# Managers

### Buy longZCB

Managers can buy `longZCB` of an instrument if they are bullish on an instrument. They can simulate how much returns longZCB will generate, given how much the underlying instrument will generate. 

### Redeem longZCB

They can later redeem `longZCB`. For the creditline, they will redeem it at maturity. For the lending pool, they can redeem it whenever they want to realize profit or offload risk from the lending pool.
