(b) | Remaining Performance Obligations
Our remaining performance obligations, which is the equivalent of our backlog, represent the expected transaction price allocated to our contracts that we expect to recognize as revenue in future periods when we perform under the contracts. These remaining obligations include amounts that have been formally appropriated under contracts with the U.S. Government, and exclude unexercised contract options and potential orders under ordering-type contracts such as Indefinite Delivery, Indefinite Quantity contracts. At September 30, 2021, we had $592 million in remaining performance obligations of which we expect to recognize revenues of 75% in the next twelve months.
(c) | Contract assets and contract liabilities
We report assets and liabilities related to our contracts with customers on a contract-by-contract basis at the end of each reporting period. At September 30, 2021, our contract assets and contract liabilities totaled $93.8 million and $108.8 million, respectively. During 2021, we recognized approximately $82 million in revenues that were included in the contract liabilities balance at September 30, 2020.
