1. Basis of Presentation

Nature of Operations and Principles of Consolidation

Capital Bank Financial Corp. (“CBF” or the “Company”; formerly known as North American Financial Holdings, Inc.) is a bank holding company incorporated in late 2009 in Delaware and headquartered in North Carolina whose business is conducted primarily through Capital Bank Corporation (“Capital Bank Corporation” or the “Bank”). The Company was incorporated with the goal of creating a regional banking franchise in the southeastern region of the United States through organic growth and acquisitions of other banks, including failed, underperforming and undercapitalized banks. CBF has raised $955.6 million to make acquisitions through a series of private placements and an initial public offering of its common stock. Since inception, CBF has acquired eight depository institutions, including the assets and certain deposits from failed banks. CBF has a total of 189 full service banking offices located in Florida, North and South Carolina, Tennessee and Virginia. During the six months endedJune 30, 2017, the Company closed and consolidated seven branches in conjunction with the merger of CommunityOne. The Company expects to close and consolidate an additional elevenbranches during 2017. As such, the Company transferred $18.1 million from fixed assets to bank properties held for sale during the six months endedJune 30, 2017.

The accompanying unaudited Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and Regulation S-X. Accordingly, they do not include all of the information and disclosures required by U.S. GAAP for complete financial statement presentation. In the opinion of management, all adjustments consisting of normal recurring accruals and disclosures considered necessary for a fair interim presentation have been included. All significant inter-company accounts and transactions have been eliminated in consolidation. For further information, refer to the Company’s Consolidated Financial Statements and notes thereto included in the Company’s annual report on Form 10-K for the fiscal year ended December 31, 2016.

Proposed merger with First Horizon National Corporation

On May 4, 2017, Capital Bank Financial Corp. issued a press release announcing the execution of an agreement and plan of merger with First Horizon National Corporation (the “First Horizon”) dated May 3, 2017, with First Horizon as the surviving corporation. Subject to terms and conditions of the Merger Agreement, each holder of Capital Bank common stock will be entitled to receive cash or stock with a value equivalent to 1.750 First Horizon shares and $7.90 in cash for each Capital Bank share held, subject to the election allocation and proration provisions of the merger agreement. The transaction is subject to shareholder and regulatory approvals in addition to satisfying certain other closing conditions.

Use of Estimates and Assumptions

To prepare financial statements in conformity with U.S. GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as presented in the financial statements. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ.

Recent Accounting Pronouncements

In March 2017, the Financial Accounting Standard Board (the “FASB”) issued Accounting Standards Update ("ASU") 2017-09, "Compensation—Stock Compensation (Topic 718)". The amendments in this update provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. An entity should account for the effects of a modification unless all the following are met: (1) the fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the modified award is the same as the fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the original award immediately before the original award is modified. If the modification does not affect any of the inputs to the valuation technique that the entity uses to value the award, the entity is not required to estimate the value immediately before and after the modification, (2) the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified, (3) the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2017. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In March 2017, the FASB issued ASU 2017-08, "Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20) Premium Amortization on Purchased Callable Debt Securities". The amendments in this update affect all entities that have an amortized cost basis in excess of the amount that is repayable by the issuer at the earliest call date. The objective is to shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. Securities held at a discount continue to be amortized to maturity. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2018. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In March 2017, the FASB issued ASU 2017-07, "Compensation - Retirement Benefits (Topic 715)". The amendments in this update require that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost as defined in paragraphs 715-30-35-4 and 715-60-35-9 are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. If a separate line item or items are used to present the other components of net benefit cost, that line item or items must be appropriately described. If a separate line item or items are not used, the line item or items used in the income statement to present the other components of net benefit cost must be disclosed. The amendments in this update also allow only the service cost component to be eligible for capitalization when applicable (for example, as a cost of internally manufactured inventory or a self-constructed asset). The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2017. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In January 2017, the FASB issued ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350)". The amendments in this update aim to simplify the subsequent measurement of goodwill. Under these amendments, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. The FASB also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment. An entity is required to disclose the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets and still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2019. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In January 2017, the FASB issued ASU 2017-01, "Business Combinations (Topic 805)". The amendments in this update provide a screen to determine when a set is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The amendments in this update should be applied prospectively on or after the effective date. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In May 2016, the FASB issued ASU 2016-12, "Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients". The amendments in this Update represent minor corrections or improvements to narrow aspects of Topic 606, as amended by ASU No. 2014-09, and do not change the core principle of the guidance in Topic 606. The effective date and transition requirements for the amendments in this Update are the same as the effective date and transition requirements for Topic 606 (and any other Topic amended by Update 2014-09), which is not yet effective. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows—Credit Losses (Topic 230)". The amendments in this update provide guidance on the following eight specific cash flow issues: (1) Debt prepayment or debt extinguishment costs; (2) Settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; (3) Contingent consideration payments made after a business combination; (4) Proceeds from the settlement of insurance claims; (5) Proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; (6) Distributions received from equity method investees; (7) Beneficial interests in securitization transactions; (8) Separately identifiable cash flows and application of the predominance principle. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments—Credit Losses (Topic 326)". The main objective of this update is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates and affects loans, debt securities, trade receivables, net investments in leases, off-balance-sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. For public business entities that are U.S. Securities and Exchange Commission (SEC) filers, the amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In March 2016, the FASB issued ASU 2016-9, "Compensation—Stock compensation (Topic 718)". Improvements to employee share-based payment accounting" which objective is the simplification through the identification, evaluation, and improvement of areas of generally accepted accounting principles (GAAP) for which cost and complexity can be reduced while maintaining or improving the usefulness of the information provided to users of financial statements. The areas for simplification involve several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Some of the areas for simplification apply only to nonpublic entities. We early adopted ASU 2016-09 during the fourth quarter of 2016 and prior periods were modified retrospectively. The adoption did not have a material impact on the Company's consolidated financial statements. The impact resulted in, among other items, a $0.1 million increase to net income and a $0.01 increase to earnings per share for the six months endedJune 30, 2016. The Company reflected these adjustments in our disclosures including the consolidated financial statements, earnings per common share, business combination and acquisitions, stock-based compensation, and income taxes.

In March 2016, the FASB issued ASU No. 2016-08, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net)”. The amendments in this update will clarify the implementation guidance on principal versus agent considerations. Topic 606 requires an entity to determine whether the nature of its promise is to provide that good or service to the customer (that is, the entity is a principal) or to arrange for the good or service to be provided to the customer by the other party (that is, the entity is an agent). This determination is based upon whether the entity controls the good or the service before it is transferred to the customer. Topic 606 includes indicators to assist in this evaluation. The effective date and transition requirements for the amendments in this update are the same as the effective date and transition requirements for Topic 606 (and any other Topic amended by update 2014-09 listed below), which is not yet effective. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In March 2016, the FASB issued ASU 2016-7, "Investments—Equity Method and Joint Ventures (Topic 323)". The amendments in this update eliminate the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments in this update require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The amendments in this update are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The amendments should be applied prospectively upon their effective date to increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. Earlier application is permitted. The adoption did not have a material impact on the Company's consolidated financial statements.

In March 2016, the FASB issued ASU 2016-6, "Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments". The amendments in this update clarify the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments in this update is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. For public business entities, the amendments in this update are effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The adoption did not have a material impact on the Company's consolidated financial statements.

In January 2016, the FASB issued ASU 2016-2, "Leases (Topic 842)" which increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. To meet that objective, the FASB is amending the FASB Accounting Standards Codification and creating Topic 842, Leases. This update, along with IFRS 16, Leases, are the results of the FASB’s and the International Accounting Standards Board’s (IASB’s) efforts to meet that objective and improve financial reporting. The FASB and IASB decided to not fundamentally change lessor accounting with the amendments in this update. However, some changes have been made to lessor accounting to conform and align that guidance with the lessee guidance and other areas within generally accepted accounting principles (GAAP), such as Topic 606, Revenue from Contracts with Customers. The main difference between previous GAAP and Topic 842 is the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. For public business entities, the amendments in ASU 2016-2 are effective for fiscal years beginning after December 15, 2018. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In January 2016, the FASB issued ASU 2016-1, "Financial instruments—Overall (Subtopic 825-10)" which requires all equity investments to be measured at fair value with changes in the fair value recognized through net income (other than those accounted for under equity method of accounting or those that result in consolidation of the investee). The amendments in this update also require an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. In addition, the amendments in this update eliminate the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities and the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet for public business entities. For public business entities, the amendments in ASU 2016-1 are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of ASU 2016-1 is not expected to have a material impact on the Company's consolidated financial position, results of operations and cash flows.

In May 2014, the FASB issued ASU 2014-9, "Revenue from Contracts with Customers (Topic 606)". The core principle of Topic 606 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies the performance obligation. In August 2015, the FASB issued ASU 2015-14, "Revenue from contracts with customers (Topic 606) - Deferral of the Effective Date". The amendments in ASU 2015-14 establish December 15, 2017 as the effective date of the information related to ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)”. While we anticipate some changes, the Company does not expect a material change from our current accounting for revenue as the majority of our interest and non-interest income is not in scope of Topic 606.

2. Earnings Per Common Share

Basic earnings per share is computed as net income attributable to common shareholders divided by the weighted average number of common shares outstanding during the period. Diluted earnings per share include the dilutive effect of additional potential common shares issuable under stock options and unvested restricted shares computed using the treasury stock method. Earnings per share have been computed based on the following:

8

(Shares in thousands)	Three Months Ended		Six Months Ended
	June 30, 2017	June 30, 2016	June 30, 2017	June 30, 2016
Weighted average number of shares outstanding:
Basic	51,683	43,011	51,659	43,036
Dilutive effect of options outstanding	1,478	1,041	1,501	1,030
Dilutive effect of unvested restricted shares	65	16	54	8
Diluted	53,226	44,068	53,214	44,074

The dilutive effect of stock options and unvested restricted shares are the only common stock equivalents for purposes of calculating diluted earnings per common share.

Weighted average anti-dilutive stock options and unvested restricted shares excluded from the computation of diluted earnings per share are as follows:

(Shares in thousands)	Three Months Ended		Six Months Ended
	June 30, 2017	June 30, 2016	June 30, 2017	June 30, 2016
Anti-dilutive stock options	—	38	3	38
Anti-dilutive unvested restricted shares	—	3	14	2

3. Business Combinations and Acquisitions

Acquisition of CommunityOne Bancorp

On October 26, 2016, the Company completed its acquisition of CommunityOne Bancorp (“CommunityOne”) whereby CommunityOne merged with and into the Company. CommunityOne was a North Carolina-based bank with $2.4 billion in assets and 45 full service banking branches as of October 26, 2016. The combination will strengthen Capital Bank’s franchise in North Carolina, particularly in Charlotte, as well as in Greensboro/Winston Salem and the Catawba/Caldwell county area.

The Company acquired 100% of the outstanding common stock of CommunityOne. The total purchase price for CommunityOne was $340.5 million, consisting of $51.9 million of cash, and the issuance of 8.9 million shares of Capital Bank Common Stock valued at $288.6 million based on the Company's stock on October 25, 2016.

The acquisition was accounted for under the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations. Accordingly, the Company recognizes amounts for identifiable assets acquired and liabilities assumed at their estimated acquisition date fair value, with any excess of purchase consideration over the net assets being reported as goodwill. As the fair value of consideration paid exceeded the estimated fair value of net assets acquired, nondeductible goodwill of $103.4 million was recorded. Fair value estimates are based on the information available, and are subject to change for up to one year after the closing date of the acquisition as additional information relative to the closing date fair values becomes available. During the three months endedJune 30, 2017, there were no changes to the acquisition date balance sheet. During the six months endedJune 30, 2017, the Company adjusted the acquisition date balance sheet to reflect (1) a $0.4 million increase due to a recovery on a fully charged off loan; (2) a $1.0 million increase in the deferred tax asset; and (3) a $1.3 million decrease in Goodwill caused by the net effect of these adjustments. These adjustments are reflected in the table below. Management continues to review initial estimates on certain areas such as loan valuations, core deposit intangibles and the deferred tax asset.

The following table summarizes the Company's investment and CommunityOne's opening balance sheet as of October 26, 2016 adjusted to their preliminary fair value:

Other liabilities	22,345
Total liabilities assumed	2,020,508
Net assets acquired	$	340,534

The following table summarizes the fair value of loans, the total contractual principal and interest payments, and management's estimate of expected total cash payments of purchase credit impaired loans:

(Dollars in thousands)	Fair Value of Acquired Loans		Gross Contractual Amounts Receivable		Best Estimate of Contractual Cash Flows not to be Collected
Loans acquired subject to ASC 310-30	$	129,075	$	182,927	$	34,219

In addition, the Bank acquired loans of $1.4 billion not determined to be purchase credit impaired at the time of acquisition. These loans have an estimated cash flow of $1.6 billion and management expects to collect contractual required payments from the borrower with similar characteristics as other non-impaired loans.

In the assumption of deposit liabilities, the Company estimated the fair value of the core deposits intangible asset to be $19.9 million, which will be amortized utilizing an accelerated amortization method over an estimated economic life of 10 years. Fair value estimates are based on factors such as type of deposit, retention rates, interest rates and customer relationships.

Pro-forma financial information

Pro-forma data for the six months ended and June 30, 2016 listed in the table below presents pro-forma information as if the CommunityOne acquisition occurred at the beginning of 2016.

As of June 30, 2017, the Company’s security portfolio consisted of 175 securities, 75 of which were in an unrealized loss position. The majority of unrealized losses are related to the Company’s mortgage-backed securities.

The corporate bonds in an unrealized loss position at June 30, 2017 and December 31, 2016 continue to perform and are expected to perform through maturity. Unrealized losses associated with these securities are primarily due to changes in interest rates and market volatility, and the corporate issuers have not experienced significant adverse events that would call into question their ability to repay those debt obligations according to contractual terms. Further, because the Company does not have the intent to sell these corporate bonds and it is more likely than not that it will not be required to sell the securities before their anticipated recovery of their amortized cost bases, the Company does not consider these securities to be other-than-temporarily impaired as of June 30, 2017 or December 31, 2016.

All of the mortgage-backed securities at June 30, 2017 and December 31, 2016 were issued by U.S. government-sponsored entities and agencies, which the government has affirmed its commitment to support. Unrealized losses associated with these securities are attributable to changes in interest rates and illiquidity, and not credit quality, and because the Company does not have the intent to sell these mortgage-backed securities and it is more likely than not that it will not be required to sell the securities before their anticipated recovery, the Company does not consider these securities to be other-than-temporarily impaired at June 30, 2017 or December 31, 2016.

Investment securities having carrying values of approximately $650.8 million and $621.8 million at June 30, 2017 and December 31, 2016, respectively, were pledged to secure public funds on deposit, securities sold under agreements to repurchase, and for other purposes as required by law.

1-4 family residential construction and land	153,761		140,030
Total commercial real estate	1,951,283		1,716,050
Owner occupied commercial real estate	1,287,811		1,321,405
Commercial and industrial	1,424,862		1,468,874
Total commercial	2,712,673		2,790,279
1-4 family residential	1,782,799		1,714,702
Home equity loans	489,497		507,759
Other consumer loans	395,807		448,972
Total consumer	2,668,103		2,671,433
Other	238,055		228,430
Total loans	$	7,570,114	$	7,406,192

Total loans include $3.5 million and $12.9 million of loans held for sale and $15.0 million and $15.5 million of net deferred loan origination costs and fees as of June 30, 2017 and December 31, 2016, respectively.

As of June 30, 2017, other loans include $42.9 million, $155.3 million and $1.3 million of farm land, state and political subdivision obligations and deposit customer overdrafts, respectively. As of December 31, 2016, other loans include $41.9 million, $149.0 million and $1.6 million of farm land, state and political subdivision obligations and deposit customer overdrafts, respectively.

The Company designates purchased credit impaired loans as "PCI" by evaluating both qualitative and quantitative factors. At the time of acquisition, the Company accounted for the PCI loans by segregating each portfolio into loan pools with similar risk characteristics. Over the lives of the acquired PCI loans, the Company continues to estimate cash flows expected to be collected on each loan pool. The Company evaluates, at each balance sheet date, whether its estimates of the present value of the cash flows from the loan pools, determined using the effective interest rates, has decreased, such that the present value of such cash flows is less than the recorded investment of the pool, and if so, recognizes a provision for loan loss in its Consolidated Statements of Income, unless related to non-credit events.

Additionally, if the Company has favorable changes in estimates of cash flows expected to be collected for a loan pool such that the then-present value exceeds the recorded investment of that pool, the Company will first reverse any previously established allowance for loan and lease losses for the pool. If such estimate exceeds the amount of any previously established allowance, the Company will accrete future interest income over the remaining life of the pool at a rate which, when used to discount the expected cash flows, results in the then-present value of such cash flows equaling the recorded investment of the pool at the time of the revised estimate.

The table below presents a roll forward of accretable yield and income expected to be earned related to PCI loans. The accretable yield represents the excess of estimated cash flows expected to be collected over the carrying amount of the PCI loans. Nonaccretable difference represents estimated contractually required payments in excess of estimated cash flows expected to be collected. Other represents reductions of accretable yield due to non-credit events such as prepayment activity on PCI loans.

Balance at end of period	$	145,419		$	170,935		$	145,419		$	170,935

The accretable yield is accreted into interest income over the estimated life of the PCI loans using the level yield method. The accretable yield will change due to changes in:

• The estimate of the remaining life of PCI loans which may change the amount of future interest income, and possibly principal, expected to be collected;

• The estimate of the amount of contractually required principal and interest payments over the estimated life that will not be collected (the nonaccretable difference); and

• Indices for PCI loans with variable rates of interest.

For PCI loans, the impact of loan modifications is included in the evaluation of expected cash flows for subsequent decreases or increases of cash flows. For variable rate PCI loans, expected future cash flows will be recalculated as the rates adjust over the lives of the loans. At acquisition, the expected future cash flows were based on the variable rates that were in effect at that time.

Credit Quality Indicators

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans as to credit risk. This analysis is performed at origination and upon identification of a material change for all loans, on an annual basis for commercial loans exceeding $0.5 million, and at least quarterly for commercial loans not rated pass. The Company uses the following definitions for risk ratings:

• Pass —These loans range from superior quality with minimal credit risk to loans requiring heightened management attention but that are still an acceptable risk and continue to perform as contracted.

• Special Mention —Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date.

• Substandard —Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.

• Doubtful —Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

The following table summarizes loans, excluding PCI loans, by internal rating at June 30, 2017:

For the three and six months endedJune 30, 2017 and June 30, 2016, the amount of interest income recognized on loans that were impaired was not material.

Troubled Debt Restructuring

If a borrower is experiencing financial difficulty, the Bank may consider, in certain circumstances, modifying the terms of their loan to maximize collection of amounts due. A troubled debt restructuring (“TDR”) typically involves either a reduction of the stated interest rate of the loan, an extension of the loan’s maturity date(s) with a stated rate lower than the current market rate for a new loan with similar risk, or in limited circumstances, a reduction of the principal balance of the loan or the loan’s accrued interest. Upon modification of a loan, the Bank measures the related impairment as the excess of the recorded investment in the loan over the discounted expected future cash flows. The present value of expected future cash flows is discounted at the loan’s effective interest rate. If the impairment analysis results in a loss, an allowance for loan and lease losses is established for the loan. During the six months endedJune 30, 2017 and 2016, loans modified in TDRs were nominal. Because of the insignificance of the amount and the nature of the modifications, the modifications did not have a material impact on the Company’s Consolidated Financial Statements or on the determination of the allowance for loan and lease losses at June 30, 2017 and 2016. The Company had loans modified in TDRs with recorded investments of $2.5 million, $2.7 million, and $1.8 million as of June 30, 2017, December 31, 2016 and June 30, 2016, respectively.

7. Other Real Estate Owned

The activity within Other Real Estate Owned (“OREO”) for the three and six months endedJune 30, 2017 and 2016 is presented in the table below.

For the three and six months endedJune 30, 2017 , proceeds on sales of OREO were $10.7 million and $15.6 million, respectively and net gains were $0.2 million and $0.5 million, respectively. For the three and six months ended June 30, 2016, proceeds on sales of OREO were $4.7 million and $11.8 million, respectively and net gains were $0.4 million and $1.1 million. respectively.

8. Federal Home Loan Bank Advances and Short-Term Borrowings

Short-term borrowings include securities sold under agreements to repurchase, cash received from counterparties as collateral for mark-to-market exposure on interest rate swaps, and advances from the Federal Home Loan Bank (“FHLB”) .

The Bank has securities sold under agreements to repurchase with customers. These overnight agreements are collateralized by investment securities of the United States Government or its agencies which are chosen by the Bank. The amounts outstanding at June 30, 2017 and December 31, 2016 were $32.4 million and $18.0 million, respectively, and were collateralized by $37.7 million and $27.6 million, respectively, of agency mortgage-backed securities.

The Bank has $0.3 million and $1.2 million of short term borrowings related to cash received from counterparties as collateral for mark-to-market exposure on interest rate swaps at June 30, 2017 and December 31, 2016, respectively.

The Bank invests in FHLB stock for the purpose of establishing credit lines with the FHLB. The credit availability to the Bank is based on a percentage of the Bank’s total assets as reported on the most recent quarterly financial information submitted to the regulators subject to the pledging of sufficient collateral. The Bank’s collateral with the FHLB consists of a blanket floating lien pledge of the Bank’s residential 1-4 family mortgage, multifamily, home equity line of credit and

27

commercial real estate secured loans. The amounts of eligible collateral at June 30, 2017 and December 31, 2016 provided for incremental borrowing availability of up to $482.6 million and $415.9 million, respectively.

At June 30, 2017 and December 31, 2016, the Bank had $15.3 million and $15.4 million in letters of credit issued by the FHLB respectively, of which $15.0 million and $15.2 million are used as collateral for public funds deposits in lieu of pledging securities to the State of Florida, respectively.

The FHLB advances as of June 30, 2017 and December 31, 2016 consisted of the following:

The Company is not considered the primary beneficiary of the trusts (variable interest entities), therefore the trusts are not consolidated in the Company’s Consolidated Financial Statements, but rather the subordinated debentures are presented as liabilities. The trusts consist of wholly-owned statutory trust subsidiaries for the purpose of issuing the trust preferred securities. The trusts used the proceeds from the issuance of trust preferred securities to acquire junior subordinated deferrable interest debentures of the Company. The trust preferred securities essentially mirror the debt securities, carrying a cumulative preferred dividend equal to the interest rate on the debt securities. The debt securities and the trust preferred securities each have 30-year lives. The trust preferred securities and the debt securities are callable by the Company or the trust, at their respective option after a period of time, and at varying premiums and sooner in specific events, subject to prior approval by the Federal Reserve Board (“FRB”), if then required. Deferral of interest payments on the trust preferred securities is allowed for up to 60 months without being considered an event of default.

The subordinated debentures are included in Tier 1 capital under the capital guidelines of the Dodd-Frank Act. The subordinated debentures as of June 30, 2017 and December 31, 2016 consisted of the following:

10. Shareholders’ Equity and Minimum Regulatory Capital Requirements

The Company (on a consolidated basis) and the Bank are subject to various regulatory capital requirements administered by federal and state banking agencies. Failure to meet minimum capital requirements results in certain discretionary and required actions by regulators that could have an effect on the Company’s operations. The regulations require the Company and the Bank to meet specific capital adequacy guidelines that involve quantitative measures of assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The Company’s capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.

To be considered well capitalized or adequately capitalized as defined under the regulatory framework for prompt corrective action, the Bank must maintain minimum Tier 1 leverage, Tier 1 common, Tier 1 risk-based and Total Risk-based ratios. At June 30, 2017 and December 31, 2016 the Bank maintained capital ratios exceeding the requirement to be considered well capitalized. These minimum ratios along with the actual ratios for the Company and the Bank are presented in the following tables:

As of June 30, 2017 and December 31, 2016, the Company and the Bank met all capital requirements to which they were subject. Tier 1 Capital for the Company includes trust preferred securities to the extent allowable.

Dividends that may be paid by a national bank are limited to that bank’s retained net profits for the preceding two years plus retained net profits up to the date of any dividend declaration in the current calendar year. The Company received dividends from the Bank totaling $6.8 million, $4.2 million, $6.1 million, $5.7 million, and $64.2 million, on May 2, 2017, January 31, 2017, January 24, 2017, October 19, 2016 and June 1, 2016, respectively. The Company may use these dividends for general corporate purposes including acquisitions, or as a return of capital to shareholders through future share repurchases or dividends.

In July 2013, the U.S. banking regulators adopted a final rule which implements the Basel III regulatory capital reforms from the Basel Committee on Banking Supervision, and certain changes required by the Dodd-Frank Act. The final rule established an integrated regulatory capital framework and introduces the “Standardized Approach” for risk-weighted assets, which replaces the Basel I risk-based guidance for determining risk-weighted assets as of January 1, 2015, the date the Company became subject to the new rules. Based on the Company's current capital composition and levels, the Company believes it is in compliance with the requirements as set forth in the final rules.

The rules include new risk-based capital and leverage ratios, which will be phased in from 2015 to 2019, and refine the definition of what constitutes “capital” for purposes of calculating those ratios. The new minimum capital level requirements applicable to the Company and the Bank under the final rules are as follows: (i) a new common equity Tier 1 capital ratio of 4.5%; (ii) a Tier 1 capital ratio of 6% (increased from 4%); (iii) a total capital ratio of 8% (unchanged from previous rules); and (iv) a Tier 1 leverage ratio of 4% for all institutions. The final rules also establish a “capital conservation buffer” above the new regulatory minimum capital requirements. The capital conservation buffer will be phased-in over four years beginning on January 1, 2016, as follows: the maximum buffer will be 0.625% of risk-weighted assets for 2016, 1.25% for 2017, 1.875% for 2018, and 2.5% for 2019 and thereafter. This will result in the following minimum ratios beginning in 2019: (i) a common equity Tier 1 capital ratio of 7.0%, (ii) a Tier 1 capital ratio of 8.5%, and (iii) a total capital ratio of 10.5%. Under the final rules, institutions are subject to limitations on paying dividends, engaging in share repurchases, and paying discretionary bonuses if its capital level falls below the buffer amount. These limitations establish a maximum percentage of eligible retained income that could be utilized for such actions. As of June 30, 2017, our capital buffer is 6.3%; exceeding the 2.5% 2019 requirement.

The final rules also contain revisions to the prompt corrective action framework, which is designed to place restrictions on insured depository institutions if their capital levels begin to show signs of weakness. Under the prompt corrective action requirements, which are designed to complement the capital conservation buffer, insured depository institutions are required to meet the following increased capital level requirements in order to qualify as “well capitalized:” (i) a

31

new common equity Tier 1 capital ratio of 6.5%; (ii) a Tier 1 capital ratio of 8% (increased from 6%); (iii) a total capital ratio of 10% (unchanged from previous rules); and (iv) a Tier 1 leverage ratio of 5% (unchanged from previous rules).

Dividend Program

On July 20, 2017, the Company's board of directors approved a quarterly common dividend of $0.12 per share payable on August 21, 2017, to shareholders of record as of August 7, 2017.

Share Repurchases

The Company’s board of directors has authorized stock repurchases of up to $400.0 million. Stock repurchases may be made from time to time, on the open market or in privately negotiated transactions. The approved stock repurchase program does not obligate the Company to repurchase any particular amount of shares, and the program may be extended, modified, suspended, or discontinued at any time.

As of June 30, 2017, the Company has repurchased a total of $312.4 million, or 12,739,763 common shares at an average price of $24.52 per share with $87.6 million remaining under the current board authorized stock repurchase program.

The Company accounts for treasury stock using the cost method as a reduction of shareholders’ equity in the accompanying Consolidated Balance Sheets and Statements of Changes in Shareholders’ Equity.

11. Stock-Based Compensation

As of June 30, 2017, the Company had two compensation plans, the 2010 Equity Incentive Plan (the "2010 Plan") and the 2013 Omnibus Compensation Plan (the “2013 Plan”) under which shares of its common stock are issuable in the form of stock options, stock appreciation rights, restricted stock, restricted stock units, stock awards, stock bonus awards, and other incentive awards. The 2010 Plan was replaced by the 2013 Plan and no further awards may be made pursuant to the 2010 Plan.

The 2013 Plan was effective May 22, 2013 and expires on May 22, 2023, the tenth anniversary of the effective date. The maximum number of shares of common stock of the Company that may be optioned or awarded under this plan is 2,639,000 shares. Awards under this plan may be made to any person selected by the Compensation Committee.

The following table summarizes the components and classification of stock-based compensation expense for the three and six months endedJune 30, 2017 and 2016:

(Dollars in thousands)	Three Months Ended				Six Months Ended
	June 30, 2017		June 30, 2016		June 30, 2017		June 30, 2016
Stock options	$	28	$	12	$	52	$	21
Restricted stock	936		455		1,812		763
Total stock-based compensation expense	$	964	$	467	$	1,864	$	784

The tax benefit related to stock-based compensation expense arising from restricted stock awards and non-qualified stock options was $362 thousand and $177 thousand for the three months endedJune 30, 2017 and 2016, respectively and $699 thousand and $298 thousand for the six months endedJune 30, 2017 and 2016, respectively.

Stock Options

Under the 2010 Plan and 2013 Plan, the exercise price for common stock must equal at least 100% of the fair market value of the stock on the day an option is granted. The exercise price under an incentive stock option granted to a person owning stock representing more than 10% of the common stock must equal at least 110% of the fair market value at the date of grant, and such option is not exercisable after five years from the date the incentive stock option was granted. The Board of Directors may, at its discretion, provide that an option not be exercised in whole or in part for any period or periods of time as specified in the option agreements. Stock options have an expiration of ten years from the date it is granted. Under these plans, 83,729 options were exercised and 15,623 stock options were granted during the six months endedJune 30, 2017.

The fair value of each option is estimated as of the date of the grant using the Black-Scholes Option Pricing Model. This model requires the input of subjective assumptions that will usually have a significant impact on the fair value estimate. The dividend yield assumption is consistent with management expectations of dividend distributions based upon the Company’s business plan at the date of grant. The risk-free interest rate was developed using the U.S. Treasury yield curve for a period equal to the expected life of the options on the grant date. The expected option life for the current period grants was estimated using the vesting period, the term of the option and estimates of future exercise behavior patterns. The expected volatility assumption was based on the historical volatility of the Company's stock price.

ASC 718 requires the recognition of stock-based compensation expense for the number of awards that are ultimately expected to vest. During the six months endedJune 30, 2017 and 2016, stock based compensation expense was recorded based upon assumptions that the Company would experience no forfeitures. This assumption of forfeitures will be reassessed in subsequent periods based on historical forfeiture rates and may change based on new facts and circumstances. Any changes in assumptions will be accounted for prospectively in the period of change.

A summary of the stock option activity for the six months endedJune 30, 2017 and 2016 is as follows:

33

	Six Months Ended
	June 30, 2017				June 30, 2016
(Shares in thousands)	Shares		Weighted     Average Exercise Price Per Share		Shares		Weighted     Average Exercise Price  Per Share

Balance, June 30,	3,108		$	20.92	3,076		$	20.23

At June 30, 2017, the weighted average remaining contractual life for outstanding stock options was approximately 3.34 years and the aggregate intrinsic values was $51.5 million for stock options outstanding and exercisable.

The intrinsic value for stock options is calculated as the difference between the exercise price of the underlying awards and the market price of the Company’s common stock as of the reporting date.

Options outstanding at June 30, 2017 were as follows:

(Shares in thousands)	Outstanding Options				Exercisable Options
Range of Exercise Prices	Shares	Weighted Average Remaining Contractual Life	Weighted Average Exercise Price Per Share		Shares	Weighted Average Exercise Price Per Share
$18.00	121	5.89 years	$	18.00	121	$	18.00
$18.01 - $20.00	2,819	2.98 years	20.00		2,819	20.00
$20.01 - $2,026.00	168	7.67 years	37.31		113	38.11
$18.00 - $2,026.00	3,108	3.34 years	$	20.85	3,053	$	20.59

Restricted Stock

Restricted stock provides the grantee with voting, dividend and anti-dilution rights equivalent to common shareholders, but is restricted from transfer until vested, at which time all restrictions are removed. The restricted stock vests ratably over a three-year period subject to continued employment with the company. The value of the restricted stock is being amortized on a straight-line basis over the implied service periods. There were 165,063 restricted stock awards granted under the 2013 Plan during the six months endedJune 30, 2017.

The following table summarizes unvested restricted stock activity for the six months endedJune 30, 2017 and 2016:

12. Income Taxes

A reconciliation of income tax computed at applicable Federal statutory income tax rates to total income tax expense reported for the three and six months endedJune 30, 2017 and 2016 is as follows:

(Dollars in thousands)	Three Months Ended						Six Months Ended
	June 30, 2017			June 30, 2016			June 30, 2017			June 30, 2016

Total income tax expense	$	14,148		$	10,288		$	25,138		$	16,048

The Company uses an estimated annual effective tax rate method of computing its interim tax provision. The effective tax rate is based on forecasted annual pre-tax income, permanent differences and statutory tax rates. For the three and six months endedJune 30, 2017, the effective income tax rates were 37% and 36%, respectively. For the three and six months endedJune 30, 2016, the effective income tax rates were 37%. The change in effective income tax rate was mainly due to higher state income taxes, higher tax exempt interest income and other favorable adjustments.

The Company and its subsidiaries are subject to U.S. federal income tax, as well as income tax of the states of Florida, New York, South Carolina, North Carolina, and Tennessee. The net deferred tax assets as of June 30, 2017 and December 31, 2016 were $134.5 million and $150.3 million, respectively. A valuation allowance related to deferred tax assets is required when it is considered more likely than not that all or part of the benefit related to such assets will not be realized. In assessing the need for a valuation allowance, the Company considered both positive and negative evidence in concluding that no valuation allowance was necessary at June 30, 2017 and December 31, 2016.

At June 30, 2017 and December 31, 2016, the Company had $464.6 million and $478.6 million of gross federal net operating loss carry-forwards, respectively, which begin to expire after 2028 and are subject to annual cumulative limitation of $27.8 million for tax year 2017.

At June 30, 2017 and December 31, 2016 the company had $506.5 million and $507.0 million of gross state net operating loss carry-forwards expected to be utilized, respectively.

At June 30, 2017 and December 31, 2016, the Company had no unrecognized tax benefits and no material amounts recorded for uncertain tax positions.

13. Fair Value

FASB guidance on fair value measurements defines fair value, establishes a framework for measuring fair value, and requires fair value disclosures for certain assets and liabilities measured at fair value on a recurring and non-recurring basis.

This guidance defines fair value as the exchange price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants in the principal or most advantageous market for the asset or liability.

This guidance establishes a fair value hierarchy for disclosure of fair value measurements to maximize the use of observable inputs, that is, inputs that reflect the assumptions market participants would use in pricing an asset or liability based on market data obtained from sources independent of the reporting entity. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity can access as of the measurement date.

Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.

Cash & cash equivalents

Cash and cash equivalents include cash on hand and highly-liquid items with an original maturity of three months or less. Accordingly, the carrying amount of such instruments is considered to be a reasonable estimate of fair value.

Derivative financial instruments

Interest rate swaps are valued by a third party, using models that primarily use market observable inputs, such as yield curves, and are validated by comparison with valuations provided by the respective counterparties. The credit risk associated with derivative financial instruments that are subject to master netting agreements is measured on a net basis by counterparty portfolio. Forward loan sales agreements are based upon the amounts required to settle the contracts. Fair values for commitments to originate loans held for sale are based on fees currently charged to enter into similar agreements. Fair values for fixed-rate commitments consider the difference between current levels of interest rates and the committed rates.

Valuation of Investment Securities

The fair values of available-for-sale, held-to-maturity and trading securities are determined by: 1) obtaining quoted prices on nationally recognized securities exchanges when available (Level 1 inputs); 2) matrix pricing, which is a mathematical technique widely used in the financial markets to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs); and 3) for certain other debt securities that are not actively traded, custom discounted cash flow modeling (Level 3 inputs).

As of June 30, 2017, the Bank held industrial revenue bonds, which are floating rate issues. Since there is no active secondary market for the trading of the bonds, the Company has developed a model to estimate fair value. This model determines an appropriate discount rate for the bonds based on current market rates for liquid corporate bonds with an equivalent credit rating plus an estimated illiquidity factor, and calculates the present value of expected future cash flows using this discount rate.

36

Mortgage Loans Held for Sale

Mortgage loans held for sale are carried at the lower of cost or estimated fair value. The fair values of mortgage loans held for sale are based on commitments on hand from investors within the secondary market for loans with similar characteristics. As such, the fair value adjustment for mortgage loans held for sale is classified as nonrecurring Level 2.

Valuation of Impaired Loans and Other Real Estate Owned

The fair value of collateral dependent impaired loans with specific allocations of the allowance for loan and lease losses and other real estate owned is generally based on recent real estate appraisals and other available observable market information. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach.

The Company generally uses independent external appraisers in this process who routinely make adjustments to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in a Level 3 classification of the inputs for determining fair value. The Company’s policy is to update appraisals, at a minimum, annually for classified assets, which include collateral dependent loans and OREO. The Company considers appraisals dated within the past 12 months to be current and do not typically make adjustments to such appraisals. In the Company’s process for reviewing third-party prepared appraisals, any differences of opinion on values, assumptions or adjustments to comparable sales data are typically reconciled directly with the independent appraiser prior to acceptance of the final appraisal.

Valuation of Premises and Equipment held for sale

Premises and equipment held for sale are carried at the lower of cost or estimated fair value. The fair values of premises and equipment held for sale are based on recent real estate appraisals and other available observable market information.

Mortgage Servicing Rights

As of June 30, 2017, the fair value of the Company's Level 3 mortgage servicing rights (“MSR”) was $2.5 million, none of which are currently impaired and therefore are carried at amortized cost. The assumptions used include the fee per loan, the cost to service, the expected loan prepayment rate, and the discount rate. In determining the fair value of the existing MSR, the Company reviews the key assumptions, analyzes pricing in the market for comparable MSR, and uses a third party provider to independently calculate the fair value of its MSR.

Sensitivity to Changes in Significant Unobservable Inputs

As discussed above, as of June 30, 2017, the Company owns industrial revenue bonds, which require recurring fair value estimates categorized within Level 3 of the fair value hierarchy. The significant unobservable inputs used in the fair value measurement of these securities are incorporated in the discounted cash flow modeling valuation. Rates utilized in the modeling of these securities are estimated based upon a variety of factors including the market yields of other non-investment grade corporate debt. Significant changes in any inputs in isolation would result in significantly different fair value estimates.

Assets and Liabilities Measured on a Recurring Basis

The methods and assumptions used to estimate fair value are described as follows:

Carrying amount is the estimated fair value for cash and cash equivalents, derivatives, noncontractual demand deposits and certain short-term borrowings. As it is not practicable to determine the fair value of Federal Home Loan Bank stock due to restrictions placed on transferability, the estimated fair value is equal to their carrying amount. Security fair values are based on market prices or dealer quotes and, if no such information is available, on the rate and term of the security and information about the issuer including estimates of discounted cash flows when necessary. For fixed rate loans or contractual deposits and for variable rate loans or deposits with infrequent repricing or repricing limits, fair value is based on discounted cash flows using current market rates applied to the estimated life, adjusted for the allowance for loan and lease losses. Fair values for impaired loans are estimated using discounted cash flow analysis or underlying collateral values. Fair value of loans does not necessarily represent exit price. Fair value of long-term debt is based on current rates for similar financing. The fair value of off-balance sheet items that include commitments to extend credit to fund commercial, consumer, real estate construction and real estate-mortgage loans and to fund standby letters of credit is considered nominal.

14. Derivative and Hedging Activities

The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates.

The Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. The Company may enter into derivative contracts that are intended to economically hedge certain of its risks, even though hedge accounting does not apply or the Company elects not to apply hedge accounting.

During 2015, the company entered into LIBOR-based interest rate swaps with the objective of limiting the variability of interest payment cash flows resulting from changes in the benchmark interest rate LIBOR. These interest rate swaps are designated as cash flow hedges involving the receipt of fixed-rate amounts from a counterparty in exchange for the Company making variable-rate payments over the life of the agreements without exchange of the underlying notional amount. The effective portion of changes in the fair value of the derivatives is recorded in accumulated other comprehensive income and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. Any ineffective portion of a financial instrument’s change in fair value is immediately recognized in earnings.

During the next twelve months, the Company estimates that an additional $0.4 million will be reclassified as a decrease to interest income from amounts reported in accumulated comprehensive income. During the six months endedJune 30, 2017, no derivative position designated as cash flow hedges were discontinued and none of the gains and losses reported in other comprehensive income were reclassified into earnings as a result of discontinuance of cash flow hedges.

During the second quarter of 2016, the company implemented an interest rate swap program to allow customers to convert variable rate loans to fixed rates. The interest rate swaps are simultaneously offset by interest rate swaps that the Company executes with its derivative counterparties. The changes in the fair value of the swaps offset each other, except for any differences in the credit risk of the counterparties. None of these interest rate swaps are designated or qualify as hedging relationships. As the interest rate swaps associated with this program do not meet hedge accounting requirements, changes in fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. The Company recorded $0.2 million of customer swap fees in non-interest income for the six months ended June 30, 2017.

The Company also enters into forward loan sales contracts, which are derived from loans held for sale, or in the Company’s pipeline, to enable those borrowers to manage their exposure to interest rate fluctuations. The forward loan sales derivative contracts are not designated as hedging instruments and all changes in fair value are recognized in non-interest income or non-interest expense during the period of change. For the six months endedJune 30, 2017, the Company recorded $29 thousand in non-interest income and $113 thousand in non-interest expense as a result of changes in fair value of derivatives. For the six months endedJune 30, 2016, the company recorded $57 thousand in non-interest income and $2 thousand in non-interest expense as a result of changes in fair value of derivatives.

The amount of collateral received and posted disclosed in the table above represents the offset of the assets and liabilities as of June 30, 2017. The actual cash collateral received and posted amounted to $0.3 million and $0.5 million, respectively.

The Company has agreements with certain of its derivative counterparties that contain a provision where if the Company defaults on any of its indebtedness or fails to maintain its status as a well-capitalized institution, then the Company could also be declared in default on its derivative obligations and could be required to terminate its derivative positions with the counterparty and settle the termination value of derivatives in a liability position.

As of June 30, 2017, there were eleven derivatives in a $2.0 million net liability position, which includes accrued interest and excludes nonperformance risk, related to these agreements. The Company is exposed to credit-related losses in the event of nonperformance by the counterparties to these agreements. The Company controls the credit risk of its financial contracts through credit approvals, limits and monitoring procedures and agreements that specify collateral levels to be maintained by the Company and the counterparties. The company has minimum collateral posting thresholds with certain derivative counterparties, and has posted $0.5 million of cash collateral against its obligations under these agreements as of June 30, 2017.

Overview

We are a bank holding company incorporated in late 2009 with the goal of creating a regional banking franchise in the southeastern region of the United States through organic growth and acquisitions of other banks, including failed, underperforming and undercapitalized banks. We have raised $955.6 million to make acquisitions through a series of private placements and an initial public offering of our common stock. Since inception, we have acquired eight depository institutions, including the assets and certain deposits from the Failed Banks. We operate 189 branches in Florida, North and South Carolina, Tennessee, and Virginia. During the six months endedJune 30, 2017, the Company closed and consolidated seven branches mostly related to the merger of CommunityOne. The Company expects to close and consolidate an additional elevenbranches during 2017. As such, the Company transferred $18.1 million from fixed assets to premises and equipment held for sale during the six months endedJune 30, 2017.

Results of Operations

Net Interest Income

Net interest income is the largest component of our income and is affected by the interest rate environment and the volume and composition of interest-earning assets and interest-bearing liabilities. Our interest-earning assets include loans, interest-

bearing deposits in other banks and investment securities. Other earning assets include Federal Home Loan Bank stock. Our interest-bearing liabilities include deposits, subordinated debentures, repurchase agreements and other short-term borrowings.

In the net interest margin and rate/volume analyses below, interest income and rates include the effects of a tax equivalent adjustments using applicable statutory tax rates in adjusting tax-exempt interest on tax-exempt investment securities and loans to a fully taxable basis. In the rate/volume analyses, average loan volumes include non-performing assets which results in the impact of the non-accrual of interest being reflected in the change in average rate. For each major category of interest-earning assets and interest-bearing liabilities, information is provided with respect to changes due to average volumes and changes due to rates, with the changes in both volumes and rates allocated to these two categories based on the proportionate absolute changes in each category.

Non-interest expense increased$32.2 million, or 35.2%, to $123.7 million for the six months endedJune 30, 2017 from $91.5 million for the six months endedJune 30, 2016. The increase was mainly driven by an increase of $14.5 million in salaries and employee benefits, $4.7 million in restructuring charges and $2.8 million in occupancy and equipment expenses, which were mostly related to the acquisition of CommunityOne.

Our efficiency ratios for the six months endedJune 30, 2017 and 2016 were 62.09% and 66.59%, respectively. Our core efficiency ratios for the six months endedJune 30, 2017 and 2016 were 57.63% and 60.34%, respectively.

The following table sets forth the components of non-interest expense for the periods indicated:

⁽¹⁾  Efficiency Ratio: Non-interest expense / (Non-interest income + Net interest income)

⁽²⁾  Core Efficiency Ratio: Core non-interest expense / (Core non-interest income + Net interest income)

The core efficiency ratio is a non-GAAP measure which we believe provides analysts and investors with information useful in understanding our business and evaluating our operating efficiency. We monitor the core efficiency ratio to evaluate and control operating costs. The core efficiency ratio is also a measure utilized by our Board of Directors in measuring management’s performance in controlling operating costs in comparison to peers. This non-GAAP measure has inherent limitations and is not required to be uniformly applied. It should not be considered in isolation or as a substitute for analysis of results reported under GAAP. This non-GAAP measure may not be comparable to similarly titled measures reported by other companies and should not be viewed as a substitute for non-interest expense.

Income Taxes

The provision for income taxes was $14.1 million and $25.1 million for the three and six months endedJune 30, 2017, respectively. The effective income tax rate was 37% and 36% for these periods, respectively.

At June 30, 2017 and December 31, 2016, the Company had no material amounts recorded for uncertain tax positions and no material unrecognized tax benefits. We do not expect to identify any material unrecognized tax benefits during the next 12 months.

Refer to Note 12. Income Taxes to our Consolidated Financial Statements for further information on our provision for income taxes.

Financial Condition

Our assets totaled $10.1 billion at June 30, 2017 and $9.9 billion at December 31, 2016. Total loans increased $163.9 million to $7.6 billion at June 30, 2017 compared to $7.4 billion at December 31, 2016. The increase in loans was due to new loan fundings of $986.6 million, partially offset by $62.1 million in resolutions of problem loans and $760.6 million in net principal repayments. Investment and trading securities increased by $200.4 million mainly due to $297.8 million of investment purchases and $8.1 million change in market valuation on available for sale investment securities, partially offset by $105.6 million of principal reductions and amortization, and $0.1 million in securities calls. Total deposits increased by $194.4 million or 2.5% to $8.1 billion at June 30, 2017 compared to $7.9 billion at December 31, 2016. Core deposits, which include all checking, savings and money market accounts, excluding brokered, increased by $38.0 million. Non-interest bearing checking accounts increased $72.3 million, interest bearing demand deposits decreased by $45.5 million, money market balances increased $27.8 million and savings deposits decreased by $16.6 million. Core deposits represent 70.7% and 72.0% of total deposits at June 30, 2017 and December 31, 2016, respectively. Brokered deposits and time deposits increased by $156.4 million. Borrowed funds, consisting of FHLB advances, short-term borrowings, notes payable and subordinated debentures, totaled $621.3 million and $681.3 million at

56

June 30, 2017 and December 31, 2016, respectively. FHLB advances decreased by $75.1 million to $470.6 million at June 30, 2017 compared to $545.7 million at December 31, 2016.

Shareholders’ equity was $1.3 billion at June 30, 2017 and December 31, 2016. The Company’s Board of Directors has authorized a stock repurchase plan of up to $400.0 million. Stock repurchases may be made from time to time, on the open market or in privately negotiated transactions. The approved stock repurchase program does not obligate the Company to repurchase any particular amount of shares, and the programs may be extended, modified, suspended, or discontinued at any time.

As of June 30, 2017, the Company has repurchased a total of $312.4 million, or 12,739,763 common shares at an average price of $24.52 per share, and had $87.6 million remaining under the current board authorized stock repurchase program.

Core return-on-assets (“core ROA”) is a non-GAAP measure which we believe provides management and investors with useful information to understand the effects of certain non-interest items and provides an alternative view of the Company’s performance over time and in comparison to the Company’s competitors. This non-GAAP measure has inherent limitations and is not required to be uniformly applied. It should not be considered in isolation or as a substitute for analysis of results reported under GAAP. This non-GAAP measure may not be comparable to similarly titled measures reported by other companies and should not be viewed as a substitute for results determined in accordance to GAAP.

During the six months endedJune 30, 2017, our loan portfolio increased by $163.9 million, as $986.6 million of loan fundings were partially offset by $62.1 million in resolutions of problem loans and $760.6 million in net principal repayments. Non-PCI loans represent 89.1% of our total loan portfolio as compared to 87.4% at December 31, 2016.

The composition of new loan production is indicative of our business strategy of emphasizing commercial and industrial and consumer loans. As illustrated in the table below, commercial loans and consumer and other loans represented approximately 27.3% and 31.3%, respectively, of new loan production for the six months endedJune 30, 2017. We expect that this production will be more balanced going forward, as we expect commercial real estate to comprise a larger proportion of new loan production.

The following table sets forth our new loans (excluding renewals of existing loans) segmented by loan type:

(Dollars in thousands)	Six Months Ended

We underwrite commercial real estate loans based on the value of the collateral, the ratio of debt service to property income and the creditworthiness of tenants. Due to the inherent risk of commercial real estate lending, we underwrite loans selectively. Accordingly, we have reduced the concentration in our portfolio over time, which had characterized our acquired loan portfolios.

59

Florida, North Carolina, South Carolina, and Tennessee accounted for 30.6%, 36.8%, 11.7% and 20.9% of our new loans, respectively, for the six months endedJune 30, 2017. Florida, North Carolina, South Carolina, and Tennessee accounted for 27.8%, 31.0%, 11.2% and 30.0% of our new loans, respectively, for the six months endedJune 30, 2016.

Asset Quality

Consistent with our strategy of operating with a sound risk profile, we focus on originating loans we believe to be of high quality, and disposing of non-performing assets rapidly and at reasonable valuations. To achieve these objectives, we underwrite new loans and manage existing loans in accordance with our underwriting standards under the direction of our Chief Credit Officer. Additionally, we have assigned senior credit officers to oversee the Florida, Tennessee and Carolinas markets, and we have established a special assets division to dispose of legacy problem loans and OREO.    

As of June 30, 2017, total loans were $7.6 billion, of which 0.2% were past due 30-89 days, 0.7% were nonperforming PCI (of which 0.1% were >90 days past due and still accreting) and 0.2% were nonaccrual. As of December 31, 2016, total loans were $7.4 billion, of which 0.3% were past due 30-89 days, 0.9% were nonperforming PCI (of which 0.2% were >90 days past due and still accreting) and 0.2% were nonaccrual.

At June 30, 2017, 10.9% of loans were acquired impaired loans. We applied acquisition accounting adjustments to the acquired loans to reflect estimates at the time of acquisition of the expected lifetime losses of such loans.

Total non-performing loans as of June 30, 2017declined by $6.9 million, or 9.2%, to $68.2 million as compared to $75.1 million at December 31, 2016. The change in non-performing loans during the six months endedJune 30, 2017 was attributable to $12.3 million in resolutions and $3.4 million in transfers to other real estate owned through foreclosures or receipt of deeds in lieu of foreclosures. Partially offsetting these decreases were $8.8 million of loans that became non-performing.

During the six months endedJune 30, 2017, of the loans we foreclosed, or received deeds in lieu of foreclosure, approximately $2.6 million consisted of residential loans and $0.8 million consisted of commercial real estate loans.

The customer-owed principal balances and carrying amounts as of June 30, 2017 and December 31, 2016 are set forth in the tables below:

Allowance and Provision for Loan and Lease Losses

At June 30, 2017, the allowance for loan and lease losses was $44.6 million, of which $24.0 million was associated with PCI loans and $20.6 million related to non-PCI loans. At June 30, 2017, the allowance for loan and lease losses represents 0.59% of our total $7.6 billion loan portfolio. At December 31, 2016, the allowance for loan and lease losses was $43.1 million, of which $23.0 million was associated with PCI loans and $20.1 million related to non-PCI loans. At December 31, 2016, the allowance for loan and lease losses represented 0.58% of our total $7.4 billion loan portfolio.

For non-PCI loans, the allowance for loan and lease losses reflects an allowance for probable incurred credit losses in the loan portfolio. Our formalized process for assessing the adequacy of the allowance for loan and lease losses and the resultant need, if any, for periodic provisions to the allowance charged to income, includes both individual loan analysis and loan pool analysis. Individual loan analysis are periodically performed on loan relationships of a significant size, or when otherwise deemed necessary, and are performed primarily on commercial real estate and other commercial loans. The result is that commercial real estate loans and commercial loans are divided into the following risk categories: Pass, Special Mention, Substandard and Doubtful. The allowance consists of specific and general components. When appropriate, a specific reserve will be established for individual loans based upon the risk classifications and the estimated potential for loss. The specific component relates to loans that are individually classified as impaired.

Home equity loans, indirect auto loans, residential loans and consumer loans generally are not analyzed individually or separately identified for impairment disclosures. These loans are grouped into pools and assigned risk categories based on their current payment status and management’s assessment of risk inherent in the various types of loans. The allocations are based on the same factors mentioned above. However, should such loans exceeding certain size thresholds exhibit signs of impairment, they may be individually evaluated for impairment.

For PCI loans, the allowance for loan and lease losses is a measure of impairment based upon our most recent estimates of expected cash flows. Our estimation of expected cash flows, which is used to determine the need for provisions to or reversals of the allowance every reporting period, is determined by assigning probability of default (“PD”) and loss given default (“LGD”) assumptions, amongst other assumptions such as prepayment speeds and recovery or liquidation timing. For commercial real estate and other commercial loans, we generally assign PD assumptions through the mapping of the following loan level risk ratings: Pass, Watch, Sub-Performing and Non-Performing. For home equity loans, residential loans, and consumer loans, PD is determined by mapping payment performance and delinquency status to market based default assumptions. Estimated loan to value ratios, determined using appraisals and/or real estate indices, are used to derive loss given default assumptions for real estate collateralized loans.

Senior management and our Board of Directors review this calculation and the underlying assumptions on a routine basis, not less frequently than quarterly.

The provision for loan and lease losses is a charge to income in the current period to establish or replenish the allowance and maintain it at a level that management has determined to be adequate to absorb estimated incurred losses in the loan portfolio for new loans. A provision for loan and lease losses is also required for any unfavorable changes in expected cash flows related to pools of purchased impaired loans. The provision for loan and lease losses and expectations of cash flows may be impacted by many factors, including changes in the value of real estate collateralizing loans, net charge-offs and credit losses incurred, changes in loans outstanding, changes in impaired loans, historical loss rates and the mix of loan types.

The provision for loan and lease losses in future periods for acquired loans will be most significantly influenced in the short term by the differences between the actual credit losses resulting from the resolution of problem loans and the estimated credit losses used in determining the estimated fair values of purchased impaired loans as of their acquisition dates. For new loans, the provision for loan and lease losses will be affected by the loss potential of impaired loans and trends in the delinquency of loans, non-performing loans and net charge offs, which cannot be reasonably predicted. Refer to Provision for loan and lease losses section for further discussion.

Management continuously monitors and actively manages the credit quality of the entire loan portfolio and will continue to recognize the provision required to maintain the allowance for loan and lease losses at an appropriate level.

The following table presents the roll-forward of the allowance for loan and lease losses for PCI and non-PCI loans for the three and six months endedJune 30, 2017 and 2016 by the class of loans against which the allowance is allocated:

No portion of the allowance allocated to non-PCI loans is in any way restricted to any individual loan or group of non-PCI loans, and the entirety of such allowance is available to absorb probable incurred credit losses from any and all such loans. The following table represents management’s best estimate of the allocation of the allowance for loan and lease losses for non-PCI loans to the various segments of the loan portfolio based on information available as of June 30, 2017 and December 31, 2016:

Criticized and Classified Loans

Loans with the following attributes are categorized as criticized and classified loans: (1) a potential weakness that deserves management’s close attention; (2) inadequate protection by the current net worth and paying capacity of the obligor or of the collateral pledged; or (3) weaknesses which make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

The following table summarizes criticized and classified loans at June 30, 2017 and December 31, 2016:

Total loans	$	193,193	$	232,177

⁽¹⁾  PCI and non-PCI loans are included in the balances presented.

Total criticized and classified loans declined$39.0 million, or 33.6% annualized, during the six months endedJune 30, 2017 as a result of $3.5 million in transfers to other real estate owned and $73.1 million of pay downs, charge offs and upgrades. Loan downgrades of $37.6 million partially offset the decline.

Impaired Loans

Non-performing loans and impaired loans are defined differently. Some loans may be included in both categories, whereas other loans may only be included in one category. A loan is considered impaired when it is probable that not all principal and interest amounts will be collected according to the loan contract. Generally, residential mortgages, commercial and commercial real estate loans exceeding certain size thresholds established by management are individually evaluated for impairment. Non-accrual loans and restructured loans where loan term concessions benefiting the borrowers have been made are generally designated as impaired.

Within the context of the accounting for impaired loans described in the preceding paragraph, other than the PCI loans described above, as of June 30, 2017, there were 157 loans individually evaluated for impairment and 90 deemed impaired with a related allowance for loan and lease losses of $674 thousand. At December 31, 2016, there were 137 loans individually evaluated for impairment and 83 deemed impaired with a related allowance for loan and lease losses of $274 thousand.

Due to the pool method of accounting for purchased credit impaired loans, non-performing PCI loans may be reported as 90 days past due and still accruing/accreting. Going forward, additional acquired loans not classified as purchased credit impaired and new loans originated by us may become impaired and will be classified as such. Impaired loans also include loans which were not classified as non-accrual, but otherwise meet the criteria for classification as an impaired loan (i.e., loans for which the collection of all principal and interest amounts as specified in the original loan contract are not expected, or where management has substantial doubt that the collection will be as specified, but is still expected to occur in its entirety). In our evaluation of the adequacy of the allowance for loan and lease losses, we consider (1) purchased credit impaired loans and loans classified as impaired, (2) our historical portfolio loss experience and trends as well as that of peers and (3) certain other quantitative and qualitative factors.

Non-Performing Assets

Non-performing assets include accruing/accreting loans delinquent 90 days or more, accreting PCI loans less than 90 days past due with expected cash flows less than contractual terms, non-accrual loans, repossessed personal property and other real estate. Non-PCI loans are placed on non-accrual status when management has concerns relating to the ability to collect the principal and interest and generally when such assets are 90 days past due. Non-performing assets were as follows:

At June 30, 2017 and December 31, 2016, loans classified as delinquent 90 days or more and accruing/accreting are entirely comprised of components of PCI loan pools. There were no non-PCI loans included in this category at the end of each period presented. In addition to the discussion in the previous section, please refer to Note 5. Loans in our Consolidated Financial Statements for a description of the accounting for pooled PCI loans.

Total non-performing assets at June 30, 2017declined by $18.9 million to $109.8 million compared to $128.8 million at December 31, 2016, which represents an annualized decline of 29.4%. The change in non-performing assets was attributable to the net decline in non-performing loans and other real estate owned of $6.9 million and $12.1 million, respectively. The net decline in non-performing loans was due to $12.3 million in resolutions and $3.4 million in transfers to other real estate owned through foreclosures or receipt of deeds in lieu of foreclosures, offset by $8.8 million of loans that became non-performing. The decline in other real estate owned was mainly due to sales of $15.1 million.

Investment Securities

Investment securities represent a significant portion of our assets. We invest in a variety of securities including obligations of U.S. government agencies, U.S. government-sponsored entities, including mortgage-backed securities, obligations of states or political subdivisions, privately issued mortgage-backed securities, bank eligible corporate obligations, mutual funds and limited types of equity securities.

Our investment activities are governed internally by a written, Board-approved policy. The investment policy is carried out by our Treasury department. Investment strategies are reviewed by the Risk Committee of the Board based on the interest rate environment, balance sheet mix, actual and anticipated loan demand, funding opportunities and our overall interest rate sensitivity. In general, the investment portfolio is managed in a manner appropriate to the attainment of the following goals: (1) to provide a margin of liquid assets sufficient to meet unanticipated deposit and loan fluctuations and overall funds management objectives; (2) to provide eligible securities to secure public funds and other borrowings; and (3) to manage interest rate risk and earn the maximum return on funds invested that is commensurate with meeting our first two goals.

Trading securities related to our non-qualified deferred compensation program and CRA investment fund totaled $4.3 million and $3.8 million at June 30, 2017 and December 31, 2016, respectively.

Our investment securities consisted primarily of U.S. agency mortgage-backed securities, which expose us to a low degree of credit and liquidity risk. The following tables set forth our investment securities as of June 30, 2017 and December 31, 2016:

We regularly review each investment security for impairment based on criteria that include the extent to which cost exceeds the estimated fair value, the financial health of and specific prospects for the issuer(s) and our ability and intention with regard to holding the security to maturity. Future declines in the fair value of securities may result in impairment charges which may be material to our financial condition and results of operations. More specifically, our impairment analysis is based on the following: (1) whether it is “more likely than not” we would have to sell a security prior to recovery of the amortized cost; (2) whether we

69

intend to sell the security; and (3) whether or not we expect to recover our recorded investment on an amortized cost basis based on credit characteristics of the investment. If, based upon our analysis, any of those conditions exist for a given security, we would generally be required to record an impairment charge in the amount of the difference between the carrying amounts and estimated fair value of such security. Based on our analysis there were no investment securities considered to be other-than-temporarily impaired at June 30, 2017 or December 31, 2016.

Deposits

Our strategy is to fund asset growth primarily with low-cost customer deposits in order to maintain a stable liquidity profile and net interest margin.

As of June 30, 2017, our core deposits, which we define as demand deposits, savings and money market accounts, excluding brokered, increased by $38.0 million as compared to December 31, 2016. The increase was mainly the result of the Company's continued focus on growing low-cost core deposits. The average contractual rate on core deposits increased to 0.23% at June 30, 2017, from 0.20% at December 31, 2016.

Time deposit balances increased by $81.1 million during the six months endedJune 30, 2017. At June 30, 2017, our wholesale time deposits increased by $20.3 million, while retail time deposits increased by $60.9 million as compared to December 31, 2016. The average contractual rate on time deposits increased to 1.02% from 0.93% at December 31, 2016. The weighted average

contractual rate of deposits increased to 0.47% from 0.41% for the periods ended June 30, 2017 and December 31, 2016, respectively.

The following table sets forth the balances and average contractual rates payable to customers on our deposits, segmented by account type as of June 30, 2017 and December 31, 2016:

Capital Resources and Liquidity

Capital Resources

In order to maintain a conservative risk profile, we operate with a prudent cushion of capital in relation to regulatory requirements and to the risk of our assets and business model. For planning purposes, we expect to operate with a minimum capital target equal to an 8% leverage ratio (defined as Tier 1 capital equal to 8% of average tangible assets), which would be in excess of regulatory standards for “well-capitalized” banks. We believe the 8% target is appropriate for our business model because of our conservative loan underwriting policies, investment portfolio composition, funding strategy, interest rate risk management limits and liquidity risk profile and because of the experience of our senior management team and Board of Directors.

Non-GAAP measures have inherent limitations and are not required to be uniformly applied. They should not be considered in isolation or as a substitute for analysis of results reported under GAAP. These non-GAAP measures may not be comparable to similarly titled measures reported by other companies and should not be viewed as a substitute for shareholders’ equity or total assets.

We calculate tangible book value, and tangible book value per share, which are non-GAAP measures because we believe they are useful for both investors and management as these are measures commonly used by financial institutions, regulators and investors to measure the capital adequacy of financial institutions. Tangible book value is equal to book value, or stockholders' equity, less goodwill and other intangible assets tax effected.

The following table sets forth a reconciliation of tangible book value and tangible book value per share to total shareholders’ equity, which is the most directly comparable GAAP measure:

The Company operates with a significant level of excess capital above regulatory requirements (see the table below for the historical capital ratios as well as minimum and well capitalized ratio requirements).

As of June 30, 2017, we had a Tier 1 leverage ratio of 11.8%, which provided us with $368.4 million in excess capital relative to our longer-term target of 8%. As of June 30, 2017, Capital Bank Corporation had a 10.7% Tier 1 leverage ratio, a 12.5% Tier 1 common capital ratio, a 12.5% Tier 1 risk-based ratio and a 13.1% Total risk-based capital ratio.

As of December 31, 2016, we had a Tier 1 leverage ratio of 12.2%, which provided us with $380.7 million in excess capital relative our longer-term planning target of 8%. As of December 31, 2016, Capital Bank Corporation had a 11.2% Tier 1 leverage ratio, a 12.4% Tier I common capital ratio, a 12.4% Tier 1 risk-based ratio and an 12.9% total risk-based capital ratio.

In July 2013, the U.S. banking regulators adopted a final rule which implements the Basel III regulatory capital reforms from the Basel Committee on Banking Supervision, and certain changes required by the Dodd-Frank Act. The final rule establishes an integrated regulatory capital framework and introduces the “Standardized Approach” for risk weighted assets, which replaces the Basel I risk-based guidance for determining risk-weighted assets as of January 1, 2015, the date we became subject to the new rules.

The rules include new risk-based capital and leverage ratios, which will be phased in from 2015 to 2019, and refine the definition of what constitutes “capital” for purposes of calculating those ratios. The new minimum capital level requirements applicable to the Company and the Bank under the final rules are as follows: (i) a new common equity Tier 1 capital ratio of 4.5%; (ii) a Tier 1 capital ratio of 6% (increased from 4%); (iii) a total capital ratio of 8% (unchanged from previous rules); and (iv) a Tier 1 leverage ratio of 4% for all institutions. The final rules also establish a “capital conservation buffer” above the new regulatory minimum capital requirements. The capital conservation buffer will be phased-in over four years beginning on January 1, 2016, as follows: the maximum buffer will be 0.625% of risk-weighted assets for 2016, 1.25% for 2017, 1.875% for 2018, and 2.5% for 2019 and thereafter. This will result in the following minimum ratios beginning in 2019: (i) a common equity Tier 1 capital ratio of 7.0%, (ii) a Tier 1 capital ratio of 8.5%, and (iii) a total capital ratio of 10.5%. Under the final rules, institutions are subject to limitations on paying dividends, engaging in share repurchases, and paying discretionary bonuses if its capital level

73

falls below the buffer amount. These limitations establish a maximum percentage of eligible retained income that could be utilized for such actions. As of June 30, 2017, our capital buffer would be 6.3%; well exceeding the 2.5% 2019 requirement.

The final rules also contain revisions to the prompt corrective action framework, which is designed to place restrictions on insured depository institutions if their capital levels begin to show signs of weakness. Under the prompt corrective action requirements, which are designed to complement the capital conservation buffer, insured depository institutions are now required to meet the following increased capital level requirements in order to qualify as “well capitalized:” (i) a new common equity Tier 1 capital ratio of 6.5%; (ii) a Tier 1 capital ratio of 8% (increased from 6%); (iii) a total capital ratio of 10% (unchanged from previous rules); and (iv) a Tier 1 leverage ratio of 5% (unchanged from previous rules).

Dividend Program

On July 20, 2017, the Company's board of directors approved a quarterly common dividend of $0.12 per share payable on August 21, 2017 to shareholders of record as of August 7, 2017.

Liquidity

Liquidity involves our ability to raise funds to support asset growth or reduce assets to meet deposit withdrawals and other funding needs, to maintain reserve requirements and to otherwise operate on an ongoing basis. To mitigate liquidity risk, our strategy is to fund asset growth primarily with low-cost customer deposits. We also operate under a liquidity policy and contingent liquidity plan that require us to monitor indicators of potential liquidity risk, utilize cash flow projection models to forecast liquidity needs, identify alternative back-up sources of liquidity and maintain a cushion of cash and liquid securities at 15% of total assets.

Our liquidity needs are met primarily by our cash position, growth in core deposits and cash flow from our amortizing investment and loan portfolios (including scheduled payments, prepayments, and maturities from portfolios of loans and investment securities). Our ability to borrow funds from non-deposit sources provides additional flexibility in meeting our liquidity needs. Short-term borrowings include federal funds purchased, securities sold under repurchase agreements and brokered deposits. We also utilize longer-term borrowings when management determines that the pricing and maturity options available through these sources create cost effective options for funding asset growth and satisfying capital needs. Our long-term borrowings include structured repurchase agreements and subordinated notes underlying our trust preferred securities.

As of June 30, 2017 and December 31, 2016, cash and liquid securities totaled 17.2% and 17.0% of assets, respectively, providing ample liquidity to support our existing bank franchise. As of June 30, 2017 and December 31, 2016, the ratio of wholesale to total funding was 14.3%, and 14.3%, respectively, which is below our policy limit of 25%. In addition to maintaining a stable core deposit base, we maintain adequate liquidity primarily through the use of investment securities, short term investments such as federal funds sold and unused borrowing capacity. We hold investments in FHLB stock for the purpose of maintaining credit lines with the FHLB. The credit availability is based on a percentage of the Bank’s total assets as reported in its most recent quarterly financial information submitted to the FHLB and subject to the pledging of sufficient collateral.

At June 30, 2017 and December 31, 2016, there were $470.6 million and $545.7 million, respectively, in FHLB advances outstanding. In addition, we had $15.3 million and $15.4 million in letters of credit outstanding as of June 30, 2017 and December 31, 2016, respectively. Collateral available under our agreements with the FHLB provided for incremental borrowing availability of up to approximately $482.6 million and $415.9 million, respectively.

We believe that we have adequate funding sources through unused borrowing capacity from the FHLB, unpledged investment securities, cash on hand and on deposit in other financial institutions, loan principal repayment and potential asset maturities and sales to meet our foreseeable liquidity requirements and contractual obligations.

ITEM 3: QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk Management

The Company pursues a conservative strategy with respect to interest rate risk management, with the goal of minimizing the risk that interest rate volatility will negatively impact our financial results. Due to the current low level of interest rates, we regard rising interest rates as the most likely source of risk and accordingly have sought to maintain an asset-sensitive position.

There are several components to our conservative interest rate strategy. First, we avoid holding loans with long duration. At June 30, 2017, approximately 53% of the loan portfolio was variable rate and of the remaining fixed rate loans, the vast majority had terms of less than five years. Second, the purpose of our securities portfolio is to provide liquidity and to manage interest rate sensitivity, and as such we limit its duration. At June 30, 2017, securities accounted for 16% of assets, and the effective duration of the portfolio was 3.6 years with limited extension risk to 4.3 years in a plus 300 basis point immediate parallel shift in interest rates. We utilize average life estimates based on prepayment rates obtained from an independent source. Third, we seek to fund the Bank, to the extent possible, with long-duration core deposits, and within core deposits, we emphasize checking account balances as the most stable and least risky source of funds. At June 30, 2017, core deposits accounted for 71% of total deposits, and checking balances accounted for 62% of core deposits.

We continuously monitor the Bank’s interest rate risk profile through our Asset Liability Committee, which consists of our Chief Executive Officer, Chief Financial Officer, Chief Credit Officer, Chief of Strategic Planning, Treasurer, business unit heads and certain other officers. To manage interest rate risk, our Board of Directors has established quantitative and qualitative guidelines with respect to our net interest income exposure and how predefined interest rate shocks affect our financial performance, measured in terms of forecast net interest income and economic value of equity, which is the intrinsic value of assets, less the intrinsic value of liabilities. Under our policy, these predefined rate shocks include minus 300, minus 200, minus 100, plus 100, plus 200 and plus 300 basis point immediate parallel shifts in interest rates.

If a predefined immediate parallel rate shock cannot be modeled due to the low level of interest rates, a proportional rate shock and policy limit applies and all other declining rate shocks will be suspended until such scenarios can be modeled. Because of the current low level of interest rates, the minus 200 and minus 300 rate shocks have been suspended. In addition to monitoring our compliance with these policies, management undertakes additional analysis, considering a wide range of possible interest rate fluctuations, including changes in the shape of the yield curve, and assessing the sensitivity of these results to key assumptions, including the behavior of depositors and loan customers.

Based upon the current interest rate environment, as of June 30, 2017, our sensitivity to interest rate risk was as follows:

(Dollars in thousands) Interest Rate Change in Basis Points	Next 12 Months Net Interest Income					Economic Value of Equity
	$ Change			% Change		$ Change			% Change
300	$	19,875		5.9	%	$	90,442		6.0	%
200	14,455			4.3	%	84,536			5.6	%
100	7,838			2.3	%	58,993			3.9	%
—	—			—	%	—			—	%
(100)	(14,341		)	(4.3	)%	(115,128		)	(7.6	)%

We used many assumptions to calculate the impact of changes in interest rates on our portfolio, and actual results may not be similar to projections due to several factors, including the timing and frequency of rate changes, market conditions and the shape of the yield curve. Actual results may also differ due to our actions, if any, in response to the changing rates. In calculating these exposures, we use an interest rate simulation model which is validated by third-party reviewers on an annual basis.

In the event the model indicates an unacceptable level of risk, we may take a number of actions to reduce this risk, including changing the terms, pricing, and conditions of new loans and deposits, the sale of a portion of our available-for-sale investment portfolio or the use of risk management strategies such as interest rate swaps and caps and cash flow hedges. As of June 30, 2017, we were in compliance with all of the limits and policies established by our Board of Directors in predefined plus rate shocks and remained temporarily out of compliance in the minus 100 basis point rate shocks primarily due to the low level of interest rates. We continuously evaluate all balance sheet strategies to optimize the Company’s interest rate risk position and will take prudent actions to maintain an appropriate interest rate risk position based on the level of interest rates and the policies established by our Board of Directors.

75

Inflation Risk Management

Inflation has an important impact on the growth of total assets in the banking industry and creates a need to increase equity capital to higher than normal levels in order to maintain an appropriate equity-to-assets ratio. We cope with the effects of inflation by managing our interest rate sensitivity position through our asset/liability management program, and by periodically adjusting our pricing of services and banking products to take into consideration current costs.

ITEM 4: CONTROLS AND PROCEDURES

(a) Evaluation of Disclosure Controls and Procedures

The Company’s Chief Executive Officer and Chief Financial Officer have evaluated the Company’s disclosure controls and procedures as of the end of the period covered by this report. Based upon that evaluation, they have concluded that the Company’s disclosure controls and procedures are effective in ensuring that information required to be disclosed is recorded, processed, summarized and reported within the time periods specified in the Commission’s rules and forms and are also designed to ensure that the information required to be disclosed in the reports filed or submitted under the Exchange Act is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosures.

(b) Internal Control Over Financial Reporting

Changes in internal control over financial reporting

There have been no changes in the Company’s internal control over financial reporting during the period ended June 30, 2017 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II OTHER INFORMATION

ITEM 1: LEGAL PROCEEDINGS

From time to time we are party to various litigation matters incidental to the conduct of our business. On July 14, 2017, a case captioned Robert Garfield v. First Horizon National Corporation, et al., Index No.CH-17-1022 (the “Garfield Action”), was filed on behalf of a putative class of First Horizon shareholders against First Horizon, its directors, and Capital Bank Financial Corp. in the Chancery Court of Shelby County, Tennessee, Thirtieth Judicial District, in connection with the merger. The complaint alleges, among other things, that the First Horizon director defendants breached their fiduciary duties by approving the merger, that Capital Bank Financial Corp. aided and abetted such breaches, and that First Horizon, its directors and Capital Bank Financial Corp. failed to disclose material information in connection with the merger. The complaint seeks, among other things, an order enjoining the merger, as well as other equitable relief and/or money damages, interest, costs, fees (including attorneys’ fees) and expenses. We believe that these claims are without merit.

On July 17, 2017, a case captioned Stephen Bushansky v. Capital Bank Financial Corp., et al., Case No. 3:17-cv-00422 (W.D.N.C.) (the “Bushansky Action”), was filed on behalf of a putative class of Capital Bank Financial Corp. shareholders against Capital Bank Financial Corp. and its directors in the United States District Court for the Western District of North Carolina in connection with the merger. The complaint alleges, among other things, that certain defendants violated Sections 14(a) and 20(a) of the Securities Exchange Act of 1934 by issuing a Registration/Joint Proxy Statement that, plaintiff alleges, is materially incomplete and misleading. On July 19, 2017, a case captioned Paul Parshall v. Capital Bank Financial Corp., et al., Case No. 3:17-cv-00428 (the “Parshall Action”) was filed in the United States District Court for the Western District of North Carolina on behalf of a putative class of Capital Bank Financial Corp. shareholders against Capital Bank Financial Corp., its directors, and First Horizon Corporation. On July 25, 2017, a case captioned Catherine McNamara vs. Capital Bank Financial Corp., et al., Case No. 3:17-CV-00439 (W.D.N.C.) (the “McNamara Action”) was filed on behalf of a putative class of Capital Bank Financial Corp. shareholders against Capital Bank Financial Corp. and its directors in the United States District Court for the Western District of North Carolina and its directors. The complaints in the Parshall Action and the McNamara Action, like the complaint in the Bushansky Action, alleges, among other things, that certain defendants violated Sections 14(a) and 20(a) of the Securities Exchange Act of 1934 by issuing a Registration/Joint Proxy Statement that, plaintiffs allege, is materially incomplete and misleading. The Bushansky, Parshall and McNamara Actions seek, among other things, an order enjoining the merger, as well as other equitable relief and/or money damages, interest, costs, fees (including attorneys’ fees) and expenses. We believe that the claims are without merit.

76

On April 1, 2016, the parties to the Consolidated WDNC Action filed with the Court a memorandum of understanding in which the parties agreed on the terms of a settlement of those lawsuits. In connection with the settlement, CommunityOne made certain supplemental disclosures related to the merger on April 6, 2016. Following the completion of confirmatory discovery, the parties to the Consolidated WDNC Action entered into a stipulation of settlement dated January 31, 2017. The stipulation of settlement in the Consolidated WDNC Action was submitted to the court for preliminary approval on February 17, 2017. On May 11, 2017, the Court entered an order which, among other things, preliminarily approved the proposed settlement, conditionally certified a settlement class, ordered that notice be mailed to the settlement class, and scheduled a settlement hearing to consider the fairness, reasonableness, and adequacy of the proposed settlement. If the proposed settlement is finally approved by the court, the settlement will resolve and release all claims in the Consolidated WDNC Action that were or could have been brought challenging any aspect of the proposed merger or the merger agreement and any disclosure made in connection therewith, pursuant to terms that will be disclosed to stockholders prior to final approval of the settlement. In addition, in connection with the proposed settlement, the parties contemplate that plaintiffs’ counsel will seek awards of attorneys’ fees and expenses. Capital Bank Financial will pay or cause to be paid those attorneys’ fees and expenses awarded by the court. There can be no assurance that the courts will approve the proposed settlement.

ITEM 1A: RISK FACTORS

There have been no material changes to the risk factors previously disclosed in the Company's Annual Report on Form 10-K for the year ended December 31, 2016 filed with the Securities and Exchange Commission.

Nature of Operations and Principles of Consolidation

Capital Bank Financial Corp. (“CBF” or the “Company”; formerly known as North American Financial Holdings, Inc.) is a bank holding company incorporated in late 2009 in Delaware and headquartered in North Carolina whose business is conducted primarily through Capital Bank Corporation (“Capital Bank Corporation” or the “Bank”). The Company was incorporated with the goal of creating a regional banking franchise in the southeastern region of the United States through organic growth and acquisitions of other banks, including failed, underperforming and undercapitalized banks. CBF has raised $955.6 million to make acquisitions through a series of private placements and an initial public offering of its common stock. Since inception, CBF has acquired eight depository institutions, including the assets and certain deposits from failed banks. CBF has a total of 189 full service banking offices located in Florida, North and South Carolina, Tennessee and Virginia. During the six months endedJune 30, 2017, the Company closed and consolidated seven branches in conjunction with the merger of CommunityOne. The Company expects to close and consolidate an additional elevenbranches during 2017. As such, the Company transferred $18.1 million from fixed assets to bank properties held for sale during the six months endedJune 30, 2017.

The accompanying unaudited Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and Regulation S-X. Accordingly, they do not include all of the information and disclosures required by U.S. GAAP for complete financial statement presentation. In the opinion of management, all adjustments consisting of normal recurring accruals and disclosures considered necessary for a fair interim presentation have been included. All significant inter-company accounts and transactions have been eliminated in consolidation. For further information, refer to the Company’s Consolidated Financial Statements and notes thereto included in the Company’s annual report on Form 10-K for the fiscal year ended December 31, 2016.

Proposed merger with First Horizon National Corporation

On May 4, 2017, Capital Bank Financial Corp. issued a press release announcing the execution of an agreement and plan of merger with First Horizon National Corporation (the “First Horizon”) dated May 3, 2017, with First Horizon as the surviving corporation. Subject to terms and conditions of the Merger Agreement, each holder of Capital Bank common stock will be entitled to receive cash or stock with a value equivalent to 1.750 First Horizon shares and $7.90 in cash for each Capital Bank share held, subject to the election allocation and proration provisions of the merger agreement. The transaction is subject to shareholder and regulatory approvals in addition to satisfying certain other closing conditions.

Use of Estimates and Assumptions

To prepare financial statements in conformity with U.S. GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as presented in the financial statements. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ.

Recent Accounting Pronouncements

In March 2017, the Financial Accounting Standard Board (the “FASB”) issued Accounting Standards Update ("ASU") 2017-09, "Compensation—Stock Compensation (Topic 718)". The amendments in this update provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. An entity should account for the effects of a modification unless all the following are met: (1) the fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the modified award is the same as the fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the original award immediately before the original award is modified. If the modification does not affect any of the inputs to the valuation technique that the entity uses to value the award, the entity is not required to estimate the value immediately before and after the modification, (2) the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified, (3) the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2017. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In March 2017, the FASB issued ASU 2017-08, "Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20) Premium Amortization on Purchased Callable Debt Securities". The amendments in this update affect all entities that have an amortized cost basis in excess of the amount that is repayable by the issuer at the earliest call date. The objective is to shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. Securities held at a discount continue to be amortized to maturity. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2018. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In March 2017, the FASB issued ASU 2017-07, "Compensation - Retirement Benefits (Topic 715)". The amendments in this update require that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost as defined in paragraphs 715-30-35-4 and 715-60-35-9 are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. If a separate line item or items are used to present the other components of net benefit cost, that line item or items must be appropriately described. If a separate line item or items are not used, the line item or items used in the income statement to present the other components of net benefit cost must be disclosed. The amendments in this update also allow only the service cost component to be eligible for capitalization when applicable (for example, as a cost of internally manufactured inventory or a self-constructed asset). The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2017. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In January 2017, the FASB issued ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350)". The amendments in this update aim to simplify the subsequent measurement of goodwill. Under these amendments, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. The FASB also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment. An entity is required to disclose the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets and still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2019. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In January 2017, the FASB issued ASU 2017-01, "Business Combinations (Topic 805)". The amendments in this update provide a screen to determine when a set is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The amendments in this update should be applied prospectively on or after the effective date. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In May 2016, the FASB issued ASU 2016-12, "Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients". The amendments in this Update represent minor corrections or improvements to narrow aspects of Topic 606, as amended by ASU No. 2014-09, and do not change the core principle of the guidance in Topic 606. The effective date and transition requirements for the amendments in this Update are the same as the effective date and transition requirements for Topic 606 (and any other Topic amended by Update 2014-09), which is not yet effective. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows—Credit Losses (Topic 230)". The amendments in this update provide guidance on the following eight specific cash flow issues: (1) Debt prepayment or debt extinguishment costs; (2) Settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; (3) Contingent consideration payments made after a business combination; (4) Proceeds from the settlement of insurance claims; (5) Proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; (6) Distributions received from equity method investees; (7) Beneficial interests in securitization transactions; (8) Separately identifiable cash flows and application of the predominance principle. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments—Credit Losses (Topic 326)". The main objective of this update is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates and affects loans, debt securities, trade receivables, net investments in leases, off-balance-sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. For public business entities that are U.S. Securities and Exchange Commission (SEC) filers, the amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In March 2016, the FASB issued ASU 2016-9, "Compensation—Stock compensation (Topic 718)". Improvements to employee share-based payment accounting" which objective is the simplification through the identification, evaluation, and improvement of areas of generally accepted accounting principles (GAAP) for which cost and complexity can be reduced while maintaining or improving the usefulness of the information provided to users of financial statements. The areas for simplification involve several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Some of the areas for simplification apply only to nonpublic entities. We early adopted ASU 2016-09 during the fourth quarter of 2016 and prior periods were modified retrospectively. The adoption did not have a material impact on the Company's consolidated financial statements. The impact resulted in, among other items, a $0.1 million increase to net income and a $0.01 increase to earnings per share for the six months endedJune 30, 2016. The Company reflected these adjustments in our disclosures including the consolidated financial statements, earnings per common share, business combination and acquisitions, stock-based compensation, and income taxes.

In March 2016, the FASB issued ASU No. 2016-08, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net)”. The amendments in this update will clarify the implementation guidance on principal versus agent considerations. Topic 606 requires an entity to determine whether the nature of its promise is to provide that good or service to the customer (that is, the entity is a principal) or to arrange for the good or service to be provided to the customer by the other party (that is, the entity is an agent). This determination is based upon whether the entity controls the good or the service before it is transferred to the customer. Topic 606 includes indicators to assist in this evaluation. The effective date and transition requirements for the amendments in this update are the same as the effective date and transition requirements for Topic 606 (and any other Topic amended by update 2014-09 listed below), which is not yet effective. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In March 2016, the FASB issued ASU 2016-7, "Investments—Equity Method and Joint Ventures (Topic 323)". The amendments in this update eliminate the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments in this update require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The amendments in this update are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The amendments should be applied prospectively upon their effective date to increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. Earlier application is permitted. The adoption did not have a material impact on the Company's consolidated financial statements.

In March 2016, the FASB issued ASU 2016-6, "Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments". The amendments in this update clarify the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments in this update is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. For public business entities, the amendments in this update are effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The adoption did not have a material impact on the Company's consolidated financial statements.

In January 2016, the FASB issued ASU 2016-2, "Leases (Topic 842)" which increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. To meet that objective, the FASB is amending the FASB Accounting Standards Codification and creating Topic 842, Leases. This update, along with IFRS 16, Leases, are the results of the FASB’s and the International Accounting Standards Board’s (IASB’s) efforts to meet that objective and improve financial reporting. The FASB and IASB decided to not fundamentally change lessor accounting with the amendments in this update. However, some changes have been made to lessor accounting to conform and align that guidance with the lessee guidance and other areas within generally accepted accounting principles (GAAP), such as Topic 606, Revenue from Contracts with Customers. The main difference between previous GAAP and Topic 842 is the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. For public business entities, the amendments in ASU 2016-2 are effective for fiscal years beginning after December 15, 2018. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In January 2016, the FASB issued ASU 2016-1, "Financial instruments—Overall (Subtopic 825-10)" which requires all equity investments to be measured at fair value with changes in the fair value recognized through net income (other than those accounted for under equity method of accounting or those that result in consolidation of the investee). The amendments in this update also require an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. In addition, the amendments in this update eliminate the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities and the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet for public business entities. For public business entities, the amendments in ASU 2016-1 are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of ASU 2016-1 is not expected to have a material impact on the Company's consolidated financial position, results of operations and cash flows.

In May 2014, the FASB issued ASU 2014-9, "Revenue from Contracts with Customers (Topic 606)". The core principle of Topic 606 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies the performance obligation. In August 2015, the FASB issued ASU 2015-14, "Revenue from contracts with customers (Topic 606) - Deferral of the Effective Date". The amendments in ASU 2015-14 establish December 15, 2017 as the effective date of the information related to ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)”. While we anticipate some changes, the Company does not expect a material change from our current accounting for revenue as the majority of our interest and non-interest income is not in scope of Topic 606.

Earnings Per Share [Abstract]

Earnings Per Common Share

Earnings Per Common Share

Basic earnings per share is computed as net income attributable to common shareholders divided by the weighted average number of common shares outstanding during the period. Diluted earnings per share include the dilutive effect of additional potential common shares issuable under stock options and unvested restricted shares computed using the treasury stock method. Earnings per share have been computed based on the following:

(Shares in thousands)	Three Months Ended		Six Months Ended
	June 30, 2017	June 30, 2016	June 30, 2017	June 30, 2016
Weighted average number of shares outstanding:

Dilutive effect of unvested restricted shares	65	16	54	8
Diluted	53,226	44,068	53,214	44,074

The dilutive effect of stock options and unvested restricted shares are the only common stock equivalents for purposes of calculating diluted earnings per common share.

Weighted average anti-dilutive stock options and unvested restricted shares excluded from the computation of diluted earnings per share are as follows:

Business Combinations and Acquisitions

Acquisition of CommunityOne Bancorp

On October 26, 2016, the Company completed its acquisition of CommunityOne Bancorp (“CommunityOne”) whereby CommunityOne merged with and into the Company. CommunityOne was a North Carolina-based bank with $2.4 billion in assets and 45 full service banking branches as of October 26, 2016. The combination will strengthen Capital Bank’s franchise in North Carolina, particularly in Charlotte, as well as in Greensboro/Winston Salem and the Catawba/Caldwell county area.

The Company acquired 100% of the outstanding common stock of CommunityOne. The total purchase price for CommunityOne was $340.5 million, consisting of $51.9 million of cash, and the issuance of 8.9 million shares of Capital Bank Common Stock valued at $288.6 million based on the Company's stock on October 25, 2016.

The acquisition was accounted for under the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations. Accordingly, the Company recognizes amounts for identifiable assets acquired and liabilities assumed at their estimated acquisition date fair value, with any excess of purchase consideration over the net assets being reported as goodwill. As the fair value of consideration paid exceeded the estimated fair value of net assets acquired, nondeductible goodwill of $103.4 million was recorded. Fair value estimates are based on the information available, and are subject to change for up to one year after the closing date of the acquisition as additional information relative to the closing date fair values becomes available. During the three months endedJune 30, 2017, there were no changes to the acquisition date balance sheet. During the six months endedJune 30, 2017, the Company adjusted the acquisition date balance sheet to reflect (1) a $0.4 million increase due to a recovery on a fully charged off loan; (2) a $1.0 million increase in the deferred tax asset; and (3) a $1.3 million decrease in Goodwill caused by the net effect of these adjustments. These adjustments are reflected in the table below. Management continues to review initial estimates on certain areas such as loan valuations, core deposit intangibles and the deferred tax asset.

The following table summarizes the Company's investment and CommunityOne's opening balance sheet as of October 26, 2016 adjusted to their preliminary fair value:

The following table summarizes the fair value of loans, the total contractual principal and interest payments, and management's estimate of expected total cash payments of purchase credit impaired loans:

(Dollars in thousands)	Fair Value of Acquired Loans		Gross Contractual Amounts Receivable		Best Estimate of Contractual Cash Flows not to be Collected
Loans acquired subject to ASC 310-30	$	129,075	$	182,927	$	34,219

In addition, the Bank acquired loans of $1.4 billion not determined to be purchase credit impaired at the time of acquisition. These loans have an estimated cash flow of $1.6 billion and management expects to collect contractual required payments from the borrower with similar characteristics as other non-impaired loans.

In the assumption of deposit liabilities, the Company estimated the fair value of the core deposits intangible asset to be $19.9 million, which will be amortized utilizing an accelerated amortization method over an estimated economic life of 10 years. Fair value estimates are based on factors such as type of deposit, retention rates, interest rates and customer relationships.

As of June 30, 2017, the Company’s security portfolio consisted of 175 securities, 75 of which were in an unrealized loss position. The majority of unrealized losses are related to the Company’s mortgage-backed securities.

The corporate bonds in an unrealized loss position at June 30, 2017 and December 31, 2016 continue to perform and are expected to perform through maturity. Unrealized losses associated with these securities are primarily due to changes in interest rates and market volatility, and the corporate issuers have not experienced significant adverse events that would call into question their ability to repay those debt obligations according to contractual terms. Further, because the Company does not have the intent to sell these corporate bonds and it is more likely than not that it will not be required to sell the securities before their anticipated recovery of their amortized cost bases, the Company does not consider these securities to be other-than-temporarily impaired as of June 30, 2017 or December 31, 2016.

All of the mortgage-backed securities at June 30, 2017 and December 31, 2016 were issued by U.S. government-sponsored entities and agencies, which the government has affirmed its commitment to support. Unrealized losses associated with these securities are attributable to changes in interest rates and illiquidity, and not credit quality, and because the Company does not have the intent to sell these mortgage-backed securities and it is more likely than not that it will not be required to sell the securities before their anticipated recovery, the Company does not consider these securities to be other-than-temporarily impaired at June 30, 2017 or December 31, 2016.

Investment securities having carrying values of approximately $650.8 million and $621.8 million at June 30, 2017 and December 31, 2016, respectively, were pledged to secure public funds on deposit, securities sold under agreements to repurchase, and for other purposes as required by law.

Total loans include $3.5 million and $12.9 million of loans held for sale and $15.0 million and $15.5 million of net deferred loan origination costs and fees as of June 30, 2017 and December 31, 2016, respectively.

As of June 30, 2017, other loans include $42.9 million, $155.3 million and $1.3 million of farm land, state and political subdivision obligations and deposit customer overdrafts, respectively. As of December 31, 2016, other loans include $41.9 million, $149.0 million and $1.6 million of farm land, state and political subdivision obligations and deposit customer overdrafts, respectively.

The Company designates purchased credit impaired loans as "PCI" by evaluating both qualitative and quantitative factors. At the time of acquisition, the Company accounted for the PCI loans by segregating each portfolio into loan pools with similar risk characteristics. Over the lives of the acquired PCI loans, the Company continues to estimate cash flows expected to be collected on each loan pool. The Company evaluates, at each balance sheet date, whether its estimates of the present value of the cash flows from the loan pools, determined using the effective interest rates, has decreased, such that the present value of such cash flows is less than the recorded investment of the pool, and if so, recognizes a provision for loan loss in its Consolidated Statements of Income, unless related to non-credit events.

Additionally, if the Company has favorable changes in estimates of cash flows expected to be collected for a loan pool such that the then-present value exceeds the recorded investment of that pool, the Company will first reverse any previously established allowance for loan and lease losses for the pool. If such estimate exceeds the amount of any previously established allowance, the Company will accrete future interest income over the remaining life of the pool at a rate which, when used to discount the expected cash flows, results in the then-present value of such cash flows equaling the recorded investment of the pool at the time of the revised estimate.

The table below presents a roll forward of accretable yield and income expected to be earned related to PCI loans. The accretable yield represents the excess of estimated cash flows expected to be collected over the carrying amount of the PCI loans. Nonaccretable difference represents estimated contractually required payments in excess of estimated cash flows expected to be collected. Other represents reductions of accretable yield due to non-credit events such as prepayment activity on PCI loans.

The accretable yield is accreted into interest income over the estimated life of the PCI loans using the level yield method. The accretable yield will change due to changes in:

• The estimate of the remaining life of PCI loans which may change the amount of future interest income, and possibly principal, expected to be collected;

• The estimate of the amount of contractually required principal and interest payments over the estimated life that will not be collected (the nonaccretable difference); and

• Indices for PCI loans with variable rates of interest.

For PCI loans, the impact of loan modifications is included in the evaluation of expected cash flows for subsequent decreases or increases of cash flows. For variable rate PCI loans, expected future cash flows will be recalculated as the rates adjust over the lives of the loans. At acquisition, the expected future cash flows were based on the variable rates that were in effect at that time.

The following is a summary of the major categories of loans outstanding as of June 30, 2017 and December 31, 2016:

(1)Pooled PCI loans are not classified as nonaccrual as they are considered to be accruing because their interest income relates to the accretable yield recognized under accounting for purchased credit-impaired loans and not to contractual interest payments.

Credit Quality Indicators

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans as to credit risk. This analysis is performed at origination and upon identification of a material change for all loans, on an annual basis for commercial loans exceeding $0.5 million, and at least quarterly for commercial loans not rated pass. The Company uses the following definitions for risk ratings:

• Pass —These loans range from superior quality with minimal credit risk to loans requiring heightened management attention but that are still an acceptable risk and continue to perform as contracted.

• Special Mention —Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date.

• Substandard —Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.

• Doubtful —Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

The following table summarizes loans, excluding PCI loans, by internal rating at June 30, 2017:

Troubled Debt Restructuring

If a borrower is experiencing financial difficulty, the Bank may consider, in certain circumstances, modifying the terms of their loan to maximize collection of amounts due. A troubled debt restructuring (“TDR”) typically involves either a reduction of the stated interest rate of the loan, an extension of the loan’s maturity date(s) with a stated rate lower than the current market rate for a new loan with similar risk, or in limited circumstances, a reduction of the principal balance of the loan or the loan’s accrued interest. Upon modification of a loan, the Bank measures the related impairment as the excess of the recorded investment in the loan over the discounted expected future cash flows. The present value of expected future cash flows is discounted at the loan’s effective interest rate. If the impairment analysis results in a loss, an allowance for loan and lease losses is established for the loan. During the six months endedJune 30, 2017 and 2016, loans modified in TDRs were nominal. Because of the insignificance of the amount and the nature of the modifications, the modifications did not have a material impact on the Company’s Consolidated Financial Statements or on the determination of the allowance for loan and lease losses at June 30, 2017 and 2016. The Company had loans modified in TDRs with recorded investments of $2.5 million, $2.7 million, and $1.8 million as of June 30, 2017, December 31, 2016 and June 30, 2016, respectively.

Federal Home Loan Bank Advances and Short-Term Borrowings

Federal Home Loan Bank Advances and Short-Term Borrowings

Short-term borrowings include securities sold under agreements to repurchase, cash received from counterparties as collateral for mark-to-market exposure on interest rate swaps, and advances from the Federal Home Loan Bank (“FHLB”) .

The Bank has securities sold under agreements to repurchase with customers. These overnight agreements are collateralized by investment securities of the United States Government or its agencies which are chosen by the Bank. The amounts outstanding at June 30, 2017 and December 31, 2016 were $32.4 million and $18.0 million, respectively, and were collateralized by $37.7 million and $27.6 million, respectively, of agency mortgage-backed securities.

The Bank has $0.3 million and $1.2 million of short term borrowings related to cash received from counterparties as collateral for mark-to-market exposure on interest rate swaps at June 30, 2017 and December 31, 2016, respectively.

The Bank invests in FHLB stock for the purpose of establishing credit lines with the FHLB. The credit availability to the Bank is based on a percentage of the Bank’s total assets as reported on the most recent quarterly financial information submitted to the regulators subject to the pledging of sufficient collateral. The Bank’s collateral with the FHLB consists of a blanket floating lien pledge of the Bank’s residential 1-4 family mortgage, multifamily, home equity line of credit and commercial real estate secured loans. The amounts of eligible collateral at June 30, 2017 and December 31, 2016 provided for incremental borrowing availability of up to $482.6 million and $415.9 million, respectively.

At June 30, 2017 and December 31, 2016, the Bank had $15.3 million and $15.4 million in letters of credit issued by the FHLB respectively, of which $15.0 million and $15.2 million are used as collateral for public funds deposits in lieu of pledging securities to the State of Florida, respectively.

The FHLB advances as of June 30, 2017 and December 31, 2016 consisted of the following:

Subordinated Debentures

Through its acquisitions of TIB Financial ("TIBB"), Capital Bank Corp. ("CBKN"), Green Bankshares ("GRNB"), Southern Community Financial ("SCMF" or "Southern Community"), and CommunityOne Bancorp ("COB" or "CommunityOne"), the Company assumed fourteen separate pooled offerings of trust preferred securities listed below. The Company is not considered the primary beneficiary of the trusts (variable interest entities), therefore the trusts are not consolidated in the Company’s Consolidated Financial Statements, but rather the subordinated debentures are presented as liabilities. The trusts consist of wholly-owned statutory trust subsidiaries for the purpose of issuing the trust preferred securities. The trusts used the proceeds from the issuance of trust preferred securities to acquire junior subordinated deferrable interest debentures of the Company. The trust preferred securities essentially mirror the debt securities, carrying a cumulative preferred dividend equal to the interest rate on the debt securities. The debt securities and the trust preferred securities each have 30-year lives. The trust preferred securities and the debt securities are callable by the Company or the trust, at their respective option after a period of time, and at varying premiums and sooner in specific events, subject to prior approval by the Federal Reserve Board (“FRB”), if then required. Deferral of interest payments on the trust preferred securities is allowed for up to 60 months without being considered an event of default.

The subordinated debentures are included in Tier 1 capital under the capital guidelines of the Dodd-Frank Act. The subordinated debentures as of June 30, 2017 and December 31, 2016 consisted of the following:

Regulatory Capital Requirements [Abstract]

Shareholders' Equity and Minimum Regulatory Capital Requirements

Shareholders’ Equity and Minimum Regulatory Capital Requirements

The Company (on a consolidated basis) and the Bank are subject to various regulatory capital requirements administered by federal and state banking agencies. Failure to meet minimum capital requirements results in certain discretionary and required actions by regulators that could have an effect on the Company’s operations. The regulations require the Company and the Bank to meet specific capital adequacy guidelines that involve quantitative measures of assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The Company’s capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.

To be considered well capitalized or adequately capitalized as defined under the regulatory framework for prompt corrective action, the Bank must maintain minimum Tier 1 leverage, Tier 1 common, Tier 1 risk-based and Total Risk-based ratios. At June 30, 2017 and December 31, 2016 the Bank maintained capital ratios exceeding the requirement to be considered well capitalized. These minimum ratios along with the actual ratios for the Company and the Bank are presented in the following tables:

As of June 30, 2017 and December 31, 2016, the Company and the Bank met all capital requirements to which they were subject. Tier 1 Capital for the Company includes trust preferred securities to the extent allowable.

Dividends that may be paid by a national bank are limited to that bank’s retained net profits for the preceding two years plus retained net profits up to the date of any dividend declaration in the current calendar year. The Company received dividends from the Bank totaling $6.8 million, $4.2 million, $6.1 million, $5.7 million, and $64.2 million, on May 2, 2017, January 31, 2017, January 24, 2017, October 19, 2016 and June 1, 2016, respectively. The Company may use these dividends for general corporate purposes including acquisitions, or as a return of capital to shareholders through future share repurchases or dividends.

In July 2013, the U.S. banking regulators adopted a final rule which implements the Basel III regulatory capital reforms from the Basel Committee on Banking Supervision, and certain changes required by the Dodd-Frank Act. The final rule established an integrated regulatory capital framework and introduces the “Standardized Approach” for risk-weighted assets, which replaces the Basel I risk-based guidance for determining risk-weighted assets as of January 1, 2015, the date the Company became subject to the new rules. Based on the Company's current capital composition and levels, the Company believes it is in compliance with the requirements as set forth in the final rules.

The rules include new risk-based capital and leverage ratios, which will be phased in from 2015 to 2019, and refine the definition of what constitutes “capital” for purposes of calculating those ratios. The new minimum capital level requirements applicable to the Company and the Bank under the final rules are as follows: (i) a new common equity Tier 1 capital ratio of 4.5%; (ii) a Tier 1 capital ratio of 6% (increased from 4%); (iii) a total capital ratio of 8% (unchanged from previous rules); and (iv) a Tier 1 leverage ratio of 4% for all institutions. The final rules also establish a “capital conservation buffer” above the new regulatory minimum capital requirements. The capital conservation buffer will be phased-in over four years beginning on January 1, 2016, as follows: the maximum buffer will be 0.625% of risk-weighted assets for 2016, 1.25% for 2017, 1.875% for 2018, and 2.5% for 2019 and thereafter. This will result in the following minimum ratios beginning in 2019: (i) a common equity Tier 1 capital ratio of 7.0%, (ii) a Tier 1 capital ratio of 8.5%, and (iii) a total capital ratio of 10.5%. Under the final rules, institutions are subject to limitations on paying dividends, engaging in share repurchases, and paying discretionary bonuses if its capital level falls below the buffer amount. These limitations establish a maximum percentage of eligible retained income that could be utilized for such actions. As of June 30, 2017, our capital buffer is 6.3%; exceeding the 2.5% 2019 requirement.

The final rules also contain revisions to the prompt corrective action framework, which is designed to place restrictions on insured depository institutions if their capital levels begin to show signs of weakness. Under the prompt corrective action requirements, which are designed to complement the capital conservation buffer, insured depository institutions are required to meet the following increased capital level requirements in order to qualify as “well capitalized:” (i) a new common equity Tier 1 capital ratio of 6.5%; (ii) a Tier 1 capital ratio of 8% (increased from 6%); (iii) a total capital ratio of 10% (unchanged from previous rules); and (iv) a Tier 1 leverage ratio of 5% (unchanged from previous rules).

Dividend Program

On July 20, 2017, the Company's board of directors approved a quarterly common dividend of $0.12 per share payable on August 21, 2017, to shareholders of record as of August 7, 2017.

Share Repurchases

The Company’s board of directors has authorized stock repurchases of up to $400.0 million. Stock repurchases may be made from time to time, on the open market or in privately negotiated transactions. The approved stock repurchase program does not obligate the Company to repurchase any particular amount of shares, and the program may be extended, modified, suspended, or discontinued at any time.

As of June 30, 2017, the Company has repurchased a total of $312.4 million, or 12,739,763 common shares at an average price of $24.52 per share with $87.6 million remaining under the current board authorized stock repurchase program.

The Company accounts for treasury stock using the cost method as a reduction of shareholders’ equity in the accompanying Consolidated Balance Sheets and Statements of Changes in Shareholders’ Equity.

Stock-Based Compensation

Stock-Based Compensation

As of June 30, 2017, the Company had two compensation plans, the 2010 Equity Incentive Plan (the "2010 Plan") and the 2013 Omnibus Compensation Plan (the “2013 Plan”) under which shares of its common stock are issuable in the form of stock options, stock appreciation rights, restricted stock, restricted stock units, stock awards, stock bonus awards, and other incentive awards. The 2010 Plan was replaced by the 2013 Plan and no further awards may be made pursuant to the 2010 Plan.

The 2013 Plan was effective May 22, 2013 and expires on May 22, 2023, the tenth anniversary of the effective date. The maximum number of shares of common stock of the Company that may be optioned or awarded under this plan is 2,639,000 shares. Awards under this plan may be made to any person selected by the Compensation Committee.

The following table summarizes the components and classification of stock-based compensation expense for the three and six months endedJune 30, 2017 and 2016:

(Dollars in thousands)	Three Months Ended				Six Months Ended
	June 30, 2017		June 30, 2016		June 30, 2017		June 30, 2016
Stock options	$	28	$	12	$	52	$	21
Restricted stock	936		455		1,812		763
Total stock-based compensation expense	$	964	$	467	$	1,864	$	784

The tax benefit related to stock-based compensation expense arising from restricted stock awards and non-qualified stock options was $362 thousand and $177 thousand for the three months endedJune 30, 2017 and 2016, respectively and $699 thousand and $298 thousand for the six months endedJune 30, 2017 and 2016, respectively.

Stock Options

Under the 2010 Plan and 2013 Plan, the exercise price for common stock must equal at least 100% of the fair market value of the stock on the day an option is granted. The exercise price under an incentive stock option granted to a person owning stock representing more than 10% of the common stock must equal at least 110% of the fair market value at the date of grant, and such option is not exercisable after five years from the date the incentive stock option was granted. The Board of Directors may, at its discretion, provide that an option not be exercised in whole or in part for any period or periods of time as specified in the option agreements. Stock options have an expiration of ten years from the date it is granted. Under these plans, 83,729 options were exercised and 15,623 stock options were granted during the six months endedJune 30, 2017.

The fair value of each option is estimated as of the date of the grant using the Black-Scholes Option Pricing Model. This model requires the input of subjective assumptions that will usually have a significant impact on the fair value estimate. The dividend yield assumption is consistent with management expectations of dividend distributions based upon the Company’s business plan at the date of grant. The risk-free interest rate was developed using the U.S. Treasury yield curve for a period equal to the expected life of the options on the grant date. The expected option life for the current period grants was estimated using the vesting period, the term of the option and estimates of future exercise behavior patterns. The expected volatility assumption was based on the historical volatility of the Company's stock price.

ASC 718 requires the recognition of stock-based compensation expense for the number of awards that are ultimately expected to vest. During the six months endedJune 30, 2017 and 2016, stock based compensation expense was recorded based upon assumptions that the Company would experience no forfeitures. This assumption of forfeitures will be reassessed in subsequent periods based on historical forfeiture rates and may change based on new facts and circumstances. Any changes in assumptions will be accounted for prospectively in the period of change.

A summary of the stock option activity for the six months endedJune 30, 2017 and 2016 is as follows:

	Six Months Ended
	June 30, 2017				June 30, 2016
(Shares in thousands)	Shares		Weighted     Average Exercise Price Per Share		Shares		Weighted     Average Exercise Price  Per Share

Balance, June 30,	3,108		$	20.92	3,076		$	20.23

At June 30, 2017, the weighted average remaining contractual life for outstanding stock options was approximately 3.34 years and the aggregate intrinsic values was $51.5 million for stock options outstanding and exercisable.

The intrinsic value for stock options is calculated as the difference between the exercise price of the underlying awards and the market price of the Company’s common stock as of the reporting date.

Options outstanding at June 30, 2017 were as follows:

(Shares in thousands)	Outstanding Options				Exercisable Options
Range of Exercise Prices	Shares	Weighted Average Remaining Contractual Life	Weighted Average Exercise Price Per Share		Shares	Weighted Average Exercise Price Per Share
$18.00	121	5.89 years	$	18.00	121	$	18.00

$18.00 - $2,026.00	3,108	3.34 years	$	20.85	3,053	$	20.59

Restricted Stock

Restricted stock provides the grantee with voting, dividend and anti-dilution rights equivalent to common shareholders, but is restricted from transfer until vested, at which time all restrictions are removed. The restricted stock vests ratably over a three-year period subject to continued employment with the company. The value of the restricted stock is being amortized on a straight-line basis over the implied service periods. There were 165,063 restricted stock awards granted under the 2013 Plan during the six months endedJune 30, 2017.

The following table summarizes unvested restricted stock activity for the six months endedJune 30, 2017 and 2016:

The Company uses an estimated annual effective tax rate method of computing its interim tax provision. The effective tax rate is based on forecasted annual pre-tax income, permanent differences and statutory tax rates. For the three and six months endedJune 30, 2017, the effective income tax rates were 37% and 36%, respectively. For the three and six months endedJune 30, 2016, the effective income tax rates were 37%. The change in effective income tax rate was mainly due to higher state income taxes, higher tax exempt interest income and other favorable adjustments.

The Company and its subsidiaries are subject to U.S. federal income tax, as well as income tax of the states of Florida, New York, South Carolina, North Carolina, and Tennessee. The net deferred tax assets as of June 30, 2017 and December 31, 2016 were $134.5 million and $150.3 million, respectively. A valuation allowance related to deferred tax assets is required when it is considered more likely than not that all or part of the benefit related to such assets will not be realized. In assessing the need for a valuation allowance, the Company considered both positive and negative evidence in concluding that no valuation allowance was necessary at June 30, 2017 and December 31, 2016.

At June 30, 2017 and December 31, 2016, the Company had $464.6 million and $478.6 million of gross federal net operating loss carry-forwards, respectively, which begin to expire after 2028 and are subject to annual cumulative limitation of $27.8 million for tax year 2017.

At June 30, 2017 and December 31, 2016 the company had $506.5 million and $507.0 million of gross state net operating loss carry-forwards expected to be utilized, respectively.

At June 30, 2017 and December 31, 2016, the Company had no unrecognized tax benefits and no material amounts recorded for uncertain tax positions.

Fair Value

Fair Value Disclosures [Abstract]

Fair Value

Fair Value

FASB guidance on fair value measurements defines fair value, establishes a framework for measuring fair value, and requires fair value disclosures for certain assets and liabilities measured at fair value on a recurring and non-recurring basis.

This guidance defines fair value as the exchange price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants in the principal or most advantageous market for the asset or liability.

This guidance establishes a fair value hierarchy for disclosure of fair value measurements to maximize the use of observable inputs, that is, inputs that reflect the assumptions market participants would use in pricing an asset or liability based on market data obtained from sources independent of the reporting entity. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity can access as of the measurement date.

Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.

Cash & cash equivalents

Cash and cash equivalents include cash on hand and highly-liquid items with an original maturity of three months or less. Accordingly, the carrying amount of such instruments is considered to be a reasonable estimate of fair value.

Derivative financial instruments

Interest rate swaps are valued by a third party, using models that primarily use market observable inputs, such as yield curves, and are validated by comparison with valuations provided by the respective counterparties. The credit risk associated with derivative financial instruments that are subject to master netting agreements is measured on a net basis by counterparty portfolio. Forward loan sales agreements are based upon the amounts required to settle the contracts. Fair values for commitments to originate loans held for sale are based on fees currently charged to enter into similar agreements. Fair values for fixed-rate commitments consider the difference between current levels of interest rates and the committed rates.

Valuation of Investment Securities

The fair values of available-for-sale, held-to-maturity and trading securities are determined by: 1) obtaining quoted prices on nationally recognized securities exchanges when available (Level 1 inputs); 2) matrix pricing, which is a mathematical technique widely used in the financial markets to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs); and 3) for certain other debt securities that are not actively traded, custom discounted cash flow modeling (Level 3 inputs).

As of June 30, 2017, the Bank held industrial revenue bonds, which are floating rate issues. Since there is no active secondary market for the trading of the bonds, the Company has developed a model to estimate fair value. This model determines an appropriate discount rate for the bonds based on current market rates for liquid corporate bonds with an equivalent credit rating plus an estimated illiquidity factor, and calculates the present value of expected future cash flows using this discount rate.

Mortgage Loans Held for Sale

Mortgage loans held for sale are carried at the lower of cost or estimated fair value. The fair values of mortgage loans held for sale are based on commitments on hand from investors within the secondary market for loans with similar characteristics. As such, the fair value adjustment for mortgage loans held for sale is classified as nonrecurring Level 2.

Valuation of Impaired Loans and Other Real Estate Owned

The fair value of collateral dependent impaired loans with specific allocations of the allowance for loan and lease losses and other real estate owned is generally based on recent real estate appraisals and other available observable market information. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach.

The Company generally uses independent external appraisers in this process who routinely make adjustments to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in a Level 3 classification of the inputs for determining fair value. The Company’s policy is to update appraisals, at a minimum, annually for classified assets, which include collateral dependent loans and OREO. The Company considers appraisals dated within the past 12 months to be current and do not typically make adjustments to such appraisals. In the Company’s process for reviewing third-party prepared appraisals, any differences of opinion on values, assumptions or adjustments to comparable sales data are typically reconciled directly with the independent appraiser prior to acceptance of the final appraisal.

Valuation of Premises and Equipment held for sale

Premises and equipment held for sale are carried at the lower of cost or estimated fair value. The fair values of premises and equipment held for sale are based on recent real estate appraisals and other available observable market information.

Mortgage Servicing Rights

As of June 30, 2017, the fair value of the Company's Level 3 mortgage servicing rights (“MSR”) was $2.5 million, none of which are currently impaired and therefore are carried at amortized cost. The assumptions used include the fee per loan, the cost to service, the expected loan prepayment rate, and the discount rate. In determining the fair value of the existing MSR, the Company reviews the key assumptions, analyzes pricing in the market for comparable MSR, and uses a third party provider to independently calculate the fair value of its MSR.

Sensitivity to Changes in Significant Unobservable Inputs

As discussed above, as of June 30, 2017, the Company owns industrial revenue bonds, which require recurring fair value estimates categorized within Level 3 of the fair value hierarchy. The significant unobservable inputs used in the fair value measurement of these securities are incorporated in the discounted cash flow modeling valuation. Rates utilized in the modeling of these securities are estimated based upon a variety of factors including the market yields of other non-investment grade corporate debt. Significant changes in any inputs in isolation would result in significantly different fair value estimates.

The methods and assumptions used to estimate fair value are described as follows:

Carrying amount is the estimated fair value for cash and cash equivalents, derivatives, noncontractual demand deposits and certain short-term borrowings. As it is not practicable to determine the fair value of Federal Home Loan Bank stock due to restrictions placed on transferability, the estimated fair value is equal to their carrying amount. Security fair values are based on market prices or dealer quotes and, if no such information is available, on the rate and term of the security and information about the issuer including estimates of discounted cash flows when necessary. For fixed rate loans or contractual deposits and for variable rate loans or deposits with infrequent repricing or repricing limits, fair value is based on discounted cash flows using current market rates applied to the estimated life, adjusted for the allowance for loan and lease losses. Fair values for impaired loans are estimated using discounted cash flow analysis or underlying collateral values. Fair value of loans does not necessarily represent exit price. Fair value of long-term debt is based on current rates for similar financing. The fair value of off-balance sheet items that include commitments to extend credit to fund commercial, consumer, real estate construction and real estate-mortgage loans and to fund standby letters of credit is considered nominal.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative and Hedging Activities

Derivative and Hedging Activities

The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates.

The Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. The Company may enter into derivative contracts that are intended to economically hedge certain of its risks, even though hedge accounting does not apply or the Company elects not to apply hedge accounting.

During 2015, the company entered into LIBOR-based interest rate swaps with the objective of limiting the variability of interest payment cash flows resulting from changes in the benchmark interest rate LIBOR. These interest rate swaps are designated as cash flow hedges involving the receipt of fixed-rate amounts from a counterparty in exchange for the Company making variable-rate payments over the life of the agreements without exchange of the underlying notional amount. The effective portion of changes in the fair value of the derivatives is recorded in accumulated other comprehensive income and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. Any ineffective portion of a financial instrument’s change in fair value is immediately recognized in earnings.

During the next twelve months, the Company estimates that an additional $0.4 million will be reclassified as a decrease to interest income from amounts reported in accumulated comprehensive income. During the six months endedJune 30, 2017, no derivative position designated as cash flow hedges were discontinued and none of the gains and losses reported in other comprehensive income were reclassified into earnings as a result of discontinuance of cash flow hedges.

During the second quarter of 2016, the company implemented an interest rate swap program to allow customers to convert variable rate loans to fixed rates. The interest rate swaps are simultaneously offset by interest rate swaps that the Company executes with its derivative counterparties. The changes in the fair value of the swaps offset each other, except for any differences in the credit risk of the counterparties. None of these interest rate swaps are designated or qualify as hedging relationships. As the interest rate swaps associated with this program do not meet hedge accounting requirements, changes in fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. The Company recorded $0.2 million of customer swap fees in non-interest income for the six months ended June 30, 2017.

The Company also enters into forward loan sales contracts, which are derived from loans held for sale, or in the Company’s pipeline, to enable those borrowers to manage their exposure to interest rate fluctuations. The forward loan sales derivative contracts are not designated as hedging instruments and all changes in fair value are recognized in non-interest income or non-interest expense during the period of change. For the six months endedJune 30, 2017, the Company recorded $29 thousand in non-interest income and $113 thousand in non-interest expense as a result of changes in fair value of derivatives. For the six months endedJune 30, 2016, the company recorded $57 thousand in non-interest income and $2 thousand in non-interest expense as a result of changes in fair value of derivatives.

The Company’s derivative instrument contracts at fair value as well as their classification on the Company's Consolidated Balance Sheet is presented below:

The amount of collateral received and posted disclosed in the table above represents the offset of the assets and liabilities as of June 30, 2017. The actual cash collateral received and posted amounted to $0.3 million and $0.5 million, respectively.

The Company has agreements with certain of its derivative counterparties that contain a provision where if the Company defaults on any of its indebtedness or fails to maintain its status as a well-capitalized institution, then the Company could also be declared in default on its derivative obligations and could be required to terminate its derivative positions with the counterparty and settle the termination value of derivatives in a liability position.

As of June 30, 2017, there were eleven derivatives in a $2.0 million net liability position, which includes accrued interest and excludes nonperformance risk, related to these agreements. The Company is exposed to credit-related losses in the event of nonperformance by the counterparties to these agreements. The Company controls the credit risk of its financial contracts through credit approvals, limits and monitoring procedures and agreements that specify collateral levels to be maintained by the Company and the counterparties. The company has minimum collateral posting thresholds with certain derivative counterparties, and has posted $0.5 million of cash collateral against its obligations under these agreements as of June 30, 2017.

Nature of Operations and Principles of Consolidation

Nature of Operations and Principles of Consolidation

Capital Bank Financial Corp. (“CBF” or the “Company”; formerly known as North American Financial Holdings, Inc.) is a bank holding company incorporated in late 2009 in Delaware and headquartered in North Carolina whose business is conducted primarily through Capital Bank Corporation (“Capital Bank Corporation” or the “Bank”). The Company was incorporated with the goal of creating a regional banking franchise in the southeastern region of the United States through organic growth and acquisitions of other banks, including failed, underperforming and undercapitalized banks. CBF has raised $955.6 million to make acquisitions through a series of private placements and an initial public offering of its common stock. Since inception, CBF has acquired eight depository institutions, including the assets and certain deposits from failed banks. CBF has a total of 189 full service banking offices located in Florida, North and South Carolina, Tennessee and Virginia. During the six months endedJune 30, 2017, the Company closed and consolidated seven branches in conjunction with the merger of CommunityOne. The Company expects to close and consolidate an additional elevenbranches during 2017. As such, the Company transferred $18.1 million from fixed assets to bank properties held for sale during the six months endedJune 30, 2017.

The accompanying unaudited Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and Regulation S-X. Accordingly, they do not include all of the information and disclosures required by U.S. GAAP for complete financial statement presentation. In the opinion of management, all adjustments consisting of normal recurring accruals and disclosures considered necessary for a fair interim presentation have been included. All significant inter-company accounts and transactions have been eliminated in consolidation. For further information, refer to the Company’s Consolidated Financial Statements and notes thereto included in the Company’s annual report on Form 10-K for the fiscal year ended December 31, 2016.

Proposed merger with First Horizon National Corporation

On May 4, 2017, Capital Bank Financial Corp. issued a press release announcing the execution of an agreement and plan of merger with First Horizon National Corporation (the “First Horizon”) dated May 3, 2017, with First Horizon as the surviving corporation. Subject to terms and conditions of the Merger Agreement, each holder of Capital Bank common stock will be entitled to receive cash or stock with a value equivalent to 1.750 First Horizon shares and $7.90 in cash for each Capital Bank share held, subject to the election allocation and proration provisions of the merger agreement. The transaction is subject to shareholder and regulatory approvals in addition to satisfying certain other closing conditions.

Use of Estimates and Assumptions

Use of Estimates and Assumptions

To prepare financial statements in conformity with U.S. GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as presented in the financial statements. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In March 2017, the Financial Accounting Standard Board (the “FASB”) issued Accounting Standards Update ("ASU") 2017-09, "Compensation—Stock Compensation (Topic 718)". The amendments in this update provide guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in Topic 718. An entity should account for the effects of a modification unless all the following are met: (1) the fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the modified award is the same as the fair value (or calculated value or intrinsic value, if such an alternative measurement method is used) of the original award immediately before the original award is modified. If the modification does not affect any of the inputs to the valuation technique that the entity uses to value the award, the entity is not required to estimate the value immediately before and after the modification, (2) the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified, (3) the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2017. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In March 2017, the FASB issued ASU 2017-08, "Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20) Premium Amortization on Purchased Callable Debt Securities". The amendments in this update affect all entities that have an amortized cost basis in excess of the amount that is repayable by the issuer at the earliest call date. The objective is to shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. Securities held at a discount continue to be amortized to maturity. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2018. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In March 2017, the FASB issued ASU 2017-07, "Compensation - Retirement Benefits (Topic 715)". The amendments in this update require that an employer report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost as defined in paragraphs 715-30-35-4 and 715-60-35-9 are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. If a separate line item or items are used to present the other components of net benefit cost, that line item or items must be appropriately described. If a separate line item or items are not used, the line item or items used in the income statement to present the other components of net benefit cost must be disclosed. The amendments in this update also allow only the service cost component to be eligible for capitalization when applicable (for example, as a cost of internally manufactured inventory or a self-constructed asset). The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2017. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In January 2017, the FASB issued ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350)". The amendments in this update aim to simplify the subsequent measurement of goodwill. Under these amendments, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. The FASB also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment. An entity is required to disclose the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets and still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2019. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In January 2017, the FASB issued ASU 2017-01, "Business Combinations (Topic 805)". The amendments in this update provide a screen to determine when a set is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The amendments in this update should be applied prospectively on or after the effective date. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In May 2016, the FASB issued ASU 2016-12, "Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients". The amendments in this Update represent minor corrections or improvements to narrow aspects of Topic 606, as amended by ASU No. 2014-09, and do not change the core principle of the guidance in Topic 606. The effective date and transition requirements for the amendments in this Update are the same as the effective date and transition requirements for Topic 606 (and any other Topic amended by Update 2014-09), which is not yet effective. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows—Credit Losses (Topic 230)". The amendments in this update provide guidance on the following eight specific cash flow issues: (1) Debt prepayment or debt extinguishment costs; (2) Settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; (3) Contingent consideration payments made after a business combination; (4) Proceeds from the settlement of insurance claims; (5) Proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; (6) Distributions received from equity method investees; (7) Beneficial interests in securitization transactions; (8) Separately identifiable cash flows and application of the predominance principle. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments—Credit Losses (Topic 326)". The main objective of this update is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates and affects loans, debt securities, trade receivables, net investments in leases, off-balance-sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. For public business entities that are U.S. Securities and Exchange Commission (SEC) filers, the amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In March 2016, the FASB issued ASU 2016-9, "Compensation—Stock compensation (Topic 718)". Improvements to employee share-based payment accounting" which objective is the simplification through the identification, evaluation, and improvement of areas of generally accepted accounting principles (GAAP) for which cost and complexity can be reduced while maintaining or improving the usefulness of the information provided to users of financial statements. The areas for simplification involve several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Some of the areas for simplification apply only to nonpublic entities. We early adopted ASU 2016-09 during the fourth quarter of 2016 and prior periods were modified retrospectively. The adoption did not have a material impact on the Company's consolidated financial statements. The impact resulted in, among other items, a $0.1 million increase to net income and a $0.01 increase to earnings per share for the six months endedJune 30, 2016. The Company reflected these adjustments in our disclosures including the consolidated financial statements, earnings per common share, business combination and acquisitions, stock-based compensation, and income taxes.

In March 2016, the FASB issued ASU No. 2016-08, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net)”. The amendments in this update will clarify the implementation guidance on principal versus agent considerations. Topic 606 requires an entity to determine whether the nature of its promise is to provide that good or service to the customer (that is, the entity is a principal) or to arrange for the good or service to be provided to the customer by the other party (that is, the entity is an agent). This determination is based upon whether the entity controls the good or the service before it is transferred to the customer. Topic 606 includes indicators to assist in this evaluation. The effective date and transition requirements for the amendments in this update are the same as the effective date and transition requirements for Topic 606 (and any other Topic amended by update 2014-09 listed below), which is not yet effective. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In March 2016, the FASB issued ASU 2016-7, "Investments—Equity Method and Joint Ventures (Topic 323)". The amendments in this update eliminate the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments in this update require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The amendments in this update are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The amendments should be applied prospectively upon their effective date to increases in the level of ownership interest or degree of influence that result in the adoption of the equity method. Earlier application is permitted. The adoption did not have a material impact on the Company's consolidated financial statements.

In March 2016, the FASB issued ASU 2016-6, "Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments". The amendments in this update clarify the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments in this update is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. For public business entities, the amendments in this update are effective for financial statements issued for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The adoption did not have a material impact on the Company's consolidated financial statements.

In January 2016, the FASB issued ASU 2016-2, "Leases (Topic 842)" which increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. To meet that objective, the FASB is amending the FASB Accounting Standards Codification and creating Topic 842, Leases. This update, along with IFRS 16, Leases, are the results of the FASB’s and the International Accounting Standards Board’s (IASB’s) efforts to meet that objective and improve financial reporting. The FASB and IASB decided to not fundamentally change lessor accounting with the amendments in this update. However, some changes have been made to lessor accounting to conform and align that guidance with the lessee guidance and other areas within generally accepted accounting principles (GAAP), such as Topic 606, Revenue from Contracts with Customers. The main difference between previous GAAP and Topic 842 is the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. For public business entities, the amendments in ASU 2016-2 are effective for fiscal years beginning after December 15, 2018. The Company is currently evaluating this ASU to determine the impact on its consolidated financial position, results of operations and cash flows.

In January 2016, the FASB issued ASU 2016-1, "Financial instruments—Overall (Subtopic 825-10)" which requires all equity investments to be measured at fair value with changes in the fair value recognized through net income (other than those accounted for under equity method of accounting or those that result in consolidation of the investee). The amendments in this update also require an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. In addition, the amendments in this update eliminate the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities and the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet for public business entities. For public business entities, the amendments in ASU 2016-1 are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of ASU 2016-1 is not expected to have a material impact on the Company's consolidated financial position, results of operations and cash flows.

In May 2014, the FASB issued ASU 2014-9, "Revenue from Contracts with Customers (Topic 606)". The core principle of Topic 606 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies the performance obligation. In August 2015, the FASB issued ASU 2015-14, "Revenue from contracts with customers (Topic 606) - Deferral of the Effective Date". The amendments in ASU 2015-14 establish December 15, 2017 as the effective date of the information related to ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)”. While we anticipate some changes, the Company does not expect a material change from our current accounting for revenue as the majority of our interest and non-interest income is not in scope of Topic 606.

Earnings Per Common Share

Earnings Per Common Share

Basic earnings per share is computed as net income attributable to common shareholders divided by the weighted average number of common shares outstanding during the period. Diluted earnings per share include the dilutive effect of additional potential common shares issuable under stock options and unvested restricted shares computed using the treasury stock method.

Fair Value

FASB guidance on fair value measurements defines fair value, establishes a framework for measuring fair value, and requires fair value disclosures for certain assets and liabilities measured at fair value on a recurring and non-recurring basis.

This guidance defines fair value as the exchange price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants in the principal or most advantageous market for the asset or liability.

This guidance establishes a fair value hierarchy for disclosure of fair value measurements to maximize the use of observable inputs, that is, inputs that reflect the assumptions market participants would use in pricing an asset or liability based on market data obtained from sources independent of the reporting entity. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity can access as of the measurement date.

Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.

Cash & cash equivalents

Cash and cash equivalents include cash on hand and highly-liquid items with an original maturity of three months or less. Accordingly, the carrying amount of such instruments is considered to be a reasonable estimate of fair value.

Derivative financial instruments

Interest rate swaps are valued by a third party, using models that primarily use market observable inputs, such as yield curves, and are validated by comparison with valuations provided by the respective counterparties. The credit risk associated with derivative financial instruments that are subject to master netting agreements is measured on a net basis by counterparty portfolio. Forward loan sales agreements are based upon the amounts required to settle the contracts. Fair values for commitments to originate loans held for sale are based on fees currently charged to enter into similar agreements. Fair values for fixed-rate commitments consider the difference between current levels of interest rates and the committed rates.

Valuation of Investment Securities

The fair values of available-for-sale, held-to-maturity and trading securities are determined by: 1) obtaining quoted prices on nationally recognized securities exchanges when available (Level 1 inputs); 2) matrix pricing, which is a mathematical technique widely used in the financial markets to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs); and 3) for certain other debt securities that are not actively traded, custom discounted cash flow modeling (Level 3 inputs).

As of June 30, 2017, the Bank held industrial revenue bonds, which are floating rate issues. Since there is no active secondary market for the trading of the bonds, the Company has developed a model to estimate fair value. This model determines an appropriate discount rate for the bonds based on current market rates for liquid corporate bonds with an equivalent credit rating plus an estimated illiquidity factor, and calculates the present value of expected future cash flows using this discount rate.

Mortgage Loans Held for Sale

Mortgage loans held for sale are carried at the lower of cost or estimated fair value. The fair values of mortgage loans held for sale are based on commitments on hand from investors within the secondary market for loans with similar characteristics. As such, the fair value adjustment for mortgage loans held for sale is classified as nonrecurring Level 2.

Valuation of Impaired Loans and Other Real Estate Owned

The fair value of collateral dependent impaired loans with specific allocations of the allowance for loan and lease losses and other real estate owned is generally based on recent real estate appraisals and other available observable market information. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach.

The Company generally uses independent external appraisers in this process who routinely make adjustments to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in a Level 3 classification of the inputs for determining fair value. The Company’s policy is to update appraisals, at a minimum, annually for classified assets, which include collateral dependent loans and OREO. The Company considers appraisals dated within the past 12 months to be current and do not typically make adjustments to such appraisals. In the Company’s process for reviewing third-party prepared appraisals, any differences of opinion on values, assumptions or adjustments to comparable sales data are typically reconciled directly with the independent appraiser prior to acceptance of the final appraisal.

Valuation of Premises and Equipment held for sale

Premises and equipment held for sale are carried at the lower of cost or estimated fair value. The fair values of premises and equipment held for sale are based on recent real estate appraisals and other available observable market information.

Mortgage Servicing Rights

As of June 30, 2017, the fair value of the Company's Level 3 mortgage servicing rights (“MSR”) was $2.5 million, none of which are currently impaired and therefore are carried at amortized cost. The assumptions used include the fee per loan, the cost to service, the expected loan prepayment rate, and the discount rate. In determining the fair value of the existing MSR, the Company reviews the key assumptions, analyzes pricing in the market for comparable MSR, and uses a third party provider to independently calculate the fair value of its MSR.

Sensitivity to Changes in Significant Unobservable Inputs

As discussed above, as of June 30, 2017, the Company owns industrial revenue bonds, which require recurring fair value estimates categorized within Level 3 of the fair value hierarchy. The significant unobservable inputs used in the fair value measurement of these securities are incorporated in the discounted cash flow modeling valuation. Rates utilized in the modeling of these securities are estimated based upon a variety of factors including the market yields of other non-investment grade corporate debt. Significant changes in any inputs in isolation would result in significantly different fair value estimates.

The methods and assumptions used to estimate fair value are described as follows:

Carrying amount is the estimated fair value for cash and cash equivalents, derivatives, noncontractual demand deposits and certain short-term borrowings. As it is not practicable to determine the fair value of Federal Home Loan Bank stock due to restrictions placed on transferability, the estimated fair value is equal to their carrying amount. Security fair values are based on market prices or dealer quotes and, if no such information is available, on the rate and term of the security and information about the issuer including estimates of discounted cash flows when necessary. For fixed rate loans or contractual deposits and for variable rate loans or deposits with infrequent repricing or repricing limits, fair value is based on discounted cash flows using current market rates applied to the estimated life, adjusted for the allowance for loan and lease losses. Fair values for impaired loans are estimated using discounted cash flow analysis or underlying collateral values. Fair value of loans does not necessarily represent exit price. Fair value of long-term debt is based on current rates for similar financing. The fair value of off-balance sheet items that include commitments to extend credit to fund commercial, consumer, real estate construction and real estate-mortgage loans and to fund standby letters of credit is considered nominal.
