1. There are three main methods for valuing shares: the Earning Capitalization Method (ECM), Dividend Capitalization Method, and Fair Value Method. 2. The Intrinsic Value or Net Asset Value of shares is also calculated, which is the net worth per share based on assets, liabilities, and number of shares. 3. The Fair Value Method values shares for controlling interest by taking the intrinsic value and adding the value from the ECM. This comprehensive approach incorporates both asset-based and earnings-based valuation.
