Adjusted earnings per share exclude, as applicable, (1) a one- time reduction in income tax expense related to a revaluation of our deferred taxes as a result of the Tax Cuts and Jobs Act of 2017; (2) costs related to the acquisition of Integrys Energy Group; (3) the results of operations of Integrys and its subsidiaries; (4) the additional shares of WEC Energy Group common stock that were issued as part of the acquisition; (5) a non-cash charge related to the ICC’s disallowance of certain capital costs; and (6) estimated losses associated with the ICC disallowance related to its review of the 2016 Qualifying Infrastructure Plant (QIP) capital investments under the QIP rider. None of these items are indicative of WEC Energy Group’s operating performance. Therefore, WEC Energy Group believes that the presentation of adjusted earnings per share is relevant and useful to investors to understand the company’s operating performance. Management uses such measures internally to evaluate the company’s performance and manage its operations.
