Summary Box: AOL Revenue Slides In 4Q

THE QUARTER: Internet company AOL Inc., which separated from Time Warner a little over a year ago, said fourth-quarter earnings rose from a year-ago period weighed down by restructuring charges. However, revenue declined on weaker ad sales and a drop in dial-up Internet subscribers.

TURNAROUND: AOL is in the midst of a turnaround as it works to shed unprofitable businesses and acquire new ones that attract more customers and the advertisers who follow them.

SHARES DOWN: Though the company's results surpassed Wall Street expectations, investors sent shares down about 4 percent by midday.
