NATURE OF OPERATIONS AND ACCOUN

NATURE OF OPERATIONS AND ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2019
Organization, Consolidation and Presentation of Financial Statements [Abstract]
NATURE OF OPERATIONS AND ACCOUNTING POLICIES	NATURE OF OPERATIONS AND ACCOUNTING POLICIES Nature of Operations . Era Group Inc. (“Era Group”) and its consolidated subsidiaries (collectively referred to as the “Company”) is one of the largest helicopter operators in the world and the longest serving helicopter transport operator in the United States (“U.S.”), which is its primary area of operation. The Company is primarily engaged in transportation services to the offshore oil and gas exploration, development and production industry. Its major customers are international, independent and major integrated oil and gas companies and U.S. government agencies. In addition to serving the oil and gas industry, the Company provides emergency response services and utility services. The Company operates a Federal Aviation Administration (“FAA”) approved maintenance repair station in Lake Charles, Louisiana. Basis of Consolidation . The consolidated financial statements include the accounts of Era Group Inc., its wholly-owned subsidiaries and entities that meet the criteria of VIEs of which the Company is the primary beneficiary. All significant intercompany accounts and transactions are eliminated in consolidation. The Company employs the equity method of accounting for investments in business ventures when it has the ability to exercise significant influence over the operating and financial policies of the ventures. The Company reports such investments in the accompanying consolidated balance sheets as equity investments and advances. The Company reports its share of earnings or losses of equity investees in the accompanying consolidated statements of operations as equity earnings (losses), net of tax. Use of Estimates . The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Such estimates include, among other items, those related to allowance for doubtful accounts, useful lives of property and equipment, inventories, income tax provisions, impairments, fair values used in purchase price allocations and certain accrued and contingent liabilities. Actual results could differ from those estimates and those differences may be material. Reclassification. Certain amounts reported for prior periods in the consolidated financial statements have been reclassified to conform with the current period’s presentation. Cash Equivalents . The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Cash equivalents consist of overnight investments. Supplemental Cash Flow Information. The following table sets forth the Company’s reconciliation of cash, cash equivalents and restricted cash reported within the Consolidated Statement of Cash Flows for the years ended December 31, 2019 , 2018 and 2017, respectively, (in thousands): 2019 2018 2017 Cash and cash equivalents $ 117,366 $ 50,753 $ 13,583 Restricted cash (1) — — 3,250 Total cash, cash equivalents and restricted cash shown in the Consolidated Statement of Cash Flows $ 117,366 $ 50,753 $ 16,833 (1) Restricted cash represents amounts deposited in escrow accounts at the end of each period. Escrow deposits are shown as a separate line item in the consolidated balance sheet. Trade Receivables . Customers are primarily international, independent and major integrated exploration, development and production companies, international helicopter operators and U.S. government agencies. Customers are typically granted credit on a short-term basis, and related credit risks are considered minimal. The Company routinely reviews its trade receivables and makes provisions for probable doubtful accounts; however, those provisions are estimates and actual results could differ from those estimates and those differences may be material. Trade receivables are deemed uncollectible and removed from accounts receivable and the allowance for doubtful accounts when collection efforts have been exhausted. Allowance for doubtful accounts for the years ended December 31, 2019 , 2018 and 2017 were as follows (in thousands): 2019 2018 2017 Balance at beginning of period $ 261 $ 1,196 $ 1,219 Additional allowances charged to expense 41 82 144 Recovery of previously reserved accounts (100 ) (127 ) (82 ) Write-offs (145 ) (760 ) (68 ) Foreign currency adjustments (2 ) (130 ) (17 ) Balance at end of period $ 55 $ 261 $ 1,196 Concentrations of Credit Risk . The Company is exposed to concentrations of credit risk relating to its receivables due from customers in the industries described above. The Company does not generally require collateral or other security to support its outstanding receivables. The Company minimizes its credit risk relating to receivables by performing ongoing credit evaluations. The Company is also exposed to concentrations of credit risk associated with cash and cash equivalents. The Company minimizes its credit risk relating to these positions by monitoring the financial condition of the financial institutions and counterparties involved and by primarily conducting business with large, well-established financial institutions and diversifying its counterparties. The Company’s two largest customers comprised 39% and 52% of net trade receivables as of December 31, 2019 and 2018 , respectively. Inventories . Inventories are stated at the lower of average cost or net realizable value and consist primarily of spare parts and fuel. The Company establishes an allowance to accrue for the retirement of the cost of spare parts expected to be on hand at the end of a fleet’s life over the service lives of the related equipment, taking into account the estimated salvage value of the parts. The following table is a roll forward of the allowance related to obsolete and excess inventory for the years ended December 31, 2019 , 2018 and 2017 (in thousands): 2019 2018 2017 Balance at beginning of period $ 3,246 $ 3,739 $ 4,012 Increase (decrease) in allowances, net (1) 15 (493 ) (273 ) Balance at end of period $ 3,261 $ 3,246 $ 3,739 (1) Includes $0.1 million elimination of H225 inventory reserve for 2017. Property and Equipment . Property and equipment, stated at cost, is depreciated using the straight-line method over the estimated useful life of the asset to an estimated salvage value. With respect to helicopters, the estimated useful life is typically based upon a newly built asset being placed into service and represents the point at which it is typically not justifiable for the Company to continue to operate the asset in the same or similar manner. From time to time, the Company may acquire older assets that have already exceeded the Company’s useful life policy, in which case the Company depreciates such assets based on its best estimate of remaining useful life. The Company reviews the estimated useful lives and salvage values of its property and equipment on an ongoing basis for any changes in estimates. There were no such changes during the years ended December 31, 2019 , 2018 and 2017 . As of December 31, 2019 , the estimated useful life (in years) of the Company’s categories of new property and equipment was as follows: Helicopters (estimated salvage value at 40% of cost) 15 Machinery, equipment and spares 5 Buildings and leasehold improvements 10-30 Furniture, fixtures, vehicles and other 3-5 Equipment maintenance and repair costs and the costs of routine overhauls and inspections performed on helicopter engines and major components are charged to operating expense as incurred. Expenditures that extend the useful life or improve the marketing and commercial characteristics of equipment, as well as major improvements to other properties, are capitalized. The Company engages a number of third-party vendors to maintain the engines and certain components on some of its helicopter models under programs known as power-by-hour (“PBH”) maintenance contracts. These programs require the Company to pay for the maintenance service ratably over the contract period, typically based on actual flight hours. PBH providers generally bill monthly based on hours flown in the prior month, and the costs are expensed as incurred. In the event the Company places a helicopter in a program after a maintenance period has begun, it may be necessary to pay an initial buy-in charge based on hours flown since the previous maintenance event. The buy-in charge is normally recorded as a prepaid expense and amortized as an operating expense over the remaining PBH contract period. If a helicopter is sold or otherwise removed from a program before the scheduled maintenance work is carried out, the Company may be able to recover part of its payments to the PBH provider, in which case the Company records a reduction to operating expense. The Company also incurs repairs and maintenance expense through vendor arrangements whereby the Company obtains repair quotes and authorizes service through a repair order process. Under these arrangements, the Company records the repairs and maintenance cost as the work is completed. As a result, the timing of repairs and maintenance may result in operating expenses varying substantially when compared with a prior year or prior quarter if a disproportionate number of repairs, refurbishments or overhauls for components that are not covered under PBH arrangements are performed during a period. Certain interest costs incurred during the construction of equipment are capitalized as part of the assets’ carrying values and are amortized over such assets’ estimated useful lives.The Company did not capitalize any interest during the year ended December 31, 2019 . The Company capitalized interest of $0.1 million and $0.5 million during the years ended December 31, 2018 and 2017 , respectively. As of December 31, 2019 and 2018 , construction in progress, which is a component of property and equipment, included capitalized interest of $0.7 million . Leases. The Company determines if an arrangement is a lease at inception or during modification or renewal of an existing lease. Operating leases are maintained for a number of fixed assets including land, hangars, buildings, fuel tanks and tower sites. The right-of-use assets associated with these leases are reflected under long-term assets; the current portion of the long-term payables are reflected under other current liabilities; and the payables on lease agreements past one year are recorded as long-term liabilities on the Company’s consolidated balance sheets. For those contracts with terms of twelve months or less, the lease expense is recognized on a straight-line basis over the lease term and recorded in operating expenses on the consolidated statement of operations. As most of the Company’s leases do not provide an implicit rate, the incremental borrowing rate based on the information available at commencement date is used to determine the present value of future payments. Most of the Company’s lease agreements allow the option of renewal or extension, which are considered a part of the lease term. When it is reasonably certain that a lease will be extended, this is incorporated into the calculations. Impairment of Long-Lived Assets . The Company performs an impairment analysis on long-lived assets used in operations when events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. The Company’s long-lived assets are grouped at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of other groups of assets, which is generally at the fleet group level. If an impairment is indicated for the asset group classified as held and used, an impairment evaluation will be performed. Asset impairment evaluations are based on estimated undiscounted cash flows over the remaining useful life for the assets being evaluated. If the sum of the expected future cash flows is less than the carrying amount of the asset group, the Company would be required to recognize an impairment loss. During 2017, the Company concluded that the cash flows associated with its H225 heavy helicopters are largely independent from the cash flows associated with the remainder of the fleet and should be evaluated separately for impairment. The Company performed an impairment analysis on the H225 helicopters, capital parts and related inventory and determined that the projected undiscounted cash flows over the remaining useful life were less than the carrying amount. In determining the fair value, the Company used a cost approach, which begins with the replacement cost of a new asset and adjusts for age and functional and economic obsolescence. The inputs used in the Company’s fair value estimate were from Level 3 of the fair value hierarchy discussed in Note 2. As of December 31, 2019 , the Company recorded a $1.6 million impairment charge on its last remaining H225 helicopter. In 2018 and 2017 , the Company recorded a $1.0 million and $117.0 million impairment charge on its H225 helicopters, respectively. Impairment of Equity Investees . For equity investees held, the Company performs regular reviews of each investee’s financial condition, the business outlook for its products and services, and its present and projected results and cash flows. When an investee has experienced consistent declines in financial performance or difficulties in raising capital to continue operations, and when the Company expects the decline to be other-than-temporary, the investment is written down to fair value. Actual results may vary from estimates due to the uncertainty regarding the projected financial performance of investees, the severity and expected duration of declines in value and the available liquidity in the capital markets to support the continuing operations of the investees in which the Company has investments. For the years ended December 31, 2019 , 2018 and 2017 , the Company did not recognize any impairment charges. During the year ended December 31, 2019 , the Company sold its equity investment in Dart Holding Company Ltd. (“Dart”) joint venture, see note 5 for details on sale of the joint venture. As of December 31, 2019 , the Company did not have any equity investees. Intangible Assets . Intangible assets with indefinite lives are recorded during purchase price accounting in a business combination. The Company performs an annual impairment test of indefinite lived intangible assets and interim tests to the extent indicators of impairment develop between annual impairment tests. The Company’s impairment review process compares the fair value to the book value. To determine its fair value, the Company uses a discounted future cash flow approach that uses estimates including, among others, projected utilization of its fleet and contract rates. These estimates are reviewed each time the Company tests indefinite lived assets for impairment. While the Company believes its estimates and assumptions are reasonable, variations from those estimates could produce materially different results. Intangible assets with finite useful lives are amortized over their respective estimated useful lives. During the year ended December 31, 2019 the Company recorded a $1.0 million impairment charge on its indefinite lived intangible assets related to its subsidiary in Colombia. This amount is included in loss on impairment on the consolidated statement of operations. As of December 31, 2019 , the Company had indefinite lived intangible assets of $0.1 million and intangible assets with finite lives of less than $0.1 million . Business Combinations. The Company recognizes, with certain exceptions, 100 % of the fair value of assets acquired, liabilities assumed, and non controlling interests when the acquisition constitutes a change in control of the acquired entity. Shares issued in consideration for a business combination, contingent consideration arrangements and pre-acquisition loss and gain contingencies are all measured and recorded at their acquisition-date fair value. Subsequent changes to fair value of contingent consideration arrangements are generally reflected in earnings. Acquisition-related transaction costs are expensed as incurred, and any changes in an acquirer’s existing income tax valuation allowances and tax uncertainty accruals are recorded as an adjustment to income tax expense. The operating results of entities acquired are included in the accompanying consolidated statements of operations from the date of acquisition. Deferred Financing Costs. Deferred financing costs incurred in connection with the issuance of debt are amortized over the life of the related debt using the effective interest rate method for term loans and straight line method for revolving credit facilities. Amortization expense for deferred financing costs totaled $ 1.0 million , $1.4 million and $1.1 million during the years ended December 31, 2019 , 2018 and 2017 , respectively, including the write-off of $0.4 million of debt issuance costs in 2018, in connection with an amendment to the Company’s amended and restated senior secured revolving credit facility (the “Revolving Credit Facility”). Such amortization expense is included in interest expense in the consolidated statements of operations. Revenue Recognition . The Company recognizes revenues for flight services and emergency response services with the passing of each day as the Company has the right to consideration from its customers in an amount that corresponds directly with the value to the Company’s customer for the performance completed to date. Therefore, the Company has elected to exercise the right to invoice practical expedient in its adoption of ASC 606. The right to invoice represents a method for recognizing revenue over time using the output measure of “value to the customer” which is an objective measure of an entity’s performance in a contract. The Company typically invoices its customers on a monthly basis for revenues earned during the prior month with payment terms of 30 days. The Company’s customer arrangements do not contain any significant financing component for its customers. Income Taxes . Era Group and its majority-owned U.S. subsidiaries file a consolidated U.S. federal tax return. Era Group’s foreign consolidated subsidiaries each file tax returns in their applicable jurisdictions. Deferred income tax assets and liabilities have been provided in recognition of the income tax effect attributable to the book and tax basis differences of assets and liabilities reported in the accompanying consolidated financial statements. Deferred tax assets or liabilities are provided using the enacted tax rates expected to apply to taxable income in the periods in which they are expected to be settled or realized. Interest and penalties relating to uncertain tax positions are recognized in interest expense and administrative and general expense, respectively, in the accompanying consolidated statements of operations. The Company records a valuation allowance to reduce its deferred tax assets if it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company has evaluated the newly enacted global intangible low-taxed income (GILTI) provisions, which could subject its foreign earnings to a minimum level of tax and has decided to make an election to treat these costs as period costs. Foreign Currency Transactions . The functional currency for each of the Company’s foreign entities is the U.S. dollar. From time to time, the Company enters into transactions denominated in currencies other than its functional currency. Gains and losses resulting from changes in currency exchange rates between the functional currency and the currency in which a transaction is denominated are included in foreign currency gains (losses), net in the accompanying consolidated statements of operations in the period which the currency exchange rates change. Earnings (Loss) Per Common Share. Basic earnings (loss) per common share of the Company are computed based on the weighted average number of common shares issued and outstanding during the relevant periods. Diluted earnings (loss) per common share of the Company are computed based on the weighted average number of common shares issued and outstanding plus the effect of potentially dilutive securities through the application of the if-converted method and/or treasury method. Savings Plan. The Company provides a defined contribution plan (the “Savings Plan”) for its eligible U.S.-based employees. The Savings Plan provides for qualified, non-elective Company contributions in an amount equal to 3% of each employee’s eligible pay plus an amount equal to 100% of an employee’s first 3% of wages invested in the Savings Plan and immediate and full vesting in the Company’s contributions. The Savings Plan is subject to annual review by the Board of Directors of Era Group (the “Board of Directors”). The Company’s Savings Plan costs were $2.5 million , $2.3 million and $2.4 million , respectively, for the years ended December 31, 2019 , 2018 and 2017 . Recent Accounting Pronouncements. - Adopted. In February 2016, the FASB issued ASU No. 2016-02, “Leases” (ASU No. 2016-02), which establishes comprehensive accounting and financial reporting requirements for leasing arrangements. This ASU supersedes the existing requirements in FASB ASC Topic 840, “Leases,” and requires lessees to recognize substantially all lease assets and lease liabilities on the balance sheet. The provisions of this ASU also modified the definition of a lease and outline requirements for recognition, measurement, presentation and disclosure of leasing arrangements by both lessees and lessors. The ASU was effective for interim and annual periods beginning after December 15, 2018, and early adoption of the standard was permitted. Entities were required to adopt the ASU using a modified retrospective approach, subject to certain optional practical expedients, and apply the provisions of this ASU to leasing arrangements existing at or entered into after the earliest comparative period presented in the financial statements. In July 2018 this ASU was further amended by the provisions of ASU No. 2018-11, “Targeted Improvements” to Topic 842 whereby the FASB decided to provide an alternate transition method by allowing entities to initially apply the new leases standard at the adoption date (such as January 1, 2019, for calendar year-end public business entities) and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption consistent with preparers’ requests. The Company adopted the amended ASU No. 2018-11 effective January 1, 2019 using the current-period adjustment method, however upon adoption of the standard the Company determined that a cumulative-effect adjustment to the opening balance of retained earnings in that period was not required. The Company also elected an optional practical expedient to retain its former classification of leases, and as a result, the initial impact of adopting this new standard did not have a material impact to its consolidated financial statements. Additionally, the Company elected not to bifurcate and separately account for non lease components contained in a single contract. In August 2018, the FASB issued ASU No. 2018-15, “Intangibles-Goodwill and Other-Internal-Use Software” (Subtopic 350-40), providing guidance addressing a customer's accounting for implementation costs incurred in a cloud computing arrangement (“CCA”) that is considered a service contract. Under the new guidance, implementation costs for a CCA are evaluated for capitalization using the same approach as implementation costs associated with internal-use software and should be expensed over the term of the hosting arrangement, which includes any reasonably certain renewal periods. The new guidance is effective for fiscal years beginning after December 15, 2019 for calendar year-end public business entities. Early adoption is permitted, including adoption in any interim period. The Company will not take possession of implemented software and will rely on vendors to host the software, thus determining the cloud computing arrangements are service contracts. The Company adopted ASU No. 2016-13, effective January 1, 2019, and has appropriately accounted for the implementation costs of the cloud computing arrangements entered into in the first half of 2019. The adoption of ASU-2018-15 did not have a material impact on the Company’s consolidated financial statements. New Accounting Standards - Not Yet Adopted. In January 2020, the FASB issued ASU No. 2020-01, “Investments-Equity Securities” Topic 321, “Investments-Equity Method and Joint Ventures” Topic 323 and “Derivatives and Hedging” Topic 815 (ASU No. 2020-01) as an update to ASU No. 2016-01 “Financial Instruments-Overall”, further clarifying the interaction between the accounting for equity securities, equity method investments, and certain derivative instruments. This ASU clarifies that a company should consider observable transactions that require a company to either apply or discontinue the equity method of accounting under Topic 323, for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. With this update, the FASB aims to clarify that, when determining the accounting for certain forward contracts and purchased options a company should now consider, whether upon settlement or exercise, if the underlying securities would be accounted for under the equity method or fair value option. The FASB expects this ASU to reduce diversity in practice and increase comparability of the accounting for these interactions. This ASU is effective for interim and annual periods beginning after December 15, 2020. The Company is evaluating the potential impact of adopting this ASU but does not expect such adoption to have a material impact on its consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, “Measurement of Credit Losses on Financial Instruments” (ASU No. 2016-13), which sets forth the current expected credit loss model, a new forward-looking impairment model for certain financial instruments based on expected losses rather than incurred losses. The ASU is effective for interim and annual periods beginning after December 15, 2019, and early adoption of the standard is permitted. Entities are required to adopt this ASU using a modified retrospective approach, subject to certain limited exceptions. The Company has evaluated the potential impact of adopting this ASU and believes such adoption will not have a material impact on its consolidated financial statements. In August 2018, the FASB issued ASU-2018-13, “Fair Value Measurements” (ASU No. 2018-13, update to topic ASC-820), providing guidance for the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period, and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information (such as the median or arithmetic average) in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements. ASU-2018-13 will be effective for interim and annual periods beginning December 15, 2019. The Company has not adopted this ASU and believes such adoption will not have a material impact on its consolidated financial statements.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS The fair value of an asset or liability is the price that would be received to sell an asset or transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The Company utilizes a fair value hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value and defines three levels of inputs that may be used to measure fair value. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability either directly or indirectly, including quoted prices for similar assets or liabilities in active markets, quoted prices in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, or inputs derived from observable market data. Level 3 inputs are unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets or liabilities. As of December 31, 2019 and 2018 , the Company did not have any assets or liabilities that are measured at fair value on a recurring basis. The estimated fair values of the Company’s other financial assets and liabilities as of December 31, 2019 and 2018 were as follows (in thousands): Carrying Amount Level 1 Level 2 Level 3 December 31, 2019 LIABILITIES Long-term debt, including current portion $ 160,149 $ — $ 166,691 $ — December 31, 2018 LIABILITIES Long-term debt, including current portion $ 162,275 $ — $ 159,367 $ — The carrying values of cash and cash equivalents, receivables and accounts payable approximate fair value. The fair value of the Company’s long-term debt was estimated using discounted cash flow analysis based on estimated current rates for similar types of arrangements. Considerable judgment was required in developing certain of the estimates of fair value and, accordingly, the estimates presented herein are not necessarily indicative of the amounts that the Company could realize in a current market exchange. Investments. In 2019, the Company purchased $5.0 million of corporate securities and later in 2019, the Company sold these corporate securities for cash proceeds of $4.4 million resulting in a net loss of $0.6 million .

LEASES

LEASES	12 Months Ended

Leases [Abstract]
LEASES	LEASES The Company leases land, hangars, buildings, fuel tanks and tower sites under operating lease agreements. The Company determines if an arrangement is a lease at inception, and many of these leases offer an option for renewal or extension. The adoption of ASC 842 allows the Company to retain its current classification of leases, and the optional practical expedience rule has allowed the use of the current-period adjustment method to recognize a cumulative-effect adjustment to the opening balance of retained earnings in the current period rather than the restatement of prior year lease amounts. The majority of the bases from which the Company operates are leased, with current remaining terms between one year and fifty-nine years . The lease expense on those contracts with initial terms of twelve months or less are recognized on a straight-line basis over the lease term and are not recorded on the balance sheet. The Company does not currently maintain any finance leases and has only operating lease agreements. The Company’s maturity analysis of lease payments under operating leases that had initial terms in excess of one year as of December 31, 2018 was as follows (in thousands): Minimum Payments 2019 $ 1,573 2020 1,530 2021 987 2022 562 2023 495 Years subsequent to 2023 7,952 Total future minimum lease payments $ 13,099 The Company’s maturity analysis of lease payments under operating leases that have initial terms in excess of one year as of December 31, 2019 was as follows (in thousands): Minimum Payments 2020 $ 2,273 2021 1,801 2022 1,367 2023 1,314 2024 1,013 Years subsequent to 2024 8,370 Total future minimum lease payments 16,138 Less: imputed interest 6,550 Present value of lease liabilities $ 9,588 During the year ended December 31, 2019 , the Company recognized $4.0 million of operating lease expense.

Reported balances: Other current liabilities $ 1,773 Long-term lease liabilities 7,815 Total operating lease liabilities $ 9,588 As of December 31, 2019 , other information related to these leases was as follows: Weighted average remaining lease term 16 years Weighted average discount rate 6.11 % Cash paid for amounts included in the measurement of lease liabilities during the year ended December 31, 2019 (in thousands) $ 2,296 The Company generates revenues as a lessor from its dry-leasing line of service that require a fixed monthly fee for the customer’s right to use the helicopter and, where applicable, additional charges as compensation for any support the Company may provide to the customer. Revenues from dry-leasing contracts are shown on the face of the statement of operations. In 2018, the Company disposed of six H225 heavy helicopters through sales-type leases. During the year ended December 31, 2019 , the Company recognized interest income on these leases of $1.7 million . During the year ended December 31, 2019 , the Company completed the final sale of two of these helicopters and received cash proceeds of $5.0 million .

VARIABLE INTEREST ENTITIES AND EQUITY INVESTMENTS AND ADVANCES	VARIABLE INTEREST ENTITIES AND EQUITY INVESTMENTS AND ADVANCES VIEs Aeróleo . On July 1, 2011, the Company acquired a 50% economic interest and a 20% voting interest in Aeróleo, a Brazilian entity that provides helicopter transport services to the Brazilian offshore oil and gas industry, for $4.8 million in cash. The Company and its original partner also each loaned Aeróleo $6.0 million at an interest rate of 6.0% per annum. On October 1, 2015, the Company’s original partner completed a transfer of its 50% economic and 80% voting interest in Aeróleo to a third party. In connection with the transfer, the Company entered into a shareholders’ agreement with its new partner that required supermajority shareholder and/or board approval of specified, significant actions, and a put/call option arrangement which gave the Company the right to purchase at any time, and the new partner the right to put to the Company after two years, the new partner’s interest in Aeróleo. The Company has the ability to direct activities that most significantly affect Aeróleo’s financial performance, making the Company the primary beneficiary. As a result, the Company concluded that Aeróleo was a variable interest entity and therefore should be consolidated into the Company’s financial statements. The Company’s consolidated balance sheets at December 31, 2018 included assets of Aeróleo totaling $11.9 million and liabilities of $4.5 million . The creditors for such liabilities do not have recourse to Era Group or its subsidiaries other than Aeróleo. In the fourth quarter of 2019, the Company exercised its contractual call option to purchase the remaining 50% economic interest and 80% voting interest from the Company’s partner in Aeróleo, making it a wholly-owned subsidiary as of December 31, 2019 . The amount paid to effect this purchase was not material. Joint Ventures Dart. Era DHS LLC, a wholly-owned subsidiary of the Company, acquired 49% of the capital stock of Dart Helicopter Services LLC (“Dart Helicopters”), a sales, marketing and parts manufacturing organization based in North America that engineers and manufactures after-market parts and equipment for sale to helicopter manufacturers and operators. During 2009, the Company provided a $0.3 million loan to Dart Helicopters with a maturity of June 2012 at an annual interest rate of 5.0% , which was payable quarterly with principal due at maturity. On February 28, 2011, the Company made an additional investment of $5.0 million in Dart Helicopters, and on July 31, 2011, contributed its ownership in Dart Helicopters to Dart in exchange for a 50% economic and voting interest in Dart and a note receivable of $5.1 million . The note receivable had a balance of $2.3 million at December 31, 2018 and was paid in full in 2019. During the year ended December 31, 2019 , the Company in conjunction with its 50% joint venture partner entered into an agreement to sell Dart. The transaction closed on April 1, 2019, for gross proceeds of $38.0 million , including payment of the note receivable in March 2019, and net gains of $10.9 million . In the first quarter of 2019, the Company purchased $0.6 million of products and services from Dart, while it was still a joint venture. During each of the years ended December 31, 2018 and 2017 , the Company purchased $2.0 million of products and services from Dart. Purchases from Dart are included in operating expenses on the consolidated statements of income, and the note receivable was included in equity investments and advances on the consolidated balance sheets. As of December 31, 2018 , equity investments and advances in Dart was $27.1 million . During the year ended December 31, 2018, the Company received dividends of $1.0 million from Dart. Era Training Center. Era Training Center LLC (“Era Training Center”) previously operated flight training devices and provided training services to the Company and third-party customers. During the years ended December 31, 2018 and 2017 , the Company provided helicopter, management and other services to the joint venture totaling $0.1 million and $0.2 million , respectively, and incurred $0.2 million and $0.5 million , respectively, for simulator fees. During the year ended December 31, 2018, the Company entered into an agreement to dissolve Era Training Center in exchange for the settlement of an existing promissory note with an outstanding principal amount of $3.6 million by acquiring the assets of the joint venture. The agreement included the sale of three simulators to the Company for $2.9 million , partial ownership in a fourth simulator for $0.4 million and a note receivable from the Company’s partner in Era Training Center for $0.4 million . Combined Condensed Financial Statements Summarized financial information for the Company’s equity investments and advances in Dart as of December 31, 2018 and for the years ended December 31, 2018 and 2017 was as follows (in thousands): 2018 Current assets $ 31,332 Non-current assets 30,613 Current liabilities 7,007 Non-current liabilities 5,558 2018 2017 Operating revenues $ 45,602 $ 42,891 Costs and expenses: Operating and administrative 36,592 35,983 Depreciation and amortization 1,754 1,603 Total costs and expenses 38,346 37,586 Operating income $ 7,256 $ 5,305 Net income $ 4,912 $ 3,603 Summarized financial information for the Company’s equity investments and advances in all other investees for the years ended December 31, 2018 and 2017 was as follows (in thousands): 2018 2017 Operating revenues $ 170 $ 581 Costs and expenses: Operating and administrative 63 367 Depreciation and amortization 377 503 Total costs and expenses 440 870 Operating income $ (270 ) $ (289 ) Net income (loss) $ (442 ) $ (527 ) As of December 31, 2018, cumulative undistributed net earnings of equity investees included in the Company’s consolidated retained earnings was $6.0 million.

The Company had state income tax NOL carryforwards of $388.7 million and $377.7 million in 2019 and 2018 , respectively, in various states and foreign NOL carryforwards of $63.2 million and $56.9 million in 2019 and 2018 , respectively, in various foreign jurisdictions. As of December 31, 2019 , the Company had foreign tax credits of $0.6 million . The Company’s state NOL carryforwards expire from 2024 to 2039 , and the foreign NOL carryforwards have unlimited carryforward periods. After considering all available evidence in assessing the need for the valuation allowance, the Company believes that it is more likely than not the benefit from certain foreign and state deferred tax assets will not be realized. As of December 31, 2019 , the Company has provided a valuation allowance of $19.7 million with respect to the state deferred tax assets and $21.8 million valuation allowance with respect to the foreign deferred tax assets included in the table above, made up of $19.9 million related to Aeróleo, $1.3 million related to Sicher, and $0.6 million related to foreign tax credits. If the assumptions change and the Company determines it will be able to realize those deferred tax assets, the tax benefits relating to any reversal of the valuation allowance on deferred tax assets would be recorded in the income tax provision in the period in which such adjustments are identified. The Company’s operations are subject to the jurisdiction of multiple tax authorities, which impose various types of taxes on it including income taxes. Determining taxes owed in any jurisdiction requires the interpretation of relevant tax laws, regulations, judicial decisions and administrative interpretation of the local tax authority. As a result, the Company is subject to tax assessments in such jurisdictions including the re-determination of taxable amounts by tax authorities that may not agree with the Company’s interpretations and positions taken. The examination of the Company’s 2015 federal income tax return concluded with no adjustments during 2019 . Pursuant to ASC 740-35-25, the Company asserts permanent reinvestment on its controlled foreign corporations within Brazil, Colombia, and the British Virgin Islands. The effects of a tax position are recognized in the period in which it is determined that it is more likely than not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The Company remains subject to examination for U.S. federal and multiple state tax jurisdictions for tax years after 2015 and in Brazil for 2015 and subsequent years. Pursuant to a shareholders’ agreement entered into on October 1, 2015 with the Company’s partner in Aeróleo (see Note 5), the Company is the primary beneficiary, and Aeróleo became a consolidated entity. The Company has analyzed filing positions of Aeróleo in Brazil where it is required to file income tax returns for all open tax years (2014 to 2019). A reconciliation of the beginning and ending amount of the gross unrecognized tax benefits, excluding interest and penalties, is as follows (in thousands): 2019 2018 2017 Unrecognized tax benefits at the beginning of the year $ 11 $ 11 $ 261 Reductions due to settlements with taxing authorities — — (250 ) Unrecognized tax benefits at the end of the year $ 11 $ 11 $ 11 Amounts accrued for interest and penalties associated with unrecognized income tax benefits are included in other expense on the Consolidated Statements of Operations. As of December 31, 2019 , the gross amount of liability for accrued interest and penalties related to unrecognized tax benefits was $0.1 million . While amounts could change in the next twelve months, the Company does not anticipate such changes having a material impact on its financial statements. A reconciliation of the beginning and ending amount of the valuation allowance is as follows (in thousands): 2019 2018 2017 Valuation allowance at the beginning of the year $ 37,869 $ 34,967 $ 21,575 Increases to state valuation allowance 1,616 50 10,010 Increases due to foreign valuation allowances 2,007 2,852 7,578 Decrease due to Brazilian PERT Program — — (4,196 ) Valuation allowance at the end of the period $ 41,492 $ 37,869 $ 34,967 During the fourth quarter of 2017, Aeróleo elected to enter certain settled and open tax claims in the Tax Special Regularization Program (the “PERT Program”) pursuant to Brazil Provisional Measure No. 783 issued on May 31, 2017. The PERT Program allows for the partial settling of debts, both income tax debts and non-income-based tax debts, due by April 30, 2017 to Brazil’s Federal Revenue Service with the use of tax credits, including income tax loss carryforwards. A utilization of $3.5 million income tax benefit was recorded during the fourth quarter attributable to income tax loss carryforwards under the PERT Program partially offset by the accrual of operating expense associated with certain indirect tax claims enrolled into the PERT program.

On December 7, 2012, Era Group issued $200.0 million in aggregate principal amount of its 7.750% senior unsecured notes due December 15, 2022 (the “ 7.750% Senior Notes”) and received net proceeds of $191.9 million . Interest on the 7.750% Senior Notes is payable semi-annually in arrears on June 15 and December 15 of each year. The 7.750% Senior Notes may be redeemed at any time and from time to time at the applicable redemption prices set forth in the indenture governing the 7.750% Senior Notes, plus accrued and unpaid interest, if any, to the redemption date. The indenture governing the 7.750% Senior Notes contains covenants that restrict Era Group’s ability to, among other things, incur additional indebtedness, pay dividends or make other distributions or repurchase or redeem its capital stock, prepay, redeem or repurchase certain debt, make loans and investments, sell assets, incur liens, enter into transactions with affiliates, enter into agreements restricting its subsidiaries’ ability to pay dividends, and consolidate, merge or sell all or substantially all of the Company’s assets. In addition, upon a specified change of control trigger event or specified asset sale, Era Group may be required to repurchase the 7.750% Senior Notes. Era Group’s payment obligations under the 7.750% Senior Notes are fully and unconditionally guaranteed by all of its wholly-owned existing U.S. subsidiaries that are guarantors under the Revolving Credit Facility. The net proceeds of the offering were used to repay $190.0 million of borrowings outstanding under the Company’s prior $200.0 million senior secured revolving credit facility (the “Prior Credit Facility”). During the year ended December 31, 2019, the Company repurchased $0.7 million of the 7.750% Senior Notes at par for total cash of $0.7 million , including accrued interest of less than $0.1 million , and recognized a loss on debt extinguishment of less than $0.1 million . Revolving Credit Facility. On March 31, 2014, Era Group entered into the Revolving Credit Facility through an amendment to the Prior Credit Facility. Advances under the Revolving Credit Facility at the closing were used to refinance indebtedness incurred under the Prior Credit Facility. On March 7, 2018, Era Group entered into a Consent and Amendment No. 4 to the Amended and Restated Senior Secured Revolving Credit Facility Agreement (the “Amendment No. 4” and the Amended and Restated Revolving Credit Facility, as amended by Amendment No. 4, is referred to herein as the “Revolving Credit Facility”) that, among other things, (a) reduced the aggregate principal amount of revolving loan commitments from $200.0 million to $125.0 million , (b) extended the agreement’s maturity until March 31, 2021, (c) revised the definition of EBITDA to permit an add-back for certain litigation expenses related to the H225 helicopters, and (d) adjusted the maintenance covenant requirements to maintain an interest coverage ratio of not less than 1.75 :1.00 and a senior secured leverage ratio of not more than 3.25 :1.00. The applicable margin is based on the Company’s ratio of funded debt to EBITDA and increased by 50 basis points at each tier from the previous amendment. The Revolving Credit Facility provides the Company with the ability to borrow up to $125.0 million with a sub-limit of up to $50.0 million for letters of credit and includes an “accordion” feature which, if exercised and subject to agreement by the lenders and the satisfaction of certain conditions, would increase total commitments by up to $50.0 million . Availability under the Revolving Credit Facility may be limited by the terms of the 7.750% Senior Notes. The Revolving Credit Facility matures in March 2021. Borrowings under the Revolving Credit Facility bear interest at a rate per annum equal to, at Era Group’s election, either a base rate or LIBOR, each as defined, plus an applicable margin. The applicable margin is based on the Company’s ratio of funded debt to EBITDA, as defined, and ranges from 1.25% to 2.5% on the base rate margin and 2.25% to 3.5% on the LIBOR margin. The applicable margin as of December 31, 2019 was 1.75% on the “base rate” margin and 2.75% on the LIBOR margin. In addition, Era Group is required to pay a quarterly commitment fee based on the average unfunded portion of the committed amount at a rate based on the Company’s ratio of funded debt to EBITDA, as defined, that ranges from 0.375% to 0.5% . As of December 31, 2019 , the commitment fee was 0.5% . The obligations under the Revolving Credit Facility are secured by a portion of the Company’s helicopter fleet and other tangible assets and are guaranteed by Era Group’s wholly-owned U.S. subsidiaries. The Revolving Credit Facility contains various restrictive covenants including that the Company maintains a maximum senior secured leverage ratio, as defined, a minimum interest coverage ratio and a minimum ratio of the sum of the fair market value of mortgaged helicopters, accounts receivable and inventory to committed amounts under the Revolving Credit Facility as well as other customary covenants including certain restrictions on the Company’s ability to enter into certain transactions, including those that could result in the incurrence of additional indebtedness and liens, the making of loans, guarantees or investments, sales of assets, payments of dividends or repurchases of capital stock, and entering into transactions with affiliates. As of December 31, 2019 , the Company is in compliance with all debt covenants. As of December 31, 2019 , Era Group had no outstanding borrowings under the Revolving Credit Facility, and the remaining availability was $124.3 million based on the borrowing base of such date, net of issued letters of credit of $0.7 million . The availability under the Revolving Credit Facility is subject to the Company’s ability to maintain compliance with the financial ratios discussed above. In connection with Amendment No. 4 to the Revolving Credit Facility, which reduced the total commitment amount of the facility to $125.0 million , Era Group wrote off previously incurred debt issuance costs of $0.4 million and incurred additional debt issuance costs of $1.3 million in the year ended December 31, 2018. The additional debt issuance costs are included in other assets on the consolidated balance sheets and are amortized to interest expense in the consolidated statements of operations over the life of the Revolving Credit Facility. Promissory Notes . On December 23, 2010, the Company entered into a promissory note for $27.0 million to purchase a heavy helicopter. Upon maturity of the note on December 20, 2015, the Company refinanced the then outstanding balance of $19.0 million . The new note is secured by a helicopter and bears interest at the one-month LIBOR rate plus 1.81% . The interest rate resets monthly and at December 31, 2019 was 3.50% . The note requires monthly principal and interest payments of $0.1 million with a final payment of $12.8 million due in December 2020. On November 24, 2010, the Company entered into a promissory note for $11.7 million to purchase a medium helicopter.

The note requires monthly principal and interest payments of less than $0.1 million with a final payment of $4.0 million due in December 2020. During the year ended December 31, 2018, the Company amended the promissory notes to remove one helicopter and add two helicopters for a total of three helicopters providing cross-collateralization such that each helicopter now secures both promissory notes. Aeróleo Debt . During the year ended December 31, 2017, the Company settled certain tax disputes in Brazil totaling $3.0 million under the PERT Program and has agreed to make installment payments on the amounts due to the applicable taxing authorities.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES The Company’s unfunded capital commitments as of December 31, 2019 consisted primarily of agreements to purchase helicopters and totaled $80.5 million , of which $69.5 million is payable in 2020 with the balance payable through 2021 . The Company also had $1.3 million of deposits paid on options not yet exercised. The Company may terminate all of its total commitments, inclusive of deposits paid on options not yet exercised, without further liability other than liquidated damages of $2.1 million in the aggregate. Brazilian Tax Disputes In connection with its ownership of Aeróleo and its operations in Brazil, the Company has several ongoing legal disputes related to the local, municipal and federal taxation requirements in Brazil, including assessments associated with the import and re-export of its helicopters in Brazil. The legal disputes are related to: (i) municipal tax assessments arising under the authorities in Rio de Janeiro (for the period between 2000 and 2005) and Macaé (for the period between 2001 to 2006) (collectively, the “Municipal Tax Disputes”); (ii) social security contributions that one of its customers was required to remit from 1995 to 1998; (iii) penalties assessed due to its alleged failure to comply with certain deadlines related to the helicopters the Company imports and exports in and out of Brazil; and (iv) fines sought by taxing authorities in Brazil related to its use of certain tax credits used to offset certain social tax liabilities (collectively, the “Tax Disputes”). The aggregate amount at issue for the Tax Disputes is $13.8 million . The Municipal Tax Disputes represent the largest claims with a total amount being sought from Aeróleo, with approximately $10.3 million at issue. In addition to the Tax Disputes (and unrelated thereto), Aeróleo is engaged in two additional civil litigation matters relating to: (i) a dispute with its former tax consultant who has alleged that $0.5 million is due and payable as a contingency fee related to execution of certain tax strategies; and (ii) a fatal accident that occurred in 1983 and was previously settled with the plaintiffs’ in the U.S. (the “Civil Disputes”). With respect to the fatal accident, the plaintiffs are seeking to collect additional amounts in Brazil despite the previous settlement agreed upon by the parties in the U.S. The Company continues to evaluate and assess various legal strategies for each of the Tax Disputes and the Civil Disputes. As is customary for certain legal matters in Brazil, Aeróleo has already deposited amounts as security into an escrow account to pursue further legal appeals in several of the Tax Disputes and the Civil Disputes. As of December 31, 2019 , the Company has deposited $5.0 million into escrow accounts controlled by the court with respect to the Tax Disputes and the Civil Disputes, and the Company has fully reserved such amounts subject to final determination and the judicial release of such escrow deposits. These estimates are based on its assessment of the nature of these matters, their progress toward resolution, the advice of legal counsel and outside experts as well as management’s intentions and experience. Aeróleo plans to defend the cases vigorously. As of December 31, 2019 , it is not possible to determine the outcome of the Tax Disputes or the Civil Disputes, but the Company does not expect that an outcome would have a material adverse effect on its business, financial position or results of operations. General Litigation and Disputes In the normal course of business, the Company is involved in various litigation matters including, among other things, claims by third parties for alleged property damages and personal injuries. In addition, from time to time, the Company is involved in tax and other disputes with various government agencies. Management has used estimates in determining the Company’s potential exposure to these matters and has recorded reserves in its financial statements related thereto as appropriate. It is possible that a change in its estimates related to these exposures could occur, but the Company does not expect such changes in estimated costs would have a material effect on its business, consolidated financial position or results of operations.

Revenue from Contract with Customer [Abstract]
REVENUES	REVENUES The Company derives its revenues primarily from oil and gas flight services, emergency response services and dry-leasing activities. The adoption of ASC 606 pertains to the Company’s operating revenues. Dry-leasing revenues are recognized in accordance with ASC 842. Revenue is recognized when control of the promised goods or services is transferred 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 following table presents the Company’s operating revenues disaggregated by geographical region in which services are provided: 2019 2018 2017 Operating revenues: United States $ 146,952 $ 153,394 $ 150,583 Foreign 63,083 56,800 64,344 Total operating revenues $ 210,035 $ 210,194 $ 214,927 The following table presents the Company’s revenues earned by service line: 2019 2018 2017 Revenues: Oil and gas flight services: U.S. $ 139,312 $ 143,654 $ 134,010 International 56,510 56,800 64,344 Total oil and gas 195,822 200,454 198,354 Emergency response services 14,213 9,740 11,502 Flightseeing — — 5,071 Total operating revenues $ 210,035 $ 210,194 $ 214,927 Dry-leasing revenues: U.S. 2,562 3,873 1,604 International 13,462 7,609 14,790 Total revenues $ 226,059 $ 221,676 $ 231,321 The Company determines revenue recognition by applying the following steps: 1. Identify the contract with a customer; 2. Identify the performance obligations in the contract; 3. Determine the transaction price; 4. Allocate the transaction price to the performance obligations; and 5. Recognize revenue as the performance obligations are satisfied. The Company earns the majority of its revenue through master service agreements or subscription agreements, which typically include a fixed monthly or daily fee, incremental fees based on hours flown and fees for ancillary items such as fuel, security, charter services, etc. The Company’s arrangements to serve its customers represent a promise to stand-ready to provide services at the customer’s discretion. The Company recognizes revenue for flight services and emergency response services with the passing of each day as the Company has the right to consideration from its customers in an amount that corresponds directly with the value to the customer of performance completed to date. Therefore, the Company has elected to exercise the right to invoice practical expedient in its adoption of ASC 606. The right to invoice represents a method for recognizing revenue over time using the output measure of “value to the customer” which is an objective measure of an entity’s performance in a contract. The Company typically invoices customers on a monthly basis for revenues earned during the prior month, with payment terms of 30 days. The Company’s customer arrangements do not contain any significant financing component for customers. Amounts for taxes collected from customers and remitted to governmental authorities are reported on a net basis. Practical Expedients and Exemptions The Company does not incur any material incremental costs to obtain or fulfill customer contracts that require capitalization under the new revenue standard and has elected the practical expedient afforded by the new revenue standard to expense such costs as incurred upon adoption. These costs are included as operating expenses in the consolidated statements of operations. The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which it recognizes revenue at the amount to which it has the right to invoice for services performed.

NATURE OF OPERATIONS AND ACCO_2

NATURE OF OPERATIONS AND ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2019
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Consolidation	Basis of Consolidation . The consolidated financial statements include the accounts of Era Group Inc., its wholly-owned subsidiaries and entities that meet the criteria of VIEs of which the Company is the primary beneficiary. All significant intercompany accounts and transactions are eliminated in consolidation. The Company employs the equity method of accounting for investments in business ventures when it has the ability to exercise significant influence over the operating and financial policies of the ventures. The Company reports such investments in the accompanying consolidated balance sheets as equity investments and advances. The Company reports its share of earnings or losses of equity investees in the accompanying consolidated statements of operations as equity earnings (losses), net of tax.
Use of Estimates	Use of Estimates . The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Such estimates include, among other items, those related to allowance for doubtful accounts, useful lives of property and equipment, inventories, income tax provisions, impairments, fair values used in purchase price allocations and certain accrued and contingent liabilities. Actual results could differ from those estimates and those differences may be material.
Reclassifications	Reclassification. Certain amounts reported for prior periods in the consolidated financial statements have been reclassified to conform with the current period’s presentation.
Cash Equivalents	Cash Equivalents . The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Cash equivalents consist of overnight investments.
Trade Receivables	Trade Receivables . Customers are primarily international, independent and major integrated exploration, development and production companies, international helicopter operators and U.S. government agencies. Customers are typically granted credit on a short-term basis, and related credit risks are considered minimal. The Company routinely reviews its trade receivables and makes provisions for probable doubtful accounts; however, those provisions are estimates and actual results could differ from those estimates and those differences may be material. Trade receivables are deemed uncollectible and removed from accounts receivable and the allowance for doubtful accounts when collection efforts have been exhausted.
Concentrations of Credit Risk	Concentrations of Credit Risk . The Company is exposed to concentrations of credit risk relating to its receivables due from customers in the industries described above. The Company does not generally require collateral or other security to support its outstanding receivables. The Company minimizes its credit risk relating to receivables by performing ongoing credit evaluations. The Company is also exposed to concentrations of credit risk associated with cash and cash equivalents. The Company minimizes its credit risk relating to these positions by monitoring the financial condition of the financial institutions and counterparties involved and by primarily conducting business with large, well-established financial institutions and diversifying its counterparties.
Inventories	Inventories . Inventories are stated at the lower of average cost or net realizable value and consist primarily of spare parts and fuel. The Company establishes an allowance to accrue for the retirement of the cost of spare parts expected to be on hand at the end of a fleet’s life over the service lives of the related equipment, taking into account the estimated salvage value of the parts.
Property and Equipment	Property and Equipment . Property and equipment, stated at cost, is depreciated using the straight-line method over the estimated useful life of the asset to an estimated salvage value. With respect to helicopters, the estimated useful life is typically based upon a newly built asset being placed into service and represents the point at which it is typically not justifiable for the Company to continue to operate the asset in the same or similar manner. From time to time, the Company may acquire older assets that have already exceeded the Company’s useful life policy, in which case the Company depreciates such assets based on its best estimate of remaining useful life. The Company reviews the estimated useful lives and salvage values of its property and equipment on an ongoing basis for any changes in estimates. There were no such changes during the years ended December 31, 2019 , 2018 and 2017 . As of December 31, 2019 , the estimated useful life (in years) of the Company’s categories of new property and equipment was as follows: Helicopters (estimated salvage value at 40% of cost) 15 Machinery, equipment and spares 5 Buildings and leasehold improvements 10-30 Furniture, fixtures, vehicles and other 3-5 Equipment maintenance and repair costs and the costs of routine overhauls and inspections performed on helicopter engines and major components are charged to operating expense as incurred. Expenditures that extend the useful life or improve the marketing and commercial characteristics of equipment, as well as major improvements to other properties, are capitalized. The Company engages a number of third-party vendors to maintain the engines and certain components on some of its helicopter models under programs known as power-by-hour (“PBH”) maintenance contracts. These programs require the Company to pay for the maintenance service ratably over the contract period, typically based on actual flight hours. PBH providers generally bill monthly based on hours flown in the prior month, and the costs are expensed as incurred. In the event the Company places a helicopter in a program after a maintenance period has begun, it may be necessary to pay an initial buy-in charge based on hours flown since the previous maintenance event. The buy-in charge is normally recorded as a prepaid expense and amortized as an operating expense over the remaining PBH contract period. If a helicopter is sold or otherwise removed from a program before the scheduled maintenance work is carried out, the Company may be able to recover part of its payments to the PBH provider, in which case the Company records a reduction to operating expense. The Company also incurs repairs and maintenance expense through vendor arrangements whereby the Company obtains repair quotes and authorizes service through a repair order process. Under these arrangements, the Company records the repairs and maintenance cost as the work is completed. As a result, the timing of repairs and maintenance may result in operating expenses varying substantially when compared with a prior year or prior quarter if a disproportionate number of repairs, refurbishments or overhauls for components that are not covered under PBH arrangements are performed during a period. Certain interest costs incurred during the construction of equipment are capitalized as part of the assets’ carrying values and are amortized over such assets’ estimated useful lives.
Impairment	Impairment of Long-Lived Assets . The Company performs an impairment analysis on long-lived assets used in operations when events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. The Company’s long-lived assets are grouped at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of other groups of assets, which is generally at the fleet group level. If an impairment is indicated for the asset group classified as held and used, an impairment evaluation will be performed. Asset impairment evaluations are based on estimated undiscounted cash flows over the remaining useful life for the assets being evaluated. If the sum of the expected future cash flows is less than the carrying amount of the asset group, the Company would be required to recognize an impairment loss. During 2017, the Company concluded that the cash flows associated with its H225 heavy helicopters are largely independent from the cash flows associated with the remainder of the fleet and should be evaluated separately for impairment. The Company performed an impairment analysis on the H225 helicopters, capital parts and related inventory and determined that the projected undiscounted cash flows over the remaining useful life were less than the carrying amount. In determining the fair value, the Company used a cost approach, which begins with the replacement cost of a new asset and adjusts for age and functional and economic obsolescence. The inputs used in the Company’s fair value estimate were from Level 3 of the fair value hierarchy discussed in Note 2. As of December 31, 2019 , the Company recorded a $1.6 million impairment charge on its last remaining H225 helicopter. In 2018 and 2017 , the Company recorded a $1.0 million and $117.0 million impairment charge on its H225 helicopters, respectively. Impairment of Equity Investees . For equity investees held, the Company performs regular reviews of each investee’s financial condition, the business outlook for its products and services, and its present and projected results and cash flows. When an investee has experienced consistent declines in financial performance or difficulties in raising capital to continue operations, and when the Company expects the decline to be other-than-temporary, the investment is written down to fair value. Actual results may vary from estimates due to the uncertainty regarding the projected financial performance of investees, the severity and expected duration of declines in value and the available liquidity in the capital markets to support the continuing operations of the investees in which the Company has investments.
Intangible Assets	Intangible Assets . Intangible assets with indefinite lives are recorded during purchase price accounting in a business combination. The Company performs an annual impairment test of indefinite lived intangible assets and interim tests to the extent indicators of impairment develop between annual impairment tests. The Company’s impairment review process compares the fair value to the book value. To determine its fair value, the Company uses a discounted future cash flow approach that uses estimates including, among others, projected utilization of its fleet and contract rates. These estimates are reviewed each time the Company tests indefinite lived assets for impairment. While the Company believes its estimates and assumptions are reasonable, variations from those estimates could produce materially different results. Intangible assets with finite useful lives are amortized over their respective estimated useful lives. During the year ended December 31, 2019 the Company recorded a $1.0 million impairment charge on its indefinite lived intangible assets related to its subsidiary in Colombia. This amount is included in loss on impairment on the consolidated statement of operations.
Business Combinations	Business Combinations. The Company recognizes, with certain exceptions, 100 % of the fair value of assets acquired, liabilities assumed, and non controlling interests when the acquisition constitutes a change in control of the acquired entity. Shares issued in consideration for a business combination, contingent consideration arrangements and pre-acquisition loss and gain contingencies are all measured and recorded at their acquisition-date fair value. Subsequent changes to fair value of contingent consideration arrangements are generally reflected in earnings. Acquisition-related transaction costs are expensed as incurred, and any changes in an acquirer’s existing income tax valuation allowances and tax uncertainty accruals are recorded as an adjustment to income tax expense. The operating results of entities acquired are included in the accompanying consolidated statements of operations from the date of acquisition.
Deferred Financing Costs	Deferred Financing Costs. Deferred financing costs incurred in connection with the issuance of debt are amortized over the life of the related debt using the effective interest rate method for term loans and straight line method for revolving credit facilities. Amortization expense for deferred financing costs totaled $ 1.0 million , $1.4 million and $1.1 million during the years ended December 31, 2019 , 2018 and 2017 , respectively, including the write-off of $0.4 million of debt issuance costs in 2018, in connection with an amendment to the Company’s amended and restated senior secured revolving credit facility (the “Revolving Credit Facility”). Such amortization expense is included in interest expense in the consolidated statements of operations.
Revenue Recognition	Revenue Recognition . The Company recognizes revenues for flight services and emergency response services with the passing of each day as the Company has the right to consideration from its customers in an amount that corresponds directly with the value to the Company’s customer for the performance completed to date. Therefore, the Company has elected to exercise the right to invoice practical expedient in its adoption of ASC 606. The right to invoice represents a method for recognizing revenue over time using the output measure of “value to the customer” which is an objective measure of an entity’s performance in a contract. The Company typically invoices its customers on a monthly basis for revenues earned during the prior month with payment terms of 30 days. The Company’s customer arrangements do not contain any significant financing component for its customers.
Income Taxes	Income Taxes . Era Group and its majority-owned U.S. subsidiaries file a consolidated U.S. federal tax return. Era Group’s foreign consolidated subsidiaries each file tax returns in their applicable jurisdictions. Deferred income tax assets and liabilities have been provided in recognition of the income tax effect attributable to the book and tax basis differences of assets and liabilities reported in the accompanying consolidated financial statements. Deferred tax assets or liabilities are provided using the enacted tax rates expected to apply to taxable income in the periods in which they are expected to be settled or realized. Interest and penalties relating to uncertain tax positions are recognized in interest expense and administrative and general expense, respectively, in the accompanying consolidated statements of operations. The Company records a valuation allowance to reduce its deferred tax assets if it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company has evaluated the newly enacted global intangible low-taxed income (GILTI) provisions, which could subject its foreign earnings to a minimum level of tax and has decided to make an election to treat these costs as period costs.
Foreign Currency Transactions	Foreign Currency Transactions . The functional currency for each of the Company’s foreign entities is the U.S. dollar. From time to time, the Company enters into transactions denominated in currencies other than its functional currency. Gains and losses resulting from changes in currency exchange rates between the functional currency and the currency in which a transaction is denominated are included in foreign currency gains (losses), net in the accompanying consolidated statements of operations in the period which the currency exchange rates change.
Earnings (Loss) Per Common Share	Earnings (Loss) Per Common Share. Basic earnings (loss) per common share of the Company are computed based on the weighted average number of common shares issued and outstanding during the relevant periods. Diluted earnings (loss) per common share of the Company are computed based on the weighted average number of common shares issued and outstanding plus the effect of potentially dilutive securities through the application of the if-converted method and/or treasury method.
Savings Plan	Savings Plan. The Company provides a defined contribution plan (the “Savings Plan”) for its eligible U.S.-based employees. The Savings Plan provides for qualified, non-elective Company contributions in an amount equal to 3% of each employee’s eligible pay plus an amount equal to 100% of an employee’s first 3% of wages invested in the Savings Plan and immediate and full vesting in the Company’s contributions. The Savings Plan is subject to annual review by the Board of Directors of Era Group (the “Board of Directors”).
Recent Accounting Pronouncements	Recent Accounting Pronouncements. - Adopted. In February 2016, the FASB issued ASU No. 2016-02, “Leases” (ASU No. 2016-02), which establishes comprehensive accounting and financial reporting requirements for leasing arrangements. This ASU supersedes the existing requirements in FASB ASC Topic 840, “Leases,” and requires lessees to recognize substantially all lease assets and lease liabilities on the balance sheet. The provisions of this ASU also modified the definition of a lease and outline requirements for recognition, measurement, presentation and disclosure of leasing arrangements by both lessees and lessors. The ASU was effective for interim and annual periods beginning after December 15, 2018, and early adoption of the standard was permitted. Entities were required to adopt the ASU using a modified retrospective approach, subject to certain optional practical expedients, and apply the provisions of this ASU to leasing arrangements existing at or entered into after the earliest comparative period presented in the financial statements. In July 2018 this ASU was further amended by the provisions of ASU No. 2018-11, “Targeted Improvements” to Topic 842 whereby the FASB decided to provide an alternate transition method by allowing entities to initially apply the new leases standard at the adoption date (such as January 1, 2019, for calendar year-end public business entities) and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption consistent with preparers’ requests. The Company adopted the amended ASU No. 2018-11 effective January 1, 2019 using the current-period adjustment method, however upon adoption of the standard the Company determined that a cumulative-effect adjustment to the opening balance of retained earnings in that period was not required. The Company also elected an optional practical expedient to retain its former classification of leases, and as a result, the initial impact of adopting this new standard did not have a material impact to its consolidated financial statements. Additionally, the Company elected not to bifurcate and separately account for non lease components contained in a single contract. In August 2018, the FASB issued ASU No. 2018-15, “Intangibles-Goodwill and Other-Internal-Use Software” (Subtopic 350-40), providing guidance addressing a customer's accounting for implementation costs incurred in a cloud computing arrangement (“CCA”) that is considered a service contract. Under the new guidance, implementation costs for a CCA are evaluated for capitalization using the same approach as implementation costs associated with internal-use software and should be expensed over the term of the hosting arrangement, which includes any reasonably certain renewal periods. The new guidance is effective for fiscal years beginning after December 15, 2019 for calendar year-end public business entities. Early adoption is permitted, including adoption in any interim period. The Company will not take possession of implemented software and will rely on vendors to host the software, thus determining the cloud computing arrangements are service contracts. The Company adopted ASU No. 2016-13, effective January 1, 2019, and has appropriately accounted for the implementation costs of the cloud computing arrangements entered into in the first half of 2019. The adoption of ASU-2018-15 did not have a material impact on the Company’s consolidated financial statements. New Accounting Standards - Not Yet Adopted. In January 2020, the FASB issued ASU No. 2020-01, “Investments-Equity Securities” Topic 321, “Investments-Equity Method and Joint Ventures” Topic 323 and “Derivatives and Hedging” Topic 815 (ASU No. 2020-01) as an update to ASU No. 2016-01 “Financial Instruments-Overall”, further clarifying the interaction between the accounting for equity securities, equity method investments, and certain derivative instruments. This ASU clarifies that a company should consider observable transactions that require a company to either apply or discontinue the equity method of accounting under Topic 323, for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. With this update, the FASB aims to clarify that, when determining the accounting for certain forward contracts and purchased options a company should now consider, whether upon settlement or exercise, if the underlying securities would be accounted for under the equity method or fair value option. The FASB expects this ASU to reduce diversity in practice and increase comparability of the accounting for these interactions. This ASU is effective for interim and annual periods beginning after December 15, 2020. The Company is evaluating the potential impact of adopting this ASU but does not expect such adoption to have a material impact on its consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, “Measurement of Credit Losses on Financial Instruments” (ASU No. 2016-13), which sets forth the current expected credit loss model, a new forward-looking impairment model for certain financial instruments based on expected losses rather than incurred losses. The ASU is effective for interim and annual periods beginning after December 15, 2019, and early adoption of the standard is permitted. Entities are required to adopt this ASU using a modified retrospective approach, subject to certain limited exceptions. The Company has evaluated the potential impact of adopting this ASU and believes such adoption will not have a material impact on its consolidated financial statements. In August 2018, the FASB issued ASU-2018-13, “Fair Value Measurements” (ASU No. 2018-13, update to topic ASC-820), providing guidance for the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period, and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information (such as the median or arithmetic average) in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements. ASU-2018-13 will be effective for interim and annual periods beginning December 15, 2019. The Company has not adopted this ASU and believes such adoption will not have a material impact on its consolidated financial statements.
