16. | Pension Plans
The Company and certain subsidiaries have contributory and non-contributory pension plans covering substantially all of their employees. Those contributory funded pension plans include defined benefit pension plans and defined contribution pension plans. Under the plans, employees are entitled to lump-sum payments at the time of termination of their employment or pension payments. Defined benefit pension plans consist of a plan of which the amounts of such payments are determined on the basis of length of service and remuneration at the time of termination and a cash balance plan. The Company and certain subsidiaries’ funding policy is to contribute annually the amounts actuarially determined. Assets of the plans are invested primarily in debt securities and marketable equity securities. Net periodic pension cost for the six months ended September 30, 2022 and 2023 consists of the following:
