How to Calculate P/B in CAD from Filings

P/B looks simpler than P/E because there is no trailing twelve-month build: book value is a single balance-sheet number. The work is in taking the right equity figure, the right share count and, for companies that report in US dollars, the right exchange rate. This post is a worksheet for non-bank issuers.

For the concept, see what P/B means for Canadian DIY investors. The share-count and currency habits are the same as in how to calculate P/E in CAD from filings, so this post focuses on what is different for book value. It is educational; numbers are hypothetical.

Direct answer

1. From the latest balance sheet, take equity attributable to shareholders of the company (not total equity, which includes non-controlling interests).
2. Subtract preferred shares and other equity instruments that rank ahead of common shares.
3. Divide by common shares outstanding from the most recent date you can find (the MD&A’s outstanding share data section).
4. If the company reports in USD, convert book value per share at the closing rate on the balance-sheet date.
5. P/B = CAD share price ÷ CAD book value per share.

Worked example (hypothetical, CAD reporter)

Step	Input	Source	Value
1	Total equity	Balance sheet	C$5,200M
2	Less non-controlling interests	Balance sheet (equity section)	−C$300M
3	Less preferred shares	Balance sheet or share capital note	−C$400M
4	Common equity	5,200 − 300 − 400	C$4,500M
5	Common shares outstanding	MD&A outstanding share data	300M
6	Book value per share	4,500 ÷ 300	C$15.00
7	Share price	TSX quote	C$18.00
8	P/B	18.00 ÷ 15.00	1.20x

Worked example (hypothetical, USD reporter)

Step	Input	Value
1	Common equity	US$3,000M
2	Common shares outstanding	200M
3	BVPS in USD	US$15.00
4	USD/CAD closing rate on the balance-sheet date (hypothetical)	1.38
5	BVPS in CAD	15.00 × 1.38 = C$20.70
6	TSX share price	C$24.84
7	P/B	24.84 ÷ 20.70 = 1.20x

Book value is a balance-sheet figure, so it uses the closing rate on that date, not the average rate you would use for earnings. Exchange rates are published by the Bank of Canada. If the stock also trades in New York, you can instead divide the USD price by USD book value; you should get nearly the same answer.

Where each input comes from

Input	Where to find it	Watch for
Equity attributable to shareholders	Balance sheet, equity section	Some issuers label it “owners of the parent”
Non-controlling interests	Balance sheet, equity section	Large for companies with partly owned subsidiaries
Preferred shares and hybrids	Balance sheet or share capital note	Some hybrid notes sit in equity; treat them like preferreds. See preferred shares and hybrid capital
Shares outstanding	MD&A outstanding share data (Form 51-102F1) or cover of the AIF	Use the latest date; buybacks or issues change it
Multiple share classes	Share capital note	Add all classes that share equally in equity
Goodwill and intangibles	Balance sheet	Needed later for tangible book, a separate measure

Choices that change the answer

Choice	Effect	Default
Total vs attributable equity	Including NCI overstates book per share	Attributable to shareholders
Preferreds left in	Overstates common book value	Subtract them
Old share count	Misses buybacks or new issues	Latest outstanding share data
Basic vs diluted shares	Diluted lowers BVPS if options are in the money	Basic for book; check dilution with cap tables and fully diluted share counts
Average vs closing FX rate	Average rate is wrong for a balance sheet	Closing rate
Insurer book plus CSM	Raises book for IFRS 17 insurers	Show both, labelled

Checklist

Step	Done when
Equity figure	Attributable to shareholders, latest quarter end
Preferreds removed	Preferred shares and equity-classified hybrids subtracted
Share count	Latest outstanding share data, all common classes
Currency	Closing rate at the balance-sheet date if not CAD
P/B recorded	With date, equity basis and any CSM adjustment noted

With a P/B in hand, compare it fairly using P/B vs peers, and check the accounting traps in when P/B misleads on TSX stocks.
