Please answer the given financial question based on the context.
Context: management 2019s discussion and analysis of increased volumes in our performance and applied coatings , optical and specialty materials and glass reportable business segments was offset by volume declines in the commodity chemicals reportable business segment . the volume decline in the commodity chemicals reportable business segment was due in part to lost sales resulting from the impact of hurricane rita , as discussed below . cost of sales as a percentage of sales increased to 63.5% ( 63.5 % ) as compared to 63.1% ( 63.1 % ) in 2004 . inflation , including higher coatings raw material costs and higher energy costs in our commodity chemicals and glass reportable business segments increased our cost of sales . selling , general and administrative expense declined slightly as a percentage of sales to 17.4% ( 17.4 % ) despite increasing by $ 56 million in 2005 . these costs increased primarily due to increased advertising in our optical products operating segment and higher expenses due to store expansions in our architectural coatings operating segment . interest expense declined $ 9 million in 2005 , reflecting the year over year reduction in the outstanding debt balance of $ 80 million . other charges increased $ 284 million in 2005 primarily due to pretax charges of $ 132 million related to the marvin legal settlement , net of $ 18 million in insurance recoveries , $ 61 million for the federal glass class action antitrust legal settlement , $ 34 million of direct costs related to the impact of hurricanes rita and katrina , $ 27 million for an asset impairment charge in our fine chemicals operating segment , $ 19 million for debt refinancing costs and an increase of $ 12 million for environmental remediation costs . net income and earnings per share 2013 assuming dilution for 2005 were $ 596 million and $ 3.49 respectively , compared to $ 683 million and $ 3.95 , respectively , for 2004 . net income in 2005 included aftertax charges of $ 117 million , or 68 cents a share , for legal settlements net of insurance ; $ 21 million , or 12 cents a share for direct costs related to the impact of hurricanes katrina and rita ; $ 17 million , or 10 cents a share related to an asset impairment charge related to our fine chemicals business ; and $ 12 million , or 7 cents a share , for debt refinancing costs . the legal settlements net of insurance include aftertax charges of $ 80 million for the marvin legal settlement , net of insurance recoveries , and $ 37 million for the impact of the federal glass class action antitrust legal settlement . net income for 2005 and 2004 included an aftertax charge of $ 13 million , or 8 cents a share , and $ 19 million , or 11 cents a share , respectively , to reflect the net increase in the current value of the company 2019s obligation relating to asbestos claims under the ppg settlement arrangement . results of reportable business segments net sales segment income ( millions ) 2005 2004 2005 2004 industrial coatings $ 2921 $ 2818 $ 284 $ 338 performance and applied coatings 2668 2478 464 451 optical and specialty materials 867 805 158 186 .

sales of industrial coatings increased $ 103 million or 4% ( 4 % ) in 2005 . sales increased 2% ( 2 % ) due to higher selling prices in our industrial and packaging coatings businesses and 2% ( 2 % ) due to the positive effects of foreign currency translation . volume was flat year over year as increased volume in automotive coatings was offset by lower volume in industrial and packaging coatings . segment income decreased $ 54 million in 2005 . the decrease in segment income was due to the adverse impact of inflation , including raw materials costs increases of about $ 170 million , which more than offset the benefits of higher selling prices , improved sales margin mix , formula cost reductions , lower manufacturing costs and higher other income . performance and applied coatings sales increased $ 190 million or 8% ( 8 % ) in 2005 . sales increased 4% ( 4 % ) due to higher selling prices in all three operating segments , 3% ( 3 % ) due to increased volumes as increases in our aerospace and architectural coatings businesses exceeded volume declines in automotive refinish , and 1% ( 1 % ) due to the positive effects of foreign currency translation . performance and applied coatings segment income increased $ 13 million in 2005 . segment income increased due to the impact of increased sales volumes described above and higher other income , which combined to offset the negative impacts of higher overhead costs to support the growth in these businesses , particularly in the architectural coatings business , and higher manufacturing costs . the impact of higher selling prices fully offset the adverse impact of inflation , including raw materials cost increases of about $ 75 million . optical and specialty materials sales increased $ 62 million or 8% ( 8 % ) . sales increased 8% ( 8 % ) due to higher sales volumes in our optical products and silica businesses , which offset lower sales volumes in our fine chemicals business . sales increased 1% ( 1 % ) due to an acquisition in our optical products business and decreased 1% ( 1 % ) due to lower pricing . segment income decreased $ 28 million . the primary factor decreasing segment income was the $ 27 million impairment charge related to our fine chemicals business . the impact of higher sales volumes described above was offset by higher inflation , including increased energy costs ; lower selling prices ; increased overhead costs in our optical products business to support growth 24 2006 ppg annual report and form 10-k 4282_txt .
