Answer :
Answer and explanation:
The influence a company may have over another when one of them has a number of shares that belongs to the other is determined by the percentage of ownership that the number of shares represent. If its lower than 20%, it is said the company has no influence over the other. From 20% to 50% one company has significant influence over the other. Finally, with more than 50% of the outstanding shares in possession, one company has control over the other.
In that case, CBS Corp. has no influence over Westwood One, Inc. since it owns only 18% of the outstanding shares.
