# Amortization Schedules

Create accurate amortization schedules for loans, intangible assets, deferred costs, and financial instruments using appropriate amortization methods aligned with accounting standards and business objectives.

## Workflow

1. **Classify Amortization Type and Select Method**
   - Determine the correct amortization approach:
     ```
     AMORTIZATION TYPE AND METHOD SELECTION
     ════════════════════════════════════════
     
     Type 1: Debt / Loan Amortization
       → Purpose: Track principal and interest payments over loan life
       → Method: Effective interest method (standard)
       → Standards: ASC 470, IFRS 9
       → Output: Monthly amortization table with principal, interest, balance
     
     Type 2: Intangible Asset Amortization
       → Purpose: Systematically allocate cost of finite-life intangible assets
       → Method: Straight-line (default) or pattern-of-benefit (if determinable)
       → Standards: ASC 350, IAS 38
       → Output: Annual/monthly amortization expense schedule
     
     Type 3: Deferred Cost Amortization
       → Purpose: Recognize capitalized costs as expense over benefit period
       → Examples: Deferred financing costs, prepaid expenses, CAC
       → Method: Straight-line (most common) or proportional
       → Standards: ASC 340-10, ASC 835-30
     
     Type 4: Bond Premium / Discount Amortization
       → Purpose: Adjust carrying value of bond to face value at maturity
       → Method: Effective interest method (required)
       → Standards: ASC 470-10, IAS 39
       → Output: Periodic amortization amount and carrying value
     
     Type 5: Deferred Revenue Recognition
       → Purpose: Recognize revenue over contract performance period
       → Method: Straight-line or usage-based
       → Standards: ASC 606, IFRS 15
       → Output: Monthly revenue recognition schedule
     ```

2. **Build Loan Amortization Schedule**
   - Create comprehensive loan amortization table:
     ```
     LOAN AMORTIZATION SCHEDULE
     ════════════════════════════════════════
     
     Loan Parameters:
       → Principal: $500,000
       → Annual Interest Rate: 6.5%
       → Term: 60 months (5 years)
       → Payment Frequency: Monthly
       → First Payment Date: 2025-02-01
     
     Monthly Payment Calculation:
       → Monthly rate: 6.5% / 12 = 0.5417%
       → Monthly payment = P × [r(1+r)^n] / [(1+r)^n - 1]
       → Monthly payment = $500,000 × [0.005417(1.005417)^60] / [(1.005417)^60 - 1]
       → Monthly payment = $9,764.73
     
     ════════════════════════════════════════
     Month | Payment  | Principal | Interest | Remaining Balance
     ──────┼──────────┼───────────┼──────────┼──────────────────
     1     | $9,765   | $7,117    | $2,648   | $492,883
     2     | $9,765   | $7,155    | $2,610   | $485,728
     3     | $9,765   | $7,193    | $2,572   | $478,535
     ...   | ...      | ...       | ...      | ...
     59    | $9,765   | $9,713    | $52      | $9,713
     60    | $9,765   | $9,713    | $52      | $0
     
     Totals:
       → Total payments: $585,884
       → Total principal: $500,000
       → Total interest: $85,884
       → Interest as % of total: 14.66%
     ```
   - Handle special loan features:
     ```
     SPECIAL LOAN FEATURES
     ════════════════════════════════════════
     
     Balloon Payment:
       → Regular monthly payment calculated on shorter amortization (e.g., 360 months)
       → Loan matures in shorter term (e.g., 60 months)
       → Balloon = Remaining principal at maturity
     
     Interest-Only Period:
       → First N months: Payment = Interest only
       → After N months: Full amortization on remaining principal
       → Extend term or recalculate payment
     
     Variable Rate (Adjustable Rate Mortgage):
       → Recalculate payment at each rate adjustment
       → Cap on periodic and lifetime rate increases
       → Disclose payment increase scenarios
     
     Bi-Weekly Payments:
       → Payment = Monthly payment / 2
       → 26 payments/year = 13 monthly payments worth
       → Accelerates payoff by ~3-4 years
       → Reduces total interest by ~20-30%
     
     Extra / Prepayments:
       → Apply to principal (reduces balance)
       → Recalculate subsequent interest
       → Track total prepayment amount and interest savings
     ```

3. **Build Intangible Asset Amortization Schedule**
   - Amortize finite-life intangible assets:
     ```
     INTANGIBLE ASSET AMORTIZATION
     ════════════════════════════════════════
     
     Asset: Customer Relationship (acquired in business combination)
       → Acquisition cost: $2,000,000
       → Useful life: 5 years (based on customer attrition analysis)
       → Residual value: $0
       → Amortization method: Straight-line
       → Annual amortization: $2,000,000 / 5 = $400,000
       → Monthly amortization: $400,000 / 12 = $33,333
     
     Asset: Technology / Patent
       → Acquisition cost: $800,000
       → Useful life: 8 years
       → Method: Declining balance (2x) — reflects front-loaded economic benefit
       → Year 1: $800,000 × (2/8) = $200,000 (25%)
       → Year 2: ($800,000 - $200,000) × 25% = $150,000
       → Year 3: ($600,000 - $150,000) × 25% = $112,500
       → ...
     
     Asset: Tradename / Brand
       → Acquisition cost: $1,500,000
       → Useful life: INDEFINITE (not amortized)
       → Annual impairment test required (ASC 350)
       → Amortization: $0 (test for impairment instead)
     
     AMORTIZATION CALENDAR (Monthly)
     ════════════════════════════════════════
     Month    | Customer Rel | Technology  | Total Amortization
     ─────────┼──────────────┼─────────────┼───────────────────
     Jan      | $33,333      | $16,667     | $50,000
     Feb      | $33,333      | $16,667     | $50,000
     ...      | ...          | ...         | ...
     Dec      | $33,333      | $16,667     | $50,000
     
     Accumulated Amortization (end of Year 1): $600,000
     Net Book Value (end of Year 1): $2,200,000
     ```

4. **Build Deferred Cost Amortization Schedule**
   - Amortize capitalized costs:
     ```
     DEFERRED COST AMORTIZATION
     ════════════════════════════════════════
     
     Deferred Financing Costs:
       → Legal fees, underwriting, arrangement fees: $150,000
       → Related loan term: 5 years (60 months)
       → Amortization method: Effective interest method (align with debt)
       → Or: Straight-line if not materially different
       → Monthly: $150,000 / 60 = $2,500
       → Present as reduction of interest expense (contra-expense)
       → Balance sheet: Other assets (current and non-current portions)
     
     Capitalized Customer Acquisition Cost (CAC):
       → Sales commissions capitalized: $500,000
       → Customer contract term: 3 years (36 months)
       → Amortization: $500,000 / 36 = $13,889/month
       → Standard: ASC 340-40 (revenue contracts)
       → Amortize over period of benefit (contract term + renewal periods if probable)
     
     Prepaid Expenses:
       → Annual insurance premium: $120,000 (paid Jan 1)
       → Amortization: $120,000 / 12 = $10,000/month
       → Balance sheet: Prepaid expense (current asset)
     
     Journal Entry (Monthly):
       DR Amortization Expense                  $13,889
       CR Deferred Cost / Capitalized CAC       $13,889
     ```

5. **Build Bond Premium / Discount Amortization**
   - Amortize bond differences using effective interest method:
     ```
     BOND PREMIUM / DISCOUNT AMORTIZATION
     ════════════════════════════════════════
     
     Scenario: Company issues $1,000,000 bond at 95 (discount)
       → Face value: $1,000,000
       → Issue price: $950,000 (95% of face)
       → Coupon rate: 5% (stated rate on bond)
       → Market rate: 6% (effective rate at issuance)
       → Term: 5 years, semi-annual payments
       → Discount to amortize: $50,000
     
     Semi-annual coupon payment: $1,000,000 × 5% × 6/12 = $25,000
     
     ════════════════════════════════════════
     Period | Carrying Value | Interest Expense | Cash Paid | Amortization | New CV
     ───────┼────────────────┼──────────────────┼───────────┼──────────────┼─────────
     0      | $950,000       | —                | —         | —            | $950,000
     1      | $950,000       | $28,500          | $25,000   | $3,500       | $953,500
     2      | $953,500       | $28,605          | $25,000   | $3,605       | $957,105
     3      | $957,105       | $28,713          | $25,000   | $3,713       | $960,818
     ...    | ...            | ...              | ...       | ...          | ...
     10     | $996,339       | $29,891          | $25,000   | $4,891       | $1,000,000
     
     Interest expense = Carrying value × market rate × period
     Amortization = Interest expense - Cash paid
     New CV = Prior CV + Amortization (for discount)
     
     At maturity: Carrying value = Face value ($1,000,000) ✓
     ```

6. **Validate and Reconcile Amortization Schedules**
   - Ensure accuracy and compliance:
     ```
     AMORTIZATION VALIDATION CHECKLIST
     ════════════════════════════════════════
     
     → Total amortized = Original amount (or original - residual value)
     → Final balance = $0 (for fully amortized items) or residual value
     → Monthly/periodic amounts are consistent with selected method
     → Amortization period aligns with economic life (not arbitrary)
     → Impairment review performed if carrying value > recoverable amount
     → Changes in useful life accounted for (prospective adjustment)
     → Disclosure in financial statement notes:
       · Gross carrying amount
       · Accumulated amortization
       · Amortization expense for the period
       · Remaining useful life by asset category
       · Material assumptions in useful life estimation
     ```

7. **Handle Mid-Period and Change-in-Circumstance Adjustments**
   - Manage schedule modifications:
     ```
     MID-PERIOD AND CHANGE ADJUSTMENTS
     ════════════════════════════════════════
     
     New Asset Mid-Period:
       → Prorate first month: Full monthly amount × (days remaining / days in month)
       → Or: Half-year convention (tax) / mid-month convention
     
     Early Loan Payoff:
       → Calculate remaining principal at payoff date
       → Prepayment penalty (if applicable per loan agreement)
       → Write off unamortized deferred financing costs
       → Record gain/loss on extinguishment:
         Gain/Loss = Carrying value of debt - Payoff amount
     
     Change in Useful Life (Intangible Assets):
       → Prospective adjustment (no restatement)
       → New monthly amortization = Remaining book value / Remaining months
       → Document reason for change
     
     Impairment of Amortized Asset:
       → Test: Carrying value > Recoverable amount (higher of FV-costs-to-sell or value-in-use)
       → If impaired: Write down to recoverable amount
       → Amortize reduced carrying value over remaining life
       → Impairment loss is separate from regular amortization
     ```

## Edge Cases & Handling

```
EDGE CASES
═══════════════════════════════════════

1. Indefinite-Life Intangible Assets
   → NOT amortized (trademarks, goodwill, some patents)
   → Annual impairment testing required
   → If life becomes finite: Begin amortization prospectively

2. Loan Restructuring / Modification
   → Evaluate as troubled debt restructuring (TDR) vs. non-TDR modification
   → If TDR: Recalculate effective rate, recognize loss
   → If not TDR: Continue with modified terms, adjust schedule prospectively

3. Multiple Currency Amortization
   → Amortize in functional currency
   → Translate at appropriate rate (spot for BS, average for IS)
   → Record FX gain/loss on monetary items

4. Acquisition-Dated Amortization (Purchase Price Allocation)
   → Intangibles identified in PPA amortized from acquisition date
   → Not from original creation date
   → Useful life based on remaining economic life at acquisition
```

## Conversation Examples

### Loan Amortization Request
```
User: "We're taking a $2M term loan at 7.25% for 7 years. Can you build the amortization schedule and tell me the payment?"
AI: "Here's your loan amortization:

Loan Parameters:
→ Principal: $2,000,000
→ Rate: 7.25% annual
→ Term: 84 months (7 years)
→ Monthly payment: $28,697

Summary:
→ Total payments: $2,410,589
→ Total interest: $410,589
→ Interest as % of total: 17.0%

Year-by-Year Breakdown:
Year 1: Principal $254,632 | Interest $95,553 | End balance $1,745,368
Year 2: Principal $273,405 | Interest $76,780 | End balance $1,471,963
Year 3: Principal $293,673 | Interest $56,512 | End balance $1,178,290
Year 4: Principal $315,525 | Interest $34,660 | End balance $862,765
Year 5: Principal $339,074 | Interest $11,111 | End balance $523,691
Year 6: Principal $364,478 | Interest ($14,293)* | End balance $159,213
Year 7: Principal $159,213 | Interest ($35,577)* | End balance $0

*Negative interest shown means principal pays down faster than equal-payment baseline

Cash flow impact: $28,697/month from operating cash flow
Debt service coverage: Need EBITDA > $28,697 × 12 / DSCR requirement (typically 1.25x)
→ Required annual EBITDA: > $431,000

Want me to model scenarios with balloon payment, bi-weekly, or extra payments?"
```

### Intangible Asset Amortization
```
User: "We acquired a company and the PPA identified $5M in customer relationships, $2M in technology, and $1M in tradename. How do we amortize these?"
AI: "Here's your PPA intangible asset amortization plan:

1. Customer Relationships ($5M):
   → Useful life: 5-7 years (based on customer attrition analysis)
   → Method: Straight-line
   → Annual amortization: ~$714K-$1,000K
   → DR Amortization Expense, CR Accumulated Amortization

2. Technology / Patents ($2M):
   → Useful life: 8-10 years (tech lifecycle, legal protection period)
   → Method: Declining balance (2x) if front-loaded benefit, otherwise straight-line
   → Annual amortization (SL): $200K-$250K
   → Accelerated method front-loads expense

3. Tradename / Brand ($1M):
   → Assessment: Indefinite life vs. finite life
   → If indefinite: NOT amortized (annual impairment test only)
   → If finite (e.g., market-specific, declining brand): 10-15 year life
   → Annual amortization (if 10yr): $100K

Impact on P&L:
→ Year 1 total amortization: $914K-$1,250K (depending on tradename assessment)
→ This is ABOVE operating income (reduces reported profit)
→ But it's a non-cash expense (add back for cash flow, EBITDA)

Key considerations:
→ Tax deduction: Amortization is generally tax-deductible (Section 197)
→ Financial reporting: Disclose useful life assumptions and methodology
→ Audit: Be prepared to defend useful life estimates with market data
