Gross profit margins were 17.0 percent in the current quarter compared to 17.1 percent in the prior year quarter. The benefits of higher volumes on gross profit margin in the current year quarter were negatively impacted by a less favorable product sales mix, an unfavorable Mexico Peso to U.S. Dollar exchange rate affecting the Company's operations in Mexico, higher expense provisions for our pension plan and for the accrual of bonuses earned under our incentive bonus plans. The Company froze its Defined Benefit Pension Plan for future benefit accruals effective January 1, 2010. Therefore the increase in pension expense during the current year is attributed to a lower discount rate and the corresponding lower expected return on invested assets that are measured at the end of fiscal year 2012. During the current quarter, the Company contributed $1.75 million to its Defined Benefit Pension Trust.
Operating expenses as a percent of net sales in the current quarter decreased to 11.7% from 12.1% in comparison to the prior year quarter. These expenses would have declined further except for increased costs primarily for our pension and incentive bonus plans as discussed above.
The Company is a partner in VAST LLC, a global alliance of companies involved in the design and manufacture of automotive access products. As reported in our prior earnings releases, VAST's operations in China incurred relocation costs associated with moves to a new facility and start-up costs associated with a new product line. The facility move has been completed but we anticipate these start-up costs and losses to continue over the remaining current fiscal year.
