Question: what is the percentual growth observed in the percentage of asset impairment costs concerning the restructuring and other charges costs during 2013 and 2014?
Evidence:
table_1: the asset impairments of 2015 is $ 335 ; the asset impairments of 2014 is $ 406 ; the asset impairments of 2013 is $ 116 ;
table_8: the restructuring and other charges of 2015 is $ 1195 ; the restructuring and other charges of 2014 is $ 1168 ; the restructuring and other charges of 2013 is $ 782 ;
Program: divide(116, 782), divide(406, 1168), subtract(#1, #0)
