Canton, Mass., Consumer electronics retailer Tweeter Home Entertainment Group named Joe McGuire as president and CEO. McGuire has been serving as interim CEO since March 15. He said today that the company would soon release its third quarter earnings report. “We need an extra day or two to complete the review of our accruals and reserves around our restructuring charges and discontinued operations allocation from our store closing plan,” he said. “Many of these constitute significant estimates on the company's part, and we want to be sure that we are comfortable with them."
