Favorable redundancies on prior year's loss reserves decreased to $64 million or 12 points of favorable development, compared to $75 million or 16 points of favorable development in 2011. The decrease is primarily due to less favorable development of prior year's losses in the Excess and Surplus line segment.
In the first quarter of 2011, we resulted significant portion of our outstanding liabilities associated with an Errors & Omissions program from mortgage servicing companies and as a result reduced loss reserves by $16 million.
Next I will discuss the results of our non-insurance operations, which we call Markel Ventures. In 2012, revenues from our non-insurance operations were $97 million, compared to $68 million in 2011. Net income to shareholders from our non-insurance operations was $200,000 in 2012, compared to $2.4 million in 2011. Revenues from our non-insurance operations increased in 2012, compared to 2011, primarily due to our acquisitions of Baking Technology Systems Incorporated and WI Holdings Incorporated in late 2011. The decrease in net income to shareholders from our non-insurance operations is a result of decreased shipments for the quarter in our manufacturing operations where we expect to see improvements as the year progresses.
