# Renewable Liquidity

At maturity:

* If $$({PT}\_c \geq {YT}\_c)$$, excess BT  $$({PT}\_c - {YT}\_c)$$ will be transferred to the maturity pool.
* If $$({PT}\_c < {YT}\_c)$$, deficit BT  $$({YT}\_c - {PT}\_c)$$ will be replenished from the BT vault pool

LP Shares remain valid indefinitely. Upon renewal, new PT and YT tokens are issued, and the vPT will map to the new PT. The vPT pool resets to a 1:1 ratio with BT.
