Retirement Benefit Plans

RETIREMENT BENEFIT PLANS (Dollars in Thousands)

Arrow sponsors qualified and non-qualified defined benefit pension plans and other postretirement benefit plans for its employees. Arrow maintains a non-contributory pension plan, which covers substantially all employees. Arrow also maintains a supplemental non-qualified unfunded retirement plan to provide eligible employees of Arrow and its subsidiaries with benefits in excess of qualified plan limits imposed by federal tax law.

Arrow has multiple non-pension postretirement benefit plans.  The health care, dental and life insurance plans are contributory, with participants’ contributions adjusted annually.  Arrow’s policy is to fund the cost of postretirement benefits based on the current cost of the underlying policies.  However, the health care plan provision allows for grandfathered participants to receive automatic increases of Company contributions each year based on the increase in inflation, limited to a maximum of 5%.

The following tables provide the components of net periodic benefit costs for the three and nine-month periods ended September 30, 2025 and 2024:
