Benefit Plans

We provide defined benefit pension plans for certain current and former manufacturing and plant administrative personnel throughout the world as determined by collective bargaining agreements or employee benefit standards set at the time of acquisition of certain businesses. In addition to providing pension benefits to certain employees, we sponsor an unfunded postretirement welfare benefits plan for two groups of United States employees, including the same employees who receive pension benefits under the United States defined benefit pension plan. Benefits under this plan include retiree life insurance and retiree medical coverage, including prescription drug coverage. Additional information regarding our defined benefit pension plans and other postretirement benefits plan is included in our consolidated financial statements included in our Annual Report on Form 10-K for the year ended March 31, 2012, dated May 29, 2012.

We contribute amounts to the defined benefit pension plans at least sufficient to meet the minimum requirements as stated in applicable employee benefit laws and local tax laws. We record liabilities for the difference between the fair value of the plan assets and the benefit obligation (the projected benefit obligation for pension plans and the accumulated postretirement benefit obligation for other postretirement benefits plans) on our accompanying Consolidated Balance Sheets.
