The nature of the Company’s performance obligations within our Treatment and Services Segments result in the recognition of our revenue primarily over time. The following tables present further disaggregation of our revenues by different categories for our Services and Treatment Segments:

Contract Balances

 

The Company’s contract liabilities consist of deferred revenues which represent advance payment from customers in advance of the completion of our performance obligation. The following table represents changes in our contract liabilities balances:

 

           Year-to-date   Year-to-date 
(In thousands)  June 30, 2022   December 31, 2021   Change ($)   Change (%) 
Contract liabilities                    
Deferred revenue  $3,574   $5,580   $(2,006)   (35.9)%

 

The decrease was attributed primarily due to revenue recognized in connection with a Services Segment contract.

 

During the three and six months ended June 30, 2022, the Company recognized revenue of $2,123,000 and $5,644,000, respectively, related to untreated waste that was in the Company’s control as of the beginning of each respective year. During the three and six months ended June 30, 2021, the Company recognized revenue of $1,763,000 and $6,074,000, respectively, related to untreated waste that was in the Company’s control as of the beginning of each respective year. Revenue recognized in each period related to performance obligations satisfied within the respective period.

 

 

Remaining Performance Obligations

 

The Company applies the practical expedient in paragraph 606-10-50-14 and does not disclose information about remaining performance obligations that have original expected durations of one year or less.

 

Within our Services Segment, there are service contracts which provide that the Company has a right to consideration from a customer in an amount that corresponds directly with the value to the customer of our performance completed to date. For those contracts, the Company has utilized the practical expedient in ASC 606-10-55-18, which allows the Company to recognize revenue in the amount for which we have the right to invoice; accordingly, the Company does not disclose the value of remaining performance obligations for those contracts.

 

The Company’s contracts and subcontracts relating to activities at governmental sites generally allow for termination for convenience at any time at the government’s option without payment of a substantial penalty. The Company does not disclose remaining performance obligations on these contracts.
