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.

Chapters 1, 3 and 12
Reported cash by location, and the four subtractions that take it from 214,000,000 to 205,000,000, to 152,000,000 under the facility’s definition, to 120,608,000 once six days of the company’s own payments are held back, to the 68,400,000 cleared on the concentration account this morning. The float is a cell: set it to four days or eight and watch reading 4 move by 10,464,000 each way.
Then net debt three ways on the same 550,000,000: 2.0000x on the board’s cash, 2.3690x on the facility’s, 2.5559x on the treasurer’s, with the headroom under the covenant beside each. The cash definition alone is 0.3690 turns, and it is a formula.
Chapters 4, 5, 6 and 7
Twelve quarterly forecast errors and the standard deviation they produce — 4.1026 per cent of quarterly disbursements, 13,415,426.12 — then the reserve at 95, 99 and 99.9 per cent, and the minimum liquidity from its three components: 124,596,281.16, of which 93,204,281.16 sits above the float. The headroom is tested on both consistent bases, and the classic double count that says the company is 3,988,281.16 short is reproduced on the page and labelled as the error it is.
The drawstop, solved: the EBITDA at which the covenant is exactly met on the facility’s cash, 132,666,666.67, a fall of 21.0317 per cent, and at an operating leverage of 2.5 a fall in annual revenue of 8.4127 per cent. Without the revolver the company clears its own minimum by 27,403,718.84 — 5.2377 days of payments. Then three ways to hold 250,000,000, priced — 1,562,500 undrawn, 5,625,000 as term debt on deposit, 5,000,000 drawn — the 4,062,500 premium for liquidity without a drawstop, and the cover under each way on both readings of finance charges.
Chapters 8, 9, 10 and 11
Eighty days of cash conversion cycle turned into money: a day of receivables is worth 3,835,616.44 and a day of payables 2,684,931.51, and five days off DSO releases 19,178,082.19 without a bank. The 2/10 net 60 discount annualised — 14.8980 per cent — and netted against the cost of funding fifty days on the revolver: 5,471,890.41 a year, and the 0.3132 turns of reported leverage it costs.
The supply chain finance programme on the annual-flow basis: 66,049,315.07 released, the supplier’s saving of 5,541,698.63 against 90-day terms and its cost of 72,493.15 against the terms it actually has, and the reclassification on both readings — 2.7622x on the extension, 3.1362x on the balance the bank holds. And the eurozone pool before and after: 1,190,000 a year.
Chapters 13 and 14
The swap: interest of 26,547,500 and cover of 6.3283x today, 32,187,500 against 28,947,500 after a 200 basis point rise, the saving of 3,240,000 that nine years of carry buy — and the shortcut that says 3,600,000, reproduced and labelled. The base rate at which cover reaches 4.00x, with and without the swap: 8.27 and 15.88 per cent. The fixed share on both readings, and the net floating exposure after cash.
The currency hedge: the forward from the two rates, 1.095728, the carry of 1,594,896.33 that is an interest differential and not a fee, three futures for the spot with the hedge gain in each — the hedge that lost 8,130,844.04 at 1.0200 and was right — the value of one cent (1,019,367.99) and ten, and the layered programme.

| Checks sheet | the printed figure beside the computed one, with a PASS or a FAIL |
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.
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.
