Net-nets screen cheap on NCAV, but low-quality working capital can erase that margin. Treat receivables and inventory as probabilistic, not certain.
Haircut playbook
Receivables: pull aging from filings; haircut 10-30 percent if 60-90 days, 50 percent if 90 days plus, 100 percent if customer concentration is extreme.
Inventory: 50-100 percent haircut on specialized finished goods; smaller (20-40 percent) on raw materials; zero on work-in-process without clear orders.
Cash: verify restrictions, pledged accounts, FX controls; subtract restricted cash from NCAV.
Other current assets: assume zero unless you understand each line item (VAT receivables, advances, deposits).
Red flags that turn NCAV into a mirage
Rising receivables while revenue is flat or down.
Inventory growth faster than sales or gross margin compression.
Customer concentration over 25 percent of sales without credit insurance.
Auditor emphasis paragraphs on going concern or working-capital adequacy.
Repeated qualification: "slow moving and obsolete inventory" without matching write-downs.
Adjusted NCAV workflow
1) Start with reported NCAV.
2) Apply line-item haircuts above.
3) Recompute price to adjusted NCAV (P/Adj-NCAV).
4) Demand price <= two-thirds of adjusted NCAV.
5) Size based on liquidity (average daily dollar volume) and bid-ask width.
Practical examples
Tight spreads and cash-heavy: smaller haircuts, larger position.
Hardware distributor with aging inventory: heavy haircut; skip if P/Adj-NCAV > 0.8.
Single-customer manufacturer: haircut receivables sharply or avoid.
