Sevcon contributed $10,000 to its U.S. pension plan in the nine months ended July 2, 2011; it presently anticipates contributing a further $46,000 to fund its U.S. plan in the remainder of 2011. In addition, employer contributions to the U.K. defined benefit plan were $426,000 in the first nine months and are estimated to total $505,000 in 2011.

In the second quarter of 2011, the Company changed the inflation index used to calculate the annual increase in accrued benefits for deferred pension plan members of the U.K. defined benefit pension plan. The change in inflation index was from the Retail Prices Index (“RPI”) to the Consumer Prices Index (“CPI”). Deferred pension plan members are current or former employees of the Company who have left the pension plan, retaining a right to future pension benefits, but not having yet brought those benefits into payment. The change of inflation index was for this one class of pension plan member only. As a result of this change, the Company recorded a one-time decrease in the liability for pension benefits of $806,000, net of a tax benefit. This decrease was recorded in the second quarter of 2011 through other comprehensive loss as a reduction to remaining prior service costs of $212,000 and the remaining $594,000 is being amortized as a component of net period benefit costs over 34 years, this being the estimated life expectancy of the deferred members of the U.K. pension plan.
