The accompanying Consolidated Balance Sheet of American Water Works Company, Inc. and Subsidiary Companies (the “Company”) at June 30, 2013, the Consolidated Statements of Operations and Comprehensive Income for the three and six months ended June 30, 2013 and 2012, the Consolidated Statements of Cash Flows for the six months ended June 30, 2013 and 2012, and the Consolidated Statements of Changes in Stockholders’ Equity for the six months ended June 30, 2013 and 2012, are unaudited, but reflect all adjustments, which are, in the opinion of management, necessary to present fairly the consolidated financial position, the consolidated changes in stockholders’ equity, the consolidated results of operations and comprehensive income, and the consolidated cash flows for the periods presented. All adjustments are of a normal, recurring nature, except as otherwise disclosed. Because they cover interim periods, the unaudited consolidated financial statements and related notes to the consolidated financial statements do not include all disclosures and notes normally provided in annual financial statements and, therefore, should be read in conjunction with the Company’s Consolidated Financial Statements and related Notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the year, due primarily to the seasonality of the Company’s operations.

Certain reclassifications have been made to previously reported data to conform to the current presentation.

The following recently issued accounting standards have been adopted by the Company and have been included in the consolidated results of operations, financial position or footnotes of the accompanying Consolidated Financial Statements:

In December 2011, the Financial Accounting Standards Board (“FASB”) issued accounting guidance to amend the existing disclosure requirements for offsetting financial assets and liabilities to enhance current disclosures, as well as to improve comparability of balance sheets prepared under U.S. Generally Accepted Accounting Principles (“GAAP”) and International Financial Reporting Standards (“IFRS”). In January 2013, the FASB issued additional guidance on the scope of these disclosures. The revised disclosure guidance applies to derivative instruments and securities borrowing and lending transactions that are either offset in the financial statements or subject to an enforceable master netting arrangement or similar agreement. The revised disclosure guidance is effective on a retrospective basis for interim and annual periods beginning January 1, 2013. As this guidance provides for additional disclosure requirements only, the adoption of this guidance did not have an impact on the Company’s results of operations, financial position or cash flows.

In July 2012, the FASB updated the accounting guidance related to testing indefinite-lived intangible assets for impairment. This update permits an entity to perform a qualitative assessment to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test under current guidance. This update is effective for annual and interim impairment tests performed by the Company beginning on January 1, 2013. The adoption of this guidance did not have an impact on the Company’s results of operations, financial position or cash flows.

In February 2013, the FASB updated accounting guidance to add new disclosure requirements for items reclassified out of accumulated other comprehensive income. The update does not change the current requirements for reporting net income or other comprehensive income in financial statements. However, the amendments require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional detail about those amounts. The amendments are required to be applied prospectively for interim and annual reporting periods beginning January 1, 2013. As this guidance provides for additional disclosure requirements only, the adoption of this guidance did not have an impact on the Company’s results of operations, financial position or cash flows.

Presentation of an Unrecognized Tax Benefit When a Net Operating Loss (“NOL”) or Tax Credit Carryforward Exists

In July 2013, the FASB updated the income tax accounting guidance to resolve diversity in presentation by addressing when an entity should present unrecognized tax benefits on a net basis if there are available NOL or tax credit carryforwards. The update requires an entity to net unrecognized tax benefits against the deferred tax assets for same-jurisdiction NOL or similar tax loss carryforwards or tax credit carryforwards. Gross presentation will be required only if such carryforwards are not available or would not be used by the entity to settle any additional income taxes resulting from disallowance of the uncertain tax position. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The amendments are required to be applied prospectively to all unrecognized tax benefits that exist at the effective date and retrospective application is permitted. Early adoption is permitted and the Company adopted this guidance effective June 30, 2013. (See Note 8)

The following recently announced accounting standards are not yet required to be adopted by the Company or included in the consolidated results of operations, financial position or footnotes of the Company:

In February 2013, the FASB issued guidance for the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date. Examples of obligations within the scope of the updated guidance include debt arrangements, other contractual obligations and settled litigation and judicial rulings. The update requires an entity to measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date as the sum of the following: (a) the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors and (b) any additional amount the reporting entity expects to pay on behalf of its co-obligors. The updated guidance also includes additional disclosures regarding the nature and amount of the obligation as well as other information about those obligations. The update is effective on a retrospective basis for interim and annual periods beginning January 1, 2014. Early adoption is permitted. The Company is evaluating the specific provisions of the updated guidance, but does not expect the adoption of this guidance to have a significant impact on the Company’s results of operations, financial position or cash flows.

In June 2013, the FASB issued guidance for a parent’s accounting for the cumulative translation adjustment upon derecognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. The amendments resolve differing views in practice and apply to the release of the cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or a business within a foreign entity. The update is effective prospectively for interim and annual periods beginning January 1, 2014. Early adoption is permitted. The Company does not expect the adoption of the updated guidance to have a significant impact on its results of operations, financial position or cash flows.

Inclusion of the Fed Funds Effective Swap Rate as a Benchmark Interest Rate for Hedge Accounting Purposes

In July 2013, the FASB updated the derivatives and hedging accounting guidance to provide for the inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate (“OIS”)) as a US benchmark interest rate for hedge accounting purposes, in addition to interest rates on direct Treasury obligations of the US government (“UST”) and the London Interbank Offered Rate (“LIBOR”). The amendment also removes the restriction on using different benchmark rates for similar hedges. The update is effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17, 2013. The adoption of this guidance is not expected to have a significant impact on the Company’s results of operations, financial position or cash flows.

As of June 30, 2013, the Company closed on six acquisitions of various regulated water and wastewater systems for a total aggregate purchase price of $4,602. Assets acquired, principally plant, totaled $5,901. Liabilities assumed, primarily contributions in aid of construction, totaled $1,299.

As part of the Company’s strategic review of its business investments, it entered into agreements to sell its Arizona, New Mexico and Ohio subsidiaries. In January 2012, the Company completed the sale of its Arizona and New Mexico subsidiaries. Initial sales proceeds were $461,057, and the Company recorded no gain or loss at the time of the sale closing. In May 2012, the Company

completed the sale of its Ohio subsidiary. Sales proceeds at closing totaled $101,083. The Company recorded a pretax loss on sale of $5,166 in the second quarter of 2012, primarily due to pension settlement costs calculated at closing.

A summary of discontinued operations presented in the Consolidated Statements of Operations and Comprehensive Income follows:

Provision for income taxes includes the recognition of tax expense related to the difference between the tax basis and book basis of assets upon the sale of Arizona, New Mexico and Ohio that resulted in taxable gains, since an election was made under Section 338(h)(10) of the Internal Revenue Code to treat the sales as asset sales.

The Company’s annual goodwill impairment test is conducted at November 30 of each calendar year. Interim reviews are performed when the Company determines that a triggering event that would more likely than not reduce the fair value of a reporting unit below its carrying value has occurred.

The following table summarizes the six-month changes in goodwill of the Company’s continuing operations by reporting unit:

In March 2010, the Company established American Water Stock Direct, a dividend reinvestment and direct stock purchase plan (the “DRIP”). Under the DRIP, stockholders may reinvest cash dividends and purchase additional Company common stock, up to certain limits, through a transfer agent without commission fees. The Company’s transfer agent may buy newly issued shares directly from the Company or shares held in the Company’s treasury. The transfer agent may also buy shares in the public markets or in privately negotiated transactions. Purchases generally will be made and credited to DRIP accounts once each week. As of June 30, 2013, there were 4,685 shares available for future issuance under the DRIP.

The following table summarizes information regarding issuances under the DRIP for the six months ended June 30, 2013 and 2012:

Cash dividend payments made during the three–month periods ended March 31 and June 30 were as follows:

On July 30, 2013, the Company declared a quarterly cash dividend of $0.28 per share payable on September 3, 2013 to all shareholders of record as of August 19, 2013.

The following table presents changes in accumulated other comprehensive income (loss) by component, net of tax, for the six months ended June 30, 2013:

The Company does not reclassify the amortization of defined benefit pension cost components from accumulated other comprehensive income (loss) directly to net income in its entirety. These accumulated other comprehensive income components are included in the computation of net periodic pension cost. (See Note 9)

The Company has granted stock option and restricted stock unit awards to non-employee directors, officers and other key employees of the Company pursuant to the terms of its 2007 Omnibus Equity Compensation Plan (the “Plan”). As of June 30, 2013, a total of 9,559 shares were available for grant under the Plan. Shares issued under the Plan may be authorized-but-unissued shares of Company stock or reacquired shares of Company stock, including shares purchased by the Company on the open market for purposes of the Plan.

The Company recognizes compensation expense for stock awards over the vesting period of the award. The following table presents stock-based compensation expense recorded in operation and maintenance expense in the accompanying Consolidated Statements of Operations and Comprehensive Income for the three and six months ended June 30, 2013 and 2012:

There were no significant stock-based compensation costs capitalized during the six months ended June 30, 2013 and 2012, respectively.

In the first six months of 2013, the Company granted non-qualified stock options to certain employees under the Plan. The stock options vest ratably over the three-year service period beginning January 1, 2013. These awards have no performance vesting conditions and the grant date fair value is amortized through expense over the requisite service period using the straight-line method.

The following table presents the weighted-average assumptions used in the Black-Scholes option-pricing model and the resulting weighted-average grant date fair value per share of stock options granted through June 30, 2013:

Stock options granted under the Plan have maximum terms of seven years, vest over periods ranging from one to three years, and are granted with exercise prices equal to the market value of the Company’s common stock on the date of grant. As of June 30, 2013, $3,688 of total unrecognized compensation cost related to the non-vested stock options is expected to be recognized over the weighted-average period of 1.6 years.

The table below summarizes stock option activity for the six months ended June 30, 2013:

The following table summarizes additional information regarding stock options exercised during the six months ended June 30, 2013 and 2012:

During 2010, the Company granted selected employees 255 restricted stock units with internal performance measures and, separately, certain market thresholds. These awards vested in January 2013. The terms of the grants specified that if certain performance on internal measures and market thresholds were achieved, the restricted stock units would vest; if performance were surpassed, up to 175% of the target awards would be distributed; and if performance thresholds were not met, awards would be cancelled. In January 2013, an additional 148 restricted stock units were granted and distributed because performance was exceeded and 19 restricted stock units were cancelled because performance thresholds were not met.

In the first six months of 2013, the Company granted restricted stock units, both with and without performance conditions, to certain employees and non-employee directors under the Plan. The restricted stock units without performance conditions vest ratably over the three-year service period beginning January 1, 2013 and the restricted stock units with performance conditions vest ratably over the three-year performance period beginning January 1, 2013 (the “Performance Period”). Distribution of the performance shares is contingent upon the achievement of internal performance measures and, separately, certain market thresholds over the Performance Period. The restricted stock units granted with service-only conditions and those with internal performance measures are valued at the market value of the Company’s common stock on the date of grant. The restricted stock units granted with market conditions are valued using a Monte Carlo model.

Weighted-average assumptions used in the Monte Carlo simulation are as follows for restricted stock units with market conditions granted through June 30, 2013:

The grant date fair value of the restricted stock unit awards that vest ratably and have market and/or performance and service conditions is amortized through expense over the requisite service period using the graded-vesting method. Restricted stock units that have no performance conditions are amortized through expense over the requisite service period using the straight-line method. As of June 30, 2013, $8,559 of total unrecognized compensation cost related to the non-vested restricted stock units is expected to be recognized over the weighted-average remaining life of 1.4 years.

The table below summarizes restricted stock unit activity for the six months ended June 30, 2013:

The following table summarizes additional information regarding restricted stock units distributed during the six months ended June 30, 2013 and 2012:

If dividends are declared with respect to shares of the Company’s common stock before the restricted stock units are distributed, the Company credits a liability for the value of the dividends that would have been paid if the restricted stock units were shares of Company common stock. When the restricted stock units are distributed, the Company pays the participant a lump sum cash payment equal to the value of the dividend equivalents accrued. The Company accrued dividend equivalents totaling $200 and $399 to retained earnings during the six months ended June 30, 2013 and 2012, respectively.

Under the Nonqualified Employee Stock Purchase Plan (the “ESPP”), employees can use payroll deductions to acquire Company stock at the lesser of 90% of the fair market value of (a) the beginning or (b) the end of each three-month purchase period. As of June 30, 2013 there were 1,419 shares of common stock reserved for issuance under the ESPP. During the six months ended June 30, 2013, the Company issued 55 shares under the ESPP.

The Company primarily issues long-term debt to fund capital expenditures at the regulated subsidiaries. The components of long-term debt are as follows:

	Rate		Weighted Average Rate			Maturity Date	June 30, 2013		December 31, 2012

The Company also assumed $103 of debt via an acquisition in the second quarter of 2013.

The following long-term debt was retired through optional redemption or payment at maturity during 2013:

The Company has an interest-rate swap to hedge $100,000 of its 6.085% fixed-rate debt maturing 2017. The Company pays variable interest of six-month LIBOR plus 3.422%. The swap is accounted for as a fair-value hedge and matures with the fixed-rate debt in 2017.

The following table provides a summary of the derivative fair value balance recorded by the Company and the line item in the Consolidated Balance Sheets in which such amount is recorded:

For derivative instruments that are designated and qualify as fair-value hedges, the gain or loss on the hedge instrument as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in current net income. The Company includes the gain or loss on the derivative instrument and the offsetting loss or gain on the hedged item in interest expense as follows:

Short-term debt consists of commercial paper borrowings totaling $466,462 (net of discount of $38) at June 30, 2013 and $269,985 (net of discount of $15) at December 31, 2012.

The Company’s estimated annual effective tax rate for the six months ended June 30, 2013 was 39.8% compared to 40.2% for the six months ended June 30, 2012, excluding various discrete items.

The Company’s actual effective tax rates on continuing operations were as follows:

Included in 2013 are discrete items including $3,274 of tax benefits associated with an entity reorganization within the Company’s Market-Based segment that allowed for the utilization of state net operating loss carryforwards and the release of a valuation allowance.

The Company adopted updated income tax accounting guidance at June 30, 2013, and as a result, reclassified $74,360 of unrecognized tax benefit from other long-term liabilities to deferred income taxes at December 31, 2012 to conform to the current presentation in the accompanying Consolidated Balance Sheets.

The Company contributed $45,500 to its defined benefit pension plans in the first six months of 2013 and expects to contribute $21,275 during the balance of 2013. In addition, the Company contributed $13,993 for the funding of its other postretirement plans in the first six months of 2013 and expects to contribute $13,993 during the balance of 2013.

The Company is routinely involved in legal actions incident to the normal conduct of its business. At June 30, 2013, the Company has accrued approximately $2,000 as probable costs and it is reasonably possible that additional losses could range up to $31,700 for these matters. For certain matters, the Company is unable to estimate possible losses. The Company believes that damages or settlements recovered by plaintiffs in such claims or actions, if any, will not have a material adverse effect on the Company’s results of operations, financial position or cash flows.

The Company enters into agreements for the provision of services to water and wastewater facilities for the United States military, municipalities and other customers. The Company’s military services agreements expire between 2051 and 2060 and have remaining performance commitments as measured by estimated remaining contract revenue of $1,904,304 at June 30, 2013. The military contracts are subject to customary termination provisions held by the U.S. Federal Government prior to the agreed upon contract expiration. The Company’s Operations and Maintenance agreements with municipalities and other customers expire between 2013 and 2048 and have remaining performance commitments as measured by estimated remaining contract revenue of $970,180 at June 30, 2013. Some of the Company’s long-term contracts to operate and maintain a municipality’s, federal government’s or other party’s water or wastewater treatment and delivery facilities include responsibility for certain maintenance for some of those facilities, in exchange for an annual fee. Unless specifically required to perform certain maintenance activities, the maintenance costs are recognized when the maintenance is performed.

The Company’s water and wastewater operations are subject to federal, state, local and foreign requirements relating to environmental protection, and as such, the Company periodically becomes subject to environmental claims in the normal course of business. Environmental expenditures that relate to current operations or provide a future benefit are expensed or capitalized as appropriate. Remediation costs that relate to an existing condition caused by past operations are accrued, on an undiscounted basis, when it is probable that these costs will be incurred and can be reasonably estimated. Remediation costs accrued amounted to $3,300

and $4,400 at June 30, 2013 and December 31, 2012, respectively. The accrual relates to a conservation agreement entered into by a subsidiary of the Company with the National Oceanic and Atmospheric Administration (“NOAA”) requiring the Company to, among other provisions, implement certain measures to protect the steelhead trout and its habitat in the Carmel River watershed in the state of California. The Company has agreed to pay $1,100 annually from 2010 through 2016. The Company pursues recovery of incurred costs through all appropriate means, including regulatory recovery through customer rates. The Company’s regulatory assets at June 30, 2013 and December 31, 2012 include $8,373 and $8,656, respectively, related to the NOAA agreement.

Earnings per share is calculated using the two-class method. The two-class method is an earnings allocation formula that determines earnings per share for each class of common stock and participating security. The Company has participating securities related to restricted stock units, granted under the Company’s 2007 Omnibus Equity Compensation Plan, that earn dividend equivalents on an equal basis with common shares. In applying the two-class method, undistributed earnings are allocated to both common shares and participating securities.

The following is a reconciliation of the Company’s income from continuing operations, loss from discontinued operations, net income and weighted-average common shares outstanding for calculating basic earnings per share:

	Three Months Ended June 30,					Six Months Ended June 30,
	2013		2012			2013		2012

Diluted earnings per common share is based on the weighted-average number of common shares outstanding adjusted for the dilutive effect of common stock equivalents related to the restricted stock units, stock options, and employee stock purchase plan. The dilutive effect of the common stock equivalents is calculated using the treasury stock method and expected proceeds on vesting of the restricted stock units, exercise of the stock options and purchases under the employee stock purchase plan.

The following potentially dilutive common stock equivalents were not included in the earnings per share calculations because they were anti-dilutive:

The Company used the following methods and assumptions to estimate its fair value disclosures for financial instruments:

Current assets and current liabilities—The carrying amounts reported in the accompanying Consolidated Balance Sheets for current assets and current liabilities, including revolving credit debt, due to the short-term maturities and variable interest rates, approximate their fair values.

Preferred stock with mandatory redemption requirements and long-term debt—The fair values of preferred stock with mandatory redemption requirements and long-term debt are categorized within the fair value hierarchy based on the inputs that are used to value each instrument. The fair value of long-term debt classified as Level 1 is calculated using quoted prices in active markets. Level 2 instruments are valued using observable inputs and Level 3 instruments are valued using observable and unobservable inputs. The fair values of instruments classified as Level 2 and 3 are determined by a valuation model that is based on a conventional discounted cash flow methodology and utilizes assumptions of current market rates. As a majority of the Company’s

debts do not trade in active markets, the Company calculated a base yield curve using a risk-free rate (a U.S. Treasury securities yield curve) plus a credit spread that is based on the following two factors: an average of the Company’s own publicly-traded debt securities and the current market rates for U.S. Utility A- (BBB+ at December 31, 2012) debt securities. The Company used these yield curve assumptions to derive a base yield for the Level 2 and Level 3 securities. Additionally, the Company adjusted the base yield for specific features of the debt securities including call features, coupon tax treatment and collateral for the Level 3 instruments.

The carrying amounts (including fair value adjustments previously recognized in acquisition purchase accounting) and fair values of the financial instruments are as follows:

The following table presents assets and liabilities measured and recorded at fair value on a recurring basis and their level within the fair value hierarchy as of June 30, 2013 and December 31, 2012, respectively:

Restricted funds—The Company’s restricted funds primarily represent proceeds received from financings for the construction and capital improvement of facilities and from customers for future services under operations and maintenance projects. The proceeds of these financings are held in escrow until the designated expenditures are incurred. Restricted funds expected to be released within twelve months subsequent to the balance sheet date are classified as current.

Rabbi trust investments—The Company’s rabbi trust investments consist primarily of fixed income investments from which supplemental executive retirement plan benefits are paid. The Company includes these assets in other long-term assets.

Deposits—Deposits include escrow funds and certain other deposits held in trust. The Company includes cash deposits in other current assets.

Deferred compensation obligations—The Company’s deferred compensation plans allow participants to defer certain cash compensation into notional investment accounts. The Company includes such plans in other long-term liabilities. The value of the Company’s deferred compensation obligations is based on the market value of the participants’ notional investment accounts. The notional investments are comprised primarily of mutual funds, which are based on observable market prices.

Mark-to-market derivative asset—The Company utilizes fixed-to-floating interest-rate swaps, typically designated as fair-value hedges, to achieve a targeted level of variable-rate debt as a percentage of total debt. The Company uses a calculation of future cash inflows and estimated future outflows, which are discounted, to determine the current fair value. Additional inputs to the present value calculation include the contract terms, counterparty credit risk, interest rates and market volatility.

The Company has two operating segments that are also the Company’s two reportable segments, referred to as Regulated Businesses and Market-Based Operations.

American Water Works Company, Inc. (herein referred to as “American Water” or the “Company”) is the largest investor-owned United States water and wastewater utility company, as measured both by operating revenue and population served. Our primary business involves the ownership of water and wastewater utilities that provide water and wastewater services to residential, commercial, industrial and other customers. Our Regulated Businesses that provide these services are generally subject to economic regulation by state regulatory agencies (“PUCs”) in the states in which they operate. We report the results of these businesses in our Regulated Businesses segment. We also provide services that are not subject to economic regulation by the PUCs. We report the results of these businesses in our Market-Based Operations segment. For further description of our businesses see the “Business” section found in our Form 10-K for the year ended December 31, 2012 and subsequent filings with the SEC.

You should read the following discussion in conjunction with our Consolidated Financial Statements and related Notes included elsewhere in this Quarterly Report on Form 10-Q and in our Form 10-K for the year ended December 31, 2012 filed with the SEC.

All financial information in this Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) reflects only continuing operations. As previously disclosed in our Form 10-K for the year ended December 31, 2012, as part of our portfolio optimization initiative, we entered into agreements in 2011 to sell our regulated subsidiaries in Arizona, New Mexico and Ohio. In the first quarter of 2012, we completed the divestiture of the Arizona and New Mexico subsidiaries, and on May 1, 2012, we completed the divestiture of our Ohio subsidiary. Therefore, the financial results of these entities have been presented as discontinued operations for all periods, unless otherwise noted.

For the three months ended June 30, 2013, we reported net income of $101.3 million, or diluted earnings per share (“EPS”) of $0.57 compared to $107.0 million, or diluted EPS of $0.60 for the comparable period in 2012. Income from continuing operations was $101.3 million for the second quarter of 2013 compared to $116.7 million in the second quarter of 2012. Diluted income from continuing operations per average common share was $0.57 for the second quarter of 2013 as compared to $0.66 for the second quarter of 2012.

For the six months ended June 30, 2013, our net income amounted to $158.9 million, or diluted earnings per share of $0.89 compared to $148.8 million, or diluted EPS of $0.84 for the comparable period in 2012. Income from continuing operations was $158.9 million for the six months ended June 30, 2013 compared to $165.9 million for the same period in 2012. Diluted income from continuing operations per average common share was $0.89 for the six months ended June 30, 2013 as compared to $0.94 for the first six months of 2012.

The primary factor contributing to the decrease in income from continuing operations for the three months ended June 30, 2013 compared to the same period in 2012 was lower Regulated Businesses revenue. The lower revenues were principally due to a decline in customer usage in 2013, most of which is attributable to weather. Also, adding to the decrease was higher depreciation expense, due to additional utility plant placed in service, including incremental expense of $3.3 million associated with our business transformation project, which has a much shorter depreciable life than most of our other utility plant assets. The decrease for the six months ended June 30, 2013 compared to the same period in 2012 was mainly due to higher depreciation expense of $16.6 million, with the impact

of our business transformation project accounting for approximately $6.0 million of the change. For further details, see “Consolidated Results of Operations and Variances” and “Segment Results” below.

In 2013, our goals include actively addressing regulatory lag that impacts return on our investments and promoting constructive regulatory frameworks, continuing to improve our regulated operation and maintenance (“O&M”) efficiency ratio, making efficient use of our capital and expanding both our Regulated Businesses segment through focused acquisitions and/or organic growth and our Market-Based Operations segment through core growth, expanding markets and new offerings.

We expect to file up to four general rate cases as well as file for infrastructure surcharges in 2013. Additionally, we expect, as part of our general rate case filings or in separate filings, to seek appropriate pass-through mechanisms for certain costs and forward-looking adjustments or mechanisms including those that recognize declining usage.

The progress that we have made in the first six months of 2013 with respect to these objectives is described below.

Addressing Regulatory Lag and Declining Usage. For the three months ended June 30, 2013, a number of rate increases became effective. On April 1, 2013, additional annualized revenue of $2.9 million resulting from infrastructure charges in our Pennsylvania subsidiary became effective. Also, on April 1, 2013 the second step increase of $1.4 million from our 2012 New York rate case became effective. On June 15, 2013, additional annualized revenue of $0.1 million resulting from an increase in rates in our Michigan subsidiary became effective. Additionally, on June 21, 2013 annualized revenue of $5.4 million resulting from infrastructure charges in our Missouri subsidiary became effective.

The table below provides further details of annualized revenues, assuming a constant volume, resulting from rate authorizations granted:

(a) Second step increase from the 2012 rate case became effective on April 1, 2013. Final step increase of $1.2 million will be effective on April 1, 2014.

(b) The escalation year increase of $3.5 million became effective on January 1, 2013. The attrition year increase will be effective January 1, 2014.

(c) Final step increase amounting to $2.6 million related to the 2010 Pennsylvania wastewater rate case that became effective January 1, 2013.

On July 1, 2013, additional annualized revenue of $3.7 million and $4.0 million resulting from infrastructure charges in our Pennsylvania and New Jersey subsidiaries became effective.

During the second quarter of 2013, we filed a number of general rate cases. On April 30, 2013, we filed general rate cases in Pennsylvania and Iowa requesting additional annualized revenues of $58.6 million and $6.4 million, respectively. On May 10, 2013, $2.7 million in annualized revenues of the $6.4 million requested in the Iowa rate case was put into effect as interim rates under bond and subject to refund.

On May 1, 2013, we filed a proposed application to increase rates in California and on July 1, 2013 we filed an update to that filing for a total request of $33.5 million of additional annualized revenues which includes increases in 2016 and 2017 of $8.3 million and $6.7 million, respectively.

On July 9, 2013, our West Virginia subsidiary entered into a joint stipulation for their water and wastewater general rate case that was filed on December 14, 2012. The stipulation, if approved, could provide $8.5 million in additional annualized revenue. The agreement is pending regulatory approval.

On July 27, 2013, interim rates which would provide for an additional $12.3 million of annualized revenue were put into effect subject to refund for our Kentucky subsidiary. Interim rates reflect the full increase requested as allowed by state regulations.

As of August 1, 2013, we are awaiting final orders in five states, including Iowa and Kentucky, requesting additional annualized revenues of $135.4 million. There is no assurance that all, or any portion, of these requested increases will be granted.

Continuing Improvement in O&M Efficiency Ratio for our Regulated Businesses. Our O&M efficiency ratio (a non-GAAP measure) is calculated on our Regulated Businesses’ operations and is defined as operation and maintenance expense divided by operating revenues where both operation and maintenance expense (“O&M”) and operating revenues are adjusted to eliminate the impact of purchased water. We also exclude the allocable portion of non-O&M support services costs, mainly depreciation and general taxes that are reflected in the Regulated Businesses segment as O&M costs but for consolidated financial reporting purposes are categorized within other line items in the Statement of Operations. Our operating efficiency ratio was 38.1% for the three months ended June 30, 2013, compared to 36.6% for the three months ended June 30, 2012. Our operating efficiency ratio was 40.4% for the six months ended June 30, 2013 compared to 39.7% for the same period in 2012. The change in our 2013 O&M efficiency ratio for both the three and six months ended June 30, 2013 was primarily attributable to the decrease in revenue.

We evaluate our operating performance using this measure because management believes it is a direct measure of the efficiency of our regulated operations. This information is intended to enhance an investor’s overall understanding of our operating performance. The O&M efficiency ratio is not a measure defined under GAAP and may not be comparable to other companies’ operating measures and should not be used in place of the GAAP information provided elsewhere in this report. The following table provides a reconciliation that compares operation and maintenance expense and operating revenues, as determined in accordance with GAAP, to those amounts utilized in the calculation of our O&M efficiency ratio for the three and six months ended June 30, 2013 as compared to the same period in 2012:

Making Efficient Use of Capital. We invested approximately $429.8 million in Company-funded capital improvements during the six months ended June 30, 2013.

During the second quarter of 2013, we implemented Phase II of our business transformation project in a number of our regulated subsidiaries. Phase II consists of the roll-out of a new Enterprise Asset Management system, which manages an asset’s lifecycle, and a Customer Information system, which contains all billing and payment data pertaining to our Regulated Businesses segment customers. We expect to implement Phase II in our remaining regulated subsidiaries during the fourth quarter and expect it to be substantially complete by December 31, 2013. Through June 30, 2013, we have spent $294.9 million on our business transformation project, including allowance for funds used during construction (“AFUDC”), with $37.8 million spent in 2013. Expenditures associated with this project are included in our estimated capital expenditures of $950 million for 2013.

Expanding Markets and Developing New Offerings. During the six months ended June 30, 2013, our Regulated Businesses completed the purchase of four water systems in Pennsylvania, California and Indiana and two wastewater systems in Pennsylvania and Missouri. These acquisitions added approximately 2,000 customers to our regulated operations. Also, during the first half of 2013, our Homeowner Services Group (“HOS”) announced that it expanded its water and sewer line protection programs into nine new states.

On May 2, 2013, we signed an agreement to purchase the stock of a wastewater utility company in Virginia for $12.0 million in cash plus the assumption of approximately $13.8 million in long-term debt. The acquisition is subject to regulatory approval, which is anticipated in the fourth quarter of 2013. This acquisition will add approximately 20,000 wastewater customers to our Virginia regulated operations.

The following is a discussion of the consolidated results of operations for the three and six months ended June 30, 2013 compared to the three and six months ended June 30, 2012:

Operating revenues. Consolidated operating revenues for the three months ended June 30, 2013 decreased $21.3 million, or 2.9%, compared to the same period in 2012. The variance is mainly attributable to a $19.7 million decrease in our Regulated Businesses segment mainly as a result of a decrease in demand in 2013 compared to 2012 and a $2.0 million decrease in our Market-Based Operations segment primarily due to the termination of certain municipal and industrial operations and maintenance contracts in the Contract Operations Group in 2012. For further information, see the respective “Operating Revenues” discussions within the “Segment Results.”

Operation and maintenance. Consolidated operation and maintenance (“O&M”) expense for the three months ended June 30, 2013 decreased by $4.3 million, or 1.3%, compared to the same period in 2012. Included in O&M expense for the three months ended June 30, 2013 is approximately $1.5 million in compensation related expenses attributable to the change in our Chief Financial Officer. For further discussions on the changes in our Regulated and Market-Based segments’ O&M, see the respective “Operation and Maintenance” discussions within the “Segment Results.”

Depreciation and amortization. Depreciation and amortization expense increased by $9.0 million, or 9.8%, for the three months ended June 30, 2013 compared to the same period in the prior year principally as a result of additional utility plant placed in service, including Phase I and Phase II of our business transformation project that went into service during the third quarter of 2012 and the second quarter of 2013, respectively.

General taxes. General taxes expense, which includes taxes for property, payroll, gross receipts, and other miscellaneous items, increased by $2.5 million, or 4.6%, for the three months ended June 30, 2013, compared to the same period in 2012. This increase was principally due to higher property taxes most of which is the result of incremental taxes associated with our New York acquisition in the second quarter of the prior year.

Other income (expenses). Other expenses increased by $0.8 million, or 1.1%, for the three months ended June 30, 2013 compared to the same period in the prior year. The change is primarily due to a reduction in AFUDC of $1.9 million attributable to decreased construction activities in the second quarter of 2013 compared to the same period in 2012 as well as additional amortization of deferred debt financing costs associated with the new unsecured revolving credit facility that was entered into during the fourth quarter of 2012. Partially offsetting these expenses was a reduction in interest expense of $2.0 million.

Provision for income taxes. Our consolidated provision for income taxes decreased $14.1 million, or 17.6%, to $66.5 million for the three months ended June 30, 2013. The effective tax rates for the three months ended June 30, 2013 and 2012 were 39.6% and 40.9%, respectively.

Loss from discontinued operations, net of tax. As noted above, the financial results of our regulated water and wastewater systems in Arizona, New Mexico and Ohio were classified as discontinued operations for the three months ended June 30, 2012. For the three months ended June 30, 2012, the loss from discontinued operations, net of tax included the recognition of a $5.2 million pre-tax loss on the disposition of our Ohio subsidiary and a $2.4 million pre-tax post-closing sales price adjustment in connection with the disposition of our Arizona and New Mexico subsidiaries.

Operating revenues. Consolidated operating revenues for the six months ended June 30, 2013 decreased $3.8 million, or 0.3%, compared to the same period in 2012. The variance is mainly attributable to a $15.3 million decrease in our Market-Based Operations segment related to a decline in our Contract Operations Group revenues mainly as a result of the termination of certain municipal and industrial operations and maintenance contracts in 2012, partially offset by an $11.7 million increase in our Regulated Businesses segment mainly as a result of rate increases and incremental revenues due to acquisitions, which were partially offset by reduced consumption in 2013 compared to 2012 . For further information, see the respective “Operating Revenues” discussions within the “Segment Results.”

Operation and maintenance. Consolidated operation and maintenance expense for the six months ended June 30, 2013 decreased by $2.1 million, or 0.3%, compared to the same period in 2012. As noted above, compensation related expenses of $1.5 million were recorded in the second quarter of 2013 associated with the change in our Chief Financial Officer. For further information, see the respective “Operation and Maintenance” discussions within the “Segment Results.”

Depreciation and amortization. Depreciation and amortization expense increased by $16.6 million, or 9.0%, for the six months ended June 30, 2013 compared to the same period in the prior year mainly as a result of additional utility plant placed in service, including Phase I and Phase II of our business transformation project.

General Taxes. General taxes expense increased by $5.5 million, or 4.9%, for the six months ended June 30, 2013 compared to the same period in the prior year. This increase was principally due to higher property taxes mostly related to the properties acquired in our New York acquisition in the second quarter of 2012.

Other income (expenses). Other expenses increased by $1.1 million, or 0.8%, for the six months ended June 30, 2013 compared to the same period in the prior year. The change is principally due to a reduction in AFUDC of $3.3 million attributable to decreased construction activities in the first half of 2013 compared to the same period in 2012 as well as additional amortization of deferred debt financing costs associated with the new unsecured revolving credit facility that was entered into during the fourth quarter of 2012. Partially offsetting these expense increases was a reduction in interest expense of $3.5 million associated with a reduction in the outstanding debt in addition to lower interest rates obtained on 2012 refinancings.

Provision for income taxes. Our consolidated provision for income taxes decreased $18.4 million, or 15.8%, to $97.6 million for the six months ended June 30, 2013. The effective tax rates for the six months ended June 30, 2013 and 2012 were 38.1% and 41.1%, respectively. The 2013 rate includes a $3.3 million tax benefit associated with a legal structure reorganization within our Market-Based Operations segment. This strategic restructuring allowed us to utilize state net operating loss carryforwards, which without the restructuring most likely would not have been utilized prior to their expiration.

Loss from discontinued operations, net of tax. As noted above, the financial results of our regulated water and wastewater systems in Arizona, New Mexico and Ohio were classified as discontinued operations for the six months ended June 30, 2012. For the six months ended June 30, 2012, income from discontinued operations, net of tax included the recognition of tax expense related to the difference between the tax basis and book basis of assets upon the sale of Arizona, New Mexico and Ohio that resulted in taxable gains, since an election was made under Section 338(h)(10) of the Internal Revenue Code to treat the sales as asset sales, as well as the loss on disposition of our Ohio subsidiary and the sales price adjustment in connection with the disposition of Arizona and New Mexico subsidiaries.

We have two operating segments that are also our reportable segments: the Regulated Businesses and the Market-Based Operations. We evaluate the performance of our segments and allocate resources based on several factors, with the primary measure being income from continuing operations before income taxes. Certain amounts within 2012 operating revenues and operations and maintenance expense categories have been reclassified to conform to the 2013 presentation.

The following table summarizes certain financial information for our Regulated Businesses for the periods indicated:

Operating revenues. Our primary business involves the ownership of water and wastewater utilities that provide services to residential, commercial, industrial and other customers. This business is generally subject to PUC regulation and our results of operations are impacted significantly by rates authorized by the PUCs in the states in which we operate.

Operating revenues decreased by $19.7 million, or 3.0%, for the three months ended June 30, 2013, as compared to the same period in 2012. The decrease in revenues associated with lower demand amounted to approximately $31.0 million and was primarily due to hot and dry weather conditions in the central and northeast portions of the country in 2012 versus very wet weather conditions in 2013. This decrease was partially offset by revenue increases due to rate increases obtained through rate authorizations for a number of our operating companies of $15.8 million, additional revenues associated with acquisitions of $2.2 million less a retroactive

adjustment totaling $7.2 million resulting from the issuance of a final rate order in California in the second quarter of 2012. For the six months ended June 30, 2013, operating revenues increased by $11.7 million or 1.0% as compared to the same period in 2012. The increase in revenues was primarily due to rate increases obtained through rate authorizations for a number of our regulated subsidiariess, the impact of which was approximately $37.3 million. Additional revenues of $7.2 million are associated with acquisitions, the most significant being our New York acquisition in the second quarter of 2012, and increased surcharge and amortization of balancing accounts of $6.0 million. These increases were partially offset by decreased revenues of approximately $35.8 million as a result of lower demand driven by weather variations year over year and by a regulatory adjustment of $3.4 million recorded in the prior year by our California subsidiary.

Water Services – Water service operating revenues from residential customers for the three months ended June 30, 2013 totaled $367.6 million, a $16.3 million decrease, or 4.2%, over the same period of 2012. For the six months ended June 30, 2013, these revenues decreased by $0.5 million, or 0.1%, compared to the six months ended June 30, 2012. These decreases are mainly due to a decrease in sales volume related to weather abnormalities in the eastern and midwestern operating states of hot and dry conditions in 2012 and extremely wet weather in the Northeast and Midwest portions of the country in 2013. Partially offsetting the decreases were revenue increases related to rate increases. The volume of water sold and billed to residential customers decreased by 5.7% for the three months ended June 30, 2013 to 42.7 billion gallons, from 45.3 billion gallons for the same period in 2012. For the six months ended June 30, 2013, the volume sold and billed to these customers decreased by 3.7% as compared to the same period in 2012. We believe that the majority of these decreases for both the three and six months ended June 30, 2013 was due to the weather abnormalities in 2012 and 2013.

Water service operating revenues from commercial water customers for the three months ended June 30, 2013 increased by $3.1 million, or 2.4%, to $134.0 million, compared to the same period in 2012. For six months ended June 30, 2013, these revenues

increased by $9.3 million, or 3.9%, to $246.9 million, compared to June 30, 2012. These increases are primarily due to rate increases and a billing adjustment for a certain customer in our New Jersey service area which is partially offset by decreased sales volume. The volume of water sold and billed to commercial customers decreased by 4.1% and 2.9% for the three and six months ended June 30, 2013, respectively, compared to the same periods in 2012. This decrease is mainly attributable to the implementation of our new CIS system in certain of our regulated operating subsidiaries. Because of the implementation, we made a conscious decision to increase the level of scrutiny and verification around bills being generated by the new system, in particular larger or more complex bills. Subsequently, there was a decrease in billed sales volumes and an increase in unbilled usage during the second quarter of 2013 compared to the prior year.

Water service operating revenues from industrial customers totaled $31.1 million for the three months ended June 30, 2013, a decrease of $0.3 million, or 1.1%, from those recorded for the same period in 2012, and is mainly due to a decrease in sales volume partially offset by rate increases. For the six months ended June 30, 2013, water service operating revenues from industrial customers increased $1.1 million, or 1.8%, to $59.0 million, compared to the same period of 2012 and is primarily due to rate increases. The volume of water sold and billed to industrial customers totaled 8.3 billion gallons for the three months ended June 30, 2013, a decrease of 15.2% from 9.8 billion gallons for the three months ended June 30, 2012. The volume of water sold and billed to industrial customers for the six months ended June 30, 2013 decreased 8.4% compared to the six months ended June 30, 2012. Consistent with the commercial decrease explained above, these volume decreases are mainly attributable to the implementation of our new CIS system and the increased level of bill review.

Other water revenues for the three months ended June 30, 2013 totaled $3.9 million, a decrease of $7.0 million, or 64.5%. For the six months ended June 30, 2013, these revenues decreased by $5.1 million, or 36.1%, to $9.0 million. These decreases are primarily due to a reduction in the water revenue adjustment mechanism in our California and New York subsidiaries.

Other revenues – Other revenues, which include such items as reconnection charges, initial application service fees, certain rental revenues, revenue collection services for others and similar items, decreased $0.3 million, or 2.7%, for the three months ended June 30, 2013. These revenues have increased $1.8 million, or 8.7%, for the six months ended June 30, 2013, from those recorded for the same period in 2012. This increase is primarily due to the additional surcharge revenues partially offset by decreases in revenues related to billings for others, reconnection and late fees as well as the insurance proceeds recorded in the prior year for the business interruption for our Joplin, Missouri service area affected by tornados in 2011.

Operation and maintenance. Operation and maintenance expense increased $2.3 million, or 0.8%, and $13.3 million, or 2.5%, for the three and six months ended June 30, 2013, respectively, compared to the same period in 2012. Included in these increases are incremental costs in 2013 associated with our New York acquisition, which occurred on May 1, 2012, of $1.2 million and $4.6 million, for the three and six months ended June 30, 2013, respectively.

The following table provides information regarding operation and maintenance expense for the three and six months ended June 30, 2013 and 2012, by major expense category:

For the three and six months ended June 30, 2013, production costs and employee-related costs accounted for approximately 66% and 65%, respectively, of the total Regulated Businesses’ operation and maintenance expense, compared to 68% for both of these periods in 2012. These items are discussed in more detail below.

Overall, production costs decreased for the three and six months ended June 30, 2013, compared to the same period in the prior year, as a result of lower production and sales during the second quarter of 2013.

Employee-related costs, including salaries and wages, group insurance, and pension expense, decreased $2.1 million, or 1.8%, for the three months ended June 30, 2013, compared to the same period in the prior year. These employee-related costs represent approximately 42% and 43% of operation and maintenance expense for the three months ended June 30, 2013 and 2012, respectively. These costs also decreased $4.5 million or 1.9%, for the six months ended June 30, 2013, compared to the same period in the prior year. These employee-related costs represent approximately 42% and 44%, of operation and maintenance expense for the six months ended June 30, 2013 and 2012, respectively.

The following table provides information with respect to components of employee-related costs for the three and six months ended June 30, 2013 and 2012:

The overall decrease in employee-related costs for the three and six months ended June 30, 2013, compared to the same period in 2012, was primarily due to decreased pension expense. The decrease in pension expense for the three and six months ended June 30, 2013 was primarily due to decreased contributions in certain of our regulated operating companies whose costs are recovered based on our funding policy, which is to fund at least the minimum amount required by the Employee Retirement Income Security Act of 1974. Also, adding to this decrease was the inclusion of a $1.7 million charge in both the three and six months ended June 30, 2012 resulting from the finalization of our California rate case. Also contributing to the six months ended June 30, 2013 decrease was lower group insurance expense, which was mainly attributable to higher capitalization rates and reduced headcount. Salaries and wages expense was relatively unchanged for the three and six months ended June 30, 2013, compared to 2012, with increases related to annual wage increases and increased overtime expense offset by higher capitalization rates and $2.4 million of severance-related costs included in the 2012 period.

Operating supplies and services include the day-to-day expenses of office operation, legal and other professional services, transportation expenses, information systems rental charges and other office equipment rental charges. These costs increased $8.6 million, or 18.3%, and $14.9 million, or 15.7%, for the three and six months ended June 30, 2013, respectively. The overall increase was primarily due to higher contracted services, mainly as a result of backfilling positions; the use of contractors for other specific projects; and lastly, additional incremental costs attributable to the continued maturity of our Enterprise Resource Planning system in

conjunction with the implementation of Phase I of our business transformation project. Also, contributing to the increase in operating supplies and services is the 2013 operating costs associated with the New York acquisition. Partially offsetting these increases were lower transportation expenses due to a reduction in leased vehicle costs.

Maintenance materials and supplies, which include emergency repairs as well as costs for preventive maintenance, decreased $1.8 million, or 11.1%, for the three months ended June 30, 2013, mainly due to lower tank painting in 2013 in our New Jersey subsidiary of $1.4 million. The six months ended June 30, 2013 is relatively consistent with the prior year six month costs.

Customer billing and accounting expenses, which include uncollectible accounts expense, postage and other customer related expenses, increased $1.5 million, or 14.2%, and $2.8 million, or 14.3%, for the three and six months ended June 30, 2013, respectively, compared to the same periods in the prior year, primarily due to an increase in uncollectible expense associated with an increase in our Regulated Businesses’ customer accounts receivable attributable to rate increases and an increase in the overall aging of receivables.

Other operation and maintenance expense includes casualty and liability insurance premiums and regulatory costs. For the three and six months ended June 30, 2013, the cost decreases were primarily driven by lower casualty insurance costs as a result of historical claims experience and retroactive adjustments.

Operating expenses. The increase in operating expenses, for the three and six months ended June 30, 2013, is due to the increases in operation and maintenance expense explained above, higher depreciation and amortization expense of $8.8 million and $15.8 million, respectively, and higher general tax expense of $2.1 million and $4.8 million, respectively. The increase in depreciation and amortization is primarily due to additional utility plant placed in service, including Phase I and Phase II of our business transformation project. The increases in general tax expense are primarily due to higher property taxes incurred as a result of our New York acquisition in the second quarter of 2012.

Income from continuing operations before income taxes. The $34.9 million and $26.5 million decreases, for the three and six months ended June 30, 2013, respectively, are the result of the aforementioned changes in operating revenue and operating expenses.

The following table provides financial information for our Market-Based Operations segment for the periods indicated:

Operating revenues. The net decrease in revenues is primarily attributable to a decrease in the Contract Operations Group revenues of $5.1 million and $19.8 million for the three and six months ended June 30, 2013, respectively. These decreases are predominantly related to the termination of certain municipal and industrial operations and maintenance contracts, which amount to approximately $6.9 million for the three month period and $12.6 million for the six month period. Additionally, revenues from capital project activities associated with military construction decreased $0.9 million and $10.7 million, for the three and six month periods, respectively, due to lower levels of work as compared to the prior year. Also contributing to the decreases were lower revenues in our Residuals Operations Group of $1.0 million and $0.7 million, for the three and six months ended June 30, 2013, respectively, compared to the same periods in 2012 due to lower levels of work performed. These decreases were offset by a $2.3 million increase due to price redeterminations for three of our military contracts as well as increases of $4.5 million and $5.9 million for the three and six months ended June 30, 2013, respectively, in our HOS revenues associated with contract growth, most notably in New York City.

Operation and maintenance. Operation and maintenance expense decreased $7.0 million, or 9.8%, and $15.5 million, or 11.2%, for the three and six months ended June 30, 2013, respectively.

The following table provides information regarding categories of operation and maintenance expense for the three and six months ended June 30, 2013 and 2012:

	For the three months ended June 30,										For the six months ended June 30,
	2013		2012		Increase (Decrease)			Percent			2013		2012		Increase (Decrease)			Percentage

As noted in the table above, decreases in operating supplies and services, production costs and employee-related costs were partially offset by an increase in maintenance materials and supplies and correspond with the decrease in revenues above. The decrease in production costs and employee-related costs is mostly due to the termination of certain municipal and industrial operations and maintenance contracts. The decrease in operating supplies and services is attributable to the decreased construction activity for our military contracts and is partially offset by increased HOS contracted services expense as well as printing and postage costs associated with expanding into new markets, including New York City. The increase in maintenance materials and services is primarily due to higher HOS repair costs, which is attributable to new contracts, an increase in the number of claims, as well as an increase in the average cost per claim and is partially offset by the terminated municipal and industrial operations and maintenance contracts. The decrease in the other category is mainly due to decreases in uncollectible accounts expense of $1.2 million and $1.6 million for the three and six months ended June 30, 2013, respectively. These decreases are due to improved collection experience for certain municipal and industrial operations and maintenance contracts.

Operating expense. The changes in operating expenses for the three and six months ended June 30, 2013, compared to the same periods in 2012, are primarily due to the variances in the operation and maintenance expense explained above.

Income from continuing operations before income taxes. The $4.5 million increase and $0.3 million decrease for the three and six months ended June 30, 2013, compared to the same periods in 2012, are the result of the aforementioned changes in operating revenues and operating expenses.

For a general overview of our sources and uses of capital resources, see the introductory discussion under “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Liquidity and Capital Resources,” contained in part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2012.

We believe that our ability to access the capital markets, our revolving credit facility and our cash flows from operations will generate sufficient cash to fund our short-term capital requirements. We fund liquidity needs for capital investment, working capital and other financial commitments through cash flows from operations, public and private debt offerings, commercial paper markets, and to the extent necessary, our revolving credit facility, which has a diversified group of banks. We regularly evaluate the capital markets as well as closely monitor the financial condition of the financial institutions associated with the revolving credit facility.

In order to meet our short-term liquidity needs, we, through American Water Capital Corp. (“AWCC”), our financing subsidiary, issue primarily commercial paper, which is supported by the revolving credit facility. The revolving credit facility is also used, to a limited extent, to support our issuance of letters of credit. As of June 30, 2013, AWCC had no outstanding borrowings and $28.9 million of outstanding letters of credit under the revolving credit facility. As of June 30, 2013, AWCC had $971.1 million available under the credit facility that we can use to fulfill our short-term liquidity needs, to issue letters of credit and back our $466.5 million outstanding commercial paper. We can provide no assurances that our lenders will meet their existing commitments or that we will be able to access the commercial paper or loan markets in the future on terms acceptable to us or at all.

Cash flows from operating activities primarily result from the sale of water and wastewater services and, due to the seasonality of demand, are generally greater during the third quarter of each fiscal year. Cash flows from operating activities for the six months ended June 30, 2013 were $290.2 million compared to $316.9 million for the six months ended June 30, 2012.

The following table provides a summary of the major items affecting our cash flows from operating activities for the six months ended June 30, 2013 and 2012:

Our working capital needs are primarily limited to funding the increase in our customer accounts receivable and unbilled revenues which is mainly associated with the revenue increase as a result of rate increases in our Regulated Businesses. We address this timing issue through the aforementioned liquidity funding mechanisms.

The following table provides information regarding cash flows used in investing activities for the periods indicated:

Cash flows used in investing activities for the six months ended June 30, 2013 was $459.4 million compared to cash flows provided by investing activities of $29.7 million for the six months ended June 30, 2012. The variance from 2012 to 2013 is mainly attributable to the fact that the 2012 amount included proceeds received from the sale of our Arizona and New Mexico subsidiaries. Also, reflected in the 2012 amount was the purchase of seven regulated water systems in New York. The decrease in net capital expenditure of $46.5 million is principally due to a reduction in our capital spending for our business transformation project.

Our financing activities, primarily focused on funding construction expenditures, include the issuance of long-term and short-term debt, primarily through AWCC. We intend to access the capital markets on a regular basis, subject to market conditions. In addition, new infrastructure may be financed with customer advances and contributions for construction (net of refunds).

The following table provides information on long-term debt that was issued during the first six months of 2013:

Proceeds from the above issuances were received from Pennsylvania Infrastructure Investment Authority and will be used to fund certain specified projects. We also assumed $0.1 million of debt via acquisition in the second quarter of 2013.

The following long-term debt was retired through optional redemption, sinking fund provisions or payment at maturity during the first six months of 2013:

From time to time, and as market conditions warrant, we may engage in additional long-term debt retirements via tender offers, open market repurchases or other viable transactions.

The following table provides information as of June 30, 2013 regarding letters of credit sub-limits under our revolving credit facility and available funds under the revolving credit facility, as well as outstanding amounts of commercial paper and borrowings under the revolving credit facilities.

The weighted-average interest rate on short-term borrowings for the three months ended June 30, 2013 and 2012 was approximately 0.35% and 0.49%, respectively, and 0.38% and 0.51% for the six months ended June 30, 2013 and 2012, respectively.

The following table provides information regarding our capital structure for the periods presented:

Our debt agreements contain financial and non-financial covenants. To the extent that we are not in compliance, we or our subsidiaries may be restricted in the ability to pay dividends, issue new debt or access our revolving credit facility. We were in compliance with our covenants as of June 30, 2013. Our failure to comply with restrictive covenants under our credit facility could accelerate repayment obligations. Our long-term debt indentures contain a number of covenants that, among other things, limit the Company from issuing debt secured by the Company’s assets, subject to certain exceptions.

Certain long-term notes and the revolving credit facility require us to maintain a ratio of consolidated debt to consolidated capitalization of not more than 0.70 to 1.00. As of June 30, 2013, our ratio was 0.56 to 1.00 and therefore we were in compliance with the covenant.

Our access to the capital markets, including the commercial paper market, and respective financing costs in those markets, is directly affected by securities ratings of the entity that is accessing the capital markets. We primarily access the capital markets, including the commercial paper market, through AWCC. However, we also issue debt through our regulated subsidiaries, primarily in the form of tax exempt securities, to lower our overall cost of debt.

On May 24, 2013, Standard & Poor’s Ratings Service, which we refer to as S & P, upgraded its corporate credit rating to A- on AWCC and American Water and AWCC’s “A2” short term rating. On that date, they also confirmed its stable rating outlook for American Water and AWCC. On May 29, 2013, Moody’s upgraded its rating outlook for both American Water and AWCC from Baa2 to Baa1 and revised its rating outlook to stable.

The following table shows the Company’s securities ratings as of June 30, 2013:

A security rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time by the assigning rating agency, and each rating should be evaluated independently of any other rating. Security ratings are highly dependent upon our ability to generate cash flows in an amount sufficient to service our debt and meet our investment plans. We can provide no assurances that our ability to generate cash flows is sufficient to maintain our existing ratings. None of our borrowings are subject to default or prepayment as a result of the downgrading of these security ratings, although such a downgrading could increase fees and interest charges under our credit facility.

As part of the normal course of business, we routinely enter into contracts for the purchase and sale of water, energy, fuels and other services. These contracts either contain express provisions or otherwise permit us and our counterparties to demand adequate assurance of future performance when there are reasonable grounds for doing so. In accordance with the contracts and applicable contract law, if we are downgraded by a credit rating agency, especially if such downgrade is to a level below investment grade, it is possible that a counterparty would attempt to rely on such a downgrade as a basis for making a demand for adequate assurance of future performance, which could include a demand that we provide collateral to secure our obligations. We do not expect that our posting of collateral would have a material adverse impact on our results of operations, financial position or cash flows.

Our board of directors’ practice has been to distribute to our shareholders a portion of our net cash provided by operating activities as regular quarterly dividends, rather than retaining that cash for other purposes. Since the dividends on our common stock will not be cumulative, only declared dividends will be paid.

On June 3, 2013, the Company made cash dividend payments of $0.28 per share to all shareholders of record as of May 24, 2013. In order to provide an opportunity for our shareholders to take advantage of lower 2012 tax rates, the cash dividend payment that would have historically been paid in March 2013 was paid in December 2012. In March and June 2012, we made cash dividend payments of $0.23 per share to all shareholders of record as of February 3, 2012 and April 20, 2012, respectively.

On July 30, 2013, our board of directors declared a quarterly cash dividend payment of $0.28 per share payable on September 3, 2013 to all shareholders of record as of August 19, 2013.

There have been no significant changes to our market risk since December 31, 2012. For a discussion of our exposure to market risk, refer to Part II, Item 7A. “Quantitative and Qualitative Disclosures about Market Risk,” contained in our Annual Report on Form 10-K for the year ended December 31, 2012.

Our financial condition, results of operations and cash flows are impacted by the methods, assumptions and estimates used in the application of critical accounting policies. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Estimates,” in our Form 10-K for the year ended December 31, 2012 filed with the SEC for a discussion of our critical accounting policies.

See Part I, Item 1 – Financial Statements (Unaudited) – Note 2 – New Accounting Pronouncements in this Quarterly Report on Form 10-Q for a discussion of new accounting standards recently adopted or pending adoption.

We are subject to market risks in the normal course of business, including changes in interest rates and equity prices. For further discussion of market risks see “Market Risk” in Part I, Item 2 – Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of June 30, 2013, our disclosure controls and procedures were effective at a reasonable level of assurance. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

On May 20, 2013, we implemented the Enterprise Asset Management system and the Customer Information system modules of our ERP, SAP ECC 6.0 for certain of our Regulated operating subsidiaries.

The implementation was part of our continued focus on upgrading and enhancing our financial systems with the goals of increasing our operating efficiencies and effectiveness and controlling the costs associated with the operation of our business, all of which are important to providing quality and reliable service to our customers and communities we serve. It was not in response to any internal control deficiencies. We are in the process of testing the internal controls over financial reporting resulting from modifications to our business processes. Although efforts have been made to minimize any adverse impact on our controls, we cannot assure that all such impacts have been mitigated.

With the exception of the EAM and CIS implementations, described above, there have been no changes in our internal control over financial reporting that occurred during the three months ended June 30, 2013, that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

The following information updates and amends the information provided in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 (the “Form 10-K”) in Part I, Item 3, “Legal Proceedings:”

As described in the Form 10-K, California-American Water Company (“CAWC”) filed an application with the California Public Utilities Commission (“CPUC”) for approval of the Monterey Peninsula Water Supply Project (the “New Project”). On July 31, 2013, CAWC entered into a settlement agreement with 15 other parties that have intervened in the CPUC proceedings with respect to the New Project, including several Monterey County government entities, the Division of Ratepayer Advocates of the CPUC and several interest groups. Under the settlement agreement, the parties have agreed on several matters relating to the New Project, including, among other things, the following: cost caps for the desalination plant and certain pipeline facilities to be constructed by CAWC aggregating $295.7 million to $338.4 million, depending on the size of the desalination ultimately approved by the CPUC; the process for recovery of project costs, including cost recovery for capital (CAWC agreed to maintain a fixed equity investment in the New Project equal to approximately 27% of total costs related to the desalination plant and certain other facilities to be constructed by CAWC), and operation and maintenance costs; procedures by which CAWC may seek recovery for reasonable and prudent costs above the caps; recommended criteria the CPUC should use to determine whether CAWC should build a smaller desalination plant to accommodate CAWC’s purchase of water from the proposed Monterey Peninsula Groundwater Replenishment Project (the “GWR Project”); the development of a hydrogeologic study work plan to determine the extent, if any, to which the proposed New Project may adversely affect the Salinas River Groundwater Basin and the water supply; contingency measures if the initially proposed intake wells, brine discharge mechanisms and plant location are infeasible; and financing mechanisms for the New Project. In a separate settlement agreement among most of the same parties, the participating parties agreed on sizing of the desalination plant at 9.6 million gallons per day, if the GWR Project does not supply water to CAWC, and, if the GWR Project supplies water to CAWC, either 6.4 million gallons per day or 6.9 million gallons per day depending on discrete capacities of GWR Project water.

The settlement agreements are subject to the approval of the CPUC and will not take effect unless the CPUC determines they are reasonable within the law and the public interest, and until the CPUC certifies an environmental impact report for the proposed New Project, scheduled for June 2014. Moreover, as noted in the Form 10-K, CAWC’s ability to move forward on the New Project will be subject to extensive administrative review, including public hearings before the CPUC and testimony from intervening parties, including some that are not participants in the settlement agreements. We cannot assure that CAWC’s application for the New Project will be approved or that the New Project will be completed on a timely basis, if ever.

In addition, the Form 10-K describes CAWC’s filing of formal claim with the Marina Coast Water District (“MCWD”) seeking monetary damages from MCWD, and the Board of MCWD’s notice that it rejected CAWC’s claim. Subsequently, CAWC and MCWD entered into a tolling agreement and extension of the agreement with respect to CAWC’s claims, which toll applicable statutes of limitations and the deadline for commencement of litigation regarding CAWC’s claims until October 14, 2013.

The Form 10-K also discloses a settlement agreement between CAWC, the Monterey County Water Resources Agency (“MCWRA”) and Monterey County. On May 24, 2013, CAWC filed an application with the CPUC for approval of the settlement agreement and rate recovery on CAWC’s debt forgiveness and additional payments to MCWRA under the settlement agreement. The application is pending.

In addition to the other information set forth in this report, you should carefully consider the factors discussed in the “Risk Factors” in the Company’s Form 10-K for the year ended December 31, 2012, and our other public filings, which could materially affect our business, financial condition or future results. There have been no material changes from risk factors previously disclosed in “Risk Factors” in the Company’s Form 10-K for the year ended December 31, 2012.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned, thereunto duly authorized, on the 7th day of August, 2013.
