Pitfalls in Calculating Cash Flow from Operations.
指出用间接法将营运资金调整为经营活动现金流量的固有困难，说明该方法因概念和实践问题无法等于实际现金流量，最多只是估计值。
Abstract ABSTRACT: Although many firms now prepare a cash-based statement of changes in financial position, reported "funds from operations" is typically a measurement of working capital. The statement reader wishing to determine cash flow from operations must use a series of indirect adjustments to do so. Our purpose in this paper is to identify the inherent difficulties the reader encounters when using this indirect method to convert reported funds from operations to a cash flow amount. We demonstrate how the indirect method will in fact not equal actual cash flow from operations because of numerous conceptual and practical problems encountered when applying the necessary adjustments. We develop illustrations of these problems, and we show how cash flow from operations calculated by the indirect method is, at best, an estimate of actual cash provided by operations.
