At March 31, 2020, the unrecognized compensation cost related to unvested stock options and awards was $22.4 million. The weighted average period over which these awards will vest is approximately 3.4 years. 2012 Equity Incentive Plan The Company’s Second Amended and Restated 2012 Equity Incentive Plan (the “Plan”) provides that current or prospective officers, employees, non-employee directors and advisors can receive share-based awards such as stock options, restricted stock, restricted stock units and other stock awards. The Plan seeks to promote the highest level of performance by providing an economic interest in the long-term success of the Company. As of March 31, 2020, 3.1 million shares of common stock were reserved for issuance under the Plan, including 0.3 million shares available for future grant. No stock award will have a term in excess of 10 years. All awards granted under the Plan become vested and exercisable ratably over a five year period on each yearly anniversary of the grant date. The Nominating, Compensation and Stock Option Committee of the Board of Directors is responsible for determining the terms of the grants in accordance with the Plan.

Annual offerings commence and terminate on the respective year’s first and last calendar day. Under the ESPP, the Company is authorized to issue up to 4.1 million shares of its common stock to its employees. Pursuant to such authorization, there are 2.1 million shares available for future grant at March 31, 2020.

Deferred Compensation Plan The Company offers a Supplemental Executive Retirement Plan (“SERP”) for executives and certain key employees. The SERP allows participants to defer a portion of their earned income on a pre-tax basis and as of the last day of each plan year, each participant will be credited with a match of a portion of their deferral in the form of the Company’s common stock based on the then-current market value. Under the SERP, the Company is authorized to issue 1.0 million shares of its common stock to its employees. Pursuant to such authorization, the Company has 0.4 million shares available for future grant at March 31, 2020. At the time of issuance, such shares are accounted for at cost as treasury stock.
