Our earnings release and financial presentation include non-GAAP financial information that we believe enhances the overall understanding of our current and future performance. We have included reconciliations of the differences between GAAP and non-GAAP financial measures in our earnings release and financial presentation.
I'd also like to cover our Safe Harbor statement. We will be making statements during this call that are forward-looking. These statements are based on our current expectations and assumptions that are subject to risks and uncertainties. Actual results could differ materially from these expectations because of factors discussed in today's earnings release and the comments made during this conference call and in the Risk Factors section of our Form 10-K, Form 10-Q and other reports and filings with the Securities and Exchange Commission. We do not undertake any duty to update forward-looking statements.
You will notice in our press release and investor presentation our new segment reporting. Our reporting segments have changed from North America and International to Global Energy and Water segments. This reflects how we are running the business after completing our corporate reorganization. We also believe the new reporting will provide investors with more insight into our business as we are now providing revenue, gross profit and operating income measurements for our Energy and Water businesses.
To provide some context for this change, you can reference the profile of our Energy and Water segments for 2011 on Slide 4 on the investor presentation. This slide depicts our full year 2011 results in the new segment view, including revenue for Electricity, Gas and Water and gross and operating margins for Energy and Water segments.We have also provided on our investor website a preliminary unaudited schedule recast -- that recap 2011 by quarter into the new segment disclosure that we hope will further assist you.
