Liabilities, Interest, Present Value & Bond Valuation(负债、利息、现值与债券估值)


1. Sources of Financing(融资来源)

  • 1.1 Debt Financing – Funds from Creditors(债务融资——来自债权人的资金)

    • Essence / 本质: Borrowed money that must be repaid with interest. (向外部借入资金,将来必须连本带息偿还。)

    • Features / 特点:

      • Legal obligation to pay interest and principal.(利息与本金是法律义务。)
      • Creditors can force bankruptcy if unpaid.(未支付时债权人可以申请破产清算。)
    • Advantages / 优点:

      • Interest is tax-deductible.(利息可税前抵扣。)
      • No ownership dilution.(不会稀释现有股东持股。)
    • Capital structure / 资本结构:

      • Mix of debt and equity affects risk, return, and control. (债务与权益的组合会影响企业风险、收益与控制权。)
  • 1.2 Equity Financing – Funds from Owners(权益融资——来自所有者的资金)

    • Essence / 本质: Owners contribute capital in exchange for ownership (shares). (所有者投入资金换取股权。)

    • Features / 特点:

      • Dividends are not legal obligations.(股利不是法律义务,可选择不发。)
      • Residual claim on assets and profits.(股东对剩余资产和利润拥有索取权。)
    • Flexibility / 灵活性:

      • No fixed repayment schedule; improves solvency but可导致股权被摊薄。
  • 1.3 Risk Comparison: Debt vs Equity(风险比较:债务 vs 权益)

    • Debt is riskier for the company because:

      • Interest is a legal obligation.(利息支付刚性。)
      • Creditors can force bankruptcy.(债权人可通过法律程序强制破产。)
    • Equity is riskier for investors (residual claim) but safer for company solvency. (权益对投资者风险更高,但对企业偿债能力更安全。)


2. Liabilities Overview(负债概念与分类)

  • 2.1 Definition of Liabilities(负债的定义)

    • Definition / 定义: Probable future sacrifices of economic benefits arising from present obligations from past transactions. (由于过去交易形成的现时义务,预计将导致未来经济利益的流出。)
    • Usually paid with assets or services.(通常用现金、其他资产或劳务偿还。)
  • 2.2 Classification: Current vs Noncurrent(分类:流动与非流动负债)

    • Current liabilities(流动负债):

      • Maturity within 1 year or the operating cycle.(一年或营业周期内到期。)
      • Examples: A/P, short-term notes, wages payable, taxes payable, current portion of long-term debt.
    • Noncurrent liabilities(非流动负债):

      • Maturity > 1 year.(一年以上到期。)
      • Examples: long-term notes, bonds payable, long-term leases.
  • 2.3 Measurement at Present Cash Equivalent(按现时现金等价物计量)

    • Current cash equivalent / 当前现金等价价值: Amount a creditor would accept today to cancel the debt. (债权人今天愿意接受以了结债务的金额。)
    • Essentially the present value of future cash outflows
  • 2.4 Common Liability Accounts(常见负债账户)

    • 2.4.1 Accounts Payable / Trade Accounts Payable(应付账款)

      • Formal written obligations, often with an explicit interest rate and maturity date. (书面票据形式的负债,通常注明利率和到期日。)
    • 2.4.4 Deferred / Unearned Revenues(递延/预收收入)

      • Cash received before revenue is earned; obligation to provide goods/services. (先收款后履约,对客户负有提供商品或服务的义务。)

3. Liquidity Measures(短期偿债能力指标)

  • 3.1 Current Ratio(流动比率)

    • Formula / 公式:
    • Interpretation / 含义: Higher ratio → stronger ability to pay short-term obligations. (比率越高,短期偿债能力越强;过高可能说明资产运用效率低。)
  • 3.2 Working Capital(营运资金)

    • Formula / 公式:
    • Interpretation / 含义: Positive working capital indicates a buffer of liquid resources. (为正说明企业有一定安全垫,可支持日常运营。)
  • 3.3 Accounts Payable Turnover Ratio(应付账款周转率)

    • Formula / 公式:

    • Interpretation / 含义:

      • Higher turnover → pay suppliers quickly.(周转率高表示付款速度快。)
      • Can be converted to days payable outstanding:

4. Notes Payable & Interest(应付票据与利息)

  • 4.1 Interest Basics(利息基础)

    • Formula / 公式:
    • Time = 1 for full year; fraction (e.g., (2/12)) for partial year. (一年记为 1,少于一年按月数或天数折成分数。)
  • 4.2 Lender vs Borrower Perspective(债权人与债务人视角)

    • To the lender, interest = interest revenue.(对出借方是利息收入。)
    • To the borrower, interest = interest expense.(对借款方是利息费用。)
  • 4.3 Example: Starbucks Short-Term Note(短期票据示例)

    • Borrow $100,000, 12% annual, 2 months:
  • 4.4 Long-Term Notes at Present Value(长期票据按现值入账)

    • Record note and related asset at PV of future payment using market rate.
    • Example:FV $200,000, market rate 12%, (n=2):
  • 4.5 Effective Interest Method(实际利率法)

    • Each period:
    • For discount notes, carrying amount increases toward face value; for premium notes, it decreases.

5. Contingent Liabilities(或有负债)

  • 5.1 Probability vs Estimability Table(可能性与可计量性矩阵)

    • Probable + Estimable(很可能且可估计) → Record liability and expense.(确认负债与费用。)
    • Probable / Reasonably possible + Not estimable(难以估计金额) → Disclose in notes.(仅在附注披露。)
    • Remote(可能性极低) → No action.(无需确认或披露。)
  • 5.2 Typical Examples(典型例子)

    • Lawsuits, guarantees, environmental obligations, warranties. (诉讼、担保、环境治理义务、产品保修等。)

6. Long-Term Liabilities(长期负债)

    • Obligations with maturity greater than one year / operating cycle. (到期时间超过一年或一个营业周期的债务。)
    • Current portion of long-term debt should be reclassified as current liability. (一年内到期部分需单独列示为流动负债。)
  • 6.2 Collateral & Pledges(抵押与质押)

    • Creditors may require borrowers to pledge assets as security. (债权人常要求以固定资产或其他资产作抵押。)
    • Pledged assets must be disclosed in notes because they reduce flexibility. (被抵押资产通常需在附注中披露,会降低企业财务弹性。)
  • 6.3 Financing Channels: Loans vs Bonds(筹资渠道:贷款 vs 债券)

    • Small long-term needs → bank loans, insurance companies, pension funds.
    • Large long-term needs → issue bonds to many investors.

7. Present Value Concepts(现值概念)

  • 7.1 Time Value of Money(货币时间价值)

    • A dollar today is worth more than a dollar in the future because it can earn interest. (今天的一元因可立即投资生息,价值大于未来的一元。)
  • 7.2 Four Key Variables(四个关键变量)

    • Present value (PV)、Future value (FV)、Interest rate (r)、Number of periods (n)。
    • Knowing any three allows solving for the fourth.(已知任意三者即可求出剩下一项。)
  • 7.3 Tools for PV Calculations(现值计算工具)

    • Present value tables(现值表)
    • Financial calculators(金融计算器)
    • Excel functions (PV, FV, RATE, NPER 等)

8. Present Value of a Single Amount(单笔金额现值)

  • 8.1 Definition & Timeline(定义与时间轴)

    • PV = today’s value of a future single cash flow. (现值是单笔未来现金流折算到今天的价值。)
    • Timeline: future value at time (n) discounted back to time 0.
  • 8.2 Core Formulas(核心公式)

    • Future value:
    • Present value:
  • 8.3 Example: $1,331 in 3 Years at 10%(例子)

    • Using PV table factor 0.7513:

9. Present Value of an Annuity(年金现值)

  • 9.1 Definition of Annuity(年金定义)

    • Series of equal payments at regular intervals (ordinary annuity if at period end). (在固定间隔内支付等额现金流;期末支付为普通年金。)
  • 9.2 PV of Annuity(年金现值公式)

    • Equivalent to discounting each payment and summing:
  • 9.3 Example: $1,000 Each Year for 3 Years at 10%(示例)

    • Table factor:(PVIFA(10%,3) = 2.4869)

10. Accounting Applications of PV – Long-Term Notes(现值在长期票据中的会计应用)

  • 10.1 Initial Recognition at PV(按现值初始确认)

    • Record asset and note payable at PV of future payment using market rate.

    • Example:

      • (FV = 200{,}000)、(r = 12%)、(n = 2):
      • Entry:Dr Delivery trucks 159,440 / Cr Notes payable 159,440。
  • 10.2 Effective Interest Method(实际利率法)

    • Year 1 interest expense:
    • Entry:Dr Interest expense 19,133 / Cr Notes payable 19,133。
    • Year 2 interest expense:
  • 10.3 Final Settlement(到期偿还)

    • When carrying amount reaches face value 200,000:

      • Dr Notes payable 200,000
      • Cr Cash 200,000

11. Future Value Concepts(终值概念)

  • 11.1 FV of Single Amount(单笔金额终值)

    • Formula / 公式:
    • Example:(PV = 1{,}000, r = 10%, n = 3):
  • 11.2 FV of an Annuity(年金终值)

    • Formula / 公式:
    • Example:$1,000 each year, 10%, 3 years:

12. Bond Valuation Basics(债券估值基础)

  • 12.1 Bond Cash Flows(债券现金流)

    • Periodic interest (coupon) = face value × stated rate.
    • Principal (face value) repaid at maturity.
  • 12.2 Pricing by Present Value(用现值定价)

    • Bond price = PV of interest annuity + PV of principal
    • All discounted at market/effective rate (r)。
  • 12.3 Stated vs Effective Interest Rate(票面利率 vs 实际利率)

    • Stated rate → determines cash interest (C = F \times \text{stated rate})。
    • Effective (market) rate → determines economic return & price
  • 12.4 Par, Premium, Discount(平价、溢价、折价)

    • Stated = effective → price = face value (par).
    • Stated > effective → price > face value (premium).
    • Stated < effective → price < face value (discount).

13. Bond Valuation Terminologies(债券估值术语)

  • 13.1 Face Value(面值)

    • Principal repaid at maturity date.(到期偿还的本金金额。)
  • 13.2 Bond Premium(债券溢价)

    • Issue price − face value when price > face. (发行价高于面值的差额。)
  • 13.3 Bond Discount(债券折价)

    • Face value − issue price when price < face. (面值高于发行价的差额。)
  • 13.4 Amortized Cost / Book Value(摊余成本 / 账面价值)

    • Carrying amount = PV of remaining cash flows discounted at original effective rate.
    • Changes each period via effective interest method;趋近于面值。
  • 13.5 Fair Value vs Carrying Amount(公允价值 vs 账面金额)

    • Fair value uses current market rate at day t.
    • Carrying amount uses original effective rate at purchase date.

14. Discount Bond Example – Debt Instrument(折价债券示例:债务工具)

  • 14.1 Initial Purchase at Discount(初始折价购买)

    • Term 5 years; face value 1,000。
    • Price computed as: where coupon (59 = 1{,}250 \times 4.7%)。
  • 14.2 Carrying Amount After 1 Year(一年后的账面价值)

    • Remaining 4 coupons + principal discounted at 10%:
    • Carrying amount > purchase price because effective rate > stated rate. (因实际利率高于票面利率,账面价值随着折价摊销逐年上升。)
  • 14.3 Key Insights(关键理解)

    • Discount represents extra yield beyond coupon interest. (折价提供了超出票息的额外收益。)
    • Over time, carrying amount accretes upward to face value $1,250 at maturity. (随时间推移,账面价值逐渐接近并最终等于面值 1,250。)
