Subsequent Events	Subsequent Events GoMedigap Acquisition On January 22, 2018, we completed our acquisition of all outstanding membership interests of Wealth, Health and Life Advisors, LLC, more commonly known as GoMedigap, a technology-enabled provider of Medicare Supplement enrollment services. The acquisition price primarily consisted of cash of $15.0 million, less $0.1 million cash acquired, and approximately 294,637 shares of our common stock. In addition, we are obligated to pay an additional $20 million in cash and 589,275 shares of our common stock, subject to the terms of the acquisition agreement and upon final determination of the achievement of certain milestones in 2018 and 2019. Restructuring Activities On February 25, 2018, our Board of Directors approved a plan to close our sales call center in Massachusetts and to terminate the employment of other employees in other locations. As part of this plan, we expect to eliminate approximately 110 full-time positions, representing approximately 10% of our workforce, primarily within customer care and enrollment. We expect to incur approximately $2.0 million to $2.4 million for employee termination benefits and related costs as well as approximately $0.3 million to $0.5 million in contract termination and other restructuring charges. Substantially all of the restructuring charges are expected to result in cash expenditures. These restructuring charges were recorded in the first half of 2018, when the activities comprising the plan were completed.

The commitments under the Credit Agreement expire on September 17, 2021.
