Creative Cash Flow Reporting — Mulford & Comiskey: COMPLETE

Know the authors before you learn the method, because the background explains the question. Charles W. Mulford and Eugene E. Comiskey were professors of financial reporting at Georgia Institute of Technology and also ran the university's Financial Analysis Lab — a research environment that systematically examined how American companies presented their financial reports. Together they wrote Financial Warnings (1996) on early signals before financial failures, and The Financial Numbers Game (2002) — a catalogue of creative accounting in general.

Their cash flow book, Creative Cash Flow Reporting with the subtitle Uncovering Sustainable Financial Performance (Wiley), is the logical third act: after cataloguing the tricks of earnings they turn their gaze to the statement the market after all considered true — the cash flow statement. The book's very first chapter is called Seeking Sustainable Cash Flow, and there lies the whole programme: not how large the cash flow is, but how much of it repeats next year.

The times shaped the book. Enron fell in 2001, WorldCom in 2002 — and WorldCom is this course's founding case, for one very specific reason. WorldCom deceived not primarily through invented revenue but through classification: operating costs for the network ('line costs') were capitalized as investments instead of being charged against ongoing operations. The effect was double — earnings were inflated AND operating cash flow was inflated, because the outlays were moved to the investing section.

Millions of investors who proudly 'checked cash flow instead of earnings' were deceived on both lines at once. It is against this background that Mulford and Comiskey write: the market's newly won faith in the cash flow statement as a universal remedy was half deserved and half dangerous — deserved because cash is harder to falsify than accruals, dangerous because the cash flow statement is a constructed report with classification choices, timing games and definitional choices on every line.

Place the book in the canon, because the differentiation is the course's foundation. Thornton O'Glove (Quality of Earnings, 1987) taught the reader the craft of the income statement: never read earnings without cash flow and the notes to the accounts. Howard Schilit (Financial Shenanigans, 1993) catalogued every template of earnings manipulation — inflow of revenue, cost games, one-off items. Mulford and Comiskey pose a third question the others only touch in passing: is the CASH genuine? Their unique contribution is treating operating cash flow as a manipulable object in its own right: receivables that are sold instead of collected, suppliers paid late instead of on time, one-offs landing in the operating bucket, costs capitalized out of it, and capex starved so that free cash can flow.

One sentence captures the difference: Schilit asks how the earnings were painted; Mulford and Comiskey ask how the cash flow was painted.

The book's method in compression — it becomes the course's backbone. Step one: read the structure of the cash flow statement and understand that it is derived (chapter 2). Step two: identify what is not recurring — one-off items, securitization effects, classification moves (chapters 6-9). Step three: recalculate — reclassify inconsistently classified items, clean out one-offs, normalize capex to maintenance level (chapter 11).

Step four: compute sustainable cash flow and sustainable free cash, and set it against the dividend, debt and share issue needs (chapter 13). For AKM1 the step to the ecosystem is short: V19 — capital burn and issue risk, the variable that carries the weight CRITICAL — is in practice this method converted into a variable. Whoever masters this book masters the basis of V19; whoever only glances at an OCF line masters nothing.

The cash flow statement divides all movements of money into three buckets: cash flow from operating activities (OCF — what the core business generates), from investing activities (purchases and sales of assets, acquisitions) and from financing activities (loans, amortizations, share issues, dividends, share buybacks). In Swedish groups the division is governed by IAS 7, in individual companies by K3 — and the whole idea, of course, is that the reader should be able to see how the business is financed and what remains for the owners.

But note the decisive point: the buckets are not given by nature. The same physical movement of money can in many cases be reported in more than one bucket depending on judgements and choices — and every boundary line is a place where a skilled auditor or a strong-willed CFO can move millions. The book's third chapter is devoted to exactly this boundary question — Is It Operating or Investing Cash Flow? — and the answer is often: the company decides, within the limits of the standard.

Swedish companies use almost exclusively the indirect method: the cash flow statement begins with the year's result, adds back non-cash items (depreciation, impairments, realized gains and losses adjusted out), and then adjusts for changes in working capital — accounts receivable, inventory, accounts payable and other items. Only then does the cash flow from operating activities appear. This is the chapter's most important single insight: the OCF line is not the bank account — it is a calculation that begins in the manipulable earnings and is then inherited through equally interpretable working capital lines.

Earnings can be prettied upward (Schilit) and the prettiness is then inherited into the starting point of the cash flow calculation. The working capital lines can be prettied in time (chapters 6-7) without a single krona being wrong. The cash movement as FACT exists only in its entirety — the sum of the three buckets — while the distribution between the buckets is accounting policy.

IAS 7 also contains open choices, and two of them concern Swedish listed companies directly. The interest rate PAID may be reported either in operating activities or in financing activities. Interest RECEIVED likewise. Two otherwise identical companies can thus report two different values for operating cash flow solely depending on the choice of principle — and companies that switch principle between years can distort their OCF trend without anything having happened in the business. Paid tax should under the main rule be placed in operating activities, but the distribution between items can be hard to survey.

A worked example showing the mechanics: a company with an interest expense of 40 Mkr; company A classifies it in financing (OCF unaffected), company B in operating activities (OCF minus 40 Mkr). Whose OCF is 'right'? Both — and neither is comparable without adjustment. Practical rule: always find out where the company classifies interest (note 1 or the cash flow note) and normalize to the same principle before you compare companies or years.

Now build the basic discipline of reading — reading a cash flow statement in six steps, top to bottom. (1) The starting point: is it result after tax, and does it contain distorting items that should be cleaned out (chapter 8)? (2) The add-back items: depreciation — do they match the note on non-current assets? (3) The working capital lines: change in accounts receivable, inventory, accounts payable — are they growing in step with revenue (V01), and are there signs of invoice sales or payment stretching? (4) Capex in the investing bucket: how much is maintenance and how much growth? (5) The financing bucket: share issues, new debt, dividend — who financed the year's cash? (6) The check: sum the three buckets and reconcile against the change in cash and cash equivalents — if it does not match, keep reading until you understand why.

Six steps, fifteen minutes — and you hold the map of every manipulation door that the rest of the course opens.
