We define Total Adjusted EBITDA as our income (loss) from continuing operations, excluding the impact of income tax expense (benefit), depreciation, depletion and amortization, net interest expense, loss on extinguishment of debt, derivative loss, non-cash change in revaluation of contingent consideration, impairment of goodwill and other assets, hurricane-related losses, quarry dredge costs for specific event, purchase accounting adjustments for inventory, certain foreign currency losses resulting from Polaris acquisition, non-cash stock compensation expense, acquisition-related professional fees, and officer transition expenses. Acquisition-related professional fees consists of fees and expenses for accountants, lawyers and other professionals incurred during the negotiation and closing of strategic acquisitions and does not include fees or expenses associated with post-closing integration of strategic acquisitions. We define Total Adjusted EBITDA Margin as the amount determined by dividing Total Adjusted EBITDA by total revenue. We have included Total Adjusted EBITDA and Total Adjusted EBITDA Margin herein because they are widely used by investors for valuation and comparing our financial performance with the performance of other building material companies. We also use Total Adjusted EBITDA and Total Adjusted EBITDA Margin to monitor and compare the financial performance of our operations. Total Adjusted EBITDA does not give effect to the cash we must use to service our debt or pay our income taxes and thus does not reflect the funds actually available for capital expenditures. In addition, our presentation of Total Adjusted EBITDA may not be comparable to similarly titled measures other companies report. Total Adjusted EBITDA and Total Adjusted EBITDA Margin are not intended to be used as an alternative to any measure of our performance in accordance with GAAP. The following table reconciles Total Adjusted EBITDA to the most directly comparable GAAP financial measure, which is income (loss) from continuing operations (in thousands). Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, our reported operating results or cash flow from operations or any other measure of performance prepared in accordance with GAAP.
