Total company EBITDA for the second quarter, excluding special items, was $299 million in 2020 and $376 million in 2019.
Second quarter net income included special items expenses of $0.79 per share related primarily to the impairment of goodwill associated with our paper segment.
Excluding the special items that we mentioned, the $0.66 per share decrease in second quarter 2020 earnings compared to the second quarter of 2019 was driven primarily by lower prices and mix in our packaging segment of $0.66 and paper segment $0.05, lower volumes in our paper segment, $0.40 and higher depreciation expense, $0.04.
These items were partially offset by lower operating costs of $0.33, primarily in the areas of labor and fringes, repairs, materials and supplies and several fixed cost areas.
We also had lower annual outage expenses of $0.10, lower converting costs, $0.03, lower freight expenses, $0.02 and other costs, $0.01.
EBITDA, excluding special items in the second quarter of 2020 of $313 million with sales of $1.4 billion resulted in a margin of 22% versus last year's EBITDA of $349 million and sales of $1.5 billion or 23% margin.

Outside sales volume of containerboard was about 10,000 tons below last year's second quarter and 23,000 tons below the first quarter of 2020, and as we ran our containerboard system to demand, supplied the record needs of our box plants and positioned our inventory for even higher demand during an expected stronger third quarter.
