EXPLANATORY NOTE
This Amended Quarterly Report on Form 10-Q/A is filed by Bristow Group Inc., which we refer to as “Bristow Group” or the “Company.”  We use the pronouns “we”, “our” and “us” and the term “Bristow Group” to refer collectively to Bristow Group and its consolidated subsidiaries and affiliates, unless the context indicates otherwise. We are filing this Amendment No. 1 (this “Amendment No. 1”) to our Quarterly Report on Form 10-Q for the quarter ended September 30, 2018, originally filed with the U.S. Securities and Exchange Commission (the “SEC”) on November 9, 2018 (the “Original Filing”), to (i) reflect a change in management’s assessment of our disclosure controls and procedures, (ii) revise the Company’s previously reported condensed consolidated financial statements to reclassify substantially all debt balances from long-term to short-term as explained in Notes 1 and 4 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report, (iii) include disclosures regarding the Company’s ability to continue as a going concern and for immaterial corrections to prior year financial information and (iv) include a revised report of KPMG LLP (“KPMG”), our Independent Registered Public Accounting Firm, with respect to its review of the condensed consolidated financial statements included herein.
As previously disclosed in the Company’s Current Report on Form 8-K filed with the SEC on February 11, 2019, management of the Company concluded that the Company did not have adequate monitoring control processes in place related to certain non-financial covenants within certain of its secured financing and lease agreements, and this control deficiency identified represents a “material weakness” in internal control over financial reporting. Accordingly, as discussed in that Current Report, the Company’s internal control over financial reporting was deemed ineffective at March 31, 2018 and the reporting periods thereafter, and management’s assessment and the report of KPMG on internal control over financial reporting as of March 31, 2018 should no longer be relied upon. As previously disclosed in the Company’s Current Report on Form 8-K filed with the SEC on May 7, 2019, in connection with the filing of this Amendment No. 1, applicable accounting rules required the Company to make an updated assessment as of the filing date of this Amendment No. 1 of whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern during the twelve months from the date of filing of this Amendment No. 1. This updated assessment is required to include an assessment of the Company’s ability to meet its operating and other contractual cash obligations, including aircraft and other capital purchase commitments and debt service requirements, using available liquidity (cash on hand, operating cash flow and other available cash sources) over the twelve-month period, commencing as of the filing date of this Amendment No. 1.
The Company’s liquidity outlook has recently changed and as a result of this updated assessment, the Company has concluded that disclosure should be included in this Amendment No. 1 to express substantial doubt about the Company’s ability to continue as a going concern based on recurring losses from operations and estimates of liquidity during the twelve months from the filing date of this Amendment No. 1 as well as the bankruptcy filings as further discussed below.
In addition, under certain of our secured equipment financings, we are required to deliver audited annual consolidated financial statements without a going concern qualification or explanation. On June 19, 2019, we filed an amendment to the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2018 (the “Amended 10-K”) with such a going concern qualification or explanation, and the revised report of KPMG on the consolidated financial statements included in the Amended 10-K included an explanatory paragraph expressing uncertainty as to the Company’s ability to continue as a going concern. As a result of the delivery of the Amended 10-K with a going concern qualification or explanation, an event of default exists under those secured equipment financings, giving those secured equipment lenders the right to accelerate repayment of the applicable debt, subject to Chapter 11 protections, and triggering cross-default and/or cross-acceleration provisions in substantially all of our other debt instruments should that right to accelerate repayment be exercised.
As a result of the facts and circumstances discussed above, the Company concluded that substantially all debt balances should be reclassified from long-term to short-term within the Amended 10-K and within this Amendment No. 1.
On May 11, 2019, the Company and its subsidiaries BHNA Holdings Inc., Bristow Alaska Inc., Bristow Helicopters Inc., Bristow U.S. Leasing LLC, Bristow U.S. LLC, BriLog Leasing Ltd. and Bristow Equipment Leasing Ltd. (together with the Company, the “Debtors”) filed voluntary petitions (the “Chapter 11 Cases”) in the United States Bankruptcy Court for the Southern District of Texas, Houston Division (the “Bankruptcy Court”) seeking relief under Chapter 11 of Title 11 of the United States Code (the “Bankruptcy Code”). The Debtors’ Chapter 11 Cases are jointly administered under the caption In re: Bristow Group Inc., et al., Main Case No. 19-32713. The Debtors continue to operate their businesses and manage their properties as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court. The commencement of the Chapter 11 Cases also constitutes an event of default under certain debt financings, giving those lenders the right to accelerate repayment of the applicable debt, subject to Chapter 11 protections.




Amendments
Based on the foregoing, revisions to the Original Filing have been made to the following items:
Part I, Item 1. Financial Statements;
the first paragraph of Part I, Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations; the first paragraph of “Executive Overview” in Part I, Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations; and the captions “Liquidity and Capital Resources — Future Cash Requirements — Contractual Obligations, Commercial Commitments and Off Balance Sheet Arrangements” and “Liquidity and Capital Resources — Financial Condition and Sources of Liquidity” and the other discussions surrounding liquidity in Part I, Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations;
Part I, Item 4. Controls and Procedures; and
Part II, Item 6. Exhibits.
As required by Rule 12b-15 under the Securities Act of 1934, as amended (the “Exchange Act”), this Amendment No. 1 contains new certifications (filed as Exhibits 31.3, 31.4, 32.3 and 32.4) by our Chief Executive Officer and Chief Financial Officer required pursuant to Rule 13a-14(a) under the Exchange Act and 18 U.S.C. Section 1350.  Accordingly, this Amendment No. 1 amends and restates Part II, Item 6. Exhibits to reflect the filing of these currently dated certifications.
In addition, this Amendment No. 1 contains a revised report of KPMG with respect to its review of the condensed consolidated financial statements included herein.  Accordingly, this Amendment No. 1 amends and restates Part I, Item 1 under the heading “Report of Independent Registered Public Accounting Firm” to reflect the revised results of KPMG’s review.
We have also updated the signature page and our unaudited condensed consolidated financial statements formatted in eXtensible Business Reporting Language (XBRL) in Exhibits 101.
Except as described above, this Amendment No. 1 does not amend, update or change any other items or disclosures contained in the Original Filing as amended by this Amendment No. 1, and accordingly, this Amendment No. 1 does not reflect or purport to reflect any information or events occurring after the original filing date or modify or update those disclosures affected by subsequent events. Accordingly, this Amendment No. 1 should be read in conjunction with the Original Filing and our other filings with the SEC subsequent to the Original Filing.
In connection with the Original Filing, we carried out an evaluation, under the supervision of and with the participation of our management, including Jonathan E. Baliff, our previous Chief Executive Officer (“Previous CEO”), and L. Don Miller, our previous Chief Financial Officer (“Previous CFO”), of the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) of the Exchange Act) as of September 30, 2018. Based on that evaluation, our Previous CEO and Previous CFO concluded that such disclosure controls and procedures were effective to ensure that information required to be disclosed in our periodic reports filed under the Exchange Act is recorded, processed, summarized and reported within the time periods specified by the SEC’s rules and forms and such information is accumulated and communicated to our management as appropriate to allow for timely decisions regarding required disclosure under the Exchange Act.
A discussion of the Company’s subsequent reevaluation of internal control over financial reporting, material weakness identified by the Company and the actions taken by management are set forth in Item 4. Controls and Procedures included herein.

BRISTOW GROUP INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)


Note 1 — BASIS OF PRESENTATION, CONSOLIDATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
The condensed consolidated financial statements include the accounts of Bristow Group Inc. and its consolidated entities (“Bristow Group”, the “Company”, “we”, “us”, or “our”) after elimination of all significant intercompany accounts and transactions. Our fiscal year ends March 31, and we refer to fiscal years based on the end of such period. Therefore, the fiscal year ending March 31, 2019 is referred to as “fiscal year 2019”2019. Pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”(“SEC”), the information contained in the following notes to condensed consolidated financial statements is condensed from that which would appear in the annual consolidated financial statements; accordingly, the condensed consolidated financial statements included herein should be read in conjunction with the consolidated financial statements and related notes thereto contained in the Company’sour fiscal year 2018 Annual Report on Form 10-K for the fiscal year ended March 31, 2018, as amended by the amendment thereto (the “Amended 10-K”), filed with the SEC on June 19, 2019 (the “fiscal year 2018 Financial Statements”). Operating results for the interim period presented are not necessarily indicative of the results that may be expected for the entire fiscal year.
The condensed consolidated financial statements included herein are unaudited; however, they include all adjustments of a normal recurring nature which, in the opinion of management, are necessary for a fair presentation of the consolidated balance sheet of the Company as of September 30,December 31, 2018, the consolidated statements of operations and comprehensive loss for the three and sixnine months ended September 30,December 31, 2018 and 2017, the consolidated cash flows for the sixnine months ended September 30,December 31, 2018 and 2017, and the consolidated statements of changes in stockholders’ investment for the three and sixnine months ended September 30,December 31, 2018.
Bankruptcy, Restructuring Support Agreement and Going Concern
The Company’s liquidity outlook has recently changed since the date of the Company’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2018, originally filed with the SEC on November 9, 2018 (the “Original Filing”), resulting in substantial doubt about the Company’s ability to continue as a going concern. In connection with the filing of this Amendment No. 1 (this “Amendment No. 1”) to the Original Filing, applicable accounting rules required the Company to make an updated assessment as to whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern during the twelve months from the date of filing of this Amendment No. 1. This updated assessment included an assessment of the Company’s ability to meet its operating and other contractual cash obligations, including aircraft and other capital purchase commitments and debt service requirements, using available liquidity (cash on hand, operating cash flow and other available cash sources) over the twelve-month period commencing as of the date of the filing of this Amendment No. 1. As a result of this updated assessment, the Company concluded that disclosure should be included in this Amendment No. 1 to express substantial doubt about the Company’s ability to continue as a going concern based on recurring losses from operations and estimates of liquidity during the twelve months from the filing date of this Amendment No. 1 as well as the bankruptcy filings as further discussed below. The delivery of the Amended 10-K with a going concern qualification or explanation constituted an event of default under certain of our secured equipment financings, giving those secured equipment lenders the right to accelerate repayment of the applicable debt, subject to Chapter 11 protections, and triggering cross-default and/or cross-acceleration provisions in substantially all of our other debt instruments should that right to accelerate repayment be exercised.
As a result of the facts and circumstances discussed above, the Company concluded that substantially all debt balances of approximately $1.4 billion should be reclassified from long-term to short-term as of March 31, 2018 within the Amended 10-K and as of September 30, 2018 within this Amendment No. 1 on our condensed consolidated balance sheet.
As discussed in the Explanatory Note included elsewhere in this Quarterly Report, onOn May 11, 2019 (the “Petition Date”), Bristow Group Inc. and its subsidiaries BHNA Holdings Inc., Bristow Alaska Inc., Bristow Helicopters Inc., Bristow U.S. Leasing LLC, Bristow U.S. LLC, BriLog Leasing Ltd. and Bristow Equipment Leasing Ltd. (together, the “Debtors”) filed voluntary petitions (the “Chapter 11 Cases”) in the United States Bankruptcy Court for the Southern District of Texas, Houston Division (the “Bankruptcy Court”) seeking relief under Chapter 11 of Title 11 of the United States Code (the “Bankruptcy Code”). The Debtors’ Chapter 11 Cases are jointly administered under the caption In re: Bristow Group Inc., et al., Main Case No. 19-32713. The Debtors continue to operate their businesses and manage their properties as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court. The commencement of the Chapter 11 Cases also constitutes an event of default under certain debt financings, giving those lenders the right to accelerate repayment of the applicable debt, subject to Chapter 11 protections.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
(Unaudited)


As previously disclosed in the Company’s Current Report on Form 8-K filed with the SEC onOn May 13,10, 2019, we entered into a restructuring support agreement (the “RSA”) on May 10, 2019 with (i) certain holders (the “Supporting Secured Noteholders”) of the Company’s 8.75% Senior Secured Notes due 2023 (the “8.75% Senior Secured Notes”) and (ii) the guarantors of the 8.75% Senior Secured Notes, to support a restructuring of the Company (the “Restructuring”) on the terms set forth in the term sheet contained in an exhibit to the RSA (the “Restructuring Term Sheet”). The RSA contemplates the filing of the Chapter 11 Cases to implement the Restructuring pursuant to a Chapter 11 plan of reorganization (the “Plan”) and the various related transactions set forth in or contemplated by the Restructuring Term Sheet, the DIP Term Sheet (as defined herein) and the other restructuring documents attached to the RSA.
The RSA contains certain covenants on the part of each of the Company and the Supporting Secured Noteholders, including limitations on the Supporting Secured Noteholders’ ability to pursue alternative transactions, commitments by the Supporting Secured Noteholders to vote in favor of the Plan and commitments of the Company and the Supporting Secured Noteholders to negotiate in good faith to finalize the documents and agreements governing the Plan. The RSA also provides for certain conditions to the obligations of the parties and for termination upon the occurrence of certain events, including without limitation, the failure to achieve certain milestones and certain breaches by the parties under the RSA.
Also as previously disclosed in the Company’s Current Report on Form 8-K filed with the SEC on May 13, 2019,in connection with the Chapter 11 Cases and pursuant to a Commitment Letter, dated May 10, 2019, from the lenders party thereto and agreed to by the Company and Bristow Holdings Company Ltd. III (together, the “DIP Borrowers”), an ad hoc group of holders of the 8.75% Senior Secured Notes has agreed to provide the DIP Borrowers with a superpriority senior secured debtor-in-possession credit facility (the “DIP Facility”) on the terms set forth in the DIP Facility Term Sheet attached thereto (the “DIP Term Sheet”). The DIP Term Sheet provides that, among other things, the DIP Facility shall be comprised of loans in an aggregate principal amount of $75.0 million. The availability of the DIP Facility is subject to certain conditions and milestone, including approval by the Bankruptcy Court, which has not been obtained at this time.
The Company expects to continue operations in the normal course during the pendency of the Chapter 11 Cases.
The condensed consolidated financial statements included herein have been prepared on a going concern basis of accounting, which contemplates continuity of operations, realization of assets, and satisfaction of liabilities and commitments in the normal course of business. The condensed consolidated financial statements do not include any adjustments that might result from the outcome of the substantial doubt as to the Company’s ability to continue as a going concern. Our ability to continue as a going concern is also contingent upon our ability to comply with the financial and other covenants contained in the Term Loan Credit Agreement entered into on May 10, 2019 (as previously disclosed in the Company’s Current Report on Form 8-K filed with the SEC on May 13, 2019) and our ability to successfully develop and, subject to the Bankruptcy Court’s approval, implement the Plan, among other factors.

Immaterial Corrections to Prior Period Financial Information
The consolidated balance sheet and statement of changes in stockholders’ equity included in this Amendment No. 1 reflect immaterial adjustments to the historical balances in retained earnings and accrued wages, benefits and related taxes as of September 30 and March 31, 2018. We made these adjustments in accordance with GAAP, to reflect additional liability related to a vacation accrual for employees in Norway. The adjustment stems from our initial purchase price accounting for the Bristow Norway acquisition in October 2008 and subsequent accounting for employee vacation liability. We evaluated the materiality of the error from both a quantitative and qualitative perspective and concluded that the error was immaterial to our prior period interim and annual consolidated financial statements. Since the revision was not material to any prior period interim or annual consolidated financial statements, no amendments to previously filed interim or annual periodic reports were required. Consequently, we revised the historical consolidated financial information presented herein. Given the historical nature of the adjustment, we recorded a correction within the consolidated statements of stockholders’ investment and redeemable noncontrolling interest to retained earnings as of September 30 and March 31, 2018 of $4.9 million. In addition, below are amounts as reported and as adjusted for each year presented in our condensed consolidated financial statements included in this filing (in thousands):

Includes impairment of $87.5 million for H225 aircraft and $17.5 million for Eastern Airways International Limited (“Eastern Airways”) aircraft and equipment.
Prior to the three months ended September 30, 2018, we had been actively marketing our H225 aircraft with the expectation of a substantial return of the aircraft to oil and gas service. However, market conditions and more significantly, the recent development of alternative opportunities outside of our traditional oil and gas service for our H225 aircraft and our decision to pursue those opportunities during the three months ended September 30, 2018, indicateindicated a substantial return to oil and gas service within our operations iswas not likely. Therefore, during the three months ended September 30, 2018, we concluded that cash flows associated with our H225 helicopters arewere largely independent from the cash flows associated with the remainder of our oil and gas related property and equipment (“oil and gas asset group”) and should be tested for impairment as a stand-alone asset group. In accordance with Accounting Standard Codification (“ASC”) 360-10, we performed an impairment analysis for our stand-alone H225 asset group and determined that the forecasted cash flows over the remaining useful life of the asset group were insufficient to recover the carrying value of the asset group. We determined the fair value of the H225 asset group to be $116.4 million and recorded an impairment charge of $87.5 million. In addition, we performed a review of our H225 aircraft related inventory and recorded an

impairment charge of $8.9 million to record the inventory at the lower of cost or net realizable value. These impairments are included in our Corporate and other region in Note 11.12. The inputs used in our fair value estimates were from Level 3 of the fair value hierarchy discussed in Note 5.6.
  The removal of the H225 aircraft from our oil and gas asset group and changes in our forecasted cash flows for that asset group during the three months ended September 30, 2018 indicated the need for the performance of a recoverability analysis of the oil and gas asset group. In accordance with Accounting Standard CodificationASC 360-10, we estimate future undiscounted cash flows to test the recoverability of our oil and gas asset group, which largely consists of our oil and gas related held for use aircraft. The determination of estimated future undiscounted cash flows required us to use significant unobservable inputs, including assumptions related to projected demand for services, rates and anticipated aircraft disposal values. We determined that the estimated future undiscounted cash flows exceeded the carrying value for our oil and gas asset group as of September 30, 2018, and no impairment was recorded on these assets. Future declines in operating performance, aircraft disposal values, anticipated business outlook, or projected aircraft deliveries currently accounted for as construction in progress may reduce our estimated future undiscounted cash flows and result in impairment of our oil and gas asset group.
  In addition, changes in our forecasted cash flows during the three months ended September 30, 2018 indicated the need for the performance of a recoverability analysis for the airline related assets of Eastern Airways. In accordance with Accounting Standard CodificationASC 360-10, we estimate future undiscounted cash flows to test the recoverability of the airline related assets of Eastern Airways for potential impairment. The determination of estimated future undiscounted cash flows required us to use significant unobservable inputs, including assumptions related to projected demand for services and rates. We determined that the estimated future undiscounted cash flows were below the carrying value for our airline related assets of Eastern Airways as of September 30, 2018.  We determined the fair value of the asset group to be $20.5 million and recorded an impairment charge of $17.5 million.  As part of our impairment review of the airline assets of Eastern Airways, we also recorded impairments of $3.0 million related to the remaining intangible assets and $0.3 million related to inventory. These impairments are included in our Europe and Caspian region in Note 11.12. The inputs used in our fair value estimates were from Level 3 of the fair value hierarchy discussed in Note 5.6.
No further triggers to review our assets for impairment exist as of December 31, 2018.
During the sixnine months ended September 30,December 31, 2017, as a result of changes in expected future utilization of aircraft within our training fleet we recorded a $1.2 million charge to impair inventory used on our training fleet, which is included in loss on impairment on our condensed consolidated statement of operations. This impairment is included in our Corporate and other region in Note 11.

Inventories
As of September 30December 31 and March 31, 2018, inventories were net of allowances of $22.4$21.1 million and $26.0 million, respectively. As discussed above in Loss on Impairment, we performed a review of our H225 aircraft related inventory and Eastern Airways inventory and recorded impairment charges of $8.9 million and $0.3 million, respectively, to record the inventories at the lower of cost or net realizable value during the threenine months ended September 30,December 31, 2018. During the sixnine months ended September 30,December 31, 2017, as a result of changes in expected future utilization of aircraft within our training fleet, we recorded a $1.2 million charge to impair inventory used on our training fleet, which is included in loss on impairment on our condensed consolidated statement of operations. These impairment charges are not reflected in the allowances above.
Prepaid Expenses and Other Current Assets
As of September 30December 31 and March 31, 2018, prepaid expenses and other current assets included the short-term portion of contract acquisition and pre-operating costs totaling $9.9$9.6 million and $10.8 million, respectively, related to the search and rescue (“SAR”) contracts in the U.K. and two customer contracts in Norway, which are recoverable under the contracts and will be expensed over the terms of the contracts. For the three months ended September 30,December 31, 2018 and 2017, we expensed $2.5$2.4 million and $2.8 million, respectively, and for the sixnine months ended September 30,December 31, 2018 and 2017, we expensed $5.2$7.6 million and $5.7$8.5 million, respectively, related to these contracts.
Goodwill
Goodwill is recorded when the cost of acquired businesses exceeds the fair value of the identifiable net assets acquired. Goodwill has an indefinite useful life and is not amortized, but is assessed for impairment annually or when events or changes in circumstances indicate that a potential impairment exists.
Goodwill of $18.8$18.3 million and $19.9 million as of September 30December 31 and March 31, 2018, respectively, related to our Asia Pacific reporting unit was as follows (in thousands):

During fiscal year 2018, we reached agreements with original equipment manufacturers (“OEM”) to recover approximately $136.0 million related to ongoing aircraft issues, of which $125.0 million was realized during fiscal year 2018 and $11.0 million was recovered during the sixnine months ended September 30,December 31, 2018. To reflect the amount realized from these OEM cost recoveries during fiscal year 2018, we recorded a $94.5 million decrease in the carrying value of certain aircraft in our fleet through a decrease in property and equipment – at cost, reduced rent expense by $16.6 million and recorded a deferred liability of $13.9 million,

included in other accrued liabilities and other liabilities and deferred credits, related to a reduction in rent expense to be recorded in future periods, of which $2.4$1.0 million and $5.9$6.9 million was recognized during the three and sixnine months ended September 30,December 31, 2018, respectively. We determined the realized portion of the cost recoveries related to a long-term performance issue with the aircraft, requiring a reduction of carrying value for owned aircraft and a reduction in rent expense for leased aircraft. For the owned aircraft, we allocated the $94.5 million as a reduction in carrying value by reducing the historical acquisition value of each affected

(Unaudited)


aircraft on a pro-rata basis utilizing the historical acquisition value of the aircraft. For the leased aircraft, we will recognize the remaining deferred liability of $8.0$7.0 million as a reduction in rent expense prospectively on a straight-line basis over the remaining lease terms. This will result in a reduction to rent expense of $2.0$1.0 million during the remainder of fiscal yearthree months ending March 31, 2019, $4.0 million during fiscal year 2020 and $2.0 million during fiscal year 2021.
During the sixnine months ended September 30,December 31, 2018, we recovered the remaining $11.0 million in OEM cost recoveries by agreeing to net certain amounts previously accrued for aircraft leases and capital expenditures against those recoveries. During the sixnine months ended September 30,December 31, 2018, we recorded a $7.6 million increase in revenue and a $2.1$3.1 million decrease in direct cost. We expect to realize the remaining $1.3$0.3 million recovery during fiscal year 2019 as follows: $1.0 milliona decrease in direct cost in the three months ended December 31, 2018, and $0.3 million decrease in direct cost in the three months endedending March 31, 2019. The increase in revenue relates to compensation for lost revenue in prior periods from the late delivery of aircraft and the decreases in direct cost over fiscal year 2019 relate to prior costs we have incurred and future costs we expect to incur.
In connection with the $87.5 million impairment of our H225 aircraft, we revised our salvage values for each H225 aircraft.  In accordance with accounting standards, we will recognize the change in depreciation due to the reduction in carrying value and revision of salvage values on a prospective basis over the remaining life of the aircraft. This resulted in an additional $1.5 million of depreciation expense during the three and nine months ended December 31, 2018 and will result in an increase of depreciation expense of $3.0$1.5 million during the remainder of fiscal year 2019, $5.9 million during fiscal year 2020, $1.9 million during fiscal year 2021 and a reduction of $10.3 million during fiscal year 2022 and beyond.
As of December 31, 2018, we revised the salvage values of certain aircraft to reflect our expectation of future sales values given our disposal plans for those aircraft. We expect to record additional depreciation expense of $1.4 million during the remainder of fiscal year 2019 and $2.8 million during fiscal year 2020.
On November 1, 2017, we sold our 100% interest in Bristow Academy. As of September 30, 2017, we concluded the disposal group, comprised of the Bristow Academy assets and liabilities met the assets held for sale criteria under ASC 360, but did not meet the requirements for classification as discontinued operations. We evaluated the carrying value of the Bristow Academy disposal group and determined an impairment of $6.5 million, recorded within loss on disposal of assets on our condensed consolidated statement of operations, was necessary to record the disposal group at fair value based on the terms of the sale. The Bristow Academy disposal group is included in Corporate and other in Note 912 — Segment Information.

Recent Accounting Pronouncements
We consider the applicability and impact of all accounting standard updates (“ASUs”). ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial position or results of operations.
In May 2014, the Financial Accounting Standards Board (the “FASB”) issued accounting guidance on revenue recognition replacing the existing accounting standard and industry-specific guidance for revenue recognition with a five-step model for recognizing and measuring revenue from contracts with customers. The underlying principle of the new standard is to recognize revenue to depict the transfer of goods or services to customers at the amount expected to be collected. This new standard is effective for annual reporting periods beginning after December 15, 2017. We adopted the standard as of April 1, 2018 using the modified retrospective method applied to open contracts and only to the version of the contracts in effect as of April 1, 2018. Prior period amounts have not been adjusted and continue to be reflected in accordance with our historical accounting policy. There was no impact on our condensed consolidated financial statements and no cumulative effect adjustment was recognized. For further details, see Note 2.

3.
In February 2016, the FASB issued accounting guidance which amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting. This accounting guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, with early adoption permitted. Additionally, this accounting guidance requires a modified retrospective transition approach for all leases existing at, or entered into after the date of initial application, with an option to use certain transition relief. In July 2018, the FASB issued a practical expedient that would allow entities the option to apply the provisions of the new lease guidance at the effective date of adoption without adjusting the comparative periods presented. In December 2018, the FASB provided certain improvements to this topic that are narrow in scope. We have not yet adopted this standard and are currently evaluating the effect this standard will have on our financial statements.
In October 2016, the FASB issued accounting guidance related to current and deferred income taxes for intra-entity transfer of assets other than inventory. This accounting guidance requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs and eliminates the exception for an intra-entity transfer of an asset other than inventory. This accounting guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and early adoption is permitted. We adopted this accounting guidance effective April 1, 2018 using the modified retrospective method, through a cumulative-effect adjustment directly to retained earnings. Upon adoption, we increased deferred tax liabilities by approximately $1.7 million and recognized an offsetting decrease to retained earnings.
In January 2017, the FASB issued accounting guidance which clarifies the definition of a business with the objective of adding guidance to assist in evaluating whether transactions should be accounted for as acquisitions of assets or businesses. The amendment provides criteria for determining when a transaction involves the acquisition of a business. If substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, then the transaction does not involve the acquisition of a business. If the criteria are not met, then the amendment requires that to be considered a business, the operation must include at a minimum an input and a substantive process that together significantly contribute to the ability to create an output. The guidance may reduce the number of transactions accounted for as business acquisitions. This accounting guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and early adoption is permitted. The amendments should be applied prospectively, and no disclosures are required at the effective date. We adopted this accounting guidance effective April 1, 2018. This accounting guidance has had no impact on our financial statements since adoption as we have not entered into any transactions during this period.
In March 2017, the FASB issued accounting guidance related to the presentation of net periodic pension cost and net periodic post-retirement benefit cost. The accounting guidance requires employers to disaggregate the service cost component from the other components of net benefit cost and disclose the amount of net benefit cost that is included in the statement of operations or capitalized in assets, by line item. The accounting guidance requires employers to report the service cost component in the same line item(s) as other compensation costs and to report other pension-related costs (which include interest costs, amortization of pension-related costs from prior periods, and the gains or losses on plan assets) separately and exclude them from the subtotal of operating income. The accounting guidance also allows only the service cost component to be eligible for capitalization when applicable. This accounting guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and early adoption is permitted as of the first interim period of an annual period for which interim or annual financial statements have not been issued. The accounting guidance requires application on a retrospective basis for the presentation of the service cost component and the other components of net periodic pension cost and net periodic post-retirement benefit cost in the statement of operations and on a prospective basis for the capitalization of the service cost component of net periodic pension cost

and net periodic post-retirement benefit in assets. We adopted this accounting guidance effective April 1, 2018, and our statement of operations was retrospectively adjusted by $0.1 million and $0.1 million with an increase in direct cost and a corresponding credit in other income (expense), net for the three and sixnine months ended September 30,December 31, 2017, respectively.
In May 2017, the FASB issued accounting guidance on determining which changes to the terms or conditions of share-based payment awards require an entity to apply modification accounting. This pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2017, with early adoption permitted, and is applied prospectively to changes in terms or conditions of awards occurring on or after the adoption date. We have adopted this accounting guidance effective April 1, 2018, with no impact on our financial statements as there were no changes to the terms or conditions of share-based payment awards.
In February 2018, the FASB issued new accounting guidance on income statement reporting of comprehensive income, specifically pertaining to reclassification of certain tax effects from accumulated other comprehensive income. This pronouncement is effective for fiscal years, and for interim periods within those years, beginning after December 15, 2018, with early adoption permitted, and is applied prospectively to changes in terms or conditions of awards occurring on or after the adoption date. We

have not yet adopted this accounting guidance and are currently evaluating the effect this accounting guidance will have on our financial statements.
In June 2018, the FASB issued an amendment to the accounting guidance related to accounting for employee share-based payments which clarifies that an entity should recognize excess tax benefits in the period in which the amount of the deduction is determined. This amendment is effective for annual periods beginning after December 15, 2018. We have not yet adopted this accounting guidance and are currently evaluating the effect this accounting guidance will have on our financial statements.
In August 2018, the FASB modified the disclosure requirements on fair value measurements. The amendment modifies, removes, and adds several disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement. The amendment is effective for fiscal years ending after December 15, 2021 for public business entities and early adoption is permitted. We have not yet adopted this accounting guidance and are currently evaluating the effect this accounting guidance will have on our disclosure requirements.    
In August 2018, the FASB modified disclosure requirements for employers that sponsor defined benefit pension plans. Certain disclosure requirements were removed and certain disclosure requirements were added. The amendment also clarifies disclosure requirements for projected benefit obligation (“PBO”) and accumulated benefit obligation (“ABO”) in excess of respective plan assets. The amendment is effective for fiscal years ending after December 15, 2020 for public business entities and early adoption is permitted. We have not yet adopted this accounting guidance and are currently evaluating the effect this accounting guidance will have on our disclosure requirements.
In August 2018, the FASB issued new accounting guidance that addresses the accounting for implementation costs associated with a hosted service. The guidance provides that implementation costs be evaluated for capitalization using the same criteria as that used for internal-use software development costs, with amortization expense being recorded in the same income statement expense line as the hosted service costs and over the expected term of the hosting arrangement. This guidance is effective for public business entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years, with early adoption permitted. The guidance will be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. We have not yet adopted this accounting guidance and are currently evaluating the effect this accounting guidance will have on our financial statements.

In October 2018, the FASB amended the guidance for determining whether a decision-making fee is a variable interest. The amendments require organizations to consider indirect interests held through related parties under common control on a proportional basis rather than as the equivalent of a direct interest in its entirety (as currently required in generally accepted accounting principles). Therefore, these amendments likely will result in more decision makers not consolidating variable interest entities (“VIEs”). This amendment is effective beginning in our fiscal year 2021 financial statements. We have not yet adopted this accounting guidance and are currently evaluating the effect this accounting guidance will have on our disclosure requirements.

Note 2 — ACQUISITION AND DISPOSITION
Columbia Helicopters — On February 11, 2019, we announced that our agreement to acquire Columbia Helicopters, Inc. (“Columbia”) had been terminated by mutual agreement of the parties. In connection with the termination, we paid $20 million to Columbia, which will be included as expense in our condensed consolidated statements of operations for the three months ended March 31, 2019. Upon termination of the acquisition agreement, the financing agreements related to the acquisition also terminated pursuant to their respective terms. Due to the termination of the acquisition agreement, the amendment to the indenture for the 8.75% Senior Secured Notes, for which the Company obtained the requisite consent of holders of such notes in connection with the planned acquisition financing, did not become operative, and the related consent fees did not become payable.
Eastern Airways and Humberside Airport — Bristow Helicopters Limited, an indirect consolidated affiliate of the Company (“Bristow Helicopters”), together with its legal and financial advisors, pursued various transactions to exit the Eastern Airways business, which made negative contributions to our Adjusted EBITDA in each of the last three fiscal years, including pursuing a sales process with several third parties over an extended period. On May 10, 2019, Bristow Helicopters completed the sale of all of the shares of Eastern Airways to Orient Industrial Holdings Limited (“OIHL”), an entity affiliated with Mr. Richard Lake, pursuant to a Sale and Purchase Agreement (the “EAIL Purchase Agreement”). Pursuant to the EAIL Purchase Agreement and related agreements, Bristow Helicopters contributed approximately £17.1 million to Eastern Airways as working capital, OIHL acquired Eastern Airways, Bristow Helicopters retained its controlling ownership of the shares in Humberside International Airport Limited that it previously held through Eastern Airways and certain intercompany balances between Bristow Helicopters and Eastern Airways were written off. As a result of the transaction, OIHL now owns and operates Eastern Airways, which had previously operated as a separate unit within Bristow Group, and Bristow Helicopters maintains its controlling interest in Humberside Airport, from which Bristow Helicopters provides U.K. SAR services.
The EAIL Purchase Agreement contained customary representations and warranties. OIHL agreed to certain covenants with respect to non-solicitation of directors, officers or employees of Bristow Helicopters for a period of 12 months. Pursuant to the terms of the EAIL Purchase Agreement, Bristow Helicopters has the right to appoint an observer to the board of directors of Eastern Airways for an initial period of 12 months following the sale. Eastern Airways also agreed to provide certain transition services for a minimum of 12 months from the date of the completion of the transaction.
Note 3 — REVENUE RECOGNITION
Revenue Recognition
In general, we recognize revenue when a service is provided or a good is sold to a customer and there is a contract. At contract inception, we assess the goods and services promised in our contracts with customers and identify all performance obligations for each distinct promise that transfers a good or service (or bundle of goods or services) to the customer. To identify the performance obligations, we consider all goods or services promised in the contract, whether explicitly stated or implied based on customary business practices. Revenue is recognized when control of the identified distinct goods or services have been transferred to the customer, the transaction price is determined and allocated to the performed performance obligations and we have determined that collection has occurred or is probable of occurring.
A majority of our revenue from contracts with customers is currently generated through two types of contracts: helicopter services and fixed wing services. Each contract type has a single distinct performance obligation as described below.
Helicopter services Our customers major integrated, national and independent offshore energy companies charter our helicopters primarily to transport personnel between onshore bases and offshore production platforms, drilling rigs and other installations. To a lesser extent, our customers also charter our helicopters to transport time-sensitive equipment to these offshore locations. The customers for SAR services include both the oil and gas industry and governmental agencies. Revenue from helicopter services is recognized when the performance obligation is satisfied over time based on contractual rates as the related services are performed.
A performance obligation arises under contracts with customers to render services and is the unit of account under the accounting guidance for revenue. Operating revenue from our oil and gas segment is derived mainly from fixed-term contracts with our customers, a substantial portion of which is competitively bid. A small portion of our oil and gas customer revenue is derived from providing services on an "ad-hoc" basis. Our fixed-term contracts typically have original terms of one year to seven years (subject to provisions permitting early termination by our customers). We account for services rendered separately if they are distinct and the service is separately identifiable from other items provided to a customer and if a customer can benefit from the services rendered on its own or with other resources that are readily available to the customer. A contract’s transaction price

17

Table of Contents
BRISTOW GROUP INC. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. Within this contract type for helicopter services, we determined that each contract has a single distinct performance obligation. These services include a fixed monthly rate for a particular model of aircraft, and flight hour services, which represents the variable component of a typical contract with a customer. Rates for these services vary depending on the type of services provided and can be based on a per flight hour, per day, or per month basis. Variable charges within our flight services contracts are not effective until a customer-initiated flight order is received and the actual hours flown are determined; therefore, the associated flight revenue generally cannot be reasonably and reliably estimated beforehand. A contract’s standalone selling prices are determined based upon the prices that we charge for our services rendered. Revenue is recognized as performance obligations are satisfied over time, by measuring progress towards satisfying the contracted services in a manner that best depicts the transfer of services to the customer, which is generally represented by a period of 30 days or less. We typically invoice customers on a monthly basis and the term between invoicing and when the payment is due is typically between 30 and 60 days. In order to offset potential increases in operating costs, our long-term contracts may provide for periodic increases in the contractual rates charged for our services. We recognize the impact of these rates when estimable and applicable, which generally includes written acknowledgment from the customers that they are in agreement with the amount of the rate escalation. Cost reimbursements from customers are recorded as reimbursable revenue with the related reimbursed costs recorded as reimbursable expense on our condensed consolidated statements of operations.
Taxes collected from customers and remitted to governmental authorities and revenue are reported on a net basis in our financial statements. Thus, we exclude taxes imposed on the customer and collected on behalf of governmental agencies to be remitted to these agencies from the transaction price in determining the revenue related to contracts with a customer.
Fixed wing services Eastern Airways and Airnorth provide fixed wing transportation services through regular passenger transport (scheduled airline service with individual ticket sales) and charter services. A performance obligation arises under contracts with customers to render services and is the unit of account under the new accounting guidance for revenue. Within fixed wing services, we determined that each contract has a single distinct performance obligation. Revenue is recognized over time at the earlier of the period in which the service is provided or the period in which the right to travel expires, which is determined by the terms and conditions of the ticket. Ticket sales are recorded within deferred revenue in accordance with the above policy. Both chartered and scheduled airline service revenue is recognized net of passenger taxes and discounts. Eastern Airways was sold on May 10, 2019.

Contract Assets, Liabilities and Receivables
We generally satisfy performance of contract obligations by providing helicopter and fixed wing services to our customers in exchange for consideration. The timing of performance may differ from the timing of the customer’s payment, which results in the recognition of a contract asset or a contract liability. A contract asset exists when we have a contract with a customer for which revenue has been recognized (i.e. services have been performed), but customer payment is contingent on a future event (i.e. satisfaction of additional performance obligations). These contract assets are transferred to receivables when the right to consideration becomes unconditional. Contract liabilities relate to deferred revenue in which advance consideration is received from customers for contracts where revenue is recognized on future performance of services.
As of September 30December 31 and March 31, 2018, receivables related to services performed under contracts with customers were $180.0$160.5 million and $176.5 million, respectively. All receivables from non-affiliates and affiliates are broken out further in our condensed consolidated balance sheets. During the sixnine months ended September 30,December 31, 2018, we recognized $10.1$9.6 million of revenue from outstanding contract liabilities as of March 31, 2018. Contract liabilities related to services performed under contracts with customers was $9.8$7.9 million and $13.3 million as of September 30December 31 and March 31, 2018, respectively. Contract liabilities are primarily generated by our fixed wing services where customers pay for tickets in advance of receiving our services and advanced payments from helicopter services customers. There were no contract assets as of September 30December 31 and March 31, 2018.
For the three and sixnine months ended September 30,December 31, 2018, there was zero$1.9 million and $1.0$1.9 million, respectively, of revenue recognized from satisfied performance obligations related to prior periods (for example, due to changes in transaction price).

Although substantially all of our revenue is under contract, due to the nature of our business we do not have significant remaining performance obligations as our contracts typically include unilateral termination clauses that allow our customers to terminate existing contracts with a notice period of 30 to 180 days. The table above includes performance obligations up to the point where the parties can cancel existing contracts. Any applicable cancellation penalties have been excluded. As such, our actual remaining performance obligation revenue is expected to be greater than what is reflected above. In addition, the remaining performance obligation disclosure does not include expected consideration related to performance obligations of a variable nature (i.e., flight services) as they cannot be reasonably and reliably estimated.
Other Considerations and Practical Expedients
We were awarded a government contract to provide SAR services for all of the U.K., which commenced in April 2015. We previously incurred costs related to this contract that generate or enhance the resources used to fulfill the performance obligation within the contract and the costs are expected to be recoverable. These contract acquisition and pre-operating costs qualify for capitalization. We amortize these capitalized contract acquisition and pre-operating costs related to the UK SAR contract and two customer contracts in Norway. We determined that an amortization method that allocates the capitalized costs on a relative basis to the revenue recognized is a reasonable and systematic basis for the amortization of the pre-operating costs asset. For further details on the short and long-term pre-operating cost balances, see Note 1.
We incur incremental direct costs for obtaining contracts through sales commissions paid to ticket agents to sell seats on regular public transportation flights for our fixed-wing services only. We utilize the practical expedient allowed by the FASB that permits us to expense the incremental costs of obtaining a contract when incurred, if the amortization period of the contract asset that we otherwise would have recognized is one year or less.
In addition, we have applied the tax practical expedient to exclude all taxes in the scope of the election from the transaction price and the invoice practical expedient that allows us to recognize revenue in the amount to which we have the right to invoice the customer and corresponds directly with the value to the customer of our performance completed to date.
Note 34 — VARIABLE INTEREST ENTITIES
A VIE is an entity that either (i) has insufficient equity to permit the entity to finance its activities without additional subordinated financial support or (ii) has equity investors who lack the characteristics of a controlling financial interest. A VIE is consolidated by its primary beneficiary. The primary beneficiary has both the power to direct the activities that most significantly impact the entity’s economic performance and the obligation to absorb losses or the right to receive benefits from the entity that could potentially be significant to the VIE. If we determine that we have operating power and the obligation to absorb losses or receive benefits, we consolidate the VIE as the primary beneficiary, and if not, we do not consolidate.
As of September 30,December 31, 2018, we had interests in four VIEs of which we were the primary beneficiary, which are described below, and had no interests in VIEs of which we were not the primary beneficiary. See Note 2 to the fiscal year 2018 Financial Statements for a description of other investments in significant affiliates.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
(Unaudited)


Bristow Aviation Holdings Limited — We own 49% of Bristow Aviation Holdings Limited’s (“Bristow Aviation”) common stock and a significant amount of its subordinated debt. Bristow Aviation is incorporated in England and, through its subsidiaries, holds all of the outstanding shares in Bristow Helicopters Limited (“Bristow Helicopters”).Helicopters. Bristow Aviation’s subsidiaries provide industrial aviation services to customers primarily in the U.K., Norway, Australia, Nigeria and Trinidad and fixed wing services primarily in the U.K. and Australia. Bristow Aviation is organized with three different classes of ordinary shares having disproportionate voting rights. The Company, Caledonia Investments plc (“Caledonia”) and a European Union investor (the “E.U. Investor”) own 49%, 46% and 5%, respectively, of Bristow Aviation’s total outstanding ordinary shares, although Caledonia has voting control over the E.U. Investor’s shares.
In addition to our ownership of 49% of Bristow Aviation’s outstanding ordinary shares, in May 2004, we acquired eight million shares of deferred stock, essentially a subordinated class of stock with no voting rights, from Bristow Aviation for £1 per share ($14.4 million in total). We also have £91.0 million ($118.7115.9 million) principal amount of subordinated unsecured loan stock (debt) of Bristow Aviation bearing interest at an annual rate of 13.5% and payable semi-annually. Payment of interest on such debt has been deferred since its incurrence in 1996. Deferred interest accrues at an annual rate of 13.5% and aggregated $2.3 billion as of September 30,December 31, 2018.
Our operations in the U.K. are subject to the Civil Aviation Act 1982 and other similar English and E.U. statutes and regulations. We carry persons and property in our aircraft pursuant to an operating license issued by the Civil Aviation Authority (the “CAA”). The Company, Caledonia,holder of an operating license must meet the ownership and control requirements of Council Regulation 2407/92. To operate under this license, the company through which we conduct operations in the U.K., Bristow Helicopters, must be owned directly or through majority ownership by E.U. Investornationals, and Bristow Aviation have entered into a shareholder agreement respecting, among other things, the compositionmust at all times be effectively controlled by them. Our ownership of the board of directors of Bristow Aviation. On matters coming before Bristow Aviation’s board, Caledonia’s representatives have a total of three votes and the two other directors have one vote each. In addition, Caledonia has the right to nominate two persons to our board of directors and to replace any such directors so nominated, provided that Caledonia owned (1) at least 1,000,000 shares of common stock of the Company or (2) at least 49% of the total outstandingordinary shares of Bristow Aviation. AccordingAviation, the entity that owns Bristow Helicopters, is to Caledonia’s most recent Form 13F filedcomply with the SEC on October 10, 2018, Caledonia was no longer the direct beneficial owner of any shares of our common stock as of September 30, 2018. Accordingly, pursuant to the terms of the Master Agreement dated December 12, 1996 among Caledonia and the Company, Caledonia does not currently satisfy the requirements to designate directors for nomination to our board of directors.these restrictions.
Caledonia, the Company and the E.U. Investor also have entered into a put/call agreement under which, upon giving specified prior notice, we have the right to buy all the Bristow Aviation shares held by Caledonia and the E.U. Investor, who, in turn, each have the right to require us to purchase such shares. UnderAs discussed above, under current English law, we would be required, in order for Bristow Aviation to retain its operating license, to find a qualified E.U. investor to own any Bristow Aviation shares we have the right to acquire under the put/call agreement. The only restriction underIn addition, the put/call agreement limitinglimits our ability to exercise the put/call option isthrough a requirement to consult with the Civil Aviation Authority (the “CAA”)CAA in the U.K. regarding the suitability of the new holder of the Bristow Aviation shares. The put/call agreement does not contain any provisions should the CAA not approve the new E.U. investor. However, we would work diligently to find an E.U. investor suitable to the CAA. The amount by which we could purchase the shares of the other investors holding 51% of the equity of Bristow Aviation is fixed under the terms of the call option, and we have reflected this amount on our condensed consolidated balance sheets as noncontrolling interest. On March 14, 2019, the E.U. Investor provided notice of his intent to exercise his right to require us or a qualified E.U. investor to purchase his Bristow Aviation shares for £100,000. In addition, on April 29, 2019, Caledonia provided notice of its intent to exercise its right to require us or a qualified E.U. investor to purchase its Bristow Aviation shares for £920,000. With respect to each of the notices from the E.U. Investor and Caledonia, we have 180 days from receipt of such notice to (i) nominate either Bristow Group Inc., a related party of Bristow Group Inc. or an E.U. investor as the purchaser of the relevant shares and (ii) confirm that we have been notified by the CAA that the holding of any of our licenses granted by the CAA will not be affected as a result of such transfer. We are in the process of identifying a qualified E.U. investor to be the new holder of such Bristow Aviation shares.
Furthermore, the call option provides a mechanism whereby the economic risk for the other investors is limited should the financial condition of Bristow Aviation deteriorate. The call option price is the nominal value of the ordinary shares held by the noncontrolling shareholders (£1.0 million as of September 30,December 31, 2018) plus an annual guaranteed rate of return less any prepayments of such call option price and any dividends paid on the shares concerned. We can elect to pre-pay the guaranteed return element of the call option price wholly or in part without exercising the call option. No dividends have been paid by Bristow Aviation. We have accrued the annual return due to the other shareholders at a rate of sterling LIBOR plus 3% or 6% (prior to May 2004, the rate was fixed at 12%) by recognizing noncontrolling interest expense on our condensed consolidated statements of operations, with a corresponding increase in noncontrolling interest on our condensed consolidated balance sheets. Prepayments of the guaranteed return element of the call option are reflected as a reduction in noncontrolling interest on our condensed consolidated balance sheets. The other investors have an option to put their shares in Bristow Aviation to us. The put option price is calculated in the same way as the call option price except that the guaranteed rate for the period to April 2004 was 10% per annum. If the put option is exercised, any pre-payments of the call option price are set off against the put option price.

Bristow Helicopters (Nigeria) Ltd. — Bristow Helicopters (Nigeria) Ltd. (“BHNL”) is a joint venture in Nigeria in which Bristow Helicopters owns a 48% interest, a Nigerian company owned 100% by Nigerian employees owns a 50% interest and an employee trust fund owns the remaining 2% interest as of September 30,December 31, 2018. BHNL provides industrial aviation services to customers in Nigeria.
In order to be able to bid competitively for our services in the Nigerian market, we were required to identify local citizens to participate in the ownership of entities domiciled in the region. However, these owners do not have extensive knowledge of the aviation industry and have historically deferred to our expertise in the overall management and day-to-day operation of BHNL (including the establishment of operating and capital budgets and strategic decisions regarding the potential expansion of BHNL’s operations). We have also historically provided subordinated financial support to BHNL and will need to continue to do so unless and until BHNL acquires sufficient equity to permit itself to finance its activities without that additional support from us. As we have the power to direct the most significant activities affecting the economic performance and ongoing success of BHNL and hold a variable interest in the entity in the form of our equity investment and working capital infusions, we consolidate BHNL as the primary beneficiary. The employee-owned Nigerian entity referenced above purchased a 19% interest in BHNL in December 2013 with proceeds from a loan received from BGI Aviation Technical Services Nigeria Limited (“BATS”). In July 2014, the employee-owned Nigerian entity purchased an additional 29% interest with proceeds from a loan received from Bristow Helicopters (International) Limited (“BHIL”). In April 2015, Bristow Helicopters purchased an additional 8% interest in BHNL and the employee-owned Nigerian entity purchased an additional 2% interest with proceeds from a loan received from BHIL. Both BATS

and BHIL are wholly-owned subsidiaries of Bristow Aviation. The employee-owned Nigerian entity is also a VIE that we consolidate as the primary beneficiary and we eliminate the loans discussed above in consolidation.
BHNL is an indirect subsidiary of Bristow Aviation; therefore, financial information for this entity is included within the amounts for Bristow Aviation and its subsidiaries presented above.
Pan African Airlines (Nigeria) Ltd. — Pan African Airlines (Nigeria) Ltd. (“PAAN”) is a joint venture in Nigeria with local partners in which we own aan interest of 50.17% interest.. PAAN provides industrial aviation services to customers in Nigeria.
The activities that most significantly impact PAAN’s economic performance relate to the day-to-day operation of PAAN, setting the operating and capital budgets and strategic decisions regarding the potential expansion of PAAN’s operations. Throughout the history of PAAN, our representation on the board and our secondment to PAAN of its managing director has enabled us to direct the key operational decisions of PAAN (without objection from the other board members). We have also historically provided subordinated financial support to PAAN. As we have the power to direct the most significant activities affecting the economic performance and ongoing success of PAAN and hold a variable interest in the form of our equity investment and working capital infusions, we consolidate PAAN as the primary beneficiary. However, as long as we own a majority interest in PAAN, the separate presentation of financial information in a tabular format for PAAN is not required.

Short-termConsent Solicitation and Supplemental Indenture — On November 21, 2018, we completed the previously announced solicitation of consents from holders of our outstanding 8.75% Senior Secured Notes to amend certain provisions of the indenture governing the 8.75% Senior Secured Notes pursuant to a supplemental indenture (the “Supplemental Indenture”). The Supplemental Indenture became effective upon the execution and delivery thereof, but would become operative only upon the delivery of a cash payment to eligible holders of the 8.75% Senior Secured Notes who validly delivered and did not revoke consents prior to the receipt of the consents required to effect the amendments under the Supplemental Indenture. As the cash payment was not made, the Supplemental Indenture did not become operative.
ABL Facility — On April 17, 2018, two of our subsidiaries entered into a new asset-backed revolving credit facility (the “ABL Facility”), which provides for commitments in an aggregate amount of $75 million, with a portion allocated to each borrower subsidiary, subject to an availability block of $15 million and a borrowing base calculated by reference to eligible accounts receivable. The maximum amount of the ABL Facility may be increased from time to time to a total of as much as $100 million, subject to the satisfaction of certain conditions, and any such increase would be allocated among the borrower subsidiaries. The ABL Facility matures in April 2023, subject to certain early maturity triggers related to maturity of other material debt or a change of control of the Company. Amounts borrowed under the ABL Facility are secured by certain accounts receivable owing to the borrower subsidiaries and the deposit accounts into which payments on such accounts receivable are deposited. As of December 31, 2018, there were no outstanding borrowings reclassificationunder the ABL Facility nor had we made any draws during the nine months ended December 31, 2018. As of December 31, 2018, we had $16.2 million in letters of credit outstanding under the ABL Facility and our available borrowing capacity under the ABL Facility was $5.6 million.

We amended the ABL Facility pursuant to a letter agreement, dated effective as of November 7, 2018 and made by us and agreed to by Barclays Bank PLC, on behalf of the finance parties under the ABL Facility (the “First ABL Amendment”).  The First ABL Amendment amends the ABL Facility to, among other things, provide that certain of the provisions, including covenants and events of default contained therein, will exclude unrestricted subsidiaries (as designated under the indenture governing the 8.75% Senior Secured Notes) from the requirements and defaults thereunder.
We also amended the ABL Facility pursuant to a letter agreement effective as of February 19, 2019 and made by us and agreed to by Barclays Bank PLC, on behalf of the finance parties under the ABL Facility (the “Second ABL Amendment”). Under the Second ABL Amendment, the Company received a waiver of any Default (as defined in the ABL Facility) that would otherwise exist or occur under the ABL Facility as a result of (i) our failure to provide our unaudited consolidated financial statements for the quarter ended December 31, 2018 within 45 days after the end of the quarter or (ii) certain representations and warranties not being correct when made due to the existence of any Default specified in the preceding clause (i); provided that we must provide such unaudited consolidated financial statements within 75 days after the end of the quarter. In addition, the Second ABL Amendment amends (i) the borrowing base determination provisions in the ABL Facility and (ii) the maturity date of the ABL Facility, which was previously five years from the date of the ABL Facility, to December 14, 2021 (in each case, subject to certain early maturity triggers related to maturity of other material debt or a change of control of us). The ABL Facility was further amended pursuant to the ABL Waiver (as defined herein). As discussed below under “—Waiver of Defaults,” the ABL Waiver provided that the maturity date of December 14, 2021 shall be subject to certain early maturity triggers related to a Change of Control of the Company (as such definition has been amended by the ABL Waiver) or the ABL Waiver Termination Date (as defined herein).

Eastern Airways Debt All outstanding obligations under Eastern Airways’ revolving credit facility matured on December 31, 2018, and a final repayment of $7.4 million was made in December 2018. Eastern Airways’ debt also included borrowings under a term loan facility that matured on August 31, 2018, and was repaid in a principal amount of $4.9 million in August 2018.
Debt CovenantsCertain of our credit facilities which are secured by pledges of aircraft, with aggregate outstanding borrowings of $391.2 million at December 31, 2018, and certain of our aircraft leasing arrangements to which we are the lessee, contain covenants of a non-financial nature related to pledged and leased aircraft. Each aircraft pledge specifically identifies the airframes and engines of the aircraft pledged to its credit facility. Similarly, each aircraft lease specifically identifies the airframe(s) and engines of the aircraft covered by the lease. The agreements contain a requirement to maintain specific engines on each specified airframe with limited exceptions for, among other things, the repair and maintenance of the engines.  From time to time, engines are removed and replaced on an airframe. In some cases, these actions are permitted under the credit and lease agreements so long

as (a) a pledged or leased engine is replaced with another engine subject to the same transaction  or, in some cases, any other engine, so long as such other engine is free and clear of liens other than certain permitted liens, and/or (b) in the case of a “loaner” engine furnished by a maintenance provider temporarily replacing a pledged or leased engine, the “loaner” engine is replaced with an engine (which may be the original engine, post-maintenance) subject to the same transaction within 180 days after the removal of the original engine. During the three months ended December 31, 2018, we determined that in some instances a “loaner” engine owned by a maintenance provider and installed on a pledged or leased airframe had been on that airframe for more than 180 days after the removal of the original engine. We are reliant upon third-party maintenance providers to complete maintenance work on these subject engines; however, in some instances these maintenance providers did not complete the required maintenance work on an engine within the 180-day period permitted by the relevant agreement for the engine can be separated from the assigned airframe, and the relevant maintenance providers have been able to provide a timetable for the ultimate completion of the work on those engines. These instances, while involving a small subset of the approximately 385 helicopter engines that were then subject to our secured financings or helicopter leases, constituted defaults under the affected credit and lease agreements. All issues related to this matter were cured by December 31, 2018 for all but nine helicopter engines (relating to three agreements) where a pledged or leased engine was not returned to the pledged or leased airframe within the specified period due to delays by the relevant maintenance service provider. We obtained waivers of such non-compliance under the applicable agreements, extending the time for the return of each pledged or leased engine to the relevant pledged or leased airframe to the earlier of (i) the date that occurs 30 days after the receipt by the Company of such engine at our facility where the relevant airframe is then located or (ii) February 10, 2020.
Classification of Debt The Company’s liquidity outlook has recently changed resulting in substantial doubt about the Company’s ability to continue as a going concern. As discussed in Note 1, on the Explanatory Note included elsewhere in this Quarterly Report, on May 11, 2019,Petition Date, the Debtors filed the Chapter 11 Cases in the Bankruptcy Court seeking relief under Chapter 11 of the Bankruptcy Code. The Debtors’ Chapter 11 Cases are jointly administered under the caption In re: Bristow Group Inc., et al., Main Case No. 19-32713. The Debtors continue to operate their businesses and manage their properties as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court. EachIn addition, each of the commencement of the Chapter 11 Cases and the delivery of the AmendedCompany’s Annual Report on Form 10-K for the fiscal year ended March 31, 2018, as amended by the amendment thereto, with a going concern qualification or explanation included in the accompanying report of the Company’s independent registered public accounting firm constituted an event of default under certain of our secured equipment financings, giving those secured equipment lenders the right to accelerate repayment of the applicable debt, subject to Chapter 11 protections, and triggering cross-default and/or cross-acceleration provisions in substantially all of our other debt instruments should that right to accelerate repayment be exercised. As such, substantially all of our debt is in default and accelerated, but subject to stay under the Bankruptcy Code. As a result of the facts and circumstances discussed above, the Company concluded that substantially all debt balances of approximately $1.4 billion as of MarchDecember 31, 2018 should be reclassified fromclassified as short-term borrowings and current maturities of long-term to short-term within the Amended 10-K and as of September 30, 2018 within this Amendment No. 1debt on our condensed consolidated balance sheet.
ABL Facility Notice of Default of Aircraft Leases On March 22, 2019, we received a notice of default with respect to four aircraft leases (the “Leases”) entered into in September 2014 by our subsidiary BriLog Leasing Ltd., as lessee. The notice of default cited failure by the lessee to comply with its obligations to maintain the aircraft leased pursuant to such Leases so as to enable the certificate of airworthiness for the aircraft to be continually maintained without restriction or limitation. Unless the lessee remedied such default within 30 days after the date of such notice, such default would mature into an Event of Default (as defined in the Leases). Prior to the end of such 30-day period, we reached a settlement with respect to such default, and therefore, such default did not mature into an Event of Default.
Waiver of DefaultsOn April 17, 2018, twoPrior to the Petition Date, we entered into waiver letters with respect to certain of our subsidiariesdebt agreements, including the credit agreement, dated as of July 17, 2017, among Bristow Equipment Leasing Ltd., the several banks, other financial institutions and other lenders from time to time party thereto and PK AirFinance S.à r.l., as agent and as security trustee (as amended, the “PK Credit Agreement”); the term loan credit agreement, dated as of February 1, 2017, among Bristow U.S. LLC, the several banks, other financial institutions and other lenders from time to time party thereto and Macquarie Bank Limited, as administrative agent and as security agent (as amended, the “Macquarie Credit Agreement”); the ABL Facility; and certain other secured equipment financings and leases. Pursuant to such waiver letters, we received waivers of breaches, defaults or events of default under such debt agreements arising from the Company’s failure to timely provide its unaudited consolidated financial statements for the quarter ended December 31, 2018 and/or the failure to make the April 15, 2019 interest payment due on the 6¼% Senior Notes due 2022 (the “6¼% Senior Notes”) by May 15, 2019, and certain other related events of default and cross-defaults. As discussed below under “—Events of Default,” the filing of the Chapter 11 Cases constituted an event of default that accelerated the obligations under the PK Credit Agreement and the Macquarie Credit Agreement.

On May 10, 2019, Bristow Norway AS and Bristow Helicopters, as borrowers and guarantors, and the Company, as guarantor, entered into a new asset-backed revolvingwaiver letter (the “ABL Waiver”) with Barclays Bank PLC, as agent, and Credit Suisse AG, Cayman Islands Branch, as lender, with respect to the ABL Facility. The ABL Waiver waives, subject to certain conditions, any Default (as defined in the ABL Facility) or cross-defaults that would otherwise exist or occur under the ABL Facility as a result of, among other things, (i) the Company’s failure to timely provide its unaudited consolidated financial statements for the quarters ended December 31, 2018 and March 31, 2019, (ii) the amendment of the Company’s periodic reports for fiscal year 2018 as previously disclosed, (iii) the failure to make the April 15, 2019 interest payment due on the 6¼% Senior Notes, (iv) potential cross defaults under the 4½% Convertible Senior Notes and 8.75% Senior Secured Notes, (v) other events related to the Chapter 11 Cases, potential insolvency issues or possible failure to comply with certain financial covenants or (vi) certain representations and warranties not being correct when made. Such Defaults are waived until the date (the “ABL Waiver Termination Date”) on which the Company or its subsidiaries enter into or modify debt agreements that would materially adversely impact the ability to perform obligations under the ABL Facility, any security that is not permitted security is granted over the share capital or assets of either borrower or the Chapter 11 Cases are dismissed or converted to a case under Chapter 7 of the Bankruptcy Code, subject to certain conditions as specified in the ABL Waiver. The ABL Waiver contains certain amendments to the ABL Facility, including (i) expanding the definition of Change of Control to include the consummation of a plan of reorganization in connection with the commencement of a bankruptcy proceeding and (ii) providing that the maturity date of December 14, 2021 shall be subject to certain early maturity triggers related to a Change of Control of the Company (as such definition has been amended by the ABL Waiver) or the ABL Waiver Termination Date.
On May 10, 2019, Bristow Aircraft Leasing Limited (“BALL”), as borrower, entered into a waiver letter (the “Lombard Waiver”) with Lombard North Central Plc, as administrative agent and as security trustee, with respect to the term loan credit agreement, dated as of November 11, 2016 (the “BALL Lombard Credit Agreement”). If an Insolvency Proceeding (as defined in the Lombard Waiver) is commenced on or before May 15, 2019, the Lombard Waiver extends, subject to certain conditions, the waivers received under the previous waiver letter (as described in our Current Report on Form 8-K filed with the SEC on April 15, 2019), until the earliest of (a) certain events related to a plan of reorganization or liquidation of the Company, Insolvency Proceeding or debtor-in-possession financing or (b) December 15, 2019 (the “Lombard Waiver Termination Date”). In addition, the Lombard Waiver waives, until the Lombard Waiver Termination Date, any Default or Event of Default (each as defined in the BALL Lombard Credit Agreement) as a result of (i) the amendment of the Company’s periodic reports for fiscal year 2018, (ii) the possible commencement of an Insolvency Proceeding or any related acceleration of other material indebtedness and (iii) the possible occurrence of an Event of Default under the term loan credit agreement, dated as of November 11, 2016, among Bristow U.S. Leasing LLC, as borrower, the lenders from time to time party thereto and Lombard North Central plc, as administrative agent and as security trustee (the “BULL Lombard Credit Agreement”), subject to certain conditions.
Events of DefaultThe filing of the Chapter 11 Cases constituted an event of default that accelerated the obligations under the following instruments and agreements:
the Third Supplemental Indenture, dated as of October 12, 2012, to the Indenture, dated as of June 17, 2008 (the “Base Indenture”), among the Company, the guarantors named therein and Wilmington Trust, National Association (“Wilmington Trust”), as successor trustee to U.S. Bank National Association (“U.S. Bank”), and our 6¼% Senior Notes issued thereunder;
the Sixth Supplemental Indenture to the Base Indenture, dated as of December 18, 2017, among the Company, the guarantors named therein and Wilmington Trust, as successor trustee to U.S. Bank, and our 4½% Convertible Senior Notes issued thereunder;
the Indenture, dated as of March 6, 2018, among the Company, the guarantors named therein and U.S. Bank, as trustee and collateral agent, and our 8.75% Senior Secured Notes issued thereunder;
the PK Credit Agreement;
the Macquarie Credit Agreement;
the BULL Lombard Credit Agreement; and
various aircraft operating leases and real estate leases.
The instruments and agreements described above provide that, as a result of the commencement of the Chapter 11 Cases, the financial obligations thereunder, including for the debt instruments any principal amount, together with accrued interest thereon, are immediately due and payable. However, any efforts to enforce payment of such financial obligations under such instruments

and agreements are automatically stayed as a result of the filing of the Chapter 11 Cases and the holders’ rights of enforcement in respect of such financial obligations are subject to the applicable provisions of the Bankruptcy Code.
Term Loan AgreementOn May 10, 2019, the Company entered into a Term Loan Credit Agreement, dated the same date (the “Term Loan Agreement”), by and among the Company and Bristow Holdings Company Ltd. III (“BHC III”), as borrowers, certain subsidiaries of the Company as guarantors party thereto, the lenders from time to time party thereto (initially, certain holders of the 8.75% Senior Secured Notes), and Ankura Trust Company, LLC, as administrative agent, for a senior secured term loan of $75 million (the “2019 Term Loan”). Immediately upon entering into the Term Loan Agreement, and prior to the Petition Date, the Company and BHC III borrowed the full amount thereunder, the net proceeds of which may be used only in compliance with a cash flow forecast required pursuant to the terms of the Term Loan Agreement, which the Company expects will be used for general corporate purposes, including to fund the working capital and liquidity requirements of the Company during the pendency of the Chapter 11 Cases. The full principal amount of the 2019 Term Loan is due May 10, 2022. At the Company’s election, borrowings under the 2019 Term Loan will bear interest at either (x) the Eurodollar Rate (as defined in the Term Loan Agreement) plus 7% or (y) the Base Rate (as defined in the Term Loan Agreement) plus 6%. The initial borrowings under the 2019 Term Loan will be Eurodollar Rate loans with monthly interest payments. The 2019 Term Loan is secured by a first lien on certain specified collateral, including, among other things, equity pledges of 35% of the equity interests in certain of the Company’s first-tier foreign subsidiaries (the remaining 65% of such entities have been previously pledged under the 8.75% Senior Secured Notes), 100% of the equity of BHC III and Bristow International Panama S. de RL, and two newly formed special-purpose vehicles, as well as a junior lien on certain collateral securing the 8.75% Senior Secured Notes. The borrowers have the option in connection with the consummation of a Reorganization Plan (as defined in the Term Loan Agreement) that is satisfactory to the lenders to require that the 2019 Term Loan be converted into equity of the Company upon consummation of such Reorganization Plan, subject to certain conditions. The Term Loan Agreement contains customary pre-payment requirements.
The Term Loan Agreement contains certain customary negative covenants that, among other things, restrict, subject to certain exceptions, the Company’s and its subsidiaries’ incurrence of additional indebtedness or liens, mergers, dispositions of assets, investments, restricted payments, modifications to material agreements, transactions with affiliates and fundamental changes. In addition, the Term Loan Agreement requires that, on the delivery of each Variance Report (as defined in the Term Loan Agreement), total operating disbursements and total receipts of the Company and its subsidiaries for certain specified periods shall not exceed (with respect to disbursements) or be less than (with respect to total receipts) the aggregate amount forecasted therefor for such period by more (with respect to disbursements) or less (with respect to total receipts) than a specified percentage of the forecasted amount. The Term Loan Agreement also contains customary affirmative covenants and customary representations and warranties.
The Term Loan Agreement specifies certain customary events of default, including, among others, failure to pay principal or interest on the 2019 Term Loan when due, the breach of representations or warranties in any material respect, non-performance of other covenants and obligations, judgments, the occurrence of certain ERISA events and certain change of control events. The filing of the Chapter 11 Cases neither constitutes an event of default nor accelerates the maturity of the Company’s indebtedness under the Term Loan Agreement.
Debtor-in-Possession Commitment LetterIn connection with the Chapter 11 Cases and pursuant to a Commitment Letter, dated May 10, 2019, from the lenders party thereto and agreed to by the Company and BHC III (together, the “DIP Borrowers”), an ad hoc group of holders of the 8.75% Senior Secured Notes has agreed to provide the DIP Borrowers with a superpriority senior secured debtor-in-possession credit facility (the “ABL“DIP Facility”), which on the terms set forth in the DIP Facility Term Sheet attached thereto (the “DIP Term Sheet”). The DIP Term Sheet provides for commitmentsthat, among other things, the DIP Facility shall be comprised of loans in an aggregate principal amount of $75 million, with a portion allocated to each borrower subsidiary,$75.0 million. The availability of the DIP Facility is subject to an availability block of $15 millioncertain conditions and a borrowing base calculatedmilestones, including approval by reference to eligible accountsthe Bankruptcy Court, which has not been obtained at this time.

receivable. The maximum amount of the ABL Facility may be increased from time to time to a total of as much as $100 million, subject to the satisfaction of certain conditions, and any such increase would be allocated among the borrower subsidiaries. The ABL Facility matures in five years, subject to certain early maturity triggers related to maturity of other material debt or a change of control of the Company. Amounts borrowed under the ABL Facility are secured by certain accounts receivable owing to the borrower subsidiaries and the deposit accounts into which payments on such accounts receivable are deposited. As of September 30, 2018, there were no outstanding borrowings under the ABL Facility nor had we made any draws during the six months ended September 30, 2018.

Note 56 — FAIR VALUE DISCLOSURES
Assets and liabilities subject to fair value measurement are categorized into one of three different levels depending on the observability of the inputs employed in the measurement, as follows:
Level 1 – observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.
Level 2 – inputs that reflect quoted prices for identical assets or liabilities in markets which are not active; quoted prices for similar assets or liabilities in active markets; inputs other than quoted prices that are observable for the asset or liability; or inputs that are derived principally from or corroborated by observable market data by correlation or other means.
Level 3 – unobservable inputs reflecting the Company’s own assumptions incorporated in valuation techniques used to determine fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available.

Non-recurring Fair Value Measurements
The majority of our non-financial assets, which include inventories, property and equipment, assets held for sale, goodwill and other intangible assets, are not required to be carried at fair value on a recurring basis. However, if certain triggering events occur such that a non-financial asset is required to be evaluated for impairment and deemed to be impaired, the impaired non-financial asset is recorded at its fair value.

The fair value of inventories using Level 2 and 3 inputs is determined by evaluating the current economic conditions for sale and disposal of spare parts, which includes estimates as to the recoverability of the carrying value of the parts based on historical experience with sales and disposal of similar spare parts, the expected time frame of sales or disposals, the location of the spare parts to be sold and the condition of the spare parts to be sold or otherwise disposed of.
The fair value of aircraft and equipment, using Level 3 inputs, is determined using a market approach. The market approach consisted of a thorough review of recent market activity, available transaction data involving the subject aircraft, current demand and availability on the market. We took into account the age, specifications, accrued hours and cycles, and the maintenance status of each subject aircraft.
The fair value of other intangible assets, using Level 3 inputs, is estimated using the income approach. The estimate of fair value includes unobservable inputs, including assumptions related to future performance, such as projected demand for services, rates, and levels of expenditures.
The fair value of assets held for sale using Level 23 inputs is determined through evaluation of expected sales proceeds for aircraft. This analysis includes estimates based on historical experience with sales, recent transactions involving similar assets, quoted market prices for similar assets and condition and location of aircraft to be sold or otherwise disposed of. The loss for the three and sixnine months ended September 30,December 31, 2018 related to two aircraft held for sale. The loss for the three and nine months ended December 31, 2017 related to twoone and fourfive aircraft held for sale, respectively. Additionally, the loss for the three and sixnine months ended September 30,December 31, 2017 includes a $6.5 million impairment relating to the Bristow Academy disposal group. For further details on Bristow Academy disposal group, see Note 1 to our fiscal year 2018 Financial Statements.

Note 67 — DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES
From time to time, we enter into forward exchange contracts as a hedge against foreign currency asset and liability commitments and anticipated transaction exposures, including intercompany purchases. All derivatives are recognized as assets or liabilities and measured at fair value. We do not use financial instruments for trading or speculative purposes.
During fiscal year 2018 and the sixnine months ended September 30,December 31, 2018, we entered into foreign currency put option contracts of £5 million per month through SeptemberNovember 2019 to mitigate a portion of our foreign currency exposure. These derivatives were designated as cash flow hedges.
The designation of a derivative instrument as a hedge and its ability to meet relevant hedge accounting criteria determines how the change in fair value of the derivative instrument will be reflected in the consolidated financial statements. A derivative qualifies for hedge accounting if, at inception, the derivative is expected to be highly effective in offsetting the hedged item’s underlying cash flows or fair value and the documentation requirements of the accounting standard for derivative instruments and hedging activities are fulfilled at the time we enter into the derivative contract. A hedge is designated as a cash flow hedge, fair value hedge, or a net investment in foreign operations hedge based on the exposure being hedged. The asset or liability value of the derivative will change in tandem with its fair value. For derivatives designated as cash flow hedges, the changes in fair value are recorded in accumulated other comprehensive income (loss). The derivative’s gain or loss is released from accumulated other comprehensive income (loss) to match the timing of the effect on earnings of the hedged item’s underlying cash flows.
We review the effectiveness of our hedging instruments on a quarterly basis. We discontinue hedge accounting for any hedge that we no longer consider to be highly effective. Changes in fair value for derivatives not designated as hedges or those not qualifying for hedge accounting are recognized in current period earnings.
None of our derivative instruments contain credit-risk-related contingent features. Counterparties to our derivative contracts are high credit quality financial institutions.

Aircraft Purchase Contracts — As shown in the table below, we expect to make additional capital expenditures over the next seven fiscal years to purchase additional aircraft. As of September 30,December 31, 2018, we had 2726 aircraft on order and options to acquire an additional four aircraft. Although a similar number of our existing aircraft may be sold during the same period, the additional aircraft on order will provide incremental fleet capacity in terms of revenue and operating income.

In December 2018, a large aircraft order was terminated and we removed $17.5 million of future commitments from the table above. We recorded contract termination costs of $14.0 million included in loss on disposal of assets on our condensed consolidated statements of operations for amounts previously included in construction in progress on our condensed consolidated balance sheets. We have an ongoing dispute with the OEM to recover a portion of these progress payments. For further details, see Note 1.
On May 1, 2019, we entered into an amendment to our agreement with Airbus Helicopters for the purchase of 22 H175 helicopters which includes five aircraft that can be cancelled by us prior to the delivery dates. Pursuant to the amendment, the parties mutually agreed to postpone the delivery dates for such helicopters for 18 months from the previous schedule with the first three helicopters now scheduled for delivery in the second half of fiscal year 2022. The postponement in deliveries resulted in various amendments to the payment terms under the purchase agreement including the deferral of approximately $110.0 million in capital expenditures scheduled for fiscal years 2019 to 2023 into fiscal years 2024 and beyond. Our capital commitments related to these H175 helicopters now total approximately $14.0 million for fiscal years 2020 and 2021. In connection with this amendment, the overall purchase price of these helicopters has been increased by $18.4 million to account for inflation. The impact of this amendment is not included in the table above.
Operating Leases — We have non-cancelable operating leases in connection with the lease of certain equipment, including leases for aircraft, and land and facilities. Rent expense incurred under all operating leases was $49.6$48.2 million and $57.2$42.6 million for the three months ended September 30,December 31, 2018 and 2017, respectively, and $99.7$147.8 million and $115.9$158.5 million for the sixnine months ended September 30,December 31, 2018 and 2017, respectively. Rent expense incurred under operating leases for aircraft was $43.0$42.8 million and $49.7$36.5 million for the three months ended September 30,December 31, 2018 and 2017, respectively, and $87.1$129.9 million and $101.4$137.9 million for the sixnine months ended September 30,December 31, 2018 and 2017, respectively.
The aircraft leases range from base terms of up to 180 months with renewal options of up to 240 months in some cases, include purchase options upon expiration and some include early purchase options. The leases contain terms customary in transactions of this type, including provisions that allow the lessor to repossess the aircraft and require us to pay a stipulated amount if we default on our obligations under the agreements. The following is a summary of the terms related to aircraft leased under operating leases with original or remaining terms in excess of one year as of September 30,December 31, 2018:

Although we have not yet obtained a formal release of liability from the EPA with respect to any of the sites, we believe that our potential liability in connection with the sites is not likely to have a material adverse effect on our business, financial condition or results of operations.
CEO Transition — On November 9, 2018, the Company announced the upcoming retirement of Jonathan E. Baliff, who served as President and Chief Executive Officer of the Company. Mr. Baliff stepped down from the position of President effective November 9, 2018, while continuing to serve as Chief Executive Officer. On February 11, 2019, the Company entered into a Retirement and Consulting Agreement (the “Retirement and Consulting Agreement”) with Mr. Baliff. Under the Retirement and Consulting Agreement, Mr. Baliff ceased to serve as Chief Executive Officer of the Company and resigned from the Board of Directors of the Company (the “Board”), effective February 28, 2019. Commencing March 1, 2019, Mr. Baliff provided consulting services to the Company through June 30, 2019 and received a monthly consulting fee of $30,000.
Mr. Baliff’s retirement constituted a separation of employment entitling him to benefits under the Company’s Management Severance Benefits Plan for U.S. Employees (the “Severance Plan”). Pursuant to the Severance Plan and subject to Mr. Baliff’s execution and non-revocation of a release of claims against the Company, upon his termination of employment, Mr. Baliff became entitled to: (a) severance of $1,442,000, equal to two times Mr. Baliff’s base salary; (b) Company payment of Mr. Baliff’s COBRA premiums for 36 months (extended from 18 months); (c) outplacement services for 12 months; (d) accelerated vesting of Company equity awards and Company performance cash awards granted in June 2016 that would have vested by their terms in June 2019; and (e) a pro-rata bonus, assuming target performance, for the portion of fiscal year 2019 during which Mr. Baliff served as Chief Executive Officer.
In consideration of Mr. Baliff’s agreement to extend the post-termination non-compete and employee non-solicitation provisions from one year to two years, the Company agreed that the following Company equity awards would remain outstanding and continue to vest, subject to Mr. Baliff’s compliance with the restrictive covenants and satisfaction of his obligations under the consulting arrangement described above: (a) options to purchase 43,503 shares of Company stock, scheduled to vest on June 5, 2019; (b) options to purchase 102,190 shares of Company stock, scheduled to vest on June 12, 2019; (c) 74,502 Company restricted stock units, scheduled to vest on June 12, 2020; and (d) 23,927 Company restricted stock units, scheduled to vest on June 5, 2021.
Effective upon Mr. Baliff’s retirement and until the appointment of a new Chief Executive Officer, the Board named Thomas N. Amonett, the Vice-Chairman of the Board and interim President of the Company, to the additional role of interim Chief Executive Officer.
On March 1, 2019, the Company announced that L. Don Miller, Senior Vice President and Chief Financial Officer of the Company, had been appointed to succeed Mr. Baliff as President and Chief Executive Officer of the Company, effective as of the close of business on February 28, 2019. Mr. Miller joined the Board concurrently with the effectiveness of his appointment as President and Chief Executive Officer. Mr. Amonett, who has been serving as the interim President of the Company, was appointed to the role of Executive Vice Chairman of the Board, effective upon the effectiveness of Mr. Miller’s appointment. Brian J. Allman, Vice President and Chief Accounting Officer of the Company, was appointed to succeed Mr. Miller as Senior Vice President and Chief Financial Officer.
Other Purchase Obligations — As of September 30,December 31, 2018, we had $37.7$52.0 million of other purchase obligations representing unfilled purchase orders for aircraft parts and non-cancelable power-by-the-hour maintenance commitments.
Sikorsky Lawsuit — On January 8, 2019, we filed suit in the District Court of Harris County, Texas against Sikorsky Aircraft Corporation (“Sikorsky”) for breach of contract, unjust enrichment and conversion as a result of Sikorsky terminating a sales agreement after we sought to delay delivery of a helicopter and retaining our $11.7 million deposit as liquidated damages. We are seeking a ruling that Sikorsky be required to return the deposit and provide an accurate calculation of its damages under the sales agreement. Sikorsky has challenged venue, and discovery related thereto is underway. With the advice of counsel, we are evaluating the feasibility of transferring the matter to the Bankruptcy Court for disposition.
Other Matters — Although infrequent, aircraft accidents have occurred in the past, and the related losses and liability claims have been covered by insurance subject to deductible, self-insured retention and loss sensitive factors.
On March 10, 2019, one of our Bell 407 model aircraft was involved in an accident in the Gulf of Mexico in which one pilot and one passenger were fatally injured. The cause(s) of the accident remain unknown at this time. We continue to work with authorities in their investigation.
As previously reported, on April 29, 2016, another company’s EC 225LP (also known as a H225LP) model helicopter crashed near Turøy outside of Bergen, Norway resulting in the European Aviation Safety Agency (“EASA”) issuing airworthiness directives prohibiting

flight of H225LP and AS332L2 model aircraft. On July 20, 2017, the U.K. CAA and NCAA issued safety and operational directives which detail the conditions to apply for safe return to service of H225LP and AS332L2 model aircraft, where operators wish to do so. On July 5, 2018, the Accident Investigation Board Norway issued its final investigation report on the accident. The report cited a fatigue fracture within the epicyclic module of the main gear box as the cause of the accident, and issued safety recommendations in a number of areas, including gearbox design and certification requirements, failure tolerance, and continued airworthiness of the AS332L2 and the H225LP helicopters. We continue not to operate for commercial purposes our 21 H225LP model aircraft, and we are carefully evaluating next steps for the H225LP model aircraft in our operations worldwide, with the safety of passengers and crews remaining our highest priority. Recent third-party market transactions and the development of alternative opportunities outside of our traditional oil and gas services for our H225 aircraft indicateindicated a substantial return to oil and gas service within our operations iswas not likely. See Note 1 for further details.
The Huntington National Bank (“Huntington”) filed suit against the Company and Bristow U.S. LLC in the U.S. District Court for the Southern District of New York (the “Southern District of New York Court”). Huntington alleges violation of an addendum of a lease agreement for failure to arrange for the enrollment of the aircraft engines in a maintenance agreement and seeks approximately $2.5 million in damages. We submitted a counterclaim for approximately $100,000 of costs related to storage, maintenance and insurance of the aircraft following the expiration of the lease. On March 1, 2019, the Southern District of New York Court denied Huntington’s motion for summary judgment. We initiated discovery; however, on May 16, 2019, the proceedings were stayed as a result of the Chapter 11 Cases.
Two purported class action complaints, Kokareva v. Bristow Group Inc., Case No. 4:19-cv-0509 and Lilienfield v. Bristow Group Inc., Case No. 4:19-cv-1064, were filed in the U.S. District Court for the Southern District of Texas (the “Southern District of Texas Court”) on February 14, 2019 and March 21, 2019, respectively. The complaints, which also name Jonathan E. Baliff and L. Don Miller as defendants, allege violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 arising out of the Company’s disclosures and alleged failure to make timely disclosure of inadequate monitoring control processes related to non-financial covenants within certain of its secured financing and lease agreements.  On May 17, 2019, the Southern District of Texas Court appointed BRS Investor Group as Lead Plaintiff and consolidated both actions under Kokareva v. Bristow Group Inc., Case No. 4:19-cv-0509. 
When the Company filed the Chapter 11 Cases on May 11, 2019, the litigation against the Company was automatically stayed.  The case was not automatically stayed against the individual defendants, but the Company intends to request that the stay also extend to the individual defendants.  On May 31, 2019, the Lead Plaintiff requested that the Southern District of Texas Court schedule an initial conference, and the defendants requested that any conference be postponed until after the Bankruptcy Court decides whether the stay should extend to the individual defendants.  The Southern District of Texas Court has not yet set a date for an initial conference.  The defendants believe that the claims are without merit and intend to vigorously defend against them.
On June 7, 2019, Marilyn DeVault filed a Stockholder Derivative Complaint against Thomas N. Amonett, Gaurdie Banister Jr., Ian A. Godden, Lori A. Gobillot, A. William Higgins, Thomas C. Knudson, Biggs C. Porter, Jonathan E. Baliff, Stephen A. King, Matthew Masters, David C. Gompert, Bruce H. Stover, L. Don Miller, and Brian J. Allman (the “Derivative Defendants”) in the United States District Court for the District of Delaware. The complaint alleges breaches of fiduciary duties and violations of Section 10(b) of the Securities Exchange Act of 1934 arising out of Company disclosures and failing to have adequate monitoring control processes related to non-financial covenants within certain of our secured financing and lease agreements. The complaint also alleges waste of corporate assets, gross mismanagement, and unjust enrichment.  The Derivative Defendants believe that the claims are without merit and intend to vigorously defend against them.
We operate in jurisdictions internationally where we are subject to risks that include government action to obtain additional tax revenue. In a number of these jurisdictions, political unrest, the lack of well-developed legal systems and legislation that is not clear enough in its wording to determine the ultimate application, can make it difficult to determine whether legislation may impact our earnings until such time as a clear court or other ruling exists. We operate in jurisdictions currently where amounts may be due to governmental bodies that we are not currently recording liabilities for as it is unclear how broad or narrow legislation may ultimately be interpreted. We believe that payment of amounts in these instances is not probable at this time, but is reasonably possible.
A loss contingency is reasonably possible if the contingency has a more than remote but less than probable chance of occurring. Although management believes that there is no clear requirement to pay amounts at this time and that positions exist suggesting that no further amounts are currently due, it is reasonably possible that a loss could occur for which we have estimated a maximum loss at September 30,December 31, 2018 to be approximately $5 million to $6$3 million.

Note 89 — TAXES
We estimate the full-year effective tax rate from continuing operations and apply this rate to our year-to-date income from continuing operations. In addition, we separately calculate the tax impact of unusual or infrequent items, if any. The tax impacts of such unusual or infrequent items are treated discretely in the quarter in which they occur. During the three months ended September 30,December 31, 2018 and 2017, our effective tax rate was 9.8%(38.4)% and (8.6)%57.5%, respectively, and during the sixnine months ended September 30,December 31, 2018 and 2017, our effective tax rate was 9.5%(2.1)% and (22.4)(2.7)%, respectively. The effective tax rates for the three and sixnine months ended September 30,December 31, 2018 and 2017 were impacted by net operating losses in certain foreign jurisdictions and valuation allowances against future realization of foreign tax credits.
The relationship between our provision for or benefit from income taxes and our pre-tax book income can vary significantly from period to period considering, among other factors, (a) the overall level of pre-tax book income, (b) changes in the blend of income that is taxed based on gross revenues or at high effective tax rates versus pre-tax book income or at low effective tax rates and (c) our geographical blend of pre-tax book income. Consequently, our income tax expense or benefit does not change proportionally with our pre-tax book income or loss. Significant decreases in our pre-tax book income typically result in higher effective tax rates, while significant increases in pre-tax book income can lead to lower effective tax rates, subject to the other factors impacting income tax expense noted above. The change in our effective tax rate excluding discrete items for the three and sixnine months ended September 30,December 31, 2018 compared to the three and sixnine months ended September 30,December 31, 2017 primarily related to changes in the blend of earnings taxed in relatively high taxed jurisdictions versus low taxed jurisdictions. Additionally, we increased our valuation allowance by $9.3$33.5 million and $0.2$2.1 million for the three months ended September 30,December 31, 2018 and 2017, respectively, and $10.3$43.8 million and $11.3$13.4 million for the sixnine months ended September 30,December 31, 2018 and 2017, respectively, which also impacted our effective tax rate.
As of September 30,December 31, 2018, there were $6.7$4.3 million of unrecognized tax benefits, all of which would have an impact on our effective tax rate if recognized.
On December 22, 2017, the president of the United States signed into law tax legislation commonly known as the Tax Cuts and Jobs Act (the “Act”). The Act includes numerous changes in existing U.S. tax law, including a permanent reduction in the U.S. federal corporate income tax rate from 35% to 21%. The rate reduction took effect on January 1, 2018. Further, the Act provides for a one-time “deemed repatriation” of accumulated foreign earnings of certain foreign corporations. Under U.S. generally accepted accounting principles, our net deferred tax liabilities are required to be revalued during the period in which the new tax legislation is enacted. We have made reasonable estimates forcompleted our analysis of the change in the U.S. federal corporate income tax rate and one-time “deemed repatriation”implications of accumulated foreign earnings. For the yearAct during the three months ended MarchDecember 31, 2018 our provision for income tax includedand recorded adjustments accordingly to previously reported provisional amounts for the revaluation of U.S. net deferred tax liabilities and the impact of the “deemed repatriation” of foreign earnings. The provisional amounts associated with the one-time “deemed repatriation” and the re-measurement of deferred tax assets and liabilities due to the reduction in the corporate income tax rate will be adjusted over time as we perform additional analysis based on recent guidance.amounts.
Certain provisions under the Act became applicable to us on April 1, 2018 and our income tax provision for the three and sixnine months ended September 30,December 31, 2018 includes the tax implications of these provisions. These provisions include Global Intangible Low-Taxed Income (“GILTI”), Base Erosion and Anti-Avoidance Tax (“BEAT”), Foreign Derived Intangible Income (“FDII”), and certain limitations on the deduction of interest expense and utilization of net operating losses.

The current estimates of our cash contributions to our defined benefit pension plans to be paid in fiscal year 2019 are $16.7$16.3 million, of which $8.5$12.7 million was paid during the sixnine months ended September 30,December 31, 2018. The weighted-average expected long-term rate of return on assets for our U.K. pension plans as of March 31, 2018 was 3.6%.
In October 2018, the U.K. High Court ruled that the U.K. defined pension schemes will be required to equalize for the effect of unequal guaranteed minimum pensions (“GMPs”) accrued between 1990 and 1997 by adjusting other non-GMP benefits. We recorded additional pension liability of $2.9 million as of December 31, 2018 related to this ruling that will be recorded as additional service cost over the future service period of approximately 20 years.
Incentive Compensation
Stock-based awards are currently made under the Bristow Group Inc. 2007 Long-Term Incentive Plan, as amended and restated on August 3, 2016 (the “2007 Plan”). A maximum of 10,646,729 shares of common stock are reserved. Awards granted under the 2007 Plan may be in the form of stock options, stock appreciation rights, shares of restricted stock, other stock-based awards (payable in cash or common stock) or performance awards, or any combination thereof, and may be made to outside directors, employees or consultants. As of September 30,December 31, 2018, 1,736,1411,811,843 shares remained available for grant under the 2007 Plan.
We have a number of other incentive and stock option plans which are described in Note 9 to our fiscal year 2018 Financial Statements.
Total stock-based compensation expense, which includes stock options and restricted stock, totaled $2.0$1.9 million and $2.4$2.2 million during the three months ended September 30,December 31, 2018 and 2017, respectively, and $3.7$5.7 million and $6.5$8.8 million for the sixnine months ended September 30,December 31, 2018 and 2017, respectively. Stock-based compensation expense has been allocated to our various regions.

During the sixnine months ended September 30,December 31, 2018, we awarded 400,788 shares of restricted stock at an average grant date fair value of $12.53 per share. Also during the sixnine months ended September 30,December 31, 2018, 593,129 stock options were granted. The following table shows the assumptions used to compute the stock-based compensation expense for stock options granted during the sixnine months ended September 30,December 31, 2018:
Risk free interest rate2.76%

Volatility62.8%
Dividend yield%
Weighted average exercise price of options granted$12.19 per option

During June 2018 and 2017, we awarded certain members of management phantom restricted stock which will be paid out in cash after three years. Additionally, during fiscal year 2018, we awarded 22,034 shares of restricted stock to a consultant, which vested in September 2018. We account for these awards as liability awards. As of September 30,December 31, 2018 and March 31, 2018, we had $1.6$0.4 million and $1.0 million, respectively, included in other liabilities and deferred credits on our condensed consolidated balance sheet accrued for these awards. Additionally, we recognizedchanges in general and administrativethe fair values of these liability awards reduced compensation expense on our condensed consolidated statement of operations $0.2 million and $0.3 million during the three months ended September 30, 2018 and 2017, and $0.8by $1.1 million and $0.4 million during the sixthree and nine months ended September 30,December 31, 2018, respectively, and increased compensation expense by $0.5 million and $0.9 million during the three and nine months ended December 31, 2017, respectively, related to these awards.

respectively.
Performance cash awards granted in June 2017 and 2018 have two components. One half of each performance cash award will vest and pay out in cash three years after the date of grant at varying levels depending on our performance in Total Shareholder Return against a peer group of companies. The other half of each performance cash award will be earned based on absolute performance in respect of improved average adjusted earnings per share for the Company over the three-year performance period beginning on April 1, 2017 and 2018, as applicable. Performance cash awards granted in June 2016 vest and pay out in cash three years after the date of grant at varying levels depending on our performance in Total Shareholder Return against a peer group of companies. These awards were designed to tie a significant portion of total compensation to performance. One of the effects of this type of compensation is that it requires liability accounting which can result in volatility in earnings. The liability recorded for these awards as of September 30December 31 and March 31, 2018 was $5.2$3.9 million and $7.7 million, respectively, and represents an accrual based on the fair value of the awards on those dates. The decrease in the liability during the sixnine months ended September 30,December 31, 2018 resulted from the payout in June 2018 of the awards granted in June 2015, partially offset by the value of the new awards granted in June 2018. Any changes in fair value of the awards in future quarters will increase or decrease the liability and impact results in those periods. The effect, either positive or negative, on future period earnings can vary based on factors including changes in our stock price or the stock prices of the peer group companies, as well as changes in other market and company-specific assumptions that are factored into the calculation of fair value of the performance cash awards.
Changes in the fair values of performance cash awards increasedreduced compensation expense by $0.1$1.3 million and $4.4$0.8 million during the three months ended September 30,December 31, 2018 and 2017, respectively, and reduced compensation expense by $0.2 million and increased compensation expense by $1.1 million and $1.4$0.6 million during the sixnine months ended September 30,December 31, 2018 and 2017, respectively.

Earnings per Share
Basic earnings per common share is computed by dividing income available to common stockholders by the weighted average number of shares of common stock outstanding during the period.

_____________
(1) 
Diluted loss per common share for three and sixnine months ended September 30,December 31, 2018 excludes a number of potentially dilutive shares determined pursuant to a specified formula initially issuable upon the conversion of our 4½% Convertible Senior Notes. The 4½% Convertible Senior Notes will be convertible, under certain circumstances, into cash, shares of our common stock or a combination of cash and our common stock, at our election. We have initially elected combination settlement. As of September 30,December 31, 2018 and March 31, 2018, the base conversion price of the notes was approximately $15.64, based on the base conversion rate of 63.9488 shares of common stock per $1,000 principal amount of convertible notes (subject to adjustment in certain circumstances). In general, upon conversion of a note, the holder will receive cash equal to the principal amount of the note and common stock to the extent of the note’s conversion value in excess of such principal amount. Such shares did not impact our calculation of diluted loss per share for the three and sixnine months ended September 30,December 31, 2018 as our average stock price during these periods did not meet or exceed the conversion requirements.
(2) 
Potentially dilutive shares issuable pursuant to our warrant transactions entered into concurrently with the issuance of our 4½% Convertible Senior Notes (the “Warrant Transactions”) were not included in the computation of diluted loss per share for the three and sixnine months ended September 30,December 31, 2018, because to do so would have been anti-dilutive. For further details on the Warrant Transactions, see Note 4 in our fiscal year 2018 Financial Statements.

Note 1213 — SUPPLEMENTAL CONDENSED CONSOLIDATING FINANCIAL INFORMATION
The Company has registered senior notes that the Guarantor Subsidiaries have fully, unconditionally, jointly and severally guaranteed. The following supplemental financial information sets forth, on a consolidating basis, the balance sheet, statement of operations, comprehensive income and cash flow information for Bristow Group Inc. (“Parent Company Only”), for the Guarantor Subsidiaries and for our other subsidiaries (the “Non-Guarantor Subsidiaries”). We have not presented separate financial statements and other disclosures concerning the Guarantor Subsidiaries because management has determined that such information is not material to investors. For further details on the registered senior notes, see Note 4 to the fiscal year 2018 Financial Statements.
The supplemental condensed consolidating financial information has been prepared pursuant to the rules and regulations for condensed financial information and does not include all disclosures included in annual financial statements, although we believe that the disclosures made are adequate to make the information presented not misleading. The principal eliminating entries eliminate investments in subsidiaries, intercompany balances and intercompany revenue and expense.
The allocation of the consolidated income tax provision was made using the with and without allocation method.

Note 13 — SUBSEQUENT EVENTS
Columbia AcquisitionSupplemental Condensed Consolidating Statement of Cash Flows
Stock Purchase AgreementOn November 9, 2018, Bear Acquisition I, LLC (“Purchaser”), a newly formed wholly owned subsidiary of the Company and the Company entered into a Stock Purchase Agreement (the “Purchase Agreement”) with Columbia Helicopters, Inc. (“Columbia”), the shareholders of Columbia (the “Sellers”), and a shareholder representative. The Purchase Agreement provides for the acquisition by the Purchaser of all of the issued and outstanding shares of Columbia (the “Columbia Acquisition”), on the terms and subject to the conditions set forth in the Purchase Agreement.Nine Months Ended December 31, 2017
The consideration to be paid by the Purchaser under the Purchase Agreement consists of $492.4 million in cash and shares of common stock of the Company, $0.01 par value (“Company Common Stock”), with an aggregate value of approximately $67.0 million calculated based on the volume weighted average price of the Company Common Stock for the five consecutive trading day period starting with the opening of the first primary trading session following the execution and public announcement of the Purchase Agreement, subject to an aggregate cap of approximately 6.2 million shares (the “Stock Consideration”), subject to adjustment as described in the Purchase Agreement.
The Purchase Agreement contains representations, warranties and covenants of the parties. The completion of the Columbia Acquisition is subject to the completion of certain conditions, including, but not limited to: the expiration of any waiting period applicable to the Columbia Acquisition under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, (“HSR”) the authorization for listing of the shares of Company Common Stock to be issued as Stock Consideration on the New York Stock Exchange, the completion of certain environmental testing, the continued employment of Steven E. Bandy as President and CEO of Columbia, the accuracy of the parties’ representations and warranties (including the absence of a “Material Adverse Effect” with respect to either party), and the receipt of other specified consents and approvals. The Purchase Agreement contains certain termination rights, including the right of either party to terminate the Purchase Agreement if the closing of the Columbia Acquisition (the “Closing”) has not occurred by April 9, 2019, subject to an additional marketing period. The Purchase Agreement also provides that, under specified circumstances where the conditions to Purchaser’s obligations to close the Columbia Acquisition have been satisfied but Purchaser has not consummated the Columbia Acquisition, Purchaser will be required to pay Columbia a termination fee of $20.0 million.
Stockholders AgreementIn connection with the Columbia Acquisition, the Company and certain of the Sellers entered into a Stockholders Agreement, which will become effective at the Closing. The Stockholders Agreement provides that such Sellers may not transfer the shares of Company Common Stock received as Stock Consideration for a period of 9 months following the Closing, subject to customary exceptions. Following the Closing, the Company has agreed to, among other things, prepare and file with the Securities and Exchange Commission (“SEC”) a shelf registration statement on Form S-3, or an amendment to an existing shelf registration statement, relating to the resale by the Sellers of the shares of Company Common Stock issued as Stock Consideration. The Sellers that are party to the Stockholders Agreement will also be subject to certain additional transfer restrictions with respect to their Company Common Stock. In addition, the Sellers that are party to the Stockholders Agreement have agreed to vote all of their shares of Company Common Stock in favor of all director nominees recommended by the Company Board, against any director nominees that have not been recommended by the Board, and in accordance with the Board’s recommendation on all other matters (except that such Sellers will not be required to vote in accordance with the Board’s recommendation with respect to matters that would result in any material change to the purpose or scope of the Company, any changes to constitutional documents that would materially alter the capital structure of rights as a common stockholder, or a merger of the Company or any of its significant subsidiaries to a third party, the sale or transfer of all or substantially all of the Company’s assets or dissolution). The Stockholders Agreement also includes standstill provisions that will restrict the Sellers that are party to the Stockholders Agreement from, among other things, nominating any directors, proposing any acquisition transaction relating to all or part of the Company, initiating any stockholder proposal, or acquiring, in the aggregate amongst the Sellers and during any consecutive twelve-month period, more than 2% of the Company’s outstanding voting securities through open-market purchases.
The Stockholders Agreement will terminate on the later of (1) the date which is two years following the date of the Stockholder Agreement and (2) the first period of twenty consecutive business days following the Closing during which the stockholders beneficially own, in the aggregate, less than 7.5% of the total voting power of the Company.
Financing ArrangementsIn connection with the Columbia Acquisition, on November 9, 2018, the Company and Purchaser entered into a commitment letter (the “Debt Commitment Letter”), pursuant to which Jefferies Finance LLC has committed to provide a portion of the financing for the Columbia Acquisition. The Debt Commitment Letter provides for a fully committed $360 million senior secured increasing rate bridge loan facility (the “Bridge Loan Facility”).

(Unaudited)


The commitments pursuant to the Bridge Loan Facility are subject to the satisfaction of certain conditions, including (1) the execution and delivery of definitive documentation with respect to the Bridge Loan Facility in accordance with the terms set forth in the Debt Commitment Letter, (2) the Closing, and (3) the absence of any material adverse effect with respect to Columbia’s business.
Also, on November 9, 2018, the Company entered into a Commitment Letter (the “Convertible Notes Commitment Letter”) with certain private investors (collectively, the “Note Purchasers”), whereby the Company has agreed to issue, and the Note Purchasers have agreed to purchase, a minimum of $135.0 million aggregate principal amount of a new series of convertible senior secured notes of the Company (the “Convertible Notes”). The Note Purchasers also have the option to purchase up to an additional $15 million of Convertible Notes. The Convertible Notes will be secured by a pledge of the common stock of Columbia held by the Company. In connection with such pledge, the Company will be required to obtain the consent of holders of the Company's 8.75% senior secured notes due 2023 to an amendment to the related indenture. The Convertible Notes have an initial conversion premium determined based on the three trading day volume weighted average price of the Company Common Stock over the period commencing following the announcement of such consent. In addition, the Company expects Columbia to issue warrants to purchase shares of the capital stock of Columbia in the event of certain events of bankruptcy, insolvency or reorganization with respect to the Company.
The Convertible Notes and the warrants will be issued in a private placement exempt from the registration requirements of the Securities Act, in reliance on the exemptions set forth in Section 4(a)(2) of the Securities Act. The closing of the private placement is subject to the satisfaction of certain conditions, including (1) the execution and delivery of definitive documentation with respect to the Convertible Notes in accordance with the terms set forth in the Convertible Notes Commitment Letter, (2) the Closing, (3) the receipt of the consent described above and (4) the absence of any material adverse effect with respect to Columbia’s business.
Subscription AgreementsIn connection with the Purchase Agreement, the Company entered into subscription agreements with certain employees of Columbia, pursuant to which the Company has agreed to issue and the employees have agreed to purchase an aggregate of $10.0 million worth of Company Common Stock (calculated based on the volume weighted average price of the Company Common Stock for the five consecutive trading day period starting with the opening of the first primary trading session following the execution and public announcement of the Purchase Agreement, subject to an aggregate cap of approximately 0.9 million shares, for the purpose of funding the Columbia Acquisition consideration) (the “Subscription Agreements”) at the Closing. The shares of Company Common Stock are subject to repurchase by the Company upon the occurrence of certain events of termination of employment within two years after the Closing. In addition, the Company agreed to award such employees at Closing restricted stock units under the Company’s 2007 Long Term Incentive Plan.
CEO Transition
On November 9, 2018, the Company announced the upcoming retirement of Jonathan E. Baliff. Thomas N. Amonett, Vice-Chairman of the Board of Directors of Bristow, has been appointed to serve as the interim President of the Company during the CEO transition process. The Corporate Governance and Nominating Committee of the Board of Directors is leading the search for a new CEO, with input from the Board of Directors and the support of an executive search firm.
Until Mr. Baliff’s retirement, he will focus on integration planning for the Columbia Acquisition. Mr. Baliff will resign from the Board of Directors concurrently with the effectiveness of his retirement.
The senior management of the Company will report directly to Mr. Amonett, who will work closely with Thomas C. Knudson, Chairman of the Board of Directors, to oversee operations. Mr. Baliff will continue to report to the Board of Directors.

Report of Independent Registered Public Accounting Firm
To the Stockholders and Board of Directors
Bristow Group Inc.:
Results of Review of Interim Financial Information
We have reviewed the condensed consolidated balance sheet of Bristow Group Inc. and subsidiaries (the Company) as of September 30,December 31, 2018, the related condensed consolidated statements of operations and comprehensive loss for the three-month and six-monthnine-month periods ended September 30,December 31, 2018 and 2017, the related condensed consolidated statements of cash flows for the six-monthnine-month periods ended September 30,December 31, 2018 and 2017, and the related condensed consolidated statements of changes in stockholders’ investment for the three-month and six-monthnine-month periods ended September 30,December 31, 2018, and the related notes (collectively, the consolidated interim financial information). Based on our reviews, we are not aware of any material modifications that should be made to the consolidated interim financial information for it to be in conformity with U.S. generally accepted accounting principles.
We have previously audited, in accordance with standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheet of the Company as of March 31, 2018, and the related consolidated statements of operations and comprehensive loss, stockholders’ investment and redeemable noncontrolling interest, and cash flows for the year then ended (not presented herein); and in our report dated May 23, 2018, except for the going concern, Note 1 related to the bankruptcy, restructuring support agreement and immaterial corrections to prior period financial information, and Note 4 for the short-term borrowings reclassification, and the restatement as to the effectiveness of internal control over financial reporting for the material weakness related to compliance with non-financial covenants underlying the Company’s secured financing and lease agreements, as to which the date is June 19, 2019, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of March 31, 2018, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.
Basis for Review Results
This consolidated interim financial information is the responsibility of the Company’s management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our reviews in accordance with the standards of the PCAOB. A review of consolidated interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Executive Overview
This Executive Overview only includes what management considers to be the most important information and analysis for evaluating our financial condition and operating performance. It provides the context for the discussion and analysis of the financial information that follows and does not disclose every item impacting our financial condition and operating performance. For a discussion of the Chapter 11 Cases, (as defined herein), please see Note 1 in the Explanatory Note and “Liquidity and Capital Resources —Financial Condition and Sources of Liquidity”“Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report.
On May 11, 2019 (the “Petition Date”), Bristow Group Inc. and its subsidiaries BHNA Holdings Inc., Bristow Alaska Inc., Bristow Helicopters Inc., Bristow U.S. Leasing LLC, Bristow U.S. LLC, BriLog Leasing Ltd. and Bristow Equipment Leasing Ltd. (together, the “Debtors”) filed voluntary petitions (the “Chapter 11 Cases”) in the United States Bankruptcy Court for the Southern District of Texas, Houston Division (the “Bankruptcy Court”) seeking relief under Chapter 11 of Title 11 of the United States Code (the “Bankruptcy Code”). The Debtors’ Chapter 11 Cases are jointly administered under the caption In re: Bristow Group Inc., et al., Main Case No. 19-32713. The Debtors continue to operate their businesses and manage their properties as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court.
During the Chapter 11 Cases, we expect our financial results to continue to be volatile as restructuring activities and expenses, contract terminations and rejections, and claims assessments significantly impact our consolidated financial statements. As a result, our historical financial performance is likely not indicative of our financial performance after the date of the filing of the Chapter 11 Cases. In addition, we have incurred significant professional fees and other costs in connection with preparation for the Chapter 11 Cases and expect that we will continue to incur significant professional fees and costs throughout our Chapter 11 Cases.
General
We are the leading global industrial aviation services provider based on the number of aircraft operated. We have a long history in industrial aviation services through Bristow Helicopters Ltd. (“Bristow Helicopters”) and Offshore Logistics, Inc., which were founded in 1955 and 1969, respectively. We have major transportation operations in the North Sea, Nigeria and the U.S. Gulf of Mexico, and in most of the other major offshore energy producing regions of the world, including Australia, Brazil, Canada, Russia and Trinidad. We provide private sector SAR services in Australia, Canada, Norway, Russia, Trinidad and the United States. We provide public sector SAR services in the U.K. on behalf of the Maritime & Coastguard Agency. We also provide regional fixed wing scheduled and charter services in the U.K., Nigeria and in Australia through our consolidated affiliates, Eastern Airways International Limited (“Eastern Airways”) andaffiliate Capiteq Limited, operating under the name of Airnorth. These operations support our primary industrial aviation services operations in those markets, creating a more integrated logistics solution for our customers. We also provided regional fixed wing scheduled and charter services in the U.K. through our consolidated affiliate Eastern Airways International Limited (“Eastern Airways”) until our disposal of Eastern Airways on May 10, 2019.
During the Current Period, we generated approximately 65%66% of our consolidated operating revenue from external customers from oil and gas operations, approximately 18% from U.K. SAR operations and approximately 16% from fixed wing services, including charter and scheduled airline services that support our global helicopter operations.
We conduct our business in one segment: industrial aviation services. The industrial aviation services segment operations are conducted primarily through two hubs that include four regions:
Europe Caspian,
Africa,
Americas, and
Asia Pacific.
We primarily provide industrial aviation services to a broad base of major integrated, national and independent offshore energy companies. Our customers charter our helicopters primarily to transport personnel between onshore bases and offshore production platforms, drilling rigs and other installations. To a lesser extent, our customers also charter our helicopters to transport time-sensitive equipment to these offshore locations. These customers’ operating expenditures in the production sector are the principal source of our revenue, while their exploration and development capital expenditures provide a lesser portion of our revenue. The customers for SAR services include both the oil and gas industry, where our revenue is primarily dependent on our customers’ operating expenditures, and governmental agencies, where our revenue is dependent on a country’s desire to privatize SAR and enter into long-term contracts. As of September 30,December 31, 2018, we operated 282277 aircraft (including 190191 owned aircraft and 9286 leased aircraft; 10 of the owned aircraft are held for sale) and our unconsolidated affiliates operated 114108 aircraft in addition to those aircraft leased from us.


The chart below presents (1) the number of aircraft in our fleet and their distribution among the regions of our industrial aviation services segment as of September 30,December 31, 2018; (2) the number of helicopters which we had on order or under option as of September 30,December 31, 2018; and (3) the percentage of operating revenue which each of our regions provided during the Current Period. For additional information regarding our commitments and options to acquire aircraft, see Note 78 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report.

The 114108 aircraft operated by our unconsolidated affiliates do not include those aircraft leased from us. Includes 4342 helicopters (primarily medium) and 22 fixed wing aircraft owned and managed by Líder Táxi Aéreo S.A. (“Líder”), our unconsolidated affiliate in Brazil included in the Americas region, and 4136 helicopters and seven fixed wing aircraft owned by Petroleum Air Services (“PAS”), our unconsolidated affiliate in Egypt included in the Africa region, and one helicopter operated by Cougar Helicopters Inc., our unconsolidated affiliate in Canada.Canada included in the Americas region.

This table does not reflect aircraft which our unconsolidated affiliates may have on order or under option.

The commercial aircraft in our consolidated fleet represented in the above chart are our primary source of revenue. To normalize the consolidated operating revenue of our commercial helicopter fleet for the different revenue productivity and cost, we developed a common weighted factor that combines large, medium and small commercial helicopters into a combined standardized number of revenue producing commercial aircraft assets. We call this measure Large AirCraft Equivalent (“LACE”). Our commercial large, medium and small helicopters, including owned and leased helicopters, are weighted as 100%, 50%, and 25%, respectively, to arrive at a single LACE number, which excludes fixed wing aircraft, unconsolidated affiliate aircraft, aircraft held for sale and aircraft construction in progress. We divide our operating revenue from commercial contracts relating to LACE aircraft, which excludes operating revenue from affiliates and reimbursable revenue, by LACE to develop a LACE rate, which is a standardized rate. Our historical LACE and LACE rate is as follows:

Our Strategy
Our goal is to further strengthen our market position as the leading industrial aviation services provider to the offshore energy industry and public and private sector SAR.globally. To do this, we will pursue efficiencies and new opportunities in our core markets, address oversupply and market saturation by diversifying our portfolio, and drive innovation throughout our businesses and industry.
We will continue to transform our business to create financial sustainability, defined as positive cash flow, reduced leverage and an ability to refinance fiscal year 2023 debt maturities in absence of an offshore market recovery as the timing of a recovery remains uncertain. Fiscal year 2019 priorities include: (1) safety improvements with a refresh of Target Zero; (2) revenue growth by being competitive in a short-cycle market; (3) cost efficiencies building on the success of fiscal year 2018; (4) improving financial returns on capital with improved aircraft utilization.
On November 9, 2018, we entered into a definitive agreement to acquire privately held Columbia for $560 million. We expect the complementary transaction to strengthen our operational and consolidated financial profile by delivering adjusted EBITDA and cash flow accretion; reducing consolidated net leverage; diversifying the combined company’s fleet and customer base; expanding our addressable market, especially in the U.S. government sector; and producing significant incremental revenue opportunities. For further details, see Note 13 in the “Notes to the Condensed Consolidated Financial Statements” include elsewhere in this Quarterly Report.
While we are well-positioned to take advantage of the beginning of an offshore investment cycle, continued innovation and greater cost efficiencies will be required beyond fiscal year 2019 as we move from sustainability to profitability. Specifically, we will continue to employ our “STRIVE” strategy as follows:
Sustain Target Zero Safety Culture. Safety will always be our number one focus. We continue to deliver Target Zerostrong operational safety performance with regard to our air accidentsacross the group and maintain a ground recordable injury rate that places us in the upper tier of our peer companies in oilfield services and aviation. We seek to continuously improve our safety systems and processes to allow us to become even safer and to build confidence in our industry and among our regulators with respect to the safety

of helicopter transportation globally. We recently completed a global survey of safety culture and organizational effectiveness with our employees reporting that despite the historic industry downturn for oil and gas, our Target Zero safety culture remains intact and strong, especially at the local base level.
Train and Develop our People. We continue to invest in employee training to ensure that we have the best workforce in the industry. We believe that the skills, talent and dedication of our employees are our most important assets, and we plan to continue to invest in them, especially in entry level learning, the continued control and ownership of certain training assets, and creation of leadership programming.
Renew Commercial Strategy and Operational Excellence. We are in the process of renewing both our commercial strategy to improve revenue productivity across our global markets and our operational strategy to serve our customers safely, reliably and efficiently. We believe that we need to renew these strategies in order to thrive in an economy that is undergoing long-term structural change. Our Europe and Americas hub structure has allowed us to achieve reductions in general and administrative expenses down to approximately 12% of revenue compared to 14% in fiscal year 2015. Further, we believe our hub structure allows us to take advantage of short-cycle work, which we define as short-term demand requests from our oil and gas customers for contracts measured in months rather than years.
Improve Balance Sheet and Return on Capital. We continually seek to improve our balance sheet and liquidity and reduce our capital costs, with a goal of reduced financing leverage (including lower levels of debt and leases), and a return to profitability and improvement of return on invested capital. To achieve this we have historically practiced the principal of prudentprofitability. In order to strengthen our balance sheet management and have proactively managed our liquidity position with cash flows from operations, as well as external financings. These external financings have includedachieve a more sustainable debt profile, we filed for Chapter 11 protection on the use of operating leases for a target of approximately 35% of our LACE. The target recognizes that we will have variability above or below the target of approximately 5% of our LACE due to timing of leases, purchases, disposals and lease terminations. As of September 30, 2018, commercial helicopters under operating leases accounted for 39% of our LACE. See “Liquidity and Capital Resources —Financial Condition and Sources of Liquidity” included elsewhere in this Quarterly Report for further discussion of our capital structure and liquidity.
Petition Date.
Value Added Acquisitions and Divestitures. We intend to pursue value-added acquisitions with a focus on oil and gas transportation and search and rescue that not just make us bigger but better; that generate cost efficiencies that position us to thrive in an economy that is undergoing long-term structural change. We may also divest portions of our business or assets to narrow our product lines and reduce our operational footprint to reduce leverage and improve return on capital.capital and liquidity. We also intend to continue to utilize portfolio and fleet optimization. Consistent with our ongoing process to rationalize and simplify our business and global aircraft fleet, we sold 11 aircraft for proceeds of $48.3 million during fiscal year 2018 and sold three aircraft during the Current Period for proceeds of $8.1 million. We currently haveAs of December 31, 2018, we had ten aircraft held for sale and the average age of our fleet is approximately ten years. Additionally, our critical short and long-term goal is to significantly reduce our aircraft rent expense. Since April 1, 2017, we have returned sixeleven Airbus H225s and sixnine Sikorsky S-92s to lessors. We intend to further reduce aircraft rent expense through lease returns as partAlso, we disposed of our ongoing strategy to return to profitability. Also, discussed above,Eastern Airways on November 9, 2018, we entered into a definitive agreement to acquire privately held Columbia for $560 million which we believe is a significant step forward in terms of growing our diversified industrial aviation business.
Execute on Bristow Transformation. Our Europe and Americas hub structure has allowed for global alignment with faster local market response and increased cost efficiency. Also, as discussed elsewhere in this Quarterly Report, we reached agreements with OEMs during fiscal year 2018 to achieve $136 million in recoveries.

Market Outlook
Our core business is providing industrial aviation services primarily to the worldwide oil and gas industry. We also provide public and private sector SAR services and fixed wing transportation services. Our global operations and critical mass of helicopters provide us with geographic and customer diversity which helps mitigate risks associated with a single market or customer. Additionally, the announced signing of an agreement to acquire Columbia is a significant step forward in terms of growing our diversified industrial aviation business and strengthening our consolidated financial position.
The oil and gas business environment has experienced a significant downturn beginning duringvolatility since fiscal year 2015. Brent crude oil prices declined from approximately $106 per barrel as of July 1, 2014 to a low of approximately $26 per barrel in February 2016, with an increase2016. A recovery in Brent crude oil prices followed to approximately $73$77 per barrel as of September 30,June 27, 2018 with another decline to approximately $44 per barrel as of December 27, 2018. Brent crude oil prices were approximately $45 per barrel as of December 31, 2018. The decrease in oil prices beginning in fiscal year 2015 was driven by increased global supply primarily from unconventional oil resources in the U.S. Permian Basin and forecasts of reduced demand for crude oil resulting from weaker global economic growth in many regions of the world. The oil price decline negatively impacted the cash flow of our customers and resulted in their implementation of measures to reduce operational and capital costs, negatively impacting helicopter activity beginning in fiscal year 2015. These cost reductions have continued into fiscal year 2019 and have impacted both the offshore production and the offshore exploration activity of our customers, with offshore production activity being impacted to a lesser extent.customers. The largest share of our revenue relates to oil and gas production andproduction; however, our largest contract, the contract with the U.K. Department for Transport to provide public sector SAR services for all of the U.K. (the “U.K. SAR contract”), is not directly impacted by declining oil prices. However, the significant drop in the price of crude oil resulted in the rescaling, delay or cancellation of planned offshore projects which has negatively impacted our operations and could continue to negatively impact our operations in future periods.
The oil price environment is showing signs of stabilizing with crude oil prices at levels not seen sinceTo further reduce costs and make offshore drilling more financially attractive, the end of calendar year 2014. We are seeing an increase in offshore market activity off of a very low base level with an increased number of working floaters and jackups in our core markets, including the U.S. Gulf of Mexico and the North Sea. There have also been significant increases in front-end engineering and design awards that, along with the stabilization of tie-back work and floating production storage and offloading unit utilization, has historically been a leading indicator of increased offshore activity. The helicopter transportation industry is benefiting from relatively low day rates for rigs, whichimplementing technology-driven solutions that could result in turn reduces ourincreased transportation needs initially but could result in decreased activity once complete. Recently, we have seen opportunities in market share gains rather than increased activity. Our oil and gas customers’ costsmarkets remain competitive as material cost reductions and generates increasedtechnological improvements have taken place in the offshore supply chain. The continued volatility of oil prices combined with the excess supply of aircraft could continue to impact the price and demand for offshore transportation like helicopters. Our success in reducing costshelicopters and our faster hub response has made us more competitive, and we are gaining market share in this new environment for short-cycle requirements created by the changing market; however, we are uncertain asmay continue to whether this increased activity will lead to a recovery in offshore spending, and an extended period of reduced offshore spending may have a material impact on our financial position, cash flow and results of operations.
The SAR market is continuing to evolve and we believe further outsourcing of public SAR services to the private sector will continue in the future, although the timing of these opportunities is uncertain. The customers for our SAR services include both the oil and gas industry and governmental agencies. We are pursuing other public and oil and gas SAR opportunities for multiple aircraft in various jurisdictions around the globe and other non-SAR government aircraft logistics opportunities.
Like many of our competitors and other service providers to exploration and production companies, we responded to the constraints in the market during the past four years by implementing cost efficiencies both in our global operations as well as in our corporate headquarters, comprehensively reviewing operational and commercial dealings, exploring value-additive acquisitions and dispositions and developing strategic initiatives. We pursued a strategy of maximizing liquidity and financial flexibility through asset-level borrowings and secured equipment lease transactions. Together with revenue from operations, this additional liquidity allowed us to service our debt and provided a runway to maintain operations through the downturn.

Additionally, we have takentook the following actions in an effort to address the downturn:
We continue to seek ways to operate more efficiently in the current market and work with our customers to improve the efficiency of their operations. In early fiscal year 2018, we took additional steps to increase cost efficiency by optimizing our operations around two primary geographical hubs in key areas of our business, Europe and the Americas.
We increased our financial flexibility by entering into new secured equipment financings that resulted in aggregate proceeds of $630 million funded in fiscal years 2017 and 2018. Additionally, in fiscal year 2018, we completed the sale of $143.8 million of the 4½% Convertible Senior Notes due 2023 (the “4½% Convertible Senior Notes”) and $350 million of the 8.75% Senior Secured Notes.Notes due 2023 (the “8.75% Senior Secured Notes”). In April 2018, we entered into a new ABL Facilityasset-backed revolving credit facility (the “ABL Facility”) as discussed in Note 45 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report and under “— Recent Events” below.
We worked with our original equipment manufacturers (“OEMs”) to defer approximately $190 million of capital expenditures relating to fiscal years 2018 through 2020 into fiscal year 2020 and beyond and more recently deferred approximately $100 million in capital expenditures for fiscal years 2019 to 2023 into fiscal year 2024 and beyond. We achieved $136 million in cost recoveries from OEMs related to ongoing aircraft issues, of which $125 million was recovered in fiscal year 2018 and $11 million was recovered in May 2018.
We took significant steps to reduce general and administrative costs that included downsizing our corporate office and the size of our senior management team. Consistent with our STRIVE strategy, we are better positioned to win contracts because we are a more nimble, regionally focused and cost efficient business.
In August 2017, we suspended our quarterly dividend as part of a broader plan of reducing costs and improving liquidity. By suspending this $0.07 per share quarterly dividend, we expect to preserve approximately $10 million of cash annually.

Ultimately, however, given the continuing challenges in the offshore oil and gas industry and other matters impacting liquidity, the rate at which our cash position was declining began to increase, and we evaluated our strategic alternatives for the benefit of all our stakeholders, including our customers, employees, creditors and other investors. The fundamental shifts in the energy markets and in particular, offshore spending, have required us to re-think the strategic business plan to restructure with an eye toward an inevitable consolidation in the market for helicopter services. While we have maintained our leading market share, industry demand has declined precipitously, rending existing business models unsustainable and creating substantial overcapacity in the marketplace.
On the Petition Date, the Debtors filed the Chapter 11 Cases in the Bankruptcy Court seeking relief under Chapter 11 of the Bankruptcy Code. The Debtors’ Chapter 11 Cases are jointly administered under the caption In re: Bristow Group Inc., et al., Main Case No. 19-32713. The Debtors continue to operate their businesses and manage their properties as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court.
Recent Events
Restructuring Support Agreement — On May 10, 2019, we entered into a restructuring support agreement (the “RSA”) with (i) certain holders (the “Supporting Secured Noteholders”) of the 8.75% Senior Secured Notes and (ii) the guarantors of the 8.75% Senior Secured Notes, to support a restructuring of the Company (the “Restructuring”) on the terms set forth in the term sheet contained in an exhibit to the RSA (the “Restructuring Term Sheet”). The RSA contemplated the filing of the Chapter 11 Cases to implement the Restructuring pursuant to a Chapter 11 plan of reorganization (the “Plan”) and the various related transactions set forth in or contemplated by the Restructuring Term Sheet, the DIP Term Sheet (as defined herein) and the other restructuring documents attached to the RSA.
Pursuant to the terms of the RSA and the Restructuring Term Sheet:
holders of claims arising from the 8.75% Senior Secured Notes will receive their pro rata share of a percentage of the equity interests (the “Reorganized Equity”) of the Company, as reorganized pursuant to and under the Plan, equal to 100% minus the Unsecured Notes Reorganized Equity percentage (subject to dilution from the MIP and the Rights Offering (each as defined herein));
if the class of holders of claims (the “Unsecured Notes Claims”) arising from the 6¼% Senior Notes due 2022 and the 4½% Convertible Senior Notes (together, the “Unsecured Notes”) accepts the Plan, the holders of Unsecured Notes Claims will receive their pro rata share of the Reorganized Equity (subject to dilution from the MIP and the Rights Offering) in an amount (the “Consensual Unsecured Notes Reorganized Equity”) to be agreed upon by the Company and the holders of at least 66 2/3% of the aggregate principal amount of the 8.75% Senior Secured Notes obligated under the RSA and which must include at least two members of the Secured

Notes Ad Hoc Group (as defined herein) (the “Required Consenting Noteholders”) and any other rights or recovery that may be agreed upon by the Company and the Required Consenting Noteholders; and if the class of holders of Unsecured Notes Claims does not accept the Plan, the holders of Unsecured Notes Claims will receive their pro rata share of the percentage of the Reorganized Equity determined by the Bankruptcy Court to satisfy the best interests test;
if the class of holders of general unsecured claims that rank pari passu with the Unsecured Notes Claims (“Pari General Unsecured Claims”) votes in favor of the Plan, the holders of Pari General Unsecured Claims will receive their pro rata share of the Consensual Unsecured Notes Reorganized Equity; and if the class of holders of Pari General Unsecured Claims does not vote in favor of the Plan, the holders of Pari General Unsecured Claims will receive their pro rata share of the percentage of the Reorganized Equity determined by the Bankruptcy Court to satisfy the best interests test;
holders of claims under the 2019 Term Loan (as defined herein) will be repaid in cash in full or be reinstated;
holders of claims under the DIP Facility (as defined herein) will be paid in cash in full, provided that, the DIP Facility may be converted on a dollar-for-dollar basis into the Exit Facility (as defined herein);
an ad hoc group of holders of the 8.75% Senior Secured Notes (the “Secured Notes Ad Hoc Group”) has agreed to backstop a $200 million new money rights offering of the Reorganized Equity (the “Rights Offering”), pursuant to which participants will receive rights to purchase a percentage of the Reorganized Equity at a discount to the Plan equity value to be agreed upon by the Company and the Required Consenting Noteholders;
up to 10% of the Reorganized Equity on a fully diluted basis will be reserved for the MIP Reorganized Equity pursuant to a Management Incentive Plan (“MIP”) acceptable to the Required Consenting Noteholders; and
any exit financing for the Company will be in an amount and structure to be determined (the “Exit Facility”).
The RSA contains certain covenants on the part of each of the Company and the Supporting Secured Noteholders, including limitations on the Supporting Secured Noteholders’ ability to pursue alternative transactions, commitments by the Supporting Secured Noteholders to vote in favor of the Plan and commitments of the Company and the Supporting Secured Noteholders to negotiate in good faith to finalize the documents and agreements governing the Plan. The RSA also provides for certain conditions to the obligations of the parties and for termination upon the occurrence of certain events, including without limitation, the failure to achieve certain milestones and certain breaches by the parties under the RSA.
Term Loan AgreementOn May 10, 2019, the Company entered into a Term Loan Credit Agreement, dated the same date (the “Term Loan Agreement”), by and among the Company and Bristow Holdings Company Ltd. III (“BHC III”), as borrowers, certain subsidiaries of the Company as guarantors party thereto, the lenders from time to time party thereto (initially, certain holders of the 8.75% Senior Secured Notes), and Ankura Trust Company, LLC, as administrative agent, for a senior secured term loan of $75 million (the “2019 Term Loan”). Immediately upon entering into the Term Loan Agreement, and prior to the Petition Date, the Company and BHC III borrowed the full amount thereunder, the net proceeds of which may be used only in compliance with a cash flow forecast required pursuant to the terms of the Term Loan Agreement, which the Company expects will be used for general corporate purposes, including to fund the working capital and liquidity requirements of the Company during the pendency of the Chapter 11 Cases. The full principal amount of the 2019 Term Loan is due May 10, 2022. At the Company’s election, borrowings under the 2019 Term Loan will bear interest at either (x) the Eurodollar Rate (as defined in the Term Loan Agreement) plus 7% or (y) the Base Rate (as defined in the Term Loan Agreement) plus 6%. The initial borrowings under the 2019 Term Loan will be Eurodollar Rate loans with monthly interest payments. The 2019 Term Loan is secured by a first lien on certain specified collateral, including, among other things, equity pledges of 35% of the equity interests in certain of the Company’s first-tier foreign subsidiaries (the remaining 65% of such entities have been previously pledged under the 8.75% Senior Secured Notes), 100% of the equity of BHC III and Bristow International Panama S. de RL, and two newly formed special-purpose vehicles, as well as a junior lien on certain collateral securing the 8.75% Senior Secured Notes. The borrowers have the option in connection with the consummation of a Reorganization Plan (as defined in the Term Loan Agreement) that is satisfactory to the lenders to require that the 2019 Term Loan be converted into equity of the Company upon consummation of such Reorganization Plan, subject to certain conditions. The Term Loan Agreement contains customary pre-payment requirements.
The Term Loan Agreement contains certain customary negative covenants that, among other things, restrict, subject to certain exceptions, the Company’s and its subsidiaries’ incurrence of additional indebtedness or liens, mergers, dispositions of assets, investments, restricted payments, modifications to material agreements, transactions with affiliates and fundamental changes. In addition, the Term Loan Agreement requires that, on the delivery of each Variance Report (as defined in the Term Loan Agreement), total operating disbursements and total receipts of the Company and its subsidiaries for certain specified periods shall not exceed (with respect to disbursements) or be less than (with respect to total receipts) the aggregate amount forecasted therefor for such

period by more (with respect to disbursements) or less (with respect to total receipts) than a specified percentage of the forecasted amount. The Term Loan Agreement also contains customary affirmative covenants and customary representations and warranties.
The Term Loan Agreement specifies certain customary events of default, including, among others, failure to pay principal or interest on the 2019 Term Loan when due, the breach of representations or warranties in any material respect, non-performance of other covenants and obligations, judgments, the occurrence of certain ERISA events and certain change of control events. The filing of the Chapter 11 Cases neither constitutes an event of default nor accelerates the maturity of the Company’s indebtedness under the Term Loan Agreement.
Debtor-in-Possession Commitment LetterIn connection with the Chapter 11 Cases and pursuant to a Commitment Letter, dated May 10, 2019, from the lenders party thereto and agreed to by the Company and BHC III (together, the “DIP Borrowers”), the Secured Notes Ad Hoc Group has agreed to provide the DIP Borrowers with a superpriority senior secured debtor-in-possession credit facility (the “DIP Facility”) on the terms set forth in the DIP Facility Term Sheet attached thereto (the “DIP Term Sheet”). The DIP Term Sheet provides that, among other things, the DIP Facility shall be comprised of loans in an aggregate principal amount of $75.0 million. The availability of the DIP Facility is subject to certain conditions and milestones, including approval by the Bankruptcy Court, which has not been obtained at this time.
Going Concern — The Company’s liquidity outlook has recently changed resulting in substantial doubt about the Company’s ability to continue as a going concern. In addition, each of the commencement of the Chapter 11 Cases and the delivery of the Amended 10-K with a going concern qualification or explanation constituted an event of default under certain of our secured equipment financings, giving those secured equipment lenders the right to accelerate repayment of the applicable debt, subject to Chapter 11 protections, and triggering cross-default and/or cross-acceleration provisions in substantially all of our other debt instruments should that right to accelerate repayment be exercised. The Company expects to continue operations in the normal course during the pendency of the Chapter 11 Cases. The condensed consolidated financial statements included herein have been prepared on a going concern basis of accounting, which contemplates continuity of operations, realization of assets, and satisfaction of liabilities and commitments in the normal course of business. The condensed consolidated financial statements do not include any adjustments that might result from the outcome of the going concern uncertainty.
Eastern Airways and Humberside Airport — Bristow Helicopters, an indirect consolidated affiliate of the Company, together with its legal and financial advisors, pursued various transactions to exit the Eastern Airways business, which made negative contributions to our Adjusted EBITDA in each of the last three fiscal years, including pursuing a sales process with several third parties over an extended period. On May 10, 2019, Bristow Helicopters completed the sale of all of the shares of Eastern Airways to Orient Industrial Holdings Limited (“OIHL”), an entity affiliated with Mr. Richard Lake, pursuant to a Sale and Purchase Agreement (the “EAIL Purchase Agreement”). Pursuant to the EAIL Purchase Agreement and related agreements, Bristow Helicopters contributed approximately £17.1 million to Eastern Airways as working capital, OIHL acquired Eastern Airways, Bristow Helicopters retained its controlling ownership of the shares in Humberside International Airport Limited that it previously held through Eastern Airways and certain intercompany balances between Bristow Helicopters and Eastern Airways were written off. As a result of the transaction, OIHL now owns and operates Eastern Airways, which had previously operated as a separate unit within Bristow Group, and Bristow Helicopters maintains its controlling interest in Humberside Airport, from which Bristow Helicopters provides U.K. search and rescue services and Eastern Airways maintains its operations.
The EAIL Purchase Agreement contained customary representations and warranties. OIHL agreed to certain covenants with respect to non-solicitation of directors, officers or employees of Bristow Helicopters for a period of 12 months. Pursuant to the terms of the EAIL Purchase Agreement, Bristow Helicopters has the right to appoint an observer to the board of directors of Eastern Airways for an initial period of 12 months following the sale. Eastern Airways also agreed to provide certain transition services for a minimum of 12 months from the date of the completion of the transaction.
Deferral of Purchase of H175s — On May 1, 2019, we entered into an amendment to our agreement with Airbus Helicopters for the purchase of 22 H175 helicopters which includes five aircraft that can be cancelled by us prior to the delivery dates. Pursuant to the amendment, the parties mutually agreed to postpone the delivery dates for such helicopters for 18 months from the previous schedule with the first three helicopters now scheduled for delivery in the second half of fiscal year 2022. The postponement in deliveries resulted in various amendments to the payment terms under the purchase agreement including the deferral of approximately $110.0 million in capital expenditures scheduled for fiscal years 2019 to 2023 into fiscal years 2024 and beyond. Our capital commitments related to these H175 helicopters now total approximately $14.0 million for fiscal years 2020 and 2021. In connection with this amendment, the overall purchase price of these helicopters has been increased by $18.4 million to account for inflation.

CEO Transition — On November 9, 2018, the Company announced the upcoming retirement of Jonathan E. Baliff, who served as President and Chief Executive Officer of the Company. Mr. Baliff stepped down from the position of President effective November 9, 2018, while continuing to serve as Chief Executive Officer. Thomas N. Amonett, Vice-Chairman of the Board of Directors of Bristow (the “Board”), was appointed to serve as the interim President of the Company during the CEO transition process. On February 11, 2019, the Company entered into a Retirement and Consulting Agreement (the “Retirement and Consulting Agreement”) with Mr. Baliff. Under the Retirement and Consulting Agreement, Mr. Baliff ceased to serve as Chief Executive Officer of the Company and resigned from the Board effective February 28, 2019. Effective upon Mr. Baliff’s retirement and until the appointment of a new Chief Executive Officer, the Board named Mr. Amonett, the Vice-Chairman of the Board and interim President of the Company, to the additional role of interim Chief Executive Officer.
On March 1, 2019, the Company announced that L. Don Miller, Senior Vice President and Chief Financial Officer of the Company, had been appointed to succeed Mr. Baliff as President and Chief Executive Officer of the Company, effective as of the close of business on February 28, 2019. Mr. Miller joined the Board concurrently with the effectiveness of his appointment as President and Chief Executive Officer. Mr. Amonett, who has been serving as the interim President of the Company, was appointed to the role of Executive Vice Chairman of the Board, effective upon the effectiveness of Mr. Miller’s appointment. Brian J. Allman, Vice President and Chief Accounting Officer of the Company, was appointed to succeed Mr. Miller as Senior Vice President and Chief Financial Officer.

Columbia AcquisitionTransaction — On November 9, 2018, we entered into a definitive agreement to acquire privately held Columbia Helicopters Inc. (“Columbia”) for $560 million. Founded$496.75 million in 1957 by Wes Lemattacash and headquartered6.2 million shares of common stock of the Company. On February 11, 2019, we announced that Bristow and Columbia had mutually agreed to terminate our agreement to acquire Columbia. In connection with the termination, we paid $20 million to Columbia. Bristow, Columbia and Columbia’s shareholders agreed to release each other from all claims in Aurora, Oregon, Columbia isconnection with the leader in heavy-lift helicopter operationspurchase agreement and trusted expert in maintenance, repair and overhaul services, with global operations servicing end-markets that include defense, firefighting, onshore oil & gas, infrastructure and forestry.the related transactions. For further details, see Note 132 in the “Notes to the Condensed Consolidated Financial Statements” includeincluded elsewhere in this Quarterly Report.
Brexit — In a referendum held on June 23, 2016, voters in the U.K. approved the exit of the U.K. from the E.U. On March 29, 2017, the U.K. government commenced the exit process under Article 50 of the Treaty of the European Union by notifying the European Council of the U.K.’s intention to leave the E.U. This notification started a two-year time period that ended on March 29, 2019 for the U.K. and the remaining E.U. Member States to negotiate a withdrawal agreement. The U.K. and the E.U. were unable to negotiate a formal withdrawal agreement, and the Brexit date was extended until April 12, 2019 and further extended until October 31, 2019, although Brexit may become effective before such date under certain specified circumstances. Negotiations remain ongoing to determine the future terms of the U.K.’s relationship with the E.U. The impact on the Company’s business as a result of Brexit will depend, in part, on the outcome of tariff, trade, regulatory and other negotiations.
As a result of the referendum, the global markets and currencies have been adversely impacted, including a sharp decline in the value of the British pound sterling as compared to the U.S. dollar. Volatility in exchange rates resulting from Brexit is expected to continue in the short term as the U.K. negotiates its exit from the E.U. In addition, Brexit could create uncertainty with respect to the legal and regulatory requirements to which we and our customers in the U.K. are subject and lead to potentially divergent national laws and regulations as the U.K. determines which E.U. laws to replace or replicate, and those laws and regulations may be cumbersome, difficult or costly in terms of compliance. Any of these effects of Brexit, among others, could have a material adverse effect on our current business and future growth.
Loss on impairment — Prior to the three months ended September 30, 2018, we had been actively marketing our H225 aircraft with the expectation of a substantial return of the aircraft to oil and gas service. However, market conditions and more significantly, the recent development of alternative opportunities outside of our traditional oil and gas service for our H225 aircraft and our decision to pursue those opportunities during the three months ended September 30, 2018, indicateindicated a substantial return to oil and gas service within our operations iswas not likely. Therefore, during the three months ended September 30, 2018, we concluded that cash flows associated with our H225 helicopters arewere largely independent from the cash flows associated with the remainder of our oil and gas related property and equipment (“oil and gas asset group”) and should be tested for impairment as a stand-alone asset group. In accordance with Accounting Standard Codification (“ASC”) 360-10, we performed an impairment analysis for our stand-alone H225 asset group and determined that the forecasted cash flows over the remaining useful life of the asset group were insufficient to recover the carrying value of the asset group. We determined the fair value of the H225 asset group to be $116.4 million and recorded an impairment charge of $87.5 million.million during the three months ended September 30, 2018. In addition, we performed a review of our H225 aircraft related inventory and recorded an impairment charge of $8.9 million during the three months ended September 30, 2018 to record the inventory at the lower of cost or net realizable value.

 The removal of the H225 aircraft from our oil and gas asset group and changes in our forecasted cash flows for that asset group during the three months ended September 30, 2018 indicated the need for the performance of a recoverability analysis of the oil and gas asset group. In accordance with Accounting Standard CodificationASC 360-10, we estimate future undiscounted cash flows to test the recoverability of our oil and gas asset group, which largely consists of our oil and gas related held for use aircraft. The determination of estimated future undiscounted cash flows required us to use significant unobservable inputs, including assumptions related to projected demand for services, rates and anticipated aircraft disposal values. We determined that the estimated future undiscounted cash flows exceeded the carrying value for our oil and gas asset group as of September 30, 2018, and no impairment was recorded on these assets. Future declines in operating performance, aircraft disposal values, anticipated business outlook, or projected aircraft deliveries currently accounted for as construction in progress may reduce our estimated future undiscounted cash flows and result in impairment of our oil and gas asset group.
 In addition, changes in our forecasted cash flows during the Current Quarterthree months ended September 30, 2018 indicated the need for the performance of a recoverability analysis for the airline related assets of Eastern Airways. In accordance with Accounting Standard CodificationASC 360-10, we estimate future undiscounted cash flows to test the recoverability of the airline related assets of Eastern Airways for potential impairment. In accordance with Accounting Standard CodificationASC 360-10-35, we estimate future undiscounted cash flows to test the recoverability of the assets, which largely consists of our held for use aircraft and related rotable spare parts. The determination of estimated future undiscounted cash flows required us to use significant unobservable inputs, including assumptions related to projected demand for services and rates. We determined that the estimated future undiscounted cash flows were below the carrying value for our airline related assets of Eastern Airways as of September 30, 2018.  We determined the fair value of the asset group to be $20.5 million and recorded an impairment charge of $17.5 million.million during the three months ended September 30, 2018.  As part of our impairment review of the airline assets of Eastern Airways during the three months ended September 30, 2018, we recorded impairments of $3.0 million related to the remaining intangible assets and $0.3 million related to inventory.
No further triggers to review our assets for impairment exist as of December 31, 2018.
ABL Facility — On April 17, 2018, two of our subsidiaries entered into anthe ABL Facility as discussed in Note 45 in the “Notes to the Condensed Consolidated Financial Statements” includeincluded elsewhere in this Quarterly Report.
Tax Cuts and Jobs Act — On December 22, 2017, the president of the United States signed into law tax legislation commonly known as the Tax Cuts and Jobs Act (the “Act”). The Act includes numerous changes in existing U.S. tax law, including (1) reducing the U.S. federal corporate income tax rate from 35% to 21%; (2) requiring companies to pay a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries; (3) generally eliminating U.S. federal income taxes on dividends from foreign subsidiaries; (4) requiring a current inclusion in U.S. federal taxable income of certain earnings of controlled foreign corporations; and (5) eliminating the corporate alternative minimum tax (“AMT”) and changing how existing AMT credits can be realized. The Act also includes the following provisions, among others, that became applicable to us on April 1, 2018: (1) creation of a new minimum tax on base erosion and anti-abuse; (2) creation of additional limitations on deductible business interest expense; and (3) creation of additional limitations on the utilization of net operating loss carryforwards.

In December 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”), which addresses how a company recognizes provisional amounts when a company does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete its accounting for the effect of the changes in the Act.tax legislation commonly known as the Tax Cuts and Jobs Act (the “Act”). The measurement period ends when a company has obtained, prepared and analyzed the information necessary to finalize its accounting, but cannot extend beyond one year. For the year ended March 31, 2018, our provision for income taxes includes the impact of decisions regarding the various impacts of tax reform and related disclosures.December 22, 2018. Consistent with guidance in SAB 118, for fiscal yearduring the three months ended December 31, 2018, we recordedmade the following adjustments to the provisional amounts foramounts: (1) an additional $19.0 million of benefit from the revaluation of net deferred tax liabilities to reflect the impact of the change in the tax rate, (2) $30.7 million of additional expense related to the one-time transition tax on undistributedcertain unrepatriated earnings of $52.9 million, which was partially offset byforeign subsidiaries, and (3) a valuation allowance against our foreign tax credits of $22.6 million. Also in fiscal year 2018, we recorded $53.0$30.4 million tax benefit asresulting from unfavorable guidance recently released. As a result, of the revaluationwe utilized $121.5 million of our existing net deferredoperating losses in lieu of foreign tax liabilities. Additional details regardingcredits. We believe the Act and the impact on us are provided in Note 8provisions included in the “Notesnew guidance adversely impact our ability to Consolidated Financial Statements” included inbenefit from our 2018 Annual Report. 
We are continuing to analyze guidance as it becomes available to determine the overall impact. Any adjustments recorded to the provisional amounts will be included in income from operations as an adjustment to our fiscal year 2019 financial statements.existing foreign tax credit carryforwards.
Fleet updates — As previously reported, on April 29, 2016, another company’s EC 225LP (also known as an H225LP) model helicopter crashed near Turøy outside of Bergen, Norway resulting in the European Aviation Safety Agency (“EASA”) issuing airworthiness directives prohibiting flight of H225LP and AS332L2 model aircraft. On July 20, 2017, the U.K. CAA and NCAA issued safety and operational directives which detail the conditions to apply for the safe return to service of H225LP and AS332L2 model aircraft, where operators wish to do so. On July 5, 2018, the Accident Investigation Board Norway issued its final investigation report on the accident. The report cited a fatigue fracture within the epicyclic module of the main gear box as the cause of the accident, and issued safety recommendations in a number of areas, including gearbox design and certification requirements, failure tolerance, and continued airworthiness of the AS332L2 and the H225LP helicopters. We continue not to operate for commercial purposes our 21 H225LP model aircraft, and we are carefully evaluating next steps for the H225LP model aircraft in our operations worldwide, with the safety of passengers and crews remaining our highest priority. Recent third-party market transactions and the development of alternative opportunities outside of our traditional oil and gas services for our H225 aircraft indicateindicated a substantial return to oil and gas service within our operations iswas not likely. See Loss on Impairment above for further details.
Separately, our efforts to successfully integrate AW189 aircraft into service for the U.K. SAR contract continue with four of the five basesfifth and final base operational and a fifth expected to be online byon May 1, 2019. As a result of the delays due to a product improvement plan with the aircraft, the acceptance of four AW189 aircraft were pushed to later dates. All of the AW189s have now been accepted and weWe continue to meet our contractual obligations under the U.K. SAR contract through the utilization of other aircraft.

During fiscal year 2018, we reached agreements with OEMs to recover $136.0 million related to ongoing aircraft issues mentioned above, of which $125.0 million was recovered during fiscal year 2018 and $11.0 million was recovered during the Current Period. For further details on the accounting treatment, see Note 1 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report.
Selected Regional Perspectives
We own an approximate 20% voting interest and a 41.9% economic interest in Líder, a provider of helicopter and executive aviation services in Brazil. Brazil represents a significant part of long term helicopter industry demand due to its concentration and size of its offshore oil reserves. However, in the short term, Brazil and, specifically, Petrobras continue to evidence uncertainty as the price of oil and Petrobras’ restructuring efforts have impacted the helicopter industry. The Brazilian government has revisited the regulations on the oil and gas industry and made significant changes to the Brazilian market, including removing the requirement that Petrobras have 30% participation on all exploratory blocks, removing the requirement that Petrobras be the operator of all pre-salt blocks and approving the next round of licensing for new exploration blocks (six years after the last successful round). In addition, the Brazilian government is currently reviewing local content requirements, which has led other operators (including international oil companies) to initiate drilling activities. Petrobras’ new management has implemented a five-year business and management plan focused on divestment, mostly of its non-core businesses. Overall, the long-term Brazilian market outlook has improved with future opportunities for growth although Líder faces significant competition from a number of global and local helicopter service providers.

Líder’s management has significantly decreased their future financial projections as a result of recent tender awards announced by Petrobras. Petrobras represented 64% and 66% of Líder’s operating revenue in calendar years 2017 and 2016, respectively. This significant decline in future forecasted results, coupled with previous declining financial results, triggered our review of our investment in Líder for potential impairment as of March 31, 2018. Based on the estimated fair value of our investment, we recorded an $85.7 million impairment as of March 31, 2018. Our remaining investment in Líder as of September 30,December 31, 2018 is $48.3$52.7 million. Despite this impairment driven by an overall reduction in financial performance, Líder’s management expects to benefit from the recovery in the Brazilian market over the long-term. As of September 30,December 31, 2018, we have no aircraft on lease to Líder. In addition to uncertainty surrounding future financial performance, currency fluctuations continue to make it difficult to predict the earnings from our Líder investment. These currency fluctuations, which primarily do not impact Líder’s cash flow from operations, had a significant negative impact on Líder’s results in recent years, impacting our earnings (losses) from unconsolidated affiliates. Earnings (losses) from unconsolidated affiliates, net on our consolidated statements of operations, is included in calculating adjusted EBITDA, adjusted net income (loss) and adjusted diluted earnings (loss) per share.
We are subject to competition and the political environment in the countries where we operate. In Nigeria, we have seen an increase in competitive pressure and the application of existing local content regulations that could impact our ability to win future work at levels previously anticipated. In order to properly and fully embrace new regulations, we have made a number of key changes to our operating model in Nigeria, while maintaining safety as our number one priority at all times. The objectives of these changes being (a) enhancing the level of continued compliance by each of Bristow Helicopters Nigeria Ltd. (“BHNL”) and Pan African Airlines Nigeria Ltd. (“PAAN”) with local content regulations, (b) the streamlining of our operations in Nigeria, including an ongoing consolidation of operations of BHNL and BGI Aviation Technical Services Nigeria Limited (“BATS”) in order to achieve cost savings and efficiencies in our operations, and (c) each of BHNL and PAAN committing to continue to apply and use all key Bristow Group standards and policies, including without limitation our Target Zero safety program, our Code of Business Integrity and our Operations Manuals. As a result of these changes, our ability to continue to consolidate BHNL and PAAN under the current accounting requirements could change.
The operating results of Airnorth have declined during fiscal year 2019. Continuing declines or negative trends in operating results could lead to an impairment of goodwill, which as of December 31, 2018, was approximately $18.3 million. Management continues to monitor and analyze the results of Airnorth and at this time has concluded that no triggering event has occurred and will reassess as of March 31, 2019.
We conduct business in various foreign countries, and as such, our cash flows and earnings are subject to fluctuations and related risks from changes in foreign currency exchange rates. During the Current Quarter, our primary foreign currency exposure was related to the British pound sterling, the euro, the Australian dollar, the Norwegian kroner and the Nigerian naira and our unconsolidated affiliates foreign currency exposure is primarily related to the Brazilian real. For further details on this exposure and the related impact on our results of operations, see “Item 7A. Quantitative and Qualitative Disclosures about Market Risk” in our fiscal year 2018 Annual Report and Note 1 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report.

These financial measures have not been prepared in accordance with generally accepted accounting principles (“GAAP”) and have not been audited or reviewed by our independent registered public accounting firm. These financial measures are therefore considered non-GAAP financial measures. Adjusted EBITDA is calculated by taking our net income (loss) and adjusting for interest expense, depreciation and amortization, benefit (provision) for income taxes, gain (loss) on disposal of assets and any special items during the reported periods. See further discussion of our use of the adjusted EBITDA metric below. Adjusted net income (loss) and adjusted diluted earnings (loss) per share are each adjusted for gain (loss) on disposal of assets and any special items during the reported periods. As discussed below, management believes these non-GAAP financial measures provide meaningful supplemental information regarding our results of operations. A description of the adjustments to and reconciliations of these non-GAAP financial measures to the most comparable GAAP financial measures is as follows:

(i) 
See information about special items during the Current Quarter and Comparable Quarter under “— Current Quarter Compared to Comparable Quarter” and Current Period and Comparable Period under “— Current Period Compared to Comparable Period” below.
(ii) 
Effective tax rate is calculated by dividing benefit (provision) for income tax by pretax net loss. Adjusted effective tax rate is calculated by dividing adjusted benefit (provision) for income tax by adjusted pretax net loss. Tax provision (benefit) on loss on disposal of assets and tax provision (benefit) on special items is calculated using the statutory rate of the entity recording the loss on disposal of assets or special item.  
(iii) 
These amounts are presented after applying the appropriate tax effect to each item and dividing by the weighted average shares outstanding during the related period to calculate the earnings per share impact.
(iv) 
Adjusted diluted loss per share is calculated using the diluted weighted average number of shares outstanding of 35,768,23235,798,185 and 35,317,93535,368,212 during the Current Quarter and Comparable Quarter, respectively, and of 35,685,38835,712,735 and 35,253,68835,260,746 during the Current Period and Comparable Period, respectively.
Management believes that adjusted EBITDA, adjusted benefit for income taxes, adjusted net loss and adjusted diluted loss per share (collectively, the “Non-GAAP measures”) provide relevant and useful information, which is widely used by analysts, investors and competitors in our industry as well as by our management in assessing both consolidated and regional performance.

Adjusted EBITDA provides us with an understanding of one aspect of earnings before the impact of investing and financing transactions and income taxes. Adjusted EBITDA should not be considered a measure of discretionary cash available to us for investing in the growth of our business.
As prescribed by the SEC, when adjusted EBITDA is discussed in reference to performance on a consolidated basis, the most directly comparable GAAP financial measure to adjusted EBITDA is net income (loss). Management does not analyze interest expense and income taxes on a regional level; therefore, the most directly comparable GAAP financial measure to adjusted EBITDA when performance is discussed on a regional level is operating income (loss).
Adjusted net loss and adjusted diluted loss per share present our consolidated results excluding asset dispositions and special items that do not reflect the ordinary earnings of our operations. Adjusted benefit (provision) for income taxes excludes the tax impact of these items. We believe that these measures are useful supplemental measures because net loss and diluted loss per share include asset disposition effects and special items and benefit (provision) for income taxes include the tax impact of these items, and inclusion of these items does not reflect the ongoing operational earnings of our business.
The Non-GAAP measures are not calculated or presented in accordance with GAAP and other companies in our industry may calculate these measures differently than we do. As a result, these financial measures have limitations as analytical and comparative tools and you should not consider these measures in isolation, or as a substitute for analysis of our results as reported under GAAP. In calculating these financial measures, we make certain adjustments that are based on assumptions and estimates that may prove to be inaccurate. In addition, in evaluating these financial measures, you should be aware that in the future we may incur expenses similar to those eliminated in this presentation. Our presentation of the Non-GAAP measures should not be construed as an inference that our future results will be unaffected by unusual or special items.
Some of the additional limitations of adjusted EBITDA are:
Adjusted EBITDA does not reflect our current or future cash requirements for capital expenditures;
Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs;
Adjusted EBITDA does not reflect the significant interest expense or the cash requirements necessary to service interest or principal payments on our debts; and
Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and adjusted EBITDA does not reflect any cash requirements for such replacements.

We determined that during the three months ended June 30, 2018, we had incorrectly allocated a foreign currency transaction gain and loss between two regions: Europe Caspian and Corporate and other with no impact to consolidated adjusted EBITDA or consolidated other income. This resulted in an overstatement of adjusted EBITDA and other income for Europe Caspian region of $6.9 million and an understatement of adjusted EBITDA and other income for Corporate and other of $6.9 million during the

The year-over-year decrease in operating revenue was primarily driven by a decrease in our oil and gas services driven by decreased flight activity in our AfricaAsia Pacific region, our Canada operations within our Americas region, and our Asia Pacific region in the Current Quarter, with the largest impact coming from our operations in Africa due to a contract that expired on March 31, 2018 partially offset by increased activity with other customers.region. Also, revenue from our fixed wing services in our Europe Caspian and Asia Pacific regionregions declined, partially offset by an increase in operating revenue from our fixed wing services in our Africa and Europe Caspian regions.region. Additionally, revenue decreased by $5.3$7.8 million in the Current Quarter compared to the Comparable Quarter due to changes in foreign currency exchange rates, primarily in our Europe Caspian and Asia Pacific regionregions related to the strengthening of the U.S. dollar versus the British pound sterling and Australian dollar. See further discussion of operating revenue by region under “—Region Operating Results.”
For the Current Quarter, we reported a net loss of $144.2$85.9 million and a diluted loss per share of $4.03$2.40 compared to a net loss of $31.2$8.3 million and a diluted loss per share of $0.88$0.23 for the Comparable Quarter.
The net loss for the Current Quarter was significantly impacted by the following special items:
Loss on impairment of $117.2 million ($101.1 million net of tax), or $2.83 per share, including:
$87.5 million impairment of H225 aircraft and $8.9 million impairment of H225 inventory, and
$20.8 million impairment of Eastern Airways assets including $17.5 million for aircraft and equipment, $3.0 million for intangible assets and $0.3 million for inventory,
Organizational restructuring costs of $2.7$2.4 million ($2.4 million net of tax), or $0.07 per share, included in direct cost and general and administrative expense, resulting from separation programs across our global organization designed to increase efficiency and reduce costs,
Transaction costs of $1.27.2 million ($1.05.7 million net of tax), or $0.030.16 per share, included in general and administrative expense, resulting from the announced agreement to acquire Columbia transaction and related financing transactions, and
A non-cashNon-cash tax expense of $10.3$45.2 million, or $0.29$1.26 per share, including $33.5 million from the valuation allowanceallowances on deferred tax assets.assets and $11.7 million from the Act.
Additionally, we realized a loss on disposal of assets of $1.3$16.0 million ($1.412.5 million net of tax), or $0.04$0.35 per share, during the Current Quarter from the sale or disposalprimarily for contract termination costs of $14.0 million for an aircraft and other equipment.purchase contract that was terminated in December 2018.
In addition to the special items above, theThe year-over-year change in net loss and diluted loss per share was primarily driven by lower revenue in the Current Quarter as discussed above, higher interest expense, foreign currency losseshigher loss on disposal of assets, higher rent expense due to less of a benefit from OEM cost recoveries in the Current Quarter versus foreign currency gainsas discussed below, more of a negative impact from special items in the Current Quarter compared to in the Comparable Quarter, and lower earnings from unconsolidated affiliates,higher tax expense primarily due to valuation allowances on deferred tax assets, partially offset by lower general and administrative expenses, lower losses on disposal of assets, lower rent expense and a more favorable effective tax rate.

expenses.
The Current Quarter results benefited from the impact of $3.4$2.0 million of OEM cost recoveries resulting in a $2.4$1.0 million reduction in rent expense (included in direct cost) and a $1.0 million reduction in direct cost. The Comparable Quarter results benefited from the impact of OEM cost recoveries related to ongoing aircraft issues that resulted in a reduction in rent expense of $13.1 million (included in direct cost). We will recognize an additional $2.0$1.0 million reduction in rent expense and an additional $1.3$0.3 million reduction in direct cost over the remainder of fiscal year 2019 related to these OEM cost recoveries. For further details, see Note 1 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report.
Excluding the special items and the loss on disposal of assets discussed above, adjusted net loss and adjusted diluted loss per share were $28.0$20.3 million and $0.78,$0.57, respectively, for the Current Quarter. These adjusted results compare to adjusted net loss and adjusted diluted loss per share of $11.6$18.5 million and $0.33,$0.52, respectively, for the Comparable Quarter. Adjusted EBITDA decreased to $21.3$23.6 million in the Current Quarter from $32.4$35.0 million in the Comparable Quarter.
The year-over-year change in adjusted EBITDA was primarily driven by the decline in oil and gas revenue and higher rent expense as discussed above, foreign currency losses in the Current Quarter versus foreign currency gains in the Comparable Quarter, lower earnings from unconsolidated affiliates and lower results from our fixed wing services in our Asia Pacific region primarily due to an increase in maintenance expense and decrease in operating revenue.above. These unfavorable changes were partially offset by a decrease in general and administrative expense

primarily from lower salaries and benefits in the Current Quarter and lower rent expense discussed above.Quarter. The year-over-year change in adjusted net loss and adjusted diluted loss per share was impacted by the same items that impacted adjusted EBITDA as well as higher interest expense.expense; however, a more favorable adjusted tax rate in the Current Quarter more than offset these negative changes.
The table below presents the year-over-year impact of changes in foreign currency exchange rates.

The most significant foreign exchange impacts related to a $4.8$3.2 million unfavorable impact from transaction losses in the Current Quarter compared to transaction gains in the Comparable Quarter and a $1.3 millionQuarter. This unfavorable impact of foreign currency exchange rate changes from our investment in Líder in Brazil. Additionally, the Current Quarter includeswas partially offset by a $0.3$2.6 million unfavorablefavorable impact from changes in foreign currency exchange rates primarily driven by the impact of the British pound sterling on the translation of our results in our Europe Caspian region. Additionally, the Current Quarter includes a $0.6 million less unfavorable impact of foreign currency exchange rate changes from our investment in Líder in Brazil.
Direct cost decreased 2.6%3.6%, or $7.5$9.9 million, year-over-year primarily due to an $8.5a $13.3 million decrease in salaries and benefits primarily due to a decrease in the number of employees and a $7.2$2.2 million decrease in various other direct costs, partially offset by a $5.6 million increase in rent expense primarily due to return of leased aircraft andlower OEM cost recoveries, partially offset by a $4.4return of leased aircraft.
Reimbursable expense decreased 5.9%, or $0.9 million, increase in fuel due to increased fuel prices and increased activity, a $3.4 million increase in maintenance expense primarily due to fixed wing servicesa decline in activity in our Asia Pacific and Europe Caspian regions and a $0.4 million increase in various other direct costs.
Reimbursable expense remained mostly flat at $15.2 million for the Current Quarter and $15.4 million for the Comparable Quarter.region.
Depreciation and amortization expense remained mostly flat at $30.5$30.6 million for the Current Quarter compared to $31.4$31.7 million for the Comparable Quarter.

General and administrative expense decreased 20.1%6.1%, or $9.8$2.6 million, in the Current Quarter, as compared to the Comparable Quarter primarily due to a decrease in compensation expense of $6.7$6.2 million primarily resulting from a reduction in short-term and long-term incentive compensation costs of $7.1$4.2 million and a reduction of various other general and administrative expenses of $3.1$2.8 million, including professional fees, information technology, training and travel expenses, as part of continued cost reduction efforts.
Loss on impairment forefforts, partially offset by a $6.4 million increase in professional fees primarily related to the Current Quarter includes $87.5 million for the impairment of H225 aircraft, $8.9 million for the impairment of H225 inventory,Columbia transaction and $20.8 million for the impairment of Eastern Airways assets including $17.5 million for aircraft and equipment, $3.0 million for intangible assets and $0.3 million for inventory.

Loss on disposal of assets decreased $7.2increased $11.4 million to a loss of $1.3$16.0 million for the Current Quarter from a loss of $8.5$4.6 million for the Comparable Quarter. The loss on disposal of assets in the Current Quarter included $14.0 million for contract termination costs for an aircraft purchase contract that was terminated in December 2018, $1.4 million for impairment of assets held for sale and a loss of $1.3$0.7 million from the sale or disposal of aircraft and other equipment. During the Comparable Quarter, the loss on disposal of assets included impairment charges totaling $8.2$1.6 million related to assets held for sale and impairment of the Bristow Academy disposal group and a loss of $0.3$3.0 million from the sale or disposal of aircraft and other equipment.
Earnings (losses) from unconsolidated affiliates, net decreased $2.2$1.2 million to a loss of $0.1$0.8 million for the Current Quarter from earnings of $2.1$2.0 million in the Comparable Quarter. This decrease primarily resulted from a $1.9$1.0 million decrease of earnings from our investment in Líder in Brazil in the Current Quarter primarily due to a decline in activity, andpartially offset by a more$0.6 million less unfavorable impact of foreign currency exchange rates of $1.3 million in the Current Quarter compared to the Comparable Quarter.

Interest expense, net, increased 42.4%42.0%, or $7.9$8.0 million, year-over-year primarily due to an increase in borrowings and an increase in amortization of debt discount.discount, partially offset by an increase in interest income as a result of an increase in cash and cash invested at higher rates.
For further details on income tax expense, see “— Region Operating Results — Taxes” included elsewhere in this Quarterly Report.
As discussed above, our results for the Current Quarter were impacted by special items. During the Comparable Quarter, special items that impacted our results included organizational restructuring costs and tax items. The items noted in the Current Quarter and Comparable Quarter have been identified as special items as they are not considered by management to be part of our ongoing operations when assessing and measuring the operational and financial performance of the organization. The impact of these items on our adjusted EBITDA, adjusted net loss and adjusted diluted loss per share is as follows:

The year-over-year decrease in revenue in the Current Period was primarily driven by a decrease in our oil and gas services driven by declines in our Africa region, Canada operations within our Americas andregion, our Asia Pacific regions, partially offset by increases in oilregion, and gas services in our Europe Caspian region. See further discussion of operating revenue by region under “— Region Operating Results.” These decreases were partially offset by an increase in U.K. SAR services revenue due to additional bases coming online in fiscal years 2017 andyear 2018, and an increasethe full benefit of which was received in operating revenue from our fixed wing services in our Europe Caspian and Africa regions.the Current Period. The U.K. SAR services revenue includes the one-time benefit of $7.6 million in OEM cost recoveries recognized in the Current Period. Additionally, revenue increaseddecreased by $5.2$2.7 million in the Current Period compared to the Comparable Period due to changes in foreign exchange rates, primarily in our Asia Pacific region related to the weakening of the Australian dollar versus the U.S. dollar, partially offset by our Europe Caspian region related to the strengthening of the British pound sterling versus the U.S. dollar, partially offsetdollar. See further discussion of operating revenue by the weakening of the Australian dollar versus the U.S. dollar.region under “— Region Operating Results.”
For the Current Period, we reported a net loss of $176.3$262.2 million and a diluted loss per share of $4.94$7.34 compared to a net loss of $86.5$94.8 million and a diluted loss per share of $2.45$2.69 for the Comparable Period.
The net loss for the Current Period was significantly impacted by the following special items:
Loss on impairment of $117.2 million ($101.1 million net of tax), or $2.83 per share, including:
$87.5 million impairment of H225 aircraft and $8.9 million impairment of H225 inventory, and
$20.8 million impairment of Eastern Airways assets including $17.5 million for aircraft and equipment, $3.0 million for intangible assets and $0.3 million for inventory,
Organizational restructuring costs of $4.4$6.9 million ($4.16.5 million net of tax), or $0.11$0.18 per share, included in direct cost and general and administrative expense, resulting from separation programs across our global organization designed to increase efficiency and reduce costs,
Transaction costs of $1.2$8.4 million ($1.06.6 million net of tax), or $0.03$0.19 per share, included in general and administrative expense, resulting from the announced agreement to acquire Columbia transaction and related financing transactions, and
A non-cashNon-cash tax expense of $10.3$55.5 million, or $0.29$1.55 per share, including $43.8 million from the valuation allowanceallowances on deferred tax assets.assets and $11.6 million from the Act.
In addition to the special items above, theThe year-over-year change in net loss and diluted loss per share was primarily driven by highera significant increase in the negative impact of special items mostly from asset impairments, lower revenue from U.K. SARas discussed above, a decreasehigher interest expense, foreign currency impact, higher loss on disposal of assets and lower earnings from unconsolidated affiliates in general and administrative expense, lower rent expense and a more favorable effective tax rate.the Current Period. These favorableunfavorable changes were partially offset by declinea decrease in the oilsalaries and gas services revenue, higher interestbenefits, rent expense and foreign currency losses in the Current Period compared to foreign currency gains in the Comparable Period.general and administrative expense.
The Current Period results benefited from the impact of $15.6$17.6 million of OEM cost recoveries realized in the Current Period resulting in a one-time benefit of $7.6 million in U.K. SAR operating revenue, a $5.9$6.9 million reduction in rent expense (included in direct cost) and a $2.1$3.1 million reduction in direct cost. The Comparable Period benefited from a reduction in rent expense of $13.1 million included in direct costs related to OEM cost recoveries. For further details, see Note 1 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report.
Excluding the special items described above and the loss on disposal of assets, adjusted net loss and adjusted diluted loss per share were $57.1$77.4 million and $1.60,$2.17, respectively, for the Current Period. These adjusted results compare to adjusted net loss and adjusted diluted loss per share of $40.7$59.2 million and $1.16,$1.68, respectively, for the Comparable Period. Additionally, adjusted EBITDA decreased to $48.1$71.7 million in the Current Period from $47.6$82.5 million in the Comparable Period.

The year-over-year change in adjusted EBITDA was primarily driven by the decline in oil and gas revenue discussed above, foreign currency impact and lower resultsearnings from our fixed wing servicesunconsolidated affiliates in our Asia Pacific region primarily due to an increase in maintenance expense and decrease in operating revenue.the Current Period. These unfavorable changes were mostly offset by a decrease in general and administrative expense primarily from lower salaries and benefits in the Current Period and lower rent expense discussed above.expense. The year-over-year change in adjusted net loss and adjusted diluted loss per share was impacted by the same items that impacted adjusted EBITDA andas well as higher interest expense.expense; however, a more favorable adjusted tax rate in the Current Period more than offset these negative changes.
The table below presents the year-over-year impact of changes in foreign currency exchange rates.

The most significant foreign exchange impact related to a $6.2$9.3 million unfavorable impact from transaction losses in the Current Period compared to transaction gains in the Comparable Period. Additionally, results for the Current Period were impacted by a $2.7$2.2 million increase in unfavorable foreign currency exchange rate impact from our investment in Líder in Brazil. Partially offsetting these unfavorable impacts was a $4.9$7.5 million favorable impact from changes in foreign currency exchange rates in the Current Period primarily driven by the impact of the appreciating British pound sterling on the translation of our results in our Europe Caspian region, partially offset by the impact of the depreciating Australian dollar on the translation of our results in our Asia Pacific region.
Direct costs decreased 2.3%2.7%, or $13.1$22.9 million, year-over-year primarily due to lower headcount across all regions due to the benefit of organizational restructuring efforts reflected in a $15.6$28.9 million decrease in salaries and benefits and a $15.7$10.1 million decrease in rent expense primarily due to return of leased aircraft, and OEM cost recoveries, partially offset by a $9.7$12.8 million increase in fuel primarily due to an increase in fuel prices a $6.4 million increase in maintenance costs primarily due to fixed wing services in our Europe Caspian and Asia Pacific regions and a $2.1$3.3 million increase in various other direct costs.
Reimbursable expense increased 12.5%6.1%, or $3.5$2.6 million, primarily due to new contracts in our Asia Pacific and Africa regions.region.
Depreciation and amortization expense remained mostly flat at $61.4$92.0 million for the Current Period compared to $62.4$94.1 million for the Comparable Period.
General and administrative expense decreased 17.2%13.7%, or $16.4$19.0 million, in the Current Period, as compared to the Comparable Period primarily due to a $10.5$16.6 million decrease in compensation expense (primarily due to a decrease in severance costs of $6.8$6.6 million, a $8.8 million decrease in short-term and $3.7long-term incentive compensation costs and $1.2 million lower salaries and benefits due to a reduction in headcount across all regions), and a $4.3$7.2 million decrease in information technology, travel, training and various other expenses, andpartially offset by a $1.6$4.8 million decreaseincrease in professional fees as a result of continued cost reduction efforts.primarily related to the Columbia transaction and related financing transactions.
Loss on impairment for the Current Period includes $87.5 million for the impairment of H225 aircraft, $8.9 million for the impairment of H225 inventory, and $20.8 million for the impairment of Eastern Airways assets including(including $17.5 million for aircraft and equipment, $3.0 million for intangible assets and $0.3 million for inventory.inventory). For further details, Note 1 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report. Loss on impairment for the Comparable Period includes a $1.2 million impairment charge on inventory used on our training fleet.

Loss on disposal of assets decreased $4.9increased $6.6 million, to a loss of $3.0$19.0 million for the Current Period from a loss of $7.8$12.4 million for the Comparable Period. The loss on disposal of assets in the Current Period included $14.0 million of contract termination costs for an aircraft purchase contract that was terminated in December 2018, $1.4 million for impairment of assets held for sale and a loss of $3.0$3.7 million from the sale or disposal of aircraft and other equipment. During the Comparable Period, the loss on disposal of assets included impairment charges totaling $9.7$11.3 million related to assets held for sale (including a $6.5$7.2 million impairment and loss on disposal related to the Bristow Academy disposal group), partially offset byand a gainloss of $1.9$1.1 million related to the sale of aircraft and other equipment.
Earnings (losses) from unconsolidated affiliates, net decreased $4.5$5.7 million to a loss of $3.1$2.3 million for the Current Period from earnings of $1.4$3.4 million in the Comparable Period. The decrease in earnings (losses) from unconsolidated affiliates, net primarily resulted from a decrease in earnings from our investment in Líder in Brazil to a loss of $1.8$0.1 million in the Current Period from $3.0earnings of $5.7 million in earnings in the Comparable Period primarily due to a $2.7decline in activity and a $2.2 million more unfavorable impact of foreign currency exchange rates and a decrease in activity.rates.
Interest expense, net, increased 54.9%50.3%, or $19.0$27.0 million, year-over-year primarily due to an increase in borrowings and an increase in amortization of debt discount.discount, partially offset by an increase in interest income as a result of an increase in cash and cash invested at higher rates.

As discussed above, our results for the Current Period were impacted by special items. During the Comparable Period, special items that impacted our results included organizational restructuring costs, inventoryloss on impairment and tax items. The items noted in the Current Period and Comparable Period have been identified as special items as they are not considered by management to be part of our ongoing operations when assessing and measuring the operational and financial performance of the organization.

The Europe Caspian region comprises all of our operations and affiliates in Europe, including oil and gas operations in the U.K. and Norway, Eastern Airways fixed wing operations and public sector SAR operations in the U.K. and our operations in Turkmenistan.
Current Quarter Compared to Comparable Quarter
Operating revenue for our Europe Caspian region was mostly unchangeddecreased in the Current Quarter compared to the Comparable Quarter withprimarily due to a $1.8decrease of $6.7 million in U.K. oil and gas revenue due to a decrease in activity and unfavorable year-over-year impactchanges in foreign currency exchange rates, a decrease of $5.0 million in fixed wing revenue from Eastern Airways due to a decrease in activity and unfavorable changes in foreign currency exchange rates and a decrease in U.K. SAR revenue of $1.5$1.3 million primarily due to unfavorable changes in foreign currency exchange rates. Partially offsetting these decreases is an increase in Norway operating revenue of $3.9 million driven by less short-term activity being mostly offset by an increase of $0.9in activity. Additionally, revenue decreased by $5.2 million in fixed wing revenue from Eastern Airways and an increase of $0.9 million for U.K. SAR revenue.the Current Quarter compared to the Comparable Quarter due to unfavorable changes in foreign currency exchange rates. Eastern Airways contributed $31.4$24.4 million and $30.5$29.5 million in operating revenue for the Current Quarter and Comparable Quarter, respectively.
A substantial portion of our operations in the Europe Caspian region are contracted in the British pound sterling, which depreciated against the U.S. dollar in the Current Quarter. We recorded foreign exchange losses of $1.0$2.1 million in the Current Quarter and foreign exchange gains of $1.9$1.3 million in the Comparable Quarter from the revaluation of assets and liabilities on pound sterling functional currency entities as of September 30,December 31, 2018 and 2017, respectively, which is recorded in other income (expense), net and included in adjusted EBITDA. The Current Quarter benefited from a $0.7$1.4 million impact from foreign currency hedging, which partially offset the negative impact from exchange rate changes. A further weakening or strengthening of the British pound sterling could result in additional foreign exchange volatility in future quarters.
During the Current Quarter, we recorded $20.8 million for impairment of Eastern Airways assets including $17.5 million for aircraft and equipment, $3.0 million for intangible assets and $0.3 million for inventory. For further details, Note 1 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report. The impairments are excluded from adjusted EBITDA and adjusted EBITDA margin.
The Current Quarter results benefited from OEM cost recoveries in prior periods that resulted in a $1.6 million reduction in rent expense and a $1.0$1.2 million reduction in direct cost. The Comparable Quarter benefited from OEM cost recoveries that resulted in a $7.1 million reduction in rent expenses (included in direct cost). We will recognize an additional $0.5 million reduction in rent expense and an additional $1.3 million reduction in direct cost over the remainder of fiscal year 2019 related to these OEM cost recoveries in our Europe Caspian region results. These items are included in operating income and adjusted EBITDA in the Current Quarter and Comparable Quarter. For further details, see Note 1 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report.
The decrease in operating income and operating margin from the Comparable Quarter was primarily due to lower revenue discussed above and lower OEM cost recoveries of $5.9 million, partially offset by lower salaries and benefits of $5.3 million. In addition to the $20.8 million of impairments of Eastern Airways assets mentioned above. Adjusteditems impacting operating income and operating margin, adjusted EBITDA and adjusted EBITDA margin decreased primarily due to the foreign exchange losses from revaluation of assets and liabilities included in other income (expense), net in the Current Quarter compared to gains recorded in the Comparable Quarter. As discussed above, other income (expense) is included in adjusted EBITDA, but not in operating income. Eastern Airways contributed a negative $0.7$5.4 million and positive $0.2negative $4.1 million in adjusted EBITDA for the Current Quarter and Comparable Quarter, respectively.

Current Period Compared to Comparable Period
The increase in operating revenue in the Current Period compared to the Comparable Period primarily resulted from an increase of $14.6$13.3 million for U.K. SAR revenue including a one-time benefit of OEM cost recovery of $7.6 million, an increase of $7.9$3.0 million in fixed wing revenue from Eastern Airways and an increase of $2.4$6.3 million in Norway operating revenue resulting from an increase in activity, partially offset by a $6.3 million decrease in U.K. oil and gas activity due to a decline in activity. Additionally, revenue increased by $9.0$3.8 million in the Current Period compared to the Comparable Period due to favorable changes in foreign currency exchange rates. Eastern Airways contributed $66.3$90.8 million and $58.4$87.8 million in operating revenue for the Current Period and Comparable Period, respectively.
The Current Period results benefited from OEM cost recoveries realized in the Current Period related to ongoing aircraft issues that resulted in a one-time benefit of $7.6 million in U.K. SAR operating revenue, a $4.3$4.5 million reduction in rent expense and a $2.1$3.1 million reduction in direct cost. The Comparable Period benefited from OEM cost recoveries that resulted in a $7.1 million reduction in rent expense (included in direct cost).
A substantial portion of our operations in the Europe Caspian region are contracted in the British pound sterling, which depreciated against the U.S. dollar in the Current Period. We recorded foreign exchange losses of $6.3$8.4 million in the Current Period and foreign exchange gains of $1.4$2.8 million in the Comparable Period from the revaluation of assets and liabilities on British pound sterling functional currency entities as of September 30,December 31, 2018 and 2017, respectively, which is recorded in other income (expense), net and included in adjusted EBITDA. Net of the translation and revaluation impacts, adjusted EBITDA was negatively impacted by $7.9$9.4 million and positively impacted by $1.5$4.8 million resulting from the change in exchange rates during the Current Period and Comparable Period, respectively. The Current Period results benefited from a $0.8$2.2 million impact from foreign currency hedging, which partially offset the negative impact from exchange rate changes. A further weakening or strengthening of the British pound sterling could result in additional foreign exchange volatility in future periods.
During the Current Period, we recorded $20.8 million for impairment of Eastern Airways assets including $17.5 million for aircraft and equipment, $3.0 million for intangible assets and $0.3 million for inventory. For further details, Note 1 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report. The impairments are excluded from adjusted EBITDA and adjusted EBITDA margin.
The decrease in operating income and operating margin from the Comparable QuarterPeriod was primarily due to the $20.8 million of impairments of Eastern Airways assets mentioned above, and increased maintenance expense year-over-year due to the increase in activity, partially offset by the increase in operating revenue discussed above and the larger benefit to rent expensefrom OEM cost recoveries in the Current Period related to OEM cost recoveries.Period. Adjusted EBITDA and adjusted EBITDA margin increaseddecreased in the Current Period primarily due to the increase in operating revenue and the benefit to rent expense in the Current Period related to OEM cost recoveries. These benefits were partially offset by increased maintenance expense year-over-year due to the increase in activity and the unfavorable year-over-year impacts from changes in foreign currency exchange rates.rates, partially offset by the increase in operating revenue and larger benefit from OEM cost recoveries in the Current Period. Eastern Airways contributed a negative $0.9$6.3 million and positive $0.4a negative $3.7 million in adjusted EBITDA for the Current Period and Comparable Period, respectively.

Current Quarter Compared to Comparable Quarter
Operating revenue for Africa decreased in the Current Quarter due to an overall decrease in activity compared to the Comparable Quarter. Activity declined with certain customers and certain contracts ended, including a contract that expired on March 31, 2018, reducing revenue by $17.3$15.4 million, which was partially offset by an increase in activity with other customers increasing revenue by $4.9$7.4 million and an increase in fixed wing services revenue of $1.2$1.4 million. Fixed wing services in Africa generated $2.8$3.4 million and $1.6$2.0 million in operating revenue for the Current Quarter and Comparable Quarter, respectively.
Operating income, operating margin, adjusted EBITDA and adjusted EBITDA margin decreased as a result of the decrease in operating revenue in the Current Quarter, which was partially offset by a decrease in direct cost and general and administrative expenses. Additionally, during the Comparable Quarter, we recorded $0.2$0.5 million in severance expense related to organizational restructuring efforts, which is excluded from adjusted EBITDA and adjusted EBITDA margin.
As previously discussed,With the conclusion of the recent elections, we have seen recent changesanticipate a measure of stability in the Africa region as a result of increased competition entering the Nigerian market. Additionally, the uncertainty of the political environment could have an impact onthrough the Nigerian market. In particular, nationwide elections in early 2019 couldmedium term and increased drilling activities; however, we are also seeing increased pressure to benchmark and standardize commercial rates across multiple contracts, which may affect the levelprofitability of activitycontracts in the months leading to the elections. Market uncertainty related to the oil and gas downturn has continued in this region putting smaller customers under increasing pressure as their activity declined, which reduced our activity levels and overall pricing.Nigeria.

The Americas region comprises all our operations and affiliates in North America and South America, including Brazil, Canada, Guyana, Trinidad and the U.S. Gulf of Mexico.
Current Quarter Compared to Comparable Quarter
Operating revenue decreased in the Current Quarter primarily due to a decrease in operating revenue of $3.3$2.8 million in Canada and $0.6 million in the U.S. Gulf of Mexico resulting from lower activity, a decrease in intra-region operating revenue of $1.1 million primarily resulting from a decrease in activity in Africa and a decrease in operating revenue of $0.9 million for lease return billings in Brazil in the Comparable Quarter, partially offset by an increase in activity with our U.S. Gulf of MexicoTrinidad oil and gas customers, which increased operating revenue by $2.9$1.2 million.

Earnings (losses) from unconsolidated affiliates, net decreased $2.1$1.3 million primarily due to a reduction in earnings from our investment in Líder in Brazil resulting from a decline in activity, and anpartially offset by a less unfavorable change in foreign currency exchange rates. Changes in foreign currency exchange rates decreased our earnings from our investment in Líder by $1.0 $0.2

million and $0.8 million, respectively, in the Current Quarter and increased our earnings from our investment in Líder by $0.3 million in the Comparable Quarter. See further discussion about our investment in Líder and the Brazil market in “— Executive Overview — Market Outlook” included elsewhere in this Quarterly Report.
The decreases in operatingOperating income, operating margin, adjusted EBITDA and adjusted EBITDA margin were driven byall mostly flat as the decreases in earnings from unconsolidated affiliates and operating revenue discussed above were mostly offset by a $2.0 million decrease in salaries and increasebenefits due to lower headcount and a $0.7 million decrease in rent expense. Additionally, we recorded severance expense, related to organizational restructuring efforts, of $0.1 million and $0.2$0.1 million for the Current Quarter and Comparable Quarter, respectively, which is excluded from adjusted EBITDA and adjusted EBITDA margin.

Operating loss increased and operating margin, adjusted EBITDA and adjusted EBITDA margin decreased in the Current Quarter primarily due to a decrease in operating revenue discussed aboveabove. Additionally, rent expense increased $5.1 million primarily due to a decrease in OEM credits. We realized OEM credits of $0.8 million and a $3.4$6.0 million, increaserespectively, in maintenance expense at Airnorth,the Current Quarter and Comparable Quarter. These unfavorable changes were partially offset by a $4.3$5.1 million decrease in salaries and benefits due to headcount reductions, a $2.3 million reduction

to rent expense related to the return of leased aircraft and OEM cost recoveries, and a $1.4 million decrease in general and administrative expenses.reductions. Additionally, changes in foreign exchange rates negatively impacted adjusted EBITDA results by $2.3$2.1 million compared to the Comparable Quarter primarily due to foreign exchange rate losses of $1.1$2.3 million and $0.3 million,

respectively, for the Current Quarter compared to foreign exchange rate gains of $0.8 million for theand Comparable Quarter. Airnorth contributed a negative $1.9$1.2 million and positive $5.6$2.2 million in adjusted EBITDA for the Current Quarter and Comparable Quarter, respectively.

Other income (expense), net for the Current and Comparable Quarters and Current and Comparable Periods were most significantly impacted by foreign currency gains (losses). The foreign currency gains (losses) within other income (expense), net are reflected within the results (below operating income) of the regions shown in the table above.
Transaction gains and losses represent the revaluation of monetary assets and liabilities from the currency that will ultimately be settled into the functional currency of the legal entity holding the asset or liability. The most significant items revalued are denominated in U.S. dollars on entities with British pound sterling, Australian dollar and Nigerian naira functional currencies and denominated in British pound sterling on entities with U.S. dollar functional currencies with transaction gains or losses primarily resulting from the strengthening or weakening of the U.S. dollar versus those other currencies.

We estimate the full-year effective tax rate from continuing operations and apply this rate to our year-to-date income from continuing operations. In addition, we separately calculate the tax impact of unusual or infrequent items, if any. The tax impact of such unusual or infrequent items is treated discretely in the quarter in which they occur.
The relationship between our provision for or benefit from income taxes and our pre-tax book income can vary significantly from period to period considering, among other factors, (a) the overall level of pre-tax book income, (b) changes in the blend of income that is taxed based on gross revenues or at high effective tax rates versus pre-tax book income or at low effective tax rates

and (c) our geographical blend of pre-tax book income. Consequently, our income tax expense or benefit does not change proportionally with our pre-tax book income or loss. Significant decreases in our pre-tax book income typically result in higher effective tax rates, while significant increases in pre-tax book income can lead to lower effective tax rates, subject to the other factors impacting income tax expense noted above. The change in our effective tax rate excluding discrete items for the Current Quarter compared to the Comparable Quarter primarily related to changes in the blend of earnings taxed in relatively high taxed jurisdictions versus low taxed jurisdictions.
Valuation allowances represent the reduction of our deferred tax assets. We evaluate our deferred tax assets quarterly which requires significant management judgment to determine the recoverability of these deferred tax assets by assessing whether it is more likely than not that some or all of the deferred tax assetassets will be realized before expiration. After considering all available positive and negative evidence using a “more likely than not” standard, we believe it is appropriate to value against deferred tax assets related to certain foreign net operating losses and certain foreign tax credits. As a result, we recorded a valuation allowance of $30.4 million against foreign tax credits for the Current Quarter and $3.1 million and $2.1 million against net operating losses in certain foreign jurisdictions for the Current Quarter and Comparable Quarter, respectively. During the Current Period and Comparable Period, we recorded a valuation allowance of $9.3$30.4 million and $0.2$7.6 million, respectively, against foreign tax credits and $13.4 million and $5.8 million, respectively, against net operating losses in certain foreign jurisdictions. During the Current Period and Comparable Period, we increased our valuation allowance by $10.3 million and $3.7 million, respectively, against net operating losses in certain foreign jurisdictions. Additionally, during the Comparable Period, we increased our valuation allowance by $7.6 million against foreign tax credits.
On December 22, 2017, the president of the United States signed into law the Act. The Act includes numerous changes in existing U.S. tax law, including a permanent reduction in the U.S. federal corporate income tax rate from 35% to 21%. The rate reduction takes effect on January 1, 2018. Further, the Act provides for a one-time “deemed repatriation” of accumulated foreign earnings of certain foreign corporations. Under U.S. generally accepted accounting principles, our net deferred tax liabilities are required to be revalued during the period in which the new tax legislation is enacted. We have made reasonable estimates forcompleted our analysis of the change in the U.S. federal corporate income tax rate and one-time “deemed repatriation” of accumulated foreign earnings. For fiscal year 2018, our provision for income tax included provisional amounts for the revaluation of U.S. net deferred tax liabilities, the impactimplications of the “deemed repatriation” of foreign earnings. TheAct during the Current Quarter and recorded adjustments accordingly to previously reported provisional amounts associated with the one-time “deemed repatriation” and the re-measurement of deferred tax assets and liabilities due to the reduction in the corporate income tax rate will be adjusted over time as more guidance becomes available.amounts.
Certain provisions under the Act became applicable to us on April 1, 2018 and our income tax provision for the Current Period includes the tax implications of these provisions. These provisions include Global Intangible Low-Taxed Income (“GILTI”), Base Erosion and Anti-Avoidance Tax (“BEAT”), Foreign Derived Intangible Income (“FDII”), and certain limitations on the deduction of interest expense and utilization of net operating losses.
Liquidity and Capital Resources
Cash Flows
Operating Activities
Net cash flows used in operating activities were $26.968.9 million and $35.3$9.3 million during the Current Period and Comparable Period, respectively. The decreaseincrease in net cash flows used in operating activities in the Current Period primarily resulted from a decreaseOEM cost recoveries in the Comparable Period that did not recur in the Current Period and an increase in cash flow used in working capital changes. Changes in non-cash working capital used $13.137.9 million and $27.018.2 million in cash flows from operating activities for the Current Period and Comparable Period, respectively. Cash flows from operations for the Comparable Period includes $30.5 million related to OEM cost recoveries of which $20.1 million is included in cash flows from operations before working capital changes and $10.4 million is included in working capital changes.

Investing Activities
Cash flows used in investing activities were $8.824.6 million during the Current Period and cash flows provided by investing activities were $17.9106.6 million during the Comparable Period. Cash was used primarily for capital expenditures as follows:

Future Cash Requirements
Contractual Obligations, Commercial Commitments and Off Balance Sheet Arrangements
We have various contractual obligations that are recorded as liabilities on our condensed consolidated balance sheet. Other items, such as certain purchase commitments, interest payments and other executory contracts are not recognized as liabilities on our condensed consolidated balance sheet but are included in the table below. For example, we are contractually committed to make certain minimum lease payments for the use of property and equipment under operating lease agreements.

The following table summarizes our significant contractual obligations and other commercial commitments on an undiscounted basis as of September 30,December 31, 2018 and the future periods in which such obligations are expected to be settled in cash. In addition, the table reflects the timing of principal and interest payments on outstanding borrowings as of September 30,December 31, 2018 based on the contractual terms and has not been amended to reclassifyclassify substantially all of our long-term debt as current for any possible accelerations as discussed in Note 4 in the Explanatory Note“Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report.Report and does not reflect the impact of Chapter 11 Cases and the resulting acceleration of substantially all of our long-term debt. Additional details regarding these obligations are provided in Notes 4, 5, 7 and 9 in the “Notes to Consolidated Financial Statements” included in the fiscal year 2018 Annual Report and in Notes 4, 5, 76, 8 and 910 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report.

On May 1, 2019, we entered into an amendment to our agreement with Airbus Helicopters for the purchase of 22 H175 helicopters which includes five aircraft that can be cancelled by us prior to the delivery dates. Pursuant to the amendment, the parties mutually agreed to postpone the delivery dates for such helicopters for 18 months from the previous schedule with the first three helicopters now scheduled for delivery in the second half of fiscal year 2022. The postponement in deliveries resulted in various amendments to the payment terms under the purchase agreement including the deferral of approximately $110.0 million in capital expenditures scheduled for fiscal years 2019 to 2023 into fiscal years 2024 and beyond. In connection with this amendment, the overall purchase price of these helicopters has been increased by $18.4 million to account for inflation. The impact of this amendment is not included in the table above.
(8) 
Other purchase obligations primarily represent unfilled purchase orders for aircraft parts and non-cancelable power-by-the-hour maintenance commitments. For further details on the non-cancelable power-by-the-hour maintenance commitments, see Note 1 in the “Notes to Consolidated Financial Statements” included in the fiscal year 2018 Annual Report.
Subject to certain exceptions, under the Bankruptcy Code, we may assume, assign or reject certain executory contracts and unexpired leases, subject to the approval of the Bankruptcy Court and satisfaction of certain other conditions. Generally, the rejection of an executory contract or unexpired lease is treated as a pre-petition breach of such executory contract or unexpired lease and, subject to certain exceptions, relieves us of performing our future obligations under such executory contract or unexpired lease but entitles the contract counterparty or lessor to a pre-petition general unsecured claim for damages caused by such deemed

breach. Generally, the assumption of an executory contract or unexpired lease will require us to cure existing monetary and non-monetary defaults under such executory contract or unexpired lease and provide adequate assurance of future performance. Accordingly, any description of an executory contract or unexpired lease in this Quarterly Report, including where applicable a quantification of the obligations under any such executory contract or unexpired lease, is qualified by any overriding assumption or rejection rights we have under the Bankruptcy Code. Further, nothing herein is or shall be deemed to be an admission with respect to any claim amounts or calculations arising from the rejection of any executory contract or unexpired lease and we expressly reserve all our rights with respect thereto.
As of the date of this Quarterly Report, we have filed motions to reject certain leases and we continue to evaluate if we will seek to assume or reject additional leases or purchase contracts in connection with the Chapter 11 Cases. Any decision to assume or reject any leases or purchase contracts will be made by our management in consideration of then-existing economic, market and legal conditions and other relevant considerations, subject to the Bankruptcy Court and potentially other approvals.
Capital Commitments and Other Uses of Cash
We have commitments and options to make capital expenditures over the next seven fiscal years to purchase additional aircraft, including aircraft associated with the commitments reflected in the table above. Although a similar number of our existing aircraft may be sold during the same period, the additional aircraft on order are expected to provide incremental fleet capacity in terms of revenue, operating margin and adjusted EBITDA margin. See Note 78 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report for a detail of the number of aircraft under commitments and options expected to be delivered in the current and subsequent fiscal years by aircraft size along with the related expenditures.
As discussed under “— Executive Overview — Our Strategy”, cash may also be used in future periods to repurchase or otherwise retire debt or for any acquisition opportunities we believe are aligned with our long-term strategy.
Financial Condition and Sources of Liquidity
The significant factors that affect our overall liquidity include cash from or used to fund operations, capital expenditure commitments, debt service, pension funding, adequacy of bank lines of credit and our ability to attract capital on satisfactory terms.
As of September 30,December 31, 2018, approximately 23%34% our cash balances are held outside the U.S. and are generally used to meet the liquidity needs of our non-U.S. operations. Most of our cash held outside the U.S. could be repatriated to the U.S., and any such repatriation could be subject to additional foreign taxes. As a result of the Act, we have provided for U.S. federal income taxes on undistributed foreign earnings. If cash held by non-U.S. operations is required for funding operations in the U.S., we may make a provision for additional tax in connection with repatriating this cash, which is not expected to have a significant impact on our results of operations.
The Company’s liquidity outlook has recently changed since the date of the Company’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2018, originally filed with the SEC on November 9, 2018 (the “Original Filing”), resulting in substantial doubt about the Company’s ability to continue as a going concern.
As discussed in the Explanatory Note included elsewhere in this Quarterly Report, on On May 11, 2019, Bristow Group Inc. and its subsidiaries BHNA Holdings Inc., Bristow Alaska Inc., Bristow Helicopters Inc., Bristow U.S. Leasing LLC, Bristow U.S. LLC, BriLog Leasing Ltd. and Bristow Equipment Leasing Ltd. (together, the “Debtors”)Debtors filed voluntary petitions (the “ChapterChapter 11 Cases”)Cases in the United States Bankruptcy Court for the Southern District of Texas, Houston Division (the “Bankruptcy Court”) seeking relief under Chapter 11 of Title 11 of the United States Code (the “Bankruptcy Code”).Bankruptcy Code. The Debtors’ Chapter 11 Cases are jointly administered under the caption In re: Bristow Group Inc., et al., Main Case No. 19-32713. The Debtors continue to operate their businesses and manage their properties as “debtors-in-possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court. EachIn addition, each of the commencement of the Chapter 11 Cases and the delivery of the Amended 10-K with a going concern qualification or explanation constituted an event of default under certain of our secured equipment financings, giving those secured equipment lenders the right to accelerate repayment of the applicable debt, subject to Chapter 11 protections, and triggering cross-default and/or cross-acceleration provisions in substantially all of our other debt instruments should that right to accelerate repayment be exercised. As such, substantially all of our debt is in default and accelerated, but subject to stay under the Bankruptcy Code.
As a result of the facts and circumstances discussed above, the Company concluded thathas classified substantially all debt balances of approximately $1.4 billion should be reclassified from long-term to short-term as of MarchDecember 31, 2018 within the Amended 10-Kas short-term borrowings and ascurrent maturities of September 30, 2018 within this Amendment No. 1 to the Original Filinglong-term debt on our condensed consolidated balance sheet.
On May 10, 2019, we entered into the RSA with (i) Supporting Secured Noteholders and (ii) the guarantors of the 8.75% Senior Secured Notes, to support the Restructuring on the terms set forth in the Restructuring Term Sheet. The RSA contemplates the filing of the Chapter 11 Cases to implement the Restructuring pursuant to the Plan and the various related transactions set forth in or contemplated by the Restructuring Term Sheet, the DIP Term Sheet and the other restructuring documents attached to the RSA.
The RSA contains certain covenants on the part of each of the Company and the Supporting Secured Noteholders, including limitations on the Supporting Secured Noteholders’ ability to pursue alternative transactions, commitments by the Supporting Secured Noteholders to vote in favor of the Plan and commitments of the Company and the Supporting Secured Noteholders to

negotiate in good faith to finalize the documents and agreements governing the Plan. The RSA also provides for certain conditions to the obligations of the parties and for termination upon the occurrence of certain events, including without limitation, the failure to achieve certain milestones and certain breaches by the parties under the RSA.
On May 10, 2019, we entered into the Term Loan Agreement for the $75 million 2019 Term Loan. Immediately upon entering into the Term Loan Agreement, and prior to the Petition Date, the Company and BHC III borrowed the full amount thereunder, the net proceeds of which may be used only in compliance with a cash flow forecast required pursuant to the terms of the Term Loan Agreement, which the Company expects will be used for general corporate purposes, including to fund the working capital and liquidity requirements of the Company during the pendency of the Chapter 11 Cases. For further details, see “— Recent Events — Term Loan Agreement” above.
On February 11, 2019, we announced that Bristow and Columbia have mutually agreed to terminate our agreement to acquire Columbia. In connection with the termination, we paid $20 million to Columbia in February 2019. Bristow, Columbia and Columbia’s shareholders have agreed to release each other from all claims in connection with the purchase agreement and the related transactions. For further details, see Note 2 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report.
Critical Accounting Policies and Estimates
See Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Policies and Estimates” in the fiscal year 2018 Annual Report for a discussion of our critical accounting policies. There have been no material changes to our critical accounting policies and estimates provided in the fiscal year 2018 Annual Report.

Recent Accounting Pronouncements
See Note 1 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report for a discussion of recent accounting pronouncements.
Item 3.    Quantitative and Qualitative Disclosures about Market Risk.
We are subject to certain market risks arising from the use of financial instruments in the ordinary course of business. This risk arises primarily as a result of potential changes in the fair market value of financial instruments that would result from adverse fluctuations in foreign currency exchange rates, credit risk, and interest rates as discussed in “Item 7A. Quantitative and Qualitative Disclosures About Market Risk” in the fiscal year 2018 Annual Report and Note 1 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report.

Item 4.    Controls and Procedures.
EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURESMaterial Weakness Previously Disclosed
SubsequentAs disclosed in an amendment (the “Amendment”) to our Annual Report on Form 10-K for the evaluation madeyear ended March 31, 2018 (the “2018 Form 10-K” or “Amended 10-K”), we identified a material weakness in connectionour internal controls over financial reporting for monitoring of compliance with the Original Filingnon-financial covenants within certain secured financing and lease agreements in connection with the evaluation and procedures carried out in connection with ourthis Quarterly Report on Form 10-Q for the quarterly periodquarter ended December 31, 2018, our management, including L. Don Miller, our current Chief Executive Officer (“CEO”), and Brian J. Allman, our current Chief Financial Officer (“CFO”), re-evaluated the effectiveness of the design and operation of our disclosure controls and procedures.2018.  As a result of the material weakness in internal control over financial reporting described below, our CEOcommencing Chapter 11 Cases and CFO have concluded that our disclosure controls and procedures were not effective as of March 31, 2018.
As discussed in the Explanatory Note included elsewhere in this Quarterly Report, as a result of updating our going concern assessment and filingthe delivery of the Amended 10-K with such a going concern qualification or explanation, an event of default will exist under certain secured equipment financings and trigger cross-default and/orand cross-acceleration provisions in substantially all of our debt instruments. As a result, we reclassified $1.4 billion as of September 30 and March 31, 2018 from long-term to short-term on our condensed consolidated balance sheets. For a discussion
In light of changes made to thethis material weakness, in preparing our condensed consolidated financial statements as of and for the quarter ended December 31, 2018, we performed additional procedures including a comprehensive review of our compliance with our various debt and lease agreements designed to ensure that were not related to the material weakness described below, see Note 1 in the “Notes to Condensed Consolidated Financial Statements”our condensed consolidated financial statements included elsewhere in this Quarterly Report.
MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
Our management is responsibleReport on Form 10-Q for establishing and maintaining adequate internal control over our financial reporting, as such term is defined in Exchange Act Rules13a-15(f) and 15d-15(f). The Company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposesquarter ended December 31, 2018, have been prepared in accordance with GAAP. A company’s internal control over financial reporting includes those policies and procedures that:generally accepted accounting principles.
pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company;
provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and
provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or because the degree of compliance with policies or procedures may deteriorate.
A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis.
Subsequent to the assessment made in connection with the Original Filing, our management, including our CEO and CFO, with the oversight of our Board of Directors, re-evaluated the effectiveness of the design and operation of our internal control over financial reporting as of March 31, 2018. The assessment was based on criteria established by the Committee of Sponsoring Organizations of the Treadway Commission in 2013 in Internal Control - Integrated Framework.  In connection with this assessment, management identified the following deficiency that we considered a material weakness in the Company’s internal control over financial reporting. We did not appropriately consider the requirements under certain of our secured financing and lease agreements and our obligation to monitor compliance with the underlying non-financial covenants.  As such, we did not appropriately consider the related financial reporting risks and changes in our lending agreements resulting in not implementing controls to determine compliance with non-financial covenants in certain of our secured financing and lease agreements.
The material weakness did not result in any corrected misstatements to the financial statements and there were no changes in previously released financial results as a result of the material weakness. Because of the material weakness described above, management concluded that, as of March 31, 2018, our internal control over financial reporting was not effective. For a discussion of changes made to the financial statements that were not related to the material weakness, see Note 1 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report.

The effectiveness of the Company’s internal control over financial reporting as of March 31, 2018 has been audited by KPMG, and KPMG has issued an adverse opinion on the effectiveness of the Company’s internal control over financial reporting as of March 31, 2018, which is included in our Amended 10-K.
Remediation Plan
Although certain procedures have been undertaken as a result of the material weakness, to assess compliance with non-financial covenants of certain of our secured equipment financing and lease agreements to remediate the material weakness, we will continue the implementation of our remediation plan by establishing a debt and lease compliance program with the specific objective of creating a sustainable and executable compliance process that can be repeated on a recurring basis to ensure timely monitoring of compliance with covenants and provisions. We intend to implement such compliance program by executing the following:
Development of a more complete reporting process to ensure information gathered or created by our separate control processes throughout the business are reported to the appropriate level of management with the responsibility for reporting on debt and lease agreement compliance.
Implementation of new or redesigned processes, where necessary, for compliance with collateral maintenance requirements under our debt and lease agreements, specifically, tracking the movement of collateral throughout our operations.
Establishment of procedures for reassessment of our debt and lease compliance program to ensure timely actions are taken when necessary.
We anticipate the actions to be taken, and resulting process improvements, will generally strengthen our internal controls over financial reporting, as well as our disclosure controls and procedures, and over time, will address the material weakness. The material weakness will be considered remediated once these controls have operated for a sufficient period of time for management to conclude, through testing, that these controls are operating effectively.
MATERIAL CHANGES IN INTERNAL CONTROLEvaluation of Disclosure Controls and Procedures
At the end of the period covered by this Quarterly Report on Form 10-Q, we carried out an evaluation, under the supervision of and with the participation of our management, including L. Don Miller, our Chief Executive Officer (“CEO”), and Brian J. Allman, our Chief Financial Officer (“CFO”), of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act of 1934, as amended (“Exchange Act”)). Based upon that evaluation and the evaluation of the previously identified material weakness in our internal controls over financial reporting for monitoring of

compliance with non-financial covenants within certain secured financing and lease agreements disclosed in the Amendment, our CEO and CFO have concluded our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) were not effective to provide reasonable assurance that the information required to be disclosed in the reports we file and submit under the Exchange Act is recorded, processed, summarized and reported within the time period specified in the Securities and Exchange Commission’s rules and forms and that information relating to us (including our consolidated subsidiaries) required to be disclosed is accumulated and communicated to management, including the CEO and CFO, to allow timely decisions regarding required disclosure.
Changes in Internal Control Over Financial Reporting
Other than the material weakness discussedchanges resulting from the debt and lease compliance remediation activities described above, our management, including the CEO and CFO, identified no change in our internal control over financial reporting that occurred during our fiscal quarter ended September 30,December 31, 2018, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.



PART II — OTHER INFORMATION
 
Item 1.    Legal Proceedings.
We have certain actions or claims pending that have been discussed and previously reported in Part I. Item 3. “Legal Proceedings” in the fiscal year 2018 Annual Report.Report, other than the item discussed below. Developments in these previously reported matters, if any, are described in Note 78 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report.
Sikorsky Lawsuit
On January 8, 2019, Bristow filed suit in the District Court of Harris County, Texas against Sikorsky Aircraft Corporation (“Sikorsky”) for breach of contract, unjust enrichment and conversion as a result of Sikorsky terminating a sales agreement after we sought to delay delivery of a helicopter and retaining our $11.7 million deposit as liquidated damages. We are seeking a ruling that Sikorsky be required to return the deposit and provide an accurate calculation of its damages under the sales agreement. Sikorsky has challenged venue, and discovery related thereto is underway. With the advice of counsel, we are evaluating the feasibility of transferring the matter to the Bankruptcy Court for disposition.
Huntington Lawsuit
The Huntington National Bank (“Huntington”) filed suit against the Company and Bristow U.S. LLC in the U.S. District Court for the Southern District of New York (the “Southern District of New York Court”). Huntington alleges violation of an addendum of a lease agreement for failure to arrange for the enrollment of the aircraft engines in a maintenance agreement and seeks approximately $2.5 million in damages. We submitted a counterclaim for approximately $100,000 of costs related to storage, maintenance and insurance of the aircraft following the expiration of the lease. On March 1, 2019, the Southern District of New York Court denied Huntington’s motion for summary judgment. We initiated discovery; however, on May 16, 2019, the proceedings were stayed as a result of the Chapter 11 Cases.
Federal Securities Class Action
Two purported class action complaints, Kokareva v. Bristow Group Inc., Case No. 4:19-cv-0509 and Lilienfield v. Bristow Group Inc., Case No. 4:19-cv-1064, were filed in the U.S. District Court for the Southern District of Texas (the “Southern District of Texas Court”) on February 14, 2019 and March 21, 2019, respectively. The complaints, which also name Jonathan E. Baliff and L. Don Miller as defendants, allege violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 arising out of the Company’s disclosures and alleged failure to make timely disclosure of inadequate monitoring control processes related to non-financial covenants within certain of its secured financing and lease agreements.  On May 17, 2019, the Southern District of Texas Court appointed BRS Investor Group as Lead Plaintiff and consolidated both actions under Kokareva v. Bristow Group Inc., Case No. 4:19-cv-0509. 
When the Company filed the Chapter 11 Cases on May 11, 2019, the litigation against the Company was automatically stayed.  The case was not automatically stayed against the individual defendants, but the Company intends to request that the stay also extend to the individual defendants.  On May 31, 2019, the Lead Plaintiff requested that the Southern District of Texas Court schedule an initial conference, and the defendants requested that any conference be postponed until after the Bankruptcy Court decides whether the stay should extend to the individual defendants.  The Southern District of Texas Court has not yet set a date for an initial conference.  The defendants believe that the claims are without merit and intend to vigorously defend against them.
Stockholder Derivative Complaint
On June 7, 2019, Marilyn DeVault filed a Stockholder Derivative Complaint against Thomas N. Amonett, Gaurdie Banister Jr., Ian A. Godden, Lori A. Gobillot, A. William Higgins, Thomas C. Knudson, Biggs C. Porter, Jonathan E. Baliff, Stephen A. King, Matthew Masters, David C. Gompert, Bruce H. Stover, L. Don Miller, and Brian J. Allman (the “Derivative Defendants”) in the United States District Court for the District of Delaware. The complaint alleges breaches of fiduciary duties and violations of Section 10(b) of the Securities Exchange Act of 1934 arising out of Company disclosures and failing to have adequate monitoring control processes related to non-financial covenants within certain of our secured financing and lease agreements. The complaint also alleges waste of corporate assets, gross mismanagement, and unjust enrichment.  The Derivative Defendants believe that the claims are without merit and intend to vigorously defend against them.



Item 1A. Risk Factors.
There have been no material changes during the three and sixnine months ended September 30,December 31, 2018 in our “Risk Factors” as discussed in the fiscal year 2018 Annual Report, originally filed with the SEC on May 23, 2018, or in our Quarterly Report on Form 10-Q for the three months ended September 30, 2018, originally filed with the SEC on November 9, 2018, other than the following:
Risks Related to Our Chapter 11 Cases
On May 11, 2019, Bristow and certain of its subsidiaries filed voluntary petitions commencing the Chapter 11 Cases under the Bankruptcy Code. The Columbia AcquisitionChapter 11 Cases and the Restructuring may have a material adverse impact on our business, financial condition, results of operations, and cash flows. In addition, the Chapter 11 Cases and the Restructuring may have a material adverse impact on the trading price and may result in the cancellation and discharge of our securities, including our common stock. If approved by the Bankruptcy Court, the Plan will govern distributions to and the recoveries of holders of our securities. 
As previously disclosed in our Current Report on Form 8-K filed with the SEC on April 15, 2019, we engaged financial and legal advisors to assist us in, among other things, analyzing various strategic financial alternatives to address our liquidity and capital structure, including strategic financial alternatives to restructure our indebtedness. These efforts led to the execution of the RSA on May 10, 2019 and the commencement of the Chapter 11 Cases in the Bankruptcy Court on May 11, 2019.  
The Chapter 11 Cases could have a material adverse effect on our business, financial condition, results of operations and liquidity. So long as the Chapter 11 Cases continue, our management may be required to spend a significant amount of time and effort dealing with the restructuring instead of focusing on our business operations. Bankruptcy Court protection and operating as debtors in possession also may make it more difficult to retain management and the key personnel necessary to the success and growth of our business. In addition, during the pendency of the Chapter 11 Cases, our customers and suppliers might lose confidence in our ability to reorganize our business successfully and may seek to establish alternative commercial relationships, which may cause, among other things, our suppliers, vendors, counterparties and service providers to renegotiate the terms of our agreements, attempt to terminate their relationship with us or require financial assurances from us. Although we remain committed to providing safe, reliable operations and we believe that we have sufficient resources to do so, customers may lose confidence in our ability to provide them the level of service they expect, resulting in a significant decline in our revenues, profitability and cash flow.
Other significant risks include or relate to the following:
our ability to obtain the Bankruptcy Court’s approval with respect to motions or other requests made to the Bankruptcy Court in the Chapter 11 Cases, including maintaining strategic control as debtor-in-possession;
our ability to consummate a Chapter 11 plan and emerge from bankruptcy protection;
the effects of the filing of the Chapter 11 Cases on our business and the interest of various constituents, including our stockholders;
increased advisory costs to execute our reorganization;
our ability to maintain relationships with suppliers, customers, employees and other third parties as a result of the Chapter 11 Cases;
Bankruptcy Court rulings in the Chapter 11 Cases as well as the outcome of other pending litigation and the outcome of the Chapter 11 Cases in general;
the length of time that we will operate with Chapter 11 protection and the continued availability of operating capital during the pendency of the proceedings;
third-party motions in the Chapter 11 Cases, which may interfere with our ability to consummate a Chapter 11 plan; and
the potential adverse effects of the Chapter 11 Cases on our liquidity and results of operations.
Further, under Chapter 11, transactions outside the ordinary course of business are subject to the prior approval of the Bankruptcy Court, which may limit our ability to respond in a timely manner to certain events or take advantage of certain opportunities or to adapt to changing market or industry conditions.


Because of the risks and uncertainties associated with the Chapter 11 Cases, we cannot predict or quantify the ultimate impact that events occurring during the Chapter 11 Cases may have on our business, cash flows, liquidity, financial condition and results of operations, nor can we predict the ultimate impact that events occurring during the Chapter 11 Cases may have on our corporate or capital structure. 
Delays in the Chapter 11 Cases may increase the risks of our being unable to reorganize our business and emerge from bankruptcy and increase our costs associated with the bankruptcy process.
The RSA contemplates the filing and confirmation of a Chapter 11 plan that implements the Restructuring (the “Plan”); however, certain terms of the Plan have not yet been specified and there can be no assurance that the Plan will be accepted by stakeholders that are entitled to vote or approved by the Bankruptcy Court, or that the Plan will become effective in accordance with its terms. Prolonged Chapter 11 proceedings could adversely affect our relationships with customers, suppliers and employees, among other parties, which in turn could adversely affect our business, competitive position, financial condition, liquidity and results of operations and our ability to continue as a going concern. A weakening of our financial condition, liquidity and results of operations could adversely affect our ability to implement the Plan (or any other Chapter 11 plan). If we are unable to consummate the Plan, we may be forced to liquidate our assets.
Trading in our common stock during the pendency of our Chapter 11 Cases is highly speculative and poses substantial risks.
All of our indebtedness is senior to the existing common stock in our capital structure. The treatment of holders of our existing common stock under the transactions contemplated by the RSA has not been determined; however, our common stock is likely to be cancelled under the Plan or otherwise in connection with the Chapter 11 Cases. Trading prices for our common stock may bear little or no relationship to the actual recovery, if any, by holders of our common stock in the Chapter 11 Cases. Accordingly, any trading in our common stock during the pendency of our Chapter 11 Cases is highly speculative and poses substantial risks to purchasers of our common stock.
The RSA is subject to significant conditions and milestones that may be difficult for us to satisfy. 
There are certain material conditions we must satisfy under the RSA, including certain conditions thatthe timely satisfaction of milestones in the Chapter 11 Cases, which include the consummation of the Plan. Our ability to timely complete such milestones is subject to risks and uncertainties, many of which are beyond our control.
We may not be satisfied,able to obtain confirmation of the Plan.
In order to emerge successfully from the Chapter 11 Cases as a reorganized entity, we must meet certain statutory disclosure requirements with respect to adequacy of disclosure with respect to the Plan, solicit and obtain the requisite acceptances of the Plan and fulfill other statutory conditions for confirmation of the Plan, most of which have not occurred to date. The confirmation process is subject to numerous, unanticipated potential delays, including a delay in the Bankruptcy Court’s commencement of the confirmation hearing regarding the Plan. There is no assurance that the Plan, when filed, or any subsequent amendments thereto, will be confirmed and become effective.
If the Plan is not confirmed by the Bankruptcy Court, it is unclear whether we would be able to reorganize our business and what, if anything, holders of claims and equity interests against us would ultimately receive with respect thereto.
Even if a Chapter 11 plan of reorganization is consummated, we may not be completedable to achieve our stated goals and there is substantial doubt regarding our ability to continue as a going concern. 
Even if the Plan or any other Chapter 11 plan of reorganization is consummated, we may continue to face a number of risks, such as changes in economic conditions, changes in our industry, changes in demand for our services and increasing expenses. Some of these risks become more acute when a case under the Bankruptcy Code continues for a protracted period without indication of how or when the case may be completed. As a result of these risks and others, we cannot guarantee that any Chapter 11 plan of reorganization will achieve our stated goals. 
Furthermore, even if our debts are reduced or discharged through a plan of reorganization, we may need to raise additional funds through public or private debt or equity financing or other various means to fund our business after the completion of the Chapter 11 Cases. Our access to additional financing may be limited, if it is available at all. Therefore, adequate funds may not be available when needed or may not be available on favorable terms, or at all. 
As a result of the Chapter 11 Cases, even with certain creditor support for the restructuring under the RSA, there is substantial doubt regarding our ability to continue as a going concern. As a result, we cannot assure you of our ability to continue as a going concern. 

Our long-term liquidity requirements and the adequacy of our capital resources are difficult to predict at this time.
We face uncertainty regarding the adequacy of our liquidity and capital resources and have extremely limited, if any, access to additional financing. In addition to the cash requirements necessary to fund ongoing operations, we have incurred significant professional fees and other costs in connection with preparation for the Chapter 11 Cases and expect that we will continue to incur significant professional fees and costs throughout our Chapter 11 Cases. We cannot assure you that cash on hand and cash flow from operations will be sufficient to continue to fund our operations and allow us to satisfy our obligations related to the Chapter 11 Cases until we are able to emerge from our Chapter 11 Cases. Although we entered into the Term Loan Agreement prior to our Chapter 11 Cases and have received commitments for a $75.0 million DIP Facility in connection with the Chapter 11 Cases and the RSA contemplates $200 million of new equity financing through the Rights Offering, we cannot assure you that such financing sources will be sufficient, that the DIP Facility will be approved by the Bankruptcy Court, that we will be able to secure additional interim financing or adequate exit financing sufficient to meet our liquidity needs (or if sufficient funds are available, that they will be offered to us on acceptable terms) or that we will successfully complete the Rights Offering.
Our liquidity, including our ability to meet our ongoing operational obligations, is dependent upon, among other things: (i) our ability to comply with the terms and conditions of any order governing the use of cash collateral that may be entered by the Bankruptcy Court in connection with the Chapter 11 Cases, (ii) our ability to maintain adequate cash on hand, (iii) our ability to generate cash flow from operations, (iv) our ability to enter into and borrow under the DIP Facility, (v) our ability to develop, confirm and consummate the Plan or other alternative restructuring transaction, and (vi) the cost, duration and outcome of the Chapter 11 Cases.
In certain instances, a Chapter 11 case may be converted to a case under Chapter 7 of the Bankruptcy Code. 
Upon a showing of cause, the Bankruptcy Court may convert our Chapter 11 Cases to a case under Chapter 7 of the Bankruptcy Code. In such event, a Chapter 7 trustee would be appointed or elected to liquidate our assets for distribution in accordance with the priorities established by the Bankruptcy Code. We believe that liquidation under Chapter 7 would result in significantly smaller distributions being made to our creditors than those provided for in the Plan because of (i) the likelihood that the assets would have to be sold or otherwise disposed of in a distressed fashion over a short period of time rather than in a controlled manner and as a going concern, (ii) additional administrative expenses involved in the appointment of a Chapter 7 trustee, and (iii) additional expenses and claims, some of which would be entitled to priority, that would be generated during the liquidation and from the rejection of leases and other executory contracts in connection with a cessation of operations.
As a result of the Chapter 11 Cases, our historical financial information may not be indicative of our future performance, which may be volatile. 
During the Chapter 11 Cases, we expect our financial results to continue to be volatile as restructuring activities and expenses, contract terminations and rejections, and claims assessments significantly impact our consolidated financial statements. As a result, our historical financial performance is likely not indicative of our financial performance after the date of the filing of the Chapter 11 Cases. In addition, if we emerge from Chapter 11, the amounts reported in subsequent consolidated financial statements may materially change relative to our historical consolidated financial statements. We also may be required to adopt fresh start accounting, in which case our assets and liabilities will be recorded at fair value as of the fresh start reporting date, which may differ materially from the recorded values of assets and liabilities on our consolidated balance sheets. Our financial results after the application of fresh start accounting may be different from historical trends.
We may be subject to claims that will not be discharged in the Chapter 11 Cases, which could have a material adverse effect on our financial condition and results of operations. 
The Bankruptcy Court provides that the confirmation of a plan of reorganization discharges a debtor from, among other things, substantially all debts arising prior to consummation of a plan of reorganization. With few exceptions, all claims against the Debtors that arose prior to May 11, 2019 or before consummation of the Plan (i) would be subject to compromise and/or treatment under the Plan and/or (ii) would be discharged in accordance with the Bankruptcy Code and the terms of the Plan. Subject to the terms of the Plan and orders of the Bankruptcy Court, any claims not ultimately discharged pursuant to the Plan could be asserted against the reorganized entities and may have an adverse effect on our financial condition and results of operations on a post-reorganization basis.

We may experience employee attrition as a result of the Chapter 11 Cases. 
As a result of the Chapter 11 Cases, we may experience employee attrition, and our employees may face considerable distraction and uncertainty. A loss of key personnel or material erosion of employee morale could adversely affect our business and results of operations. Our ability to engage, motivate and retain key employees or take other measures intended to motivate and incentivize key employees to remain with us through the pendency of the Chapter 11 Cases is limited by restrictions on implementation of incentive programs under the Bankruptcy Code. The loss of services of members of our senior management team could impair our ability to execute our strategy and implement operational initiatives, which would be likely to have a material adverse effect on our financial condition, liquidity and results of operations. 
Risks Related to Our Business
We have identified a material weakness in our internal control over financial reporting, which could, if not remediated, adversely affect our ability to report our financial condition and results of operations in a timely and accurate manner, investor confidence in our company and the value of our common stock.
As described in Part I. Item 4. “Controls and Procedures” of this Quarterly Report, management has concluded that the Company did not have adequate monitoring control processes in place related to non-financial covenants within certain of its secured financing and lease agreements, and this control deficiency identified represents a “material weakness” in internal controls over financial reporting. A “material weakness” is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the Company’s annual or interim financial statements will not be prevented or detected on a timely basis. As a result of such material weakness, our management concluded that our disclosure controls and procedures and internal control over financial reporting were not effective at a reasonable assurance level as of March 31, 2018 and the reporting periods thereafter.
The determination of the existence of a control deficiency related to these matters, which has been classified as a material weakness in our internal controls over financial reporting, and the need to assess possible non-compliance with all non-financial covenants commenced when our senior management became aware that certain pledged and leased helicopter engines were not matched to specific pledged or leased helicopter airframes or returned to such airframes within specified periods, as required under certain of the secured financing and helicopter lease agreements. The removal and replacement of engines and components from helicopters is part of our normal ongoing maintenance activities; however, since certain of those helicopter engines and airframes are pledged to lenders or leased from lessors, the removal of a pledged or leased engine from a pledged or leased airframe can create issues of non-compliance with certain of the secured financing and helicopter lease agreements. All issues related to this matter were cured prior to December 31, 2018 for all but nine helicopter engines (relating to three agreements) where the pledged or leased engines were not returned to the pledged or leased airframes within specified periods due to delays with certain of our maintenance service providers. We have obtained waivers of such non-compliance under the applicable agreements related to such helicopter engines. We are in the process of remediating this material weakness, but our remediation efforts are not yet complete. There can be no assurance as to when the remediation plan will be fully implemented or whether the remediation efforts will be successful.
Until our remediation plan is fully implemented, our management will continue to devote time and attention to these efforts. If we do not complete our remediation in a timely fashion, or at all, or if our remediation plans are inadequate, our future consolidated financial statements could contain errors that may be undetected. The existence of a material weakness in the effectiveness of our internal controls could also affect our ability to obtain financing or could increase the cost of any financing we obtain. The identification of the material weakness could also cause investors to lose confidence in the reliability of our financial statements and could result in a decrease in the value of our common stock.

The consolidated financial statements included in our Amended 10-K and in this Quarterly Report do, and the consolidated financial statements to be included in our Annual Report on Form 10-K for the fiscal year ended March 31, 2019 will, contain disclosures that express substantial doubt about our ability to continue as a going concern, indicating the possibility that we may not be able to operate in the future.
The consolidated financial statements included in the Amended 10-K and in this Quarterly Report have been, and the consolidated financial statements to be included in our Annual Report on Form 10-K for the fiscal year ended March 31, 2019 will be, prepared on a going concern basis, if at all. Failurewhich contemplates the realization of assets and the satisfaction of liabilities and other commitments in the normal course of business and does not include any adjustments that might result from uncertainty about our ability to completecontinue as a going concern. Such assumption may not be justified. Our liquidity has been negatively impacted by the Columbia Acquisition, or significant delaysprolonged downturn in completing the Columbia Acquisition, couldoffshore oil and gas market, our levels of indebtedness, lease and aircraft purchase commitments and certain other commercial contracts. In addition, we have substantial interest payment obligations related to our debt and substantial lease and aircraft purchase commitments over the next twelve months. If we are unable to execute transactions to improve our financial condition, we do not believe we will have sufficient liquidity to conduct our business operations based on existing conditions and estimates during the next twelve months. If we become insolvent, investors in our common stock may lose the entire value of their investment in our business. The inclusion of disclosures that express substantial doubt about our ability to continue as a going concern may negatively affectimpact the trading pricesprice of our common stock and have an adverse impact on our futurerelationship with third parties with whom we do business, financial conditionincluding our customers, vendors and results of operations.
The completion ofemployees, and could make it challenging and difficult for us to raise additional debt or equity financing to the Columbia Acquisition is subject to a number of conditions contained in the Purchase Agreement that must be satisfiedextent needed, on attractive terms or waived prior to completion of the acquisition. We cannot predict whether and when these other conditions will be satisfied. Any delay in completing the Columbia Acquisition could cause us not to realize some orat all, all of the anticipated benefits of our ownership of Columbia if the Columbia Acquisition is successfully completed within its expected time frame.
If the Columbia Acquisition is not completed, we will be subject to several risks and consequences, including the following:
certain damages for which the parties may be liable to one another under the terms and conditions of the Purchase Agreement;
negative reactions from the financial markets, including declines in the price of our common stock due to the fact that current prices may reflect a market assumption that the Columbia Acquisition will be completed;
certain significant costs relating to the Columbia Acquisition and the related financing, including, in certain circumstances, a termination fee payable by us of $20.0 million; and
diverted attention of our management to the Columbia Acquisition and the process of completing the related financing rather than to our own operations and pursuit of other opportunities that could have been beneficial to us.

We will be subject to various limitations while the Columbia Acquisition is pending that could adversely affecta material adverse impact on our business, financial condition and results of operations.
UnderOur common stock has been delisted from the termsNew York Stock Exchange.
Our common stock was previously listed on the New York Stock Exchange (the “NYSE”) under the symbol “BRS.” As a result of our failure to satisfy the continued listing requirements of the Purchase Agreement, we are restrictedNYSE, on May 13, 2019, our common stock was delisted from takingthe NYSE. Since May 14, 2019, our common stock has been trading on the OTC Pink Marketplace maintained by the OTC Markets Group, Inc. under the symbol “BRSWQ.” We can provide no assurance that our common stock will continue to trade on this market, whether broker-dealers will continue to provide public quotes of our common stock on this market, whether the trading volume of our common stock will be sufficient to provide for an efficient trading market or whether quotes for our common stock will continue on this market in the future. See “— Risks Related to Our Chapter 11 Cases — Trading in our common stock during the pendency of our Chapter 11 Cases is highly speculative and poses substantial risks.”
If certain specified actions priortransactions occur with respect to completing the Columbia Acquisition, whichour capital stock, limitations may adversely affectbe imposed on our ability to executeutilize net operating loss carryforwards to reduce our income taxes.
Under federal income tax law, a corporation generally is permitted to carry forward net operating losses from prior tax years to offset taxable income, and correspondingly reduce federal income tax liability, in later tax years. We estimate having net operating loss carryforwards for federal income tax purposes of approximately $145.0 million as of March 31, 2019. Our ability to utilize our net operating loss carryforwards to offset future taxable income and reduce federal income tax liability is subject to certain requirements and restrictions. In particular, if we experience an “ownership change,” as defined in section 382 of the U.S. Internal Revenue Code, then our business strategies. Such limitationsability to use our net operating loss carryforwards may be substantially limited, which could negatively affecthave a negative impact on our business, financial conditionposition and results of operationsoperations. Generally, there is an “ownership change” if one or more shareholders owning 5% or more of a corporation’s common stock have aggregate increases in their ownership of such stock of more than 50% over a rolling three-year period. Thus, if certain transactions occur with respect to our capital stock (including issuances, redemptions, recapitalizations, exercises of options, conversions of convertible debt, purchases or sales by 5%-or-greater shareholders and similar transactions) that result in a cumulative change of more than 50% of the ownership of capital stock over the relevant three-year period, an annual limitation would be imposed with respect to the ability to utilize our net operating loss carryforwards that existed at the time of the ownership change.
Under section 382 of the U.S. Internal Revenue Code, absent an application exception (including any exception available for ownership changes occurring in connection with a bankruptcy reorganization), if a corporation undergoes an “ownership change,” the amount of its net operating losses existing as of the time of the ownership change that may be utilized to offset future taxable income generally will be subject to an annual limitation equal to the value of its stock immediately prior to the completion ofownership change multiplied by the Columbia Acquisition.
We will incur substantial transaction fees and costslong-term tax-exempt rate (plus an additional amount calculated based on certain “built in connection withgains” in our assets that may be deemed to be realized within a 5-year period following any ownership change). Because the Columbia Acquisition.
We expect to incur a number of non-recurring transaction-related costs associated with negotiating and completing the Columbia Acquisition, integrating ownership of Columbia into our business and achieving the anticipated benefitsvalue of our stock can be subject to significant fluctuations in value, it is possible an ownership of Columbia. These fees and costs are expectedchange would materially limit our ability to be substantial. Non-recurring transaction costs include, but are not limited to, employment-related costs, fees paid to legal, financial and accounting advisors and filing fees. Additional unanticipated costs may be incurredutilize our substantial net operating loss carryforwards in integrating ownership of Columbia into our business. Therethe future. As such, there can be no assurance that the benefits of the Columbia Acquisition will exceed these transaction-related costs.
If completed, the Columbia Acquisition may not achieve its intended results, and we may be unable to successfully realize expected benefits. Failure to successfully realize expected benefits in the anticipated time frame may adversely affect our future results, and, consequently, the value of our common stock.
We entered into the Purchase Agreement with the expectation that the Columbia Acquisition will result in various benefits, including, among other things, expanding our fleet and market diversification. Achieving the anticipated benefits of our ownership of Columbia is subject to a number of uncertainties. In addition, it is possible that following the Columbia Acquisition, we experience

the loss of valuable employees, the disruption of each company’s ongoing businesses, processes and systems or inconsistencies in standards, controls, procedures, practices, policies and compensation arrangements, any of which could adversely affect our ability to achieve the anticipated benefits of our ownership of Columbia. Our results of operations could also be adversely affected by any issues attributable to either company’s operations that arise from or are based on events or actions that occur prior to the completion of the Columbia Acquisition. Acquisitions are inherently subject to a number of uncertainties, and no assurance can be given that the anticipated benefits will be realized or, if realized, the timing of their realization. Failure to achieve these anticipated benefits could result in increased costs or decreases in the amount of expected revenues and could adversely affect our future business, financial condition, results of operations and prospects.
In addition, the market price of our common stock may decline as a result of the Columbia Acquisition if, among other things, we do not achieve the anticipated benefits of our ownership of Columbia as rapidly or to the extent anticipated by us or by securities market participants or if the effect of the Columbia Acquisition, including the obligations incurred to finance the Columbia Acquisition, on our business results of operations, financial condition or prospects is not consistent with our expectations or those of securities market participants.
If a governmental authority asserts objections to the Columbia Acquisition, we may be unable to complete the Columbia Acquisition or, in order to do so, we may be required to comply with certain restrictions or conditions.
The completion of the Columbia Acquisition is subject to the condition that there is no injunction, judgment or ruling by a governmental authority in effect enjoining, restraining, preventing or prohibiting consummation of the Columbia Acquisition contemplated by the Purchase Agreement. If a governmental authority asserts objections to the Columbia Acquisition, we may be required to accept restrictions or other remedies in order to complete the Columbia Acquisition. There can be no assurance as to the cost, scope or impact of the actions that may be required to address any governmental authority objections to the Columbia Acquisition. If either company takes such actions, it could be detrimental to it or to the combined company following the consummation of the Columbia Acquisition. Furthermore, these actions could have the effect of delaying or preventing completion of the Columbia Acquisition or imposing additional costs on us or negatively affecting our revenues following the consummation of the Columbia Acquisition.
We may have difficulty motivating and retaining executives and other employees of Columbia in light of the Columbia Acquisition.
Uncertainty about the effect of the Columbia Acquisition on Columbia employees may impair Columbia’s and our ability to motivate and retain such personnel until and after the Columbia Acquisition is completed. Employee retention may be particularly challenging during the pendency of the Columbia Acquisition, as employees may feel uncertain about their future roles following the Columbia Acquisition. In addition, we may have to provide additional compensation in order to retain employees. If Columbia’s employees depart because of issues relating to the uncertainty and difficulty of integration or a desire not to become employees of the company following the Columbia Acquisition, our ability to realize the anticipated benefits of our ownership of Columbia could be adversely affected.
In connection with the Columbia Acquisition, we and Columbia will incur substantial indebtedness, which could adversely affect us and Columbia, including by inhibiting our flexibility and imposing significant interest expense on our respective businesses.
In connection with the Columbia Acquisition, we will issue $135 million of secured convertible senior notes and Columbia is expected to issue $360 million of senior secured notes. Such indebtedness and obligations could have the effect, among other things, of inhibiting the combined business’ flexibility to respond to changing business and economic conditions and imposing significant interest expense. In addition, the amount of cash required to pay interest on the such obligations following completion of the Columbia Acquisition, and thus the demands on both our and Columbia’s cash resources, will be significant. The levels of indebtedness following completion of the Columbia Acquisition could therefore reduce funds available for working capital, capital expenditures, acquisitions and other general corporate purposes and may create competitive disadvantages for the combined business relative to other companies with lower debt levels. In addition, concerns about the debt levels of the combined business could have an adverse impact on our ability to obtain new contract awards from customers, and on the commercial terms we obtain from customers, including with respect to letter of credit and performance guaranty requirements.
We and Columbia may be required to raise additional financing for working capital, capital expenditures, acquisitions or other general corporate purposes. Our and Columbia’s ability to arrange additional financing or refinancing will depend on, among other factors, our and Columbia’s financial position and performance, as well as prevailing market conditions and other factors beyond our or Columbia’s control. We cannot assure you that we or Columbia will be able to obtain additional financing or refinancing on acceptable terms or at all.utilize our net operating loss carryforwards to offset future taxable income.

On May 14, 2019, in connection with our Chapter 11 Cases, the Bankruptcy Court entered an order approving certain notification and hearing procedures for transfers of, and declarations of worthlessness with respect to, beneficial ownership of common stock (the “Order”). The agreements governingOrder is designed to protect our indebtedness will,net operating loss carryforwards from the effect of a premature ownership change under section 382 of the Internal Revenue Code, and the agreements governing Columbia’s indebtedness are expected to impose restrictions onpreserve our ability to engagerely on certain favorable rules that can apply to ownership changes occurring in transactionsconnection with Columbiathe implementation of a bankruptcy plan of reorganization. The Order requires “substantial shareholders” and could affect our ability“50-percent shareholders” (each as defined therein), and certain persons that might become a substantial shareholder or 50-percent shareholder, to realize the anticipated benefitsprovide notice before making certain transfers of ourbeneficial ownership of Columbia.
We anticipate that Columbia will be an unrestricted subsidiary under our applicable existing credit agreements and the indentures governing our outstanding notes. Columbia is expected to issue senior notes to finance a portion of the purchase price for the Columbia Acquisition. The agreements governing our indebtedness will limit our ability to engage in transactions with Columbia except on an arms’ length basis, and the agreements governing Columbia’s indebtedness are expected to contain similar restrictions on Columbia’s ability to engage in transactions with us except on an arms’ length basis, as well as limitations on Columbia’s ability to distribute funds to us. As a result, our ability to realize the full anticipated benefits of ourcommon stock or declaring its beneficial ownership of Columbia will be limited while Columbia’s indebtednessstock worthless for U.S. federal income tax purposes, respectively. After receiving notice, we are permitted to object, whereupon such action remains outstanding.ineffective pending final resolution. Any action taken in violation of such procedures is void ab initio.
