One of the biggest considerations companies make when deciding whether to acquire another company is how fairly priced the company is. If the company is overvalued, others will not be interested in buying it.

Analysts and investors follow potential takeover/leveraged buyout targets because when a company announces that it is being taken over, its stock price usually jumps to reflect the takeover premium being paid. This is usually a profitable event for shareholders.

We compiled a list of rumored potential takeover/LBO targets from various sources including CNNMoney and Wall St. Cheat Sheet. We then compared their stock prices to their Graham numbers to find those that may be attractively priced or undervalued.

The Graham number is a measure of maximum fair value created by the "godfather of value investing," Benjamin Graham. It is based on a stock's earnings per share and book value per share:

Graham number = Square Root of (22.5 x Trailing-12-Month EPS x Most-Recent-Quarter BVPS)

The equation assumes that the P/E ratio should not be higher than 15 and the P/BV ratio should not be higher than 1.5. Stocks trading well below their Graham number, or their maximum fair value, may be undervalued. This could indicate that the stocks have more value to price in.
