In addition, operating income before the effect of special items is a component of Avient’s annual and long-term employee incentive plans and is used in debt covenant computations. Senior management believes the measures described above are useful to investors because they allow for comparison to Avient's performance in prior periods without the effect of items that, by their nature, tend to obscure Avient's operating results due to the potential variability across periods based on timing, frequency and magnitude. A reconciliation of these measures to their most directly comparable GAAP measures is provided in the tables below. 1 Reconciliation of EBITDA by Segment Three Months Ended December 31, Year Ended 2020年12月31日 2019 2020 2019 Sales: Color, Additives and Inks $ 525.8 $ 226.7 $ 1,502.9 $ 1,003.8 Specialty Engineered Materials 190.6 177.5 708.8 745.7 Distribution 305.1 272.4 1,110.3 1,192.2 Corporate and eliminations (24.5) (18.0) (79.9) (79.0) Sales $ 997.0 $ 658.6 $ 3,242.1 $ 2,862.7 Operating income: Color, Additives and Inks $ 57.5 $ 27.2 $ 180.8 $ 147.4 Specialty Engineered Materials 30.4 18.8 94.4 83.7 Distribution 18.0 17.0 69.5 75.4 Corporate and eliminations (40.9) (42.5) (155.4) (149.7) Operating Income $ 65.0 $ 20.5 $ 189.3 $ 156.8 Items Below Operating Income in Corporate: Other income, net $ 11.7 $ 10.7 $ 24.3 $ 12.1 Depreciation & amortization: Color, Additives and Inks $ 27.3 $ 10.7 $ 75.1 $ 42.7 Specialty Engineered Materials 7.4 7.0 30.0 29.5 Distribution 0.3 0.1 0.7 0.5 Corporate and eliminations 2.8 1.0 9.3 5.4 Depreciation & Amortization $ 37.8 $ 18.8 $ 115.1 $ 78.1 EBITDA: Color, Additives and Inks $ 84.8 $ 37.9 $ 255.9 $ 190.1 Specialty Engineered Materials 37.8 25.8 124.4 113.2 Distribution 18.3 17.1 70.2 75.9 Corporate and eliminations (26.4) (30.8) (121.8) (132.2) EBITDA $ 114.5 $ 50.0 $ 328.7 $ 247.0 EBITDA as a % of sales: Color, Additives and Inks 16.1 % 16.7 % 17.0 % 18.9 % Specialty Engineered Materials 19.8 % 14.5 % 17.6 % 15.2 % Distribution 6.0 % 6.3 % 6.3 % 6.4 % Corporate and eliminations nm nm nm nm Total Company 11.5 % 7.6 % 10.1 % 8.6 % nm -
