 The Cash Balance Formula is a percentage of pay credited to a hypothetical account, which grows with interest. At retirement, the Cash Balance Account is converted to a monthly pension benefit (further information is included in the Cash Balance Formulas section below). The final benefit from this plan is the sum of the two formulas: the Heritage Formula benefit plus the Cash Balance Formula benefit.

Mr. Crews and Dr. Fleming have pension benefits under a Cash Balance Formula in the Pension Plan and Retirement Plan B, respectively.

Ms. Roeder has pension benefits under two subplans of the Pension Plan due to her transfer between business units. She receives a benefit under the Heritage Formula and a Cash Balance Formula in the Northrop Grumman Electronic Systems Pension Plan, a subplan of the Pension Plan (ES Subplan) based on her employment in this subplan. She also receives a benefit under the Northrop Grumman Retirement Value Plan (RVP Subplan) Cash Balance Formula.
