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 footnotes included in BancShares' Annual Report on Form 10-K for the year ended December 31, 2015.
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 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 reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates, and different assumptions in the application of these policies could result in material changes in BancShares' consolidated financial position, the consolidated results of operations or related disclosures. Material estimates that are particularly susceptible to significant change include:

• | Allowance for loan and lease losses

• | Fair value of financial instruments, including acquired assets and assumed liabilities

• | Pension plan assumptions

• | Cash flow estimates on purchased credit-impaired loans

• | Receivable from and payable to the FDIC for loss share agreements

• | Income tax assets, liabilities and expense

Recently Adopted Accounting Pronouncements
Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) 2015-16, Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments
This ASU eliminates the requirement to retrospectively account for adjustments made to provisional amounts recognized in a business combination and requires that an acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts must be calculated as if the accounting had been completed at the acquisition date.
The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years. The amendments in this ASU should be applied prospectively to adjustments to provisional amounts that occur after the effective date of this ASU with earlier application permitted for financial statements that have not been issued. We adopted the guidance effective in the first quarter of 2016. The initial adoption did not have an impact on our consolidated financial position or consolidated results of operations.

Table of Contents
FASB ASU 2015-03, Interest–Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs
This ASU simplifies the presentation of debt issuance costs by requiring that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of debt liability, consistent with debt discounts or premiums. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this update.
This ASU is effective for fiscal years beginning after December 15, 2015 for public business entities, including interim periods within those fiscal years, and is to be applied retrospectively. We adopted the guidance effective in the first quarter of 2016. The initial adoption did not have an impact on our consolidated financial position or consolidated results of operations.
FASB ASU 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis
This ASU improves targeted areas of consolidation guidance for reporting organizations that are required to evaluate whether they should consolidate certain legal entities. In addition to reducing the number of consolidation models from four to two, the new standard places more emphasis on risk of loss when determining a controlling financial interest, reducing the frequency of the application of related-party guidance when determining a controlling financial interest in a variable interest entity (VIE), and changing consolidation conclusions for public and private companies in several industries that typically make use of limited partnerships or VIEs.
The amendments in this ASU are effective for fiscal years beginning after December 15, 2015 for public business entities, including interim periods within those fiscal years. We adopted the guidance effective in the first quarter of 2016. The initial adoption did not have an impact on our consolidated financial position or consolidated results of operations.
Recently Issued Accounting Pronouncements
FASB ASU 2016-07, Investments—Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting
This ASU eliminates the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The ASU requires that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor's previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. Further, the ASU requires that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognizes through earnings, the unrealized gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method.
The amendments in this ASU are effective for all entities for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the impact of the new standard and will adopt the guidance during the first quarter of 2017.
FASB ASU 2016-06, Derivatives and Hedging (Topic 815): Contingent Put and Call Options in Debt Instruments
This ASU clarifies what steps are required when assessing whether the economic characteristics and risks of call (put) options are clearly and closely related to the economic characteristics and risks of their debt hosts, which is one of the criteria for bifurcating an embedded derivative. When a call (put) option is contingently exercisable, an entity does not have to assess whether the event that triggers the ability to exercise a call (put) option is related to interest rates or credit risks.
The amendments in the ASU are effective for public business entities for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. We will adopt the guidance during the first quarter of 2017. BancShares does not anticipate any effect on our consolidated financial position or consolidated results of options as a result of adoption.
FASB 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 existing standards and this ASU is the requirement for lessees to recognize on their balance sheet all lease contracts with lease terms greater than 12 months, including operating leases. Both a right-of-use asset, representing the right to use the leased asset, and a lease liability, representing the contractual obligation, are required to be recognized on the balance sheet of the lessee at lease commencement. Further, this ASU requires lessees to classify leases as either operating or finance leases, which are substantially similar to the current 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.
The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the impact of the new standard and we will adopt during the first quarter of 2019.
FASB ASU 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities
This ASU addresses certain aspects of recognition, measurement, presentation and disclosure. The amendments in this ASU (1) require equity investments to be measured at fair value with changes in fair value recognized in net income; (2) simplify the impairment assessment of equity investments without readily determinable fair value; (3) require public business entities to use exit prices, rather than entry prices, when measuring fair value of financial instruments for disclosure purposes; (4) require separate presentation of financial assets and financial liabilities by measurement category and form of financial assets on the balance sheet or the accompanying notes to the financial statements; (5) eliminate the requirement to disclose the method(s) and significant assumptions used to estimate the fair value for financial instruments measured at amortized cost on the balance sheet; (6) require separate presentation in other comprehensive income of the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the organization has elected to measure the liability at fair value in accordance with the fair value option for financial instruments; and (7) state that a valuation allowance on deferred tax assets related to available-for-sale securities should be evaluated in combination with other deferred tax assets.
The amendments in this ASU are effective for public business entities for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The ASU only permits early adoption of the instrument-specific credit risk provision. We are currently evaluating the impact of the new standard and we will adopt during the first quarter of 2018.
FASB ASU 2014-09, Revenue from Contracts with Customers (Topic 606)
In May 2014, the FASB issued a standard on the recognition of revenue from contracts with customers with the core principle being for companies to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. The new standard also results in enhanced disclosures about revenue, provides guidance for transactions that were not previously addressed comprehensively and improves guidance for multiple-element arrangements. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations, to improve the operability and understandability of the implementation guidance on principal versus agent considerations.
Per ASU 2015-14, Deferral of the Effective Date, this guidance was deferred and is effective for fiscal periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Early adoption is permitted for fiscal periods beginning after December 15, 2016. We are currently evaluating the impact of the new standard and we will adopt during the first quarter of 2018 using one of two retrospective application methods.
NOTE B - BUSINESS COMBINATIONS
North Milwaukee State Bank
On March 11, 2016, FCB entered into an agreement with the Federal Deposit Insurance Corporation (FDIC), as Receiver, to purchase certain assets and assume certain liabilities of North Milwaukee State Bank (NMSB) of Milwaukee, Wisconsin. The acquisition provided FCB with value enhancement.
The NMSB 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 $52.4 million, including $35.4 million in loans and $240 thousand of identifiable intangible assets. Liabilities assumed were $60.9 million of which $59.2 million were deposits. As a result of the transaction, FCB recorded a gain on the acquisition of $1.7 million which is included in noninterest income in the Consolidated Statements of Income.

Merger-related expenses of $38 thousand were recorded in the Consolidated Statements of Income for the three months ended March 31, 2016. Loan-related interest income generated from NMSB was approximately $123 thousand since the acquisition date.
All loans resulting from the NMSB transaction were recorded at the acquisition date with a discount attributable, at least in part, to credit quality, and are therefore accounted for as purchased credit-impaired (PCI) loans under ASC 310-30.

Investments in mortgage-backed securities primarily represent securities issued by the Government National Mortgage Association, Federal National Mortgage Association and Federal Home Loan Mortgage Corporation.The following table provides the amortized cost and fair value by contractual 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. Equity securities do not have a stated maturity date.

Investment securities with an aggregate fair value of $291.0 million and $280.1 million had continuous unrealized losses for more than 12 months with a corresponding aggregate unrealized loss of $2.3 million and $6.1 million as of March 31, 2016 and December 31, 2015, respectively. As of March 31, 2016, all 52 of these investments are government sponsored enterprise-issued mortgage-backed securities. None of the unrealized losses identified as of March 31, 2016 or December 31, 2015 relate to the marketability of the securities or the issuer’s ability to honor redemption obligations. Rather, the unrealized losses relate to changes in interest rates relative to when the investment securities were purchased. For all periods presented, BancShares had 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.
Investment securities having an aggregate carrying value of $4.94 billion at March 31, 2016 and $4.73 billion at December 31, 2015 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 purchased credit-impaired (PCI) or non-PCI. Non-PCI loans and leases include originated commercial, originated noncommercial, purchased non-impaired loans, purchased leases and certain purchased revolving credit. For purchased non-impaired loans to be included as non-PCI, it must be determined that the loans do not have a discount due, at least in part, to credit quality at the time of acquisition. Conversely, loans for which it is probable at acquisition that all required payments will not be collected in accordance with contractual terms are considered PCI loans. PCI loans are evaluated at acquisition and where a discount is required at least in part due to credit quality, the nonrevolving loans are accounted for under the guidance in ASC Topic 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality. PCI loans and leases are recorded at fair value at the date of acquisition. No allowance for loan and lease losses is recorded on the acquisition date as the fair value of the acquired assets incorporates assumptions regarding credit risk. An allowance is recorded if there is additional credit deterioration after the acquisition date.
BancShares reports PCI and non-PCI loan portfolios separately, and each portfolio is further divided into commercial and non-commercial based on the type of borrower, purpose, collateral, and/or our underlying credit management processes. Additionally, loans are assigned to loan classes, which further disaggregate loans based upon common risk characteristics.
Commercial – Commercial loans include construction and land development, mortgage, other commercial real estate, commercial and industrial, lease financing and other.
Construction and land development – Construction and land development consists of loans to finance land for development, investment, and use in a commercial business enterprise; multifamily apartments; and other commercial buildings that may be owner-occupied or income generating investments for the owner.
Commercial mortgage – Commercial mortgage consists of loans to purchase or refinance owner-occupied nonresidential and investment properties. Investment properties include office buildings and other facilities that are rented or leased to unrelated parties.
Other commercial real estate – Other commercial real estate consists of loans secured by farmland (including residential farms and other improvements) and multifamily (5 or more) residential properties.
Commercial and industrial – Commercial and industrial consists of loans or lines of credit to finance corporate credit cards, accounts receivable, inventory and other general business purposes.
Lease financing – Lease financing consists solely of lease financing agreements for business equipment, vehicles and other assets.
Other – Other consists of all other commercial loans not classified in one of the preceding classes. These typically include loans to non-profit organizations such as churches, hospitals, educational and charitable organizations.
Noncommercial – Noncommercial consist of residential and revolving mortgage, construction and land development, and consumer loans.
Residential mortgage – Residential real estate consists of loans to purchase, construct or refinance the borrower's primary dwelling, second residence or vacation home.
Revolving mortgage – Revolving mortgage consists of home equity lines of credit that are secured by first or second liens on the borrower's primary residence.
Construction and land development – Construction and land development consists of loans to construct the borrower's primary or secondary residence or vacant land upon which the owner intends to construct a dwelling at a future date.
Consumer – Consumer loans consist of installment loans to finance purchases of vehicles, unsecured home improvements and revolving lines of credit that can be secured or unsecured, including personal credit cards.

At March 31, 2016, $8.51 billion in noncovered loans with a lendable collateral value of $6.08 billion were used to secure $585.3 million in Federal Home Loan Bank (FHLB) of Atlanta advances, resulting in additional borrowing capacity of $5.50 billion. At December 31, 2015, $8.58 billion in noncovered loans with a lendable collateral value of $6.08 billion were used to secure $510.3 million in FHLB of Atlanta advances, resulting additional borrowing capacity of $5.57 billion.

Credit quality indicators
Loans and leases are monitored for credit quality on a recurring basis. The credit quality indicators used are dependent on the portfolio segment to which the loan relates. Commercial and noncommercial loans and leases have different credit quality indicators as a result of the unique characteristics of the loan segment 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. Each commercial loan is evaluated annually with more frequent evaluation of more severely criticized loans or leases. The credit quality indicators for non-PCI and PCI noncommercial loans are based on the delinquency status of the borrower. As the borrower becomes more delinquent, the likelihood of loss increases. The indicators represent the rating for loans or leases as of the date presented based on the most recent assessment performed. These credit quality indicators are defined as follows:
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 no 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 effected 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 March 31, 2016 and December 31, 2015 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 and other commercial real estate loans.

The aging of the outstanding non-PCI loans and leases, by class, at March 31, 2016 and December 31, 2015 is provided in the table below.
The calculation of days past due begins on the day after payment is due and includes all days through which all required interest or principal has not been paid. Loans and leases 30 days or less past due are considered current as various grace periods allow borrowers to make payments within a stated period after the due date and still remain in compliance with the loan agreement.

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 grant. Concessions may relate to the contractual interest rate, maturity date, payment structure or other actions. In accordance with GAAP, acquired loans accounted for under ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality, are not initially considered to be TDRs, but can be classified as such if a modification is made subsequent to acquisition. Subsequent modifications 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.
The following table provides a summary of total TDRs by accrual status.

The majority of TDRs are included in the special mention, substandard or doubtful grading categories. When a restructured loan subsequently defaults, it is evaluated and downgraded if appropriate. The more severely graded the loan, the lower the estimated expected cash flows and the greater the allowance recorded. Further, TDRs over $500,000 and graded substandard or lower are evaluated individually for impairment through a review of collateral values or analysis of cash flows.

NOTE G - FDIC LOSS SHARE RECEIVABLE
The following table provides changes in the receivable from the FDIC for the three months ended March 31, 2016 and March 31, 2015.

| Three months ended March 31
(Dollars in thousands) | 2016 |  | 2015
Beginning balance | $ | 4,054 |  |  | $ | 28,701 |
Amortization | (2,375 | ) |  | (5,031 | )
Net cash payments to FDIC | 9,871 |  |  | 5,762 |
Post-acquisition adjustments | (4,076 | ) |  | (8,092 | )
Ending balance | $ | 7,474 |  |  | $ | 21,340 |

The receivable from the FDIC for loss share agreements is measured separately from the related covered assets and is recorded at fair value at the acquisition date using projected cash flows based on the expected reimbursements for losses and the applicable loss share percentages. See Note L for information related to FCB's recorded payable to the FDIC for loss share agreements.
Amortization reflects changes in the FDIC loss share receivable due to improvements in expected cash flows that are being recognized over the remaining term of the loss share agreement. Cash payments to FDIC represent the net impact of loss share loan recoveries, charge-offs and related expenses as calculated and reported in FDIC loss share certificates. Post-acquisition adjustments represent the net change in loss estimates related to acquired loans and covered OREO as a result of changes in expected cash flows and the ALLL related to those covered loans. At the beginning of the second, third and fourth quarters of 2016, the loss share protection will expire for non-single family residential loans acquired from UWB, ABT and CCB, respectively. At December 31, 2016, loss share protection will have expired for all non-single family residential loans and loss share protection will remain only for single family residential loans acquired with loss share agreements.
NOTE H - MORTGAGE SERVICING RIGHTS
Our portfolio of residential mortgage loans serviced for third parties was $2.20 billion and $2.15 billion as of March 31, 2016 and December 31, 2015, respectively. These loans were originated by BancShares and sold to third parties on a non-recourse basis with servicing rights retained. These retained servicing rights are recorded as a servicing asset on the Consolidated Balance Sheets and are initially recorded at fair value.
The activity of the servicing asset for the three months ended March 31, 2016 and 2015 is presented in the following table:

| Three months ended March 31
(Dollars in thousands) | 2016 |  | 2015
Beginning balance | $ | 19,351 |  |  | $ | 16,688 |
Servicing rights originated | 977 |  |  | 662 |
Amortization | (1,268 | ) |  | (852 | )
Valuation allowance provision | (1,874 | ) |  | (62 | )
Ending balance | $ | 17,186 |  |  | $ | 16,436 |

The following table presents the activity in the servicing asset valuation allowance for the three months ended March 31, 2016 and 2015:

| Three months ended March 31
(Dollars in thousands) | 2016 |  | 2015
Beginning balance | $ | 95 |  |  | $ | 850 |
Valuation allowance provision | 1,874 |  |  | 62 |
Ending balance | $ | 1,969 |  |  | $ | 912 |

As of March 31, 2016, the carrying value of BancShares' mortgage servicing rights was $17.2 million. Contractually specified mortgage servicing fees, late fees, and ancillary fees earned for the three months ended March 31, 2016 and 2015 were $1.4 million and $1.3 million, respectively, and are included in mortgage income in the Consolidated Statements of Income.
The amortization expense related to mortgage servicing rights, included as a reduction of mortgage income in the Consolidated Statements of Income, was $1.3 million and $852 thousand for the three months ended March 31, 2016 and 2015, respectively.

Table of Contents
Mortgage income included an impairment of $1.9 million and $62 thousand for the three months ended March 31, 2016 and 2015, respectively.
Valuation of mortgage servicing rights is performed using a pooling methodology. Similar loans are pooled together and evaluated on a discounted earnings basis to determine the present value of future earnings. Key economic assumptions used to value mortgage servicing rights as of March 31, 2016 and December 31, 2015 were as follows:

| March 31, 2016 |  | December 31, 2015
Discount rate - conventional fixed loans | 8.77 | % |  | 9.31 | %
Discount rate - all loans excluding conventional fixed loans | 9.77 | % |  | 10.31 | %
Weighted average constant prepayment rate | 13.32 | % |  | 11.01 | %
Weighted average cost to service a loan | $ | 62.75 |  |  | $ | 56.61 |

NOTE I - REPURCHASE AGREEMENTS
BancShares utilizes securities sold under agreements to repurchase to facilitate the needs of customers and secure long-term funding needs. Repurchase agreements are transactions whereby BancShares offers to sell to a counterparty an undivided interest in an eligible security at an agreed upon purchase price, and which obligates BancShares to repurchase the security on an agreed upon date at an agreed upon repurchase price plus interest at an agreed upon rate. Securities sold under agreements to repurchase are recorded at the amount of cash received in connection with the transaction and are generally reflected as short-term borrowings on the Consolidated Balance Sheets.
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 segregate 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. The carrying value of available for sale investment securities pledged as collateral under repurchase agreements was $787.0 million and $722.0 million at March 31, 2016 and December 31, 2015, respectively.
The remaining contractual maturity of the securities sold under agreements to repurchase by class of collateral pledged included in the Consolidated Balance Sheets as of March 31, 2016 and December 31, 2015 is presented in the following tables.

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 to these valuation methods are subjective in nature, involve uncertainties and require significant judgment and therefore cannot be determined with precision. Accordingly, the derived fair value estimates presented below are not necessarily indicative of the amounts BancShares could 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 generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable 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.

Valuation adjustments, such as those pertaining to counterparty and BancShares' own credit quality and liquidity, may be necessary to ensure that assets and liabilities are recorded at fair value. Credit valuation adjustments are made when market pricing does not accurately reflect the counterparty's credit quality. As determined by BancShares management, liquidity valuation adjustments may be made to the fair value of certain assets to reflect the uncertainty in the pricing and trading of the instruments when we are unable to observe recent market transactions for identical or similar instruments.
BancShares management reviews any changes to its valuation methodologies to ensure they are appropriate and justified, 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. U.S.Treasury, government agency, mortgage-backed securities, municipal securities and trust preferred securities are generally measured at fair value using a third party pricing service or recent comparable market transactions in similar or identical securities and are classified as level 2 instruments. 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 on a heavily 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 are originated to be sold to investors, which are carried at fair value as BancShares elected the fair value option on loans held for sale. The fair value is based on quoted market prices for similar types of loans. Accordingly, the inputs used to calculate fair value of residential real estate loans held for sale are classified as level 2 inputs.
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. An additional valuation adjustment is made for liquidity. 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

Table of Contents
Mortgage servicing rights. Mortgage 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 asset cost. The fair value of mortgage 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 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.
Long-term obligations. For fixed rate trust preferred securities, the fair values are determined based on recent trades of the actual security if available. For other long-term obligations, 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 obligations are considered level 2 inputs.
Payable to the FDIC for loss share agreements. The fair value of the payable to the FDIC for loss share agreements is determined by the projected cash flows based on expected payments to the FDIC in accordance with the loss share 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.
Interest rate swap. Under the terms of the existing cash flow hedge, BancShares pays a fixed payment to the counterparty in exchange for receipt of a variable payment that is determined based on the three-month LIBOR rate. The fair value of the cash flow hedge is, therefore, based on projected LIBOR rates for the duration of the hedge, values that, while observable in the market, are subject to adjustment due to pricing considerations for the specific instrument. The inputs used in the fair value measurement of the interest rate swap are considered level 2 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 March 31, 2016 and December 31, 2015. 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, short-term borrowings and accrued interest payable are considered level 2. Lastly, the receivable from the FDIC for loss share agreements is designated as level 3.

Table of Contents
The changes in fair value for residential real estate loans held for sale for which we elected the fair value option are included in the table below for the three months ended March 31, 2016 and 2015.

| Three months ended March 31
(Dollars in thousands) | 2016 |  | 2015
Gains (losses) from fair value changes on loans held for sale | $ | 763 |  |  | $ | 430 |

The changes in fair value in the table above are recorded as a component of mortgage income on the Consolidated Statements of Income.
Certain other assets are adjusted to their fair value on a nonrecurring basis, including impaired loans, OREO, goodwill, which are periodically tested for impairment, and mortgage servicing rights, which are carried at the lower of amortized cost or market. Non-impaired loans held for investment, deposits, short-term borrowings and long-term obligations are not reported at fair value.
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 10 and 14 percent applied for estimated holding and 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 16 percent.
OREO is measured and reported at fair value using collateral valuations. Collateral values are determined using appraisals or other third-party value estimates of the subject property with discounts generally between 10 and 14 percent applied for estimated holding and 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. OREO that has been acquired or written down in the current year is deemed to be at fair value and included in the table below.
Mortgage servicing rights are carried at the lower of cost or market and are, therefore, carried at fair value only when fair value is less than the amortized asset cost. The fair value of mortgage servicing rights is performed using a pooling methodology. Similar loans are pooled together and a discounted cash flow model, which takes into consideration discount rates, prepayment rates, and the weighted average cost to service the loans, is used to determine the fair value.
For financial assets and liabilities carried at fair value on a nonrecurring basis, the following table provides fair value information as of March 31, 2016 and December 31, 2015.

No contributions were made during the three months ended March 31, 2016 to the BancShares or Bancorporation pension plans. BancShares does not expect to make any contributions to either of the defined benefit pension plans during 2016.
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, standby letters of credit and recourse obligations on mortgage loans sold. 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. At March 31, 2016, BancShares had unused commitments that were $8.08 billion, compared to $7.95 billion at December 31, 2015. Total unfunded commitments relating to investments in affordable housing projects was $58.1 million and $41.8 million at March 31, 2016 and December 31, 2015, respectively, and are included in other liabilities on BancShares' Consolidated Balance Sheets. Affordable housing project investments were $110.0 million and $85.6 million at March 31, 2016 and December 31, 2015, respectively, and are included in other assets on the Consolidated Balance Sheets.
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. To mitigate its risk, BancShares’ follows its credit policies in the issuance of standby letters of credit. At March 31, 2016 and December 31, 2015, BancShares had standby letters of credit amounting to $80.3 million and $77.9 million, respectively. 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.
Pursuant to standard representations and warranties relating to residential mortgage loan sales, contingent obligations exist for various events that may occur following the loan sale. If underwriting or documentation deficiencies are discovered at any point in the life of the loan or if the loan becomes nonperforming within 120 days of its sale, the investor may require BancShares to repurchase the loan or to repay a portion of the sale proceeds. Other liabilities included reserves of $3.0 million as of March 31, 2016 and December 31, 2015 for estimated losses arising from these standard representation and warranty provisions.

Table of Contents
BancShares has recorded a receivable from the FDIC totaling $7.5 million and $4.1 million as of March 31, 2016 and December 31, 2015, respectively, for the expected reimbursement of losses on assets covered under the various loss share agreements. These loss share agreements impose certain obligations on us that, in the event of noncompliance, could result in the delay or disallowance of some or all of our rights under those agreements. Requests for reimbursement are subject to FDIC review and may be delayed or disallowed for noncompliance. The loss share agreements are subject to interpretation by both the FDIC and BancShares, and disagreements may arise regarding coverage of losses, expenses and contingencies.
The loss share agreements for five 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. The clawback liability is estimated by discounting estimated future payments and is recorded in the Consolidated Balance Sheets as a payable to the FDIC under the relevant loss share agreements. As of March 31, 2016 and December 31, 2015, the estimated clawback liability was $128.2 million and $126.5 million, respectively.
BancShares and various subsidiaries have been named as defendants in legal actions arising from their normal business activities in which damages in various amounts are claimed. BancShares is also exposed to litigation risk relating to the prior business activities of banks from which assets were acquired and liabilities assumed in the various FDIC-assisted 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 M - DERIVATIVES
At March 31, 2016, BancShares had an interest rate swap entered into during 2011 that qualifies as a cash flow hedge under GAAP. For all periods presented, the fair value of the outstanding derivative is included in other liabilities in the consolidated balance sheets, and the net change in fair value is included in the consolidated statements of cash flows under the caption net change in other liabilities.
The following table provides the notional amount of the interest rate swap and the fair value of the liability as of March 31, 2016 and December 31, 2015.

| March 31, 2016 |  | December 31, 2015
(Dollars in thousands) | Notional amount |  | Estimated fair value of liability |  | Notional amount |  | Estimated fair value of liability
2011 interest rate swap hedging variable rate exposure on trust preferred securities 2011-2016 | $ | 93,500 |  |  | $ | 729 |  |  | $ | 93,500 |  |  | $ | 1,429 |

The interest rate swap is used for interest rate risk management purposes and converts variable-rate exposure on outstanding debt to a fixed rate. The interest rate swap has a notional amount of $93.5 million, representing the amount of variable rate trust preferred capital securities issued during 2006 and still outstanding at the swap inception date. The interest rate swap hedges interest payments through June 2016 and requires fixed-rate payments by BancShares at 5.50 percent in exchange for variable-rate payments of 175 basis points above the three-month LIBOR, which is equal to the interest paid to the holders of the trust preferred capital securities. Settlement of the swap occurs quarterly. The interest rate swap obligation did not meet the threshold to require pledged collateral to secure the obligation at March 31, 2016. At December 31, 2015, collateral with a fair value of $2.0 million was pledged to secure the existing obligation under the interest rate swap.
For cash flow hedges, the effective portion of the gain or loss due to changes in the fair value of the derivative hedging instrument is included in other comprehensive income, while the ineffective portion, representing the excess of the cumulative change in the fair value of the derivative over the cumulative change in expected future discounted cash flows on the hedged transaction, is recorded in the consolidated statement of income. BancShares’ interest rate swap has been fully effective since inception. Therefore, changes in the fair value of the interest rate swap have had no impact on net income. For the three months ended March 31, 2016 and 2015, BancShares recognized interest expense of $743 thousand and $826 thousand, respectively, resulting from incremental interest paid to the interest rate swap counterparty, none of which related to ineffectiveness.
BancShares monitors the credit risk of the interest rate swap counterparty.

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 2015 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 2016, the reclassifications had no material 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’ earnings and cash flows are primarily derived from 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.

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.
In March 2016, FCB entered into an agreement with the Federal Deposit Insurance Corporation (FDIC) to purchase certain assets and assume certain liabilities of North Milwaukee State Bank of Milwaukee, Wisconsin (NMSB). As a result of the NMSB transaction, FCB recorded loans with a fair value of $35.4 million and investment securities with a fair value of $9.4 million. The fair value of deposits assumed was $59.2 million. In accordance with the acquisition method of accounting, all assets and liabilities were recorded at their fair value as of the acquisition date. As a result, an acquisition gain of $1.7 million was recorded in the first quarter of 2016. Per the acquisition method of accounting, these fair values are preliminary and subject to refinement for up to one year after the acquisition date as additional information relative to closing date fair values become available.
Interest rates have presented significant challenges to commercial banks’ efforts to generate earnings and shareholder value. Management has embarked on several strategic initiatives to better position the company to counter these challenges. The initiatives focus on core revenue growth through broader products and services, control of noninterest expenses, optimization of our branch network, and further enhancements to our technology. Additionally, we continue to pursue strategic acquisitions and mergers to expand our customer base and increase efficiency and productivity. Refer to our Form 10-K for the year ended December 31, 2015 for further discussion of our strategy.
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. First quarter 2016 results indicate stable labor conditions despite global economic instability in recent months as the unemployment rate remained unchanged at 5.0 percent. According to the U.S. Department of Labor, the economy added approximately 628,000 new nonfarm payroll jobs during the first quarter of 2016 and labor force participation increased. The U.S. housing market experienced a slowdown of activity as a lack of available inventory of for-sale homes constrained many markets, although the outlook remains positive as a result of solid housing demand fueled by low mortgage interest rates, economic growth and job creation.
The Federal Reserve’s Federal Open Market Committee (FOMC) indicated in the first quarter that economic activity has been expanding at a moderate pace despite global economic and financial developments in recent months. Household spending has been increasing moderately and the housing sector shows further improvement, while business fixed investment and net exports have been soft. The FOMC decided to maintain the target range for the federal funds rate and will continue to assess realized and expected economic conditions relative to its objectives of maximum employment and 2.0 percent inflation in determining the timing and size of future adjustments to the target range. The FOMC anticipates that economic conditions will evolve in a manner that will warrant only gradual increases in the federal funds rate in the future.
The trends in the banking industry are similar to those of the broader economy as shown in the latest national banking results from the fourth quarter of 2015. FDIC-insured institutions reported an 11.9 percent increase in net income compared to the fourth quarter of 2014. Interest-earning assets contributed to an increase in net interest income compared to a year earlier and bank average net interest margin was 3.13 percent in the fourth quarter of 2015, up slightly from 3.12 percent in the fourth quarter of 2014. Banks minimally reduced their allowance for loan losses during the fourth quarter, as quarterly loan loss provisions exceeded quarterly net charge-offs for the first time in six years.
EARNINGS PERFORMANCE SUMMARY
BancShares' consolidated net income for the first quarter of 2016 was $52.1 million, or $4.34 per share, compared to $42.7 million, or $3.56 per share, for the fourth quarter of 2015, and $67.2 million, or $5.59 per share, for the corresponding period of 2015. BancShares’ current quarter results generated an annualized return on average assets of 0.66 percent and an annualized return on average equity of 7.17 percent, compared to respective returns of 0.53 percent and 5.92 percent for the fourth quarter of 2015 and 0.90 percent and 10.00 percent for the first quarter of 2015. Net interest margin for the first quarter of 2016 was 3.18 percent, compared to 3.12 percent for the fourth quarter of 2015 and 3.18 percent for the first quarter of the prior year.
Earnings for the first quarter of 2016 included an acquisition gain of $1.7 million recognized in connection with an FDIC-assisted transaction involving certain assets and liabilities assumed of North Milwaukee State Bank (NMSB) of Milwaukee, Wisconsin, acquired on March 11, 2016. The NMSB acquisition contributed $35.3 million in loans and $46.3 million in deposit balances at March 31, 2016. Earnings for the first quarter of 2015 included a $42.9 million gain on the February 13, 2015 acquisition of Capitol City Bank & Trust (CCBT).

Table of Contents
Key highlights in the first quarter of 2016 include:

• | Loans grew by $177.7 million to $20.42 billion during the first quarter of 2016, reflecting originated portfolio growth and the NMSB acquisition.

• | Deposits increased $434.5 million, or by 6.4 percent on an annualized basis, from December 31, 2015 primarily due to organic growth in low-cost demand deposit and savings accounts.

• | Net charge-offs were $4.3 million, or 0.08 percent of average loans and leases on an annualized basis, compared to $6.3 million, or 0.12 percent, during the fourth quarter of 2015.

• | The taxable-equivalent net interest margin increased by 6 basis points to 3.18 percent from the fourth quarter of 2015 due to originated loan growth and improvement in the overnight investment yield, partially offset by continued runoff of the purchased credit impaired (PCI) loan portfolio.

• | Noninterest income was $105.3 million and $99.1 million in the first quarter of 2016 and fourth quarter of 2015, respectively. The increase was driven primarily by investment securities gains of $4.6 million, lower adjustments to the FDIC receivable and the $1.7 million gain on the acquisition of NMSB in the current quarter.

• | BancShares remained well-capitalized under Basel III capital requirements with a Tier 1 risk-based capital ratio of 12.58 percent, common equity Tier 1 ratio of 12.58 percent, total risk-based capital ratio of 14.09 percent and leverage capital ratio of 9.00 percent at March 31, 2016.

BUSINESS COMBINATIONS
North Milwaukee State Bank
In March 2016, FCB entered into an agreement with the FDIC to purchase certain assets and assume certain liabilities of NMSB. The acquisition provided FCB with value enhancement. This is an FDIC-assisted transaction; however, it has no loss share agreement.
The NMSB 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 following table provides the identifiable assets acquired and liabilities assumed at their estimated fair values as of the acquisition date.

Merger-related expenses of $38 thousand were recorded in the Consolidated Statements of Income for the first quarter of 2016. Loan-related interest income generated from NMSB was approximately $123 thousand since the acquisition date.
All loans resulting from the NMSB transaction were recognized upon acquisition date with a discount attributable, at least in part, to credit quality, and are therefore accounted for as PCI loans.
FDIC-Assisted Transactions
BancShares completed seven FDIC-assisted transactions during the period beginning in 2009 through 2015, and it acquired NMSB in its eighth such transaction during the first quarter of 2016. These transactions provided us significant growth opportunities, have continued to provide significant contributions to our results of operations and have allowed us to increase our presence in existing markets and expand our banking presence to adjacent markets. Prior to its merger into BancShares, First Citizens Bancorporation, Inc. (Bancorporation) completed three FDIC-assisted transactions: Georgian Bank of Atlanta, Georgia (acquired in 2009); Williamsburg First National Bank of Williamsburg, South Carolina (acquired in 2010); and Atlantic Bank & Trust of Charleston, South Carolina (acquired in 2011). Nine of the eleven FDIC-assisted transactions (including the three completed by Bancorporation) included loss share agreements that, for their terms, protect us from a portion of the credit and asset quality risk we would otherwise incur. The CCBT and NMSB transactions did not include a loss share agreement.
For those acquired loans with loss share agreements, generally, losses on single family residential loans are covered for ten years. All other loans are generally covered for five years. At March 31, 2016, $258.2 million of total loans and leases remain covered under loss share agreements. At the beginning of the second, third and fourth quarters of 2016, the loss share protection will expire for non-single family residential loans acquired from United Western Bank (UWB), Atlantic Bank and Trust (ABT) and Colorado Capital Bank (CCB), respectively. The loan balances at March 31, 2016 for the expiring agreements from UWB, ABT and CCB were $113.7 million, $9.0 million and $2.7 million, respectively. At December 31, 2016, loss share protection

will have expired for all non-single family residential loans and loss share protection will remain only for single family residential loans acquired with loss share agreements. We will process all necessary filings in accordance with the agreements before expiration to collect the earned loss share receivables. Going forward, we will continue to manage these loans and loan relationships for which loss share has expired in accordance with our standard credit administration policies and procedures.

RESULTS OF OPERATIONS
Net Interest Income and Margin
First Quarter 2016
Net interest income was $232.7 million, an increase of $12.6 million, or by 5.7 percent, from the first quarter of 2015. On a taxable-equivalent basis, net interest income was $234.2 million, an increase of $12.7 million, or 5.8 percent, from the first quarter of 2015. Loan interest income increased $5.5 million from the first quarter of 2015 as a result of originated loan growth and investment securities interest income improved by $3.7 million as proceeds from sales and maturities were reinvested into higher yielding investments. Net interest income also benefited from higher income earned on overnight investments as a result of the December 2015 increase in the federal funds rate and lower interest expense due to reduced interest-bearing deposit costs. These favorable impacts were offset by lower PCI loan accretion income resulting from PCI loan portfolio runoff. Accretion income on PCI loans was $21.4 million, compared to $25.1 million during the first quarter of 2015.
Net interest income increased $2.0 million, or by 0.9 percent, to $232.7 million from the fourth quarter of 2015. On a taxable-equivalent basis, net interest income increased $2.0 million, or by 0.9 percent, from $232.1 million during the fourth quarter of 2015. The increase in net interest income primarily resulted from higher interest income earned on excess cash held in overnight investments of $1.6 million and lower interest expense of $750 thousand due to reduced borrowing and deposit funding costs. The December 2015 increase in federal funds rate of 25 basis points contributed to higher interest income earned on overnight investments. These favorable impacts were offset by lower PCI loan accretion income resulting from PCI loan portfolio runoff. Accretion income on PCI loans was $21.4 million, compared to $22.9 million during the fourth quarter of 2015.
Accretion income on acquired loans, which is included in interest income and includes accretion income on both PCI and non-PCI loans and leases, declined by $2.2 million and $6.1 million from the fourth quarter of 2015 and the first quarter of 2015, respectively, primarily due to the continued runoff of acquired loans. Non-PCI accretion income was $3.2 million, compared to $3.9 million and $5.6 million in the fourth quarter of 2015 and first quarter of 2015, respectively. The current quarter decrease from both periods relates to the continued runoff of non-PCI loans acquired in the Bancorporation merger.

The taxable-equivalent net interest margin increased 6 basis points to 3.18 percent in the first quarter of 2016, compared to the fourth quarter of 2015. The margin improvement was due to continued originated loan growth, improvement in investment yields and lower borrowing costs, partially offset by PCI loan portfolio runoff. The December 2015 increase in federal funds rate of 25 basis points contributed to higher interest income earned on overnight investments. The taxable equivalent net interest margin was unchanged from 3.18 percent from the same quarter in the prior year.
Average quarter-to-date interest earning assets decreased by $7.1 million since the fourth quarter of 2015, reflecting a $220.9 million decline in average investment securities and a reduction in average overnight investments of $75.7 million. These decreases were partially offset by a $289.5 million increase in average outstanding loans due to originated loan growth. Average investment securities declined as sales, maturities and paydowns exceeded purchases during the quarter. Average quarter-to-date interest earning assets increased by $1.33 billion compared to the same quarter in the prior year. Growth in average interest-earning assets was primarily funded by growth in deposits. Within interest-earning assets, loans experienced the most significant increase, primarily due to originated loan growth.
Average interest-bearing liabilities increased by $133.8 million compared to the fourth quarter of 2015, due to a $161.2 million increase in average interest-bearing deposits and a $46.0 million increase in average long-term obligations, partially offset by a $73.4 million decline in average short-term borrowings. The decline in short-term borrowings was due to a reduction in average repurchase obligations, while the increase in long-term obligations was due to the addition of $75.0 million Federal Home Loan Bank (FHLB) advances during the first quarter of 2016 to mitigate interest rate risk from long-term fixed rate loans. When compared to the same quarter in the prior year, average interest-bearing liabilities decreased $104.7 million and the rate on interest-bearing liabilities decreased 2 basis points to 0.22 percent. The decline in the rate on interest-bearing liabilities was the result of lower borrowings levels and funding costs in the first quarter of 2016.
Noninterest Income
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 have traditionally consisted of cardholder services income, merchant services income, service charges on deposit accounts and revenues derived from wealth management services. Recoveries on PCI loans that have been previously charged-off are additional sources of noninterest income. BancShares records the portion of recoveries not covered under loss share agreements as noninterest income rather than as an adjustment to the allowance for loan losses since charge-offs on PCI loans are recorded against the discount recognized on the date of acquisition versus the allowance for loan losses.

Total noninterest income | $ | 105,282 |  |  | $ | 99,135 |  |  | $ | 150,753 |

In the first quarter of 2016, noninterest income was $105.3 million, an increase of $6.1 million from the fourth quarter of 2015. The change from the fourth quarter of 2015 was attributable to the following drivers:

• | Gains on sales of investment securities were $4.6 million triggered in response to changing market conditions and to better position the investment portfolio for a rising rate environment.

Table of Contents

• | Lower FDIC receivable adjustments of $6.7 million resulting from net losses on sales of covered other real estate owned (OREO) in the current quarter.

• | The $1.7 million gain on acquisition of NMSB in the current quarter.

• | Recoveries of PCI loans previously charged off declined $2.3 million.

• | Mortgage income declined $1.9 million due to a $1.9 million impairment charge on mortgage servicing assets driven by a decline in interest rates during the quarter.

Noninterest income excluding acquisition gains decreased by $4.2 million from the same quarter in the prior year. The decrease was primarily driven by a $3.2 million decline in mortgage income due to declines in interest rates, a $2.6 million decrease in recoveries of PCI loans previously charged-off, higher unfavorable adjustments to the FDIC receivable of $1.5 million, and a decline in wealth management income of $1.2 million. The decreases were partially offset by a $3.1 million increase in merchant income due to higher sales volumes.
Noninterest Expense
The primary components of noninterest expense are salaries and related employee benefits, occupancy costs, facilities and equipment expense and merchant processing expenses.

Total noninterest expense | $ | 251,671 |  |  | $ | 255,886 |  |  | $ | 258,166 |

Noninterest expense was $251.7 million in the first quarter of 2016, a decline of $4.2 million from the fourth quarter of 2015. The following items impacted various noninterest expense categories:

• | Merger-related expenses declined $2.9 million primarily due to costs associated with the Bancorporation merger.

• | Advertising costs decreased by $2.7 million primarily as a result of a corporate sponsorship campaign in the fourth quarter of 2015.

• | Personnel expenses declined $1.1 million primarily due to one additional business day in the fourth quarter of 2015 and higher deferrals of salary costs related to loan origination activity.

• | Equipment expense decreased $1.0 million primarily due to a reduction in depreciation and maintenance expense.

• | Foreclosure-related expenses increased $3.7 million primarily due to a net loss on sales of acquired OREO during the current quarter.

Noninterest expense decreased $6.5 million in the first quarter of 2016 from $258.2 million in the first quarter of 2015. The decrease was due to a decline in personnel expenses of $5.4 million related to lower pension and higher deferrals of salary costs

for loan originations and $3.0 million decrease in merger-related expenses. These declines were partially offset by a $1.2 million increase in merchant processing and $1.1 million increase in card processing expenses due to higher sales volumes.
Income Taxes
Income tax expense was $29.4 million, $24.2 million and $39.8 million for the first quarter of 2016, fourth quarter of 2015 and first quarter of 2015, representing effective tax rates of 36.1 percent, 36.1 percent and 37.2 percent during the respective periods. The higher effective tax rate for the first quarter of 2015 was primarily attributable to increased pre-tax earnings as a result of the CCBT acquisition gain.
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 loans and leases, investment securities, 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 have historically focused on maintaining high-asset quality, which results in a loan and lease portfolio subjected to strenuous underwriting and monitoring procedures. We avoid high-risk industry concentrations, but we do maintain a concentration of owner-occupied real estate loans to borrowers in medical and medical-related fields. Our focus on asset quality also influences the composition of our investment securities portfolio.
Interest-earning assets averaged $29.56 billion and $29.57 billion for the quarter ended March 31, 2016 and December 31, 2015, respectively. The $7.1 million decline from December 31, 2015 was due to a $296.6 million decline in investment securities and overnight investments, partially offset by a $289.5 million increase in loans and leases as a result of originated loan growth.
Investment Securities
Investment securities were $6.69 billion at March 31, 2016, compared to $6.86 billion and $7.05 billion at December 31, 2015 and March 31, 2015, respectively. The $174.0 million and $357.8 million decrease in the portfolio from December 31, 2015 and March 31, 2015, respectively, was attributable to reinvesting a portion of the proceeds from sales, maturities and calls into overnight investments pending reinvestment. The yield on overnight investments benefited from the December 2015 increase in the federal funds rate of 25 basis points.
Available for sale securities are reported at fair value and unrealized gains and losses are included as a component of other comprehensive income, net of deferred taxes. As of March 31, 2016, investment securities available for sale had a net pre-tax unrealized gain of $38.9 million, compared to a net pre-tax unrealized loss of $24.5 million as of December 31, 2015 and a net unrealized gain of $33.6 million as of March 31, 2015. After evaluating the securities with unrealized losses, management concluded that no other than temporary impairment existed as of March 31, 2016.
At March 31, 2016, mortgage-backed securities represented 70.7 percent of investment securities available for sale, compared to U.S. Treasury, government agency securities, equity securities and other, which represented 23.0 percent, 5.3 percent, 0.8 percent and 0.2 percent of the portfolio, respectively. Overnight investments are with the Federal Reserve Bank and other financial institutions.
Since December 31, 2015, cash flows from the sales, maturities and calls of U.S. Treasury and government agency securities were reinvested into mortgage-backed securities and equity securities in order to optimize earnings and manage overall risk of the investment portfolio. As a result, the carrying value of mortgage-backed securities issued by government sponsored enterprises and equity securities increased by $59.1 million and $43.2 million, respectively, while U.S. Treasury securities decreased $133.7 million and government agency securities declined $142.5 million.
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. Changes in the total balance of our investment securities portfolio result from trends among loans and leases, deposits and short-term borrowings. 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.

Loans and Leases
Loans were $20.42 billion at March 31, 2016, a net increase of $177.7 million compared to December 31, 2015, representing growth of 3.5 percent on an annualized basis. Originated loans increased by $182.3 million primarily due to continued commercial portfolio growth. PCI loans decreased by $4.6 million, reflecting loan runoff of $39.9 million, partially offset by net loans acquired from NMSB of $35.3 million at March 31, 2016.
Non-PCI loans increased by $1.63 billion, compared to March 31, 2015, reflecting originated loan growth. PCI loans decreased by $306.7 million from March 31, 2015, due to continued pay downs in the PCI loan portfolio, offset by the contribution from the NMSB acquisition.
BancShares reports PCI and non-PCI loan portfolios separately and each portfolio is further divided into commercial and non-commercial. Additionally, loans are assigned to loan classes, which further disaggregate loans based upon common risk characteristics, such as commercial real estate, commercial and industrial or residential mortgage. Table 8 provides the composition of PCI and non-PCI loans and leases.
PCI Loans
The PCI portfolio includes loans acquired in a transfer, including business combinations, where there is evidence of credit
deterioration since origination and it is probable at the date of acquisition that we will not collect all contractually required
principal and interest payments. All nonrevolving loans are evaluated at acquisition and where a discount is required at least in part due to credit quality, the loans are accounted for under the guidance in ASC Topic 310-30. PCI loans and leases are valued at fair value at the date of acquisition.
PCI loans at March 31, 2016 were $945.9 million, representing 4.6 percent of total loans and leases, compared to $950.5 million and $1.25 billion at December 31, 2015 and March 31, 2015, respectively.
PCI commercial loans were $594.2 million at March 31, 2016, an increase of $613 thousand since December 31, 2015 and a decrease of $201.8 million since March 31, 2015. At March 31, 2016, PCI noncommercial loans were $351.7 million, a decrease of $5.2 million and $104.8 million since December 31, 2015 and March 31, 2015, respectively. The runoff in the PCI loan portfolio was offset by the contribution from the NMSB acquisition.

Non-PCI Loans and Leases
The non-PCI portfolio includes loans that management has the intent and ability to hold and is reported at the principal balance
outstanding, net of deferred loan fees and costs. Non-PCI loans include originated commercial loans and leases, originated noncommercial loans, purchased non-impaired loans, purchased leases and certain purchased revolving credit. For purchased non-impaired loans to be included as non-PCI, it must be determined that the loans do not have a discount at least in part due to credit quality at the time of acquisition. Purchased non-impaired loans are initially recorded at their fair value at the date of acquisition.
Non-PCI loans at March 31, 2016 were $19.47 billion, representing 95.4 percent of total loans and leases, compared to $19.29 billion and $17.84 billion at December 31, 2015 and March 31, 2015, respectively.
The non-PCI commercial loan portfolio is composed of Commercial Mortgage, Commercial and Industrial, Construction and Land Development, Lease Financing, Other Commercial Real Estate and Other Commercial loans. Non-PCI commercial loans were $12.79 billion at March 31, 2016, an increase of $159.4 million and $1.30 billion, compared to December 31, 2015 and March 31, 2015, respectively, resulting from continued loan growth.
The non-PCI noncommercial loan portfolio is composed of Residential Mortgage, Revolving Mortgage, Consumer and Construction and Land Development loans. Non-PCI noncommercial loans were $6.68 billion at March 31, 2016, an increase of $22.9 million and $330.9 million compared to December 31, 2015 and March 31, 2015, respectively.

Allowance for Loan and Lease Losses (ALLL)
The ALLL was $206.8 million at March 31, 2016, representing increases of $567 thousand and $1.2 million since December 31, 2015 and March 31, 2015, respectively. The increase in the ALLL for non-PCI loans and leases, primarily due to loan growth, offset the continued reduction in the ALLL for PCI loans due to portfolio runoff. The ALLL as a percentage of total loans and leases was 1.01 percent at March 31, 2016, compared to 1.02 percent and 1.08 percent at December 31, 2015 and March 31, 2015, respectively. The decline in the ALLL ratio from December 31, 2015 was primarily due to lower reserves on PCI loans due to runoff in the portfolio. The decline in the ALLL ratio from March 31, 2015 was due to credit quality improvements and lower reserves on PCI loans due to portfolio runoff.
At March 31, 2016, the ALLL allocated to non-PCI loans and leases was $193.0 million, or 0.99 percent of non-PCI loans and leases, compared to $189.9 million, or 0.98 percent, at December 31, 2015 and $187.9 million, or 1.05 percent, at March 31, 2015. An additional ALLL of $13.8 million relates to PCI loans at March 31, 2016, compared to $16.3 million and $17.6 million at December 31, 2015 and March 31, 2015, respectively. The ALLL on the PCI loan portfolio continues to decline consistent with the runoff of this portfolio.
The ALLL allocated to originated non-PCI loans and leases was 1.14 percent of originated non-PCI loans and leases at March 31, 2016, unchanged from December 31, 2015 and compared to 1.32 percent at March 31, 2015. Originated non-PCI loans were $16.98 billion, $16.60 billion and $14.29 billion at March 31, 2016, December 31, 2015 and March 31, 2015, respectively, and do not include purchased revolving, purchased non-PCI loans or PCI loans.
BancShares continues to experience improved credit quality indicators which have reduced the ALLL ratio since March 31, 2015. In the commercial non-PCI loan portfolio, credit quality improvements included low net charge-off ratios and migration of loans with higher credit risk ratings to lower ratings. The noncommercial non-PCI loan portfolio also experienced lower delinquency trends. Additionally, impaired non-PCI loan reserves have been lower due to improved cash flow and higher collateral values for impaired loans.
BancShares recorded $4.8 million net provision expense for loan and lease losses during the first quarter of 2016, compared to net provision expense of $7.0 million in the fourth quarter of 2015. The decline of $2.2 million was due to lower net charge-offs on non-PCI loans and leases and higher impairment reversals on PCI loans. Compared to the first quarter of 2015, provision expense decreased $949 thousand due primarily to lower originated loan growth, partially offset by lower impairment reversals on PCI loans. On an annualized basis, total net charge-offs as a percentage of total average loans and leases decreased during the first quarter of 2016 to 0.08 percent, compared to 0.12 percent in the fourth quarter of 2015 and 0.10 percent in the first quarter of 2015.
Provision expense for non-PCI loan and leases was $6.8 million during the first quarter of 2016, compared to $7.9 million in the fourth quarter of 2015, a decline of $1.1 million primarily due to lower loan growth and net charge-offs. Compared to the first quarter of 2015, provision expense decreased $1.8 million primarily due to lower loan growth. Net charge-offs for non-PCI loans and leases were $3.7 million during the first quarter of 2016, compared to $6.0 million and $3.6 million during the fourth quarter of 2015 and first quarter of 2015, respectively. On an annualized basis, non-PCI net charge-offs as a percentage of non-PCI average loans and leases during the first quarter of 2016 were 0.08 percent, down from 0.12 percent during the fourth quarter of 2015 and unchanged from the first quarter of 2015.
The PCI loan net provision credit was $2.0 million during the first quarter of 2016, compared to net provision credits of $903 thousand and $2.9 million for the fourth quarter of 2015 and first quarter of 2015, respectively.
Management considers the ALLL adequate to absorb estimated inherent losses that relate to loans and leases outstanding at March 31, 2016, although future adjustments may be necessary based on changes in economic conditions and other factors. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the ALLL. Such agencies may require adjustments to the ALLL based on information available to them at the time of their examination.

The provision expense for commercial mortgage non-PCI loans and leases was $394 thousand for the three months ended March 31, 2016, compared to a net provision credit of $3.7 million for the same period of 2015. The increase in provision expense was primarily due to higher loan growth in 2016 compared to the prior year.
Other commercial real estate non-PCI loans and leases had a net provision credit of $104 thousand for the three months ended March 31, 2016, compared to provision expense of $458 thousand for the same period of 2015. The decline in provision was due to lower net charge-offs during the current quarter.
The provision expense for commercial and industrial non-PCI loans and leases was $2.2 million for the three months ended March 31, 2016, compared to provision expense of $7.5 million for the same period of 2015. The decrease in provision expense was due to lower loan growth and net charge-offs in 2016 compared to 2015.

The following non-GAAP reconciliation in Table 11 provides a calculation of the adjusted ALLL and the related adjusted ALLL as a percentage of total loans and leases for the periods presented. Management uses these non-GAAP financial measures to monitor performance and believes this measure provides meaningful information as the remaining unamortized discounts provide coverage for losses similar to the ALLL. Non-GAAP financial measures have limitations as analytical tools, and should not be considered in isolation or as a substitute for analysis of BancShares' results or financial condition as reported under GAAP.

The adjusted ALLL (non-GAAP), which includes the ALLL as well as remaining net acquisition fair value adjustments for acquired loans, declined to 1.89 percent of total loans and leases at March 31, 2016, from 1.90 percent and 2.40 percent of total loans and leases at December 31, 2015 and March 31, 2015, respectively. The reduction in the adjusted ALLL resulted primarily from credit quality improvements and continued accretion of acquisition accounting fair value adjustments.
Nonperforming Assets
Nonperforming assets include nonaccrual loans and leases and OREO resulting from both PCI and non-PCI loans. At March 31, 2016, BancShares’ nonperforming assets were $162.8 million, a decline of $6.2 million and $20.1 million from December 31, 2015 and March 31, 2015, respectively, related to overall reductions in OREO balances and nonaccrual loans and leases.
OREO balances have declined $491 thousand and $24.9 million since December 31, 2015 and March 31, 2015, respectively, primarily due to sales and write-downs outpacing new additions. Nonaccrual PCI loans at March 31, 2016 are down $260 thousand and $19.6 million from December 31, 2015 and March 31, 2015, respectively, due to resolutions of impaired loans. Nonaccrual non-PCI loans and leases at March 31, 2016 have declined $5.4 million from December 31, 2015 as a result of problem asset resolutions primarily in the commercial loan portfolio, while nonaccrual non-PCI loans and leases increased $24.4 million from March 31, 2015 due to the downgrade of a few large commercial mortgage relationships and an increase in residential mortgage loans being placed on nonaccrual status.
Of the $162.8 million in nonperforming assets at March 31, 2016, $12.7 million related to loans and OREO covered by loss share agreements. Covered nonperforming assets continue to decline due to the expiration of FDIC loss share agreements and loan resolutions; however, covered OREO increased $2.9 million from December 31, 2015 as a result of a large covered commercial loan relationship moving to OREO during the current quarter.

Troubled Debt Restructurings
Troubled debt restructurings (TDRs) are selectively made to provide relief to customers experiencing liquidity challenges or other circumstances that could affect their ability to meet their debt obligations. Typical modifications include short-term deferral of interest or modification of payment terms. Nonperforming TDRs are not accruing interest and are included as nonperforming assets within nonaccrual loans and leases. TDRs which are accruing at the time of restructure and continue to perform based on the restructured terms are considered performing.
Total PCI and non-PCI loans and leases classified as TDRs at March 31, 2016 were $141.4 million, compared to $144.8 million at December 31, 2015 and $157.0 million at March 31, 2015. Accruing TDRs were $113.7 million, an increase of $433 thousand and a decrease of $17.7 million from December 31, 2015 and March 31, 2015, respectively. At March 31, 2016, nonaccruing TDRs were $27.7 million, a decrease of $3.9 million and an increase of $2.1 million from December 31, 2015 and March 31, 2015, respectively. The decrease in nonaccruing TDRs from December 31, 2015 was primarily related to large payoffs in the commercial loan portfolio.

INTEREST-BEARING LIABILITIES
Interest-bearing liabilities include interest-bearing deposits, short-term borrowings and long-term obligations. Interest-bearing liabilities were $19.17 billion and $18.96 billion at March 31, 2016 and December 31, 2015, respectively. The $217.0 million increase from December 31, 2015 was due to $75.0 million of new Federal Home Loan Bank (FHLB) borrowings during the quarter, a $94.5 million increase in repurchase agreements and organic growth in interest-bearing deposits of $47.5 million. Interest-bearing liabilities decreased $54.5 million from March 31, 2015 primarily due to a $112.8 million reduction in interest-bearing deposits, subordinated debt maturities of $199.9 million, maturities of FHLB advances of $10.0 million and a $42.7 million reduction in repurchase agreements. These decreases were partially offset by $305.0 million in additional FHLB borrowings.
Deposits
At March 31, 2016, total deposits were $27.37 billion, an increase of $434.5 million, or 1.61 percent, when compared to December 31, 2015 due to organic growth in low-cost demand deposit and savings accounts. Deposits increased $1.06 billion, or by 4.0 percent, when compared to March 31, 2015, primarily the result of organic growth in demand deposit, checking with interest and savings accounts.
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 dependent on our success at retaining existing deposits and generating new deposits at a reasonable cost.
Short-Term Borrowings
At March 31, 2016, short-term borrowings were $689.2 million compared to $594.7 million and $941.9 million at December 31, 2015 and March 31, 2015, respectively. The $94.5 million increase from December 31, 2015 was due to higher activity in customer repurchase agreements. The $252.6 million decrease from March 31, 2015 was due to maturities of FHLB borrowings of $10.0 million, maturities of subordinated debt of $199.9 million and a $42.7 million reduction in customer repurchase agreements.
Long-Term Obligations
Long-term obligations were $779.1 million at March 31, 2016, up $74.9 million from December 31, 2015 primarily the result of incremental FHLB borrowings of $75.0 million during 2016 to mitigate interest rate risk from long-term fixed rate loans. Long-term obligations were up $310.9 million from March 31, 2015 primarily due to new FHLB borrowings of $305.0 million since March 31, 2015.
At March 31, 2016, December 31, 2015 and March 31, 2015, long-term obligations included $132.5 million in junior subordinated debentures representing obligations to FCB/NC Capital Trust III, FCB/SC Capital Trust II, and SCB Capital Trust I, special purpose entities and grantor trusts for $128.5 million of trust preferred securities. FCB/NC Capital Trust III, FCB/SC Capital Trust II, and SCB Capital Trust I's (the Trusts) trust preferred securities mature in 2036, 2034, and 2034, respectively, and may be redeemed at par in whole or in part at any time. BancShares has guaranteed all obligations of the Trusts.

Shareholders' Equity and Capital Adequacy
BancShares and FCB are required to meet minimum capital requirements imposed by regulatory authorities. Failure to meet certain capital requirements may result in actions by regulatory agencies that could have a material impact on our consolidated financial statements.
In accordance with accounting principles generally accepted in the United States of America (GAAP), unrealized gains and losses on certain assets and liabilities, net of deferred taxes, are included in accumulated other comprehensive income (AOCI)within shareholders' equity. These amounts are excluded from shareholders' equity in the calculation of our capital ratios. In the aggregate, these items represented a net reduction in shareholders' equity of $23.8 million at March 31, 2016, compared to a net reduction of $64.4 million at December 31, 2015 and a net reduction of $35.4 million at March 31, 2015. The $40.6 million change in AOCI from December 31, 2015 was primarily driven by an increase in unrealized gains on investment securities available for sale. The $11.6 million change in AOCI from March 31, 2015 was driven by the increase in unrealized gains on investment securities available for sale and the change in the funded status of the defined benefit plans.

Bank regulatory agencies approved regulatory capital guidelines (Basel III) aimed at strengthening existing capital requirements for banking organizations. The final rules set new minimum requirements for both the quantity and quality of capital held by BancShares and included a new common equity Tier 1 capital to risk-weighted assets ratio. A new capital conservation buffer was also established and was phased in beginning January 1, 2016 at 0.625 percent of risk-weighted assets and will increase each subsequent year by an additional 0.625 percent until reaching its final level of 2.50 percent on January 1, 2019. BancShares and FCB had capital conservation buffers above minimum risk-based capital requirements of 6.09 percent and 5.32 percent, respectively, at March 31, 2016. The buffers exceed the 0.625 percent requirement and, therefore, result in no limit on distributions.
As of March 31, 2016, BancShares continues to exceed minimum capital standards and FCB remains well-capitalized under the new rules. BancShares remained well capitalized with a leverage capital ratio of 9.00 percent, Tier 1 risk-based capital ratio of 12.58 percent, common equity Tier 1 ratio of 12.58 and total risk-based capital ratio of 14.10 percent under Basel III guidelines at March 31, 2016.
BancShares had no trust preferred capital securities included in Tier 1 capital at March 31, 2016, compared to $32.1 million at December 31, 2015. The decrease during 2016 was due to the implementation of Basel III. Effective January 1, 2015, 75 percent of our trust preferred capital securities were excluded from Tier 1 capital and the remaining 25 percent were phased out on January 1, 2016 under Basel III requirements. Trust preferred capital securities continue to be a component of total risk-based capital.
RISK MANAGEMENT
Risk is inherent in any business and, as is the case with other management functions, senior management has primary responsibility for day-to-day management of the risks we face. The Board of Directors strive to ensure that risk management is part of the business culture and that policies and procedures for assessing, monitoring, and limiting risk are part of the daily decision-making process. The Board of Director’s role in risk oversight is an integral part of our overall enterprise risk

Table of Contents
management framework. The Board of Directors administers its risk oversight function primarily through committees which may be established as separate or joint committees of the board, including a joint Risk Committee that oversees enterprise-wide risk management.
The Risk Committee structure is designed to allow for information flow and escalation of risk related issues. Among the duties and responsibilities as may be assigned from time to time by the Board of Directors, the Risk Committee is directed to monitor and advise the board regarding risk exposures, including credit, market, liquidity, operational, compliance, legal, strategic and reputational risks; review, approve and monitor adherence to risk appetite and supporting risk tolerance levels; evaluate, monitor and oversee the adequacy and effectiveness of the risk management framework; and review reports of examination by and communications from regulatory agencies, and the results of internal and third party testing, analyses and reviews, related to risks, risk management, and any other matters within the scope of the Risk Committee’s oversight responsibilities, and monitor and review management’s response to any noted issues. In addition, the Risk Committee may coordinate with the Audit Committee for the review of financial statements and related risks and other areas of joint responsibility.
The Dodd-Frank Act mandated that stress tests be developed and performed to ensure that financial institutions have sufficient capital to absorb losses and support operations during multiple economic and bank scenarios. Bank holding companies with total consolidated assets between $10 billion and $50 billion, including BancShares, will undergo annual company-run stress tests. As directed by the Federal Reserve, summaries of BancShares’ results in the severely adverse stress tests are available to the public. In combination with other risk management and monitoring practices, the results of stress testing activities will be considered as part of our risk management program.
Credit risk management. Credit risk is the risk of not collecting payments pursuant to the contractual terms of loans, leases and investment securities. Loans and leases, other than acquired loans, were underwritten in accordance with our credit policies and procedures and are subject to periodic ongoing reviews. Acquired loans were 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 acquired and originated loans to ensure compliance with credit policies and to monitor asset quality trends. The risk 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 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, from assets and liabilities repricing at the same point in time but in different amounts and from 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 forecast net interest income assuming stable rates. Rate shock scenarios represent an instantaneous and parallel shift in rates, up or down, from a base yield curve. Due to the current low level of interest rates and competitive pressures that constrain our ability to further reduce deposit interest rates, it is unlikely that the rates on most interest-bearing liabilities can decline materially from current levels. Our shock projections incorporate assumptions of likely customer migration of low rate deposit instruments to intermediate term fixed rate instruments, such as certificates of deposit, as rates rise. Various other IRR scenarios are modeled to supplement shock scenarios. This may include interest rate ramps, changes in the shape of the yield curve and changes in the relationships of FCB rates to market rates.
Table 15
Net Interest Income Sensitivity Simulation Analysis
This table provides the impact on net interest income over 24 months resulting from various instantaneous interest rate shock scenarios as of March 31, 2016 and December 31, 2015.

| Estimated increase (decrease) in net interest income
Change in interest rate (basis point) | March 31, 2016 |  | December 31, 2015
+100 | 4.20 | % |  | 2.78 | %
+200 | 5.21 |  |  | 2.80 |
+300 | 2.01 |  |  | (0.75 | )

The change in net interest income sensitivity metrics at March 31, 2016 compared to December 31, 2015 was primarily due to a decrease in intermediate and long-term treasury and swap rates which resulted in a change to the expected deposit mix.

Table 16
Economic Value of Equity Modeling Analysis
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. This table presents the EVE profile as of March 31, 2016 and December 31, 2015.

| Estimated increase (decrease) in EVE
Change in interest rate (basis point) | March 31, 2016 |  | December 31, 2015
+100 | 5.39 | % |  | 3.18 | %
+200 | 5.25 |  |  | 1.53 |
+300 | 0.16 |  |  | (3.92 | )

The improvement in the economic value of equity metrics at March 31, 2016 compared to December 31, 2015 was primarily due a decrease in intermediate and long-term treasury and swap rates which had a favorable impact on deposits and EVE risk.
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. However, we have entered into an interest rate swap to synthetically convert the variable rate on $93.5 million of junior subordinated debentures to a fixed rate of 5.50 percent through June 2016. The interest rate swap qualifies as a hedge under GAAP. See Note M to the Consolidated Financial Statements, "Derivatives," for additional discussion of this interest rate swap.
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 deposits (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, operation, 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 sources of liquidity are our retail deposit book due to the generally stable balances and low cost it offers, cash in excess of our reserve requirement at the Federal Reserve Bank and various other corresponding bank accounts and unencumbered securities, all of which were $4.24 billion at March 31, 2016 compared to $3.96 billion at December 31, 2015. Another source of available funds is advances from the FHLB of Atlanta. Outstanding FHLB advances were $595.2 million as of March 31, 2016, and we had sufficient collateral pledged to secure $5.50 billion of additional borrowings. We also maintain Federal Funds lines and other borrowing facilities which had $790.0 million of available capacity at March 31, 2016.

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 March 31, 2016, BancShares’ market risk profile has not changed significantly from December 31, 2015, 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 change in BancShares' internal control over financial reporting occurred during the first quarter of 2016 that had materially affected, or is reasonably likely to materially affect, BancShares' internal control over financial reporting.
