Accounting Policies [Abstract]
Accounting Policies and Basis of Presentation	ACCOUNTING POLICIES AND BASIS OF PRESENTATION First Citizens BancShares, Inc. (“BancShares”) is a financial holding company organized under the laws of Delaware and conducts operations through its banking subsidiary, First-Citizens Bank & Trust Company (“FCB”), which is headquartered in Raleigh, North Carolina. General These consolidated financial statements and notes thereto are presented in accordance with instructions for Form 10-Q and Article 10 of Regulation S-X and, therefore, do not include all information and notes necessary for a complete presentation of financial position, results of operations and cash flow activity required in accordance with accounting principles generally accepted in the United States of America (“GAAP”). In the opinion of management, all normal recurring adjustments necessary for a fair presentation of the consolidated financial position and consolidated results of operations have been made. The unaudited interim consolidated financial statements included in this Form 10-Q should be read in conjunction with the Consolidated Financial Statements and Notes to the Consolidated Financial Statements included in BancShares’ Annual Report on Form 10-K for the year ended December 31, 2019. Reclassifications In certain instances, amounts reported in prior periods’ consolidated financial statements have been reclassified to conform to the current financial statement presentation. Such reclassifications had no effect on previously reported cash flows, shareholders’ equity or net income. Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions which affect the amounts reported. Actual results could differ from those estimates. The estimates BancShares considers significant are the allowance for credit losses, fair value measurements, and income taxes. Issuance of Preferred Stock and Subordinated Debt On March 4, 2020, BancShares completed its public offering of $350 million aggregate principal amount of its 3.375% Fixed-to-Floating Rate Subordinated Notes due 2030 and redeemable at the option of BancShares starting in 2025. On March 12, 2020, BancShares issued and sold an aggregate of 13,800,000 depositary shares, each representing a 1/40th interest in a share of 5.375% Non-Cumulative Perpetual Preferred Stock, Series A, par value $0.01 per share, with a liquidation preference of $25 per Depositary Share (equivalent to $1,000 per share of Series A Preferred Stock) for a total of $345 million. The capital raise provides liquidity for general corporate purposes, which may include, but is not limited to, providing capital to support our growth organically or through strategic acquisitions, financing investments and capital expenditures, for funding investments in First Citizens Bank as regulatory capital, and redeeming or repurchasing our common stock. Share Repurchases During the second quarter of 2020, BancShares repurchased 346,000 shares of Class A common stock for $127.0 million at an average cost per share of $366.98. During the second quarter of 2019, BancShares purchased a total of 205,500 shares of Class A common stock for $89.8 million at an average cost per share of $436.81. During the six months ended June 30, 2020, BancShares repurchased 695,390 shares of Class A common stock for $286.7 million at an average cost per share of $412.23. During the six months ended June 30, 2019, BancShares repurchased a total of 448,500 shares of Class A common stock for $190.5 million at an average cost per share of $424.77. All Class A common stock repurchases were consummated under previously approved authorizations. The share repurchases during 2020 included 45,000 shares of Class A common stock repurchased from Ella Ann Holding, as trustee of her revocable trust. Pursuant to the existing share repurchase authorization and BancShares’ related person transaction policy, the Board of Director’s (the “Board”) independent Audit Committee reviewed and approved the repurchase of up to 250,000 shares held by Mrs. Holding on or before April 30, 2020. Subsequent to quarter-end through July 31, 2020, BancShares repurchased an additional 117,700 shares of Class A common stock for $47.1 million at an average cost per share of $399.77. Upon completion of the current authorization on July 31, 2020, share repurchase activity has been suspended and will be reevaluated in subsequent periods. Small Business Administration Paycheck Protection Program The Small Business Administration Paycheck Protection Program (“SBA-PPP”) is one of the centerpieces of the Coronavirus Aid Relief and Economic Security Act (the “CARES Act”), which was passed on March 27, 2020 in response to the outbreak of coronavirus (“COVID-19”) and was supplemented with subsequent legislation. Overseen by the United States (“U.S.”) Treasury Department, the SBA-PPP offers cash-flow assistance to nonprofit and small business employers through guaranteed loans for expenses incurred between February 15, 2020, and August 8, 2020. Borrowers are eligible for forgiveness of principal and accrued interest on SBA-PPP loans to the extent that the proceeds are used to cover eligible payroll costs, interest costs, rent, and utility costs over a period between eight and 24-weeks after the loan is made as long as the borrower retains its employees and their compensation levels. The CARES Act authorized the SBA to temporarily guarantee these loans. Due to the unique nature of these provisions, SBA-PPP loans have been disclosed as a separate loan class. Origination fees received by the SBA are capitalized into the carrying amount of the loans. The deferred fee income, net of origination costs, is recognized over the life of the loan as an adjustment to yield using the effective interest method. Loans outstanding as of June 30, 2020 totaled $3.08 billion and generated $19.0 million of interest income during the second quarter of 2020. Recently Adopted Accounting Pronouncements Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2018-13 - Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement This ASU modifies the disclosure requirements on fair value measurements by eliminating the requirements to disclose (1) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy (2) the policy for timing of transfers between levels and (3) the valuation processes for Level 3 fair value measurements. This ASU also added specific disclosure requirements for fair value measurements for public business entities including the requirement to disclose the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. BancShares adopted this ASU during the first quarter of 2020 and have made all applicable updates to the disclosure within the Notes to the Unaudited Consolidated Financial Statements. FASB ASU 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment This ASU eliminates Step 2 from the goodwill impairment test. Under Step 2, an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities) following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, under the amendments in this ASU, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. This ASU eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative test. BancShares adopted this ASU during the first quarter 2020 with no impact to our consolidated financial position or consolidated results of operations as a result of the adoption. FASB ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments This ASU (and all subsequent ASUs on this topic) introduce the current expected credit loss (“CECL”) model, a new credit loss methodology, replacing multiple existing impairment methods in current GAAP, which generally require that a loss be incurred before it is recognized. The amendments in this ASU require loss estimates be determined over the lifetime of the asset and broaden the information that an entity must consider in developing its expected credit losses. The ASU does not specify a method for measuring expected credit losses and allows an entity to apply methods that reasonably reflect its expectations of the credit loss estimate based on the entity's size, complexity and risk profile. In addition, the disclosures of credit quality indicators in relation to the amortized cost of financing receivables, a current disclosure requirement, are further disaggregated by year of origination. BancShares adopted this ASU (and all subsequent ASUs on this topic) as of January 1, 2020 using the modified retrospective approach for all loans, leases, debt securities designated as held to maturity, and unfunded loan commitments. BancShares adopted the ASU using the prospective approach for debt securities available for sale and purchased credit deteriorated (“PCD”) loans previously accounted for under Accounting Standard Codification (“ASC”) ASC 310-30. Results for reporting periods beginning after January 1, 2020 are presented under ASC 326, while prior period amounts continue to be reported in accordance with previously applicable GAAP. BancShares made changes to loan classifications and segmentation in order to align with ASC 326 requirements and facilitate CECL modeling. Using this updated segmentation, BancShares developed new loan level models to estimate the allowance for credit losses (“ACL”) and facilitate revised disclosures. The information presented below represents changes from Note A, Accounting Policies and Basis of Presentation, included in BancShares’ Annual Report on Form 10-K for the year ended December 31, 2019, as well as information on the impact of adoption. Accounting Policy - Debt Securities BancShares classifies debt securities as held to maturity (“HTM”) or available for sale (“AFS”). Debt securities are classified as HTM when BancShares has the intent and ability to hold the securities to maturity and are reported at amortized cost. Other debt securities are classified as AFS and reported at estimated fair value, with unrealized gains and losses, net of income taxes, reported in Accumulated Other Comprehensive Income (“AOCI”). Amortization of premiums and accretion of discounts for debt securities are included in interest income. Realized gains and losses from the sale of debt securities are determined by specific identification on a trade date basis and are included in noninterest income. BancShares performs pre-purchase due diligence and evaluates the credit risk of AFS and HTM securities purchased directly into our portfolio or via acquisition. If securities have evidence of more than insignificant credit deterioration since issuance, they are designated as PCD. PCD securities are recorded at fair value at the date of acquisition which includes an associated allowance that is added to the purchase price or fair value to arrive at the Day 1 amortized cost basis. The difference between the purchase price and the Day 1 amortized cost is amortized or accreted to interest income over the contractual life of the securities using the effective interest method. For AFS securities, management performs a quarterly analysis of the investment portfolio to evaluate securities currently in an unrealized loss position for potential credit-related impairment. If BancShares intends to sell a security, or does not have the intent and ability to hold a security before recovering the amortized cost, the entirety of the unrealized loss is immediately recorded in earnings. For the remaining securities, an analysis is performed to determine if any portion of the unrealized loss recorded relates to credit impairment. If credit related impairment exists, the amount is recorded through the ACL and related provision. This review includes indicators such as changes in credit rating, delinquency, bankruptcy or other significant news event impacting the issuer. BancShares’ portfolio of HTM debt securities is made up of mortgage-backed securities issued by government agencies and government sponsored entities. Given the historically strong credit rating of the U.S. Treasury and the long history of no credit losses on debt securities issued by government agencies and government sponsored entities, we determined zero expected credit losses on the HTM portfolio. Accounting Policy - Loans and Leases BancShares’ accounting methods for loans and leases depends on whether they are originated or purchased, and if purchased, whether or not the loans reflect more than insignificant credit deterioration since origination as of the date of acquisition. Non-Purchased Credit Deteriorated (“Non-PCD”) Loans Non-PCD loans consist of loans originated by BancShares and loans purchased from other institutions that do not reflect more than insignificant credit deterioration at acquisition. Originated loans for which management has the intent and ability to hold for the foreseeable future are classified as held for investment and carried at the principal amount outstanding net of any unearned income, charge-offs and unamortized fees and costs. Nonrefundable fees collected and certain direct costs incurred related to loan originations are deferred and recorded as an adjustment to loans outstanding. The net amount of the nonrefundable fees and costs is amortized to interest income over the contractual lives using methods that approximate a constant yield. Purchased loans which do not reflect more than insignificant credit deterioration at acquisition are classified as non-PCD loans. These loans are recorded at fair value at the date of acquisition and an initial allowance is recorded on these assets as provision expense at the date of acquisition. The difference between the fair value and the unpaid principal balance at the acquisition date is amortized or accreted to interest income over the contractual life of the loan using the effective interest method. Purchased Credit Deteriorated Loans Purchased loans which reflect a more than insignificant credit deterioration since origination as of the date of acquisition are classified as PCD and are recorded at acquisition date amortized cost, which is the purchase price or fair value in a business combination, plus our initial estimate of expected credit losses. The difference between the unpaid principal balance and the acquisition date amortized cost is amortized or accreted to interest income over the contractual life of the loan using the effective interest method. The performance of all loans within the BancShares portfolio is subject to a number of external risks, including but not limited to changes in the overall health of the economy, declines in real estate or other collateral values, changes in the demand for products and services and personal events, such as death, disability or change in marital status. BancShares evaluates and reports its non-PCD and PCD loan portfolios separately, and each non-PCD portfolio is further divided into commercial and consumer segments based on the type of borrower, purpose, collateral and/or our underlying credit management processes. Additionally, non-PCD commercial and consumer loans are assigned to loan classes, which further disaggregate the loan portfolio. PCD loans are reported as a single loan segment and class. Upon adoption of ASC 326, owner occupied and non-owner occupied commercial real estate were segregated into separate classes within the commercial segment. Similarly, consumer auto was segregated into its own class within the consumer segment. These enhancements were made to capture the unique credit characteristics used in our CECL models. Information for reporting periods beginning after January 1, 2020 are presented in accordance with ASC 326 and reflect changes to the respective classes, while prior period amounts continue to be reported in accordance with previously applicable GAAP and have not been reclassified to conform to the current financial statement presentation. The following represent our classes of loans as of January 1, 2020 upon adoption of ASC 326 (with the exception of SBA-PPP, which was added during second quarter 2020): Commercial loans and leases Construction and land development - Construction and land development consists of loans to finance land for development of commercial or residential real property and construction of multifamily apartments or other commercial properties. These loans are highly dependent on the supply and demand for commercial real estate as well as the demand for newly constructed residential homes and lots acquired for development. Deterioration in demand could result in decreased collateral values, which could make repayments of outstanding loans difficult for customers. Owner occupied commercial mortgage - Owner occupied commercial mortgages consists of loans to purchase or re-finance owner occupied nonresidential properties. This includes office buildings, other commercial facilities, and farmland. Commercial mortgages secured by owner occupied properties are primarily dependent on the ability of borrowers to achieve business results consistent with those projected at loan origination. While these loans and leases are collateralized by real property in an effort to mitigate risk, it is possible the liquidation of collateral will not fully satisfy the obligation. Non-owner occupied commercial mortgage - Non-owner occupied commercial mortgage consists of loans to purchase or refinance investment nonresidential properties. This includes office buildings and other facilities rented or leased to unrelated parties, as well as farmland and multifamily properties. The primary risk associated with income producing commercial mortgage loans is the ability of the income-producing property that collateralizes the loan to produce adequate cash flow to service the debt. While these loans and leases are collateralized by real property in an effort to mitigate risk, it is possible the liquidation of collateral will not fully satisfy the obligation. Commercial and industrial and leases - Commercial and industrial loans consist of loans or lines of credit to finance accounts receivable, inventory or other general business needs, business credit cards, and lease financing agreements for equipment, vehicles, or other assets. The primary risk associated with commercial and industrial and lease financing loans is the ability of borrowers to achieve business results consistent with those projected at origination. Failure to achieve these projections presents risk the borrower will be unable to service the debt consistent with the contractual terms of the loan or lease. SBA-PPP - These loans were originated as part of the SBA-PPP to finance payroll and other costs for nonprofit and small businesses impacted by the COVID-19 pandemic. These loans are guaranteed by the SBA and borrowers have the ability to qualify for loan forgiveness through the U.S. Treasury. Consumer loans Residential mortgage - Residential mortgage consists of loans to purchase or refinance the borrower’s primary dwelling, second residence or vacation home and are often secured by 1-4 family residential property. Significant and rapid declines in real estate values can result in borrowers having debt levels in excess of the current market value of the collateral. Revolving mortgage - Revolving mortgage consists of home equity lines of credit and other lines of credit secured by first or second liens on the borrower’s primary residence. These loans are secured by both senior and junior liens on the residential real estate and are particularly susceptible to declining collateral values. This risk is elevated for loans secured by junior lines as a substantial decline in value could render a the junior lien position effectively unsecured. Construction and land development - Construction and land development consists of loans to construct a borrower’s primary or secondary residence or vacant land upon which the owner intends to construct a dwelling at a future date. These loans are typically secured by undeveloped or partially developed land in anticipation of completing construction of a 1-4 family residential property. There is risk these construction and development projects can experience delays and cost overruns exceeding the borrower’s financial ability to complete the project. Such cost overruns can result in foreclosure of partially completed and unmarketable collateral. Consumer auto loans - Consumer auto loans consist of installment loans to finance purchases of vehicles. These loans include direct auto loans originated in bank branches, as well indirect auto loans originated through agreements with auto dealerships. The value of the underlying collateral within this class is at risk of potential rapid depreciation which could result in unpaid balances in excess of the collateral. Other consumer - Other consumer loans consist of loans to finance unsecured home improvements, student loans and revolving lines of credit that can be secured or unsecured, including personal credit cards. The value of the underlying collateral within this class is at risk of potential rapid depreciation which could result in unpaid balances in excess of the collateral. Accounting Policy - Nonperforming Assets and Troubled Debt Restructurings Nonperforming Assets (“NPA”) NPAs include nonaccrual loans, past due securities and foreclosed property. Foreclosed property consists of real estate and other assets acquired as a result of loan defaults and is discussed below. All loans are classified as past due when the payment of principal and interest based upon contractual terms is greater than 30 days delinquent. Loans are generally placed on nonaccrual when principal or interest becomes 90 days past due or when it is probable the principal or interest is not fully collectible. When loans are placed on nonaccrual, all previously uncollected accrued interest is reversed from interest income and the ongoing accrual of interest is discontinued. All payments received thereafter are applied as a reduction of the remaining principal balance as long as doubt exists as to the ultimate collection of the principal. Loans and leases are generally removed from nonaccrual status when they become current for a sustained period of time and there is no longer concern as to the collectability of principal and interest. Securities are also classified as past due when the payment of principal and interest based upon contractual terms is greater than 30 days delinquent. Missed interest payments on securities are rare. We review all securities with delinquent interest and immediately charge off any accrued interest determined to be uncollectible. Troubled Debt Restructurings (“TDR”) A loan is considered a TDR when both of the following occur: (1) a modification to a borrower’s debt agreement is made and (2) a concession is granted for economic or legal reasons related to a borrower’s financial difficulties that otherwise would not be granted. TDR concessions could include short-term deferrals of interest, modifications of payment terms, or (in certain limited instances) forgiveness of principal or interest. Loans restructured as a TDR are treated and reported as such for the remaining life of the loan. TDR loans can be nonaccrual or accrual, depending on the individual facts and circumstances of the borrower. In circumstances where a portion of the loan balance is charged-off, the remaining balance is typically classified as nonaccrual. Accounting Policy - Allowance for Credit Losses (“ACL”) Loans Loans within the various reporting classes are segregated into pools with similar risk characteristics and models are built to estimate the ACL. These loan level ACL models estimate the probability of default and loss given default for individual loans within the risk pool based on historical loss experience, borrower characteristics, collateral type, forecasts of relevant economic conditions, expected future recoveries and other factors. Pools for estimating the ACL are aggregated into loan classes, as described above, which roll up into commercial and consumer loan segments. Non-PCD and PCD loans are modeled together within the loan level models using acquired and PCD indicator variables to provide differentiation of individual loan risk. BancShares uses a two year reasonable and supportable forecast period which incorporates economic forecasts at the time of evaluation. For most pools, BancShares uses a 12-month straight-line reversion period to historical averages for model inputs; however for the consumer other, consumer card and commercial card pools, immediate reversion to historical net loss rates is utilized. The ACL for SBA-PPP loans originated during the second quarter of 2020 were separately evaluated given the explicit government guarantee. This analysis, which incorporated historical experience with similar SBA guarantees and underwriting, concluded the likelihood of loss was remote and therefore these loans were assigned a zero expected credit loss in the ACL. The ACL represents management’s best estimate of credit losses expected over the life of the loan, adjusted for expected contractual payments and the impact of prepayment expectations. Prepayment assumptions were developed through a review of BancShares’ historical prepayment activity and began with a review of prepayment assumptions utilized in other modeling activities. Estimates for loan losses are determined by analyzing quantitative and qualitative components present as of the evaluation date. Adjustments to the ACL are recorded with a corresponding entry to provision for credit losses. Loan balances considered uncollectible are charged-off against the ACL. Recoveries of amounts previously charged-off are credited to the ACL. A primary component of determining the ACL on loans is the actual net loss history of the various loan pools. For commercial pools, key factors utilized in the models include delinquency trends as well as macroeconomic variables such as unemployment and commercial real estate price index. For consumer pools, key factors include delinquency trends and the borrower’s original credit score, as well as other macroeconomic variables such as unemployment, gross domestic product, home price index, and commercial real estate index. As the models project losses over the life of the loans, prepayment assumptions also serve as significant inputs. Model outputs may be adjusted through a qualitative assessment to reflect economic conditions and trends not captured within the models including credit quality, concentrations, and significant policy and underwriting changes. Within our ACL model, TDRs meet the definition of default and are given a 100% probability of default rating. TDRs are not individually evaluated unless determined to be collateral-dependent. Therefore, loss given default is calculated based on the individual risk characteristics of the loan as defined in the model. When loans do not share risk characteristics similar to others in the pool, the ACL is evaluated on an individual basis. Given that BancShares' CECL models are loan level models, the population of loans evaluated individually is minimal and consists primarily of loans greater than $500 thousand and determined to be collateral-dependent. BancShares elected the practical expedient allowed under ASC 326 to assess the collectability of these loans, where repayment is expected to be provided substantially through operation or sale of collateral, based on the fair value of the underlying collateral. The fair value of the collateral is estimated using appraised and market values (appropriately adjusted for an assessment of the sales and marketing costs when applicable). A specific allowance is established, or partial charge-off is recorded, for the difference between the excess amortized cost of loan and the collateral’s estimated fair value. Accrued Interest Receivable BancShares has elected not to measure an ACL for accrued interest receivable and has excluded it from the amortized cost basis of loans and held to maturity debt securities as our accounting policies and credit monitoring provide that uncollectible accrued interest is reversed or written off against interest income in a timely manner. Unfunded Commitments A reserve for unfunded commitments is established for off-balance sheet exposures such as unfunded balances for existing lines of credit, commitments to extend future credit, as well a both standby and commercial letters of credit when there is a contractual obligation to extend credit and when this extension of credit is not unconditionally cancellable (i.e. commitment cannot canceled at any time). These unfunded commitments are assessed to determine both the probability of funding as well the expectation of future losses. The expected funding balance is used in the probability of default and loss given default models to determine the reserve. The reserve for unfunded commitments was $13.7 million at June 30, 2020, and is recorded within other liabilities with changes recorded through other expense. Adoption Impact Upon adoption, BancShares recorded a net decrease of $37.9 million in the ACL which included a reduction of $56.9 million in the ACL on non-PCD loans, offset by an increase of $19.0 million in the ACL on PCD loans. The $56.9 million reduction in the ACL on non-PCD loans, as well as an $8.9 million increase in the reserve for unfunded commitments, net of deferred taxes, resulted in an increase in retained earnings of $36.9 million. The $19.0 million increase in the ACL on PCD loans was a reclassification of the PCD credit discount and resulted in a gross up of loan balances by this same amount and did not have any effect on retained earnings. Impact to total capital and capital ratios was not significant and we did not elect the capital phase-in option allowable for regulatory reporting purposes. There was no ACL recorded on debt securities held to maturity at adoption. The largest changes in the ACL, affecting beginning retained earnings as a result of the adoption, were decreases in the ACL on commercial loan segments as these portfolios have exhibited strong historical credit performance and have relatively short average lives. The reduction in ACL on these segments was partially offset by increases in ACL on our consumer loan segments primarily due to their longer average lives. The increase in the reserve for unfunded commitments was primarily due to increases in the scope of off-balance sheet exposures considered in this estimate due to the provisions in ASU 2016-13. BancShares adopted this ASU using the prospective transition approach for PCD loans previously accounted for under ASC 310-30. In accordance with the standard, we did not assess whether purchased credit impaired (“PCI”) loans met the criteria of PCD as of the date of adoption and all loans previously classified as PCI were updated to the PCD classification. Pools utilized for PCI accounting under ASC 310-30 were dissolved upon adoption. Loans from performing PCI pools, not previously considered nonaccrual of $47.0 million, were reclassified into nonaccrual status as a result of adoption. PCD loans were assessed using the loan level probability of default and loss given default models, as well as utilizing prior specific loan reviews to inform the initial PCD loan ACL. The ACL for PCD loans increased as a result of adoption and the amortized cost basis of these loans was adjusted to reflect the transfer of this amount from credit discount to ACL. The remaining noncredit discount will be accreted into interest income at the effective interest rate as of January 1, 2020. At the date of adoption, no securities were determined to be PCD. BancShares also adopted this ASU under the prospective transition approach for debt securities available for sale. No previously recorded other than temporary impairment was reported on the portfolio of debt securities. Recently Issued Accounting Pronouncements FASB ASU 2018-14 - Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans This ASU modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans by eliminating the requirement to disclose the amounts in accumulated other comprehensive income expected to be recognized as components of net periodic benefit cost over the next fiscal year and adding a requirement to disclose an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. The amendments in this ASU are effective for public entities for fiscal years ending after December 15, 2020. Early adoption is permitted for all entities. BancShares will adopt all applicable amendments and update the disclosures as appropriate during the fourth quarter of 2020.

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.

These consolidated financial statements and notes thereto are presented in accordance with instructions for Form 10-Q and Article 10 of Regulation S-X and, therefore, do not include all information and notes necessary for a complete presentation of financial position, results of operations and cash flow activity required in accordance with accounting principles generally accepted in the United States of America (“GAAP”). In the opinion of management, all normal recurring adjustments necessary for a fair presentation of the consolidated financial position and consolidated results of operations have been made. The unaudited interim consolidated financial statements included in this Form 10-Q should be read in conjunction with the Consolidated Financial Statements and Notes to the Consolidated Financial Statements included in BancShares’ Annual Report on Form 10-K for the year ended December 31, 2019.

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

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions which affect the amounts reported. Actual results could differ from those estimates. The estimates BancShares considers significant are the allowance for credit losses, fair value measurements, and income taxes.

On March 4, 2020, BancShares completed its public offering of $350 million aggregate principal amount of its 3.375% Fixed-to-Floating Rate Subordinated Notes due 2030 and redeemable at the option of BancShares starting in 2025. On March 12, 2020, BancShares issued and sold an aggregate of 13,800,000 depositary shares, each representing a 1/40th interest in a share of 5.375% Non-Cumulative Perpetual Preferred Stock, Series A, par value $0.01 per share, with a liquidation preference of $25 per Depositary Share (equivalent to $1,000 per share of Series A Preferred Stock) for a total of $345 million. The capital raise provides liquidity for general corporate purposes, which may include, but is not limited to, providing capital to support our growth organically or through strategic acquisitions, financing investments and capital expenditures, for funding investments in First Citizens Bank as regulatory capital, and redeeming or repurchasing our common stock.

During the second quarter of 2020, BancShares repurchased 346,000 shares of Class A common stock for $127.0 million at an average cost per share of $366.98. During the second quarter of 2019, BancShares purchased a total of 205,500 shares of Class A common stock for $89.8 million at an average cost per share of $436.81. During the six months ended June 30, 2020, BancShares repurchased 695,390 shares of Class A common stock for $286.7 million at an average cost per share of $412.23. During the six months ended June 30, 2019, BancShares repurchased a total of 448,500 shares of Class A common stock for $190.5 million at an average cost per share of $424.77. All Class A common stock repurchases were consummated under previously approved authorizations.

The share repurchases during 2020 included 45,000 shares of Class A common stock repurchased from Ella Ann Holding, as trustee of her revocable trust. Pursuant to the existing share repurchase authorization and BancShares’ related person transaction policy, the Board of Director’s (the “Board”) independent Audit Committee reviewed and approved the repurchase of up to 250,000 shares held by Mrs. Holding on or before April 30, 2020.

Subsequent to quarter-end through July 31, 2020, BancShares repurchased an additional 117,700 shares of Class A common stock for $47.1 million at an average cost per share of $399.77. Upon completion of the current authorization on July 31, 2020, share repurchase activity has been suspended and will be reevaluated in subsequent periods.

The Small Business Administration Paycheck Protection Program (“SBA-PPP”) is one of the centerpieces of the Coronavirus Aid Relief and Economic Security Act (the “CARES Act”), which was passed on March 27, 2020 in response to the outbreak of coronavirus (“COVID-19”) and was supplemented with subsequent legislation. Overseen by the United States (“U.S.”) Treasury Department, the SBA-PPP offers cash-flow assistance to nonprofit and small business employers through guaranteed loans for expenses incurred between February 15, 2020, and August 8, 2020. Borrowers are eligible for forgiveness of principal and accrued interest on SBA-PPP loans to the extent that the proceeds are used to cover eligible payroll costs, interest costs, rent, and utility costs over a period between eight and 24-weeks after the loan is made as long as the borrower retains its employees and their compensation levels. The CARES Act authorized the SBA to temporarily guarantee these loans.

Due to the unique nature of these provisions, SBA-PPP loans have been disclosed as a separate loan class. Origination fees received by the SBA are capitalized into the carrying amount of the loans. The deferred fee income, net of origination costs, is recognized over the life of the loan as an adjustment to yield using the effective interest method. Loans outstanding as of June 30, 2020 totaled $3.08 billion and generated $19.0 million of interest income during the second quarter of 2020.

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

This ASU eliminates Step 2 from the goodwill impairment test. Under Step 2, an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities) following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, under the amendments in this ASU, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. This ASU eliminates the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative test.

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

BancShares adopted this ASU (and all subsequent ASUs on this topic) as of January 1, 2020 using the modified retrospective approach for all loans, leases, debt securities designated as held to maturity, and unfunded loan commitments. BancShares adopted the ASU using the prospective approach for debt securities available for sale and purchased credit deteriorated (“PCD”) loans previously accounted for under Accounting Standard Codification (“ASC”) ASC 310-30. Results for reporting periods beginning after January 1, 2020 are presented under ASC 326, while prior period amounts continue to be reported in accordance with previously applicable GAAP. BancShares made changes to loan classifications and segmentation in order to align with ASC 326 requirements and facilitate CECL modeling. Using this updated segmentation, BancShares developed new loan level models to estimate the allowance for credit losses (“ACL”) and facilitate revised disclosures.

BancShares classifies debt securities as held to maturity (“HTM”) or available for sale (“AFS”). Debt securities are classified as HTM when BancShares has the intent and ability to hold the securities to maturity and are reported at amortized cost. Other debt securities are classified as AFS and reported at estimated fair value, with unrealized gains and losses, net of income taxes, reported in Accumulated Other Comprehensive Income (“AOCI”). Amortization of premiums and accretion of discounts for debt securities are included in interest income. Realized gains and losses from the sale of debt securities are determined by specific identification on a trade date basis and are included in noninterest income.

BancShares performs pre-purchase due diligence and evaluates the credit risk of AFS and HTM securities purchased directly into our portfolio or via acquisition. If securities have evidence of more than insignificant credit deterioration since issuance, they are designated as PCD. PCD securities are recorded at fair value at the date of acquisition which includes an associated allowance that is added to the purchase price or fair value to arrive at the Day 1 amortized cost basis. The difference between the purchase price and the Day 1 amortized cost is amortized or accreted to interest income over the contractual life of the securities using the effective interest method.

For AFS securities, management performs a quarterly analysis of the investment portfolio to evaluate securities currently in an unrealized loss position for potential credit-related impairment. If BancShares intends to sell a security, or does not have the intent and ability to hold a security before recovering the amortized cost, the entirety of the unrealized loss is immediately recorded in earnings. For the remaining securities, an analysis is performed to determine if any portion of the unrealized loss recorded relates to credit impairment. If credit related impairment exists, the amount is recorded through the ACL and related provision. This review includes indicators such as changes in credit rating, delinquency, bankruptcy or other significant news event impacting the issuer.

BancShares’ portfolio of HTM debt securities is made up of mortgage-backed securities issued by government agencies and government sponsored entities. Given the historically strong credit rating of the U.S. Treasury and the long history of no credit losses on debt securities issued by government agencies and government sponsored entities, we determined zero expected credit losses on the HTM portfolio.

Originated loans for which management has the intent and ability to hold for the foreseeable future are classified as held for investment and carried at the principal amount outstanding net of any unearned income, charge-offs and unamortized fees and costs. Nonrefundable fees collected and certain direct costs incurred related to loan originations are deferred and recorded as an adjustment to loans outstanding. The net amount of the nonrefundable fees and costs is amortized to interest income over the contractual lives using methods that approximate a constant yield.

Purchased loans which do not reflect more than insignificant credit deterioration at acquisition are classified as non-PCD loans. These loans are recorded at fair value at the date of acquisition and an initial allowance is recorded on these assets as provision expense at the date of acquisition. The difference between the fair value and the unpaid principal balance at the acquisition date is amortized or accreted to interest income over the contractual life of the loan using the effective interest method.

Purchased loans which reflect a more than insignificant credit deterioration since origination as of the date of acquisition are classified as PCD and are recorded at acquisition date amortized cost, which is the purchase price or fair value in a business combination, plus our initial estimate of expected credit losses. The difference between the unpaid principal balance and the acquisition date amortized cost is amortized or accreted to interest income over the contractual life of the loan using the effective interest method.

The performance of all loans within the BancShares portfolio is subject to a number of external risks, including but not limited to changes in the overall health of the economy, declines in real estate or other collateral values, changes in the demand for products and services and personal events, such as death, disability or change in marital status. BancShares evaluates and reports its non-PCD and PCD loan portfolios separately, and each non-PCD portfolio is further divided into commercial and consumer segments based on the type of borrower, purpose, collateral and/or our underlying credit management processes. Additionally, non-PCD commercial and consumer loans are assigned to loan classes, which further disaggregate the loan portfolio. PCD loans are reported as a single loan segment and class.

Upon adoption of ASC 326, owner occupied and non-owner occupied commercial real estate were segregated into separate classes within the commercial segment. Similarly, consumer auto was segregated into its own class within the consumer segment. These enhancements were made to capture the unique credit characteristics used in our CECL models. Information for reporting periods beginning after January 1, 2020 are presented in accordance with ASC 326 and reflect changes to the respective classes, while prior period amounts continue to be reported in accordance with previously applicable GAAP and have not been reclassified to conform to the current financial statement presentation.

Construction and land development - Construction and land development consists of loans to finance land for development of commercial or residential real property and construction of multifamily apartments or other commercial properties. These loans are highly dependent on the supply and demand for commercial real estate as well as the demand for newly constructed residential homes and lots acquired for development. Deterioration in demand could result in decreased collateral values, which could make repayments of outstanding loans difficult for customers.

Owner occupied commercial mortgage - Owner occupied commercial mortgages consists of loans to purchase or re-finance owner occupied nonresidential properties. This includes office buildings, other commercial facilities, and farmland. Commercial mortgages secured by owner occupied properties are primarily dependent on the ability of borrowers to achieve business results consistent with those projected at loan origination. While these loans and leases are collateralized by real property in an effort to mitigate risk, it is possible the liquidation of collateral will not fully satisfy the obligation.

Non-owner occupied commercial mortgage - Non-owner occupied commercial mortgage consists of loans to purchase or refinance investment nonresidential properties. This includes office buildings and other facilities rented or leased to unrelated parties, as well as farmland and multifamily properties. The primary risk associated with income producing commercial mortgage loans is the ability of the income-producing property that collateralizes the loan to produce adequate cash flow to service the debt. While these loans and leases are collateralized by real property in an effort to mitigate risk, it is possible the liquidation of collateral will not fully satisfy the obligation.

Commercial and industrial and leases - Commercial and industrial loans consist of loans or lines of credit to finance accounts receivable, inventory or other general business needs, business credit cards, and lease financing agreements for equipment, vehicles, or other assets. The primary risk associated with commercial and industrial and lease financing loans is the ability of borrowers to achieve business results consistent with those projected at origination. Failure to achieve these projections presents risk the borrower will be unable to service the debt consistent with the contractual terms of the loan or lease.

SBA-PPP - These loans were originated as part of the SBA-PPP to finance payroll and other costs for nonprofit and small businesses impacted by the COVID-19 pandemic. These loans are guaranteed by the SBA and borrowers have the ability to qualify for loan forgiveness through the U.S. Treasury.

Residential mortgage - Residential mortgage consists of loans to purchase or refinance the borrower’s primary dwelling, second residence or vacation home and are often secured by 1-4 family residential property. Significant and rapid declines in real estate values can result in borrowers having debt levels in excess of the current market value of the collateral.

Revolving mortgage - Revolving mortgage consists of home equity lines of credit and other lines of credit secured by first or second liens on the borrower’s primary residence. These loans are secured by both senior and junior liens on the residential real estate and are particularly susceptible to declining collateral values. This risk is elevated for loans secured by junior lines as a substantial decline in value could render a the junior lien position effectively unsecured.

Construction and land development - Construction and land development consists of loans to construct a borrower’s primary or secondary residence or vacant land upon which the owner intends to construct a dwelling at a future date. These loans are typically secured by undeveloped or partially developed land in anticipation of completing construction of a 1-4 family residential property. There is risk these construction and development projects can experience delays and cost overruns exceeding the borrower’s financial ability to complete the project. Such cost overruns can result in foreclosure of partially completed and unmarketable collateral.

Consumer auto loans - Consumer auto loans consist of installment loans to finance purchases of vehicles. These loans include direct auto loans originated in bank branches, as well indirect auto loans originated through agreements with auto dealerships. The value of the underlying collateral within this class is at risk of potential rapid depreciation which could result in unpaid balances in excess of the collateral.

Other consumer - Other consumer loans consist of loans to finance unsecured home improvements, student loans and revolving lines of credit that can be secured or unsecured, including personal credit cards. The value of the underlying collateral within this class is at risk of potential rapid depreciation which could result in unpaid balances in excess of the collateral.

All loans are classified as past due when the payment of principal and interest based upon contractual terms is greater than 30 days delinquent. Loans are generally placed on nonaccrual when principal or interest becomes 90 days past due or when it is probable the principal or interest is not fully collectible. When loans are placed on nonaccrual, all previously uncollected accrued interest is reversed from interest income and the ongoing accrual of interest is discontinued. All payments received thereafter are applied as a reduction of the remaining principal balance as long as doubt exists as to the ultimate collection of the principal. Loans and leases are generally removed from nonaccrual status when they become current for a sustained period of time and there is no longer concern as to the collectability of principal and interest.

Securities are also classified as past due when the payment of principal and interest based upon contractual terms is greater than 30 days delinquent. Missed interest payments on securities are rare. We review all securities with delinquent interest and immediately charge off any accrued interest determined to be uncollectible.

A loan is considered a TDR when both of the following occur: (1) a modification to a borrower’s debt agreement is made and (2) a concession is granted for economic or legal reasons related to a borrower’s financial difficulties that otherwise would not be granted. TDR concessions could include short-term deferrals of interest, modifications of payment terms, or (in certain limited instances) forgiveness of principal or interest. Loans restructured as a TDR are treated and reported as such for the remaining life of the loan. TDR loans can be nonaccrual or accrual, depending on the individual facts and circumstances of the borrower. In circumstances where a portion of the loan balance is charged-off, the remaining balance is typically classified as nonaccrual.

Loans within the various reporting classes are segregated into pools with similar risk characteristics and models are built to estimate the ACL. These loan level ACL models estimate the probability of default and loss given default for individual loans within the risk pool based on historical loss experience, borrower characteristics, collateral type, forecasts of relevant economic conditions, expected future recoveries and other factors. Pools for estimating the ACL are aggregated into loan classes, as described above, which roll up into commercial and consumer loan segments. Non-PCD and PCD loans are modeled together within the loan level models using acquired and PCD indicator variables to provide differentiation of individual loan risk. BancShares uses a two year reasonable and supportable forecast period which incorporates economic forecasts at the time of evaluation. For most pools, BancShares uses a 12-month straight-line reversion period to historical averages for model inputs; however for the consumer other, consumer card and commercial card pools, immediate reversion to historical net loss rates is utilized.

The ACL for SBA-PPP loans originated during the second quarter of 2020 were separately evaluated given the explicit government guarantee. This analysis, which incorporated historical experience with similar SBA guarantees and underwriting, concluded the likelihood of loss was remote and therefore these loans were assigned a zero expected credit loss in the ACL.

The ACL represents management’s best estimate of credit losses expected over the life of the loan, adjusted for expected contractual payments and the impact of prepayment expectations. Prepayment assumptions were developed through a review of BancShares’ historical prepayment activity and began with a review of prepayment assumptions utilized in other modeling activities. Estimates for loan losses are determined by analyzing quantitative and qualitative components present as of the evaluation date. Adjustments to the ACL are recorded with a corresponding entry to provision for credit losses. Loan balances considered uncollectible are charged-off against the ACL. Recoveries of amounts previously charged-off are credited to the ACL.

A primary component of determining the ACL on loans is the actual net loss history of the various loan pools. For commercial pools, key factors utilized in the models include delinquency trends as well as macroeconomic variables such as unemployment and commercial real estate price index. For consumer pools, key factors include delinquency trends and the borrower’s original credit score, as well as other macroeconomic variables such as unemployment, gross domestic product, home price index, and commercial real estate index. As the models project losses over the life of the loans, prepayment assumptions also serve as significant inputs. Model outputs may be adjusted through a qualitative assessment to reflect economic conditions and trends not captured within the models including credit quality, concentrations, and significant policy and underwriting changes.

Within our ACL model, TDRs meet the definition of default and are given a 100% probability of default rating. TDRs are not individually evaluated unless determined to be collateral-dependent. Therefore, loss given default is calculated based on the individual risk characteristics of the loan as defined in the model.

When loans do not share risk characteristics similar to others in the pool, the ACL is evaluated on an individual basis. Given that BancShares' CECL models are loan level models, the population of loans evaluated individually is minimal and consists primarily of loans greater than $500 thousand and determined to be collateral-dependent. BancShares elected the practical expedient allowed under ASC 326 to assess the collectability of these loans, where repayment is expected to be provided substantially through operation or sale of collateral, based on the fair value of the underlying collateral. The fair value of the collateral is estimated using appraised and market values (appropriately adjusted for an assessment of the sales and marketing costs when applicable). A specific allowance is established, or partial charge-off is recorded, for the difference between the excess amortized cost of loan and the collateral’s estimated fair value.

BancShares has elected not to measure an ACL for accrued interest receivable and has excluded it from the amortized cost basis of loans and held to maturity debt securities as our accounting policies and credit monitoring provide that uncollectible accrued interest is reversed or written off against interest income in a timely manner.

A reserve for unfunded commitments is established for off-balance sheet exposures such as unfunded balances for existing lines of credit, commitments to extend future credit, as well a both standby and commercial letters of credit when there is a contractual obligation to extend credit and when this extension of credit is not unconditionally cancellable (i.e. commitment cannot canceled at any time). These unfunded commitments are assessed to determine both the probability of funding as well the expectation of future losses. The expected funding balance is used in the probability of default and loss given default models to determine the reserve. The reserve for unfunded commitments was $13.7 million at June 30, 2020, and is recorded within other liabilities with changes recorded through other expense.

Upon adoption, BancShares recorded a net decrease of $37.9 million in the ACL which included a reduction of $56.9 million in the ACL on non-PCD loans, offset by an increase of $19.0 million in the ACL on PCD loans. The $56.9 million reduction in the ACL on non-PCD loans, as well as an $8.9 million increase in the reserve for unfunded commitments, net of deferred taxes, resulted in an increase in retained earnings of $36.9 million. The $19.0 million increase in the ACL on PCD loans was a reclassification of the PCD credit discount and resulted in a gross up of loan balances by this same amount and did not have any effect on retained earnings. Impact to total capital and capital ratios was not significant and we did not elect the capital phase-in option allowable for regulatory reporting purposes. There was no ACL recorded on debt securities held to maturity at adoption.

The largest changes in the ACL, affecting beginning retained earnings as a result of the adoption, were decreases in the ACL on commercial loan segments as these portfolios have exhibited strong historical credit performance and have relatively short average lives. The reduction in ACL on these segments was partially offset by increases in ACL on our consumer loan segments primarily due to their longer average lives. The increase in the reserve for unfunded commitments was primarily due to increases in the scope of off-balance sheet exposures considered in this estimate due to the provisions in ASU 2016-13.

BancShares adopted this ASU using the prospective transition approach for PCD loans previously accounted for under ASC 310-30. In accordance with the standard, we did not assess whether purchased credit impaired (“PCI”) loans met the criteria of PCD as of the date of adoption and all loans previously classified as PCI were updated to the PCD classification. Pools utilized for PCI accounting under ASC 310-30 were dissolved upon adoption. Loans from performing PCI pools, not previously considered nonaccrual of $47.0 million, were reclassified into nonaccrual status as a result of adoption. PCD loans were assessed using the loan level probability of default and loss given default models, as well as utilizing prior specific loan reviews to inform the initial PCD loan ACL. The ACL for PCD loans increased as a result of adoption and the amortized cost basis of these loans was adjusted to reflect the transfer of this amount from credit discount to ACL. The remaining noncredit discount will be accreted into interest income at the effective interest rate as of January 1, 2020. At the date of adoption, no securities were determined to be PCD.

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

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