performance solutions ' adjusted ebitda for 2017 increased 8 % on a reported and constant currency basis . the increase was primarily driven by growth of our assembly , industrial and electronic solutions businesses resulting in higher gross profits , as well as cost savings from integration synergies , partially offset by the impact of volume declines in our graphics solutions business . agricultural solutions ' adjusted ebitda for 2017 increased 5 % ( 6 % at constant currency ) . the constant currency increase was primarily driven by an increase from market expansion in europe and new product launches in asia and latin america , volume growth in higher-margin products and cost reduction initiatives in europe and latin america . these increases were partially offset by a change in our selling strategy of certain lower-margin businesses in west africa , and investments made in stg & a , as noted above . year ended december 31 , 2016 compared to year ended december 31 , 2015 net sales replace_table_token_15_th performance solutions ' net sales for 2016 increased by 121 % ( 123 % on a constant currency and 1 % on an organic basis ) compared to the prior period . the increase in organic net sales was driven by growth in global paste solder product demand in assembly solutions , share gains in industrial product offerings sold into the automotive supply chain in asia , specifically in china , and a recovery of product demand in electronic solutions in the second half of 2016. organic sales growth in these businesses was partially offset by under-performance in offshore solutions due to softness in the oil and gas end market as declines in oil prices resulted in reduced capital investment and project startup delays . the impact of oil prices was twofold : ( 1 ) reduced demand for offshore production control and drilling fluids , and ( 2 ) reduced demand for plating chemistry sold into the supply chain for onshore oil production rigs and stripping/cleaning chemistry utilized in polyethylene terephthalate recycling . agricultural solutions ' net sales for 2016 increased by 4 % ( 6 % on a constant currency and 3 % on an organic basis ) compared to the prior period . the increase in organic net sales was driven by volume growth in our insecticide and herbicide businesses in latin america and europe , our anti-malarial insecticides in africa , and our biosolutions business . the volume growth was primarily boosted by several new product launches and continued focus on promoting proprietary brands . these effects were partially offset by lower volumes in north america , mainly due to low commodity prices , declining farmer incomes and soft demand for crop protection products , as well as our continued integration efforts to reduce volumes related to low-margin products across geographic markets . additionally , although generic competition and low commodity prices led to some pricing pressure , overall agricultural solutions achieved an improvement in pricing driven primarily by latin america and europe . 53 gross profit replace_table_token_16_th performance solutions ' gross profit for 2016 increased by 100 % ( 103 % at constant currency and 1 % on an organic basis ) . the organic gross profit increase was driven by gross margin expansion resulting from lower raw material costs , some of which were achieved through synergies , as well as favorable product mix , partially offset by lower sales volume from offshore solutions . the most significant growth came from our higher-margin advanced electronics solutions and industrials solutions product lines , particularly in asia . agricultural solutions ' gross profit for 2016 increased by 21 % ( 23 % at constant currency and 19 % on an organic basis ) . the increase was largely a result of $ 58.0 million of inventory step-up amortization in 2015 which did not recur in 2016. the gross profit increase was also driven by a broad increase in sales volumes , including higher relative growth in our biosolutions products , which generate , on average , higher margins , as well as procurement savings , driven by our ongoing integration and synergy efforts . we continued to see favorable effects from improved procurement trends , product mix , the impact of our proprietary product portfolio , and growth in the niche markets in which we operate . selling , technical , general and administrative expense ( stg & a ) replace_table_token_17_th performance solutions ' stg & a for 2016 increased by 108 % ( 110 % at constant currency and 13 % on an organic basis ) . the organic increase was driven by charges associated with integration activities and higher debt refinancing costs . agricultural solutions ' stg & a for 2016 increased by 6 % ( 9 % at constant currency and 3 % on an organic basis ) . the increase was driven primarily by a modest increase due to price inflation related to wages in developing markets , investments in infrastructure in support of growth in the business , continued integration expenses , and higher costs associated with non-recourse factoring programs . the increase was partially offset by savings from headcount reductions associated with synergies achieved in our operations in africa and europe and a decline in restructuring expenses related to the acquisitions within this segment . corporate stg & a for 2016 decreased by 20 % on a reported , constant currency and organic basis . story_separator_special_tag the increase in working capital was due , in part , to the buildup of inventory in connection with performance solution 's facility rationalization initiatives , as well as increases due to stronger fourth quarter sales in our agricultural solutions business in 2017 , partially offset by the impact of a new factoring program in europe . investing activities net cash flows used in investing activities for 2017 totaled $ 92.6 million , compared to $ 74.7 million for 2016 . the increase was driven primarily by capital expenditures related to our performance solutions ' facility integration initiatives and agricultural solutions ' investments in products registration rights , which , combined , increased by $ 7.2 million over 2016 . the increase was also driven by higher restricted cash balances of $ 4.7 million . financing activities net cash flows used in financing activities for 2017 totaled $ 67.4 million , compared to $ 102 million for 2016 . the decrease was driven primarily by the settlement of our make-whole obligation in 2016 related to our series b convertible preferred stock with a cash payment of $ 460 million to the series b convertible preferred stockholders , offset , in part , by the september 2016 equity offering which raised net proceeds of $ 392 million . in addition , for 2017 , net payments on our various lines of credit , short-term debt facilities and overdraft facilities totaled $ 58.8 million , as compared to net draws totaling $ 54.0 million in 2016 . our decreased on-balance sheet factoring activity increased financing cash flows year-over-year by $ 40.6 million , as did the net change in our long-term debt balance , which impacted financing cash flows by $ 59.8 million . 58 year ended december 31 , 2016 compared to year ended december 31 , 2015 operating activities for 2016 , we generated cash flows from operating activities of $ 185 million , compared to $ 321 million in cash for 2015 . this year-over-year change was driven primarily by higher cash operating profits ( net loss adjusted for non-cash items ) , partially offset by an increased use of cash in working capital as well as higher interest and tax payments . the increase in working capital , largely due to accounts payable , was primarily due to the timing of the close of the arysta acquisition in february 2015 and the working capital seasonality in the agricultural solutions segment . typically , the segment 's working capital is a use of cash at the beginning of the year and a source of cash at the end of the year . investing activities net cash flows used in investing activities for 2016 totaled $ 74.7 million , compared to $ 4.26 billion for 2015 . during 2015 , we used net cash of $ 4.60 billion to fund the arysta , alent and omg acquisitions . additional acquisition-related activity during 2015 included a $ 600 million release of restricted cash , partially offset by a note in the amount of $ 125 million issued to an unrelated third-party and an unfavorable settlement of foreign exchange contracts for $ 73.7 million , which effectively increased the purchase price of alent . there was no significant , comparable acquisition-related activity during 2016. capital expenditures increased by approximately $ 8.4 million during 2016 compared to 2015 , primarily in support of operational expansion , and there was a $ 2.0 million decline in investments in , and renewals of , product registrations . financing activities net cash flows used in financing activities for 2016 totaled $ 102 million , compared to $ 4.00 billion of cash generated for 2015 . the primary sources of cash from financing activity during 2016 were proceeds from amendments no . 5 and 6 to our amended and restated credit agreement of $ 3.30 billion and the september 2016 equity offering of 48,787,878 shares of our common stock which raised net proceeds of $ 392 million . these proceeds were used for the refinancing of our term loans of $ 3.31 billion and for the settlement of our previously-disclosed make-whole obligation related to our series b convertible preferred stock with a cash payment of $ 460 million to the series b convertible preferred stock holders . the primary sources of cash from financing activity during 2015 were $ 3.92 billion from the extension of new term loans and the issuance of our senior notes , and $ 470 million as net proceeds from the june 2015 equity offering of 18,226,414 shares of our common stock , offset in part by $ 87.0 million of financing fees paid . these proceeds were used to fund our 2015 acquisition activity . additionally , for 2016 , we had net draws on our various lines of credit , short-term debt facilities , and overdraft facilities of $ 54.0 million , compared to net payments of $ 12.4 million in 2015. pension plans we maintain `` domestic pension plans , `` which consist of a non-contributory domestic defined benefit pension plan and a serp plan . these plans are closed to new participants and plan benefits associated with all current participants have
