Nature of Operations

Nature of Operations [Abstract]
Nature of operations	1. Ur-Energy Inc. (the “Company”) was incorporated on March 22, 2004 under the laws of the Province of Ontario. The Company was continued under the Canada Business Corporations Act on August 8, 2006. Headquartered in Littleton, Colorado, the Company is an exploration stage mining company, as defined by U.S. Securities and Exchange Commission (“SEC”) Industry Guide 7. The Company is engaged in uranium mining and recovery operations, with activities including the acquisition, exploration, development and production of uranium mineral resources located in Wyoming. As of August 2013, the Company commenced uranium production at its Lost Creek Project in Wyoming. Due to the nature of the uranium mining methods used by the Company on the Lost Creek Property, and the definition of “mineral reserves” under National Instrument 43-101 (“NI 43-101”), which uses the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards, the Company has not determined whether the properties contain mineral reserves. However, the Company’s “ Amended Preliminary Economic Assessment of the Lost Creek Property, Sweetwater County, Wyoming, ” February 8, 2016 (“Lost Creek PEA”), outlines the potential viability of the Lost Creek Property. The recoverability of amounts recorded for mineral properties is dependent upon the discovery of economic resources, the ability of the Company to obtain the necessary financing to develop the properties and upon attaining future profitable production from the properties or sufficient proceeds from disposition of the properties.

Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Basis of presentation These unaudited interim consolidated financial statements do not conform in all respects to the requirements of United States generally accepted accounting principles (“US GAAP”) for annual financial statements. The unaudited interim financial statements reflect all normal adjustments which in the opinion of management are necessary for a fair statement of the results for the periods presented. These unaudited interim consolidated financial statements should be read in conjunction with the audited annual consolidated financial statements for the year ended December 31, 2016. The year-end balance sheet data were derived from the audited financial statements and certain information and footnote disclosures required by US GAAP have been condensed or omitted. Earnings and loss per share calculations Diluted earnings per common share are calculated by including all options which are in-the-money based on the average stock price for the period as well as RSUs which were outstanding at the end of the quarter. The treasury stock method was applied to determine the dilutive number of options. Warrants are included only if the exercise price is less than the average stock price for the quarter. In periods of loss, the diluted loss per common share is equal to the basic loss per common share due to the anti-dilutive effect of all convertible securities. New accounting pronouncements which may affect future reporting In May 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-09, “ Revenue from Contracts with Customers (Topic 606) .” The amendments in ASU 2014-09 affect any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of non-financial assets unless those contracts are within the scope of other standards ( e.g., insurance contracts or lease contracts). This ASU will supersede the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance, and creates a Topic 606, Revenue from Contracts with Customers. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of the promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The amendments are effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early application is not permitted. We have reviewed our contracts as well as our procedures and do not anticipate any changes in the manner or timing with which we reflect our revenues. In January 2016, the FASB issued ASU 2016-1, Recognition and Measurement of Financial Assets and Financial Liabilities (Topic 825) . The amendments in this ASU supersede the guidance to classify equity securities with readily determinable fair values into different categories (that is, trading or available-for-sale) and require equity securities (including other ownership interests, such as partnerships, unincorporated joint ventures, and limited liability companies) to be measured at fair value with changes in the fair value recognized through net income. The amendments allow equity investments that do not have readily determinable fair values to be remeasured at fair value either upon the occurrence of an observable price change or upon identification of an impairment. The amendments also require enhanced disclosures about those investments. The amendments improve financial reporting by providing relevant information about an entity’s equity investments and reducing the number of items that are recognized in other comprehensive income. This guidance is effective for annual reporting beginning after December 15, 2017, including interim periods within the year of adoption, and calls for prospective application, with early application permitted. Accordingly, the standard is effective for us beginning in the first quarter of fiscal 2018. The adoption of this guidance is not expected to have a material impact on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , which requires lessees to recognize all leases, including operating leases, unless the lease is a short-term lease. ASU 2016-02 also requires additional disclosures regarding leasing arrangements. ASU 2016-02 is effective for interim periods and fiscal years beginning after December 15, 2018, and early application is permitted. Now, the only leases we hold are for vehicles, equipment, and office space in one location. The office lease is the only one which will be in effect as of the date of implementation of the standard. We have gathered the necessary information for proper disclosure of that lease once the ASU is effective. We will continue to monitor any new leases to ensure that we have all the information necessary to handle the transition to the new standard and properly report the transactions. We do not anticipate the new standard will affect our net income materially, but will result in additional fixed assets and the related lease liabilities. New accounting pronouncements which were implemented this year In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory . ASU 2015-11 requires that inventory within the scope of this ASU be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The amendments apply to all inventory, measured using average cost which is how the Company measures inventory. For all entities, the guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2016. This is consistent with our past policies and had no financial or reporting impact when implemented this quarter. In March 2016, the FASB issued ASU No. 2016-09, Compensation-Stock Compensation - Improvements to Employee Share-Based Payment Accounting (Topic 718) , which involves several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Under the new standard, income tax benefits and deficiencies are to be recognized as income tax expense or benefit in the income statement and the tax effects of exercised or vested awards should be treated as discrete items in the reporting period in which they occur. An entity should also recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period. Excess tax benefits should be classified along with other income tax cash flows as an operating activity. Regarding forfeitures, the entity may make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. This ASU is effective for fiscal years beginning after December 15, 2016 including interim periods within that reporting period. We currently recognize no income tax expense or benefit due to significant income tax credits and net operating losses which are fully reserved under a valuation allowance. There is therefore no effect on our accounting or reporting at the time of implementation in this quarter. We have made the election to continue to recognize losses from forfeitures at inception rather than when they vest or occur. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows – Restricted Cash a consensus of the FASB Emerging Task Force (Topic 230) , which addresses the presentation of restricted cash in the statement of cash flows. Under the new standard, restricted cash will be presented with cash and cash equivalents in the statement of cash flows instead of being reflected as non-cash investing or financing activities. A reconciliation of the make-up of the ending cash, cash equivalent and restricted cash balance will be required for entities who reflect restricted cash as separate items on the statement of financial position. In addition, a description of the restrictions on the cash will be required. This ASU is effective for fiscal years beginning after December 15, 2017 including interim periods within that reporting period, however early adoption is permitted. We have elected to adopt this standard as of the current quarter. Accordingly, the cash balances reflected in the Statement of Cash Flows have been increased by $7.6 million which has been the restricted cash balance since December 31, 2015. In addition, we have added note 13 – Supplemental Information to the Statement of Cash Flows which reconciles the cash balances shown on the Statement of Cash Flows with the appropriate balances on the Balance Sheet.

Assets acquired in this transaction include the Lost Creek Project, other Wyoming properties and development databases. NFU Wyoming, LLC was acquired for aggregate consideration of $20 million plus interest. Since 2005, the Company has increased its holdings adjacent to the initial Lost Creek acquisition through staking additional claims and additional property purchases and leases. There is a royalty on each of the State of Wyoming sections under lease at the Lost Creek, LC West and EN Projects, as required by law. Other royalties exist on certain mining claims at the LC South, LC East and EN Projects. Currently, there are no royalties on the mining claims in the Lost Creek, LC North or LC West Projects. Pathfinder Mines The Company acquired additional Wyoming properties when Ur-Energy USA Inc. closed a Share Purchase Agreement (“SPA”) with an AREVA Mining affiliate in December 2013. Under the terms of the SPA, the Company purchased Pathfinder Mines Corporation (“Pathfinder”) to acquire additional mineral properties. Assets acquired in this transaction include the Shirley Basin mine, portions of the Lucky Mc mine, machinery and equipment, vehicles, office equipment and development databases. Pathfinder was acquired for aggregate consideration of $6.7 million, a 5% production royalty under certain circumstances and the assumption of $5.7 million in estimated asset reclamation obligations . At June 30, 2016, the royalty expired and has been terminated.

Asset Retirement Obligations [Abstract]
Asset Retirement and Reclamation Obligations	10. Asset retirement obligations ("ARO") relate to the Lost Creek mine and Pathfinder projects and are equal to the present value of all estimated future costs required to remediate any environmental disturbances that exist as of the end of the period discounted at a risk-free rate. Included in this liability are the costs of closure, reclamation, demolition and stabilization of the mines, processing plants, infrastructure, aquifer restoration, waste dumps and ongoing post-closure environmental monitoring and maintenance costs. At June 30, 2017, the total undiscounted amount of the future cash needs was estimated to be $27.3 million. The schedule of payments required to settle the ARO liability extends through 2033. The restricted cash as discussed in note 5 is related to the surety bonds which provide security to the governmental agencies on these obligations.

Shareholders' Equity and Capital Stock	11. Stock options In 2005, the Company’s Board of Directors approved the adoption of the Company's stock option plan (the “Option Plan”). The Option Plan was most recently approved by the shareholders, including certain amendments, on May 18, 2017. Eligible participants under the Option Plan include directors, officers, employees and consultants of the Company. Under the terms of the Option Plan, stock options granted prior to the May 2017 amendment generally vest with Option Plan participants as follows: 10% at the date of grant; 22% four and one-half months after grant; 22% nine months after grant; 22% thirteen and one-half months after grant; and the balance of 24% eighteen months after the date of grant. Following the May 2017 amendment of the Option Plan, future grants of options will vest over a three-year period: 33.3% on the first anniversary, 33.3% on the second anniversary, and 33.4% on the third anniversary of the grant. The term of options remains unchanged. Activity with respect to stock options is summarized as follows: Weighted- average Options exercise price # US$ Balance, December 31, 2016 9,748,934 0.63 Granted 300,000 0.76 Exercised (549,952) 0.63 Forfeited (480,404) 0.63 Expired (870,434) 0.79 Outstanding, June 30, 2017 8,148,144 0.67 The exercise price of a new grant is set at the closing price for the shares on the Toronto Stock Exchange (TSX) on the trading day immediately preceding the grant date so there is no intrinsic value as of the date of grant. The fair value of options vested during the six months ended June 30, 2017 was $0.2 million. As of June 30, 2017, outstanding stock options are as follows: Options outstanding Options exercisable Weighted- Weighted- average average remaining Aggregate remaining Aggregate Exercise Number contractual Intrinsic Number contractual Intrinsic price of options life (years) Value of options life (years) Value Expiry US$ US$ US$ (thousands) (thousands) 0.59 0.4 30 0.4 30 07-Dec-17 0.59 0.8 16 0.8 16 25-Apr-18 0.96 1.1 - 1.1 - 01-Aug-18 0.92 1.5 - 1.5 - 27-Dec-18 1.29 1.7 - 1.7 - 31-Mar-19 0.79 2.5 - 2.5 - 12-Dec-19 0.88 2.9 - 2.9 - 29-May-20 0.66 3.1 - 3.1 - 17-Aug-20 0.62 3.4 9 3.4 9 11-Dec-20 0.56 4.5 172 4.5 55 16-Dec-21 0.79 4.7 - 4.7 - 02-Mar-22 0.67 3.0 227 2.5 110 The aggregate intrinsic value of the options in the preceding table represents the total pre-tax intrinsic value for stock options with an exercise price less than the Company’s TSX closing stock price of Cdn$0.82 as of the last trading day in the period ended June 30, 2017, that would have been received by the option holders had they exercised their options as of that date. The total number of in-the-money stock options outstanding as of June 30, 2017 was 5,289,303. The total number of in-the-money stock options exercisable as of June 30, 2017 was 3,353,402. We elect to estimate the number of awards expected to vest in lieu of accounting for forteitures when they occur. Restricted share units On June 24, 2010, the Company’s shareholders approved the adoption of the Company’s restricted share unit plan (the “RSU Plan”). The RSU Plan was approved by our shareholders most recently on May 5, 2016. Eligible participants under the RSU Plan include directors and employees of the Company. RSUs in a grant redeem on the second anniversary of the grant. Activity with respect to RSUs is summarized as follows: Number Weighted of average grant RSUs date fair value US$ Unvested, December 31, 2016 1,273,990 0.60 Vested (175,996) 0.79 Forfeited (26,654) 0.56 Unvested, June 30, 2017 1,071,340 0.59 As of June 30, 2017, outstanding RSUs are as follows: Number of Remaining Aggregate unvested life Intrinsic Grant date RSUs (years) Value US$ (thousands) August 17, 2015 161,384 0.13 102 December 11, 2015 248,226 0.45 156 December 16, 2016 661,730 1.46 417 1,071,340 1.03 675 Upon RSU vesting, the holder of an RSU will receive one common share, for no additional consideration, for each RSU held. Warrants The following represents warrant activity during the period ended June 30, 2017. Number Weighted- of average Warrants exercise price US$ Outstanding, December 31, 2016 5,844,567 0.93 Outstanding, June 30, 2017 5,844,567 0.93 As of June 30, 2017, outstanding warrants are as follows: Remaining Aggregate Exercise Number contractual Intrinsic price of warrants life (years) Value Expiry US$ US$ (thousands) 0.92 1.0 - 24-Jun-18 0.96 1.2 - 27-Aug-18 0.93 1.0 - Share-based compensation expense Share-based compensation expense was $0.4 million and $0.7 million, respectively, for the three and six months ended June 30, 2017 and $0.2 million and $0.4 million for the three and six months ended June 30, 2016, respectively. As of June 30, 2017, there was approximately $0.6 million of total unrecognized compensation expense (net of estimated pre-vesting forfeitures) related to unvested share-based compensation arrangements granted under the Option Plan and $0.4 million under the RSU Plan. The expenses are expected to be recognized over a weighted-average period of 1.2 years and 1.5 years, respectively. Cash received from stock options exercised during the three and six months ended June 30, 2017 totalled $NIL and $0.3 million, respectively, and less than $0.1 million for the three and six months ended June 30, 2016. Fair value calculations The initial fair value of options and RSUs granted is determined using the Black-Scholes option pricing model for options and the intrinsic pricing model for RSUs. There were no RSUs granted in either the six months ended June 30, 2017 or the six months ended June 30, 2016 nor were there any options granted in the six months ended June 30, 2016. The assumptions used for the options granted during the six months ended June 30, 2017 were as follows: Six months ended June 30, 2017 Expected option life (years) 3.70 Expected volatility 57.45% Risk-free interest rate 1.00% Expected dividend rate 0% Forfeiture rate 5.4% The Company estimates expected volatility using daily historical trading data of the Company’s Common Shares, because this is recognized as a valid method used to predict future volatility. The risk-free interest rates are determined by reference to Canadian Treasury Note constant maturities that approximate the expected option term. The Company has never paid dividends and currently has no plans to do so. Share-based compensation expense is recognized net of estimated pre-vesting forfeitures, which results in recognition of expense on options that are ultimately expected to vest over the expected option term. Forfeitures were estimated using actual historical forfeiture experience.

Financial instruments [Abstract]
Financial instruments	14. The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, restricted cash, deposits, accounts payable and accrued liabilities and notes payable. The Company is exposed to risks related to changes in interest rates and management of cash and cash equivalents and short-term investments. Credit risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents and restricted cash. These assets include Canadian dollar and U.S. dollar denominated certificates of deposits, money market accounts and demand deposits. These instruments are maintained at financial institutions in Canada and the United States. Of the amount held on deposit, approximately $0.7 million is covered by the Canada Deposit Insurance Corporation, the Securities Investor Protection Corporation or the United States Federal Deposit Insurance Corporation, leaving approximately $14.2 million at risk at June 30, 2017 should the financial institutions with which these amounts are invested be rendered insolvent. The Company does not consider any of its financial assets to be impaired as of June 30, 2017. All of the Company’s customers have Moody’s Baa or greater ratings and purchase from the Company under contracts with set prices and payment terms. Liquidity risk Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they come due. As at June 30, 2017, the Company’s financial liabilities consisted of trade accounts payable and accrued trade and payroll liabilities of $1.369 million which are due within normal trade terms of generally 30 to 60 days, a note payable which will be payable over a period of four years. On May 27, 2016, we entered into an At Market Issuance Sales Agreement with MLV & Co. LLC and FBR Capital Markets & Co. under which we may, from time to time, issue and sell Common Shares at market prices on the NYSE American or other U.S. market through the distribution agents for aggregate sales proceeds of up to $10,000,000. During 2017, we have sold 1,536,169 Common Shares under the sales agreement at an average price of $0.76 per share for gross proceeds of $1.2 million. After deducting transaction fees and commissions we received net proceeds of $1.1 million. We made our final contract sale for 2017 in July, which was for 109,000 pounds at $35.35 per pound. We purchased the pounds delivered for $20.15. At this point, we therefore do not have any additional contract revenues until next January when we have scheduled deliveries to our customers. In the interim, we currently have over 160,000 pounds of uranium at the conversion facility and will continue to produce inventory through the end of the year. We therefore have a substantial amount of uranium which can be sold under spot contracts during the latter half of the year if it is advantageous to do so. We expect that any major capital projects will be funded by operating cash flow, cash on hand or additional financing as required. If these cash sources are not sufficient, certain capital projects could be delayed, or alternatively we may need to pursue additional debt or equity financing to which there is no assurance that such financing will be available at all or on terms acceptable to us Sensitivity analysis The Company has completed a sensitivity analysis to estimate the impact that a change in interest rates would have on the net loss of the Company. This sensitivity analysis shows that a change of +/- 100 basis points in interest rate would have a negligible effect on either the six months ended June 30, 2017 or the comparable six months in 2016. The financial position of the Company may vary at the time that a change in interest rates occurs causing the impact on the Company’s results to differ from that shown above.

Summary of Significant Accounting Policies [Abstract]
Basis of presentation	Basis of presentation These unaudited interim consolidated financial statements do not conform in all respects to the requirements of United States generally accepted accounting principles (“US GAAP”) for annual financial statements. The unaudited interim financial statements reflect all normal adjustments which in the opinion of management are necessary for a fair statement of the results for the periods presented. These unaudited interim consolidated financial statements should be read in conjunction with the audited annual consolidated financial statements for the year ended December 31, 2016. The year-end balance sheet data were derived from the audited financial statements and certain information and footnote disclosures required by US GAAP have been condensed or omitted.
Earnings and loss per share calculations	Earnings and loss per share calculations Diluted earnings per common share are calculated by including all options which are in-the-money based on the average stock price for the period as well as RSUs which were outstanding at the end of the quarter. The treasury stock method was applied to determine the dilutive number of options. Warrants are included only if the exercise price is less than the average stock price for the quarter. In periods of loss, the diluted loss per common share is equal to the basic loss per common share due to the anti-dilutive effect of all convertible securities.
New accounting pronouncements which may affect future reporting	New accounting pronouncements which may affect future reporting In May 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-09, “ Revenue from Contracts with Customers (Topic 606) .” The amendments in ASU 2014-09 affect any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of non-financial assets unless those contracts are within the scope of other standards ( e.g., insurance contracts or lease contracts). This ASU will supersede the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance, and creates a Topic 606, Revenue from Contracts with Customers. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of the promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The amendments are effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early application is not permitted. We have reviewed our contracts as well as our procedures and do not anticipate any changes in the manner or timing with which we reflect our revenues. In January 2016, the FASB issued ASU 2016-1, Recognition and Measurement of Financial Assets and Financial Liabilities (Topic 825) . The amendments in this ASU supersede the guidance to classify equity securities with readily determinable fair values into different categories (that is, trading or available-for-sale) and require equity securities (including other ownership interests, such as partnerships, unincorporated joint ventures, and limited liability companies) to be measured at fair value with changes in the fair value recognized through net income. The amendments allow equity investments that do not have readily determinable fair values to be remeasured at fair value either upon the occurrence of an observable price change or upon identification of an impairment. The amendments also require enhanced disclosures about those investments. The amendments improve financial reporting by providing relevant information about an entity’s equity investments and reducing the number of items that are recognized in other comprehensive income. This guidance is effective for annual reporting beginning after December 15, 2017, including interim periods within the year of adoption, and calls for prospective application, with early application permitted. Accordingly, the standard is effective for us beginning in the first quarter of fiscal 2018. The adoption of this guidance is not expected to have a material impact on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , which requires lessees to recognize all leases, including operating leases, unless the lease is a short-term lease. ASU 2016-02 also requires additional disclosures regarding leasing arrangements. ASU 2016-02 is effective for interim periods and fiscal years beginning after December 15, 2018, and early application is permitted. Now, the only leases we hold are for vehicles, equipment, and office space in one location. The office lease is the only one which will be in effect as of the date of implementation of the standard. We have gathered the necessary information for proper disclosure of that lease once the ASU is effective. We will continue to monitor any new leases to ensure that we have all the information necessary to handle the transition to the new standard and properly report the transactions. We do not anticipate the new standard will affect our net income materially, but will result in additional fixed assets and the related lease liabilities. New accounting pronouncements which were implemented this year In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory . ASU 2015-11 requires that inventory within the scope of this ASU be measured at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The amendments apply to all inventory, measured using average cost which is how the Company measures inventory. For all entities, the guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2016. This is consistent with our past policies and had no financial or reporting impact when implemented this quarter. In March 2016, the FASB issued ASU No. 2016-09, Compensation-Stock Compensation - Improvements to Employee Share-Based Payment Accounting (Topic 718) , which involves several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Under the new standard, income tax benefits and deficiencies are to be recognized as income tax expense or benefit in the income statement and the tax effects of exercised or vested awards should be treated as discrete items in the reporting period in which they occur. An entity should also recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period. Excess tax benefits should be classified along with other income tax cash flows as an operating activity. Regarding forfeitures, the entity may make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. This ASU is effective for fiscal years beginning after December 15, 2016 including interim periods within that reporting period. We currently recognize no income tax expense or benefit due to significant income tax credits and net operating losses which are fully reserved under a valuation allowance. There is therefore no effect on our accounting or reporting at the time of implementation in this quarter. We have made the election to continue to recognize losses from forfeitures at inception rather than when they vest or occur. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows – Restricted Cash a consensus of the FASB Emerging Task Force (Topic 230) , which addresses the presentation of restricted cash in the statement of cash flows. Under the new standard, restricted cash will be presented with cash and cash equivalents in the statement of cash flows instead of being reflected as non-cash investing or financing activities. A reconciliation of the make-up of the ending cash, cash equivalent and restricted cash balance will be required for entities who reflect restricted cash as separate items on the statement of financial position. In addition, a description of the restrictions on the cash will be required. This ASU is effective for fiscal years beginning after December 15, 2017 including interim periods within that reporting period, however early adoption is permitted. We have elected to adopt this standard as of the current quarter. Accordingly, the cash balances reflected in the Statement of Cash Flows have been increased by $7.6 million which has been the restricted cash balance since December 31, 2015. In addition, we have added note 13 – Supplemental Information to the Statement of Cash Flows which reconciles the cash balances shown on the Statement of Cash Flows with the appropriate balances on the Balance Sheet.
