Note 19. Retirement benefits

Woodward provides various retirement benefits to eligible members of the Company, including contributions to various defined contribution plans, pension benefits associated with defined benefit plans, postretirement medical benefits and postretirement life insurance benefits. Eligibility requirements and benefit levels vary depending on employee location.

Defined contribution plans

Most of the Company’s U.S. employees are eligible to participate in the U.S. defined contribution plan. The U.S. defined contribution plan allows employees to defer part of their annual income for income tax purposes into their personal 401(k) accounts. The Company makes matching contributions to eligible employee accounts, which are also deferred for employee personal income tax purposes. Certain foreign employees are also eligible to participate in similar foreign plans.

Most of Woodward’s U.S. employees with at least two years of service receive an annual contribution of Woodward stock, equal to 5% of their eligible prior year wages, to their personal Woodward Retirement Savings Plan accounts. Woodward fulfilled its annual Woodward stock contribution obligation using shares held in treasury stock by issuing a total of 202 shares of common stock for a value of $14,741 in the second quarter of fiscal year 2018, and 199 total shares of common stock for a value of $14,014 in the second quarter of fiscal year 2017.

The amount of expense associated with defined contribution plans was as follows:



	Three-Months Ended				Nine-Months Ended
	June 30,				June 30,
	2018		2017		2018		2017
Company costs	$	8,262	$	8,039	$	24,858	$	23,790

Defined benefit plans

Woodward has defined benefit plans that provide pension benefits for certain retired employees in the United States, the United Kingdom, Japan and, as a result of the acquisition of L’Orange, Germany. Woodward also provides other postretirement benefits to its employees including postretirement medical benefits and life insurance benefits. Postretirement medical benefits are provided to certain current and retired employees and their covered dependents and beneficiaries in the United States and the United Kingdom. Life insurance benefits are provided to certain retirees in the United States under frozen plans, which are no longer available to current employees. A September 30 measurement date is utilized to value plan assets and obligations for all of Woodward’s defined benefit pension and other postretirement benefit plans.

In connection with the acquisition of L’Orange on June 1, 2018, Woodward assumed the unfunded defined benefit pension obligations of the L’Orange defined benefit pension plans (the “L’Orange Pension Plans”). Woodward’s assumption of the liability associated with the L’Orange Pension Plans was part of the total consideration paid by Woodward to acquire L’Orange and thus reduced Woodward’s cash payment for the transaction. Woodward has completed its valuation of the defined benefit pension obligations associated with the L’Orange Pension Plans and determined the value of the associated unfunded obligation was $38,998, of which $1,143 was considered current as of the June 1, 2018 acquisition date. The L’Orange Pension Plans had expenses of $168 and Woodward made $54 of contributions to the L’Orange Pension Plans during the three and nine-months ended June 30, 2018. Similar to Woodward’s other defined benefit plans and other postretirement benefit plans, a September 30 measurement date will be utilized to value the plan obligations of the L’Orange Pension Plans going forward. The L’Orange Pension Plans are unfunded.

U.S. GAAP requires that, for obligations outstanding as of September 30, 2017, the funded status reported in interim periods shall be the same asset or liability recognized in the previous year end statement of financial position adjusted for (a) subsequent accruals of net periodic benefit cost that exclude the amortization of amounts previously recognized in other comprehensive income (for example, subsequent accruals of service cost, interest cost, and return on plan assets) and (b) contributions to a funded plan or benefit payments.

During the third quarter of fiscal year 2016, Woodward opened a lump-sum buy-out window, which closed in the fourth quarter of fiscal year 2016 and was fully settled during the first quarter of fiscal year 2017, for certain former U.S. employees and/or their dependents eligible to receive postretirement defined benefit pension payments for past employment services to the Company. Eligible pension plan participants were provided the opportunity to elect to receive a one-time lump-sum payment or an immediate annuity in lieu of future pension benefit payments. Pension benefit payments paid from available pension plan assets under the lump-sum buy-out options were $670 during the first nine months of fiscal year 2017. Woodward made no further pension benefit payments under the lump-sum buy-out options.

The amount of cash contributions made to these plans in any year is dependent upon a number of factors, including minimum funding requirements in the jurisdictions in which Woodward operates and arrangements made with trustees of certain foreign plans. As a result, the actual funding in fiscal year 2018 may differ from the current estimate. Woodward estimates its remaining cash contributions in fiscal year 2018 will be as follows:
