Non-GAAP Financial Measures Our reported results are presented in accordance with accounting principles generally accepted in the United States of America (“GAAP”). We also disclose Non-GAAP Adjusted Net Loss Attributable to Common Stockholders and Non-GAAP Adjusted Net Loss Attributable to Common Stockholders Per Share, each of which are non-GAAP financial measures. We believe these non-GAAP financial measures are useful to investors because they provide a meaningful supplement to the Company’s operating performance and period-over-period changes without regard to certain potential distortions or certain non-cash items.

Non-GAAP Adjusted Net Loss Attributable to Common Stockholders and Non-GAAP Adjusted Net Loss Attributable to Common Stockholders Per Share do not represent cash generated from operating activities and are not necessarily indicative of cash available to fund cash requirements. Accordingly, they should not be considered alternatives to net loss as a performance measure or cash flows from operating activities as reported on our statement of cash flows as a liquidity measure and should be considered in addition to, and not in lieu of, GAAP financial measures. To derive Non-GAAP Adjusted Net Loss Attributable to Common Stockholders, GAAP net loss attributable to common stockholders is adjusted to exclude depreciation and amortization, as well as gains and losses from the sale of assets, gains or losses on extinguishment of debt, and provisions for impairment, and these adjustments include the pro rata share of such adjustments of unconsolidated subsidiaries. Additionally, adjustments are made for non-cash revenues and expenses such as straight-line rental revenue and expenses, amortization of above- and below-market lease related intangibles, and non-cash compensation; other non-recurring items such as termination fees, leadership transition costs, corporate restructuring costs, and legal settlements; and certain capitalized items such as capitalized interest. Please see the reconciliation table provided in this press release for a reconciliation of Non-GAAP Adjusted Net Loss Attributable to Common Stockholders and Non-GAAP Adjusted Net Loss Attributable to Common Stockholders Per Share to the most directly comparable GAAP measure of net loss.
