Other Events.

On April 2, 2012, the Connecticut Public Utility Regulatory Authority (“PURA”) issued a final decision (the “Final Decision”) in Docket No. 12-01-07, the proceeding to consider the joint application for approval of the merger transaction involving NSTAR and Northeast Utilities (“NU”). The Final Decision confirmed PURA’s draft decision issued on March 26, 2012, described in the Current Report on Form 8-K filed by NSTAR with the Securities and Exchange Commission (“SEC”) on March 27, 2012.

A copy of the Final Decision is available at the following link:

NSTAR and NU and are awaiting approval from the Massachusetts Department of Public Utilities (“DPU”). On February 15, 2012, NSTAR and NU reached comprehensive merger-related settlement agreements with both the Massachusetts Attorney General and the Massachusetts Department of Energy Resources agreeing to certain conditions with respect to the merger, which are subject to DPU approval and have been requested by the parties to be approved on April 4, 2012. If the DPU issues an acceptable decision on April 4, 2012, NSTAR expects the merger will be consummated by April 16, 2012.

For further information regarding the pending NSTAR-NU merger, please refer to the Registration Statement on Form S-4 (Registration No. 333-170754) filed by NU with the SEC in connection with the merger; NSTAR’s Annual Report on Form 10-K for the year ended December 31, 2011 filed with the SEC on February 6, 2012 and NSTAR’s Current Reports on Form 8-K filed on February 15, 2012, March 7, 2012 and March 14, 2012.
