Treasury Management

A Practitioner’s Guide to One Company, Five Cash Balances, and the Liquidity That Disappears the Day It Is Needed

These are the four Excel workbooks that go with the book. Every figure the book prints is reproduced in them by a live formula rather than a typed constant — change the days of float, the covenant, the supplier’s own funding rate or the spot in twelve months, and every dependent number moves. Each one ends with a Checks sheet setting the printed figure beside the computed one: 116 controls in all, every one green. If a control ever reads FAIL, the workbook is wrong, not the book.

Why the checks matter more than the models

A workbook that agrees with a book proves nothing on its own — the author wrote both. What the Checks sheets do is different: they force the model to reproduce a number that was printed before the model existed, from a formula rather than from the number itself.

On this book the discipline caught three things a reading would not, and each of them changed a conclusion. The first was a double count: the six-day float had been taken out of the cash and put into the requirement at once, and the company was 3,988,281.16 short of its own minimum; counted once, it clears it by 27,403,718.84. The second was a supplier’s cost computed on one turn of the payables stock and printed as a year: the saving was 1,366,446.24 and is 5,541,698.63. The third was the swap’s saving in the shock year, 3,600,000 by comparing two “extra interest” figures from different baselines, 3,240,000 as the difference in total interest. All three wrong figures are still in the workbooks, labelled, because a reader who can see the error is a reader who will not make it.

Where a shortcut and the full computation disagree, both are shown. Interest cover under way B is 5.2627x net of deposit income and 4.3724x gross, and 4.1638x once the overdraft interest the book’s total leaves out is added; the net floating exposure after cash is -608,000, or at most 64,392,000 on home-currency cash alone. Neither gap is smoothed away.

Opening the files

The workbooks open in Microsoft Excel, LibreOffice Calc, Google Sheets and Numbers. They use no macros and no add-ins, so nothing needs to be enabled or trusted. If your spreadsheet asks to update links on opening, decline — there are none.
