Thanks, Rich, and good morning to everyone. Let me begin by saying how much I am looking forward to my new opportunities as Chief Operating Officer, which is allowing me to spend more time with our customers and work closely with our division presidents to accelerate growth and margin expansion.
Rich discussed the total company's first quarter results so I will now review the performance of each of our platforms in more detail. Our Distribution platform increased revenues by 6% in the first quarter versus prior year, setting a first quarter record of $263 million. Distribution also delivered an all-time record quarter in both operating income and return on sales led by gains in the health care and industrial end markets.
As a result of these gains, coupled with margin expansion, operating income increased 14% over prior year to $16.7 million for the quarter. At a 6.4% return on sales, this marks the first time in history this segment has surpassed 6% and it is substantially exceeding our 2012 target of 4% to 5%.
Price inflation and inventory prebuys helped us modestly. We estimate this to be approximately $2 million of operating income benefit in the first quarter 2012 versus a $1 million of benefit in the first quarter of 2011.
Turning to Performance Products and Solutions. Revenues in this platform increased 7% in the quarter versus last year, due to gains in appliance, packaging and wire and cable end markets as well as from higher pricing due to raw material inflation. PP&S increased operating income by 24% over the prior year to $17.8 million, resulting in a return on sales of 8%, 110 basis point improvement over the first quarter of last year.
Specialty Platform revenues increased by 11% over prior year to $325 million, driven by the ColorMatrix acquisition and higher selling prices as a result of raw material inflation. Operating income in the quarter increased to a record level of $29.1 million, a 15% increase over last year resulting in return on sales of 9%, a 40 basis point improvement over the last year and a record first quarter result.
Breaking the Specialty Platform down into its segments, Global Specialty Engineer Materials sales declined over prior year by 7% to $142 million in the quarter, predominantly due to lower demand in Europe. We also saw a continued softness in demand for solar and nuclear applications. This resulted in operating income of $11.8 million, a 16% decrease compared to prior year and return on sales of 8%. As you know, these unfavorable market forces are not new and have lingered from the second half of 2011. We continue to focus on winning new business and developing new applications to counter the softness in overall demand.
Global Color, Additives and Inks grew revenue by 30% to $183 million, due to the ColorMatrix acquisition, offset partially by a decline in European demand. Operating income in Global Color of $17.3 million was a new record for the segment, and was up 54% over prior year first quarter. This resulted in a record return on sales of 9.4% and improvement of 150 basis points over last year.
As Rich said, the ColorMatrix integration is going better than planned. Our priority is to focus on supporting growth initiatives through this acquisition. With that in mind, during the first quarter the ColorMatrix sales team participated in our Global Sales Conference where our sellers from around the world built relationships, trained and developed plans to execute cross-selling initiatives across our customer bases.
In addition, we hosted technology reviews focused on identifying opportunities to accelerate innovation synergies, spanning markets, geographies and product lines. We are exploring opportunities to translate the existing technology between organizations to fill gaps in each other's technology portfolio. Broadly speaking, we are actively qualifying opportunities in flame retardant, gas barrier and surface energy additives. We are discovering the value of the networking that is occurring in these early stages of integration.
From our internal relationship building, we are already uncovering opportunities and leveraging our collective footprint in emerging markets. While we have nothing specific to announce today, this may lead to future investment in high-growth markets like India, South Africa and Brazil.
Successfully integrating ColorMatrix is a critical imperative for us this year no doubt. And we are off to a great start. But equally important, we must accelerate profitable growth in Asia with operating margins about half that of the Specialty Platform, there is much more room for improvement. With our new leadership in place there and proven four-pilar strategy, we are confident we will be accelerating our growth in this region soon. Now we must overcome weakness in Europe and we are doing this. With a global addressable market of way over $30 billion, there's no shortage of opportunities. We can capture, do cross-selling and improvements in sales force effectiveness. This concludes my prepared remarks in the first quarter and I'll now turn the call back over to Steve.
