3 TSR is calculated by dividing the sum of the cumulative amount of dividends for the measurement period (assuming dividend reinvestment) and the difference between our stock price at the end and the beginning of the measurement period by our stock price at the beginning of the measurement period.

4 Represents the weighted peer group TSR, weighted according to the respective companies' stock market capitalization at the beginning of each period for which a return is indicated. The peer group used is the EEI Utilities Index.

5 The dollar amounts reported represent the amount of net income reflected in the company's audited financial statements for the applicable year.

6 The company selected measure is CEPS, or cumulative earnings per share, which represents a key measure of performance for the benefit of shareholders aligning executive officers' management efforts to enhance revenue and contain costs with shareholders' performance objectives.
