Book Value
Definition
Book value is the net asset value of a company as recorded on its balance sheet — total assets minus total liabilities. The formula is simple: Book Value = Total Assets − Total Liabilities. For intangible-rich businesses, book value typically understates economic value by a wide margin because most internally generated intangibles (brands, customer relationships, R&D, organisational capital) are expensed rather than capitalised under IAS 38 and ASC 350. **Worked example.** A SaaS company has £15m total assets on the balance sheet (£5m cash, £8m receivables, £2m equipment) and £8m total liabilities. Book value is £7m. The same business generates £20m ARR with 90% net revenue retention, holds £40m of customer-contract intangibles built over six years of selling, and runs on a proprietary technology platform that took £12m of cumulative R&D to build. None of those intangibles appear on the balance sheet because they were generated internally. The market valuation is £160m — 23× book value. The gap is the intangible asset base that book value doesn't see. **Why the gap matters.** Lenders that anchor on book value underwrite to the wrong number, which is why IP-backed lending programmes (NatWest, HSBC, RBS) increasingly underwrite to intangibles. PE buyers running purchase price allocation under IFRS 3 / ASC 805 turn the gap into goodwill and identifiable intangibles — but only at the point of acquisition. Equity investors price the gap explicitly through valuation multiples that exceed book value by a factor that grows with the intangible-intensity of the sector (typically 1-3× for industrial businesses, 5-15× for SaaS, 20×+ for platform businesses). **Book value vs market value vs intrinsic value.** Market value is what an arm's-length buyer would pay today; intrinsic value is what the discounted cash-flow model produces from the asset's expected economic benefit. Book value is the most conservative of the three because it reflects only what the accounting framework permits onto the balance sheet. Across the S&P 500, the price-to-book ratio has averaged over 3× for two decades — a structural signal that the accounting framework systematically understates economic value in the modern economy. **Practical use.** Founders preparing for a Series A or exit should maintain a separate intangible asset register alongside their statutory accounts. Tracking quarterly investment in brand, customer acquisition, R&D, technology, and organisational capital — even when those costs are expensed — produces the evidence base that supports a valuation conversation with investors, lenders, or acquirers. Book value is a starting point, not an answer.

A measure of a company's financial performance that calculates the value created above the required return of investors, defined as net operating profit after tax minus the cost of capital employed. EVA highlights whether a firm's intangible and tangible assets are generating returns that exceed their cost of capital.

The intangible premium that a business commands above the fair value of its net tangible assets, reflecting factors such as brand strength, regulatory licences, customer loyalty, and market position. Franchise value is a critical concept in financial services and regulated industries where the right to operate carries significant economic worth.
An actuarial valuation methodology used to value life insurance companies, representing the present value of future profits from the existing book of insurance policies (the value of in-force business) plus the adjusted net asset value of the company. Embedded value is the standard valuation framework for life insurers and is analogous to the net asset value plus intangible asset value approach used in other industries.
The estimated value of a business or asset beyond the explicit forecast period in a discounted cash flow analysis, representing the bulk of total enterprise value for long-lived assets. Terminal value is calculated using either a perpetuity growth model or an exit multiple approach and is particularly significant for intangible-intensive companies with long-duration competitive advantages.

What is the difference between tangible and intangible assets?
Tangible assets are physical items like buildings, machinery, and inventory. Intangible assets are non-physical sources of value — patents, brands, software, customer relationships. Intangibles now drive most enterprise value.
