Thank you, Rich, and thank you to our listeners for joining us today on our call. Quarter-over-quarter and year-over-year, we experienced stronger operating results in 2011 when compared to 2010. Our quarterly and annual results were driven by a combination of rate increases of 8% and 6%, respectively, and increases in customer demand of 4% and 2%, respectively, at our water utilities. In addition, in December, we received authorization from the California Public Utilities Commission to recover the accumulated balance in our Mandatory Conservation Revenue Adjustment Memorandum account or MCRAM, recognizing the balance totaling $5.7 million in the fourth quarter 2011 revenue. As we have discussed on previous calls, the MCRAM account was established to track the revenue impact of mandatory conservation instituted by the Santa Clara Valley Water District in effect from August 2009 through May 2010.
For the year, total revenue was $238.9 million compared to $215.6 million recognized in 2010. The increase was primarily attributable to $12.4 million in rate increases, $3.4 million in increased customer demand and recognition of the MCRAM. Note that despite the increase in customer demand, usage for the year was below amounts forecasted in our current general rate case by approximately 10%.
Water production costs were $92.1 million compared to $87.3 million in 2010. The increase was primarily attributable to higher unit cost for purchased water and groundwater extraction charges from the water district. In June, the water district implemented a 9% increase in the wholesale cost of water.
Operating expenses, excluding water production costs, were $92.5 million for the year compared to $90.3 million in 2010. The $2.2 million increase consisted of $2.9 million in higher depreciation, $1 million in higher property and non-income taxes related to new utility plant assets placed in service, $1 million in higher maintenance expenses related to increased water main leak repair activity, and $952,000 in higher administration and general expenses.
Recall that in the fourth quarter of 2010, we recorded a $3.6 million impairment charge on a real estate investment in Tennessee. No similar charge was required in 2011.
Interest paid on long-term debt for the year was $18.9 million compared to $15.9 million in 2010. The increase was primarily attributable to interest on the $50 million in senior notes we issued at the end of the second quarter of 2011 and the full year of interest on the revenue bonds we issued in June 2010. Also recall that in 2010, we sold 907,000 shares of California Water Service Group stock recognizing a pretax gain of $19 million. No similar sales of stock occurred in 2011.
Our net income for the year was $20.9 million or $1.11 diluted earnings per share compared to $24.4 million or $1.30 diluted earnings per share for the year ended December 31, 2010.
The trends and contributing factors impacting our fourth quarter results were consistent with our annual results. Fourth quarter revenue was $62.3 million, $11.5 million higher than the $50.8 million in revenue recognized in the fourth quarter of 2010. Fourth quarter 2011 revenue was impacted favorably by increased demand, higher rates and a recognition of the MCRAM balance.
Water production costs for the quarter were $22.3 million compared to $20.9 million in the fourth quarter of 2010. The $1.4 million increase was primarily the result of the June 2011 water district rate increases for purchased water and groundwater extraction.
Operating expenses, excluding water production costs, were $23.4 million for the quarter compared to $26.4 million in the fourth quarter of 2010. The difference is primarily due to an increase in depreciation on new utility plant placed in service and the 2010 fourth quarter real estate impairment charge.
Fourth quarter 2010 results also included $14.5 million of pretax gain on the sale of California Water Service Group stock. Again, no similar sales of such stock occurred in 2011.
Net income for the fourth quarter of 2011 was $6.6 million compared to $8.1 million in 2010, and diluted income per share was $0.35 compared to $0.43 in 2010.
During the fourth quarter of 2011, we continued our focus on utility plant investment, placing $31.3 million of net additions into service. For the year, net utility plant additions placed into service were $65.3 million, bringing our gross utility plant to $1.1 billion. As discussed previously, our long-term plans call for continued investment in our core utility plant infrastructure adding up to $300 million through 2014, subject to CPUC approval.
In 2012, we also plan on expending $12 million to $14 million on permitted utility plant additions in connection with the CPUC's resolution L-411-A. As you recall, L-411-A was issued by the CPUC to address the bonus depreciation impact that resulted from the 2010 Tax Act. Further, we plan on spending approximately $74 million over the next 3 to 4 years on our Montevina treatment plant retrofit project with construction anticipated to begin in the second half of 2012. However, we are still awaiting approval from the CPUC to move forward on this project.
Our planned utility plant expenditures in connection with the 2010 Tax Act and our Montevina retrofit project are in addition to the $300 million we plan to spend through 2014 on core utility plant infrastructure.
With that, I'd like to turn the call back over to Rich. Rich?
