​ Contract balances (in thousands) The following table provides information about receivables, contract assets and contract liabilities from contracts with customers. ​

Contract Liabilities (Deferred Revenue current and non-current) | ​ | $ | 63,742 | ​ | $ | 55,147
​ Contract assets relate primarily to multi-year term license arrangements and the remaining contractual billings. These contract assets are transferred to receivables when the right to billing occurs, which is normally over 1-5 years. The contract liabilities primarily relate to the advance consideration received from customers for subscription and maintenance services. Revenue is recognized for these services over time. As a practical expedient, we do not adjust the promised amount of consideration for the effects of a significant financing component when we expect, at contract inception, that the period between our transfer of a promised product or service to a customer and when the customer pays for that product or service will be one year or less. We do not typically include extended payment terms in our contracts with customers. Revenue recognized during the year ended December 31, 2021 included $41.3 million that was included on the December 31, 2020 balance sheet in contract liabilities. Deferred revenue increased in the same period due to timing of annual renewals. Transaction price allocated to the remaining performance obligations The following table includes estimated revenue expected to be recognized in the future related to performance obligations that are unsatisfied (or partially unsatisfied) at the end of the reporting period. ​

​ The Company applies practical expedients and does not disclose information about remaining performance obligations (a) that have original expected durations of one year or less, or (b) where revenue is recognized as invoiced. Costs of obtaining a contract The Company incurs incremental costs related to commissions, which can be directly tied to obtaining a contract. Under Topic 606, the Company capitalizes commissions associated with certain new contracts and amortizes the costs over a period of benefit based on the transfer of goods or services that we have determined to be up to seven years. We determined the period of benefit by taking into consideration our customer contracts, our technology and other factors, including customer attrition. Commissions and amortization expense are included in Sales and Marketing expenses on the consolidated statements of operations. Applying the practical expedient, the Company recognizes the incremental costs of obtaining contracts as an expense when incurred if the amortization period for the assets that the Company otherwise would have recognized is one year or less. These costs are included in Sales and Marketing expense in the consolidated statements of operations. The following tables provide information related to the capitalized costs and amortization recognized in the current and prior period: ​
