On an adjusted non-GAAP basis, diluted earnings per share for the quarter were $1.05 per share, that's a decrease of $0.02 or 1.9% from the fourth quarter of 2010. Consolidated operating revenues for the quarter were $457.3 million, that's an increase of $32.4 million or 7.6% from 2010. That, of course, reflects the inclusion of ALPS, the Lateral Group and Newkirk. Overall, consolidated operating income decreased by $4.2 million or 5.7% from the fourth quarter of 2010.
DST's employee healthcare and retirement benefit costs were $7.6 million lower in the fourth quarter of '11, as compared to the fourth quarter of 2010. $4.2 million of that decrease was included in the Financial Services segment, and $3.4 million was included in the Output Solutions segment. This decrease in healthcare cost resulted from the absence of some large healthcare claims last year and favorable healthcare claim experience for 2011. When we look at the past history and the current plan designs, we now think this is a trend of favorable experience that you can extrapolate into 2012, but that is the comparative data for '10 and '11.
Financial Services operating income declined from lower mutual fund shareowner processing. We had higher cost associated with business investments, those solutions in the brokerage, insurance and retirement verticals. However, these were partly offset by a lower employee healthcare and retirement benefit costs of the $4.2 million in this segment that I mentioned a moment ago.
In addition, ALPS was accretive to our fourth quarter results by approximately $0.02 per diluted share. Output Solutions operating income increased from strong performance at Output Solutions North America. And that, however, was somewhat offset by losses at IOS. The Financial Services operating revenues, overall, increased by $3.4 million or 1.2% over the fourth quarter of 2010. $14.6 million of the increase was the inclusion from October 31 of ALPS. While DST Global Solutions had increased revenues, we had lower mutual funds shareowner account fees and lower revenue at DST healthcare. Software licenses were $2.4 million, and that's 17% less than the fourth quarter of 2010.
