In April 2013, we moved all closed-end real estate secured receivables onto one platform which resulted in the substantial majority of our real estate secured receivables utilizing the same platform. While we experienced an increase in dollars of two-months-and-over contractual delinquency as of June 30, 2013 for the receivables that were moved to the different platform, much of the increase has been offset by improvements in credit quality in other parts of our real estate secured receivable portfolio.2Receivables less than 30 days past due are presented as current.3The receivable balances included in this table reflects the principal amount outstanding on the loan and certain basis adjustments to the loan such as deferred fees and costs on originated loans, purchase accounting fair value adjustments and premiums or discounts on purchased loans. However, these basis adjustments on the loans are excluded in other presentations of dollars of two-months-and-over contractual delinquency and nonperforming receivable account balances.falseReceivables - Aging Analysis of Past Due Loans (Detail) (USD $)MillionsUnKnownUnKnownUnKnowntruefalsefalseSheethttp://www.us.hsbc.com/role/ReceivablesAgingAnalysisOfPastDueLoansDetail86
