(3) Amounts are calculated using the following assumptions:

• the NEO retires on the earliest date he/she could receive an unreduced benefit under each plan;

• the form of payment is a single life annuity; and

• the discount rate is 5.72% for the Pension Plan, 5.75% for Retirement Plan B and 5.73% for all other plans. The mortality table is the Pri-2012 White Collar mortality table projected generationally with an adjusted version of Scale MP-2021 for all plans.

#### Pension Plans and Descriptions
Most of the pension plans were closed to new hires in 2008. Prior to that time, the Company consolidated the pension plan provisions from diverse Heritage Formulas to a Cash Balance Formula. Over time, the Company also transitioned officers, including NEOs, from supplemental executive retirement plans to a deferred compensation plan, called the Officers Retirement Account Contribution Plan (ORAC). In addition, all final average pay formulas were frozen as of December 31, 2014.

The pension plans in which NEOs participate are listed below.

• ERISA 2 is the ERISA Supplemental Program 2. This plan makes participants whole for benefits they lose under the Pension Plan due to certain Internal Revenue Code limits.

• Litton Restoration Plan is the Litton Industries, Inc. Restoration Plan 2. This plan makes participants whole for benefits they lose under the Retirement Plan B due to certain Internal Revenue Code limits.

• OSERP II is the Officers Supplemental Executive Retirement Program II. This plan provides a pension benefit for certain Company officers.

• Pension Plan is the Northrop Grumman Pension Plan. This is a tax qualified pension plan covering a broad base of Company employees.

• Retirement Plan B is the Northrop Grumman Retirement Plan “B”. This is a tax qualified pension plan covering a broad base of Company employees.
