Notes to Financial Statements
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	1. Basis of Presentation The consolidated condensed financial statements included herein have been prepared by the Company (which may be referred to as we, us or our), without an audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“the Commission”). Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations, although the Company believes the disclosures which are made are adequate to make the information presented not misleading. Further, the consolidated condensed financial statements reflect, in the opinion of management, all adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position and results of operations as of and for the periods indicated. The results of operations for the six months ended June 30, 2016 are not necessarily indicative of results to be expected for the fiscal year ending December 31, 2016. The Company suggests that these consolidated condensed financial statements be read in conjunction with the consolidated financial statements and the notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2015. As disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015, the Company determined that the operations of its majority-owned Polish subsidiary, Perma-Fix Medical S.A. (“PF Medical”), which has not generated any revenues as it continues to be primarily in the research and development (“R&D”) stage, meet the definition of a reportable segment in accordance with Accounting Standards Codification (“ASC”) 280, “Segment Reporting.” Accordingly, as detailed on Note 10 – “Operating Segments,” all of the historical numbers presented in the consolidated financial statements have been recast to include the operations of PF Medical as a separate reportable segment (“Medical Segment”). Reclassification Certain prior year amounts have been reclassified to conform to the current year presentation.

Notes to Financial Statements
Significant Accounting Policies [Text Block]	2. Summary of Significant Accounting Policies Our accounting policies are as set forth in the notes to the December 31, 2015 consolidated financial statements referred to above. During the first quarter of 2016, all of the restricted cash previously held in escrow at December 31, 2015 was released. Such amount represented $35,000 held in escrow for our worker’s compensation policy with the remaining representing proceeds held in escrow resulting from stock subscription agreements executed in connection with the sale of common stock by PF Medical in previous years. Recently Adopted Accounting Standards In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-03, "Simplifying the Presentation of Debt Issuance Costs." ASU 2015-03 amends existing guidance to require the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of a deferred charge asset. It is effective for annual reporting periods beginning after December 15, 2015 (including interim reporting periods), but early adoption is permitted. The Company adopted ASU 2015-03 retroactively in the first quarter of 2016. The adoption of ASU 2015-03 did not have a material impact to the Company’s results of operations, cash flows or financial position . The adoption of ASU 2015-03 resulted in a decrease in prepaid and other assets of approximately $152,000, a decrease in current portion of long-term debt of $27,000, and a decrease in long-term debt, less current portion of $125,000 for the balances as of December 31, 2015 in the accompanying Consolidated Balance Sheets. Recently Issued Accounting Standards – Not Yet Adopted In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." ASU 2014-09 provides a single, comprehensive revenue recognition model for all contracts with customers. The amendments in ASU 2014-09 require a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. Subsequently, in August 2015, the FASB issued ASU No. 2015-14, "Revenue from Contracts with Customers (Topic 606) Deferral of the Effective Date," that deferred the effective date of ASU 2014-09 to annual reporting periods beginning after December 15, 2017 (including interim reporting periods within those periods). In March 2016, the FASB issued ASU 2016-08, "Revenue from Contracts with Customer (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net)," which clarifies the guidance in determining revenue recognition as principal versus agent. In April 2016, the FASB issued ASU 2016-10, "Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing," which provides guidance in accounting for immaterial performance obligations and shipping and handling. In May 2016, the FASB issued ASU 2016-12, "Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients," which provides clarification on assessing the collectability criterion, presentation of sales taxes, measurement date for non-cash consideration and completed contracts at transition. Early adoption is permitted for ASU 2014-09 and the related amendment to the original effective date of period beginning after December 15, 2016 (including interim reporting periods within those periods). The ASUs may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. The Company is still evaluating the potential impact of adopting this guidance on our financial statements. In August 2014, the FASB issued ASU No. 2014-15, “Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.” ASU 2014-15 requires management to assess an entity’s ability to continue as a going concern, and to provide related footnote disclosure in certain circumstances. The new standard will be effective for all entities in the first annual period ending after December 15, 2016. The Company is still evaluating the potential impact of adopting this guidance on our financial statements. In July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330): Simplifying the Measurement of Inventory.” ASU In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)”. Under ASU 2016-02, an entity will be required to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. For public companies, ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, and requires a modified retrospective adoption, with early adoption permitted. The Company is still evaluating the potential impact of adopting this guidance on our financial statements. In March 2016, the FASB issued ASU 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” ASU 2016-09 simplifies several aspects related to the accounting for share-based payment transactions, including the accounting for income taxes, statutory tax withholding requirements and classification on the statement of cash flows. ASU 2016-09 is effective for interim and annual periods beginning after December 15, 2016. The Company is still evaluating the potential impact of adopting this guidance on our financial statements.

Notes to Financial Statements
Property, Plant, and Equipment and Intangible Assets [Text Block]	3 East Tennessee Materials and Energy Corporation (“M&EC”) Facility During the second quarter of 2016, the Company’s M&EC subsidiary was notified by the lessor that the lease agreement which M&EC currently operates its Oak Ridge, Tennessee facility would not be renewed at the end of the current lease term ending January 21, 2018. In light of this event and our strategic review of operations within our Treatment Segment, the Company is proceeding with a plan to shut down its M&EC facility located in Oak Ridge, Tennessee at the end of the lease term. The Company will continue operations at the M&EC facility during the remaining term of the lease and will begin the process of transitioning waste shipments and operational capabilities to our other Treatment Segment facilities, subject to customer requirements and regulatory approvals. Simultaneously, the Company will begin required clean-up/maintenance procedures at M&EC’s Oak Ridge, Tennessee facility in accordance with M&EC’s Resource Conservation and Recovery Act (“RCRA”) permit requirements. As a result of this triggering event, the Company’s financial results were impacted by certain non-cash impairment losses, write-offs and accruals as described below. The Company performs its annual intangible test as of October 1 of each year. As permitted by ASC 350, “Intangibles-Goodwill and Others,” when an impairment indicator arises during an interim reporting period, the Company may recognize its best estimates of that impairment loss. The Company performed a discounted cash flow analysis prepared as of June 30, 2016 for M&EC’s intangible assets (permits), utilizing our best estimates of projected future cash flows. Based on this analysis, the Company concluded that potential impairment existed and subsequently determined that the permits for our M&EC subsidiary were fully impaired, resulting in an intangible impairment loss of approximately $8,288,000. The Company also wrote-off approximately $587,000 in fees previously incurred relating to emission performance testing certification requirement in order to meet state compliance mandate in connection with a certain M&EC equipment which was impaired (see below for discussion of impairment loss recorded for M&EC's tangible assets). Such amount had been previously included in “Prepaid and other assets” on the Consolidated Balance Sheets. M&EC will be required to complete certain clean-up/maintenance activities at its Oak Ridge, Tennessee facility pursuant to its RCRA permit. The extent and cost of these activities are determined by federal/state mandate requirements. The Company performed an analysis and related estimate of the cost to complete the RCRA portion of these activities and based on this analysis, the Company recorded an additional $1,626,000 in closure liabilities with the offset to capitalized asset retirement costs, as reported as a component of “Net Property and equipment” in the Consolidated Balance Sheet.” In accordance with ASC 360, “Property, Plant, and Equipment,” the Company also performed an updated financial valuation of M&EC’s long-lived tangible assets, inclusive of the capitalized asset retirement costs, for potential impairment. Based on our analysis using an undiscounted cash flow approach, the Company concluded that the carrying value of certain tangible assets (property and equipment) for M&EC was not recoverable and exceeded its fair value. Consequently, the Company recorded $1,816,000 in tangible asset impairment loss. The Company reevaluated the estimated useful lives of the remaining tangible assets and as a result of this analysis, reduced the current estimated useful lives of these assets ranging from 2 to 28 years to 1.6 years. Accordingly, the Company will depreciate the carrying value of M&EC’s remaining tangible assets of approximately $4,728,000 at June 30, 2016 over a period of approximately 1.6 years. During the first six months of 2016 and the corresponding period of 2015, M&EC’s revenues were approximately $2,755,000 and $4,361,000, respectively.

On May 15, 2016, the Company granted 50,000 incentive stock options (“ISOs”) from the Company’s 2010 Stock Option Plan to our newly named Executive Vice President. The ISOs granted were for a contractual term of six years with one-third yearly vesting over a three year period.

The Loan Agreement, as subsequently amended (“Amended Loan Agreement”), provided the Company with the following Credit Facility: (a) up to $12,000,000 revolving line of credit (“Revolving Credit”), subject to the amount of borrowings based on a percentage of eligible receivables (as defined) and (b) a term loan (“Term Loan”) of $16,000,000, which required monthly installments of approximately $190,000 (based on a seven-year amortization). Under the Amended Loan Agreement, the Company had the option of paying an annual rate of interest due on the Revolving Credit at prime plus 2% or London Inter Bank Offer Rate (“LIBOR”) plus 3% and the Term Loan at prime plus 2.5% or LIBOR plus 3.5%. On March 24, 2016, the Company entered into an amendment to the Amended Loan Agreement with PNC which provided, among other things, the following (the amendment, together with the Amended Loan Agreement is collectively known as the “Revised Loan Agreement”): ● extended the due date of our Credit Facility from October 31, 2016 to March 24, 2021 (“maturity date”); ● amended the Term Loan to approximately $6,100,000, which requires monthly payments of $101,600 (based on a five-year amortization) and which approximated the Term Loan balance under the existing Credit Facility at the date of the amendment. The Revolving Credit remains at up to $12,000,000 (subject to the amount of borrowings based on a percentage of eligible receivables as previously defined under the Amended Loan Agreement); ● released $1,000,000 of the $1,500,000 borrowing availability restriction that the lender had previously placed on the Company in connection with the insurance settlement proceeds received on July 28, 2014 by our Perma-Fix of South Georgia, Inc. (“PFSG”) facility, which suffered a fire in 2013. The Company’s lender had authorized the Company to use such proceeds for working capital purposes but had placed an indefinite reduction on our borrowing availability of $1,500,000; ● revised the interest payment options to paying an annual rate of interest due on the Revolving Credit at prime plus 1.75% or LIBOR plus 2.75% and the Term Loan at prime (3.50% at June 30, 2016) plus 2.25% or LIBOR plus 3.25%; and ● revised our annual capital spending maximum limit from $6,000,000 to $3,000,000. In connection with the amendment, the Company paid PNC a closing fee of $70,000. As a result of the amendment dated March 24, 2016, the Company recorded approximately $68,000 in loss on extinguishment of debt in accordance with ASC 470-50, “Debt – Modifications and Extinguishments,” which was included in interest expense in the accompanying Consolidated Statements of Operations. Pursuant to the amendment, the Company may terminate the Revised Loan Agreement upon 90 days’ prior written notice upon payment in full of its obligations under the Revised Loan Agreement. The Company has agreed to pay PNC 1.0% of the total financing in the event the Company pays off its obligations on or before March 23, 2017, .50% of the total financing if the Company pays off its obligations after March 23, 2017 but prior to or on March 23, 2018, and .25% of the total financing if the Company pays off its obligations after March 23, 2018 but prior to or on March 23, 2019. No early termination fee shall apply if the Company pays off its obligations after March 23, 2019. All other terms of the Amended Loan Agreement remain principally unchanged. As of June 30, 2016, the availability under our revolving credit was $1,763,000, based on our eligible receivables and includes the remaining indefinite reduction of borrowing availability of $500,000 as discussed above. The Company’s Credit Facility with PNC contains certain financial covenants, along with customary representations and warranties. A breach of any of these financial covenants, unless waived by PNC, could result in a default under our Credit Facility allowing our lender to immediately require the repayment of all outstanding debt under our Credit Facility and terminate all commitments to extend further credit. The Company failed to meet its minimum quarterly fixed charge coverage ratio (“FCCR”) requirement of 1.15:1 in the first quarter of 2016. On May 23, 2016, the Company’s lender waived this non-compliance. In connection with this waiver, the Company paid PNC a fee of $5,000 which was included in SG&A expenses. The Company met its financial covenant requirements in the second quarter of 2016 except for its quarterly FCCR requirement. The Company has obtained a waiver from its lender for this non-compliance. The Company believes that it will be able to meet its quarterly financial covenants in each of the remaining quarters of 2016 as the Company’s lender has revised the methodology to be used in calculating the FCCR (see Note 12 - “Subsequent Events – Credit Facility” for this waiver and the revision made to the methodology in calculating the FCCR in subsequent quarters). Promissory Note The Company entered into a $3,000,000 loan dated August 2, 2013 with Messrs. Robert Ferguson and William Lampson (each known as the “Lender”). As consideration for the Company receiving the loan, the Company issued to each Lender a Warrant to purchase up to 35,000 shares of the Company’s Common Stock at an exercise price of $2.23 per share. The Warrants expire on August 2, 2016. As further consideration for the loan, the Company also issued to each Lender 45,000 shares of the Company’s Common Stock. The fair value of the Warrants and Common Stock and the related closing fees incurred from this transaction were recorded as a debt discount, which is being amortized using the effective interest method over the term of the loan as interest expense – financing fees.

Commitments and Contingencies Disclosure [Text Block]	8. Commitments and Contingencies Hazardous Waste In connection with our waste management services, we process both hazardous and non-hazardous waste, which we transport to our own, or other, facilities for destruction or disposal. As a result of disposing of hazardous substances, in the event any cleanup is required, we could be a potentially responsible party for the costs of the cleanup notwithstanding any absence of fault on our part. Legal Matters In the normal course of conducting our business, we are involved in various litigation. We are not a party to any litigation or governmental proceeding which our management believes could result in any judgments or fines against us that would have a material adverse effect on our financial position, liquidity or results of future operations. Insurance The Company has a 25-year finite risk insurance policy entered into in June 2003 with American International Group, Inc. (“AIG”), which provides financial assurance to the applicable states for our permitted facilities in the event of unforeseen closure. The policy, as amended, provides for a maximum allowable coverage of $39,000,000 and has available capacity to allow for annual inflation and other performance and surety bond requirements. All of the required payments for this finite risk insurance policy, as amended, were made by 2012. As of June 30, 2016, our financial assurance coverage amount under this policy totaled approximately $38,874,000. The Company has recorded $15,498,000 in sinking fund related to this policy in other long term assets on the accompanying Consolidated Balance Sheets, which includes interest earned of $1,027,000 on the sinking fund as of June 30, 2016. Interest income for the three and six months ended June 30, 2016 was approximately $24,000 and $38,000, respectively. Interest income for the three and six month periods ended June 30, 2015, was approximately $6,000 and $14,000, respectively. If the Company so elects, AIG is obligated to pay us an amount equal to 100% of the sinking fund account balance in return for complete release of liability from both us and any applicable regulatory agency using this policy as an instrument to comply with financial assurance requirements. In August 2007, the Company entered into a second finite risk insurance policy for a term of four years for our Perma-Fix Northwest Richland, Inc. (“PFNWR”) facility with AIG. The policy provided an initial $7,800,000 of financial assurance coverage with an annual growth rate of 1.5%, which at the end of the four year term policy, provides maximum coverage of $8,200,000. The Company has made all of the required payments on this policy. As of June 30, 2016, the Company has recorded $5,927,000 in our sinking fund related to this policy in other long term assets on the accompanying Consolidated Balance Sheets, which includes interest earned of $227,000 on the sinking fund as of June 30, 2016. Interest income for the three and six months ended June 30, 2016 was approximately $5,000 and $7,000, respectively. Interest income for the three and six month periods ended June 30, 2015, was approximately $2,000 and $3,000, respectively. This policy is renewed annually at the end of the four year term with a nominal fee for the variance between the coverage requirement and the sinking fund balance. The Company has renewed this policy annually from 2011 to 2015 (with fees ranging from $41,000 to $46,000 annually). All other terms of the policy remain substantially unchanged. Letter of Credits and Bonding Requirements From time to time, we are required to post standby letters of credit and various bonds to support contractual obligations to customers and other obligations, including facility closures. As of June 30, 2016, the total amount of these bonds and letters of credit outstanding was approximately $1,514,000, of which the majority of the amount relates to various bonding requirements.

Income Tax Disclosure [Text Block]	11 . Income Taxes The Company uses an estimated annual effective tax rate, which is based on expected annual income, statutory tax rates and tax planning opportunities available in the various jurisdictions in which the Company operates, to determine its quarterly provision for income taxes. The Company had income tax benefits of $3,167,000 and $3,130,000 for continuing operations for the three and six months ended June 30, 2016, respectively, and income tax expenses of $36,000 and $71,000 for continuing operations for the three and six months ended June 30, 2015, respectively. The Company’s effective tax rates were approximately 28 .4% and 21.2% for the three and six months ended June 30, 2016, respectively, and 6.1% and (5.9%) for the three and six months ended June 30, 2015, respectively. The Company’s income tax benefits for the three and six months ended June 30, 2016 was primarily the result of a tax benefit recorded in the amount of $3,203,000 resulting from the permit impairment loss recorded for the Company’s M&EC subsidiary.

Subsequent Events [Text Block]	12. Subsequent Events Credit Facility On August 22, 2016, the Company entered into an amendment to its Revised Loan Agreement with its lender (see Note 7 – “Long Term Debt”), which waived the Company’s non-compliance with its minimum quarterly FCCR for the second quarter of 2016. In addition, the amendment revised the methodology to be used in calculating the FCCR in each of the subsequent quarters of 2016 and first quarter of 2017 and revised the maintenance requirement by the Company of its Tangible Adjusted Net Worth (as defined in the Revised Loan Agreement) at all periods from $30,000,000 to $26,000,000. The Company's lender has acknowledged the pending shut down of the Company's M&EC facility in Oak Ridge, Tennessee. Warrant Exercise As discussed in Note 7 – “Long Term Debt”, the Company issued a Warrant to each of the two Lenders in connection with a loan dated August 2, 2013. On August 2, 2016, each Lender exercised his Warrant for the purchase of 35,000 shares of our Common Stock, resulting in total proceeds paid to the Company of approximately $156,000.

Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Adopted Accounting Standards In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-03, "Simplifying the Presentation of Debt Issuance Costs." ASU 2015-03 amends existing guidance to require the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of a deferred charge asset. It is effective for annual reporting periods beginning after December 15, 2015 (including interim reporting periods), but early adoption is permitted. The Company adopted ASU 2015-03 retroactively in the first quarter of 2016. The adoption of ASU 2015-03 did not have a material impact to the Company’s results of operations, cash flows or financial position . The adoption of ASU 2015-03 resulted in a decrease in prepaid and other assets of approximately $152,000, a decrease in current portion of long-term debt of $27,000, and a decrease in long-term debt, less current portion of $125,000 for the balances as of December 31, 2015 in the accompanying Consolidated Balance Sheets.
New Accounting Pronouncements not yet Adopted, Policy [Policy Text Block]	Recently Issued Accounting Standards – Not Yet Adopted In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)." ASU 2014-09 provides a single, comprehensive revenue recognition model for all contracts with customers. The amendments in ASU 2014-09 require a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. Subsequently, in August 2015, the FASB issued ASU No. 2015-14, "Revenue from Contracts with Customers (Topic 606) Deferral of the Effective Date," that deferred the effective date of ASU 2014-09 to annual reporting periods beginning after December 15, 2017 (including interim reporting periods within those periods). In March 2016, the FASB issued ASU 2016-08, "Revenue from Contracts with Customer (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net)," which clarifies the guidance in determining revenue recognition as principal versus agent. In April 2016, the FASB issued ASU 2016-10, "Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing," which provides guidance in accounting for immaterial performance obligations and shipping and handling. In May 2016, the FASB issued ASU 2016-12, "Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients," which provides clarification on assessing the collectability criterion, presentation of sales taxes, measurement date for non-cash consideration and completed contracts at transition. Early adoption is permitted for ASU 2014-09 and the related amendment to the original effective date of period beginning after December 15, 2016 (including interim reporting periods within those periods). The ASUs may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial application. The Company is still evaluating the potential impact of adopting this guidance on our financial statements. In August 2014, the FASB issued ASU No. 2014-15, “Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.” ASU 2014-15 requires management to assess an entity’s ability to continue as a going concern, and to provide related footnote disclosure in certain circumstances. The new standard will be effective for all entities in the first annual period ending after December 15, 2016. The Company is still evaluating the potential impact of adopting this guidance on our financial statements. In July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330): Simplifying the Measurement of Inventory.” ASU In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)”. Under ASU 2016-02, an entity will be required to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. For public companies, ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, and requires a modified retrospective adoption, with early adoption permitted. The Company is still evaluating the potential impact of adopting this guidance on our financial statements. In March 2016, the FASB issued ASU 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” ASU 2016-09 simplifies several aspects related to the accounting for share-based payment transactions, including the accounting for income taxes, statutory tax withholding requirements and classification on the statement of cash flows. ASU 2016-09 is effective for interim and annual periods beginning after December 15, 2016. The Company is still evaluating the potential impact of adopting this guidance on our financial statements.
