Howard Schilit's Financial Shenanigans (with Jeremy Perler and Yoni Engelhart, 4th ed.) is the forensic literature's standard survey of earnings manipulation, and everything that follows is taught in his debt. His book sorts the tricks one way and we sort them another. A working analyst doesn't meet a shenanigan pre-labelled. You meet a line that looks wrong, and you have to ask what kind of lie could produce it.
So we sort by what the lie does to the accounts. That's also the order in which you'll suspect things when you read a filing. Three families, seven moves.
Two further weapon classes wait for you in Shenanigans II. The cash-flow games fill its sections 4.3 to 4.8, and the key-metric and acquisition-accounting games are its section 4.15.
What are the types of financial shenanigans?
Family 1: lies about revenue. The top line is the first thing a manager under pressure reaches for, because everything below it inherits the error.

- Revenue too soon. The sale is real but the period is wrong. Tomorrow's revenue is booked today.
- Revenue that isn't. Not a sale at all: no economic substance, not at arm's length, or a pass-through grossed up into revenue that was never the company's to record.
- Windfall as operations. The gain is real but it is not the business. A one-time or unsustainable item is dressed up as ordinary operating income.
Family 2: lies about cost. If the top line cannot be stretched further, the costs beneath it can be moved or made to disappear.
- Cost parked. A real cost is refused as an expense and parked on the balance sheet as an "asset" instead. It gets capitalised, deferred or buried in inventory.
- Cost hidden. A real cost is never recorded at all, or is smothered by releasing a reserve set aside in a better year.
Family 3: lies about which period. These two run the other way, which makes them easy to miss. Management understates profit on purpose.
- Profit in a jar. Today's income is hidden away for a rainy quarter. It's the smoothing tool of a company having a year that's too good.
- The big bath. Tomorrow's costs are dumped into today, so that tomorrow smiles. The favourite of an arriving chief executive, who gets one free chance to blame a predecessor.
The first five inflate current earnings and the last two deflate them deliberately. Together they let management move profit along the time axis almost at will. For a while, anyway.
How do you detect financial shenanigans?
The master law: every earnings lie must live on the balance sheet. It follows from double-entry, which you've owned since your first journal entries. Credit revenue that shouldn't exist and you must debit something: receivables, unbilled contract assets, cash routed in a circle. Refuse to debit an expense and the cost sits as an asset (PP&E, CWIP, capitalized "development," inventory) or as a missing liability. The income statement is a flow that vanishes into retained earnings each year; the balance sheet is the sediment, and sediment accumulates.
So every detection test you'll learn this week comes down to a balance-sheet account scaled by the P&L line it feeds: receivables versus revenue, CWIP versus gross block, provisions versus sales. The P&L tells you the story management wants told. The balance sheet keeps the receipts.
The second law: accruals reverse, so manipulation escalates. Pull ₹100 crore of next year's revenue into this year and next year starts ₹100 crore in the hole and must still grow. Now the game needs ₹210 crore to show the same trend. This is the treadmill: cut-off games become channel stuffing, channel stuffing becomes fictitious invoices. It has two implications. First, small aggressions are leading indicators of big ones, so take them seriously. Second, manipulated growth has a signature shape: an acceleration that outruns cash collections, then a sudden "industry slowdown" or "one-time correction" when the treadmill jams (you'll compute this shape yourself in Worked Example 2).
How to read the families. Each family gets the same five-part block: the move (what management does), the entries (the debits and credits that create it), the residue (where it shows on the statements), the tests (the specific ratio, note, or trend), and on the record (a named real case, stated carefully). Read with a pencil. The practice set will hand you eight mini-filings and expect the blocks to fire automatically.
