Which of the following statements is CORRECT? a. Most rapidly growing companies have positive free cash flows because cash flows from existing operations will exceed fixed assets and working capital needed to support the growth. b. In finance, we are generally more interested in cash flows than in accounting profits. Free cash flow (FCF) is calculated as after-tax operating income plus depreciation less the sum of capital expenditures and the change in net operating working capital. Free cash flow is the amount of cash that could be withdrawn without harming the firm's ability to operate and to produce future cash flows. c. The first major section of a typical statement of cash flows is "Operating Activities," and the first entry in this section is "Net Income." Then, also in the first section, we show some items that add to or subtract from cash, and the last entry is called "Net Cash Provided by Operating Activities." This number can be either positive or negative, but if it is negative, the firm is almost certain to soon go bankrupt. d. An increase in accounts receivable is added to net income in the operating activities section because if accounts receivable increase, then when they are collected cash will come into the firm. e. The next-to-last line on the income statement shows the firm's earnings, while the last line shows the dividends the company paid. Therefore, the dividends are frequently called "the bottom line."
