Notes to Unaudited Consolidated Financial Statements

NOTE A - ACCOUNTING POLICIES AND BASIS OF PRESENTATION

First Citizens BancShares, Inc. (BancShares) is a financial holding company organized under the laws of Delaware and conducts operations through its banking subsidiary, First-Citizens Bank & Trust Company (FCB), which is headquartered in Raleigh, North Carolina.

General

These consolidated financial statements and notes thereto are presented in accordance with instructions for Form 10-Q and Article 10 of Regulation S-X and, therefore, do not include all information and notes necessary for a complete presentation of financial position, results of operations and cash flow activity required in accordance with accounting principles generally accepted in the United States of America (GAAP). In the opinion of management, all normal recurring adjustments necessary for a fair presentation of the consolidated financial position and consolidated results of operations have been made. The unaudited interim consolidated financial statements included in this Form 10-Q should be read in conjunction with the consolidated financial statements and notes to consolidated financial statements included in BancShares' Annual Report on Form 10-K for the year ended December 31, 2018.

Reclassifications

In certain instances, amounts reported in prior years' consolidated financial statements have been reclassified to conform to the current financial statement presentation. Such reclassifications had no effect on previously reported cash flows, shareholders' equity or net income.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported. Actual results could differ from those estimates. The estimates that BancShares considers significant are the allowance for loan and lease losses, fair value measurements, Federal Deposit Insurance Corporation (FDIC) shared-loss payable, pension plan assumptions, goodwill and other intangible assets, and income taxes.

Share Repurchases

In October 2018, BancShares' Board of Directors (Board) authorized the repurchase of up to 800,000 of BancShares' Class A common stock for the period November 1, 2018 through October 31, 2019. The authorization does not obligate BancShares to repurchase any particular amount of shares, and repurchases may be suspended or discontinued at any time. During the second quarter of 2019, BancShares repurchased 205,500 shares of Class A common stock for $89.8 million at an average cost per share of $436.81. During the first six months of 2019, BancShares repurchased a total of 448,500 shares of Class A common stock for $190.5 million at an average cost per share of $424.77. As of June 30, 2019, a total of 630,500 shares have been repurchased under the current Board authority. There were no share repurchases made during the comparable periods in 2018.

In April 2019, the Board authorized the repurchase of up to 800,000 of BancShares' Class A common stock for the period July 1, 2019 through June 30, 2020. This authorization was effective July 1, 2019 and supersedes the authorization approved in October 2018. Under this authorization and subsequent to quarter-end through August 2, 2019, BancShares repurchased an additional 69,600 shares of Class A common stock for $31.7 million at an average cost per share of $455.94.

Recently Adopted Accounting Pronouncements

Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) 2016-02, Leases (Topic 842)

This ASU increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The key difference between prior standards and this ASU is the requirement for lessees to recognize all lease contracts on their balance sheet. This ASU requires lessees to classify leases as either operating or finance leases, which are substantially similar to the previous operating and capital leases classifications. The distinction between these two classifications under the new standard does not relate to balance sheet treatment, but relates to treatment in the statements of income and cash flows. Lessor guidance remains largely unchanged with the exception of how a lessor determines the appropriate lease classification for each lease to better align the lessor guidance with revised lessee classification guidance.

We adopted this standard, as of January 1, 2019, using the effective date method that allows for entities to initially apply the new leases standard at the adoption date. In addition, we made several policy elections permitted under the transition guidance, which among other things, allowed us to carry forward the historical lease classification. We determined that most renewal options would not be reasonably determinable in estimating the expected lease term.

8

We made the policy election available under Topic 842 to combine lease and non-lease components and applied this practical expedient to leases in effect prior to the date of adoption. We will continue to apply the practical expedient to all leases entered into going forward.

The adoption of the new standard had an impact on our Consolidated Balance Sheet as of January 1, 2019, with the recording of operating Right-of-Use (ROU) assets and operating lease liabilities of $70.7 million and $71.8 million, respectively. The operating lease liability includes a $1.1 million fair value adjustment for leases assumed in the acquisition of HomeBancorp, Inc. (HomeBancorp). In addition, at the adoption date we had finance lease ROU assets and finance lease liabilities, previously classified as capital leases, of $9.1 million and $8.3 million, respectively.  The Company did not have a cumulative-effect adjustment to the opening balance of retained earnings at commencement. The Company has no related party lease agreements.  This ASU did not have a material impact on our Consolidated Statements of Income. See Note N in the Consolidated Financial Statements for additional disclosures.

Recently Issued Accounting Pronouncements

FASB ASU 2018-15 - Intangibles - Goodwill and Other - Internal Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract

This ASU aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include internal-use software license). This ASU requires entities to use the guidance in FASB ASC 350-40, Intangibles - Goodwill and Other - Internal Use Software, to determine whether to capitalize or expense implementation costs related to the service contract. This ASU also requires entities to (1) expense capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement (2) present the expense related to the capitalized implementation costs in the same line item on the income statement as fees associated with the hosting element of the arrangement (3) classify payments for capitalized implementation costs in the statement of cash flows in the same manner as payments made for fees associated with the hosting element (4) present the capitalized implementation costs in the same balance sheet line item that a prepayment for the fees associated with the hosting arrangement would be presented.

The amendments in this ASU are effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted. BancShares adopted this standard effective July 1, 2019 on a prospective basis. BancShares is currently evaluating the impact of this ASU adoption, but does not anticipate a material impact on our Consolidated Financial Statements.

FASB ASU 2018-14 - Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans

This ASU modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans by eliminating the requirement to disclose the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year and adding a requirement to disclose an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period.

The amendments in this ASU are effective for public entities for fiscal years ending after December 15, 2020. Early adoption is permitted for all entities. BancShares will adopt all applicable amendments and update the disclosures as appropriate during the first quarter of 2021.

FASB ASU 2018-13 - Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement

This ASU modifies the disclosure requirements on fair value measurements by eliminating the requirements to disclose (1) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy (2) the policy for timing of transfers between levels and (3) the valuation processes for Level 3 fair value measurements. This ASU also added specific disclosure requirements for fair value measurements for public business entities including the requirement to disclose the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements.

The amendments in this ASU are effective for all entities for fiscal years beginning after December 15, 2019, and all interim periods within those fiscal years. Early adoption is permitted upon issuance of the ASU. Entities are permitted to early adopt amendments that remove or modify disclosures and delay the adoption of the additional disclosures until their effective date. BancShares will adopt all applicable amendments and update the disclosures as appropriate during the first quarter of 2020.

FASB ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment

This ASU eliminates Step 2 from the goodwill impairment test. Under Step 2, an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities) following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, under the amendments in this ASU, 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. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. This ASU eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative test.

This ASU will be effective for BancShares' annual or interim goodwill impairment tests for fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We expect to adopt the guidance for our annual impairment test in fiscal year 2020. BancShares does not anticipate any impact to our consolidated financial position or consolidated results of operations as a result of the adoption.

FASB ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments

This ASU introduces a new credit loss methodology which requires earlier recognition of credit losses, replacing multiple existing impairment methods in current GAAP, which generally require that a loss be incurred before it is recognized. The amendments in this ASU require loss estimates be determined over the lifetime of the asset and broaden the information that an entity must consider in developing its expected credit losses. The ASU does not specify a method for measuring expected credit losses and allows an entity to apply methods that reasonably reflect its expectations of the credit loss estimate based on the entity's size, complexity and risk profile. In addition, the disclosures of credit quality indicators in relation to the amortized cost of financing receivables, a current disclosure requirement, are further disaggregated by year of origination.

For BancShares, the standard will apply to loans, unfunded loan commitments and debt securities. A cross-functional team co-led by Corporate Finance and Risk Management is in place to implement the new standard. We have completed preliminary current expected credit losses (CECL) accounting interpretations, and continue to refine and test our models, estimation techniques, data, operational processes and controls to be used in preparing CECL loss estimates. During the remainder of 2019, we expect to address any gaps in our interpretations, including review of subsequent ASUs announced by the FASB regarding Topic 326, methodology, data and operational processes based upon our reviews and tests. BancShares continues to evaluate the impact of this standard on its consolidated financial statements but the magnitude of this impact has not been determined. The final impact will be dependent on, among other items, loan portfolio composition and credit quality at the adoption date, as well as economic conditions, financial models used and forecasts in place at that time.

The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018. BancShares will adopt the guidance in the first quarter of 2020 with a cumulative-effect adjustment to retained earnings as of the beginning of the year of adoption.

NOTE B - BUSINESS COMBINATIONS

Entegra Financial Corp.

On April 23, 2019, FCB and Entegra Financial Corp. (Entegra) entered into a definitive merger agreement for the acquisition by FCB of Franklin, North Carolina-based Entegra and its bank subsidiary, Entegra Bank. Under the terms of the agreement, cash consideration of $30.18 per share will be paid to the shareholders of Entegra for each share of common stock and for each restricted stock unit after conversion to common stock, and each option to purchase Entegra common stock will be canceled and each option holder will receive a cash payment.The total transaction value is estimated to be approximately $219.8 million. The transaction is anticipated to close during the fourth quarter of 2019, subject to the receipt of regulatory approvals and the satisfaction of other customary closing conditions. As of June 30, 2019, Entegra reported $1.66 billion in consolidated assets, $1.25 billion in deposits and $1.09 billion in loans.

First South Bancorp, Inc.

On May 1, 2019, FCB completed the merger of Spartanburg, South Carolina-based First South Bancorp, Inc. (First South Bancorp) and its bank subsidiary, First South Bank. Under the terms of the agreement, cash consideration of $1.15 per share was paid to the shareholders of First South Bancorp for each share of common stock, totaling approximately $37.5 million. The merger allows FCB to expand its presence in South Carolina.

10

The First South Bancorp transaction was accounted for under the acquisition method of accounting and, accordingly, assets acquired and liabilities assumed were recorded at their estimated fair values on the acquisition date. Fair values are preliminary and subject to refinement for up to one year after the closing date of the acquisition as additional information regarding closing date fair values becomes available.

The fair value of the assets acquired was $239.2 million, including $162.8 million in non-purchased credit impaired (non-PCI) loans, $16.4 million in purchased credit impaired (PCI) loans and $2.3 million in a core deposit intangible. Liabilities assumed were $215.6 million, of which $207.6 million were deposits. As a result of the transaction, FCB recorded $13.9 million of goodwill. The amount of goodwill represents the excess purchase price over the estimated fair value of the net assets acquired. The premium paid reflects the increased market share and related synergies that are expected to result from the acquisition. None of the goodwill was deductible for income tax purposes as the merger was accounted for as a qualified stock purchase.

Based on such credit factors as past due status, nonaccrual status, loan-to-value, credit scores, and other quantitative and qualitative considerations, the acquired loans were separated into loans with evidence of credit deterioration, which are accounted for under ASC 310-30 (PCI loans), and loans that do not meet this criteria, which are accounted for under ASC 310-20 (non-PCI loans).

The following table provides the purchase price as of the acquisition date and the identifiable assets acquired and liabilities assumed at their estimated fair values:

(Dollars in thousands)	As recorded by FCB
Purchase price			$	37,486

Merger-related expenses of $1.2 million and $1.4 million were recorded in the Consolidated Statements of Income for the three and six months ended June 30, 2019, respectively. Loan-related interest income generated from First South Bancorp was approximately $1.7 million since the acquisition date. The ongoing contributions of this transaction to BancShares' financial statements is not considered material, and therefore pro forma financial data is not included.

Biscayne Bancshares, Inc.

On April 2, 2019, FCB completed the merger of Coconut Grove, Florida-based Biscayne Bancshares, Inc. (Biscayne Bancshares) and its bank subsidiary, Biscayne Bank. Under the terms of the agreement, cash consideration of $25.05 per share was paid to the shareholders of Biscayne Bancshares for each share of common stock, totaling approximately $118.9 million. The merger will allow FCB to expand its presence in Florida and enhance banking efforts in South Florida.

The Biscayne Bancshares transaction was accounted for under the acquisition method of accounting and, accordingly, assets acquired and liabilities assumed were recorded at their estimated fair values on the acquisition date. Fair values are preliminary and subject to refinement for up to one year after the closing date of the acquisition as additional information regarding closing date fair values becomes available.

The fair value of the assets acquired was $1.03 billion, including $850.4 million in non-purchased credit impaired (non-PCI) loans, $13.0 million in purchased credit impaired (PCI) loans and $4.7 million in a core deposit intangible. Liabilities assumed were $956.8 million, of which $786.5 million were deposits. As a result of the transaction, FCB recorded $46.5 million of goodwill. The amount of goodwill represents the excess purchase price over the estimated fair value of the net assets acquired. The premium paid reflects the increased market share and related synergies that are expected to result from the acquisition. None of the goodwill was deductible for income tax purposes as the merger was accounted for as a qualified stock purchase.

As of June 30, 2019, there were 200 investment securities available for sale that had continuous losses for more than 12 months of which 197 were government sponsored enterprise-issued mortgage-backed securities or government agency securities, one was a U.S. Treasury security and two were corporate bonds.

None of the unrealized losses identified as of June 30, 2019 or December 31, 2018 relate to the marketability of the securities or the issuers' ability to honor redemption obligations. Rather, the unrealized losses relate to changes in interest rates relative to when the debt securities were purchased. BancShares has the ability and intent to retain these securities for a period of time sufficient to recover all unrealized losses. Therefore, none of the securities were deemed to be other than temporarily impaired.

Debt securities having an aggregate carrying value of $3.75 billion at June 30, 2019 and $4.03 billion at December 31, 2018 were pledged as collateral to secure public funds on deposit and certain short-term borrowings, and for other purposes as required by law.

NOTE D - LOANS AND LEASES

BancShares' accounting methods for loans and leases differ depending on whether they are non-purchased credit impaired (Non-PCI) or purchased credit impaired (PCI). Loans that were originated by FCB, as well as loans that are performing under their contractual obligations at acquisition, are classified as Non-PCI. Loans that reflect credit deterioration since origination, such that it is probable at acquisition that FCB will be unable to collect all contractually required payments, are classified as PCI. Additionally, at the date of acquisition, all acquired loans are recorded at fair value with no corresponding allowance for loan and lease losses.

At June 30, 2019, $9.16 billion in non-PCI loans with a lendable collateral value of $6.45 billion were used to secure $183.7 million in Federal Home Loan Bank (FHLB) of Atlanta advances and $13.5 million in FHLB of Chicago advances, resulting in additional borrowing capacity of $6.26 billion. At December 31, 2018, $9.12 billion in non-PCI loans with a lendable collateral value of $6.36 billion were used to secure $175.2 million in FHLB of Atlanta advances, resulting in additional borrowing capacity of $6.18 billion.

At June 30, 2019, $2.73 billion in non-PCI loans with a lendable collateral value of $2.09 billion were used to secure additional borrowing capacity at the Federal Reserve Bank (FRB). At December 31, 2018, $2.94 billion in non-PCI loans with a lendable collateral value of $2.19 billion were used to secure additional borrowing capacity at the FRB.

Certain residential real estate loans are originated to be sold to investors and are recorded in loans held for sale at fair value. In addition, we may change our strategy for certain portfolio loans and decide to sell them in the secondary market. At that time, portfolio loans are transferred to loans held for sale at fair value. Since December 31, 2018, $23.9 million in portfolio loans were transfered to held for sale and subsequently sold. Loans held for sale totaled $52.8 million and $45.5 million at June 30, 2019 and December 31, 2018, respectively.

Net deferred fees on non-PCI loans and leases, including unearned income as well as unamortized costs and fees, were $0.5 million and $0.1 million at June 30, 2019 and December 31, 2018, respectively. The net unamortized discount related to purchased non-PCI loans and leases was $35.7 million at June 30, 2019 and $33.3 million at December 31, 2018. During the three months ended June 30, 2019 and June 30, 2018, accretion income on purchased non-PCI loans and leases was $3.3 million and $4.1 million, respectively. During the six months ended June 30, 2019 and June 30, 2018, accretion income on purchased non-PCI loans and leases was $6.5 million and $7.0 million, respectively.

Credit quality indicators

Loans and leases are monitored for credit quality on a recurring basis. Commercial and noncommercial loans and leases have different credit quality indicators as a result of the unique characteristics of the loan segments being evaluated. The credit quality indicators for non-PCI and PCI commercial loans and leases are developed through a review of individual borrowers on an ongoing basis. Commercial loans are evaluated periodically with more frequent evaluations done on criticized loans. Commercial credit cards are included in the Commercial and industrial and leases segment, but are not specifically graded as with other commercial loans. The indicators as of the date presented are based on the most recent assessment performed and are defined below:

Pass – A pass rated asset is not adversely classified because it does not display any of the characteristics for adverse classification.

Special mention – A special mention asset has potential weaknesses that deserve management’s close attention. If left uncorrected, such potential weaknesses may result in deterioration of the repayment prospects or collateral position at some future date. Special mention assets are not adversely classified and do not warrant adverse classification.

Substandard – A substandard asset is inadequately protected by the current net worth and paying capacity of the borrower or of the collateral pledged, if any. Assets classified as substandard generally have a well-defined weakness, or weaknesses, that jeopardize the liquidation of the debt. These assets are characterized by the distinct possibility of loss if the deficiencies are not corrected.

Doubtful – An asset classified as doubtful has all the weaknesses inherent in an asset classified substandard with the added characteristic that the weaknesses make collection or liquidation in full highly questionable and improbable on the basis of currently existing facts, conditions and values.

Loss – Assets classified as loss are considered uncollectible and of such little value that it is inappropriate to be carried as an asset. This classification is not necessarily equivalent to any potential for recovery or salvage value, but rather that it is not appropriate to defer a full charge-off even though partial recovery may be affected in the future.

Ungraded – Ungraded loans represent loans that are not included in the individual credit grading process due to their relatively small balances or borrower type. The majority of ungraded loans at June 30, 2019 and December 31, 2018 relate to business credit cards. Business credit card loans are subject to automatic charge-off when they become 120 days past due in the same manner as unsecured consumer lines of credit. The remaining balance is comprised of a small amount of commercial mortgage, lease financing and other commercial real estate loans.

The credit quality indicators for non-PCI and PCI noncommercial loans are based on delinquency status of the borrower as of the date presented. As the borrower becomes more delinquent, the likelihood of loss increases.

The carrying value of PCI loans on the cost recovery method was $3.3 million at both June 30, 2019 and December 31, 2018. The cost recovery method is applied to loans when the timing of future cash flows cannot be reasonably estimated due to borrower nonperformance or uncertainty in the ultimate disposition of the asset. The recorded investment of PCI loans on nonaccrual status was $4.3 million and $1.3 million at June 30, 2019 and December 31, 2018, respectively. The remaining discount on PCI loans was $93.0 million and $95.5 million at June 30, 2019 and December 31, 2018, respectively.

During the three months ended June 30, 2019 and June 30, 2018, accretion income on PCI loans was $11.9 million and $14.2 million, respectively. During the six months ended June 30, 2019 and June 30, 2018, accretion income on PCI loans was $29.6 million and $32.2 million, respectively.

For PCI loans, improved credit loss expectations generally result in the reclassification of nonaccretable difference to accretable yield. Changes in expected cash flow not related to credit improvements or deterioration do not affect the nonaccretable difference.

The following table documents changes to the amount of accretable yield for the first six months of 2019 and 2018:

Troubled Debt Restructurings

BancShares accounts for certain loan modifications or restructurings as troubled debt restructurings (TDRs). In general, the modification or restructuring of a loan is considered a TDR if, for economic reasons or legal reasons related to a borrower's financial difficulties, a concession is granted to the borrower that creditors would not otherwise consider. Concessions may relate to the contractual interest rate, maturity date, payment structure or other actions. The majority of TDRs are included in the special mention, substandard or doubtful credit quality indicators, which results in more elevated loss expectations when projecting the expected cash flows that are used to determine the allowance for loan losses associated with these loans. The lower the credit quality indicator, the lower the estimated expected cash flows and the greater the allowance recorded. All TDRs are individually evaluated for impairment through review of collateral values or analysis of cash flows at least annually.

26

The following table provides a summary of total TDRs by accrual status. Total TDRs included $18.0 million and $18.2 million of PCI TDRs at June 30, 2019 and December 31, 2018, respectively:

At June 30, 2019 and December 31, 2018, BancShares had $17.7 million and $17.2 million, respectively, of foreclosed residential real estate property in OREO. The recorded investment in consumer mortgage loans collateralized by residential real estate property in the process of foreclosure was $22.8 million and $22.0 million at June 30, 2019 and December 31, 2018, respectively.

NOTE G - FDIC SHARED-LOSS PAYABLE

As of June 30, 2019, shared-loss protection remains for single family residential loans acquired in the amount of $50.2 million. The shared-loss agreements for two FDIC-assisted transactions include provisions related to payments that may be owed to the FDIC at the termination of the agreements (clawback liability). The clawback liability represents a payment by BancShares to the FDIC if actual cumulative losses on acquired covered assets are lower than the cumulative losses originally estimated by the FDIC at the time of acquisition and is recorded in the Consolidated Balance Sheets as a payable to the FDIC under the relevant shared-loss agreements. The clawback liability payment dates are March 2020 and March 2021.

The following table provides changes in the FDIC shared-loss payable since December 31, 2018:

(Dollars in thousands)	Total

NOTE H - SERVICING RIGHTS

Mortgage Servicing Rights

Our portfolio of residential mortgage loans serviced for third parties was $3.01 billion and $2.95 billion as of June 30, 2019 and December 31, 2018, respectively. These loans are originated by BancShares and sold to third parties on a non-recourse basis with servicing rights retained. The retained servicing rights were recorded as a servicing asset and reported in other intangible assets on the Consolidated Balance Sheets, and the associated amortization expense and any valuation allowance recognized was included as a reduction of mortgage income in the Consolidated Statements of Income. The mortgage servicing rights were initially recorded at fair value and then carried at the lower of amortized cost or fair value.

Contractually specified mortgage servicing fees, late fees, and ancillary fees earned for the three months ended June 30, 2019 and 2018 were $2.0 million and $1.9 million, respectively, and reported in mortgage income in the Consolidated Statements of Income. For the six months ended June 30, 2019 and 2018, contractually specified mortgage servicing fees, late fees, and ancillary fees earned were $3.9 million and $3.8 million, respectively.

28

The following table explains changes in the servicing asset during the three and six months ended June 30, 2019 and 2018:

	Three months ended June 30						Six months ended June 30
(Dollars in thousands)	2019			2018			2019			2018
Beginning balance	$	20,647		$	21,659		$	21,396		$	21,945
Servicing rights originated	1,552			1,430			2,411			2,630
Amortization	(1,567		)	(1,432		)	(3,014		)	(2,918		)
Valuation allowance credit (provision)	33			—			(128		)	—
Ending balance	$	20,665		$	21,657		$	20,665		$	21,657

BancShares released $33.0 thousand of the valuation allowance for the three months ended June 30, 2019 and recorded provision expense of $128.0 thousand for the six months ended June 30, 2019. There was no valuation allowance provision expense or release recorded for the the three and six months ended June 30, 2018. Mortgage servicing rights valuations are performed using a pooling methodology where similar loans are grouped together and evaluated using discounted cash flows to estimate the present value of future earnings. Key economic assumptions used to value mortgage servicing rights were as follows:

	June 30, 2019			December 31, 2018
Discount rate - conventional fixed loans	9.01		%	9.69		%
Discount rate - all loans excluding conventional fixed loans	10.01		%	10.69		%
Weighted average constant prepayment rate	13.39		%	9.26		%
Weighted average cost to service a loan	$	88.03		$	87.52

The fair value of mortgage servicing rights is sensitive to changes in assumptions and is determined by estimating the present value of the asset's future cash flows by utilizing discount rates, prepayment rates, and other inputs. The discount rate is based on the 10-year U.S. Treasury rate plus 700 basis points for conventional fixed loans and 800 basis points for all other loans. The 700 and 800 basis points were used as a risk premium when calculating the discount rate. The prepayment rate is derived from the Public Securities Association Standard Prepayment model. Generally, as interest rates decline, mortgage loan prepayments accelerate due to increased refinance activity. This results in a decrease in fair value. The average cost to service a loan is based on the number of loans serviced and the total costs to service the loans.

Other Servicing Rights

Other servicing rights were acquired as part of a business combination and relate to the sale of the guaranteed portion of government guaranteed loans with servicing retained. The amount of the other servicing rights were $2.1 million and $2.7 million at June 30, 2019 and December 31, 2018, respectively.

NOTE I - REPURCHASE AGREEMENTS

BancShares, through FCB, utilizes securities sold under customer repurchase agreements to facilitate the needs of customers and secure wholesale funding needs. Repurchase agreements are transactions whereby FCB offers to sell to a counterparty an undivided interest in an eligible security, and which obligates FCB to repurchase the security, with interest, at an agreed upon date, repurchase price, and interest rate. These agreements are recorded at the amount of cash received in connection with the transaction and are reflected as securities sold under customer repurchase agreements on the Consolidated Balance Sheets.

Repurchase agreements require FCB to maintain collateral to support the outstanding obligations. BancShares monitors collateral levels on a continuous basis and maintains records of each transaction specifically describing the applicable security and the counterparty’s fractional interest in that security, and segregates the security from general assets in accordance with regulations governing custodial holdings of securities. The primary risk with repurchase agreements is market risk associated with the investments securing the transactions, as additional collateral may be required based on fair value changes of the underlying investments. Securities pledged as collateral under repurchase agreements are maintained with safekeeping agents and consist of U.S. Treasury securities. The carrying value of investment securities pledged as collateral under repurchase agreements was $612.5 million and $598.6 million at June 30, 2019 and December 31, 2018, respectively.

The remaining contractual maturity of the $544.5 million and $543.9 million securities sold under repurchase agreements at June 30, 2019 and December 31, 2018, respectively, was overnight and continuous.

NOTE J - ESTIMATED FAIR VALUES

Fair value estimates are intended to represent the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. Where there is no active market for a financial instrument, BancShares has made estimates using discounted cash flows or other valuation techniques. Inputs used in these valuation techniques are subjective in nature, involve uncertainties and require significant judgment and therefore can only be derived within a range of precision. Accordingly, the derived fair value estimates presented below are not necessarily indicative of the amounts BancShares would realize in a current market exchange.

ASC 820, Fair Value Measurements and Disclosures, indicates that assets and liabilities are recorded at fair value according to a fair value hierarchy comprised of three levels. The levels are based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. The level within the fair value hierarchy for an asset or liability is based on the highest level of input that is significant to the fair value measurement (with Level 1 considered highest and Level 3 considered lowest). A brief description of each level follows:

• Level 1 values are based on quoted prices for identical instruments in active markets.

• Level 2 values are based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market.

• Level 3 values are derived from valuation techniques in which one or more significant inputs or assumptions are not observable in the market. These unobservable inputs and assumptions reflect estimates that market participants would use in pricing the asset or liability. Valuation techniques include the use of discounted cash flow models and similar techniques.

BancShares' management reviews any changes to its valuation methodologies to ensure they are appropriate and supportable, and refines valuation methodologies as more market-based data becomes available. Transfers between levels of the fair value hierarchy are recognized at the end of the reporting period.

The methodologies used to estimate the fair value of financial assets and financial liabilities are discussed below:

Investment securities available for sale. Investment securities available for sale are carried at fair value. U.S. Treasury, government agency and mortgage-backed securities are generally measured at fair value using a third party pricing service. The third party provider evaluates securities based on comparable investments with trades and market data and will utilize pricing models that use a variety of inputs, such as benchmark yields, reported trades, broker-dealer quotes, issuer spreads, benchmark securities, bids and offers as needed. These securities are generally classified as Level 2. Corporate bonds and trust preferred securities are generally measured at fair value based on indicative bids from broker-dealers and are not directly observable. These securities are considered Level 3.

Investment in marketable equity securities. Equity securities are measured at fair value using observable closing prices and the valuation also considers the amount of market activity by examining the trade volume of each security. Equity securities are classified as Level 1 if they are traded in an active market and as Level 2 if the observable closing price is from a less than active market.

Loans held for sale. Certain residential real estate loans that are originated to be sold to investors are carried at fair value based on quoted market prices for similar types of loans. Accordingly, the inputs used to calculate fair value of originated residential real estate loans held for sale are classified as Level 2 inputs. Portfolio loans that are subsequently transferred to held for sale to be sold in the secondary market are carried at fair value when a firm commitment from a counterparty exists. The fair value of the transferred portfolio loans is based on the quoted prices and is considered a Level 1 input.

Net loans and leases (PCI and Non-PCI). Fair value is estimated based on discounted future cash flows using the current interest rates at which loans with similar terms would be made to borrowers of similar credit quality. The inputs used in the fair value measurements for loans and leases are considered Level 3 inputs.

FHLB stock. The carrying amount of FHLB stock is a reasonable estimate of fair value as these securities are not readily marketable and are evaluated for impairment based on the ultimate recoverability of the par value. BancShares considers positive and negative evidence, including the profitability and asset quality of the issuer, dividend payment history and recent redemption experience, when determining the ultimate recoverability of the par value. BancShares believes its investment in FHLB stock is ultimately recoverable at par. The inputs used in the fair value measurement for the FHLB stock are considered Level 2 inputs.

30

Mortgage and other servicing rights. Mortgage and other servicing rights are carried at the lower of amortized cost or market and are, therefore, carried at fair value only when fair value is less than the amortized cost. The fair value of mortgage and other servicing rights is performed using a pooling methodology. Similar loans are pooled together and a model that relies on discount rates, estimates of prepayment rates and the weighted average cost to service the loans is used to determine the fair value. The inputs used in the fair value measurement for mortgage and other servicing rights are considered Level 3 inputs.

Deposits. For non-time deposits, carrying value is a reasonable estimate of fair value. The fair value of time deposits is estimated by discounting future cash flows using the interest rates currently offered for deposits of similar remaining maturities. The inputs used in the fair value measurement for deposits are considered Level 2 inputs.    

Borrowings. For borrowings, the fair values are determined based on recent trades or sales of the actual security if available, otherwise, fair values are estimated by discounting future cash flows using current interest rates for similar financial instruments. The inputs used in the fair value measurement for long-term borrowings are considered Level 2 inputs.

Payable to the FDIC for shared-loss agreements. The fair value of the payable to the FDIC for shared-loss agreements is determined by the projected cash flows based on expected payments to the FDIC in accordance with the shared-loss agreements. Cash flows are discounted using current discount rates to reflect the timing of the estimated amounts due to the FDIC. The inputs used in the fair value measurement for the payable to the FDIC are considered Level 3 inputs.

Off-balance-sheet commitments and contingencies. Carrying amounts are reasonable estimates of the fair values for such financial instruments. Carrying amounts include unamortized fee income and, in some cases, reserves for any credit losses from those financial instruments. These amounts are not material to BancShares' financial position.

 For all other financial assets and financial liabilities, the carrying value is a reasonable estimate of the fair value as of June 30, 2019 and December 31, 2018. The carrying value and fair value for these assets and liabilities are equivalent because they are relatively short term in nature and there is no interest rate or credit risk that would cause the fair value to differ from the carrying value. Cash and due from banks is classified on the fair value hierarchy as Level 1. Overnight investments, income earned not collected, securities sold under customer repurchase agreements, and accrued interest payable are considered Level 2.

The table presents the carrying values and estimated fair values for financial instruments as of June 30, 2019 and December 31, 2018:

During the three and six months ended June 30, 2019, there were no transfers between levels. For the three months ended June 30, 2018, there were no transfers between levels and for the six ended June 30, 2018, there were transfers from Level 2 to Level 3 of $65.3 million for corporate bonds available for sale. The transfers were due to a lack of observable inputs and trade activity for those securities.

Fair Value Option

BancShares has elected the fair value option for residential real estate loans originated to be sold. This election reduces certain timing differences in the Consolidated Statement of Income and better aligns with the management of the portfolio from a business perspective. The changes in fair value were recorded as a component of mortgage income and included a loss of $82 thousand and a gain of $700 thousand for the three months ended June 30, 2019 and June 30, 2018, respectively. The changes in fair value included a gain of $167 thousand and $245 thousand for six months ended June 30, 2019 and June 30, 2018, respectively.

The following table summarizes the difference between the aggregate fair value and the aggregate unpaid principal balance for residential real estate originated for sale measured at fair value as of June 30, 2019 and December 31, 2018:

	June 30, 2019
(Dollars in thousands)	Fair Value		Aggregate Unpaid Principal Balance		Difference
Originated loans held for sale	$	52,837	$	51,237	$	1,600
	December 31, 2018
	Fair Value		Aggregate Unpaid Principal Balance		Difference
Originated loans held for sale	$	45,505	$	44,073	$	1,432

No originated loans held for sale were 90 or more days past due or on nonaccrual status as of June 30, 2019 or December 31, 2018.

We may be required to measure certain financial assets at fair value on a nonrecurring basis. These adjustments to fair value usually result from the application of lower of amortized cost or fair value accounting or write-downs of individual assets due to impairment.

Impaired loans are deemed to be at fair value if an associated allowance or current period charge-off has been recorded. The value of impaired loans is determined by either collateral valuations or discounted present value of the expected cash flow calculations. Collateral values are determined using appraisals or other third-party value estimates of the subject property with discounts generally between 6% and 11% applied for estimated selling costs and other external factors that may impact the marketability of the property. Expected cash flows are determined using expected payment information at the individual loan level, discounted using the effective interest rate. The effective interest rate generally ranges between 2% and 18%.

OREO acquired or written down within the previous 12 months is deemed to be at fair value. Asset valuations are determined by using appraisals or other third-party value estimates of the subject property with discounts generally between 6% and 11% applied for estimated selling costs and other external factors that may impact the marketability of the property. Changes to the value of the assets between scheduled valuation dates are monitored through continued communication with brokers and monthly reviews by the asset manager assigned to each asset. If there are any significant changes in the market or the subject property, valuations are adjusted or new appraisals ordered to ensure the reported values reflect the most current information.

For financial assets and liabilities carried at fair value on a nonrecurring basis, the following table provides fair value information as of June 30, 2019 and December 31, 2018:

No discretionary contributions were made during the six months ended June 30, 2019 to the BancShares or Bancorporation pension plans. Management evaluates the need for its pension plan contributions on a periodic basis based upon numerous factors including, but not limited to, the funded status of the plans, returns on plan assets, discount rates and the current economic environment. BancShares made a contribution of $3.5 million to the Bancorporation plan in July 2019.

NOTE L - COMMITMENTS AND CONTINGENCIES

To meet the financing needs of its customers, BancShares and its subsidiaries have financial instruments with off-balance sheet risk. These financial instruments include commitments to extend credit and standby letters of credit. These instruments involve elements of credit, interest rate or liquidity risk.

Commitments to extend credit are legally binding agreements to lend to customers. Commitments generally have fixed expiration dates or other termination clauses and may require payment of fees. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future liquidity requirements. Established credit standards control the credit risk exposure associated with these commitments. In some cases, BancShares requires that collateral be pledged to secure the commitment, including cash deposits, securities and other assets.

Standby letters of credit are commitments guaranteeing performance of a customer to a third party. Those commitments are primarily issued to support public and private borrowing arrangements, and the fair value of those commitments was not material. To mitigate its risk, BancShares’ credit policies govern the issuance of standby letters of credit. The credit risk related to the issuance of these letters of credit is essentially the same as that involved in extending loans to clients and, therefore, these letters of credit are collateralized when necessary.

The following table presents the commitments to extend credit and unfunded commitments as of June 30, 2019 and December 31, 2018:

(Dollars in thousands)	June 30, 2019		December 31, 2018
Unused commitments to extend credit	$	10,348,284	$	10,054,712
Standby letters of credit	94,307		96,467
Unfunded commitments for investments in affordable housing projects	80,383		67,952

Affordable housing project investments were $170.3 million and $147.3 million as of June 30, 2019 and December 31, 2018, respectively, and were included in other assets on the Consolidated Balance Sheets.

34

BancShares and various subsidiaries have been named as defendants in legal actions arising from their normal business activities in which damages in various amounts were claimed. BancShares has also been exposed to litigation risk relating to the prior business activities of banks from which assets were acquired and liabilities assumed in the various merger transactions. Although the amount of any ultimate liability with respect to such matters cannot be determined, in the opinion of management, any such liability will not have a material effect on BancShares’ consolidated financial statements.

NOTE N - LEASES

BancShares leases certain branch locations, administrative offices and equipment. Operating lease ROU assets are included in other assets and the associated lease obligations are included in other liabilities on the Consolidated Balance Sheets. Finance leases are included in premises and equipment and other borrowings on the Consolidated Balance Sheets. Leases with an initial term of 12 months or less are not recorded on the Consolidated Balance Sheets; we instead recognize lease expense for these leases on a straight-line basis over the lease term.

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our corresponding obligation to make lease payments arising from the lease. Operating and finance lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. The operating and finance lease ROU asset also includes initial direct costs and pre-paid lease payments made, excluding lease incentives. As most of our leases do not provide an implicit rate, BancShares uses its incremental borrowing rate, based on the information available at commencement date in determining the present value of lease payments. The incremental borrowing rate is determined using secured rates for new FHLB advances under similar terms as the lease at inception. BancShares used the incremental borrowing rate on January 1, 2019, for operating leases that commenced prior to that date.

Most leases include one or more options to renew, with renewal terms that can extend the lease term from 1 to 25 years. The exercise of lease renewal options is at our sole discretion. When it is reasonably certain that we will exercise our option to renew or extend the lease term, that option is included in calculating the value of the ROU and lease liability. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise.

We determine if an arrangement is a lease at inception and our lease agreements do not contain any material residual value guarantees or material restrictive covenants. We have no related party lease agreements. As of June 30, 2019, there were no leases that have not yet commenced that would have a material impact on our Consolidated Financial Statements.

We rent or sublease certain real estate to third parties to manage occupancy costs and provide flexibility to expand and contract occupancy space to meet our business needs.

The following table presents lease costs for the three and six months ended June 30, 2019. Variable lease cost primarily represents variable payments such as common area maintenance and utilities that are recognized in the period in which the expense was incurred. Certain of our lease agreements also include rental payments that are adjusted periodically for inflation. While lease liabilities are not remeasured as a result of these changes, these adjustments are treated as a variable lease costs and recognized in the period in which the expense is incurred.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Management’s discussion and analysis (MD&A) of earnings and related financial data are presented to assist in understanding the financial condition and results of operations of First Citizens BancShares, Inc. and Subsidiaries (BancShares). This discussion and analysis should be read in conjunction with the unaudited consolidated financial statements and related notes presented within this report along with our financial statements and related MD&A of financial condition and results of operations included in our 2018 Annual Report on Form 10-K. Intercompany accounts and transactions have been eliminated. Although certain amounts for prior years have been reclassified to conform to statement presentations for 2019, the reclassifications had no effect on shareholders’ equity or net income as previously reported. Unless otherwise noted, the terms “we,” “us” and “BancShares” refer to the consolidated financial position and consolidated results of operations for BancShares.

EXECUTIVE OVERVIEW

BancShares conducts its banking operations through its wholly-owned subsidiary First-Citizens Bank & Trust Company (FCB), a state-chartered bank organized under the laws of the state of North Carolina.

BancShares’ earnings and cash flows are primarily derived from our commercial and retail banking activities. We gather deposits from retail and commercial customers and also secure funding through various non-deposit sources. We invest the liquidity generated from these funding sources in interest-earning assets, including loans and leases, investment securities and overnight investments. We also invest in bank premises, hardware, software, furniture and equipment used to conduct our commercial and retail banking business. We provide treasury services products, cardholder and merchant services, wealth management services and various other products and services typically offered by commercial banks. The fees and service charges generated from these products and services are primary sources of noninterest income which is an essential component of our total revenue.

We are focused on expanding our position in legacy and target markets through organic growth and strategic acquisitions. We believe that our franchise is positioned for continued growth as a result of our client centric banking principles, disciplined lending standards, and our people. Management's primary focus is on loan and yield growth, deposit cost, and net interest margin. Management drives to this goal by focusing on core customer deposits and loans in the targeted interest rate risk profile. Additionally, our initiatives focus on growth of noninterest income sources, control of noninterest expenses, optimization of our branch network, and further enhancements to our technology and delivery channels. Refer to our Form 10-K for the year ended December 31, 2018 for further discussion of our strategy.

Significant Events in 2019

On April 23, 2019, FCB entered into a definitive merger agreement for the acquisition of Franklin, North Carolina-based Entegra Financial Corp. and its bank subsidiary, Entegra Bank, into FCB.

On May 1, 2019, FCB completed the merger of Spartanburg, South Carolina-based First South Bancorp and its bank subsidiary, First South Bank, into FCB.

On April 2, 2019, FCB completed the merger of Coconut Grove, Florida-based Biscayne Bancshares and its bank subsidiary, Biscayne Bank, into FCB.

RECENT ECONOMIC AND INDUSTRY DEVELOPMENTS

Various external factors influence the focus of our business efforts and the results of our operations can change significantly based on those external factors. Based on the latest real gross domestic product (GDP) information available, the Bureau of Economic Analysis' revised estimate of first quarter of 2019 GDP growth was 3.1%, up from 2.2% GDP growth in the fourth quarter of 2018. The estimated real GDP acceleration in the first quarter primarily reflected an upturn in state and local government spending, accelerations in private inventory investment and an increase in exports. Imports decreased in the first quarter of 2019 after increasing in the fourth quarter of 2018. These movements were partly offset by a deceleration in personal consumption expenditures.

The United States (U.S.) unemployment rate declined from 3.8% in March 2019 to 3.7% in June 2019. According to the U.S. Department of Labor, the U.S. economy added approximately 512,000 new nonfarm payroll jobs during the second quarter of 2019. The U.S. housing market remains stable as a result of strong, but weakening, housing demand fueled by low mortgage interest rates, economic growth and job creation.

The Federal Reserve’s Federal Open Market Committee (FOMC) indicated in July 2019 the U.S. labor market remains strong and economic activity rose at a moderate rate. In light of the implications of global developments for the economic outlook as well as muted inflation pressures, the FOMC decided to lower the target range for the federal funds rate by 25 basis points to 2.00% to 2.25%. In determining the timing and size of future adjustments to the target range for the federal funds rates, the FOMC indicated it will assess realized and expected economic conditions relative to its objectives of maximum employment and 2.0% inflation.

RESULTS OF OPERATIONS

Net Interest Income and Margin (Taxable-Equivalent Basis)

Second Quarter 2019 compared to Second Quarter 2018

Net interest income for the second quarter of 2019 totaled $327.3 million, an increase of $31.1 million, or 10.5%, compared to the second quarter of 2018. The taxable-equivalent NIM was 3.79% in the second quarter of 2019, an increase of 15 basis points from the same quarter in the prior year. The primary driver for this increase was a $42.1 million, or 24 basis points increase in interest and fees on loans due to higher average loans outstanding and higher loan yields, partially offset by a $14.6 million, or 30 basis points increase in interest expense on deposits due to higher balances and rates paid on time deposits and money market accounts.

Average interest-earning assets increased by $2.01 billion to $34.67 billion, compared to the second quarter of 2018. The primary driver for this change was higher average loan balances which increased $2.39 billion, primarily due to contributions from recent acquisitions and organic loan growth particularly within the commercial and residential mortgage portfolios. Offsetting this increase were declines in average investment securities of $287.9 million and average overnight investments of $99.0 million. The yield on interest-earning assets increased by 31 basis points to 4.06% when compared to the second quarter of 2018. The yield on loans and leases increased to 4.58%, or by 24 basis points, primarily due to higher yields on commercial and residential loans. The yield on overnight investments and investment securities increased by 65 basis points and 27 basis points, respectively. Higher federal funds rates was the primary driver for the yield increase on overnight investments, while the higher yields on mortgage-backed securities and U.S. Treasury securities were the primary drivers of the investment securities yield improvement.

Average interest-bearing liabilities increased $1.51 billion to $20.40 billion, compared to the second quarter of 2018. This increase was primarily due to an increase in average interest-bearing deposit balances of $1.34 billion driven by contributions from recent acquisitions and organic deposit growth, an increase in average long-term borrowings of $138.5 million, and an increase in average customer repurchase agreements of $39.4 million. Rates on interest-bearing liabilities increased by 30 basis points to 0.46%, primarily due to increased rates paid on time deposits and money market accounts.

47

Six Months of 2019 compared to Six Months of 2018

Net interest income for the six months ended June 30, 2019, was $647.8 million, an increase of $67.2 million, or 11.6%, compared to the same period of 2018. The taxable-equivalent NIM was 3.84% for the six months ended June 30, 2019, an increase of 23 basis points, from the same period of 2018. The primary driver of the increase was an $81.1 million, or 27 basis points increase in interest and fees on loans due to an increase in average loans outstanding, as well as higher loan yields. This increase was partially offset by a $23.8 million, or 25 basis points increase in interest expense on deposits.

Average year-to-date interest-earning assets for the six months ended June 30, 2019, increased by $1.56 billion to $34.06 billion, compared to the same period in 2018. This increase was primarily due to a $2.12 billion increase in average outstanding loans due the impact of recent acquisitions and organic loan growth, particularly within the commercial and residential mortgage portfolios. These increases were partially offset by declines in average overnight investments of $286.9 million and average investment securities of $274.7 million. The yield on interest-earning assets increased by 37 basis points to 4.07% for the six months ended June 30, 2019, compared to the same period in 2018. The yield on loans and leases increased by 27 basis points primarily due to higher yielding commercial and residential loans. The yield on overnight investments and the investment securities portfolio increased by 78 basis points and 31 basis points, respectively. Higher federal funds rates was the primary driver for the yield increase on overnight investments, while the higher yields on mortgage-backed securities and U.S. Treasury securities were the primary drivers of the investment securities yield improvement.

Average year-to-date interest-bearing liabilities for the six months ended June 30, 2019 increased by $1.07 billion to $20.03 billion compared to the same period in 2018. This increase was primarily due to a $1.08 billion increase in average interest-bearing deposit balances driven by the impact of recent acquisitions, as well as organic growth, primarily in time deposits and money market accounts. The rate paid on interest-bearing liabilities increased by 23 basis points to 0.40% for the six months ended June 30, 2019 compared to same period in 2018. The rate paid on interest-bearing deposits increased by 25 basis points due primarily to increased rates on time deposits and money market accounts. Rates on long-term borrowings increased by 28 basis points due to higher rates on borrowings assumed in recent acquisitions.

Although net interest margin has expanded in recent periods, management does not believe this trend will continue as new loan yields are declining due to changes in forward rate expectations and increased competition. This trend, coupled with higher interest expense and rising betas on deposits will likely result in margin compression for the remainder of 2019.

Provision for Loan and Lease Losses

BancShares recorded net provision expense of $5.2 million and $16.9 million for the three and six months ended June 30, 2019 as compared to $8.4 million and $16.0 million, respectively, for the same periods in 2018. The fluctuations in provision expense were primarily due to variances in loan growth between the periods, as well as changes in portfolio composition and credit quality.

Noninterest income is an essential component of our total revenue and is critical to our ability to sustain adequate profitability levels. The primary sources of noninterest income consist of fees and service charges generated from deposit accounts, cardholder and merchant services, wealth management services, and mortgage lending and servicing.

Noninterest income for the second quarter of 2019 was $106.9 million, compared to $100.9 million for the same period of 2018, an increase of $5.9 million, or 5.9%. The most significant components of the change were as follows:

• Realized gains on investment securities sales were $5.7 million for the second quarter of 2019, while no gains were recognized in the second quarter of 2018.

• Income from cardholder services increased by $3.6 million due to higher interchange rates and transaction volumes, as well as cost savings achieved by converting to a new processor.

• Fair value adjustments on marketable equity securities declined by $1.3 million.

Noninterest income was $210.5 million for the first six months of 2019, compared to $223.6 million for the same period of 2018, a decrease of $13.1 million, or 1.31%. The most significant components of the change were as follows:

• $25.8 million gain on the extinguishment of debt in was recognized 2018, while no gains were recognized in 2019. The gain was primarily due to the extinguishment of eight Federal Home Loan Bank debt obligations totaling $675.0 million.

• Fair value adjustments on marketable equity securities increased by $9.1 million.

• Realized gains on investment securities sales were $5.7 million in 2019; no gains were recognized in 2018.

• Income from cardholder services increased by $5.4 million due to higher transaction volumes and interchange rates, as well as cost savings achieved by converting to a new processor.

• Service charges on deposit accounts and ATM income declined by $2.9 million due to reductions in acquired deposit balances and the temporary suspension of ATM fees at certain acquired locations.

• Recoveries on acquired loans previously charged-off decreased by $2.6 million.

Noninterest expense was $273.4 million during the second quarter of 2019, compared to $266.0 million for the same period in 2018, an increase of $7.4 million, or 2.8%. The most significant components of the change were as follows:

• Personnel expense increased $7.2 million primarily due to an increase in salaries and wages as a result of merit increases, and increased headcount from recent acquisitions.

• Equipment expense increased by $3.3 million primarily due to hardware and software additions.

• Merger-related expense increased by $1.7 million primarily due to an increase in acquisition activity.

49

• FDIC insurance expense decreased $2.7 million primarily due to the discontinuation of the Deposit Insurance Fund surcharge on large banks.

• Processing fees paid to third parties decreased by $1.2 million primarily due to cost savings associated with the operational conversion of previously completed acquisitions, partially offset by an increase in digital banking costs.

Noninterest expense was $541.1 million for the first six months of 2019, compared to $534.1 million for the same period in 2018, an increase of $7.0 million, or 1.3%. The most significant components of the change were as follows:

• Personnel expense increased $10.8 million primarily due to an increase in salaries and wages as a result of merit increases and increased headcount from recent acquisitions.

• Equipment expense increased by $5.1 million primarily due to hardware and software additions.

• Merger-related expense increased by $2.8 million primarily due to an increase in acquisition activity.

• FDIC insurance expense decreased $5.8 million primarily due to the discontinuation of the Deposit Insurance Fund surcharge on large banks.

• Processing fees paid to third parties decreased by $2.4 million primarily due to cost savings associated with the operational conversion of previously completed acquisitions, partially offset by an increase in digital banking costs.

• Collection and foreclosure-related expense decreased $1.4 million primarily due to reductions in the write downs of bank-owned properties.

Income Taxes

Income tax expense was $36.3 million and $29.4 million for the second quarter of 2019 and second quarter of 2018, respectively, representing effective tax rates of 23.3% and 24.0% during the periods. Income tax expense was $69.6 million and $60.6 million for the six months ended June 30, 2019 and June 30, 2018, respectively, representing effective tax rates of 23.2% and 23.9% for the six months periods.

We monitor and evaluate the potential impact of current events on the estimates used to establish income tax expenses and income tax liabilities. On a periodic basis, we evaluate our income tax positions based on current tax law, positions taken by various tax auditors within the jurisdictions where BancShares is required to file income tax returns, as well as potential or pending audits or assessments by tax auditors.

INTEREST-EARNING ASSETS

Interest-earning assets include investment securities, loans and leases, and overnight investments, all of which reflect varying interest rates based on the risk level and repricing characteristics of the underlying asset. Riskier investments typically carry a higher interest rate but expose us to higher levels of market risk. We strive to maintain a high level of interest-earning assets relative to total assets, while keeping non-earning assets at a minimum.

Interest-earning assets totaled $35.12 billion and $33.20 billion at June 30, 2019 and December 31, 2018, respectively. The $1.92 billion increase was primarily composed of a $1.20 billion increase in loans and leases and a $842.9 million increase in overnight investments, partially offset by a $138.8 million decrease in investment securities.

Investment Securities

The primary objective of the investment portfolio is to generate incremental income by deploying excess funds into securities that have minimal liquidity and credit risk, and low to moderate interest rate risk. Other objectives include acting as a stable source of liquidity, serving as a tool for asset and liability management and maintaining an interest rate risk profile compatible with BancShares' objectives. Additionally, purchases of equities and corporate bonds in other financial institutions have been made largely under a long-term earnings optimization strategy. Changes in the total balance of our investment securities portfolio result from trends in balance sheet funding and market performance. Generally, when inflows arising from deposit and treasury services products exceed loan and lease demand, we invest excess funds into the securities portfolio or into overnight investments. Conversely, when loan demand exceeds growth in deposits and short-term borrowings, we allow any overnight investments to decline and use proceeds from maturing securities and prepayments to fund loan demand. See Note C in the Consolidated Financial Statements for additional disclosures regarding investment securities.

Investment securities totaled $6.70 billion at June 30, 2019, a decrease of $138.8 million compared to December 31, 2018. The decrease in the portfolio was primarily attributable to investment securities maturities/paydowns of $1.40 billion and sales of $621.6 million only partially offset by purchases totaling $1.75 billion.

50

As of June 30, 2019, investment securities available for sale had a net pre-tax unrealized gain of $3.3 million, compared to a net pre-tax unrealized loss of $50.0 million as of December 31, 2018. After evaluating the available for sale securities with unrealized losses, management concluded that the unrealized losses relate to changes in interest rates relative to when the securities were purchased, and therefore, no other than temporary impairment existed as of June 30, 2019. Available for sale securities are reported at fair value and unrealized gains and losses were included as a component of AOCI, net of deferred taxes.

Loans and Leases

Loans and leases were $26.73 billion at June 30, 2019, a net increase of $1.20 billion, representing annualized growth of 9.5% since December 31, 2018. This increase was driven by a $1.26 billion net increase in the non-PCI portfolio, partially offset by a $55.1 million decline in the PCI loan portfolio. The net increase in the non-PCI portfolio was due to $1.01 billion in non-PCI loans acquired through the recent acquisitions of Biscayne Bancshares and First South Bancorp as well as organic growth primarily in the commercial mortgage and residential mortgage portfolios. Excluding acquired loans, total loans grew by 1.4% on an annualized basis.

BancShares reports non-PCI and PCI loan portfolios separately, and each portfolio is further divided into commercial and non-commercial. Non-PCI loans and leases at June 30, 2019 were $26.18 billion, representing 97.9% of total loans and leases, compared to $24.92 billion or 97.6% at December 31, 2018. PCI loans at June 30, 2019 were $551.4 million, representing 2.1% of total loans and leases, compared to $606.6 million or 2.4% at December 31, 2018.

The discount related to acquired non-PCI loans and leases at June 30, 2019 and December 31, 2018 was $35.7 million and $33.3 million, respectively. The discount related to PCI loans at June 30, 2019 and December 31, 2018 was $93.0 million and $95.5 million, respectively.

ALLOWANCE FOR LOAN AND LEASE LOSSES (ALLL)

The allowance for loan and lease losses was $226.6 million at June 30, 2019, representing an increase of $2.9 million since December 31, 2018. The ALLL as a percentage of total loans and leases was 0.85% at June 30, 2019, compared to 0.88% December 31, 2018.

At June 30, 2019, the ALLL allocated to total non-PCI loans and leases was $218.2 million, or 0.83% of non-PCI loans and leases, compared to $214.6 million, or 0.86%, at December 31, 2018. The ALLL as a percentage of non-PCI loans and leases declined 0.03% since December 31, 2018 primarily due to changes in portfolio mix partially offset by credit quality declines and increases in specific reserves.

At June 30, 2019, the ALLL for PCI loans totaled $8.3 million compared to $9.1 million at December 31, 2018. The decrease was primarily due to continued PCI loan portfolio run-off and improving cash flow estimates.

Net charge-offs for non-PCI loans and leases were $7.4 million during the second quarter of 2019, compared to $6.7 million during the second quarter of 2018. On an annualized basis, total net charge-offs as a percentage of total average loans and leases was 0.11% for the second quarter of 2019 and the second quarter of 2018. The net charge-off ratio was 0.11% for the six months ended June 30, 2019, unchanged for the same period of 2018.

NONPERFORMING ASSETS

Nonperforming assets include nonaccrual loans and leases and other real estate owned (OREO). At June 30, 2019, BancShares’ nonperforming assets totaled $151.2 million, an increase of $17.4 million since December 31, 2018.

Nonaccrual loans and leases at June 30, 2019 were $105.0 million, reflecting an increase of $19.2 million since December 31, 2018. The increase was primarily due to new nonaccrual loans within the commercial mortgage portfolio and acquired nonaccrual loans totaling $7.9 million. Despite this increase, the credit quality of the portfolio remains in line with our risk tolerances and management has not identified significant increases in portfolio risk. At June 30, 2019, OREO totaled $46.2 million, representing a decline of $1.8 million since December 31, 2018 as sales and write-downs of assets outpaced additions.

TROUBLED DEBT RESTRUCTURINGS (TDRs)

We selectively agree to modify existing loan terms to provide relief to customers who are experiencing financial difficulties or other circumstances that could affect their ability to meet debt obligations. Typical modifications include short-term deferral of interest or modification of payment terms. TDRs that were not accruing interest at the time of restructure are included as nonperforming loans. TDRs that were accruing at the time of restructure and continue to perform based on the restructured terms are considered performing loans. Loans acquired under ASC 310-30 (PCI Loans), excluding pooled loans, are not initially considered to be TDRs, but can be classified as such if a modification is made subsequent to acquisition. Subsequent modification of a PCI loan accounted for in a pool that would otherwise meet the definition of a TDR is not reported, or accounted for, as a TDR since pooled PCI loans are excluded from the scope of TDR accounting.

OTHER ASSETS

Other assets increased $305.8 million primarily due an increase in accounts receivable of $152.3 million mainly driven by outstanding proceeds from unsettled U.S. Treasury securities maturities, as well as the addition of new operating lease right-of-use assets totaling $81.5 million and additional BOLI assets totaling $32.6 million obtained in recent acquisitions.

INTEREST-BEARING LIABILITIES

Interest-bearing liabilities include interest-bearing deposits, securities sold under customer repurchase agreements, federal funds purchased, FHLB borrowings, subordinated debentures, and other borrowings. Interest-bearing liabilities totaled $20.68 billion at June 30, 2019, compared to $19.68 billion at December 31, 2018. The $1.00 billion increase was due an increase in interest-bearing deposits of $979.5 million, an increase in subordinated debentures of $13.5 million.

Deposits

Due to our focus on maintaining a strong liquidity position, core deposit retention remains a key business objective. We believe that traditional bank deposit products remain an attractive option for many customers but, as economic conditions improve, we recognize that our liquidity position could be adversely affected as bank deposits are withdrawn and invested elsewhere. Our ability to fund future loan growth is significantly dependent on our success at retaining existing deposits and generating new deposits at a reasonable cost.

At June 30, 2019, total deposits were $32.72 billion, an increase of $2.05 billion, representing annualized growth of 13.5% since December 31, 2018. Excluding acquired deposits totaling $1.04 billion, total deposits increased $1.01 billion, or by 6.6% annualized, over the same time period. This organic growth was primarily the result of increases in demand, interest checking and time deposit accounts, partially offset by a decline in money market accounts.

BancShares owns five special purpose entities – FCB/NC Capital Trust III, FCB/SC Capital Trust II, SCB Capital Trust I, CCBI Capital Trust I, and FSBS Capital Trust I (the Trusts), which mature in 2036, 2034, 2034, 2036, and 2034, respectively. Subordinated debentures included junior subordinated debentures representing obligations to the Trusts, which may be redeemed at par in whole or in part at any time. BancShares has guaranteed all obligations of the Trusts.

During the six months ended June 30, 2019, FCB redeemed, in whole, all obligations related to CCBI Capital Trust I. In July 2019, FCB redeemed, in whole, all obligations related to FSBS Capital Trust I.

SHAREHOLDERS' EQUITY AND CAPITAL ADEQUACY

Table 15 shows activities that caused the change in outstanding Class A common stock over the past five quarters.

In October 2018, BancShares' Board of Directors authorized the repurchase of up to 800,000 of BancShares' Class A common stock for the period November 1, 2018 through October 31, 2019. The authorization does not obligate BancShares to repurchase any particular amount of shares, and repurchases may be suspended or discontinued at any time. During the second quarter of 2019, BancShares repurchased 205,500 shares of Class A common stock for $89.8 million at an average cost per share of $436.81. During the first six months of 2019, BancShares repurchased a total of 448,500 shares of Class A common stock for $190.5 million at an average cost per share of $424.77. As of June 30, 2019, a total of 630,500 shares have been repurchased under the current Board authority. There were no share repurchases made during the comparable periods in 2018.

In April 2019, the Board authorized the repurchase of up to 800,000 of BancShares' Class A common stock for the period July 1, 2019 through June 30, 2020. This authorization was effective July 1, 2019 and supersedes the authorization approved in October 2018. Under this authorization and subsequent to quarter-end through August 2, 2019, BancShares repurchased an additional 69,600 shares of Class A common stock for $31.7 million at an average cost per share of $455.94.

We are committed to effectively managing our capital to protect our depositors, creditors and shareholders. We continually monitor the capital levels and ratios for BancShares and FCB to ensure they exceed the minimum requirements imposed by regulatory authorities and to ensure they are appropriate given growth projections, risk profile and potential changes in the regulatory or external environment. Failure to meet certain capital requirements may result in actions by regulatory agencies that could have a material impact on our consolidated financial statements.

56

In accordance with accounting principles generally accepted in the United States of America (GAAP), the unrealized gains and losses on certain assets and liabilities, net of deferred taxes, are included in accumulated other comprehensive loss within shareholders' equity. These amounts are excluded from shareholders' equity in the calculation of our capital ratios under current regulatory guidelines.

As of June 30, 2019, BancShares and FCB continued to exceed minimum capital standards and remained well-capitalized under Basel III guidelines. Trust preferred capital securities continue to be a component of total risk-based capital.

The capital conservation buffer introduced under Basel III became fully phased in at January 1, 2019 at 2.50%. BancShares and FCB had capital conservation buffers of 5.34% and 5.10%, respectively, at June 30, 2019, which exceeded the 2.50% requirement and, therefore, result in no limit on distributions.

RISK MANAGEMENT

Risk is inherent in any business. BancShares has defined a moderate risk appetite, a conservative approach to risk taking, with a philosophy that does not preclude higher risk business activities balanced with acceptable returns while meeting regulatory objectives. Through the comprehensive Enterprise Risk Management Framework and Risk Appetite Framework, senior management has primary responsibility for day-to-day management of the risks we face with accountability of and support from all associates. Senior management applies various strategies to reduce the risks to which BancShares activities may be exposed, with effective challenge and oversight by management committees. In addition, the Board of Directors strives to ensure that the business culture is integrated with the enterprise risk management program and that policies, procedures and metrics for identifying, assessing, measuring, monitoring and managing risk are part of the decision-making process. The Board of Directors’ role in risk oversight is an integral part of our overall Enterprise Risk Management Framework and Risk Appetite Framework.  The Board of Directors administers its risk oversight function primarily through the Board Risk Committee.

The Board Risk Committee structure is designed to allow for information flow, effective challenge and timely escalation of risk-related issues. The Board Risk Committee is directed to monitor and advise the Board of Directors regarding risk exposures, including credit, market, capital, liquidity, operational, compliance, strategic and reputational risks; review, approve, and monitor adherence to the risk appetite and supporting risk tolerance levels via a series of established metrics; and evaluate, monitor and oversee the adequacy and effectiveness of the Risk Management Framework and Risk Appetite Framework. The Board Risk Committee also reviews: reports of examination by and communications from regulatory agencies; the results of internal and third party testing and qualitative and quantitative assessments related to risk management; and any other matters within the scope of the Committee’s oversight responsibilities. The Board Risk Committee monitors management's response to certain risk-related regulatory and audit issues. In addition, the Board Risk Committee may coordinate with the Audit Committee and the Compensation, Nominations and Governance Committee for the review of financial statements and related risks, information security and other areas of joint responsibility.

In combination with other risk management and monitoring practices, enterprise-wide stress testing activities are part of the Risk Management Framework and conducted within a defined framework. Stress tests are performed for various risks to ensure the financial institution can support continued operations during stressed periods.

57

Credit risk management

Credit risk is the risk of not collecting payments pursuant to the contractual terms of loans, leases and certain investment securities. Loans and leases we originate are underwritten in accordance with our credit policies and procedures and are subject to periodic ongoing reviews. Acquired loans, regardless of whether PCI or non-PCI, are recorded at fair value as of the acquisition date and are subject to periodic reviews to identify any further credit deterioration. Our independent credit review function conducts risk reviews and analyses of both originated and acquired loans to ensure compliance with credit policies and to monitor asset quality trends and borrower financial strength. These reviews include portfolio analysis by geographic location, industry, collateral type and product. We strive to identify potential problem loans as early as possible, to record charge-offs or write-downs as appropriate and to maintain an adequate ALLL that accounts for losses that are inherent in the loan and lease portfolio.

Interest rate risk management

Interest rate risk (IRR) results principally from: assets and liabilities maturing or repricing at different points in time, assets and liabilities repricing at the same point in time but in different amounts, and short-term and long-term interest rates changing in different magnitudes.

We assess our short-term IRR by forecasting net interest income over 24 months under various interest rate scenarios and comparing those results to forecasted net interest income, assuming stable rates. IRR scenarios modeled, include, but are not limited to, immediate, parallel rate shocks, interest rate ramps, changes in the shape of the yield curve and changes in the relationships of our rates to market rates. While market interest rates peaked in November 2018, interest-bearing deposit rates have continued to see upward pressure due to rate specials and acquisitions. Despite this trend, overall rates remain relatively low and, as such, it is unlikely these rates will decline materially from current levels. Additionally, our projections incorporate an internal rate outlook and assumptions of customer migration from low rate deposit instruments to intermediate term fixed rate instruments as rates rise.

Table 17 provides the impact on net interest income over 24 months resulting from various instantaneous interest rate shock scenarios as of June 30, 2019 and December 31, 2018.

Table 17

NET INTEREST INCOME SENSITIVITY ANALYSIS

	Estimated percentage increase (decrease) in net interest income
Change in interest rate (basis points)	June 30, 2019		December 31, 2018
-100	(11.18	)%	(10.67	)%
+100	3.66		2.38
+200	4.49		1.66

Net interest income sensitivity metrics at June 30, 2019 compared to December 31, 2018 were primarily affected by a reduction in the forecast for both the number of offerings and promotional rates paid on time deposits. Additionally, as market interest rates have continued to fall throughout 2019, prepayment speeds have increased leading to an increase in loan interest income under positive rate shocks.

Long-term interest rate risk exposure is measured using the economic value of equity (EVE) sensitivity analysis to study the impact of long-term cash flows on earnings and capital. EVE represents the difference between the sum of the present value of all asset cash flows and the sum of the present value of the liability cash flows. EVE sensitivity analysis involves discounting cash flows of balance sheet items under different interest rate scenarios. Cash flows will vary by interest rate scenario, resulting in variations in EVE. The base-case measurement and its sensitivity to shifts in the yield curve allow management to measure longer-term repricing and option risk in the balance sheet.

Table 18 table presents the EVE profile as of June 30, 2019 and December 31, 2018.

Table 18

ECONOMIC VALUE OF EQUITY MODELING ANALYSIS

	Estimated percentage increase (decrease) in EVE
Change in interest rate (basis points)	June 30, 2019		December 31, 2018
-100	(21.14	)%	(15.14	)%
+100	10.24		3.34
+200	12.20		1.40

The economic value of equity metrics at June 30, 2019 compared to December 31, 2018 were primarily affected by strong growth in non-maturity deposits coupled with a sharp decline in market discount rates resulting in higher valuations.

We do not typically utilize interest rate swaps, floors, collars or other derivative financial instruments to attempt to hedge our overall balance sheet rate sensitivity and interest rate risk.

58

Liquidity risk management

Liquidity risk is the risk that an institution will be unable to generate or obtain sufficient cash or its equivalents on a cost-effective basis to meet commitments as they fall due. The most common sources of liquidity risk arise from mismatches in the timing and value of on-balance sheet and off-balance sheet cash inflows and outflows. In general, on-balance sheet mismatches generate liquidity risk when the effective maturity of assets exceeds the effective maturity of liabilities. A commonly cited example of a balance sheet liquidity mismatch is when long-term loans (assets) are funded with short-term borrowings (liabilities). Other forms of liquidity risk include market constraints on the ability to convert assets into cash at expected levels, an inability to access funding sources at sufficient levels at a reasonable cost, and changes in economic conditions or exposure to credit, market, operational, legal and reputation risks that can affect an institution’s liquidity risk profile.

We utilize various limit-based measures to monitor, measure and control liquidity risk across three different types of liquidity:

• Tactical liquidity measures the risk of a negative cash flow position whereby cash outflows exceed cash inflows over a short-term horizon out to nine weeks;

• Structural liquidity measures the amount by which illiquid assets are supported by long-term funding; and

• Contingent liquidity utilizes cash flow stress testing across three crisis scenarios to determine the adequacy of our liquidity.

We aim to maintain a diverse mix of liquidity sources to support the liquidity management function, while aiming to avoid funding concentrations by diversifying our external funding with respect to maturities, counterparties and nature. Our primary source of liquidity is our retail deposit book due to the generally stable balances and low cost it offers. Additional sources include cash in excess of our reserve requirement at the Federal Reserve Bank, and various other corresponding bank accounts and unencumbered securities, which totaled $4.07 billion at June 30, 2019 compared to $3.11 billion at December 31, 2018. Another source of available funds was advances from the FHLB of Atlanta and Chicago. Outstanding FHLB advances were $197.2 million as of June 30, 2019, and we had sufficient collateral pledged to secure $6.26 billion of additional borrowings from the FHLB of Atlanta. Also, at June 30, 2019, $2.73 billion in non-PCI loans with a lendable collateral value of $2.09 billion were used to create additional borrowing capacity at the Federal Reserve Bank. We also maintain Federal Funds lines which had $732.7 million of available capacity at June 30, 2019.

CRITICAL ACCOUNTING ESTIMATES

There have been no significant changes in our Critical Accounting Estimates as described in our 2018 Annual Report on Form 10‑K.

FORWARD-LOOKING STATEMENTS

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Market risk is the potential economic loss resulting from changes in market prices and interest rates. This risk can either result in diminished current fair values of financial instruments or reduced net interest income in future periods. As of June 30, 2019, BancShares’ market risk profile has not changed significantly from December 31, 2018 as discussed in the Form 10-K. Changes in fair value that result from movement in market rates cannot be predicted with any degree of certainty. Therefore, the impact that future changes in market rates will have on the fair values of financial instruments is uncertain.

Item 4.    Controls and Procedures

BancShares' management, with the participation of its Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the design and operation of BancShares' disclosure controls and procedures as of the end of the period covered by this Quarterly Report, in accordance with Rule 13a-15 of the Securities Exchange Act of 1934 (Exchange Act). Based upon that evaluation, as of the end of the period covered by this report, the Chief Executive Officer and the Chief Financial Officer concluded that BancShares' disclosure controls and procedures were effective to provide reasonable assurance that it is able to record, process, summarize and report in a timely manner the information required to be disclosed in the reports it files under the Exchange Act.

No changes in BancShares' internal control over financial reporting occurred during the second quarter of 2019 that have materially affected, or are reasonably likely to materially affect, BancShares' internal control over financial reporting.

PART II

Item 1. Legal Proceedings

BancShares and various subsidiaries have been named as defendants in various legal actions arising from our normal business activities in which damages in various amounts were claimed. Although the amount of any ultimate liability with respect to those matters cannot be determined, in the opinion of management, no legal actions currently exist that are expected to have a material effect on BancShares’ consolidated financial statements. Additional information relating to legal proceedings is set forth in Note L of BancShares' Notes to Unaudited Consolidated Financial Statements.

Item 1A. Risk Factors

There have been no material changes from risk factors described in our annual Form 10-K for the year ended December 31, 2018. The risks described may not be the only risks facing us. Additional risks and uncertainties not currently known to us or that are currently considered to not be material also may materially adversely affect our business, financial condition and/or operating results.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Information concerning BancShares' repurchases of outstanding common stock during the three month period ended June 30, 2019, is included in the following table:

In October 2018, the Board authorized the purchase of up to 800,000 of BancShares' Class A common stock for the period November 1, 2018 through October 31, 2019. In April 2019, the Board authorized the repurchase of up to 800,000 of BancShares' Class A common stock for the period July 1, 2019 through June 30, 2020. This authorization was effective July 1, 2019 and supersedes the authorization approved in October 2018.

Accounting Policies [Abstract]

Accounting Policies and Basis of Presentation

ACCOUNTING POLICIES AND BASIS OF PRESENTATION

First Citizens BancShares, Inc. (BancShares) is a financial holding company organized under the laws of Delaware and conducts operations through its banking subsidiary, First-Citizens Bank & Trust Company (FCB), which is headquartered in Raleigh, North Carolina.

General

These consolidated financial statements and notes thereto are presented in accordance with instructions for Form 10-Q and Article 10 of Regulation S-X and, therefore, do not include all information and notes necessary for a complete presentation of financial position, results of operations and cash flow activity required in accordance with accounting principles generally accepted in the United States of America (GAAP). In the opinion of management, all normal recurring adjustments necessary for a fair presentation of the consolidated financial position and consolidated results of operations have been made. The unaudited interim consolidated financial statements included in this Form 10-Q should be read in conjunction with the consolidated financial statements and notes to consolidated financial statements included in BancShares' Annual Report on Form 10-K for the year ended December 31, 2018.

Reclassifications

In certain instances, amounts reported in prior years' consolidated financial statements have been reclassified to conform to the current financial statement presentation. Such reclassifications had no effect on previously reported cash flows, shareholders' equity or net income.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported. Actual results could differ from those estimates. The estimates that BancShares considers significant are the allowance for loan and lease losses, fair value measurements, Federal Deposit Insurance Corporation (FDIC) shared-loss payable, pension plan assumptions, goodwill and other intangible assets, and income taxes.

Share Repurchases

In October 2018, BancShares' Board of Directors (Board) authorized the repurchase of up to 800,000 of BancShares' Class A common stock for the period November 1, 2018 through October 31, 2019. The authorization does not obligate BancShares to repurchase any particular amount of shares, and repurchases may be suspended or discontinued at any time. During the second quarter of 2019, BancShares repurchased 205,500 shares of Class A common stock for $89.8 million at an average cost per share of $436.81. During the first six months of 2019, BancShares repurchased a total of 448,500 shares of Class A common stock for $190.5 million at an average cost per share of $424.77. As of June 30, 2019, a total of 630,500 shares have been repurchased under the current Board authority. There were no share repurchases made during the comparable periods in 2018.

In April 2019, the Board authorized the repurchase of up to 800,000 of BancShares' Class A common stock for the period July 1, 2019 through June 30, 2020. This authorization was effective July 1, 2019 and supersedes the authorization approved in October 2018. Under this authorization and subsequent to quarter-end through August 2, 2019, BancShares repurchased an additional 69,600 shares of Class A common stock for $31.7 million at an average cost per share of $455.94.

Recently Adopted Accounting Pronouncements

Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) 2016-02, Leases (Topic 842)

This ASU increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The key difference between prior standards and this ASU is the requirement for lessees to recognize all lease contracts on their balance sheet. This ASU requires lessees to classify leases as either operating or finance leases, which are substantially similar to the previous operating and capital leases classifications. The distinction between these two classifications under the new standard does not relate to balance sheet treatment, but relates to treatment in the statements of income and cash flows. Lessor guidance remains largely unchanged with the exception of how a lessor determines the appropriate lease classification for each lease to better align the lessor guidance with revised lessee classification guidance.

We adopted this standard, as of January 1, 2019, using the effective date method that allows for entities to initially apply the new leases standard at the adoption date. In addition, we made several policy elections permitted under the transition guidance, which among other things, allowed us to carry forward the historical lease classification. We determined that most renewal options would not be reasonably determinable in estimating the expected lease term.

We made the policy election available under Topic 842 to combine lease and non-lease components and applied this practical expedient to leases in effect prior to the date of adoption. We will continue to apply the practical expedient to all leases entered into going forward.

The adoption of the new standard had an impact on our Consolidated Balance Sheet as of January 1, 2019, with the recording of operating Right-of-Use (ROU) assets and operating lease liabilities of $70.7 million and $71.8 million, respectively. The operating lease liability includes a $1.1 million fair value adjustment for leases assumed in the acquisition of HomeBancorp, Inc. (HomeBancorp). In addition, at the adoption date we had finance lease ROU assets and finance lease liabilities, previously classified as capital leases, of $9.1 million and $8.3 million, respectively.  The Company did not have a cumulative-effect adjustment to the opening balance of retained earnings at commencement. The Company has no related party lease agreements.  This ASU did not have a material impact on our Consolidated Statements of Income. See Note N in the Consolidated Financial Statements for additional disclosures.

Recently Issued Accounting Pronouncements

FASB ASU 2018-15 - Intangibles - Goodwill and Other - Internal Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract

This ASU aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include internal-use software license). This ASU requires entities to use the guidance in FASB ASC 350-40, Intangibles - Goodwill and Other - Internal Use Software, to determine whether to capitalize or expense implementation costs related to the service contract. This ASU also requires entities to (1) expense capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement (2) present the expense related to the capitalized implementation costs in the same line item on the income statement as fees associated with the hosting element of the arrangement (3) classify payments for capitalized implementation costs in the statement of cash flows in the same manner as payments made for fees associated with the hosting element (4) present the capitalized implementation costs in the same balance sheet line item that a prepayment for the fees associated with the hosting arrangement would be presented.

The amendments in this ASU are effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted. BancShares adopted this standard effective July 1, 2019 on a prospective basis. BancShares is currently evaluating the impact of this ASU adoption, but does not anticipate a material impact on our Consolidated Financial Statements.

FASB ASU 2018-14 - Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans

This ASU modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans by eliminating the requirement to disclose the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year and adding a requirement to disclose an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period.

The amendments in this ASU are effective for public entities for fiscal years ending after December 15, 2020. Early adoption is permitted for all entities. BancShares will adopt all applicable amendments and update the disclosures as appropriate during the first quarter of 2021.

FASB ASU 2018-13 - Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement

This ASU modifies the disclosure requirements on fair value measurements by eliminating the requirements to disclose (1) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy (2) the policy for timing of transfers between levels and (3) the valuation processes for Level 3 fair value measurements. This ASU also added specific disclosure requirements for fair value measurements for public business entities including the requirement to disclose the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements.

The amendments in this ASU are effective for all entities for fiscal years beginning after December 15, 2019, and all interim periods within those fiscal years. Early adoption is permitted upon issuance of the ASU. Entities are permitted to early adopt amendments that remove or modify disclosures and delay the adoption of the additional disclosures until their effective date. BancShares will adopt all applicable amendments and update the disclosures as appropriate during the first quarter of 2020.

FASB ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment

This ASU eliminates Step 2 from the goodwill impairment test. Under Step 2, an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities) following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, under the amendments in this ASU, 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. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. This ASU eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative test.

This ASU will be effective for BancShares' annual or interim goodwill impairment tests for fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We expect to adopt the guidance for our annual impairment test in fiscal year 2020. BancShares does not anticipate any impact to our consolidated financial position or consolidated results of operations as a result of the adoption.

FASB ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments

This ASU introduces a new credit loss methodology which requires earlier recognition of credit losses, replacing multiple existing impairment methods in current GAAP, which generally require that a loss be incurred before it is recognized. The amendments in this ASU require loss estimates be determined over the lifetime of the asset and broaden the information that an entity must consider in developing its expected credit losses. The ASU does not specify a method for measuring expected credit losses and allows an entity to apply methods that reasonably reflect its expectations of the credit loss estimate based on the entity's size, complexity and risk profile. In addition, the disclosures of credit quality indicators in relation to the amortized cost of financing receivables, a current disclosure requirement, are further disaggregated by year of origination.

For BancShares, the standard will apply to loans, unfunded loan commitments and debt securities. A cross-functional team co-led by Corporate Finance and Risk Management is in place to implement the new standard. We have completed preliminary current expected credit losses (CECL) accounting interpretations, and continue to refine and test our models, estimation techniques, data, operational processes and controls to be used in preparing CECL loss estimates. During the remainder of 2019, we expect to address any gaps in our interpretations, including review of subsequent ASUs announced by the FASB regarding Topic 326, methodology, data and operational processes based upon our reviews and tests. BancShares continues to evaluate the impact of this standard on its consolidated financial statements but the magnitude of this impact has not been determined. The final impact will be dependent on, among other items, loan portfolio composition and credit quality at the adoption date, as well as economic conditions, financial models used and forecasts in place at that time.

The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018. BancShares will adopt the guidance in the first quarter of 2020 with a cumulative-effect adjustment to retained earnings as of the beginning of the year of adoption.

Entegra Financial Corp.

On April 23, 2019, FCB and Entegra Financial Corp. (Entegra) entered into a definitive merger agreement for the acquisition by FCB of Franklin, North Carolina-based Entegra and its bank subsidiary, Entegra Bank. Under the terms of the agreement, cash consideration of $30.18 per share will be paid to the shareholders of Entegra for each share of common stock and for each restricted stock unit after conversion to common stock, and each option to purchase Entegra common stock will be canceled and each option holder will receive a cash payment.The total transaction value is estimated to be approximately $219.8 million. The transaction is anticipated to close during the fourth quarter of 2019, subject to the receipt of regulatory approvals and the satisfaction of other customary closing conditions. As of June 30, 2019, Entegra reported $1.66 billion in consolidated assets, $1.25 billion in deposits and $1.09 billion in loans.

First South Bancorp, Inc.

On May 1, 2019, FCB completed the merger of Spartanburg, South Carolina-based First South Bancorp, Inc. (First South Bancorp) and its bank subsidiary, First South Bank. Under the terms of the agreement, cash consideration of $1.15 per share was paid to the shareholders of First South Bancorp for each share of common stock, totaling approximately $37.5 million. The merger allows FCB to expand its presence in South Carolina.

The First South Bancorp transaction was accounted for under the acquisition method of accounting and, accordingly, assets acquired and liabilities assumed were recorded at their estimated fair values on the acquisition date. Fair values are preliminary and subject to refinement for up to one year after the closing date of the acquisition as additional information regarding closing date fair values becomes available.

The fair value of the assets acquired was $239.2 million, including $162.8 million in non-purchased credit impaired (non-PCI) loans, $16.4 million in purchased credit impaired (PCI) loans and $2.3 million in a core deposit intangible. Liabilities assumed were $215.6 million, of which $207.6 million were deposits. As a result of the transaction, FCB recorded $13.9 million of goodwill. The amount of goodwill represents the excess purchase price over the estimated fair value of the net assets acquired. The premium paid reflects the increased market share and related synergies that are expected to result from the acquisition. None of the goodwill was deductible for income tax purposes as the merger was accounted for as a qualified stock purchase.

Based on such credit factors as past due status, nonaccrual status, loan-to-value, credit scores, and other quantitative and qualitative considerations, the acquired loans were separated into loans with evidence of credit deterioration, which are accounted for under ASC 310-30 (PCI loans), and loans that do not meet this criteria, which are accounted for under ASC 310-20 (non-PCI loans).

The following table provides the purchase price as of the acquisition date and the identifiable assets acquired and liabilities assumed at their estimated fair values:

(Dollars in thousands)	As recorded by FCB
Purchase price			$	37,486

Merger-related expenses of $1.2 million and $1.4 million were recorded in the Consolidated Statements of Income for the three and six months ended June 30, 2019, respectively. Loan-related interest income generated from First South Bancorp was approximately $1.7 million since the acquisition date. The ongoing contributions of this transaction to BancShares' financial statements is not considered material, and therefore pro forma financial data is not included.

Biscayne Bancshares, Inc.

On April 2, 2019, FCB completed the merger of Coconut Grove, Florida-based Biscayne Bancshares, Inc. (Biscayne Bancshares) and its bank subsidiary, Biscayne Bank. Under the terms of the agreement, cash consideration of $25.05 per share was paid to the shareholders of Biscayne Bancshares for each share of common stock, totaling approximately $118.9 million. The merger will allow FCB to expand its presence in Florida and enhance banking efforts in South Florida.

The Biscayne Bancshares transaction was accounted for under the acquisition method of accounting and, accordingly, assets acquired and liabilities assumed were recorded at their estimated fair values on the acquisition date. Fair values are preliminary and subject to refinement for up to one year after the closing date of the acquisition as additional information regarding closing date fair values becomes available.

The fair value of the assets acquired was $1.03 billion, including $850.4 million in non-purchased credit impaired (non-PCI) loans, $13.0 million in purchased credit impaired (PCI) loans and $4.7 million in a core deposit intangible. Liabilities assumed were $956.8 million, of which $786.5 million were deposits. As a result of the transaction, FCB recorded $46.5 million of goodwill. The amount of goodwill represents the excess purchase price over the estimated fair value of the net assets acquired. The premium paid reflects the increased market share and related synergies that are expected to result from the acquisition. None of the goodwill was deductible for income tax purposes as the merger was accounted for as a qualified stock purchase.

Based on such credit factors as past due status, nonaccrual status, loan-to-value, credit scores, and other quantitative and qualitative considerations, the acquired loans were separated into loans with evidence of credit deterioration, which are accounted for under ASC 310-30 (PCI loans), and loans that do not meet this criteria, which are accounted for under ASC 310-20 (non-PCI loans).

Loans and Leases

LOANS AND LEASES

BancShares' accounting methods for loans and leases differ depending on whether they are non-purchased credit impaired (Non-PCI) or purchased credit impaired (PCI). Loans that were originated by FCB, as well as loans that are performing under their contractual obligations at acquisition, are classified as Non-PCI. Loans that reflect credit deterioration since origination, such that it is probable at acquisition that FCB will be unable to collect all contractually required payments, are classified as PCI. Additionally, at the date of acquisition, all acquired loans are recorded at fair value with no corresponding allowance for loan and lease losses.

Loans and leases outstanding included the following at June 30, 2019 and December 31, 2018:

(Dollars in thousands)	June 30, 2019		December 31, 2018

At June 30, 2019, $9.16 billion in non-PCI loans with a lendable collateral value of $6.45 billion were used to secure $183.7 million in Federal Home Loan Bank (FHLB) of Atlanta advances and $13.5 million in FHLB of Chicago advances, resulting in additional borrowing capacity of $6.26 billion. At December 31, 2018, $9.12 billion in non-PCI loans with a lendable collateral value of $6.36 billion were used to secure $175.2 million in FHLB of Atlanta advances, resulting in additional borrowing capacity of $6.18 billion.

At June 30, 2019, $2.73 billion in non-PCI loans with a lendable collateral value of $2.09 billion were used to secure additional borrowing capacity at the Federal Reserve Bank (FRB). At December 31, 2018, $2.94 billion in non-PCI loans with a lendable collateral value of $2.19 billion were used to secure additional borrowing capacity at the FRB.

Certain residential real estate loans are originated to be sold to investors and are recorded in loans held for sale at fair value. In addition, we may change our strategy for certain portfolio loans and decide to sell them in the secondary market. At that time, portfolio loans are transferred to loans held for sale at fair value. Since December 31, 2018, $23.9 million in portfolio loans were transfered to held for sale and subsequently sold. Loans held for sale totaled $52.8 million and $45.5 million at June 30, 2019 and December 31, 2018, respectively.

Net deferred fees on non-PCI loans and leases, including unearned income as well as unamortized costs and fees, were $0.5 million and $0.1 million at June 30, 2019 and December 31, 2018, respectively. The net unamortized discount related to purchased non-PCI loans and leases was $35.7 million at June 30, 2019 and $33.3 million at December 31, 2018. During the three months ended June 30, 2019 and June 30, 2018, accretion income on purchased non-PCI loans and leases was $3.3 million and $4.1 million, respectively. During the six months ended June 30, 2019 and June 30, 2018, accretion income on purchased non-PCI loans and leases was $6.5 million and $7.0 million, respectively.

Credit quality indicators

Loans and leases are monitored for credit quality on a recurring basis. Commercial and noncommercial loans and leases have different credit quality indicators as a result of the unique characteristics of the loan segments being evaluated. The credit quality indicators for non-PCI and PCI commercial loans and leases are developed through a review of individual borrowers on an ongoing basis. Commercial loans are evaluated periodically with more frequent evaluations done on criticized loans. Commercial credit cards are included in the Commercial and industrial and leases segment, but are not specifically graded as with other commercial loans. The indicators as of the date presented are based on the most recent assessment performed and are defined below:

Pass – A pass rated asset is not adversely classified because it does not display any of the characteristics for adverse classification.

Special mention – A special mention asset has potential weaknesses that deserve management’s close attention. If left uncorrected, such potential weaknesses may result in deterioration of the repayment prospects or collateral position at some future date. Special mention assets are not adversely classified and do not warrant adverse classification.

Substandard – A substandard asset is inadequately protected by the current net worth and paying capacity of the borrower or of the collateral pledged, if any. Assets classified as substandard generally have a well-defined weakness, or weaknesses, that jeopardize the liquidation of the debt. These assets are characterized by the distinct possibility of loss if the deficiencies are not corrected.

Doubtful – An asset classified as doubtful has all the weaknesses inherent in an asset classified substandard with the added characteristic that the weaknesses make collection or liquidation in full highly questionable and improbable on the basis of currently existing facts, conditions and values.

Loss – Assets classified as loss are considered uncollectible and of such little value that it is inappropriate to be carried as an asset. This classification is not necessarily equivalent to any potential for recovery or salvage value, but rather that it is not appropriate to defer a full charge-off even though partial recovery may be affected in the future.

Ungraded – Ungraded loans represent loans that are not included in the individual credit grading process due to their relatively small balances or borrower type. The majority of ungraded loans at June 30, 2019 and December 31, 2018 relate to business credit cards. Business credit card loans are subject to automatic charge-off when they become 120 days past due in the same manner as unsecured consumer lines of credit. The remaining balance is comprised of a small amount of commercial mortgage, lease financing and other commercial real estate loans.

The credit quality indicators for non-PCI and PCI noncommercial loans are based on delinquency status of the borrower as of the date presented. As the borrower becomes more delinquent, the likelihood of loss increases.

Balance at June 30	$	551,447		$	674,269
Unpaid principal balance at June 30	$	805,754		$	1,044,148

The carrying value of PCI loans on the cost recovery method was $3.3 million at both June 30, 2019 and December 31, 2018. The cost recovery method is applied to loans when the timing of future cash flows cannot be reasonably estimated due to borrower nonperformance or uncertainty in the ultimate disposition of the asset. The recorded investment of PCI loans on nonaccrual status was $4.3 million and $1.3 million at June 30, 2019 and December 31, 2018, respectively. The remaining discount on PCI loans was $93.0 million and $95.5 million at June 30, 2019 and December 31, 2018, respectively.

During the three months ended June 30, 2019 and June 30, 2018, accretion income on PCI loans was $11.9 million and $14.2 million, respectively. During the six months ended June 30, 2019 and June 30, 2018, accretion income on PCI loans was $29.6 million and $32.2 million, respectively.

For PCI loans, improved credit loss expectations generally result in the reclassification of nonaccretable difference to accretable yield. Changes in expected cash flow not related to credit improvements or deterioration do not affect the nonaccretable difference.

The following table documents changes to the amount of accretable yield for the first six months of 2019 and 2018:

Troubled Debt Restructurings

BancShares accounts for certain loan modifications or restructurings as troubled debt restructurings (TDRs). In general, the modification or restructuring of a loan is considered a TDR if, for economic reasons or legal reasons related to a borrower's financial difficulties, a concession is granted to the borrower that creditors would not otherwise consider. Concessions may relate to the contractual interest rate, maturity date, payment structure or other actions. The majority of TDRs are included in the special mention, substandard or doubtful credit quality indicators, which results in more elevated loss expectations when projecting the expected cash flows that are used to determine the allowance for loan losses associated with these loans. The lower the credit quality indicator, the lower the estimated expected cash flows and the greater the allowance recorded. All TDRs are individually evaluated for impairment through review of collateral values or analysis of cash flows at least annually.

The following table provides a summary of total TDRs by accrual status. Total TDRs included $18.0 million and $18.2 million of PCI TDRs at June 30, 2019 and December 31, 2018, respectively:

As of June 30, 2019, shared-loss protection remains for single family residential loans acquired in the amount of $50.2 million. The shared-loss agreements for two FDIC-assisted transactions include provisions related to payments that may be owed to the FDIC at the termination of the agreements (clawback liability). The clawback liability represents a payment by BancShares to the FDIC if actual cumulative losses on acquired covered assets are lower than the cumulative losses originally estimated by the FDIC at the time of acquisition and is recorded in the Consolidated Balance Sheets as a payable to the FDIC under the relevant shared-loss agreements. The clawback liability payment dates are March 2020 and March 2021.

Mortgage Servicing Rights [Abstract]

Transfers and Servicing of Financial Assets [Text Block]

Our portfolio of residential mortgage loans serviced for third parties was $3.01 billion and $2.95 billion as of June 30, 2019 and December 31, 2018, respectively. These loans are originated by BancShares and sold to third parties on a non-recourse basis with servicing rights retained. The retained servicing rights were recorded as a servicing asset and reported in other intangible assets on the Consolidated Balance Sheets, and the associated amortization expense and any valuation allowance recognized was included as a reduction of mortgage income in the Consolidated Statements of Income. The mortgage servicing rights were initially recorded at fair value and then carried at the lower of amortized cost or fair value.

Contractually specified mortgage servicing fees, late fees, and ancillary fees earned for the three months ended June 30, 2019 and 2018 were $2.0 million and $1.9 million, respectively, and reported in mortgage income in the Consolidated Statements of Income. For the six months ended June 30, 2019 and 2018, contractually specified mortgage servicing fees, late fees, and ancillary fees earned were $3.9 million and $3.8 million, respectively.

The following table explains changes in the servicing asset during the three and six months ended June 30, 2019 and 2018:

	Three months ended June 30						Six months ended June 30
(Dollars in thousands)	2019			2018			2019			2018
Beginning balance	$	20,647		$	21,659		$	21,396		$	21,945

Valuation allowance credit (provision)	33			—			(128		)	—
Ending balance	$	20,665		$	21,657		$	20,665		$	21,657

BancShares released $33.0 thousand of the valuation allowance for the three months ended June 30, 2019 and recorded provision expense of $128.0 thousand for the six months ended June 30, 2019. There was no valuation allowance provision expense or release recorded for the the three and six months ended June 30, 2018. Mortgage servicing rights valuations are performed using a pooling methodology where similar loans are grouped together and evaluated using discounted cash flows to estimate the present value of future earnings. Key economic assumptions used to value mortgage servicing rights were as follows:

	June 30, 2019			December 31, 2018
Discount rate - conventional fixed loans	9.01		%	9.69		%
Discount rate - all loans excluding conventional fixed loans	10.01		%	10.69		%
Weighted average constant prepayment rate	13.39		%	9.26		%
Weighted average cost to service a loan	$	88.03		$	87.52

The fair value of mortgage servicing rights is sensitive to changes in assumptions and is determined by estimating the present value of the asset's future cash flows by utilizing discount rates, prepayment rates, and other inputs. The discount rate is based on the 10-year U.S. Treasury rate plus 700 basis points for conventional fixed loans and 800 basis points for all other loans. The 700 and 800 basis points were used as a risk premium when calculating the discount rate. The prepayment rate is derived from the Public Securities Association Standard Prepayment model. Generally, as interest rates decline, mortgage loan prepayments accelerate due to increased refinance activity. This results in a decrease in fair value. The average cost to service a loan is based on the number of loans serviced and the total costs to service the loans.

Other Servicing Rights

Other servicing rights were acquired as part of a business combination and relate to the sale of the guaranteed portion of government guaranteed loans with servicing retained. The amount of the other servicing rights were $2.1 million and $2.7 million at June 30, 2019 and December 31, 2018, respectively.

Repurchase Agreements, Resale Agreements, Securities Borrowed, and Securities Loaned Disclosure [Text Block]

REPURCHASE AGREEMENTS

BancShares, through FCB, utilizes securities sold under customer repurchase agreements to facilitate the needs of customers and secure wholesale funding needs. Repurchase agreements are transactions whereby FCB offers to sell to a counterparty an undivided interest in an eligible security, and which obligates FCB to repurchase the security, with interest, at an agreed upon date, repurchase price, and interest rate. These agreements are recorded at the amount of cash received in connection with the transaction and are reflected as securities sold under customer repurchase agreements on the Consolidated Balance Sheets.

Repurchase agreements require FCB to maintain collateral to support the outstanding obligations. BancShares monitors collateral levels on a continuous basis and maintains records of each transaction specifically describing the applicable security and the counterparty’s fractional interest in that security, and segregates the security from general assets in accordance with regulations governing custodial holdings of securities. The primary risk with repurchase agreements is market risk associated with the investments securing the transactions, as additional collateral may be required based on fair value changes of the underlying investments. Securities pledged as collateral under repurchase agreements are maintained with safekeeping agents and consist of U.S. Treasury securities. The carrying value of investment securities pledged as collateral under repurchase agreements was $612.5 million and $598.6 million at June 30, 2019 and December 31, 2018, respectively.

The remaining contractual maturity of the $544.5 million and $543.9 million securities sold under repurchase agreements at June 30, 2019 and December 31, 2018, respectively, was overnight and continuous.

Fair Value Disclosures [Abstract]

Estimated Fair Values

ESTIMATED FAIR VALUES

Fair value estimates are intended to represent the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. Where there is no active market for a financial instrument, BancShares has made estimates using discounted cash flows or other valuation techniques. Inputs used in these valuation techniques are subjective in nature, involve uncertainties and require significant judgment and therefore can only be derived within a range of precision. Accordingly, the derived fair value estimates presented below are not necessarily indicative of the amounts BancShares would realize in a current market exchange.

ASC 820, Fair Value Measurements and Disclosures, indicates that assets and liabilities are recorded at fair value according to a fair value hierarchy comprised of three levels. The levels are based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. The level within the fair value hierarchy for an asset or liability is based on the highest level of input that is significant to the fair value measurement (with Level 1 considered highest and Level 3 considered lowest). A brief description of each level follows:

• Level 1 values are based on quoted prices for identical instruments in active markets.

• Level 2 values are based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market.

• Level 3 values are derived from valuation techniques in which one or more significant inputs or assumptions are not observable in the market. These unobservable inputs and assumptions reflect estimates that market participants would use in pricing the asset or liability. Valuation techniques include the use of discounted cash flow models and similar techniques.

BancShares' management reviews any changes to its valuation methodologies to ensure they are appropriate and supportable, and refines valuation methodologies as more market-based data becomes available. Transfers between levels of the fair value hierarchy are recognized at the end of the reporting period.

The methodologies used to estimate the fair value of financial assets and financial liabilities are discussed below:

Investment securities available for sale. Investment securities available for sale are carried at fair value. U.S. Treasury, government agency and mortgage-backed securities are generally measured at fair value using a third party pricing service. The third party provider evaluates securities based on comparable investments with trades and market data and will utilize pricing models that use a variety of inputs, such as benchmark yields, reported trades, broker-dealer quotes, issuer spreads, benchmark securities, bids and offers as needed. These securities are generally classified as Level 2. Corporate bonds and trust preferred securities are generally measured at fair value based on indicative bids from broker-dealers and are not directly observable. These securities are considered Level 3.

Investment in marketable equity securities. Equity securities are measured at fair value using observable closing prices and the valuation also considers the amount of market activity by examining the trade volume of each security. Equity securities are classified as Level 1 if they are traded in an active market and as Level 2 if the observable closing price is from a less than active market.

Loans held for sale. Certain residential real estate loans that are originated to be sold to investors are carried at fair value based on quoted market prices for similar types of loans. Accordingly, the inputs used to calculate fair value of originated residential real estate loans held for sale are classified as Level 2 inputs. Portfolio loans that are subsequently transferred to held for sale to be sold in the secondary market are carried at fair value when a firm commitment from a counterparty exists. The fair value of the transferred portfolio loans is based on the quoted prices and is considered a Level 1 input.

Net loans and leases (PCI and Non-PCI). Fair value is estimated based on discounted future cash flows using the current interest rates at which loans with similar terms would be made to borrowers of similar credit quality. The inputs used in the fair value measurements for loans and leases are considered Level 3 inputs.

FHLB stock. The carrying amount of FHLB stock is a reasonable estimate of fair value as these securities are not readily marketable and are evaluated for impairment based on the ultimate recoverability of the par value. BancShares considers positive and negative evidence, including the profitability and asset quality of the issuer, dividend payment history and recent redemption experience, when determining the ultimate recoverability of the par value. BancShares believes its investment in FHLB stock is ultimately recoverable at par. The inputs used in the fair value measurement for the FHLB stock are considered Level 2 inputs.

Mortgage and other servicing rights. Mortgage and other servicing rights are carried at the lower of amortized cost or market and are, therefore, carried at fair value only when fair value is less than the amortized cost. The fair value of mortgage and other servicing rights is performed using a pooling methodology. Similar loans are pooled together and a model that relies on discount rates, estimates of prepayment rates and the weighted average cost to service the loans is used to determine the fair value. The inputs used in the fair value measurement for mortgage and other servicing rights are considered Level 3 inputs.

Deposits. For non-time deposits, carrying value is a reasonable estimate of fair value. The fair value of time deposits is estimated by discounting future cash flows using the interest rates currently offered for deposits of similar remaining maturities. The inputs used in the fair value measurement for deposits are considered Level 2 inputs.    

Borrowings. For borrowings, the fair values are determined based on recent trades or sales of the actual security if available, otherwise, fair values are estimated by discounting future cash flows using current interest rates for similar financial instruments. The inputs used in the fair value measurement for long-term borrowings are considered Level 2 inputs.

Payable to the FDIC for shared-loss agreements. The fair value of the payable to the FDIC for shared-loss agreements is determined by the projected cash flows based on expected payments to the FDIC in accordance with the shared-loss agreements. Cash flows are discounted using current discount rates to reflect the timing of the estimated amounts due to the FDIC. The inputs used in the fair value measurement for the payable to the FDIC are considered Level 3 inputs.

Off-balance-sheet commitments and contingencies. Carrying amounts are reasonable estimates of the fair values for such financial instruments. Carrying amounts include unamortized fee income and, in some cases, reserves for any credit losses from those financial instruments. These amounts are not material to BancShares' financial position.

 For all other financial assets and financial liabilities, the carrying value is a reasonable estimate of the fair value as of June 30, 2019 and December 31, 2018. The carrying value and fair value for these assets and liabilities are equivalent because they are relatively short term in nature and there is no interest rate or credit risk that would cause the fair value to differ from the carrying value. Cash and due from banks is classified on the fair value hierarchy as Level 1. Overnight investments, income earned not collected, securities sold under customer repurchase agreements, and accrued interest payable are considered Level 2.

The table presents the carrying values and estimated fair values for financial instruments as of June 30, 2019 and December 31, 2018:

Fair Value Option

BancShares has elected the fair value option for residential real estate loans originated to be sold. This election reduces certain timing differences in the Consolidated Statement of Income and better aligns with the management of the portfolio from a business perspective. The changes in fair value were recorded as a component of mortgage income and included a loss of $82 thousand and a gain of $700 thousand for the three months ended June 30, 2019 and June 30, 2018, respectively. The changes in fair value included a gain of $167 thousand and $245 thousand for six months ended June 30, 2019 and June 30, 2018, respectively.

The following table summarizes the difference between the aggregate fair value and the aggregate unpaid principal balance for residential real estate originated for sale measured at fair value as of June 30, 2019 and December 31, 2018:

	December 31, 2018
	Fair Value		Aggregate Unpaid Principal Balance		Difference
Originated loans held for sale	$	45,505	$	44,073	$	1,432

No originated loans held for sale were 90 or more days past due or on nonaccrual status as of June 30, 2019 or December 31, 2018.

We may be required to measure certain financial assets at fair value on a nonrecurring basis. These adjustments to fair value usually result from the application of lower of amortized cost or fair value accounting or write-downs of individual assets due to impairment.

Impaired loans are deemed to be at fair value if an associated allowance or current period charge-off has been recorded. The value of impaired loans is determined by either collateral valuations or discounted present value of the expected cash flow calculations. Collateral values are determined using appraisals or other third-party value estimates of the subject property with discounts generally between 6% and 11% applied for estimated selling costs and other external factors that may impact the marketability of the property. Expected cash flows are determined using expected payment information at the individual loan level, discounted using the effective interest rate. The effective interest rate generally ranges between 2% and 18%.

OREO acquired or written down within the previous 12 months is deemed to be at fair value. Asset valuations are determined by using appraisals or other third-party value estimates of the subject property with discounts generally between 6% and 11% applied for estimated selling costs and other external factors that may impact the marketability of the property. Changes to the value of the assets between scheduled valuation dates are monitored through continued communication with brokers and monthly reviews by the asset manager assigned to each asset. If there are any significant changes in the market or the subject property, valuations are adjusted or new appraisals ordered to ensure the reported values reflect the most current information.

For financial assets and liabilities carried at fair value on a nonrecurring basis, the following table provides fair value information as of June 30, 2019 and December 31, 2018:

	Three months ended June 30						Six months ended June 30
(Dollars in thousands)	2019			2018			2019			2018
Service cost	$	581		$	624		$	1,126		$	1,286
Interest cost	1,757			1,592			3,517			3,179
Expected return on assets	(2,775		)	(3,110		)	(5,543		)	(6,216		)

No discretionary contributions were made during the six months ended June 30, 2019 to the BancShares or Bancorporation pension plans. Management evaluates the need for its pension plan contributions on a periodic basis based upon numerous factors including, but not limited to, the funded status of the plans, returns on plan assets, discount rates and the current economic environment. BancShares made a contribution of $3.5 million to the Bancorporation plan in July 2019.

Commitments and Contingencies

COMMITMENTS AND CONTINGENCIES

To meet the financing needs of its customers, BancShares and its subsidiaries have financial instruments with off-balance sheet risk. These financial instruments include commitments to extend credit and standby letters of credit. These instruments involve elements of credit, interest rate or liquidity risk.

Commitments to extend credit are legally binding agreements to lend to customers. Commitments generally have fixed expiration dates or other termination clauses and may require payment of fees. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future liquidity requirements. Established credit standards control the credit risk exposure associated with these commitments. In some cases, BancShares requires that collateral be pledged to secure the commitment, including cash deposits, securities and other assets.

Standby letters of credit are commitments guaranteeing performance of a customer to a third party. Those commitments are primarily issued to support public and private borrowing arrangements, and the fair value of those commitments was not material. To mitigate its risk, BancShares’ credit policies govern the issuance of standby letters of credit. The credit risk related to the issuance of these letters of credit is essentially the same as that involved in extending loans to clients and, therefore, these letters of credit are collateralized when necessary.

The following table presents the commitments to extend credit and unfunded commitments as of June 30, 2019 and December 31, 2018:

(Dollars in thousands)	June 30, 2019		December 31, 2018
Unused commitments to extend credit	$	10,348,284	$	10,054,712
Standby letters of credit	94,307		96,467
Unfunded commitments for investments in affordable housing projects	80,383		67,952

Affordable housing project investments were $170.3 million and $147.3 million as of June 30, 2019 and December 31, 2018, respectively, and were included in other assets on the Consolidated Balance Sheets.

BancShares and various subsidiaries have been named as defendants in legal actions arising from their normal business activities in which damages in various amounts were claimed. BancShares has also been exposed to litigation risk relating to the prior business activities of banks from which assets were acquired and liabilities assumed in the various merger transactions. Although the amount of any ultimate liability with respect to such matters cannot be determined, in the opinion of management, any such liability will not have a material effect on BancShares’ consolidated financial statements.

Leases [Abstract]

Leases

LEASES

BancShares leases certain branch locations, administrative offices and equipment. Operating lease ROU assets are included in other assets and the associated lease obligations are included in other liabilities on the Consolidated Balance Sheets. Finance leases are included in premises and equipment and other borrowings on the Consolidated Balance Sheets. Leases with an initial term of 12 months or less are not recorded on the Consolidated Balance Sheets; we instead recognize lease expense for these leases on a straight-line basis over the lease term.

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our corresponding obligation to make lease payments arising from the lease. Operating and finance lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. The operating and finance lease ROU asset also includes initial direct costs and pre-paid lease payments made, excluding lease incentives. As most of our leases do not provide an implicit rate, BancShares uses its incremental borrowing rate, based on the information available at commencement date in determining the present value of lease payments. The incremental borrowing rate is determined using secured rates for new FHLB advances under similar terms as the lease at inception. BancShares used the incremental borrowing rate on January 1, 2019, for operating leases that commenced prior to that date.

Most leases include one or more options to renew, with renewal terms that can extend the lease term from 1 to 25 years. The exercise of lease renewal options is at our sole discretion. When it is reasonably certain that we will exercise our option to renew or extend the lease term, that option is included in calculating the value of the ROU and lease liability. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise.

We determine if an arrangement is a lease at inception and our lease agreements do not contain any material residual value guarantees or material restrictive covenants. We have no related party lease agreements. As of June 30, 2019, there were no leases that have not yet commenced that would have a material impact on our Consolidated Financial Statements.

We rent or sublease certain real estate to third parties to manage occupancy costs and provide flexibility to expand and contract occupancy space to meet our business needs.

The following table presents lease costs for the three and six months ended June 30, 2019. Variable lease cost primarily represents variable payments such as common area maintenance and utilities that are recognized in the period in which the expense was incurred. Certain of our lease agreements also include rental payments that are adjusted periodically for inflation. While lease liabilities are not remeasured as a result of these changes, these adjustments are treated as a variable lease costs and recognized in the period in which the expense is incurred.

Accounting Policies [Abstract]

Reclassifications

Reclassifications

In certain instances, amounts reported in prior years' consolidated financial statements have been reclassified to conform to the current financial statement presentation. Such reclassifications had no effect on previously reported cash flows, shareholders' equity or net income.

Use of Estimates

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported. Actual results could differ from those estimates. The estimates that BancShares considers significant are the allowance for loan and lease losses, fair value measurements, Federal Deposit Insurance Corporation (FDIC) shared-loss payable, pension plan assumptions, goodwill and other intangible assets, and income taxes.

New Accounting Pronouncements

Recently Adopted Accounting Pronouncements

Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) 2016-02, Leases (Topic 842)

This ASU increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The key difference between prior standards and this ASU is the requirement for lessees to recognize all lease contracts on their balance sheet. This ASU requires lessees to classify leases as either operating or finance leases, which are substantially similar to the previous operating and capital leases classifications. The distinction between these two classifications under the new standard does not relate to balance sheet treatment, but relates to treatment in the statements of income and cash flows. Lessor guidance remains largely unchanged with the exception of how a lessor determines the appropriate lease classification for each lease to better align the lessor guidance with revised lessee classification guidance.

We adopted this standard, as of January 1, 2019, using the effective date method that allows for entities to initially apply the new leases standard at the adoption date. In addition, we made several policy elections permitted under the transition guidance, which among other things, allowed us to carry forward the historical lease classification. We determined that most renewal options would not be reasonably determinable in estimating the expected lease term.

We made the policy election available under Topic 842 to combine lease and non-lease components and applied this practical expedient to leases in effect prior to the date of adoption. We will continue to apply the practical expedient to all leases entered into going forward.

The adoption of the new standard had an impact on our Consolidated Balance Sheet as of January 1, 2019, with the recording of operating Right-of-Use (ROU) assets and operating lease liabilities of $70.7 million and $71.8 million, respectively. The operating lease liability includes a $1.1 million fair value adjustment for leases assumed in the acquisition of HomeBancorp, Inc. (HomeBancorp). In addition, at the adoption date we had finance lease ROU assets and finance lease liabilities, previously classified as capital leases, of $9.1 million and $8.3 million, respectively.  The Company did not have a cumulative-effect adjustment to the opening balance of retained earnings at commencement. The Company has no related party lease agreements.  This ASU did not have a material impact on our Consolidated Statements of Income. See Note N in the Consolidated Financial Statements for additional disclosures.

Recently Issued Accounting Pronouncements

FASB ASU 2018-15 - Intangibles - Goodwill and Other - Internal Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract

This ASU aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include internal-use software license). This ASU requires entities to use the guidance in FASB ASC 350-40, Intangibles - Goodwill and Other - Internal Use Software, to determine whether to capitalize or expense implementation costs related to the service contract. This ASU also requires entities to (1) expense capitalized implementation costs of a hosting arrangement that is a service contract over the term of the hosting arrangement (2) present the expense related to the capitalized implementation costs in the same line item on the income statement as fees associated with the hosting element of the arrangement (3) classify payments for capitalized implementation costs in the statement of cash flows in the same manner as payments made for fees associated with the hosting element (4) present the capitalized implementation costs in the same balance sheet line item that a prepayment for the fees associated with the hosting arrangement would be presented.

The amendments in this ASU are effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted. BancShares adopted this standard effective July 1, 2019 on a prospective basis. BancShares is currently evaluating the impact of this ASU adoption, but does not anticipate a material impact on our Consolidated Financial Statements.

This ASU modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans by eliminating the requirement to disclose the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year and adding a requirement to disclose an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period.

The amendments in this ASU are effective for public entities for fiscal years ending after December 15, 2020. Early adoption is permitted for all entities. BancShares will adopt all applicable amendments and update the disclosures as appropriate during the first quarter of 2021.

FASB ASU 2018-13 - Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement

This ASU modifies the disclosure requirements on fair value measurements by eliminating the requirements to disclose (1) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy (2) the policy for timing of transfers between levels and (3) the valuation processes for Level 3 fair value measurements. This ASU also added specific disclosure requirements for fair value measurements for public business entities including the requirement to disclose the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements.

The amendments in this ASU are effective for all entities for fiscal years beginning after December 15, 2019, and all interim periods within those fiscal years. Early adoption is permitted upon issuance of the ASU. Entities are permitted to early adopt amendments that remove or modify disclosures and delay the adoption of the additional disclosures until their effective date. BancShares will adopt all applicable amendments and update the disclosures as appropriate during the first quarter of 2020.

FASB ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment

This ASU eliminates Step 2 from the goodwill impairment test. Under Step 2, an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities) following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, under the amendments in this ASU, 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. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. This ASU eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative test.

This ASU will be effective for BancShares' annual or interim goodwill impairment tests for fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We expect to adopt the guidance for our annual impairment test in fiscal year 2020. BancShares does not anticipate any impact to our consolidated financial position or consolidated results of operations as a result of the adoption.

FASB ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments

This ASU introduces a new credit loss methodology which requires earlier recognition of credit losses, replacing multiple existing impairment methods in current GAAP, which generally require that a loss be incurred before it is recognized. The amendments in this ASU require loss estimates be determined over the lifetime of the asset and broaden the information that an entity must consider in developing its expected credit losses. The ASU does not specify a method for measuring expected credit losses and allows an entity to apply methods that reasonably reflect its expectations of the credit loss estimate based on the entity's size, complexity and risk profile. In addition, the disclosures of credit quality indicators in relation to the amortized cost of financing receivables, a current disclosure requirement, are further disaggregated by year of origination.

For BancShares, the standard will apply to loans, unfunded loan commitments and debt securities. A cross-functional team co-led by Corporate Finance and Risk Management is in place to implement the new standard. We have completed preliminary current expected credit losses (CECL) accounting interpretations, and continue to refine and test our models, estimation techniques, data, operational processes and controls to be used in preparing CECL loss estimates. During the remainder of 2019, we expect to address any gaps in our interpretations, including review of subsequent ASUs announced by the FASB regarding Topic 326, methodology, data and operational processes based upon our reviews and tests. BancShares continues to evaluate the impact of this standard on its consolidated financial statements but the magnitude of this impact has not been determined. The final impact will be dependent on, among other items, loan portfolio composition and credit quality at the adoption date, as well as economic conditions, financial models used and forecasts in place at that time.

The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018. BancShares will adopt the guidance in the first quarter of 2020 with a cumulative-effect adjustment to retained earnings as of the beginning of the year of adoption.

Investment Securities Maturity Information

The following table provides the amortized cost and fair value by contractual maturity for investment securities available for sale and held to maturity. Expected maturities will differ from contractual maturities on certain securities because borrowers and issuers may have the right to call or prepay obligations with or without prepayment penalties. Repayments of mortgage-backed securities are dependent on the repayments of the underlying loan balances, while repayments of certain corporate bonds are subject to call provisions that can be exercised by the issuer at their discretion.

As of June 30, 2019, there were 200 investment securities available for sale that had continuous losses for more than 12 months of which 197 were government sponsored enterprise-issued mortgage-backed securities or government agency securities, one was a U.S. Treasury security and two were corporate bonds.

None of the unrealized losses identified as of June 30, 2019 or December 31, 2018 relate to the marketability of the securities or the issuers' ability to honor redemption obligations. Rather, the unrealized losses relate to changes in interest rates relative to when the debt securities were purchased. BancShares has the ability and intent to retain these securities for a period of time sufficient to recover all unrealized losses. Therefore, none of the securities were deemed to be other than temporarily impaired.

Debt securities having an aggregate carrying value of $3.75 billion at June 30, 2019 and $4.03 billion at December 31, 2018 were pledged as collateral to secure public funds on deposit and certain short-term borrowings, and for other purposes as required by law.

We may be required to measure certain financial assets at fair value on a nonrecurring basis. These adjustments to fair value usually result from the application of lower of amortized cost or fair value accounting or write-downs of individual assets due to impairment.

Impaired loans are deemed to be at fair value if an associated allowance or current period charge-off has been recorded. The value of impaired loans is determined by either collateral valuations or discounted present value of the expected cash flow calculations. Collateral values are determined using appraisals or other third-party value estimates of the subject property with discounts generally between 6% and 11% applied for estimated selling costs and other external factors that may impact the marketability of the property. Expected cash flows are determined using expected payment information at the individual loan level, discounted using the effective interest rate. The effective interest rate generally ranges between 2% and 18%.

OREO acquired or written down within the previous 12 months is deemed to be at fair value. Asset valuations are determined by using appraisals or other third-party value estimates of the subject property with discounts generally between 6% and 11% applied for estimated selling costs and other external factors that may impact the marketability of the property. Changes to the value of the assets between scheduled valuation dates are monitored through continued communication with brokers and monthly reviews by the asset manager assigned to each asset. If there are any significant changes in the market or the subject property, valuations are adjusted or new appraisals ordered to ensure the reported values reflect the most current information.
