How Average Life Sensitivity works
In practice, the result depends on the transaction documents, collateral performance, payment priority and the triggers that can redirect cash flows. For Average Life Sensitivity, investors usually model both the expected path of cash flows and adverse scenarios that change payment timing or loss allocation.
Why it matters in markets
Average Life Sensitivity matters because securitized cash flows are path-dependent. Prepayments, defaults, recoveries, servicing actions and structural triggers can change duration and principal return even when the collateral pool initially looks similar.
How to interpret Average Life Sensitivity
Interpret Average Life Sensitivity through the transaction waterfall and collateral assumptions. Check which class absorbs losses first, which triggers redirect cash, how quickly principal can return and whether servicing or prepayment behavior changes the expected path.
Limits and context
Average Life Sensitivity can vary materially across deals. Prospectuses, pooling and servicing agreements, indentures and trustee reports determine the actual mechanics; generic market definitions should not replace transaction-level analysis.
