RELATED PARTY TRANSACTIONS</b> </div> <div align="center" style="font-size: 10pt"> <div style="width: 100%; border-bottom: 1px solid #000000; font-size: 1px">  </div> </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">      WGL Holdings and its subsidiaries engage in transactions among each other during the ordinary course of business. Intercompany transactions and balances have been eliminated from the consolidated financial statements of WGL Holdings. Washington Gas provides accounting, treasury, legal and other administrative and general support to affiliates, and files consolidated tax returns that include affiliated taxable transactions. The actual costs of these services are billed to the appropriate affiliates and, to the extent such billings are not yet paid, they are reflected in “Receivables from associated companies” on Washington Gas’s 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. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">      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 as quickly as reasonably possible. Cash collected by Washington Gas on behalf of its affiliates but not yet transferred is recorded in “Payables to associated companies” on Washington Gas’s balance sheets. These transactions recorded by Washington Gas impact the balance sheet only. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">      At June 30, 2010 and September 30, 2009, the Washington Gas Balance Sheets reflected receivables from associated companies of $1.3 million and $10.4 million, respectively. At June 30, 2010 and September 30, 2009, the Washington Gas Balance Sheets reflected payables to associated companies of $19.0 million and $11.4 million, respectively, related to the activities described above. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">      Additionally, 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 WGEServices. Washington Gas records revenues for these balancing services pursuant to tariffs approved by the appropriate regulatory bodies. In conjunction with such services and the related sales and purchases of natural gas, Washington Gas charged WGEServices, an affiliated energy marketer, $4.2 million and $4.1 million for the three months ended June 30, 2010 and 2009, respectively. In the nine months ended June 30, 2010 and 2009, the charges were $20.2 million and $21.0 million, respectively. These related party amounts have been eliminated in the consolidated financial statements of WGL Holdings. </div> <div align="left" style="font-size: 10pt; margin-top: 6pt">      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. WGEServices has recognized an accounts receivable from Washington Gas in the amount of $4.3 million and $4.6 million at June 30, 2010 and September 30, 2009, respectively, related to an imbalance in gas volumes. Due to regulatory requirements, these receivables are not eliminated in the consolidated financial statements of WGL Holdings. </div> </div>  <!-- Begin Block Tagged Note false false false us-types:textBlockItemType textblock This element may be used for the entire related party transactions disclosure as a single block of text.
