Second Quarter 2012 Results

Continuing Operations:

The table below sets forth a comparison of the second quarter diluted earnings per share from continuing operations by business segment:

Water

For the three months ended June 30, 2012, fully diluted earnings from the water operations of AWR’s Golden State Water Company (“GSWC”) subsidiary increased by $0.05 per share to $0.56 per share as compared to $0.51 per share for the three months ended June 30, 2011. It is worth noting that 2012 is the last year of a rate case cycle for all of GSWC’s water regions, and rate increases are typically lowest in the final year of a rate case cycle. Items impacting the comparability of the two periods are detailed below:

• An increase in the water gross margin of approximately $305,000, or $0.01 per share, during the three months ended June 30, 2012 as compared to the same period in 2011 due to third year rate increases for Regions II and III approved by the California Public Utilities Commission (“CPUC”) effective January 1, 2012.
• An increase in operating expenses (other than supply costs) by approximately $1.0 million, or $0.03 per share, due primarily to increases in depreciation expense resulting from additions to utility plant, conservation related costs, and employee related costs.
• An overall decrease in interest expense (net of interest income) of $1.3 million, or $0.04 per share, due primarily to lower short-term bank borrowings and the recording of a $381,000 reduction in interest expense in connection with the CPUC’s final decision on the water cost of capital proceeding. In addition, included in the three months ended June 30, 2011 results were interest charges totaling $553,000 related to the redemption of $22.0 million of GSWC’s 7.65% Medium-Term Notes, which did not recur in 2012.
• A decrease in the effective tax rate increased earnings by approximately $0.03 per share during the second quarter of 2012 primarily resulting from changes between book and taxable income that are treated as flow-through adjustments in accordance with regulatory requirements, and changes in certain permanent items.

Electric

For the three months ended June 30, 2012, fully diluted earnings from GSWC’s electric operations were $0.04 per share, an increase of $0.01 per share compared to the same period in the prior year due to an increase in the electric gross margin, partially offset by increased operating expenses.

Contracted Services

For the three months ended June 30, 2012, fully diluted earnings from AWR’s contracted services subsidiary, American States Utility Services, Inc. (“ASUS”), increased by $0.05 per share to $0.19 per share as compared to the same period in 2011 primarily due to an increase in construction activities and favorable changes in cost estimates at the Fort Bragg military base in North Carolina. ASUS serves Fort Bragg under a 50-year privatization contract with the U.S. government.

Discontinued Operations:

On May 31, 2011, AWR completed the sale of Chaparral City Water Company (“CCWC”) and recorded a gain, net of taxes and transaction costs, of $0.12 per share. Excluding the gain on sale, the operation of CCWC during the three months ended June 30, 2011 resulted in earnings of $0.05 per share.

Year-to-Date 2012 Results

Basic and fully diluted earnings per share for the six months ended June 30, 2012 were $1.33 and $1.32, respectively, compared to $1.25 per share on a basic and fully diluted basis, for the six months ended June 30, 2011. Basic and diluted earnings per share from continuing operations for the six months ended June 30, 2012 were also $1.33 and $1.32, respectively, compared to $1.05 per share on a basic and fully diluted basis, for the six months ended June 30, 2011. This represents a 26% increase over the prior year in fully diluted earnings per share from continuing operations.

Continuing Operations:

The table below sets forth a comparison of the year-to-date diluted earnings per share contribution from continuing operations by business segment:

Water

Fully diluted earnings contributed by GSWC’s water operations increased by $0.03 per share, to $0.83 per share for the six months ended June 30, 2012, as compared to $0.80 per share for the six months ended June 30, 2011, primarily due to:

• An increase in the water gross margin of $2.1 million, or $0.07 per share, during the six months ended June 30, 2012 primarily as the result of CPUC-approved third year rate increases for Regions II and III effective January 1, 2012.
• An increase in operating expenses (other than supply costs) by approximately $2.8 million, or $0.09 per share, due primarily to increases in: (i) depreciation expense of $1.3 million resulting from additions to utility plant, and (ii) other operation expenses of $1.2 million due, in large part, to higher labor and other employee benefits, conservation costs and bad debt expense.
• An overall decrease in interest expense (net of interest income) of approximately $1.0 million, or $0.03 per share, primarily due to debt redemption costs incurred in 2011 and a true-up of interest expense as a result of the water cost of capital final decision, as previously discussed.
• A decrease in the effective income tax rate during the six months ended June 30, 2012 as compared to the same period in 2011, increasing earnings by approximately $0.02 per share primarily resulting from changes between book and taxable income that are treated as flow-through adjustments in accordance with regulatory requirements, and changes in certain permanent items.

Electric

For the six months ended June 30, 2012, fully diluted earnings from GSWC’s electric operations increased by $0.08 per share as compared to the same period in 2011, due primarily to: (i) the CPUC’s approval of GSWC’s application to recover $1.2 million, or $0.04 per share, in legal and outside services costs incurred from September 2007 through March 2011 in connection with its efforts to procure renewable energy resources, (ii) an increase in the electric gross margin of $1.1 million, or $0.03 per share, and (iii) a decrease in the effective income tax rate increasing earnings by approximately $0.01 per share.

Contracted Services

For the six months ended June 30, 2012, fully diluted earnings from ASUS increased by $0.16 per share as compared to the same period in 2011 due primarily to an increase in construction activities at Fort Bragg in North Carolina and significant progress made on a major water and wastewater pipeline replacement project as a result of better than expected weather conditions at Fort Bragg during the first several months of 2012. This project is estimated to be completed in early 2014.

Discontinued Operations:

On May 31, 2011, AWR completed the sale of Chaparral City Water Company (“CCWC”) and recorded a gain, net of taxes and transaction costs, of $0.12 per share. Excluding the gain on sale, the operation of CCWC during the first five months of 2011 resulted in earnings of $0.08 per share.

Regulatory Matters

In July 2012, the CPUC issued a final decision on GSWC’s cost of capital proceeding filed in May 2011. The decision approves the settlement agreement entered into between GSWC, along with three other California water utilities, and the CPUC’s Division of Ratepayer Advocates (“DRA”) in November 2011. The approved settlement authorizes a Return on Equity (“ROE”) of 9.99% and a rate-making capital structure for GSWC of 55% equity and 45% debt. The weighted cost of capital (return on rate base), with an updated embedded debt cost and the authorized ROE, is 8.64%. The new rate of return authorized by the CPUC’s final decision will be implemented into water rates retroactive to January 1, 2012. The CPUC decision also authorized GSWC to continue the Water Cost of Capital Mechanism (“WCCM”). The WCCM adjusts ROE and rate of return on rate base between the three-year cost of capital proceedings only if there is a positive or negative change of more than 100 basis points in the average of the Moody’s Aa utility bond rate as measured over the period October 1 through September 30. If the average Moody’s rate for this period changes by over 100 basis points from the benchmark, the ROE will be adjusted by one half of the difference. For the first ten months of the period, the rate has declined by more than 100 basis points from the benchmark. Based upon this data, at this time GSWC expects that it will have to lower its ROE by about 50 to 60 basis points, effective January 1, 2013.

On June 21, 2012, GSWC filed a motion to adopt a settlement agreement between GSWC, the DRA, and The Utility Reform Network (“TURN”) in connection with the water General Rate Case (“GRC”) filing made in July 2011. The proposed settlement, if approved by the CPUC, resolves almost all of the issues in the GRC application and would generate approximately $9 million in additional annual revenues starting in 2013 as compared to 2012 adopted revenues. The proposed rate increases for 2014 over 2013 are $8 million or 3%, and the 2015 proposed rate increases over 2014 amount to $6.5 million, or 2%. While the increase in 2013 revenues would be approximately $9 million under the settlement agreement, the increase in the settled water gross margin is approximately $18 million, or 8.4%, when compared to the 2012 adopted water gross margin. Supply costs, which are a pass-through, are projected to decrease by $9 million in 2013 as compared to 2012 adopted supply costs resulting primarily from lower customer consumption as compared to 2012 adopted consumption levels. In addition, the CPUC requested GSWC, DRA and TURN to file additional testimony to justify the reasonableness of the Water Revenue Adjustment Mechanism (“WRAM”) and address the CPUC’s questions regarding the WRAM. In July 2012, all three parties filed additional testimony addressing the WRAM. The settlement agreement for the GRC is subject to an acceptable resolution regarding the WRAM matter.

Contracted Services

During the second quarter of 2012, the U.S. government reached an agreement with ASUS on the first price redetermination for Andrews Air Force Base in Maryland. A final modification of the contract for the funding is pending the U.S. government’s approval. Price redeterminations for Fort Bliss, Fort Jackson, Fort Bragg, and the military bases in Virginia have been filed and are under review by the U.S. government.

Non-GAAP Financial Measures

This press release includes a discussion on water and electric gross margins, which are computed by taking total water and electric revenues, less total supply costs. The discussion also includes AWR’s operations in terms of diluted earnings per share by business segment, which is each business segment’s earnings divided by the Company’s weighted average number of diluted shares. These items are derived from consolidated financial information but are not presented in our financial statements that are prepared in accordance with Generally Accepted Accounting Principles (“GAAP”) in the United States.
