Fair Value Disclosures [Abstract]
Disclosures about the Fair Value of Financial Instruments	Disclosures about the Fair Value of Financial Instruments As of December 31, 2014 and 2013, Wave's financial assets that are measured at fair value on a recurring basis are comprised of overnight money market fund investments. Wave invests excess cash from its operating cash accounts in overnight money market funds and reflects these amounts (approximately $1,188,000 and $1,417,000 at December 31, 2014 and 2013, respectively) within cash and cash equivalents on the consolidated balance sheet using quoted prices in active markets for identical assets (Level 1). Financial instruments not measured or recorded at fair value consist of accounts receivable, collateralized receivables, accounts payable and secured borrowings. The estimated fair value of accounts receivable, collateralized receivables, accounts payable and secured borrowings approximates their carrying value. Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates.
