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 the effects of COVID-19 and 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, 2020 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.</span></div><div style="margin-bottom:12pt;margin-top:12pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">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.</span></div><div style="margin-bottom:12pt;margin-top:12pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">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 payments from an account do not exceed the measurement date balance.</span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">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. The current and forecasted economic conditions due to the COVID-19 pandemic influenced our current estimate of expected credit losses and led to the increase in the estimate since adoption. Additionally, the estimate of expected credit losses includes expected recoveries of amounts previously charged off and expected to be charged off.</span></div><div style="margin-bottom:12pt;margin-top:12pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">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 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. </span></div><div><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">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. </span></div><div style="margin-bottom:12pt;margin-top:12pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">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. Under the CARES Act, banks may elect to deem that loan modifications do not result in TDRs if they are (1) related to the novel coronavirus disease (“COVID-19”); (2) executed on a loan that was not more than 30 days past due as of December 31, 2019; and (3) executed between March 1, 2020, and the earlier of (A) 60 days after the date of termination of the National Emergency or (B) January 1, 2022. At December 31, 2020, we have not made such an election. Additionally, other short-term modifications made on a good faith basis in response to COVID-19 are not considered TDRs under ASC Subtopic 310-40. This includes delays in payment that are insignificant or short-term (e.g., up to six months) modifications such as payment deferrals, fee waivers or extensions of repayment terms to borrowers who were current prior to any relief. Borrowers considered current are those that are less than 30 days past due on their contractual payments at the time a modification program is implemented.</span></div>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 and non-accrual loan, and be included in each of these categories. The categorization of a particular loan also may not be indicative of the potential for loss.

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. </span></div><div style="margin-bottom:12pt;margin-top:12pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">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.</span></div><div style="margin-bottom:12pt;margin-top:12pt"><span style="color:#000000;font-family:'Arial',sans-serif;font-size:10pt;font-weight:400;line-height:120%">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.

CY2020	us-gaap	Revenue Recognition Loyalty Programs RevenueRecognitionLoyaltyPrograms	Loyalty ProgramsOur 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. These programs are primarily in our Retail Card platform. 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.
