Effects

Amortization associated with debt has two main effects:

Credit risk First and many importantly, it substantially decreases the credit
risk from the loan or bond. Inside a bullet loan (or topic bond), the bulk associated with
the credit risk is within the repayment of the main at maturity, at
which point your debt must either be repaid in full or folded over. By
paying from the principal over time, this particular risk is mitigated.
Rate of interest risk A secondary impact is that amortization decreases the
duration of your debt, reducing the debt's sensitivity to rate of interest
risk, as compared to debt using the same maturity and discount rate. This is
because there are smaller payments later on, so the weighted-average
maturity from the cash flows is reduce.

Weighted-average life



The number weighted average from the times of the principal repayments of the
amortizing loan is known as the weighted-average life (WAL), additionally
called "average life". It is the average time until the dollar of principal is actually
repaid.

In a method,

WAL = S_i=1 ^n \frac P_i P t_i,

exactly where:

- P is the main,
- P_i is the main repayment in coupon we, hence
- \fracP_i P is the fraction from the principal repaid in discount i, and
- t_i is the time from the beginning to coupon i.
