Employee Pension Plans

NOTE J — Employee Pension Plans

The following table summarizes the components of net periodic pension cost for our defined benefit plans for the periods indicated:

	Three Months Ended						Nine Months Ended
(in thousands)	February 29, 2012			February 28, 2011			February 29, 2012			February 28, 2011
Defined benefit plans:
Service cost	$	65		$	238		$	198		$	711
Interest cost		376			358			1,132			1,070
Expected return on plan assets		(408	)		(333	)		(1,222	)		(999	)
Net amortization and deferral		43			64			129			192
Net pension cost of defined benefit plans	$	76		$	327		$	237		$	974

The decrease in net pension cost during the three and nine months ended February 29, 2012 over the comparable period of fiscal 2011 was driven by the curtailment of The Gerstenslager Company Bargain Unit Employees' Pension Plan during the fourth quarter of fiscal 2011, as disclosed in "Part II — Item 8. — Financial Statements and Supplementary Data — Note J — Employee Pension Plans" of our 2011 Form 10-K.

We anticipate total contributions of approximately $1,227,000 in fiscal 2012, of which approximately $981,000 had been made as of February 29, 2012.
