F1 · derivative.exercise_price: These shares constitute equity compensation earned by Mr. May as an executive employee over the period 1997 - 2005, the receipt of which was deferred by Mr. May pursuant to the registrant's non-qualified deferred compensation plan. This equity compensation has been disclosed in the registrant's proxy statements and reported on previously filed Forms 4. The shares are being distributed in accordance with the terms of the plan, which requires timely distribution and receipt at the beginning of the first quarter following retirement, except as required by IRS 409A regulations. This line discloses the acquisition by conversion of the previously reported deferred equity compensation, in the form of common share stock equivalents (phantom shares), which had a total cost to the registrant and value at award to Mr. May of approximately $7.5 million. The distribution of shares had no further impact on compensation expense to the registrant. The value of such shares has increased substantially through stock price appreciation that took place during the term of Mr. May's leadership and also through the accumulation of additional shares through dividend reinvestment. Each stock equivalent phantom share was settled for and represented the economic equivalent of one Eversource common share.

F5 · shares: Represents the disposition by conversion of the same deferred stock equivalent phantom shares disclosed as acquired common shares in Table I. Each share represents the right to receive one Eversource common share upon a distribution event. Additional phantom shares are issued upon the automatic reinvestment of dividend-equivalents exempt from line item reporting under SEC Rule 16a-11.
