Types of Plans（GAAP）
Defined Contribution Plan（401-K）specifies the periodic amount of contributions to the plan.
Defined Benefit Plan defines the benefits to be paid to employees at retirement.Contributions are computed using actuarial assumptions of future benefit payments.
Definitions of Pension Plans
Accumulated Benefit Obligation（ABO）-The actuarial present value of benefits attributed by a formula based on CURRENT and past compensation level
Projected Benefit Obligation（PBO）–The actuarial present value of all benefits attributed by a formula based on FUTURE compensation level.
Plan assets are assets set aside to provide for pension benefits.Plan assets should be reported at fair value.
Service cost is the present value of all pension benefits earned by company employees in the current year.
Interest cost is the growth in PBO for the period due to the passage of time.
Prior service cost increases the PBO in the period of the plan initiation or amendment and should be amortized to pension expense over the future service periods of the affected employees.
Actuarial Gains and Losses are adjustments to the PBO that arise when the actuary changes one or more of the assumptions used to calculated the PBO.
Benefit payments are paid to pension plan participants after retirement. It reduces the PBO and Plan assets at the same time.
Actual return on plan assets can be calculated based on the fair value of plan assets at the beginning and ending of the period.
