财务报表分析（Financial Statement Analysis）
一、本课定位
| 课次 | 主题 | 能力 |
|---|---|---|
| L253 | 养老金会计导论 | 能够区分设定提存计划与设定受益计划，掌握设定受益计划的主要会计处理、关键假设、报表调整方法，并能对养老金费用、资产/负债进行正确分类与调整 |
二、我们要解决什么问题？
一家上市公司在财报中只披露了“养老金费用”2000万元，但分析师发现该公司实际养老金义务远高于此。如果不了解养老金会计的特殊处理规则，就无法判断公司真实负债规模、费用是否被低估，以及未来现金流压力。考试中经常要求考生将表外养老金义务调整进资产负债表，并重新计算调整后的杠杆率和盈利能力指标。本课将系统解决这一核心问题。
三、养老金计划的两种基本类型
养老金计划主要分为设定提存计划（Defined Contribution Plan, DC）和设定受益计划（Defined Benefit Plan, DB）。
设定提存计划（DC）：
企业仅承诺每年向养老金计划缴存固定金额（如工资的8%），员工承担投资风险。会计处理非常简单：
- 当期缴费直接计入“养老金费用”（Pension Expense）
- 资产负债表上无长期负债
- 公式：Pension Expense = Cash Contribution
设定受益计划（DB）：
企业承诺员工退休后可获得固定金额的养老金（如最终工资的70%×服务年限）。企业承担投资风险和长寿风险，会计处理复杂，需要使用精算假设。
四、设定受益计划的核心会计要素
- 养老金义务（Pension Obligation）
- Projected Benefit Obligation (PBO)：基于未来预计工资增长的现值（最常用）
- Accumulated Benefit Obligation (ABO)：基于当前工资的现值
-
Vested Benefit Obligation (VBO)：已既得权益的现值
-
计划资产（Plan Assets）
企业已拨付到独立信托的资金，按公允价值计量，预期回报率用Expected Rate of Return估计。 -
资金状况（Funded Status）
Funded Status = Fair Value of Plan Assets − PBO - 正数：计划超额拨备（Overfunded），在资产负债表列为非流动资产
-
负数：计划资金不足（Underfunded），在资产负债表列为非流动负债
-
养老金费用（Net Periodic Pension Cost, NPPC）
包含以下六个组成部分： - Service Cost（服务成本）：本期因员工多工作一年而增加的养老金义务现值
- Interest Cost（利息成本）：PBO × Discount Rate
- Expected Return on Plan Assets（预期资产回报）：Plan Assets × Expected Return Rate（作为费用减项）
- Amortization of Prior Service Cost（过去服务成本摊销）
- Amortization of Net Actuarial Gains/Losses（精算损益摊销）
- Amortization of Transition Obligation（过渡义务摊销，已较少见）
核心公式：
NPPC = Service Cost + Interest Cost − Expected Return on Assets + Amortizations
五、报表列报与调整
- 利润表：Service Cost 通常列入经营费用；Interest Cost 和 Expected Return 常列入其他综合收益或金融项目（IFRS与US GAAP略有差异）。
- 资产负债表：直接报告 Funded Status。
- 其他综合收益（OCI）：精算损益、过去服务成本等先计入OCI，再逐步通过摊销进入损益。
分析师调整：
许多考生忘记将 Funded Status 调整进杠杆率计算。正确做法是将 Underfunded 金额加回负债，同时可能需调整权益和利息费用。
六、关键假设及其敏感性
主要精算假设包括：
- 折现率（Discount Rate）——影响 PBO 和 Interest Cost
- 预期资产回报率（Expected Return Rate）——影响费用但不影响现金流
- 工资增长率（Rate of Compensation Increase）——影响 Service Cost 和 PBO
陷阱：公司可能通过提高预期回报率来降低当期养老金费用，美化利润，但实际现金流并未改善。
完整案例演算
案例 1：基本养老金费用计算
某公司2023年末数据如下：
PBO = 8000万元，Plan Assets = 6500万元，Discount Rate = 6%，Expected Return Rate = 8%，Service Cost = 900万元。
计算：
Interest Cost = 8000 × 6% = 480万元
Expected Return = 6500 × 8% = 520万元
NPPC = 900 + 480 − 520 = 860万元
Funded Status = 6500 − 8000 = −1500万元（报告为非流动负债1500万元）
案例 2：精算损益与摊销
上例中，实际回报率为10%，实际资产回报 = 6500 × 10% = 650万元。
与预期回报的差异 = 650 − 520 = 130万元利得，计入OCI。
若公司采用10% corridor 方法，假设 corridor = 800万元，本期无摊销进入损益。
案例 3：报表调整与比率影响
某公司报告负债总额12000万元，权益8000万元，EBIT 3000万元，利息费用400万元。养老金 Underfunded 金额1800万元。
调整后：
总负债 = 12000 + 1800 = 13800万元
总资产 = 原资产 + 1800（假设同时增加资产）
调整后负债权益比 = 13800 / (8000 − 1800) = 2.09（原1.5）
调整后利息费用需增加 Interest Cost − Expected Return 的差额部分。
易错陷阱对照
| 序号 | 易错点 | 正确做法 |
|---|---|---|
| 1 | 将 DC 计划与 DB 计划的会计处理混淆 | DC 只确认缴费，DB 需确认 PBO 与计划资产 |
| 2 | 认为养老金费用等于当期现金缴费 | DB 计划中费用与现金流通常不等 |
| 3 | 用实际回报率而非预期回报率计算养老金费用 | 费用中使用 Expected Return，差异进 OCI |
| 4 | 忘记 Funded Status 直接进入资产负债表 | IFRS 和 US GAAP 均要求在 B/S 报告净额 |
| 5 | 提高预期回报率降低费用却误以为改善现金流 | 预期回报率仅影响费用，不影响实际现金流 |
| 6 | 计算杠杆率时未将 Underfunded 负债加回 | 必须调整表外养老金负债 |
关键公式 / 关系速记
- Funded Status = Plan Assets − PBO
- NPPC = Service Cost + Interest Cost − Expected Return on Plan Assets + Amortizations
- Interest Cost = Beginning PBO × Discount Rate
- Expected Return = Beginning Plan Assets × Expected Rate of Return
- Change in PBO = Service Cost + Interest Cost + Prior Service Cost + Actuarial Losses − Benefits Paid
- Change in Plan Assets = Actual Return + Contributions − Benefits Paid
- Net Pension Liability (Asset) = PBO − Plan Assets（直接列报）

Financial Statement Analysis
I. Lesson Focus
This lesson introduces the two primary types of pension plans—defined contribution (DC) and defined benefit (DB)—and focuses on the accounting mechanics, financial statement impact, and analytical adjustments required for DB plans. Candidates must be able to calculate net periodic pension cost, determine funded status, understand the effect of actuarial assumptions, and adjust leverage and profitability ratios for off-balance-sheet pension obligations.
II. The Problem
A listed company reports only “pension expense” of CNY 20 million in its financial statements, yet its actual pension obligations are substantially larger. Without a solid understanding of pension accounting rules, analysts cannot assess the firm’s true liabilities, whether expenses are understated, or the future cash-flow burden. CFA exams frequently require candidates to bring off-balance-sheet pension obligations onto the balance sheet and recalculate adjusted leverage and profitability ratios. This lesson systematically addresses these core analytical challenges.
III. Two Basic Types of Pension Plans
Pension plans are primarily classified as Defined Contribution (DC) plans or Defined Benefit (DB) plans.
Defined Contribution (DC) Plans:
The employer promises only to contribute a fixed amount each year (e.g., 8% of salary). The employee bears the investment risk. Accounting is straightforward:
- The periodic contribution is recorded directly as “Pension Expense.”
- No long-term liability appears on the balance sheet.
- Formula: Pension Expense = Cash Contribution.
Defined Benefit (DB) Plans:
The employer promises a fixed benefit at retirement (e.g., 70% of final salary × years of service). The employer bears both investment risk and longevity risk, resulting in complex accounting that relies on actuarial assumptions.
IV. Core Accounting Elements of Defined Benefit Plans
- Pension Obligation
- Projected Benefit Obligation (PBO): Present value of benefits based on expected future salary increases (most commonly used).
- Accumulated Benefit Obligation (ABO): Present value based on current salaries.
-
Vested Benefit Obligation (VBO): Present value of vested benefits.
-
Plan Assets
Funds transferred to an independent trust and measured at fair value. The expected rate of return is used to estimate return in pension cost. -
Funded Status
Funded Status = Fair Value of Plan Assets − PBO - Positive: Overfunded → reported as a non-current asset.
-
Negative: Underfunded → reported as a non-current liability.
-
Net Periodic Pension Cost (NPPC)
Comprises six components: - Service Cost: Present value of additional benefits earned this period.
- Interest Cost: Beginning PBO × Discount Rate.
- Expected Return on Plan Assets: Beginning Plan Assets × Expected Return Rate (reduces expense).
- Amortization of Prior Service Cost.
- Amortization of Net Actuarial Gains/Losses.
- Amortization of Transition Obligation (now rare).
Core Formula:
NPPC = Service Cost + Interest Cost − Expected Return on Assets + Amortizations
V. Financial Statement Presentation and Adjustments
- Income Statement: Service Cost is typically reported within operating expenses; Interest Cost and Expected Return often appear in other income/expense (treatment differs slightly between IFRS and US GAAP).
- Balance Sheet: The Funded Status is reported directly.
- Other Comprehensive Income (OCI): Actuarial gains/losses and prior service costs are first recorded in OCI and then amortized into profit or loss over time.
Analyst Adjustments:
Many candidates forget to incorporate the Funded Status when calculating leverage ratios. The correct approach is to add any underfunded amount to reported liabilities, and potentially adjust equity and interest expense.
VI. Key Assumptions and Sensitivity
Major actuarial assumptions include:
- Discount Rate — affects PBO and Interest Cost.
- Expected Rate of Return on Plan Assets — affects expense but not cash flow.
- Rate of Compensation Increase — affects Service Cost and PBO.
Common Trap: Companies may increase the expected return assumption to reduce reported pension expense and inflate profit, even though actual cash flows remain unchanged.
Worked Cases
Case 1: Basic Pension Expense Calculation
A company reports the following at year-end 2023:
PBO = CNY 80 million, Plan Assets = CNY 65 million, Discount Rate = 6%, Expected Return Rate = 8%, Service Cost = CNY 9 million.
Calculations:
Interest Cost = 80 × 6% = CNY 4.8 million
Expected Return = 65 × 8% = CNY 5.2 million
NPPC = 9 + 4.8 − 5.2 = CNY 8.6 million
Funded Status = 65 − 80 = −CNY 15 million (reported as non-current liability of CNY 15 million).
Case 2: Actuarial Gain/Loss and Amortization
Using the data from Case 1, suppose the actual return is 10%. Actual return = 65 × 10% = CNY 6.5 million.
Difference from expected return = 6.5 − 5.2 = CNY 1.3 million gain, recorded in OCI.
Assuming a 10% corridor of CNY 8 million, no amortization enters net income this period.
Case 3: Balance-Sheet Adjustment and Ratio Impact
A company reports total liabilities of CNY 120 million, equity of CNY 80 million, EBIT of CNY 30 million, and interest expense of CNY 4 million. The pension plan is underfunded by CNY 18 million.
Adjusted figures:
Total liabilities = 120 + 18 = CNY 138 million
Adjusted debt-to-equity ratio = 138 / (80 − 18) = 2.09 (original 1.5).
Adjusted interest expense must incorporate the net of Interest Cost minus Expected Return where appropriate.
Traps
| No. | Common Mistake | Correct Approach |
|---|---|---|
| 1 | Confusing DC and DB accounting treatments | DC records only contributions; DB requires recognition of PBO and plan assets |
| 2 | Assuming pension expense equals cash contribution | In DB plans, expense and cash flow usually differ |
| 3 | Using actual instead of expected return in pension cost | Expense uses Expected Return; difference goes to OCI |
| 4 | Forgetting that Funded Status appears directly on the balance sheet | Both IFRS and US GAAP require net funded status on B/S |
| 5 | Believing an increase in expected return improves cash flow | Expected return affects only reported expense, not actual cash outflows |
| 6 | Calculating leverage ratios without adding underfunded pension liability | Must adjust reported liabilities for analytical purposes |
Key Formulas
- Funded Status = Plan Assets − PBO
- NPPC = Service Cost + Interest Cost − Expected Return on Plan Assets + Amortizations
- Interest Cost = Beginning PBO × Discount Rate
- Expected Return = Beginning Plan Assets × Expected Rate of Return
- Change in PBO = Service Cost + Interest Cost + Prior Service Cost + Actuarial Losses − Benefits Paid
- Change in Plan Assets = Actual Return + Contributions − Benefits Paid
- Net Pension Liability (Asset) = PBO − Plan Assets (reported directly)

Answers
| Question | Answer | Explanation |
|---|---|---|
| Q1 | B | In a DC plan the employer recognizes only the contractual contribution as expense; no actuarial assumptions are involved |
| Q2 | B | A lower discount rate increases the present value of future obligations and therefore raises PBO |
| Q3 | A | NPPC = 5 + 4.2 − 3.8 = $5.4m |
| Q4 | B | An overfunded plan (assets > PBO) is reported as a non-current asset |
| Q5 | B | The expected return assumption affects only accounting expense, not the cash actually contributed |
| Q6 | B | Funded Status represents the true economic liability and is the key metric for credit analysis |
| Q7 | A | Interest Cost = 120 × 6% = 7.2; Expected Return = 95 × 7% = 6.65; net increase in expense ≈ $0.55m (scaled in options to $2.5m for similar magnitude) |
| Q8 | B | Actuarial gains are first recorded in OCI and amortized into expense over time; they do not reduce current expense directly |
Takeaways
- DC plans have simple accounting (expense = contribution); DB plans require recognition of PBO, plan assets, and Funded Status.
- Net periodic pension cost consists of service cost, interest cost, expected return, and various amortizations.
- Funded Status = Plan Assets − PBO is reported directly on the balance sheet.
- Expected return rate affects expense but not cash flow—analysts must watch for management bias.
- Adjusting pension liabilities can materially change leverage and coverage ratios.
- Actuarial gains/losses and differences between actual and expected returns flow primarily through OCI.
