Contract Balances

The Company has contract assets consisting of Customer receivables in the Consolidated Balance Sheets which represent the amount of consideration the Company expects to be entitled to in exchange for the goods or services rendered to its customers.

When the Company receives deposits, the recognition of revenue is deferred and results in the recognition of a contract liability (Customer deposits) presented as a component of Other Current Liabilities in the Consolidated Balance Sheets. Subsequent recognition of revenue and the satisfaction of the contract liability is typically less than one year as the Company’s standard contract is less than one year. As of December 31, 2018 and December 31, 2017, the contract liability related to customer deposits was $37.7 million and $30.5 million, respectively. The Company recognized revenues that were included in the contract liability at the beginning of the current year of $30.5 million. In addition, the Company assumed a contract liability of $1.5 million related to a business combination during the year.
