“Loans,” “mortgage loans” and “mortgages” refer to both whole loans and loan participations, secured by
residential real estate, cooperative shares or by manufactured housing units.
“Loan-to-value ratio” or “LTV ratio” refers to the ratio, at any point in time, of the unpaid principal amount
of a borrower’s mortgage loan to the value of the property that serves as collateral for the loan (expressed as a
percentage).
“Minimum capital requirement” refers to the amount of core capital below which we would be classified by
OFHEO as undercapitalized. Our minimum capital requirement is generally equal to the sum of: (1) 2.50% of
on-balance sheet assets; (2) 0.45% of the unpaid principal balance of outstanding Fannie Mae MBS held by
third parties; and (3) up to 0.45% of other off-balance sheet obligations.
“Mortgage assets,” when referring to our assets, refers to both mortgage loans and mortgage-related securities
we hold in our investment portfolio.
“Mortgage credit book of business” refers to the sum of the unpaid principal balance of: (1) mortgage loans
held in our mortgage portfolio; (2) Fannie Mae MBS held in our mortgage portfolio; (3) non-Fannie Mae
mortgage-related securities held in our investment portfolio; (4) Fannie Mae MBS held by third parties; and
(5) other credit enhancements that we provide on mortgage assets.
“Mortgage-related securities” or “mortgage-backed securities” refer generally to securities that represent
beneficial interests in pools of mortgage loans or other mortgage-related securities. These securities may be
issued by Fannie Mae or by others.
“Multi-class Fannie Mae MBS” refers to Fannie Mae MBS, including REMICs, where the cash flows on the
underlying mortgage assets are divided creating several classes of securities, each of which represents a
beneficial ownership interest in a separate portion of cash flows. By separating the cash flows, the resulting
classes may consist of: (1) interest-only payments; (2) principal-only payments; (3) different portions of the
principal and interest payments; or (4) combinations of each of these. Terms to maturity of some multi-
class Fannie Mae MBS, particularly REMIC classes, may match or be shorter than the maturity of the
underlying mortgage loans and/or mortgage-related securities. As a result, each of the classes in a multi-
class Fannie Mae MBS may have a different coupon rate, average life, repayment sensitivity or final maturity.
“Multifamily guaranty book of business” refers to the sum of the unpaid principal balance of: (1) multifamily
mortgage loans held in our mortgage portfolio; (2) multifamily Fannie Mae MBS held in our mortgage
portfolio; (3) multifamily Fannie Mae MBS held by third parties; and (4) other credit enhancements that we
provide on multifamily mortgage assets. Excludes non-Fannie Mae mortgage-related securities held in our
investment portfolio for which we do not provide a guaranty.
“Multifamily mortgage loan” refers to a mortgage loan secured by a property containing five or more
residential dwelling units.
“Multifamily business volume” refers to the sum in any given period of the unpaid principal balance of: (1) the
multifamily mortgage loans we purchase for our investment portfolio; (2) the multifamily mortgage loans we
securitize into Fannie Mae MBS; and (3) credit enhancements that we provide on our multifamily mortgage
assets.
“Multifamily mortgage credit book of business” refers to the sum of the unpaid principal balance of:
(1) multifamily mortgage loans held in our mortgage portfolio; (2) multifamily Fannie Mae MBS held in our
mortgage portfolio; (3) multifamily non-Fannie Mae mortgage-related securities held in our investment
portfolio; (4) multifamily Fannie Mae MBS held by third parties; and (5) other credit enhancements that we
provide on multifamily mortgage assets.
“Negative-amortizing loan” refers to a mortgage loan that allows the borrower to make monthly payments that
are less than the interest actually accrued for the period. The unpaid interest is added to the principal balance
of the loan, which increases the outstanding loan balance. Negative-amortizing loans are typically adjustable-
rate mortgage loans.
