SOLUTION
Seasoning is the amount of time that has passed or has been covered since a debt security has been issued. More seasoned means more time has been passed and it is approaching maturity.
Why WAM will go down?
As it becomes more seasoned, weighted average maturity in pool of fixed rate fully amortizing loans will reduce since less years are remaining till maturity.
Why WAL will go down?
Weighted average life (WAL) is the average time period that amount of unpaid principal on a pool of loans remains outstanding. It shows how many years it will take to receive amount of the outstanding principal. Example: if the major portion of the repayment of principal is in 5 years, the WAL will be closer to 5 years. This will reduce as the mortgages become more seasoned.
Why WAC will remain the same?
