Friday's Winners & Losers: Global Payments

Shares of Dollar Tree(DLTR Quote) rose 2.4% after the discount retailer announced an accelerated $150 million stock buyback program. The company will repurchase the shares from Goldman Sachs. The shares will be bought under the company's $500 million share repurchase plan, which was announced in November.

"Our share repurchase program is an important part of our capital allocation strategy," the company said. "Having successfully completed a similar transaction in recent months, we believe that the accelerated share repurchase is an efficient use of capital and will provide long-term benefit to our shareholders." Shares closed up 90 cents to $38.24.

Ares Capital(ARCC Quote) rose 1.1% after the investment company priced 13.5 million shares at $17.97 a piece, raising gross proceeds of $242.6 million. The company expects to use proceeds from the offering to repay debt, fund investments in portfolio companies, and for general corporate purposes. Merrill Lynch and Citigroup led the underwriting syndicate. Shares closed up 20 cents to $18.17 on heavy volume.

Shares of Herbalife(HLF Quote) slid 2.7% after the weight-management and personal care products company said that a takeover bid of $38 a share does not represent sufficient value. The $38-a-share bid, which was made by Whitney V LP in early February, is "too low," the company said in a press release late Thursday.

"The board recognizes and values the leadership that Whitney has provided Herbalife," Herbalife said. "We remain open-minded about ways to achieve appropriate value for the company, and would certainly consider an improved proposal from Whitney." Whitney, as of February, already owned about 27% of Herbalife's outstanding shares. Shares closed down $1.08 to $39.19.
