transition to our new facility in gersthofen , germany . in 2015 , we completed our transition to our new facility in gersthofen , germany which has resulted in approximately doubling our available facility space and has substantially increased our production capacity of indirect printing machines and psc operations . this transition has also resulted in a full consolidation of our german production , research and development , sales and marketing and administrative teams under one combined facility . expansion of our north huntingdon , pa facility . in march 2015 , we completed our expansion of our north huntingdon , pa facility which has resulted in approximately doubling our available psc production space for this facility and has also expanded our available space for research and development activities . 32 debut of the exerial 3d printing system and delivery of the initial production units . in june 2015 , we debuted the exerial machine platform at the gifa international foundry trade fair in dusseldorf , germany . the exerial is unique compared to our other indirect printi ng systems in that it contains multiple industrial stations that allow for continuous production and simultaneous processing . the exerial is distinctly equipped with two build boxes , each 1.5 times larger than the single build box in our next largest model , the s-max . notably , the exerial system offers a total build platform of 3,168 liters and is expected to be capable of printing output rates nearly four times faster than the s-max . the exerial utilizes a new recoater system , multiple printheads and autom ation controls . as part of the development of the exerial , we have filed six patents related to machine design elements . we shipped our initial production units in june 2015. qualification of water wash-out tooling process for industrial 3d printing applications . in july 2015 , we announced the qualification of a new application for our additive manufacturing process , water wash-out tooling , designed to aid in the development of manufacturing and composite tooling . intended for the production of hollow parts , typical of mandrel or clamshell molding , our water wash-out tooling process involves the 3d printing of a core in sand , ceramics or carbon , applying a composite lay-up and curing . the final core is then washed out with only the structural composite part remaining . water wash-out tooling is ideal for printing mandrels for filament winding , tape placement or hand lay-up ; plugs and source tools ; styling and design models ; hollow or trapped shape fabrication ; and one-off parts for part validation . opening of the exone dream center . in july 2015 , we announced the opening of our new state-of-the-art design and re-engineering for additive manufacturing ( “ dream ” ) center located in our north huntingdon , pa facility . the dream center has been strategically developed as a physical and virtual site for collaboration with customers to explore and incorporate the benefits of our binder jetting technology . by providing global access to our creative technical expertise and offering the most advanced software currently available , the center will enable customers to create designs of metal components which maximize the benefits of additive manufacturing . opening of our psc in sweden . in august 2015 , we announced the opening of our ninth psc in jönköping , sweden in collaboration with swerea , the swedish research institute for industrial renewal and sustainable growth . swerea has research specialists who are leaders in the development of new technologies , methods and products for direct application in industry , with 3d printing being an area of focus . establishing our latest psc in this facility creates a cost effective opportunity for our introduction of binder jetting technologies to a market that is focused on the benefits of additive manufacturing for industrial applications . introduction of exone cold hardening phenolic binder . in september 2015 , we announced the expansion of the available suite of our binders to include exone cold hardening phenolic , or chp . phenolic binders , which we originally introduced in july 2013 , are generally used in connection with ceramic sands to produce 3d printed molds and cores that provide the benefit of high heat alloy casting , higher internal strength and higher quality , on the basis of reduced expansion of the mold or core . chp accelerates the 3d printing process by eliminating the infrared heating lamp that is utilized in the printing process with traditional phenolic binders . in addition , additional curing and drying processes , which previously required the use of an industrial microwave , may be achieved through use of a conventional air oven typically maintained by most industrial manufacturers . our initial introduction of chp is through delivery to customers of benchmark and production parts printed in our gersthofen , germany psc . we are in the process of optimizing our indirect printing machine platforms for utilization of chp with an availability date targeted in 2016. at market issuance offering . in january 2016 , we announced our entry into our atm with fbr and mlv pursuant to which fbr and mlv will act as distribution agents in the sale of up to $ 50,000 in the aggregate of exone common equity in “ at the market offerings ” as defined in rule 415 under the securities act . through march 22 , 2016 , we sold 91,940 shares under the atm at a weighted average selling price of approximately $ 9.17 per share resulting in gross proceeds of approximately $ 843. net proceeds to us from the sale of shares under the atm during this time period were approximately $ 595 ( after deducting offering costs of approximately $ 248 ) . registered direct offering to a related party . story_separator_special_tag selling , general and administrative expenses for 2014 were $ 24,029 compared with selling , general and administrative expenses of $ 16,119 for 2013 , an increase of $ 7,910 , or 49.1 % . this increase was principally due to ( i ) personnel costs associated with an increased headcount ( including salaries , related benefits , travel expenses and equity-based compensation ) , ( ii ) an increase in provisions for bad debts as a result of certain receivables experiencing deteriorating credit quality based on either customer-specific or macroeconomic factors , ( iii ) other growth-related expenses ( consulting and professional fees ) , ( iv ) higher selling expenses ( including higher sales commissions expense and increased trade show expenses ) , and ( v ) the impact of the mam and mwt acquisitions ( acquired in march 2014 ) , principally amortization of identified intangible assets . impairment during the quarter ended september 30 , 2015 , as a result of the significant decline in our market capitalization and continued operating losses and cash flow deficiencies , we identified a triggering event requiring both ( i ) a test for the recoverability of long-lived assets held for use at the asset group level and ( ii ) a test for impairment of goodwill at the reporting unit level . assessing the recoverability of long-lived assets held for use and goodwill requires significant judgments and estimates by our management . for purposes of testing long-lived assets for recoverability , we operate as three separate asset groups : united states , europe and japan . in assessing the recoverability of long-lived assets held for use , we determined the carrying amount of long-lived assets held for use to be in excess of the estimated future undiscounted net cash flows of the related assets . we proceeded to determination of the fair value of our long-lived assets held for use , principally through use of the market approach . our use of the market approach included consideration of market transactions for comparable assets . our management concluded that the fair value of long-lived assets held for use exceeded their carrying value and as such no impairment loss was recorded . we subsequently performed an impairment test for goodwill . for purposes of testing goodwill for impairment , we operate as a singular reporting unit . in assessing goodwill for impairment , we compared the fair value of our reporting unit to its carrying value . we determined the fair value of our reporting unit through a combination of the market approach and income approach . our use of the market approach included consideration of our market capitalization along with consideration of other factors that could influence the use of market capitalization as a fair value estimate , including premiums or discounts to be applied based on both market and entity-specific data . our use of the income approach included consideration of present value techniques , principally the use of a discounted cash flow model . in performing the impairment test for goodwill , we determined the carrying amount of goodwill to be in excess of the implied fair value of goodwill . as a result , we recognized an impairment loss of approximately $ 4,419 associated with goodwill during the quarter ended september 30 , 2015. during the quarter ended december 31 , 2015 , as a result of continued operating losses and cash flow deficiencies , we identified a triggering event requiring a test for the recoverability of long-lived assets held for use at the asset group level . we conducted a similar recoverability test to the test further described above at the asset group level . our management concluded that the fair value of long-lived assets held for use exceeded their carrying value and as such no impairment loss was recorded . a significant decrease in the market price of a long-lived asset , adverse change in the use or condition of a long-lived asset , adverse change in the business climate or legal or regulatory factors impacting a long-lived asset and continued operating losses and cash flow deficiencies associated with a long-lived asset , among other indicators , could cause a future assessment to be performed which may result in an impairment of our long-lived assets held for use , resulting in a material adverse effect on our financial position and results of operations . 37 interest expense interest expense for 2015 was $ 152 compared with interest expense of $ 144 in 2014 , an increase of $ 8 , or 5.6 % . this increase was due principally to the commitment fee on the unused portion of our revolving credit facility ( added in october 2015 ) , partially offset by lower average outstanding debt balance for 2015 for all other instruments as compared to 2014. interest expense for 2014 was $ 144 compared with interest expense of $ 372 in 2013 , a decrease of $ 228 , or 61.3 % . this decrease was due principally to a lower average outstanding debt balance for 2014 , as compared to 2013 , mostly due to ( i ) the retirement of the demand note payable to a member in february 2013 and ( ii ) the settlement of debt held by variable interest entities in connection with our acquisition of certain related assets of those entities in march 2013. other expense ( income ) — net other expense ( income ) — net for 2015 was ( $ 45 ) compared with other expense ( income ) — net of ( $ 210 ) for 2014 and other expense ( income ) — net of ( $ 98 ) for 2013. amounts for all periods consist principally of interest income on cash and cash equivalent balances and other financing activity benefits .
