The tables also include a reconciliation of the disaggregated revenue within our reportable segments. ​

(b) | Remaining Performance Obligations
Remaining performance obligations represent the aggregate transaction price allocated to performance obligations which are fully or partially unsatisfied at the end of the period. Remaining performance obligations include noncancelable purchase orders and other long-term contracts. At September 30, 2023, we had approximately $360 million in remaining performance obligations for contracts with an original duration of greater than one year which we expect approximately 80% to be recognized as revenues in the next twenty-four months and approximately 20% thereafter.
(c) | Contract assets, contract liabilities and accounts receivable
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, 2023, our contract assets, contract liabilities and accounts receivable totaled $138.6 million, $123.1 million and $198.6 million, respectively. At September 30, 2022, our contract assets, contract liabilities and accounts receivable totaled $125.2 million, $137.6 million and $164.6 million, respectively. At September 30, 2021, our contract assets, contract liabilities and accounts receivable totaled $93.8 million, $108.8 million and $146.3 million, respectively. During 2023, we recognized approximately $80 million in revenues that were included in the contract liabilities balance at September 30, 2022.
