The DCF method discussed earlier involved free cash flows obtained from financial statements and reports of a publicly held company, and discounted with a rate appropriate for the risk in the situation. In general, DCF methods are based on future cash flows, which, of course, are inherently uncertain.That uncertainty helps determine the discount rate used in the traditional cash flow approach.
Financial Accounting Standards Board (FASB) Concepts Statement No. 7 presents an alternative to the traditional cash flow (TCF) approach. The process put forth by the FASB can be used for measurement at initial recognition or fresh-start measurements. It allows for uncertainty, not in the discount rate (as in the traditional method), but in the cash flows.
Instead of definite cash flows, the expected cash flow (ECF) approach uses a set of possible cash flows, along with their probabilities. Exhibit 7.6 compares the two methods that one can use to compute a present value. The objective for both methods is to obtain a market value of an asset or liability.
In the TCF approach, the uncertainty affects the discount rate. In the ECF approach, the uncertainty affects the cash flow. One of the uses of the ECF approach is for fresh-start measurements when it is necessary to determine a new carrying value unrelated to whatever amount is currently recorded.
Exhibit 7.7 shows a comparison for a hypothetical example of an asset that will produce a cash flow of $10,000 at the end of year 1 and $10,000 at the end of year 2.
