Price Book Value: How to Work It Out From the Filings

“Total stockholders’ equity” is the line to find first. It sits at the bottom of the balance sheet in every 10-K and 10-Q, and it is the starting point for price to book value. Take the equity that belongs to the company’s own shareholders, subtract any preferred stock, and divide by the shares outstanding listed on the cover page of the same filing. That gives book value per share. Divide the current share price by it and you have the price to book ratio. Screeners do the same sum, but not always with the same lines or the same date.

What the ratio compares

Price to book compares what the market pays for a share with the accounting value of the equity behind it. The price-to-book metric page covers what book value measures and where the ratio fits, mainly banks, insurers and other balance-sheet businesses. Working it out yourself is about the inputs. Each one hides a choice.

Find the equity line

On EDGAR, pull up the most recent annual or quarterly report and turn to the consolidated balance sheet. Finding 10-Q and 8-K filings shows where they are. Near the bottom you will usually see some version of three lines: equity attributable to the company’s shareholders, noncontrolling interests, and total equity.

Noncontrolling interests are the parts of subsidiaries owned by outside investors. They are not yours as a shareholder of the parent. Use the line attributable to the company’s shareholders, the one above noncontrolling interests, whenever the balance sheet separates them.

If the company has preferred stock, it appears within equity too. Preferred holders rank ahead of common shareholders, so subtract it to get common equity.

Find the share count

The cover page of a 10-K or 10-Q states the number of shares outstanding for each class of common stock, as of a date close to the filing date. Use that figure. It is more recent than the balance sheet date, and it is a count of actual shares, which the weighted average share count on the income statement is not, since that one is an average over the whole period and is built for earnings per share.

Companies with more than one class of common stock list each class. Add the classes that share in the equity. The notes to the financial statements describe how the classes differ.

Do the sum

Had you used total equity and skipped the preferred stock, book value per share would have come out at 23 and price to book at about 1.3. Same company, same day. The choice of inputs moved the ratio by about 13%.

Tangible book value

Goodwill and other intangible assets sit inside book value. Goodwill comes from paying more than book for acquisitions, and it cannot be sold on its own, which is why many analysts strip it out, along with other intangibles, to get tangible book value, a stricter measure that matters most for banks and for any company carrying large acquisitions on its balance sheet.

A stock that looks modestly priced on book can look expensive on tangible book. When the two ratios sit far apart, much of the equity is acquisition premium, and a price to book below 1 means less than it seems if most of that book is goodwill.

The date problem screeners hide

The balance sheet describes the company on the last day of the quarter. The share price is today’s. Weeks or months can separate them, and in that time the company may have bought back stock, issued shares, paid a dividend or reported another quarter of profit or loss, each of which changes book value per share before the next filing shows it.

Check three things before trusting the ratio:

• The balance sheet date.
• Whether a newer 10-Q exists.
• Any buyback or share issuance announced since.

Buybacks above book value reduce book value per share. Issuance below it does the same. A big change since the last quarter end can make a screener’s ratio stale.

Nothing about the business changed, yet the ratio rose, because the company paid more than book value for the shares it retired, and a screener still working from the quarter-end balance sheet will go on showing 1.5 until the next filing arrives and the share count catches up with what actually happened.

The price side needs no special data. A delayed quote is fine for a ratio built on a quarter-old balance sheet, as the market data guide explains when it covers who needs live prices.

Track book value per share over time

One ratio is a snapshot. Book value per share from several filings in a row is a trend, and for banks and insurers it is one of the more telling series you can build, because it shows whether the equity behind each share is actually growing once buybacks, issuance and losses have all been counted.

Put the figures from the last eight quarterly filings in a column. Add back dividends paid per share if you want the full picture of what shareholders gained. A steady rise suggests the business is compounding its equity. A flat or falling line deserves a look at the notes. Losses, write-downs or buybacks above book can each explain it.

Check it against a screener

Put your figure next to a screener’s. If they match, good. If not, check in order: the equity line, preferred stock, the share count and the date. One of the four almost always explains the gap. Then decide which version you want to use, and use it the same way for every company you compare.

For funds, fact sheets often show a weighted price to book for the whole portfolio. Two bank funds with similar figures may simply hold the same banks, which checking ETF overlap will show.

Reading a 10-K covers the rest of the annual report, including the notes where equity changes are explained.

What goes wrong

• Using total equity when noncontrolling interests are large.
• Forgetting to subtract preferred stock.
• Dividing by the weighted average share count.
• Using an old balance sheet after a big buyback.
• Comparing companies on book while ignoring goodwill.
