TORONTO, March 13 (Reuters) - Rock Energy In RE.TO reported a fourth-quarter loss on Friday and said it was slashing its 2009 budget and production due to an unexpected decline in commodity prices.

Calgary-based Rock Energy also downgraded its production outlook for 2009 by 21 percent to between 3,200 and 3,400 barrels of oil equivalent (boe) per day, down from its previous estimate of between 4,100 and 4,300 boe.
Last year, Rock Energy spent C$50.2 million and produced 3,436 barrels of oil equivalent per day.
In the fourth quarter, the company reported a loss of C$2 million, or 8 Canadian cents a share, compared with a profit of C$290,000 or 1 Canadian cent a share the previous year.
