使用原書 Cash Flow Before Debt Paydown、minimum cash cushion 與 interest-income analysis,建立 debt action 前真正可用的現金。
原書先排除 Short-Term/Long-Term borrowings and repayments、finance lease principal repayments、financing obligations principal repayments,得到 Cash Flow Before Debt Paydown。Minimum Cash Cushion 設為 40,000。另由 securities fair value/interest information 推導 implied interest-income rate 0.49%。
| 項目 | 2021E | 2022E | 2023E | 2024E | 2025E |
|---|---|---|---|---|---|
| Cash at Beginning | 42,122.0 | 49,734.8 | 63,170.9 | 88,193.1 | 102,354.8 |
| Cash Flow Before Debt Paydown | 7,612.8 | 13,436.1 | 25,022.2 | 14,161.7 | 25,752.1 |
| Minimum Cash Cushion | (40,000) | (40,000) | (40,000) | (40,000) | (40,000) |
Cash Available for Debt Paydown = Beginning Cash + Cash Flow Before Debt Paydown − Minimum Cash Cushion。Interest Income = AVERAGE(Beginning Cash, Ending Cash) × 0.49%。原書在 Cash Flow Statement 用 =G22+G30+G37 的邏輯得到 pre-debt-paydown cash flow。
| 項目 | 2021E | 2022E | 2023E | 2024E | 2025E |
|---|---|---|---|---|---|
| Total Cash Available | 9,734.8 | 23,170.9 | 48,193.1 | 62,354.8 | 88,106.8 |
| Interest Income | 225.0 | 276.6 | 370.8 | 466.8 | 564.6 |
| Estimated Interest Rate | 0.49% | 0.49% | 0.49% | 0.49% | 0.49% |
Cash Flow Before Debt Paydown 刻意排除 debt issuance/retirement,才能回答「在任何新的 debt action 前,公司本身產生多少可用 cash」。Minimum cash cushion 則避免模型把所有 cash 都拿去還債。Interest income 又會反過來提高 Net Income/Cash,形成 circular reference。
請根據 2021E–2025E Beginning Cash、Cash Flow Before Debt Paydown、40,000 minimum cash 與 0.49% rate,說明 Cash Available 與 Interest Income 如何互相連動,以及為什麼 debt issuance/retirement 必須先排除。
**問題:**若 2021E Minimum Cash Cushion 提高到 45,000,其他數字不變,Total Cash Available 為多少?
