| (DF). | | RMBS are the largest proportion of the European ABS (Asset Backed Securities) market. |
|
| |
|
| The number less than one which we multiply a single future cash flow by, to work out its present value as:
| |
|
| |
| PV = DF x future cashflow.
| |
|
| |
|
| |
| The periodic discount factor is calculated from the periodic [[yield]] as:
| |
|
| |
| DF = (1 + periodic yield)<SUP>-n</SUP>
| |
|
| |
|
| |
| Commonly abbreviated as DF(n,r) ''or'' DF<SUB>n,r</SUB>
| |
|
| |
| Where:
| |
|
| |
| n = number of periods.
| |
|
| |
| r = periodic yield (or periodic cost of capital).
