Computer Sciences Corp. adopted a stockholder rights plan that would make an unwanted takeover of the company more difficult and expensive. The El Segundo-based company said it is not aware of any potential efforts to buy or gain control of the firm, a major supplier of computer and communication systems. If a takeover began, current stockholders would be able to buy additional CSC shares at only 10% of the then-current market value, making it much more expensive to buy the necessary shares to take over the company. Stockholders, under certain conditions, could also buy the shares of an acquiring firm at a 50% discount.
