Issuing debt increases cash and debt at inception; it does not create revenue or profit. Interest affects earnings later. The common interview mistake is combining those two moments without stating the time period.
Date one: receive the loan
Assume a company borrows $100 at par, receives all proceeds in cash, and pays no fees. Ignore any interest accrued on the issuance date. This is a fictional teaching example.
| Statement | Incremental effect at issuance |
|---|---|
| Income statement | No change |
| Cash flow statement | Financing cash inflow of $100 |
| Balance sheet | Cash rises $100; debt rises $100; equity is unchanged |
The balance sheet balances because assets and liabilities rise by the same amount. Do not record the borrowing as operating cash flow. The SEC’s financial-statement guide explains the separation of operating, investing and financing cash flows.
Date two: pay one year of interest
Now assume 10% annual interest, no principal repayment, a 25% marginal tax rate, immediate use of the interest tax deduction, and interest paid in cash at year-end. Use US GAAP operating classification for interest paid in this simplified example.
Interest expense is $10. Tax expense falls $2.50 relative to the otherwise identical unlevered case, so net income falls $7.50. With cash taxes reduced immediately and no other changes, operating cash flow falls $7.50. Cash and retained earnings each decline $7.50 relative to the issuance-date position; debt remains unchanged.
Measured across both events, cash is up $92.50, debt is up $100 and equity is down $7.50. The check is $92.50 = $100 − $7.50.
Answer the follow-up before reaching for a formula
What if the company cannot use the tax deduction immediately? The $2.50 immediate cash-tax saving is no longer justified. Separate cash taxes from any deferred-tax accounting; do not blindly multiply by one minus the tax rate.
What if there is an issuance fee? Cash proceeds and the accounting carrying amount may differ from face value, and effective interest can differ from the coupon. Ask how the question treats fees instead of reusing the no-fee answer.
What if interest is paid in kind? Cash payment is different from accrual. Explain the debt increase and interest expense under the given assumptions; use the PIK worked example for a separate drill.
A concise spoken answer
“At issuance, cash and debt each increase by $100 with no income-statement effect, assuming no fees. Over the following year, $10 of cash interest reduces net income by $7.50 if the 25% tax benefit is immediately usable. I would confirm the reporting framework and tax assumptions before extending the example.”
Use the accounting interview guide for the foundation, then compare this cash borrowing with a noncash goodwill impairment. The distinction is the economic event, not a memorized three-statement script.
