this segment represents a portion of alcoa 2019s downstream operations and produces products that are used mostly in the aerospace ( commercial and defense ) , commercial transportation , and power generation end markets . such products include fastening systems ( titanium , steel , and nickel alloys ) and seamless rolled rings ( mostly nickel alloys ) ; and investment castings ( nickel super alloys , titanium , and aluminum ) , including airfoils and forged jet engine components ( e.g. , jet engine disks ) , all of which are sold directly to customers and through distributors . more than 70% ( 70 % ) of the third- party sales in this segment are from the aerospace end market . a small part of this segment also produces various forging and extrusion metal products for the oil and gas , industrial products , automotive , and land and sea defense end markets . seasonal decreases in sales are generally experienced in the third quarter of the year due to the european summer slowdown across all end markets . generally , the sales and costs and expenses of this segment are transacted in the local currency of the respective operations , which are mostly the u.s . dollar and the euro . in march 2015 , alcoa completed the acquisition of an aerospace castings company , tital , a privately held company with approximately 650 employees based in germany . tital produces aluminum and titanium investment casting products for the aerospace and defense end markets . in 2014 , tital generated sales of approximately $ 100 . the purpose of this acquisition is to capture increasing demand for advanced jet engine components made of titanium , establish titanium-casting capabilities in europe , and expand existing aluminum casting capacity . the operating results and assets and liabilities of tital were included within the engineered products and solutions segment since the date of acquisition . also in march 2015 , alcoa signed a definitive agreement to acquire rti international metals , inc . ( rti ) , a global supplier of titanium and specialty metal products and services for the commercial aerospace , defense , energy , and medical device end markets . on july 23 , 2015 , after satisfying all customary closing conditions and receiving the required regulatory and rti shareholder approvals , alcoa completed the acquisition of rti . the purpose of this acquisition is to expand alcoa 2019s range of titanium offerings and add advanced technologies and materials , primarily related to the aerospace end market . in 2014 , rti generated net sales of $ 794 and had approximately 2600 employees . alcoa estimates that rti will generate approximately $ 1200 in third-party sales by 2019 . in executing its integration plan for rti , alcoa expects to realize annual cost savings of approximately $ 100 by 2019 due to synergies derived from procurement and productivity improvements , leveraging alcoa 2019s global shared services , and driving profitable growth . the operating results and assets and liabilities of rti were included within the engineered products and solutions segment since the date of acquisition . on november 19 , 2014 , after satisfying all customary closing conditions and receiving the required regulatory approvals , alcoa completed the acquisition of firth rixson , a global leader in aerospace jet engine components . firth rixson manufactures rings , forgings , and metal products for the aerospace end market , as well as other markets requiring highly engineered material applications . the purpose of this acquisition is to strengthen alcoa 2019s aerospace business and position the company to capture additional aerospace growth with a broader range of high-growth , value- add jet engine components . this business generated sales of approximately $ 970 in 2014 and has 13 operating facilities in the united states , united kingdom , europe , and asia employing approximately 2400 people combined . in executing its integration plan for firth rixson , alcoa expects to realize annual cost savings of more than $ 100 by 2019 due to synergies derived from procurement and productivity improvements , optimizing internal metal supply , and leveraging alcoa 2019s global shared services . the operating results and assets and liabilities of firth rixson were included within the engineered products and solutions segment since the date of acquisition . third-party sales for the engineered products and solutions segment improved 27% ( 27 % ) in 2015 compared with 2014 , largely attributable to the third-party sales ( $ 1310 ) of three acquired businesses ( see above ) , primarily aerospace- related , and higher volumes in this segment 2019s organic businesses , mostly related to the aerospace end market . these positive impacts were slightly offset by unfavorable foreign currency movements , principally driven by a weaker euro. .
Question: what is the percentage of the three acquired businesses , that were responsible for the 27% ( 27 % ) improvement in third-party sales?


Answer: The answer is:0.24523
