Prospect Capital Corp. (PSEC) stock rose 1.95 percent to $8.89 in the pre-market trading. The company said it has adopted a plan for the purpose of repurchasing up to $100 million of its common stock. Prospect's board has authorized the repurchase plan as it believes the recent market turmoil may cause its common stock to be undervalued from time to time. Under this plan, Prospect may in its discretion repurchase up to $100 million of its common stock at prices below its net asset value as reported in its then most recently published financial statements.

Prospect anticipates that share purchases may be made from time to time, depending upon market conditions. Shares may be purchased in the open market, including through block purchases. Prospect will not repurchase any shares from directors, officers, or other affiliates of Prospect. The repurchase program does not obligate Prospect to acquire any shares and may be discontinued at any time. Prospect intends to fund potential repurchases, if any, with available cash. The repurchase program is expected to be in effect after shareholders receive notice through the mail, which should occur in the next few weeks, until the approved dollar amount has been used to repurchase shares or the plan is terminated.
