Based on market comparisons, each officer position is assigned a target award expressed as a percentage of base salary. Targets for these officers range from 60% to 100%, including the Chief Executive Officer. Award amounts paid to each officer are determined as follows: (1) the executive's most recent year-end base salary is multiplied by an AIP target percentage to arrive at the target award;
(2) the overall performance payout percentage, which can range from 0% to 175%, is determined based on final results compared to threshold, target and maximum levels for each objective; (3) the target award is then multiplied by the performance payout percentage to arrive at the calculated award; and (4) the calculated award is then adjusted by an individual performance modifier (assessment of an individual executive's achievements for the year), which can range from 0% to 150%, to arrive at the final award.

Long-Term Incentive Plan

On February 6, 2013, the Organization and Compensation Committee of the Company's Board of Directors approved 2015 performance measures, weightings and metrics for executive officers under the DTE Energy Company 2006 Long Term Incentive Plan ("LTIP"). The LTIP, which was approved by our shareholders, rewards long-term growth and profitability by providing a vehicle through which officers, other key employees and outside directors may receive stock-based compensation. Stock-based compensation directly links individual performance with shareholder interests. Based on market comparisons, each officer position is assigned a target award expressed as a percentage of base salary. The target award may be modified by the Organization and Compensation Committee and is then delivered in the form of restricted stock, stock options and performance shares. Targets for these officers range from 135% to 340%, including the Chief Executive Officer.

Performance shares: Performance shares entitle the executive to receive a specified number of shares, or a cash payment equal to the fair market value of the shares, or a combination thereof, depending on the level of achievement of performance measures. The performance measurement period for the 2015 award is January 1, 2013 through December 31, 2015. Payments earned under the 2015 award can range from 0% to 200% of target, based upon achievement of performance measures. The two measures and weightings for Messrs. Anderson, Meador and Peterson are: (1) total shareholder return vs. total shareholder return of peer group companies (80%), and (2) ratio of funds from operations to debt (20%). The three measures and weightings for Mr. Kurmas are: (1) total shareholder return vs. total shareholder return of peer group companies (60%),

(2) ratio of funds from operations to debt (20%) and (3) DTE Electric 3 year average return on equity (20%). The five measures and weightings for Mr. Norcia are: (1) total shareholder return vs. total shareholder return of peer group companies (54%), (2) ratio of funds from operations to debt (17%), (3) DTE Gas 3 year average return on equity (14%), (4) GSP 3 year average net income (12%), and (5) GSP 3 year average return on invested capital (3%).
