Long-Lived Assets: Depreciation, Disposal & Intangibles(长期资产:折旧、处置与无形资产)


1. Overview of Long-Lived Assets(长期资产总览)

1.1 Definition & Role(定义与作用)

  • Long-lived assets: used in operations, not held for resale, provide benefits over multiple periods.(长期资产:用于经营、非为转售,在多个会计期间提供经济利益。)
  • Main categories: tangible assets (PPE), intangible assets, natural resources.(主要类别:有形资产、无形资产、自然资源。)

1.2 Classification Framework(分类框架)

  • Tangible long-lived assets: land, building, machinery, equipment.(有形长期资产:土地、建筑、机器、设备等。)
  • Intangible assets: patents, copyrights, trademarks, goodwill, licenses, software.(无形资产:专利、版权、商标、商誉、牌照、软件等。)
  • Natural resources: oil, minerals, timber.(自然资源:石油、矿藏、林木等。)
  • Non–long-lived assets: cash, accounts receivable, inventory, marketable securities.(非长期资产:现金、应收账款、存货、可出售金融资产等。)

1.3 Cost Principle & Capitalization(成本原则与资本化)

  • Capitalize all costs necessary to acquire asset and make it ready for use.(资本化取得并使资产达到可使用状态的一切必要支出。)
  • Expense vs capitalize: immediate benefit → expense; multi-period benefit → asset.(当期受益→费用,多期受益→资产。)
  • Subsequent expenditures: capitalize only if they increase capacity, efficiency, or useful life.(后续支出只有在提高产能、效率或延长寿命时才资本化。)

2. Property, Plant & Equipment: Acquisition & Costs(固定资产取得与成本构成)

2.1 Typical Cost Components(成本构成要素)

  • Purchase price minus discounts.(购买价减折扣。)
  • Taxes, transportation, installation, testing.(相关税费、运输费、安装费、试运行费用。)
  • Site preparation, legal fees, architectural fees for buildings.(场地平整、法律费用、建筑设计费等。)

2.2 Specific Assets(具体资产处理)

  • Land(土地): purchase price, closing costs, legal fees, commissions, demolition cost net of salvage.(地价、交割费用、律师费、中介费、旧建筑拆除成本减残值等。)
  • Land improvements(土地改良): parking lots, fences, lighting – depreciable.(停车场、围栏、照明等——需要折旧。)
  • Buildings(建筑物): purchase price or construction cost plus necessary related costs.(购建成本及相关必要支出。)
  • Equipment(设备): invoice price, freight, insurance during transit, installation.(发票价、运费、运输途中的保险、安装调试费等。)

2.3 Self-Constructed Assets(自建资产)

  • Include direct materials, labor, and a portion of overhead.(包括直接材料、直接人工及一定比例的制造费用。)
  • Interest capitalization during construction period.(在建期间符合条件的利息予以资本化。)

3. Depreciation Basics(折旧基础)

3.1 Key Concepts(关键概念)

  • Cost(成本): total amount capitalized.(资本化的总金额。)
  • Residual (salvage) value(残值): expected disposal value at end of useful life.(使用结束时预计回收金额。)
  • Useful life(使用年限): time or usage over which asset generates benefits.(资产提供经济利益的时间或使用量。)

3.2 Straight-Line Method(直线折旧法)

  • Formula: Depreciation expense = (Cost − Residual value) ÷ Useful life.(公式:折旧费用 =(成本 − 残值)÷ 使用年限。)
  • Same expense each year; book value declines evenly.(每年折旧额相同,账面价值线性下降。)
  • Appropriate when benefits are consumed evenly.(适用于经济利益均匀消耗的资产。)

3.3 Units-of-Production Method(产量折旧法)

  • Depreciation per unit = (Cost − Residual value) ÷ Total estimated units.(单位折旧额 =(成本 − 残值)÷ 预计总产量。)
  • Period depreciation = Depreciation per unit × Units produced in period.(当期折旧 = 单位折旧额 × 当期产量。)
  • Matches expense with usage/production pattern.(使费用与使用程度/产量匹配。)

3.4 Accelerated Methods(加速折旧法)

  • Double-declining balance (DDB): higher expense early, lower later.(双倍余额递减法:前期折旧多,后期折旧少。)
  • Focus on applying a constant rate to beginning-of-year book value.(按期初账面价值乘以固定折旧率计算。)
  • Better reflects assets that lose value more rapidly in early years.(更适用于早期贬值较快的资产。)

4. Special Depreciation Issues(折旧特殊问题)

4.1 Partial-Year Depreciation(不满一年的折旧)

  • Prorate annual depreciation based on months in use.(按资产投入使用的月份比例分摊年折旧额。) -Textbook often assumes half-year or monthly basis.(教材常用半年法或按月计提。)

4.2 Changes in Estimates(估计变更)

  • Changes in useful life or residual value treated prospectively.(使用年限或残值估计变更采用未来适用法。)
  • New annual depreciation = (Book value − New residual) ÷ Remaining life.(新折旧额 =(当前账面价值 − 新残值)÷ 剩余年限。)

4.3 Depreciation vs Asset Replacement(折旧与资产更新)

  • Depreciation is allocation, not valuation.(折旧是成本分配,而非市价评估。)
  • Large repairs/renewals may be capitalized; routine maintenance is expensed.(大型修理/更新可资本化,日常维护费用化。)

5. Disposal of PPE(固定资产处置)

5.1 General Procedure(通用步骤)

  • Step 1: Update depreciation to disposal date.(步骤1:将折旧更新至处置日。)
  • Step 2: Remove asset cost and accumulated depreciation.(步骤2:结转资产成本和累计折旧。)
  • Step 3: Record proceeds (cash or other consideration).(步骤3:记录处置所得现金或其他对价。)
  • Step 4: Recognize gain or loss = Proceeds − Book value.(步骤4:确认处置收益/损失 = 对价 − 账面价值。)

5.2 Sale at Gain / Loss / No Gain-Loss(出售时的三种结果)

  • Proceeds > Book value → Gain on disposal.(对价 > 账面价值 → 处置收益。)
  • Proceeds < Book value → Loss on disposal.(对价 < 账面价值 → 处置损失。)
  • Proceeds = Book value → No gain or loss.(对价 = 账面价值 → 无收益或损失。)

5.3 Retirement / Scrapping(报废与注销)

  • No proceeds; remove asset and accumulated depreciation.(无对价,仅结转资产及累计折旧。)
  • Entire remaining book value recorded as loss.(剩余账面价值全部计入损失。)

5.4 Nonmonetary Exchanges & Partial Disposal(非货币性交换与部分处置)

  • Exchange of assets may trigger gain/loss based on fair value.(资产交换时以公允价值计量并确认收益/损失。)
  • Partial disposal when part of a larger asset is replaced.(大型资产替换部分构成部分处置。)
  • Must estimate and remove cost and accumulated depreciation for the disposed portion.(需估计被替换部分的成本和累计折旧并结转。)

6. Disposal Journal Entries & Statement Effects(处置分录与报表影响)

6.1 Journal Entry Structure(分录结构)

  • Debit: Cash (if any), Accumulated Depreciation.(借:现金(如有)、累计折旧。)
  • Credit: Asset account.(贷:相关资产科目。)
  • Plug figure: Gain (credit) or Loss (debit).(差额计入处置收益(贷)或处置损失(借)。)

6.2 Impact on Financial Statements(对三大报表的影响)

  • Income statement: gain increases net income, loss decreases.(利润表:处置收益提高净利润,损失降低净利润。)
  • Balance sheet: asset & accumulated depreciation removed; retained earnings changed via net income.(资产负债表:资产与累计折旧减少,通过留存收益反映净利润变化。)
  • Cash flow statement: cash proceeds under investing activities.(现金流量表:处置收入列入投资活动现金流入。)

6.3 Example-Based Understanding(例题强化理解)

  • Textbook examples: calculate updated depreciation, book value at disposal, gain/loss.(通过教材例题:先补提折旧,再算处置时账面价值和处置损益。)
  • Practice: compare different scenarios (dispose early vs late, high vs low residual).(练习比较不同处置时间和不同残值估计对损益的影响。)
