Financial Services grew 2 percent to $44.7 million in the fourth quarter compared to $43.9 million in the prior year as the Company completed the implementation of a new core solutions customer as well as the continued ramp up of several customers implemented in previous periods. These sales served to offset the loss of legacy and core solutions from a customer that is expected to impact revenues in this segment by an additional $15-18 million in the coming year. The Commercial Markets business unit experienced an 11 percent decline to $39.7 million for the quarter from $44.7 million in the prior year due to erosion in both legacy and core solutions.
The Industrial business unit generated $17.7 million in revenue for the quarter, roughly in line with its results for the fourth quarter of 2010. Overall softness in manufacturing parts solutions related to slowed growth among HVAC/R, electrical distribution and home appliance manufacturers and a reduction in transactional documents during the quarter were the key drivers of performance.
Gross margin as a percent of revenue decreased to 29.6 percent for the current year quarter from 32.0 percent in the prior year quarter. Fixed cost absorption challenges due to unit declines, material cost increases, particularly in pressure sensitive labels, and pricing pressures all contributed to the change. Selling, general and administrative expenses, excluding pension loss amortization, declined $0.8 million to $45.2 million, or 28.0 percent of revenue, relative to $46.0 million and 26.6 percent for the prior year quarter.
Full Year Results
Total revenues declined 3 percent for the full year versus 2010. As with the quarter, declines in legacy products outpaced the growth that was experienced from core solutions. However, as the year advanced the mix changed from 63 percent legacy and 37 percent core for 2010 to 60 percent legacy and 40 percent core for 2011 signaling a subtle shift in the portfolio composition.
Healthcare revenues declined 6 percent to $236.8 million from $251.0 million in the prior year mainly due to administrative and clinical documents that are largely being phased out as part of the EMR initiatives. The acquisition of Dialog Medical improved our software and services offering and contributed $2.2 million in revenue during the second half of 2011. In spite of the customer loss incurred during the fourth quarter, core solutions grew organically during the year.
Revenues in the Financial Services unit declined less than 1 percent for the year to $174.2 million from $175.7 million in 2010 reflecting a still heavy concentration in declining legacy transactional products. Implementation of new customers and expansion in marketing and critical communication solutions largely offset these declines. Commercial Markets revenues were $159.4 million for the year, a 7 percent decline from $170.6 million in 2010. The upgrade of our digital print network was very evident in this segment as we posted solid growth for the year. However, softness in core solutions sales as well as decreases in areas such as transaction labels created an overall decline for the segment.
Industrial revenues grew 9 percent to $77.8 million from $71.1 million in 2010 reflecting a strong first half within our customer base followed by a weaker second half. In-mold labeling solutions continued to make progress in increasing the pipeline of opportunities as well as booked revenues. Our Mexico operation also made progress with 24 percent revenue growth over the prior year and reporting profit for the current year.
Gross margin as a percent of revenue declined to 30.6 percent in the current year from 31.4 percent during the prior year. Selling, general and administrative expenses, excluding pension loss amortization, declined $3.6 million for the full year to $182.4 million, or 28.1 percent of revenue as compared to $185.9 million and 27.8 percent of revenue in the prior year.
