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 </span><span style="font-family:Arial;font-size:10pt;"><span>180</span></span><span style="font-family:Arial;font-size:10pt;"> 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="line-height:120%;padding-bottom:16px;padding-top:16px;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We resume accruing interest on non-credit card loans when the customer’s account is less than </span><span style="font-family:Arial;font-size:10pt;"><span>90</span></span><span style="font-family:Arial;font-size:10pt;"> days past due and collection of such amounts is probable.

See Note 4. </span><span style="font-family:Arial;font-size:10pt;font-style:italic;">Loan Receivables and Allowance for Loan Losses</span><span style="font-family:Arial;font-size:10pt;"> for further detail. </span></div>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.

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.
