Management views adjusted (non-Generally Accepted Accounting Principles) earnings as a key measure of the Company's present operating financial performance and uses adjusted earnings for external communications with analysts and investors. Internally, the Company uses adjusted earnings to measure and assess performance. Adjustments could include items such as discontinued operations, asset sales, impairments, restructuring costs, business optimization initiative, major enterprise resource planning software implementations, changes in accounting principles, voluntary separation program, changes in federal and state 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. The adjusted earnings should be considered supplemental information to assist in understanding our business results, rather than as a substitute for reported earnings.
