Flagstar Bancorp, Inc., is a savings and loan holding company founded in 1993. The Company's business is primarily conducted through its principal subsidiary, Flagstar Bank, FSB (the "Bank"), a federally chartered stock savings bank founded in 1987. We are one of the largest banks headquartered in Michigan. When we refer to "Flagstar", "the Company", "we", "our", or "us," we mean Flagstar Bancorp, Inc. and our consolidated subsidiaries.

The Company is subject to regulation, examination and supervision by the Federal Reserve. The Bank is subject to regulation, examination and supervision by the OCC of the U.S. Department of the Treasury, the CFPB and the FDIC. The Bank is a member of the FHLB of Indianapolis and its deposits are insured by the FDIC through the Deposit Insurance Fund.

Our accounting and financial reporting policies conform to accounting principles generally accepted in the United States. Additionally, where applicable the policies conform to the accounting and reporting guidelines prescribed by regulatory authorities. Certain prior period amounts have been reclassified to conform to the current period presentation. The preparation of the Consolidated Financial Statements, requires Management to make estimates and assumptions that affect reported amounts of assets and liabilities, revenues and expenses and disclosures of contingent assets and liabilities. Actual results could be materially different from these estimates.

On April 26, 2021, it was announced that New York Community Bancorp, Inc. ("NYCB") and Flagstar had entered into a definitive merger agreement (the "Merger Agreement") under which the two companies will combine in an all stock merger. Under the terms of the Merger Agreement, Flagstar shareholders will receive 4.0151 shares of NYCB common stock for each Flagstar share they own. The combined company expects to have over $85 billion in assets and operate nearly 400 traditional branches in nine states and over 80 loan production offices across a 28 state footprint. On August 4, 2021, Flagstar's and NYCB's shareholders each voted in their respective special meetings of shareholders to approve the proposed business combination. The transaction is subject to customary closing conditions, including regulatory approvals.

Cash and cash equivalents include cash on hand, amounts due from correspondent banks and the FRB, and short-term investments that have a maturity at the date of acquisition of three months or less and are readily convertible to cash. Restricted cash includes cash that the Bank pledges as maintenance margin on centrally cleared derivatives and is included in other assets on the Consolidated Statements of Financial Condition.

We measure securities classified as AFS at fair value, with unrealized gains and losses, net of tax, included in other comprehensive income (loss) in stockholders’ equity. We recognize realized gains and losses on AFS securities when securities are sold. The cost of securities sold is based on the specific identification method. Any gains or losses realized upon the sale of a security are reported in other noninterest income in the Consolidated Statements of Operations. The fair value of investment securities is based on observable market prices, when available. If observable market prices are not available, our valuations are based on alternative methods, including: quotes for similar fixed-income securities, matrix pricing, or discounted cash flow methods. Fair values are obtained through an independent third party utilizing a pricing service and are compared to independent pricing sources on a quarterly basis. For further information, see Note 2 - Investment Securities and Note 20 - Fair Value Measurements.

Investment securities HTM are carried at amortized cost and are adjusted for the amortization of premiums and accretion of discounts using the interest method. Transfers of investment securities into the HTM category from the AFS category are accounted for at fair value at the date of transfer. Any related unrealized holding gain (loss), net of tax, that was included in the transfer is retained in other comprehensive income (loss) and is amortized as an adjustment to interest income over the remaining life of the securities.

securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses; therefore, we apply a zero credit loss assumption to this portfolio and did not record any credit allowance for each of the three years ended December 31, 2021.

We evaluate AFS debt securities where the value has declined below amortized cost for impairment. If we intend to sell or believe it is more likely than not that we will be required to sell the debt security, it is written down to fair value through earnings. For AFS debt securities we intend to hold, we evaluate the debt securities for expected credit losses, except for debt securities that are guaranteed by the U.S. Treasury, U.S. government agencies or sovereign entities of high credit quality for which we apply a zero loss assumption and comprised 82 percent of our AFS portfolio at December 31, 2021. For the remaining AFS securities, any decline in fair value that is related to market factors is recognized in OCI and credit losses are recognized as an increase to the ACL through the credit loss provision. For each of the years in the three-year period ended December 31, 2021, we had no unrealized credit losses.

Investment securities transactions are recorded on the trade date for purchases and sales. Interest earned on investment securities, including the amortization of premiums and the accretion of discounts, are determined using the effective interest method over the period of maturity and recorded in interest income in the Consolidated Statements of Operations. Accrued interest receivable on investment securities totaled $4 million at December 31, 2021 and was reported in Other assets on the Consolidated Statements of Financial Condition.

We classify loans as LHFS when we originate or purchase loans that we intend to sell. We have elected the fair value option for the majority of our LHFS. We estimate the fair value of mortgage loans based on quoted market prices for securities backed by similar types of loans, where available, or by discounting estimated cash flows using observable inputs inclusive of interest rates, prepayment speeds and loss assumptions for similar collateral. Changes in fair value are recorded to other noninterest income on the Consolidated Statements of Operations. LHFS that are recorded at lower of cost or fair value may be carried at fair value on a nonrecurring basis when the fair value is less than cost. For further information, see Note 20 - Fair Value Measurements.

We classify loans that we have the intent and ability to hold for the foreseeable future or until maturity as LHFI. Loans held-for-investment are reported at their amortized cost, which includes the outstanding principal balance adjusted for any unamortized premiums, discounts, deferred fees and costs. Accrued interest receivable on loans held-for-for investment totaled $35 million at December 31, 2021 and was reported in Other assets on the Consolidated Statements of Financial Condition. Premiums and discounts on purchased loans and non-refundable loan origination and commitment fees, net of direct costs of originating or acquiring loans, are deferred and recognized over the life of the related loans as an adjustment to the loans’ effective yield, which is included in interest income on loans in the Consolidated Statements of Operations.

Loans originally classified as LHFS, for which we have elected the fair value option, and subsequently transferred to LHFI continue to be measured and reported at fair value on a recurring basis. Changes in fair value are recorded to other noninterest income on the Consolidated Statements of Operations. The fair value of these loans is determined using the same methods described above for LHFS. For further information, see Note 20 - Fair Value Measurements.

Loans are considered to be past due when any payment of principal or interest is 30 days past the scheduled payment date. While it is the goal of Management to collect on loans, we attempt to work out a satisfactory repayment schedule or modification with past due borrowers and will undertake foreclosure proceedings if the delinquency is not satisfactorily resolved. Our practices regarding past due loans are designed to both assist borrowers in meeting their contractual obligations and minimize losses incurred by the bank.

We cease the accrual of interest on all classes of consumer and commercial loans upon the earlier of, becoming 90 days past due, or when doubt exists as to the ultimate collection of principal or interest (classified as nonaccrual or NPLs). When a loan is placed on nonaccrual status, the accrued interest income is reversed against interest income and the loan may only return to accrual status when principal and interest become current and are anticipated to be fully collectible. We do not measure an ACL for accrued interest receivables as accrued interest is written off in a timely manner.

Loans are considered impaired if it is probable that payment of all interest and principal will not be made in accordance with the original contractual terms of the loan agreement or when any portion of principal or interest is 90 days past due. This classification includes both performing and nonperforming modified loans. For further information, see Note 4 - Loans Held-for-Investment.

When a loan is considered impaired, the accrual of interest income is discontinued until the receipt of principal and interest is no longer in doubt. Interest income is recognized on impaired loans using a cost recovery method unless amounts contractually due are not in doubt. Cash received on nonperforming impaired loans is applied entirely against principal until the loan has been collected in full, after which time any additional cash receipts are recognized as interest income.

We may modify certain loans in both our consumer and commercial loan portfolios to retain customers or to maximize collection of the outstanding loan balance. We have programs designed to assist borrowers by extending payment dates or reducing the borrower's contractual payments. All loan modifications are made on a case-by-case basis. Our standards relating to loan modifications consider, among other factors, minimum verified income requirements, cash flow analysis and collateral valuations. TDRs result in those instances in which a borrower demonstrates financial difficulty and for which a concession has been granted, including reductions of interest rates, extensions of amortization periods, principal and/or interest forgiveness and other actions intended to minimize the economic loss and to avoid foreclosure or repossession of collateral. These loans are classified as nonperforming TDRs if the loan was nonperforming prior to the restructuring, or based upon the results of a contemporaneous credit evaluation. Such loans will continue on nonaccrual status until the borrower has established a willingness and ability to make the restructured payments for at least six months, after which they will be classified as performing TDRs and will begin to accrue interest. Performing and nonperforming TDRs remain impaired as interest and principal will not be received in accordance with the original contractual terms of the loan agreement.

Some loan modifications classified as TDRs may not ultimately result in the full collection of principal and interest, as modified, but may give rise to potential incremental losses. We measure impairments using a discounted cash flow method for performing TDRs and measure impairment based on collateral values for collateral-dependent nonperforming TDRs.

Beginning in March 2020, as a response to COVID-19, we offered our consumer borrowers principal and interest payment deferrals, forbearance and/or extensions up to a maximum period of 18 months. We considered these programs in the context of whether or not the short-term modifications of these loans would constitute a TDR. We considered the CARES Act, interagency guidance and related guidance from the FASB, which provided that short-term modifications made on a good faith basis in response to COVID-19 to borrowers who were current prior to any relief are not required to be accounted for as TDRs. As a result, we have determined that loan forbearance, modifications, deferrals and extensions made under these COVID-19 programs are not TDRs.

We determine the estimate of the ACL on at least a quarterly basis. The ACL represents Management's estimate of expected lifetime losses in our LHFI portfolio, excluding loans carried under the fair value option. In addition, we record a reserve for expected lifetime losses on our unfunded commitments - see Reserve for Unfunded Commitments section below. Therefore, we record ALLL on relevant financial assets and a reserve for unfunded commitments on our Consolidated Statements of Financial Condition, collectively referred to as the ACL.

Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual terms exclude expected extensions, renewals, and modifications unless the following applies: Management has a reasonable expectation at the reporting date that a TDR will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by us.

The ACL is impacted by changes in asset quality of the portfolio, including but not limited to increases in risk rating changes in our commercial portfolio, borrower delinquencies, changes in FICO scores or changes in LTVs in our consumer portfolio. In addition, while we have incorporated our forecasted impact of COVID-19 into our ACL, the ultimate impact of COVID-19 is still uncertain, including how long economic activity will be impacted by the pandemic and what effect the unprecedented levels of government fiscal and monetary actions will have on the economy and our credit losses.

Specifically identified component. The specifically identified component of ACL related to performing TDR loans is generally measured as the difference between the recorded investment in the specific loan and the present value of the cash flows expected to be collected, discounted at the loan's original effective interest rate. Estimating the timing and amounts of future cash flow projections is highly judgmental and based upon assumptions including default rates, prepayment probability and loss severities. All of these estimates and assumptions require significant management judgment and certain assumptions are highly subjective.

Specifically identified collateral dependent NPL loans are generally measured as the difference between the recorded investment in the impaired loan and the underlying collateral value less estimated costs to sell. These estimates are dependent on third-party property valuations which may be influenced by factors such as the current and future level of home prices, the duration of current overall economic conditions, and other macroeconomic and portfolio-specific factors.

Model-based component. A general allowance is established for lifetime losses inherent on non-impaired loans by segmenting the portfolio based upon common risk characteristics. Our consumer loan portfolio is segmented into Residential First Mortgage, Home Equity and Other Consumer. Loan characteristics impacting these segments include lien position, credit quality, and loan structure. At a high-level, our commercial loans are segmented into Commercial Real Estate, Commercial and Industrial, and Warehouse Lending. Loan characteristics impacting these segments include credit quality and loan structure.

We measure the allowance using the applicable dual risk rating model which measures probability of default, loss given default and exposure at default. As of December 31, 2021, we utilized the Moody’s November 2021 economic scenarios in our forecast, which were materially consistent with the December scenarios: a growth forecast, weighted at 30 percent; a baseline forecast, weighted at 40 percent; and an adverse forecast, weighted at 30 percent. Within our composite forecast, unemployment ends 2021 at 5 percent and will recover slightly in 2022, ending the year just under 5 percent. GDP continues to recover throughout 2022 and returns to pre-COVID levels in 2023. HPI decreases by just over 1 percent compared to 2021 year-end levels through the second quarter of 2022 before returning to 2021 year-end levels by the third quarter of 2022. In 2021, we judgmentally decreased our qualitative reserves by $65 million which primarily reflected our best estimates of COVID-19’s impact on our portfolios (including the estimated impact of government stimulus, forbearance/payment holidays, and Fed programs. This decline was primarily driven by a decrease in the model output from Moody’s adverse scenario, improvement in credit performance of previously identified industries and borrowers we believed could be more exposed to the stressful conditions in our forecast and decreased loans in forbearance.

Qualitative adjustments. The specifically identified component analysis and the output of the model provide a reasonable starting point for our analysis, but do not, by themselves, form a sufficient basis to determine the appropriate level for the ACL. We therefore consider the qualitative factors that are likely to cause the ACL associated with our existing portfolio to differ from the output of the model. The most significant qualitative factors considered include changes in economic and business conditions, changes in nature and volume of portfolio and changes in the volume and severity of past due loans. The application of different inputs into the model calculation and the assumptions used by Management to adjust the model calculation are subject to significant management judgment and may result in actual credit losses that differ from the originally estimated amounts.

We estimate expected credit losses over the contractual period in which we are exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by us. The ACL on unfunded commitments is adjusted as a provision for credit loss expense within the provision (benefit) for credit losses on the Consolidated Statements of

Operations and is recorded in other liabilities on the Consolidated Statements of Financial Condition. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life. The reserve for unfunded commitments is included in other liabilities on the Consolidated Statements of Financial Condition.

Our recognition of gain or loss on the sale of loans for which we surrender control is accounted for as a sale to the extent that 1) the transferred assets are legally isolated from us or our consolidated affiliates, even in bankruptcy or other receivership, 2) the transferee has the right to pledge or exchange the assets with no conditions that constrain the transferee and provide more than a trivial benefit to the Company and 3) we do not maintain the obligation or unilateral ability to reclaim or repurchase the assets. If the sale criteria are met, the transferred financial assets are removed from the Consolidated Statements of Financial Condition and a gain or loss on sale is recognized.

An entity that has a controlling financial interest in a VIE is referred to as the primary beneficiary and consolidates the VIE. An entity is deemed to have a controlling financial interest and is the primary beneficiary of a VIE if it has both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. For further information, see Note 7 - Variable Interest Entities.

Repossessed assets include one-to-four family residential property, commercial property and one-to-four family homes under construction that were acquired through foreclosure or acceptance of a deed-in-lieu of foreclosure. Repossessed assets are initially recorded in other assets at the estimated fair value of the collateral less estimated costs to sell. Losses arising from the initial acquisition of such properties are charged against the allowance for loan losses at the time of transfer. Subsequent valuation adjustments to reflect fair value, as well as gains and losses on disposal of these properties, are charged to general, administrative and other within noninterest expense in the Consolidated Statements of Operations as incurred. For further information, see Note 6 - Repossessed Assets and Note 20 - Fair Value Measurements.

We originate government guaranteed loans which are pooled and sold as Ginnie Mae MBS. Pursuant to Ginnie Mae servicing guidelines, we have the unilateral right to repurchase loans securitized in Ginnie Mae pools that are due, but unpaid, for three consecutive months. As a result, once the delinquency criteria have been met, and regardless of whether the repurchase option has been exercised, we account for the loans as if they had been repurchased. We recognize the loans and corresponding liability as loans with government guarantees and loans with government guarantees repurchase options, respectively, in the Consolidated Statements of Financial Condition. If the loan is repurchased, the liability is cash settled and the loan with government guarantee remains. Once repurchased, we work to cure the outstanding loans such that they are re-eligible for sale or may begin foreclosure and recover losses through a claims process with the government agency, as an approved lender.

Premises and equipment are carried at cost less accumulated depreciation. Land is carried at cost. Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets, which generally ranges from three to thirty years. Capitalized software is amortized on a straight-line basis over its useful life, which generally ranges from three years to seven years. Software expenditures and repair and maintenance costs that are considered general, administrative, or of a maintenance nature are expensed as incurred.

Goodwill is not amortized, but rather tested annually for impairment, or more frequently as events occur or circumstances change that would indicate the fair value is below the carrying amount. The Company may assess qualitative factors to determine whether it is more-likely-than-not the fair value is less than its carrying amount. If the Company concludes based on the qualitative assessment that goodwill may be impaired, a quantitative one-step impairment test would then be applied. An impairment loss would be recognized for any excess of carrying value over the fair value of the goodwill.

Intangible assets subject to amortization are amortized over the estimated life, using a method that approximates the time the economic benefits are realized by the Company. Intangible assets are reviewed for impairment only when there is a trigger event or changes in circumstances indicate that the carrying amount of the assets may not be recoverable.

Amortization expense on intangible assets was $11 million and $13 million for the years ended December 31, 2021 and December 31, 2020, respectively. The estimated future aggregate amortization expense on intangible assets for the years ended 2022, 2023, and 2024 is $9 million, $7 million, and $6 million respectively.

We purchase and originate mortgage loans for sale to the secondary market and sell the loans on either a servicing-retained or servicing-released basis. If we retain the right to service the loan, an MSR is created at the time of sale which is recorded at fair value. We use an internal valuation model that utilizes an option-adjusted spread, constant prepayment speeds, costs to service and other assumptions to determine the fair value of MSRs.

Management obtains third-party valuations of the MSR portfolio on a quarterly basis from independent valuation services to assess the reasonableness of the fair value calculated by our internal valuation model. Changes in the fair value of our MSRs are reported on the Consolidated Statements of Operations in net return on mortgage servicing. For further information, see Note 10 - Mortgage Servicing Rights and Note 20 - Fair Value Measurements.

We periodically enter into agreements to sell certain of our MSRs, which qualify as sales transactions. A transfer of servicing rights related to loans previously sold qualifies as a sale at the date on which title passes if substantially all risks and rewards of ownership have irrevocably passed to the transferee and any protection provisions retained by the transferor are minor and can be reasonably estimated. In addition, if a sale is recognized and only minor protection provisions exist, a liability is accrued for the estimated obligation associated with those provisions.

Effective January 1, 2019, we adopted the requirements of ASU 2016-02, Leases (Topic 842) and all related amendments. The Company elected to apply the practical expedient of forgoing the restatement of comparative periods. In addition, we elected the practical expedients permitted under transition guidance to not reassess leases entered into prior to adoption. As permitted under ASC 842, the Company made an accounting policy election to exempt leases with an initial term of twelve months or less from balance sheet recognition. Instead, short-term leases are expensed over the lease term with no impact to the balance sheet.

At December 31, 2019, our inventory of leases included various bank branches, ATM locations and retail home lending offices. Many of our leases contain options to extend or terminate early and we consider these options when evaluating the lease term to determine if they are reasonably certain to be exercised based on all relevant economic and financial factors. Lease rental expense totaled approximately $15 million, $13 million, and $12 million for the years ended December 31, 2021, 2020 and 2019, respectively. All leases are classified as operating leases based on their terms.

Servicing fee income, late fees and ancillary fees received on loans for which we own the MSR are included in net return on mortgage servicing rights on the Consolidated Statements of Operations. The fees are based on the outstanding principal and are recorded as income when earned. Subservicing fees, which are included in loan administration income on the Consolidated Statements of Operations, are based on a contractual monthly amount per loan including late fees and other ancillary income.

Deposit account and other banking income - We charge depositors various deposit account service fees including those for outgoing wires, overdrafts, stop payments, and ATM fees. These fees are generated from a depositor’s option to purchase services offered under the contract and are only considered a contract when the depositor exercises their option to purchase these account services. Therefore, we deem the term of our contracts with depositors to be day-to-day and do not extend beyond the services already provided. Deposit account and other banking fees are recorded at the point in time we perform the requested service.

Merchant fee income - We receive a percentage of merchant fees based upon card transactions processed through point-of-sale terminals at referred merchant locations. Our performance obligation is satisfied when our referral of a merchant to a payment processing vendor results in an executed agreement between the merchant and the vendor. Merchant fee revenue is recognized as received.

Wealth management revenue - We earn commission income through a revenue share program based on a tiered percentage of total gross commissions generated from the sales of investment and insurance services to Flagstar customers. Commissions are earned and our performance obligation has been satisfied at the point of sale or trade execution. Our portion of earned commissions is calculated, paid and recognized as revenue on a monthly basis.

We also earn revenue from portfolio management services. We receive payment in advance for portfolio management services at the beginning of each quarter for services to be performed over the quarter which results an insignificant revenue liability. We recognize this revenue over the quarter on a straight-line basis, as we believe this is the most appropriate method to measure progress towards satisfaction of the performance obligation.

We utilize derivative instruments to manage the fair value changes in our MSRs, interest rate lock commitments and LHFS portfolio which are exposed to price and interest rate risk; facilitate asset/liability management; minimize the variability of future cash flows on long-term debt; and to meet the needs of our customers. All derivatives are recognized on the Consolidated Statements of Financial Condition as other assets and liabilities, as applicable, at their estimated fair value.

For those derivatives designated as qualified cash flow hedges, changes in the fair value of the derivatives, to the extent effective as a hedge, are recorded in accumulated other comprehensive income, net of income taxes, and reclassified into earnings concurrently with the earnings of the hedged item. For derivative instruments designated as qualified fair value hedges, which are used to hedge the exposure of fair value changes of an asset or liability attributable to a particular risk, the gain or loss on the derivative instrument, as well as the offsetting gain or loss on the hedged item attributable to the hedged risk, are recognized in current earnings during the period. For all other derivatives, changes in the fair value of the derivative are recognized immediately in earnings. A majority of these derivatives are subject to master netting agreements and cleared through a Central Counterparty Clearing House, which mitigates non-performance risk with counterparties and enables us to settle activity on a net basis.

We also enter into various derivative agreements with customers and correspondents in the form of interest rate lock commitments and forward purchase contracts which are commitments to originate or purchase mortgage loans whereby the interest rate on the loan is determined prior to funding and the customers have locked into that interest rate. The derivatives are valued using internal models that utilize market interest rates and other unobservable inputs. Changes in the fair value of these commitments due to fluctuations in interest rates are economically hedged through the use of forward loan sale commitments of MBS. The gains and losses arising from this derivative activity are reflected in current period earnings under the net gain on loan sales.

We may utilize interest rate swaps to hedge the forecasted cash flows from our underlying variable-rate FHLB advances and forecasted FHLB advances in qualifying cash flow hedge accounting relationships. Changes in the fair value of derivatives designated as cash flow hedges are recorded in other comprehensive income on the Consolidated Statement of Financial Condition and reclassified into interest expense concurrently with the interest expense on the debt. Interest rate swaps are valued based on quoted prices for similar assets in an active market with inputs that are observable. These hedges are evaluated for effectiveness using regression analysis at the time they are designated and then qualitatively throughout the remaining hedge period unless a change in facts and circumstances is identified. For forecasted FHLB advances being hedged, we evaluate the likelihood of the transaction occurring based on the current facts and circumstances each reporting period to ensure the hedge relationship still qualifies for hedge accounting. If we de-designate a hedge relationship or determine that an interest rate swap no longer qualifies for hedge accounting, changes in fair value are no longer recorded in other comprehensive income. The effective amounts previously recorded in other comprehensive income are recognized in earnings over the remaining life of the hedged item as an adjustment to yield, until the point it is determined that the underlying transaction is probable to not occur, at which point it is reclassified immediately into earnings.

We utilize interest rate swaps to manage fair value changes of our fixed-rate FHLB advances, certain HFI residential first mortgages and certain AFS securities in qualifying fair value hedge accounting relationships. Interest rate swaps are valued based on quoted prices for similar assets in an active market with inputs that are observable. Changes in the fair value of derivatives designated as fair value hedges, and changes in value attributable to the benchmark interest rate of the hedged item, are recognized in current period earnings and as a basis adjustment to the hedged item and hedging instrument. These hedges are evaluated for effectiveness using regression analysis at the time they are designated and then qualitatively throughout the hedge period unless a change in facts and circumstances is identified. If the Company determines an interest rate swap no longer qualifies for fair value hedge accounting or is de-designated, the hedged item will no longer be adjusted for changes in fair value and the amounts previously recorded as a basis adjustment are recognized in earnings over the remaining life of the hedged item as an adjustment to yield. If a previously hedged item is extinguished or sold, the remaining basis adjustment of the hedged item for prior fair value hedges will be reclassified to current period earnings.

Current income tax expense represents our estimated taxes to be paid or refunded for the current period. Deferred taxes are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. DTAs and liabilities are measured using enacted tax rates that will apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on DTAs and liabilities of a change in tax rates is recognized as income or expense in the period that includes the enactment date. We evaluate our DTAs to determine if, based on all available evidence, it is more likely than not that they will be realized. If it is determined that it is more likely than not that the deferred taxes will not be realized, we establish a valuation allowance. For further information, see Note 17 - Income Taxes.

When we sell mortgage loans into the secondary mortgage market, we make customary representations and warranties to the purchasers about various characteristics of each loan. Upon the sale of a loan, we recognize a liability for that guarantee at its fair value as a reduction of our net gain on loan sales. Subsequent to the sale, the liability is re-measured on an ongoing basis based upon an estimate of probable future losses. An estimate of the fair value of the guarantee associated with the mortgage loans is recorded in other liabilities in the Consolidated Statements of Financial Condition, and was $4 million at December 31, 2021, as compared to $7 million at December 31, 2020.

Advertising costs are expensed in the period they are incurred and are included as part of general, administrative and other noninterest expense in the Consolidated Statements of Operations. Advertising expenses totaled $26 million, $22 million, and $25 million, for the years ended December 31, 2021, 2020 and 2019, respectively.

All share-based payments to employees, including restricted stock units, are classified as equity with expenses being recognized in compensation and benefits in the Consolidated Statements of Operations based on their fair values. The amount of compensation is measured at the grant date and is expensed over the requisite service period, which is normally the vesting period with forfeitures being recognized as they occur. In addition to share-based payments to employees, the discount provided to employees through the Employee Stock Purchase Plan is also recognized as stock-based compensation. For further information, see Note 16 - Stock-Based Compensation.

Credit Losses - Effective January 1, 2020, we have adopted the requirements of ASU 2016-13, Financial Instruments – Credit Losses (Topic 326) and all related amendments using the modified retrospective method for all financial assets measured at amortized cost, net investments in leases and unfunded commitments. The measurement of current expected credit losses should be based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. 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. We recorded a net decrease to retained earnings of $23 million as of January 1, 2020 for the cumulative effect of adopting ASC 326.
