Segment and Geographic Information We have four operating segments: Wholesale  North America, Europe, Specialty and Self Service. Our Wholesale  North America and Self Service operating segments are aggregated into one reportable segment, North America, because they possess similar economic characteristics and have common products and services, customers, and methods of distribution. Our reportable segments are organized based on a combination of geographic areas served and type of product lines offered. The reportable segments are managed separately as each business serves different customers (i.e. geographic in the case of North America and Europe and product type in the case of Specialty) and is affected by different economic conditions. Therefore, we present three reportable segments: North America, Europe and Specialty. The following tables present our financial performance by reportable segment for the periods indicated (in thousands): North America Europe Specialty Eliminations Consolidated Year Ended December 31, 2018 Revenue: Third Party $ 5,181,964 $ 5,221,754 $ 1,472,956 $  $ 11,876,674 Intersegment 645  4,724 (5,369 )  Total segment revenue $ 5,182,609 $ 5,221,754 $ 1,477,680 $ (5,369 ) $ 11,876,674 Segment EBITDA $ 660,153 $ 422,721 $ 168,525 $  $ 1,251,399 Depreciation and amortization (1) 87,348 178,473 28,256  294,077 Year Ended December 31, 2017 Revenue: Third Party $ 4,798,901 $ 3,636,811 $ 1,301,197 $  $ 9,736,909 Intersegment 750  4,319 (5,069 )  Total segment revenue $ 4,799,651 $ 3,636,811 $ 1,305,516 $ (5,069 ) $ 9,736,909 Segment EBITDA $ 655,275 $ 319,156 $ 142,159 $  $ 1,116,590 Depreciation and amortization (1) 86,303 120,805 23,095  230,203 Year Ended December 31, 2016 Revenue: Third Party $ 4,443,886 $ 2,920,470 $ 1,219,675 $  $ 8,584,031 Intersegment 739  4,048 (4,787 )  Total segment revenue $ 4,444,625 $ 2,920,470 $ 1,223,723 $ (4,787 ) $ 8,584,031 Segment EBITDA $ 589,945 $ 283,608 $ 131,427 $  $ 1,004,980 Depreciation and amortization (1) 80,923 94,979 22,432  198,334 (1) Amounts presented include depreciation and amortization expense recorded within cost of goods sold. The key measure of segment profit or loss reviewed by our chief operating decision maker, who is our Chief Executive Officer, is Segment EBITDA. Segment EBITDA includes revenue and expenses that are controllable by the segment. Corporate general and administrative expenses are allocated to the segments based on usage, with shared expenses apportioned based on the segment's percentage of consolidated revenue. We calculate Segment EBITDA as EBITDA excluding restructuring and acquisition related expenses, change in fair value of contingent consideration liabilities, other gains and losses related to acquisitions, equity method investments, or divestitures, equity in losses and earnings of unconsolidated subsidiaries and impairment of goodwill. EBITDA, which is the basis for Segment EBITDA, is calculated as net income, less net income (loss) attributable to noncontrolling interest, excluding discontinued operations, depreciation, amortization, interest (which includes loss on debt extinguishment) and income tax expense. The table below provides a reconciliation of Net Income to Segment EBITDA (in thousands): Year Ended December 31, 2018 2017 2016 Net income $ 483,168 $ 530,228 $ 463,975 Less: net income (loss) attributable to noncontrolling interest 3,050 (3,516 )  Net income attributable to LKQ stockholders 480,118 533,744 463,975 Subtract: Net (loss) income from discontinued operations (4,397 ) (6,746 ) 7,852 Net income from continuing operations attributable to LKQ stockholders 484,515 540,490 456,123 Add: Depreciation and amortization 274,213 219,546 191,433 Depreciation and amortization - cost of goods sold 19,864 10,657 6,901 Interest expense, net of interest income 144,536 100,620 87,682 Loss on debt extinguishment 1,350 456 26,650 Provision for income taxes 191,395 235,560 220,566 EBITDA 1,115,873 1,107,329 989,355 Subtract: Equity in (losses) earnings of unconsolidated subsidiaries (1) (64,471 ) 5,907 (592 ) Fair value loss on Mekonomen derivative instrument (1) (5,168 )   Gains on foreign exchange contracts - acquisition related (2)   18,342 Gains on bargain purchases (3) 2,418 3,870 8,207 Add: Restructuring and acquisition related expenses (4) 32,428 19,672 37,762 Inventory step-up adjustment - acquisition related 403 3,584 3,614 Impairment of goodwill (1) 33,244   Impairment of net assets held for sale 2,438   Change in fair value of contingent consideration liabilities (208 ) (4,218 ) 206 Segment EBITDA $ 1,251,399 $ 1,116,590 $ 1,004,980 (1) See Note 4, "Summary of Significant Accounting Policies ," for further information.
