Asset-backed commercial paper (ABCP) is a form of commercial paper that is collateralised by financial assets. ABCP is a short-term instrument with an initial maturity of between 1 and 360 days (usually around 30 days). It is issued from an asset-backed commercial paper programme, also known as a conduit.


An asset-backed security (ABS) is a security the income payments and therefore value of which derived from and collateralised by (or "backed" by) a specified pool of underlying assets. Pooling the assets into financial instruments allows them to be sold to general investors, a process called securitisation. This process allows the risk of investing in the underlying assets to be stratified as each security will represent a portion of the total value of the diverse pool of underlying assets. The different instruments ussed from a vehilce represent differing levels of risk, as they represent differnet priorities of payment. The pools of underlying assets can include payments from credit cards, auto loans, and mortgage loans, or more esoteric cash flows such as payments from aircraft leases, royalty payments and movie revenues.

Floating rate notes (FRNs) are bonds that have a variable coupon, equal to a money market reference rate, such as LIBOR or federal funds rate, plus a quoted spread (a.k.a. quoted margin). The spread is a rate that remains constant. Almost all FRNs have quarterly coupons, i.e. they pay out interest every three months. At the beginning of each coupon period, the coupon is calculated by taking the fixing of the reference rate for that day and adding the spread.

The London Interbank Bid Rate (LIBID) is a bid rate; the rate bid by banks on deposits (i.e., the rate at which a bank is willing to borrow from other banks). It is "the opposite" of the LIBOR (an offered, hence "ask" rate, the rate at which a bank will lend).  Conventional wisdom used to assert that a LIBID rate could be calculated by subtracting a fixed amount (often given as 1/8 th of 1%) from the prevailing LIBOR rate, however this is no longer the case as bid/offer spreads have tightened in recent years.

The party that originally buys the securities effectively acts as a lender. The original seller is effectively acting as a borrower, using their security as collateral for a secured cash loan at a fixed rate of interest.
