In a report to its investors, Warner Music Group says it expects its fiscal fourth quarter revenue to increase between $2 and 22 million. WMG's fiscal Q4 ended on September 30, 2012. Warner hopes to report its Q4 revenue somewhere between $721 and 741 million, up from $719 million a year ago.

WMG also expects its recorded music division's Q4 revenue to increase from a year ago to between $598 and 614 million. Publishing revenue is expected to decrease from Q4 of last year to between $130 and 134 million. However, when it releases its official fiscal report, Warner expects to post a net loss.

The company pointed out in the investor note that changes before its official fourth quarter revenue report are possible, due to "risks and uncertainties" such as economic conditions, piracy and "our dependence on a limited number of online music stores, in particular Apple's iTunes Music Store."

In related news, WMG announced today that it has commenced separate tender offers to purchase for cash a number of its outstanding debt securities.
