Good morning, and thank you, Jeff. And good morning to those of you who are listening to our 2011 year-end earnings conference call. As Jeff mentioned, our 2011 10-K will be filed within the next day, as we continue to work with our auditors to make sure all the Is are dotted and Ts are crossed. Jeff has just reviewed with you some of the highlights for 2011. I will also briefly add some additional detail around the results for the year.
Turning to the Slide 8. Our overall 2011 was another year of strong financial performance with increases in revenue, net income and cash flow, as well as continued improvement in our regulated O&M efficiency ratio. For 2011, we reported operating revenues of approximately $2.7 billion, a $111 million or 4.4% increase over the $2.6 billion reported for 2011. GAAP earnings per share increased approximately 14%. Included in the GAAP number and related only to our discontinued operation is a per share benefit of $0.09 related to the cessation of depreciation, as well as a noncash charge of $0.14 related to the write-down of parent company goodwill associated with these discontinued operations.
This write-down should have been recorded in the first and second quarter of this year. Therefore, when reviewing our 2011 financial statement, you will note in footnote 22, we have recast the 2011 quarterly results. This recast had no impact on ongoing net income, EPS or cash flow, and our year-end financial statements are correct.
As some of you may remember, when American Water was purchased by RWE in 2003, the premium RWE paid for American Water was booked at the parent company level. Even though American Water was sold in 2008 through a public offering, that goodwill remains on our books. When we sell subsidiaries, the goodwill associated with those subsidiaries also needs to exit our book. Since I'm sure that someone will ask this question, let me say that the annual goodwill impairment test, which we performed at the end of 2011, showed that there was no impairment to the $1.2 billion of goodwill that is on our books.
For the full year 2011, net income and diluted earnings per share, adjusted for the cessation of depreciation and the write-down, was approximately $319 million compared with the approximately $268 million for 2010; or $1.81 per diluted share, compared with the $1.53 per diluted share in 2010. The adjusted net income and adjusted earnings per share represent American Water's ongoing operation, which is, as we have mentioned on previous calls, we feel is more appropriate way to view our business results.
Now I'd like to turn the discussion to the various components of our net income, starting, of course, with revenue. Overall operating revenues increased $111 million year-over-year. Operating revenues from our Regulated business increased approximately $83 million or 3.6%, driven by $134 million in rate increases obtained through rate authorizations for a number of our operating companies, which is related to our continued prudent investment in infrastructure to ensure reliable service. Revenue increases related to rates granted were offset by decreased revenues of approximately $57 million, attributable to decreased water sales volume in all customer classes in 2011, compared to 2010. And I'll be addressing water sales shortly.
As of today, we have 8 rate cases filed and awaiting final orders totaling approximately $258 million. There is, of course, no assurance that the filed amount of the rate cases will be what is finally awarded. A list of rate cases resolved and outstanding can be found in the appendix of this presentation.
And finally, our market-based operations revenues increased by $33 million during 2011, compared with the prior year. The increase was primarily attributable to the increase in contract operations group's revenue of about $22 million. This increase is mainly the result of incremental revenues associated with military construction and O&M projects of $43 million, partially offset by lower revenues associated with other expired or terminated contracts.
Now let me spend a few minutes talking about our water sales, the trends we are experiencing and the actions we are taking. The bar chart in this slide shows total water sales volumes from 2007 to 2011 in millions of gallons, and the tables show you the breakdown of the different customer classes. Except for 2010 which, if you remember, was characterized by a hot and dry summer in the Northeast, the overall trend has been one of declining water usage across all of our customer classes throughout all of the states in which we operate regulated subsidiaries.
The rate of decline over the past 5 years in our various states has ranged between 1.3% to 3.4%. Some of the variations are attributable to weather conditions and the overall economy. But increased water conservation, including the use of more efficient household fixtures and appliances, as well as declining household prices are affecting our water sales. This decline in usage contributes to regulatory lag and is an issue that we addressed in the rate cases that we filed in 2011 and will continue to address in all future rate cases.
Now in Slide 11, you can see total operating expenses for 2011 increased by approximately $36 million or 2% from 2010. Regulated operating expenses increased $21 million or 1.3% for 2011, compared with 2010. But really, that is primarily due to higher depreciation expense of just about $21 million resulting from additional utility plants placed in service and increased general taxes of $5 million, primarily attributable to higher gross receipt tax in our New Jersey regulated subsidiary.
Now offsetting these increases is lower O&M expense, mainly due to a decreasing usage, as we noted, mainly in our New Jersey subsidiary due to record rainfall in August. Our market-based operating expenses increased by about $22 million, mainly driven by expenses associated with our contract operations group increased activity in our military construction project.
Our continued focus on operating expenses can be seen in the continued improvement in our O&M efficiency ratio. As Jeff mentioned, for the year, our regulated entities O&M efficiency ratio decreased to 43.8% compared with 45.5% in 2010 and 47.7% in 2009. Our long-term O&M efficiency ratio goal of less than 40% is an important goal for this company, as it allows us to continue to invest needed dollars in our infrastructure, including IT systems, while lessening the impact of rate increases to our customer.
Let me talk a little bit about capital expenditures both for 2011 and '12. In '11, American Water invested $925 million in company-funded capital improvement, compared to $766 million in 2010. The company's continued investment in pipes and plants to ensure reliable service included the start of 2 large capital projects: a $100 million project in Pittsburgh to upgrade 2 water treatment plants and associated pumping capacity that will benefit over 0.5 million people; and a $75 million project to replace a 1920s era water treatment facility in New Jersey.
In '11, we also moved forward with our Business Transformation project to upgrade technology systems, which will ultimately provide more cost-effective and value-based services to customers, and result in enhanced value for our shareholders. We expect the ERP application to go live in August of '12, and the new customer information system and enterprise asset management system to be implemented throughout 2013. Total expenditures spent for our Business Transformation project through the end of '11 was approximately $140 million, of which about $100 million of that had been spent in 2011. As we mentioned in our guidance call for '12, we intend to invest about $900 million to upgrade and maintain our water system.
And lastly, on Slide 14, we've provided a bridge to take you from our 2011 GAAP earnings per share of $1.75 to the ongoing adjusted earnings per share of $1.78, so you can have an apples-to-apples basis to compare against our 2012 ongoing operations guidance of $1.90 to $2 a share. Of course, these forecasts are subject to numerous risks, including those described under forward-looking statements in our earnings press release and in our 10-K. As a result of American Water's 2011 portfolio optimization effort, the company does not anticipate the need for an equity offering in 2012.
And with that, I'd like to turn the call back to Jeff for closing comments before opening it up for your questions.
