Thank you, Emily. Welcome, everyone, and thank you for joining us today. On the call with me is our President and CEO, Bob Sprowls. I would like to first remind you that certain matters discussed during this conference call may be forward-looking statements intended to qualify for the Safe Harbor for liability established by the Private Securities Litigation Reform Act of 1995. Please review a description of our company's risks and uncertainties in our most recent Form 10-K and Form 10-Q on file with the Securities and Exchange Commission. Please also refer to our earnings release in the Form 10-K issued early -- earlier today for details regards to our earnings and financial information.
I'm very pleased to note that 2011 was a year of a strong financial performance with increases in revenues, net income and cash flow. For 2011, we reported net income of $45.9 million compared to $32.2 million for 2010. Net income from continuing operations was $42 million, representing an increase of $10.9 million compared to 2010. Diluted earnings from continuing operations were $2.23 per share for 2011 as compared to $1.66 per share for 2010. I would like to remind you that earnings for 2010 were impacted by a pretax charge of $0.55 per share recorded for the impairment of assets and loss contingencies resulting from regulatory matters and $0.19 per share of pretax income for contract modifications that were retroactive received by our contracted services business of American States Utility Services or ASUS. Excluding the effects of these 2 items, 2011 diluted earnings from continuing operations increased by $0.21 or 10.4% over 2010's adjusted earnings of $2.02 per share.
For 2011, our operating revenues increased by $20.3 million or 5.1% to $419 million -- $419.3 million. Excluding the impact of the 2010 contract modifications received by ASUS previously mentioned, our total revenues increased by $25.9 million, partially driven by the CPUC-approved rate increases of $9.5 million for our regulated water and electric operations that were effective January of 2011.
In addition, revenues from our Contracted Services business of ASUS increased by $16.4 million resulting from higher construction activities at the military bases and favorable changes in cost estimates resulting in additional construction revenues recorded under the percentage of completion method of accounting. Supply costs were $102 million for 2011, which was similar to the adopted level approved by the CPUC. Any changes in purchased water, power and pump taxes were covered by the Modified Cost Balancing Account or MCBA.
Other operating expenses decreased slightly to $28.8 million in 2011 as compared to $29.2 million in 2010 due to lower water conservation and treatment costs. Administrative and general expenses for 2011 decreased by $12 million as compared to 2010. As I discussed earlier, a pretax charge was recorded in 2010 for the impairment of assets and loss contingencies resulting from regulatory matters for our water operations. This matter has since then been settled and no further charges are anticipated at this point. Excluding the impact of this charge, our A&G expenses increased by approximately $4.6 million in 2011 as compared to 2010, primarily due to increases in labor and employee benefits, as well as higher consulting and other outside services costs.
Depreciation and amortization expenses increased by $944,000 to $38.3 million in 2011 due to capital additions, partially offset by asset retirements. Maintenance expense decreased by $792,000 to $17.4 million in 2011 due to a reduction in planned and unplanned maintenance work.
Our construction expenses for contracted services at ASUS increased by $9.8 million for the year. This increase is due to additional construction projects at Fort Bliss and Fort Bragg military bases. In 2010, we recorded a pretax gain of $643,000 for the sale of property compared to only $128,000 pretax gain on sale of property in 2011. Interest expense increased by $2 million in 2011 as compared to 2010 was mainly due to the issuance of $62 million notes in April of 2011, $22 million of which was used to redeem notes with a higher interest rate.
Interested income decreased from $2.4 million in 2010 to $859,000 in 2011 mainly due to interest income of $1.3 million recorded in 2010, resulting from a proposed settlement with the IRS related to AWR's tax refund claim. There were no similar interest income in 2011.
For the year ended December 31, 2011, income tax expense increased to $30.1 million as compared to $23 million for the same period in 2010 due primarily to an increase in pretax income. As discussed in our previous earnings calls, we completed the sale of Chaparral City Water Company in May of 2011. Net income from discontinued operations for 2011 was $3.8 million or $0.20 per share, which included the net gain of on sale of $2.2 million or $0.12 per share, as well as 5 months of operating activities in 2011.
I will move on to briefly discuss the fourth quarter results. For the fourth quarter, our net income from continuing operations was $6.7 million or $0.35 per diluted share as compared to $8.3 million or $0.44 per diluted share for the same period in 2010. Please keep in mind that included in the fourth quarter of 2010 was the impact of the full year rate increase from the CPUC decision for the Region II and Region III and general office rate case, which was retroactive to January 1, 2010.
Excluding the impact of the rate increases for the periods January through September 2010 and the previously mentioned impairment charges recorded in the fourth quarter of 2010, our fourth quarter earnings increased by $0.04 per share or 12.9% increase year-over-year. The $0.04 increase is primarily due to continuous growth in our contracted services business as we work closely with the government to resolve pending contract modifications and to obtain additional contract construction opportunities. A more detailed discussion of our fourth quarter results is included in our earnings release issued this morning.
I want to now take a few minutes to talk about the Water Revenue Adjustment Mechanism, also known as the WRAM mechanism, and perhaps, clarify a few things. First of all, the increasing block rates were implemented as a means to help achieve the conservation goals mandated by California law and incorporate it into the CPUC's Water Action Plan. In order to comply with this policy objective, Golden State Water, along with certain other California utilities, changed the rate structure from a single volumetric rate to an increasing block rate design. At the same time, we reduced our fixed monthly service fees charged to customers. This kind of changes in rate design have increased revenue volatilities and placed a larger portion of our fixed cost at risk of not being recovered due to sales fluctuations. The CPUC approved WRAM mechanism mitigates this kind of risk by decoupling revenue from water usage, so that utilities are not adversely affected by sales reduction as a result of water conservation efforts by customers. The mechanism is designed to keep the utilities whole, thus providing shareholder with consistent returns.
Next, I want to address an accounting rule that required us to collect the WRAM balances within 24 months, following the year in which they are recorded. Any WRAM balances estimated to be still outstanding 24 months after the year end must be deferred and instead will be recorded as revenue when collected. We have been assessing our WRAM balances since 2009 under the CPUC guidelines. Most of our WRAM balances or WRAM surcharges are in effect for 24 months, which under the accounting rule would allow us to record a full amount of WRAM revenue.
As of December 31, 2011, the estimated WRAM balances not collectible within 24 months were immaterial. And as a result, no water revenue has been deferred thus far. We, along with 3 other water utility companies, California utility companies, filed an application in 2010 to the CPUC to modify the recovery period of the WRAM to 18 months or less.
Until the CPUC issues a favorable decision on the 18-month recovery period, we will continue to assess our WRAM balances. We believe that increasing tiered rates to encourage conservation, coupled with WRAM and MCBA to keep the utility whole is still one of the lead cost alternatives to managing the water supply issues in California.
It is also important to note that revenue in the WRAM balances are not necessarily due to a reduction in sales, per se, but due to a difference between actual and forecasted sales volume. So when we filed the general rate case in July of 2011 for rates effective 2013, more current customer consumption data was used to calculate rates.
As a result, beginning with 2013, I don't anticipate as significant of a variance between actual and forecasted sales levels as we have experienced so far. Therefore, the recovery period for 2013 WRAM balances and beyond should not be longer than 24 months.
We continue to file for recovery of our WRAM balances in a timely manner. In 2011, we billed $15 million to customers for collection of the 2009 and 2010 WRAM balances. This surcharge has decreased the WRAM balances, increased the company's cash flow and do not impact earnings. We also implemented a surcharge in early March of 2012 to collect the 2011 WRAM balances.
In terms of cash flow, net cash provided by operating activities was $80.2 million for the year ended December 31, 2011, as compared to $53.8 million for the same period ended December 31, 2010. The $26.4 million increase was primarily due to rate increases approved by the CPUC for all of our regulated businesses and the collection of surcharges to recover previously recorded regulatory assets, including $15 million for prior year's WRAM balances.
As discussed earlier, we received a late decision on the Region II, Region III and general offices rate case in the fourth quarter of 2010. At the time, Golden State Water reported a $19.5 million increase in regulatory assets, representing the difference between interim and final rates authorized by the CPUC. In 2011, we collected approximately $8 million of these differences. Golden State Water also invested $78 million in capital projects in 2011 as compared to $77 million for 2010. The capital expenditures were consistent with our 2011 capital improvement plan. We expect to incur approximately $70 million to $80 million of capital expenditures in 2012 primarily for upgrades to Golden State Water's water supply and distribution facilities.
Impacting cash flow from financing activity was the issuance of $62 million notes in April of 2011 by Golden State Water. A portion of the proceeds from issuance were used to redeem $22 million of notes with higher interest rates. As a result of the increased cash generated from operating activities and its long-term debt issuance, Golden State Water was able to fund its $78 million capital investments and reduced the need for borrowing from American States. At December 31, 2011, Golden State have, had no intercompany borrowings.
At the consolidated level, the cash proceeds from the sale of Chaparral reduced the need for short-term borrowings under our syndicated credit line. And that will help defer the need to issue equity in 2012.
And with that, I'd now like to turn the call over to Bob.
