[1] During fiscal 2014, the Company amended the SERP to limit the amount of eligible wages under the plan that count toward the SERP benefit for the active participant. As a result, unrecognized prior service cost was reduced by $4.5 million during fiscal 2014.

[2] The projected benefit obligation was included in accrued expenses and other long-term liabilities in the Company’s consolidated balance sheets depending on the expected timing of payments.

[3] The SERP is a non-qualified pension plan and hence the insurance policies are not considered to be plan assets. Accordingly, the table above does not include the insurance policies with cash surrender values of $53.6 million and $51.4 million as of January 31, 2015 and February 1, 2014, respectively.
