FAR Pension Accounting: Net Periodic Cost and OCI Explained

By CPA Sprint · Updated February 2026

Pension accounting on FAR tests your ability to identify the five components of net periodic pension cost, determine what flows through the income statement versus other comprehensive income, and calculate the funded status reported on the balance sheet. This is one of the most calculation-heavy topics in Area II, and it rewards candidates who have a systematic approach.

Key Points

  • Net periodic pension cost has five components; only service cost is classified as an operating expense under ASC 715
  • Prior service cost and net actuarial gains/losses bypass the income statement and go to OCI
  • The projected benefit obligation (PBO) is the present value of all benefits earned, reflecting expected future salary increases
  • Funded status (PBO minus fair value of plan assets) is reported on the balance sheet as a net asset or net liability
  • The corridor approach (10% of the greater of PBO or plan assets) governs amortization of accumulated gains and losses
  • Expected return on plan assets reduces pension expense; actual return determines the gain/loss that goes to OCI

What are the components of net periodic pension cost?

ASC 715 defines five components that make up the net periodic pension cost (commonly called "pension expense") reported each period. Understanding each component and where it is reported is the foundation of every pension question on FAR.

ComponentDescriptionIncome Statement or OCI?Operating or Non-Operating?
Service costPresent value of benefits earned by employees during the current periodIncome statementOperating expense
Interest costInterest on the PBO at the discount rate (beginning PBO x discount rate)Income statementNon-operating (below the line)
Expected return on plan assetsExpected earnings on plan assets; reduces pension expense (shown as a negative)Income statementNon-operating (below the line)
Amortization of prior service costAmortization of the cost of retroactive benefits granted by plan amendmentsIncome statementNon-operating (below the line)
Amortization of net gain or lossAmortization of accumulated actuarial gains/losses that exceed the corridorIncome statementNon-operating (below the line)

The formula is:

Net periodic pension cost = Service cost + Interest cost - Expected return on plan assets + Amortization of prior service cost + Amortization of net loss (or - Amortization of net gain)

What is the projected benefit obligation (PBO)?

The PBO represents the total pension obligation as of the measurement date. It is calculated as the present value of all benefits employees have earned, using assumptions about future salary levels. This distinguishes it from the accumulated benefit obligation (ABO), which uses current salary levels.

The PBO rolls forward each period using this formula:

  1. Beginning PBO
  2. + Service cost (benefits earned during the period)
  3. + Interest cost (beginning PBO x discount rate)
  4. + Prior service cost (retroactive benefits from plan amendments during the period)
  5. +/- Actuarial losses/gains (changes in assumptions or experience different from expected)
  6. - Benefits paid (payments made to retirees)
  7. = Ending PBO

Worked example

A company has the following pension data for the year:

ItemAmount
Beginning PBO$1,000,000
Discount rate6%
Service cost$80,000
Benefits paid$55,000
Actuarial loss (change in assumptions)$25,000

Ending PBO calculation:

  1. Beginning PBO: $1,000,000
  2. Add service cost: + $80,000
  3. Add interest cost ($1,000,000 x 6%): + $60,000
  4. Add actuarial loss: + $25,000
  5. Subtract benefits paid: - $55,000
  6. Ending PBO: $1,110,000

What goes to OCI vs the income statement?

This is the single most-tested distinction in pension accounting on FAR. Two categories of items bypass the income statement entirely when they arise and go directly to other comprehensive income (OCI):

ItemWhen It ArisesInitial RecognitionSubsequent Treatment
Net actuarial gains and lossesDifferences between expected and actual plan experience; changes in actuarial assumptions (discount rate, mortality, turnover)OCI (bypasses income statement)Amortized into net periodic pension cost using the corridor approach
Prior service costPlan amendments that grant retroactive benefits to employeesOCI (bypasses income statement)Amortized into net periodic pension cost over the average remaining service period of affected employees

These items accumulate in accumulated other comprehensive income (AOCI) on the balance sheet until they are amortized into pension expense.

Items that go directly to the income statement each period (as components of net periodic pension cost):

  • Service cost
  • Interest cost
  • Expected return on plan assets
  • Amortization of prior service cost (from AOCI)
  • Amortization of net gain or loss (from AOCI)

How do plan assets work?

Plan assets are the investments held in the pension trust to fund future benefit payments. The plan asset balance rolls forward similarly to the PBO:

  1. Beginning fair value of plan assets
  2. + Actual return on plan assets (investment gains, interest, dividends)
  3. + Employer contributions
  4. - Benefits paid (payments to retirees)
  5. = Ending fair value of plan assets

Expected vs actual return

This distinction is critical and generates a significant share of exam questions.

  • Expected return on plan assets is used in the net periodic pension cost calculation. It equals the beginning fair value of plan assets multiplied by the expected long-term rate of return.
  • Actual return on plan assets is what the investments actually earned.
  • The difference (actual return minus expected return) is an actuarial gain or loss that goes to OCI.
ScenarioActual ReturnExpected ReturnDifferenceEffect on OCI
Assets outperform expectations$90,000$70,000+$20,000Gain to OCI (credit)
Assets underperform expectations$50,000$70,000-$20,000Loss to OCI (debit)
Assets match expectations$70,000$70,000$0No OCI entry

Funded status

The balance sheet reports the funded status of the pension plan:

Funded status = Fair value of plan assets - PBO

  • If plan assets exceed the PBO: report a net pension asset (noncurrent asset)
  • If the PBO exceeds plan assets: report a net pension liability (noncurrent liability)

This is the only pension amount reported on the balance sheet. The funded status is not the same as net periodic pension cost.

What is the corridor approach?

The corridor approach governs when accumulated net actuarial gains and losses in AOCI must be amortized into pension expense. It is designed to prevent small fluctuations from affecting reported earnings.

  1. Calculate the corridor: 10% of the greater of the beginning PBO or the beginning market-related value of plan assets
  2. Compare the corridor to the beginning balance of accumulated net gain or loss in AOCI
  3. If the accumulated balance exceeds the corridor, amortize the excess over the average remaining service period of active employees
  4. If the accumulated balance is within the corridor, no amortization is required

Worked example

ItemAmount
Beginning PBO$2,000,000
Beginning fair value of plan assets$1,800,000
Accumulated net loss in AOCI$250,000
Average remaining service period10 years
  1. Corridor = 10% x greater of ($2,000,000, $1,800,000) = 10% x $2,000,000 = $200,000
  2. Accumulated net loss ($250,000) exceeds corridor ($200,000) by $50,000
  3. Amortization = $50,000 / 10 years = $5,000 added to net periodic pension cost

What are the most common pension exam traps?

TrapWhat Candidates Do WrongCorrect Approach
Confusing service cost with total pension expenseReport only service cost as pension expenseService cost is one of five components; calculate all five
Using actual return instead of expected return in expensePlug the actual return into the net periodic pension cost formulaUse expected return in the expense calculation; the difference goes to OCI
Forgetting to amortize prior service costOmit the amortization component from the expense calculationCheck whether there is a prior service cost balance in AOCI and amortize if present
Wrong corridor calculation baseUse the smaller of PBO or plan assetsThe corridor is 10% of the greater of beginning PBO or beginning plan assets
Reporting pension expense on the balance sheetRecord the computed expense as the balance sheet liabilityThe balance sheet reports funded status (plan assets minus PBO), not expense
Misclassifying components as operatingReport interest cost or expected return as operating itemsOnly service cost is operating; all other components are non-operating

How should you approach pension questions on FAR?

Use this sequence for any pension question on exam day:

  1. Identify what the question is asking. Is it asking for net periodic pension cost, a single component, the funded status, the OCI impact, or the journal entry? Read the requirement before doing any math.
  2. List the five components. Write them down: S-I-E-A-A (Service cost, Interest cost, Expected return, Amortization of prior service cost, Amortization of net gain/loss). Check off which ones the question provides data for.
  3. Calculate interest cost. Beginning PBO x discount rate. Verify you are using beginning-of-year PBO, not ending.
  4. Calculate expected return. Beginning fair value of plan assets x expected rate of return. Do not use actual return here.
  5. Check for corridor amortization. If the question provides an accumulated gain/loss balance in AOCI, calculate the corridor (10% of the greater of beginning PBO or beginning plan assets) and determine whether amortization is required.
  6. Assemble the answer. Add the components together (remembering that expected return is subtracted). If the question asks about OCI, report the items that bypass the income statement: the new actuarial gain/loss and the new prior service cost.
  7. Verify the funded status if asked. Ending plan assets minus ending PBO. This is separate from the expense calculation.

How does this connect to the FAR blueprint?

Pension accounting falls within Area II: Select Balance Sheet Accounts, which represents 30-40% of the FAR exam per the AICPA Uniform CPA Examination Blueprints effective January 1, 2026. The specific skill tested is the ability to calculate net periodic pension cost, determine funded status, and classify items between the income statement and OCI under ASC 715.

For additional FAR technical topics, see our guides on bonds and the effective interest method and practice question strategy for FAR. For a complete study approach, see how to pass the FAR CPA exam.

The authoritative guidance for pension accounting is ASC 715, Compensation — Retirement Benefits, as amended by ASU 2017-07. The exam scope is defined by the AICPA Uniform CPA Examination Blueprints, effective January 1, 2026.

Frequently Asked Questions

How many pension questions are on the FAR exam?

The AICPA does not publish exact question counts by topic. Pension accounting falls within Area II: Select Balance Sheet Accounts (30-40% of the exam). Based on the blueprint weighting, candidates can expect 2-5 MCQs and potentially one TBS that involves pension calculations or classification. The topic is tested frequently enough that skipping it is not a viable strategy.

What is the projected benefit obligation (PBO)?

The PBO is the present value of all pension benefits earned by employees to date, measured using assumptions about future salary increases. It represents the employer's total obligation under the plan. The PBO increases with service cost, interest cost, plan amendments, and actuarial losses, and decreases with benefits paid to retirees and actuarial gains.

What pension components go to OCI instead of the income statement?

Two types of items bypass the income statement and go directly to other comprehensive income: (1) net actuarial gains and losses arising from changes in assumptions or differences between expected and actual experience, and (2) prior service cost from plan amendments. These items accumulate in accumulated other comprehensive income (AOCI) and are amortized into net periodic pension cost over time.

Do I need to memorize the corridor approach for FAR?

Yes. The corridor approach determines whether accumulated net gains or losses in AOCI must be amortized into pension expense. The corridor equals 10% of the greater of the PBO or the market-related value of plan assets at the beginning of the year. Only the excess above the corridor is amortized, divided by the average remaining service period of active employees.

Are pensions tested in MCQs or TBS on FAR?

Both. MCQs typically test component identification (which items are included in net periodic pension cost, what goes to OCI) and simple calculations. TBS may require computing the full net periodic pension cost, determining the funded status, or preparing journal entries. TBS questions often provide a data table and ask you to complete a schedule.
