Thanks, Janet. Good morning and thanks for joining us on today's call. Today, we'll cover 3 broad areas. First, we'll take a look back on the full year 2012. Second, we'll look at, of course, fourth quarter 2012 results. And then finally, we'll conclude by looking at 2013's outlook and guidance.
Given the impending security spin, we'll be delaying the analyst meeting that we traditionally have hosted in March until later in the year, closer to the effective date of the spin. The analyst meeting is usually where we would step back a little from quarterly results and look at our progress over time and plans for the future. And since that won't occur for several months, I'll spend a few extra minutes this morning recapping our full year 2012 and our progress on the transformation that we began in the company a few years ago. Steve will then take you through fourth quarter results, and I'll end with our outlook for 2013. So again, we'll spend just a few more minutes this morning than we normally do. I don't want anybody to get nervous. We'll obviously have a lot of time for questions toward the end.
Let me start with full year 2012. In a macro environment of low revenue growth, our revenues for the year were up 1%. We increased adjusted earnings per share 23% and grew operating margins 30 basis points. In the face of some very challenging mix, our pricing excellence program delivered price realization, significantly over direct material inflation. Our Lean focus continued to show significant results in the implemented value streams, and we continue to invest in the future of the business, funding significant new product development and building our services footprint further.
Revenues from products launched in the last 3 years were about 1/4 of our total revenue. We also invested in common systems, and we will have the first go lives this year. As you'll recall, the program will continue through 2016.
Our capital allocation strategy has been consistent and shareholder-focused. We continued to increase our dividend with the announcement of additional $0.31 -- I'm sorry, 31% of an increase in December. The 2013 dividend will exceed now the 2008 peak by 17%.
In 2011 and '12, we repurchased 55 million shares for $2 billion. In 2012, we repurchased $840 million in shares. And in December, announced a new $2 billion repurchase authorization that will be used by the first quarter of 2014. Finally, we concluded a significant strategic review with our board and in December, announced the planned spin-off of our security business, which will occur late this year.
Please go to Slide 4. As I've talked about before, we started on a journey in 2010 to increase the operating capability of the company. We focused these efforts in 2 broad areas: innovation and operational excellence. In the area of innovation, we've almost doubled the proportion of our revenues from new products, which we measure as the percentage of total revenues delivered by new products introduced in the last 3 years. The new offerings have been in every sector of the business, from air compressors to unitary HVAC, to electronics locks to new service offerings.
Through new processes, talents and investments, we have increased our capability and results in areas like intellectual property development and protection, speed to market, margin improvement and market share growth. In 2012, intellectual property disclosures were up 270%, and patent filings were up 75% over the prior year. We are, by no means, done. We'll continue to invest in innovation and are focusing on multiple key growth platforms identified during our planning process.
To highlight a couple of examples of recent market introductions, on the lower left of the chart you'll see the Trane IntelliPak I. IntelliPak I systems are part of the Trane line of unitary rooftop systems designed to be the most efficient and cost-effective air conditioning units on the market. Available from 20 tons to 130 tons of cooling, IntelliPak systems deliver the highest energy efficiency rating in the industry for a standard product and are up to 20% more efficient than traditional forward-curved fans. Utilizing variable-speed compressor technology, IntelliPak I systems provide a simple turnkey solution for system setup and configuration, with lower life cycle costs. And through efficient operation and reduced maintenance demand, the new systems provide superior reliability. They're ideal for large office buildings, restaurants, retail centers, industrial facilities, institutional buildings used for health care and education. In addition to reduced energy consumption and lower life cycle cost, it provides very quiet operation in critical environments.
Lower right corner, you see the ThermoKing Precedent. The Precedent features a completely new platform for the trailer market. It's designed to be fully compliant with the new EPA Tier 4 final regulations. The Precedent platform features a new Diesel Direct Electric architecture to deliver optimum efficiencies. Testing demonstrates that the electronic throttling valves saves 30% in fuel, reaches cooling set point up to 50% faster, translating to significant operational and environmental savings for fleets throughout the life of the unit.
Please go to Slide 5. Another area of intense focus for us and for me personally has been improving our level of operational execution, which we call operational excellence. We categorize it into 4 main elements: strategic sourcing, implementing Lean through our value streams and in our functional processes and finally, with pricing.
We centralized sourcing during 2012 and organized around common commodities in order to increase our strategic sourcing capability through targeted training, standard work and the addition of external talent when needed. We also strengthened capability in emerging markets to better support supplier qualifications, supplier development and strategic sourcing in those regions. In one example, our maintenance and repair operations, or MRO commodity team, implemented the new standard sourcing process for North America, which represents an annual spend, in this case, of about $70 million. They achieved 7% productivity and also developed a road map to maintain productivity at 5% for the next 2 years. They improved days payable by 5 days. They reduced North American suppliers from over 3,000 to a select few and increased their internal customer satisfaction score to 4 on a 5-point scale.
We have 24 value streams under transformation, which happens to also represent 24% of our cost base. The value streams continue to deliver superior results and show separation in performance versus the remainder of the company. In 2012, the value streams reduced past due days by 66%; reduced cycle time by over 40%; increased cost leverage, which are the plants version of operating leverage and is based on cost throughput, by over 6 points; and had a 5-point increase in employee engagement scores while they were doing all of this. We will continue to roll out more value streams, with a plan to add 8 additional streams in 2013, which would then bring the cost base coverage to 40%.
On functional costs, we have a target to reduce our costs by 2 points of revenue over the next 3 years. Implementation of common systems is a key enabler to that reduction. We'll have our first go lives in the first half of 2013 and the implementation to continue in 6 phases through 2016.
As you can see on the bottom of the chart, these initiatives, along with innovation, has increased our margins almost 400 basis points over the last 3 years on very little revenue growth while still making significant incremental investments in the business. Operating leverage has been 38%, 31% and 73%, respectively, for the last 3 years. We started on pricing in early 2010 and have reaped benefit from better price realization and price management for the past 2 years. We looked back several years in history and couldn't find a year when we had done this, so it was a testament to the results we can produce when we focus on building a long-term, sustainable capability. This isn't just managing price lists. They're actually a fairly small component of what we've built. It's centered on capabilities like pricing elasticity analysis, value pricing of offerings and discount management.
So I'll discuss more when I come back to give the guidance. We see a continuation of challenging markets in 2013. We plan to proactively address that backdrop, as well as prepare ourselves for our new cost structure post-spin by taking restructuring actions during 2013, beginning in the first quarter. I'm proud of the progress we've made, and I'm certainly encouraged by the opportunities that lie ahead.
And with that, Steve will now take you through the fourth quarter results.
