Book Value
The net asset value of a company is calculated by subtracting total liabilities from total assets. Book value per share is a common metric used to assess whether a stock is undervalued or overvalued.
01—What is Book Value?
The definition — and what it means in practice.
Book value is the accounting value of a company’s net assets: total assets minus total liabilities, as shown on the balance sheet. It represents the residual value attributable to ordinary shareholders after settling all obligations. “Book value per share” (BVPS) divides that net asset value by the number of shares outstanding, giving a per-share figure that can be compared with the market price.
Book value matters because it anchors valuation to what the company owns and owes, rather than to market sentiment. Investors often compare a share’s price with BVPS to judge whether the market is pricing the company above or below its balance-sheet value. It is most informative for asset-heavy businesses, and less reliable for firms where brand, software, or growth prospects drive value more than recorded assets.
If assets are Rs 1,000 and liabilities are Rs 600, book value is Rs 400; with 100 shares, BVPS is Rs 4 per share.
Book Value = Total Assets − Total Liabilities; BVPS = Book Value ÷ Shares Outstanding
Inputs come from the balance sheet; shares outstanding are the total issued shares (not the board lot).
- Book value is net assets: what the company owns minus what it owes.
- BVPS converts that net asset value into a per-share number for comparisons.
- Price versus BVPS is commonly summarised as the price-to-book (P/B) ratio.
- Book value is accounting-based and can differ from realisable market values of assets.
- It tends to be less useful when intangible value drives the business.
02—How book value works on the PSX
The Pakistan-specific rules, conventions, and numbers.
On the Pakistan Stock Exchange (PSX), book value is typically taken from a listed company’s audited financial statements and other periodic accounts. Because listed companies must publish audited annual accounts and hold an Annual General Meeting under the Companies Act 2017, investors usually have a consistent, documented balance-sheet basis for calculating book value and BVPS.
PSX investors most often encounter book value when screening or comparing shares across sectors. A common workflow is to look at a company’s market price and then relate it to BVPS (or directly to the price-to-book ratio) as one input in fundamental analysis. Book value is not a trading rule, and it does not indicate how quickly a share price will move in the market.
03—Common misconceptions
Where investors most often get this wrong.
If the share price is below book value, it is automatically undervalued.
Not necessarily. Low price versus book value can reflect weak profitability, poor asset quality, high risk, or uncertainty about whether assets can be realised at stated values.
Book value tells me what I would get if the company shut down.
Book value is an accounting residual, not a liquidation estimate. In a real wind-down, asset sale prices, costs, and claim priority can make outcomes higher or lower than book value.
Book value captures brand value and future growth.
Mostly it does not. Many valuable intangibles and growth options are not fully reflected in balance-sheet assets, so book value can understate economic value for some businesses.

05—Frequently asked questions
What investors ask about book value on the PSX.
Frequently Asked Questions
Use the company’s balance sheet: subtract total liabilities from total assets to get book value. For book value per share (BVPS), divide that result by the number of shares outstanding.
Book value comes from accounting statements (assets minus liabilities). Market value reflects what investors are willing to pay in the market, expressed through the share price (and market capitalisation). They can differ widely.
No. Face value is a nominal figure (often Rs 10 per share for listed companies) used for capital structure and some corporate action conventions. BVPS is derived from net assets and can be above or below face value.
It can suggest the market price is low relative to net assets, but it does not prove a bargain. Profitability, asset quality, debt levels, and business outlook all affect whether a low P/B is justified.
Book value changes when assets, liabilities, or retained earnings change in the accounts. Share price can stay flat (or move differently) because it is driven by trading and expectations, not only by reported net assets.
