Tabular List, Table |  | Financial Performance Measures As described in more detail in “Compensation Discussion and Analysis,” the Company’s executive compensation program reflects a pay for performance philosophy. The metrics that the Company uses for both AIP and LTIP awards are selected to support achievement of our business strategy without encouraging excessive risk-taking. Pay for performance is one of the primary objectives of our compensation program. The most important financial measures used by the Company to link executive compensation actually paid to the Company’s NEOs, for the most recently completed fiscal year, to the Company’s performance are as follows:
• | TSR versus companies in the EEI Index
• | Adjusted EPS for Incentive Compensation
• | Adjusted NFOM Expense for Incentive Compensation
• | Three Year Cumulative Adjusted EPS
In addition, the Company considers additional non-financial measures, including those relating to safety, operations, customer experience, environmental factors, and employee culture and engagement. These measures are intended to support our short- and long-term strategic plans and align with the creation of shareholder value. See “Compensation Discussion and Analysis” for a description of these measures. |  |  |  |  |

- Definition The estimated measure of the percentage by which a share price is expected to fluctuate during a period. Volatility also may be defined as a probability-weighted measure of the dispersion of returns about the mean. The volatility of a share price is the standard deviation of the continuously compounded rates of return on the share over a specified period. That is the same as the standard deviation of the differences in the natural logarithms of the stock prices plus dividends, if any, over the period. + References Reference 1: http://www.xbrl.org/2003/role/disclosureRef -Topic 718 -SubTopic 10 -Name Accounting Standards Codification -Section 50 -Paragraph 2 -Subparagraph (f)(2)(ii) -Publisher FASB -URI https://asc.fasb.org/1943274/2147480429/718-10-50-2 + Details
