The retention escrow is associated with the Senn Delaney acquisition and was paid to certain key executives of Senn Delaney in January 2016 for remaining with the Company for three years subsequent to the acquisition (See Note 8, Acquisitions). The Company has lease agreements and business licenses with terms that require the Company to restrict cash through the termination dates of the agreements, which extend through 2018. Non-current restricted cash is included in Other non-current assets on the Consolidated Balance Sheet.
