Carlyle Group LP swung to a third-quarter profit as rising markets buoyed its portfolio and offered a continued opening to sell out of investments of years past. The Washington, D.C. private-equity firm reported a profit of $800,000 for the period ended Sept. 30. On a per-share basis, Carlyle lost 2 cents, because of the accounting treatment of certain ownership units held by Carlyle's founders, which didn't receive a tax benefit.
