Contract Assets and Contract Liabilities

Contract assets are recorded when the Company's right to consideration is conditional on constraints other than the passage of time. The Company had no material contract assets as of March 31, 2021 and December 31, 2020.

Contract liabilities include advance payments and billings in excess of revenue recognized, which are primarily related to advanced billings for service type warranty. Contract liabilities are presented under deferred revenues. The Company's deferred revenues as of March 31, 2021 and December 31, 2020 were as follows:

		March 31,	December 31,
		2021	2020

Revenue recognized in 2021 that was included in deferred revenue balance as of December 31, 2020 was $18.4 million for the three months ended March 31, 2021.

Remaining Performance Obligations

Remaining Performance Obligations (“RPO“) represent contracted revenue that has not yet been recognized, which includes deferred revenue and amounts that will be invoiced and recognized as revenue in future periods. As of March 31, 2021, the total RPO amounted to $89.7 million. The Company expects to recognize $74.9 million of this RPO during the next 12 months, $9.2 million over the subsequent 12 months and the remaining $5.6 million thereafter.

Incremental Costs of Obtaining a Contract

Sales commissions earned mainly by the Company’s sales agents are considered incremental costs of obtaining a contract with a customer, as the Company expects the benefit of those commissions to be longer than one year. The majority of the sales commissions are not subject to capitalization, as the commission expense is recognized as the related revenue is recognized. Sales commissions for initial contracts related to the service type warranty are deferred and then amortized on a straight-line basis over the expected customer relationship period if the Company expects to recover those costs. Amortization expense is included in selling, general and administrative expenses in the consolidated statements of operations. As of March 31, 2021 and December 31, 2020, the deferred commissions amounted to $5.3 million and $5.0 million, respectively.
