   applications with the Public Service Commission of the District of Columbia (PSC of DC) requesting
   approval of proposed revisions to the balancing charge provisions of its firm and interruptible
   delivery service tariffs that would permit the utility to recover from its delivery service
   customers the costs of HHCs that are being injected into Washington Gas&amp;#8217;s natural gas distribution
   system to treat vaporized liquefied natural gas from the Dominion Cove Point Facility. Washington
   Gas had been recovering the costs of HHCs from sales customers in the District of Columbia through
   its Purchased Gas Charge (PGC)&amp;#160;provision in this jurisdiction. On October&amp;#160;2, 2006, the PSC of DC
   issued an order rejecting Washington Gas&amp;#8217;s proposed
   tariff revisions until the Public Service Commission of
   Maryland (PSC of MD) issued a final order
   related to this matter. On October&amp;#160;12, 2006, Washington Gas filed a motion for clarification
   requesting that the PSC of DC affirm that Washington Gas can continue collecting HHC costs from
   sales customers through its PGC provision or to record such HHC costs incurred as a regulatory
   asset pending a ruling by the PSC of DC on future cost recovery. On May&amp;#160;11, 2007, the PSC of DC
   directed Washington Gas to cease prospective recovery of the cost of HHCs through the PGC
   provision, with future HHC costs to be recorded as a &amp;#8220;pending&amp;#8221; regulatory asset. On November&amp;#160;16,
   2007 the PSC of MD issued a final order in the relevant case supporting full recovery of the HHC
   costs in Maryland. On March&amp;#160;25, 2008, the PSC of DC issued an order stating that the consideration
   of Washington Gas&amp;#8217;s HHC strategy will move forward and directed interested parties to submit
   filings reflecting a proposed procedural schedule. On June&amp;#160;6, 2008, Washington Gas and the District
   of Columbia Office of the People&amp;#8217;s Counsel (DC OPC) filed a joint response to the order proposing a
   procedural schedule and a list of issues for consideration in the case. The PSC of DC adopted the
   proposed issues list and approved a procedural schedule. Washington Gas and other parties
   subsequently filed comments, conducted discovery and the parties filed reply comments. On April&amp;#160;30,
   2009, the PSC of DC ruled that there were unresolved issues and directed that they should be
   addressed in evidentiary hearings. The PSC of DC issued an order establishing a procedural schedule
   to address these unresolved issues in the case. Initial testimony was filed May&amp;#160;29, 2009, and
   rebuttal testimony was filed on July&amp;#160;24, 2009.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;On October&amp;#160;2, 2009, Washington Gas and the DC OPC filed a Joint Motion for Approval of
   Unanimous Agreement of Stipulation and Full Settlement with the PSC of DC (Stipulation). The
   parties to the Stipulation agreed that hexane (an HHC) commodity costs incurred by Washington Gas
   to condition liquefied natural gas received in Washington Gas&amp;#8217;s natural gas system are recoverable
   expenses and that Washington Gas is authorized to achieve full cost recovery from sales and
   delivery service customers of hexane commodity costs incurred prior to September&amp;#160;30, 2009.
   Additionally, the Stipulation:
   &lt;/div&gt;

       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;approves the recovery of hexane commodity costs incurred after September&amp;#160;30, 2009 from
   sales and delivery service customers, subject to review as a component of Washington Gas&amp;#8217;s
   cost of gas;&lt;/td&gt;
   &lt;/tr&gt;

       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;establishes a coupling replacement and encapsulation program (program), wherein
   Washington Gas will replace or encapsulate a portion of its mechanically coupled pipe in the
   District of Columbia. The program is expected to conclude in approximately seven years with
   total spending not to exceed $28.0&amp;#160;million;&lt;/td&gt;
   &lt;/tr&gt;
   &lt;tr&gt;
       &lt;td style="font-size: 6pt"&gt;&amp;#160;&lt;/td&gt;

       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;provides for the cost of the program to be recovered through an annual surcharge based
   on actual expenditures for coupling replacement and encapsulation that will become effective
   at the end of the existing base rate freeze (October&amp;#160;1, 2011). The cost will include both a
   return of and return on the cost of coupling replacement and encapsulation, computed in
   accordance with the terms of the rates currently in effect and&lt;/td&gt;
   &lt;/tr&gt;

       &lt;td width="1%"&gt;&amp;#160;&lt;/td&gt;
       &lt;td&gt;establishes periodic reporting on the level of hexane injected at each of Washington
   Gas&amp;#8217;s hexane facilities with the associated commodity costs, and continued filing of
   leak-related information with the PSC of DC.&lt;/td&gt;
   &lt;/tr&gt;
   &lt;/table&gt;
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;On October&amp;#160;16, 2009, the PSC of DC published a Notice of Public Interest Hearing, held on
   October&amp;#160;28, 2009. On December&amp;#160;16, 2009, the PSC of DC issued a final order approving the settlement
   agreement, including recovery of hexane commodity costs, provided the parties agree to change the
   September&amp;#160;30, 2009 date to the effective date of the newly approved tariffs. The parties filed the
   modified language consistent with the final order. Pursuant to the final order, Washington Gas
   established a regulatory asset by reversing hexane costs previously expensed of $0.7&amp;#160;million into
   income.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;As of June&amp;#160;30, 2010 Washington Gas has incurred cumulative total hexane costs of $2.5&amp;#160;million
   related to the District of Columbia of which approximately $1.0&amp;#160;million has been recovered and $1.5
   million has been deferred as a regulatory asset.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;b&gt;&lt;i&gt;Revenue Normalization Adjustment. &lt;/i&gt;&lt;/b&gt;On December&amp;#160;21, 2009, Washington Gas filed a revised tariff
   application seeking approval of an RNA, a sales adjustment mechanism that decouples Washington
   Gas&amp;#8217;s non-gas revenues from actual delivered volumes of gas. On December&amp;#160;22, 2009, the DC OPC filed
   a motion requesting that the PSC of DC establish public hearing procedures to examine the merits of
   Washington Gas&amp;#8217;s RNA application. Washington Gas filed an opposition to the DC OPC&amp;#8217;s motion on
   January&amp;#160;4, 2010. The PSC of DC issued an order on January&amp;#160;19, 2010 granting the DC OPC&amp;#8217;s motion for
   evidentiary hearing and initiated a rate proceeding to consider issues surrounding Washington
   Gas&amp;#8217;s tariff application. On April&amp;#160;2, 2010, the
   PSC of DC issued an order designating issues to be
   addressed and establishing a procedural schedule for the case. Washington Gas filed supplemental
   testimony on April&amp;#160;13, 2010. The DC OPC, the District of Columbia Office of the Environment (DC
   Government) and the Apartment and Office Building Association of Metropolitan Washington (AOBA)
   filed direct testimony on May&amp;#160;17, 2010. Washington Gas filed rebuttal testimony on June&amp;#160;29, 2010.
   Evidentiary hearings were held on July&amp;#160;27-28, 2010.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 10pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;b&gt;Maryland Jurisdiction&lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;b&gt;&lt;i&gt;Order on and Reviews of Purchased Gas Charges. &lt;/i&gt;&lt;/b&gt;Each year, the PSC of MD reviews the annual gas
   costs collected from customers in Maryland to determine if Washington Gas&amp;#8217;s purchased gas costs are
   reasonable. On March&amp;#160;14, 2006, in connection with the PSC of MD&amp;#8217;s annual review of Washington Gas&amp;#8217;s
   gas costs that were billed to customers in Maryland from September&amp;#160;2003 through August&amp;#160;2004, a
   Hearing Examiner of the PSC of MD issued a proposed order approving purchased gas charges of
   Washington Gas for the twelve-month period ended August&amp;#160;2004, except for $4.6&amp;#160;million of such
   charges that the Hearing Examiner recommended be disallowed because, in the opinion of the Hearing
   Examiner, they were not reasonably incurred. As a result, during the fiscal year ended September
   30, 2006, Washington Gas accrued a liability of $4.6&amp;#160;million related to the proposed disallowance
   of these purchased gas charges.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Washington Gas filed appeals with the PSC of MD asserting that the Hearing Examiner&amp;#8217;s
   recommendation was without merit. On February&amp;#160;5, 2009, the PSC of MD issued an order that granted
   the appeal and reversed the findings of the Hearing Examiner. Accordingly, the gas costs at issue
   were deemed recoverable from rate payers. The PSC of MD&amp;#8217;s order concluded that the responsibility
   for recovery of these costs should be assigned to the specific group of customers associated with
   unbundled firm delivery service, directing Washington Gas to bill such costs to those customers
   over a 24-month period and to provide a credit to firm bundled sales customers over the same
   period. As a result of this order, the liability recorded in fiscal year 2006 for this issue was
   reversed in the quarter ended December&amp;#160;31, 2008, and Washington Gas recorded income of $4.6&amp;#160;million
   to &amp;#8220;Operating revenues-utility.&amp;#8221; On February&amp;#160;25, 2009, Washington Gas filed its compliance plan
   with the PSC of MD which outlined the plan for returning these funds to its firm sales customers,
   as well as collecting funds from firm delivery service customers beginning with Washington Gas&amp;#8217;s
   May&amp;#160;2009 billing cycle and ending with its April&amp;#160;2011 billing cycle. On April&amp;#160;29, 2009, the PSC of
   MD approved Washington Gas&amp;#8217;s plan.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;A hearing was held March&amp;#160;27, 2009 on Washington Gas&amp;#8217;s purchased gas charges for the twelve
   month period ended August&amp;#160;31, 2008. No party challenged Washington Gas&amp;#8217;s gas costs incurred during
   the period, but the Staff of the PSC of MD (MD Staff) and the PSC of MD Office of the People&amp;#8217;s
   Counsel (MD OPC) requested that the case remain open subject to any changes that may result from
   the final PSC of MD order regarding Washington Gas&amp;#8217;s asset management and gas purchase practices
   (refer to the section entitled &lt;i&gt;&amp;#8220;Investigation of Asset Management and Gas Purchase Practices&amp;#8221; &lt;/i&gt;for a
   further discussion of this case). On April&amp;#160;23, 2010, the Hearing Examiner issued a Proposed Order
   which approved Washington Gas&amp;#8217;s gas costs for the period, subject to any changes which may arise
   from the Commission&amp;#8217;s final order in the asset management investigation in Case No.&amp;#160;9158. The
   Proposed Order was not appealed by any party and became a final order of the Commission on May&amp;#160;25,
   2010.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;A hearing was held on March&amp;#160;25, 2010 on Washington Gas&amp;#8217;s purchased gas charges for the twelve
   month period ended August&amp;#160;31, 2009. The parties filed initial briefs on April&amp;#160;30, 2010 and reply
   briefs on May&amp;#160;21, 2010. The Staff of the PSC of MD and the MD OPC are challenging a portion of the
   Company&amp;#8217;s gas costs averring that the Company did not have authority under its tariff to cash-out
   over-deliveries by suppliers over the 12-months ended March&amp;#160;2009 and also asserting that the
   Company used an&amp;#8221; excessive price&amp;#8221; as the cash-out price. Staff recommends that a second phase to
   the proceeding be initiated to investigate these assertions. The Company has denied both these
   assertions. The parties are awaiting a decision from the Hearing Examiner.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 10pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;b&gt;Virginia Jurisdiction&lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;b&gt;&lt;i&gt;Conservation and Ratemaking Efficiency Plan. &lt;/i&gt;&lt;/b&gt;On September&amp;#160;29, 2009, Washington Gas filed with
   the Virginia State Corporation Commission (SCC of VA) an application which included a portfolio of
   conservation and energy efficiency programs, an associated cost recovery provision and a decoupling
   mechanism which will adjust weather normalized non-gas distribution revenues for the impact of
   conservation or energy efficiency efforts. An evidentiary hearing in the proceeding was held on
   February&amp;#160;9, 2010. On March&amp;#160;26, 2010 the SCC of VA issued an Order approving a
   decoupling rate mechanism for residential
   customers and six residential energy efficiency programs
   and the cost recovery mechanism for those programs. Washington Gas filed compliance tariffs with
   the Staff of the SCC of VA on April&amp;#160;19, 2010 to implement the Conservation and Ratemaking
   Efficiency Plan on May&amp;#160;1, 2010. The Company began applying the decoupling mechanism in Virginia in its July billings
   consistent with the Commission&amp;#8217;s approval.
    On July&amp;#160;22, 2010,
   Washington Gas filed an amendment to the conservation and ratemaking efficiency (CARE) Plan to include small commercial and industrial
   customers in Virginia. The application included a portfolio of conservation and energy efficiency
   programs, an associated cost recovery provision and a decoupling mechanism and will adjust weather
   normalized non-gas distribution revenues for the impact of conservation or energy efficiency
   efforts. The Company is currently awaiting the establishment of a docket number and procedural
   schedule.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 10pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;b&gt;&lt;i&gt;Performance-Based Rate Plans&lt;/i&gt;&lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In rate case proceedings in all jurisdictions, Washington Gas requested permission to
   implement Performance-Based Rate (PBR)&amp;#160;plans that include performance measures for customer service
   and an Earnings Sharing Mechanism (ESM)&amp;#160;that enables Washington Gas to share with shareholders and
   customers the earnings that exceed a target rate of return on equity.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Effective October&amp;#160;1, 2007, the SCC of VA approved the implementation of a PBR plan through the
   acceptance of a settlement stipulation, which includes: &lt;i&gt;(i) &lt;/i&gt;a four-year base rate freeze; &lt;i&gt;(ii)&lt;/i&gt;
   service quality measures to be determined in conjunction with the Staff of the SCC of VA and
   reported quarterly for maintaining a safe and reliable natural gas distribution system while
   striving to control operating costs; &lt;i&gt;(iii) &lt;/i&gt;recovery of initial implementation costs associated with
   achieving Washington Gas&amp;#8217;s business process outsourcing (BPO)&amp;#160;initiatives over the four-year period
   of the PBR plan and &lt;i&gt;(iv) &lt;/i&gt;an ESM that enables Washington Gas to share with shareholders and Virginia
   customers the earnings that exceed a target of 10.5% return on equity. The calculation of the ESM
   excludes $2.4&amp;#160;million of asset management revenues that are being refunded to customers as part of
   a new margin sharing agreement in Virginia.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;On May&amp;#160;4, 2009, the Staff of the SCC of VA issued a report, commenting on the amount of the
   ESM liability that had been reported for the fiscal year ending September&amp;#160;30, 2008. Washington Gas
   filed its response to the Staff report on June&amp;#160;18, 2009. On July&amp;#160;17, 2009, Washington Gas and the
   Staff of the SCC of VA filed a joint motion to approve stipulation and close proceeding with the
   SCC of VA whereby the Staff of the SCC of VA and Washington Gas agreed upon the appropriate refund
   to ratepayers under the ESM. The overall difference between the Staff position and Washington Gas&amp;#8217;s
   position was not material to the financial statements of Washington Gas. On July&amp;#160;24, 2009, the SCC
   of VA granted the joint motion and accepted the stipulation submitted by Washington Gas and the
   Staff of the SCC of VA in its final order approving the ESM liability for fiscal year 2008. In
   accordance with the provisions of its VA tariff, Washington Gas began crediting customers&amp;#8217; bills in
   April&amp;#160;2009 for the fiscal year 2008 ESM liability. The credits continued through March, 2010. At
   June&amp;#160;30, 2010, Washington Gas had fully refunded the ESM liability to its customers.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;On January&amp;#160;28, 2010, Washington Gas filed its annual information filing indicating that there
   was no ESM liability for fiscal year 2009. On May&amp;#160;24, 2010 the Staff issued its report to the SCC
   of VA on the annual informational filing and the ESM. The Staff of the SCC of VA concurred with
   Washington Gas that Virginia jurisdictional results did not generate an ESM liability for fiscal
   year 2009. On June&amp;#160;9, 2010 Washington Gas filed notice that it had no comments on the Staff&amp;#8217;s
   report. On June&amp;#160;30, 2010, the SCC of VA accepted the Staff&amp;#8217;s report and agreed that there was no
   ESM liability for fiscal year 2009.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Based on the results reflected in the annual information filing, Washington Gas has recorded
   revenue of approximately $0.5&amp;#160;million of previously expensed hexane costs and on June&amp;#160;23, 2010
   filed an application with the SCC of VA requesting the authority to bill the cost of this hexane to
   customers in accordance with the provision of the Settlement Stipulation in the last rate
   proceeding. The SCC of VA has not issued a procedural schedule in this proceeding. On July&amp;#160;22,
   2010, the Commission issued an Order for Notice and Comment in this proceeding. The Company is
   required to file direct testimony by August&amp;#160;18, 2010 with the Staff&amp;#8217;s Report due October&amp;#160;21, 2010.
   The Company&amp;#8217;s response to the Staff&amp;#8217;s Report is due November&amp;#160;4, 2010.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;On an interim basis, Washington Gas records the effects of the ESM based on year-to-date
   earnings in relation to estimated annual earnings as calculated for regulatory purposes. Based on
   expected results for 2010, no liability has been recognized for
   2010 and Washington Gas has accrued revenue of approximately $1.0&amp;#160;million
   related to the recovery of hexane costs incurred in Virginia in 2010.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;On November&amp;#160;16, 2007, the PSC of MD issued a final order
   in a rate case which established a
   phase-two proceeding to review Washington Gas&amp;#8217;s request to implement a PBR plan and issues raised
   by the parties associated with Washington Gas&amp;#8217;s BPO agreement. On September&amp;#160;4, 2008, a proposed
   order of the Hearing Examiner was issued in this phase-two proceeding. Consistent with Washington Gas&amp;#8217;s
   current accounting methodology, the proposed order approved 10-year amortization accounting for
   initial implementation costs related to Washington Gas&amp;#8217;s BPO plan. At June&amp;#160;30, 2010 and September
   30, 2009, we had recorded a regulatory asset of $6.7&amp;#160;million and $7.4&amp;#160;million, respectively, net of
   amortization, related to initial implementation costs allocable to Maryland associated with our BPO
   plan. Washington Gas&amp;#8217;s application seeking approval of a PBR plan was denied. Additionally, the
   proposed order &lt;i&gt;(i) &lt;/i&gt;directs Washington Gas to obtain an independent management audit related to
   issues raised in the phase-two proceeding and &lt;i&gt;(ii) &lt;/i&gt;directs the initiation of a collaboration
   process in which Washington Gas is directed to engage in discussions with the Staff of the PSC of
   MD (MD Staff), the MD OPC and interested parties to develop appropriate customer service metrics
   and a periodic form for reporting results similar to the metrics filed by Washington Gas as part of
   the approved settlement in Virginia. This proposed order has been appealed by the MD Staff, the MD
   OPC and other parties. Washington Gas&amp;#8217;s reply memorandum on appeal was filed on November&amp;#160;5, 2008. A
   final decision by the PSC of MD is pending.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The final order issued by the PSC of DC on December&amp;#160;28, 2007 approved amortization accounting
   for initial implementation costs related to the BPO plan in approving the stipulated agreement
   filed in the proceeding. As part of that approved agreement, Washington Gas withdrew its
   application seeking approval of a PBR plan. Washington Gas is prohibited from seeking approval of a
   PBR plan in the District of Columbia until the filing of its next base rate case; however, the
   settling parties may not seek a change in rates during the rate case filing moratorium period under
   the terms of the approved rate settlement, with the exception of the implementation of a revenue
   normalization adjustment.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 10pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;b&gt;&lt;i&gt;Depreciation Study&lt;/i&gt;&lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In October&amp;#160;2006, Washington Gas completed a depreciation rate study based on its property,
   plant and equipment balances as of December&amp;#160;31, 2005. The results of the depreciation study
   concluded that Washington Gas&amp;#8217;s depreciation rates should be reduced due to asset lives being
   extended beyond previously estimated lives. Under regulatory requirements, these depreciation rates
   must be approved before they are placed into effect.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;On April&amp;#160;13, 2007, Washington Gas filed the portion of the depreciation study related to the
   Maryland jurisdiction. A separate proceeding was established on May&amp;#160;2, 2007, by the PSC of MD to
   review Washington Gas&amp;#8217;s request to implement new depreciation rates. On October&amp;#160;25, 2007,
   Washington Gas filed a 2007 technical update of the Maryland depreciation study based on property,
   plant and equipment balances as of December&amp;#160;31, 2006. Hearings were held May&amp;#160;12 and 13, 2008.
   Initial briefs were filed on July&amp;#160;16, 2008 and reply briefs were filed on August&amp;#160;6, 2008. On
   October&amp;#160;15, 2008, a proposed order of Hearing Examiner was issued in Maryland, which would reduce
   Washington Gas&amp;#8217;s annual depreciation expense related to the Maryland jurisdiction by approximately
   $11.2&amp;#160;million when new depreciation rates are implemented, with a corresponding decrease in annual
   revenues on a prospective basis to be reflected in future billing rates. Reflected in this
   reduction in depreciation expense, among other things, are: &lt;i&gt;(i) &lt;/i&gt;a change in methodology for
   calculating accrued asset removal costs and &lt;i&gt;(ii) &lt;/i&gt;the designation of certain insurance and
   relocation reimbursements as salvage value. This reduction in depreciation expense will not impact
   annual operating income and will not prevent the recovery of our capital investment; however, it
   will have the effect of deferring full recovery of our capital investment into future years. On
   November&amp;#160;14, 2008, Washington Gas and the MD OPC noted appeals of the October&amp;#160;15, 2008 proposed
   order, thus suspending its effective date.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;On February&amp;#160;5, 2010, the PSC of MD issued an order on appeal. The order affirmed the proposed
   order with two exceptions: &lt;i&gt;(i) &lt;/i&gt;it directed the parties to confer and report on a prospective
   allocation method for reimbursements and &lt;i&gt;(ii) &lt;/i&gt;it directed Washington Gas to amortize its $13.3
   million reserve deficiency imbalance over a 33.5&amp;#160;year time frame. On March&amp;#160;26, 2010, Washington Gas
   made a compliance filing with the PSC of MD to revise its depreciation rates in accordance with the
   Commission&amp;#8217;s February&amp;#160;5, 2010 Order. Under Washington Gas&amp;#8217;s proposed revised depreciation rates,
   annual depreciation expense applicable to Maryland would be reduced by $11,366,000. As required by
   the Commission&amp;#8217;s Order in Washington Gas&amp;#8217;s most recent base rate case in Maryland, as part of its
   compliance filing, Washington Gas also filed revised base rates to reflect the decrease in annual
   depreciation expense
   in Maryland. The MD Staff challenged Washington Gas&amp;#8217;s proposed depreciation rates and supported
   alternative depreciation rates which would reduce depreciation expense by $11,426,000. On May&amp;#160;12,
   2010 the Commission approved the revised depreciation rates and base rates proposed by Staff
   effective June&amp;#160;1, 2010. On May&amp;#160;25, 2010, Washington Gas filed a revised compliance filing
   reflecting the $11,426,000 reduction in base rates.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 10pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;b&gt;NON-UTILITY OPERATIONS&lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;b&gt;&lt;i&gt;Construction Project Financing&lt;/i&gt;&lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;To fund certain of its construction projects, Washington Gas enters into financing
   arrangements with third party lenders. As part of these financing arrangements, Washington Gas&amp;#8217;s
   customers agree to make principal and interest payments over a period of time, typically beginning
   after the projects are completed. Washington Gas assigns these customer payment streams to the
   lender in exchange for the contract payments paid to Washington Gas during the construction period.
   As the lender funds the construction project, Washington Gas establishes a receivable representing
   its customers&amp;#8217; obligations to remit principal and interest and a long-term payable to the lender.
   When these projects are formally &amp;#8220;accepted&amp;#8221; by the customer as completed, Washington Gas transfers
   the ownership of the receivable to the lender and removes both the receivable and the long-term
   financing from its financial statements. As of June&amp;#160;30, 2010, work on these construction projects
   that was not completed or accepted by customers was valued at $6.3&amp;#160;million, which is recorded on
   the balance sheet as a receivable in &amp;#8220;Deferred Charges and Other Assets&amp;#8212;Other&amp;#8221; with the
   corresponding long-term obligation to the lender in &amp;#8220;Long-term debt.&amp;#8221; At any time before these
   contracts are accepted by the customer, should there be a contract default, such as, among other
   things, a delay in completing the project, the lender may call on Washington Gas to fund the unpaid
   principal in exchange for which Washington Gas would receive the right to the stream of payments
   from the customer. Once the project is accepted by the customer, the lender will have no recourse
   against Washington Gas related to this long-term debt.
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 10pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&lt;b&gt;&lt;i&gt;Financial Guarantees&lt;/i&gt;&lt;/b&gt;
   &lt;/div&gt;
   &lt;div align="left" style="font-size: 10pt; margin-top: 6pt"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;WGL Holdings has guaranteed payments for certain purchases of natural gas and electricity on
   behalf of the retail energy-marketing segment. At June&amp;#160;30, 2010, these guarantees totaled $543.6
   million. The amount of such guarantees is periodically adjusted to reflect changes in the level of
   financial exposure related to these purchase commitments. We also receive financial guarantees or
   other collateral from suppliers when required by our credit policy. WGL Holdings has issued
   guarantees related to purchase commitments of its Capitol Energy Ventures subsidiary. At June&amp;#160;30,
   2010, these guarantees totaled $18.0&amp;#160;million. WGL Holdings also issued guarantees totaling $3.0
   million at June&amp;#160;30, 2010 that were made on behalf of certain of our non-utility subsidiaries
   associated with their banking transactions. Of the total guarantees of $564.6&amp;#160;million, $42.0
   million are due to expire on December&amp;#160;31, 2010. The remaining guarantees do not have specific
   maturity dates. For all of its financial guarantees, WGL Holdings may cancel any or all future
   obligations imposed by the guarantees upon written notice to the counterparty; however, WGL
   Holdings would continue to be responsible for the obligations that had been created under the
   guarantees prior to the effective date of the cancellation.
