in which the associated changes in inputs occur. During 2015 and 2014, Synovus did not have any transfers between levels in the fair value hierarchy.

Assets Measured at Fair Value on a Non-recurring Basis

Certain assets are recorded at fair value on a non-recurring basis. These non-recurring fair value adjustments typically are a result of the application of lower of cost or fair value accounting or a write-down occurring during the period. For example, if the fair value of an asset in these categories falls below its cost basis, it is considered to be at fair value at the end of the period of the adjustment. The following table presents assets measured at fair value on a non-recurring basis as of the dates indicated for which there was a fair value adjustment during the period.

	As of December 31, 2015					Fair Value Adjustments for the Year Ended December 31, 2015

* Impaired loans that are collateral-dependent.

Collateral-dependent impaired loans are evaluated for impairment in accordance with the provisions of ASC 310-10-35 using the fair value of the collateral less costs to sell. For loans measured using the estimated fair value of collateral securing these loans less costs to sell, fair value is generally determined based upon appraisals performed by a certified or licensed appraiser using inputs such as absorption rates, capitalization rates, and market comparables, adjusted for estimated selling costs. Management also considers other factors or recent developments, such as changes in absorption rates or market conditions from the time of valuation, and anticipated sales values considering management's plans for disposition, which could result in adjustments to the collateral value estimates indicated in the appraisals. Estimated costs to sell are based on actual amounts for similar assets. These measurements are classified as Level 3 within the valuation hierarchy. Collateral-dependent impaired loans are reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly based on the same factors identified above.

Loans are transferred to other loans held for sale at fair value when Synovus makes the determination to sell specifically identified loans. The fair value of the loans is primarily determined by analyzing the underlying collateral of the loan and the anticipated market prices of similar assets less estimated costs to sell, as well as consideration of the market for loan sales versus the sale of collateral. At the time of transfer, if the estimated fair value is less than the carrying amount, the difference is recorded as a charge-off against the allowance for loan losses. Decreases in the fair value subsequent to the transfer, as well as gains/losses realized from the sale of these assets, are recorded as losses on other loans held for sale, net, as a component of non-interest expense on the consolidated statements of income.

ORE consists of properties obtained through a foreclosure proceeding or through an in-substance foreclosure in satisfaction of loans. The fair value of ORE is determined on the basis of current appraisals, comparable sales, and other estimates of fair value obtained principally from independent sources, adjusted for estimated selling costs. At foreclosure, ORE is recorded at the lower of cost or fair value less the estimated cost to sell, which establishes a new cost basis. Subsequent to foreclosure, ORE is evaluated quarterly and reported at fair value less estimated costs to sell, not to exceed the new cost basis, determined on the basis of current appraisals, comparable sales, and other estimates of fair value obtained principally from independent sources, adjusted for estimated selling costs. In the determination of fair value subsequent to foreclosure, management also considers other factors or recent developments, such as changes in absorption rates or market conditions from the time of valuation, and anticipated sales values considering management’s plans for disposition, which could result in an adjustment to lower the fair value estimates indicated in the appraisals. Internally adjusted valuations are considered Level 3 measurements as management uses assumptions that may not be observable in the market.

Other assets held for sale consist of certain premises and equipment held for sale, including those related to the efficiency initiatives discussed in "Note 3 - Restructuring Charges" of this Report. These assets are classified as held for sale and recorded at the lower of their amortized cost or fair value, less costs to sell, consistent with ASC 360-10, Impairment and Disposal of Long-Lived Assets. The fair value of these assets is determined primarily on the basis of appraisals or BOV, as circumstances warrant, adjusted for estimated selling costs. Both techniques engage licensed or certified professionals that use inputs such as absorption rates, capitalization rates, and market comparables; these valuations are considered Level 3 measurements since assumptions or inputs may not be observable in the market.

Quantitative Information about Level 3 Fair Value Measurements

The tables below provide an overview of the valuation techniques and significant unobservable inputs used in those techniques to measure financial instruments that are classified within Level 3 of the valuation hierarchy. The range of sensitivities that management utilized in its fair value calculations is deemed acceptable in the industry with respect to the identified financial instruments. The tables below present both the total balance as of the dates indicated for assets measured at fair value on a recurring basis and the assets measured at fair value on a non-recurring basis for which there was a fair value adjustment during the period.

⁽¹⁾ The range represents management's best estimate of the high and low end of the value that would be assigned to a particular input. For assets measured at fair value on a non-recurring basis, the weighted average is the measure of central tendencies; it is not the value that management is using for the asset or liability.

⁽²⁾ Represents management's estimate of discount that market participants would require based on the instrument's lack of liquidity.

Sensitivity Analysis of Level 3 Unobservable Inputs Measured on a Recurring Basis

Included in the fair value estimates of financial instruments carried at fair value on the consolidated balance sheet are those estimated in full or in part using valuation techniques based on assumptions that are not supported by observable market prices, rates, or other inputs. Unobservable inputs are assessed carefully, considering the current economic environment and market conditions. However, by their very nature, unobservable inputs imply a degree of uncertainty in their determination, because they are supported by little, if any, market activity for the related asset or liability.

Investment Securities Available for Sale

The significant unobservable inputs used in the fair value measurement of the corporate obligations in Level 3 assets are the credit spread embedded in the discount rate and the discount for lack of liquidity. Generally, a change in one or more assumptions, and the degree or sensitivity of the change used, can have a significant impact on fair value. With regard to the trust preferred securities in Level 3 assets, raising the credit spread, and raising the discount for lack of liquidity assumptions will result in a lower fair value measurement.

Private Equity Investments

In the absence of quoted market prices, inherent lack of liquidity, and the long-term nature of private equity investments, significant judgment is required to value these investments. The significant unobservable inputs used in the fair value measurement of private equity investments include current operations, financial condition and cash flows, comparables and private sales, when available, and recently executed financing transactions related to investee companies. Significant increases or decreases in any of these inputs in isolation would result in a significantly lower or higher fair value measurement.

Visa Derivative Liability

The fair value of the Visa derivative is determined based on management's estimate of the timing and amount of the Covered Litigation settlement and the resulting payments due to the counterparty under the terms of the contract. Significant changes in any of these inputs could result in a significantly higher (lower) valuation of the Visa derivative liability. Also, additional funding into the escrow generally results in a proportional increase in our derivative liability.

Fair Value of Financial Instruments

The following table presents the carrying and fair values of financial instruments at December 31, 2015 and 2014. The fair values represent management’s best estimates based on a range of methodologies and assumptions. For financial instruments that are not recorded at fair value on the balance sheet, such as loans, interest bearing deposits (including brokered deposits), and long-term debt, the fair value amounts should not be taken as an estimate of the amount that would be realized if all such financial instruments were to be settled immediately.

Cash and cash equivalents, interest bearing funds with the Federal Reserve Bank, interest earning deposits with banks, and federal funds sold and securities purchased under resale agreements are repriced on a short-term basis; as such, the carrying value closely approximates fair value. Since these amounts generally relate to highly liquid assets, these are considered a Level 1 measurement.

Loans, net of deferred fees and costs, are recorded at the amount of funds advanced, less charge-offs, and an estimation of credit risk represented by the allowance for loan losses. The fair value estimates for disclosure purposes differentiate loans based on their financial characteristics, such as product classification, loan category, pricing features, and remaining maturity. The fair value of loans is estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type, such as commercial, mortgage, home equity, credit card, and other retail loans. Commercial loans are further segmented into certain collateral code groupings. The fair value of the loan portfolio is calculated, in accordance with ASC 825-10, by discounting contractual cash flows using estimated market discount rates, which reflect the credit and interest rate risk inherent in the loan. This method of estimating fair value does not incorporate the exit-price concept of fair value prescribed by ASC 820-10 and generally produces a higher value than the exit price approach. For loans measured using the estimated fair value of collateral less costs to sell, fair value is generally estimated using appraisals of the collateral. Collateral values are monitored and additional write-downs are recognized if it is determined that the estimated collateral values have declined further. Estimated costs to sell are based on current disposal costs for similar assets. Carrying value is considered to reflect fair value for these loans. Loans are considered a Level 3 fair value measurement.

The fair value of deposits with no stated maturity, such as non-interest bearing demand accounts, interest bearing demand deposits, money market accounts, and savings accounts, is estimated to be equal to the amount payable on demand as of that respective date. The fair value of time deposits is based on the discounted value of contractual cash flows. The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities. The value of long-term relationships with depositors is not taken into account in estimating fair values. Synovus has developed long-term relationships with its customers through its deposit base and, in the opinion of management, these customer relationships add significant value to Synovus. Synovus has determined that the appropriate classification for deposits is Level 2 due to the ability to reasonably measure all inputs to valuation based on observable market variables. Short-term and long-term debt is also considered a Level 2 valuation, as management relies on market prices for bonds or debt that is similar, but not necessarily identical, to the debt being valued. Short-term debt that matures within ten days is assumed to be at fair value, and is considered a Level 1 measurement. The fair value of other short-term and long-term debt with fixed interest rates is calculated by discounting contractual cash flows using market discount rates for bonds or debt that is similar but not identical.

The carrying and estimated fair values of financial instruments, as well as the level within the fair value hierarchy, as of December 31, 2015 and 2014 are as follows:

Summary of Derivative Instruments [Abstract]

Derivative Instruments

Note 15 - Derivative Instruments

As part of its overall interest rate risk management activities, Synovus utilizes derivative instruments to manage its exposure to various types of interest rate risk. These derivative instruments generally consist of interest rate swaps, interest rate lock commitments made to prospective mortgage loan customers, and commitments to sell fixed-rate mortgage loans. Interest rate lock commitments represent derivative instruments since it is intended that such loans will be sold.

Synovus may also utilize interest rate swaps to manage interest rate risks primarily arising from its core banking activities. These interest rate swap transactions generally involve the exchange of fixed and floating interest rate payment obligations without the exchange of underlying principal amounts. Swaps may be designated as either cash flow hedges or fair value hedges, as discussed below. As of December 31, 2015 and 2014, Synovus had no outstanding interest rate swap contracts utilized to manage interest rate risk.

Synovus is party to master netting arrangements with its dealer counterparties; however, Synovus does not offset assets and liabilities under these arrangements for financial statement presentation purposes.

Counterparty Credit Risk and Collateral

Entering into derivative contracts potentially exposes Synovus to the risk of counterparties’ failure to fulfill their legal obligations, including, but not limited to, potential amounts due or payable under each derivative contract. Notional principal amounts are often used to express the volume of these transactions, but the amounts potentially subject to credit risk are much smaller. Synovus assesses the credit risk of its dealer counterparties by regularly monitoring publicly available credit rating information, evaluating other market indicators, and periodic detailed financial reviews. Dealer collateral requirements are determined via risk-based policies and procedures and in accordance with existing agreements. Synovus seeks to minimize dealer credit risk by dealing with highly rated counterparties and by obtaining collateral for exposures above certain predetermined limits. Management closely monitors credit conditions within the customer swap portfolio, which management deems to be of higher risk than dealer counterparties. Collateral is secured at origination and credit related fair value adjustments are recorded against the asset value of the derivative as deemed necessary based upon an analysis, which includes consideration of the current asset value of the swap, customer credit rating, collateral value, and customer standing with regards to its swap contractual obligations and other related matters. Such asset values fluctuate based upon changes in interest rates regardless of changes in notional amounts and changes in customer specific risk.

Cash Flow Hedges

Synovus designates hedges of floating rate loans as cash flow hedges. These swaps hedge against the variability of cash flows from specified pools of floating rate prime based loans. Synovus calculates effectiveness of the hedging relationship quarterly using regression analysis. The effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transactions affect earnings. Ineffectiveness from cash flow hedges is recognized in the consolidated statements of income as a component of other non-interest income. As of December 31, 2015, there were no cash flow hedges outstanding, and therefore, no cumulative ineffectiveness.

Synovus expects to reclassify from accumulated other comprehensive income (loss) $196 thousand to loss on early extinguishment of debt and $271 thousand to interest expense during the next twelve months as amortization of deferred losses is recorded.

Synovus did not terminate any cash flow hedges during 2015 or 2014. The remaining unamortized deferred loss balance of all previously terminated cash flow hedges at December 31, 2015 and 2014 was $(597) thousand and $(1.1) million, respectively.

Fair Value Hedges

Synovus designates hedges of fixed rate liabilities as fair value hedges. These swaps hedge against the change in fair value of various fixed rate liabilities due to changes in the benchmark interest rate, LIBOR. Synovus calculates effectiveness of the fair value hedges quarterly using regression analysis. Ineffectiveness from fair value hedges is recognized in the consolidated statements of income as a component of other non-interest income. As of December 31, 2015, there were no fair value hedges outstanding, and therefore, no cumulative ineffectiveness.

Synovus did not terminate any fair value hedges during 2015 or 2014. The remaining unamortized deferred gain balance on all previously terminated fair value hedges at December 31, 2015 and 2014 was $4.0 million and $7.6 million, respectively. Synovus expects to reclassify from hedge-related basis adjustment, a component of long-term debt, $1.8 million of the deferred gain balance on previously terminated fair value hedges as a reduction to interest expense during the next twelve months as amortization of deferred gains is recorded. Additionally, Synovus will record $1.3 million of the deferred gain balance to loss on early extinguishment of debt during the first quarter of 2016.

Customer Related Derivative Positions

Synovus enters into interest rate swap agreements to facilitate the risk management strategies of a small number of commercial banking customers. Synovus mitigates this risk by entering into equal and offsetting interest rate swap agreements with highly rated counterparties. The interest rate swap agreements are free-standing derivatives and are recorded at fair value on Synovus' consolidated balance sheet. Fair value changes are recorded in non-interest income in Synovus' consolidated statements of income. As of December 31, 2015, the notional amount of customer related interest rate derivative financial instruments, including both the customer position and the offsetting position, was $1.28 billion, an increase of $184.8 million compared to December 31, 2014.

Visa Derivative

In conjunction with the sale of Class B shares of common stock issued by Visa to Synovus as a Visa USA member, Synovus entered into a derivative contract with the purchaser, which provides for settlements between the parties based upon a change in the ratio for conversion of Visa Class B shares to Visa Class A shares. The conversion ratio changes when Visa deposits funds to a litigation escrow established by Visa to pay settlements for certain litigation, for which Visa is indemnified by Visa USA members. The litigation escrow is funded by proceeds from Visa’s conversion of Class B shares. The fair value of the derivative contract was $1.4 million at December 31, 2015 and 2014. The fair value of the derivative contract is determined based on management's estimate of the timing and amount of the Covered Litigation settlement, and the resulting payments due to the counterpary under the terms of the contract. See "Part II - Item 8. Financial Statements and Supplementary Data - Note 17 - Visa Shares and Related Agreements" of this Report for further information.

Mortgage Derivatives

Synovus originates first lien residential mortgage loans for sale into the secondary market. Mortgage loans are sold by Synovus for conversion to securities and the servicing of these loans is generally sold to a third-party servicing aggregator, or Synovus sells the mortgage loans as whole loans to investors either individually or in bulk on a servicing released basis.

Synovus enters interest rate lock commitments for residential mortgage loans which commits it to lend funds to a potential borrower at a specific interest rate and within a specified period of time. Interest rate lock commitments that relate to the origination of mortgage loans that, if originated, will be held for sale, are considered derivative financial instruments under applicable accounting guidance. Outstanding interest rate lock commitments expose Synovus to the risk that the price of the mortgage loans underlying the commitments may decline due to increases in mortgage interest rates from inception of the rate lock to the funding of the loan.

At December 31, 2015 and 2014, Synovus had commitments to fund at a locked interest rate, primarily fixed-rate mortgage loans to customers in the amount of $88.8 million and $73.4 million, respectively. The fair value of these commitments resulted in a gain of $175 thousand and $606 thousand for the year ended December 31, 2015 and 2014, respectively, which was recorded as a component of mortgage banking income in the consolidated statements of income.

At December 31, 2015 and 2014, outstanding commitments to sell primarily fixed-rate mortgage loans amounted to $95.0 million and $113.0 million, respectively. Such commitments are entered into to reduce the exposure to market risk arising from potential changes in interest rates, which could affect the fair value of mortgage loans held for sale and outstanding rate lock commitments, which guarantee a certain interest rate if the loan is ultimately funded or granted by Synovus as a mortgage loan held for sale. The commitments to sell mortgage loans are at fixed prices and are scheduled to settle at specified dates that generally do not exceed 90 days. The fair value of outstanding commitments to sell mortgage loans resulted in a gain of $924 thousand and a loss of $(1.7) million for the years ended December 31, 2015 and 2014, respectively, which was recorded as a component of mortgage banking income in the consolidated statements of income.

Collateral Contingencies

Certain derivative instruments contain provisions that require Synovus to maintain an investment grade credit rating from each of the major credit rating agencies. If Synovus’ credit rating falls below investment grade, these provisions allow the counterparties of the derivative instrument to demand immediate and ongoing full collateralization on derivative instruments in net liability positions and, for certain counterparties, request immediate termination. Additionally, certain counterparties require full collateralization on derivative instruments in a net liability position. Also, as of June 10, 2013, the CCC became mandatory for certain trades as required under the Dodd-Frank Act. These derivative transactions also carry collateral requirements, both at the inception of the trade, and as the value of each derivative position changes. As trades are migrated to the CCC, dealer counterparty exposure will be reduced, and higher notional amounts of Synovus' derivative instruments will be housed at the CCC, a highly regulated and well-capitalized entity. As of December 31, 2015, collateral totaling $65.9 million of Federal funds sold was pledged to the derivative counterparties, including $13.7 million with the CCC, to comply with collateral requirements.

The impact of derivative instruments on the consolidated balance sheets at December 31, 2015 and 2014 is presented below.

During the years ended December 31, 2015, 2014, and 2013, Synovus reclassified $3.1 million, $3.1 million, and $3.2 million, respectively, from hedge-related basis adjustment, a component of long-term debt, as a reduction to interest expense. Additionally, during 2015, Synovus reclassified $495 thousand from hedge-related basis adjustment, as a reduction to loss on early extinguishment of debt. These deferred gains relate to hedging relationships that have been previously terminated and are reclassified into earnings over the remaining life of the hedged items.

Variable Interest Entities

Variable Interest Entities [Abstract]

Variable Interest Entities

Note 16 - Variable Interest Entities

Synovus has a contractual ownership or other interests in certain VIEs for which the fair value of the VIE's net assets may change exclusive of the variable interests. Under ASC 810, Consolidation, Synovus is deemed to be the primary beneficiary and required to consolidate a VIE if it has a variable interest in the VIE that provides it with a controlling financial interest. For such purposes, the determination of whether a controlling financial interest exists is based on whether a single party has both the power to direct the activities of the VIE that most significantly impact the VIE's economic performance and the obligation to absorb the losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. ASC 810-10-65, as amended, requires continual reconsideration of conclusions reached regarding which interest holder is a VIE's primary beneficiary.

Synovus’ involvement with VIEs is discussed below. Synovus consolidates VIEs for which it is deemed the primary beneficiary.

Consolidated Variable Interest Entities

Rabbi Trusts – Synovus has established certain rabbi trusts related to deferred compensation plans offered to its employees. Synovus contributes employee cash compensation deferrals to the trusts and directs the underlying investments made by the trusts. The assets of these trusts are available to Synovus creditors only in the event that Synovus becomes insolvent. These trusts are considered VIEs because either there is no equity at risk in the trusts or because Synovus provided the equity interest to its employees in exchange for services rendered. While the employees have the ability to direct their funds within the trusts, Synovus is considered the primary beneficiary of the rabbi trusts as it has the ability to direct the underlying investments made by the trusts as well as make funding decisions related to the trusts, the activities that most significantly impact the economic performance of the rabbi trusts. Synovus includes the assets of the rabbi trusts as a component of other assets and a corresponding liability for the associated benefit obligation in other liabilities in its consolidated balance sheets. At December 31, 2015 and 2014, the aggregate amount of rabbi trust assets and benefit obligation was $10.7 million and $11.3 million, respectively.

Non-consolidated Variable Interest Entities

Low Income Housing Tax Credit Partnerships – Synovus and its subsidiary bank, Synovus Bank, make equity investments as a limited partner in various partnerships which are engaged in the development and operation of affordable multi-family housing utilizing the LIHTC pursuant to Section 42 of the Internal Revenue Code. The purpose of these investments is to earn a return on the investment and to support community reinvestment initiatives of Synovus’ subsidiary bank. The activities of these LIHTC partnerships are limited to development and operation of multi-family housing that is leased to qualifying residential tenants. These partnerships are generally located in southeastern communities where Synovus has a banking presence and are considered VIEs because Synovus, as the holder of an equity investment at risk, does not have voting or similar rights and does not participate in the management or direct the operations of the partnerships (activities which affect the success of the partnerships). Synovus provides construction lending for certain of the LIHTC partnerships in which it also has an equity investment. Synovus is at risk for the amount of its equity investment plus the outstanding amount of any construction loans in excess of the fair value of the collateral for the loan but has no obligation to fund the operations or working capital of the partnerships. The general partners of these partnerships are considered the primary beneficiaries because they are charged with management responsibility which give them the power to direct the activities that most significantly impact the financial performance of the partnerships, and they are exposed to losses beyond Synovus’ equity investment. At December 31, 2015 and 2014, the aggregate carrying value of Synovus’ investments in LIHTC partnerships was $18.9 million and $10.9 million, respectively, and the cumulative amount of equity investments was $29.3 million in 2015 and $29.1 million in 2014. Synovus uses the equity method of accounting for these investments which are included as a component of other assets on Synovus’ consolidated balance sheet. At December 31, 2015 and 2014, Synovus had $12.2 million and $3.6 million, respectively, commitments to fund equity investments in LIHTC partnerships.

Certain Commercial Loans – For certain troubled commercial loans, Synovus restructures the terms of the borrower’s debt in an effort to increase the probability of receipt of amounts contractually due. A troubled debt restructuring generally requires consideration of whether the borrowing entity is a VIE as economic events may have proven that the entity’s equity is not sufficient to permit it to finance its activities without additional subordinated financial support or a restructuring of the terms of its financing. As Synovus does not have the power to direct the activities that most significantly impact such troubled commercial borrowers’ operations, it is not considered the primary beneficiary, even in situations where, based on the size of the financing provided, Synovus is exposed to potentially significant benefits and losses of the borrowing entity. Synovus has no contractual requirements to provide financial support to the borrowing entities beyond certain funding commitments established upon restructuring of the terms of the debt that allow for preparation of the underlying collateral for sale.

Visa Shares and Litigation Expense [Abstract]

Visa Shares and Litigation Expense

Note 17 - Visa Shares and Related Agreements

Synovus is a member of the Visa USA network and received shares of Visa Class B common stock in exchange for its membership interest in Visa USA in conjunction with the Visa IPO in 2008. Visa members have indemnification obligations with respect to the Covered Litigation. Visa Class B shares are subject to certain restrictions until settlement of the Covered Litigation. As of December 31, 2015, all of the Covered Litigation had not been settled. Visa has established a litigation escrow to fund settlement of the Covered Litigation. The litigation escrow is funded by proceeds from Visa's conversion of Class B shares to Class A shares.

In November 2009, Synovus sold its remaining Visa Class B shares to another Visa USA member financial institution. In conjunction with the sale, Synovus entered into a derivative contract with the purchaser which provides for settlements between the parties based upon a change in the ratio for conversion of Visa Class B shares to Visa Class A shares. As of December 31, 2015 and 2014, the fair value of the derivative contract was $1.4 million. The fair value of the derivative contract is determined based on management's estimate of the timing and amount of the Covered Litigation settlement, and the resulting payments due to the counterparty under the terms of the contract. For the years ended December 31, 2015, 2014 and 2013, Synovus recognized indemnification charges of $1.5 million, $3.0 million and $1.6 million, respectively.

Management believes that the estimate of Synovus' exposure to the Visa indemnification and fees associated with the Visa derivative is adequate based on current information, including Visa's recent announcements and disclosures. However, future developments in the litigation could require potentially significant changes to Synovus' estimate.

Commitments and Contingencies

Note 18 - Commitments and Contingencies

In the normal course of business, Synovus enters into commitments to extend credit such as loan commitments and letters of credit to meet the financing needs of its customers. Synovus uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee.

The contractual amount of these financial instruments represents Synovus' maximum credit risk should the counterparty draw upon the commitment, and should the counterparty subsequently fail to perform according to the terms of the contract. Since many of the commitments are expected to expire without being drawn upon, total commitment amounts do not necessarily represent future cash requirements.

The carrying amount of loan commitments and letters of credit closely approximates the fair value of such financial instruments. Carrying amounts include unamortized fee income and, in some instances, allowances for any estimated credit losses from these financial instruments. These amounts are not material to Synovus' consolidated balance sheets.

Unfunded lending commitments and letters of credit at December 31, 2015 are presented below.

(in thousands)
Letters of credit*	$	166,936
Commitments to fund commercial real estate, construction, and land development loans	1,882,130
Unused credit card lines	1,055,181
Commitments under home equity lines of credit	1,051,386
Commitments to fund commercial and industrial loans	4,094,809

* Represents the contractual amount net of risk participations of $66 million.

Lease Commitments

Synovus and its subsidiaries have entered into long-term operating leases for various facilities and equipment. Management expects that as these leases expire they will be renewed or replaced by similar leases based on need.

At December 31, 2015, minimum rental commitments under all such non-cancelable leases for the next five years and thereafter are presented below.

Rental expense on facilities was $26.6 million, $25.9 million, and $25.6 million for the years ended December 31, 2015, 2014, and 2013, respectively.

Repurchase Obligations for Mortgage Loans Originated for Sale

The majority of mortgage loans originated by Synovus are sold to third-party purchasers on a servicing released basis, without recourse, or continuing involvement (Synovus does not retain the servicing rights). These loans are originated and underwritten internally by Synovus personnel and are primarily to borrowers in Synovus’ geographic market footprint. These sales are typically effected as non-recourse loan sales to GSEs and non-GSE purchasers.

Each GSE and non-GSE purchaser has specific guidelines and criteria for sellers of loans, and the risk of credit loss with regard to the principal amount of the loans sold is generally transferred to the purchasers upon sale. The purchase agreements require Synovus to make certain representations and warranties regarding the existence and sufficiency of file documentation and the absence of fraud by borrowers or other third parties such as appraisers in connection with obtaining the loan. If it is determined that loans sold were in breach of these representations or warranties, Synovus has obligations to either repurchase the loan at the unpaid principal balance and related investor fees or make the purchaser whole for the economic benefits of the loan.

To date, repurchase activity pursuant to the terms of these representations and warranties has been minimal and has primarily been associated with loans originated from 2005 through 2008. From January 1, 2005 through December 31, 2015, Synovus Mortgage originated and sold approximately $8.9 billion of first lien GSE eligible mortgage loans and approximately $3.9 billion of first and second lien non-GSE eligible mortgage loans. The total expense pertaining to losses from repurchases of mortgage loans previously sold, including amounts accrued in accordance with ASC 450, was $920 thousand, $2.0 million, and $1.7 million for the years ended December 31, 2015, 2014, and 2013, respectively. The total accrued liability related to mortgage repurchase claims was $3.2 million at both December 31, 2015 and

Legal Proceedings

Note 19 - Legal Proceedings

Synovus and its subsidiaries are subject to various legal proceedings and claims that arise in the ordinary course of its business. Additionally, in the ordinary course of business, Synovus and its subsidiaries are subject to regulatory examinations, information gathering requests, inquiries and investigations. Synovus, like many other financial institutions, has been the target of numerous legal actions and other proceedings asserting claims for damages and related relief for losses. These actions include claims and counterclaims asserted by individual borrowers related to their loans and allegations of violations of state and federal laws and regulations relating to banking practices, including putative class action matters. In addition to actual damages if Synovus does not prevail in any asserted legal action, credit-related litigation could result in additional write-downs or charge-offs of assets, which could adversely affect Synovus' results of operations during the period in which the write-down or charge-off were to occur.

Synovus carefully examines and considers each legal matter, and, in those situations where Synovus determines that a particular legal matter presents loss contingencies that are both probable and reasonably estimable, Synovus establishes an appropriate accrual. An event is considered to be probable if the future event is likely to occur. While the final outcome of any legal proceeding is inherently uncertain, based on the information currently available, advice of counsel and available insurance coverage, management believes that the amounts accrued with respect to legal matters as of December 31, 2015 are adequate. The actual costs of resolving legal claims may be higher or lower than the amounts accrued.

In addition, where Synovus determines that there is a reasonable possibility of a loss in respect of legal matters, including those legal matters described below, Synovus considers whether it is able to estimate the total reasonably possible loss or range of loss. An event is “reasonably possible” if “the chance of the future event or events occurring is more than remote but less than likely.” An event is “remote” if “the chance of the event or future event occurring is more than slight but less than reasonably possible." In many situations, Synovus may be unable to estimate reasonably possible losses due to the preliminary nature of the legal matters, as well as a variety of other factors and uncertainties. For those legal matters where Synovus is able to estimate a range of reasonably possible losses, management currently estimates the aggregate range from our outstanding litigation, including, without limitation, the matters described below, is from zero to $15 million in excess of the amounts accrued, if any, related to those matters. This estimated aggregate range is based upon information currently available to Synovus, and the actual losses could prove to be higher. As there are further developments in these legal matters, Synovus will reassess these matters, and the estimated range of reasonably possible losses may change as a result of this assessment. Based on Synovus' current knowledge and advice of counsel, management presently does not believe that the liabilities arising from these legal matters will have a material adverse effect on Synovus' consolidated financial condition, results of operations or cash flows. However, it is possible that the ultimate resolution of these legal matters could have a material adverse effect on Synovus' results of operations for any particular period.

Synovus intends to vigorously pursue all available defenses to these legal matters, but will also consider other alternatives, including settlement, in situations where there is an opportunity to resolve such legal matters on terms that Synovus considers to be favorable, including in light of the continued expense and distraction of defending such legal matters. Synovus also maintains insurance coverage, which may (or may not) be available to cover legal fees, or potential losses that might be incurred in connection with the legal matters described below. The above-noted estimated range of reasonably possible losses does not take into consideration insurance coverage which may or may not be available for the respective legal matters.

Posting Order Litigation

On September 21, 2010, Synovus, Synovus Bank and CB&T were named as defendants in a putative multi-state class action relating to the manner in which Synovus Bank charges overdraft fees to customers. The case, Childs et al. v. Columbus Bank and Trust et al., was filed in the Northern District of Georgia, Atlanta Division, and asserted claims for breach of contract and breach of the covenant of good faith and fair dealing, unconscionability, conversion and unjust enrichment for alleged injuries suffered by plaintiffs as a result of Synovus Bank's assessment of overdraft charges in connection with its POS/debit and automated-teller machine cards transactions allegedly resulting from the sequence used to post payments to the plaintiffs' accounts. On October 25, 2010, the Childs case was transferred to a multi-district proceeding in the Southern District of Florida. On August 23, 2014, Synovus reached a settlement in principle with plaintiffs' counsel to settle the Posting Order Litigation. Under the settlement in principle, Synovus agreed to pay $3.75 million plus payment of $150,000 in settlement expenses (the "Posting Order Settlement Payment") in exchange for broad releases, dismissal with prejudice of the Posting Order Litigation and other material and customary terms and conditions. The District Court granted final approval of the Posting Order Settlement Payment on April 2, 2015.

TelexFree Litigation

On October 22, 2014, several pending lawsuits were consolidated into a multi-district putative class action case captioned In re: TelexFree Securities Litigation, MDL Number 4:14-md2566-TSH, United States District Court District of Massachusetts. Synovus and Synovus Bank were named as defendants with numerous other defendants in the purported class action lawsuit.  An Amended Complaint was filed on March 31, 2015 which consolidated and amended the claims previously asserted. The claims against Synovus were dismissed by Plaintiffs on April 10, 2015 so now, as to Synovus-related entities, only claims against Synovus Bank remain pending.  TelexFree was a merchant customer of Base Commerce, LLC, an independent sales organization/member service provider sponsored by Synovus Bank. The purported class action lawsuit generally alleges that TelexFree engaged in an improper multi-tier marketing scheme involving voice-over Internet protocol telephone services and that the various defendants, including Synovus Bank, provided financial services to TelexFree that allowed TelexFree to conduct its business operations. Synovus Bank filed a motion to dismiss the lawsuit on June 1, 2015, which remains pending before the Court.

Synovus Bank believes it has substantial defenses related to these purported claims and intends to vigorously defend the claims asserted. Synovus currently cannot reasonably estimate losses attributable to this matter.

Share-based Compensation [Abstract]

Share-Based Compensation

Note 21 - Share-based Compensation

General Description of Share-based Plans

Synovus has a long-term incentive plan under which the Compensation Committee of the Board of Directors has the authority to grant share-based awards to Synovus employees. The 2013 Omnibus Plan authorizes 8,571,429 common share equivalents available for grant, where grants of options count as one share equivalent and grants of full value awards (e.g., restricted share units, market restricted share units, and performance share units) count as two share equivalents. Any restricted share units that are forfeited and options that expire unexercised will again become available for issuance under the Plan. At December 31, 2015, Synovus had a total of 7,050,823 shares of its authorized but unissued common stock reserved for future grants under the 2013 Omnibus Plan. The Plan permits grants of share-based compensation including stock options, restricted share units, market restricted share units, and performance share units. The grants generally include vesting periods ranging from three to five years and contractual terms of ten years. Stock options are granted at exercise prices which equal the fair market value of a share of common stock on the grant date. As further discussed below, market restricted share units and performance share units are granted at target and are compared annually to required market and performance metrics. Synovus has historically issued new shares to satisfy share option exercises and share unit conversions. Dividend equivalents are paid on outstanding restricted share units, market restricted share units, and performance share units in the form of additional restricted share units that vest over the same vesting period or the vesting period left on the original restricted share unit grant.

During 2015, Synovus awarded 321,874 restricted share units to employees and non-employee directors that contained a service-based vesting period of three years. During 2015, Synovus also granted 82,152 market restricted share units and 82,152 performance share units to senior management. The weighted average grant-date fair value of the awarded restricted share units, market restricted share units, and performance share units was $28.09, $29.39, and $28.06 per share, respectively. During 2014, Synovus awarded 407,374 restricted share units to employees and non-employee directors that contained a service-based vesting period of three years. During 2014, Synovus also granted 90,117 market restricted share units and 67,157 performance share units to senior management. The weighted average grant-date fair value of the awarded restricted share units, market restricted share units, and performance share units was $23.69, $24.30, and $23.47 per share, respectively. During 2013, Synovus granted 212,660 restricted share units and 40,512 market restricted share units with a weighted average grant-date fair value of $19.60 and $24.43, respectively. The restricted share units and the market restricted share units granted during 2015, 2014, and 2013 contain a service-based vesting period of three years with most awards vesting pro-rata over three years. During 2013, Synovus also granted 857,607 stock options with a weighted average exercise price of $17.64 and service-based vesting pro-rata over three years.

Share-based Compensation Expense

Total share-based compensation expense was $12.6 million, $10.2 million, and $7.5 million for 2015, 2014, and 2013, respectively. The total income tax benefit recognized in the consolidated statements of income for share-based compensation arrangements was approximately $4.6 million, $3.9 million, and $2.9 million for 2015, 2014, and 2013, respectively. No share-based compensation costs have been capitalized for the years ended December 31, 2015, 2014, and 2013.

As of December 31, 2015, unrecognized compensation cost related to the unvested portion of share-based compensation arrangements involving shares of Synovus stock was approximately $15.2 million.

Stock Options

The fair value of stock option grants used in measuring compensation expense was determined using the Black-Scholes option pricing model with the following weighted-average assumptions for grants made in 2013. There were no stock option grants in 2015 or 2014.

	2013
Risk-free interest rate	1.11	%
Expected stock price volatility	50.0
Dividend yield	1.6
Expected life of options	6.0 years

The stock price expected volatility for awards granted in 2013 was based on Synovus' historical and implied volatility. The expected life for stock options granted during 2013 was calculated using the “simplified” method as prescribed by SAB No. 110. The weighted average grant-date fair value of stock options granted in 2013 was $7.21.

A summary of stock option activity and changes during the years ended December 31, 2015, 2014, and 2013 is presented below.

Stock Options

Options exercisable at end of year	1,504,783		$	41.08	1,870,516		$	55.40	1,999,195		$	68.74

The aggregate intrinsic value for outstanding stock options at December 31, 2015 was $19.3 million and the aggregate intrinsic value for options exercisable at December 31, 2015 was $15.8 million. As of December 31, 2015, the weighted average remaining contractual life was 4.90 years for options outstanding and 4.54 years for options exercisable.

The intrinsic value of stock options exercised during the years ended December 31, 2015, 2014, and 2013 was $4.4 million, $1.3 million, and $367 thousand, respectively. Cash received from option exercises of common stock for the years ended December 31, 2015, 2014, and 2013 was $5.6 million, $3.0 million, and $1.0 million, respectively. The total grant date fair value of stock options vested during 2015, 2014, and 2013 was $6.5 million, $4.9 million, and $4.3 million, respectively. At December 31, 2015, total unrecognized compensation cost related to non-vested stock options was approximately $249 thousand. This cost is expected to be recognized during the first quarter of 2016.

Restricted Share Units, Market Restricted Share Units, and Performance Share Units

Compensation expense is measured based on the grant date fair value of restricted share units, market restricted share units, and performance share units. The fair value of restricted share units and performance share units is equal to the market price of common stock on the grant date. The fair value of market restricted share units granted was estimated on the date of grant using a Monte Carlo simulation model with the following weighted average assumptions:

	2015		2014		2013
Risk-free interest rate	1.05	%	0.70	%	0.63	%
Expected stock price volatility	26.4		39.2		40.0
Dividend yield	1.4		1.2		1.2
Simulation period	3.0 years		3.0 years		3.0 years

The stock price expected volatility was based on Synovus' historical and implied volatility. The Monte Carlo model estimates fair value based on 100,000 simulations of future share price using a theoretical model of stock price behavior.

The weighted-average grant-date fair value of restricted share units granted during 2015 was $28.09 and the weighted-average grant date fair value of market restricted share units granted during 2015 was $29.39. The grant date fair value of performance share units granted during 2015 was $28.06. The weighted-average grant-date fair value of restricted share units granted during 2014 was $23.69 and the weighted-average grant date fair value of market restricted share units granted during 2014 was $24.30. The grant date fair value of performance share units granted during 2014 was $23.47. The weighted-average grant-date fair value of restricted share units granted during 2013 was $19.60 and the grant date fair value of the market restricted share units granted during 2013 was $24.43. The total fair value of restricted share units vested during 2015, 2014, and 2013 was $12.3 million, $1.6 million, and $11.6 million, respectively. The total fair value of restricted share units vested during 2013 of $11.6 million included $7.4 million from restricted share units that vested upon redemption of Synovus' Series A Preferred Stock on July 26, 2013. Cash paid for taxes due on vesting of employee restricted share units where restricted share units were withheld to cover taxes was $5.1 million, $692 thousand, and $3.6 million for the years ended December 31, 2015, 2014, and 2013, respectively.

A summary of restricted share units outstanding and changes during the years ended December 31, 2015, 2014, and 2013 is presented below (excluding market restricted and performance share units).

As of December 31, 2015, total unrecognized compensation cost related to the foregoing restricted share units was approximately $9.9 million. This cost is expected to be recognized over a weighted-average remaining period of 1.41years.

Synovus granted 82,152 market restricted share units to senior management during the year ended December 31, 2015 with a grant date fair value of $29.39. During 2014 and 2013, Synovus granted market restricted share units to senior management totaling 90,117 and 40,512, respectively, with a grant date fair value of $24.30 and $24.43, respectively. The market restricted share units have a three-year service-based vesting component as well as a total shareholder return multiplier. The number of market restricted share units that will ultimately vest ranges from 75% to 125% of target based on Synovus' total shareholder return (TSR). The total fair value of market restricted share units vested during 2015 and 2014 was $1.4 million and $398 thousand, respectively. At December 31, 2015, total unrecognized compensation cost related to market restricted share units was approximately $2.8 million with a weighted average remaining period of 1.36 years. A summary of market restricted share units outstanding and changes during the years ended December 31, 2015, 2014, and 2013 is presented below.

During the year ended December 31, 2015, Synovus granted 82,152 performance share units to senior management. These units have a grant date fair value of $28.06 and vest upon meeting certain service and performance conditions. During the year ended December 31, 2014, Synovus granted 67,157 performance share units with a grant date fair value of $23.47 to senior management. Return on average assets (ROAA) performance is evaluated each year over a three-year performance period, with share distribution determined at the end of the three years. The number of performance share units that will ultimately vest ranges from 0% to 150% of target based on Synovus' three-year weighted average ROAA (as defined). At December 31, 2015, total unrecognized compensation cost related to performance share units was approximately $2.2 million with a weighted average remaining period of 1.42 years. A summary of performance share units outstanding and changes during the years ended December 31, 2015 and 2014 is presented below.

Salary Stock Units and Other Information

During 2014 and 2013, Synovus also granted 44,527 and 70,015, respectively, salary stock units to senior management, which vested and were expensed immediately upon grant. Compensation expense was initially determined based on the number of salary stock units granted and the market price of common stock at the grant date. Subsequent to the grant date, compensation expense was recorded for changes in common stock market price. The total fair value of salary stock units granted during 2014 and 2013 was $1.2 million and $1.8 million, respectively. The salary stock units granted during 2014 were classified as liabilities and were settled in cash on January 15, 2015.

During 2015, Synovus recognized a share-based compensation net tax benefit of $1.7 million associated with vesting of restricted share units, stock option exercises, and expired stock options which was recorded as a component of additional paid-in capital within shareholders' equity. During 2014, Synovus recognized a net tax deficiency of $3.2 million associated primarily with expired stock options. The deficiency was recorded as a reduction of additional paid-in capital within shareholders' equity. During 2013, Synovus recognized a net tax benefit of $317 thousand. Synovus' future stock price will determine if a tax benefit is realized on outstanding stock options.

Note: The table above does not reflect amounts relating to share-based compensation transactions that were charged or credited directly to shareholders' equity. The amounts charged or credited to shareholder's equity for the years ended December 31, 2015, 2014, and 2013 were an increase of $1.7 million, a decrease of $3.2 million, and an increase of $317 thousand, respectively.

Income tax expense does not reflect the tax effects of unrealized gains (losses) on investment securities available for sale and unamortized actuarial gains on post-retirement unfunded health benefits. This information is presented in the consolidated statements of comprehensive income.

Income tax expense as shown in the consolidated statements of income differed from the amounts computed by applying the U.S. federal income tax rate of 35 percent to income before income taxes. A reconciliation of the differences for the years ended December 31, 2015, 2014 and 2013 is shown below:

	Years Ended December 31,

The net decrease in the valuation allowance for the years ended December 31, 2015 and 2014 was $589 thousand and $2.3 million, respectively. The net decrease in the valuation allowance for the years ended December 31, 2015 and 2014 was due to expiring unused state credits.

Management assesses the realizability of deferred tax assets at each reporting period. The determination of whether a valuation allowance for deferred tax assets is appropriate is subject to considerable judgment and requires an evaluation of all the positive and negative evidence. At December 31, 2015, the Company is not in a three-year cumulative loss position; accordingly, it does not have significant negative evidence to consider when evaluating the realization of its deferred tax assets. Positive evidence supporting the realization of the Company’s deferred tax assets at December 31, 2015 includes generation of taxable income in 2015, 2014, and 2013, continued improvement in credit quality, record of long-term positive earnings prior to the most recent economic downturn, the Company’s strong capital position, as well as sufficient amounts of projected future taxable income, of the appropriate character, to support the realization of $511.9 million of the Company’s net deferred tax asset at December 31, 2015. The Company expects to realize its net deferred tax asset of $511.9 million at December 31, 2015 through the reversal of existing taxable temporary differences and projected future taxable income. The valuation allowance of $11.7 million at December 31, 2015 relates to specific state income tax credits that have various expiration dates through the tax year 2019, and are expected to expire before they can be realized. Based on the assessment of all the positive and negative evidence at December 2015 and 2014, management has concluded that it is more likely than not that the results of future operations will generate sufficient taxable income to realize the deferred tax assets.

Synovus expects to realize substantially all of the $511.9 million in net deferred tax assets well in advance of the statutory carryforward period. At December 31, 2015, $155.6 million of existing deferred tax assets are not related to net operating losses or credits and therefore, have no expiration dates. $256.8 million of the remaining deferred tax assets relate to federal net operating losses which expire in years beginning in 2030 through 2032. Additionally, $51.8 million of the deferred tax assets relate to state net operating losses which will expire in installments annually through the tax year 2035. Tax credit carryforwards at December 31, 2015 include federal alternative minimum tax credits totaling $31.7 million which have an unlimited carryforward period. Other federal and state tax credits at December 31, 2015 total $27.7 million and have expiration dates through the tax year 2035.

Federal and state NOL and tax credit carryforwards as of December 31, 2015 are summarized in the following table.

Tax Carryforwards	As of December 31, 2015

Synovus is subject to income taxation in the United States and various state jurisdictions. Synovus' federal income tax return is filed on a consolidated basis, while state income tax returns are filed on both a consolidated and separate entity basis. Currently, there are no years for which Synovus filed a federal income tax return that are under examination by the IRS; however, a state tax examination from the Department of Revenue for Louisiana is currently in progress. Synovus is no longer subject to income tax examinations by the IRS for years before 2011, and excluding certain limited exceptions, Synovus is no longer subject to income tax examinations by state and local income tax authorities for years before 2011. However, amounts reported as net operating losses and tax credit carryovers from closed tax periods remain subject to review by most taxing authorities. Although Synovus is unable to determine the ultimate outcome of current and future examinations, Synovus believes that the liability recorded for uncertain tax positions is adequate.

A reconciliation of the beginning and ending amount of unrecognized income tax benefits is as follows (unrecognized state income tax benefits are not adjusted for the federal income tax impact).

	Years Ended December 31,

Settlements	—			—
Balance at December 31,	$	12,745		13,023

* Includes deferred tax benefits that could reduce future tax liabilities.

Accrued interest and penalties related to unrecognized income tax benefits are included as a component of income tax expense. Accrued interest and penalties on unrecognized income tax benefits totaled $105 thousand and $96 thousand as of January 1 and December 31, 2015, respectively. Unrecognized income tax benefits as of January 1 and December 31, 2015 that, if recognized, would affect the effective income tax rate totaled $8.5 million and $8.3 million (net of the federal benefit on state income tax issues), respectively, which includes interest and penalties of $68 thousand and $63 thousand, respectively. Synovus expects that $320 thousand of uncertain income tax positions will be either settled or resolved during the next twelve months.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2015

Accounting Policies [Abstract]

Cash and Cash Equivalents

Cash and cash equivalents consist of cash and due from banks. At December 31, 2015 and 2014, $100 thousand and $125 thousand, respectively, of the due from banks balance was restricted as to withdrawal.

Short-term Investment

Short-term investments consist of interest bearing funds with the Federal Reserve Bank, interest earning deposits with banks, and Federal funds sold and securities purchased under resale agreements. At December 31, 2015 and 2014, interest bearing funds with the Federal Reserve Bank included$117.3 million and $89.2 million, respectively, on deposit to meet Federal Reserve Bank reserve requirements. Interest earning deposits with banks include $2.2 million at December 31, 2015 and $7.1 million at December 31, 2014, which is pledged as collateral in connection with certain letters of credit. Federal funds sold include $65.9 million at December 31, 2015 and $67.5 million at December 31, 2014, which are pledged to collateralize certain derivative instruments. Federal funds sold and securities purchased under resale agreements, and Federal funds purchased and securities sold under repurchase agreements, generally mature in one day.

Trading Account Assets

Trading account assets, which are primarily held on a short-term basis for the purpose of selling at a profit, consist of debt and equity securities and are reported at fair value. Fair value adjustments and fees from trading account activities are included as a component of other fee income on the consolidated statements of income. Gains and losses realized from the sale of trading account assets are determined by specific identification and are included as a component of other fee income on the trade date. Interest income on trading assets is reported as a component of interest income on the consolidated statements of income.

Mortgage Loans Held for Sale and Mortgage Banking Income

Mortgage Loans Held for Sale

Mortgage loans held for sale are recorded at fair value. Fair value is derived from a hypothetical bulk sale model used to estimate the exit price of the loan in a loan sale. The bid pricing convention is used for loan pricing for similar assets. The valuation model is based upon forward settlements of a pool of loans of similar coupon, maturity, product, and credit attributes. The inputs to the model are continuously updated with available market and historical data. As the loans are sold in the secondary market, the valuation model produces an estimate of fair value that represents the highest and best use of the loans in Synovus' principal market.

Mortgage Banking Income

Mortgage banking income consists primarily of origination and ancillary fees on loans originated for sale, and gains and losses from the sale of mortgage loans. Mortgage loans are generally sold servicing released, without recourse or continuing involvement, and meet ASC 860-10-65, Transfers and Servicing of Financial Assets, criteria for sale accounting.

Other Loans Held for Sale

Loans are transferred to other loans held for sale at fair value when Synovus makes the determination to sell specifically identified loans. The fair value of the loans is primarily determined by analyzing the underlying collateral of the loan and the anticipated market prices of similar assets less estimated costs to sell. At the time of transfer, if the estimated fair value is less than the carrying amount, the difference is recorded as a charge-off against the allowance for loan losses. Decreases in the fair value subsequent to the transfer, as well as gains/losses realized from the sale of these assets, are recorded as losses on other loans held for sale, net, as a component of non-interest expense on the consolidated statements of income.

Investment Securities Available for Sale

Investment securities available for sale are carried at fair value with unrealized gains and losses, net of the related tax effect, excluded from earnings and reported as a separate component of shareholders' equity within accumulated other comprehensive income (loss) until realized.

Synovus performs a quarterly assessment of its investment securities available for sale to determine if the decline in fair value of a security below its amortized cost is deemed to be other-than-temporary. Factors included in the assessment include the length of time the security has been in a loss position, the extent that the fair value is below amortized cost, and the credit standing of the issuer. Other-than-temporary impairment losses are recognized on securities when: (1) the holder has an intention to sell the security; (2) it is more likely than not that the security will be required to be sold prior to recovery; or (3) the holder does not expect to recover the entire amortized cost basis of the security. Other-than-temporary impairment losses are reflected in earnings as realized losses to the extent the impairment is related to credit losses. The amount of the impairment related to other factors is recognized in other comprehensive income (loss).

Premiums and discounts are amortized or accreted over the life of the related security as an adjustment to yield using the effective interest method and prepayment assumptions. Actual prepayment experience is reviewed periodically and the timing of the accretion and amortization is adjusted accordingly. Interest income on securities available for sale is recorded on the accrual basis. Realized gains and losses for securities are included in investment securities gains (losses), net, on the consolidated statements of income and are derived using the specific identification method, on a trade date basis.

Loans and Interest Income on Loans

Loans are reported at principal amounts outstanding less amounts charged off, net of deferred fees and expenses. Interest income and deferred fees, net of expenses on loans, are recognized on a level yield basis.

Non-accrual Loans

Loans on which the accrual of interest has been discontinued are designated as non-accrual loans. Accrual of interest is discontinued on loans when reasonable doubt exists as to the full collection of interest or principal, or when loans become contractually past due for 90 days or more as to either interest or principal, in accordance with the terms of the loan agreement, unless they are both well-secured and in the process of collection. When a loan is placed on non-accrual status, previously accrued and uncollected interest is generally reversed as an adjustment to interest income on loans. Interest payments received on non-accrual loans are generally recorded as a reduction of principal. As payments are received on non-accruing loans, interest income can be recognized on a cash basis; however, there must be an expectation of full repayment of the remaining recorded principal balance. The remaining portion of this payment is recorded as a reduction to principal. Loans are generally returned to accruing status when they are brought fully current with respect to interest and principal and when, in the judgment of management, the loans are estimated to be fully collectible as to both principal and interest, and the borrower has sustained repayment performance under the terms of the loan agreement for a reasonable period of time (generally six months).

Impaired Loans

Impaired loans are loans for which it is probable that Synovus will not be able to collect all amounts due according to the contractual terms of the loan agreements and all loans modified in a troubled debt restructuring (TDR). Other than TDRs, impaired loans do not include smaller-balance homogeneous loans that are collectively evaluated for impairment, which consist of most retail loans and commercial loan relationships less than $1.0 million. Impairment is measured on a discounted cash flow method based upon the loan's contractual effective interest rate, or at the loan's observable market price, or at the fair value of the collateral, less costs to sell if the loan is collateral-dependent. Interest income on non-accrual impaired loans is recognized as described above under "non-accrual loans." Impaired accruing loans generally consist of those troubled debt restructurings for which management has concluded that the collectability of the loan is not in doubt.

At December 31, 2015, substantially all non-accrual impaired loans were collateral-dependent and secured by real estate. For impairment measured using the estimated fair value of collateral less costs to sell, fair value is estimated using appraisals performed by a certified or licensed appraiser. Management also considers other factors or recent developments, such as selling costs and anticipated sales values, taking into account management's plans for disposition, which could result in adjustments to the fair value estimates indicated in the appraisals. The assumptions used in determining the amount of the impairment are subject to significant judgment. Use of different assumptions, for example, changes in the fair value of the collateral or management's plans for disposition could have a significant impact on the amount of impairment.

Under the discounted cash flow method, impairment is recorded as a specific reserve with a charge-off for any portion of the impairment considered a confirmed loss. The reserve is reassessed each quarter and adjusted as appropriate based on changes in estimated cash flows.

Where guarantors are determined to be a source of repayment, an assessment of the guarantee is required. This guarantee assessment would include, but not be limited to, factors such as type and feature of the guarantee, consideration for the guarantor's financial strength and capacity to service the loan in combination with the guarantor's other financial obligations as well as the guarantor's willingness to assist in servicing the loan.

Troubled Debt Restructurings

When borrowers are experiencing financial difficulties, Synovus may, in order to assist the borrowers in repaying the principal and interest owed to Synovus, make certain modifications to the borrower's loan. All loan modifications and renewals are evaluated for troubled debt restructuring (TDR) classification. In accordance with ASU 2011-02, A Creditor's Determination of Whether a Restructuring is a Troubled Debt Restructuring, a TDR is defined as a modification with a borrower that is experiencing financial difficulties, and the creditor has granted a financial concession that it would not normally make. The market interest rate concept in ASU 2011-02 states that if a borrower does not otherwise have access to funds at a market interest rate for debt with characteristics similar to those of the restructured debt, the restructuring would be considered to be at a below-market rate, which indicates that the lender may have granted a concession. Since Synovus often increases or maintains the interest rate upon renewal of a commercial loan, including renewals of loans involving borrowers experiencing financial difficulties, the market rate concept has become a significant factor in determining if a loan is classified as a TDR. All TDRs are considered to be impaired loans, and the amount of impairment, if any, is determined in accordance with ASC 310-10-35, Accounting by Creditors for Impairment of a Loan-an amendment of FASB Statements No. 5, ASC 450-20, and No. 15, ASC 310-40.

Concessions provided by Synovus in a TDR are generally made in order to assist borrowers so that debt service is not interrupted and to mitigate the potential for loan losses. A number of factors are reviewed when a loan is renewed, refinanced, or modified, including cash flows, collateral values, guarantees, and loan structures. Concessions are primarily in the form of providing a below market interest rate given the borrower's credit risk to assist the borrower in managing cash flows, an extension of the maturity of the loan generally for less than one year, or a period of time generally less than one year with a reduction of required principal and/or interest payments (e.g., interest only for a period of time). These types of concessions may be made during the term of a loan or upon the maturity of a loan, as a loan renewal. Renewals of loans made to borrowers experiencing financial difficulties are evaluated for TDR designation by determining if concessions are being granted, including consideration of whether the renewed loan has an interest rate that is at market, given the credit risk related to the loan. Insignificant periods of reduction of principal and/or interest payments, or one time deferrals of three months or less, are generally not considered to be financial concessions. Further, it is generally Synovus' practice not to defer principal and/or interest for more than twelve months.

These types of concessions may be made during the term of a loan or upon the maturity of a loan, in which the borrower is experiencing financial difficulty, as a loan renewal.

Renewals of loans made to borrowers experiencing financial difficulties are evaluated for TDR designation by determining if concession(s) are being granted, including consideration of whether the renewed loan has an interest rate that is at market, given the credit risk related to the loan.

Non-accruing TDRs may generally be returned to accrual status if there has been a period of performance, usually at least a six month sustained period of repayment performance by the borrower. Consistent with regulatory guidance, a TDR will generally no longer be reported as a TDR after a period of performance and after the loan was reported as a TDR at a year-end reporting date, and if at the time of the modification, the interest rate was at market, considering the credit risk associated with the borrower.

Allowance for Loan Losses

The allowance for loan losses is a significant accounting estimate that is determined through periodic and systematic detailed reviews of the Company’s loan portfolio. These reviews are performed to assess the probable incurred losses within the portfolio and to ensure consistency between fluctuations in the allowance and both credit events within the portfolio and prevailing credit trends. The economic and business climate in any given industry or market is difficult to gauge and can change rapidly, and the effects of those changes can vary by borrower. Significant judgments and estimates are necessary in the determination of the allowance for loan losses. Significant judgments include, among others, loan risk ratings and classifications, the determination and measurement of impaired loans, the timing of loan charge-offs, the probability of loan defaults, the net loss exposure in the event of loan defaults, the loss emergence period, qualitative loss factors, management’s plans, if any, for disposition of certain loans, as well as other qualitative considerations. In determining the allowance for loan losses, management makes numerous assumptions, estimates, and assessments, which are inherently subjective. The use of different estimates or assumptions could have a significant impact on the provision for loan losses, allowance for loan losses, non-performing loans, loan charge-offs and the Company's consolidated financial condition and results of operations.

The allocated allowance is based upon quarterly analyses of impaired commercial loans to determine the amount of specific reserves (and/or loan charge-offs), if any, as well as an analysis of historical loan default experience, loan net loss experience, loss emergence experience, and related qualitative factors, if appropriate, for categories of loans with similar risk attributes and further segregated by Synovus' internal loan grading system.

Impaired loans are generally evaluated on a loan by loan basis with specific reserves, if any, recorded as appropriate. Specific reserves are determined based on ASC 310-10-35, which provides for measurement of a loan's impairment based on one of three methods. If the loan is collateral-dependent, then the fair value of the loan's collateral, less estimated selling costs, are compared to the loan's carrying amount to determine impairment. Other methods of measuring a loan's impairment include the present value of the expected future cash flows of the loan, or if available, the observable market price of the loan. Synovus considers the pertinent facts and circumstances for each impaired loan when selecting the appropriate method to measure impairment, and quarterly evaluates each selection to ensure its continued appropriateness and evaluates the reasonableness of specific reserves, if any.

For loans that are not considered impaired, the allocated allowance for loan losses is determined based upon Expected Loss (EL) factors, which are applied to groupings of specific loan types by loan risk ratings. The EL is determined based upon a probability of default (PD), which is the probability that a borrower, segregated by loan type and loan risk grade, will default, and loss given default (LGD), which is the estimate of the amount of net loss in the event of default. The groupings of the loans into loan categories are determined based upon the nature of the loan types and the level of inherent risk associated with the various loan categories. The loan groupings are further segregated based upon the individual loan risk ratings, as described below. The EL factors applied in the methodology are periodically re-evaluated and adjusted to reflect changes in historical loss levels or other risks.

Allocated EL factors may also be adjusted, as necessary, for certain qualitative factors that in management's judgment are necessary to reflect losses incurred in the portfolio.

Qualitative factors that management considers in the analysis include:

• changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses

• changes in the volume and severity of past due loans, the volume of non-accrual loans, and the volume and severity of adversely classified or grade loans

• loan growth

• effects of changes in credit concentrations

• experience, ability, and depth of lending management, loan review personnel, and other relevant staff

• changes in the quality of the loan review function

• national and local economic trends and conditions

• value of underlying collateral for collateral-dependent loans

• other external factors such as the effects for the current competitive, legal, and regulatory environment

The adjusted EL factors by portfolio are then adjusted by a loss emergence period for each loan type. A loss emergence period represents the amount of time between when a loss event first occurs to when it is charged off. The loss emergence period was determined for each loan type based on the Company's historical experience and is validated annually.

Commercial Loans - Risk Ratings

Synovus utilizes two primary methods for risk assessment of the commercial loan portfolio: Single Risk Rating Assessment and Dual Risk Rating (DRR) Assessment. The single and dual risk ratings are based on the borrowers' credit risk profile, considering factors such as debt service history, current and estimated prospective cash flow information, collateral supporting the credit, source of repayment as well as other variables, as appropriate.

Each loan is assigned a risk rating during its initial approval process. For single risk rated loans, this process begins with a loan rating recommendation from the loan officer responsible for originating the loan. Commercial single risk rated loans are graded on a 9-point scale. Single risk ratings six through nine are defined consistent with the bank regulatory classifications of special mention, substandard, doubtful, and loss, respectively. The primary determinants of the risk ratings for commercial single risk rated loans are the reliability of the primary source of repayment and the borrower's expected performance (i.e., the likelihood that the borrower will be able to service its obligations in accordance with the terms). Expected performance will be based upon full analysis of the borrower's historical financial results, current financial strength and future prospects, which includes any external drivers.

For dual risk rated loans, this process begins with scoring the loan for a rating during its initial approval process. Synovus began utilizing a dual risk rating methodology for certain components of its commercial and industrial loan portfolio in 2013 and extended the DRR methodology to certain income-producing real estate loans in 2014 and 2015. The DRR includes sixteen probabilities of default categories and nine categories for estimating losses given an event of default. The result is an expected loss rate established for each borrower.

The loan rating is subject to approvals from other members of management, regional credit and/or loan committees depending on the size of the loan and loan's credit attributes. Loan ratings are regularly re-evaluated based upon annual scheduled credit reviews or on a more frequent basis if determined prudent by management.Additionally, an independent loan review function evaluates Synovus' risk rating processes on a continuous basis.

Management currently expects to implement the DRR methodology for additional components of the commercial loan portfolio over the next few years. The implementation is expected to be in multiple phases, with each component determined based primarily on loan type and size. The timing of future implementations will depend upon completion of applicable data analysis and model assessment. Once full implementation is completed, management estimates that the DRR methodology will be utilized to calculate the allowance for loan losses on commercial loans amounting to approximately 35% of the total loan portfolio. Approximately $6.7 billion, or 29.8%, of the total loan portfolio was rated using the DRR methodology at year-end 2015.

Retail Loans – Risk Ratings

Retail loans are generally assigned a risk rating on a 6-point scale at the time of origination based on credit bureau scores, with a loan grade of 1 assigned as the lowest level of risk and a loan grade of 6 as the highest level of risk. At 90-119 days past due, a loan grade of 7-substandard rating is applied and at 120 days past due, the loan is generally downgraded to grade 9-loss and is generally charged-off. The credit bureau-based ratings are updated at least semi-annually and the ratings based on the past due status are updated monthly.

Unallocated Allowance for Loan Losses

The unallocated component of the allowance for loan losses is not a significant component of the ALLL, but would be utilized to provide for certain environmental and economic factors that affect the inherent risk of loss in the entire loan portfolio that are not fully captured in the allocated allowance for loan losses. On a quarterly basis, management updates its analysis and consideration of these factors and determines the impact, if any, on the allowance for loan losses and the provision for loan losses for each respective period.

Premises and Equipment

Premises and equipment, including bank owned branch locations and leasehold improvements, are reported at cost, less accumulated depreciation and amortization, which are computed using the straight-line method over the estimated useful lives of the related assets. Leasehold improvements are depreciated over the shorter of the estimated useful life or the remainder of the lease term. Synovus reviews long-lived assets, such as premises and equipment, for impairment whenever events and circumstances indicate that the carrying amount of an asset may not be recoverable.

Goodwill

Goodwill represents the excess purchase price over the fair value of identifiable net assets of acquired businesses. In accordance with ASC 350, Intangibles, Goodwill and Other, goodwill is not amortized, but tested for impairment at the reporting unit (sub-segment) level on an annual basis and as events occur or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Synovus reviews goodwill for impairment as of June 30^th and at interim periods if indicators of impairment exist.

Significant judgment is applied when goodwill is assessed for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, incorporating general economic and market conditions, and selecting an appropriate control premium. The selection and weighting of the various fair value techniques may result in a higher or lower fair value. Judgment is applied in determining the weighting that are most representative of fair value.

Other Real Estate

Other Real Estate (ORE) consists of properties obtained through a foreclosure proceeding or through an in-substance foreclosure in satisfaction of loans. In accordance with the provisions of ASC 310-10-35 regarding subsequent measurement of loans for impairment and ASC 310-40-15 regarding accounting for troubled debt restructurings by a creditor, a loan is classified as an in-substance foreclosure when Synovus has taken possession of the collateral regardless of whether formal foreclosure proceedings have taken place.

At foreclosure, ORE is recorded at the lower of cost or fair value less estimated selling costs, which establishes a new cost basis. Subsequent to foreclosure, ORE is evaluated quarterly and reported at fair value less estimated selling costs, not to exceed the new cost basis, determined by review of current appraisals, as well as the review of comparable sales and other estimates of fair value obtained principally from independent sources, adjusted for estimated selling costs. Management also considers other factors or recent developments such as changes in absorption rates or market conditions from the time of the latest appraisal received or previous re-evaluation performed, and anticipated sales values considering management's plans for disposition, which could result in an adjustment to lower the fair value estimates indicated in the appraisals. At the time of foreclosure or initial possession of collateral, any excess of the loan balance over the fair value of the real estate held as collateral, less costs to sell, is recorded as a charge against the allowance for loan losses. Revenue and expenses from ORE operations as well as gains or losses on sales are recorded as foreclosed real estate expense, net, a component of non-interest expense on the consolidated statements of income. Subsequent declines in fair value are recorded on a property-by-property basis through use of a valuation allowance within other real estate on the consolidated balance sheets and valuation adjustment account in foreclosed real estate expense, net, a component of non-interest expense on the consolidated statements of income.

Synovus' objective is to dispose of ORE properties in a timely manner and to maximize net sale proceeds. Synovus has a centralized managed assets division, with the specialized skill set to facilitate this objective. While there is not a defined timeline for their sale, ORE properties are actively marketed through unaffiliated third parties.

Other Assets

Other assets include accrued interest receivable and other significant balances as described below.

Investments in Company-Owned Life Insurance Policies

Investments in company-owned life insurance policies on certain current and former officers of Synovus are recorded at the net realizable value of the policies as a component of other assets in the consolidated balance sheets. Net realizable value is the cash surrender value of the policies less any applicable surrender charges and any policy loans. Synovus has not borrowed against the cash surrender value of these policies. The changes in the cash surrender value of the policies is recognized as a component of other non-interest income in the consolidated statements of income.

Servicing Asset on SBA/Government Guaranteed Loans

Synovus has retained servicing responsibilities on sold SBA/government guaranteed loans and receives annual servicing fees on the outstanding loan balances.  SBA/government guaranteed loan servicing rights are accounted for using the amortization method.  A servicing asset is established at fair value at the time of the sale using a discounted future cash flow model.  The servicing asset is then amortized in other non-interest expense.

Private Equity Investments

Private equity investments are recorded at fair value on the consolidated balance sheets with realized and unrealized gains and losses recorded on the consolidated statements of income (as a component of other non-interest income) in accordance with ASC 946, Financial Services-Investment Companies. The private equity investments in which Synovus holds a limited partner interest consist of funds that invest in privately held companies. For privately held companies in the fund, the general partner estimates the fair value of the company in accordance with U.S. GAAP as clarified by ASC 820, Fair Value Measurements and Disclosures. The estimated fair value of the company is the estimated fair value as an exit price the fund would receive if it were to sell the company in the marketplace. The fair value of the fund's underlying investments is estimated through the use of valuation models, such as option pricing or a discounted cash flow model. Valuation factors, such as a company's financial performance against budget or milestones, last price paid by investors, with consideration given on whether financing is provided by insiders or unrelated new investors, public market comparables, liquidity of the market, industry and economic trends, and changes in management or key personnel, are used in the determination of estimated fair value.

Derivative Instruments

Synovus’ risk management policies emphasize the management of interest rate risk within acceptable guidelines. Synovus’ objective in maintaining these policies is to limit volatility in net interest income arising from changes in interest rates. Risks to be managed include both fair value and cash flow risks. Utilization of derivative financial instruments provides a valuable tool to assist in the management of these risks.

In accordance with ASC 815, Derivatives and Hedging, all derivative instruments are recorded on the consolidated balance sheets at their respective fair values, as components of other assets and other liabilities. The accounting for changes in fair value (i.e., unrealized gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and, if so, on the reason for holding it. If certain conditions are met, entities may elect to designate a derivative instrument as a hedge of exposures to changes in fair values, cash flows, or foreign currencies. If the hedged exposure is a fair value exposure, the unrealized gain or loss on the derivative instrument is recognized in earnings in the period of change, together with the offsetting unrealized loss or gain on the hedged item attributable to the risk being hedged as a component of other non-interest income on the consolidated statements of income. If the hedged exposure is a cash flow exposure, the effective portion of the gain or loss on the derivative instrument is reported initially as a component of accumulated other comprehensive income (loss), net of the tax impact, and subsequently reclassified into earnings when the hedged transaction affects earnings. Any amounts excluded from the assessment of hedge effectiveness, as well as the ineffective portion of the gain or loss on the derivative instrument, are reported in earnings immediately as a component of other non-interest income on the consolidated statements of income. If the derivative instrument is not designated as a hedge, the gain or loss on the derivative instrument is recognized in earnings as a component of other non-interest income on the consolidated statements of income in the period of change.

With the exception of certain commitments to fund and sell fixed-rate mortgage loans and derivatives utilized to meet the financing and interest rate risk management needs of its customers, all derivatives utilized by Synovus to manage its interest rate sensitivity are designated as either a hedge of a recognized fixed-rate asset or liability (fair value hedge), or a hedge of a forecasted transaction or of the variability of future cash flows of a floating rate asset or liability (cash flow hedge). Synovus does not speculate using derivative instruments.

In 2005, Synovus entered into certain forward starting swap contracts to hedge the cash flow risk of certain forecasted interest payments on a forecasted debt issuance. Upon the determination to issue debt, Synovus was potentially exposed to cash flow risk due to changes in market interest rates prior to the placement of the debt. The forward starting swaps allowed Synovus to hedge this exposure. Upon placement of the debt, these swaps were cash settled concurrent with the pricing of the debt. The effective portion of the cash flow hedge included in accumulated other comprehensive income is being amortized over the life of the debt issue as an adjustment to interest expense.

Synovus also holds derivative instruments, which consist of rate lock agreements related to expected funding of fixed-rate mortgage loans to customers (interest rate lock commitments) and forward commitments to sell mortgage-backed securities and individual fixed-rate mortgage loans. Synovus’ objective in obtaining the forward commitments is to mitigate the interest rate risk associated with the interest rate lock commitments and the mortgage loans that are held for sale. Both the interest rate lock commitments and the forward commitments are reported at fair value, with adjustments recorded in current period earnings in mortgage banking income.

Synovus also enters into interest rate swap agreements to facilitate the risk management strategies of certain commercial banking customers. Synovus mitigates this risk by entering into equal and offsetting interest rate swap agreements with highly rated third-party financial institutions. The interest rate swap agreements are free-standing derivatives and are recorded at fair value with any unrealized gain or loss recorded in current period earnings in other non-interest income. These instruments, and their offsetting positions, are recorded in other assets and other liabilities on the consolidated balance sheets.

When using derivatives to hedge fair value and cash flow risks, Synovus exposes itself to potential credit risk from the counterparty to the hedging instrument. This credit risk is generally a small percentage of the notional amount and fluctuates as interest rates change. Synovus analyzes and approves credit risk for all potential derivative counterparties prior to execution of any derivative transaction. Synovus seeks to minimize credit risk by dealing with highly rated counterparties and by obtaining collateralization for exposures above certain predetermined limits. If significant counterparty risk is determined, Synovus adjusts the fair value of the derivative recorded asset balance to consider such risk.

Non-interest Income

Service Charges on Deposit Accounts

Service charges on deposit accounts consist of non-sufficient funds fees, account analysis fees, and other service charges on deposits which consist primarily of monthly account fees. Non-sufficient funds fees are recognized at the time when the account overdraft occurs in accordance with regulatory guidelines. Account analysis fees consist of fees charged to certain commercial demand deposit accounts based upon account activity (and reduced by a credit which is based upon cash levels in the account). These fees, as well as monthly account fees, are recorded under the accrual method of accounting.

Fiduciary and Asset Management Fees

Fiduciary and asset management fees are generally determined based upon fair values of assets under management as of a specified date during the period. These fees are recorded under the accrual method of accounting as the services are performed.

Brokerage and Investment Banking Revenue

Brokerage revenue consists primarily of commission income, which represents the spread between buy and sell transactions processed, and net fees charged to customers on a transaction basis for buy and sell transactions processed. Commission income is recorded on a trade-date basis. Brokerage revenue also includes portfolio management fees, which represent monthly fees charged on a contractual basis to customers for the management of their investment portfolios and are recorded under the accrual method of accounting.

Investment banking revenue represents fees for services arising from securities offerings or placements in which Synovus acts as an agent. It also includes fees earned from providing advisory services. Revenue is recognized at the time the underwriting is completed and the revenue is reasonably determinable.

Bankcard Fees

Bankcard fees consist primarily of interchange fees earned, net of fees paid, on debit card and credit card transactions. Net fees are recognized into income as they are collected.

Advertising Costs

Advertising costs are expensed as incurred and recorded as a component of non-interest expense.

Income Taxes

Synovus is a domestic corporation that files a consolidated federal income tax return with its wholly-owned subsidiaries and files state income tax returns on a consolidated and a separate entity basis with the various taxing jurisdictions based on its taxable presence. Synovus accounts for income taxes in accordance with ASC 740, Income Taxes. The current income tax accrual or receivable is an estimate of the amounts owed to or due from taxing authorities in which Synovus conducts business. It also includes increases and decreases in the amount of taxes payable for uncertain tax positions reported in tax returns for the current and/or prior years.

Synovus uses the asset and liability method to account for future income taxes expected to be paid or received (i.e., deferred income taxes). Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement (GAAP) carrying amounts of existing assets and liabilities and their respective tax bases, including operating losses and tax credit carryforwards. The deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in income tax rates is recognized in income in the period that includes the enactment date.

A valuation allowance is required for deferred tax assets if, based on available evidence, it is more likely than not that all or some portion of the asset will not be realized. In making this assessment, all sources of taxable income available to realize the deferred tax asset are considered, including taxable income in prior carryback years, future reversals of existing temporary differences, tax planning strategies, and future taxable income exclusive of reversing temporary differences and carryforwards. The predictability that future taxable income, exclusive of reversing temporary differences, will occur is the most subjective of these four sources. Changes in the valuation allowance are recorded through income tax expense.

Significant estimates used in accounting for income taxes relate to the valuation allowance for deferred tax assets, estimates of the realizability of income tax credits, utilization of net operating losses, the determination of taxable income, and the determination of temporary differences between book and tax bases.

Synovus accrues tax liabilities for uncertain income tax positions based on current assumptions regarding the expected outcome by weighing the facts and circumstances available at the reporting date. If related tax benefits of a transaction are not more likely than not of being sustained upon examination, Synovus will accrue a tax liability or reduce a deferred tax asset for the expected tax impact associated with the transaction. Events and circumstances may alter the estimates and assumptions used in the analysis of its income tax positions and, accordingly, Synovus' effective tax rate may fluctuate in the future. Synovus recognizes accrued interest and penalties related to unrecognized income tax benefits as a component of income tax expense.

Share-based Compensation

Synovus has a long-term incentive plan under which the Compensation Committee of the Board of Directors has the authority to grant share-based awards to Synovus employees. Synovus' share-based compensation costs associated with employee grants are recorded as a component of salaries and other personnel expense in the consolidated statements of income. Share-based compensation costs associated with grants made to non-employee directors of Synovus are recorded as a component of other operating expenses. Share-based compensation expense for service-based awards that contain a graded vesting schedule is recognized net of estimated forfeitures for plan participants on a straight-line basis over the requisite service period for the entire award.

Earnings Per Share

Basic net income per common share is computed by dividing net income available to common shareholders by the average common shares outstanding for the period. Diluted net income per common share reflects the dilution that could occur if securities or other contracts to issue common stock were exercised or converted. The dilutive effect of outstanding options and restricted share units is reflected in diluted net income per common share, unless the impact is anti-dilutive, by application of the treasury stock method.

All share and per share amounts for all periods presented in this Report reflect the one-for-seven reverse stock split, which was effective on May 16, 2014.

Fair Value Measurements and Disclosures

Fair value estimates are made at a specific point in time, based on relevant market information and other information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale, at one time, the entire holdings of a particular financial instrument. Because no market exists for a portion of the financial instruments, fair value estimates are also based on judgments regarding estimated cash flows, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Synovus employs independent third-party pricing services to provide fair value estimates for its investment securities available for sale, trading account assets, and derivative financial instruments. Fair values for fixed income investment securities and certain derivative financial instruments are typically the prices supplied by either the third-party pricing service or an unrelated counterparty, which utilize quoted market prices, broker/dealer quotations for identical or similar securities, and/or inputs that are observable in the market, either directly or indirectly, for substantially similar securities. Level 1 securities are typically exchange quoted prices. Level 2 securities are typically matrix priced by a third-party pricing service to calculate the fair value. Such fair value measurements consider observable data, such as relevant broker/dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayments speeds, credit information, and the respective terms and conditions for debt instruments. Level 3 instruments' value is determined using pricing models, discounted cash flow models and similar techniques, and may also include the use of market prices of assets or liabilities that are not directly comparable to the subject asset or liability. These methods of valuation may result in a significant portion of the fair value being derived from unobservable assumptions that reflect Synovus' own estimates for assumptions that market participants would use in pricing the asset or liability.

Management uses various validation procedures to validate the prices received from pricing services and quotations received from dealers are reasonable for each relevant financial instrument, including reference to relevant broker/dealer quotes or other market quotes and a review of valuations and trade activity of comparable securities. Consideration is given to the nature of the quotes (e.g., indicative or firm) and the relationship of recently evidenced market activity to the prices provided by the third-party pricing service. Further, management also employs the services of an additional independent pricing firm as a means to verify and confirm the fair values of its primary independent pricing firm.

Understanding the third-party pricing service's valuation methods, assumptions and inputs used by the firm is an important part of the process of determining that reasonable and reliable fair values are being obtained. Management evaluates quantitative and qualitative information provided by the third-party pricing services to assess whether they continue to exhibit the high level of expertise and internal controls that management relies upon.

Fair value estimates are based on existing financial instruments on the consolidated balance sheet, without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Significant assets and liabilities that are not considered financial instruments include deferred income taxes, premises and equipment, equity method investments, goodwill and other intangible assets. In addition, the income tax ramifications related to the realization of the unrealized gains and losses on available for sale investment securities and cash flow hedges can have a significant effect on fair value estimates and have not been considered in any of the estimates.

Contingent Liabilities and Legal Costs

Synovus estimates its contingent liabilities with respect to outstanding legal matters based on information currently available to management, management’s estimates about the probability of outcomes of each case and the advice of legal counsel. In accordance with guidance in ASC 450-25-2, management accrues an estimated loss from a loss contingency when information available indicates that it is probable that a loss has been incurred and the amount of the loss can be reasonably estimated. In addition, it must be probable that one or more future events will occur confirming the fact of the loss. Significant judgment is required in making these estimates and management must make assumptions about matters that are highly uncertain. Accordingly, the actual loss may be more or less than the current estimate.

In many situations, Synovus may be unable to estimate reasonably possible losses due to the preliminary nature of the legal matters, as well as a variety of other factors and uncertainties. As there are further developments, Synovus will reassess these legal matters and the related potential liabilities and will revise, when needed, its estimate of contingent liabilities.

Legal costs, including attorney fees, incurred in connection with pending litigation and other loss contingencies are expensed as incurred.

Recently Adopted and Issued Accounting Standards Updates

Recently Adopted Accounting Standards Updates

In January 2014, the FASB issued amended guidance, ASU 2014-01, Investments-Equity Method and Joint Ventures (Topic 323), Accounting for Investments in Qualified Affordable Housing Projects, which permits Synovus to make an accounting policy election to account for its investments in qualified affordable housing projects using a proportional amortization method, if certain conditions are met, and to present the amortization as a component of income tax expense. The amended guidance would be applied retrospectively to all periods presented and is effective for fiscal years, and interim periods within those years, beginning after December 15, 2014. Regardless of the policy election, the amended guidance, where disclosed, enables users of the financial statements to understand the nature of investments in qualified affordable housing projects and the effect of the measurement of the investments in qualified affordable housing projects and the related tax credits on Synovus' financial position and results of operations.

Synovus adopted the amended guidance on January 1, 2015, and did not make an accounting policy election to apply the proportional amortization method for its investments in qualified affordable housing projects because the impact to the consolidated financial statements was insignificant. Therefore, the adoption did not have an impact on Synovus' consolidated financial statements. At December 31, 2015, the aggregate carrying value of Synovus' investments in LIHTC partnerships was $18.9 million. See Note 16 "Variable Interest Entities" to the consolidated financial statements of Synovus' 2015 Form 10-K for additional information regarding these investments.

Synovus early adopted ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs, during the the fourth quarter of 2015. This ASU was issued to simplify the presentation of debt issuance costs. Under previous accounting standards, debt issuance costs were reported on the balance sheet as assets and amortized as interest expense. ASU 2015-03 requires that debt issuance costs be presented on the balance sheet as a direct deduction from the carrying amount of the related liability, which is similar to the presentation of debt discounts or premiums. The costs will continue to be amortized to interest expense using the effective interest method. The cost of issuing debt will no longer be recorded as a separate asset, except when incurred before receipt of the funding from the associated debt liability. All prior periods presented in this Report have been adjusted to reflect adoption of ASU 2015-03 with updates to long-term debt and other assets. Adoption of ASU 2015-03 did not have a material impact on Synvous' consolidated financial statements.

Additionally, adoption of the following standards effective January 1, 2015, did not have a significant impact on Synovus' consolidated financial statements:

•ASU 2014-14, Classification of Certain Government-Guaranteed Mortgage Loans Upon Foreclosure

•ASU 2014-12, Accounting for Share-Based Payments when the Terms of an Award Provide that a Performance

Target Could be Achieved after the Requisite Service Period

•ASU 2014-11, Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures

•ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity

•ASU 2014-04, Receivables-Troubled Debt Restructurings by Creditors (Subtopic 310-40), Reclassification of

Residential Real Estate Collateralized Consumer Mortgage Loans Upon Foreclosure

ŸASU 2015-05, Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-

Credit Arrangements

Recently Issued Accounting Standards Updates

The following ASUs will be implemented effective January 1, 2016 or later:

ASU 2014-09, "Revenue from Contracts with Customers" - ASU 2014-09 establishes a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The standard is intended to increase comparability across industries and jurisdictions. The core principle of the revenue model is that a company will recognize revenue when it transfers control of goods or services to customers at an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services.

The FASB issued ASU 2015-14, Revenue From Contracts with Customers – Deferral of the Effective Date, in August 2015 to defer the effective date of ASU 2014-09 for one year. The proposed new effective date will be annual reporting periods beginning after December 15, 2017, and interim periods within that year, for public business entities. As such, for Synovus, the ASU will be effective on January 1, 2018. Earlier application will be permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period.

Management is currently evaluating the impact of ASU 2014-09 on Synovus' consolidated financial statements. The standard is expected to potentially impact ORE sales, interchange revenue, credit card loyalty programs, uncollectible credit card interest and fees, asset managers’ performance fees, treasury management services revenue, and miscellaneous fees; however the overall

financial statement impact for Synovus is not expected to be material. Extensive new disclosures will be required, including disaggregation of total revenue, information about performance obligations, changes in contract asset and liability account balances

between periods, and information about key judgments and estimates and policy decisions regarding revenue recognition.

ASU 2015-02, "Amendments to the Consolidation Analysis" - ASU 2015-02 was issued by the FASB to modify the analysis that companies must perform in order to determine whether a legal entity should be consolidated. ASU 2015-02 simplifies current consolidation rules by reducing the number of consolidation models; placing more emphasis on risk of loss when determining a controlling financial interest; reducing the frequency of the application of related-party guidance when determining a controlling financial interest in a variable interest entity (VIE); and changing consolidation conclusions for public and private companies in several industries that typically make use of limited partnerships or VIEs. ASU 2015-02 will be effective for the first quarter of 2016 for Synovus. Management does not expect the adoption of this ASU to have a material impact on the consolidated financial statements of Synovus.

Reclassifications

Prior years' consolidated financial statements are reclassified whenever necessary to conform to the current year's presentation.

Subsequent Events

Synovus has evaluated for consideration, or disclosure, all transactions, events, and circumstances, subsequent to the date of the consolidated balance sheet and through the date the accompanying audited consolidated financial statements were issued, and has reflected, or disclosed, those items deemed appropriate within the consolidated financial statements and related footnotes.

^{(1 )} Based on an analysis of the nature and risks of these investments, Synovus has determined that presenting these investments as a single asset class is appropriate.

^{(2 )} Mortgage derivatives consist of customer interest rate lock commitments that relate to the potential origination of mortgage loans, which would be classified as held for sale and forward loan sales commitments with third-party investors.

Changes in Fair Value Included in Consolidated Statements of Income

The following table summarizes the difference between the fair value and the unpaid principal balance of mortgage loans held for sale measured at fair value and the changes in fair value of these loans. Mortgage loans held for sale are initially measured at fair value with subsequent changes in fair value recognized in earnings. Changes in fair value were recorded as a component of mortgage banking income in the consolidated statements of income. An immaterial portion of these changes in fair value was attributable to changes in instrument-specific credit risk.

Transfers between fair value levels are recognized at the end of the reporting period in which the associated changes in inputs occur. During 2015 and 2014, Synovus did not have any transfers between levels in the fair value hierarchy.

Fair Value Inputs, Assets, Quantitative Information

The tables below provide an overview of the valuation techniques and significant unobservable inputs used in those techniques to measure financial instruments that are classified within Level 3 of the valuation hierarchy. The range of sensitivities that management utilized in its fair value calculations is deemed acceptable in the industry with respect to the identified financial instruments. The tables below present both the total balance as of the dates indicated for assets measured at fair value on a recurring basis and the assets measured at fair value on a non-recurring basis for which there was a fair value adjustment during the period.

Risk-free interest rate	1.11	%
Expected stock price volatility	50.0
Dividend yield	1.6
Expected life of options	6.0 years

The fair value of market restricted share units granted was estimated on the date of grant using a Monte Carlo simulation model with the following weighted average assumptions:

	2015		2014		2013
Risk-free interest rate	1.05	%	0.70	%	0.63	%
Expected stock price volatility	26.4		39.2		40.0
