How to read USAspending.gov award record

The obligated amount is money the government has legally committed to pay and has set aside in its accounts. The ceiling, which USAspending calls the potential value, is the most the contract could be worth if every option is exercised and every possible order is placed. The ceiling is a limit, not a payment, and it is often many times the obligated amount.
