The actuarial loss (gain) arises from differences in estimates and actual experiences for certain assumptions, including changes in the discount rate and expected return on assets. For the quarter ended January 30, 2015, we contributed $10.2 million to our defined benefit employee pension plans, and we expect contributions to be approximately $15.0 million for the full fiscal year.
