INTRODUCTION

FILING FORMAT

This Quarterly Report on Form 10-Q is a combined report being filed by two separate registrants: WGL Holdings, Inc. (WGL) and Washington Gas Light Company (Washington Gas). WGL is a holding company that owns all of the outstanding common stock of its subsidiaries, including Washington Gas. Except where the content clearly indicates otherwise, any reference in the report to “WGL,” “we,” “us” or “our” is to the holding company or WGL and all of its subsidiaries, including Washington Gas, on a consolidated basis.

Part I—Financial information in this Quarterly Report on Form 10-Q includes separate financial statements (i.e. balance sheets, statements of income and comprehensive income and statements of cash flows) for WGL and Washington Gas. The Notes to Consolidated Financial Statements are presented on a combined basis for both WGL and Washington Gas. The Management’s Discussion and Analysis of Financial Condition and Results of Operations (Management’s Discussion) included under Item 2 is divided into two major sections for WGL and Washington Gas.

SAFE HARBOR FOR FORWARD-LOOKING STATEMENTS

Certain matters discussed in this report, excluding historical information, include forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 with respect to the outlook for earnings, revenues and other future financial business performance or strategies and expectations. Forward-looking statements are typically identified by words such as, but not limited to, “estimates,” “expects,” “anticipates,” “intends,” “believes,” “plans” and similar expressions, or future or conditional terms such as “will,” “should,” “would” and “could.” Forward-looking statements speak only as of today, and the registrants assume no duty to update them. The following factors, among others, could cause actual results to differ materially from forward-looking statements or historical performance:


•	the level and rate at which costs and expenses are incurred and the extent to which they are allowed to be recovered from customers through the regulatory process in connection with constructing, operating and maintaining Washington Gas’ distribution system;


•	the availability of natural gas supply and interstate pipeline transportation and storage capacity;


•	the ability of natural gas producers, pipeline gatherers and natural gas processors to deliver natural gas into interstate pipelines for delivery by those interstate pipelines to the entrance points of Washington Gas’ distribution system as a result of factors beyond our control;


•	changes and developments in economic, competitive, political and regulatory conditions;


•	changes in capital and energy commodity market conditions;


•	changes in credit ratings of debt securities of WGL or Washington Gas that may affect access to capital or the cost of debt;


•	changes in credit market conditions and creditworthiness of customers and suppliers;


•	changes in relevant laws and regulations, including tax, environmental, pipeline integrity and employment laws and regulations;


•	legislative, regulatory and judicial mandates or decisions affecting business operations or the timing of recovery of costs and expenses;


•	the timing and success of business and product development efforts and technological improvements;


•	the pace of deregulation efforts and the availability of other competitive alternatives to our products and services;


•	changes in accounting principles;


•	new commodity purchase and sales contracts or financial contracts and modifications in the terms of existing contracts that may materially affect fair value calculations under derivative accounting requirements;


•	the ability to manage the outsourcing of several business processes;


•	acts of nature;


•	terrorist activities and


•	other uncertainties.

The outcome of negotiations and discussions that we may hold with other parties from time to time regarding utility and energy-related investments and strategic transactions that are both recurring and non-recurring may also affect future performance. All such factors are difficult to predict accurately and are generally beyond the direct control of the registrants.

(ii)

WGL Holdings, Inc.

Washington Gas Light Company

Accordingly, while we believe that the assumptions are reasonable, we cannot ensure that all expectations and objectives will be realized. Readers are urged to use care and consider the risks, uncertainties and other factors that could affect our business as described in this Quarterly Report on Form 10-Q. All forward-looking statements made in this report rely upon the safe harbor protections provided under the Private Securities Litigation Reform Act of 1995.

NOTE 3. SHORT-TERM DEBT

WGL and Washington Gas satisfy their short-term financing requirements through the sale of commercial paper or through bank borrowings. Due to the seasonal nature of the regulated utility and retail energy-marketing segments, short-term financing requirements can vary significantly during the year.

NOTE 6. EARNINGS PER SHARE

Basic EPS of WGL is computed by dividing net income by the weighted average number of common shares outstanding during the reported period. Diluted EPS assumes the issuance of common shares pursuant to stock-based compensation plans at the beginning of the applicable period unless the effect of such issuance would be anti-dilutive. The following table reflects the computation of our basic and diluted EPS for the three and six months ended March 31, 2015 and 2014.

NOTE 7. INCOME TAXES

As of March 31, 2015 and September 30, 2014, our uncertain tax positions were approximately $30.2 million and $32.6 million, respectively, primarily due to the change in tax accounting for repairs. If the amounts of unrecognized tax benefits are eventually realized, it would not materially impact the effective tax rate. It is reasonably possible that the amount of the unrecognized tax benefit with respect to some of WGL’s and Washington Gas’ uncertain tax positions will significantly increase or decrease in the next 12 months, however at this time, an estimate of the range of reasonably possible outcomes cannot be determined.

Under ASC Topic 740, Income Taxes, Washington Gas recognizes any accrued interest associated with uncertain tax positions in interest expense and recognizes any accrued penalties associated with uncertain tax positions in other expenses in the statements of income. At March 31, 2015, we did not have an accrual of interest expense related to uncertain tax positions. At September 30, 2014, we had a total accrual of $0.1 million of interest expense related to uncertain tax positions included in other deferred credits in the accompanying balance sheets.

WGL files a consolidated federal tax return and various other state returns. We are no longer subject to income tax examinations by the Internal Revenue Service for years ended prior to September 30, 2011. Substantially all state income tax years in major jurisdictions are closed for years ended prior to September 30, 2010.

Washington Gas charged the Maryland portion of the Medicare Part D (Med D) regulatory asset to tax expense during the fiscal year ended September 30, 2012 based on positions taken by the Maryland Public Service Commission (PSC of MD) in Washington Gas’ rate case during that fiscal year that did not permit recovery. Washington Gas received an order in the first quarter of fiscal year ended September 30, 2014 from the PSC of MD that did allow recovery of the Med D regulatory asset

over a five year amortization period beginning December 2013. Therefore, the reinstatement of the regulatory asset is reflected in the effective tax rate for the six months ended March 31, 2014.

NOTE 8. DERIVATIVE AND WEATHER-RELATED INSTRUMENTS

DERIVATIVE INSTRUMENTS

Regulated Utility Operations

Washington Gas enters into contracts that qualify as derivative instruments and are accounted for under ASC Topic 815. These derivative instruments are recorded at fair value on our balance sheet and Washington Gas does not designate any derivatives as hedges under ASC Topic 815. Washington Gas’ derivative instruments relate to: (i) Washington Gas’ asset optimization program; (ii) managing price risk associated with the purchase of gas to serve utility customers and (iii) managing interest rate risk.

Asset Optimization. Washington Gas optimizes the value of its long-term natural gas transportation and storage capacity resources during periods when these resources are not being used to physically serve utility customers. Specifically, Washington Gas utilizes its transportation capacity assets to benefit from favorable natural gas prices between different geographic locations and utilizes its storage capacity assets to benefit from favorable natural gas prices between different time periods. As part of this asset optimization program, Washington Gas enters into physical and financial derivative transactions in the form of forward, futures and option contracts with the primary objective of locking in operating margins that Washington Gas will ultimately realize. The derivatives used under this program are subject to mark-to-market accounting treatment while the capacity and transportation resources are not.

Regulatory sharing mechanisms allow the profit from these transactions to be shared between Washington Gas’ shareholders and customers; therefore, any changes in fair value are recorded through earnings, or as regulatory assets or liabilities to the extent that gains and losses associated with these derivative instruments will be included in the rates charged to customers when they are realized. Valuation changes for the portion of net profits to be retained for shareholders may cause significant period-to-period volatility in earnings from unrealized gains and losses. This volatility does not change the locked-in operating margins that Washington Gas expects to ultimately realize from these transactions through the use of its storage and transportation capacity resources.

All physically and financially settled contracts under our asset optimization program are reported on a net basis in the statements of income in “Utility cost of gas.” Total net margins recorded to “Utility cost of gas” after sharing and management fees associated with all asset optimization transactions for the three months ended March 31, 2015 was a loss of $14.0 million including an unrealized loss of $28.0 million. During the three months ended March 31, 2014 we recorded a loss of $60.4 million including an unrealized loss of $77.9 million. Total net margins recorded for the six months ended March 31, 2015 was a gain of $17.1 million including an unrealized loss of $2.9 million. During the six months ended March 31, 2014, we recorded a loss of $80.2 million including an unrealized loss of $104.1 million.

Managing Price Risk. To manage price risk associated with acquiring natural gas supply for utility customers, Washington Gas enters into forward contracts, option contracts, financial contracts and other contracts, as authorized by its regulators. These instruments are accounted for as derivative instruments. Any gains and losses associated with these derivatives are recorded as regulatory liabilities or assets, respectively, to reflect the rate treatment for these economic hedging activities.

Managing Interest-Rate Risk. Washington Gas utilizes derivative instruments that are designed to minimize the risk of interest-rate volatility associated with planned issuances of debt securities. Any gains and losses associated with these types of derivatives are recorded as regulatory liabilities or assets, respectively, and amortized in accordance with regulatory requirements, typically over the life of the newly issued debt.

Non-Utility Operations

Managing Price Risk. WGL Energy Services enters into certain derivative contracts as part of managing the price risk associated with the sale and purchase of natural gas and electricity. WGL Midstream enters into derivative contracts for the purpose of optimizing its storage and transportation capacity as well as managing the transportation and storage assets on behalf of third parties. Derivative instruments are recorded at fair value on our consolidated balance sheets. WGL Energy Services and WGL Midstream do not designate these derivatives as hedges under ASC Topic 815; therefore, changes in the fair value of these derivative instruments are reflected in the earnings of our non-utility operations and may cause significant period-to-period volatility in earnings. The storage and transportation capacities utilized by WGL Midstream are not considered to be derivative instruments, and thus they are not recorded at fair value on our consolidated balance sheets.

Notes to Condensed Consolidated Financial Statements (Unaudited)

Managing Interest-Rate Risk. WGL utilizes derivative instruments that are designed to minimize the risk of interest-rate volatility associated with future debt issuances. WGL elected cash flow hedge accounting for its interest rate derivative instruments, which settled with the issuance of the related debt issuance in the first quarter of 2015. The effective portion of the gains and losses on the hedge were recorded within other comprehensive income and are being amortized over the life of the debt (through 2044). The amortization will be minimal for fiscal 2015.

Consolidated Operations

(c) Represents the effective portion of our cash flow hedge of $(8.1) million less $(0.1) million of amortization that was reclassified to interest expense.

Collateral

WGL utilizes standardized master netting agreements, which facilitate the netting of cash flows into a single net exposure for a given counterparty. As part of these master netting agreements, cash, letters of credit and parental guarantees may be required to be posted or obtained from counterparties in order to mitigate credit risk related to both derivatives and non-derivative positions. Under WGL’s offsetting policy, collateral balances are offset against the related counterparties’ derivative positions to the extent the application would not result in the over-collateralization of those derivative positions on the balance sheet. At March 31, 2015, Washington Gas, WGL Energy Services and WGL Midstream posted $3.0 million, $16.7 million and $8.6 million, respectively, of collateral deposits with counterparties that were not offset against open and settled derivative contracts. At September 30, 2014, Washington Gas, WGL Energy Services and WGL Midstream posted $8.2 million, $5.7 million and $11.4 million, respectively, of collateral deposits with counterparties that were not offset against open and settled derivative contracts. In addition, at March 31, 2015 and September 30, 2014, Washington Gas held $0.4 million and $2.5 million, respectively of cash collateral representing an obligation to counterparties that was not offset against open and settled derivative contracts. Any collateral posted that is not offset against open and settled derivative contracts is included in “Other prepayments” in the accompanying balance sheet. Collateral received and not offset against open and settled derivative contracts is included in “Customer deposits and advance payments” in the accompanying balance sheet.

Certain derivative instruments of Washington Gas, WGL Energy Services and WGL Midstream contain contract provisions that require collateral to be posted if the credit rating of Washington Gas or WGL falls below certain levels or if counterparty exposure to WGL Energy Services or WGL Midstream exceeds a certain level. Due to counterparty exposure levels, at March 31, 2015, WGL Energy Services posted $9.0 million of collateral related to its derivative liabilities that contained credit-related contingent features. At September 30, 2014, WGL Energy Services posted $5.3 million of collateral related to these aforementioned derivative liabilities. Washington Gas and WGL Midstream were not required to post any collateral related to its derivative liabilities that contained credit-related contingent features at March 31, 2015 or September 30, 2014. The following table shows the aggregate fair value of all derivative instruments with credit-related contingent features that are in a liability position, as well as the maximum amount of collateral that would be required if the most intrusive credit-risk-related contingent features underlying these agreements were triggered on March 31, 2015 and September 30, 2014, respectively.

Washington Gas, WGL Energy Services and WGL Midstream do not enter into derivative contracts for speculative purposes.

Concentration of Credit Risk

We are exposed to credit risk from derivative instruments with wholesale counterparties, which is represented by the fair value of these instruments at the reporting date. We actively monitor and work to minimize counterparty concentration risk through various practices. At March 31, 2015, three counterparties represented over 10% of Washington Gas’ credit exposure to wholesale derivative counterparties for a total credit risk of $22.5 million; two counterparties represented over 10% of WGL Energy Services’ credit exposure to wholesale counterparties for a total credit risk of $1.2 million; and two counterparties represented over 10% of WGL Midstream’s credit exposure to wholesale counterparties for a total credit risk of $15.1 million.

WEATHER-RELATED INSTRUMENTS

Washington Gas did not use any weather-related instruments during the three and six months ended March 31, 2015 and 2014.

WGL Energy Services utilizes weather-related instruments for managing the financial effects of weather risks. These instruments cover a portion of WGL Energy Services’ estimated revenue or energy-related cost exposure to variations in heating or cooling degree days. These contracts provide for payment to WGL Energy Services of a fixed-dollar amount for every degree day over or under specific levels during the calculation period depending upon the type of contract executed. For the three months ended March 31, 2015 and 2014, WGL Energy Services recorded pre-tax gains of $4.9 million and $6.4 million, respectively, related to these contracts. For the six months ended March 31, 2015 and 2014, WGL Energy Services recorded pre-tax gains of $3.2 million and $5.4 million, respectively, related to these contracts.

NOTE 9. FAIR VALUE MEASUREMENTS

We measure the fair value of our financial assets and liabilities using a combination of the income and market approach in accordance with ASC Topic 820. These financial assets and liabilities primarily consist of derivatives recorded on our balance sheet under ASC Topic 815 and short-term investments, commercial paper and long-term debt outstanding required to be disclosed at fair value. Under ASC Topic 820, fair value is defined as the exit price, representing the amount that would be received in the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. To value our financial instruments, we use market data or assumptions that market participants would use, including assumptions about credit risk (both our own credit risk and the counterparty’s credit risk) and the risks inherent in the inputs to valuation.

Item 1—Financial Statements (continued)

Notes to Condensed Consolidated Financial Statements (Unaudited)

We enter into derivative contracts in the futures and over-the-counter (OTC) wholesale and retail markets. These markets are the principal markets for the respective wholesale and retail contracts. Our relevant market participants are our existing counterparties and others who have participated in energy transactions at our delivery points. These participants have access to the same market data as WGL. We value our derivative contracts based on an “in-exchange” premise, and valuations are generally based on pricing service data or indicative broker quotes depending on the market location. We measure the net credit exposure at the counterparty level where the right to set-off exists. The net exposure is determined using the mark-to-market exposure adjusted for collateral, letters of credit and parent guarantees. We use published default rates from Standard & Poor’s Ratings Services and Moody’s Investors Service as inputs for determining credit adjustments.

ASC Topic 820 establishes a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The three levels of the fair value hierarchy under ASC Topic 820 are described below:

Level 1.Level 1 of the fair value hierarchy consists of assets or liabilities that are valued using observable inputs based upon unadjusted quoted prices in active markets for identical assets or liabilities at the reporting date. Level 1 assets and liabilities primarily include exchange traded derivatives and securities. WGL did not have any Level 1 derivatives at March 31, 2015 or September 30, 2014.

Level 2.Level 2 of the fair value hierarchy consists of assets or liabilities that are valued using directly or indirectly observable inputs either corroborated with market data or based on exchange traded market data. Level 2 includes fair values based on industry-standard valuation techniques that consider various assumptions: (i) quoted forward prices, including the use of mid-market pricing within a bid/ask spread; (ii) discount rates; (iii) implied volatility and (iv) other economic factors. Substantially all of these assumptions are observable throughout the full term of the instrument, can be derived from observable data or are supported by observable levels at which transactions are executed in the relevant market. At March 31, 2015 and September 30, 2014, Level 2 financial assets and liabilities included energy-related derivatives such as financial contracts, options and physical forward contracts for deliveries at active market locations.

Level 3.Level 3 of the fair value hierarchy consists of assets or liabilities that are valued using significant unobservable inputs at the reporting date. These unobservable assumptions reflect our assumptions about estimates that market participants would use in pricing the asset or liability, including natural gas basis prices, annualized volatilities of natural gas prices, and electricity congestion prices. A significant change to any one of these inputs in isolation could result in a significant upward or downward fluctuation in the fair value measurement. These inputs may be used with industry standard valuation methodologies that result in our best estimate of fair value for the assets or liabilities at the reporting date.

Our Risk Analysis and Mitigation (RA&M) Group determines the valuation policies and procedures. The RA&M Group reports to WGL’s Chief Financial Officer. In accordance with WGL’s valuation policy, we may utilize a variety of valuation methodologies to fair value Level 3 derivative contracts including internally developed valuation inputs and pricing models. The prices used in our valuations are corroborated using multiple pricing sources, and we periodically conduct assessments to determine whether each valuation model is appropriate for its intended purpose. The RA&M Group also evaluates changes in fair value measurements on a daily basis.

At March 31, 2015 and September 30, 2014, Level 3 derivative assets and liabilities included: (i) physical contracts valued at illiquid market locations with no observable market data; (ii) long-dated positions where observable pricing is not available over the life of the contract; (iii) contracts valued using historical spot price volatility assumptions; (iv) valuations using indicative broker quotes for inactive market locations and (v) non-publicly traded stock warrants.

The following tables set forth financial instruments recorded at fair value as of March 31, 2015 and September 30, 2014, respectively. A financial instrument’s classification within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy.

Transfers between different levels of the fair value hierarchy may occur based on the level of observable inputs used to value the instruments from period to period. It is our policy to show both transfers into and out of the different levels of the fair value hierarchy at the fair value as of the beginning of the period. Transfers out of Level 3 during the three and six months ended March 31, 2015 were due to an increase in valuations using observable market inputs. There were no transfers in or out of Level 3 for the three and six months ended March 31, 2014.

Our money market funds are Level 1 valuations and their carrying amount approximates fair value. Other short-term investments are primarily overnight investment accounts; therefore, their carrying amount approximates fair value based on Level 2 inputs. The maturity of our commercial paper outstanding at both March 31, 2015 and September 30, 2014 is under 30 days. Due to the short term nature of these notes, the carrying cost of our commercial paper approximates fair value using Level 2 inputs. Neither WGL’s nor Washington Gas’ long-term debt is actively traded. The fair value of long-term debt was estimated based on the quoted market prices of the U.S. Treasury issues having a similar term to maturity, adjusted for the credit quality of the debt issuer, WGL or Washington Gas. Our long-term debt fair value measurement is classified as Level 3.

Non Recurring Basis

During the six months ended March 31, 2015, Washington Gas Resources recorded an impairment charge of its investment in ASDHI to its fair value using the income approach. The amount of the impairment was equivalent to the amount of the carrying value of $5.6 million and was due to management’s assumption of the current valuation and expected return from the investment. The fair value of this investment was a Level 3 measurement.

NOTE 10. OPERATING SEGMENT REPORTING

We have four reportable operating segments: regulated utility, retail energy-marketing, commercial energy systems and midstream energy services. The division of these segments into separate revenue generating components is based upon regulation, products and services. Our chief operating decision maker is our Chief Executive Officer. During the first quarter of 2015, our chief operating decision maker began evaluating segment performance based on Earnings Before Interest and Taxes (EBIT). EBIT is defined as earnings before interest and taxes from continuing operations. Items we do not include in EBIT are interest expense, intercompany financing activity, dividends on Washington Gas preferred stock, and income taxes. EBIT includes transactions between reportable segments. Additionally, we also evaluate our operating segments based on other relevant factors, such as penetration into their respective markets and return on equity.

Our four segments are summarized below.

•

Regulated Utility – The regulated utility segment is our core business. It consists of Washington Gas and Hampshire. Washington Gas provides regulated gas distribution services (including the sale and delivery of natural gas) to customers and natural gas transportation services to an unaffiliated natural gas distribution company in West Virginia under a Federal Energy Regulatory Commission (FERC) approved interstate transportation service operating agreement. Hampshire provides regulated interstate natural gas storage services to Washington Gas under a FERC approved interstate storage service tariff.


•	Retail Energy-Marketing – The retail energy-marketing segment consists of WGL Energy Services, which sells natural gas and electricity directly to retail customers in competition with regulated utilities and unregulated gas and electricity marketers.


•	Commercial Energy Systems – The commercial energy systems segment consists of WGL Energy Systems which provides clean and energy efficient solutions including commercial solar, energy efficiency and combined heat and power projects to government and commercial clients. In addition, this segment comprises the operations of WGSW, a holding company formed to invest in alternative energy assets.


•	Midstream Energy Services – The midstream energy services segment consists of WGL Midstream, which engages in acquiring, investing in, managing and optimizing natural gas storage and transportation assets.

Activities and transactions that are not significant enough on a stand-alone basis to warrant treatment as an operating segment, and that do not fit into one of our four operating segments, are aggregated as “Other Activities” in the Operating Segment Financial Information presented below. Administrative and business development activity costs associated with WGL and Washington Gas Resources are included in “Other Activities”.

(a) Operating revenues are reported gross of revenue taxes. Revenue taxes of both the regulated utility and the retail energy-marketing segments include gross receipt taxes. Revenue taxes of the regulated utility segment also include PSC fees, franchise fees and energy taxes. Operating revenue amounts in the “Eliminations” row represent total intersegment revenues associated with sales from the regulated utility segment to the retail energy-marketing segment. Midstream Energy Services’ cost of energy related sales is netted with its gross revenues.

(b) Intersegment eliminations include a timing difference between Commercial Energy Systems’ recognition of revenue for the sale of Solar Renewable Energy Credits (SRECs) to Retail Energy-Marketing and Retail Energy-Marketing’s recognition of the associated expense. Retail Energy-Marketing has recorded a portion of the SREC’s purchased as inventory to be used in future periods at which time they will be expensed.

NOTE 11. OTHER INVESTMENTS

When determining how to account for our interests in other legal entities, WGL first evaluates if we are required to apply the variable interest entity (VIE) model to the entity, otherwise the entity is evaluated under the voting interest model.

Under the VIE model, we have a controlling financial interest in a VIE (i.e. are the primary beneficiary) when we have current or potential rights that give us the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance combined with a variable interest that gives us the right to receive potentially significant benefits or the obligation to absorb potentially significant losses. When changes occur to the design of an entity, we reconsider whether it is subject to the VIE model. We continuously evaluate whether we have a controlling financial interest in a VIE.

Under the voting interest model, we generally have a controlling financial interest in an entity where we currently hold, directly or indirectly, more than 50% of the voting rights or where we exercise control through substantive participating rights. However, we consider substantive rights held by other partners in determining if we hold a controlling financial interest, and in some cases, despite owning more than 50% of the common stock of an investee, an evaluation of our rights results in the determination that we do not have a controlling financial interest. We reevaluate whether we have a controlling financial interest in these entities when our voting or substantive participating rights change.

Unconsolidated affiliates are unconsolidated VIEs and other entities evaluated under the voting interest method in which we do not have a controlling financial interest, but over which we have varying degrees of influence. Where we have significant influence, the affiliates are accounted for as equity method investments. Where we do not have significant influence, the affiliates are accounted for under the cost method. Investments in, and advances to, affiliated companies are presented on a one-line basis in the caption “Investments in unconsolidated affiliates” on our Consolidated Balance Sheet.

WGL uses the Hypothetical Liquidation at Book Value (HLBV) methodology for certain equity method investments when the capital structure of the equity investment results in different liquidation rights and priorities than what is reflected by the underlying percentage ownership interests as defined by an equity investment agreement. For investments accounted for under the HLBV method, simply applying the percentage ownership interest to GAAP net income in order to determine earnings or losses does not accurately represent the income allocation and cash flow distributions that will ultimately be received by the investors. The equity investment agreements for ASD Solar, LP (ASD), Meade Pipeline Co LLC (Meade) and Mountain Valley Pipeline, LLC (Mountain Valley) have liquidation rights and priorities that are sufficiently different from the ownership percentages that the HLBV method was deemed appropriate. The calculation may vary in its complexity depending on the capital structure and the tax considerations for the investments.

WGL applies HLBV using a balance sheet approach. A calculation is prepared at each balance sheet date to determine the amount that WGL would receive if an equity investment entity were to liquidate all of its assets (as valued in accordance with GAAP) and distribute that cash to the investors based on the contractually defined liquidation priorities. The difference between the calculated liquidation distribution amounts at the beginning and the end of the reporting period is WGL’s share of the earnings or losses from the equity investment for the period.

Variable Interest Entities

WGL has a variable interest in four investments that qualify as VIEs:


•	Meade,

WGL Holdings, Inc.

Washington Gas Light Company

Part I—Financial Information

Item 1—Financial Statements (continued)

Notes to Condensed Consolidated Financial Statements (Unaudited)


•	SunEdison,


•	Nextility and


•	ASD.

WGL previously had a variable interest through Crab Run; however, this investment was sold during the three months ended March 31, 2015. Accordingly, at March 31, 2015, the carrying amount of the investment was removed and WGL recognized a gain of $0.7 million, which was recorded in "Equity in earnings of unconsolidated affiliates" on WGL's statements of income. WGL and its subsidiaries are not the primary beneficiary for any of the above VIEs, therefore we have not consolidated any of the VIE entities. At March 31, 2015, the nature of WGL’s involvement with these investments lacks the characteristics of a controlling financial interest. WGL does not have control over any of the VIEs’ activities that are economically significant to the VIEs. In addition, WGL does not have the obligation to absorb expected losses or the right to receive expected gains that could be significant to the VIE.

Meade

In 2014, WGL through its subsidiary, WGL Midstream, entered into a limited liability company agreement and formed Meade, a Delaware limited liability company with COG Holdings LLC, Vega Midstream MPC LLC and River Road Interests LLC. Meade was formed to partner with Transcontinental Gas Pipeline Company, LLC (Williams) to invest in a regulated pipeline project called Central Penn Pipeline (Central Penn). The Central Penn will be an approximately 177-mile pipeline originating in Susquehanna County, Pennsylvania and extending to Lancaster County, Pennsylvania that will have the capacity to transport and deliver up to approximately 1.7 million dekatherms per day of natural gas.

WGL Midstream plans to invest an estimated $410.0 million for a 55% interest in Meade. WGL Midstream joins COG Holdings LLC (20% share), Vega Midstream MPC LLC (15% share) and River Road Interests LLC (10% share) in Meade. Meade is accounted for under the HLBV equity method of accounting, and any profits and losses are included in “Equity in earnings of unconsolidated affiliates” in the accompanying Consolidated Statement of Income and are added to or subtracted from the carrying amount of WGL’s investment balance. WGL Midstream held a $16.0 million equity method investment in Meade at March 31, 2015.

Our maximum financial exposure includes contributions and guarantees on behalf of WGL Midstream. Our maximum exposure to loss at March 31, 2015 was $59.4 million, which represents the minimum funding requirements owed to Williams under the Construction and Ownership Agreement should Meade terminate its agreement with Williams early.

SunEdison/Nextility

WGSW is party to two agreements to fund residential and commercial retail solar energy installations with two separate, privately held companies. WGSW has a master purchase agreement and master lease agreement with SunEdison, Inc. (SunEdison), and Nextility, Inc. (Nextility) for sale/leaseback arrangements for residential and commercial solar systems.

Our agreements with SunEdison and Nextility are accounted for as direct financing leases. WGSW records associated interest in the financing leases in “Other income (expenses)-net” line in the accompanying Consolidated Statement of Income. WGSW held a $23.5 million and $19.9 million combined investment in direct financing leases at March 31, 2015 and September 30, 2014, respectively, of which $3.3 million and $1.7 million are current receivables recorded in “Accounts Receivable” in the accompanying Consolidated Balance Sheets at March 31, 2015 and September 30, 2014, respectively.

Minimum future lease payments receivable under direct financing leases over the next five fiscal years and thereafter are as follows:



Minimum Payments Receivable for Direct Financing Leases
(In millions)
Remainder of 2015	$	2.8
2016	2.2
2017	2.1
2018	2.0
2019	1.9
Thereafter	15.9
Total	$	26.9

WGL Holdings, Inc.

Washington Gas Light Company

Part I—Financial Information

Item 1—Financial Statements (continued)

Notes to Condensed Consolidated Financial Statements (Unaudited)

Minimum payments receivable exclude $6.2 million of residual values and $2.4 million in tax credits. Associated with these investments, WGSW holds $12.0 million of unearned income on its balance sheet. The initial direct costs (incurred in FY 2012) associated with these investments was $0.7 million.

Our maximum financial exposure from solar agreements is limited to WGSW's lease payment receivables and investment contributions made to these companies. All additional future committed contributions are contingent on the projects meeting required criteria. Our exposure is offset by the owned physical assets received as part of the transaction and the quick economic return for the investment through the investment tax credit/treasury grant proceeds and accelerated depreciation.

ASD

In addition to SunEdison and Nextility, WGSW is also a limited partner in ASD, a partnership formed to own and operate a portfolio of residential solar projects, primarily rooftop photovoltaic power generation systems. As a limited partner, WGSW provided funding to the partnership but is excluded from involvement in the partnership’s operations. In January 2014, the funding commitment period expired for the partnership. WGSW’s maximum financial exposure includes contributions made to the partnership.

Our investment in ASD is accounted for under the HLBV equity method of accounting; any profits and losses are included in “Equity in earnings of unconsolidated affiliates” in the accompanying Consolidated Statement of Income and are added to or subtracted from the carrying amount of WGSW’s investment balance. WGSW held a $65.2 million equity method investment in ASD at March 31, 2015.

ASD is consolidated by the general partner, Solar Direct LLC. Solar Direct LLC is a wholly owned subsidiary of American Solar Direct Inc. (ASDI). At March 31, 2015, the carrying amount of WGSW’s investment in ASD exceeded the amount of the underlying equity in net assets by $35.9 million due to WGSW recording additions to its investment in ASD’s net assets at fair value of contributions in accordance with GAAP. This basis difference is being amortized over the life of the assets.

Non-VIE Investments

ASDHI

At September 30, 2014, Washington Gas Resources held a $5.6 million investment in American Solar Direct Holdings Inc. (ASDHI) consisting of warrants and preferred stock. During the six months ended March 31, 2015, Washington Gas Resources impaired its entire investment in ASDHI by its carrying value of $5.6 million based on management’s assumption of the current valuation and expected return from the investment.

Constitution

In 2013, WGL Midstream invested in Constitution Pipeline Company, LLC (Constitution). WGL Midstream will invest an estimated $79.0 million in the project for a 10% share in the pipeline venture over the term of the agreement. WGL Midstream joins Williams Partners L.P. (41% share), Cabot Oil and Gas Corporation (25% share) and Piedmont Natural Gas (24% share) in the project. This natural gas pipeline venture will transport natural gas from the Marcellus region in northern Pennsylvania to major northeastern markets. At March 31, 2015, WGL Midstream had invested $27.6 million in Constitution. Constitution is accounted for under the equity method of accounting; any profits and losses are included in “Equity in earnings of unconsolidated affiliates” in the accompanying Consolidated Statement of Income and are added to or subtracted from the carrying amount of WGL’s investment balance. The equity method is considered appropriate because Constitution is an LLC with specific ownership accounts and ownership between five and fifty percent resulting in WGL Midstream maintaining a more than minor influence over the partnership operating and financing policies.

Mountain Valley Pipeline

In March 2015, WGL Midstream acquired a 7% equity interest in Mountain Valley Pipeline, LLC (Mountain Valley).

The proposed pipeline to be developed, constructed, owned and operated by Mountain Valley, will transport approximately 2.0 million dekatherms of natural gas per day from a new interconnect with EQT Corporation's Equitrans system, near the MarkWest Mobley plant in Smithfield, West Virginia to Transcontinental Gas Pipeline Company LLC's Station 165 in Pittsylvania County, Virginia. The pipeline is scheduled to be in service by December 2018.

The total project investment is anticipated to be between $3.0-$3.5 billion. WGL Midstream will invest, in scheduled capital contributions through the in-service date of the pipeline, its pro rata share (based on its 7% equity interest) of project costs, which is estimated to be $230 million. In addition, WGL Midstream held a $5.8 million equity method investment in the Mountain Valley at March 31, 2015.

Notes to Condensed Consolidated Financial Statements (Unaudited)

Our maximum financial exposure includes guarantees on behalf of WGL Midstream and another partner in the venture. WGL's maximum exposure to loss due to the provided guarantees was $20.0 million at March 31, 2015 which represents a $14.0 million minimum funding requirement for WGL Midstream and a $6.0 million minimum funding requirement for another partner in the venture.

In addition, WGL Midstream entered into an agreement to finance future capital commitments of one of the other partners in the venture for up to approximately $96.0 million, which represents the estimated remaining funding requirements for that partner's 3% ownership interest in the joint venture, inclusive of the minimum funding requirement. WGL Midstream has provided funding of $2.5 million as of March 31, 2015 related to this agreement.

The balance sheet location of the investments discussed in this footnote at March 31, 2015 and September 30, 2014 are as follows:

NOTE 12. RELATED PARTY TRANSACTIONS

WGL and its subsidiaries engage in transactions during the ordinary course of business. Inter-company transactions and balances have been eliminated from the consolidated financial statements of WGL, except as described below. Washington Gas provides accounting, treasury, legal and other administrative and general support to affiliates, and files consolidated tax returns that include affiliated taxable transactions. Washington Gas bills its affiliates in accordance with regulatory requirements for the

Notes to Condensed Consolidated Financial Statements (Unaudited)

actual cost of providing these services, which approximates their market value. To the extent such billings are not paid, they are reflected in “Receivables from associated companies” on Washington Gas’ balance sheets. Washington Gas assigns or allocates these costs directly to its affiliates and, therefore, does not recognize revenues or expenses associated with providing these services.

In connection with billing for unregulated third party marketers and with other miscellaneous billing processes, Washington Gas collects cash on behalf of affiliates and transfers the cash in a reasonable time period. Cash collected by Washington Gas on behalf of its affiliates but not transferred is recorded in “Payables to associated companies” on Washington Gas’ balance sheets. The following table presents the receivables and payables from associated companies as of March 31, 2015 and September 30, 2014.



Washington Gas Light Company Receivables / Payables from Associated Companies
(In millions)	March 31, 2015		September 30, 2014
Receivables from Associated Companies	$	3.4	$	4.8
Payables to Associated Companies	$	68.9	$	54.7

Washington Gas provides gas balancing services related to storage, injections, withdrawals and deliveries to all energy marketers participating in the sale of natural gas on an unregulated basis through the customer choice programs that operate in its service territory. These balancing services include the sale of natural gas supply commodities related to various peaking arrangements contractually supplied to Washington Gas and then partially allocated and assigned by Washington Gas to the energy marketers, including WGL Energy Services. Washington Gas records revenues for these balancing services pursuant to tariffs approved by the appropriate regulatory bodies. These related party amounts have been eliminated in the consolidated financial statements of WGL. The following table shows the amounts Washington Gas charged WGL Energy Services for balance services.

(In millions)	2015		2014		2015		2014
Gas balancing service charge	$	9.2	$	14.4	$	14.7	$	18.2

As a result of these balancing services, an imbalance is created for volumes of natural gas received by Washington Gas that are not equal to the volumes of natural gas delivered to customers of the energy marketers. WGL Energy Services recognized an accounts payable to Washington Gas in the amount of $9.5 million and an accounts receivable from Washington Gas in the amount of $0.02 million at March 31, 2015 and September 30, 2014, respectively, related to an imbalance in gas volumes. Due to regulatory treatment, these payables and receivables are not eliminated in the consolidated financial statements of WGL. Refer to Note 1—Accounting Policies of the Notes to Consolidated Financial Statements of the combined Annual Report on Form 10-K for the fiscal year ended September 30, 2014 for further discussion of these imbalance transactions.

Washington Gas participates in a Purchase of Receivables (POR) program as approved by the PSC of MD, whereby it purchases receivables from participating energy marketers at approved discount rates. In addition, WGL Energy Services participates in POR programs with certain Maryland and Pennsylvania utilities, whereby it sells its receivables to various utilities, including Washington Gas, at approved discount rates. The receivables purchased by Washington Gas are included in “Accounts receivable” in the accompanying balance sheet. Any activity between Washington Gas and WGL Energy Services related to the POR program has been eliminated in the accompanying financial statements for WGL. At March 31, 2015 and September 30, 2014, Washington Gas had balances of $38.3 million and $7.7 million, respectively, of purchased receivables from WGL Energy Services.

REGULATORY CONTINGENCIES

Certain legal and administrative proceedings incidental to our business, including regulatory contingencies, involve WGL and/or its subsidiaries. In our opinion, we have recorded an adequate provision for probable losses or refunds to customers for regulatory contingencies related to these proceedings.

NON-UTILITY OPERATIONS

On November 30, 2014, WGL through its subsidiary, WGL Midstream, entered into a gas sale and purchase, and capacity agreement with GAIL Global (USA) LNG LLC, a subsidiary of GAIL (India) Limited, under which WGL Midstream has agreed to sell and deliver a minimum of 340,000 dekatherms per day and up to 430,000 dekatherms per day of natural gas, for a term of 20 years from the in-service date of the export facility. The contract price is based on index pricing, but certain gas sales will occur at a market price per dekatherm of gas based on the estimate of prices prevailing at designated delivery points. WGL Midstream will make deliveries using transportation capacity released by GAIL through an asset management arrangement. On March 10, 2015, WGL Midstream entered into gas purchase commitments to buy 500,000 dekatherms of natural gas per day at index based prices for a 20-year term. We will also be a shipper on the Mountain Valley Pipeline. These commitments were executed in conjunction with the investment in Mountain Valley.

FINANCIAL GUARANTEES

WGL has guaranteed payments primarily for certain purchases of natural gas and electricity on behalf of WGL Energy Services and for certain purchase commitments on behalf of WGL Midstream. At March 31, 2015, these guarantees totaled $239.4 million and $305.9 million for WGL Energy Services and WGL Midstream, respectively. At March 31, 2015, WGL also had guarantees on behalf of other subsidiaries totaling $8.6 million. The amount of such guarantees is periodically adjusted to reflect changes in the level of financial exposure related to these commitments. For all of our financial guarantees, WGL may cancel any or all future obligations upon written notice to the counterparty, but WGL would continue to be responsible for the obligations created under the guarantees prior to the effective date of the cancellation. WGL has also guaranteed payments for certain of our external partners. At March 31, 2015, these guarantees totaled $8.1 million and the fair value of these guarantees was insignificant.

NOTE 16. SUBSEQUENT EVENTS

In the 2014 Session, the General Assembly of the Commonwealth of Virginia amended Title 56 of the Virginia Code. The legislative provisions are intended to encourage regulated utilities to invest in natural gas reserves, upstream pipelines and facilities that are reasonably expected to benefit customers by lowering costs, reducing volatility or lowering the utility’s supply risk. A regulated utility company can obtain the recovery through its rates charged to customers for the entire incurred cost, including the return of and the return on the investment in reserves, as well as all operating costs.

Pursuant to the legislation, on May 6, 2015, WGL entered into a 20-year agreement with Energy Corporation of America (ECA) to acquire natural gas reserves through non-operating working interests in 25 producing wells located in Pennsylvania's Appalachian Basin for $126 million.

The purchase of the reserves is conditional upon approval by the Commonwealth of Virginia's State Corporation Commission (SCC of VA). WGL will submit a filing to the SCC of VA for approval of the investment, with a decision due within 180 days from filing.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

INTRODUCTION

This Management’s Discussion and Analysis of Financial Condition and Results of Operations (Management’s Discussion) analyzes the financial condition, results of operations and cash flows of WGL and its subsidiaries. It also includes management’s analysis of past financial results and potential factors that may affect future results, potential future risks and approaches that may be used to manage them. Except where the content clearly indicates otherwise, “WGL,” “we,” “us” or “our” refers to the holding company or the consolidated entity of WGL Holdings, Inc. and all of its subsidiaries.

Management’s Discussion is divided into the following two major sections:


•	WGL—This section describes the financial condition and results of operations of WGL Holdings, Inc. and its subsidiaries on a consolidated basis. It includes discussions of our regulated operations, including Washington Gas and Hampshire Gas Company (Hampshire), and our non-utility operations.


•	Washington Gas—This section describes the financial condition and results of operations of Washington Gas, a subsidiary of WGL, which comprises the majority of the regulated utility segment.

Both sections of Management’s Discussion—WGL and Washington Gas—are designed to provide an understanding of our operations and financial performance and should be read in conjunction with the respective company’s financial statements and the combined Notes to Consolidated Financial Statements in this quarterly report as well as our combined Annual Report on Form 10-K for WGL and Washington Gas for the fiscal year ended September 30, 2014 (2014 Annual Report).

Unless otherwise noted, earnings per share amounts are presented on a diluted basis, and are based on weighted average common and common equivalent shares outstanding. Our operations are seasonal and, accordingly, our operating results for the interim periods presented are not indicative of the results to be expected for the full fiscal year.

EXECUTIVE OVERVIEW

Introduction

WGL, through its subsidiaries, sells and delivers natural gas and provides a variety of energy-related products and services to customers primarily in the District of Columbia and the surrounding metropolitan areas in Maryland and Virginia. In addition to our primary markets, WGL’s non-utility subsidiaries provide customized energy solutions across a much wider footprint, with business activities in 22 states and the District of Columbia.

WGL has four operating segments:


•	regulated utility;


•	retail energy-marketing;


•	commercial energy systems and


•	midstream energy services.

Regulated Utility Operating Segment

The regulated utility operating segment is composed of our core subsidiary, Washington Gas. Washington Gas engages in the delivery and sale of natural gas that is regulated by regulatory commissions in the District of Columbia, Maryland and Virginia. During the second quarter, our utility customer base continued to grow as average customer meters increased by over 12,800 meters when compared to the same quarter in the prior fiscal year. We saw positive earnings impacts in the segment from the increase in unrealized mark-to-market valuations on our derivatives, as well as from the accelerated pipe replacement plans that are in place in all three of our jurisdictions. Additionally, we filed to amend both our Maryland STRIDE and Virginia SAVE accelerated pipe replacement plans, which will allow us to increase our investment in the utility and see timely earnings recovery on that investment.

Item 2—Management’s Discussion and Analysis of

Financial Condition and Results of Operations (continued)

Retail Energy-Marketing Operating Segment

We offer competitively priced natural gas, electricity and energy from renewable sources to customers through WGL Energy Services, our non-utility retail energy-marketing subsidiary. Our retail energy-marketing business performed well, with electric margins significantly higher than the second quarter of last year. Procedural changes introduced by PJM in response to the market dynamics of last winter have created more stable market conditions during periods of extremely cold weather.

Commercial Energy Systems Operating Segment

Through WGL Energy Systems and WGSW we offer efficient and sustainable commercial energy solutions focused on owning and operating distributed generation assets such as Solar Photovoltaic (Solar PV) systems and upgrading energy related systems of large government and commercial facilities. During the second quarter, this segment experienced higher project expenses in its distributed generation and investment solar divisions. Additionally, the sustained winter weather in the Eastern United States temporarily impacted production of our solar assets. This segment continues to grow its distributed generation assets in service as well as its federal contracting and investment solar businesses.

Midstream Energy Services Operating Segment

WGL Midstream engages in acquiring and optimizing natural gas storage and transportation assets. During the second quarter, this segment experienced lower storage and transportation spreads, as well as a decline in unrealized mark-to-market valuations of derivatives, which were partially offset by lower development expenses. This segment does include, however, initial charges for development expenses pertaining to its investment in the Mountain Valley Pipeline project in the current period. Although extremely cold weather occurred in both the second quarter of fiscal year 2015 and 2014, the volatile commodity prices that created significant optimization opportunities during the second quarter of 2014 did not recur in the second quarter of 2015. Comparative results for the six months ended March 31, 2015, reflect an increase in mark-to-market valuations of our derivatives.

Other Activities

PRIMARY FACTORS AFFECTING WGL AND WASHINGTON GAS

The principal business, economic and other factors that affect our operations and/or financial performance include:


•	weather conditions and weather patterns;


•	regulatory environment, regulatory decisions and changes in legislation;


•	availability of natural gas supply and pipeline transportation and storage capacity;


•	diversity of natural gas supply;


•	volatility of natural gas and electricity prices;


•	non-weather related changes in natural gas consumption patterns;


•	maintaining the safety and reliability of the natural gas distribution system;


•	competitive environment;


•	environmental matters;


•	industry consolidation;


•	economic conditions and interest rates;


•	inflation;


•	use of business process outsourcing; and


•	labor contracts, including labor and benefit costs.

For further discussion of the factors listed above, refer to Management’s Discussion and Analysis of Financial Condition and Results of Operations in the 2014 Annual Report on Form 10-K which was filed with the Securities and Exchange Commission on November 21, 2014. Also, refer to the section entitled “Safe Harbor for Forward-Looking Statements” included in this quarterly report for a listing of forward-looking statements related to factors affecting WGL and Washington Gas.

CRITICAL ACCOUNTING POLICIES

Preparation of financial statements and related disclosures in compliance with Generally Accepted Accounting Principles in the United States of America requires the selection and the application of appropriate technical accounting guidance to the relevant facts and circumstances of our operations, as well as our use of estimates to compile the consolidated financial statements. The application of these accounting policies involves judgment regarding estimates and projected outcomes of future events, including the likelihood of success of particular regulatory initiatives, the likelihood of realizing estimates for legal and environmental contingencies, and the probability of recovering costs and investments in both the regulated utility and non-regulated business segments.

We have identified the following critical accounting policies that require our judgment and estimation, where the resulting estimates may have a material effect on the consolidated financial statements:


•	accounting for unbilled revenue;


•	accounting for regulatory operations — regulatory assets and liabilities;


•	accounting for income taxes;


•	accounting for contingencies;


•	accounting for derivatives;


•	accounting for fair value instruments; and


•	accounting for pension and other post-retirement benefit plans.

For a description of these critical accounting policies, refer to Management’s Discussion within the 2014 Annual Report. There were no new critical accounting policies or changes to our critical accounting policies during the six month period ended March 31, 2015.

RESULTS OF OPERATIONS—Three Months Ended March 31, 2015 vs. March 31, 2014

Beginning in fiscal year 2015, our chief operating decision maker began utilizing earnings before interest and tax (“EBIT”) as the primary measure of profit and loss in assessing the results of each segment’s operations. EBIT includes operating income, other income (expense) and earnings from unconsolidated affiliates. We believe that EBIT enhances the ability to evaluate segment performance because it excludes interest and income tax expense, which are affected by corporate-wide strategies such as capital financing and tax sharing allocations.

EBIT should not be considered as an alternative to, or a more meaningful indicator of our operating performance than, net income. Refer to summary results below for a reconciliation of EBIT to income before income taxes.

⁽¹⁾

We utilize utility net revenues, calculated as revenues less the associated cost of energy and applicable revenue taxes, to assist in the analysis of profitability for the regulated utility segment. The cost of the natural gas commodity and revenue taxes are generally included in the rates that Washington Gas charges to customers as reflected in operating revenues. Accordingly, changes in the cost of gas and revenue taxes associated with sales made to customers generally have no direct effect on utility net revenues, operating income or net income. Utility net revenues should not be considered an alternative, or a more meaningful indicator of our operating performance than operating income. Additionally, utility net revenues may not be comparable to similarly titled measures of other companies.

The increase in EBIT primarily reflects the following:


•	higher utility net revenue related to growth of more than 12,800 average active customer meters;


•	higher unrealized mark-to-market valuations associated with our asset optimization program;


•	favorable effects of changes in natural gas consumption patterns in the District of Columbia and


•	rate recovery related to the accelerated pipeline replacement programs.

Partially offsetting these favorable variances were:

•lower realized margins associated with our asset optimization program;


•	higher operation and maintenance expenses and


•	higher depreciation due to the growth in our utility plant.

Utility Net Revenues. The following table provides the key factors contributing to the changes in the utility net revenues of the regulated utility segment between the three months ended March 31, 2015 and 2014.



Composition of Changes in Utility Net Revenues
(In millions)	Increase/ (Decrease)
Customer growth	$	2.7
Estimated effects of weather and consumption patterns	2.8
Accelerated replacement programs	2.8
Asset optimization:
Realized margins	(4.0		)
Unrealized mark-to-market valuations	49.9
Lower-of-cost or market	0.4
Other	(2.3		)
Total	$	52.3

Customer growth — Average active customer meters increased by more than 12,800 for the three months ended March 31, 2015 compared to the same period of the prior fiscal year.

Estimated effects of weather and consumption patterns — Weather, when measured by HDDs, was 17.3% colder and 16.2% colder than normal for the three months ended March 31, 2015 and 2014, respectively. In the District of Columbia, where Washington Gas does not have a billing mechanism or hedges to offset the effects of weather, the colder weather in the current period resulted in a positive variance to net revenue (refer to the section entitled "Weather Risk" for further discussion of our weather protection strategy). The increase in net revenues also reflects changes in natural gas consumption patterns in the District of Columbia. These changes may be affected by shifts in weather patterns in which customer heating usage may not correlate highly with average historical levels of usage per heating degree days that occur. Natural gas consumption patterns may also be affected by non-weather related factors such as customer conservation.

Accelerated Replacement Programs — Higher revenues are the result of the continued growth of our accelerated pipeline replacement programs in the District of Columbia, Maryland and Virginia (refer to "Rates and Regulatory Matters" for a further discussion of these programs).

Asset optimization — Realized margins for our asset optimization decreased in the current period primarily due to unfavorable transportation spreads when compared to the prior period. We recorded unrealized losses associated with our energy-related derivatives of $28.0 million for the three months ended March 31, 2015, compared to unrealized losses of $77.9 million reported for the same period of the prior fiscal year. When these derivatives settle, any unrealized amounts will ultimately reverse and Washington Gas will realize margins in combination with related transactions that these derivatives economically hedge. The large swings in the valuations are primarily due to movements in unobservable inputs used in the valuation of long-dated forward contracts. We believe that these values are not reflective of our ultimate cash flows as these purchases are utilized in the optimization of our long-term natural gas transportation and storage capacity resources, the value of which is not reflected at fair value. Washington Gas did not record any lower-of-cost or market adjustments related to their storage gas inventory during the three months ended March 31, 2015, and recorded $0.4 million for the three months ended March 31, 2014. Refer to the section entitled “Market Risk—Price Risk Related to the Regulated Utility Segment” for further discussion of our asset optimization program.

Business development	2.5
Operations, engineering, compliance and safety	1.1
Prior year insurance proceeds	1.7
Support services	1.6
Other	0.2
Total	$	9.1

Employee incentives and direct labor costs — Washington Gas incurred increased employee incentives and labor costs for the three months ended March 31, 2015 over the same period of the previous fiscal year, as a result of merit increases as well as an increase in the valuation of our share-based long-term incentive plan.

Business development — The increase primarily relates to an increase in business development costs incurred by Washington Gas.

Employee benefits — The decrease primarily relates to an amendment to the post-retirement benefits plan resulting in a re-measurement of the benefit obligation and a reduction in the net periodic expense for the quarter compared to the same period of the prior year.

Operations, engineering, compliance and safety — Washington Gas incurred increased maintenance costs for the three months ended March 31, 2015 compared to the same period of the previous fiscal year primarily due to safety and reliability activities related to the cold weather.

Prior year insurance proceeds — The increase in operations and maintenance expense for the three months ended March 31, 2015 over the same period of the prior fiscal year reflects proceeds from Washington Gas' insurance policies for incurred legal costs and past and future environmental expenses that were received in same period of the prior fiscal year.

Support services — Washington Gas incurred additional costs for the three months ended March 31, 2015 compared to the same period of the prior fiscal year due to increased project related costs including the implementation of a new customer information system as well as infrastructure support costs.

Depreciation and Amortization. The $1.7 million increase in depreciation and amortization reflects growth in our investment in utility plant.

⁽¹⁾

We utilize gross margins to assist with the analysis of profitability for the retail energy-marketing segment. Gross margins are calculated as revenues less the associated cost of energy and applicable revenue taxes. We consider gross margins to be a better reflection of profitability than gross revenues or gross energy costs for our retail energy-marketing segment because gross margins are a direct measure of the success of our core strategy for the sale of natural gas and electricity. Gross margins should not be considered an alternative, or a more meaningful indicator of our operating performance than operating income. Additionally, gross margins may not be comparable to similarly titled measures of other companies.

The increase in EBIT primarily reflects higher realized margins for electricity in the current period. Period-to-period comparisons of quarterly gross margins for this segment can vary significantly and are not necessarily representative of expected annualized results.

The comparison of gross margins from natural gas sales, between the three months ended March 31, 2015 and 2014, reflects higher unrealized mark-to-market valuations due to fluctuating market prices and a decrease in realized natural gas margins due to lower weather hedge benefits, partially offset by higher margins from wholesale and retail portfolio optimization activity.

The increase in gross margins from electric sales, between the three months ended March 31, 2015 and 2014, reflects significantly improved realized electric retail margins due to lower supply costs and lower capacity and ancillary service charges from the regional power grid operator (PJM) associated with fixed price retail contracts. Prior year electricity margins reflected extreme price movements on commodity prices as the result of colder than normal weather that occurred

EBIT	$	(23.5	)	$	21.6	$	(45.1	)


^(a)	The trading margins of Midstream Energy Services, including unrealized gains and losses on derivative instruments, are netted within operating revenues.

The decrease in EBIT reflects lower mark-to-market valuations on our derivative instruments of $40.6 million and a $3.0 million reduction to net income due to a lower-of-cost or market adjustment on storage gas inventory in the current period. Additionally, realized margins decreased due to unfavorable transportation and storage spreads. These unfavorable variances were partially offset by lower development expenses related to our pipeline investments. The current period includes a $2.6 initial charge for development expenses pertaining to the Mountain Valley Pipeline project. The prior period included approximately $4.3 million related to our investment in Meade.

Other Non-Utility Activities

Transactions that are not significant enough on a stand-alone basis to warrant treatment as an operating segment, and that do not fit into one of our four operating segments, are aggregated as “Other Activities” and included as part of non-utility operations. Our other non-utility activities reflect EBIT of $(0.8) million and $(5.1) million for the three months ended March 31, 2015 and 2014, respectively. The comparison reflects lower holding company branding initiative and business development costs in the current period.

Intersegment Eliminations

Intersegment eliminations represent timing differences between Commercial Energy Systems’ recognition of revenue for the sale of SREC’s to Retail Energy-Marketing and Retail Energy-Marketing’s recognition of the associated expense.

⁽¹⁾We utilize utility net revenues, calculated as revenues less the associated cost of energy and applicable revenue taxes, to assist in the analysis of profitability for the regulated utility segment. The cost of the natural gas commodity and revenue taxes are generally included in the rates that Washington Gas charges to customers as reflected in operating revenues. Accordingly, changes in the cost of gas and revenue taxes associated with sales made to customers generally have no direct effect on utility net revenues, operating income or net income. Utility net revenues should not be considered an alternative, or a more meaningful indicator of our operating performance than operating income. Additionally, utility net revenues may not be comparable to similarly titled measures of other companies.

The increase in EBIT primarily reflects the following:


•	higher utility net revenue related to the growth of more than 12,400 average active customer meters;


•	favorable effects of changes in natural gas consumption patterns in the District of Columbia;


•	higher unrealized mark-to-market valuations associated with our asset optimization program;


•	rate recovery related to the accelerated pipeline replacement programs and


•	higher revenues due to new base rates in Maryland.

Partially offsetting these favorable variances were:


•	lower realized margins associated with our asset optimization program;


•	higher operation and maintenance expenses and


•	higher depreciation due to the growth in our utility plant.

Total	$	105.5

Customer growth — Average active customer meters increased by more than 12,400 for the six months ended March 31, 2015 compared to the same period of the prior fiscal year.

Estimated effects of weather and consumption patterns — This variance in net revenues primarily reflects the changes in natural gas consumption patterns in the District of Columbia. These changes may be affected by shifts in weather patterns in which customer heating usage may not correlate highly with average historical levels of usage per heating degree days that occur. Natural gas consumption patterns may also be affected by non-weather related factors such as customer conservation. Additionally, weather, when measured by HDDs, was 8.0% colder and 11.4% colder than normal for the six months ended March 31, 2015 and 2014, respectively.

Impact of rate cases — New base rates were approved in Maryland effective November 23, 2013.

Accelerated replacement programs — Higher revenues are the result of the continued growth of our accelerated pipeline replacement programs in the District of Columbia, Maryland and Virginia.

Asset optimization — Realized margins for our asset optimization decreased in the current period primarily due to unfavorable transportation spreads when compared to the prior period. We recorded unrealized losses associated with our energy-related derivatives of $2.9 million for the six months ended March 31, 2015 compared to net unrealized losses of $104.1 million for the same period of the prior fiscal year. When these derivatives settle, any unrealized amounts will ultimately be reversed, and Washington Gas will realize margins in combination with the related transactions that these derivatives economically hedge. Unfavorably affecting asset optimization results were $0.7 million and $0.4 million of lower-of-cost or market adjustments related to storage gas inventory during the six months ended March 31, 2015 and 2014, respectively. (Refer to the section entitled “Market Risk-Price Risk Related to the Regulated Utility Segment” for a further discussion of our asset optimization program).

Employee benefits — The decrease relates to an amendment to the post-retirement benefits plan resulting in a re-measurement of the benefit obligation and a reduction in the net periodic expense for the current period compared to the same period of the prior year.

Business development — The increase primarily relates to an increase in business development costs incurred by Washington Gas.

Operations, engineering, compliance and safety — Washington Gas incurred increased maintenance costs for the six months ended March 31, 2015 than for the same period of the previous fiscal year due primarily to safety and reliability activities related to the cold weather.

Prior year insurance proceeds — The increase in operations and maintenance expense during the six month period ended March 31, 2015 over the same period of the prior fiscal year reflects the proceeds from Washington Gas' insurance policies for incurred legal costs and past and future environmental expenses, received in the same period of the prior fiscal year .

Support services — Washington Gas incurred additional costs for the six months ended March 31, 2015 compared to the same period of the prior fiscal year due to increased project related costs including the implementation of a new customer information system as well as infrastructure support costs.

We consider gross margins to be a better reflection of profitability than gross revenues or gross energy costs for our retail energy-marketing segment because gross margins are a direct measure of the success of our core strategy for the sale of natural gas and electricity. Gross margins should not be considered an alternative, or a more meaningful indicator of our operating performance than operating income. Additionally, gross margins may not be comparable to similarly titled measures of other companies.

The increase in EBIT primarily reflects improved realized margins for electricity in the current period. Period-to-period comparisons of gross margins for this segment can vary significantly and are not necessarily representative of expected annualized results.

The comparison of gross margins from natural gas sales, between the six months ended March 31, 2015 and 2014, reflects lower unrealized mark-to-market valuations due to fluctuating market prices and lower realized natural gas margins due to lower weather hedge benefits and lower customer counts due to competition, partially offset by higher wholesale and retail portfolio optimization activity.

The comparison of gross margins from electric sales, between the six months ended March 31, 2015 and 2014, reflects significantly improved realized electric retail margins due to lower supply, capacity and ancillary service charges from the regional power grid operator (PJM) associated with fixed price retail contracts, partially offset by lower unrealized mark-

to-market valuations due to fluctuating market prices. Prior year electricity margins reflected extreme price movements on commodity prices as the result of colder than normal weather that occurred throughout January 2014. These improvements were slightly offset by lower sales volumes due to lower customer counts and lower margins on large commercial sales due to competition.

Commercial Energy Systems

The table below represents the financial results by division of the commercial energy systems segment for the six months ended March 31, 2015 and 2014.

EBIT	$	3.3	$	(12.6	)	$	15.9


^(a)	The trading margins of Midstream Energy Services, including unrealized gains and losses on derivative instruments, are netted within operating revenues.

The improvement to EBIT primarily reflects higher mark-to-market valuations on our derivative instruments of $36.1 million as well as lower investment development expenses related to our pipeline investments. These favorable variances were partially offset by a $20.5 million reduction to income due to a lower-of-cost or market adjustment on storage gas inventory and unfavorable storage and transportation spreads which affected our realized margins.

Other Non-Utility Activities

Transactions that are not significant enough on a stand-alone basis to warrant treatment as an operating segment, and that do not fit into one of our four operating segments, are aggregated as “Other Activities” and included as part of non-utility operations. Our other non-utility activities reflect EBIT of $(7.9) million and $(7.8) million for the six months ended March 31, 2015 and 2014, respectively. The comparison reflects a $5.6 million impairment related to ASDHI recorded in the current six month period and higher holding company branding initiative and business development costs in the prior period.

Intersegment Eliminations

Intersegment eliminations represent timing differences between Commercial Energy Systems' recognition of revenue for the sale of SREC's to Retail Energy-Marketing and Retail Energy-Marketing's recognition of the associated expense.

Consolidated Interest Expense

The following table shows the components of WGL’s consolidated interest expense for the six months ended March 31, 2015 and 2014. The increase in interest on long-term debt primarily comprises new unsecured MTNs and private placement notes issued by Washington Gas and senior notes issued by WGL.

Consolidated Income Taxes

The following table shows WGL’s consolidated income tax expense and effective income tax rate for the six months ended March 31, 2015 and 2014.



Consolidated Income Taxes
	Six Months Ended March 31,						Increase/

Income tax expense	92.1			40.0			52.1
Effective income tax rate	38.7		%	33.2		%	5.5		%

The increase in the effective income tax rate, when comparing the six months ended March 31, 2015 and 2014, is a result of the tax benefit recorded during the first quarter of fiscal year 2014 for the reinstatement of regulatory assets related to the tax effect of Med D, causing the rate to be lower during the prior year period. Refer to Note 9—Income Taxes of the Notes to the Consolidated Financial Statements of our combined Annual Report on Form 10-K for details.

LIQUIDITY AND CAPITAL RESOURCES

General Factors Affecting Liquidity

Access to short-term debt markets is necessary for funding our short-term liquidity requirements, the most significant of which include buying natural gas, electricity, and pipeline capacity, in addition to financing accounts receivable and storage gas inventory. Our need for access to long-term capital markets is driven primarily by capital expenditures, investment opportunities, maturities of long-term debt, and the availability of government funding through deferred taxes.

During the six months ended March 31, 2015, both WGL and Washington Gas met their liquidity and capital needs through retained earnings, the issuance of commercial paper and long-term debt.

Our ability to access capital markets depends on our credit ratings, general market liquidity, and investor demand for our securities. Our credit ratings depend largely on the financial performance of our subsidiaries, and a ratings downgrade could both increase our borrowing costs and trigger the need for posting additional collateral with our wholesale counterparties or other creditors. In support of our credit ratings, we have a goal to maintain our common equity ratio in the 50% range of total consolidated capital. As of March 31, 2015, total consolidated capitalization, including current maturities of long-term debt and excluding notes payable, comprised 57.1% common equity, 1.2% preferred stock and 41.7% long-term debt. The level of this ratio varies during the fiscal year due to the seasonal nature of our business. This seasonality also affects our short-term debt balances, which are typically higher in the fall and winter months and substantially lower in the spring when a significant portion of our current assets are converted into cash at the end of the heating season. Our cash flow requirements and our ability to provide satisfactory resources to meet those requirements are primarily influenced by the activities of all of WGL’s operating segments.

Our plans provide for sufficient liquidity to satisfy our financial obligations. At March 31, 2015, we had no restrictions on our cash balances or retained earnings that would affect the payment of common or preferred stock dividends by either WGL or Washington Gas.

Short-Term Cash Requirements and Related Financing

Washington Gas has seasonal short-term cash requirements to fund the purchase of storage gas inventory in advance of the winter heating season. At March 31, 2015 and September 30, 2014, Washington Gas had balances in gas storage of $41.3 million and $156.1 million, respectively. Washington Gas collects the cost of gas under cost recovery mechanisms approved by its regulators. Additionally, Washington Gas may be required to post cash collateral for certain purchases.

During the first six months of our fiscal year, Washington Gas’ large sales volumes cause its cash requirements to peak when combined storage inventory, accounts receivable, and unbilled revenues are at their highest levels. During the last six months of our fiscal year, after the heating season, Washington Gas will typically experience a seasonal net loss due to reduced demand for natural gas. During this period, large amounts of Washington Gas’ current assets are converted to cash, which Washington Gas generally uses to reduce and sometimes eliminate short-term debt and acquire storage gas for the next heating season.

Variations in the timing of collections under its gas cost recovery mechanisms can significantly affect Washington Gas’ short-term cash requirements. At March 31, 2015 and September 30, 2014, Washington Gas had $0.4 million in net under-

Washington Gas Light Company

Part I—Financial Information

Item 2—Management’s Discussion and Analysis of

Financial Condition and Results of Operations (continued)

collections and $9.8 million in net over-collections, respectively, of gas costs reflected in current liabilities as gas costs due to customers. Amounts under-collected or over-collected that are generated during the current gas cost recovery cycle are deferred as a regulatory asset or liability on the balance sheet until September 1 of each year, at which time the accumulated amount is transferred to gas costs due from/to customers as appropriate. At March 31, 2015 and September 30, 2014, Washington Gas had net regulatory assets of $34.5 million and $0.9 million, respectively, related to the current gas recovery cycle.

WGL and Washington Gas use short-term debt in the form of commercial paper or unsecured short-term bank loans to fund seasonal cash requirements. Our policy is to maintain back-up bank credit facilities in an amount equal to or greater than our expected maximum commercial paper position. Bank credit balances available to WGL and Washington Gas, net of commercial paper balances, were $275.0 million and $350.0 million at March 31, 2015, and $85.5 million and $261.0 million at September 30, 2014, respectively.

On December 19, 2014, WGL and Washington Gas each entered into a first amendment to its respective credit agreements, each dated April 3, 2012. The amendments extend the maturity date of each credit facility until December 19, 2019, provided that the credit facilities will terminate on September 30, 2017 if Washington Gas does not obtain an extension of a regulatory approval authorizing the incurrence of short-term indebtedness. The credit facility for WGL permits it to borrow up to $450.0 million, and further permits, with the banks’ approval, additional borrowings of $100.0 million for a maximum potential total of $550.0 million. The credit facility for Washington Gas permits it to borrow up to $350.0 million, and further permits, with the banks’ approval, additional borrowings of $100.0 million for a maximum potential total of $450.0 million. The interest rate on loans made under each of the credit facilities will be a fluctuating rate per annum that will be set using certain parameters at the time each loan is made. WGL and Washington Gas incur credit facility fees, which in some cases are based on the long-term debt ratings of Washington Gas. In the event that the long-term debt of Washington Gas is downgraded below certain levels, WGL and Washington Gas would be required to pay higher fees. There are five different levels of fees. The credit facility for WGL defines its applicable fee level as one level below the level applicable to Washington Gas. Under the terms of the credit facilities, the lowest level facility fee is 0.06% and the highest is 0.175%. The credit agreements as amended each have the right to request two additional one-year extensions, with the banks’ approval. Refer to Note 3—Short-Term Debt of the Notes to the Consolidated Financial Statements for further information.

A share repurchase program was approved by the Board of Directors and announced on August 7, 2014 to repurchase WGL’s common stock up to an amount of $150 million. The shares may be repurchased in the open market or in privately negotiated transactions. The repurchase program is authorized for a two year period. During the six months ended March 31, 2015, we repurchased 1.0 million shares of common stock for a cost of $41.5 million. Since the program’s inception, we have repurchased 2.3 million shares of common stock for a total cost of $97.6 million.

To manage credit risk, Washington Gas may require certain customers and suppliers to provide deposits, which may include collateral from wholesale counterparties, which are reported as current liabilities in “Customer deposits and advance payments,” in the accompanying balance sheets. At March 31, 2015 and September 30, 2014, “Customer deposits and advance payments” totaled $82.5 million and $68.3 million, respectively. For Washington Gas, deposits from customers may be refunded at various times throughout the year based on the customer’s payment habits. At the same time, other customers make new deposits that cause the balance of customer deposits to remain relatively steady. There are no restrictions on Washington Gas’ use of these customer deposits. Washington Gas pays interest to its customers on these deposits in accordance with the requirements of its regulatory commissions.

For WGL Energy Services and WGL Midstream, deposits would typically represent collateral for transactions with wholesale counterparties. These deposits may be reduced, repaid or increased at any time based on the current value of WGL Energy Services’ or WGL Midstream’s net position with the counterparty. Currently, there are no restrictions on the use of deposited funds and interest is paid to the counterparty on these deposits in accordance with its contractual obligations. Refer to the section entitled "Credit Risk" for further discussion of our management of credit risk.

WGL Energy Services and WGL Midstream have seasonal short-term cash requirements to fund the purchase of storage gas inventory in advance of the winter heating season. At March 31, 2015 and September 30, 2014, WGL Energy Services had balances in gas storage of $5.1 million and $50.5 million, respectively. WGL Energy Services collects revenues that are designed to reimburse commodity costs used to supply their retail customer and wholesale counterparty contracts. At March 31, 2015 and September 30, 2014, WGL Midstream had balances in gas storage of $49.8 million and $127.0 million, respectively. As market opportunities arise, WGL Midstream collects revenues in excess of its commodity costs through its wholesale counterparty contracts. WGL Energy Services and WGL Midstream derive funding to finance these activities from short-term debt issued by WGL. Additionally, WGL Energy Services and WGL Midstream may be required to post cash collateral for

certain purchases. WGL Energy Services and WGL Midstream may be required to provide parent guarantees from WGL for certain transactions.

In addition to storage gas, WGL Midstream also has cash requirements to fund the capital requirements of its various pipeline investments. At March 31, 2015, WGL Midstream had a $49.5 million investment related to these pipelines. WGL Midstream derives funding to finance these activities from short-term debt issued by WGL.

WGL Energy Systems has cash requirements to fund the construction and purchase of residential and commercial distributed generating systems. WGL Energy Systems derives funding to finance these activities from short-term and long-term debt issued by WGL but may also utilize long-term debt issued by WGL.

Long-Term Cash Requirements and Related Financing

The primary drivers of our long-term cash requirements include capital expenditures, non-utility investments, long-term debt maturities, decisions to refinance long-term debt and our share repurchase program. For the regulated utility segment, our capital expenditures primarily relate to adding new utility customers and system supply as well as maintaining the safety and reliability of Washington Gas’ distribution system. Refer to the section entitled “Capital Investments” for discussion of our capital expenditures forecast and our 2014 Annual Report for a discussion of our long-term debt maturities.

For our non-utility segments, our long-term cash requirements primarily depend upon the level of investments and capital expenditures. For WGL Midstream, our investments primarily relate to providing capital for construction of the pipeline investments. For WGL Energy Systems, our investments primarily relate to providing capital for construction of new residential and commercial solar projects.

WGL Debt Issuances. On October 24, 2014, WGL issued $100.0 million of 2.25% notes due November 1, 2019 (“2019 Notes”) and $125.0 million of 4.60% notes due November 1, 2044 (“2044 Notes”). The notes were priced at 99.79% and 99.23% of par, respectively. WGL may redeem the 2019 Notes at any time prior to October 1, 2019 subject to a make whole premium plus accrued and unpaid interest. At any time on or after October 1, 2019, WGL may redeem the 2019 Notes at any time at 100% of the principal of such notes, plus accrued and unpaid interest. WGL may redeem the 2044 Notes at any time prior to May 1, 2044 subject to a make whole premium, plus accrued and unpaid interest. WGL may redeem the 2044 Notes at any time on or after May 1, 2044 at 100% of the principal of such notes, plus accrued and unpaid interest.

On December 16, 2014, WGL re-opened the 2044 Notes offering and sold an additional $25.0 million of 4.60% notes due November 1, 2044. These additional notes were priced at 97.61% of par. In order to match interest payments with the earlier issuance, WGL received $0.2 million of accrued interest at the settlement date. These notes have the same terms and provisions as the earlier issuance.

In March 2015, WGL entered into intercompany agreements with three of its affiliates, WGL Energy Systems, WGSW and WGL Midstream. These agreements have terms consistent with WGL’s 2019 and 2044 notes issued in October and December 2014. The intercompany loans are eliminated in consolidation.

The net proceeds from the sale of these notes have been used by WGL primarily to fund the repurchase of outstanding securities of WGL and capital investments of its non-utility subsidiaries.

Washington Gas Debt Issuances. On December 15, 2014, Washington Gas issued $50.0 million of 4.24% notes due December 15, 2044 in a private placement exempt from the registration requirements of the Securities Act of 1933 in reliance on Section 4(a)(2) of the Securities Act. Proceeds from these notes, after the payment of placement fees in connection with the transaction, have been used for general corporate purposes.

Security Ratings

The table below reflects the current credit ratings for the outstanding debt instruments of WGL and Washington Gas. Changes in credit ratings may affect WGL’s and Washington Gas’ cost of short-term and long-term debt and our access to the capital markets. A security rating is not a recommendation to buy, sell or hold securities. The rating may be subject to revision or withdrawal at any time by the assigning rating organization and each rating should be evaluated independently of any other rating.

(a) The long-term debt ratings outlook issued by Fitch Ratings for WGL and Washington Gas is stable.

(b) The long-term debt ratings outlook issued by Moody’s Investors Service for WGL and Washington Gas is stable.

Ratings Triggers and Certain Debt Covenants

WGL and Washington Gas pay credit facility fees, which in some cases are based on the long-term debt ratings of Washington Gas. Under the terms of WGL’s and Washington Gas' credit agreements and debt issuances, the ratio of consolidated financial indebtedness to consolidated total capitalization cannot exceed 0.65 to 1.0 (65.0%). In addition, WGL and Washington Gas are required to inform lenders of changes in corporate existence, financial conditions, litigation and environmental warranties that might have a material effect on debt ratings. The failure to inform the lenders’ agent of material changes in these areas might constitute default under the agreements. Additionally, failure to pay principal or interest on any other indebtedness may be deemed a default under our credit agreements. A default, if not remedied, may lead to a suspension of further loans and/or acceleration in which obligations become immediately due and payable. At March 31, 2015, we were in compliance with all of the covenants under our revolving credit facilities.

For certain of Washington Gas’ natural gas purchase and pipeline capacity agreements, if the long-term debt of Washington Gas is downgraded to or below the lower of a BBB- rating by Standard & Poor’s or a Baa3 rating by Moody’s Investors Service, or if Washington Gas is deemed by a counterparty not to be creditworthy, then the counterparty may withhold service or deliveries, or may require additional credit support. For certain other agreements, if the counterparty’s credit exposure to Washington Gas exceeds a contractually defined threshold amount, or if Washington Gas’ credit rating declines by a certain rating level, then the counterparty may require additional credit support. At March 31, 2015, Washington Gas would not be required to provide additional credit support by these arrangements if its long-term credit rating was to be downgraded by one rating level.

WGL guarantees payments for certain purchases of natural gas and electricity on behalf of WGL Energy Services and WGL Midstream (refer to “Contractual Obligations, Off-Balance Sheet Arrangements and Other Commercial Commitments” for a further discussion of these guarantees). If the credit rating of WGL declines, WGL Energy Services and WGL Midstream may be required to provide additional credit support for these purchase contracts. At March 31, 2015, WGL Energy Services would be required to provide minimal additional credit support for these arrangements if the long-term credit rating of WGL was to be downgraded by one rating level. At March 31, 2015, WGL Midstream would not be required to provide additional credit support for these arrangements if the long-term credit rating of WGL was to be downgraded by one rating level.

Historical Cash Flows

The following table summarizes WGL’s net cash provided by (used in) operating, investing and financing activities for the six months ended March 31, 2015 and 2014:



	Six Months Ended March 31,
(In millions)	2015			2014			Increase/ (Decrease)

Financing activities	$	(70.9	)	$	(65.8	)	$	(5.1	)

Cash Flows Provided by Operating Activities

The regulated utility’s cash flows from operating activities principally reflect gas sales and deliveries and the cost of operations. The volume of gas sales and deliveries is dependent primarily on factors external to the utility, such as growth of customer demand, weather, market prices for energy, economic conditions and measures that promote energy efficiency. Under revenue and weather normalization, ratemaking adjustments and decoupling mechanisms in place, changes in delivery volumes from levels assumed when rates were approved may affect the timing of cash flows but not net income. The price at which the utility provides energy to customers is determined in accordance with regulatory approved tariffs. In general, changes in the utility’s cost gas may affect the timing of cash flows but not net income because the costs are recovered in accordance with rate agreements. In addition, the regulated utility’s cash flow is impacted by the timing of derivative settlements.

The non-utility cash flows from operating activities primarily reflect the timing of receipts related to distributed generation and federal projects at commercial energy systems and the timing of receipts related to electric and gas bills for WGL Energy services. The timing of gas purchases and sales resulting from asset optimization arrangements affect WGL Midstream. Both WGL Energy Services and WGL Midstream cash flows are impacted by the timing of derivative settlements.

Net income is the result of cash and non-cash (or accrual) transactions. Only cash transactions affect WGL’s cash flows from operating activities. Principal non-cash charges include depreciation, accrued or deferred pension and other post-retirement benefit costs and deferred income tax expense. Non-cash charges or credits may also be accrued under the revenue decoupling and cost reconciliation mechanisms in the utilities’ rate plans.

Net cash flows provided by operating activities for the six months ended March 31, 2015 was $305.8 million compared to $242.1 million for the six months ended March 31, 2014. The increase in net cash flows reflects timing differences with respect to cash flows for energy related payments and receipts as well as the timing of income tax payments.

The change in regulatory assets principally reflects changes in deferred pension and post-retirement benefit costs in accordance with the accounting rules for retirement benefits.

Cash Flows Used in Investing Activities

During the six months ended March 31, 2015, cash flows used in investing activities totaled $(234.4) million compared to $(167.8) million for the six months ended March 31, 2014. Capital expenditures increased by $(66.8) million due to additional funding for WGL's accelerated pipeline replacement programs, as well as investments in commercial solar and pipeline projects for our non-utility subsidiaries.

Cash Flows Used in Financing Activities

Cash flows used in financing activities totaled $(70.9) million for the six months ended March 31, 2015, a $(5.1) million increase over the same period of the prior year. This increase reflects $(41.5) million in common stock repurchased during the first quarter of fiscal year 2015 and a $(219.9) million net change in notes notes payable issued (retired), partially offset by the $258.2 million increase in the net issuance of long-term debt.

Constitution Pipeline

In May 2013, WGL Midstream entered into an equity investment in Constitution Pipeline Company, LLC. The pipeline project is designed to transport at least 650,000 dekatherms of natural gas per day from the Marcellus region in northern Pennsylvania to major northeastern markets. Fully contracted with long-term commitments from established natural gas producers currently operating in Pennsylvania, the pipeline will originate from the Marcellus production areas in Susquehanna County, PA, and interconnect with the Iroquois Gas Transmission and Tennessee Gas Pipeline systems in Schoharie County, N.Y.

Constitution Pipeline LLC has adjusted the pipeline’s targeted in-service date to the second half of 2016 as a result of a longer than expected regulatory and permitting process. An affiliate of Williams Partners will construct, operate and maintain the new 30-inch, 126-mile long transmission pipeline.

WGL Midstream will invest an estimated $79.0 million in the project for a 10% share in the pipeline venture. WGL Midstream joins Williams Partners L.P. (41% share), Cabot Oil and Gas Corporation (25% share) and Piedmont Natural Gas (24% share) in the project. In June 2013, Constitution Pipeline filed a formal certificate application with FERC. On December 2, 2014, the FERC issued an order granting a Certificate of Public Convenience and Necessity.

Central Penn Line Pipeline

In February 2014, WGL Midstream entered into a limited liability company agreement and formed Meade, with COG Holdings LLC, Vega Midstream MPC LLC, and River Road Interests LLC.

Meade was formed to jointly develop and own, together with Transcontinental Gas Pipe Line Company, LLC (Transco), an approximately 177-mile pipeline originating in Susquehanna County, Pennsylvania and extending to Lancaster County, Pennsylvania (Central Penn) that will have the capacity to transport and deliver up to approximately 1.7 million dekatherms per day of natural gas. This pipeline will be an integral part of Transco’s “Atlantic Sunrise” project.

Central Penn, as part of Atlantic Sunrise, is a natural gas pipeline designed to provide new firm transportation capacity from various supply points in northeast Pennsylvania to a delivery point into Transco’s mainline in southeast Pennsylvania. Central Penn currently has a projected in-service date in the second half of 2017. WGL Midstream will invest an estimated $410.0 million for a 55% interest in Meade, and Meade will invest an estimated $746 million in Central Penn for an approximate 39% interest in Central Penn. Transco will have the remaining ownership interests.

Additionally, in February 2014, WGL Midstream entered into an agreement with Cabot Oil & Gas Corporation (Cabot) whereby WGL Midstream will purchase 500,000 dekatherms per day of natural gas from Cabot over a 15 year term. As part of this agreement, Cabot will acquire 500,000 dekatherms per day of firm gas transportation capacity on Transco’s Atlantic Sunrise project of which Central Penn is a part. This capacity will be released to WGL Midstream.

Mountain Valley Pipeline

In March 2015, WGL Midstream acquired a 7% equity interest in Mountain Valley.

The proposed pipeline to be developed, constructed, owned and operated by Mountain Valley will transport approximately 2.0 million dekatherms of natural gas per day from a new interconnect with EQT Corporation's Equitrans system, near the MarkWest Mobley plant in Smithfield, West Virginia to Transco's Station 165 in Pittsylvania County, Virginia. The pipeline is scheduled to be in service by December 2018.

The total project investment is anticipated to be between $3.0-$3.5 billion. WGL Midstream will invest, in scheduled capital contributions through the in-service date of the pipeline, its pro rata share (based on its 7% equity interest) of project costs, which is estimated to be $230 million. In addition, WGL Midstream entered into a gas purchase commitment to buy 500,000 dekatherms of natural gas per day, at index-based prices, for a 20 year term. We will also be a shipper on the proposed pipeline.

CREDIT RISK

Wholesale Credit Risk

Certain wholesale suppliers that sell natural gas to any or all of Washington Gas, WGL Energy Services, and WGL Midstream may have relatively low credit ratings or may not be rated by major credit rating agencies.

Washington Gas enters into transactions with wholesale counterparties for the purpose of meeting firm ratepayer commitments, to optimize the value of its long-term capacity assets, and for hedging natural gas costs. In the event of a counterparty’s failure to deliver contracted volumes of gas or fulfill its payment obligations, Washington Gas may incur losses

WGL Holdings, Inc.

Washington Gas Light Company

Part I—Financial Information

Item 2—Management’s Discussion and Analysis of

Financial Condition and Results of Operations (continued)

that would typically be passed through to its sales customers under the purchased gas cost adjustment mechanisms. Washington Gas may be at risk for financial loss to the extent these losses are not passed through to its customers.

For WGL Energy Services, any failure of wholesale counterparties to deliver natural gas or electricity under existing contracts could cause financial exposure for the difference between the price at which WGL Energy Services has contracted to buy these commodities and their replacement cost from another supplier. To the extent that WGL Energy Services sells natural gas to these wholesale counterparties, WGL Energy Services may be exposed to payment risk if WGL Energy Services is in a net receivable position. Additionally, WGL Energy Services enters into contracts with counterparties to hedge the costs of natural gas and electricity. Depending on the ability of the counterparties to fulfill their commitments, WGL Energy Services could be at risk for financial loss.

WGL Midstream enters into transactions with wholesale counterparties to hedge and optimize its portfolio of owned and managed natural gas assets. Any failure of wholesale counterparties to deliver natural gas under existing contracts could cause financial exposure for the difference between the price at which WGL Midstream has contracted to buy these commodities and their replacement cost. To the extent that WGL Midstream sells natural gas to these wholesale counterparties, WGL Midstream may be exposed to payment risk if it is in a net receivable position. In addition, WGL Midstream enters into contracts with counterparties to hedge the costs of natural gas. Depending on the ability of the counterparties to fulfill their commitments, WGL Midstream could be at risk for financial loss.

Washington Gas, WGL Energy Services, and WGL Midstream operate under an existing wholesale counterparty credit policy that is designed to mitigate credit risks through requirements for credit enhancements including, but not limited to, letters of credit, parent guarantees and cash collateral when deemed necessary. In accordance with this policy, Washington Gas, WGL Energy Services, and WGL Midstream have each obtained credit enhancements from certain of their counterparties. If certain counterparties or their guarantors meet the policy’s creditworthiness criteria, Washington Gas, WGL Energy Services, and WGL Midstream may grant unsecured credit to those counterparties or their guarantors. The creditworthiness of all counterparties is continuously monitored.

Washington Gas, WGL Energy Services and WGL Midstream are also subject to the collateral requirements of their counterparties. At March 31, 2015, Washington Gas, WGL Energy Services and WGL Midstream provided $3.0 million, $25.7 million and $8.6 million in cash collateral to counterparties, respectively.

^(a)

Investment Grade is primarily determined using publicly available credit ratings of the counter-party. If the counter party has provided a guarantee by a higher-rated entity (e.g., its parent), it is determined based upon the rating of it guarantor. Included in “Investment Grade” are counterparties with a minimum Standard & Poor’s or Moody’s Investor Service rating of BBB- or Baa3, respectively.


^(b)	Includes the net of all open positions on energy-related derivatives subject to mark-to-market accounting requirements and the net receivable/payable for the realized transactions.

^(c)	Represents cash deposits and letters of credit received from counterparties, not adjusted for probability of default.


^(d)	Using a percentage of the net exposure.

Retail Credit Risk

Washington Gas is exposed to the risk of non-payment of utility bills by certain of its customers. To manage this customer credit risk, Washington Gas may require cash deposits from its high risk customers to cover payment of their bills until the requirements for the deposit refunds are met. In addition, Washington Gas implemented a POR program as approved by the PSC of MD, whereby it purchases receivables from participating energy marketers at approved discount rates. Under the program, Washington Gas is exposed to the risk of non-payment by the retail customers for these receivables. This risk is factored into the approved discount rate at which Washington Gas purchases the receivables.

WGL Energy Services is also exposed to the risk of non-payment by its retail customers. WGL Energy Services manages this risk by evaluating the credit quality of certain new customers as well as by monitoring collections from existing customers. To the extent necessary, WGL Energy Services can obtain collateral from, or terminate service to, its existing customers based on credit quality criteria. In addition, WGL Energy Services participates in POR programs with certain Maryland, District of Columbia and Pennsylvania utilities, whereby it sells its receivables to various utilities at approved discount rates. Under the POR programs, WGL Energy Services is exposed to the risk of non-payment by its retail customers for delivered commodities that have not yet been billed. Once the invoices are billed, however, the associated credit risk is assumed by the purchasing utilities that sponsor POR programs. While participation in POR programs reduce the risk of collection and fixes a discount rate on the receivables, there is a risk that the discount rate paid to participate in the POR program will exceed the actual bad debt expense and billing fees associated with these receivables.

WGL Energy Systems is subject to retail credit risk associated with customers who purchase electricity under long term agreements from distributed generation assets owned by the company. The customers undergo credit evaluation prior to contract execution and are monitored periodically during the contract term for payment performance and credit quality. These steps mitigate credit risk associated with the distributed generation asset customers.

WGSW is indirectly subject to retail credit risk associated with non-payment by customers who lease distributed energy equipment or maintain energy service agreements through ASD Solar LP, Nextility and SunEdison. This credit risk is mitigated

with minimum credit quality criteria established in each of WGSW’s agreements. These criteria must be satisfied for WGSW to participate in the project financing arrangement or partnership interest.

WGL Midstream is not subject to retail credit risk.

MARKET RISK

We are exposed to various forms of market risk including commodity price risk, weather risk and interest-rate risk. The following discussion describes these risks and our management of them.

Price Risk Related to the Regulated Utility Segment

Washington Gas faces price risk associated with the purchase and sale of natural gas. Washington Gas generally recovers the cost of the natural gas to serve customers through gas cost recovery mechanisms as approved in jurisdictional tariffs; therefore, a change in the price of natural gas generally has no direct effect on Washington Gas’ net income. However, Washington Gas is responsible for following competitive and reasonable practices in purchasing natural gas for its customers.

To manage price risk associated with its natural gas supply to its firm customers, Washington Gas: (i) actively manages its gas supply portfolio to balance sales and delivery obligations; (ii) injects natural gas into storage during the summer months when prices are historically lower, and withdraws that gas during the winter heating season when prices are historically higher and (iii) enters into hedging contracts and other contracts that qualify as derivative instruments related to the sale and purchase of natural gas.

Washington Gas executes commodity-related physical and financial contracts in the form of forward, futures and option contracts as part of an asset optimization program that is managed by its internal staff. Under this program, Washington Gas realizes value from its long-term natural gas transportation and storage capacity resources when not being fully used to serve utility customers. Regulatory sharing mechanisms in all three jurisdictions allow the profit from these transactions to be shared between Washington Gas’ customers and shareholders.

The following two tables summarize the changes in the fair value of our net assets (liabilities) associated with the Regulated Utility segment’s energy-related derivatives during the six months ended March 31, 2015:

Price Risk Related to the Non-Utility Segments

Retail Energy-Marketing. Our retail energy-marketing subsidiary, WGL Energy Services, sells natural gas and electricity to retail customers at both fixed and indexed prices. WGL Energy Services must manage daily and seasonal demand fluctuations for these products with its suppliers. Price risk may exist to the extent WGL Energy Services does not closely match the timing and volume of natural gas and electricity it purchases with the related fixed price or indexed sales commitments. WGL Energy Services’ risk management policies and procedures are designed to minimize this risk.

A portion of WGL Energy Services’ annual natural gas sales volumes is subject to variations in customer demand associated with fluctuations in weather and other factors. Purchases of natural gas to fulfill retail sales commitments are generally made under fixed-volume contracts based on certain weather assumptions. If there is significant deviation from normal weather or from other factors that affect customer usage, purchase commitments may differ significantly from actual customer usage. To the extent that WGL Energy Services cannot match its customer requirements and supply commitments, it may be exposed to commodity price and volume variances, which could negatively impact expected gross margins (refer to the section entitled “Weather Risk” for a further discussion of our management of weather risk). WGL Energy Services manages these risks through the use of derivative instruments, including financial products.

WGL Energy Services procures electricity supply under contract structures in which WGL Energy Services assumes the responsibility of matching its customer requirements with its supply purchases. WGL Energy Services assembles the various components of supply, including electric energy from various suppliers, and capacity, ancillary services and transmission service from the PJM Interconnection, a regional transmission organization, in matching its customer requirements obligations. While the capacity and transmission costs within PJM are generally stable and identifiable several years into the future, the cost of ancillary services which support the reliable operation of the transmission system does fluctuate as changes occur in the balance between generation and the consumption mix within the electric system. WGL Energy Services could be exposed to price risk associated with changes in ancillary costs due to lack of available forward market products to sufficiently hedge those risks. Commercial retail contracts for larger customers often include terms which permit WGL Energy Services to pass through regulatory approved changes in capacity and transmission costs, as well as some changes in ancillary costs. These terms reduce the price risk exposure related to these changes for WGL Energy Services.

To the extent WGL Energy Services has not sufficiently matched its customer requirements with its supply commitments, it could be exposed to electricity commodity price risk. WGL Energy Services manages this risk through the use of derivative instruments, including financial products.

WGL Energy Services’ electric business is also exposed to fluctuations in weather and varying customer usage. Purchases generally are made under fixed-price, fixed-volume contracts that are based on certain weather assumptions. If there are significant deviations in weather or usage from these assumptions, WGL Energy Services may incur price and volume variances that could negatively impact expected gross margins (refer to the section entitled “Weather Risk” for a further discussion of our management of weather risk).

Commercial Energy Systems. WGL Energy Systems sells electricity and SRECs from distributed generation assets. The sale of electricity is under long term power purchase agreements (PPAs) with a general duration of 20 years, while the sale of SRECs are usually under short term or immediate delivery contracts. Price risk exists through the components used to achieve the target rate of return because the electricity price is based on the cost of the distributed generation assets. Price risk also exists to the extent the sale of SRECs are at prices less than planned or expected prices included in the project design. WGL Energy Systems manages this price risk through the execution of PPAs for the sale of electricity and forward sales of SRECs when possible.

WGSW holds project financing arrangements and a limited partnership interest associated with distributed generating solar assets for a fair market value based on an independent appraisal. The project financing arrangements allow WGSW to lease back those solar assets to the counterparty with a fixed target rate of return over a period of 6-20 years. Price risk exists through the components used to achieve the target rate of return since the components are based on market leasing prices for retail customers and cost of solar panels. Similarly, in WGSW’s limited partnership interest, solar assets are purchased by and leased to retail customers through the partnership. The purchased solar assets are expected to achieve a target rate of return from the lease payments being collected from the retail customers, therefore the price risk exists between the leasing prices for solar assets and the purchase price of the solar assets. WGSW manages this price risk through its investment agreements and evaluation of the asset purchase in conjunction with the inception of the lease.

Midstream Energy Services. WGL Midstream engages in wholesale commodity transactions to optimize its owned and managed natural gas assets. Price risk exists to the extent WGL Midstream does not closely match the volume of physical natural gas in storage with the related forward sales entered into as hedges. WGL Midstream mitigates this risk by actively managing and hedging these assets in accordance with corporate risk management policies and procedures. Depending upon the nature of its forward hedges, WGL Midstream may also be exposed to fluctuations in mark-to-market valuations based on changes in forward price curves. WGL Midstream pays fixed, fair market prices for its owned storage assets and is subject to variations in annual summer-winter spreads associated with weather and other market factors. To the extent there are significant variations in weather, WGL Midstream may incur price variances that negatively impact expected gross margins (refer to the section entitled “Weather Risk” for a further discussion of our management of weather risk). WGL Midstream manages this risk through the use of derivative instruments, including financial products.

Value-at-Risk

WGL Energy Services measures the market risk of its energy commodity portfolio by determining its value-at-risk. Value-at-risk is an estimate of the maximum loss that can be expected at some level of probability if a portfolio is held for a given time period. The value-at-risk calculation for natural gas and electric portfolios include assumptions for normal weather, new customers and renewing customers for which supply commitments have been secured. Based on a 95% confidence interval for a one-day holding period, WGL Energy Services’ value-at-risk at March 31, 2015 was approximately $33,600 and $19,900, related to its natural gas and electric portfolios, respectively. WGL Energy Services’ value-at-risk for the natural gas and electric portfolios fluctuate relative to market prices and portfolio composition. The high, low and average value-at-risk for natural gas and electric portfolios between the period October 1, 2014 and March 31, 2015 are noted in the table below.



WGL Energy Services Value-at-Risk
(In thousands)	High		Low		Average
Natural Gas	$	100.2	$	23.6	$	54.8
Electric Portfolio	95.6		11.2		36.7
Total	$	195.8	$	34.8	$	91.5

Weather Risk

We are exposed to various forms of weather risk in both our regulated utility and non-utility business segments. To the extent Washington Gas does not have weather related instruments or billing adjustment mechanisms in place, its revenues are volume driven and its current rates are based upon an assumption of normal weather. Without weather protection strategies, variations from normal weather will cause our earnings to increase or decrease depending on the weather pattern.

The financial results of our retail energy-marketing business, WGL Energy Services, are affected by variations from normal weather primarily in the winter relating to its natural gas sales, and throughout the fiscal year relating to its electricity sales. WGL Energy Services manages these weather risks with, among other things, weather related instruments.

Variations from normal weather may also affect the financial results of our wholesale energy business, WGL Midstream, primarily with regards to summer-winter storage spreads and in transportation spreads throughout the fiscal year. WGL Midstream manages these weather risks with, among other things, location, physical and financial basis hedging.

Billing Adjustment Mechanisms. In Maryland, Washington Gas has a Revenue Normalization Adjustment (RNA) billing mechanism that is designed to stabilize the level of net revenues collected from Maryland customers by eliminating the effect of deviations in customer usage caused by variations in weather from normal levels and other factors such as conservation. In Virginia, Washington Gas has a Weather Normalization Adjustment (WNA) billing adjustment mechanism that is designed to eliminate the effect of variations in weather from normal levels on utility net revenues. Additionally, in Virginia, as part of the Conservation and Ratemaking Efficiency (CARE) plan, Washington Gas has a CARE Ratemaking Adjustment (CRA) mechanism that, in conjunction with the WNA, eliminates the effect of both weather and other factors such as conservation for residential, small commercial and industrial and group metered apartment customers.

For the RNA, WNA and CRA mechanisms, periods of colder-than-normal weather generally would cause Washington Gas to record a reduction to its revenues and establish a refund liability to customers, while the opposite would generally result during periods of warmer-than-normal weather. However, factors such as volatile weather patterns and customer conservation may cause the RNA and the CRA mechanisms to function conversely because they adjust billed revenues to provide a designed level of net revenue per meter.

Weather-Related Instruments. There were no derivative instruments hedging variations from normal weather in the District of Columbia for the six months ended March 31, 2015 for Washington Gas.

WGL Energy Services utilizes heating degree day (HDD) instruments from time to time to manage weather risks related to its natural gas and electricity sales. WGL Energy Services also utilizes cooling degree day (CDD) instruments and other instruments to manage weather and price risks related to its electricity sales during the summer cooling season. These instruments cover a portion of WGL Energy Services’ estimated revenue or energy-related cost exposure to variations in HDDs or CDDs. Refer to Note 8—Derivative and Weather Related Instruments of the Notes to Consolidated Financial Statements for further discussion of the accounting for these weather-related instruments.

Interest-Rate Risk

We are exposed to interest-rate risk associated with our short-term and long-term financing. WGL utilizes derivative instruments from time to time in order to minimize its exposure to the risk of interest-rate volatility.

Short-Term Debt. At March 31, 2015 and September 30, 2014, WGL and its subsidiaries had outstanding notes payable of $175.0 million and $453.5 million, respectively. The carrying amount of our short-term debt approximates fair value. In the current quarter, a change of 100 basis points in the underlying average interest rate for our short-term debt would have caused a change in interest expense of approximately $2.2 million.

Long-Term Debt. At March 31, 2015, we had outstanding fixed-rate MTNs and other long-term debt of $950.5 million, excluding current maturities and unamortized discounts. While fixed-rate debt does not expose us to earnings risk when market interest rates change, such debt is subject to changes in fair value. Fair value is defined as the present value of the debt securities’ future cash flows discounted at interest rates that reflect market conditions as of the measurement date. As of March 31, 2015, the fair value of WGL’s fixed-rate debt was $1,117.9 million. Our sensitivity analysis indicates that fair value would increase by approximately $48.0 million or decrease by approximately $44.4 million if interest rates were to decline or increase by 10%, respectively, from current market levels. As of March 31, 2015, the fair value of Washington Gas’ fixed-rate debt was $864.1 million. Our sensitivity analysis indicates that fair value would increase by approximately $35.3 million or decrease by approximately $33.0 million if interest rates were to decline or increase by 10%, respectively, from current market levels. In general, such an increase or decrease in fair value would impact earnings and cash flows only if WGL or Washington Gas were to reacquire some or all of these instruments in the open market prior to their maturity.

A total of $802.5 million, or approximately 84.8%, of WGL’s outstanding long-term debt, excluding current maturities, have make-whole call options which, if exercised, would require us to pay a premium over the face amount.

A total of $552.5 million, or approximately 79.4%, of Washington Gas’ outstanding MTNs, excluding current maturities, have make-whole call options which, if exercised, would require us to pay a premium over the face amount.

Derivative Instruments. WGL and Washington Gas utilize derivative instruments from time to time in order to minimize its exposure to the risk of interest-rate volatility. During September 2014, WGL entered into interest rate swaps associated with its $150.0 million 30-year debt issuance. WGL elected cash flow hedge accounting for these interest rate derivative instruments. Therefore, the effective portion of the gains and losses on the hedge were recorded within other comprehensive income and will be amortized over the life of the underlying debt (through 2044). In connection with the issuance of $125.0 million of debt on October 22, 2014, WGL settled a portion of the interest rate hedge for a loss of $7.7 million. On December 15, 2014, WGL settled the remaining portion of the outstanding interest rate swap when it issued $25.0 million of MTN’s, for a loss of $2.6 million. During the three months ended March 31, 2015, nil was recorded to income as a result of the ineffective portion of the interest rate swap. During the six months ended March 31, 2015, a total of $0.4 million was recorded to income as a result of the ineffective portion of the interest rate swap. Refer to the section entitled “Long-Term Cash Requirements and Related Financing” for further discussion of our interest-rate risk management activity.

WASHINGTON GAS LIGHT COMPANY

This section of Management’s Discussion focuses on Washington Gas for the reported periods. In many cases, explanations and disclosures for both WGL and Washington Gas are substantially the same.

RESULTS OF OPERATIONS—Three Months Ended March 31, 2015 vs. March 31, 2014

The results of operations for the Regulated Utility segment and Washington Gas are substantially the same; therefore, this section primarily focuses on statistical information and other information that is not discussed in the results of operations for the Regulated Utility segment. Refer to the section entitled “Results of Operations—Regulated Utility” in Management’s Discussion for WGL for a detailed discussion of the results of operations for the Regulated Utility segment.

Key gas delivery, weather and meter statistics are shown in the table below for the three months ended March 31, 2015 and 2014.

Gas Service to Firm Customers. The volume of gas delivered to firm customers is highly sensitive to weather variability as a large portion of the natural gas delivered by Washington Gas is used for space heating. Washington Gas’ rates are based on an assumption of normal weather. The RNA in Maryland and the WNA and CARE Ratemaking Adjustment (CRA) in Virginia are mechanisms designed to, among other things, eliminate the effect on net revenues of variations in weather from normal levels (refer to the section entitled “Weather Risk” for a further discussion of these mechanisms and other weather-related instruments included in our weather protection strategy).

This comparison in natural gas deliveries to firm customers primarily reflects colder weather in the current quarter than in the same quarter of the prior year and an increase in average active customer meters of 12,843.

Gas Service to Interruptible Customers. Washington Gas must curtail or interrupt service to this class of customer when the demand by firm customers exceeds specified levels.

In the District of Columbia, the effect on net income of any changes in delivered volumes and prices to interruptible customers is limited by margin-sharing arrangements that are included in Washington Gas’ firm rate designs. Rates for interruptible customers in Maryland and Virginia are based on a traditional cost of service approach. In Virginia, Washington Gas retains a majority of the margins earned on interruptible gas and delivery sales. Washington Gas shares actual non-gas

WGL Holdings, Inc.

Washington Gas Light Company

Part I—Financial Information

Item 2—Management’s Discussion and Analysis of

Financial Condition and Results of Operations (continued)

margins from interruptible sales service customers that are in excess of delivery service rates. In Maryland, Washington Gas retains a defined amount of revenues based on a set threshold.

Gas Service for Electric Generation. Washington Gas delivers natural gas for use at two electric generation facilities in Maryland that are each owned by companies independent of WGL. Washington Gas shares with firm customers a significant majority of the margins earned from natural gas deliveries to these customers. Therefore, changes in the volume of interruptible gas deliveries to these customers do not materially affect either net revenues or net income.

Interest Expense

The following table shows the components of Washington Gas' interest expense for the three months ended March 31, 2015 and 2014. The increase in interest on long-term debt primarily comprises private placements notes and unsecured MTNs issued by Washington Gas.

LIQUIDITY AND CAPITAL RESOURCES

Liquidity and capital resources for Washington Gas are substantially the same as the liquidity and capital resources discussion included in the Management’s Discussion of WGL (except for certain items and transactions that pertain to WGL and its unregulated subsidiaries). Those explanations are incorporated by reference into this discussion.

RATES AND REGULATORY MATTERS

Washington Gas makes its requests to modify existing rates based on its determination of the level of net investment in plant and equipment, operating expenses, and a level of return on invested capital that is just and reasonable. The following is an update of significant current regulatory matters in each of Washington Gas’ jurisdictions. For a more detailed discussion of the matters below, refer to our combined Annual Report on Form 10-K for WGL and Washington Gas for the fiscal year ended September 30, 2014.

District of Columbia Jurisdiction

Accelerated Pipe Replacement Plan. On August 15, 2013, Washington Gas filed a request for approval with the Public Service Commission of the District of Columbia (PSC of DC) of a Revised Accelerated Pipe Replacement Plan (APRP), including a surcharge mechanism to recover the associated costs for the first five years of the plan. Washington Gas proposed to replace bare and/or unprotected steel services, bare and targeted unprotected steel main, and cast iron main in its distribution system in the District of Columbia at an estimated five-year cost of $110 million. The PSC of DC granted final approval of the APRP in August 2014, but opened a separate proceeding to consider the issue of the appropriate APRP cost recovery mechanism. On December 10, 2014, Washington Gas filed a joint motion, on behalf of all parties to the proceeding, requesting

WGL Holdings, Inc.

Washington Gas Light Company

Part I—Financial Information

Item 2—Management’s Discussion and Analysis of

Financial Condition and Results of Operations (continued)

approval of a unanimous settlement agreement on the cost recovery issue. The settlement agreement authorizes a surcharge to recover the costs of the first five years of the accelerated pipe replacement program, including replacement activity starting in June of 2014. On January 29, 2015, the PSC of DC issued an order approving the settlement agreement.

Investigation into Washington Gas’ cash reimbursement to Competitive Service Providers (CSPs). On August 5, 2014, the Office of the People’s Counsel’s (“OPC”) of DC filed a complaint with the PSC of DC requesting that the Commission open an investigation into Washington Gas’ payments to CSPs who over-delivered natural gas supplies by $2.4 million during the 2008-2009 winter heating season. On December 19, 2014, the PSC of DC granted the OPC of DC’s request and opened a formal investigation.

Weather Normalization Adjustment. On November 8, 2013, Washington Gas filed an application for approval of a Weather Normalization Adjustment (WNA) before the PSC of DC. The proposal would authorize Washington Gas to implement a rate design mechanism that would eliminate the variability of weather from the calculation of revenues and offer customers more stability in their bills, during colder than normal winter heating season. On April 10, 2015, the PSC of DC denied Washington Gas' application for approval of a WNA, indicating that Washington Gas may request a WNA in its next base rate case.

Maryland Jurisdiction

Maryland Strategic Infrastructure Development and Enhancement Plan. On November 7, 2013, pursuant to the STRIDE law in Maryland, Washington Gas filed an application with the PSC of MD for authority to implement a STRIDE Plan and to recover the reasonable and prudent costs associated with the infrastructure replacements through monthly surcharges. On May 6, 2014, the PSC of MD issued an order approving Washington Gas' first STRIDE Plan. On June 5, 2014, the Maryland Office of People’s Counsel filed an appeal of the PSC of MD’s May 6, 2014 order with the Circuit Court for Baltimore City. Washington Gas filed a notice on June 13, 2014 that it intended to participate in the appeal. On October 29, 2014, the parties to the appeal jointly requested that the proceedings be stayed pending the outcome of the appeal of a Baltimore Gas & Electric Company case that may be dispositive of the issues in the Washington Gas proceeding.

On December 18, 2014, the PSC of MD issued a letter order approving Washington Gas’ 2015 STRIDE project list targeting approximately $37 million in capital expenditures and surcharge factor subject to adjustments made by the staff of the PSC.

On March 10, 2015, Washington Gas filed an application with the PSC of MD for approval of an amendment to the approved STRIDE Plan. Washington Gas requested approval to add one additional program applicable to gas distribution system replacements and four additional programs applicable to gas transmission system replacements at an incremental investment of $31.2 million in eligible infrastructure replacements over the remaining four years of the STRIDE Plan. This application is pending review by the PSC of MD. A decision is expected within 120 days of the filing date.

Virginia Jurisdiction

Affiliate Transactions. On June 5, 2013, Washington Gas submitted a petition for declaratory judgment with the SCC of VA related to a proposed transfer to WGL Midstream of the remainder of the term of two agreements for natural gas storage service at the Washington Storage Service (WSS) and Eminence Storage Service (ESS) storage fields. Specifically, Washington Gas sought a declaratory judgment that the SCC of VA did not have jurisdiction over the proposed transaction since the WSS and ESS agreements were no longer utilized to provide utility service and the SCC of VA was preempted by the federal authority over the transfers. On April 15, 2015, the SCC of VA approved the transfer of WSS and ESS but did not issue a ruling on the request for declaratory judgment.

Steps to Advance Virginia's Energy Plan (SAVE) - Plan Amendment. On February 6, 2015, Washington Gas submitted an application to the SCC of VA requesting approval to amend its SAVE Plan to expand the scope of some existing programs, to include new distribution facilities replacement programs, and to add new programs to replace transmission facilities. Washington Gas proposed investing an additional $75.2 million to replace Virginia eligible infrastructure over the 2015-2017 period. This application is pending review by the SCC of VA. A decision is expected within 120 days of the filing date.

VA Gas Reserves. In the 2014 Session, the General Assembly of the Commonwealth of Virginia amended Title 56 of the Virginia Code. The legislative provisions are intended to encourage regulated utilities to invest in natural gas reserves, upstream pipelines and facilities that are reasonably expected to benefit customers by lowering costs, reducing volatility or lowering the utility’s supply risk. A regulated utility company can obtain the recovery through its rates charged to customers for the entire incurred cost, including the return of and the return on the investment in reserves, as well as all operating costs.

Item 2—Management’s Discussion and Analysis of

Financial Condition and Results of Operations (continued)

The purchase of the reserves is conditional upon approval by the SCC of VA. WGL will submit a filing to the SCC of VA for approval of the investment, with a decision due within 180 days from filing.

OTHER MATTERS

New Labor Contract. Washington Gas has entered into a new five-year labor contract with the Teamsters Local Union No. 96 (Local 96), a union affiliated with the International Brotherhood of Teamsters. The contract covers approximately 520 employees. The Teamsters ratified the contract on April 30, 2015 and is effective from June 1, 2015 through May 31, 2020. The contract includes, among other things: (i) annual wage increases from 2.75% to 3.25% and (ii) employment protection for each Local 96 employee from the date of commencement of the contract.
