Employee Savings Plan

In 1993, the Company adopted the provisions of the Regeneron Pharmaceuticals, Inc. 401(k) Savings Plan (the “Savings Plan”). The terms of the Savings Plan provide for employees who have met defined service requirements to participate in the Savings Plan by electing to contribute to the Savings Plan a percentage of their compensation to be set aside to pay their future retirement benefits, as defined. The Savings Plan, as amended and restated, provides for the Company to make discretionary contributions (“Contribution”), as defined. The Company recognized $5.7 million, $6.3 million, and $4.1 million of Contribution expense in 2013, 2012, and 2011, respectively. During the first quarter of 2014, 2013, and 2012, the Company contributed 20,603, 38,248, and 63,937 shares, respectively, of Common Stock to the Savings Plan in satisfaction of the 2013, 2012, and 2011 Contribution, respectively.
