Agency Mortgage-Backed Security (MBS) A type of Mortgage-Backed Security backed by government guaranteed mortgage loans.

Asset Management Estate (AME)
Estate that holds the assets of a failed institution. Commonly administered by NCUA's Asset Management and Assistance Center, to which the NCUA Board has delegated statutory authorities providing broad supervisory and management powers over the credit union's assets and operations.

Excess Spread ​The extent to which the Weighted Average Coupon on the assets underlying an asset-backed security exceeds the coupon rate of that security plus any relevant fees (i.e. servicing, administration, trustee, etc...). Since multiple securities can be issued from the same trust, this measure is security specific.
​​Foreclosure ​The legal proceedings initiated by a creditor to repossess the collateral for a loan that is in default, usually with the intent to liquidate the seized assets in an auction.
​​Home Price Appreciation (HPA) ​The rate by which house prices increase (or decrease) for a specified area, usually quoted on an annual basis.

​Legacy Assets ​The Legacy Assets are a portfolio of debt securities held by the Asset Management Estates (AMEs) of failed corporate credit unions.  Legacy Assets include those assets that were securitized through the NCUA Guaranteed Note (NGN) Program in late 2010 and early 2011, assets that were retained by the AMEs, and assets that were sold outright in late 2010 and early 2011.
Legacy Assets primarily consists of:
  • Private label, residential mortgage-backed securities (Non-Agency RMBS);

  • Corporate bonds.
Liquidation ​The process through which the assets backing a defaulted loan are sold for cash.
Loan-to-Value (LTV) ​The ratio of the outstanding principal amount of a mortgage loan to the appraised value of the mortgaged property.

Market Price ​The price at which a security trades (i.e. could be purchased or sold) in the secondary market.
Maturity Date ​The date as of which the principal of and interest on a security become due and payable.
​Medium Term Notes (MTNs) ​Notes issued in the capital markets in late 2009 by US Central Federal Credit Union and Western Corporate Federal Credit Union.  The MTNs were issued to fund the corporate credit unions' repayment of their loans from the Credit Union System Investment Program (CUSIP).  The MTNs were issued under the Temporary Corporate Credit Union Loan Guaranty Program and are comprised of two and three year maturities.
Mortgage-Backed Security(MBS) ​A mortgage‐backed security (MBS) is an asset‐backed security or debt obligation that represents a claim on the cash flows from mortgage loans, most commonly on residential property.  First, mortgage loans are purchased from banks, mortgage companies, and other originators.  Then, these loans are assembled into pools.  This is done by government agencies, government‐sponsored enterprises, and private entities, which may offer features to mitigate the risk of default associated with these mortgages.  Mortgage-backed securities represent claims on the principal and payments on the loans in the pool, through a process known as securitization.

Overcollateralization ​The amount, if any, by which the aggregate outstanding principal balance of collateral exceeds the aggregate outstanding principal balance of the securities backed by such collateral. Overcollateralization is used as a form of Credit Enhancement in certain asset- and mortgage-backed security transactions.

Segregating the costs into one fund improves the transparency of NCUA's stabilization actions and allows natural person credit unions to pay for the costs of stabilizing the corporate credit union system over time.
​​Tranche ​One of several related securities issued in a Securitization transaction. Tranches in the same transaction may have different maturity, subordination and interest rate characteristics, and may represent a different slice of the transaction's risk.  Transaction documentation may define the tranches as different "classes" of securities, each identified by a letter (e.g. the Class A, Class B, or Class C securities) and each tranche may have a different credit rating.
