Under this arrangement, BGE had invested $77.3 million at September 30, 2009 and $148.8 million at December 31, 2008.         BGE's Consolidated Balance Sheets include intercompany amounts related to BGE's purchases to meet its standard offer service obligation, BGE's gas purchases, BGE's charges to Constellation Energy and its nonregulated affiliates for certain services it provides them, Constellation Energy and its nonregulated affiliates' charges to BGE for certain services provided to BGE, and the participation of BGE's employees in the Constellation Energy defined benefit plans.         BGE will cease participation in the cash pool in accordance with the Maryland PSC's order approving our transaction with EDF.</td></tr></table> Related Party Transactions BGEIncome Statement BGE is obligated to provide market-based standard offer service to all of its electric customers for false false No definition available.
