Item 2.01.  Completion of Acquisition or Disposition of Assets

Effective January 1, 2007, NSTAR , the parent company of Boston Edison Company (Boston Edison), completed the transfer of the assets (consisting primarily of the utility distribution facilities, properties and other assets, rights, and franchises) and liabilities, consisting of the net assets of its wholly-owned electric subsidiaries, Commonwealth Electric Company (Commonwealth), Cambridge Electric Light Company (Cambridge) and Canal Electric Company (Canal) to Boston Edison.  The transfer of net assets was structured as a merger of Commonwealth, Cambridge and Canal into Boston Edison.  The transfer of net assets was made pursuant to NSTAR's Settlement Agreement of December 30, 2005 as approved by the Massachusetts Department of Telecommunications and Energy (MDTE).  The transfer of net assets was approved by the MDTE and by the Federal Energy Regulatory Commission.  In connection with the transaction, Boston Edison changed its corporate name to NSTAR Electric Company (NSTAR Electric).  In accordance with the Financial Accounting Standards Board, Statement of Financial Accounting Standards No. 141 "Business Combinations," the financial statements of Boston Edison (the combined entity) would report results of operations, cash flows and financial position for the period in which the transfer occurs as though the transfer had occurred at the beginning of the earliest period presented.  In connection with the merger, Boston Edison issued an aggregate of 25 of its Common Shares, par value $1.00 per share, to NSTAR in exchange for the net assets of such companies.  The exchange rate was determined and allocated based on the percentage of common equity of Commonwealth, Cambridge and Canal.  Following the transaction, NSTAR Electric (f.k.a. Boston Edison) will continue as a wholly-owned subsidiary of NSTAR.
