Cash Flow Hedge
A cash flow hedge is a designated hedging relationship under ASC 815 in which a derivative is used to offset the variability in cash flows attributable to a particular risk associated with a recognized asset or liability, or a highly probable forecasted transaction, with the effective portion of the hedge gain or loss deferred in other comprehensive income until the hedged item affects earnings.
Cash flow hedges are among the most commonly used hedging strategies at large US corporations. The defining characteristic is that the hedged exposure is cash flow variability rather than fair value changes. A company that expects to purchase jet fuel in six months, for example, faces the risk that jet fuel prices will rise between now and the purchase date. By entering into a commodity futures contract or a commodity swap to lock in a purchase price, the company eliminates (or substantially reduces) the cash flow uncertainty. If the hedge is designated and qualifies under ASC 815, the accounting defers the gain or loss on the derivative in accumulated other comprehensive income (AOCI) on the balance sheet until the actual fuel purchase occurs and is recognized in income.
The mechanics work as follows. At each reporting date, the entire fair value of the derivative is recorded on the balance sheet. The change in fair value is split into an effective portion and an ineffective portion (though under ASU 2017-12 simplifications, separately measuring ineffectiveness is no longer required for qualifying hedges). The effective portion goes to OCI, while the ineffective portion goes directly to current-period earnings. When the hedged transaction — the fuel purchase — occurs, the amount sitting in AOCI is reclassified into earnings in the same line item as the hedged transaction, effectively adjusting the reported cost of the fuel to the locked-in price.
Cash flow hedges can also be applied to variable-rate debt. A company with floating-rate borrowings can enter into an interest rate swap (receive floating, pay fixed) designated as a cash flow hedge of the interest payments on the debt. As market rates fluctuate, the swap's fair value changes are captured in AOCI rather than in earnings, and the swap settlement payments are recognized as interest expense as they occur, converting the effective borrowing rate to the fixed rate of the swap.
Discontinuation of a cash flow hedge occurs when the hedging instrument expires, is sold, terminated, or exercised; when the hedge no longer meets the effectiveness criteria; or when management revokes the designation. If the hedged forecasted transaction is still expected to occur, the amount in AOCI remains there until the transaction affects earnings. If the transaction is no longer probable of occurring, the cumulative AOCI balance is immediately reclassified into earnings — a potentially significant income statement impact.
For investors, the AOCI balance related to cash flow hedges represents a timing difference between economic reality and reported earnings. A company with a large negative AOCI from cash flow hedges has deferred losses that will flow through income when hedged transactions occur, creating a predictable earnings headwind that the notes to the financial statements should disclose.
