Anonymised, illustrative composite. A Manitoba industrial-parts distributor never wrote a dollar of obsolete inventory down — not on its books, and not on the tax return the Income Tax Act required it to file that way.
At a glance
A Winnipeg family holding company was selling 100% of the shares of Northgate Fasteners & Supply Ltd., a Manitoba industrial-parts distributor that had stocked bearings, seals, gaskets and fasteners for regional manufacturers for twenty-two years. The share purchase agreement priced the business off a working-capital target built from the vendor's year-end financial statements, in which inventory of $1,850,000 was carried at cost, unchanged in presentation for as long as anyone on the buyer's deal team could find prior statements.
The buyer ordered an inventory count and an aging report as a closing condition — not unusual, but the report this time came back with a column nobody had asked for: last-movement date by SKU.
$620,000 of the $1,850,000 — roughly a third of the book figure — had not moved in eight to fourteen years. Most of it was stock for machinery lines the original manufacturers had discontinued; a smaller portion was seasonal overbuys the company had simply never cleared. Every dollar of it sat on the balance sheet, and on the tax return, at the price Northgate had originally paid.
Asked when the company had last written any of it down, the controller's answer was not that I can recall. That was the tell, but it was also, on its own terms, a compliance gap: valuing inventory is not a bookkeeping preference under the Income Tax Act, it is a computation the Act requires every year.
Purchase price $4,200,000 on a debt-free, cash-free basis, working capital target $1,240,000 built off the trailing balance sheet. An equipment and inventory appraiser retained by the buyer valued the $620,000 slow-moving tranche at $95,000 on a forced-liquidation basis — scrap and salvage-buyer pricing for parts nobody stocks a machine to use any more. The gap between book and appraised value, $525,000, was larger than the entire indemnity holdback the parties had discussed to that point.
Section 10(1) of the Income Tax Act does not leave inventory valuation to the taxpayer's discretion. It requires that inventory “shall be valued at the end of the year at the cost at which the taxpayer acquired the property or its fair market value at the end of the year, whichever is lower.” Whichever is lower — not whichever the company has always used. A business that never writes obsolete stock down to fair market value has, in every year that gap existed, computed its income on the wrong number.
The instinct on the buyer's side was to reach for section 10(4), which supplies a fair-market-value formula for two categories of inventory: a profession's work in progress, and materials and supplies. It does not reach this file. The subsection's own opening words carve its formula out of anything “obsolete, damaged or defective” before the formula even starts — the fair-market-value definitions in paragraphs (a) and (b) of s.10(4) apply only to property other than obsolete, damaged or defective property. For genuinely obsolete stock, the Act supplies no plug-in number. Fair market value takes its ordinary, undefined meaning, which is why the parties needed an appraiser rather than a formula.
That has a second consequence past the price negotiation. A write-down under s.10(1) is a deduction in computing income for the year it is taken — and nobody had taken it. In a share purchase, the buyer acquires the corporation with that unclaimed position still sitting in its history; whichever party ends up filing the target's pre-closing and post-closing tax returns is the one that decides, and benefits from, when that deduction is finally recognized.
The purchase price was reduced by $525,000 to reflect the appraised value, and the working-capital target was rebuilt using the appraiser's figure rather than book cost. The vendor's closing representations were amended to state that inventory had been valued in accordance with s.10(1) as at the closing balance sheet — not merely that the count was accurate — and the pre-closing corporate tax return, which the vendor remained responsible for filing under the agreement's tax covenants, was required to reflect the write-down rather than defer it into the buyer's hands.
Closing on the unadjusted numbers would have overpaid for $525,000 of parts a scrap buyer would not have paid book value for, and it would have handed the buyer a corporation whose historical tax filings understated a deduction it was entitled to — a position that is awkward, not free, to correct after the fact.
The aging report, not the balance sheet, was what surfaced it. A book value that has not moved for over a decade is not evidence of stability; it is evidence that nobody has looked.
