The monthly imprest level is the liquidity requirement of a country office to be funded by Treasury. It is the cash needed by country offices to fund their operations monthly. The imprest level is also a cash management tool used by Treasury to promote efficient cash management. The sum of all imprest levels provides a good estimate of cash outflows from country offices and is used to estimate UNDP’S liquidity needs.
Source: Management of Zero-Balance Account System
A Cash Management tool that consolidates balances from multiple bank accounts (sub-accounts) used for both collections and disbursements into a single master account daily. During nightly posting of transactions, either excess funds are swept from the sub-accounts to the master account or funds are swept from the master to the sub-accounts to restore all sub-accounts to a zero balance. This action is undertaken by the bank with which the ZBA is held.
