Note 5. Revenue from Contracts with Customers 

The Company recognizes revenue when it transfers promised services to customers in an amount that reflects the consideration to which it expects to be entitled in exchange for those services.

The following table presents the Company’s revenues disaggregated into categories based on the nature of such revenues (in thousands):

Contract balances:

Contract assets consist of costs and estimated earnings in excess of billings on uncompleted engineering contracts. The balance was entirely from the ESS Metron acquisition, and was $15.1 million and $9.9 million as of September 30, 2022 and December 31, 2021, respectively.

The Company’s contract liabilities primarily relate to upfront payments and consideration received from customers for Data Center Hosting, billings in excess of costs and estimated earnings on uncompleted Engineering contracts and the upfront license fee generated from our legacy animal health business. The table below presents changes in the total deferred revenue liability and billings in excess of costs and estimated earnings.

Beginning balance - January 1, 2022   $ 27,903  
Revenue recognized     (1,720 )
Billings in excess of costs and estimated earnings     5,965  
Ending balance - September 30, 2022   $ 32,148  

Transaction price allocated to remaining performance obligations:

Remaining performance obligations represent the transaction price of contracts for work that has not yet been performed. Amounts related to Bitcoin mining are not included because the Company elected the practical expedient to not disclose amounts related to contracts with a duration of one year or less.

Additionally, we have elected to use the practical expedient to not adjust the transaction price for the existence of a significant financing component if the timing difference between a customer’s payment and our performance is one year or less.
