Applying "Treasury Stock" to Securities Exams:
Companies may wish to repurchase their own shares to fund an employee stock purchase plan or to regain control of the company. A company may want to reduce the number of shares outstanding to protect itself from a hostel take over. Shares that have been repurchased by the company reduce the number of shares outstanding but do not reduce the number of shares that have been issued.
