Revenue from Contract with Customer [Abstract]  
The Company's contracts related to transportation and distribution revenue are primarily comprised of a mix of natural gas supply, transportation and distribution performance obligations, as well as limited performance obligations related to system maintenance and improvement. Based on the nature of the agreements, revenue for all but one of the Company's natural gas supply, transportation and distribution performance obligations is recognized on a right to invoice basis as the performance obligations are met, which represents what the Company expects to receive in consideration and is representative of value delivered to the customer. System maintenance and improvement contracts are specific and tailored to the customer's needs, have no alternative use and have an enforceable right to payment as the services are provided. Revenue is recognized on an input method, based on the actual cost of service as a measure of the performance obligation satisfaction. Differences between amounts invoiced and revenue recognized under the input method are reflected as an asset or liability on the Consolidated Balance Sheets. The costs of system improvement projects are recognized as a financing arrangement in accordance with guidance in the lease standard while the margin is recognized in accordance with the revenue standard as discussed above.
The Company has a contract with Spire that has fixed pricing which varies over the contract term. For this specific contract, the transaction price has been allocated ratably over the contractual performance obligation. Based on a downward revision of the rate during the Company's long-term natural gas transportation contract with Spire, ASC 606 requires the Company to record the contractual transaction price, and therefore aggregate revenue, from the contract ratably over the term of the contract. Following the November 2018 rate decline, recognized performance obligations exceeded amounts invoiced and the contract liability began to decline at a rate of approximately $138 thousand per quarter and will continue to decline at the same rate through the end of the contract in October 2030. As of September 30, 2020, the revenue allocated to the remaining performance obligation under this contract is approximately $54.1 million.
During the fourth quarter of 2020, MoGas entered into a new long-term firm transportation services agreement with Spire, its largest customer. Upon completion of the STL interconnect project as described in Note 7 ("Property And Equipment"), the agreement will increase Spire’s firm capacity from 62,800 dekatherms per day to 145,600 dekatherms per day through October 2030 and replace the previous firm transportation agreement. In accordance with ASC 606, the Company will account for the contract modification in the fourth quarter of 2020 as a termination of the existing transportation contract and a creation of a new transportation contract with Spire that will be accounted for prospectively.
The table below summarizes the Company's contract liability balance related to its transportation and distribution revenue contracts as of September 30, 2020:
