(A) Plan information is publicly available for the Local 641 Pension fund. The Form 5500 indicates that the Plan is currently underfunded. Future contributions have increased pursuant to the collective bargaining agreement (dated January 31, 2011 and expiring on January 31, 2014) and the updated Rehabilitation Plan (dated February 17, 2011). Per the terms of the Rehabilitation Plan, required contributions will increase by approximately 4% (annually) through 2018.
(B) The Company also contributes to a Swedish pension plan that supplements the Swedish social insurance system. The pension plan guarantees employees a pension based on a percentage of their salary and also represents a multi-employer pension plan, however the pension plan was not significant in any year presented. This pension plan is not underfunded.
