Time bins
From ACT Wiki
Risk management.
Intervals of time to repricing or final maturity.
In determining the interest rate risk associated with holding financial assets/liabilities it is necessary to determine the proportion of the total investment whose return/cost can be repriced at specific time intervals.
Thus a floating rate instrument whose rate is reset every 6 months will be in the 6-month time bin.
In relation to liquidity risk, the final maturity is relevant.
Time bins are also known as time buckets.
