Basis of Presentation and Summary of Significant Accounting Policies | BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying consolidated financial statements were prepared in conformity with U.S. generally accepted accounting principles (“GAAP”). Preparing financial statements in conformity with U.S. GAAP requires us to make estimates based on assumptions about current, and for some estimates, future, economic and market conditions (for example, unemployment, housing, interest rates and market liquidity) which affect reported amounts and related disclosures in our consolidated financial statements. Although our current estimates contemplate current conditions and how we expect them to change in the future, as appropriate, it is reasonably possible that actual conditions could be different than anticipated in those estimates, which could materially affect our results of operations and financial position. Among other effects, such changes could result in incremental losses on loan receivables, future impairments of debt securities, goodwill and intangible assets, increases in reserves for contingencies, establishment of valuation allowances on deferred tax assets and increases in our tax liabilities. We primarily conduct our business within the United States and Canada and substantially all of our revenues are from U.S. customers. The operating activities conducted by our non-U.S. affiliates use the local currency as their functional currency. The effects of translating the financial statements of these non-U.S. affiliates to U.S. dollars are included in equity. Asset and liability accounts are translated at period-end exchange rates, while revenues and expenses are translated at average rates for the respective periods. Consolidated Basis of Presentation The Company’s financial statements have been prepared on a consolidated basis. Under this basis of presentation, our financial statements consolidate all of our subsidiaries – i.e., entities in which we have a controlling financial interest, most often because we hold a majority voting interest. To determine if we hold a controlling financial interest in an entity, we first evaluate if we are required to apply the variable interest entity (“VIE”) model to the entity, otherwise the entity is evaluated under the voting interest model. Where we hold current or potential rights that give us the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance (“power”) combined with a variable interest that gives us the right to receive potentially significant benefits or the obligation to absorb potentially significant losses (“significant economics”), we have a controlling financial interest in that VIE. Rights held by others to remove the party with power over the VIE are not considered unless one party can exercise those rights unilaterally. We consolidate certain securitization entities under the VIE model because we have both power and significant economics. See Note 5. Variable Interest Entities . New Accounting Standards Recently Issued But Not Yet Adopted Accounting Standards In March 2022, the FASB issued ASU No. 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. This ASU eliminates the separate recognition and measurement guidance for Troubled Debt Restructurings (“TDRs”) by creditors. The elimination of the TDR guidance may be adopted prospectively for loan modifications after adoption or on a modified retrospective basis, which would also apply to loans previously modified, resulting in a cumulative effect adjustment to retained earnings in the period of adoption for changes in the allowance for credit losses. The Company will adopt this guidance on its effective date, which for us is January 1, 2023, on a modified retrospective basis. Based on our current stage of implementation, we estimate the adoption will result in a decrease of approximately $0.3 billion, or 3%, to the Company's allowance for credit losses. Segment Reporting We conduct our operations through a single business segment. Substantially all of our interest and fees on loans and long-lived assets relate to our operations within the United States. Pursuant to FASB Accounting Standards Codification (“ASC”) 280, Segment Reporting , operating segments represent components of an enterprise for which separate financial information is available that is regularly evaluated by the chief operating decision maker in determining how to allocate resources and in assessing performance. The chief operating decision maker uses a variety of measures to assess the performance of the business as a whole, depending on the nature of the activity. Revenue activities are primarily managed through five sales platforms (Home & Auto, Digital, Diversified & Value, Health & Wellness and Lifestyle). Those platforms are organized by the types of partners we work with to reach our customers, with success principally measured based on interest and fees on loans, loan receivables, active accounts and other sales metrics. Detailed profitability information of the nature that could be used to allocate resources and assess the performance and operations for each sales platform individually, however, is not used by our chief operating decision maker. Expense activities, including funding costs, credit losses and operating expenses, are not measured for each platform but instead are managed for the Company as a whole. Cash and Equivalents Debt securities, money market instruments and bank deposits with original maturities of three months or less are included in cash and equivalents unless designated as available-for-sale and classified as debt securities. Cash and equivalents at December 31, 2022 primarily included cash and due from banks of $1.5 billion and interest-bearing deposits in other banks of $8.8 billion. Cash and equivalents at December 31, 2021 primarily included cash and due from banks of $1.5 billion and interest-bearing deposits in other banks of $6.8 billion. Restricted Cash and Equivalents Restricted cash and equivalents represent cash and equivalents that are not available to us due to restrictions related to its use. In addition, our securitization entities are required to fund segregated accounts that may only be used for certain purposes, including payment of interest and servicing fees and repayment of maturing debt. We include our restricted cash and equivalents in other assets in our Consolidated Statements of Financial Position. Investment Securities We report investments in debt securities and equity securities with a readily determinable fair value at fair value. See Note 9. Fair Value Measurements for further information on fair value. Changes in fair value on debt securities, which are classified as available-for-sale, are included in equity, net of applicable taxes. Changes in fair value on equity securities are included in earnings. We regularly review investment securities for impairment using both quantitative and qualitative criteria. For debt securities, if we do not intend to sell the security, or it is not more likely than not, that we will be required to sell the security before recovery of our amortized cost, we evaluate other qualitative criteria to determine whether we do not expect to recover the amortized cost basis of the security, such as the financial health of, and specific prospects for the issuer, including whether the issuer is in compliance with the terms and covenants of the security. We also evaluate quantitative criteria including determining whether there has been an adverse change in expected future cash flows. If we do not expect to recover the entire amortized cost basis of the security, we consider the debt security to be impaired. If the security is impaired, we determine whether the impairment is the result of a credit loss or other factors. If a credit loss exists, an allowance for credit losses is recorded, with a related charge to earnings, limited by the amount that the fair value of the security is less than its amortized cost. Given the nature of our current portfolio, we perform a qualitative assessment to determine whether any credit loss is warranted. The assessment considers factors such as adverse conditions and payment structure of the securities, history of payment, and market conditions. If we intend to sell the security or it is more likely than not we will be required to sell the debt security before recovery of its amortized cost basis, the security is also considered impaired and we recognize the entire difference between the security’s amortized cost basis and its fair value in earnings. Realized gains and losses are accounted for on the specific identification method. Loan Receivables Loan receivables primarily consist of open-end consumer revolving credit card accounts, closed-end consumer installment loans and open-end commercial revolving credit card accounts. Loan receivables are reported at the amounts due from customers, including unpaid interest and fees, deferred income and costs. Loan Receivables Held for Sale Loans purchased or originated with the intent to sell are classified as loan receivables held for sale and carried at the lower of amortized cost or fair value. Loans initially classified as held for investment are transferred to loan receivables held for sale and carried at the lower of amortized cost or fair value once a decision has been made to sell the loans. We continue to recognize interest and fees on these loans on the accrual basis. The fair value of loan receivables held for sale is determined on an aggregate homogeneous portfolio basis. If a loan is transferred from held for investment to held for sale, any associated allowance for credit loss is reversed through earnings, and the loan is transferred to held for sale at amortized cost. The amount by which amortized cost basis exceeds fair value is accounted for as a valuation allowance. The loan is carried at the lower of amortized cost or fair value. Acquired Loans To determine the fair value of loans at acquisition, we estimate expected cash flows and discount those cash flows using an observable market rate of interest, when available, adjusted for factors that a market participant would consider in determining fair value. In determining fair value, expected cash flows are adjusted to include prepayment, default rate, and loss severity estimates. The difference between the fair value and the amount contractually due is recorded as a loan discount or premium at acquisition. Loans acquired that have experienced more-than-insignificant deterioration in credit quality since origination (referred to as “purchased credit deteriorated” or “PCD” assets) are subject to specific guidance upon acquisition. An allowance for PCD assets is added to the purchase price or fair value of the acquired loans to arrive at the amortized cost basis. Subsequent to initial recognition, the accounting for the PCD asset will generally follow the credit loss model described below. Loans acquired without a more-than-insignificant credit deterioration since origination are measured under the Allowance for Credit Losses model described below. Allowance for Credit Losses In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments (Topic 326). This ASU replaced the existing incurred loss impairment guidance with a new impairment framework known as Current Expected Credit Loss ("CECL"). We adopted this guidance on a modified retrospective basis as of January 1, 2020, which resulted in the recognition of the effects of adoption through a cumulative-effect adjustment to retained earnings. As a result of adoption, we incurred an increase of $3.0 billion to the Company’s allowance for loan losses. This guidance also applies to other financial assets, such as our debt securities, however the adoption did not have an impact on these financial statement line items. The total impact of adoption resulted in a reduction to retained earnings in our Consolidated Statement of Financial Position of $2.3 billion, reflecting the above changes and the recognition of related additional deferred tax assets. Subsequent updates to our estimate of expected credit losses have been recorded through the provision for credit losses in our Consolidated Statement of Earnings. Losses on loan receivables are estimated and recognized upon origination of the loan, based on expected credit losses for the life of the loan balance as of the period end date. Expected credit loss estimates involve modeling loss projections attributable to existing loan balances, considering historical experience, current conditions and future expectations for pools of loans with similar risk characteristics over the reasonable and supportable forecast period. The model utilizes a macroeconomic forecast, with unemployment claims as the primary macroeconomic variable. We also perform a qualitative assessment in addition to model estimates and apply qualitative adjustments as necessary. The reasonable and supportable forecast period is determined primarily based upon an assessment of the current economic outlook, including our ability to use available data to accurately forecast losses over time. The reasonable and supportable forecast period used in our estimate of credit losses at December 31, 2022 was 12 months, consistent with the forecast period utilized since adoption of CECL. The Company reassesses the reasonable and supportable forecast period on a quarterly basis. Beyond the reasonable and supportable forecast period, we revert to historical loss information at the loan receivables segment level over a 6-month period, gradually increasing the weight of historical losses by an equal amount each month during the reversion period, and utilize historical loss information thereafter for the remaining life of the portfolio. The historical loss information is derived from a combination of recessionary and non-recessionary performance periods, weighted by the time span of each period. Similar to the reasonable and supportable forecast period, we also reassess the reversion period and historical mean on a quarterly basis, considering any required adjustments for differences in underwriting standards, portfolio mix, and other relevant data shifts over time. We generally segment our loan receivable population into pools of loans with similar risk characteristics at the major retailer and product level. Consistent with our other assumptions, we regularly review segmentation to determine whether the segmentation pools remain relevant as risk characteristics change. Our loan receivables generally do not have a stated life. The life of a credit card loan receivable is dependent upon the allocation of payments received, as well as a variety of other factors, including the principal balance, promotional terms, interest charges and fees and overall consumer credit profile and usage pattern. We determine the expected credit losses for credit card loan receivables as of the measurement date by using a combination of migration analysis, and other historical analyses, which implicitly consider the payments attributable to the measurement date balance. To do so, we utilize an approach which implicitly considers total expected future payments and applies appropriate allocations to reduce those payments in order to estimate losses pertaining to measurement date loan receivables. Based on our payments analyses, we also ensure that expected future payments from an account do not exceed the measurement date balance. We evaluate each portfolio quarterly. For credit card receivables, our estimation process includes analysis of historical data, and there is a significant amount of judgment applied in selecting inputs and analyzing the results produced by the models to determine the allowance for credit losses. We use an enhanced migration analysis to estimate the likelihood that a loan will progress through the various stages of delinquency. The enhanced migration analysis considers uncollectible principal, interest and fees reflected in the loan receivables, segmented by credit and business parameters. We use other analyses to estimate expected losses on non-delinquent accounts, which include past performance, bankruptcy activity such as filings, policy changes and loan volumes and amounts. Holistically, for assessing the portfolio credit loss content, we also evaluate portfolio risk management techniques applied to various accounts, historical behavior of different account vintages, account seasoning, economic conditions, recent trends in delinquencies, account collection management, forecasting uncertainties, expectations about the future and a qualitative assessment of the adequacy of the allowance for credit losses. Key factors that impact the accuracy of our historical loss forecast estimates include the models and methodology utilized, credit strategy and trends, and consideration of material changes in our loan portfolio such as changes in growth and portfolio mix. We regularly review our collection experience (including delinquencies and net charge-offs) in determining our allowance for credit losses. We also consider our historical loss experience to date based on actual defaulted loans and overall portfolio indicators including delinquent and non-accrual loans, trends in loan volume and lending terms, credit policies and other observable environmental factors such as unemployment and home price indices. Additionally, the estimate of expected credit losses includes expected recoveries of amounts previously charged-off and expected to be charged-off. The underlying assumptions, estimates and assessments we use to provide for losses are updated periodically to reflect our view of current and forecasted conditions, and are subject to the regulatory examination process, which can result in changes to our assumptions. Changes in such estimates can significantly affect the allowance and provision for credit losses. It is possible that we will experience credit losses that are different from our current estimates. Charge-offs are deducted from the allowance for credit losses and are recorded in the period when we judge the principal to be uncollectible, and subsequent recoveries are added to the allowance, generally at the time cash is received on a charged-off account. Delinquent receivables are those that are 30 days or more past due based on their contractual payments. Non-accrual loan receivables are those on which we have stopped accruing interest. We continue to accrue interest until the earlier of the time at which collection of an account becomes doubtful, or the account becomes 180 days past due, with the exception of non-credit card accounts, for which we stop accruing interest in the period that the account becomes 90 days past due. Troubled debt restructurings (“TDR”) are those loans for which we have granted a concession to a borrower experiencing financial difficulties where we do not receive adequate compensation. TDRs are identified at the point when the borrower enters into a modification program. The same loan receivable may meet more than one of the definitions above. Accordingly, these categories are not mutually exclusive, and it is possible for a particular loan to meet the definitions of a TDR, a non-accrual loan and a delinquent loan, and be included in each of these categories. The categorization of a particular loan also may not necessarily be indicative of the potential for loss. Loan Modifications and Restructurings Our loss mitigation strategy is intended to minimize economic loss and, at times, can result in rate reductions, principal forgiveness, extensions or other actions, which may cause the related loan to be classified as a TDR. We primarily use long-term modification programs for borrowers experiencing financial difficulty as a loss mitigation strategy to improve long-term collectability of the loans that are classified as TDRs. The long-term modification programs include changing the structure of the loan to a fixed payment loan with a maturity no longer than 60 months, reducing the interest rate on the loan, and stopping the assessment of penalty fees. We also make long-term loan modifications for customers who request financial assistance through external sources, such as through consumer credit counseling service agencies. Long-term loan modification programs do not normally include the forgiveness of unpaid principal, interest or fees. The determination of whether these changes to the terms and conditions meet the TDR criteria includes our consideration of all relevant facts and circumstances. See Note 4. Loan Receivables and Allowance for Credit Losses for additional information on our loan modifications and restructurings. Our allowance for credit losses on TDRs is generally measured based on the difference between the recorded loan receivable and the present value of the expected future cash flows, discounted at the original effective interest rate of the loan. If the loan is collateral dependent, we measure impairment based upon the fair value of the underlying collateral less estimated selling costs. Data related to redefault experience is also considered in our overall reserve adequacy review. Once the loan has been modified, it only returns to current status (re-aged) after three consecutive monthly program payments are received post the modification date, subject to re-aging limitations in the Federal Financial Institutions Examination Council guidelines on Uniform Retail Credit Classification and Account Management policy issued in June 2000. Charge-Offs Net charge-offs consist of the unpaid principal balance of loans held for investment that we determine are uncollectible, net of recovered amounts. We exclude accrued and unpaid finance charges, fees and third-party fraud losses from charge-offs. Charged-off and recovered accrued and unpaid finance charges and fees are included in interest and fees on loans while fraud losses are included in other expense. Charge-offs are recorded as a reduction to the allowance for credit losses, and subsequent recoveries of previously charged-off amounts are credited to the allowance for credit losses. Costs incurred to recover charged-off loans are recorded as collection expense and are included in other expense in our Consolidated Statements of Earnings. We charge-off unsecured closed-end consumer installment loans and loans secured by collateral when they are 120 days contractually past due, and unsecured open-ended revolving loans when they are 180 days contractually past due. Unsecured consumer loans in bankruptcy are charged-off within 60 days of notification of filing by the bankruptcy court or within contractual charge-off periods, whichever occurs earlier. Credit card loans of deceased account holders are charged-off within 60 days of receipt of notification. Goodwill and Intangible Assets We do not amortize goodwill but test it at least annually for impairment at the reporting unit level pursuant to ASC 350, Intangibles—Goodwill and Other . A reporting unit is defined under GAAP as the operating segment, or one level below that operating segment (the component level) if discrete financial information is prepared and regularly reviewed by segment management. Our single operating segment comprises a single reporting unit, based on the level at which segment management regularly reviews and measures the business operating results. Goodwill impairment risk is first assessed by performing a qualitative review of entity-specific, industry, market and general economic factors for our reporting unit. If potential goodwill impairment risk exists that indicates that it is more likely than not that the carrying value of our reporting unit exceeds its fair value, a quantitative test is performed. The quantitative test compares the reporting unit’s estimated fair value with its carrying value, including goodwill. If the carrying value of our reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to that excess, limited to the amount of goodwill allocated to the reporting unit. The qualitative assessment for each period presented in the consolidated financial statements was performed without hindsight, assuming only factors and market conditions existing as of those dates, and resulted in no potential goodwill impairment risk for our reporting unit. Consequently, goodwill was not deemed to be impaired for any of the periods presented. Definite-lived intangible assets principally consist of certain costs incurred to develop or acquire capitalized software and customer-related assets including contract acquisition costs and purchased credit card relationships. Capitalized software is amortized on a straight-line basis over its estimated useful life, generally 5 years. Customer-related assets are amortized over their estimated useful lives. Defined-lived intangible assets are evaluated for impairment whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable. The evaluation compares the cash inflows expected to be generated from each intangible asset to its carrying value. If cash flows attributable to the intangible asset are less than the carrying value, the asset is considered impaired and written down to its estimated fair value. Revenue Recognition Interest and Fees on Loans We use the effective interest method to recognize income on loans. Interest and fees on loans is comprised largely of interest and late fees on credit card and other loans. Interest income is recognized based upon the amount of loans outstanding and their contractual interest rate. Late fees are recognized when billable to the customer. We continue to accrue interest and fees on credit cards until the accounts are charged-off in the period the account becomes 180 days past due. For non-credit card loans, we stop accruing interest and fees when the account becomes 90 days past due. Previously recognized interest income that was accrued but not collected from the customer is reversed. Although we stop accruing interest in advance of payments, we recognize interest income as cash is collected when appropriate, provided the amount does not exceed that which would have been earned at the historical effective interest rate; otherwise, payments received are applied to reduce the principal balance of the loan. We resume accruing interest on non-credit card loans when the customer’s account is less than 90 days past due and collection of such amounts is probable. Interest accruals on modified loans that are not considered to be TDRs may return to current status (re-aged) only after receipt of at least three consecutive minimum monthly payments subject to a re-aging limitation of once a year, or twice in a five-year period. Direct loan origination costs on credit card loans are deferred and amortized on a straight-line basis over a one-year period, or the life of the loan for other loan receivables, and are included in interest and fees on loans in our Consolidated Statements of Earnings. See Note 4. Loan Receivables and Allowance for Credit Losses for further detail. Other loan fees including miscellaneous fees charged to borrowers are recognized net of waivers and charge-offs when the related transaction or service is provided, and are included in other income in our Consolidated Statements of Earnings. Promotional Financing Loans originated with promotional financing may include deferred interest financing (interest accrues during a promotional period and becomes payable if the full purchase amount is not paid off during the promotional period), no interest financing (no interest accrues during a promotional period but begins to accrue thereafter on any outstanding amounts at the end of the promotional period) and reduced interest financing (interest accrues monthly at a promotional interest rate during the promotional period). For deferred interest financing, we bill interest to the borrower, retroactive to the inception of the loan, if the loan is not repaid prior to the specified date. Income is recognized on such loans when it is billable. In almost all cases, our retail partner will pay an upfront fee or reimburse us to compensate us for all or part of the costs associated with providing the promotional financing. Upfront fees are deferred and accreted to income over the promotional period. Reimbursements are estimated and accrued as income over the promotional period. Purchased Loans Loans acquired by purchase are recorded at fair value, which may result in the recognition of a loan premium or loan discount. For acquired loans with evidence of more-than-insignificant deterioration in credit quality since origination, the initial allowance for credit losses at acquisition is added to the purchase price to determine the initial cost basis of the loans and loan premium or loan discount. Loan premiums and loan discounts are recognized into interest income over the estimated remaining life of the loans. The Company develops an allowance for credit losses for all purchased loans, which is recognized upon acquisition, similar to that of an originated financial asset. Subsequent changes to the expected credit losses for these loans follow the allowance for credit losses methodology described above under “—Allowance for Credit Losses.” Retailer Share Arrangements Most of our program agreements with large retail and certain other partners contain retailer share arrangements that provide for payments to our partners if the economic performance of the program exceeds a contractually defined threshold. We also provide other economic benefits to our partners such as royalties on purchase volume or payments for new accounts, in some cases instead of retailer share arrangements (for example, on our co-branded credit cards). Although the share arrangements vary by partner, these arrangements are generally structured to measure the economic performance of the program, based typically on agreed upon program revenues (including interest income and certain other income) less agreed upon program expenses (including interest expense, provision for credit losses, retailer payments and operating expenses), and share portions of this amount above a negotiated threshold. These thresholds and the economic performance of a program are based on, among other things, agreed upon measures of program expenses. On a quarterly basis, we make a judgment as to whether it is probable that the performance threshold will be met under a particular retail partner’s retailer share arrangement. The current period’s estimated contribution to that ultimate expected payment is recorded as a liability. To the extent facts and circumstances change and the cumulative probable payment for prior months has changed, a cumulative adjustment is made to align the retailer share arrangement liability balance with the amount considered probable of being paid relating to past periods. Loyalty Programs Our loyalty programs are designed to generate increased purchase volume per customer while reinforcing the value of our credit cards and strengthening cardholder loyalty. These programs typically provide cardholders with statement credit or cash back rewards. Other programs include rewards points, which are redeemable for a variety of products or awards, or merchandise discounts that are earned by achieving a pre-set spending level on their private label credit card, Dual Card or general purpose co-branded credit card. We establish a rewards liability based on points and merchandise discounts earned that are ultimately expected to be redeemed and the average cost per point at redemption. The rewards liability is included in accrued expenses and other liabilities in our Consolidated Statements of Financial Position. Cash rebates are earned based on a tiered percentage of purchase volume. As points and discounts are redeemed or cash rebates are issued, the rewards liability is relieved. The estimated cost of loyalty programs is classified as a reduction to other income in our Consolidated Statements of Earnings. Fraud Losses We experience third-party fraud losses from the unauthorized use of credit cards and when loans are obtained through fraudulent means. Fraud losses are included as a charge within other expense in our Consolidated Statements of Earnings, net of recoveries, when such losses are probable. Loans are charged-off, as applicable, after the i |
