The workbook

What to try first

Set both risk weights to 100 per cent — the unregulated fund case — and look again. Then put your own funding spread in. Most lenders discover that the ranking of their last three loans depends more on the capital line than on anything discussed at credit committee, which is precisely the chapter’s argument and much more persuasive as your own numbers.

What the arithmetic does not settle

It cannot tell you the probability of default, which is the input the whole comparison turns on and the one nobody can observe. It cannot price the risk a team is not equipped to manage — the chapter’s sharpest point, and the one no model captures. And capital treatment differs by lender type and jurisdiction, which is why the book avoids naming regimes. The arithmetic holds in any regime; only the inputs change.

The same models, for your own loans

Two workbooks with every input emptied. The checks sheets count what is still missing and test what holds for any inputs.

The documents the chapters describe

Thirteen pages to print and use. A4, with margins wide enough for US Letter.

Forty questions, marked by the file

A workbook that marks itself. Answer in the yellow cells; the marking fills in as you go.

Three cases the book does not work

New material, not a restatement. Three situations the chapters name and never take to a number. Each case is one workbook: the note is the first sheet, the model is the rest, and a checks sheet closes it. Type your own figures in and every finding recomputes.

Conventions used throughout

Amber fillan input — you may edit these
Grey filla formula — do not overtype these
Checks sheettwenty-three controls in the book’s workbook, each stating its own verdict; every other workbook ends with its own
ADDEDa figure the book does not give, used in the cases and marked wherever it appears

Every figure is illustrative, as everything in the book is. The loans, the sponsor, the funding cost and the risk weights are invented. The arithmetic is not.

Opening the files

The workbooks open in Microsoft Excel, LibreOffice Calc, Google Sheets and Numbers; the PDF prints on A4 or US Letter. 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.

What changed, and when

23 Sep 2026The book’s workbook corrected: the early-repayment sheet hard-coded the running cost at 5 basis points instead of the 9 sheet 1 implies, so Loan A returned 34.1 per cent to term there and 33.1 on sheet 2; it is now 33.1 to term and 38.4 repaid at eighteen months, not 34.1 and 39.4. Each 100 basis points of prepayment protection buys about 29 of tolerance, not forty; 13, 41 and 70 were right. Twenty-three checks. Added: a blank version, a sizing and exit-test model, thirteen working documents, forty questions that mark themselves and three new cases. The workbook can now also be downloaded on its own.
