Constitution was a mid-tier corporate credit union within a three-tiered structure of
the Nation‟s credit union system. The mid-tier corporate credit unions provide
liquidity, as well as a range of transactional products and services to the bottom tier,
which consists of the NPCUs. The NPCUs invest their excess funds in a corporate
credit union. The invested funds are drawn down to meet increasing liquidity
demands due to member loan demand and share withdrawals.
