Actual results may differ from these estimates under different assumptions or conditions. To the extent that actual results differ from management's judgments and estimates, there could be a material adverse effect on the Company. On a continuous basis, the Company evaluates its estimates, including, but not limited to, those estimates related to its allowance for doubtful accounts, inventory reserves, and valuation allowance for the deferred tax assets relating to its NOLs and commitments and contingencies. With respect to accounts receivable, the Company estimates the necessary allowance for doubtful accounts based on both historical and anticipated trends of payment history and the ability of the customer to fulfill its obligations. For inventory, the Company evaluates both current and anticipated sales prices of its products to determine if a write down of inventory to net realizable value is necessary. In determining the Company’s valuation allowance for its deferred tax assets, the Company assesses its ability to generate taxable income in the future.</div> <div style="CLEAR:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;MARGIN: 0in 0in 0pt" align="justify"> </div> <div style="CLEAR:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;MARGIN: 0in 0in 0pt" align="justify"> <div style="CLEAR:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;MARGIN: 0in 0in 0pt" align="justify">The Company participates in an industry that is highly regulated, and changes in the regulations affecting our business could affect our operating results. Currently the Company purchases virgin hydrochlorofluorocarbon (“HCFC”) and hydrofluorocarbon (“HFC”) refrigerants and reclaimable, primarily HCFC, HFC and chlorofluorocarbon (“CFC”), refrigerants from suppliers and its customers. Effective January 1, 1996, the Clean Air Act (the “Act”) prohibited the production of virgin CFC refrigerants and limited the production of virgin HCFC refrigerants. Effective January 2004, the Act further limited the production of virgin HCFC refrigerants and federal regulations were enacted which established production and consumption allowances for HCFC refrigerants which imposed limitations on the importation of certain virgin HCFC refrigerants. Under the Act, production of certain virgin HCFC refrigerants is scheduled to be phased out during the period 2010 through 2020, and production of all virgin HCFC refrigerants is scheduled to be phased out by 2030. In April 2013, the Environmental Protection Agency (“EPA”) published a final rule providing for the production or importation of <font style="FONT-FAMILY: 'Times New Roman','serif'; FONT-SIZE: 10pt">63</font> million and <font style="FONT-FAMILY: 'Times New Roman','serif'; FONT-SIZE: 10pt">51</font> million pounds of HCFC-22 in 2013 and 2014, respectively. In October 2014, the EPA published a final rule providing further reductions in the production and consumption allowances for virgin HCFC refrigerants for the years 2015 through 2019 (the “Final Rule”). In the Final Rule, the EPA has established a linear draw down for the production or importation of virgin HCFC-22 that started at approximately 22 million pounds in 2015 and reduces by approximately 4.5 million pounds each year and ends at zero in 2020.</div>  </div> <div style="CLEAR:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;MARGIN: 0in 0in 0pt" align="justify">To the extent that the Company is unable to source sufficient quantities of refrigerants or is unable to obtain refrigerants on commercially reasonable terms or experiences a decline in demand and/or price for refrigerants sold by the Company, the Company could realize reductions in revenue from refrigerant sales, which could have a material adverse effect on its operating results and its financial position.</div> <div style="CLEAR:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;MARGIN: 0in 0in 0pt" align="justify"> </div> <div style="CLEAR:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;MARGIN: 0in 0in 0pt" align="justify">The Company is subject to various legal proceedings.
