In addition, the Company has presented adjusted net income and adjusted net income per diluted common share as a measure of financial and operating performance. Adjusted net income is a measure that is not defined by U.S. GAAP and should not be considered a substitute for net income, income from operations or cash flow from operations, as determined in accordance with U.S. GAAP. Adjusted net income is a measure of our operating and financial performance used by management to focus on consolidated financial and operating performance exclusive of income and expenses that relate to non-routine or significant non-cash items of the business.We define adjusted net income (loss) as net income before non-cash interest expense related to amortization of deferred financing fees, terminations and modifications of derivative instruments, losses on retirement of debt, fair value adjustments on derivative instruments, loss on swap terminations, and write-offs of goodwill. We use adjusted net income to assess our consolidated financial and operating performance, and we believe this non-GAAP measure is helpful to management and investors in identifying trends in our performance. This measure helps management make decisions which are expected to facilitate meeting current financial goals as well as achieve optimal financial performance. Adjusted net income provides us with a measure of financial performance of the business based on operational factors including the profitability of assets on an economic basis net of operating expenses and the capital costs of the business on a consistent basis as it removes the impact of certain non-routine and non-cash items from our operating results. Adjusted net income is a key metric used by senior management and our board of directors to review the consolidated financial performance of the business. Adjusted net income is a non-GAAP measure, and, as such, a reconciliation of adjusted net income to net income is provided below.
