Understanding our Pension Benefits Table The WestRock Pension Plan (now frozen) provides an unreduced benefit payable at age 65 (or 62, if the employee has 20 years of service). The retirement benefit payable is equal to 1.6% of final average earnings (or pay) times years of benefit service (up to a maximum of 40 years), minus an employee’s primary social security benefit multiplied by 1.25% times years of benefit service (up to a maximum of 40 years of service). The formula is illustrated below: [1.6% x Years of Benefit x Final Average Pay] Service (up to 40) Less [1.25% x Years of Benefit x Primary Social Security Benefit] Service (up to 40) The Retirement Restoration Plan mirrors benefits provided under the WestRock Pension Plan following the same formula but recognizing compensation in excess of Code limits.

The underlying plan, the WestRock Pension Plan, to which our Retirement Restoration Plan relates, was frozen on December 31, 2015. Accordingly, the values above represent a historic liability accrued under the WestRock Pension Plan with respect to service performed for WestRock, not Ingevity.
