27 27 GAAP Reconciliation CMS Energy provides historical financial results on both a reported (GAAP) and adjusted (non - GAAP) basis and provides forward - lo oking guidance on an adjusted basis. During an oral presentation, references to “earnings” are on an adjusted basis. All references to net income ref er to net income available to common stockholders and references to earnings per share are on a diluted basis. Adjustments could include items such as disc ont inued operations, asset sales, impairments, restructuring costs, business optimization initiative, changes in accounting principles, voluntary separation pr ogr am, changes in federal tax policy, regulatory items from prior years, unrealized gains or losses from mark - to - market adjustments, recognized in net income related to NorthStar Clean Energy’s interest expense, or other items. Management views adjusted earnings as a key measure of the company’s present operating fina nci al performance and uses adjusted earnings for external communications with analysts and investors. Internally, the company uses adjusted earnings to mea sure and assess performance. Because the company is not able to estimate the impact of specific line items, which have the potential to significantly impa ct, favorably or unfavorably, the company's reported earnings in future periods, the company is not providing reported earnings guidance nor is it providing a rec onciliation for the comparable future period earnings. The adjusted earnings should be considered supplemental information to assist in understanding our bu sin ess results, rather than as a substitute for the reported earnings.
