[1] On an annual basis, the Company reviews and modifies the representative peer group based on changes to the Company's business and changes to the businesses of the companies within the peer group. The decrease in expected volatility, as compared to 2013, is primarily driven by the addition or removal of certain companies in the representative peer group to ensure that the peer group is representative of the Company's current operations.
