Investments in Federal securities include non-marketable par value Treasury securities, market-based Treasury securities, marketable Treasury securities, and securities issued by other Federal entities.  Non-Federal securities include those issued by state and local governments, Government-sponsored enterprises, and other private corporations. 

Marketable Federal securities can be bought and sold on the open market.  Non-marketable par value Treasury securities are issued by the Bureau of Public Debt to Federal accounts and are purchased and redeemed at par exclusively through Treasury's Federal Investment Branch.  Non-marketable market-based Treasury securities are also issued by the Bureau of Public Debt to Federal accounts. They are not traded on any securities exchange but mirror the prices of particular Treasury securities trading in the Government securities market.  Amortization is done using the interest or straight-line method.
