The Household Debt Service Ratio (DSR) (https://fred.stlouisfed.org/series/TDSP) is the ratio of total required household debt payments to total disposable income. The DSR is divided into two parts. The Mortgage DSR (MDSP) (https://fred.stlouisfed.org/series/MDSP) is total quarterly required mortgage payments divided by total quarterly disposable personal income. The Consumer DSR (CDSP) (https://fred.stlouisfed.org/series/CDSP) is total quarterly scheduled consumer debt payments divided by total quarterly disposable personal income. The Mortgage DSR and the Consumer DSR sum to the DSR. For more information, please visit the Board of Governors (https://www.federalreserve.gov/releases/housedebt/about.htm).

The AD&Co US Mortgage High Yield Index crOAS, credit-and-option-adjusted spread, is an extension of the traditional OAS measure. On a set of 20 standardized, probabilistically weighted, market-and-model stress scenarios, AD&Co computes a discount rate that equates expected present value of tranche's cash flows to the observed market price; the cash flows are loss-adjusted using AD&Co's LoanDynamics Model (LDM). Investors and fund managers can use the index to assess the broad market returns, risks and opportunities available through investing in a market-weighted, passive portfolio of US mortgage credit risk transfer instruments. The Index also provides a means of comparing the returns of an actively managed portfolio against a passive, naive market portfolio as approximated by the Index. The Mid-Tier and its sub-indices allow for approximations of performance comparisons by vintage or age, across the capital stack, and by initial credit risk level and/or vintage as indicated by original attachment point. <b>Disclaimer:</b> The AD&Co U.S. Mortgage High-Yield Index serves as an informational index and is not for commercial-use purposes.

Until February of 2022, AD&Co has been computing crOAS relative to the Libor-swap rate curve that is set to retire in 2023. Following the prevailing market trend and starting from its February-end report, AD&Co began computing the crOAS metric relative to the Treasury-curve benchmark. Given the differences between the two rate curves, this change should account for approximately 6 to 12 bps widening in spread for the AD&Co CRT Indices. <b>Disclaimer:</b> The AD&Co U.S. Mortgage High-Yield Index serves as an informational index and is not for commercial-use purposes.

The AD&Co US Mortgage High Yield Index crOAS, credit-and-option-adjusted spread, is an extension of the traditional OAS measure. On a set of 20 standardized, probabilistically weighted, market-and-model stress scenarios, AD&Co computes a discount rate that equates expected present value of tranche's cash flows to the observed market price; the cash flows are loss-adjusted using AD&Co's LoanDynamics Model (LDM). Investors and fund managers can use the index to assess the broad market returns, risks and opportunities available through investing in a market-weighted, passive portfolio of US mortgage credit risk transfer instruments. The Index also provides a means of comparing the returns of an actively managed portfolio against a passive, naive market portfolio as approximated by the Index. The Mid-Tier and its sub-indices allow for approximations of performance comparisons by vintage or age, across the capital stack, and by initial credit risk level and/or vintage as indicated by original attachment point. Until February of 2022, AD&Co has been computing crOAS relative to the Libor-swap rate curve that is set to retire in 2023. Following the prevailing market trend and starting from its February-end report, AD&Co began computing the crOAS metric relative to the Treasury-curve benchmark. Given the differences between the two rate curves, this change should account for approximately 6 to 12 bps widening in spread for the AD&Co CRT Indices. <b>Disclaimer:</b> The AD&Co U.S. Mortgage High-Yield Index serves as an informational index and is not for commercial-use purposes.

The AD&Co US Mortgage High Yield Index (USMHY) tracks the total return of the bonds issued within the CRT programs of Fannie Mae and Freddie Mac. USMHY is an informational, investment-oriented monthly index of the return components: price, coupon, paydown, and credit loss. Accompanied by standard risk metrics from our models, the index is useful for comparisons with individual CRT bonds or relative value to other credit markets. Investors and fund managers can use the index to assess the broad market returns, risks and opportunities available through investing in a market-weighted, passive portfolio of US mortgage credit risk transfer instruments. The Index also provides a means of comparing the returns of an actively managed portfolio against a passive, naive market portfolio as approximated by the Index.

The 75th percentile original loan-to-value (LTV) ratio. The original LTV ratio is the original loan amount divided by the lesser of the selling price or the appraised value of the property securing the mortgage at origination. Only mortgage accounts with LTV values greater than 0 percent and less than 125 percent are included in the original LTV percentile calculations.For more detail see: methodology (https://www.philadelphiafed.org/-/media/frbp/assets/surveys-and-data/y14/y-14-data-methodology).

The 90th percentile original loan-to-value (LTV) ratio.
