EXPLANATORY NOTE

This Amended Annual Report on Form 10-K/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 Annual Report on Form 10-K for the year ended March 31, 2018, originally filed with the U.S. Securities and Exchange Commission (the “SEC”) on May 23, 2018 (the “Original Filing” and, as amended by this Amendment No. 1, this “Amended 10-K”), to (i) reflect a change in management’s assessment of our disclosure controls and procedures, (ii) revise the Company’s previously reported consolidated financial statements to reclassify substantially all debt balances from long-term to short-term, include disclosures regarding the Company’s ability to continue as a going concern and for immaterial corrections to prior years’ financial information as explained in Notes 1 and 4 in the “Notes to Consolidated Financial Statements” included elsewhere in this Annual Report, (iii) restate Management’s Report on Internal Control Over Financial Reporting and (iv) include revised reports of KPMG LLP (“KPMG”), our Independent Registered Public Accounting Firm, with respect to its audits of the Company’s Internal Control Over Financial Reporting and on the 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. The revised report of KPMG on the consolidated financial statements included in this Amended 10-K includes an explanatory paragraph expressing uncertainty as to the Company’s ability to continue as a going concern. As a result of the delivery of this Amended 10-K with a going concern qualification or explanation included in the accompanying report of the Company’s independent registered public accounting firm, 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 this Amendment No. 1.

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”) 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.

• the first paragraph of “Executive Overview” in Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations; and the captions “Liquidity and Capital Resources — Future Cash Requirements — Debt Obligations”, “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 II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations;

•Part II, Item 8. Consolidated Financial Statements and Supplementary Data;

•Part II, Item 9A. Controls and Procedures; and

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 IV, Item 15(a)(3) to reflect the filing of these currently dated certifications.

In addition, this Amendment No. 1 contains the revised reports of KPMG required pursuant to Item 308(b) of Regulation S-K. Accordingly, this Amendment No. 1 (i) amends and restates Part II, Item 8. Consolidated Financial Statements and Supplementary Data and Part II, Item 9A. Controls and Procedures, in each case under the heading “Report of Independent Registered Public Accounting Firm,” to reflect the revised reports of KPMG and (ii) amends and restates Part IV, Item 15(a)(3) to reflect the filing of the consent related to the revised reports of KPMG.

We have also updated the signature page and our audited 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 March 31, 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 9A. Controls and Procedures included herein.

PART I

Item 1.    Business

Overview

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 Australia through our consolidated affiliates, Eastern Airways International Limited (“Eastern Airways”) and Capiteq Limited, operating under the name of Airnorth, respectively. These operations support our primary industrial aviation services operations in those markets, creating a more integrated logistics solution for our clients.

During fiscal year 2018, we generated approximately 68% of our consolidated operating revenue from external clients from oil and gas operations, approximately 17% from U.K. SAR operations and approximately 15% 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 clients charter our helicopters primarily to transport personnel between onshore bases and offshore production platforms, drilling rigs and other installations. To a lesser extent, our clients also charter our helicopters to transport time-sensitive equipment to these offshore locations. These clients’ 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 clients for SAR services include both the oil and gas industry, where our revenue is primarily dependent on our clients’ operating expenditures, and governmental agencies, where our revenue is dependent on a country’s desire to privatize SAR and enter into long-term contracts.

Helicopters are generally classified as small (four to eight passenger capacity), medium (12 to 16 passenger capacity) and large (16 to 25 passenger capacity), each of which serves a different transportation need of the offshore energy industry. Medium and large helicopters, which can fly in a wider variety of operating conditions, over longer distances, at higher speeds and carry larger payloads than small helicopters, are most commonly used for crew changes on large offshore production facilities and drilling rigs. With these enhanced capabilities, medium and large helicopters have historically been preferred in international markets, where the offshore facilities tend to be larger, the drilling locations tend to be more remote, located in harsh environments and the onshore infrastructure tends to be more limited. Additionally, local governmental regulations in certain international markets require us to operate twin-engine medium and large aircraft in those markets. Global demand for medium and large helicopters is driven by drilling, development and production activity levels in deepwater locations throughout the world, as the medium and large aircraft are able to travel to these deepwater locations. Small helicopters are generally used for shorter routes and to reach production facilities that cannot accommodate medium and large helicopters. Historically, our small helicopters have operated primarily over the shallow waters offshore in the U.S. Gulf of Mexico and Nigeria. We are able to deploy our aircraft to the regions with the greatest demand, subject to the satisfaction of local governmental regulations. SAR operations utilize medium and large aircraft that are specially configured to conduct these types of operations in environments around the world. The commercial aircraft in our consolidated fleet 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,

3

which excludes fixed wing aircraft, unconsolidated affiliate aircraft, aircraft held for sale and aircraft construction in process. 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. 

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 clients 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.

Our business has traditionally been significantly dependent upon the level of offshore oil and gas exploration, development and production activity. We have begun diversification with recent investments into other new business growth areas within the industrial aviation services to lessen the cyclical effects of a downturn in any one industry or economy. There are also additional markets for aviation services beyond the offshore energy industry and SAR, including air medical, agricultural support, corporate transportation, firefighting, military, police, tourism and traffic monitoring. The existence of these alternative markets enables us to better manage our helicopter fleet by providing potential purchasers for older aircraft and for our excess aircraft during times of reduced demand in the offshore energy industry.

Additionally, we have fixed wing operations in the U.K., Nigeria and Australia that create a more integrated logistics solution for our global clients and further diversify our business.

Most countries in which we operate limit foreign ownership of aviation companies. To comply with these regulations and at the same time expand internationally, we have formed or acquired interests in a number of foreign aviation operators. These investments typically combine a local ownership interest with our experience in providing industrial aviation services to the offshore energy industry. These arrangements have allowed us to expand operations while diversifying the risks and reducing the capital outlays associated with independent expansion. We lease some of our aircraft to a number of unconsolidated affiliates, which in turn provide industrial aviation services to clients locally.

We regularly engage in discussions with potential sellers and strategic partners regarding the possible purchase of assets, pursuit of joint ventures or other expansion opportunities that increase our position in existing markets or facilitate expansion into new markets. 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. These potential expansion opportunities and divestitures may consist of both smaller transactions as well as larger transactions that could have a material impact on our financial position, cash flow and results of operations. We cannot predict the likelihood of completing, or the timing of, any such transactions.

The oil and gas business environment experienced a significant downturn beginning during fiscal year 2015. Brent crude oil prices declined from approximately $106 per barrel at July 1, 2014 to a low of approximately $26 per barrel in February 2016, with an increase to approximately $65 per barrel as of March 31, 2018. The decrease in oil prices was driven by increased global supply 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 clients and resulted in their implementation of measures to reduce operational and capital costs, negatively impacting activity beginning in fiscal year 2015. These cost reductions have continued into fiscal year 2018 and have impacted both the offshore production and the offshore exploration activity of our clients, with offshore production activity being impacted to a lesser extent. Although the largest share of our revenue relates to oil and gas production and our largest contract, the U.K. SAR contract (as defined herein), is not directly impacted by declining oil prices, 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 since 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 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, which in turn reduces our oil and gas clients’ costs and generates increased demand for offshore transportation like helicopters. As discussed elsewhere in this Annual Report, our success in reducing costs 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 as 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.

Region Operations

Europe Caspian

Based on the number of aircraft operating, we are one of the largest providers of industrial aviation services in the North Sea, where there are harsh weather conditions and geographically concentrated offshore facilities. As of March 31, 2018, we operated our oil and gas operations in our Europe Caspian region from four bases in the U.K. and four bases in Norway. The offshore facilities in the Northern North Sea and Norwegian North Sea are large and require frequent crew change flight services. In the Southern North Sea, the facilities are generally smaller with some unmanned platforms requiring shuttle operations to up-man in the morning and down-man in the evening. We deploy the majority of the large aircraft in our consolidated fleet in the North Sea where our clients are primarily major integrated and independent offshore energy companies. Our North Sea operations are subject to seasonality as drilling activity is lower during the winter months due to harsh weather and shorter days.

We provide commercial SAR services for a number of oil and gas companies operating in the Norwegian sector of the North Sea.

We have a contract with the U.K. Department for Transport (the “DfT”) to provide public sector SAR services for all of the U.K. (the “U.K. SAR contract”). The U.K. SAR contract has a phased-in transition period that began in April 2015 and continued to July 2017 with a contract length of approximately ten years. We are currently operational at all ten bases as follows: Humberside and Inverness (April 2015), Caernarfon (July 2015), Lydd (August 2015), St. Athan (October 2015), Prestwick and Newquay (January 2016), Lee-on-Solent (March 2017), and two previously awarded Gap SAR bases of Sumburgh (June 2013) and Stornoway (July 2013). One Gap SAR base transitioned to the U.K. SAR contract on March 31, 2017 and the remaining Gap SAR base transitioned to the U.K. SAR contract on July 1, 2017. Although the U.K. SAR contract calls for 11 U.K. SAR configured S-92s and 11 U.K. SAR configured AW189s, as of March 31, 2018, we are servicing this contract utilizing the following U.K. SAR configured aircraft: 14 S-92s (11 of which are leased), nine AW189s (two of which are leased) and four AW139s (all four are leased).

Bristow Helicopters owns a 100% interest in Eastern Airways, a regional fixed wing operator based in the U.K. Eastern Airways has approximately 650 employees and its operations focus on providing scheduled and charter services targeting U.K. oil and gas transport. Eastern Airways operates 34 fixed wing aircraft and provides technical support for two fixed wing aircraft operating in our Africa region. We believe our investment in Eastern Airways strengthens our ability to provide a complete suite of point to point transportation services for existing European based passengers, expand industrial aviation services in certain areas like the Shetland Islands and create a more integrated logistics solution for global clients.

Additionally, our Europe Caspian region includes operations in Turkmenistan. We operate one medium aircraft through our 51% interest in Turkmenistan Helicopters Limited, a Turkmenistan corporation that provides industrial aviation services to an international offshore energy company from a single location.

7

Africa

As of March 31, 2018, most of the aircraft in our Africa region operated in Nigeria, where we are the largest provider of industrial aviation services to the offshore energy industry. We have historically deployed a combination of small, medium and large aircraft in Nigeria and service a client base comprised mostly of major integrated offshore energy companies. We have four operational bases located as follows: one in Lagos, one in Eket and two in Port Harcourt. The marketplace for our services had historically been concentrated predominantly in the oil rich swamp and shallow waters of the Niger Delta area. More recently we have been undertaking work further offshore in support of deepwater exploration. Operations in Nigeria are subject to seasonality as the Harmattan, a dry and dusty trade wind, blows between the end of December and the middle of February. At times when the heavy amount of dust in the air severely limits visibility, our aircraft are unable to operate.

In October 2015, we began providing fixed wing services to provide end-to-end transportation services for principally oil and gas industry customers and currently operate two fixed wing aircraft in support of this service.

We own a 25% interest in PAS, an Egyptian corporation which provides helicopter and fixed wing transportation to the offshore energy industry. Additionally, spare fixed wing capacity is chartered to tourism operators. PAS operates 41 helicopters and seven fixed wing aircraft from multiple locations. The remaining 75% interest in PAS is owned by the Egyptian General Petroleum Corporation.

Americas

As of March 31, 2018, we operated from three operating facilities in the U.S. Gulf of Mexico. We are one of the largest suppliers of industrial aviation services in the U.S. Gulf of Mexico. Our clients in this region are mostly independent and major integrated offshore energy companies. The U.S. Gulf of Mexico is a major offshore energy producing region. The shallow water platforms are typically unmanned and are serviced by small aircraft. The deepwater platforms are serviced by medium and large aircraft. Among our strengths in this region, in addition to our operating facilities, are our advanced flight-following systems and our widespread and strategically located offshore fuel stations. Operations in the U.S. Gulf of Mexico are subject to seasonality as the months of December through March typically have more days of harsh weather conditions than the other months of the year. Additionally, during the months of June through November, tropical storms and hurricanes may reduce activity as we are unable to operate in the area of the storm.

We also operate a SAR base at the South Lafourche Airport in Galliano, Louisiana. From this base, we have two medium and one large aircraft that provide SAR and/or medical evacuation services to oil and gas operators.

Additionally, we operate seven medium and one large aircraft in Trinidad from a base located at Trinidad’s Piarco International Airport and three medium aircraft in Guyana from a base located at Ogle International Airport. Our clients in Trinidad and Guyana are primarily engaged in offshore energy activities. We also provide rescue and recovery services for our clients in Trinidad and Guyana.

We own a 40% economic interest in Cougar Helicopters Inc. (“Cougar”), the largest offshore energy and SAR helicopter service provider in Atlantic Canada. Cougar has approximately 220 employees and its operations are primarily focused on serving the offshore oil and gas industry off Canada’s Atlantic coast. We leased eight large helicopters and four shore-based facilities to Cougar as of March 31, 2018, including state-of-the-art helicopter passenger, maintenance and SAR facilities located in Newfoundland and Labrador.

We also own a 41.9% economic interest in Líder, a provider of helicopter and corporate aviation services in Brazil. Líder has approximately 1,250 employees and operates through five primary operating units: helicopter service, maintenance, chartering, ground handling and aircraft sales, and provides commercial SAR and medical evacuation services to the oil and gas industry. Líder’s fleet includes 41 rotor wing and 20 fixed wing aircraft (including owned and managed aircraft). Líder also has a vast network of bases located strategically in Brazil. including locations in Macae, Rio de Janiero and Vitória, and is headquartered in Belo Horizonte, Brazil.

Asia Pacific

As of March 31, 2018, we operated in Australia from three bases located in Western Australia, one base in Victoria and one base in Northern Territory. Our operating bases are located in the vicinity of the major offshore energy exploration and production fields in the North West Shelf, the Browse and Carnarvon basins of Western Australia and the Bass Straits in Victoria. Our clients in Australia are primarily major integrated offshore energy companies. Additionally, we provide SAR and medical evacuation services to the oil and gas industry in Australia and engineering support to the Republic of Singapore Air Force’s fleet of helicopters at their base in Oakey, Queensland. Operations in the Asia Pacific region during the months of November through April may be impacted by cyclones that may reduce activity as we are unable to operate in the area of the storm.

8

Bristow Helicopters Australia owns a 100% interest in Airnorth, a regional fixed wing operator based in Darwin, North Territory, Australia. Airnorth has approximately 250 employees and its operations focus on providing both charter and scheduled services targeting the energy and mining industries in Northern and Western Australia as well as international services to Dili, Timor-Leste. Airnorth operates 14 fixed wing aircraft. We believe this investment strengthens our ability to provide point to point transportation services for existing Australian based passengers, expand industrial aviation services in certain areas in Southeast Asian markets and create a more integrated logistics solution for global clients.

Additionally, we operate seven large aircraft in Russia from three locations on Sakhalin Island, where we provide industrial aviation services to international and domestic offshore energy companies and operate a local SAR service.

Clients and Contracts

Our principal clients are major integrated, national and independent offshore energy companies and the U.K. Department for Transport. The following table presents our top ten clients in fiscal year 2018 and their percentage contribution to our consolidated gross revenue during fiscal years 2018, 2017 and 2016 and includes any clients accounting for 10% or more of our consolidated gross revenue during such fiscal years.

_______________

⁽¹⁾ IAC is the Integrated Aviation Consortium in the U.K. North Sea and comprises three major oil companies: BP, CNR International, EnQuest and TAQA.

⁽²⁾  As discussed above, we own a 40% economic interest in Cougar.

Our helicopter contracts are generally based on a two-tier rate structure consisting of a daily or monthly fixed fee plus additional fees for each hour flown. We also provide services to clients on an “ad hoc” basis, which usually entails a shorter notice period and shorter contract duration. Our charges for ad hoc services are generally based on an hourly rate, or a daily or monthly fixed fee plus additional fees for each hour flown. Generally, our ad hoc services have a higher margin than our other helicopter contracts due to supply and demand dynamics.

Generally, our oil and gas helicopter contracts are cancelable by the client with a notice period ranging from 30 to 180 days and in some cases up to one year. In the Americas region, we generally enter into short-term contracts for twelve months or less. Outside of the Americas, contracts are typically between two and five years in term. These long term contracts may also include escalation provisions allowing annual rate increases, which may be based on a fixed dollar or percentage increase, an increase in an agreed index or our actual substantiated increased costs, which we negotiate to pass along to clients. Cost reimbursements from clients are recorded as reimbursable revenue with the related reimbursed cost recorded as reimbursable expense in our consolidated statements of operations.

Generally, SAR services contracts include a monthly standing charge, which average approximately 85% of the total contract revenue, and a monthly variable charge that covers flying, fuel and ancillary items, which average approximately 15% of the total contract revenue. See further details on the U.K. SAR contract in “— Region Operations — Europe Caspian.”

Our fixed wing services are generally provided through scheduled charter service or regular public transport service. For scheduled charter service, our contracts typically include variable rates based on the number of passengers, flights or flight hours. These agreements may also include a monthly standing charge; however, this is much less common as compared to helicopter contracts. We also provide charter services to clients on an “ad hoc” basis, which usually entails a shorter notice period and shorter contract duration. Regular public transport service is provided through established daily or weekly flight schedules and is based upon individual ticket sales to customers.

Competition

The helicopter and fixed wing businesses are highly competitive throughout the world. We compete directly against multiple providers in almost all of our operating regions. We have several significant competitors in the North Sea, Nigeria, the U.S. Gulf of Mexico and Australia, and a number of smaller local competitors in other markets. Globally, we have seen a recent increase in competitive pressure and new regulation that could impact our ability to win future work. Competition has intensified and new competitors could enter our industry if they are willing to make a significant capital investment, have access to working capital, onshore and offshore bases, personnel and operating experience. These requirements can be achieved with the appropriate level of client support and commitment. In addition, while not the predominant practice, certain of our clients and potential clients in the offshore energy industry perform their own industrial aviation services.

In most situations, clients charter aircraft on the basis of competitive bidding. On limited occasions, our clients renew or extend existing contracts without employing a competitive bid process. Contracts are generally awarded based on a number of factors, including price, quality of service, operational experience, record of safety, quality and type of equipment, client relationship and professional reputation. Incumbent operators typically have a competitive advantage in the bidding process based on their relationship with the client, knowledge of the site characteristics and existing facilities to support the operations. Because certain of our clients in the offshore energy industry have the capability to perform their own industrial aviation services, our ability to increase charter rates may be limited under certain circumstances.

Code of Business Integrity

We have adopted a Code of Business Integrity (our “Code”) that applies to Bristow Group Inc. and all of its subsidiaries, affiliates and controlled joint ventures, including all directors, officers (including our principal executive officer, principal financial officer and principal accounting officer) and employees thereof. Our Code covers topics including, but not limited to, anti-corruption, conflicts of interest, insider trading, competition and fair dealing, discrimination and harassment, confidentiality, compliance procedures and employee complaint procedures. Our Code is posted on our website, http://www.bristowgroup.com, under the “About Us” and “Vision, Mission, Values” caption. We will disclose any amendment to the Code or waiver with respect to our senior officers on our website or, alternatively, through the filing of a Form 8-K.

Safety, Industry Hazards and Insurance

Hazards such as severe weather and mechanical failures are inherent in the transportation industry and may result in the loss of equipment and revenue. It is possible that personal injuries and fatalities may occur. We believe our air accident rate per 100,000 flight hours, which has historically been lower than the reported global offshore energy production helicopter average data, indicates that we have consistently performed better than the industry average with respect to safety. In fiscal year 2016, one Sikorsky S-76C+ and one Sikorsky S-76C++ aircraft operated by us were involved in accidents. In one of these accidents, two of our crew members and four passengers were fatally injured. The second accident resulted in no significant injuries or fatalities. During fiscal years 2018 and 2017, we had no accidents that resulted in fatalities.

Our well-established global safety program called “Target Zero” focuses on improved safety performance. Our safety vision is to have zero accidents, zero harm to people, and zero harm to the environment. The key components to achieving this are to improve safety culture and individual behaviors, increase the level of safety reporting by the frontline employees, increase accountability for addressing identified hazards by the operational managers and provide for independent oversight of the operational safety programs.

We maintain hull and liability insurance which generally insures us against damage to our aircraft and the related liabilities which may be incurred as a result. We also carry insurance for war risk, expropriation and confiscation of the aircraft we use in certain of our international operations. Further, we carry various other liability and property insurance, including workers’ compensation, general liability, employers’ liability, auto liability, and property and casualty coverage. We believe that our insurance program is adequate to cover any claims ultimately incurred related to property damage and liability events.

Employees

As of March 31, 2018, we employed 4,058 employees. Many of our employees are represented under collective bargaining agreements. Periodically, certain groups of our employees who are not covered by a collective bargaining agreement consider entering into such an agreement. We believe that our relations with our employees are generally satisfactory.

The following table sets forth our main employee groups and status of the collective bargaining agreements:

Governmental Regulation

United States

As a commercial operator of aircraft, our U.S. operations are subject to regulations under the Federal Aviation Act of 1958, as amended (the “Federal Aviation Act”), and other laws. We carry persons and property in our helicopters under an Air Taxi Certificate granted by the U.S. Federal Aviation Administration (the “FAA”). The FAA regulates our U.S. flight operations and, in this respect, exercises jurisdiction over personnel, aircraft, ground facilities and certain technical aspects of our operations. The National Transportation Safety Board is authorized to investigate aircraft accidents and to recommend improved safety standards. Our U.S. operations are also subject to the Federal Communications Act of 1934 because we use radio facilities in our operations.

Under the Federal Aviation Act, it is unlawful to operate certain aircraft for hire within the U.S. unless such aircraft are registered with the FAA and the FAA has issued an operating certificate to the operator. As a general rule, aircraft may be registered under the Federal Aviation Act only if the aircraft are owned or controlled by one or more citizens of the U.S. and an operating certificate may be granted only to a citizen of the U.S. For purposes of these requirements, a corporation is deemed to be a citizen of the U.S. only if at least 75% of its voting interests are owned or controlled by U.S. citizens, the president of the company is a U.S. citizen, two-thirds or more of the directors are U.S. citizens and the company is under the actual control of U.S. citizens. If persons other than U.S. citizens should come to own or control more than 25% of our voting interest or if any of the other requirements are not met, we have been advised that our aircraft may be subject to deregistration under the Federal Aviation Act, and we may lose our ability to operate within the U.S. Deregistration of our aircraft for any reason, including foreign ownership in excess of permitted levels, would have a material adverse effect on our ability to conduct certain operations within our Americas region operations. Therefore, our organizational documents currently provide for the automatic suspension of voting rights of shares of our outstanding voting capital stock owned or controlled by non-U.S. citizens, and our right to redeem those shares, to the extent necessary to comply with these requirements. As of March 31, 2018, approximately 6,214,000 shares of our common stock were held of record by persons with foreign addresses. These shares represented approximately 17% of our total outstanding common stock as of March 31, 2018. Our foreign ownership may fluctuate on each trading day because our common stock is publicly traded.

We are subject to the U.S. Foreign Corrupt Practices Act of 1977 (the “FCPA”), which generally prohibits us and our intermediaries from making corrupt payments to foreign officials for the purpose of obtaining or keeping business.

We are subject to regulations imposed by the U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”) and other U.S. laws and regulations that prohibit dealings with sanctioned countries and certain other third parties.

We are also subject to the International Traffic in Arms Regulations (“ITAR”) that control the export and import of defense-related articles, services and technical data. ITAR dictates that information and material pertaining to defense and military related technologies may only be shared with U.S. persons or organizations unless authorization from the U.S. State Department is received or a special exemption is used. We are also subject to the Export Administration Regulations (the “EAR”) that control the export of commercial and “dual use” goods. Persons or organizations subject to U.S. jurisdiction may incur heavy fines if they violate ITAR or the EAR.

United Kingdom

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 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. nationals, and must at all times be effectively controlled by them. To comply with these restrictions, we own only 49% of the ordinary shares of Bristow Aviation, the entity that owns Bristow Helicopters. In addition, we have a put/call agreement with the other two stockholders of Bristow Aviation which grants us the right to buy all of their Bristow Aviation ordinary shares (and grants them the right to require us to buy all of their shares). Under English law, to maintain Bristow Helicopters’ operating license, we would be required to find a qualified E.U. owner to acquire any of the Bristow Aviation shares that we have the right or obligation to acquire under the put/call agreement. In addition to our equity investment in Bristow Aviation, we own deferred stock, essentially a subordinated class of stock with no voting rights, and hold subordinated debt issued by Bristow Aviation.

12

The CAA regulates our U.K. flight operations and exercises jurisdiction over personnel, aircraft, ground facilities and certain technical aspects of those operations. The CAA often imposes improved safety standards. Under the Licensing of Air Carriers Regulations 1992, it is unlawful to operate certain aircraft for hire within the U.K. unless such aircraft are approved by the CAA. Changes in U.K. or E.U. statutes or regulations, administrative requirements or their interpretation may have a material adverse effect on our business or financial condition or on our ability to continue operations in the U.K.

Also, we are subject to the U.K. Bribery Act 2010 (the “U.K. Bribery Act”), which creates criminal offenses for bribery and failing to prevent bribery. We are also subject to new U.K. corporate criminal offenses for failure to prevent the facilitation of tax evasion pursuant to the Criminal Finances Act 2017, which imposes criminal liability on a company where it has failed to prevent the criminal facilitation of tax evasion by a person associated with the company.

Additionally, we are obligated to comply with U.K. and E.U. Export Controls and Economic Sanctions. U.K. and E.U. regulations may prevent the export of certain controlled items to certain controlled persons or destinations. In some circumstances, export authorizations may be available in respect of such exports. A variety of penalties, both criminal and civil, may be imposed for breaches of these regulations.

Nigeria

Our operations in Nigeria are subject to the Nigerian Content Development Act 2010, which requires that oil and gas contracts be awarded to a company that is seen or perceived to have more “local content” than a “Foreign” competitor. Additionally, the Nigerian Content Development Act allows the monitoring board to penalize companies that do not meet these local content requirements up to 5% of the value of the contract.

Other

Our operations in other markets are subject to local governmental regulations that may limit foreign ownership of aviation companies. Because of these local regulations, we conduct some of our operations through entities in which citizens of such countries own a majority interest and we hold a noncontrolling interest, or under contracts which provide that we operate assets for the local companies and conduct their flight operations. Such contracts are used for our operations in Russia and Turkmenistan. Changes in local laws, regulations or administrative requirements or their interpretation may have a material adverse effect on our business or financial condition or on our ability to continue operations in these areas.

Environmental

Our operations are subject to laws and regulations controlling the discharge of materials into the environment or otherwise relating to the protection of the environment. If we fail to comply with these environmental laws and regulations, administrative, civil and criminal penalties may be imposed, and we may become subject to regulatory enforcement actions in the form of injunctions and cease and desist orders. We may also be subject to civil claims arising out of a pollution event. These laws and regulations may expose us to strict, joint and several liability for the conduct of or conditions caused by others or for our own acts even though these actions were in compliance with all applicable laws at the time they were performed. To date, such laws and regulations have not had a material adverse effect on our business, results of operations or financial condition.

Increased public awareness and concern over the environment may result in future changes in the regulation of the offshore energy industry, which in turn could adversely affect us. The trend in environmental regulation is to place more restrictions and limitations on activities that may affect the environment and there can be no assurance as to the effect of such regulation on our operations or on the operations of our clients. We try to anticipate future regulatory requirements that might be imposed and plan accordingly to remain in compliance with changing environmental laws and regulations and to minimize the cost of such compliance. We do not believe that compliance with federal, state or local environmental laws and regulations will have a material adverse effect on our business, financial position or results of operations. We cannot be certain that future events, such as changes in existing laws, the promulgation of new laws, or the development or discovery of new facts or conditions will not cause us to incur significant costs. Below is a discussion of the material U.S. environmental laws and regulations that relate to our business. We believe that we are in substantial compliance with all of these environmental laws and regulations.

13

Under the Comprehensive Environmental Response, Compensation and Liability Act, referred to as CERCLA or the Superfund law, and related state laws and regulations, strict, joint and several liability can be imposed without regard to fault or the legality of the original conduct on certain classes of persons that contributed to the release of a hazardous substance into the environment. These persons include the owner and operator of a contaminated site where a hazardous substance release occurred and any company that transported, disposed of or arranged for the transport or disposal of hazardous substances, even from inactive operations or closed facilities that have been released into the environment. In addition, neighboring landowners or other third parties may file claims for personal injury, property damage and recovery of response cost. We currently own, lease, or operate properties and facilities that, in some cases, have been used for industrial activities for many years. Hazardous substances, wastes, or hydrocarbons may have been released on or under the properties owned or leased by us, or on or under other locations where such substances have been taken for disposal. In addition, some of these properties have been operated by third parties or by previous owners whose treatment and disposal or release of hazardous substances, wastes, or hydrocarbons was not under our control. These properties and the substances disposed or released on them may be subject to CERCLA and analogous state statutes. Under such laws, we could be required to remove previously disposed substances and wastes, remediate contaminated property, or perform remedial activities to prevent future contamination. These laws and regulations may also expose us to liability for our acts that were in compliance with applicable laws at the time the acts were performed. We have been named as a potentially responsible party in connection with certain sites. See further discussion under Item 3. “Legal Proceedings” included elsewhere in this Annual Report.

In addition, since our operations generate wastes, including some hazardous wastes, we may be subject to the provisions of the Resource, Conservation and Recovery Act (“RCRA”) and analogous state laws that limit the approved methods of disposal for some types of hazardous and nonhazardous wastes and require owners and operators of facilities that treat, store or dispose of hazardous waste and to clean up releases of hazardous waste constituents into the environment associated with their operations. Some wastes handled by us that currently are exempt from treatment as hazardous wastes may in the future be designated as “hazardous wastes” under RCRA or other applicable statutes. If this were to occur, we would become subject to more rigorous and costly operating and disposal requirements.

The Federal Water Pollution Control Act, also known as the Clean Water Act, and analogous state laws impose restrictions and strict controls regarding the discharge of pollutants into state waters or waters of the U.S. The discharge of pollutants into jurisdictional waters is prohibited unless the discharge is permitted by the U.S. Environmental Protection Agency (“EPA”) or applicable state agencies. Some of our properties and operations require permits for discharges of wastewater and/or stormwater, and we have a system in place for securing and maintaining these permits. In addition, the Oil Pollution Act of 1990 imposes a variety of requirements on responsible parties related to the prevention of oil spills and liability for damages, including natural resource damages, resulting from such spills in the waters of the U.S. A responsible party includes the owner or operator of a facility. The Clean Water Act and analogous state laws provide for administrative, civil and criminal penalties for unauthorized discharges and, together with the Oil Pollution Act, impose rigorous requirements for spill prevention and response planning, as well as substantial potential liability for the cost of removal, remediation, and damages in connection with any unauthorized discharges.

Some of our operations also result in emissions of regulated air pollutants. The Federal Clean Air Act and analogous state laws require permits for facilities that have the potential to emit substances into the atmosphere that could adversely affect environmental quality. Failure to obtain a permit or to comply with permit requirements could result in the imposition of substantial administrative, civil and even criminal penalties.

Our facilities and operations are also governed by laws and regulations relating to worker health and workplace safety, including the Federal Occupational Safety and Health Act, or OSHA. We believe that appropriate precautions are taken to protect our employees and others from harmful exposure to potentially hazardous materials handled and managed at our facilities, and that we operate in substantial compliance with all OSHA or similar regulations.

In addition, we could be affected by future laws or regulations imposed in response to concerns over climate change. Changes in climate change concerns, or in the regulation of such concerns, including greenhouse gas emissions, could subject us to additional costs and restrictions, including compliance costs and increased energy and raw materials costs.

Our operations outside of the U.S. are subject to similar foreign governmental controls relating to protection of the environment. We believe that, to date, our operations outside of the U.S. have been in substantial compliance with existing requirements of these foreign governmental bodies and that such compliance has not had a material adverse effect on our operations. There is no assurance, however, that future expenditures to maintain compliance will not become material.

Item 1A. Risk Factors

If you hold our securities or are considering an investment in our securities, you should carefully consider the following risks, together with the other information contained in this Annual Report.

Risks Relating to Our Clients and Contracts

The demand for our services is substantially dependent on the level of offshore oil and gas exploration, development and production activity.

We provide helicopter and fixed wing services to companies engaged in offshore oil and gas exploration, development and production activities. As a result, demand for our services, as well as our revenue and our profitability, are substantially dependent on the worldwide levels of activity in offshore oil and gas exploration, development and production. These activity levels are principally affected by trends in, and expectations regarding, oil and natural gas prices, as well as the capital expenditure budgets of offshore energy companies. We cannot predict future exploration, development and production activity or oil and gas price movements. Historically, the prices for oil and gas and activity levels have been volatile and are subject to factors beyond our control, such as:

• the supply of and demand for oil and gas and market expectations for such supply and demand;

• actions of the Organization of Petroleum Exporting Countries and other oil producing countries to control prices or change production levels;

• general economic conditions, both worldwide and in particular regions;

• governmental regulation;

• the price and availability of alternative fuels;

• weather conditions, including the impact of hurricanes and other weather-related phenomena;

• advances in exploration, development and production technology;

• the policies of various governments regarding exploration and development of their oil and gas reserves; and

• the worldwide political environment, including uncertainty or instability resulting from an escalation or additional outbreak of armed hostilities or other crises in the Middle East, Nigeria or other geographic areas, or further acts of terrorism in the U.K., U.S. or elsewhere.

Additionally, an increase in onshore fracking, which generally does not require use of our services, could have an adverse effect on our operations. If onshore fracking were to meaningfully increase globally, and if it were to drive a meaningful increase in the supply of hydrocarbons without an increase in global demand, it could potentially adversely impact oil and natural gas prices and the level of activity in our offshore oil and gas markets and the demand for our industrial aviation services.

A focus by our clients on cost-saving measures rather than quality of service, which is how we differentiate ourselves from competition, could reduce the demand for our services.

Historically, we had the ability to secure profitable contracts by providing superior quality as compared to our competitors. However, offshore energy companies are continually seeking to implement measures aimed at greater cost savings, including efforts to accept lesser quality services, otherwise improve cost efficiencies with respect to air transportation services, or to provide other alternatives for transportation, such as boats. For example, these companies may reduce staffing levels on both old and new installations by using new technology to permit unmanned installations, may reduce the frequency of transportation of employees by increasing the length of shifts offshore, may change other aspects of how our services are scheduled and may consider other alternatives to our services to achieve cost savings. In addition, these companies could initiate their own helicopter, airplane or other transportation alternatives. The continued implementation of these kinds of measures could reduce the demand or pricing for our services and have a material adverse effect on our business, financial condition and results of operations.

15

Our industry is highly competitive and cyclical, with intense price competition.

The helicopter and fixed wing businesses are highly competitive throughout the world. Chartering of such aircraft is often done on the basis of competitive bidding among those providers having the necessary equipment, operational experience and resources. Factors that affect competition in our industry include price, quality of service, operational experience, record of safety, quality and type of equipment, client relationship and professional reputation.

Our industry has historically been cyclical and is affected by the volatility of oil and gas price levels. There have been periods of high demand for our services, followed by periods of low demand for our services. Changes in commodity prices can have a significant effect on demand for our services, and periods of low activity intensify price competition in the industry and often result in our aircraft being idle for long periods of time.

We have several significant competitors in the North Sea, Nigeria, the U.S. Gulf of Mexico, Australia, Canada and Brazil, and a number of smaller local competitors in other markets. Certain of our clients have the capability to perform their own air transportation operations or give business to our competitors should they elect to do so, which has a limiting effect on our rates.

As a result of significant competition, we must continue to provide safe and efficient service and we must continue to evolve our technology or we will lose market share, which could have a material adverse effect on our business, financial condition and results of operations due to the loss of a significant number of our clients or termination of a significant number of our contracts. See further discussion in Item 1. “Business — Competition” included elsewhere in this Annual Report.

We depend on a small number of large offshore energy industry clients for a significant portion of our revenue.

We derive a significant amount of our revenue from a small number of offshore energy companies. Our loss of one of these significant clients, if not offset by sales to new or other existing clients, could have a material adverse effect on our business, financial condition and results of operations. See further discussion in Item 1. “Business — Clients and Contracts” included elsewhere in this Annual Report.

Our contracts often can be terminated or downsized by our clients without penalty.

Many of our fixed-term contracts contain provisions permitting early termination by the client at their convenience, generally without penalty, and with limited notice requirements. In addition, many of our contracts permit our clients to decrease the number of aircraft under contract with a corresponding decrease in the fixed monthly payments without penalty. As a result, you should not place undue reliance on the strength of our client contracts or the terms of those contracts.

Our U.K. SAR contract can be terminated and is subject to certain other rights of the DfT.

The U.K. SAR contract allows the DfT to cancel the contract for any reason upon notice and payment of a specified cancellation fee based on the number of bases reduced as a result of the exercise and the timing of the exercise. Additionally, the U.K. SAR contract grants the DfT the option to require us to transfer to the DfT, at termination or expiration, either the lease or the ownership of some or all of the helicopters that service the U.K. SAR contract. The DfT may alternatively require that we or the owner, as the case may be, transfer the lease or ownership of the helicopters to any replacement service provider. If the DfT wishes to transfer ownership it must pay a specified option exercise fee based on the value of the helicopters.  If the DfT wishes to transfer the lease it does not have to pay an option exercise fee. We currently lease the majority of the aircraft that service the U.K. SAR contract. Although we are entitled to some compensation for termination or early expiration if we are not at fault, termination or early expiration of the U.K. SAR contract would result in a significant loss of expected revenue. Additionally, we do not have the right to transfer the ground facilities supporting the U.K. SAR contract to the replacement service provider. If alternative long-term uses were not identified for these facilities, we could incur recurring fixed expenses for these recently acquired, non-revenue producing assets if we were unable to sell them to a replacement contractor or other party in the event the U.K. SAR contract is terminated.

Our clients may shift risk to us.

We give to and receive from our clients indemnities relating to damages caused or sustained by us in connection with our operations. Our clients’ changing views on risk allocation together with deteriorating market conditions could force us to accept greater risk to win new business, retain renewing business or could result in us losing business if we are not prepared to take such risks. To the extent that we accept such additional risk, and seek to insure against it, if possible, our insurance premiums could rise. If we cannot insure against such risks or otherwise choose not to do so, we could be exposed to catastrophic losses in the event such risks are realized.

16

We may not be able to obtain client contracts with acceptable terms covering some of our new helicopters, and some of our new helicopters may replace existing helicopters already under contract, which could adversely affect the utilization of our existing fleet.

We have ordered, and have options for, a substantial number of new helicopters. Many of our new helicopters may not be covered by client contracts when they are delivered to us, and we cannot assure you as to when we will be able to utilize these new helicopters or on what terms. To the extent our helicopters are covered by a client contract when they are delivered to us, some of these contracts may be for a short term, requiring us to seek renewals more frequently. Alternatively, we expect that some of our clients may request new helicopters in lieu of our existing helicopters, which could adversely affect the utilization of our existing fleet.

Reductions in spending on industrial aviation services by government agencies could lead to modifications of SAR contract terms or delays in receiving payments, which could adversely impact our business, financial condition and results of operations.

Any reductions in the budgets of government agencies for spending on industrial aviation services, implementation of cost saving measures by government agencies, including the DfT, imposed modifications of contract terms or delays in collecting receivables owed to us by our government agency clients could have an adverse effect on our business, financial condition and results of operations.

In addition, there are inherent risks in contracting with government agencies. Applicable laws and regulations in the countries in which we operate may enable our government agency clients to (i) terminate contracts for convenience, (ii) reduce, modify or cancel contracts or subcontracts if requirements or budgetary constraints change, or (iii) terminate contracts or adjust their terms.

Our fixed operating expenses and long-term contracts with clients could adversely affect our business under certain circumstances.

Our profitability is directly related to demand for our services. Because of the significant expenses related to aircraft financing and leasing, crew wages and benefits, and insurance and maintenance programs, a substantial portion of our operating expenses are fixed and must be paid even when aircraft are not actively servicing clients and thereby generating revenue. A decrease in our revenue could therefore result in a disproportionate decrease in our earnings, as a substantial portion of our operating expense would remain unchanged. Similarly, the discontinuation of any rebates, discounts or preferential financing terms offered to us by manufacturers, lenders or lessors could have the effect of increasing our related expenses, and without a corresponding increase in our revenue, could negatively impact our results of operations.

Certain of our long-term aircraft services contracts contain price escalation terms and conditions. Although supplier costs, fuel costs, labor costs, insurance costs, and other cost increases are typically passed through to our clients through rate increases where possible, these escalations may not be sufficient to enable us to recoup increased costs in full and we may not be able to realize the full benefit of contract price escalations during a market downturn. There can be no assurance that we will be able to estimate costs accurately or recover increased costs by passing these costs on to our clients. We may not be successful in identifying or securing cost escalations for other costs that may escalate during the applicable client contract term. In the event that we are unable to fully recover material costs that escalate during the terms of our client contracts, the profitability of our client contracts and our business, financial condition and results of operations could be materially and negatively affected.

Additionally, cost increases related to our airline scheduled service cannot be passed on to previously purchased air passenger tickets but may be passed on partially or wholly to future purchased tickets if the rates remain competitive to other competing airlines.

17

Risks Relating to Our Business

In order to support our business, we may require additional capital in the future that may not be available to us.

Our business is capital intensive, and to the extent we do not generate sufficient cash from operations, we will need to raise additional funds through bank debt, public or private debt, or equity financings to execute our growth strategy and to fund operating losses. Adequate sources of capital funding may not be available when needed, or may not be available on favorable terms. If we raise additional funds by issuing equity or certain types of convertible debt securities, dilution to the holdings of existing stockholders may result. Further, if we raise additional debt financing, we will incur additional interest expense and the terms of such debt may be at less favorable rates than existing debt and could require the pledge of additional assets as security or subject us to financial and/or operating covenants that affect our ability to conduct our business. If funding is insufficient at any time in the future, we may be unable to acquire additional aircraft, take advantage of business opportunities, fund operating losses or respond to competitive pressures, any of which could harm our business, financial condition and results of operations. See discussion of our capital commitments in Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Future Cash Requirements” included elsewhere in this Annual Report.

The vote by the United Kingdom to leave the E.U. could adversely affect us.

In a referendum held on June 23, 2016, voters in the U.K. approved Brexit. 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 starts a two-year time period for the U.K. and the remaining E.U. Member States to negotiate a withdrawal agreement.

For fiscal years 2018, 2017 and 2016, approximately 37%, 36% and 34%, respectively, of our revenue was derived from contracts with customers in the U.K., and for fiscal years 2018, 2017 and 2016, approximately 18%, 16% and 16%, respectively, of our revenue was derived from contracts with customers in other European markets.

The consequences of Brexit, together with the protracted negotiations around the terms of Brexit, could introduce significant uncertainties into global financial markets and adversely impact the regions in which we and our clients operate. In the long term, Brexit could also 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 divergent national laws and regulations as the U.K. government determines which E.U. laws to modify or replace. Brexit also exacerbates the potential for additional referendums within the U.K., such as in Scotland, which could lead to a breakup of the U.K, creating further legal and regulatory uncertainty.

The Brexit vote initially resulted in a significant decline in the value of British pound sterling. While the British pound sterling has since partially recovered as negotiations over the terms of Brexit have progressed, volatility in exchange rates remains possible. If the British pound sterling weakens once again, revenue under contracts denominated in British pound sterling will translate into fewer U.S. dollars. For fiscal years 2018 and 2017, revenue denominated in British pound sterling represented 35% and 34% of our revenue, respectively. The uncertainties surrounding Brexit and risks associated with the commencement of Brexit could have a material adverse effect on our current business and future growth.

We may undertake one or more significant corporate transactions that may not achieve their intended results, may adversely affect our financial condition and our results of operations or result in unforeseeable risks to our business.

We continuously evaluate the acquisition or disposition of operating businesses and assets and may in the future undertake one or more significant transactions. Any such transaction could be material to our business and could take any number of forms, including mergers, joint ventures and the purchase of equity interests. The consideration for such acquisitive transactions may include, among other things, cash, common stock or equity interests in us or our subsidiaries, or a contribution of equipment to obtain equity interests, and in conjunction with a transaction we might incur additional indebtedness. We also routinely evaluate the benefits of disposing of certain of our assets.

These transactions may present significant risks such as insufficient revenue to offset liabilities assumed, potential loss of significant revenue and income streams, increased or unexpected expenses, inadequate return of capital, regulatory or compliance issues, the triggering of certain covenants in our debt agreements (including accelerated repayment) and unidentified issues not discovered in due diligence. In addition, such transactions could distract management from current operations. As a result of the risks inherent in such transactions, we cannot guarantee that any such transaction will ultimately result in the realization of its anticipated benefits or that it will not have a material adverse effect on our business, financial condition and results of operations. If we were to complete such an acquisition, disposition, investment or other strategic transaction, we may require additional debt or equity financing that could result in a significant increase in our amount of debt and our debt service obligations or the number of outstanding shares of our common stock, thereby diluting holders of our common stock outstanding prior to such acquisition.

18

Our operations involve a degree of inherent risk that may not be covered by our insurance and may increase our operating costs.

The operation of helicopters and fixed wing aircraft inherently involves a degree of risk. Hazards such as harsh weather and marine conditions, mechanical failures, facility fires and spare parts damage, pandemic outbreaks, crashes and collisions are inherent in our business and may result in personal injury, loss of life, damage to property and equipment, suspension or reduction of operations, reduced number of flight hours and the grounding of such aircraft or insufficient ground facilities or spare parts to support operations. In addition to any loss of property or life, our revenue, profitability and margins could be materially affected by an accident or asset damage.

We, or third parties operating our aircraft, may experience accidents or damage to our assets in the future. These risks could endanger the safety of both our own and our clients’ personnel, equipment, cargo and other property, as well as the environment. If any of these events were to occur with equipment or other assets that we need to operate or lease to third parties, we could experience loss of revenue, termination of charter contracts, higher insurance rates, and damage to our reputation and client relationships. In addition, to the extent an accident occurs with aircraft we operate or to assets supporting operations, we could be held liable for resulting damages. Even where losses or liability for damages is covered by insurance, we may incur deductibles and additional insurance premiums. The lack of sufficient insurance for an incident or accident could have a material adverse effect on our operations and financial condition.

Certain models of aircraft that we operate have also experienced accidents while operated by third parties. Most recently, on April 29, 2016, an incident occurred with an Airbus Helicopters EC225LP (also known as an H225) model helicopter operated by another helicopter company, which resulted in the loss of life for eleven passengers and two crew members in Norway. This incident resulted in the civil aviation authorities in the U.K. and Norway issuing safety directives that required the operators to suspend commercial operations of the affected aircraft pending determination of the root cause. Although the civil aviation authorities have since issued a safety directive providing for return to service, our H225 fleet of 24 aircraft remains grounded globally as a result of this incident. If other operators experience accidents with aircraft models that we operate or lease, obligating us to take such aircraft out of service until the cause of the accident is rectified, we could lose revenue and clients. In addition, safety issues experienced by a particular model of aircraft could result in clients refusing to use that particular aircraft model or a regulatory body grounding that particular aircraft model. The value of the aircraft model might also be permanently reduced in the market if the model were to be considered less desirable for future service and the inventory for such aircraft may be impaired.

We attempt to protect ourselves against financial losses and damage by carrying insurance, including hull and liability, general liability, workers’ compensation, and property and casualty insurance. Our insurance coverage is subject to deductibles and maximum coverage amounts, and we do not carry insurance against all types of losses, including business interruption. We cannot assure you that our existing coverage will be sufficient to protect against all losses, that we will be able to maintain our existing coverage in the future or that the premiums will not increase substantially. In addition, future terrorist activity, risks of war, accidents or other events could increase our insurance premiums. The loss of our liability insurance coverage, inadequate coverage from our liability insurance or substantial increases in future premiums could have a material adverse effect on our business, financial condition and results of operations.

Failure to maintain standards of acceptable safety performance may have an adverse impact on our ability to attract and retain clients and could adversely impact our reputation, operations and financial performance.

Our clients consider safety and reliability as two of the primary attributes when selecting a provider of air transportation services. If we fail to maintain standards of safety and reliability that are satisfactory to our clients, our ability to retain current clients and attract new clients may be adversely affected. Accidents or disasters could impact client or passenger confidence in a particular fleet type, us or the air transportation services industry as a whole and could lead to a reduction in client contracts, particularly if such accidents or disasters were due to a safety fault in a type of aircraft used in our fleet. In addition, the loss of aircraft as a result of accidents could cause significant adverse publicity and the interruption of air services to our clients, which could adversely impact our reputation, operations and financial results. Our aircraft have been involved in accidents in the past, some of which have included loss of life and property damage. We may experience similar accidents in the future.

19

Our diversification efforts into other industrial aviation services such as fixed wing, SAR, and unmanned aerial vehicle services may prove unsuccessful.

Our business has traditionally been significantly dependent upon the level of offshore oil and gas exploration, development and production activity. Although the company has begun diversification efforts with the award for the provision of SAR services in the U.K. and investments in Eastern Airways, Airnorth and Sky-Futures, the effect of the downturn in the oil and gas industry has nevertheless negatively impacted our financial results and could continue to negatively impact our financial results in future periods. While diversification into other industrial aviation services is intended over the long term to grow the business and offset the cyclical nature of the underlying oil and gas business, we cannot be certain that diversification benefits associated with those lines of business will be realized at any point.

Our operations in certain regions of the world are subject to additional risks.

Operations in certain regions are subject to various risks inherent in conducting business in international locations, including:

• political, social and economic instability, including risks of war, general strikes and civil disturbances;

• physical and economic retribution directed at U.S. and foreign companies and personnel;

• governmental actions that restrict payments or the movement of funds or result in the deprivation of contract rights;

• violations of our Code;

• adverse tax consequences;

• fluctuations in currency exchange rates, hard currency shortages and controls on currency exchange that affect demand for our services and our profitability;    

• potential noncompliance with a wide variety of laws and regulations, such as the FCPA, and similar non-U.S. laws and regulations, including the U.K. Bribery Act and Brazil’s Clean Companies Act (the “BCCA”);

• the taking of property without fair compensation; and

• the lack of well-developed legal systems in some countries that could make it difficult for us to enforce our contractual rights.

Historically, there has been continuing political and social unrest in Nigeria, where we derived 14%, 15% and 14% of our gross revenue during fiscal years 2018, 2017 and 2016, respectively. In 2015, there was a change in the leadership in Nigeria. The current leadership is facing numerous challenges which, if not addressed, may cause political or social unrest and result in a lack of demand for our services in Nigeria and safety risks for our operations and our people. Our operations in Nigeria are subject to the Nigerian Content Development Act 2010, which requires that oil and gas contracts be awarded to a company that is seen or perceived to have more “local content” than a “Foreign” competitor. Additionally, the Nigerian Content Development Act allows the monitoring board to penalize companies that do not meet these local content requirements up to 5% of the value of the contract. In addition, the passage of the Nigerian Petroleum Industry Bill could lead to further uncertainty in demand in the region. Future unrest or legislation in Nigeria or our other operating regions could adversely affect our business, financial condition and results of operations in those regions. We cannot predict whether any of these events will continue to occur in Nigeria or occur elsewhere in the future.

We also have a joint venture operating in Sakhalin that may be negatively impacted by any further changes to current sanctions against Russia.

20

We are highly dependent upon the level of activity in the North Sea and to a lesser extent the U.S. Gulf of Mexico, which are mature exploration and production regions.

In fiscal years 2018, 2017 and 2016, approximately 62%, 58% and 58%, respectively, of our gross revenue was derived from industrial aviation services provided to oil and gas clients operating in the North Sea and the U.S. Gulf of Mexico. The North Sea and the U.S. Gulf of Mexico are mature exploration and production regions that have undergone substantial seismic survey and exploration activity for many years. Because a large number of oil and gas properties in these regions have already been drilled, additional prospects of sufficient size and quality (including projected costs permitting economic development, given anticipated hydrocarbon prices) could be more difficult to identify. The ability of our clients to produce sufficient quantities to support the costs of exploration in different basins could impact the level of future activity in these regions. Generally, the production from these drilled oil and gas properties is declining. In the future, production may decline to the point that such properties are no longer economic to operate, in which case, our services with respect to such properties will no longer be needed. Oil and gas companies may not identify sufficient additional drilling sites to replace those that become depleted. In addition, the U.S. government’s exercise of authority under the Outer Continental Shelf Lands Act, as amended, to restrict the availability of offshore oil and gas leases together with the U.K. government’s exercise of authority could adversely impact exploration and production activity in the U.S. Gulf of Mexico and the U.K. North Sea, respectively.

If activity in oil and gas exploration, development and production in either the U.S. Gulf of Mexico or the North Sea materially declines, our business, financial condition and results of operations could be materially and adversely affected. We cannot predict the levels of activity in these areas.

We are exposed to credit risk.

We are exposed to credit risk on our financial investments, which depends on the ability of our counterparties to fulfill their obligations to us. We manage credit risk by entering into arrangements with established counterparties and through the establishment of credit policies and limits, which are applied in the selection of counterparties.

Credit risk on financial instruments arises from the potential for counterparties to default on their contractual obligations and is limited to those contracts on which we would incur a loss in replacing the instrument. We monitor our concentration risk with counterparties on an ongoing basis. The carrying amount of financial assets represents the maximum credit exposure for financial assets.

Credit risk arises on our trade receivables from the unexpected loss in cash and earnings when a client cannot meet its obligation to us or when the value of any security provided declines. To mitigate trade credit risk, we have developed credit policies that include the review, approval and monitoring of new clients, annual credit evaluations and credit limits. There can be no assurance that our risk mitigation strategies will be effective and that credit risk will not adversely affect our financial condition and results of operations.

In addition, the majority of our customers are engaged in oil and gas production, exploration and development. For fiscal year 2018, we generated approximately 68% of our consolidated operating revenue from external clients from oil and gas operations. This concentration could impact our overall exposure to credit risk because changes in economic and industry conditions that adversely affect the oil and gas industry could affect the credit worthiness of many of our customers. We generally do not require letters of credit or other collateral to support our trade receivables. Accordingly, a continued or additional downturn in the economic condition of the oil and gas industry could adversely impact our ability to collect our receivables and thus impact our business, financial condition and results of operations.

Our failure to dispose of aircraft through sales into the aftermarket could adversely affect us.

The management of our global aircraft fleet involves a careful evaluation of the expected demand for our services across global markets, including the type of aircraft needed to meet this demand. As offshore oil and gas drilling and production globally moves to deeper water, more medium and large aircraft and newer technology aircraft may be required. During a downturn in the oil and gas industry or as older aircraft models come off of current contracts and are replaced by new aircraft, our management evaluates our future needs for these aircraft models and ultimately the ability to recover our remaining investments in these aircraft through sales into the aftermarket. We depreciate our aircraft over their expected useful life to the expected salvage value to be received for the aircraft at the end of that life. However, depending on the market for aircraft, we may record gains or losses on aircraft sales. In certain instances where a cash return can be made on newer aircraft in excess of the expected return available through the provision of our services, we may sell newer aircraft. The number of aircraft sales and the amount of gains and losses recorded on these sales can be unpredictable. In May 2016, a global competitor filed for Chapter 11 bankruptcy protection and announced its intention to reject leases resulting in the return of approximately 90 leased helicopters to lessors. This significant return of aircraft into an already oversupplied market could undermine our ability to dispose of our aircraft and could have a material adverse effect on our business, financial condition and results of operations.

21

Changes in effective tax rates, taxation of our foreign subsidiaries or adverse outcomes resulting from examination of our tax returns could adversely affect our business, financial condition and results of operations.

Our future effective tax rates could be adversely affected by changes in tax laws, both domestically and internationally, or the interpretation or application thereof.  From time to time, the U.S. Congress and foreign, state and local governments consider legislation that could increase our effective tax rate or the effective tax rates of our consolidated affiliates. We cannot determine whether, or in what form, legislation will ultimately be enacted or what the impact of any such legislation could have on our profitability. If these or other changes to tax laws are enacted, our profitability could be negatively impacted.

Our future effective tax rates could also be adversely affected by changes in the valuation of our deferred tax assets and liabilities, changes in the mix of earnings in countries with differing statutory tax rates, the ultimate repatriation of earnings from foreign subsidiaries to the U.S., or by changes in tax treaties, regulations, accounting principles or interpretations thereof in one or more countries in which we operate. In addition, we are subject to the potential examination of our income tax returns by the Internal Revenue Service and other tax authorities where we file tax returns. We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. There can be no assurance that such examinations will not have a material adverse effect on our business, financial condition and results of operations.

If our goodwill, intangible assets or investments in unconsolidated affiliates become impaired we may be required to record a significant charge to earnings.

We acquire other companies and intangible assets, and make investments in unconsolidated affiliates, and may not realize all of the economic benefit from those acquisitions or investments, which could cause an impairment of goodwill, intangibles or investments in unconsolidated affiliates. We review our intangible assets for impairment when events or changes in circumstances indicate the carrying value may not be recoverable. We test goodwill for impairment at least annually. Factors that may be a change in circumstances, indicating that the carrying value of our goodwill, intangible assets or investments in unconsolidated affiliates may not be recoverable, include a decline in our stock price and market capitalization, reduced future cash flow estimates, and slower growth rates in the industry in which we operate. For example, in fiscal years 2017 and 2016, we recognized losses of $8.7 million and $49.7 million, respectively, associated with the impairment of goodwill and other intangibles as a result of the market downturn. In fiscal year 2018, we recorded an $85.7 million impairment to our investment in Líder in Brazil. We may be required to record significant additional charges in our consolidated financial statements during the period in which any impairment of our goodwill, intangible assets or investments in unconsolidated affiliates is determined, which could adversely affect our results of operations.

Foreign exchange risks and controls may affect our financial position and results of operations.

Through our operations outside the U.S., we are exposed to foreign currency fluctuations and exchange rate risks. As a result, a strong U.S. dollar may increase the local cost of our services that are provided under U.S. dollar-denominated contracts, which may reduce the demand for our services in foreign countries.

Because we maintain our financial statements in U.S. dollars, our financial results are vulnerable to fluctuations in the exchange rate between the U.S. dollar and foreign currencies, such as the British pound sterling, Australian dollar, euro, Norwegian kroner and Nigerian naira. In preparing our financial statements, we must convert all non-U.S. dollar results to U.S. dollars. The effect of foreign currency translation impacts our results of operations as a result of the translation of non-U.S. dollar results and is reflected as a component of stockholders’ investment, while the revaluation of certain monetary foreign currency transactions is credited or charged to income and reflected in other income (expense), net. Additionally, our earnings from unconsolidated affiliates, net of losses, are affected by the impact of changes in foreign currency exchange rates on the reported results of our unconsolidated affiliates, primarily the impact of changes in the Brazilian real and the U.S. dollar exchange rate on results for our affiliate in Brazil. Changes in exchange rates could cause significant changes in our financial position and results of operations in the future.

We operate in countries with foreign exchange controls including Brazil, Egypt, Nigeria, Russia and Turkmenistan. These controls may limit our ability to repatriate funds from our international operations and unconsolidated affiliates or otherwise convert local currencies into U.S. dollars. These limitations could adversely affect our ability to access cash from these operations.

See further discussion of foreign exchange risks and controls under Item 7A. “Quantitative and Qualitative Disclosures about Market Risk” included elsewhere in this Annual Report.

Our dependence on a small number of helicopter manufacturers and lessors poses a significant risk to our business and prospects, including when we seek to grow our business.

We contract with a small number of manufacturers and lessors for most of our aircraft expansion, replacement and leasing needs. If any of the manufacturers face production delays due to, for example, natural disasters, labor strikes or availability of skilled labor, we may experience a significant delay in the delivery of previously ordered aircraft. During these periods, we may not be able to obtain orders for additional aircraft with acceptable pricing, delivery dates or other terms. Also, we have operating leases for many of our helicopters. The number of companies that provide leasing for helicopters is limited. If any of these leasing companies face financial setbacks, we may experience delays or restrictions in our ability to lease aircraft. Delivery delays or our inability to obtain acceptable aircraft orders or lease aircraft could adversely affect our revenue and profitability and could jeopardize our ability to meet the demands of our clients and grow our business. For example, our efforts to successfully integrate AW189 aircraft into service for the U.K. SAR contract have been delayed due to a product improvement plan with the aircraft. As a result, the acceptance of four AW189 aircraft was pushed to later dates. We continue to meet our contractual obligations under the U.K. SAR contract through the utilization of other aircraft. Additionally, lack of availability of new aircraft resulting from a backlog in orders could result in an increase in prices for certain types of new and used helicopters.

If any of the helicopter manufacturers we contract with, the government bodies that regulate them or other parties identify safety issues with helicopter models we currently operate or that we intend to acquire, we may be required to suspend flight operations, as was done with the H225 aircraft. If we are forced to suspend operations of helicopter models, our business, financial condition and results of operations during any period in which flight operations are suspended could be affected.

A shortfall in availability of aircraft components and parts required for maintenance and repairs of our helicopter and fixed wing aircraft and supplier cost increases could adversely affect us.

In connection with the required maintenance and repairs performed on our aircraft in order for them to stay fully operational and available for use in our operations, we rely on a few key vendors for the supply and overhaul of components fitted to our aircraft. These vendors have historically worked at or near full capacity supporting the aircraft production lines and the maintenance requirements of various government and civilian aircraft operators that may also operate at or near capacity in certain industries, including operators such as us who support the energy industry. Such conditions can result in backlogs in manufacturing schedules and some parts being in limited supply from time to time, which could have an adverse impact upon our ability to maintain and repair our aircraft. To the extent that these suppliers also supply parts for aircraft used by governments in military operations, parts delivery for our aircraft may be delayed. Our inability to perform timely maintenance and repairs can result in our aircraft being underutilized, which could have an adverse impact on our operating results and financial condition. Furthermore, our operations in remote locations, where delivery of these components and parts could take a significant period of time, may also impact our ability to maintain and repair our aircraft. While every effort is made to mitigate such impact, this may pose a risk to our operating results. Additionally, supplier cost increases for critical aircraft components and parts also pose a risk to our operating results. Cost increases for contracted services are passed through to our clients through rate increases where possible, including as a component of contract escalation charges. However, as certain of our contracts are long-term in nature, cost increases may not be adjusted in our contract rates until the contracts are up for renewal.

Additionally, operation of a global fleet of aircraft requires us to carry spare parts inventory across our global operations to perform scheduled and unscheduled maintenance activity.  Changes in the aircraft model types of our fleet or the timing of exits from model types can result in inventory levels in excess of those required to support the fleet over the remaining life of the fleet.  Additionally, other parts may become obsolete or dormant given changes in use of parts on aircraft and maintenance needs.  These fleet changes or other external factors can result in impairment of inventory balances where we expect that excess, dormant or obsolete inventory will not recover its carrying value through sales to third parties or disposal.

Our future growth depends significantly on the level of international oil and gas activity and our ability to operate outside of the North Sea and the U.S. Gulf of Mexico.

Our future growth will depend significantly on our ability to expand into markets outside of the North Sea and the U.S. Gulf of Mexico. Expansion of our business depends on our ability to operate in these other regions.

Expansion of our business outside of the North Sea and the U.S. Gulf of Mexico may be adversely affected by:

• local regulations restricting foreign ownership of helicopter operators;

• requirements to award contracts to local operators; and

• the number and location of new drilling concessions granted by foreign governments.

We cannot predict the restrictions or requirements that may be imposed in the countries in which we operate. If we are unable to continue to operate or retain contracts in markets outside of the North Sea and the U.S. Gulf of Mexico, our operations outside of the North Sea and the U.S. Gulf of Mexico may not grow, and our future business, financial condition and results of operations may be adversely affected.

Our failure to attract and retain qualified personnel could have an adverse effect on us.

Loss of the services of key management personnel at our corporate and regional headquarters without being able to attract personnel of equal ability could have a material adverse effect upon us. Further, the Transportation Code in the U.S. and other statutes require our President and two-thirds of our board of directors and other managing officers be U.S. citizens. Our failure to attract and retain qualified executive personnel or for such executive personnel to work well together or as effective leaders in their respective areas of responsibility could have a material adverse effect on our current business and future growth.

Our ability to attract and retain qualified pilots, mechanics and other highly-trained personnel is an important factor in determining our future success. For example, many of our clients require pilots with very high levels of flight experience. The market for these experienced and highly-trained personnel is competitive and may become more competitive. Accordingly, we cannot assure you that we will be successful in our efforts to attract and retain such personnel. Some of our pilots, mechanics and other personnel, as well as those of our competitors, are members of military reserves who have been, or could be, called to active duty. If significant numbers of such personnel are called to active duty, it could reduce the supply of such workers and likely increase our labor costs. Additionally, the addition of new aircraft types to our fleet or a sudden change in demand for a specific aircraft type, as happened with the Sikorsky S-92 aircraft type in response to the H225 grounding, may require us to retain additional pilots, mechanics and other flight-related personnel.

A number of personnel departed the company during the current oil and gas industry downturn, and we may be unable to take advantage of current opportunities with our reduced workforce. We also may be unable to timely replace such personnel when the industry emerges from the current downturn. Our failure to attract and retain qualified personnel could have a material adverse effect on our current business and future growth.

Labor problems could adversely affect us.

Certain of our employees in the U.K., Norway, Nigeria, the U.S. and Australia (collectively, about 54% of our employees) are represented under collective bargaining or union agreements with 86% of these employees being represented by collective bargaining agreements and/or unions that have expired or will expire in one year. Disputes over the terms of these agreements or our potential inability to negotiate acceptable contracts with the unions that represent our employees under these agreements could result in strikes, work stoppages or other slowdowns by the affected workers. Periodically, certain groups of our employees who are not covered under a collective bargaining agreement consider entering into such an agreement. Further, if our unionized workers engage in an extended strike, work stoppage or other slowdown, other employees elect to become unionized, existing labor agreements are renegotiated, or future labor agreements contain terms that are unfavorable to us, we could experience a disruption of our operations or higher ongoing labor costs, which could adversely affect our business, financial condition and results of operations.

See Item 1. “Business — Employees” included elsewhere in this Annual Report for further discussion on the status of collective bargaining or union agreements.

Our operations are subject to weather-related and seasonal fluctuations.

Our operations can be impaired by harsh weather conditions. Poor visibility, high wind, heavy precipitation, sand storms and volcanic ash can affect the operation of helicopters and fixed wing aircraft and result in a reduced number of flight hours. A significant portion of our operating revenue is dependent on actual flight hours, and a substantial portion of our direct cost is fixed. Thus, prolonged periods of harsh weather can have a material adverse effect on our business, financial condition and results of operations. In addition, severe weather patterns, including those resulting from climate change, could affect the operation of helicopters and fixed wing aircraft and result in a reduced number of flight hours, which may have a material adverse effect on our business, financial condition and results of operations.

The fall and winter months have fewer hours of daylight, particularly in the North Sea and Canada. While some of our helicopters are equipped to fly at night, we generally do not do so. In addition, drilling activity in the North Sea and Canada is lower during the winter months than the rest of the year. Anticipation of harsh weather during this period causes many oil and gas companies to limit activity during the winter months. Consequently, flight hours are generally lower during these periods, typically resulting in a reduction in operating revenue during those months. Accordingly, our reduced ability to operate in harsh weather conditions and darkness may have a material adverse effect on our business, financial condition and results of operations.

The Harmattan, a dry and dusty West African trade wind, blows in Nigeria between the end of December and the middle of February. The heavy amount of dust in the air can severely limit visibility and block the sun for several days, comparable to a heavy fog. We are unable to operate aircraft during these harsh conditions. Consequently, flight hours may be lower during these periods resulting in reduced operating revenue, which may have a material adverse effect on our business, financial condition and results of operations.

In the U.S. Gulf of Mexico, the months of December through March typically have more days of harsh weather conditions than the other months of the year. Heavy fog during those months often limits visibility and flight activity. In addition, in the Gulf of Mexico, June through November is tropical storm and hurricane season, and in Australia, November through April is cyclone season. When a weather event is about to enter or begins developing in these regions, helicopter flight activity may increase because of evacuations of offshore workers. However, during such an event, we are unable to operate in the area of the storm. In addition, as a significant portion of our facilities are located along the coast of these regions, extreme weather may cause substantial damage to our property in these locations, including possibly aircraft. Additionally, we incur costs in evacuating our aircraft, personnel and equipment prior to tropical storms, hurricanes and cyclones.

Failure to develop or implement new technologies could affect our results of operations.

Many of the aircraft that we operate are characterized by changing technology, introductions and enhancements of models of aircraft and services and shifting client demands, including technology preferences. Our future growth and financial performance will depend in part upon our ability to develop, market and integrate new services and to accommodate the latest technological advances and client preferences. In addition, the introduction of new technologies or services that compete with our services could result in our revenue decreasing over time. If we are unable to upgrade our operations or fleet with the latest technological advances in a timely manner, or at all, our business, financial condition and results of operations could suffer.

We are increasingly dependent on information technology, and if we are unable to protect against service interruptions, data corruption, cyber attacks or network security breaches, our operations could be disrupted and our business could be negatively impacted.

Our business is increasingly dependent upon information technology networks and systems to process, transmit and store electronic and financial information, to capture knowledge of our business, and to communicate within our company and with clients, suppliers, partners and other stakeholders. These information technology systems, some of which are managed by third parties, may be susceptible to damage, disruptions or shutdowns due to failures during the process of upgrading or replacing software, databases or components thereof, power outages, hardware failures, computer viruses, cyber attacks, telecommunication failures, user errors or catastrophic events. Our information technology systems are becoming increasingly integrated on a global basis, so damage, disruption or shutdown to the system could result in a more widespread impact. If our information technology systems suffer severe damage, disruption or shutdown, and our business continuity plans do not effectively resolve the issues in a timely manner, we could experience business disruptions and transaction errors causing a material adverse effect on our business, financial condition and results of operations.

25

In addition, a breach or failure of our information technology systems could lead to potential unauthorized access and disclosure of confidential information, including the Personally Identifiable Information of our customers and employees, or violations of privacy or other laws. Any such breach could also lead to data loss, data corruption, communication interruption or other operational disruptions within our business. There is no assurance that we will not experience cyber attacks or security breaches and suffer losses in the future. As the methods of cyber attacks or security breaches continue to evolve, we may be required to expend additional resources to continue to modify or enhance our protective measures or to investigate and remediate any such event. Furthermore, the continuing and evolving threat of cyber attacks and security breaches has resulted in increased regulatory focus on prevention. To the extent we are subject to increased regulatory requirements, we may be required to expend additional resources to meet such requirements.

Downgrades in our credit ratings could impact our ability to access capital and materially adversely affect our business, financial condition and results of operations.

Credit rating agencies continually review their ratings for the companies that they follow, including us. Credit rating agencies also evaluate the industries in which we and our affiliates operate as a whole and may change their credit rating for us based on their overall view of such industries. Both Moody’s and Standard and Poor’s downgraded our ratings during 2017 as a result of the oil industry downturn and its effects on our financial results. There can be no assurance that any rating assigned to our currently outstanding public debt securities will remain in effect for any given period of time or that any such ratings will not be further lowered, suspended or withdrawn entirely by a rating agency if, in that rating agency’s judgment, circumstances so warrant.

A further downgrade of our credit ratings could, among other things:

• limit our ability to access capital or otherwise adversely affect the availability of other new financing on favorable terms, if at all;

• result in more restrictive covenants in agreements governing the terms of any future indebtedness that we may incur;

• cause us to refinance indebtedness with less favorable terms and conditions, which debt may require collateral and restrict, among other things, our ability to pay distributions or repurchase shares;

• increase our cost of borrowing;

• adversely affect the market price of our outstanding debt securities; and

• impair our business, financial condition and results of operation.

We operate in many international areas through entities that we do not control and are subject to government regulation that limits foreign ownership of aircraft companies in favor of domestic ownership.

We conduct many of our international operations through entities in which we have a noncontrolling investment or through strategic alliances with foreign partners. For example, we have acquired interests in, or in some cases have lease and service agreements with, entities that operate aircraft in Brazil, Canada and Egypt. We provide engineering and administrative support to certain of these entities. We derive significant amounts of lease revenue, service revenue, equity earnings and dividend income from these entities. In fiscal years 2018, 2017 and 2016, we received approximately $67.1 million, $71.5 million and $78.9 million, respectively, of revenue from the provision of aircraft and other services to unconsolidated affiliates. As a result of not owning a majority interest or maintaining voting control of our unconsolidated affiliates, we do not have the ability to control their policies, management or affairs. The interests of persons who control these entities or partners may differ from ours and may cause such entities to take actions that are not in our best interest. If we are unable to maintain our relationships with our partners in these entities, we could lose our ability to operate in these areas, potentially resulting in a material adverse effect on our business, financial condition and results of operations. Additionally, an operational incident involving one of the entities over which we do not have operational control may nevertheless cause us reputational harm.

We are subject to governmental regulation that limits foreign ownership of aircraft companies in favor of domestic ownership. Based on regulations in various markets in which we operate, our aircraft may be subject to deregistration and we may lose our ability to operate within these countries if certain levels of local ownership are not maintained. Deregistration of our aircraft for any reason, including foreign ownership in excess of permitted levels, could have a material adverse effect on our ability to conduct operations within these markets. We cannot assure you that there will be no changes in aviation laws, regulations or administrative requirements or the interpretations or applications thereof that could restrict or prohibit our ability to operate in certain regions. Any such restriction or prohibition on our ability to operate may have a material adverse effect on our business, financial condition and results of operations. See further discussion in Item 1. “Business — Governmental Regulation” included elsewhere in this Annual Report.

26

We are subject to legal compliance risks.

As a global business, we are subject to complex laws and regulations in the U.S., the U.K. and other countries in which we operate. These laws and regulations relate to a number of aspects of our business, including anti-bribery and anti-corruption laws, import and export controls, sanctions against business dealings with certain countries and third parties, the payment of taxes, employment and labor relations, fair competition, data privacy protections, securities regulation, and other regulatory requirements affecting trade and investment. The application of these laws and regulations to our business is often unclear and may sometimes conflict. Compliance with these laws and regulations may involve significant costs or require changes in our business practices that could result in reduced revenue and profitability. Non-compliance could also result in significant fines, damages, and other criminal sanctions against us, our officers or our employees, prohibitions or additional requirements on the conduct of our business and damage our reputation. Certain violations of law could also result in suspension or debarment from government contracts. We also incur additional legal compliance costs associated with our global regulations. In some foreign countries, particularly those with developing economies, it may be customary for others to engage in business practices that are prohibited by laws such as the FCPA, the U.K. Bribery Act and the BCCA in Brazil, an anti-bribery law that is similar to the FCPA and U.K. Bribery Act. Although we implement policies and procedures designed to ensure compliance with these laws, there can be no assurance that all of our employees, contractors, agents, and business partners will not take action in violation with our internal policies. Any such violation of the law or even internal policies could have a material adverse effect on our business, financial condition and results of operations.

Actions taken by agencies empowered to enforce governmental regulations could increase our costs and reduce our ability to operate successfully.

Our operations are regulated by governmental agencies in the various jurisdictions in which we operate. These agencies have jurisdiction over many aspects of our business, including personnel, aircraft and ground facilities. Statutes and regulations in these jurisdictions also subject us to various certification and reporting requirements and inspections regarding safety, training and general regulatory compliance. Other statutes and regulations in these jurisdictions regulate the offshore operations of our clients. The agencies empowered to enforce these statutes and regulations may suspend, curtail or require us to modify our operations. 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 (the “EASA”) issuing airworthiness directives prohibiting flight of H225LP and AS332L2 model aircraft. On July 20, 2017, the U.K. CAA and the Norway Aviation Agency (the “NCAA”) issued safety and operational directives that detail the conditions to apply for the safe return to service of H225LP and AS332L2 model aircraft, where operators wish to do so. We continue not to operate for commercial purposes our 24 H225LP model aircraft. We are carefully evaluating next steps and demand for the H225LP model aircraft in our oil and gas and SAR operations worldwide, with the safety of passengers and crews remaining our highest priority. However, additional directive requirements in the future could present North Sea operators, including us, with significant operational challenges. A suspension or substantial curtailment of our operations for any prolonged period, and any substantial modification of our current operations, could have a material adverse effect on our business, financial condition and results of operations. See further discussion in Item 1. “Business — Government Regulation” and “Business - Environmental” included elsewhere in this Annual Report.

Adverse results of legal proceedings could materially and adversely affect our business, financial condition and results of operations.

We are currently subject to and may in the future be subject to legal proceedings and claims that arise out of the ordinary conduct of our business. Results of legal proceedings cannot be predicted with certainty. Irrespective of merit, litigation may be both lengthy and disruptive to our operations and could cause significant expenditure and diversion of management attention. We may face significant monetary damages or injunctive relief against us that could materially adversely affect a portion of our business operations or materially and adversely affect our business, financial condition and results of operations should we not prevail in certain matters.

Negative publicity may adversely impact us.

Media coverage and public statements that insinuate improper actions by us, our unconsolidated affiliates, or other companies in our industry, regardless of their factual accuracy or truthfulness, may result in negative publicity, litigation or governmental investigations by regulators. Addressing negative publicity and any resulting litigation or investigations may distract management, increase costs and divert resources. Negative publicity may have an adverse impact on our reputation, the morale of our employees and the willingness of passengers to fly on our aircraft and those of our competitors, which could adversely affect our business, financial condition and results of operations.

27

Environmental regulations and liabilities may increase our costs and adversely affect us.

Our operations are subject to U.S. federal, state and local, and foreign environmental laws and regulations that impose limitations on the discharge of pollutants into the environment and establish standards for the treatment, storage, recycling and disposal of toxic and hazardous wastes. The nature of the business of operating and maintaining aircraft requires that we use, store and dispose of materials that are subject to environmental regulation. Environmental laws and regulations change frequently, which makes it impossible for us to predict their cost or impact on our future operations. Liabilities associated with environmental matters could have a material adverse effect on our business, financial condition and results of operations. We could be exposed to strict, joint and several liability for cleanup costs, natural resource damages and other damages as a result of our conduct that was lawful at the time it occurred or the conduct of, or conditions caused by, prior operators or other third parties. Additionally, any failure by us to comply with applicable environmental laws and regulations may result in governmental authorities taking action against us that could adversely impact our operations and financial condition, including the:

• issuance of administrative, civil and criminal penalties;

• denial or revocation of permits or other authorizations;

• imposition of limitations on our operations; and

• performance of site investigatory, remedial or other corrective actions.

Changes in environmental laws or regulations, including laws relating to greenhouse gas emissions or other climate change concerns, could require us to devote capital or other resources to comply with those laws and regulations. These changes could also subject us to additional costs and restrictions, including increased fuel costs. In addition, such changes in laws or regulations could increase costs of compliance and doing business for our customers and thereby decrease the demand for our services. Because our business depends on the level of activity in the offshore oil and gas industry, existing or future laws, regulations, treaties or international agreements related to greenhouse gases and climate change, including incentives to conserve energy or use alternative energy sources, could have a negative impact on our business if such laws, regulations, treaties or international agreements reduce the worldwide demand for oil and gas or limit drilling opportunities. For additional information see Item 1. “Business — Environmental” and Item 3. “Legal Proceedings” included elsewhere in this Annual Report.

Regulations limit foreign ownership of our company, which could reduce the price of our common stock and cause owners of our common stock who are not U.S. persons to lose their voting rights.

Our restated certificate of incorporation provides that persons or entities that are not “citizens of the U.S.” (as defined in the Federal Aviation Act) shall not collectively own or control more than 25% of the voting power of our outstanding capital stock (the “Permitted Foreign Ownership Percentage”) and that, if at any time persons that are not citizens of the U.S. nevertheless collectively own or control more than the Permitted Foreign Ownership Percentage, the voting rights of shares owned by stockholders who are not citizens of the U.S. shall automatically be suspended, in the reverse chronological order of the dates and times of registry of such shares in our stock records, until the voting rights of a sufficient number thereof shall have been suspended so that the number of shares owned by stockholders who are not citizens of the U.S. that continue to have voting rights equals the greatest whole number that is less than or equal to the Permitted Foreign Ownership Percentage. Shares held by persons who are not citizens of the U.S. may lose their associated voting rights and be redeemed as a result of these provisions. These restrictions may have a material adverse impact on the liquidity or market value of our common stock because holders may be unable to transfer our common stock to persons who are not citizens of the U.S.

28

If we do not restrict the amount of foreign ownership of our common stock, we might lose our status as a U.S. air carrier and be prohibited from operating aircraft in the U.S., which could adversely impact our business, financial condition and results of operations.

Since we hold the status of a U.S. air carrier under the regulations of both the U.S. Department of Transportation and the FAA and we engage in the operating and dry-leasing of aircraft in the U.S., we are subject to regulations pursuant to Title 49 of the Transportation Code (the “Transportation Code”) and other statutes (collectively, the “Aviation Acts”). The Transportation Code requires that certificates to engage in air transportation be held only by citizens of the U.S. as that term is defined in the relevant section of the Transportation Code. That section requires: (i) that our President and two-thirds of our board of directors and other managing officers be U.S. citizens; (ii) that at least 75% of our outstanding voting stock be owned by U.S. citizens; and (iii) that we must be under the actual control of U.S. citizens. Further, our aircraft operating in the U.S. must generally be registered in the U.S. In order to register such aircraft under the Aviation Acts, we must be owned or controlled by U.S. citizens. Although our restated certificate of incorporation and amended and restated by-laws contain provisions intended to ensure compliance with the provisions of the Aviation Acts, a failure to maintain compliance could result in the loss of our air carrier status prohibiting us from both operating as an air carrier and operating aircraft in the U.S. during any period in which we did not comply with these regulations, and thereby adversely affect our business, financial condition and results of operations.

Risks Relating to Our Level of Indebtedness

Our level of indebtedness could adversely affect our ability to obtain financing, impair our ability to fulfill our obligations under our indebtedness and limit our ability to adjust to changing market conditions.

We have substantial debt and substantial debt service requirements. As of March 31, 2018, we had approximately $1.5 billion of outstanding indebtedness, including long-term debt. In addition, 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. Although certain of our debt agreements contain restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of qualifications and exceptions.

Our level of indebtedness may have important consequences to our business, including:

• impairing our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions or other general corporate purposes;

• requiring us to dedicate a substantial portion of our cash flow to the payment of principal and interest on our indebtedness, which reduces the availability of our cash flow to fund working capital, capital expenditures, acquisitions and other general corporate purposes or to repurchase our debt upon a change of control;

• subjecting us to the risk of increased sensitivity to interest rate increases on our indebtedness with variable interest rates, including future borrowings under our ABL Facility;

• increasing the possibility of an event of default under certain covenants contained in our debt agreements; and

• limiting our ability to adjust to rapidly changing market conditions, reducing our ability to withstand competitive pressures and making us more vulnerable to a downturn in general economic conditions or our business than our competitors with less debt.

If we are unable to generate sufficient cash flow from operations in the future to service our debt, we may be required to refinance all or a portion of our existing debt or obtain additional financing. There is no assurance that any such refinancing could be possible or that any additional financing could be obtained. Our inability to obtain such refinancing or financing could have a material adverse effect on us.

29

To service our indebtedness and lease obligations we will continue to require a significant amount of cash, and our ability to generate cash depends on many factors beyond our control.

Our ability to make scheduled payments of principal or interest with respect to our indebtedness and lease obligations will depend on our ability to generate cash and on our financial results. Our ability to generate cash depends on the demand for our services, which is subject to levels of activity in offshore oil and gas exploration, development and production, general economic conditions, the ability of our affiliates to generate and distribute cash flows, and financial, competitive, regulatory and other factors affecting our operations, many of which are beyond our control. We cannot assure you that our operations will generate sufficient cash flow or that future borrowings will be available to us under our ABL Facility or otherwise in an amount sufficient to enable us to pay our indebtedness or lease obligations or to fund our other liquidity needs.

Covenants in our debt agreements may restrict the manner in which we can operate our business.

The indentures governing our 6¼% Senior Notes due 2022 (the “6¼% Senior Notes”) and our 8.75% Senior Secured Notes due 2023 (the “8.75% Senior Secured Notes”) limit, among other things, our ability and the ability of our restricted subsidiaries to:

• borrow money or issue guarantees;

• pay dividends, redeem capital stock or make certain other restricted payments;

• incur liens to secure indebtedness;

• make certain investments;

• sell certain assets;

• enter into transactions with our affiliates; or

• merge with another person or sell substantially all of our assets.

If we fail to comply with these and other covenants, we would be in default under our aggregate $200 million U.S. dollar equivalent loans from Lombard North Central Plc, a part of the Royal Bank of Scotland (the “Lombard Debt”), $200 million loan from the Macquarie Bank Limited (the “Macquarie Debt”), $230 million term loan credit agreement with PK AirFinance S.à r.l., as agent, and PK Transportation Finance Ireland Limited, as lender, and other lenders from time to time party thereto (the “PK Air Debt”) and ABL Facility (together, our “Credit Facilities”) and the indentures governing the 6¼% Senior Notes and the 8.75% Senior Secured Notes, and the principal and accrued interest on our outstanding indebtedness may become due and payable. In addition, our Credit Facilities and other debt agreements contain, and our future debt agreements may contain, similar and additional affirmative and negative covenants. Our Credit Facilities and the 8.75% Senior Secured Notes are secured by many of our assets (including most of our helicopters), and such assets may not be available to secure additional financings. As a result, our ability to respond to changes in business and economic conditions and to obtain additional financing, if needed, may be significantly restricted, and we may be prevented from engaging in transactions that might otherwise be considered beneficial to us.

Our debt agreements, including our Credit Facilities and the indentures governing the 6¼% Senior Notes, the 8.75% Senior Secured Notes and the 4½% Convertible Senior Notes due 2023 (the “4½% Convertible Senior Notes”), also require us or certain of our subsidiaries, and our future credit facilities may require us or certain of our subsidiaries, to observe certain covenants. Our ability to observe certain of those covenants can be affected by events beyond our control, and we cannot assure you that we will be able to observe these covenants in the future. The breach of any of these covenants could result in a default under our other debt agreements. Upon the occurrence of an event of default under our Credit Facilities, any future credit facilities or the indentures governing the 6¼% Senior Notes, the 8.75% Senior Secured Notes and the 4½% Convertible Senior Notes, our creditors could elect to declare some or all amounts outstanding thereunder, including accrued interest or other obligations, to be immediately due and payable. There can be no assurance that our assets would be sufficient to repay all of our indebtedness in full.

The agreements governing certain of our indebtedness, including our Credit Facilities, the indentures governing the 6 ¼% Senior Notes, the 8.75% Senior Secured Notes and the 4½% Convertible Senior Notes contain cross-default provisions. Under these provisions, a default under one agreement governing our indebtedness may constitute a default under our other debt agreements.

Failure to comply with covenants contained in certain of our lease agreements could limit our ability to maintain our leased aircraft fleet and could adversely affect our business.

We have a significant amount of fixed obligations related to operating leases, including aircraft leases. The terms of our aircraft lease agreements contain covenants that impose certain limitations on us. Such lease agreements limit, among other things, our ability to utilize aircraft in certain jurisdictions and/or to sublease aircraft, and may contain restrictions upon a change of control. A breach of lease covenants could result in an obligation to repay amounts outstanding under the lease, including rent. A breach of lease covenants with respect to the return of aircraft to our lessors could also result in an obligation to pay holdover rent beyond the scheduled lease expiration date for such aircraft and/or increased maintenance and repair costs. If any such event occurs, we may not be able to pay all amounts due under the leases or to refinance such leases on terms satisfactory to us or at all, which could have a material adverse effect on our business, financial condition and results of operations.

Item 1B.Unresolved Staff Comments

None.

Item 2.Properties

The number and types of aircraft we operate are described in Item 1. “Business — Overview” above. In addition, we lease various office and operating facilities worldwide, including facilities at the Acadiana Regional Airport in New Iberia, Louisiana, the Redhill Aerodrome near London, England, the Aberdeen Airport, Scotland, along the U.S. Gulf of Mexico and in Bergen and Stavanger, Norway, and numerous residential locations near our operating bases or the bases of our affiliates in the U.K., Norway, Australia, Russia, Nigeria, Canada and Trinidad, which we use primarily for housing pilots and staff supporting those operations. We have ten SAR bases as follows: Caernarfon, Humberside, Inverness, Lee-on-Solent, Lydd, Newquay, Prestwick, St. Athan, Stornoway and Sumburgh. We also lease office space in a building in Houston, Texas, which we use as our corporate headquarters and for other business purposes. Eastern Airways owns a majority controlling stake in the Humberside Airport in Kirmington, United Kingdom. These facilities are generally suitable for our operations and can be replaced with other available facilities if necessary.

Additional information about our properties can be found in Note 7 in the “Notes to Consolidated Financial Statements” included elsewhere in this Annual Report (under the captions “Aircraft Purchase Contracts” and “Operating Leases”). A detail of our long-lived assets by geographic area as of March 31, 2018 and 2017 can be found in Note 11 in the “Notes to Consolidated Financial Statements” included elsewhere in this Annual Report.

Item 3.Legal Proceedings

Environmental Contingencies

The EPA has in the past notified us that we are a potential responsible party, or PRP, at three former waste disposal facilities that are on the National Priorities List of contaminated sites. Under the Superfund law, persons who are identified as PRPs may be subject to strict, joint and several liability for the costs of cleaning up environmental contamination resulting from releases of hazardous substances at National Priorities List sites. 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 these sites is not likely to have a material adverse effect on our business, financial condition and results of operations.

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 various risk retention factors. We also are a defendant in certain claims and litigation arising out of operations in the normal course of business. In the opinion of management, uninsured losses, if any, will not be material to our financial position, results of operations or cash flows.

Item 4.Mine Safety Disclosures

None.

Item 7.Management’s Discussion and Analysis of Financial Condition and Results of Operations

Management’s Discussion and Analysis of Financial Condition and Results of Operations, or MD&A, should be read in conjunction with “Forward-Looking Statements,” Item 1A. “Risk Factors” and our Consolidated Financial Statements for fiscal years 2018, 2017 and 2016, and the related notes thereto, all of which are included elsewhere in this Annual Report.

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 the Explanatory Note and “Liquidity and Capital Resources — Financial Condition and Sources of Liquidity” included elsewhere in this Annual Report.

See discussion of our business and the operations within our industrial aviation services segment under Item 1. “Business — Overview” included elsewhere in this Annual Report.

Our Strategy

Our goal is to further strengthen our position as the leading industrial aviation services provider to the offshore energy industry and public and private sector SAR. 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.

As we move into fiscal year 2019, 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 note maturities in absence of an offshore market recovery. 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 Zero performance with regard to our air accidents and 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 clients 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 new Europe and Americas hub structure discussed elsewhere in this Annual Report has allowed us to achieve reductions in general and administrative expenses down to approximately 12% of revenue. Further, 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 clients for contracts measured in months rather than years. Our ability to service this demand led to significant outperformance versus internal expectations across many of our regions during fiscal year 2018.

• Improve Balance Sheet and Return on Capital. We seek to continue 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), return to profitability and improvement of return on invested capital. To achieve this we have historically practiced the principal of prudent balance sheet management and have proactively managed our liquidity position with cash flows from operations, as well as external financings. These external financings have included 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 March 31, 2018, commercial helicopters under operating leases accounted for 40% of our LACE. See “Liquidity and Capital Resources —Financial

35

Condition and Sources of Liquidity” included elsewhere in this Annual Report for further discussion of our capital structure and liquidity.

• Value Added Acquisitions and Divestitures. We intend to pursue value-added acquisitions 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. 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. We currently have 11 aircraft held for sale and the average age of our fleet is approximately nine years. Additionally, our critical short and long-term goal is to significantly reduce our aircraft rent expense. During fiscal year 2018 and April 2018, we returned four Airbus H225s and six Sikorsky S-92s. The reduction of aircraft rent expense from these lease returns is just beginning and is a fundamental plank of our ongoing strategy to return to profitability.

• Execute on Bristow Transformation. Our new 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 Annual 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 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 client diversity which helps mitigate risks associated with a single market or client.

The oil and gas business environment experienced a significant downturn beginning during fiscal year 2015. Brent crude oil prices declined from approximately $106 per barrel at July 1, 2014 to a low of approximately $26 per barrel in February 2016, with an increase to approximately $65 per barrel as of March 31, 2018. The decrease in oil prices was driven by increased global supply 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 clients and resulted in their implementation of measures to reduce operational and capital costs, negatively impacting activity beginning in fiscal year 2015. These cost reductions have continued into fiscal year 2018 and have impacted both the offshore production and the offshore exploration activity of our clients, with offshore production activity being impacted to a lesser extent. Although the largest share of our revenue relates to oil and gas production and our largest contract, the U.K. SAR contract (as defined herein), is not directly impacted by declining oil prices, 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 since 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 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, which in turn reduces our oil and gas clients’ costs and generates increased demand for offshore transportation like helicopters. Our success in reducing costs 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 as 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 clients 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.

36

Additionally, we have taken 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 clients to improve the efficiency of their operations. As discussed above, 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 and completed the sale of $350 million of the 8.75% Senior Secured Notes. In April 2018, we entered into a new ABL Facility. For further details, see Note 4 in the “Notes to Consolidated Financial Statements” included elsewhere in this Annual 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 achieved $136.0 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.

Recent Events

ABL Facility — On April 17, 2018, two of our subsidiaries entered into a new 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 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.

8.75% Senior Secured Notes — On March 6, 2018, we issued and sold $350 million of the 8.75% Senior Secured Notes. The 8.75% Senior Secured Notes bear interest at a rate of 8.75% per year, payable semi-annually in arrears on March 1 and September 1 of each year, beginning on September 1, 2018. The 8.75% Senior Secured Notes will mature on March 1, 2023, subject to earlier mandatory redemption if more than $125 million principal amount of the 6¼% Senior Notes plus the principal amount of any indebtedness incurred to refinance the 6¼% Senior Notes that matures or is required to be repaid prior to June 1, 2023 remains outstanding as of June 30, 2022. The proceeds of the 8.75% Senior Secured Notes were used, among other things, to repay the then-remaining $52.6 million of our $350 million term loan (the “Term Loan”), to cash collateralize certain outstanding letters of credit existing under our $400 million revolving credit facility (the “Revolving Credit Facility”) and for general corporate purposes. We terminated the Term Loan and the Revolving Credit Facility in March 2018. Additional details regarding the 8.75% Senior Secured Notes, the Term Loan and the Revolving Credit Facility are provided in Note 4 in the “Notes to Consolidated Financial Statements” included elsewhere in this Annual Report.

4½% Convertible Senior Notes — On December 18, 2017, we issued and sold $143.8 million of 4½% Convertible Senior Notes. The proceeds were used to repay $89.6 million of the Term Loan and to pay $10.1 million of the cost of the convertible note hedge transactions entered into in connection with the 4½% Convertible Senior Notes, with the remainder available for general corporate purposes. Additional details regarding the 4½% Convertible Senior Notes are provided in Note 4 in the “Notes to Consolidated Financial Statements” included elsewhere in this Annual 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 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 that will be applicable to us beginning in fiscal year 2019: (1) creation of a new minimum tax on base

37

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. 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. Consistent with guidance in SAB 118, we recorded provisional amounts for the transition tax on undistributed earnings of $52.9 million, which was partially offset by foreign tax credits of $22.6 million. We also recorded $53.0 million tax benefit as a result of the revaluation of our net deferred tax liabilities. Additional details regarding the Act and the impact on us are provided in Note 8 in the “Notes to Consolidated Financial Statements” included elsewhere in this Annual Report. 

We are continuing to analyze additional information to determine the final impact as well as other impacts of the Act. Any adjustments recorded to the provisional amounts will be included in income from operations as an adjustment to our fiscal year 2019 financial statements.

Bristow Academy sale — On November 1, 2017, we sold our 100% interest in Bristow Academy, as we continue to execute on our priority to optimize our business portfolio to improve our competitive position during the market downturn. The sales price is a minimum of $1.5 million to be received over a maximum of four years with potential additional consideration based on Bristow Academy’s financial performance.

The sale includes Bristow Academy’s entire operation, including training facilities, helicopters and related personnel, at Titusville, Florida, and Minden, Nevada. The sale does not impact recurrent training of Bristow flight crews for ongoing commercial operations. Initial type rating and recurrent pilot training for commercial operations will continue at Bristow’s flight-simulator training facilities located in Aberdeen, Scotland, and New Iberia, Louisiana, supplemented with the use of other globally located training centers.

The sale of this non-core business resulted in total charges recorded in the fiscal year 2018 of $7.2 million, which resulted from the combined loss on the sale and related impairment of assets included in loss on disposal of assets on our consolidated statement of operations.

With the completion of this sale and similar dispositions of non-core assets in prior fiscal years, we have streamlined our business to focus on our core oil and gas, SAR and fixed wing businesses globally. No significant non-core assets outside of these key areas of concentration remain upon completion of this sale.

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 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 that detail the conditions to apply for the safe return to service of H225LP and AS332L2 model aircraft, where operators wish to do so. We continue not to operate for commercial purposes our 24 H225LP model aircraft. We are carefully evaluating next steps and demand for the H225LP model aircraft in our oil and gas and SAR operations worldwide, with the safety of passengers and crews remaining our highest priority.

Separately, our efforts to successfully integrate AW189 aircraft into service for the U.K. SAR contract have been delayed due to a product improvement plan with the aircraft. As a result, the acceptance of four AW189 aircraft will be pushed to later dates. We 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 in May 2018. For further details on the accounting for these recoveries, see Note 3 in the “Notes to Consolidated Financial Statements” included elsewhere in this Annual Report.

PK Air Debt — On July 17, 2017, a wholly-owned subsidiary entered into a term loan credit agreement with PK AirFinance S.à r.l., as agent, and PK Transportation Finance Ireland Limited, as lender, and other lenders from time to time party thereto, which provided for commitments in an aggregate amount of up to $230 million to make up to 24 term loans, each of which term loans shall be made in respect of an aircraft to be pledged as collateral for all of the term loans. The term loans also will be secured by a pledge of all shares of the borrower and any other assets of the borrower, and will be guaranteed by the Company. The financing funded in September 2017 and proceeds from the financing were used to repay $17.0 million of the $200 million of term loan commitments (the “Term Loan Credit Facility”), $93.7 million of the Term Loan and $103.0 million of the Revolving Credit Facility. Additionally, in October 2017, we paid off the remaining $28.9 million of the Term Loan Credit Facility.

Structural and leadership changes — As discussed under “— Our Strategy” above, on June 8, 2017, we announced structural and leadership changes with two geographical hubs in key areas of business, Europe and the Americas. These changes resulted in a more regionally focused, cost efficient and competitive business positioned to win more contracts. We believe these changes will result in a smaller, more nimble company, with the same intense focus on delivering safe, reliable service to customers, and positioned for future growth and profitability.

Our Europe hub includes Africa, Asia, Australia, Norway, U.K., Turkmenistan and the Middle East. Our Americas hub includes the U.S. Gulf of Mexico, Guyana, Trinidad, Canada and Brazil, and had included Bristow Academy prior to its sale on November 1, 2017. Despite these structural changes, we are still operating primarily out of the four operating regions previously discussed and therefore have not made any changes to the regional disclosure of results for our industrial aviation services segment operations in this Annual Report.

The structural change into two primary hubs is expected to generate significant cost savings, in part through lower general and administrative costs. In conjunction with this announcement, we also announced a number of leadership changes, which included the elimination of certain management roles and other corporate positions.

The decision by Nigeria’s central bank to move to market-driven foreign currency trading — On June 20, 2016, Nigeria’s central bank abandoned its 16-month peg to the U.S. dollar, which resulted in a 38% devaluation of the naira versus the U.S. dollar from June 20 to June 30, 2016 and an additional 21% further devaluation of the naira versus the U.S. dollar from June 30, 2016 to March 31, 2018. For discussion of the impact of changes in foreign currency exchange rates, including the naira, on our results, see “— Overview of Operating Results — Fiscal Year 2018 Compared to Fiscal Year 2017” included elsewhere in this Annual Report.

Impact of fleet changes — The management of our global aircraft fleet involves a careful evaluation of the expected demand for industrial aviation services across global energy markets, including the type of aircraft needed to meet this demand. As offshore oil and gas drilling and production globally moves to deeper water, more medium and large aircraft and newer technology aircraft may be required. As older aircraft models come off of current contracts and are replaced by new aircraft, our management evaluates our future needs for these aircraft models and ultimately the ability to recover our remaining investments in these aircraft through sales into the aftermarket. We depreciate our aircraft over their expected useful life to the expected salvage value to be received for the aircraft at the end of that life. Depending on the market for aircraft or changes in the expected future use of aircraft within our fleet, we may record gains or losses on aircraft sales, impairment charges for aircraft operating or held for sale, or accelerate or increase depreciation on aircraft used in our operations. In certain instances where a cash return can be made on newer aircraft in excess of the expected return available through the provision of industrial aviation services, we may sell newer aircraft. The number of aircraft sales and the amount of gains and losses recorded on these sales is unpredictable. While aircraft sales are common in our business and are reflected in our operating results, gains and losses on aircraft sales may result in our operating results not reflecting the ordinary operating performance of our primary business, which is providing industrial aviation services to our clients. The gains and losses on aircraft sales and any impairment charges are not included in the calculation of adjusted EBITDA, adjusted net income (loss) or adjusted earnings (loss) per share.

In recent years, we have seen deterioration in market sales for aircraft resulting mostly from an increase in idle aircraft and reduced demand across the offshore energy market. While other markets exist for certain aircraft model types, including utility, firefighting, government, VIP transportation and tourism, the market for certain model type aircraft slowed. As a result of these market changes, we recorded impairment charges of $15.9 million related to eight held for sale aircraft during fiscal year 2018, $12.5 million related to 14 held for sale aircraft during fiscal year 2017 and $29.6 million related to 16 held for sale aircraft during fiscal year 2016. Additionally, due to changes in estimated salvage values for our fleet of operational aircraft and other changes in the timing of exiting certain aircraft from our operations, we recorded an additional $10.4 million and $28.7 million in depreciation expense during fiscal years 2017 and 2016, respectively.

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 March 31, 2018 is $62.3 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 March 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 from unconsolidated affiliates. Earnings from unconsolidated affiliates, net of losses, 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.

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 fiscal year 2018, 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 details on this exposure and the related impact on our results of operations, see “Item 7A. Quantitative and Qualitative Disclosures about Market Risk” and Note 1 in the “Notes to Consolidated Financial Statements” included elsewhere in this Annual Report.

⁽¹⁾  Operating margin is calculated as operating income (loss) divided by operating revenue. Adjusted EBITDA margin is calculated as adjusted EBITDA divided by operating revenue.

⁽²⁾  Excludes flight hours from Bristow Academy and unconsolidated affiliates. Includes flight hours from Eastern Airways and Airnorth fixed wing operations in the U.K., Nigeria and Australia for fiscal years 2018, 2017 and 2016 of 43,192, 39,873 and 41,473, respectively.

⁽³⁾  These financial measures have not been prepared in accordance with 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 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 fiscal years 2018, 2017 and 2016 under “Fiscal Year 2018 Compared to Fiscal Year 2017” and “Fiscal Year 2017 Compared to Fiscal Year 2016” below.

⁽ⁱⁱ⁾  Effective tax rate is calculated by dividing benefit (provision) for income tax by pretax net income. Adjusted effective tax rate is calculated by dividing adjusted benefit (provision) for income tax by adjusted pretax net income (loss). Tax expense (benefit) on loss on disposal of asset and tax expense (benefit) on special items is calculated using the statutory rate of the entity recording the loss on disposal of asset 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 earnings per share is calculated using the diluted weighted average number of shares outstanding of 35,288,579, 35,044,040 and 34,893,844 for fiscal years 2018, 2017 and 2016, respectively.

Management believes that adjusted EBITDA, adjusted benefit (provision) for income taxes, adjusted net income (loss) and adjusted diluted earnings (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.

Adjusted net income (loss) and adjusted diluted earnings (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 income and diluted earnings 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.

Corporate and other	4,278		10,037		(5,759		)	(57.4	)%
Total operating revenue	$	1,384,424	$	1,347,850	$	36,574		2.7	%

The year-over-year increase in operating revenue was primarily driven by the increase in U.K. SAR services revenue due to additional bases coming online in fiscal years 2017 and 2018 and the increase in operating revenue from our fixed wing services in our Europe Caspian, Asia Pacific and Africa regions. These increases were partially offset by a decrease in our oil and gas services driven by declines in our Africa and Asia Pacific regions, partially offset by increases in oil and gas services in our Americas and Europe Caspian regions. See further discussion of operating revenue by region under “— Region Operating Results.” In addition to operational impacts, changes in foreign currency exchange rates during fiscal year 2018 resulted in $14.1 million of the increase year-over-year in gross revenue.

We reported a net loss of $195.7 million and $170.5 million and a diluted loss per share of $5.54 and $4.87 for fiscal years 2018 and 2017, respectively. The year-over-year increase in net loss and diluted loss per share was primarily driven by a higher loss on impairment, the decline in oil and gas services revenue and higher interest expense. These unfavorable changes were partially offset by the higher revenue from U.K. SAR and fixed wing services in fiscal year 2018 discussed above, a tax benefit in fiscal year 2018 compared to tax expense in fiscal year 2017 and a decrease in general and administrative expense.

The net loss for fiscal year 2018 was significantly impacted by the following items:

• Loss on impairment totaling $91.4 million, including:

▪ Impairment of investment in unconsolidated affiliates of $85.7 million ($58.7 million net of tax) related to impairment of our investment in Líder in Brazil, and

▪ Impairment of inventories of $5.7 million ($4.6 million net of tax);

45

• Organizational restructuring costs of $23.6 million ($17.6 million net of tax), which includes severance expense of $22.3 million related to separation programs across our global organization designed to increase efficiency and reduce costs and other restructuring costs of $1.3 million; $11.6 million of restructuring costs are included in direct costs and $12.0 million are included in general and administrative expense; and

• Early extinguishment of debt of $3.1 million ($2.1 million net of tax) included in interest expense, which includes $3.0 million related to write-off of deferred financing fees and $0.1 million related to write-off of discount on debt; partially offset by

• A non-cash benefit of $22.9 million from tax items, including a $53.0 million benefit related to the revaluation of net deferred tax liabilities to a lower tax rate as a result of the Act and net reversal of valuation allowances on deferred tax assets of $2.6 million, partially offset by the impact of the one-time transition tax on the repatriation of foreign earnings under the Act of $30.3 million and a one-time non-cash tax expense of $2.4 million from repositioning of certain aircraft from one tax jurisdiction to another related to recent financing transactions.

Additionally, we had a loss on disposal of assets of $17.6 million ($60.5 million net of tax, including an additional $40.1 million in tax resulting from the repositioning of certain aircraft from one tax jurisdiction to another related to recent financing transactions) during fiscal year 2018 primarily related to $15.9 million for impairment charges on assets held for sale (including a $7.2 million impairment and loss on disposal related to the Bristow Academy sale).

Excluding the special items described above and the loss on disposal of assets, adjusted net loss and adjusted diluted loss per share were $75.0 million and $2.13, respectively, for fiscal year 2018. These adjusted results compare to adjusted net loss and adjusted diluted loss per share of $74.5 million and $2.13, respectively, for fiscal year 2017. Adjusted EBITDA increased to $105.4 million in fiscal year 2018 from $71.1 million in fiscal year 2017.

The year-over-year increase in adjusted EBITDA was primarily driven by higher revenue from U.K. SAR and fixed wing services in fiscal year 2018 discussed above and a decrease in general and administrative expense primarily from lower salaries and benefits in fiscal year 2018. These favorable changes were partially offset by the decline in oil and gas revenue discussed above. Adjusted net loss and diluted earnings per share were impacted by the same items that impacted adjusted EBITDA, as well as increased tax benefit offset by higher interest expense. Results for fiscal year 2018 were also positively impacted by a reduction in rent expense of $16.6 million included in direct costs related to OEM cost recoveries.

The table below presents the year-over-year impact of changes in foreign currency exchange rates.

	Fiscal Years Ended March 31,						Favorable (Unfavorable)
	2018			2017
	(in thousands, except per share amounts)
Revenue impact							$	14,150
Operating expense impact							(16,178		)
Year-over-year income statement translation							(2,028		)
Transaction losses included in other income (expense), net	$	(2,580	)	$	(2,948	)	368
Líder foreign exchange impact included in earnings from unconsolidated affiliates	(1,956		)	(3,193		)	1,237
Total	$	(4,536	)	$	(6,141	)	1,605

Less: Foreign exchange impact on depreciation and amortization and interest expense							1,282
Adjusted EBITDA impact							$	859
Net income impact (tax affected)							$	2,993
Earnings per share impact							$	0.08

Direct costs increased 1.7%, or $19.2 million, year-over-year primarily due to a $21.4 increase in maintenance expense and a $13.7 million increase in fuel, both of which are primarily due to an increase in activity, partially offset by a $6.1 million decrease in freight costs due to higher shipping costs incurred during fiscal year 2017 in our Africa region to move aircraft back to the U.S. to be sold, a $5.7 million decrease in rent expense primarily due to OEM credits and $4.1 million decrease in various other costs.

Reimbursable expense increased 18.0%, or $9.0 million, primarily due to new contracts in Australia and Norway.

46

Depreciation and amortization increased 4.5%, or $5.3 million, to $124.0 million for fiscal year 2018 from $118.7 million for fiscal year 2017. This increase in depreciation and amortization expense is primarily due to additional new aircraft and information technology costs being capitalized and depreciated in fiscal year 2018, partially offset by a $2.8 million reduction in depreciation expense related to OEM cost recoveries. Additionally, we recorded accelerated depreciation of $10.4 million in fiscal year 2017 as a result of fleet changes for older aircraft.

General and administrative expense decreased 5.3%, or $10.4 million, in fiscal year 2018, as compared to fiscal year 2017 primarily due to a $7.2 million decrease in compensation expense from lower salaries and benefits due to a reduction in corporate headcount and a $5.3 million decrease in professional fees, partially offset by a $2.1 million increase in various other costs primarily including rent expense.

Loss on impairment for fiscal year 2018 includes the items discussed above. Loss on impairment for fiscal year 2017 includes $8.7 million of goodwill impairment related to Eastern Airways and $7.6 million of inventory impairments.

Loss on disposal of assets increased $3.1 million to a loss of $17.6 million for fiscal year 2018 from a loss of $14.5 million for fiscal year 2017. The loss on disposal of assets in fiscal year 2018 included impairment charges of $8.7 million related to assets held for sale, a loss of $1.7 million from the sale or disposal of aircraft and other equipment and a $7.2 million impairment and loss on disposal related to the Bristow Academy sale. During fiscal year 2017, the loss on disposal of assets included impairment charges of $12.5 million related to assets held for sale and a loss of $2.0 million from the sale or disposal of aircraft and other equipment.

Earnings from unconsolidated affiliates, net of losses, decreased $0.2 million to earnings of $6.7 million for fiscal year 2018 from earnings of $6.9 million in fiscal year 2017. The decrease primarily resulted from earnings from our investment in Líder in Brazil of $7.2 million for fiscal year 2018 compared to $8.1 million in fiscal year 2017 primarily due to a decline in activity, partially offset by less of an unfavorable impact of foreign currency exchange rates. Our earnings from Líder in fiscal years 2018 and 2017 were reduced by the unfavorable impact of foreign currency exchange rate changes of $2.0 million and $3.2 million, respectively.

Interest expense, net, increased 54.4%, or $27.1 million, year-over-year primarily due to an increase in interest expense resulting from an increase in borrowings at higher borrowing rates and a decrease in capitalized interest resulting from lower average construction in progress. Additionally, during fiscal year 2018, we wrote-off $3.0 million of deferred financing fees related to the early extinguishment of debt.

Other income (expense), net increased $0.4 million to other expense of $3.1 million for fiscal year 2018 compared to other expense of $2.6 million for fiscal year 2017 primarily due to higher foreign currency transaction losses in fiscal year 2018 compared to fiscal year 2017. For further details on other income (expense), net, see “— Region Operating Results — Other Income (Expense), Net” included elsewhere in this Annual Report.

For further details on income tax expense, see “— Region Operating Results — Taxes” included elsewhere in this Annual Report.

47

As discussed above, our results for fiscal year 2018 were impacted by a number of special items. In fiscal year 2017, special items that impacted our results included organizational restructuring costs, loss on impairment (goodwill and inventories), additional depreciation expense resulting from fleet changes, the reversal of Airnorth contingent consideration and tax items. For further details on the special items impacting fiscal year 2017, see “— Fiscal Year 2017 Compared to Fiscal Year 2016” below. The items noted in fiscal years 2018 and 2017 have been identified as special items as they are not considered by management to be part of ongoing operations when assessing and measuring the operational and financial performance of the Company. The impact of these items on adjusted EBITDA, adjusted net loss and adjusted diluted loss per share is as follows:

	Fiscal Year Ended March 31, 2018
	Adjusted EBITDA			Adjusted Net Loss			Adjusted Diluted Loss Per Share
	(In thousands, except per share amounts)

Fiscal Year 2017 Compared to Fiscal Year 2016

As discussed under “— Market Outlook” above, the oil and gas industry experienced a significant downturn beginning in fiscal year 2015 that resulted in a significant decrease in gross revenue for our oil and gas and fixed wing services in fiscal year 2017 compared to fiscal year 2016. This decline in revenue was partially offset by the start-up of the U.K. SAR contract in April 2015 with seven bases coming online in fiscal year 2016 and an eighth base coming online in fiscal year 2017.

Operating revenue from external clients by line of service was as follows:

	Fiscal Year Ended March 31,				Favorable (Unfavorable)
	2017		2016
	(In thousands, except percentages)
Oil and gas services	$	956,649	$	1,222,501	$	(265,852	)	(21.7	)%
Fixed wing services	191,609		208,538		(16,929		)	(8.1	)%
U.K. SAR services	189,555		177,230		12,325			7.0	%
Corporate and other	10,037		21,278		(11,241		)	(52.8	)%
Total operating revenue	$	1,347,850	$	1,629,547	$	(281,697	)	(17.3	)%

In addition to operational decreases, changes in foreign currency exchange rates during fiscal year 2017 resulted in $80.3 million of the decrease year-over-year.

We reported a net loss of $170.5 million and $72.4 million and diluted loss per share of $4.87 and $2.12 for fiscal years 2017 and 2016, respectively. The year-over-year increase in net loss and diluted loss per share primarily resulted from the decline in oil and gas revenue discussed above, higher interest expense as a result of additional borrowings and increased income tax charges, partially offset by a lower loss on impairment, a lower loss from disposal of assets, lower depreciation and amortization expense due to less accelerated depreciation and less of an unfavorable impact from changes in foreign currency exchange rates.

48

The net loss for fiscal year 2017 was significantly impacted by the following items:

• Organizational restructuring costs of $20.9 million ($15.0 million net of tax), which includes severance expense of $16.9 million related to separation programs across our global organization designed to increase efficiency and reduce costs and other restructuring costs of $4.0 million; $7.6 million of the restructuring costs are included in direct costs and $13.3 million are included in general and administrative expense,

• Loss on disposal of assets of $14.5 million ($8.0 million net of tax) and on inventory of $7.6 million ($5.4 million net of tax) included in loss on impairment,

• Reversal of $5.9 million ($5.9 million net of tax) of contingent consideration related to the Airnorth acquisition, and

• Tax items of $59.5 million that include a one-time non-cash tax effect from repositioning of certain aircraft from one tax jurisdiction to another related to financing transactions resulting in additional income tax expense of $22.5 million and non-cash adjustments related to the valuation of deferred tax assets of $37.0 million.

Excluding these items, adjusted net loss and adjusted diluted loss per share were $74.5 million and $2.13, respectively, for fiscal year 2017. These adjusted results compare to adjusted net income and adjusted diluted earnings per share of $51.3 million and $1.45, respectively, for fiscal year 2016. Adjusted EBITDA, which excludes these items with the exception of accelerated depreciation and the tax items, also decreased year-over-year to $71.1 million in fiscal year 2017 from $205.5 million in fiscal year 2016. The year-over-year decrease in each of these measures primarily resulted from the decline in oil and gas revenue across all regions discussed above partially offset by less of an unfavorable impact from changes in foreign currency exchange rates year-over-year. See further discussion of operating results by region under “—Region Operating Results —Fiscal Year 2017 Compared to Fiscal Year 2016” included elsewhere in this Annual Report.

The table below presents the year-over-year impact of changes in foreign currency exchange rates.

Earnings per share impact							$	0.21

The most significant impacts were from larger losses in fiscal year 2016 from the revaluation of balance sheet assets and liabilities into the functional currencies of legal entities through which we operate globally presented as transaction losses within other income (expense), net, and a larger impact in fiscal year 2016 on our earnings from unconsolidated affiliates as results related to Líder were impacted by a 8.4% devaluation of the Brazilian real versus the U.S. dollar in fiscal year 2016. This favorable year-over-year change was partially offset by the unfavorable income statement translation impact from the depreciating British pound sterling due to Brexit on the translation of our results in our Europe Caspian region, partially offset by a favorable impact on our results of the devalued naira in our Africa region.

49

Direct costs decreased 10.1%, or $123.6 million, year-over-year primarily due to the benefit of organizational restructuring efforts reflected in a $63.4 million decrease in salaries and benefits resulting from lower headcount across all regions, a $7.0 million decrease in insurance expense, an $8.6 million decrease in inventory consignment fees and a $5.8 million decrease in training, travel and meals expense. Also, during fiscal year 2017, we determined the contingent consideration related to the Airnorth acquisition accrued in the purchase price was no longer probable of being paid out and we reversed $5.9 million of an accrued liability to direct costs. Additionally, bad debt expense decreased by $5.8 million primarily related to bad debt expense recorded in fiscal year 2016 related to two clients in our Africa region and a client in our Asia Pacific region.

Reimbursable expense decreased 38.5%, or $31.5 million, primarily due to a decline in activity and a contract amendment in our Europe Caspian region.

Depreciation and amortization decreased 13.2%, or $18.1 million, to $118.7 million for fiscal year 2017 from $136.8 million for fiscal year 2016. This decrease in depreciation and amortization expense is primarily due to a decrease in accelerated depreciation of $18.3 million as a result of fleet changes for older aircraft in fiscal year 2016, partially offset by an increase in depreciation expense due to additional aircraft and information technology costs being capitalized and depreciated in fiscal year 2017.

General and administrative expense decreased 13.0%, or $29.3 million, primarily due to a decrease of $8.8 million in salaries and benefits, a decrease of $6.3 million in professional fees and a decrease of $14.2 million in other general and administrative expenses, including information technology expenses, training, travel, recruitment and various other expenses from cost reduction initiatives. The reduction in salaries and benefits is primarily due to lower salaries and benefits of $13.8 million due to lower headcount in fiscal year 2017 from cost reduction initiatives, partially offset by higher management bonuses of $5.0 million in fiscal year 2017 due to no management bonuses being awarded in fiscal year 2016.

Loss on impairment for fiscal year 2017 included $8.7 million of goodwill impairment related to Eastern Airways and $7.6 million of inventory impairments. Loss on impairment for fiscal year 2016 included $41.6 million of goodwill impairment related to the Bristow Norway reporting unit and Eastern Airways within our Europe Caspian region ($25.2 million), Bristow Academy reporting unit within Corporate and other ($10.2 million) and the Africa reporting unit ($6.2 million), $8.1 million impairment of intangible assets of Eastern Airways and $5.4 million of inventory impairments.

Loss on disposal of assets decreased $16.2 million to a loss of $14.5 million for fiscal year 2017 from a loss of $30.7 million for fiscal year 2016. The loss on disposal of assets in fiscal year 2017 included impairment charges of $12.5 million related to 14 held for sale aircraft and a loss of $2.0 million from the sale of 14 aircraft and other equipment. During fiscal year 2016, the loss on disposal of assets included impairment charges of $29.6 million related to 16 held for sale aircraft and a loss of $1.1 million from the sale of 35 aircraft and other equipment.

Earnings from unconsolidated affiliates, net of losses, increased $6.7 million to earnings of $6.9 million for fiscal year 2017 from earnings of $0.3 million in fiscal year 2016. The increase primarily resulted from earnings from our investment in Líder in Brazil of $8.1 million for fiscal year 2017 compared to $0.1 million in losses in fiscal year 2016 primarily due to less of an unfavorable impact of foreign currency exchange rates, partially offset by a decline in activity. Our earnings from Líder in fiscal years 2017 and 2016 were reduced by the unfavorable impact of foreign currency exchange rate changes of $3.2 million and $22.4 million, respectively.

Interest expense, net, increased 46.3%, or $15.8 million, year-over-year primarily due to an increase in interest expense resulting from an increase in borrowings and an increase in amortization of debt fees.

Other income (expense), net decreased $1.6 million to other expense of $2.6 million for the fiscal year 2017 compared to other expense of $4.3 million for the fiscal year 2016 primarily due to lower foreign currency transaction losses in fiscal year 2017 compared to fiscal year 2016. For further details on other income (expense), net, see “— Region Operating Results — Other Income (Expense), Net” included elsewhere in this Annual Report.

For further details on income tax expense, see “— Region Operating Results — Taxes” included elsewhere in this Annual Report.

As discussed above, our results for fiscal year 2017 were impacted by a number of special items. In fiscal year 2016, special items that impacted our results included organizational restructuring costs, additional depreciation expense resulting from fleet changes, loss on impairment (including impairments of inventories, goodwill and intangible assets), tax items and accretion of redeemable noncontrolling interests. The items noted in fiscal years 2017 and 2016 have been identified as special items as they are not considered by management to be part of ongoing operations when assessing and measuring the operational and financial performance of the Company. The impact of these items on adjusted EBITDA, adjusted net income and adjusted diluted earnings per share is as follows:

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.

Fiscal Year 2018 Compared to Fiscal Year 2017

The increase in operating revenue in fiscal year 2018 primarily resulted from an increase in Norway of $35.6 million, primarily due to an increase in activity and short-term contracts, an increase of $33.4 million from the start-up of U.K. SAR bases, a favorable year-over-year impact of changes in foreign currency exchange rates of $11.4 million and an increase in fixed wing revenue of $8.1 million. Partially offsetting these increases was a decrease in U.K. oil and gas revenue of $33.8 million resulting from the continued impact of the industry downturn on drilling activity. Eastern Airways contributed $118.5 million and $110.4 million in operating revenue for fiscal years 2018 and 2017, respectively.

During fiscal year 2018, we recorded a reduction to rent expense of $9.9 million in our Europe Caspian region related to OEM cost recoveries. This item is included in operating income and adjusted EBITDA in fiscal year 2018. During fiscal year 2018, we recorded inventory impairment charges of $4.5 million for our fixed wing operations at Eastern Airways as a result of changes in expected future utilization of aircraft within those operations. These charges were recorded as a direct reduction in the value of spare parts inventory to record them at net realizable value. Additionally, during fiscal year 2017, we recorded an impairment charge of $8.7 million for the remaining goodwill related to Eastern Airways. Both the inventory and goodwill impairments are included in operating income, but were adjusted for in our calculation of adjusted EBITDA. For further details, see Notes 1 and 3 in the “Notes to Consolidated Financial Statements” included elsewhere in this Annual Report. Also, we recorded severance expense related to organizational restructuring efforts of $1.9 million and $1.4 million for fiscal years 2018 and 2017, respectively, which is excluded from adjusted EBITDA and adjusted EBITDA margin.

A substantial portion of our revenue in the Europe Caspian region is contracted in the British pound sterling, which depreciated significantly against the U.S. dollar in fiscal year 2017 as a result of Brexit. We recorded a foreign exchange gains of $4.3 million in fiscal year 2018 and foreign exchange losses of $18.5 million in fiscal year 2017 from the revaluation of assets and liabilities on British pound sterling functional currency entities as of March 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 positively impacted by $9.2 million and negatively impacted by $35.6 million resulting from the changes in exchange rates during fiscal years 2018 and 2017, respectively. A further weakening or strengthening of the British pound sterling could result in additional foreign exchange volatility in future periods.

52

Operating income, operating margin, adjusted EBITDA and adjusted EBITDA margin increased in fiscal year 2018 primarily due to the increase in operating revenue, the benefit to rent expense in fiscal year 2018 related to OEM cost recoveries and the impact of favorable changes in foreign currency exchange rates. These benefits were partially offset by increased salaries and benefits and maintenance expense year-over-year due to the increase in activity. Eastern Airways contributed a negative $6.9 million and negative $4.5 million in adjusted EBITDA for fiscal years 2018 and 2017, respectively.

Fiscal Year 2017 Compared to Fiscal Year 2016

The year-over-year decrease in operating revenue primarily resulted from the impact of changes in foreign currency exchange rates which reduced operating revenue by $79.4 million, decreased activity levels with our oil and gas clients due to the downturn in the industry which reduced operating revenue by $28.1 million, and the end of an oil and gas contract that began in late fiscal year 2015 and ended in late fiscal year 2016 that contributed $51.3 million in additional operating revenue in fiscal year 2016. Partially offsetting these decreases was an increase in operating revenue (on a foreign exchange neutral basis) from the start-up of U.K. SAR bases of $41.5 million. Eastern Airways contributed $110.4 million and $133.5 million in operating revenue and negative $4.5 million and positive $13.6 million in adjusted EBITDA for fiscal years 2017 and 2016, respectively.

The movement of exchange rates decreased operating revenue, operating income and adjusted EBITDA by $79.4 million, $26.7 million and $35.1 million, respectively, from translation of results compared to fiscal year 2016. Additionally, we recorded foreign exchange losses of $18.5 million and $11.1 million as of March 31, 2017 and 2016, respectively, from the revaluation of assets and liabilities on British pound sterling functional currency entities which is recorded in other income (expense), net and included in adjusted EBITDA. Including both the translation and revaluation impacts, adjusted EBITDA was reduced by $35.1 million and $9.0 million during fiscal year 2017 and 2016, respectively, resulting from changes in foreign exchange rates.

Additionally, during fiscal year 2017, we recorded an impairment of $8.7 million for the remaining goodwill related to Eastern Airways. During fiscal year 2016, we recorded impairments of goodwill and intangibles of $21.2 million relating to Eastern Airways and impairment of goodwill for operations in Norway of $12.1 million. These impairment charges contributed to a portion of the decline in operating income in fiscal years 2017 and 2016, but were adjusted for in our calculation of adjusted EBITDA. For additional details on the impairment of goodwill and intangibles, see Note 1 in the “Notes to Consolidated Financial Statements” included elsewhere in this Annual Report.

The decrease in operating margin and adjusted EBITDA margin is primarily a result of the impact from the downturn in the offshore energy industry, which was only partially offset by the start-up of the U.K. SAR bases and cost reduction activities.

Fiscal Year 2018 Compared to Fiscal Year 2017

Operating revenue for Africa decreased in fiscal year 2018 primarily due to an overall decrease in activity compared to fiscal year 2017. Activity declined with certain clients and certain contracts ended, reducing revenue by $17.0 million, which was only partially offset by an increase in activity with other clients increasing revenue by $5.5 million. Additionally, fixed wing services in Africa generated $7.4 million and $4.2 million of operating revenue for fiscal years 2018 and 2017, respectively.

Operating income, operating margin, adjusted EBITDA and adjusted EBITDA margin increased in fiscal year 2018 primarily due to a $7.3 million decline in direct costs, partially offset by the decrease in revenue discussed above. Additionally, operating income and operating margin improved in fiscal year 2018 due to lower depreciation expense. During fiscal year 2017, we recorded $6.0 million of accelerated depreciation expense related to aircraft where management made the decision to exit these model types earlier than originally anticipated. The year-over-year devaluation of the Nigerian naira also benefited adjusted EBITDA by $1.4 million compared to fiscal year 2017 as expenses denominated in Nigerian naira translated into less U.S. dollars for reporting purposes.

During fiscal years 2018 and 2017, we recorded $8.0 million and $4.5 million, respectively, in severance expense resulting from voluntary and involuntary separation programs as part of our restructuring efforts, which is excluded from adjusted EBITDA and adjusted EBITDA margin.

On March 31, 2018, a significant contract in this region expired and was not renewed. Additionally, changing regulations and political environment have made, and are expected to continue to make, our operating results for Nigeria unpredictable. Market uncertainty related to the oil and gas downturn has continued in this region, putting smaller clients under increasing pressure as their activity declined, which reduced our activity levels and overall pricing. Although we continue to implement cost reduction measures, we currently expect the financial results for this region to decline in fiscal year 2019.

Fiscal Year2017Compared to Fiscal Year2016

Operating revenue for Africa decreased in fiscal year 2017 primarily due to an overall decrease in activity resulting from the downturn of the oil and gas industry. The decreased activity levels reduced revenue by $59.7 million, which was only partially offset by $7.5 million from new contracts and increased activity on a contract. Additionally, Eastern Airways began providing fixed wing services in Africa in October 2015, which generated $4.2 million and $0.2 million of operating revenue for fiscal years 2017 and 2016, respectively. A majority of our revenue in our Africa region is contracted at fixed U.S. dollar rates, resulting in minimal exposure to the devalued Nigerian naira upon translation into U.S. dollars for reporting purposes.

Operating income and operating margin for the Africa region were significantly impacted by an impairment of goodwill of $6.2 million during fiscal year 2016, which resulted from lower forecasted results for future periods due to the ongoing oil and gas industry downturn. For additional details on the impairment of goodwill, see Note 1 in the “Notes to Consolidated Financial Statements” included elsewhere in this Annual Report.

Operating income, operating margin and adjusted EBITDA margin increased in fiscal year 2017 primarily due to a $35.8 million decrease in direct costs and a $7.5 million decrease in general and administrative expenses, partially offset by the decrease in revenue discussed above. Operating expenses were $17.7 million lower in fiscal year 2017 due to the devaluation of the Nigerian naira which resulted in naira-based expenses translating into fewer U.S. dollars. Also, during fiscal year 2016, we recorded $4.7 million in bad debt expense related to two clients in this region. Operating income and operating margin in fiscal year 2017 also benefited from a decrease in depreciation and amortization expense as a result of a lower amount of accelerated depreciation of $6.0 million versus $16.8 million in fiscal year 2016. Adjusted EBITDA declined as the impact to decreased revenue was only partially offset by cost reduction activities and the favorable exchange rate impact in fiscal year 2017 compared to fiscal year 2016.

During fiscal years 2017 and 2016, we recorded $4.5 million and $5.2 million, respectively, in severance expense resulting from voluntary and involuntary separation programs as part of our restructuring efforts, which is excluded from adjusted EBITDA and adjusted EBITDA margin.

The increase of operating margin and adjusted EBITDA margin is primarily related to the reduction of operating expense due to the devaluation of the Nigerian naira and cost reduction activities, partially offset by the reduction in revenue due to the downturn of the oil and gas industry.

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.

Fiscal Year 2018 Compared to Fiscal Year 2017

Operating revenue increased in fiscal year 2018 primarily due to an increase in activity in our U.S. Gulf of Mexico oil and gas operations, which increased operating revenue by $11.8 million and $8.1 million in additional operating revenue from the SAR consortium in the U.S. Gulf of Mexico, partially offset by a decrease of $4.4 million in operating revenue in Trinidad due to lower activity.

Earnings from unconsolidated affiliates, net of losses, decreased $0.9 million in fiscal year 2018 primarily due to a decrease in earnings from our investment in Líder in Brazil resulting from a decrease in activity, partially offset by less of an unfavorable impact of foreign currency exchange rates. Operating income, operating margin, adjusted EBITDA and adjusted EBITDA margin were negatively impacted by unfavorable foreign currency exchange rate changes, which decreased our earnings from our investment in Líder by $2.0 million in fiscal year 2018 and $3.2 million in fiscal year 2017. During fiscal year 2018, we recorded an $85.7 million impairment of our investment in Líder, which impacted operating income and operating margin, but is excluded from the calculation of adjusted EBITDA and adjusted EBITDA margin. See further discussion about our investment in Líder and the Brazil market in “— Executive Overview — Market Outlook” included elsewhere in this Annual Report.

The decreases in operating income and operating margin resulted from the impairment of our investment in Líder as discussed above. The increase in adjusted EBITDA resulted primarily from the increase in revenue discussed above, partially offset by an increase in maintenance expense of $8.2 million primarily due to an increase in activity, the decrease in earnings from unconsolidated affiliates discussed above and an increase in rent expense of $1.9 million primarily due to an increase in number of leased aircraft. During fiscal year 2017, we recorded accelerated depreciation expense on aircraft exiting our fleet of $3.9 million. Additionally, we recorded severance expense related to organizational restructuring efforts of $0.4 million and $1.2 million for fiscal years 2018 and 2017, respectively. Depreciation and amortization, including accelerated depreciation, and severance expense recorded in fiscal years 2018 and 2017, were excluded from adjusted EBITDA and adjusted EBITDA margin. The decrease in adjusted EBITDA margin is primarily due to the decrease in earnings from unconsolidated affiliates and the increase in rent expense, partially offset by the increase in revenue.

Fiscal Year 2017 Compared to Fiscal Year 2016

Operating revenue decreased in fiscal year 2017 primarily due to a decline in activity in our U.S. Gulf of Mexico operations resulting from the oil and gas industry downturn that reduced operating revenue by $64.6 million, a decrease of $7.5 million in Brazil due to fewer aircraft leased to Líder and a decrease in Suriname of $5.2 million due to the end of a contract. These decreases were partially offset by a new contract in Guyana, which increased operating revenue by $6.5 million.

55

Operating income, operating margin, adjusted EBITDA and adjusted EBITDA margin were negatively impacted by unfavorable exchange rate changes in fiscal years 2017 and 2016, which reduced our earnings from our investment in Líder by $3.2 million and $22.4 million in fiscal year 2017 and 2016, respectively. Excluding this impact, in fiscal year 2017 and 2016, earnings from our investment in Líder would have been $11.3 million and $22.3 million, respectively, operating income for the Americas region would have been $7.3 million (3.3% operating margin) and $56.9 million (19.6% operating margin), respectively, and adjusted EBITDA for the Americas region would have been $43.1 million (19.6% adjusted EBITDA margin) and $94.4 million (32.5% adjusted EBITDA margin), respectively. This year-over-year decrease in the Americas region’s operating income, operating margin, adjusted EBITDA and adjusted EBITDA margin primarily resulted from a decline in revenue due to the decline in activity discussed above and reduced pre-foreign exchange earnings from our investment in Líder, partially offset by a decrease in direct costs, including an $11.2 million decrease in maintenance expense and an $8.0 million decrease in salaries and benefits due to cost reduction initiatives.

During fiscal years 2017 and 2016, we recorded accelerated depreciation expense on aircraft exiting our fleet of $3.9 million and $6.0 million, respectively, and we recorded severance expense related to organizational restructuring efforts of $1.2 million and $2.1 million, respectively. Depreciation and amortization, including accelerated depreciation, and severance expense recorded during fiscal years 2017 and 2016 were excluded from adjusted EBITDA and adjusted EBITDA margin.

The Asia Pacific region comprises all our operations and affiliates in Australia and Asia, including Malaysia, Sakhalin, and our fixed wing operations through Airnorth in Australia.

Fiscal Year 2018 Compared to Fiscal Year 2017

Operating revenue decreased in fiscal year 2018 primarily due to $17.2 million of operating revenue earned upon cancellation of a contract in fiscal year 2017 that did not recur in fiscal year 2018 (see discussion below) and the ending of short-term oil and gas contracts in Australia resulting in a decrease in operating revenue of $15.9 million, partially offset by an increase of $6.7 million from our fixed wing operations at Airnorth, an increase of $5.0 million in Sakhalin and a favorable foreign currency exchange rate impact of $4.8 million. Airnorth contributed $83.8 million and $77.1 million, respectively, in operating revenue for fiscal years 2018 and 2017, respectively.

During March 2017, we came to an agreement with a client for which we had incurred significant start-up costs on a project in Australia that was cancelled prior to contract commencement. In connection with the cancellation, we agreed to a termination fee with the client of $11.1 million, which is recorded in operating revenue in fiscal year 2017, and contributed $11.1 million in operating income and adjusted EBITDA in fiscal year 2017. Additionally, we had previously deferred revenue and costs of $6.1 million each related to this contract, which are included in operating revenue and direct costs in fiscal year 2017.

56

Operating income and operating margin decreased primarily due to decreased activity, which was only partially offset by a decrease in direct costs, including a decrease of $8.1 million in salaries and benefits and a reduction in rent expense of $6.7 million related to OEM cost recoveries. Additionally, operating income and operating margin benefited in fiscal year 2017 from the contract cancellation billing in March 2017 discussed above. During fiscal years 2018 and 2017, we recorded $3.9 million and $2.9 million, respectively, in severance expense related to organizational restructuring activities. The severance expense is not included in adjusted EBITDA or adjusted EBITDA margin for fiscal years 2018 and 2017. Also, during fiscal year 2017, we determined the contingent consideration related to Airnorth acquisition accrued in the purchase price was no longer probable of being paid out and we reversed $5.9 million of an accrued liability to direct costs. The reversal of this contingent consideration is not included in adjusted EBITDA for fiscal year 2017. Adjusted EBITDA and adjusted EBITDA margin improved primarily due the reduction in salaries and benefits and rent expense discussed above, partially offset by the termination fee of $11.1 million recorded in fiscal year 2017. Airnorth contributed $7.2 million and $7.1 million in adjusted EBITDA in fiscal years 2018 and 2017, respectively.

Fiscal Year 2017 Compared to Fiscal Year 2016

Operating revenue decreased in fiscal year 2017 by $72.3 million primarily due to the ending of short-term oil and gas contracts in Australia and a $4.3 million decrease due to a short-term contract in South Korea in fiscal year 2016, partially offset by additional operating revenue of $17.2 million earned upon cancellation of a contract in fiscal year 2017 (see discussion above) and a $1.7 million increase for Airnorth. A significant portion of our revenue in the Asia Pacific region is contracted in the Australian dollar, which strengthened against the U.S. dollar in fiscal year 2017, resulting in an increase in revenue of $3.4 million year-over-year. Airnorth contributed $77.1 million and $75.4 million, respectively, in operating revenue and $7.1 million and $12.4 million, respectively, in adjusted EBITDA for fiscal years 2017 and 2016.

Operating income, operating margin, adjusted EBITDA and adjusted EBITDA margin decreased primarily due to decreased activity which was only partially offset by a decrease in direct costs, including a decrease of $7.7 million in salaries and benefits and a decrease of $9.4 million in maintenance expense, and the contract cancellation billing in March 2017. During fiscal year 2016, we recorded additional depreciation expense of $5.3 million for four large aircraft operating in this region due to management’s decision to exit these fleet types earlier than originally anticipated, and during fiscal years 2017 and 2016, we recorded $2.9 million and $2.3 million, respectively, in severance expense related to organizational restructuring activities. The severance expense is not included in adjusted EBITDA or adjusted EBITDA margin for fiscal years 2017 and 2016. Also, during fiscal year 2017, we determined the contingent consideration related to Airnorth acquisition accrued in the purchase price was no longer probable of being paid out and we reversed $5.9 million of an accrued liability to direct costs. The reversal of this continent consideration is not included in adjusted EBITDA for fiscal year 2017.

Fiscal Year 2018 Compared to Fiscal Year 2017

Operating revenue decreased in fiscal year 2018 primarily due to a decline in Bristow Academy revenue of $3.8 million and decrease in third-party part sales of $2.3 million.

Operating loss for fiscal years 2018 and 2017 were most significantly impacted by $1.2 million and $7.6 million, respectively, of inventory impairment charges and a $9.3 million reduction in general and administrative expenses primarily due to reduction in headcount and the sale of Bristow Academy, partially offset by the decline in revenue discussed above. Adjusted EBITDA decreased primarily due to foreign currency transaction losses of $4.4 million for fiscal year 2018 versus foreign currency transaction gains of $14.5 million for fiscal year 2017. The change in foreign currency impacts was partially offset by overall cost reduction activities that decreased general and administrative expenses as discussed above.

During fiscal years 2018 and 2017, we recorded $9.5 million and $10.9 million related to organizational restructuring costs, respectively, which, along with the inventory impairment charges discussed above, are excluded from adjusted EBITDA.

Fiscal Year 2017 Compared to Fiscal Year 2016

Operating revenue decreased in fiscal year 2017 primarily due to a decline in Bristow Academy revenue of $9.7 million due to a decline in military training and a decrease in third-party part sales of $3.1 million.

Operating loss and adjusted EBITDA improved in fiscal year 2017 primarily due to cost reduction activities that lowered general and administrative costs, including a reduction in salaries and benefits of $4.8 million, professional fees of $5.1 million and other costs of $4.5 million, partially offset by a decline in revenue discussed above. Additionally, fiscal year 2016 operating loss included the impairment of goodwill for Bristow Academy of $10.2 million. Also, in fiscal year 2017, adjusted EBITDA benefited from the favorable impact of changes in foreign currency exchange rates on our Corporate results of $10.9 million compared to fiscal year 2016.

During fiscal years 2017 and 2016, we recorded $10.9 million and $7.7 million, respectively, related to organizational restructuring costs, and fiscal years 2017 and 2016 include $7.6 million and $5.4 million, respectively, of inventory impairments, and fiscal year 2016 includes the impairment of $10.2 million of Bristow Academy’s goodwill, all of which are included in operating loss and excluded from adjusted EBITDA.

Gain (loss) on disposal of assets

The loss on disposal of assets in fiscal year 2018 included impairment charges of $8.7 million related to eight held for sale aircraft, losses of $1.7 million from the sale or disposal of 11 aircraft and other equipment and $7.2 million impairment and loss on disposal related to the Bristow Academy disposal group. The loss on disposal of assets in fiscal year 2017 included impairment charges of $12.5 million related to 14 held for sale aircraft and losses of $2.0 million from the sale or disposal of 14 aircraft and other equipment. The loss on disposal of assets in fiscal year 2016 included impairment charges of $29.6 million related to 16 held for sale aircraft, partially offset by gains of $1.1 million from the sale of 35 aircraft and other equipment.

Interest expense, net increased in fiscal year 2018 compared to fiscal year 2017 primarily due to an increase in borrowings at higher borrowing rates and lower capitalized interest resulting from lower average construction in progress. Additionally, during fiscal year 2018, we wrote-off $3.0 million of deferred financing fees related to the early extinguishment of debt. Interest expense, net increased in fiscal year 2017 compared to fiscal year 2016 primarily due to an increase in borrowings and an increase in amortization of debt fees.

Other income (expense), net for the periods presented above 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. Additionally, during the fiscal year 2018, we recorded a provision related to a non-operational contract matter with a client.

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 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.

⁽¹⁾  The effective tax rate for fiscal year 2017 represents income tax expense rate on a pre-tax net loss for the fiscal year. Due to pre-tax losses for fiscal years 2018 and 2016, the effective tax rates for those fiscal years represent the income tax benefit rate recorded for the periods.

A portion of our aircraft fleet is owned directly or indirectly by our wholly owned Cayman Island subsidiaries. Our foreign operations combined with our leasing structure provided a material benefit to the effective tax rates for fiscal years 2018, 2017 and 2016. In fiscal year 2017, our unfavorable permanent differences, such as valuation allowances and non-tax deductible goodwill write-off had the effect of increasing our income tax expense and reducing our effective tax rate applied to pre-tax losses. Also, our effective tax rates for fiscal years 2018, 2017 and 2016 benefited from the permanent investment outside the U.S. of foreign earnings, upon which no U.S. tax had been provided until the deemed repatriation of foreign earnings under the Act.

Fiscal Year 2018 Compared to Fiscal Year 2017

Our effective income tax rate for fiscal year 2018 is 13.5%, which includes a $53.0 million benefit related to the revaluation of net deferred tax liabilities to a lower tax rate as a result of the Act and net reversal of valuation allowances on deferred tax assets of $2.6 million. This benefit was partially offset by the impact of the one-time transition tax on the repatriation of foreign earnings under the Act of $30.3 million and a one-time non-cash tax expense of $42.5 million due to the repositioning of certain aircraft from one tax jurisdiction to another related to recent financing transactions.

Fiscal Year 2017 Compared to Fiscal Year 2016

Our effective income tax rate for fiscal year 2017 is (22.6)% representing the income tax expense rate on a pre-tax net loss for the fiscal year, which includes $37.0 million of tax expense for an increase in valuation allowance, a one-time non-cash tax effect from repositioning of certain aircraft from one tax jurisdiction to another related to recent financing transactions resulting in additional income tax expense of $22.5 million, $0.2 million of tax expense due to the revaluation of our deferred taxes as a result of the enactment of a tax rate reduction in the U.K. and Norway and $3.5 million tax benefit due to the deduction of foreign tax in lieu of foreign tax credits. Our effective income tax rate for fiscal year 2016 is 2.6% representing the income tax benefit rate for the fiscal year, which was reduced by $20.1 million of tax expense for an increase in valuation allowance and increased by $0.9 million of tax benefit due to the revaluation of our deferred taxes as a result of the enactment of a tax rate reduction in the U.K. and a $2.1 million tax benefit due to the deduction of foreign tax in lieu of foreign tax credits.

Noncontrolling Interest

Net loss attributable to noncontrolling interest decreased to $2.4 million for fiscal year 2018 compared to $6.4 million for fiscal year 2017 primarily due to higher earnings from Eastern Airways during fiscal year 2018 compared to fiscal year 2017. Net loss attributable to noncontrolling interests increased to $6.4 million for fiscal year 2017 compared to $4.7 million for fiscal year 2016 due to lower earnings from Eastern Airways during fiscal year 2017 compared to fiscal year 2016.

Liquidity and Capital Resources

Cash Flows

Operating Activities

Net cash used in operating activities was $19.5 million during fiscal year 2018 and net cash provided by operating activities was $11.5 million and $118.2 million during fiscal years 2017 and 2016, respectively. Changes in non-cash working capital used $20.0 million in cash flows during fiscal year 2018, and generated $18.4 million and $23.0 million in cash flows during fiscal years 2017 and 2016, respectively. The decline in cash flows from operations for fiscal year 2018 compared to fiscal year 2017 is primarily due to the change in non-cash working capital. Cash flows used by operating activities for fiscal year 2018 includes proceeds of $30.5 million related to OEM cost recoveries, of which $22.4 million is included in cash flows from operations before working capital changes and $8.1 million is included in working capital changes, which was partially offset by cash payments of $19.8 million for cash collateralization of letters of credit included in working capital changes. Cash flows provided by operating activities decreased in fiscal year 2017 compared to fiscal year 2016 due to the decreased earnings that resulted from the decline in oil and gas activity across all regions.

Investing Activities

Cash flows provided by investing activities were $96.9 million for fiscal year 2018 and cash flows used in investing activities were $116.3 million and $316.8 million for fiscal years 2017 and 2016, respectively. Cash was used primarily for capital expenditures as follows:

	Fiscal Year Ended March 31,
	2018		2017		2016
Number of aircraft delivered:
Medium	5		5		1
Large	—		—		3
SAR aircraft	—		4		4

Other	13,869		7,663		86,845
Total capital expenditures	$	46,287	$	135,110	$	372,375

In addition to these capital expenditures, investing cash flows were impacted by the following items during the last three fiscal years:

Fiscal Year 2018 — During fiscal year 2018, we received proceeds of $48.7 million primarily from the sale or disposal of 11 aircraft and certain other equipment. Also, during fiscal year 2018, cash flows from investing activities includes $94.5 million related to OEM cost recoveries.

Fiscal Year 2017 — During fiscal year 2017, we received proceeds of $18.5 million primarily from the sale or disposal of 14 aircraft and certain other equipment.

Fiscal Year 2016 — During fiscal year 2016, we received $30.8 million in proceeds primarily from the sale or disposal of 32 aircraft and certain other equipment (including $13.4 million in insurance recoveries) and $29.2 million from the sale of three aircraft, which we subsequently leased back.

Financing Activities

We generated cash flows from financing activities of $189.0 million, $106.7 million and $189.4 million during fiscal years 2018, 2017 and 2016, respectively.

61

During fiscal year 2018, we received $174.8 million from borrowings on our Revolving Credit Facility, $230 million from borrowings on our PK Air Debt, $143.8 million from the sale of our 4½% Convertible Senior Notes and $346.6 million from the sale of our 8.75% Senior Secured Notes. During fiscal year 2018, we used cash to repay debt of $671.6 million and pay dividends of $2.5 million on our common stock. Additionally, during fiscal year 2018, we paid $40.4 million for the purchase of the 4½% Convertible Senior Notes call option, and simultaneously received $30.3 million for the issuance of warrants.

During fiscal year 2017, we received $300.6 million from borrowings on our Revolving Credit Facility, $200 million from the Lombard Debt and $200 million from the Macquarie Debt. During fiscal year 2017, we used cash to repay debt of $570.3 million and pay dividends of $9.8 million on our common stock.

During fiscal year 2016, we received $580.9 million from borrowings on our Revolving Credit Facility, $200 million from borrowings on our Term Loan Credit Facility and $127.4 million from borrowings on our Term Loan. During fiscal year 2016, we used cash to repay debt of $677.0 million and pay dividends of $38.1 million on our common stock.

Future Cash Requirements

Debt Obligations

Total debt (excluding unamortized discounts and debt issuance costs) as of March 31, 2018 was $1.6 billion, of which substantially all was classified as current. The following table summarizes the contractual maturity dates for our significant debt as of March 31, 2018 and does not reflect the impact of the Chapter 11 Cases:

Debt	Maturity Date
Macquarie Debt	March 7, 2022
6 ¼% Senior Notes	October 15, 2022
8.75% Senior Secured Notes	March 1, 2023 (1)
4½% Convertible Senior Notes	June 1, 2023
PK Air Debt	July 13 and 27, 2023
Lombard Debt	December 29, 2023 and January 23, 2024

_______________

⁽¹⁾  The 8.75% Senior Secured Notes will mature on March 1, 2023, subject to earlier mandatory redemption if more than $125 million principal amount of the 6¼% Senior Notes plus the principal amount of any indebtedness incurred to refinance the 6¼% Senior Notes that matures or is required to be repaid prior to June 1, 2023 remains outstanding as of June 30, 2022. For further details, see Note 4 in the “Notes to Consolidated Financial Statements” included elsewhere in this Annual Report.

On April 17, 2018, two of our subsidiaries entered into a new 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 five years, subject to certain early maturity triggers related to maturity of other material debt or a change of control of the Company. For further details, see Note 4 in the “Notes to Consolidated Financial Statements” included elsewhere in this Annual Report.

See further discussion of outstanding debt as of March 31, 2018 and our debt issuances and our debt redemptions in Note 4 in the “Notes to Consolidated Financial Statements” included elsewhere in this Annual Report.

Pension Obligations

As of March 31, 2018, we had recorded on our balance sheet a net $36.8 million pension liability related to the Bristow Helicopters Limited and Bristow International Aviation (Guernsey) Limited (“BIAGL”) pension plans. The liability represents the excess of the present value of the defined benefit pension plan liabilities over the fair value of plan assets that existed at that date. The minimum funding rules of the U.K. require the employer to agree to a funding plan with the plans’ trustee for securing that the pension plan has sufficient and appropriate assets to meet its technical provisions liabilities. In addition, where there is a shortfall in assets against this measure, we are required to make scheduled contributions in amounts sufficient to bring the plan up to 100% funded as quickly as can be reasonably afforded. The employer contributions for the main U.K. pension plan for fiscal years 2018, 2017 and 2016 were £12.8 million ($17.0 million), £12.4 million ($15.5 million), and £12.4 million ($17.8 million), respectively. See further discussion of our pension plans in Note 9 in the “Notes to Consolidated Financial Statements” included elsewhere in this Annual Report.

Contractual Obligations, Commercial Commitments and Off Balance Sheet Arrangements

We have various contractual obligations that are recorded as liabilities on our consolidated balance sheet. Other items, such as certain purchase commitments, interest payments and other executory contracts are not recognized as liabilities on our 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 March 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 March 31, 2018 based on the contractual terms and has not been amended to reclassify substantially all of our long-term debt as current for any possible accelerations as discussed in the Explanatory Note included elsewhere in this Annual Report. Additional details regarding these obligations are provided in Notes 4, 5, 7 and 9 in the “Notes to Consolidated Financial Statements” included elsewhere in this Annual Report.

⁽¹⁾  Excludes unamortized discounts of $39.8 million and unamortized debt issuance cost of $27.5 million.

⁽²⁾  Interest payments for variable rate interest debt are based on interest rates as of March 31, 2018.

⁽³⁾  Represents separate operating leases for aircraft.

⁽⁴⁾  Represents minimum rental payments required under non-aircraft operating leases that have initial or remaining non-cancelable lease terms in excess of one year.

⁽⁵⁾  Represents expected funding for pension benefits in future periods. These amounts are undiscounted and are based on the expectation that the U.K. pension plan will be fully funded in approximately four years. As of March 31, 2018, we had recorded on our balance sheet a net $36.8 million pension liability associated with these obligations. The timing of the funding is dependent on actuarial valuations and resulting negotiations with the plan trustees.

⁽⁶⁾  Includes $4.4 million for final payments for aircraft delivered during fiscal year 2018 that is included in accounts payable as of March 31, 2018.

⁽⁷⁾  Includes $98.0 million for five aircraft orders that can be cancelled prior to delivery dates. As of March 31, 2018, we made non-refundable deposits of $4.5 million related to these aircraft.

⁽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 elsewhere in this Annual Report. In connection with the Bristow Norway acquisition in October 2008, we granted the former partner in this joint venture an option that if exercised would require us to acquire up to five aircraft at fair value upon the expiration of the lease terms for such aircraft. One of the options was exercised in December 2009 and two of the options expired. The remaining aircraft leases expire in August 2018. We are currently unable to estimate the fair value of these aircraft; therefore, the table above does not include any amounts relating to this potential commitment. While we do not currently expect to be required to purchase these aircraft, the former joint venture partner has until May 31, 2018 to notify us. If the joint venture partner does not exercise its option, it is our intent to return the aircraft after the leases expire in August 2018.

63

⁽⁹⁾  As of March 31, 2018, we had outstanding letters of credit that we had collateralized with certificates of deposit totaling $19.8 million included in accounts receivable from non-affiliates on our consolidated balance sheets.

⁽¹⁰⁾  Includes $3.1 million related to Airnorth. The Airnorth purchase agreement includes a potential earn-out of A$17 million ($13.0 million) to be paid over four years. During fiscal year 2016, a portion of the first year earn-out payment of A$2 million ($1.5 million) was paid as Airnorth achieved agreed performance targets. The second and third year earn-out performance targets were not met. The remaining Airnorth earn-out, which is contingent upon both the achievement of agreed performance targets and the continued employment of the selling shareholders, will be included as general and administrative expense in our consolidated statements of operations as earned. The earn-out for Airnorth is remeasured to fair value at each reporting date until the contingency is resolved and any changes in estimated fair value are recorded as accretion expense included in interest expense on our consolidated statements of operations.

⁽¹⁾  Total debt excludes unamortized debt issuance costs.

⁽²⁾  The Revolving Credit Facility was terminated on March 6, 2018. For further details, see Note 4 in the “Notes to Consolidated Financial Statements” included elsewhere in this Annual Report.

⁽³⁾  On April 17, 2018, two of our subsidiaries entered into a new ABL Facility, which provides for commitments in an aggregate amount of up to $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. For further details, see Note 4 in the “Notes to Consolidated Financial Statements” included elsewhere in this Annual Report.

⁽⁴⁾  As of March 31, 2018 and 2017, adjusted debt includes balance sheet debt of $1.5 billion and $1.3 billion, respectively, excluding unamortized debt issuance costs, the net present value of operating leases of $388.3 million and $520.0 million, respectively, letters of credit, bank guarantees and financial guarantees of $22.1 million and $12.0 million, respectively, and the net unfunded pension liability of $36.8 million and $61.6 million, respectively. Adjusted debt to equity ratio is a non-GAAP financial measure that management believes provides meaningful supplemental information regarding our financial position.

We manage our liquidity through generation of cash from operations while assessing our funding needs on an ongoing basis. Historically, while we have generated cash from operations, financing cash flows also have been a significant source of liquidity over the past several years. 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.

64

As of March 31, 2018, approximately 25% 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 changed since the date of the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2018, originally filed with the SEC on May 23, 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 Annual Report, 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”) 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. Each of the commencement of the Chapter 11 Cases and the delivery of this Annual Report on Form 10-K for the fiscal year ended March 31, 2018, as amended by the amendment thereto (this “Amended 10-K”), 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 should be reclassified from long-term to short-term as of March 31, 2018 within this Amended 10-K on our consolidated balance sheet.

Exposure to Currency Fluctuations

See our discussion of the impact of market risk, including our exposure to currency fluctuations, on our financial position and results of operations discussed under Item 7A. “Quantitative and Qualitative Disclosures about Market Risk” included elsewhere in this Annual Report.

Critical Accounting Policies and Estimates

Our consolidated financial statements have been prepared in accordance with U.S. GAAP. In many cases, the accounting treatment of a particular transaction is specifically dictated by U.S. GAAP, whereas, in other circumstances, U.S. GAAP requires us to make estimates, judgments and assumptions that we believe are reasonable based upon information available. We base our estimates and judgments on historical experience, professional advice and various other sources that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions and conditions. We believe that of our significant accounting policies, as discussed in Note 1 in the “Notes to Consolidated Financial Statements” included elsewhere in this Annual Report, the following involve a higher degree of judgment and complexity. Our management has discussed the development and selection of critical accounting policies and estimates with the Audit Committee of our board of directors and the Audit Committee has reviewed our disclosure.

Taxes

Our annual tax provision is based on expected taxable income, statutory rates and tax planning opportunities available to us in the various jurisdictions in which we operate. The determination and evaluation of our annual tax provision and tax positions involves the interpretation of the tax laws in the various jurisdictions in which we operate and requires significant judgment and the use of estimates and assumptions regarding significant future events such as the amount, timing and character of income, deductions and tax credits. Changes in tax laws, regulations, agreements, tax treaties and foreign currency exchange restrictions or our level of operations or profitability in each jurisdiction would impact our tax liability in any given year. We also operate in many jurisdictions where the tax laws relating to the offshore oil service industry are open to interpretation which could potentially result in tax authorities asserting additional tax liabilities. While our annual tax provision is based on the best information available at the time, a number of years may elapse before the ultimate tax liabilities in the various jurisdictions are determined.

65

We recognize foreign tax credits available to us to offset the U.S. income taxes due on income earned from foreign sources. These credits are limited by the total income tax on the U.S. income tax return as well as by the ratio of foreign source income in each statutory category to total income. In estimating the amount of foreign tax credits that are realizable, we estimate future taxable income in each statutory category. These estimates are subject to change based on changes in the market conditions in each statutory category and the timing of certain deductions available to us in each statutory category. We periodically reassess these estimates and record changes to the amount of realizable foreign tax credits based on these revised estimates. Changes to the amount of realizable foreign tax credits can be significant given any material change to our estimates on which the realizability of foreign tax credits is based.

66

We maintain reserves for estimated income tax exposures in jurisdictions of operation. The expenses reported for these taxes, including our annual tax provision, include the effect of reserve provisions and changes to reserves that we consider appropriate, as well as related interest. Tax exposure items primarily include potential challenges to intercompany pricing, disposition transactions and the applicability or rate of various withholding taxes. These exposures are resolved primarily through the settlement of audits within these tax jurisdictions or by judicial means, but can also be affected by changes in applicable tax law or other factors, which could cause us to conclude that a revision of past estimates is appropriate. We believe that an appropriate liability has been established for estimated exposures. However, actual results may differ materially from these estimates. We review these liabilities quarterly. During fiscal years 2018, 2017 and 2016, we had accruals and releases of reserves for estimated tax exposures of $5.4 million, $0.2 million and $0.4 million, respectively. We recognize interest and penalties accrued related to unrecognized tax benefits as a component of our provision for income taxes. As of March 31, 2018 and 2017, we had $6.7 million and $1.3 million, respectively, of unrecognized tax benefits, all of which would have an impact on our effective tax rate, if recognized.

We do not believe it is possible to reasonably estimate the potential effect of changes to the assumptions and estimates identified because the resulting change to our tax liability, if any, is dependent on numerous factors which cannot be reasonably estimated. These include, among others, the amount and nature of additional taxes potentially asserted by local tax authorities; the willingness of local tax authorities to negotiate a fair settlement through an administrative process; the impartiality of the local courts; and the potential for changes in the tax paid to one country to either produce, or fail to produce, an offsetting tax change in other countries. Our experience has been that the estimates and assumptions we have used to provide for future tax assessments have proven to be appropriate. However, past experience is only a guide and the potential exists that the tax resulting from the resolution of current and potential future tax controversies may differ materially from the amounts accrued.

Judgment is required in determining whether deferred tax assets will be realized in full or in part. When it is estimated to be more-likely-than-not that all or some portion of specific deferred tax assets, such as foreign tax credit carryovers or net operating loss carry forwards, will not be realized, a valuation allowance must be established for the amount of the deferred tax assets that are estimated to not be realizable. As of March 31, 2018, we have established deferred tax assets for foreign taxes we expect to be realizable. Our ability to realize the benefit of our deferred tax assets requires that we achieve certain future earnings levels prior to the expiration of our foreign tax credit carryforwards. In the event that our earnings performance projections or future financial conditions do not indicate that we will be able to benefit from our deferred tax assets, valuation allowances would be established following the “more-likely-than-not” criteria. We periodically evaluate our ability to utilize our deferred tax assets and, in accordance with accounting guidance related to accounting for income taxes, will record any resulting adjustments that may be required to deferred income tax expense in the period for which an existing estimate changes. If our facts or financial results were to change, thereby impacting the likelihood of establishing and then realizing the deferred tax assets, judgment would have to be applied to determine changes to the amount of the valuation allowance in any given period. Such changes could result in either a decrease or an increase in our provision for income taxes, depending on whether the change in judgment resulted in an increase or a decrease to the valuation allowance. We continually evaluate strategies that could allow for the future utilization of our deferred tax assets.

We consider the earnings of certain foreign subsidiaries to be indefinitely invested outside the U.S. on the basis of estimates that future cash generation will be sufficient to meet future U.S. cash needs and specific plans for foreign reinvestment of those earnings. As such, as of March 31, 2018, we have not provided for deferred taxes on the unremitted earnings of certain foreign subsidiaries that are indefinitely invested abroad of $517.9 million. Pursuant to the Act, these earnings were subject to the mandatory one-time transition tax and eligible to be repatriated to the U.S. without additional U.S. tax. Although these foreign earnings have been deemed to be repatriated from a U.S. federal income tax perspective, we have not yet completed our assessment of the U.S. tax reform on our plans to reinvest foreign earnings and as such have not changed our prior conclusion that the unremitted earnings are indefinitely reinvested. Accordingly, we have not provided deferred taxes on these unremitted earnings. If our expectations were to change, withholding and other applicable taxes incurred upon repatriation, if any, are not expected to have a significant impact on our results of operations.

We have not provided for deferred taxes in circumstances where we expect that, due to the structure of operations and applicable law, the operations in such jurisdictions will not give rise to future tax consequences. Should our expectations change regarding the expected future tax consequences, we may be required to record additional deferred taxes that could have a material adverse effect on our consolidated financial position, results of operations and cash flows.

On June 23, 2016, the U.K. voted to leave the E.U. The exact nature, process and timing of the U.K.’s exit from the E.U. are unknown. This has to date created business uncertainty: The U.K.’s future approach to E.U. freedom of movement; market volatility; fluctuations in foreign exchange rates; changes to commodity prices; interest rates; and potential changes to existing double tax treaties, all of which may impact us. Although it is too early to quantify the precise impact of the U.K.’s exit from the E.U., we will continue to monitor the economic consequences of the referendum.

Property and Equipment

Our net property and equipment represents 65% of our total assets as of March 31, 2018. We determine the carrying value of these assets based on our property and equipment accounting policies, which incorporate our estimates, assumptions, and judgments relative to capitalized costs, useful lives and salvage values of our assets.

Our property and equipment accounting policies are also designed to depreciate our assets over their estimated useful lives. The assumptions and judgments we use in determining the estimated useful lives and residual values of our property and equipment reflect both historical experience and expectations regarding future operations, utilization and performance of our assets. The use of different estimates, assumptions and judgments in the establishment of property and equipment accounting policies, especially those involving the useful lives and residual values of our aircraft, would likely result in materially different net book values of our assets and results of operations.

Useful lives and residual values of aircraft are difficult to estimate due to a variety of factors, including changes in operating conditions or environment, the introduction of technological advances in aviation equipment, changes in market or economic conditions, including changes in demand for certain types of aircraft, and changes in laws or regulations affecting the aviation or offshore oil and gas industry. We evaluate the remaining useful lives of our aircraft when certain events occur that directly impact our assessment of their remaining useful lives. Our consideration of ultimate residual value takes into account current expectations of fair market value and the expected time to ultimate disposal. The determination of the ultimate value to be received upon sale depends largely upon the condition of the aircraft and the flight time left on the aircraft and major components until the next major maintenance check is required. The future value also depends on the aftermarket that exists as of that date, which can differ substantially over time.

We review our property and equipment for impairment when events or changes in circumstances indicate that the carrying value of assets or asset groups may be impaired or when reclassifications are made between property and equipment and assets held for sale.

Asset impairment evaluations for held for use asset groups are based on estimated undiscounted cash flows for the asset group being evaluated. If the sum of the expected future cash flows is less than the carrying amount of the asset group, we would be required to recognize an impairment loss. When determining fair value, we utilize various assumptions, including projections of future cash flows. A change in these underlying assumptions will cause a change in the results of the tests and, as such, could cause fair value to be less than the carrying amounts. In such event, we would then be required to record a corresponding charge, which would reduce our earnings. We continue to evaluate our estimates and assumptions and believe that our assumptions, which include an estimate of future cash flows based upon the anticipated performance of the underlying contracts, are appropriate. Impairment evaluations for assets held for sale are based on estimates derived from historical experience with sales, recent transactions involving similar assets, quoted market prices for similar assets and condition and location of aircraft to be sold.

Supply and demand are the key drivers of aircraft idle time and our ability to contract our aircraft at economical rates. During periods of oversupply, it is not uncommon for us to have aircraft idled for extended periods of time, which could be an indication that an asset group may be impaired. In most instances our aircraft could be used interchangeably. In addition, our aircraft are generally equipped to operate throughout the world. Because our aircraft are mobile, we may move aircraft from a weak geographic market to a stronger geographic market if an adequate opportunity arises to do so. As such, our aircraft are considered to be interchangeable within classes or asset groups and accordingly, our impairment evaluation is made by asset group. Additionally, our management periodically makes strategic decisions related to our fleet that involve the possible removal of all or a substantial portion of specific aircraft types from our fleet, at which time these aircraft are reclassified to held for sale and subsequently sold or otherwise disposed of.

For aircraft types that are still operating where management has made the decision to sell or abandon the aircraft type at a fixed date, an analysis is completed to determine whether depreciation needs to be accelerated or additional depreciation recorded for an expected reduction in residual value at the planned disposal date.

Where a determination has been made to exit an entire asset group, the asset group is reviewed for potential impairment. An impairment loss is recorded in the period in which it is determined that the aggregate carrying amount of assets within an asset group is not recoverable. This requires us to make judgments regarding long-term forecasts of future revenue and cost related to the assets subject to review. In turn, these forecasts are uncertain in that they require assumptions about demand for our services, future market conditions and technological developments. Significant and unanticipated changes to these assumptions could require a provision for impairment in a future period. Given the nature of these evaluations and their application to specific asset groups and specific times, it is not possible to reasonably quantify the impact of changes in these assumptions.

68

Pension Benefits

Pension obligations are actuarially determined and are affected by assumptions including discount rates, compensation increases and employee turnover rates. The recognition of these obligations through the statement of operations is also affected by assumptions about expected returns on plan assets. We evaluate our assumptions periodically and make adjustments to these assumptions and the recorded liabilities as necessary.

Three of the most critical assumptions are the expected long-term rate of return on plan assets, the assumed discount rate and the mortality rate. We evaluate our assumptions regarding the estimated long-term rate of return on plan assets based on historical experience and future expectations on investment returns, which are calculated by our third-party investment advisor utilizing the asset allocation classes held by the plans’ portfolios. We utilize a British pound sterling denominated AA corporate bond index as a basis for determining the discount rate for our U.K. plans. We base mortality rates utilized on actuarial research on these rates, which are adjusted to allow for expected mortality within our industry segment and, where available, individual plan experience data. Changes in these and other assumptions used in the actuarial computations could impact our projected benefit obligations, pension liabilities, pension expense and other comprehensive income. We base our determination of pension expense on a fair value valuation of assets and an amortization approach for assessed gains and losses that reduces year-to-year volatility. This approach recognizes investment and other actuarial gains or losses over the average remaining lifetime of the plan members. Investment gains or losses for this purpose are the difference between the expected return calculated using the market-related value of assets and the actual return based on the market-related value of assets.

Allowance for Doubtful Accounts

We establish allowances for doubtful accounts on a case-by-case basis when we believe the payment of amounts owed to us is unlikely to occur. In establishing these allowances, we consider a number of factors, including our historical experience, changes in our client’s financial position and restrictions placed on the conversion of local currency to U.S. dollars, as well as disputes with clients regarding the application of contract provisions to our services.

We derive a significant portion of our revenue from services to major integrated oil and gas companies and government-owned or government-controlled oil and gas companies. Our receivables are concentrated in certain oil-producing countries. We generally do not require collateral or other security to support client receivables. If the financial condition of our clients was to deteriorate or their access to freely-convertible currency was restricted, resulting in impairment of their ability to make the required payments, additional allowances may be required.

Inventory Allowance

We maintain inventory that primarily consists of spare parts to service our aircraft. We establish an allowance to distribute the cost of spare parts expected to be on hand at the end of an aircraft type’s life over the service lives of the related equipment, taking into account the estimated salvage value of the parts. Also, we periodically review the condition and continuing usefulness of the parts to determine whether the realizable value of this inventory is lower than its book value. Parts related to aircraft types that our management has determined will no longer be included in our fleet or will be substantially reduced in our fleet in future periods are specifically reviewed. If our valuation of these parts is significantly lower than the book value of the parts, an additional provision may be required.

Contingent Liabilities

We establish reserves for estimated loss contingencies when we believe a loss is probable and the amount of the loss can be reasonably estimated. Our contingent liability reserves relate primarily to potential tax assessments, litigation, personal injury claims and environmental liabilities. Income for each reporting period includes revisions to contingent liability reserves resulting from different facts or information which becomes known or circumstances which change and affect our previous assumptions with respect to the likelihood or amount of loss. Such revisions are based on information which becomes known or circumstances that change after the reporting date for the previous period through the reporting date of the current period. Reserves for contingent liabilities are based upon our assumptions and estimates regarding the probable outcome of the matter. Should the outcome differ from our assumptions and estimates or other events result in a material adjustment to the accrued estimated reserves, revisions to the estimated reserves for contingent liabilities would be required to be recognized.

69

Goodwill Impairment

We perform a test for impairment of our goodwill annually as of March 31 and whenever events or circumstances indicate impairment may have occurred. We first assess qualitative factors to determine if it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount and if a quantitative assessment should be performed. An entity may also bypass the qualitative assessment for any reporting unit in any period and proceed directly to the quantitative impairment test. The qualitative factors considered during our assessment include the capital markets environment, global economic conditions, the demand for helicopter services, changes in our results of operations, the magnitude of the excess of fair value over the carrying amount of each reporting unit as determined in prior years’ quantitative testing and other factors.

We estimate the implied fair value of the reporting units using a variety of valuation methods, including the income and market approaches. The determination of estimated fair value require us to use significant unobservable inputs, representative of a Level 3 fair value measurement, including assumptions related to the future performance of the reporting units, such as projected demand for our services and rates.

The income approach is based on a discounted cash flow model, which utilizes present values of cash flows to estimate fair value. The future cash flows are projected based on our estimates of future rates for our services, utilization, operating costs, capital requirements, growth rates and terminal values. Forecasted rates and utilization take into account current market conditions and our anticipated business outlook. Operating costs are forecasted using a combination of our historical average operating costs and expected future costs, including ongoing cost reduction initiatives. Capital requirements in the discounted cash flow model are based on management’s estimates of future capital costs resulting from expected market demand in future periods. The estimated capital requirements include cash outflows for new aircraft, infrastructure and improvements. A terminal period is used to reflect our estimate of stable, perpetual growth. The future cash flows are discounted using a market-participant risk-adjusted weighted average cost of capital (“WACC”) for each of the reporting units and in total. These assumptions are derived from unobservable inputs and reflect management’s judgments and assumptions.

The market approach is based upon the application of price-to-earnings multiples to management’s estimates of future earnings adjusted for a control premium. Management’s earnings estimates are derived from unobservable inputs that require significant estimates, judgments and assumptions as described in the income approach.

For purposes of the goodwill impairment test, we calculate the reporting units’ estimated fair values as the average of the values calculated under the income approach and the market approach. As of March 31, 2018, we had goodwill related to Airnorth. We performed a qualitative analysis and concluded it is more likely than not that the fair value of Airnorth is not less than the carrying value and, therefore, did not perform a quantitative analysis for Airnorth. Changes in assumptions used in the fair value calculation could result in an estimated reporting unit fair value that is below the carrying value, which may give rise to an impairment of goodwill.

We evaluate the estimated fair value of our reporting units compared to our market capitalization. The estimates used to determine the fair value of the reporting units discussed above reflect management’s best estimates. Changes in the assumption used in the fair value calculation could result in an estimated reporting unit fair value that is below the carrying value, which may give rise to an impairment of goodwill.

Recent Accounting Pronouncements

Item 7A.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 below. The sensitivity analyses presented do not consider the effects that such adverse changes may have on overall economic activity, nor do they consider additional actions we may take to mitigate our exposure to such changes. Actual results may differ. See the notes to our consolidated financial statements included in Item 8 of this Annual Report for a description of our accounting policies and other information related to these financial instruments.

Foreign Currency Risk

Through our foreign operations, we are exposed to currency fluctuations and exchange rate risks. The majority of our revenue and expense from our North Sea operations are in British pound sterling. Approximately 35% of our gross revenue for fiscal year 2018 was translated for financial reporting purposes from British pound sterling into U.S. dollars. In addition, some of our contracts to provide services internationally provide for payment in foreign currencies. Our foreign exchange rate risk is even greater when our revenue is denominated in a currency different from the associated costs. We attempt to minimize our foreign exchange rate exposure by contracting the majority of our services other than our North Sea operations in U.S. dollars. During fiscal year 2018, we entered into foreign currency put option contracts of £5 million per month through November 2018 to protect against a portion of our foreign exchange risks related to our operating income. See Note 6 in the “Notes to Consolidated Financial Statements” included elsewhere in this Annual Report for discussion of these hedging transactions. During fiscal years 2017 and 2016, we did not enter into hedging transactions to protect against foreign exchange risks related to our operating income.

Throughout fiscal years 2018, 2017 and 2016, our primary foreign currency exposure has been to the British pound sterling, the euro, the Australian dollar, the Norwegian kroner, and the Nigerian naira. The value of these currencies has fluctuated relative to the U.S. dollar as indicated in the following table:

	Fiscal Years Ended March 31,
	2018	2017	2016
One British pound sterling into U.S. dollars

Our earnings from unconsolidated affiliates, net of losses, are also affected by the impact of changes in foreign currency exchange rates on the reported results of our unconsolidated affiliates. Earnings from unconsolidated affiliates, net of losses, decreased by $2.0 million, $3.2 million and $22.4 million during fiscal years 2018, 2017 and 2016, respectively, as a result of the impact of changes in foreign currency exchange rates on the earnings of our unconsolidated affiliates, primarily the impact of changes in the Brazilian real to U.S. dollar exchange rate on earnings for our affiliate in Brazil. The value of the Brazilian real has fluctuated relative to the U.S. dollar as indicated in the following table:

	Fiscal Years Ended March 31,
	2018	2017	2016
One Brazilian real into U.S. dollars
High	0.3244	0.3267	0.3437
Average	0.3108	0.3036	0.2816
Low	0.2995	0.2702	0.2378
At period-end	0.3009	0.3150	0.2822

We estimate that the fluctuation of these currencies for fiscal year 2018 versus fiscal year 2017 had the following effect on our financial condition and results of operations (in thousands):

Revenue	$	14,150
Operating expense	(16,178		)
Earnings from unconsolidated affiliates, net of losses	1,237
Non-operating expense	368
Income before provision for income taxes	(423		)
Provision from income taxes	3,416
Net income	2,993
Cumulative translation adjustment	30,196
Total stockholders’ investment	$	33,189

A hypothetical 10% change in the average U.S. dollar exchange rate relative to other currencies would have affected our revenue, operating expense and operating income for fiscal year 2018 as follows:

	British pound sterling		Euro		Australian dollar		Norwegian kroner		Nigerian Naira
Revenue	3.5	%	0.1	%	1.1	%	(1.0	)%	0.1	%
Operating expense	2.6	%	0.1	%	1.2	%	1.0	%	0.2	%
Operating income	(26.7	)%	2.5	%	3.4	%	3.0	%	4.0	%

The effect of the hypothetical change in exchange rates ignores the effect this movement may have on other variables, including competitive risk. If it were possible to quantify the impact of competitive risk, the results could be different from the sensitivity effects shown above. In addition, all currencies may not uniformly strengthen or weaken relative to the U.S. dollar. In reality, some currencies may weaken while others may strengthen.

In the past three fiscal years, our stockholders’ investment has decreased by $16.9 million as a result of translation adjustments. Changes in exchange rates could cause significant changes in our financial position and results of operations in the future.

As a result of the changes in exchange rates, we recorded foreign currency transaction losses of $2.6 million, $2.9 million and $4.3 million during fiscal years 2018, 2017 and 2016, respectively.

A hypothetical 10% decrease in the value of the foreign currencies in which our business is denominated relative to the U.S. dollar as of March 31, 2018 would result in a $35.8 million decrease in the fair value of our net monetary liabilities denominated in currencies other than U.S. dollars.

72

Credit Risk

The market for our services and products is primarily the offshore oil and gas industry, and our clients consist primarily of major integrated, national and independent oil and gas producers. Additionally, we provide public sector SAR services in the U.K. to the DfT. We perform ongoing credit evaluations of our clients and have not historically required collateral. We maintain allowances for potential credit losses.

Cash equivalents, which consist of funds invested in highly-liquid debt instruments with original maturities of 90 days or less, are held by major banks or investment firms, and we believe that credit risk in these instruments is minimal. We also manage our credit risk by not entering into complex financial transactions or those with a perceived high level of credit risk.

For more information on the impact of the global market conditions see Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Executive Overview — Market Outlook” and Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Financial Condition and Sources of Liquidity” included elsewhere in this Annual Report.

Interest Rate Risk

As of March 31, 2018, we had $1.5 billion of debt outstanding, of which $654.5 million carried a variable rate of interest. The market value of our fixed rate debt fluctuates with changes in interest rates. The fair value of our debt has been estimated in accordance with the accounting standard regarding fair value. The fair value of our fixed rate long-term debt is estimated based on quoted market prices and has not been updated for any possible acceleration provisions in our debt instruments. The carrying and fair value of our long-term debt, including the current portion and excluding unamortized debt issuance costs, are as follows (in thousands):

	March 31,
	2018				2017
	Carrying Value		Fair Value		Carrying Value		Fair Value

If prevailing market interest rates had been 1% higher as of March 31, 2018, and all other factors affecting our debt remained the same, the fair value of the 6¼% Senior Notes, 4½% Convertible Senior Notes and 8.75% Senior Secured Notes would have decreased by $32.6 million, or 3.9%. Under comparable sensitivity analysis as of March 31, 2017, the fair value of the 6 ¼% Senior Notes would have decreased by $13.9 million, or 4.3%.

Item 8. Consolidated Financial Statements and Supplementary Data

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors

Bristow Group Inc.:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Bristow Group Inc. and subsidiaries (the Company) as of March 31, 2018 and 2017, the related consolidated statements of operations, comprehensive loss, cash flows and stockholders’ investment and redeemable noncontrolling interest for each of the years in the three-year period ended March 31, 2018, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of March 31, 2018 and 2017, and the results of its operations and its cash flows for each of the years in the three-year period ended March 31, 2018, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of March 31, 2018, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated May 23, 2018, except for 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, expressed an adverse opinion on the effectiveness of the Company’s internal control over financial reporting.

Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has suffered recurring losses from operations and its liquidity outlook, along with the risks and uncertainties related to its Chapter 11 voluntary petition, raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. 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 audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

BRISTOW GROUP AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 — OPERATIONS, BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Operations

Bristow Group Inc., a Delaware corporation (together with its consolidated entities, unless the context requires otherwise, “Bristow Group”, the “Company”, “we”, “us”, or “our”), is the leading provider of industrial aviation services to the worldwide offshore energy industry based on the number of aircraft operated. With a fleet of 405 aircraft as of March 31, 2018, including 110 held by unconsolidated affiliates, we and our affiliates conduct 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 and our affiliates also provide private sector search and rescue (“SAR”) services in Australia, Canada, Norway, Russia, Trinidad and the United States, and public sector SAR services in the U.K. on behalf of the Maritime & Coastguard Agency. Certain of our affiliates also provide regional fixed wing scheduled and charter services in the U.K., Nigeria and Australia.

Bankruptcy, Restructuring Support Agreement and Going Concern

The Company’s liquidity outlook has changed since the date of the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2018, originally filed with the U.S. Securities and Exchange Commission (“SEC”) on May 23, 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 (the Original Filing, as amended by this Amendment No. 1, this Amended 10-K”), 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 this Amended 10-K 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 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 this Amended 10-K on our consolidated balance sheet.

As discussed in the Explanatory Note in this Annual Report, 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”) 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.

As previously disclosed in the Company’s Current Report on Form 8-K filed with the SEC on May 13, 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

80

BRISTOW GROUP INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

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 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 consolidated financial statements do not include any adjustments that might result from the outcome of 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 consolidated statements of changes in stockholders’ investment and redeemable noncontrolling interest reflect immaterial adjustments to the historical balances in retained earnings and accrued wages, benefits and related taxes for the years ended March 31, 2016, 2017 and 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 for March 31, 2015, 2016, 2017 and 2018 of $4.9 million. Retained earnings as reported was $1,284,442,000 and $1,172,273,000 for March 31, 2015 and 2016, respectively, compared to as adjusted of $1,279,493,000 and $1,167,324,000 for March 31, 2015 and 2016, respectively, after the correction. In addition, below are amounts as reported and as adjusted for each year presented (in thousands):

	March 31, 2018				March 31, 2017
	As reported	Adjustments		As adjusted	As reported	Adjustments		As adjusted
Accrued wages, benefits and related taxes	62,385	4,949		67,334	59,077	4,949		64,026
Retained earnings	793,783	(4,949	)	788,834	991,906	(4,949	)	986,957
Total Bristow Group stockholders’ investment	1,175,840	(4,949	)	1,170,891	1,289,207	(4,949	)	1,284,258
Total stockholders’ investment	1,183,093	(4,949	)	1,178,144	1,294,232	(4,949	)	1,289,283

The income statement and cash flow impact of this accrual for the fiscal years ended March 31, 2016, 2017 and 2018 were not corrected as they were considered to be inconsequential to the Company’s prior period interim and annual consolidated financial statements.

We apply the equity method of accounting for investments in entities if we have the ability to exercise significant influence over an entity that (a) does not meet the variable interest entity criteria or (b) meets the variable interest entity criteria, but for which we are not deemed to be the primary beneficiary. We apply the cost method of accounting for investments in other entities if we do not have the ability to exercise significant influence over the unconsolidated affiliate. These investments in private companies are carried at cost and are adjusted only for capital distributions and other-than-temporary declines in value. Dividends from cost method investments are recognized in earnings from unconsolidated affiliates, net of losses, when paid.

Our fiscal year ends March 31, and we refer to fiscal years based on the end of such period. Therefore, the fiscal year ended March 31, 2018 is referred to as fiscal year 2018.

Certain reclassifications of prior period information have been made to conform to the presentation of the current period information as a result of an adoption of a required accounting standard. In prior period financial statements, we had included employee taxes paid for withheld shares as a cash flow operating activity. During fiscal year 2018, we have reclassified employee taxes paid for withheld shares to be presented as a cash flow financing activity as a result of the adoption of new accounting standards effective April 1, 2017. These reclassifications had no effect on our consolidated statements of operations or our consolidated balance sheet as previously reported.

Summary of Significant Accounting Policies

Use of Estimates — The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expense during the reporting period. Actual results could differ from those estimates. Areas where accounting estimates are made by management include:

• Allowances for doubtful accounts;

• Inventory allowances;

• Property and equipment;

• Goodwill, intangible and other long-lived assets;

• Pension benefits;

• Contingent liabilities; and

• Taxes.

Cash and Cash Equivalents — Our cash equivalents include funds invested in highly-liquid debt instruments with original maturities of 90 days or less.

Accounts Receivable — Trade and other receivables are stated at net realizable value. We grant short-term credit to our clients, primarily major integrated, national and independent oil and gas companies. We establish allowances for doubtful accounts on a case-by-case basis when a determination is made that the required payment is unlikely to occur. In establishing these allowances, we consider a number of factors, including our historical experience, change in our clients’ financial position and restrictions placed on the conversion of local currency into U.S. dollars, as well as disputes with clients regarding the application of contract provisions to our services. Also included in accounts receivable as of March 31, 2018 is $19.8 million for cash collateralization of letters of credit.

Balance – end of fiscal year	$	3,304		$	4,498		$	5,562

During fiscal year 2016, the allowance for doubtful accounts for non-affiliates was increased primarily for amounts due from two clients in Nigeria and one client in Australia for which we no longer believed collection was probable.

As of March 31, 2018 and 2017, there were no allowances for doubtful accounts related to accounts receivable due from affiliates.

Inventories — Inventories are stated at the lower of average cost or net realizable value and consist primarily of spare parts. The following table is a rollforward of the allowance related to dormant, obsolete and excess inventory (in thousands):

	Fiscal Year Ended March 31,
	2018			2017			2016
Balance – beginning of fiscal year	$	21,514		$	27,763		$	45,414
Impairment of inventories	—			7,572			5,439
Additional allowances	6,355			1,617			192

Foreign currency effects	1,514			(803		)	(854		)
Balance – end of fiscal year	$	26,030		$	21,514		$	27,763

During fiscal years 2018, 2017 and 2016, we increased our inventory allowance by $6.4 million, $1.6 million and $0.2 million, respectively, as a result of our periodic assessment of inventory that was dormant or obsolete within our operational fleet of aircraft. For discussion of impairment of inventories, see Loss on Impairment below. The impairment of inventories is included in loss on impairment and additional allowances are included in direct costs on our consolidated statements of operations.

Prepaid Expenses and Other Current Assets — As of March 31, 2018 and 2017, prepaid expenses and other current assets included the short-term portion of contract acquisition and pre-operating costs totaling $10.8 million and $9.7 million, respectively, related to SAR contracts in the U.K. and two client contracts in Norway. These contract acquisition and pre-operating costs are recoverable under the contracts and are being expensed over the terms of the contracts. During fiscal years 2018 and 2017, we expensed $11.4 million and $16.9 million, respectively, due to the start-up of these contracts and the cancellation of a contract in Australia.

Property and Equipment — Property and equipment are stated at cost. Property and equipment includes construction in progress, primarily consisting of progress payments on aircraft purchases and facility construction, of $67.7 million and $199.3 million as of March 31, 2018 and 2017, respectively. Interest costs applicable to the construction of qualifying assets are capitalized as a component of the cost of such assets.

Depreciation and amortization are provided using the straight-line method over the estimated useful lives of the assets. The estimated useful lives of aircraft generally range from 5 to 15 years, and the residual value used in calculating depreciation of aircraft generally ranges from 30% to 50% of cost. The estimated useful lives for buildings on owned properties range from 15 to 30 years. Other depreciable assets are depreciated over estimated useful lives ranging from 3 to 15 years, except for leasehold improvements which are depreciated over the lesser of the useful life of the improvement or the lease term (including any period where we have options to renew if it is probable that we will renew the lease). The cost and related accumulated depreciation of assets sold or otherwise disposed of are removed from the accounts and the resulting gains or losses are included in gain (loss) on disposal of assets.

We capitalize betterments and improvements to our aircraft and depreciate such costs over the remaining useful lives of the aircraft. Betterments and improvements increase the life or utility of an aircraft.

For further details on property and equipment, see Note 3.

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.

The Bristow Norway and Eastern Airways International Limited (“Eastern Airways”) acquisitions, completed in October 2008 and February 2014, respectively, included in our Europe Caspian region, resulted in intangible assets for client contracts, client relationships, trade names and trademarks, internally developed software and licenses. The Capiteq Limited, operating under the name Airnorth, acquisition completed in January 2015, included in our Asia Pacific region, resulted in intangible assets for client contracts, client relationships and trade name and trademarks. For discussion of impairment of long-lived assets, including purchased intangibles subject to amortization, see Loss on Impairment below.

Other Assets — In addition to the intangible assets discussed above, other assets primarily include deferred tax assets of $42.6 million and $34.8 million as of March 31, 2018 and 2017, respectively, and the long-term portion of contract acquisition and pre-operating costs totaling $50.6 million and $51.1 million as of March 31, 2018 and 2017, respectively, related to SAR contracts in the U.K. and two client contracts in Norway, which are recoverable under the contracts and are being expensed over the life of the contracts.

Contingent Liabilities — We establish reserves for estimated loss contingencies when we believe a loss is probable and the amount of the loss can be reasonably estimated. Our contingent liability reserves relate primarily to potential tax assessments, litigation, personal injury claims and environmental liabilities. Results for each reporting period include revisions to contingent liability reserves resulting from different facts or information which becomes known or circumstances which change and affect our previous assumptions with respect to the likelihood or amount of loss. Such revisions are based on information which becomes known or circumstances that change after the reporting date for the previous period through the reporting date of the current period. Reserves for contingent liabilities are based upon our assumptions and estimates regarding the probable outcome of the matter. Should the outcome differ from our assumptions and estimates or other events result in a material adjustment to the accrued estimated reserves, revisions to the estimated reserves for contingent liabilities would be required to be recognized. Legal costs are expensed as incurred.

Proceeds from casualty insurance settlements in excess of the carrying value of damaged assets are recognized in gain (loss) on disposal of assets when we have received proof of loss documentation or are otherwise assured of collection of these amounts.

Some of our acquisitions include a provision that provides for additional consideration to be paid to the sellers of the acquired company based on the achievement of specified performance thresholds.  In such cases, we record the obligations to pay those amounts at fair value at the acquisition date and include such obligations in the consideration transferred. We assess the estimated fair value of the contractual obligation to pay the contingent consideration on a quarterly basis and any changes in estimated fair value are recorded as accretion expense included in depreciation and amortization on our consolidated statements of operations. In other cases, additional consideration is based on the achievement of performance thresholds and continued employment with the Company. In these cases, we record such amounts in general and administrative expense when such additional consideration is earned.

Loss on Impairment

Loss on impairment includes the following (in thousands):

	Fiscal Year Ended March 31,
	2018		2017		2016
Impairment of inventories	$	5,717	$	7,572	$	5,439

Impairment of other long-lived assets	—		—		8,086
	$	91,400	$	16,278	$	55,104

For details on our analysis of impairment of inventories, investment in unconsolidated affiliates, goodwill and other long-lived assets, see discussion below.

Inventories— During fiscal years 2018, 2017 and 2016, we recorded impairment charges of $5.7 million, $7.6 million and $5.4 million, respectively, to write-down certain spare parts within inventories to market value. The impairment charges in fiscal year 2018 were recorded to impair inventory used in our training fleet at Bristow Academy, Inc. (“Bristow Academy”) ($1.2 million) and our fixed wing operations at Eastern Airways ($4.5 million) as a result of changes in expected future utilization of aircraft within those operations. These charges were recorded as a direct reduction in the value of spare parts inventories to record them at net realizable value. The impairment charges in fiscal year 2017 were recorded primarily due to a change in estimate of consumption of inventory and the continued decline in the secondary market for inventory resulting from our decision to cease operation of certain older model aircraft within our fleet in fiscal year 2017. The impairment charges in fiscal year 2016 related primarily to spare parts held for a large aircraft model where we decided to accelerate removal from our fleet by the end of fiscal year 2016. As we had intended to operate these model types longer in certain markets, we identified excess inventory that would not be used on our aircraft and therefore needed to be sold or otherwise disposed of. The charges recorded in fiscal years 2017 and 2016 were recorded as additional allowances required against spare parts supporting the specific aircraft model types.

Investment in Unconsolidated Affiliates — We perform regular reviews of each investee’s financial condition, the business outlook for its products and services, and its present and projected results and cash flows. When an investee has experienced consistent declines in financial performance or difficulties raising capital to continue operations, and when we expect the decline to be other-than-temporary, the investment is written down to fair value. Actual results may vary from estimates due to the uncertainty regarding the projected financial performance of investees, the severity and expected duration of declines in value, and the available liquidity in the capital markets to support the continuing operations of the investees in which we have investments. In fiscal year 2018, we recorded an $85.7 million impairment to our investment in Líder Táxi Aéreo S.A. (“Líder”) in our Americas region. For further details, see below. We did not recognize any impairment charges related to our investments in unconsolidated affiliates in fiscal years 2017 and 2016.

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. Líder’s management has significantly decreased their future financial projections as a result of recent tender awards announced by their largest client, Petrobras. This significant decline in future forecasted results, coupled with previous declining financial results, triggered our review of the investment for potential other-than-temporary impairment as of March 31, 2018.

86

BRISTOW GROUP INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

We estimated the fair value of our investment in Líder using a variety of valuation methods, including the income and market approaches. The determination of estimated fair value required us to use significant unobservable inputs, representative of a Level 3 fair value measurement, including assumptions related to the future performance of the investment, such as projected demand for services and rates.

The income approach was based on a discounted cash flow model, which utilized present values of cash flows to estimate fair value. The future cash flows were projected based on estimates of future rates for services, utilization, operating costs, capital requirements, growth rates and terminal values. Forecasted rates and utilization take into account current market conditions and our anticipated business outlook, both of which have been impacted by the adverse changes in the offshore energy business environment from the current downturn. Operating costs were forecasted using a combination of historical average operating costs and expected future costs, including ongoing cost reduction initiatives. Capital requirements in the discounted cash flow model were based on management’s estimates of future capital costs resulting from expected market demand in future periods. The estimated capital requirements included cash outflows for new aircraft, infrastructure and improvements. A terminal period was used to reflect our estimate of stable, perpetual growth. The future cash flows were discounted using a market-participant risk-adjusted weighted average cost of capital (“WACC”). These assumptions were derived from unobservable inputs and reflect management’s judgments and assumptions.

The market approach was based upon the application of price-to-earnings multiples to management’s estimates of future earnings. Management’s earnings estimates were derived from unobservable inputs that require significant estimates, judgments and assumptions as described in the income approach.

For purposes of the Líder impairment test, we calculated the estimated fair value as the weighted average of the values calculated under the income approach and the market approach.

Goodwill— As discussed above, we test goodwill for impairment on an annual basis or when events or changes in circumstances indicate that a potential impairment exists. For the purposes of performing an analysis of goodwill, we evaluate whether there are reporting units below the reporting segment we disclose for segment reporting purposes by assessing whether our regional management typically reviews results and whether discrete financial information exists at a lower level.

During the three months ended September 30, 2015, we noted rapid and significant declines in the market value of our common stock and an overall reduction in expected operating results resulting from the downturn in the oil and gas industry due to reduced crude oil prices. The impact on our results was reflected in an increase in the number of idle aircraft and reduction in forecasted results across our global oil and gas helicopter operations, and was reflected in reduced operating revenue for our business for the three months ended September 30, 2015, when excluding growth from the U.K. SAR contract and the addition of Airnorth. Based on these factors, we concluded that the fair value of our goodwill could have fallen below its carrying value and that an interim period analysis of goodwill was required.

We performed our analysis of goodwill for the following reporting units as of September 30, 2015, with goodwill as reflected below prior to any impairment recorded:    

•Bristow Norway, within our Europe Caspian region, which included $12.1 million of goodwill;

•Eastern Airways, within our Europe Caspian region, which included $24.6 million of goodwill;

•Airnorth, within our Asia Pacific region, which included $21.9 million of goodwill;

•Our Africa region, which included $5.9 million of goodwill; and

•Bristow Academy, within Corporate and other, which included $10.2 million of goodwill.

We performed the interim impairment test of goodwill across the reporting units discussed above, noting that the estimated fair values of Eastern Airways, Airnorth and our Africa region exceeded the carrying values. The estimated fair values of Bristow Norway and Bristow Academy were below their carrying values, resulting in an impairment of all of the goodwill for those reporting units of $22.3 million reflected in loss on impairment in our statement of operations during fiscal year 2016. We updated the impairment analysis as of March 31, 2016 for the Eastern Airways, Airnorth and our Africa region. The estimated fair value of Airnorth exceeded the carrying value. The estimated fair value of Eastern Airways and our Africa region was below the carrying value, resulting in an impairment of a portion of the goodwill for Eastern Airways of $13.1 million and all of the goodwill for Africa of $6.2 million reflected in our loss on impairment in our statement of operations during fiscal year 2016.

BRISTOW GROUP INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

During the three months ended December 31, 2016, we noted an overall reduction in expected operating results for Eastern Airways from the continued downturn in the oil and gas market and performed an interim impairment test of goodwill for Eastern Airways. Based on this factor, we concluded that the fair value of our goodwill could have fallen below its carrying value and that an interim period analysis of goodwill was required.

We performed the interim impairment test of goodwill for Eastern Airways as of December 31, 2016, noting that the estimated fair value of Eastern Airways was below its carrying value, resulting in an impairment of all of the remaining goodwill related to Eastern Airways and a loss of $8.7 million reflected in loss on impairment in our statement of operations for fiscal year 2017.

The only remaining goodwill recorded as of March 31, 2018 relates to Airnorth within our Asia Pacific region. We did not have any triggering events to test Airnorth for impairment during fiscal years 2018 or 2017.

We estimated the implied fair value of the reporting units using a variety of valuation methods, including the income and market approaches. The determination of estimated fair value required us to use significant unobservable inputs, representative of a Level 3 fair value measurement, including assumptions related to the future performance of the reporting units, such as projected demand for our services and rates.

The income approach was based on a discounted cash flow model, which utilized present values of cash flows to estimate fair value. The future cash flows were projected based on our estimates of future rates for our services, utilization, operating costs, capital requirements, growth rates and terminal values. Forecasted rates and utilization take into account current market conditions and our anticipated business outlook, both of which have been impacted by the adverse changes in the offshore energy business environment from the current downturn. Operating costs were forecasted using a combination of our historical average operating costs and expected future costs, including ongoing cost reduction initiatives. Capital requirements in the discounted cash flow model were based on management’s estimates of future capital costs resulting from expected market demand in future periods. The estimated capital requirements included cash outflows for new aircraft, infrastructure and improvements. A terminal period was used to reflect our estimate of stable, perpetual growth. The future cash flows were discounted using a market-participant risk-adjusted WACC for each of the reporting units individually and in the aggregate. These assumptions were derived from unobservable inputs and reflect management’s judgments and assumptions.

The market approach was based upon the application of price-to-earnings multiples to management’s estimates of future earnings adjusted for a control premium. Management’s earnings estimates were derived from unobservable inputs that require significant estimates, judgments and assumptions as described in the income approach.

For purposes of the goodwill impairment test, we calculated the reporting units’ estimated fair value as the average of the values calculated under the income approach and the market approach.

During fiscal year 2016, we evaluated the estimated fair value of our reporting units compared to our market capitalization. The aggregate fair values of our reporting units exceeded our market capitalization, and we believe the resulting implied control premium was reasonable based on recent market transactions within our industry or other relevant benchmark data. During fiscal years 2018 and 2017, this calculation was not performed because the reporting unit with goodwill did not represent a significant portion of our business.

The estimates used to determine the fair value of the reporting units discussed above reflect management’s best estimates, and we believe they are reasonable. Future declines in the reporting units’ operating performance or our anticipated business outlook may reduce the estimated fair value of these reporting units and result in additional impairments. Factors that could have a negative impact on the fair value include, but are not limited to:

• decreases in estimated rates and utilization due to greater-than-expected market pressures, downtime and other risks associated with offshore energy operations;

•sustained declines in our common stock price;

•decreases in revenue due to our inability to attract and retain skilled personnel;

• changes in worldwide offshore energy transportation supply and demand, competition or technology;

• changes in future levels of drilling activity and expenditures, whether as a result of global capital markets and liquidity, prices of oil and natural gas or otherwise, which may cause our clients to further reduce offshore production and drilling activities;

88

BRISTOW GROUP INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

• possible cancellation or suspension of contracts as a result of mechanical difficulties, performance or other reasons;

• inability to manage costs during the current downturn and in future periods;

• increases in the market-participant risk-adjusted WACC; and

•declines in anticipated growth rates.

Adverse changes in one or more of these factors could result in additional goodwill impairment in future periods.

Other Long-lived Assets — Long-lived assets, such as property and equipment, and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If the carrying amount of an asset group to be held and used exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset group exceeds the fair value of the asset group. See discussion of impairment of assets held for sale and property and equipment in Note 3. During fiscal year 2016, we recorded an impairment of our Eastern Airways purchased intangibles in our Europe Caspian region of $8.1 million related to our client relationships. In fiscal year 2016, we noted an overall reduction in expected operating results for Eastern Airways from the continued downturn in the oil and gas market and performed impairment tests of intangibles for Eastern Airways. The fair value of Eastern Airways intangibles was estimated using the income approach. The income approach indicates value for a subject asset based on the present value of cash flows projected to be generated by the asset. Projected cash flows are discounted at a required market rate of return that reflects the relative risk of achieving the cash flows and the time value of money.

Other Accrued Liabilities — Other accrued liabilities of $66.0 million and $46.7 million as of March 31, 2018 and 2017, respectively, includes the following (in thousands):

⁽¹⁾  See Note 3 for further details on deferred original equipment manufacturer (“OEM”) cost recovery.

Deferred Sale Leaseback Advance — During fiscal year 2014, we received payment of approximately $106.1 million for progress payments we had made on seven aircraft under construction, and we assigned any future payments due on these construction agreements to the purchaser. As we had the obligation and intent to lease the aircraft back from the purchaser upon completion, we recorded a liability equal to the cash received and additional payments made by the purchaser totaling $147.4 million, with a corresponding increase to construction in progress. During fiscal year 2015, we took delivery and entered into leases for five of the aircraft and removed a total of $183.7 million and $182.6 million from construction in progress and deferred sale leaseback advance, respectively, on our consolidated balance sheet. During fiscal year 2016, we took delivery and entered into leases for the remaining two aircraft and removed a total of $75.8 million and $74.3 million from construction in progress and deferred sale leaseback advance, respectively, on our consolidated balance sheet. As of March 31, 2016, the construction in progress and deferred sale leaseback advance liability related to these deferred sale leaseback transactions were removed from our consolidated balance sheet.

Revenue Recognition — In general, we recognize revenue when it is both realized or realizable and earned. We consider revenue to be realized or realizable and earned when the following conditions exist: there is persuasive evidence of an arrangement (generally a client contract exists); the services or products have been performed or delivered to the client; the sales price is fixed or determinable; and collection has occurred or is probable.

BRISTOW GROUP INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Revenue from helicopter services, including SAR services, is recognized based on contractual rates as the related services are performed. The charges under these contracts are generally based on a two-tier rate structure consisting of a daily or monthly fixed fee plus additional fees for each hour flown. These contracts are for varying periods and generally permit the client to cancel the contract before the end of the term. We also provide services to clients on an “ad hoc” basis, which usually entails a shorter contract notice period and duration. The charges for ad hoc services are based on an hourly rate or a daily or monthly fixed fee plus additional fees for each hour flown. 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 rate increases when the criteria outlined above have been met. This generally includes written recognition from the clients that they are in agreement with the amount of the rate escalation. Cost reimbursements from clients are recorded as reimbursable revenue with the related reimbursed costs recorded as reimbursable expense on our consolidated statements of operations.

Eastern Airways and Airnorth primarily earn revenue through charter and scheduled airline services and provision of airport services (Eastern Airways only). Both chartered and scheduled airline service revenue is recognized net of passenger taxes and discounts. Revenue is recognized 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. Airport services revenue is recognized when earned.

Prior to the sale on November 1, 2017, Bristow Academy, our helicopter training unit, primarily earned revenue from military training, flight training provided to individual students and ground school courses. We recognized revenue from these sources using the same revenue recognition principles described above as services were provided. We consider revenue to be realized or realizable and earned when the following conditions exist: there is persuasive evidence of an arrangement (generally a contract exists); the services have been performed or delivered to the client or student; the sales price is fixed and determinable; and collection has occurred or is probable.

Pension Benefits — See Note 9 for a discussion of our accounting for pension benefits.

Maintenance and Repairs — We generally charge maintenance and repair costs, including major aircraft component overhaul costs, to earnings as the costs are incurred. However, certain major aircraft components, such as engines and transmissions, are maintained by third-party vendors under contractual agreements also referred to as power-by-the hour maintenance agreements. Under these agreements, we are charged an agreed amount per hour of flying time related to maintenance, repair and overhaul of the parts and components covered. The costs charged under these contractual agreements are recognized in the period in which the flight hours occur. To the extent that we have not yet been billed for costs incurred under these arrangements, these costs are included in accrued maintenance and repairs on our consolidated balance sheets. From time to time, we receive credits from our original equipment manufacturers as settlement for additional labor and maintenance expense costs incurred for aircraft performance issues. We record these credits as a reduction in maintenance expense when the credits are utilized in lieu of cash payments for purchases or services. The cost of certain major overhauls on owned fixed-wing aircraft operated by Eastern Airways and Airnorth are capitalized when incurred and depreciated over the period until the next expected major overhaul. The cost of major overhauls on leased fixed-wing aircraft operated by Eastern Airways and Airnorth are charged to maintenance and repair costs when incurred.

Taxes — We follow the liability method of accounting for income taxes. Under this method, deferred income tax assets and liabilities are determined based upon temporary differences between the carrying amount and tax basis of our assets and liabilities and measured using enacted tax rates and laws that will be in effect when the differences are expected to reverse. The effect on deferred income tax assets and liabilities of a change in the tax rates is recognized in income in the period in which the change occurs. We record a valuation reserve when we believe that it is more likely than not that any deferred income tax asset created will not be realized.

In assessing the realizability of deferred income tax assets, management considers whether it is more-likely-than-not that some portion or all of the deferred income tax assets will not be realized. The ultimate realization of deferred income tax assets is dependent upon the generation of future taxable income during the periods in which such temporary differences become deductible.

We recognize tax benefits attributable to uncertain tax positions when it is more-likely-than-not that a tax position will be sustained upon examination by the authorities. The benefit from a position that has surpassed the more-likely-than-not threshold is the largest amount of benefit that is more than 50% likely to be realized upon settlement. We recognize interest and penalties accrued related to unrecognized tax benefits as a component of benefit (provision) for income taxes in our statement of operations.

Foreign Currency — In preparing our financial statements, we must convert all non-U.S. dollar currencies to U.S. dollars. Balance sheet information is presented based on the exchange rate as of the balance sheet date, and statement of operations information is presented based on the average exchange rate for the period. The various components of stockholders’ investment are presented at their historical average exchange rates. The resulting difference after applying the different exchange rates is the currency translation adjustment, which is reported in stockholders’ investment as accumulated other comprehensive gains or losses. Foreign currency transaction gains and losses are recorded in other income (expense), net in our statement of operations and result from the effect of changes in exchange rates on transactions denominated in currencies other than a company’s functional currency, including transactions between consolidated companies. An exception is made where an intercompany loan or advance is deemed to be of a long-term investment nature, in which instance foreign currency transaction gains or losses are included as currency translation adjustments and are reported in stockholders’ investment as accumulated other comprehensive gains or losses. Changes in exchange rates could cause significant changes in our financial position and results of operations in the future.

As a result of changes in exchange rates, we recorded foreign currency transaction losses of approximately $2.6 million, $2.9 million and $4.3 million during fiscal years 2018, 2017 and 2016, respectively. Our earnings from unconsolidated affiliates, net of losses, are also affected by the impact of changes in foreign currency exchange rates on the reported results of our unconsolidated affiliates. During fiscal years 2018, 2017 and 2016, earnings from unconsolidated affiliates, net of losses, decreased by $2.0 million, $3.2 million and $22.4 million, respectively, as a result of the impact of changes in foreign currency exchange rates on the earnings of our unconsolidated affiliates, primarily the impact of changes in the Brazilian real to U.S. dollar exchange rate on earnings for our affiliate in Brazil. See further discussion of foreign exchange risks and controls under Item 7A. “Quantitative and Qualitative Disclosures about Market Risk” included elsewhere in this Annual Report.

Derivative Financial Instruments — See Note 6 for a discussion of our accounting for derivative financial instruments.

Incentive Compensation — See Note 9 for a discussion of our accounting for incentive compensation arrangements.

Interest Income (Expense), Net — During fiscal years 2018, 2017 and 2016, interest expense, net consisted of the following (in thousands):

	Fiscal Year Ended March 31,
	2018			2017			2016
Interest income	$	677		$	943		$	1,058
Interest expense	(77,737		)	(50,862		)	(35,186		)
Interest expense, net	$	(77,060	)	$	(49,919	)	$	(34,128	)

Other Income (Expense), Net — The amounts for fiscal years 2018, 2017 and 2016 primarily include the foreign currency transaction gains and losses described under “Foreign Currency” above.

Accretion of Redeemable Noncontrolling Interest — Accretion of redeemable noncontrolling interest of $1.5 million for fiscal year 2016 related to put arrangements whereby the noncontrolling interest holders could require us to redeem the remaining shares of Airnorth (prior to repurchasing the remaining 15% of the outstanding shares in November 2015 discussed in Note 2) and Eastern Airways (prior to repurchasing the remaining 40% of the outstanding shares in January 2018 discussed Note 2) at a formula-based amount that is not considered fair value (the “redemption amount”). No accretion of redeemable noncontrolling interest was recorded in fiscal years 2018 or 2017. Redeemable noncontrolling interest was adjusted each period for comprehensive income, dividends attributable to the noncontrolling interest and changes in ownership interest, if any, such that the noncontrolling interest represented the proportionate share of Airnorth’s and Eastern Airways’ equity (the “carrying value”). Additionally, at each period end we were required to compare the redemption amount to the carrying value of the redeemable noncontrolling interest and record the redeemable noncontrolling interest at the higher of the two amounts, with a corresponding charge or credit directly to retained earnings. While this charge or credit did not impact net income (loss), it did result in a reduction or increase of income (loss) available to common shareholders in the calculation of earnings (loss) per share. In November 2015, we purchased the remaining 15% of the outstanding shares of Airnorth for A$7.3 million ($5.3 million) resulting in a reduction of $5.5 million to redeemable noncontrolling interest and an increase of $2.6 million to additional paid-in capital on our consolidated balance sheet. In January 2018, we acquired the remaining 40% of the outstanding shares of Eastern Airways for nominal consideration, resulting in a reduction of $6.1 million to redeemable noncontrolling interest and a corresponding increase to additional paid-in capital on our consolidated balance sheet.

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 for revenue from contracts with customers. The core principle of the new standard is to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration the entity expects to be entitled to in exchange for those goods or services through a five-step model. The new standard also requires enhanced disclosures regarding the nature, amount, timing, and uncertainty of revenue and the related cash flows arising from contracts with customers. This new standard is effective for the Company beginning on April 1, 2018. The standard is required to be adopted using either the full retrospective approach, with all prior periods presented adjusted, or the modified retrospective approach, with a cumulative adjustment to retained earnings on the balance sheet. We adopted this standard on April 1, 2018, utilizing the modified retrospective method. Under the modified retrospective method of adoption, prior year reported results are not recast; however, a cumulative-effect adjustment to retained earnings at April 1, 2018 is recorded, if applicable. In addition, quarterly disclosures will include comparative information for fiscal year 2018 financial statement line items under current guidance. To the extent applicable, upon adoption, we may be required to comply with expanded disclosure requirements, including the disaggregation of revenues to depict the nature and uncertainty of types of revenues, contract assets and liabilities, performance obligations, significant judgments and estimates affecting the amount and timing of revenue recognition, and determination of transaction prices. The adoption of this guidance did not result in a cumulative-effect adjustment on April 1, 2018.

In November 2015, the FASB issued accounting guidance that changed how deferred taxes are classified on an entity’s balance sheet. The accounting guidance requires that all deferred tax assets and liabilities, along with any related valuation allowance, be classified as noncurrent on the balance sheet. The new guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016 and early adoption is permitted. The guidance may be applied either prospectively, for all deferred tax assets and liabilities, or retrospectively. If applied prospectively, entities are required to include a statement that prior periods were not retrospectively adjusted. If applied retrospectively, entities are also required to include quantitative information about the effects of the change on prior periods. We adopted this accounting guidance using the prospective adjustment option effective April 1, 2017 and prior periods were not retrospectively adjusted. As of March 31, 2017, we had $0.1 million in current deferred taxes and $0.8 million in current deferred liabilities that were reclassified to noncurrent upon adoption of this accounting guidance.

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. We have not yet adopted this standard and are currently evaluating the effect this standard will have on our financial statements.

In March 2016, the FASB issued accounting guidance related to accounting for employee share-based payments. The accounting guidance is intended to simplify several aspects of accounting for share-based payment award transactions including income tax consequences, classification of awards as either equity or liabilities and classification on the statements of cash flows. This accounting guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016 and early adoption is permitted. We adopted this standard effective April 1, 2017. The requirements related to the tax consequences of share-based payments were applied prospectively and resulted in $1.8 million recorded as an increase to the income tax provision during fiscal year 2018. We elected to record forfeitures of share-based awards based on actual forfeitures, which did not have a material effect on our financial statements. The provisions related to the presentation of excess tax benefits on the statements of cash flows did not impact our financial statements as there was no excess tax benefit recorded for the periods presented. The provisions related to presenting employee taxes paid for withheld shares as a cash flow financing activity required us to revise our prior period consolidated statement of cash flows by $0.8 million and $2.2 million with a decrease in net cash used in operating activities and a corresponding decrease in net cash provided by financing activities for fiscal years 2017 and 2016, respectively. None of the other provisions of the pronouncement had a material effect on our financial statements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

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 assets 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 have not yet adopted this accounting guidance and are currently evaluating the effect this accounting guidance will have on our financial statements.

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 have not yet adopted this accounting guidance.

In March 2017, the FASB issued accounting guidance related to the presentation of net periodic pension cost and net periodic postretirement 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 postretirement 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 postretirement benefit in assets. We have not yet adopted this accounting guidance and are currently evaluating the effect this accounting guidance will have on our financial statements.

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 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 not yet adopted this accounting guidance and are currently evaluating the effect this accounting guidance will have on our financial statements.

In August 2017, the FASB issued new accounting guidance on derivatives and hedging, which amends and simplifies existing guidance in order to allow companies to more accurately present the economic effects of risk management activities in the financial statements. The two primary benefits resulting from these changes include the removal of the requirement to separately measure and report ineffectiveness and the ability to perform ongoing effectiveness assessments on a qualitative basis. This accounting guidance is effective for public business entities for fiscal years, and interim periods within those years, beginning after December 15, 2018, with earlier adoption permitted. We adopted this accounting guidance in fiscal year 2018. Since there were no active hedge accounting relationships as of the adoption date, there were no adjusting entries required to adjust on a modified retrospective basis.

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 March 2018, the FASB issued new accounting guidance to expand income tax accounting and disclosure guidance on accounting for the income tax effects of tax legislation commonly known as the Tax Cuts and Jobs Act (the “Act”) and among other things allows for a measurement period not to exceed one year for companies to finalize the provisional amounts recorded. We adopted this accounting guidance in fiscal year 2018. See Note 8 for further details.

Note 2 — VARIABLE INTEREST ENTITIES AND OTHER INVESTMENTS IN SIGNIFICANT AFFILIATES

VIEs

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 March 31, 2018, we had interests in four VIEs of which we are the primary beneficiary, which are described below, and had no interests in VIEs of which we are not the primary beneficiary.

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 holds all of the outstanding shares in Bristow Helicopters Limited (“Bristow Helicopters”). Bristow Aviation’s subsidiaries provide industrial aviation services to clients 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 ($127.7 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 $2.1 billion as of March 31, 2018.

The Company, Caledonia, the E.U. Investor and Bristow Aviation have entered into a shareholder agreement respecting, among other things, the composition 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 owns (1) at least 1,000,000 shares of common stock of the Company or (2) at least 49% of the total outstanding shares of Bristow Aviation.

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. 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 under the put/call agreement limiting our ability to exercise the put/call option is a requirement to consult with the Civil Aviation Authority (the “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 consolidated balance sheets as noncontrolling interest.

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 March 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% (prior to May 2004, the rate was fixed at 12%) by recognizing noncontrolling interest expense on our consolidated statements of operations, with a corresponding increase in noncontrolling interest on our consolidated balance sheets. Prepayments of the guaranteed return element of the call option are reflected as a reduction in noncontrolling interest on our 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.

Changes in the balance for the noncontrolling interest associated with Bristow Aviation are as follows (in thousands):

	Fiscal Year Ended March 31,

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 March 31, 2018. BHNL provides industrial aviation services to clients 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 its 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 an interest of 50.17%. PAAN provides industrial aviation services to clients in Nigeria.

The activities that most significantly impact PAAN’s economic performance relate to the day-to-day operation of PAAN, setting of 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.

Other Significant Affiliates — Consolidated

In addition to the VIEs discussed above, we consolidate the entities described below, which were less than 100% owned during fiscal years 2018, 2017 and/or 2016.

Airnorth — As of March 31, 2018, Bristow Helicopters Australia Pty Ltd. (“Bristow Helicopters Australia”) had a 100% interest in Airnorth, a regional fixed wing operator based in Darwin, Northern Territory, Australia with both scheduled and charter services that focus primarily on the energy and mining industries in northern and western Australia as well as international service to Dili, Timor-Leste. Airnorth’s fleet consists of 14 aircraft and its customer base includes many energy companies to which Bristow Group provides helicopter transportation services. In January 2015, Bristow Helicopters Australia acquired an 85% interest in Airnorth, for cash of A$30.3 million ($24.0 million). In November 2015, we purchased the remaining 15% of the outstanding shares of Airnorth for A$7.3 million ($5.3 million) resulting in a reduction of $5.5 million to redeemable noncontrolling interests and an increase of $2.6 million to additional paid-in capital on our consolidated balance sheet. The terms of the purchase agreement for Airnorth included a potential earn out consideration of up to A$17.0 million ($13.0 million) to be paid over four years based in part on the achievement of specified financial performance thresholds and continued employment by the selling shareholders. A portion of the first year earn-out payment of $1.5 million was paid during fiscal year 2016 as Airnorth achieved agreed performance targets. Airnorth did not achieve the performance targets for the second year earn-out payment. In addition, we entered into an agreement with the other shareholders of Capiteq Limited that granted us the right after six months to buy all of their shares (and granted them the right after three years to require us to buy all of their shares) and included transfer restrictions and other customary provisions.

Prior to the acquisition of the remaining 15% of outstanding shares of Airnorth in November 2015, redeemable noncontrolling interests included the third-party noncontrolling interests in Airnorth. The third-party noncontrolling interest holders held a written put option, which allowed them to sell their noncontrolling interest to Bristow Helicopters Australia at any time after the end of the third year after acquisition. In addition to the written put option, Bristow Helicopters Australia held a perpetual call option to acquire the noncontrolling interest after six months. Under each of these alternatives, the exercise price would be based on a contractually defined multiple of cash flows formula (the “Airnorth Redemption Value”), which is not a fair value measurement, and was payable in cash. As the written put option was redeemable at the option of the noncontrolling interest holders, and not solely within Bristow Helicopters Australia’s control, the noncontrolling interest in Airnorth was classified in redeemable noncontrolling interests between the stockholders’ investment and liabilities sections of the consolidated balance sheets. The initial carrying amount of the noncontrolling interest was the fair value of the noncontrolling interest as of the acquisition date.

The noncontrolling interest was adjusted each period for comprehensive income and dividends attributable to the noncontrolling interest and any changes in Bristow Helicopters Australia’s ownership interest in Airnorth, if any. An additional adjustment to the carrying value of the noncontrolling interest was required if the Airnorth Redemption Value exceeded the current carrying value. Changes in the carrying value of the noncontrolling interest related to a change in the Airnorth Redemption Value would be recorded against permanent equity and would not affect net income. While there was no impact on net income, the redeemable noncontrolling interest impacted our calculation of earnings per share. Utilizing the two-class method, we adjusted the numerator of the earnings per share calculation to reflect the changes in the excess, if any, of the Airnorth Redemption Value over the greater of (1) the noncontrolling interest carrying amount or (2) the fair value of the noncontrolling interest on a quarterly basis.

Changes in the balance for the redeemable noncontrolling interest related to Airnorth are as follows (in thousands):

Eastern Airways — As of March 31, 2018, Bristow Helicopters had a 100% interest in Eastern Airways, a regional fixed wing operator based at Humberside Airport located in North Lincolnshire, England with both charter and scheduled services targeting U.K oil and gas industry transportation. In February 2014, Bristow Helicopters acquired a 60% interest in Eastern Airways. In January 2018, Bristow Helicopters acquired the remaining 40% of the outstanding shares of Eastern Airways for nominal consideration. Eastern Airways operates 34 fixed wing aircraft and provides technical support for two fixed wing aircraft. The terms of the purchase agreement for Eastern Airways included potential earn-out consideration of up to £6 million ($7.5 million) to be paid over a three-year period based on the achievement of specified financial performance thresholds through March 31, 2017. None of the earn-out targets were achieved. In addition, Bristow Helicopters entered into agreements with the other shareholders of Eastern Airways that grant Bristow Helicopters the right to buy all of the Eastern Airways shares (and grant them the right after seven years to require Bristow Helicopters to buy all of their shares) and include transfer restrictions and other customary provisions.

The third-party noncontrolling interest holders hold a written put option, which will allow them to sell their noncontrolling interest to Bristow Helicopters at any time after the end of the seventh year after acquisition. In addition to the written put option, Bristow Helicopters holds a perpetual call option to acquire the noncontrolling interest at any time. Under each of these alternatives, the exercise price will be based on a contractually defined multiple of cash flows formula (the “Eastern Redemption Value”), which is not a fair value measurement, and is payable in cash. As the written put option is redeemable at the option of the noncontrolling interest holders, and not solely within Bristow Helicopters control, the noncontrolling interest in Eastern Airways is classified in redeemable noncontrolling interests between the stockholders’ investment and liabilities sections of the consolidated balance sheets. The initial carrying amount of the noncontrolling interest was the fair value of the noncontrolling interest as of the acquisition date.

Prior to our acquisition of the remaining 40% outstanding shares in fiscal year 2018, Eastern Airways was consolidated based on the rights to manage the day-to-day operations of the company which were granted under a shareholders’ agreement and our ability to buy all of their Eastern Airways shares under a put/call agreement.

Aviashelf — Bristow Aviation has an indirect 48.5% interest in Aviashelf Aviation Co. (“Aviashelf”), a Russian helicopter company. Additionally, we own 60% of two U.K. joint venture companies, Bristow Helicopters Leasing Ltd. and Sakhalin Bristow Air Services Ltd. These two U.K. companies lease aircraft to Aviashelf which holds the client contracts for our Russian operations. Aviashelf is consolidated based on the ability of certain consolidated subsidiaries of Bristow Aviation to control the vote on a majority of the shares of Aviashelf, rights to manage the day to day operations of the company which were granted under a shareholders’ agreement, and our ability to acquire an additional 8.5% interest in Aviashelf under a put/call option agreement.

Other Significant Affiliates — Unconsolidated

We have investments in other significant unconsolidated affiliates as described below.

Cougar — We own a 25% voting interest and a 40% economic interest in Cougar Helicopters Inc. (“Cougar”), the largest offshore energy and SAR helicopter service provider in Canada. Cougar’s operations are primarily focused on serving the offshore oil and gas industry off Canada’s Atlantic coast and in the Arctic. Cougar operates eight helicopters leased from us on a long-term basis. We also lease maintenance and SAR facilities located in St. John’s, Newfoundland and Labrador and Halifax, Nova Scotia to Cougar on a long-term basis. The terms of the purchase agreement for Cougar include a potential earn-out of $40 million payable over three years based on Cougar achieving certain agreed performance targets. The first year and second year earn-out payments of $6.0 million and $8.0 million were paid in March 2014 and April 2015, respectively, as Cougar achieved agreed performance targets. The third year earn-out was achieved as Cougar achieved agreed performance targets of which $10 million was paid in April 2016 and $16 million was paid in April 2017. The fair value of the earn-out was $16.0 million as of March 31, 2017 and is included in short-term borrowings and current maturities of long-term debt on our consolidated balance sheet. The investment in Cougar is accounted for under the equity method. As of March 31, 2018 and 2017, the investment in Cougar was $54.0 million and $56.9 million, respectively, and is included on our consolidated balance sheets in investment in unconsolidated affiliates. Due to timing differences in our financial reporting requirements, we record our share of Cougar’s financial results in earnings from unconsolidated affiliates on a three-month delay. Additionally, we have leased aircraft from VIH Aviation Group, which is a related party due to common owners of Cougar, and paid lease fees of $19.3 million, $12.5 million and $6.5 million in fiscal years 2018, 2017 and 2016, respectively. Additionally, we paid $0.5 million and $2.6 million in fiscal years 2017 and 2016, respectively, to VIH Aerospace Inc., another related party with common owners of Cougar, for SAR and other equipment. In July 2016 we began leasing a facility in Galliano, Louisiana from VIH Helicopters USA, Inc., another related party with common owners of Cougar, and paid $0.2 million and $0.1 million in lease fees during fiscal years 2018 and 2017, respectively.

Líder — 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. Líder’s fleet has 41 helicopters and 20 fixed wing aircraft (including owned and managed aircraft). The investment in Líder is accounted for under the equity method. As of March 31, 2018 and 2017, the investment in Líder was $62.3 million and $143.5 million, respectively, and is included in our consolidated balance sheets in investment in unconsolidated affiliates. As discussed in Note 1, we recorded an $85.7 million impairment to our investment in Líder in fiscal year 2018.

PAS — We have a 25% interest in Petroleum Air Services (“PAS”), an Egyptian corporation that provides helicopter and fixed wing transportation to the offshore energy industry in Egypt. Additionally, spare fixed wing capacity is chartered to tourism operators. PAS owns 48 aircraft. PAS is accounted for under the cost method as we are unable to exert significant influence over its operations.

Other — Historically, in addition to the expansion of our business through purchases of new and used aircraft, we have also established new joint ventures with local partners or purchased significant ownership interests in companies with ongoing helicopter operations, particularly in countries where we have no operations or our operations are limited in scope, and we continue to evaluate similar opportunities which could enhance our operations. Where we believe that it is probable that an equity method investment will result, the costs associated with such investment evaluations are deferred and included in investment in unconsolidated affiliates on the consolidated balance sheets. For each investment evaluated, an impairment of deferred costs is recognized in the period in which we determine that it is no longer probable an equity method investment will result. As of March 31, 2018 and 2017, we had no amounts in investment in unconsolidated affiliates in the process of being evaluated.

⁽¹⁾  During fiscal year 2016, we took delivery of two aircraft that were purchased using short-term debt borrowings for the final payments of the aircraft. As of March 31, 2017, the short-term borrowings for these aircraft have been paid.

⁽²⁾  During fiscal years 2018, 2017 and 2016, we spent $2.3 million, $71.4 million and $202.7 million, respectively, on progress payments for aircraft to be delivered in future periods.

The following table presents details on the aircraft sold or disposed of and impairments on assets held for sale during fiscal years 2018, 2017 and 2016:

⁽¹⁾  During fiscal year 2016, three of these aircraft were sold and leased back and we received $29.2 million in proceeds for the aircraft. We did not enter into any sale leasebacks during fiscal years 2017 and 2018.

⁽²⁾  Includes $6.5 million impairment of the Bristow Academy disposal group for fiscal year 2018.

In addition to capital expenditures and sale or disposal of assets, the following items impacted property and equipment during fiscal year 2018:

• We transferred 4 aircraft to held for sale and reduced property and equipment by $9.3 million.

In addition to capital expenditures and sale or disposal of assets, the following items impacted property and equipment during fiscal year 2017:

• We recorded accelerated depreciation of $10.4 million on 11 medium aircraft operating in our Europe Caspian, Americas and Africa regions as our management decided to exit these model types earlier than originally anticipated. In certain instances the salvage values of some aircraft were also adjusted to reflect our expectation of sales values in the current market.

• We transferred 12 aircraft to held for sale and reduced property and equipment by $19.7 million.

BRISTOW GROUP INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

In addition to capital expenditures and sale or disposal of assets, the following items impacted property and equipment during fiscal year 2016:

• We recorded accelerated depreciation of $28.7 million on 18 medium, four large and one fixed wing aircraft operating in our Europe Caspian, Americas, Africa and Asia Pacific regions as our management decided to exit these model types earlier than originally anticipated. In certain instances the salvage values of some aircraft were also adjusted to reflect our expectation of sales values in the current market.

• We took delivery and entered into leases for the remaining two aircraft related to the deferred sale leaseback and removed a total of $75.8 million and $74.3 million, respectively, from construction in progress and deferred sale leaseback advance on our consolidated balance sheet. See Note 1 for further details on the deferred sale leaseback advance.

• We took delivery of two large aircraft which we purchased using short-term debt borrowings for the final payments of the aircraft of $24.4 million.

• We transferred 35 aircraft to held for sale and reduced property and equipment by $83.6 million.

During fiscal years 2018, 2017 and 2016, we saw a deterioration in market sales for aircraft resulting mostly from an increase in idle aircraft and reduced demand across the offshore energy market. While other markets exist for certain aircraft model types, including utility, firefighting, government, VIP transportation and tourism, the market for certain model type aircraft slowed. As a result of these market changes, changes in estimated salvage values of our fleet of operational aircraft and other changes in the timing of exiting certain aircraft from our operations, we recorded impairments and additional depreciation expense discussed above. For further details, see Note 1 for a discussion on impairments of property and equipment.

Assets Held for Sale

Assets held for sale are classified as current assets on our consolidated balance sheets and recorded at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. As of March 31, 2018 and 2017, we had 11 and 20 aircraft, for $30.3 million and $38.2 million, classified as held for sale, respectively. We intend to sell or otherwise dispose of these assets during the next fiscal year. As presented in the table above, we recorded impairment charges of $15.9 million, $12.5 million and $29.6 million to reduce the carrying value of eight, 14 and 16 aircraft held for sale during fiscal years 2018, 2017 and 2016, respectively. These impairment charges were included in loss on disposal of assets in the consolidated statements of operations.

The impairment charges recorded on held for sale aircraft during fiscal years 2018, 2017 and 2016 related primarily to older model aircraft types our management decided to dispose of earlier than originally anticipated in addition to the impact of changes in expected sales prices in the aircraft aftermarket resulting from the oil and gas market downturn.

On November 1, 2017, we sold our 100% interest in Bristow Academy, including all of its aircraft, for a minimum of $1.5 million to be received over a maximum of four years with potential additional consideration based on Bristow Academy’s financial performance. The sale of this non-core business resulted in total charges recorded in the fiscal year 2018 of $7.2 million, which resulted from the combined loss on the sale and related impairment of assets included in loss on disposal of assets on our consolidated statement of operations. Bristow Academy is included in Corporate and other in Note 11.

OEM Cost Recoveries

During fiscal year 2018, we reached agreements with OEMs to recover $136.0 million related to ongoing aircraft issues, of which $125.0 million was realized and resulted in an increase in cash. 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. 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 have allocated the $94.5 million as a reduction in carrying value by reducing the historical acquisition value of each affected aircraft on a pro-rata basis utilizing the historical acquisition value of the aircraft. We revised our salvage values for each affected aircraft by reducing the historical acquisition value by the applicable amount and applying our stated salvage value percentage for owned aircraft of 50%. 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 will result in a reduction of depreciation expense of $8.5 million during fiscal year 2019, $8.4 million during fiscal year 2020, $5.6 million during fiscal year 2021 and $21.3 million during fiscal year 2022 and beyond. For the leased aircraft, we will recognize the remaining deferred liability of $13.9 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 $7.9 million during fiscal year 2019, $4.0 million during fiscal year 2020 and $2.0 million during fiscal year 2021.

During May 2018, we realized 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. We expect to realize the $11.0 million recovery in earnings during fiscal year 2019 as follows: $7.6 million increase in revenue and $1.1 million decrease in direct cost in the first quarter, $1.0 million decrease in direct cost in the second quarter, $1.0 million decrease in direct cost in the third quarter and $0.3 million decrease in direct cost in the fourth quarter. 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 that we have recovered from the OEM.

Short-term borrowings reclassification — 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 the Explanatory Note included elsewhere in this Annual Report, on May 11, 2019, 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. Each of the commencement of the Chapter 11 Cases and the delivery of this Amended 10-K 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 March 31, 2018 should be reclassified from long-term to short-term within this Amended 10-K on our consolidated balance sheet.

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 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.

8.75% Senior Secured Notes — On March 6, 2018, we issued and sold $350 million of 8.75% Senior Secured Notes in a private offering to eligible purchasers pursuant to Rule 144A and Regulation S under the Securities Act of 1933, as amended, for proceeds of $346.6 million and simultaneously entered into an indenture (the “Indenture”) with U.S. Bank National Association, as trustee and as collateral agent. The 8.75% Senior Secured Notes were initially fully and unconditionally guaranteed, jointly and severally, on a senior secured basis by certain of our U.S. subsidiaries (the “Guarantor Subsidiaries”) and will be secured by first priority security interests on substantially all of the tangible and intangible personal property of Bristow Group Inc. and the Guarantor Subsidiaries (other than certain excluded assets) (the “Collateral”) as collateral security for their obligations under the 8.75% Senior Secured Notes, subject to certain permitted encumbrances and exceptions. Certain of the security interests were

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

granted in connection with the execution and delivery of the Indenture, while security interests anticipated to cover approximately 77 aircraft will be granted within the periods described in the Indenture.

The 8.75% Senior Secured Notes bear interest at a rate of 8.75% per year, payable semi-annually in arrears on March 1 and September 1 of each year, beginning on September 1, 2018. The 8.75% Senior Secured Notes will mature on March 1, 2023, subject to earlier mandatory redemption if more than $125 million principal amount of the 6¼% Senior Notes due 2022 (the “6¼% Senior Notes”) plus the principal amount of any indebtedness incurred to refinance the 6¼% Senior Notes that matures or is required to be repaid prior to June 1, 2023 remains outstanding as of June 30, 2022. We may redeem all or a portion of the 8.75% Senior Secured Notes at any time on or after March 1, 2020 at the applicable redemption price, plus accrued and unpaid interest, if any, to the redemption date. At any time prior to March 1, 2020, we may redeem all or a portion of the 8.75% Senior Secured Notes at a price equal to 100% of the principal amount of 8.75% Senior Secured Notes to be redeemed plus a “make-whole” premium, plus accrued and unpaid interest, if any, to the redemption date. In addition, on one or more occasions, on or prior to March 1, 2020, we may redeem up to 35% of the aggregate principal amount of the 8.75% Senior Secured Notes at a redemption price equal to 108.75% of the principal amount of the 8.75% Senior Secured Notes to be redeemed, plus accrued and unpaid interest, if any, to the redemption date, with an amount of cash not greater than the net cash proceeds of certain qualified equity offerings by us.

The Indenture contains customary covenants that, among other things, limit our ability to incur additional liens or financial indebtedness and to sell or otherwise transfer the Collateral, including the pledged aircraft. The Indenture also contains customary events of default. If an event of default occurs and is continuing, the Trustee or the holders of at least 25% in principal amount of the then outstanding 8.75% Senior Secured Notes may declare the unpaid principal of, and any premium and accrued and unpaid interest on, all the 8.75% Senior Secured Notes then outstanding to be due and payable immediately. In case of certain events of bankruptcy, insolvency or reorganization with respect to Bristow Group Inc., any Guarantor Subsidiary or any significant subsidiary, all of the principal of and accrued and unpaid interest on the 8.75% Senior Secured Notes will automatically become due and payable. Upon a change of control (as defined in the Indenture), we will be required to make an offer to repurchase all or any part of each 8.75% Senior Secured Notes at an offer price in cash equal to 101% of the aggregate principal amount, plus accrued and unpaid interest, if any, to the date of repurchase.

The proceeds of the 8.75% Senior Secured Notes were used, among other things, to repay the remaining obligations of the $350 million term loan (the “Term Loan”) discussed below, to cash collateralize certain outstanding letters of credit existing under the $400 million revolving credit facility with a subfacility of $50 million for letters of credit (the “Revolving Credit Facility”) discussed below and for general corporate purposes.

4½% Convertible Senior Notes — On December 18, 2017, we issued and sold $143.8 million of 4½% Convertible Senior Notes due 2023 (the “4½% Convertible Senior Notes”). The 4½% Convertible Senior Notes are our unsecured senior obligations and are jointly and severally guaranteed on a senior unsecured basis by the Guarantor Subsidiaries. The 4½% Convertible Senior Notes bear interest at a rate of 4.50% per year and interest is payable on June 1 and December 1 of each year, beginning on June 1, 2018. The 4½% Convertible Senior Notes mature on June 1, 2023 and may not be redeemed by us prior to maturity.

The 4½% Convertible Senior Notes are convertible into cash, shares of our common stock or a combination of cash and shares of our common stock, at our election. We have initially elected combination settlement. The initial conversion price of the 4½% Convertible Senior Notes is approximately $15.64 (subject to adjustment in certain circumstances), based on the initial conversion rate of 63.9488 common shares per $1,000 principal amount of 4½% Convertible Senior Notes. Prior to December 1, 2022, the 4½% Convertible Senior Notes will be convertible only upon the occurrence of certain events and during certain periods, and thereafter, until the close of business on the second scheduled trading day immediately preceding the maturity date. The 4½% Convertible Senior Notes are senior unsecured obligations. As of March 31, 2018, the if-converted value of the 4½% Convertible Senior Notes did not exceed the principal balance.

The proceeds of the 4½% Convertible Senior Notes were used to repay $89.6 million of the Term Loan as discussed below and to pay the $10.1 million cost of the convertible note hedge transaction described below, with the remainder available for general corporate purposes.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Accounting standards require that convertible debt which may be settled in cash upon conversion (including partial cash settlement) be accounted for with a liability component based on the fair value of similar nonconvertible debt and an equity component based on the excess of the initial proceeds from the convertible debt over the liability component. Such excess represents proceeds related to the conversion option and is recorded as additional paid-in capital. The liability is recorded at a discount, which is then amortized as additional non-cash interest expense over the term of the 4½% Convertible Senior Notes. The balances of the debt and equity components of the 4½% Convertible Senior Notes as of March 31, 2018 are as follows (in thousands):

Equity component - net carrying value (1)	$	36,778
Debt component:
Face amount due at maturity	$	143,750
Unamortized discount	(36,353		)
Debt component - net carrying value	$	107,397

_____________ 

⁽¹⁾ Net of equity issuance costs of $1.0 million.

The remaining debt discount is being amortized to interest expense over the term of the 4½% Convertible Senior Notes using the effective interest rate. The effective interest rate for the fiscal year 2018 was 11.0%. Interest expense related to our 4½% Convertible Senior Notes for fiscal year 2018 was as follows (in thousands):

Contractual coupon interest	$	1,851
Amortization of debt discount	1,454
Total interest expense	$	3,305

Convertible Note Call Spread Overlay — Concurrent with the issuance of the 4½% Convertible Senior Notes, we entered into privately negotiated convertible note hedge transactions (the “Note Hedge Transactions”) and warrant transactions (the “Warrant Transactions”) with each of Credit Suisse Capital LLC, Barclays Bank PLC, Citibank, N.A. and JPMorgan Chase Bank, National Association (the “Option Counterparties”). These transactions represent a Call Spread Overlay, whereby the cost of the Note Hedge Transactions we purchased to cover the cash outlay upon conversion of the 4½% Convertible Senior Notes was reduced by the sales price of the Warrant Transactions. Each of these transactions is described below.

The Note Hedge Transactions cost an aggregate $40.4 million and are expected generally to reduce the potential dilution and/or offset the cash payments we are required to make in excess of the principal amount upon conversion of the 4½% Convertible Senior Notes in the event that the market price of our common stock is greater than the strike price of the Note Hedge Transactions, which is initially $15.64 (subject to adjustment), corresponding approximately to the initial conversion price of the 4½% Convertible Senior Notes. The Note Hedge Transactions have been accounted for by recording the cost as a reduction to additional paid-in capital.

We received proceeds of $30.3 million for the Warrant Transactions, in which we sold net-share-settled warrants to the Option Counterparties in an amount equal to the number of shares of our common stock initially underlying the 4½% Convertible Senior Notes, subject to customary anti-dilution adjustments. The strike price of the warrants is $20.02 per share (subject to adjustment), which is 60% above the last reported sale price of our common stock on the New York Stock Exchange on December 13, 2017. The Warrant Transactions could have a dilutive effect to our stockholders to the extent the market price per share of our common stock, as measured under the terms of the Warrant Transactions, exceeds the applicable strike price of the warrants. The Warrant Transactions have been accounted for by recording the proceeds received as additional paid-in capital.

The Note Hedge Transactions and the Warrant Transactions are separate transactions, in each case entered into by us with the Option Counterparties, and are not part of the terms of the 4½% Convertible Senior Notes and will not affect any holder’s rights under the 4½% Convertible Senior Notes.

6¼% Senior Notes — On October 12, 2012, we completed an offering of $450 million of the 6¼% Senior Notes. The 6¼% Senior Notes are senior unsecured obligations and are jointly and severally guaranteed on a senior unsecured basis by the Guarantor Subsidiaries. The indenture for our 6¼% Senior Notes includes restrictive covenants which limit, among other things, our ability to incur additional debt, issue disqualified stock, pay dividends, repurchase stock, invest in other entities, sell assets, incur additional liens or security, merge or consolidate the Company and enter into transactions with affiliates. Interest on the 6¼% Senior Notes is payable on April 15 and October 15 of each year and the 6¼% Senior Notes mature on October 15, 2022. We may redeem any of the 6¼% Senior Notes at any time, in whole or part, in cash, at certain redemption prices plus accrued and unpaid interest, if any, to the date of redemption. We incurred financing fees of $7.4 million, that are included as deferred financing fees in other

assets in the consolidated balance sheets which we will amortize as interest expense in the consolidated statements of operations over the life of the 6¼% Senior Notes.

Revolving Credit Facility and Term Loan — Our amended and restated revolving credit and term loan agreement, included the Revolving Credit Facility and the Term Loan (together with the Revolving Credit Facility and the Term Loan Credit Facility described below, the “Senior Credit Facilities”).

During fiscal year 2018, we had borrowings of $174.8 million under the Revolving Credit Facility and made payments of $313.9 million to fully repay borrowings under the Revolving Credit Facility. Additionally, during fiscal year 2018 we made payments of $261.9 million to fully repay our borrowings under the Term Loan. In March 2018, we terminated both the Revolving Credit Facility and Term Loan and cash collateralized all then-outstanding letters of credit issued thereunder.

Term Loan Credit Facility — On November 5, 2015, we entered into a senior secured term loan credit agreement providing for $200 million of term loan commitments (the “Term Loan Credit Facility”).

Borrowings under the Term Loan Credit Facility were repaid in full and the facility was terminated in October 2017.

Lombard Debt — On November 11, 2016, certain of our subsidiaries entered into two, seven-year British pound sterling funded secured equipment term loans for an aggregate $200 million U.S. dollar equivalent with Lombard North Central Plc, a part of the Royal Bank of Scotland (the “Lombard Debt”). In December 2016, the first loan amount of $109.9 million (GBP 89.1 million) funded and the borrower prepaid scheduled principal payments of $4.5 million (GBP 3.7 million). The proceeds from this financing were used to finance the purchase by the borrower thereunder of three SAR aircraft utilized for our U.K. SAR contract from a subsidiary. In January 2017, the second loan amount of $90.1 million (GBP 72.4 million) funded. The proceeds from this financing were used to finance the purchase by the borrower thereunder of five SAR aircraft utilized for our U.K. SAR contract from a subsidiary. The borrowers’ respective obligations under the financings are guaranteed by the Company, and each financing is secured by the aircraft purchased by the applicable borrower with the proceeds of its loan. The credit agreements governing the Lombard Debt include covenants, including requirements to maintain, register and insure the respective SAR aircraft secured thereunder, and restrictions on the respective borrower thereunder to incur additional liens on or sell the respective SAR aircraft secured thereunder (except to the Company and its subsidiaries). Borrowings under the financings bear interest at an interest rate equal to the ICE Benchmark Administration Limited LIBOR (or the successor thereto) plus 2.25% per annum. The weighted-average interest rate was 2.96% and 2.57% as of March 31, 2018 and 2017, respectively. The financing which funded in December 2016 matures in December 2023 and the financing which funded in January 2017 matures in January 2024.

Macquarie Debt — On February 1, 2017, one of our wholly-owned subsidiaries entered into a term loan credit agreement for a $200 millionfive-year secured equipment term loan with Macquarie Bank Limited (the “Macquarie Debt”). In conjunction with closing and funding under such term loan, we have agreed to lease five helicopters for lease terms ranging from 60 to 63 months from Wells Fargo Bank Northwest, N.A., acting as owner trustee for Macquarie Aerospace Inc., an affiliate of Macquarie Bank Limited. The borrower’s obligations under the credit agreement are guaranteed by the Company and secured by 20 oil and gas aircraft. The financing funded on March 7, 2017. Borrowings under the financing bear interest at an interest rate equal to the ICE Benchmark Administration Limited LIBOR (or the successor thereto) plus 5.35% per annum. The interest rate was 7.00% and 6.24% as of March 31, 2018 and 2017, respectively. The proceeds from the financing were used to repay $154.1 million of the Term Loan Credit Facility and $45.9 million of the Term Loan.

The credit agreement governing the Macquarie Debt includes covenants, including requirements to maintain, register and insure the respective aircraft secured thereunder, and restrictions on the respective borrower thereunder to incur additional liens on or sell the respective aircraft secured thereunder (except to the Company and its subsidiaries). The Macquarie Debt matures in March 2022.

PK Air Debt — On July 17, 2017, a wholly-owned subsidiary entered into a term loan credit agreement with PK AirFinance S.à r.l., as agent, and PK Transportation Finance Ireland Limited, as lender, and other lenders from time to time party thereto, which provided for commitments in an aggregate amount of up to $230 million to make up to 24 term loans, each of which was made in respect of an aircraft pledged as collateral for all of the term loans. The term loans are also secured by a pledge of all shares of the borrower and any other assets of the borrower and are guaranteed by the Company. The financing funded in two tranches in September 2017 and proceeds were used to repay $17.0 million of the Term Loan Credit Facility, $93.7 million of the Term Loan and $103.0 million of the Revolving Credit Facility.

Each term loan bears interest at an interest rate equal to, at the borrower’s option, a floating rate of one-month LIBOR plus a margin of 5% per annum (the “Margin”), subject to certain costs of funds adjustments, determined two business days before the borrowing date of each term loan, or a fixed rate based on a notional interest rate swap of 12 30-day months in respect of such

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

term loan with a floating rate of interest based on one-month LIBOR, plus the Margin. The weighted-average interest rate was 6.79% as of March 31, 2018.

The borrower is required to repay each term loan on an annuity basis, payable monthly in arrears starting on the seventh month following the date of the borrowing of such term loan, with a final payment of 53% of the initial amount of such term loan due on the 70th month following the date of the borrowing of such term loan.

In connection with the PK AirFinance term loan credit agreement, the borrower guarantees certain of its direct parent’s obligations under existing aircraft operating leases up to a capped amount.

AirnorthDebt—Airnorth’s outstanding debt includes interest bearing term loans of $13.8 million as of March 31, 2018. The term loans primarily relate to the purchase of aircraft, have a remaining term of approximately two to six years, and consist of a term loan with interest at LIBOR plus a margin of 2.85% and two term loans each with a fixed rate of 3.1% plus the Reserve Bank of Australia cash rate of 2.0%. The term loans have customary covenants, including certain financial covenants, and varying principal payments.

Eastern Airways Debt —Eastern Airways’ outstanding debt includes interest bearing term loans and borrowings under a revolving credit facility totaling $14.5 million as of March 31, 2018. The term loans were used to refinance other Eastern indebtedness in October 2015 and bear interest at LIBOR plus a margin of 1.75%. The interest rate on the term loans was 2.23% as of March 31, 2018. These term loans have quarterly principal payments and mature on August 31, 2018. Borrowings under the revolving credit facility are used for general corporate, working capital and capital expenditure purposes, and bear interest at LIBOR plus a margin of 1.75%. All outstanding obligations under the revolving credit facility will mature on August 31, 2018.

Other Debt — Other debt primarily includes amounts payable relating to the third year earn-out payment for our investment in Cougar totaling $16.0 million that was paid in April 2017.

Other Matters — Aggregate annual maturities (which excludes unamortized discount of $36.4 million and unamortized debt issuance costs of $27.5 million) for all debt for the next five fiscal years and thereafter are as follows (in thousands):

Note 5 — 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 as its fair value.

The following table summarizes the assets as of March 31, 2018, valued at fair value on a non-recurring basis (in thousands):

	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Balance as of March 31, 2018		Total Loss for Fiscal Year 2018

The following table summarizes the assets as of March 31, 2017, valued at fair value on a non-recurring basis (in thousands):

	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Balance as of March 31, 2017		Total Loss for Fiscal Year 2017
Inventories	$	—	$	46,568	$	—	$	46,568	$	(7,572	)

Total assets	$	—	$	84,814	$	19,798	$	104,612	$	(28,728	)

The fair value of inventories using Level 2 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 timeframe 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. See Note 1 for further discussion of the impairment of inventories.

The fair value of assets held for sale using Level 2 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. See Note 3 for details on assets held for sale.

The fair value of investment in affiliates is estimated using a variety of valuation methods, including the income and market approaches. These estimates of fair value include unobservable inputs, representative of Level 3 fair value measurement, including assumptions related to future performance, such as projected demand for services and rates. For further details on our investment in unconsolidated affiliates, see Notes 1 and 2.

The fair value of other intangible assets and goodwill is estimated using a variety of valuation methods, including the income and market approaches. These estimates of fair value include unobservable inputs, representative of Level 3 fair value measurement, including assumptions related to future performance, such as projected demand for our services and rates. For further details on other intangible assets and goodwill, see Note 1.

The rabbi trust investments consist of cash and mutual funds whose fair value are based on quoted prices in active markets for identical assets, and are designated as Level 1 within the valuation hierarchy. The rabbi trust holds investments related to our non-qualified deferred compensation plan for our senior executives as discussed in Note 9. The derivative financial instrument consists of foreign currency put option contracts whose fair value is determined by quoted market prices of the same or similar instruments, adjusted for counterparty risk.

Note 6 — 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, we entered into foreign currency put option contracts of £5 million per month through November 2018 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.

The following table presents the balance sheet location and fair value of the portions of our derivative instruments that were designated as hedging instruments as of March 31, 2018 (in thousands):

	Derivatives designated as hedging instruments under ASC 815		Derivatives not designated as hedging instruments under ASC 815		Gross amounts of recognized assets and liabilities		Gross amounts offset in the Balance Sheet		Net amounts of assets and liabilities presented in the Balance Sheet

Operating Leases — We have non-cancelable operating leases in connection with the lease of certain equipment, land and facilities, including leases for aircraft. Rental expense incurred under all operating leases was $208.7 million, $212.6 million and $211.8 million in fiscal years 2018, 2017 and 2016, respectively. Rental expense incurred under operating leases for aircraft was $181.3 million, $188.2 million and $184.0 million in fiscal years 2018, 2017 and 2016, respectively. As of March 31, 2018, aggregate future payments under all non-cancelable operating leases that have initial or remaining terms in excess of one year, including leases for 86 aircraft, are as follows (in thousands):

In fiscal year 2016, we sold three aircraft for $29.2 million and entered into separate agreements to lease these aircraft back. We did not enter into any sale leasebacks during fiscal years 2018 or 2017.

The aircraft leases range from base terms of up to 181 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. These leases are included in the amounts disclosed above. 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 March 31, 2018:

End of Lease Term	Number of Aircraft
Fiscal year 2019 to fiscal year 2020	43
Fiscal year 2021 to fiscal year 2023	32
Fiscal year 2024 to fiscal year 2026	11
	86

Employee Agreements — Approximately 54% of our employees are represented by collective bargaining agreements and/or unions with 86% of these employees being represented by collective bargaining agreements and/or unions that have expired or will expire in one year. These agreements generally include annual escalations of up to 3%. Periodically, certain groups of our employees who are not covered by a collective bargaining agreement consider entering into such an agreement. We also have employment agreements with members of senior management. For discussion on separation programs between the Company and its employees, see Note 9.

Environmental Contingencies — The U.S. Environmental Protection Agency (the “EPA”) has in the past notified us that we are a potential responsible party, or PRP, at three former waste disposal facilities that are on the National Priorities List of contaminated sites. Under the federal Comprehensive Environmental Response, Compensation and Liability Act, also known as the Superfund law, persons who are identified as PRPs may be subject to strict, joint and several liability for the costs of cleaning up environmental contamination resulting from releases of hazardous substances at National Priorities List sites. 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.

Other Purchase Obligations — As of March 31, 2018, we had $48.3 million of other purchase obligations representing 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.

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.

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 the Norway Aviation Agency issued safety and operational directives that detail the conditions to apply for safe return to service of H225LP and AS332L2 model aircraft, where operators wish to do so. We continue not to operate for commercial purposes our 24 H225LP model aircraft. We are carefully evaluating next steps and demand for the H225LP model aircraft in our oil and gas and SAR operations worldwide, with the safety of passengers and crews remaining our highest priority.

Separately, our efforts to successfully integrate AW189 aircraft into service for the U.K. SAR contract have been delayed due to a product improvement plan with the aircraft. As a result, the acceptance of four AW189 aircraft will be pushed to later dates. We 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 in May 2018. For further details on the accounting for these recoveries, see Note 3.

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 March 31, 2018 to be approximately $5 million to $6 million.

In connection with the Bristow Norway acquisition in October 2008, we granted the former partner in this joint venture an option that if exercised would require us to acquire up to five aircraft at fair value upon the expiration of the lease terms for such aircraft. One of the options was exercised in December 2009 and two of the options expired. The remaining aircraft leases expire in August 2018. We are currently unable to estimate the fair value of these aircraft. While we do not currently expect to be required to purchase these aircraft, the former joint venture partner has until May 31, 2018 to notify us. If the joint venture partner does not exercise its option, it is our intent to return the aircraft after the leases expire in August 2018.

We are a defendant in certain claims and litigation arising out of operations in the normal course of business. In the opinion of management, uninsured losses, if any, will not be material to our financial position, results of operations or cash flows.

Note 8 — TAXES

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 (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 that will be applicable to us beginning in fiscal year 2019: (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. 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. Consistent with guidance in SAB 118, we recorded provisional amounts for the transition tax on undistributed earnings of $52.9 million, which was partially offset by foreign tax credits of $22.6 million. We also recorded $53.0 million tax benefit as a result of the revaluation of our net deferred tax liabilities. The provisional amounts incorporate assumptions made based upon our current interpretation of the Act and may change as we receive additional clarification and implementation guidance.

We are continuing to analyze additional information to determine the final impact as well as other impacts of the Act. Any adjustments recorded to the provisional amounts will be included in income from operations as an adjustment to our fiscal year 2019 financial statements.

Companies may use foreign tax credits to offset the U.S. income taxes due on income earned from foreign sources. However, the credit that may be claimed for a particular taxable year is limited by the total income tax on the U.S. income tax return as well as by the ratio of foreign source net income in each statutory category to total net income. The amount of creditable foreign taxes available for the taxable year that exceeds the limitation (i.e., “excess foreign tax credits”) may be carried back one year and forward ten years. We have $9.1 million of excess foreign tax credits as of March 31, 2018, all of which will expire in fiscal year 2025. As of March 31, 2018, we have $149.0 million of net operating losses in the U.S., of which $2.5 million will expire in fiscal year 2036, $119.7 million will expire in fiscal year 2037 and $26.8 million will expire in fiscal year 2038. In addition, we have net operating losses in certain states totaling $199.7 million which will begin to expire in fiscal year 2022.

We record a valuation allowance when it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of the deferred tax assets depends on the ability to generate sufficient taxable income of the appropriate character in the future and in the appropriate taxing jurisdictions. As of March 31, 2018, valuation allowances were $50.5 million for foreign operating loss carryforwards, $12.3 million for state operating loss carryforwards and $9.1 million for foreign tax credits.

The reconciliation of the U.S. Federal statutory tax rate to the effective income tax rate for the (provision) benefit for income taxes is shown below:

Other, net	1.7	%	(3.1	)%	1.9	%
Effective tax rate	13.5	%	(22.6	)%	2.6	%

In fiscal year 2018, our effective tax rate is 13.5% and includes: (i) tax benefit of $27.0 million related to the impairment of our equity investment in Líder; (ii) tax impact of one-time transition tax on unrepatriated earnings of foreign subsidiaries under the Act of $52.9 million, which is partially offset by the utilization of foreign tax credits of $22.6 million; (iii) tax benefit of $53.0 million as a result of the revaluation of our net deferred tax liabilities; and (iv) tax benefit due to release of $22.8 million of foreign tax credit valuation allowances.

Our effective income tax rate for fiscal year 2017 was (22.6)%representing the income tax expense rate on a pre-tax net loss for the fiscal year, which was reduced by $37.0 million of tax expense for an increase in valuation allowance.

A portion of our aircraft fleet is owned directly or indirectly by our wholly owned Cayman Island subsidiaries. Our foreign operations combined with our leasing structure provided a material benefit to the effective tax rates for fiscal years 2018, 2017 and 2016. In fiscal year 2017, our unfavorable permanent differences, such as valuation allowances and non-tax deductible goodwill write-off had the effect of increasing our income tax expense and reducing our effective tax rate applied to pre-tax losses. Also, our effective tax rates for fiscal years 2018, 2017 and 2016 benefited from the permanent investment outside the U.S. of foreign earnings, upon which no U.S. tax had been provided until the one-time transition tax on unrepatriated earnings of foreign subsidiaries under the Act.

In fiscal year 2017, our effective tax rate was impacted by valuation allowances of $37.0 million and a change in the mix of geographic earnings in which we experienced U.S. losses offset by taxes in jurisdictions taxed on a deemed profit basis. The current effective tax rate was impacted by the tax effect of the $8.7 million goodwill impairment discussed in Note 1.

In August 2008, certain of our existing and newly created subsidiaries completed intercompany leasing transactions involving eleven aircraft. The tax benefit of this transaction is being recognized over the remaining useful life of the assets, which is approximately 13 years. During each of the fiscal years 2017 and 2016, this transaction resulted in a $2.4 million and $2.8 million reduction in our consolidated provision for income taxes, respectively. This transaction resulted in no impact on our consolidated provision for income taxes during fiscal year 2018.

Our operations are subject to the jurisdiction of multiple tax authorities, which impose various types of taxes on us, including income, value added, sales and payroll taxes. Determination of taxes owed in any jurisdiction requires the interpretation of related tax laws, regulations, judicial decisions and administrative interpretations of the local tax authority. As a result, we are subject to tax assessments in such jurisdictions including the re-determination of taxable amounts by tax authorities that may not agree with our interpretations and positions taken. The following table summarizes the years open by jurisdiction as of March 31, 2018:

Jurisdiction	Years Open
U.S.	Fiscal year 2014 to present
U.K.	Fiscal year 2017 to present
Nigeria	Fiscal year 2009 to present
Trinidad	Fiscal year 2005 to present
Australia	Fiscal year 2014 to present
Norway	Fiscal year 2014 to present

The effects of a tax position are recognized in the period in which we determine that it is more-likely-than-not (defined as a more than 50% likelihood) that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. A tax position that meets the more-likely-than-not recognition threshold is measured as the largest amount of tax benefit that is greater than 50% likely of being recognized upon ultimate settlement.

We have analyzed filing positions in the federal, state and foreign jurisdictions where we are required to file income tax returns for all open tax years. We believe that the settlement of any tax contingencies would not have a significant impact on our consolidated financial position, results of operations or liquidity. In fiscal years 2018, 2017 and 2016, we had a net provision of $5.4 million, $0.2 million and $0.4 million, respectively, of reserves for tax contingencies primarily related to non-U.S. income tax on foreign leasing operations. Our policy is to accrue interest and penalties associated with uncertain tax positions in our provision for income taxes. In fiscal years 2018, 2017 and 2016, $0.1 million, $0.2 million and $0.3 million, respectively, in interest and penalties were accrued in connection with uncertain tax positions.

As of March 31, 2018 and 2017, we had $6.7 million and $1.3 million, respectively, of unrecognized tax benefits, all of which would have an impact on our effective tax rate, if recognized.

The activity associated with our unrecognized tax benefit during fiscal years 2018 and 2017 is as follows (in thousands):

	Fiscal Year Ended March 31,
	2018			2017
Unrecognized tax benefits – beginning of fiscal year	$	1,332		$	1,093
Increases for tax positions taken in prior years	7,784			1,059
Decreases for tax positions taken in prior years	(2,434		)	(818		)
Decrease related to statute of limitation expirations	—			(2		)
Unrecognized tax benefits – end of fiscal year	$	6,682		$	1,332

As of March 31, 2018, we have aggregated approximately $517.9 million in unremitted foreign earnings reinvested abroad. Pursuant to the Act, these earnings were subject to the mandatory one-time transition tax and eligible to be repatriated to the U.S. without additional U.S. tax. Although these foreign earnings have been deemed to be repatriated from a U.S. federal income tax perspective, we have not yet completed our assessment of the U.S. tax reform on our plans to reinvest foreign earnings and as such have not changed our prior conclusion that the unremitted earnings are indefinitely reinvested. Accordingly, we have not provided deferred taxes on these unremitted earnings. If our expectations were to change, withholding and other applicable taxes incurred upon repatriation, if any, are not expected to have a significant impact on our results of operations.

We receive a tax benefit that is generated by certain employee stock benefit plan transactions. Under previous accounting guidance, in fiscal years 2017 and 2016, this benefit was recorded directly to additional paid-in-capital on our consolidated balance sheets and did not reduce our effective income tax rate.

Income taxes paid during fiscal years 2018, 2017 and 2016 were $26.7 million, $28.1 million and $28.0 million, respectively.

Note 9 — EMPLOYEE BENEFIT PLANS

Defined Contribution Plans

The Bristow Group Inc. Employee Savings and Retirement Plan (the “Bristow Plan”) covers certain of our U.S. employees. Under the Bristow Plan, we match each participant’s contributions up to 3% of the employee’s compensation. In addition, under the Bristow Plan, we contribute an additional 3% of the employee’s compensation at the end of each calendar year.

Bristow Helicopters and Bristow International Aviation (Guernsey) Limited (“BIAGL”) have a defined contribution plan. This defined contribution plan replaced the defined benefit pension plans described below for future accrual.

On March 1, 2016, the defined benefit pension plan in Norway was closed and replaced with a defined contribution plan.

Our contributions to our defined contribution plans were $22.0 million, $21.8 million and $14.4 million for fiscal years 2018, 2017 and 2016, respectively.

Defined Benefit Plans

The defined benefit pension plans of Bristow Helicopters and BIAGL replaced by the defined contribution plans described above covered all full-time employees of Bristow Aviation and BIAGL employed on or before December 31, 1997. Both plans were closed to future accrual as of February 1, 2004. The defined benefits for employee members were based on the employee’s annualized average last three years’ pensionable salaries up to February 1, 2004, increasing thereafter in line with retail price inflation (prior to 2011) and consumer price inflation (from 2011 onwards), and subject to maximum increases of 5% per year over the period to retirement. Any valuation deficits are funded by contributions by Bristow Helicopters and BIAGL. Plan assets are held in separate funds administered by the plans’ trustee (the “Plan Trustee”), which are primarily invested in equities and debt securities. For members of the two closed defined benefit pension plans, since January 2005, Bristow Helicopters contributes a maximum of 7% of a participant’s non-variable salary, and since April 2006, the maximum employer contribution into the plan has been 7.35% for pilots. Each member is required to contribute a minimum of 5% of non-variable salary for Bristow Helicopters to match the contribution. In addition, there are three defined contribution plans for staff who were not members of the original defined benefit plans, two of which are closed to new members.

⁽¹⁾  Bristow Norway had a final salary defined benefit plan prior to its closing on March 1, 2016, which led to a curtailment and settlement of the projected benefit obligations.

The amount in accumulated other comprehensive loss as of March 31, 2018 expected to be recognized as a component of net periodic pension cost in fiscal year 2019 is $6.5 million, net of tax, and represents amortization of the net actuarial losses.

Discount rate	2.50	%
Rate of compensation increase	3.50	%
Social Security increase amount	3.25	%
Expected return on plan assets	1.50	%
Pension increase rate	—	%

We utilize a British pound sterling denominated AA corporate bond index as a basis for determining the discount rate for our U.K. plans. The expected rate of return assumptions have been determined following consultation with our actuarial advisors. In the case of bond investments, the rates assumed have been directly based on market redemption yields at the measurement date, and those on other asset classes represent forward-looking rates that have typically been based on other independent research by investment specialists.

Under U.K. and Guernsey legislation, it is the Plan Trustee who is responsible for the investment strategy of the plans, although day-to-day management of the assets is delegated to a team of regulated investment fund managers. The Plan Trustee of the Bristow Staff Pension Scheme (the “Scheme”) has the following three stated primary objectives when determining investment strategy:

(i) “funding objective” - to ensure that the Scheme is fully funded using assumptions that contain a modest margin for prudence. Where an actuarial valuation reveals a deficit, a recovery plan will be put in place which will take into account the financial covenant to the employer;

(ii) “stability objective” - to have due regard to the likely level and volatility of required contributions when setting the Scheme’s investment strategy; and

(iii) “security objective” - to ensure that the solvency position of the Scheme (as assessed on a gilt basis) is expected to improve. The Plan Trustee will take into account the strength of the employer’s covenant when determining the expected improvement in the solvency position of the Scheme.

The types of investments are held, and the relative allocation of assets to investments is selected, in light of the liability profile of the Scheme, its cash flow requirements, the funding level and the Plan Trustee’s stated objectives. In addition, in order to avoid an undue concentration of risk, assets are diversified within and across asset classes.

In determining the overall investment strategy for the plans, the Plan Trustee undertakes regular asset and liability modeling (the “ALM”) with the assistance of their U.K. actuary. The ALM looks at a number of different investment scenarios and projects both a range and a best estimate of likely return from each one. Based on these analyses, and following consultation with us, the Trustee determines the benchmark allocation for the plans’ assets.

Incentive Compensation

Incentive and Stock Option Plans — Stock–based awards are currently made under the Bristow Group Inc. 2007 Long-Term Incentive Plan (the “2007 Plan”). As of March 31, 2018, a maximum of 10,646,729 shares of common stock are reserved, including 2,508,134 shares available for incentive awards under the 2007 Plan. 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 our common stock) or performance awards, or any combination thereof, and may be made to outside directors, employees or consultants.

In addition, we have the following incentive and stock plans which have awards outstanding as of March 31, 2018, but under which we no longer make grants:

• The 2004 Stock Incentive Plan (the “2004 Plan”), which provided for awards to officers and key employees in the form of stock options, stock appreciation rights, restricted stock, other stock-based awards or any combination thereof. Options become exercisable at such time or times as determined at the date of grant and expire no more than 10 years after the date of grant.

• The 2003 Non-qualified Stock Option Plan for Non-employee Directors (the “2003 Director Plan”), which provided for a maximum of 250,000 shares of our common stock to be issued pursuant to such plan. As of the date of each annual meeting, each non-employee director who met certain attendance criteria was automatically granted an option to purchase 5,000 shares of our common stock. The exercise price of the options granted was equal to the fair market value of our common stock on the date of grant, and the options were exercisable not earlier than six months after the date of grant and expire no more than ten years after the date of grant.

In June 2017, June 2016 and June 2015, the Compensation Committee of our board of directors authorized the grant of stock options, time vested restricted stock and long-term performance cash awards to participating employees. Each of the stock options has a ten-year term and has an exercise price equal to the fair market value (as defined in the 2007 Plan) of our common stock on the grant date. The options will vest in annual installments of one-third each, beginning on the first anniversary of the grant date. Restricted stock grants vest at the end of three years. Performance cash awards granted in June 2017 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. Performance cash awards granted in June 2015 and June 2016 allow the recipient to receive from 0 to 200% of the target amount at the end of three years depending on how our total shareholder return ranks among a peer group over the performance period. The value of the performance cash awards is calculated on a quarterly basis by comparing the performance of our common stock, including any dividends paid since the award date, against the peer group and has a maximum potential payout of $15.7 million, $7.9 million and $7.4 million for the June 2017, June 2016 and June 2015 awards, respectively. The total value of the awards is recognized as compensation expense over a three-year vesting period with the recognition amount being adjusted quarterly. Compensation expense related to the performance cash awards during fiscal years 2018, 2017 and 2016 was $1.5 million, $7.0 million and $1.4 million, respectively. Performance cash compensation expense has been allocated to our various regions.

Total share-based compensation expense, which includes stock options and restricted stock, was $10.4 million, $12.4 million and $21.2 million for fiscal years 2018, 2017 and 2016, respectively. Stock-based compensation expense is included in general and administrative expense in the consolidated statements of operations and has been allocated to our various regions.

On May 23, 2016, our board of directors approved an amendment and restatement of the 2007 Plan, which was approved by our stockholders on August 3, 2016, that effected each of the following changes: (i) reserved an additional 5,250,000 “shares” (or 2,625,000 full value shares) that, when combined with “shares” remaining available for issuance under the 2007 plan resulted in a total of approximately 6,400,000 “shares” (or approximately 3,200,000 full value shares) available for issuance under the amended and restated 2007 plan, with each option and stock appreciation right granted under the amended and restated 2007 plan counting as one “shares” against such total and with each incentive award that may be settled in common stock counting as two “shares” (or one full value share) against such total; (ii) increased the maximum share-based employee award under the amended and restated 2007 plan from 500,000 full value shares to 1,000,000 full value shares; (iii) set the maximum aggregate compensation and incentive awards that may be provided by the Company in any calendar year to any non-employee member of the board of directors at $1,125,000; and (iv) made other administrative and updating changes.

A summary of our stock option activity for fiscal year 2018 is presented below:

	Weighted Average Exercise Prices		Number of Shares		Weighted Average Remaining Contractual Life	Aggregate Intrinsic Value
						(in thousands)
Outstanding at March 31, 2017	$	42.78	2,843,608
Granted	7.03		1,256,043

Outstanding at March 31, 2018	29.90		3,573,778		6.38	$	7,031
Exercisable at March 31, 2018	46.49		1,812,825		4.00	$	—

Stock options granted to employees under the 2004 and 2007 Plans vest ratably over three years on each anniversary from the date of grant and expire 10 years from the date of grant.

We use a Black-Scholes option pricing model to estimate the fair value of share-based awards. The Black-Scholes option pricing model incorporates various assumptions, including the risk-free interest rate, volatility, dividend yield and the expected term of the options.

The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for a period equal to the expected term of the option. Expected volatilities are based on the historical volatility of shares of our common stock, which has not been adjusted for any expectation of future volatility given uncertainty related to the future performance of our common stock at this time. We also use historical data to estimate the expected term of the options within the option pricing model and groups of employees that have similar historical exercise behavior are considered separately for valuation purposes. The expected term of the options represents the period of time that the options granted are expected to be outstanding. Additionally, we record forfeitures based on actual forfeitures.

The following table shows the assumptions we used to compute the stock-based compensation expense for stock option grants issued during fiscal years 2018, 2017 and 2016.    

	Fiscal Year Ended March 31,
	2018			2017			2016
Risk free interest rate	1.78		%	1.07		%	1.62		%
Expected life (years)	5			5			5
Volatility	56.1		%	46.8		%	28.1		%
Dividend yield	3.98		%	2.74		%	3.14		%
Weighted average grant-date fair value of options granted	$	2.53		$	2.16		$	10.71

Unrecognized stock-based compensation expense related to nonvested stock options was approximately $2.9 million as of March 31, 2018, relating to a total of 1,760,953 unvested stock options. We recognize compensation expense on a straight-line basis over the requisite service period for the entire award. We expect to recognize this stock-based compensation expense over a weighted average period of approximately 1.8 years. The total fair value of options vested during fiscal years 2018, 2017 and 2016 was approximately $4.7 million, $7.8 million and $7.4 million, respectively.

There were no stock options exercised during fiscal years 2018, 2017 and 2016. Therefore, the total intrinsic value, determined as of the date of exercise, total amount of cash we received from option exercises and total tax benefit attributable to options exercised were all zero for fiscal years 2018, 2017 and 2016.

We have restricted stock awards that cliff vest on the third anniversary from the date of grant provided the grantee is still employed by the Company, subject to our retirement policy. Restricted stock granted to non-employee directors under the 2003 Director Plan vest after six months.

We record compensation expense for restricted stock awards based on an estimate of the service period related to the awards, which is tied to the future performance of our stock over certain time periods under the terms of the award agreements. The estimated service period is reassessed quarterly. Changes in this estimate may cause the timing of expense recognized in future periods to accelerate. Compensation expense related to awards of restricted stock for fiscal years 2018, 2017 and 2016 was $6.7 million, $8.0 million and $12.9 million, respectively.

The following is a summary of non-vested restricted stock as of March 31, 2018 and 2017 and changes during fiscal year 2018:    

	Units		Weighted Average Grant Date Fair Value per Unit
Non-vested as of March 31, 2017	739,493		$	26.97
Granted	622,652		7.35
Forfeited	(72,075	)	14.78
Vested	(391,901	)	28.48
Non-vested as of March 31, 2018	898,169		13.69

Unrecognized stock-based compensation expense related to non-vested restricted stock was approximately $6.4 million as of March 31, 2018, relating to a total of 898,169 unvested restricted stock. We expect to recognize this stock-based compensation expense over a weighted average period of approximately 1.6 years.

During June 2017, we awarded certain members of management phantom restricted stock, which will be paid out in cash after three years. Additionally, during March 2018, we awarded 22,034 shares of restricted stock to a consultant, which will be paid out in shares after six months. We account for these awards as liability awards. As of March 31, 2018, we had $0.1 million in other accrued liabilities and $1.0 million in other liabilities and deferred credits on our consolidated balance sheet and recognized $1.1 million in general and administrative expense on our consolidated statement of operations for fiscal year 2018 related to these awards.

The Annual Incentive Compensation Plan provides for an annual award of cash bonuses to key employees based primarily on pre-established objective measures of performance. The bonuses related to this plan were $10.1 million and $5.0 million for fiscal years 2018 and 2017, respectively. There were no bonuses awarded related to this plan during fiscal year 2016.

Additionally, we have a non-qualified deferred compensation plan for our senior executives. Under the terms of the plan, participants can elect to defer a portion of their compensation for distribution at a later date. In addition, we have the discretion to make annual tax deferred contributions to the plan on the participants’ behalf. We contributed $0.1 million, $0.6 million and $1.3 million to this plan in each of fiscal years 2018, 2017 and 2016, respectively. The assets of the plan are held in a rabbi trust and are subject to our general creditors. As of March 31, 2018, the amount held in trust was $2.3 million.

Restrictions on Foreign Ownership of Common Stock — Under the Federal Aviation Act of 1958, as amended (the “Federal Aviation Act”), it is unlawful to operate certain aircraft for hire within the U.S. unless such aircraft are registered with the Federal Aviation Administration (the “FAA”) and the FAA has issued an operating certificate to the operator. As a general rule, aircraft may be registered under the Federal Aviation Act only if the aircraft are owned or controlled by one or more citizens of the U.S. and an operating certificate may be granted only to a citizen of the U.S. For purposes of these requirements, a corporation is deemed to be a citizen of the U.S. only if, among other things, at least 75% of its voting interests are owned or controlled by U.S. citizens. If persons other than U.S. citizens should come to own or control more than 25% of our voting interest or if any other requirements are not met, we have been advised that our aircraft may be subject to deregistration under the Federal Aviation Act, and we may lose our ability to operate within the U.S. Deregistration of our aircraft for any reason, including foreign ownership in excess of permitted levels, would have a material adverse effect on our ability to conduct certain operations within our Americas region. Therefore, our organizational documents currently provide for the automatic suspension of voting rights of shares of our common stock owned or controlled by non-U.S. citizens, and our right to redeem those shares, to the extent necessary to comply with these requirements. As of March 31, 2018, approximately 6,214,000 shares of our common stock were held by persons with foreign addresses. These shares represented approximately 17% of our total outstanding common shares as of March 31, 2018. Our foreign ownership may fluctuate on each trading day because our common stock is publicly traded.

Dividends — In August 2017, we suspended our quarterly dividend as part of a broader plan of reducing costs and improving liquidity. Prior to that, we paid quarterly dividends of $0.07 per share during the first quarter of fiscal year 2018 and each quarter of fiscal year 2017, quarterly dividends of $0.34 per share during the first, second and third quarters of fiscal year 2016 and a dividend of $0.07 per share during the fourth quarter of fiscal year 2016. For fiscal years 2018, 2017 and 2016, we paid dividends totaling $2.5 million, $9.8 million and $38.1 million, respectively, to our stockholders. The declaration of future dividends is at the discretion of our board of directors and subject to our results of operations, financial condition, cash requirements and other factors and restrictions under applicable law and our debt instruments.

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. Diluted earnings per common share excludes options to purchase shares and restricted stock awards, which were outstanding during the period but were anti-dilutive, as follows:

	Fiscal Year Ended March 31,

_____________

⁽¹⁾  Diluted earnings per common share for fiscal year 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 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 earnings per share for fiscal year 2018 as our average stock price during the year did not meet or exceed the conversion requirements.

⁽²⁾  Potentially dilutive shares issuable pursuant to our Warrant Transactions were not included in the computation of diluted income per share for fiscal year 2018, because to do so would have been anti-dilutive. For further details on the Warrant Transactions, see Note 4.

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

Subsequent to the evaluation made in connection with the Original Filing and in connection with the evaluation and procedures carried out in connection with our Quarterly Report on Form 10-Q for the quarterly period 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. As a result of the material weakness in internal control over financial reporting described below, our CEO 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 Annual Report, as a result of commencing Chapter 11 Cases and updating our going concern assessment and the delivery of this 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 cross-acceleration provisions in substantially all of our debt instruments. As a result, we reclassified $1.4 billion as of March 31, 2018 from long-term to short-term on our consolidated balance sheets. For a discussion of changes made to the financial statements that were not related to the material weakness described below, see Note 1 in the “Notes to Consolidated Financial Statements” included elsewhere in this Annual Report.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

Our management is responsible 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 purposes in accordance with GAAP. A company’s internal control over financial reporting includes those policies and procedures that:

• 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. 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 Consolidated Financial Statements” included elsewhere in this Annual Report.

148

The effectiveness of the Company’s internal control over financial reporting as of March 31, 2018 has been audited by KPMG LLP, the independent registered public accounting firm that audited our consolidated financial statements and KPMG LLP 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 herein.

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 CONTROL

Other than the material weakness discussed 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 March 31, 2018, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors

Bristow Group Inc.:

Opinion on Internal Control Over Financial Reporting

We have audited Bristow Group Inc. and subsidiaries’ (the Company) internal control over financial reporting as of March 31, 2018, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, because of the effect of the material weakness, described below, on the achievement of the objectives of the control criteria, the Company has not maintained effective internal control over financial reporting as of March 31, 2018, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of March 31, 2018 and 2017, the related consolidated statements of operations, comprehensive loss, cash flows, and stockholders’ investment and redeemable noncontrolling interests for each of the years in the three-year period ended March 31, 2018, and the related notes (collectively, the consolidated financial statements), and 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, expressed an unqualified opinion on those consolidated financial statements.

In our report dated May 23, 2018, we expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting. As described below, the Company subsequently identified a material weakness in its internal control over financial reporting. Accordingly, management has revised its assessment about the effectiveness of the Company’s internal control over financial reporting, and our present opinion on the effectiveness of the Company’s internal control over financial reporting, as of March 31, 2018, as presented herein, is different from that expressed in our previous report.

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. A material weakness related to not appropriately considering the requirements under certain of the Company’s secured financing and lease agreements and its obligation to monitor compliance with the underlying non-financial covenants, has been identified and included in management’s assessment. The material weakness was considered in determining the nature, timing, and extent of audit tests applied in our audit of the 2018 consolidated financial statements, and this report does not affect our report on those consolidated financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A 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 purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) 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 that the degree of compliance with the policies or procedures may deteriorate.

OPERATIONS, BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Operations

Bristow Group Inc., a Delaware corporation (together with its consolidated entities, unless the context requires otherwise, “Bristow Group”, the “Company”, “we”, “us”, or “our”), is the leading provider of industrial aviation services to the worldwide offshore energy industry based on the number of aircraft operated. With a fleet of 405 aircraft as of March 31, 2018, including 110 held by unconsolidated affiliates, we and our affiliates conduct 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 and our affiliates also provide private sector search and rescue (“SAR”) services in Australia, Canada, Norway, Russia, Trinidad and the United States, and public sector SAR services in the U.K. on behalf of the Maritime & Coastguard Agency. Certain of our affiliates also provide regional fixed wing scheduled and charter services in the U.K., Nigeria and Australia.

Bankruptcy, Restructuring Support Agreement and Going Concern

The Company’s liquidity outlook has changed since the date of the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2018, originally filed with the U.S. Securities and Exchange Commission (“SEC”) on May 23, 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 (the Original Filing, as amended by this Amendment No. 1, this Amended 10-K”), 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 this Amended 10-K 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 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 this Amended 10-K on our consolidated balance sheet.

As discussed in the Explanatory Note in this Annual Report, 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”) 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.

As previously disclosed in the Company’s Current Report on Form 8-K filed with the SEC on May 13, 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 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 consolidated financial statements do not include any adjustments that might result from the outcome of 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 consolidated statements of changes in stockholders’ investment and redeemable noncontrolling interest reflect immaterial adjustments to the historical balances in retained earnings and accrued wages, benefits and related taxes for the years ended March 31, 2016, 2017 and 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 for March 31, 2015, 2016, 2017 and 2018 of $4.9 million. Retained earnings as reported was $1,284,442,000 and $1,172,273,000 for March 31, 2015 and 2016, respectively, compared to as adjusted of $1,279,493,000 and $1,167,324,000 for March 31, 2015 and 2016, respectively, after the correction. In addition, below are amounts as reported and as adjusted for each year presented (in thousands):

	March 31, 2018				March 31, 2017
	As reported	Adjustments		As adjusted	As reported	Adjustments		As adjusted
Accrued wages, benefits and related taxes	62,385	4,949		67,334	59,077	4,949		64,026
Retained earnings	793,783	(4,949	)	788,834	991,906	(4,949	)	986,957
Total Bristow Group stockholders’ investment	1,175,840	(4,949	)	1,170,891	1,289,207	(4,949	)	1,284,258
Total stockholders’ investment	1,183,093	(4,949	)	1,178,144	1,294,232	(4,949	)	1,289,283

The income statement and cash flow impact of this accrual for the fiscal years ended March 31, 2016, 2017 and 2018 were not corrected as they were considered to be inconsequential to the Company’s prior period interim and annual consolidated financial statements.

Basis of Presentation

The consolidated financial statements include the accounts of Bristow Group Inc. and its consolidated entities after elimination of all significant intercompany accounts and transactions. Investments in affiliates in which we have a majority voting interest and entities that meet the criteria of Variable Interest Entities (“VIEs”) of which we are the primary beneficiary are consolidated. See discussion of VIEs in Note 2. We apply the equity method of accounting for investments in entities if we have the ability to exercise significant influence over an entity that (a) does not meet the variable interest entity criteria or (b) meets the variable interest entity criteria, but for which we are not deemed to be the primary beneficiary. We apply the cost method of accounting for investments in other entities if we do not have the ability to exercise significant influence over the unconsolidated affiliate. These investments in private companies are carried at cost and are adjusted only for capital distributions and other-than-temporary declines in value. Dividends from cost method investments are recognized in earnings from unconsolidated affiliates, net of losses, when paid.

Our fiscal year ends March 31, and we refer to fiscal years based on the end of such period. Therefore, the fiscal year ended March 31, 2018 is referred to as fiscal year 2018.

Certain reclassifications of prior period information have been made to conform to the presentation of the current period information as a result of an adoption of a required accounting standard. In prior period financial statements, we had included employee taxes paid for withheld shares as a cash flow operating activity. During fiscal year 2018, we have reclassified employee taxes paid for withheld shares to be presented as a cash flow financing activity as a result of the adoption of new accounting standards effective April 1, 2017. These reclassifications had no effect on our consolidated statements of operations or our consolidated balance sheet as previously reported.

Summary of Significant Accounting Policies

Use of Estimates — The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expense during the reporting period. Actual results could differ from those estimates. Areas where accounting estimates are made by management include:

• Allowances for doubtful accounts;

• Inventory allowances;

• Property and equipment;

• Goodwill, intangible and other long-lived assets;

• Pension benefits;

• Contingent liabilities; and

• Taxes.

Cash and Cash Equivalents — Our cash equivalents include funds invested in highly-liquid debt instruments with original maturities of 90 days or less.

Accounts Receivable — Trade and other receivables are stated at net realizable value. We grant short-term credit to our clients, primarily major integrated, national and independent oil and gas companies. We establish allowances for doubtful accounts on a case-by-case basis when a determination is made that the required payment is unlikely to occur. In establishing these allowances, we consider a number of factors, including our historical experience, change in our clients’ financial position and restrictions placed on the conversion of local currency into U.S. dollars, as well as disputes with clients regarding the application of contract provisions to our services. Also included in accounts receivable as of March 31, 2018 is $19.8 million for cash collateralization of letters of credit.

The following table is a rollforward of the allowance for doubtful accounts from non-affiliates (in thousands):

During fiscal year 2016, the allowance for doubtful accounts for non-affiliates was increased primarily for amounts due from two clients in Nigeria and one client in Australia for which we no longer believed collection was probable.

As of March 31, 2018 and 2017, there were no allowances for doubtful accounts related to accounts receivable due from affiliates.

Inventories — Inventories are stated at the lower of average cost or net realizable value and consist primarily of spare parts. The following table is a rollforward of the allowance related to dormant, obsolete and excess inventory (in thousands):

	Fiscal Year Ended March 31,
	2018			2017			2016
Balance – beginning of fiscal year	$	21,514		$	27,763		$	45,414

Foreign currency effects	1,514			(803		)	(854		)
Balance – end of fiscal year	$	26,030		$	21,514		$	27,763

During fiscal years 2018, 2017 and 2016, we increased our inventory allowance by $6.4 million, $1.6 million and $0.2 million, respectively, as a result of our periodic assessment of inventory that was dormant or obsolete within our operational fleet of aircraft. For discussion of impairment of inventories, see Loss on Impairment below. The impairment of inventories is included in loss on impairment and additional allowances are included in direct costs on our consolidated statements of operations.

Prepaid Expenses and Other Current Assets — As of March 31, 2018 and 2017, prepaid expenses and other current assets included the short-term portion of contract acquisition and pre-operating costs totaling $10.8 million and $9.7 million, respectively, related to SAR contracts in the U.K. and two client contracts in Norway. These contract acquisition and pre-operating costs are recoverable under the contracts and are being expensed over the terms of the contracts. During fiscal years 2018 and 2017, we expensed $11.4 million and $16.9 million, respectively, due to the start-up of these contracts and the cancellation of a contract in Australia.

Property and Equipment — Property and equipment are stated at cost. Property and equipment includes construction in progress, primarily consisting of progress payments on aircraft purchases and facility construction, of $67.7 million and $199.3 million as of March 31, 2018 and 2017, respectively. Interest costs applicable to the construction of qualifying assets are capitalized as a component of the cost of such assets.

Depreciation and amortization are provided using the straight-line method over the estimated useful lives of the assets. The estimated useful lives of aircraft generally range from 5 to 15 years, and the residual value used in calculating depreciation of aircraft generally ranges from 30% to 50% of cost. The estimated useful lives for buildings on owned properties range from 15 to 30 years. Other depreciable assets are depreciated over estimated useful lives ranging from 3 to 15 years, except for leasehold improvements which are depreciated over the lesser of the useful life of the improvement or the lease term (including any period where we have options to renew if it is probable that we will renew the lease). The cost and related accumulated depreciation of assets sold or otherwise disposed of are removed from the accounts and the resulting gains or losses are included in gain (loss) on disposal of assets.

We capitalize betterments and improvements to our aircraft and depreciate such costs over the remaining useful lives of the aircraft. Betterments and improvements increase the life or utility of an aircraft.

For further details on property and equipment, see Note 3.

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 $19.9 million and $19.8 million as of March 31, 2018 and 2017, respectively, related to our reporting units were as follows (in thousands):

The Bristow Norway and Eastern Airways International Limited (“Eastern Airways”) acquisitions, completed in October 2008 and February 2014, respectively, included in our Europe Caspian region, resulted in intangible assets for client contracts, client relationships, trade names and trademarks, internally developed software and licenses. The Capiteq Limited, operating under the name Airnorth, acquisition completed in January 2015, included in our Asia Pacific region, resulted in intangible assets for client contracts, client relationships and trade name and trademarks. For discussion of impairment of long-lived assets, including purchased intangibles subject to amortization, see Loss on Impairment below.

Other Assets — In addition to the intangible assets discussed above, other assets primarily include deferred tax assets of $42.6 million and $34.8 million as of March 31, 2018 and 2017, respectively, and the long-term portion of contract acquisition and pre-operating costs totaling $50.6 million and $51.1 million as of March 31, 2018 and 2017, respectively, related to SAR contracts in the U.K. and two client contracts in Norway, which are recoverable under the contracts and are being expensed over the life of the contracts.

Contingent Liabilities — We establish reserves for estimated loss contingencies when we believe a loss is probable and the amount of the loss can be reasonably estimated. Our contingent liability reserves relate primarily to potential tax assessments, litigation, personal injury claims and environmental liabilities. Results for each reporting period include revisions to contingent liability reserves resulting from different facts or information which becomes known or circumstances which change and affect our previous assumptions with respect to the likelihood or amount of loss. Such revisions are based on information which becomes known or circumstances that change after the reporting date for the previous period through the reporting date of the current period. Reserves for contingent liabilities are based upon our assumptions and estimates regarding the probable outcome of the matter. Should the outcome differ from our assumptions and estimates or other events result in a material adjustment to the accrued estimated reserves, revisions to the estimated reserves for contingent liabilities would be required to be recognized. Legal costs are expensed as incurred.

Proceeds from casualty insurance settlements in excess of the carrying value of damaged assets are recognized in gain (loss) on disposal of assets when we have received proof of loss documentation or are otherwise assured of collection of these amounts.

Some of our acquisitions include a provision that provides for additional consideration to be paid to the sellers of the acquired company based on the achievement of specified performance thresholds.  In such cases, we record the obligations to pay those amounts at fair value at the acquisition date and include such obligations in the consideration transferred. We assess the estimated fair value of the contractual obligation to pay the contingent consideration on a quarterly basis and any changes in estimated fair value are recorded as accretion expense included in depreciation and amortization on our consolidated statements of operations. In other cases, additional consideration is based on the achievement of performance thresholds and continued employment with the Company. In these cases, we record such amounts in general and administrative expense when such additional consideration is earned.

Loss on Impairment

Loss on impairment includes the following (in thousands):

	Fiscal Year Ended March 31,
	2018		2017		2016
Impairment of inventories	$	5,717	$	7,572	$	5,439
Impairment of investment in unconsolidated affiliates	85,683		—		—
Impairment of goodwill	—		8,706		41,579
Impairment of other long-lived assets	—		—		8,086
	$	91,400	$	16,278	$	55,104

For details on our analysis of impairment of inventories, investment in unconsolidated affiliates, goodwill and other long-lived assets, see discussion below.

Inventories— During fiscal years 2018, 2017 and 2016, we recorded impairment charges of $5.7 million, $7.6 million and $5.4 million, respectively, to write-down certain spare parts within inventories to market value. The impairment charges in fiscal year 2018 were recorded to impair inventory used in our training fleet at Bristow Academy, Inc. (“Bristow Academy”) ($1.2 million) and our fixed wing operations at Eastern Airways ($4.5 million) as a result of changes in expected future utilization of aircraft within those operations. These charges were recorded as a direct reduction in the value of spare parts inventories to record them at net realizable value. The impairment charges in fiscal year 2017 were recorded primarily due to a change in estimate of consumption of inventory and the continued decline in the secondary market for inventory resulting from our decision to cease operation of certain older model aircraft within our fleet in fiscal year 2017. The impairment charges in fiscal year 2016 related primarily to spare parts held for a large aircraft model where we decided to accelerate removal from our fleet by the end of fiscal year 2016. As we had intended to operate these model types longer in certain markets, we identified excess inventory that would not be used on our aircraft and therefore needed to be sold or otherwise disposed of. The charges recorded in fiscal years 2017 and 2016 were recorded as additional allowances required against spare parts supporting the specific aircraft model types.

Investment in Unconsolidated Affiliates — We perform regular reviews of each investee’s financial condition, the business outlook for its products and services, and its present and projected results and cash flows. When an investee has experienced consistent declines in financial performance or difficulties raising capital to continue operations, and when we expect the decline to be other-than-temporary, the investment is written down to fair value. Actual results may vary from estimates due to the uncertainty regarding the projected financial performance of investees, the severity and expected duration of declines in value, and the available liquidity in the capital markets to support the continuing operations of the investees in which we have investments. In fiscal year 2018, we recorded an $85.7 million impairment to our investment in Líder Táxi Aéreo S.A. (“Líder”) in our Americas region. For further details, see below. We did not recognize any impairment charges related to our investments in unconsolidated affiliates in fiscal years 2017 and 2016.

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. Líder’s management has significantly decreased their future financial projections as a result of recent tender awards announced by their largest client, Petrobras. This significant decline in future forecasted results, coupled with previous declining financial results, triggered our review of the investment for potential other-than-temporary impairment as of March 31, 2018.

We estimated the fair value of our investment in Líder using a variety of valuation methods, including the income and market approaches. The determination of estimated fair value required us to use significant unobservable inputs, representative of a Level 3 fair value measurement, including assumptions related to the future performance of the investment, such as projected demand for services and rates.

The income approach was based on a discounted cash flow model, which utilized present values of cash flows to estimate fair value. The future cash flows were projected based on estimates of future rates for services, utilization, operating costs, capital requirements, growth rates and terminal values. Forecasted rates and utilization take into account current market conditions and our anticipated business outlook, both of which have been impacted by the adverse changes in the offshore energy business environment from the current downturn. Operating costs were forecasted using a combination of historical average operating costs and expected future costs, including ongoing cost reduction initiatives. Capital requirements in the discounted cash flow model were based on management’s estimates of future capital costs resulting from expected market demand in future periods. The estimated capital requirements included cash outflows for new aircraft, infrastructure and improvements. A terminal period was used to reflect our estimate of stable, perpetual growth. The future cash flows were discounted using a market-participant risk-adjusted weighted average cost of capital (“WACC”). These assumptions were derived from unobservable inputs and reflect management’s judgments and assumptions.

The market approach was based upon the application of price-to-earnings multiples to management’s estimates of future earnings. Management’s earnings estimates were derived from unobservable inputs that require significant estimates, judgments and assumptions as described in the income approach.

For purposes of the Líder impairment test, we calculated the estimated fair value as the weighted average of the values calculated under the income approach and the market approach.

Goodwill— As discussed above, we test goodwill for impairment on an annual basis or when events or changes in circumstances indicate that a potential impairment exists. For the purposes of performing an analysis of goodwill, we evaluate whether there are reporting units below the reporting segment we disclose for segment reporting purposes by assessing whether our regional management typically reviews results and whether discrete financial information exists at a lower level.

During the three months ended September 30, 2015, we noted rapid and significant declines in the market value of our common stock and an overall reduction in expected operating results resulting from the downturn in the oil and gas industry due to reduced crude oil prices. The impact on our results was reflected in an increase in the number of idle aircraft and reduction in forecasted results across our global oil and gas helicopter operations, and was reflected in reduced operating revenue for our business for the three months ended September 30, 2015, when excluding growth from the U.K. SAR contract and the addition of Airnorth. Based on these factors, we concluded that the fair value of our goodwill could have fallen below its carrying value and that an interim period analysis of goodwill was required.

We performed our analysis of goodwill for the following reporting units as of September 30, 2015, with goodwill as reflected below prior to any impairment recorded:    

•Bristow Norway, within our Europe Caspian region, which included $12.1 million of goodwill;

•Eastern Airways, within our Europe Caspian region, which included $24.6 million of goodwill;

•Airnorth, within our Asia Pacific region, which included $21.9 million of goodwill;

•Our Africa region, which included $5.9 million of goodwill; and

•Bristow Academy, within Corporate and other, which included $10.2 million of goodwill.

We performed the interim impairment test of goodwill across the reporting units discussed above, noting that the estimated fair values of Eastern Airways, Airnorth and our Africa region exceeded the carrying values. The estimated fair values of Bristow Norway and Bristow Academy were below their carrying values, resulting in an impairment of all of the goodwill for those reporting units of $22.3 million reflected in loss on impairment in our statement of operations during fiscal year 2016. We updated the impairment analysis as of March 31, 2016 for the Eastern Airways, Airnorth and our Africa region. The estimated fair value of Airnorth exceeded the carrying value. The estimated fair value of Eastern Airways and our Africa region was below the carrying value, resulting in an impairment of a portion of the goodwill for Eastern Airways of $13.1 million and all of the goodwill for Africa of $6.2 million reflected in our loss on impairment in our statement of operations during fiscal year 2016.

During the three months ended December 31, 2016, we noted an overall reduction in expected operating results for Eastern Airways from the continued downturn in the oil and gas market and performed an interim impairment test of goodwill for Eastern Airways. Based on this factor, we concluded that the fair value of our goodwill could have fallen below its carrying value and that an interim period analysis of goodwill was required.

We performed the interim impairment test of goodwill for Eastern Airways as of December 31, 2016, noting that the estimated fair value of Eastern Airways was below its carrying value, resulting in an impairment of all of the remaining goodwill related to Eastern Airways and a loss of $8.7 million reflected in loss on impairment in our statement of operations for fiscal year 2017.

The only remaining goodwill recorded as of March 31, 2018 relates to Airnorth within our Asia Pacific region. We did not have any triggering events to test Airnorth for impairment during fiscal years 2018 or 2017.

We estimated the implied fair value of the reporting units using a variety of valuation methods, including the income and market approaches. The determination of estimated fair value required us to use significant unobservable inputs, representative of a Level 3 fair value measurement, including assumptions related to the future performance of the reporting units, such as projected demand for our services and rates.

The income approach was based on a discounted cash flow model, which utilized present values of cash flows to estimate fair value. The future cash flows were projected based on our estimates of future rates for our services, utilization, operating costs, capital requirements, growth rates and terminal values. Forecasted rates and utilization take into account current market conditions and our anticipated business outlook, both of which have been impacted by the adverse changes in the offshore energy business environment from the current downturn. Operating costs were forecasted using a combination of our historical average operating costs and expected future costs, including ongoing cost reduction initiatives. Capital requirements in the discounted cash flow model were based on management’s estimates of future capital costs resulting from expected market demand in future periods. The estimated capital requirements included cash outflows for new aircraft, infrastructure and improvements. A terminal period was used to reflect our estimate of stable, perpetual growth. The future cash flows were discounted using a market-participant risk-adjusted WACC for each of the reporting units individually and in the aggregate. These assumptions were derived from unobservable inputs and reflect management’s judgments and assumptions.

The market approach was based upon the application of price-to-earnings multiples to management’s estimates of future earnings adjusted for a control premium. Management’s earnings estimates were derived from unobservable inputs that require significant estimates, judgments and assumptions as described in the income approach.

For purposes of the goodwill impairment test, we calculated the reporting units’ estimated fair value as the average of the values calculated under the income approach and the market approach.

During fiscal year 2016, we evaluated the estimated fair value of our reporting units compared to our market capitalization. The aggregate fair values of our reporting units exceeded our market capitalization, and we believe the resulting implied control premium was reasonable based on recent market transactions within our industry or other relevant benchmark data. During fiscal years 2018 and 2017, this calculation was not performed because the reporting unit with goodwill did not represent a significant portion of our business.

The estimates used to determine the fair value of the reporting units discussed above reflect management’s best estimates, and we believe they are reasonable. Future declines in the reporting units’ operating performance or our anticipated business outlook may reduce the estimated fair value of these reporting units and result in additional impairments. Factors that could have a negative impact on the fair value include, but are not limited to:

• decreases in estimated rates and utilization due to greater-than-expected market pressures, downtime and other risks associated with offshore energy operations;

•sustained declines in our common stock price;

•decreases in revenue due to our inability to attract and retain skilled personnel;

• changes in worldwide offshore energy transportation supply and demand, competition or technology;

• changes in future levels of drilling activity and expenditures, whether as a result of global capital markets and liquidity, prices of oil and natural gas or otherwise, which may cause our clients to further reduce offshore production and drilling activities;

• possible cancellation or suspension of contracts as a result of mechanical difficulties, performance or other reasons;

• inability to manage costs during the current downturn and in future periods;

• increases in the market-participant risk-adjusted WACC; and

•declines in anticipated growth rates.

Adverse changes in one or more of these factors could result in additional goodwill impairment in future periods.

Other Long-lived Assets — Long-lived assets, such as property and equipment, and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If the carrying amount of an asset group to be held and used exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset group exceeds the fair value of the asset group. See discussion of impairment of assets held for sale and property and equipment in Note 3. During fiscal year 2016, we recorded an impairment of our Eastern Airways purchased intangibles in our Europe Caspian region of $8.1 million related to our client relationships. In fiscal year 2016, we noted an overall reduction in expected operating results for Eastern Airways from the continued downturn in the oil and gas market and performed impairment tests of intangibles for Eastern Airways. The fair value of Eastern Airways intangibles was estimated using the income approach. The income approach indicates value for a subject asset based on the present value of cash flows projected to be generated by the asset. Projected cash flows are discounted at a required market rate of return that reflects the relative risk of achieving the cash flows and the time value of money.

Other Accrued Liabilities — Other accrued liabilities of $66.0 million and $46.7 million as of March 31, 2018 and 2017, respectively, includes the following (in thousands):

_______________

⁽¹⁾  See Note 3 for further details on deferred original equipment manufacturer (“OEM”) cost recovery.

Deferred Sale Leaseback Advance — During fiscal year 2014, we received payment of approximately $106.1 million for progress payments we had made on seven aircraft under construction, and we assigned any future payments due on these construction agreements to the purchaser. As we had the obligation and intent to lease the aircraft back from the purchaser upon completion, we recorded a liability equal to the cash received and additional payments made by the purchaser totaling $147.4 million, with a corresponding increase to construction in progress. During fiscal year 2015, we took delivery and entered into leases for five of the aircraft and removed a total of $183.7 million and $182.6 million from construction in progress and deferred sale leaseback advance, respectively, on our consolidated balance sheet. During fiscal year 2016, we took delivery and entered into leases for the remaining two aircraft and removed a total of $75.8 million and $74.3 million from construction in progress and deferred sale leaseback advance, respectively, on our consolidated balance sheet. As of March 31, 2016, the construction in progress and deferred sale leaseback advance liability related to these deferred sale leaseback transactions were removed from our consolidated balance sheet.

Revenue Recognition — In general, we recognize revenue when it is both realized or realizable and earned. We consider revenue to be realized or realizable and earned when the following conditions exist: there is persuasive evidence of an arrangement (generally a client contract exists); the services or products have been performed or delivered to the client; the sales price is fixed or determinable; and collection has occurred or is probable.

Revenue from helicopter services, including SAR services, is recognized based on contractual rates as the related services are performed. The charges under these contracts are generally based on a two-tier rate structure consisting of a daily or monthly fixed fee plus additional fees for each hour flown. These contracts are for varying periods and generally permit the client to cancel the contract before the end of the term. We also provide services to clients on an “ad hoc” basis, which usually entails a shorter contract notice period and duration. The charges for ad hoc services are based on an hourly rate or a daily or monthly fixed fee plus additional fees for each hour flown. 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 rate increases when the criteria outlined above have been met. This generally includes written recognition from the clients that they are in agreement with the amount of the rate escalation. Cost reimbursements from clients are recorded as reimbursable revenue with the related reimbursed costs recorded as reimbursable expense on our consolidated statements of operations.

Eastern Airways and Airnorth primarily earn revenue through charter and scheduled airline services and provision of airport services (Eastern Airways only). Both chartered and scheduled airline service revenue is recognized net of passenger taxes and discounts. Revenue is recognized 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. Airport services revenue is recognized when earned.

Prior to the sale on November 1, 2017, Bristow Academy, our helicopter training unit, primarily earned revenue from military training, flight training provided to individual students and ground school courses. We recognized revenue from these sources using the same revenue recognition principles described above as services were provided. We consider revenue to be realized or realizable and earned when the following conditions exist: there is persuasive evidence of an arrangement (generally a contract exists); the services have been performed or delivered to the client or student; the sales price is fixed and determinable; and collection has occurred or is probable.

Pension Benefits — See Note 9 for a discussion of our accounting for pension benefits.

Maintenance and Repairs — We generally charge maintenance and repair costs, including major aircraft component overhaul costs, to earnings as the costs are incurred. However, certain major aircraft components, such as engines and transmissions, are maintained by third-party vendors under contractual agreements also referred to as power-by-the hour maintenance agreements. Under these agreements, we are charged an agreed amount per hour of flying time related to maintenance, repair and overhaul of the parts and components covered. The costs charged under these contractual agreements are recognized in the period in which the flight hours occur. To the extent that we have not yet been billed for costs incurred under these arrangements, these costs are included in accrued maintenance and repairs on our consolidated balance sheets. From time to time, we receive credits from our original equipment manufacturers as settlement for additional labor and maintenance expense costs incurred for aircraft performance issues. We record these credits as a reduction in maintenance expense when the credits are utilized in lieu of cash payments for purchases or services. The cost of certain major overhauls on owned fixed-wing aircraft operated by Eastern Airways and Airnorth are capitalized when incurred and depreciated over the period until the next expected major overhaul. The cost of major overhauls on leased fixed-wing aircraft operated by Eastern Airways and Airnorth are charged to maintenance and repair costs when incurred.

Taxes — We follow the liability method of accounting for income taxes. Under this method, deferred income tax assets and liabilities are determined based upon temporary differences between the carrying amount and tax basis of our assets and liabilities and measured using enacted tax rates and laws that will be in effect when the differences are expected to reverse. The effect on deferred income tax assets and liabilities of a change in the tax rates is recognized in income in the period in which the change occurs. We record a valuation reserve when we believe that it is more likely than not that any deferred income tax asset created will not be realized.

In assessing the realizability of deferred income tax assets, management considers whether it is more-likely-than-not that some portion or all of the deferred income tax assets will not be realized. The ultimate realization of deferred income tax assets is dependent upon the generation of future taxable income during the periods in which such temporary differences become deductible.

We recognize tax benefits attributable to uncertain tax positions when it is more-likely-than-not that a tax position will be sustained upon examination by the authorities. The benefit from a position that has surpassed the more-likely-than-not threshold is the largest amount of benefit that is more than 50% likely to be realized upon settlement. We recognize interest and penalties accrued related to unrecognized tax benefits as a component of benefit (provision) for income taxes in our statement of operations.

Foreign Currency — In preparing our financial statements, we must convert all non-U.S. dollar currencies to U.S. dollars. Balance sheet information is presented based on the exchange rate as of the balance sheet date, and statement of operations information is presented based on the average exchange rate for the period. The various components of stockholders’ investment are presented at their historical average exchange rates. The resulting difference after applying the different exchange rates is the currency translation adjustment, which is reported in stockholders’ investment as accumulated other comprehensive gains or losses. Foreign currency transaction gains and losses are recorded in other income (expense), net in our statement of operations and result from the effect of changes in exchange rates on transactions denominated in currencies other than a company’s functional currency, including transactions between consolidated companies. An exception is made where an intercompany loan or advance is deemed to be of a long-term investment nature, in which instance foreign currency transaction gains or losses are included as currency translation adjustments and are reported in stockholders’ investment as accumulated other comprehensive gains or losses. Changes in exchange rates could cause significant changes in our financial position and results of operations in the future.

As a result of changes in exchange rates, we recorded foreign currency transaction losses of approximately $2.6 million, $2.9 million and $4.3 million during fiscal years 2018, 2017 and 2016, respectively. Our earnings from unconsolidated affiliates, net of losses, are also affected by the impact of changes in foreign currency exchange rates on the reported results of our unconsolidated affiliates. During fiscal years 2018, 2017 and 2016, earnings from unconsolidated affiliates, net of losses, decreased by $2.0 million, $3.2 million and $22.4 million, respectively, as a result of the impact of changes in foreign currency exchange rates on the earnings of our unconsolidated affiliates, primarily the impact of changes in the Brazilian real to U.S. dollar exchange rate on earnings for our affiliate in Brazil. See further discussion of foreign exchange risks and controls under Item 7A. “Quantitative and Qualitative Disclosures about Market Risk” included elsewhere in this Annual Report.

Incentive Compensation — See Note 9 for a discussion of our accounting for incentive compensation arrangements.

Interest Income (Expense), Net — During fiscal years 2018, 2017 and 2016, interest expense, net consisted of the following (in thousands):

	Fiscal Year Ended March 31,
	2018			2017			2016
Interest income	$	677		$	943		$	1,058
Interest expense	(77,737		)	(50,862		)	(35,186		)
Interest expense, net	$	(77,060	)	$	(49,919	)	$	(34,128	)

Other Income (Expense), Net — The amounts for fiscal years 2018, 2017 and 2016 primarily include the foreign currency transaction gains and losses described under “Foreign Currency” above.

Accretion of Redeemable Noncontrolling Interest — Accretion of redeemable noncontrolling interest of $1.5 million for fiscal year 2016 related to put arrangements whereby the noncontrolling interest holders could require us to redeem the remaining shares of Airnorth (prior to repurchasing the remaining 15% of the outstanding shares in November 2015 discussed in Note 2) and Eastern Airways (prior to repurchasing the remaining 40% of the outstanding shares in January 2018 discussed Note 2) at a formula-based amount that is not considered fair value (the “redemption amount”). No accretion of redeemable noncontrolling interest was recorded in fiscal years 2018 or 2017. Redeemable noncontrolling interest was adjusted each period for comprehensive income, dividends attributable to the noncontrolling interest and changes in ownership interest, if any, such that the noncontrolling interest represented the proportionate share of Airnorth’s and Eastern Airways’ equity (the “carrying value”). Additionally, at each period end we were required to compare the redemption amount to the carrying value of the redeemable noncontrolling interest and record the redeemable noncontrolling interest at the higher of the two amounts, with a corresponding charge or credit directly to retained earnings. While this charge or credit did not impact net income (loss), it did result in a reduction or increase of income (loss) available to common shareholders in the calculation of earnings (loss) per share. In November 2015, we purchased the remaining 15% of the outstanding shares of Airnorth for A$7.3 million ($5.3 million) resulting in a reduction of $5.5 million to redeemable noncontrolling interest and an increase of $2.6 million to additional paid-in capital on our consolidated balance sheet. In January 2018, we acquired the remaining 40% of the outstanding shares of Eastern Airways for nominal consideration, resulting in a reduction of $6.1 million to redeemable noncontrolling interest and a corresponding increase to additional paid-in capital on our consolidated balance sheet.

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 for revenue from contracts with customers. The core principle of the new standard is to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration the entity expects to be entitled to in exchange for those goods or services through a five-step model. The new standard also requires enhanced disclosures regarding the nature, amount, timing, and uncertainty of revenue and the related cash flows arising from contracts with customers. This new standard is effective for the Company beginning on April 1, 2018. The standard is required to be adopted using either the full retrospective approach, with all prior periods presented adjusted, or the modified retrospective approach, with a cumulative adjustment to retained earnings on the balance sheet. We adopted this standard on April 1, 2018, utilizing the modified retrospective method. Under the modified retrospective method of adoption, prior year reported results are not recast; however, a cumulative-effect adjustment to retained earnings at April 1, 2018 is recorded, if applicable. In addition, quarterly disclosures will include comparative information for fiscal year 2018 financial statement line items under current guidance. To the extent applicable, upon adoption, we may be required to comply with expanded disclosure requirements, including the disaggregation of revenues to depict the nature and uncertainty of types of revenues, contract assets and liabilities, performance obligations, significant judgments and estimates affecting the amount and timing of revenue recognition, and determination of transaction prices. The adoption of this guidance did not result in a cumulative-effect adjustment on April 1, 2018.

In November 2015, the FASB issued accounting guidance that changed how deferred taxes are classified on an entity’s balance sheet. The accounting guidance requires that all deferred tax assets and liabilities, along with any related valuation allowance, be classified as noncurrent on the balance sheet. The new guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016 and early adoption is permitted. The guidance may be applied either prospectively, for all deferred tax assets and liabilities, or retrospectively. If applied prospectively, entities are required to include a statement that prior periods were not retrospectively adjusted. If applied retrospectively, entities are also required to include quantitative information about the effects of the change on prior periods. We adopted this accounting guidance using the prospective adjustment option effective April 1, 2017 and prior periods were not retrospectively adjusted. As of March 31, 2017, we had $0.1 million in current deferred taxes and $0.8 million in current deferred liabilities that were reclassified to noncurrent upon adoption of this accounting guidance.

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. We have not yet adopted this standard and are currently evaluating the effect this standard will have on our financial statements.

In March 2016, the FASB issued accounting guidance related to accounting for employee share-based payments. The accounting guidance is intended to simplify several aspects of accounting for share-based payment award transactions including income tax consequences, classification of awards as either equity or liabilities and classification on the statements of cash flows. This accounting guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016 and early adoption is permitted. We adopted this standard effective April 1, 2017. The requirements related to the tax consequences of share-based payments were applied prospectively and resulted in $1.8 million recorded as an increase to the income tax provision during fiscal year 2018. We elected to record forfeitures of share-based awards based on actual forfeitures, which did not have a material effect on our financial statements. The provisions related to the presentation of excess tax benefits on the statements of cash flows did not impact our financial statements as there was no excess tax benefit recorded for the periods presented. The provisions related to presenting employee taxes paid for withheld shares as a cash flow financing activity required us to revise our prior period consolidated statement of cash flows by $0.8 million and $2.2 million with a decrease in net cash used in operating activities and a corresponding decrease in net cash provided by financing activities for fiscal years 2017 and 2016, respectively. None of the other provisions of the pronouncement had a material effect 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 assets 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 have not yet adopted this accounting guidance and are currently evaluating the effect this accounting guidance will have on our financial statements.

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 have not yet adopted this accounting guidance.

In March 2017, the FASB issued accounting guidance related to the presentation of net periodic pension cost and net periodic postretirement 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 postretirement 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 postretirement benefit in assets. We have not yet adopted this accounting guidance and are currently evaluating the effect this accounting guidance will have on our financial statements.

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 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 not yet adopted this accounting guidance and are currently evaluating the effect this accounting guidance will have on our financial statements.

In August 2017, the FASB issued new accounting guidance on derivatives and hedging, which amends and simplifies existing guidance in order to allow companies to more accurately present the economic effects of risk management activities in the financial statements. The two primary benefits resulting from these changes include the removal of the requirement to separately measure and report ineffectiveness and the ability to perform ongoing effectiveness assessments on a qualitative basis. This accounting guidance is effective for public business entities for fiscal years, and interim periods within those years, beginning after December 15, 2018, with earlier adoption permitted. We adopted this accounting guidance in fiscal year 2018. Since there were no active hedge accounting relationships as of the adoption date, there were no adjusting entries required to adjust on a modified retrospective basis.

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 March 2018, the FASB issued new accounting guidance to expand income tax accounting and disclosure guidance on accounting for the income tax effects of tax legislation commonly known as the Tax Cuts and Jobs Act (the “Act”) and among other things allows for a measurement period not to exceed one year for companies to finalize the provisional amounts recorded. We adopted this accounting guidance in fiscal year 2018. See Note 8 for further details.

Variable Interest Entities and Other Investments in Significant Affiliates [Abstract]

VARIABLE INTEREST ENTITIES AND OTHER INVESTMENTS IN SIGNIFICANT AFFILIATES

VIEs

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 March 31, 2018, we had interests in four VIEs of which we are the primary beneficiary, which are described below, and had no interests in VIEs of which we are not the primary beneficiary.

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 holds all of the outstanding shares in Bristow Helicopters Limited (“Bristow Helicopters”). Bristow Aviation’s subsidiaries provide industrial aviation services to clients 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 ($127.7 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 $2.1 billion as of March 31, 2018.

The Company, Caledonia, the E.U. Investor and Bristow Aviation have entered into a shareholder agreement respecting, among other things, the composition 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 owns (1) at least 1,000,000 shares of common stock of the Company or (2) at least 49% of the total outstanding shares of Bristow Aviation.

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. 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 under the put/call agreement limiting our ability to exercise the put/call option is a requirement to consult with the Civil Aviation Authority (the “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 consolidated balance sheets as noncontrolling interest.

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 March 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% (prior to May 2004, the rate was fixed at 12%) by recognizing noncontrolling interest expense on our consolidated statements of operations, with a corresponding increase in noncontrolling interest on our consolidated balance sheets. Prepayments of the guaranteed return element of the call option are reflected as a reduction in noncontrolling interest on our 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.

Changes in the balance for the noncontrolling interest associated with Bristow Aviation are as follows (in thousands):

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 March 31, 2018. BHNL provides industrial aviation services to clients 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 its 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 an interest of 50.17%. PAAN provides industrial aviation services to clients in Nigeria.

The activities that most significantly impact PAAN’s economic performance relate to the day-to-day operation of PAAN, setting of 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.

Other Significant Affiliates — Consolidated

In addition to the VIEs discussed above, we consolidate the entities described below, which were less than 100% owned during fiscal years 2018, 2017 and/or 2016.

Airnorth — As of March 31, 2018, Bristow Helicopters Australia Pty Ltd. (“Bristow Helicopters Australia”) had a 100% interest in Airnorth, a regional fixed wing operator based in Darwin, Northern Territory, Australia with both scheduled and charter services that focus primarily on the energy and mining industries in northern and western Australia as well as international service to Dili, Timor-Leste. Airnorth’s fleet consists of 14 aircraft and its customer base includes many energy companies to which Bristow Group provides helicopter transportation services. In January 2015, Bristow Helicopters Australia acquired an 85% interest in Airnorth, for cash of A$30.3 million ($24.0 million). In November 2015, we purchased the remaining 15% of the outstanding shares of Airnorth for A$7.3 million ($5.3 million) resulting in a reduction of $5.5 million to redeemable noncontrolling interests and an increase of $2.6 million to additional paid-in capital on our consolidated balance sheet. The terms of the purchase agreement for Airnorth included a potential earn out consideration of up to A$17.0 million ($13.0 million) to be paid over four years based in part on the achievement of specified financial performance thresholds and continued employment by the selling shareholders. A portion of the first year earn-out payment of $1.5 million was paid during fiscal year 2016 as Airnorth achieved agreed performance targets. Airnorth did not achieve the performance targets for the second year earn-out payment. In addition, we entered into an agreement with the other shareholders of Capiteq Limited that granted us the right after six months to buy all of their shares (and granted them the right after three years to require us to buy all of their shares) and included transfer restrictions and other customary provisions.

Prior to the acquisition of the remaining 15% of outstanding shares of Airnorth in November 2015, redeemable noncontrolling interests included the third-party noncontrolling interests in Airnorth. The third-party noncontrolling interest holders held a written put option, which allowed them to sell their noncontrolling interest to Bristow Helicopters Australia at any time after the end of the third year after acquisition. In addition to the written put option, Bristow Helicopters Australia held a perpetual call option to acquire the noncontrolling interest after six months. Under each of these alternatives, the exercise price would be based on a contractually defined multiple of cash flows formula (the “Airnorth Redemption Value”), which is not a fair value measurement, and was payable in cash. As the written put option was redeemable at the option of the noncontrolling interest holders, and not solely within Bristow Helicopters Australia’s control, the noncontrolling interest in Airnorth was classified in redeemable noncontrolling interests between the stockholders’ investment and liabilities sections of the consolidated balance sheets. The initial carrying amount of the noncontrolling interest was the fair value of the noncontrolling interest as of the acquisition date.

The noncontrolling interest was adjusted each period for comprehensive income and dividends attributable to the noncontrolling interest and any changes in Bristow Helicopters Australia’s ownership interest in Airnorth, if any. An additional adjustment to the carrying value of the noncontrolling interest was required if the Airnorth Redemption Value exceeded the current carrying value. Changes in the carrying value of the noncontrolling interest related to a change in the Airnorth Redemption Value would be recorded against permanent equity and would not affect net income. While there was no impact on net income, the redeemable noncontrolling interest impacted our calculation of earnings per share. Utilizing the two-class method, we adjusted the numerator of the earnings per share calculation to reflect the changes in the excess, if any, of the Airnorth Redemption Value over the greater of (1) the noncontrolling interest carrying amount or (2) the fair value of the noncontrolling interest on a quarterly basis.

Changes in the balance for the redeemable noncontrolling interest related to Airnorth are as follows (in thousands):

Balance as of March 31, 2015	$	3,339
Noncontrolling interest expense	788
Accretion of noncontrolling interest	1,498
Currency translation	(158		)
Acquisition of remaining 15% of Airnorth	(5,467		)
Balance as of March 31, 2016	$	—

Eastern Airways — As of March 31, 2018, Bristow Helicopters had a 100% interest in Eastern Airways, a regional fixed wing operator based at Humberside Airport located in North Lincolnshire, England with both charter and scheduled services targeting U.K oil and gas industry transportation. In February 2014, Bristow Helicopters acquired a 60% interest in Eastern Airways. In January 2018, Bristow Helicopters acquired the remaining 40% of the outstanding shares of Eastern Airways for nominal consideration. Eastern Airways operates 34 fixed wing aircraft and provides technical support for two fixed wing aircraft. The terms of the purchase agreement for Eastern Airways included potential earn-out consideration of up to £6 million ($7.5 million) to be paid over a three-year period based on the achievement of specified financial performance thresholds through March 31, 2017. None of the earn-out targets were achieved. In addition, Bristow Helicopters entered into agreements with the other shareholders of Eastern Airways that grant Bristow Helicopters the right to buy all of the Eastern Airways shares (and grant them the right after seven years to require Bristow Helicopters to buy all of their shares) and include transfer restrictions and other customary provisions.

The third-party noncontrolling interest holders hold a written put option, which will allow them to sell their noncontrolling interest to Bristow Helicopters at any time after the end of the seventh year after acquisition. In addition to the written put option, Bristow Helicopters holds a perpetual call option to acquire the noncontrolling interest at any time. Under each of these alternatives, the exercise price will be based on a contractually defined multiple of cash flows formula (the “Eastern Redemption Value”), which is not a fair value measurement, and is payable in cash. As the written put option is redeemable at the option of the noncontrolling interest holders, and not solely within Bristow Helicopters control, the noncontrolling interest in Eastern Airways is classified in redeemable noncontrolling interests between the stockholders’ investment and liabilities sections of the consolidated balance sheets. The initial carrying amount of the noncontrolling interest was the fair value of the noncontrolling interest as of the acquisition date.

The noncontrolling interest was adjusted each period for comprehensive income and dividends attributable to the noncontrolling interest and changes in Bristow Helicopters’ ownership interest in Eastern Airways, if any. An additional adjustment to the carrying value of the noncontrolling interest may be required if the Eastern Redemption Value exceeds the current carrying value. Changes in the carrying value of the noncontrolling interest related to a change in the Eastern Redemption Value were recorded against permanent equity and did not affect net income. While there was no impact on net income, the redeemable noncontrolling interest impacted our calculation of earnings per share. Utilizing the two-class method, we adjusted the numerator of the earnings per share calculation to reflect the changes in the excess, if any, of the Eastern Redemption Value over the greater of (1) the noncontrolling interest carrying amount or (2) the fair value of the noncontrolling interest on a quarterly basis.

Changes in the balance for the redeemable noncontrolling interest related to Eastern Airways are as follows (in thousands):

Balance as of March 31, 2015	$	22,885
Noncontrolling interest expense	(6,499		)

Prior to our acquisition of the remaining 40% outstanding shares in fiscal year 2018, Eastern Airways was consolidated based on the rights to manage the day-to-day operations of the company which were granted under a shareholders’ agreement and our ability to buy all of their Eastern Airways shares under a put/call agreement.

Aviashelf — Bristow Aviation has an indirect 48.5% interest in Aviashelf Aviation Co. (“Aviashelf”), a Russian helicopter company. Additionally, we own 60% of two U.K. joint venture companies, Bristow Helicopters Leasing Ltd. and Sakhalin Bristow Air Services Ltd. These two U.K. companies lease aircraft to Aviashelf which holds the client contracts for our Russian operations. Aviashelf is consolidated based on the ability of certain consolidated subsidiaries of Bristow Aviation to control the vote on a majority of the shares of Aviashelf, rights to manage the day to day operations of the company which were granted under a shareholders’ agreement, and our ability to acquire an additional 8.5% interest in Aviashelf under a put/call option agreement.

Other Significant Affiliates — Unconsolidated

We have investments in other significant unconsolidated affiliates as described below.

Cougar — We own a 25% voting interest and a 40% economic interest in Cougar Helicopters Inc. (“Cougar”), the largest offshore energy and SAR helicopter service provider in Canada. Cougar’s operations are primarily focused on serving the offshore oil and gas industry off Canada’s Atlantic coast and in the Arctic. Cougar operates eight helicopters leased from us on a long-term basis. We also lease maintenance and SAR facilities located in St. John’s, Newfoundland and Labrador and Halifax, Nova Scotia to Cougar on a long-term basis. The terms of the purchase agreement for Cougar include a potential earn-out of $40 million payable over three years based on Cougar achieving certain agreed performance targets. The first year and second year earn-out payments of $6.0 million and $8.0 million were paid in March 2014 and April 2015, respectively, as Cougar achieved agreed performance targets. The third year earn-out was achieved as Cougar achieved agreed performance targets of which $10 million was paid in April 2016 and $16 million was paid in April 2017. The fair value of the earn-out was $16.0 million as of March 31, 2017 and is included in short-term borrowings and current maturities of long-term debt on our consolidated balance sheet. The investment in Cougar is accounted for under the equity method. As of March 31, 2018 and 2017, the investment in Cougar was $54.0 million and $56.9 million, respectively, and is included on our consolidated balance sheets in investment in unconsolidated affiliates. Due to timing differences in our financial reporting requirements, we record our share of Cougar’s financial results in earnings from unconsolidated affiliates on a three-month delay. Additionally, we have leased aircraft from VIH Aviation Group, which is a related party due to common owners of Cougar, and paid lease fees of $19.3 million, $12.5 million and $6.5 million in fiscal years 2018, 2017 and 2016, respectively. Additionally, we paid $0.5 million and $2.6 million in fiscal years 2017 and 2016, respectively, to VIH Aerospace Inc., another related party with common owners of Cougar, for SAR and other equipment. In July 2016 we began leasing a facility in Galliano, Louisiana from VIH Helicopters USA, Inc., another related party with common owners of Cougar, and paid $0.2 million and $0.1 million in lease fees during fiscal years 2018 and 2017, respectively.

Líder — 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. Líder’s fleet has 41 helicopters and 20 fixed wing aircraft (including owned and managed aircraft). The investment in Líder is accounted for under the equity method. As of March 31, 2018 and 2017, the investment in Líder was $62.3 million and $143.5 million, respectively, and is included in our consolidated balance sheets in investment in unconsolidated affiliates. As discussed in Note 1, we recorded an $85.7 million impairment to our investment in Líder in fiscal year 2018.

PAS — We have a 25% interest in Petroleum Air Services (“PAS”), an Egyptian corporation that provides helicopter and fixed wing transportation to the offshore energy industry in Egypt. Additionally, spare fixed wing capacity is chartered to tourism operators. PAS owns 48 aircraft. PAS is accounted for under the cost method as we are unable to exert significant influence over its operations.

Other — Historically, in addition to the expansion of our business through purchases of new and used aircraft, we have also established new joint ventures with local partners or purchased significant ownership interests in companies with ongoing helicopter operations, particularly in countries where we have no operations or our operations are limited in scope, and we continue to evaluate similar opportunities which could enhance our operations. Where we believe that it is probable that an equity method investment will result, the costs associated with such investment evaluations are deferred and included in investment in unconsolidated affiliates on the consolidated balance sheets. For each investment evaluated, an impairment of deferred costs is recognized in the period in which we determine that it is no longer probable an equity method investment will result. As of March 31, 2018 and 2017, we had no amounts in investment in unconsolidated affiliates in the process of being evaluated.

Our percentage of economic ownership and investment balances for the unconsolidated affiliates are as follows:

_______________

⁽¹⁾  During fiscal year 2016, we took delivery of two aircraft that were purchased using short-term debt borrowings for the final payments of the aircraft. As of March 31, 2017, the short-term borrowings for these aircraft have been paid.

⁽²⁾  During fiscal years 2018, 2017 and 2016, we spent $2.3 million, $71.4 million and $202.7 million, respectively, on progress payments for aircraft to be delivered in future periods.

The following table presents details on the aircraft sold or disposed of and impairments on assets held for sale during fiscal years 2018, 2017 and 2016:

_______________ 

⁽¹⁾  During fiscal year 2016, three of these aircraft were sold and leased back and we received $29.2 million in proceeds for the aircraft. We did not enter into any sale leasebacks during fiscal years 2017 and 2018.

⁽²⁾  Includes $6.5 million impairment of the Bristow Academy disposal group for fiscal year 2018.

In addition to capital expenditures and sale or disposal of assets, the following items impacted property and equipment during fiscal year 2018:

• We transferred 4 aircraft to held for sale and reduced property and equipment by $9.3 million.

In addition to capital expenditures and sale or disposal of assets, the following items impacted property and equipment during fiscal year 2017:

• We recorded accelerated depreciation of $10.4 million on 11 medium aircraft operating in our Europe Caspian, Americas and Africa regions as our management decided to exit these model types earlier than originally anticipated. In certain instances the salvage values of some aircraft were also adjusted to reflect our expectation of sales values in the current market.

• We transferred 12 aircraft to held for sale and reduced property and equipment by $19.7 million.

In addition to capital expenditures and sale or disposal of assets, the following items impacted property and equipment during fiscal year 2016:

• We recorded accelerated depreciation of $28.7 million on 18 medium, four large and one fixed wing aircraft operating in our Europe Caspian, Americas, Africa and Asia Pacific regions as our management decided to exit these model types earlier than originally anticipated. In certain instances the salvage values of some aircraft were also adjusted to reflect our expectation of sales values in the current market.

• We took delivery and entered into leases for the remaining two aircraft related to the deferred sale leaseback and removed a total of $75.8 million and $74.3 million, respectively, from construction in progress and deferred sale leaseback advance on our consolidated balance sheet. See Note 1 for further details on the deferred sale leaseback advance.

• We took delivery of two large aircraft which we purchased using short-term debt borrowings for the final payments of the aircraft of $24.4 million.

• We transferred 35 aircraft to held for sale and reduced property and equipment by $83.6 million.

During fiscal years 2018, 2017 and 2016, we saw a deterioration in market sales for aircraft resulting mostly from an increase in idle aircraft and reduced demand across the offshore energy market. While other markets exist for certain aircraft model types, including utility, firefighting, government, VIP transportation and tourism, the market for certain model type aircraft slowed. As a result of these market changes, changes in estimated salvage values of our fleet of operational aircraft and other changes in the timing of exiting certain aircraft from our operations, we recorded impairments and additional depreciation expense discussed above. For further details, see Note 1 for a discussion on impairments of property and equipment.

Assets Held for Sale

Assets held for sale are classified as current assets on our consolidated balance sheets and recorded at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. As of March 31, 2018 and 2017, we had 11 and 20 aircraft, for $30.3 million and $38.2 million, classified as held for sale, respectively. We intend to sell or otherwise dispose of these assets during the next fiscal year. As presented in the table above, we recorded impairment charges of $15.9 million, $12.5 million and $29.6 million to reduce the carrying value of eight, 14 and 16 aircraft held for sale during fiscal years 2018, 2017 and 2016, respectively. These impairment charges were included in loss on disposal of assets in the consolidated statements of operations.

The impairment charges recorded on held for sale aircraft during fiscal years 2018, 2017 and 2016 related primarily to older model aircraft types our management decided to dispose of earlier than originally anticipated in addition to the impact of changes in expected sales prices in the aircraft aftermarket resulting from the oil and gas market downturn.

On November 1, 2017, we sold our 100% interest in Bristow Academy, including all of its aircraft, for a minimum of $1.5 million to be received over a maximum of four years with potential additional consideration based on Bristow Academy’s financial performance. The sale of this non-core business resulted in total charges recorded in the fiscal year 2018 of $7.2 million, which resulted from the combined loss on the sale and related impairment of assets included in loss on disposal of assets on our consolidated statement of operations. Bristow Academy is included in Corporate and other in Note 11.

OEM Cost Recoveries

During fiscal year 2018, we reached agreements with OEMs to recover $136.0 million related to ongoing aircraft issues, of which $125.0 million was realized and resulted in an increase in cash. 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. 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 have allocated the $94.5 million as a reduction in carrying value by reducing the historical acquisition value of each affected aircraft on a pro-rata basis utilizing the historical acquisition value of the aircraft. We revised our salvage values for each affected aircraft by reducing the historical acquisition value by the applicable amount and applying our stated salvage value percentage for owned aircraft of 50%. 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 will result in a reduction of depreciation expense of $8.5 million during fiscal year 2019, $8.4 million during fiscal year 2020, $5.6 million during fiscal year 2021 and $21.3 million during fiscal year 2022 and beyond. For the leased aircraft, we will recognize the remaining deferred liability of $13.9 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 $7.9 million during fiscal year 2019, $4.0 million during fiscal year 2020 and $2.0 million during fiscal year 2021.

During May 2018, we realized 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. We expect to realize the $11.0 million recovery in earnings during fiscal year 2019 as follows: $7.6 million increase in revenue and $1.1 million decrease in direct cost in the first quarter, $1.0 million decrease in direct cost in the second quarter, $1.0 million decrease in direct cost in the third quarter and $0.3 million decrease in direct cost in the fourth quarter. 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 that we have recovered from the OEM.

Short-term borrowings reclassification — 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 the Explanatory Note included elsewhere in this Annual Report, on May 11, 2019, 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. Each of the commencement of the Chapter 11 Cases and the delivery of this Amended 10-K 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 March 31, 2018 should be reclassified from long-term to short-term within this Amended 10-K on our consolidated balance sheet.

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 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.

8.75% Senior Secured Notes — On March 6, 2018, we issued and sold $350 million of 8.75% Senior Secured Notes in a private offering to eligible purchasers pursuant to Rule 144A and Regulation S under the Securities Act of 1933, as amended, for proceeds of $346.6 million and simultaneously entered into an indenture (the “Indenture”) with U.S. Bank National Association, as trustee and as collateral agent. The 8.75% Senior Secured Notes were initially fully and unconditionally guaranteed, jointly and severally, on a senior secured basis by certain of our U.S. subsidiaries (the “Guarantor Subsidiaries”) and will be secured by first priority security interests on substantially all of the tangible and intangible personal property of Bristow Group Inc. and the Guarantor Subsidiaries (other than certain excluded assets) (the “Collateral”) as collateral security for their obligations under the 8.75% Senior Secured Notes, subject to certain permitted encumbrances and exceptions. Certain of the security interests were granted in connection with the execution and delivery of the Indenture, while security interests anticipated to cover approximately 77 aircraft will be granted within the periods described in the Indenture.

The 8.75% Senior Secured Notes bear interest at a rate of 8.75% per year, payable semi-annually in arrears on March 1 and September 1 of each year, beginning on September 1, 2018. The 8.75% Senior Secured Notes will mature on March 1, 2023, subject to earlier mandatory redemption if more than $125 million principal amount of the 6¼% Senior Notes due 2022 (the “6¼% Senior Notes”) plus the principal amount of any indebtedness incurred to refinance the 6¼% Senior Notes that matures or is required to be repaid prior to June 1, 2023 remains outstanding as of June 30, 2022. We may redeem all or a portion of the 8.75% Senior Secured Notes at any time on or after March 1, 2020 at the applicable redemption price, plus accrued and unpaid interest, if any, to the redemption date. At any time prior to March 1, 2020, we may redeem all or a portion of the 8.75% Senior Secured Notes at a price equal to 100% of the principal amount of 8.75% Senior Secured Notes to be redeemed plus a “make-whole” premium, plus accrued and unpaid interest, if any, to the redemption date. In addition, on one or more occasions, on or prior to March 1, 2020, we may redeem up to 35% of the aggregate principal amount of the 8.75% Senior Secured Notes at a redemption price equal to 108.75% of the principal amount of the 8.75% Senior Secured Notes to be redeemed, plus accrued and unpaid interest, if any, to the redemption date, with an amount of cash not greater than the net cash proceeds of certain qualified equity offerings by us.

The Indenture contains customary covenants that, among other things, limit our ability to incur additional liens or financial indebtedness and to sell or otherwise transfer the Collateral, including the pledged aircraft. The Indenture also contains customary events of default. If an event of default occurs and is continuing, the Trustee or the holders of at least 25% in principal amount of the then outstanding 8.75% Senior Secured Notes may declare the unpaid principal of, and any premium and accrued and unpaid interest on, all the 8.75% Senior Secured Notes then outstanding to be due and payable immediately. In case of certain events of bankruptcy, insolvency or reorganization with respect to Bristow Group Inc., any Guarantor Subsidiary or any significant subsidiary, all of the principal of and accrued and unpaid interest on the 8.75% Senior Secured Notes will automatically become due and payable. Upon a change of control (as defined in the Indenture), we will be required to make an offer to repurchase all or any part of each 8.75% Senior Secured Notes at an offer price in cash equal to 101% of the aggregate principal amount, plus accrued and unpaid interest, if any, to the date of repurchase.

The proceeds of the 8.75% Senior Secured Notes were used, among other things, to repay the remaining obligations of the $350 million term loan (the “Term Loan”) discussed below, to cash collateralize certain outstanding letters of credit existing under the $400 million revolving credit facility with a subfacility of $50 million for letters of credit (the “Revolving Credit Facility”) discussed below and for general corporate purposes.

4½% Convertible Senior Notes — On December 18, 2017, we issued and sold $143.8 million of 4½% Convertible Senior Notes due 2023 (the “4½% Convertible Senior Notes”). The 4½% Convertible Senior Notes are our unsecured senior obligations and are jointly and severally guaranteed on a senior unsecured basis by the Guarantor Subsidiaries. The 4½% Convertible Senior Notes bear interest at a rate of 4.50% per year and interest is payable on June 1 and December 1 of each year, beginning on June 1, 2018. The 4½% Convertible Senior Notes mature on June 1, 2023 and may not be redeemed by us prior to maturity.

The 4½% Convertible Senior Notes are convertible into cash, shares of our common stock or a combination of cash and shares of our common stock, at our election. We have initially elected combination settlement. The initial conversion price of the 4½% Convertible Senior Notes is approximately $15.64 (subject to adjustment in certain circumstances), based on the initial conversion rate of 63.9488 common shares per $1,000 principal amount of 4½% Convertible Senior Notes. Prior to December 1, 2022, the 4½% Convertible Senior Notes will be convertible only upon the occurrence of certain events and during certain periods, and thereafter, until the close of business on the second scheduled trading day immediately preceding the maturity date. The 4½% Convertible Senior Notes are senior unsecured obligations. As of March 31, 2018, the if-converted value of the 4½% Convertible Senior Notes did not exceed the principal balance.

The proceeds of the 4½% Convertible Senior Notes were used to repay $89.6 million of the Term Loan as discussed below and to pay the $10.1 million cost of the convertible note hedge transaction described below, with the remainder available for general corporate purposes.

Accounting standards require that convertible debt which may be settled in cash upon conversion (including partial cash settlement) be accounted for with a liability component based on the fair value of similar nonconvertible debt and an equity component based on the excess of the initial proceeds from the convertible debt over the liability component. Such excess represents proceeds related to the conversion option and is recorded as additional paid-in capital. The liability is recorded at a discount, which is then amortized as additional non-cash interest expense over the term of the 4½% Convertible Senior Notes. The balances of the debt and equity components of the 4½% Convertible Senior Notes as of March 31, 2018 are as follows (in thousands):

Equity component - net carrying value (1)	$	36,778
Debt component:
Face amount due at maturity	$	143,750
Unamortized discount	(36,353		)
Debt component - net carrying value	$	107,397

_____________ 

⁽¹⁾ Net of equity issuance costs of $1.0 million.

The remaining debt discount is being amortized to interest expense over the term of the 4½% Convertible Senior Notes using the effective interest rate. The effective interest rate for the fiscal year 2018 was 11.0%. Interest expense related to our 4½% Convertible Senior Notes for fiscal year 2018 was as follows (in thousands):

Contractual coupon interest	$	1,851
Amortization of debt discount	1,454
Total interest expense	$	3,305

Convertible Note Call Spread Overlay — Concurrent with the issuance of the 4½% Convertible Senior Notes, we entered into privately negotiated convertible note hedge transactions (the “Note Hedge Transactions”) and warrant transactions (the “Warrant Transactions”) with each of Credit Suisse Capital LLC, Barclays Bank PLC, Citibank, N.A. and JPMorgan Chase Bank, National Association (the “Option Counterparties”). These transactions represent a Call Spread Overlay, whereby the cost of the Note Hedge Transactions we purchased to cover the cash outlay upon conversion of the 4½% Convertible Senior Notes was reduced by the sales price of the Warrant Transactions. Each of these transactions is described below.

The Note Hedge Transactions cost an aggregate $40.4 million and are expected generally to reduce the potential dilution and/or offset the cash payments we are required to make in excess of the principal amount upon conversion of the 4½% Convertible Senior Notes in the event that the market price of our common stock is greater than the strike price of the Note Hedge Transactions, which is initially $15.64 (subject to adjustment), corresponding approximately to the initial conversion price of the 4½% Convertible Senior Notes. The Note Hedge Transactions have been accounted for by recording the cost as a reduction to additional paid-in capital.

We received proceeds of $30.3 million for the Warrant Transactions, in which we sold net-share-settled warrants to the Option Counterparties in an amount equal to the number of shares of our common stock initially underlying the 4½% Convertible Senior Notes, subject to customary anti-dilution adjustments. The strike price of the warrants is $20.02 per share (subject to adjustment), which is 60% above the last reported sale price of our common stock on the New York Stock Exchange on December 13, 2017. The Warrant Transactions could have a dilutive effect to our stockholders to the extent the market price per share of our common stock, as measured under the terms of the Warrant Transactions, exceeds the applicable strike price of the warrants. The Warrant Transactions have been accounted for by recording the proceeds received as additional paid-in capital.

The Note Hedge Transactions and the Warrant Transactions are separate transactions, in each case entered into by us with the Option Counterparties, and are not part of the terms of the 4½% Convertible Senior Notes and will not affect any holder’s rights under the 4½% Convertible Senior Notes.

6¼% Senior Notes — On October 12, 2012, we completed an offering of $450 million of the 6¼% Senior Notes. The 6¼% Senior Notes are senior unsecured obligations and are jointly and severally guaranteed on a senior unsecured basis by the Guarantor Subsidiaries. The indenture for our 6¼% Senior Notes includes restrictive covenants which limit, among other things, our ability to incur additional debt, issue disqualified stock, pay dividends, repurchase stock, invest in other entities, sell assets, incur additional liens or security, merge or consolidate the Company and enter into transactions with affiliates. Interest on the 6¼% Senior Notes is payable on April 15 and October 15 of each year and the 6¼% Senior Notes mature on October 15, 2022. We may redeem any of the 6¼% Senior Notes at any time, in whole or part, in cash, at certain redemption prices plus accrued and unpaid interest, if any, to the date of redemption. We incurred financing fees of $7.4 million, that are included as deferred financing fees in other assets in the consolidated balance sheets which we will amortize as interest expense in the consolidated statements of operations over the life of the 6¼% Senior Notes.

Revolving Credit Facility and Term Loan — Our amended and restated revolving credit and term loan agreement, included the Revolving Credit Facility and the Term Loan (together with the Revolving Credit Facility and the Term Loan Credit Facility described below, the “Senior Credit Facilities”).

During fiscal year 2018, we had borrowings of $174.8 million under the Revolving Credit Facility and made payments of $313.9 million to fully repay borrowings under the Revolving Credit Facility. Additionally, during fiscal year 2018 we made payments of $261.9 million to fully repay our borrowings under the Term Loan. In March 2018, we terminated both the Revolving Credit Facility and Term Loan and cash collateralized all then-outstanding letters of credit issued thereunder.

Term Loan Credit Facility — On November 5, 2015, we entered into a senior secured term loan credit agreement providing for $200 million of term loan commitments (the “Term Loan Credit Facility”).

Borrowings under the Term Loan Credit Facility were repaid in full and the facility was terminated in October 2017.

Lombard Debt — On November 11, 2016, certain of our subsidiaries entered into two, seven-year British pound sterling funded secured equipment term loans for an aggregate $200 million U.S. dollar equivalent with Lombard North Central Plc, a part of the Royal Bank of Scotland (the “Lombard Debt”). In December 2016, the first loan amount of $109.9 million (GBP 89.1 million) funded and the borrower prepaid scheduled principal payments of $4.5 million (GBP 3.7 million). The proceeds from this financing were used to finance the purchase by the borrower thereunder of three SAR aircraft utilized for our U.K. SAR contract from a subsidiary. In January 2017, the second loan amount of $90.1 million (GBP 72.4 million) funded. The proceeds from this financing were used to finance the purchase by the borrower thereunder of five SAR aircraft utilized for our U.K. SAR contract from a subsidiary. The borrowers’ respective obligations under the financings are guaranteed by the Company, and each financing is secured by the aircraft purchased by the applicable borrower with the proceeds of its loan. The credit agreements governing the Lombard Debt include covenants, including requirements to maintain, register and insure the respective SAR aircraft secured thereunder, and restrictions on the respective borrower thereunder to incur additional liens on or sell the respective SAR aircraft secured thereunder (except to the Company and its subsidiaries). Borrowings under the financings bear interest at an interest rate equal to the ICE Benchmark Administration Limited LIBOR (or the successor thereto) plus 2.25% per annum. The weighted-average interest rate was 2.96% and 2.57% as of March 31, 2018 and 2017, respectively. The financing which funded in December 2016 matures in December 2023 and the financing which funded in January 2017 matures in January 2024.

Macquarie Debt — On February 1, 2017, one of our wholly-owned subsidiaries entered into a term loan credit agreement for a $200 millionfive-year secured equipment term loan with Macquarie Bank Limited (the “Macquarie Debt”). In conjunction with closing and funding under such term loan, we have agreed to lease five helicopters for lease terms ranging from 60 to 63 months from Wells Fargo Bank Northwest, N.A., acting as owner trustee for Macquarie Aerospace Inc., an affiliate of Macquarie Bank Limited. The borrower’s obligations under the credit agreement are guaranteed by the Company and secured by 20 oil and gas aircraft. The financing funded on March 7, 2017. Borrowings under the financing bear interest at an interest rate equal to the ICE Benchmark Administration Limited LIBOR (or the successor thereto) plus 5.35% per annum. The interest rate was 7.00% and 6.24% as of March 31, 2018 and 2017, respectively. The proceeds from the financing were used to repay $154.1 million of the Term Loan Credit Facility and $45.9 million of the Term Loan.

The credit agreement governing the Macquarie Debt includes covenants, including requirements to maintain, register and insure the respective aircraft secured thereunder, and restrictions on the respective borrower thereunder to incur additional liens on or sell the respective aircraft secured thereunder (except to the Company and its subsidiaries). The Macquarie Debt matures in March 2022.

PK Air Debt — On July 17, 2017, a wholly-owned subsidiary entered into a term loan credit agreement with PK AirFinance S.à r.l., as agent, and PK Transportation Finance Ireland Limited, as lender, and other lenders from time to time party thereto, which provided for commitments in an aggregate amount of up to $230 million to make up to 24 term loans, each of which was made in respect of an aircraft pledged as collateral for all of the term loans. The term loans are also secured by a pledge of all shares of the borrower and any other assets of the borrower and are guaranteed by the Company. The financing funded in two tranches in September 2017 and proceeds were used to repay $17.0 million of the Term Loan Credit Facility, $93.7 million of the Term Loan and $103.0 million of the Revolving Credit Facility.

Each term loan bears interest at an interest rate equal to, at the borrower’s option, a floating rate of one-month LIBOR plus a margin of 5% per annum (the “Margin”), subject to certain costs of funds adjustments, determined two business days before the borrowing date of each term loan, or a fixed rate based on a notional interest rate swap of 12 30-day months in respect of such term loan with a floating rate of interest based on one-month LIBOR, plus the Margin. The weighted-average interest rate was 6.79% as of March 31, 2018.

The borrower is required to repay each term loan on an annuity basis, payable monthly in arrears starting on the seventh month following the date of the borrowing of such term loan, with a final payment of 53% of the initial amount of such term loan due on the 70th month following the date of the borrowing of such term loan.

In connection with the PK AirFinance term loan credit agreement, the borrower guarantees certain of its direct parent’s obligations under existing aircraft operating leases up to a capped amount.

AirnorthDebt—Airnorth’s outstanding debt includes interest bearing term loans of $13.8 million as of March 31, 2018. The term loans primarily relate to the purchase of aircraft, have a remaining term of approximately two to six years, and consist of a term loan with interest at LIBOR plus a margin of 2.85% and two term loans each with a fixed rate of 3.1% plus the Reserve Bank of Australia cash rate of 2.0%. The term loans have customary covenants, including certain financial covenants, and varying principal payments.

Eastern Airways Debt —Eastern Airways’ outstanding debt includes interest bearing term loans and borrowings under a revolving credit facility totaling $14.5 million as of March 31, 2018. The term loans were used to refinance other Eastern indebtedness in October 2015 and bear interest at LIBOR plus a margin of 1.75%. The interest rate on the term loans was 2.23% as of March 31, 2018. These term loans have quarterly principal payments and mature on August 31, 2018. Borrowings under the revolving credit facility are used for general corporate, working capital and capital expenditure purposes, and bear interest at LIBOR plus a margin of 1.75%. All outstanding obligations under the revolving credit facility will mature on August 31, 2018.

Other Debt — Other debt primarily includes amounts payable relating to the third year earn-out payment for our investment in Cougar totaling $16.0 million that was paid in April 2017.

Other Matters — Aggregate annual maturities (which excludes unamortized discount of $36.4 million and unamortized debt issuance costs of $27.5 million) for all debt for the next five fiscal years and thereafter are as follows (in thousands):

Fiscal year ending March 31

FAIR VALUE DISCLOSURES

Fair Value Disclosures [Abstract]

FAIR VALUE DISCLOSURES

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 as its fair value.

The following table summarizes the assets as of March 31, 2018, valued at fair value on a non-recurring basis (in thousands):

	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Balance as of March 31, 2018		Total Loss for Fiscal Year 2018

Total assets	$	—	$	30,863	$	62,267	$	93,130	$	(107,253	)

The following table summarizes the assets as of March 31, 2017, valued at fair value on a non-recurring basis (in thousands):

	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Balance as of March 31, 2017		Total Loss for Fiscal Year 2017
Inventories	$	—	$	46,568	$	—	$	46,568	$	(7,572	)
Assets held for sale	—		38,246		—		38,246		(12,450		)

Total assets	$	—	$	84,814	$	19,798	$	104,612	$	(28,728	)

The fair value of inventories using Level 2 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 timeframe 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. See Note 1 for further discussion of the impairment of inventories.

The fair value of assets held for sale using Level 2 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. See Note 3 for details on assets held for sale.

The fair value of investment in affiliates is estimated using a variety of valuation methods, including the income and market approaches. These estimates of fair value include unobservable inputs, representative of Level 3 fair value measurement, including assumptions related to future performance, such as projected demand for services and rates. For further details on our investment in unconsolidated affiliates, see Notes 1 and 2.

The fair value of other intangible assets and goodwill is estimated using a variety of valuation methods, including the income and market approaches. These estimates of fair value include unobservable inputs, representative of Level 3 fair value measurement, including assumptions related to future performance, such as projected demand for our services and rates. For further details on other intangible assets and goodwill, see Note 1.

The rabbi trust investments consist of cash and mutual funds whose fair value are based on quoted prices in active markets for identical assets, and are designated as Level 1 within the valuation hierarchy. The rabbi trust holds investments related to our non-qualified deferred compensation plan for our senior executives as discussed in Note 9. The derivative financial instrument consists of foreign currency put option contracts whose fair value is determined by quoted market prices of the same or similar instruments, adjusted for counterparty risk. See Note 6 for a discussion of our derivative financial instruments.

Fair Value of Debt

The fair value of our debt has been estimated in accordance with the accounting standard regarding fair value. The fair value of our fixed rate long-term debt is estimated based on quoted market prices and has not been updated for any possible acceleration provisions in our debt instruments.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

DERIVATIVE FINANCIAL INSTRUMENTS

Note 6 — 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, we entered into foreign currency put option contracts of £5 million per month through November 2018 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.

The following table presents the balance sheet location and fair value of the portions of our derivative instruments that were designated as hedging instruments as of March 31, 2018 (in thousands):

	Derivatives designated as hedging instruments under ASC 815		Derivatives not designated as hedging instruments under ASC 815		Gross amounts of recognized assets and liabilities		Gross amounts offset in the Balance Sheet		Net amounts of assets and liabilities presented in the Balance Sheet
Prepaid expenses and other current assets	$	718	$	—	$	718	$	—	$	718
Net	$	718	$	—	$	718	$	—	$	718

The following table presents the impact that derivative instruments, designated as cash flow hedges, had on our accumulated other comprehensive loss (net of tax) and our consolidated statements of operations for fiscal year 2018 (in thousands):

				Financial statement location
Amount of loss recognized in accumulated other comprehensive loss	$	(414	)	Accumulated other comprehensive loss
Amount of loss reclassified from accumulated other comprehensive loss into earnings	$	(68	)	Statement of operations

We estimate that $0.3 million of net losses in accumulated other comprehensive loss associated with our derivative instruments is expected to be reclassified into earnings within the next twelve months.

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 March 31, 2018, we had 27 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.

⁽¹⁾  Includes $98.0 million for five aircraft orders that can be cancelled prior to the delivery dates. We have made non-refundable deposits of $4.5 million related to these aircraft.

⁽²⁾  Includes progress payments on aircraft scheduled to be delivered in future periods only if options are exercised.

The following chart presents an analysis of our aircraft orders and options during fiscal years 2018, 2017 and 2016:

We periodically purchase aircraft for which we have no orders. During fiscal year 2018, we did not purchase any aircraft for which we did not have an order. During both fiscal years 2017 and 2016, we purchased one aircraft for which we did not have an order.

Operating Leases — We have non-cancelable operating leases in connection with the lease of certain equipment, land and facilities, including leases for aircraft. Rental expense incurred under all operating leases was $208.7 million, $212.6 million and $211.8 million in fiscal years 2018, 2017 and 2016, respectively. Rental expense incurred under operating leases for aircraft was $181.3 million, $188.2 million and $184.0 million in fiscal years 2018, 2017 and 2016, respectively. As of March 31, 2018, aggregate future payments under all non-cancelable operating leases that have initial or remaining terms in excess of one year, including leases for 86 aircraft, are as follows (in thousands):

	Aircraft		Other		Total
Fiscal year ending March 31,

	$	366,210	$	75,422	$	441,632

In fiscal year 2016, we sold three aircraft for $29.2 million and entered into separate agreements to lease these aircraft back. We did not enter into any sale leasebacks during fiscal years 2018 or 2017.

The aircraft leases range from base terms of up to 181 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. These leases are included in the amounts disclosed above. 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 March 31, 2018:

End of Lease Term	Number of Aircraft
Fiscal year 2019 to fiscal year 2020	43
Fiscal year 2021 to fiscal year 2023	32
Fiscal year 2024 to fiscal year 2026	11
	86

Employee Agreements — Approximately 54% of our employees are represented by collective bargaining agreements and/or unions with 86% of these employees being represented by collective bargaining agreements and/or unions that have expired or will expire in one year. These agreements generally include annual escalations of up to 3%. Periodically, certain groups of our employees who are not covered by a collective bargaining agreement consider entering into such an agreement. We also have employment agreements with members of senior management. For discussion on separation programs between the Company and its employees, see Note 9.

Environmental Contingencies — The U.S. Environmental Protection Agency (the “EPA”) has in the past notified us that we are a potential responsible party, or PRP, at three former waste disposal facilities that are on the National Priorities List of contaminated sites. Under the federal Comprehensive Environmental Response, Compensation and Liability Act, also known as the Superfund law, persons who are identified as PRPs may be subject to strict, joint and several liability for the costs of cleaning up environmental contamination resulting from releases of hazardous substances at National Priorities List sites. 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.

Other Purchase Obligations — As of March 31, 2018, we had $48.3 million of other purchase obligations representing 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.

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.

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 the Norway Aviation Agency issued safety and operational directives that detail the conditions to apply for safe return to service of H225LP and AS332L2 model aircraft, where operators wish to do so. We continue not to operate for commercial purposes our 24 H225LP model aircraft. We are carefully evaluating next steps and demand for the H225LP model aircraft in our oil and gas and SAR operations worldwide, with the safety of passengers and crews remaining our highest priority.

Separately, our efforts to successfully integrate AW189 aircraft into service for the U.K. SAR contract have been delayed due to a product improvement plan with the aircraft. As a result, the acceptance of four AW189 aircraft will be pushed to later dates. We 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 in May 2018. For further details on the accounting for these recoveries, see Note 3.

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 March 31, 2018 to be approximately $5 million to $6 million.

In connection with the Bristow Norway acquisition in October 2008, we granted the former partner in this joint venture an option that if exercised would require us to acquire up to five aircraft at fair value upon the expiration of the lease terms for such aircraft. One of the options was exercised in December 2009 and two of the options expired. The remaining aircraft leases expire in August 2018. We are currently unable to estimate the fair value of these aircraft. While we do not currently expect to be required to purchase these aircraft, the former joint venture partner has until May 31, 2018 to notify us. If the joint venture partner does not exercise its option, it is our intent to return the aircraft after the leases expire in August 2018.

We are a defendant in certain claims and litigation arising out of operations in the normal course of business. In the opinion of management, uninsured losses, if any, will not be material to our financial position, results of operations or cash flows.

TAXES

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 (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 that will be applicable to us beginning in fiscal year 2019: (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. 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. Consistent with guidance in SAB 118, we recorded provisional amounts for the transition tax on undistributed earnings of $52.9 million, which was partially offset by foreign tax credits of $22.6 million. We also recorded $53.0 million tax benefit as a result of the revaluation of our net deferred tax liabilities. The provisional amounts incorporate assumptions made based upon our current interpretation of the Act and may change as we receive additional clarification and implementation guidance.

We are continuing to analyze additional information to determine the final impact as well as other impacts of the Act. Any adjustments recorded to the provisional amounts will be included in income from operations as an adjustment to our fiscal year 2019 financial statements.

The components of deferred tax assets and liabilities are as follows (in thousands):

Net deferred tax liabilities	$	(74,268	)	$	(124,579	)

Companies may use foreign tax credits to offset the U.S. income taxes due on income earned from foreign sources. However, the credit that may be claimed for a particular taxable year is limited by the total income tax on the U.S. income tax return as well as by the ratio of foreign source net income in each statutory category to total net income. The amount of creditable foreign taxes available for the taxable year that exceeds the limitation (i.e., “excess foreign tax credits”) may be carried back one year and forward ten years. We have $9.1 million of excess foreign tax credits as of March 31, 2018, all of which will expire in fiscal year 2025. As of March 31, 2018, we have $149.0 million of net operating losses in the U.S., of which $2.5 million will expire in fiscal year 2036, $119.7 million will expire in fiscal year 2037 and $26.8 million will expire in fiscal year 2038. In addition, we have net operating losses in certain states totaling $199.7 million which will begin to expire in fiscal year 2022.

We record a valuation allowance when it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of the deferred tax assets depends on the ability to generate sufficient taxable income of the appropriate character in the future and in the appropriate taxing jurisdictions. As of March 31, 2018, valuation allowances were $50.5 million for foreign operating loss carryforwards, $12.3 million for state operating loss carryforwards and $9.1 million for foreign tax credits.

The following table is a rollforward of the deferred tax valuation allowance (in thousands):

The reconciliation of the U.S. Federal statutory tax rate to the effective income tax rate for the (provision) benefit for income taxes is shown below:

	Fiscal Year Ended March 31,
	2018		2017		2016
Statutory rate	31.6	%	35.0	%	35.0	%
Effect of U.S. tax reform	9.9	%	—	%	—	%
Net foreign tax on non-U.S. earnings	0.8	%	(0.5	)%	(8.4	)%
Benefit of foreign tax deduction in the U.S.	—	%	2.5	%	2.6	%
Foreign earnings indefinitely reinvested abroad	(8.2	)%	(1.1	)%	15.9	%
Change in valuation allowance	1.1	%	(25.7	)%	(25.3	)%
Foreign earnings that are currently taxed in the U.S.	(32.9	)%	(28.3	)%	(7.9	)%
Effect of change in foreign statutory corporate income tax rates	—	%	(0.2	)%	1.1	%
Impairment of foreign investments	11.8	%	—	%	—	%
Goodwill impairment	—	%	(1.0	)%	(11.8	)%
Changes in tax reserves	(2.3	)%	(0.2	)%	(0.5	)%
Other, net	1.7	%	(3.1	)%	1.9	%
Effective tax rate	13.5	%	(22.6	)%	2.6	%

In fiscal year 2018, our effective tax rate is 13.5% and includes: (i) tax benefit of $27.0 million related to the impairment of our equity investment in Líder; (ii) tax impact of one-time transition tax on unrepatriated earnings of foreign subsidiaries under the Act of $52.9 million, which is partially offset by the utilization of foreign tax credits of $22.6 million; (iii) tax benefit of $53.0 million as a result of the revaluation of our net deferred tax liabilities; and (iv) tax benefit due to release of $22.8 million of foreign tax credit valuation allowances.

Our effective income tax rate for fiscal year 2017 was (22.6)%representing the income tax expense rate on a pre-tax net loss for the fiscal year, which was reduced by $37.0 million of tax expense for an increase in valuation allowance.

A portion of our aircraft fleet is owned directly or indirectly by our wholly owned Cayman Island subsidiaries. Our foreign operations combined with our leasing structure provided a material benefit to the effective tax rates for fiscal years 2018, 2017 and 2016. In fiscal year 2017, our unfavorable permanent differences, such as valuation allowances and non-tax deductible goodwill write-off had the effect of increasing our income tax expense and reducing our effective tax rate applied to pre-tax losses. Also, our effective tax rates for fiscal years 2018, 2017 and 2016 benefited from the permanent investment outside the U.S. of foreign earnings, upon which no U.S. tax had been provided until the one-time transition tax on unrepatriated earnings of foreign subsidiaries under the Act.

In fiscal year 2017, our effective tax rate was impacted by valuation allowances of $37.0 million and a change in the mix of geographic earnings in which we experienced U.S. losses offset by taxes in jurisdictions taxed on a deemed profit basis. The current effective tax rate was impacted by the tax effect of the $8.7 million goodwill impairment discussed in Note 1.

In August 2008, certain of our existing and newly created subsidiaries completed intercompany leasing transactions involving eleven aircraft. The tax benefit of this transaction is being recognized over the remaining useful life of the assets, which is approximately 13 years. During each of the fiscal years 2017 and 2016, this transaction resulted in a $2.4 million and $2.8 million reduction in our consolidated provision for income taxes, respectively. This transaction resulted in no impact on our consolidated provision for income taxes during fiscal year 2018.

Our operations are subject to the jurisdiction of multiple tax authorities, which impose various types of taxes on us, including income, value added, sales and payroll taxes. Determination of taxes owed in any jurisdiction requires the interpretation of related tax laws, regulations, judicial decisions and administrative interpretations of the local tax authority. As a result, we are subject to tax assessments in such jurisdictions including the re-determination of taxable amounts by tax authorities that may not agree with our interpretations and positions taken. The following table summarizes the years open by jurisdiction as of March 31, 2018:

Jurisdiction	Years Open
U.S.	Fiscal year 2014 to present
U.K.	Fiscal year 2017 to present
Nigeria	Fiscal year 2009 to present
Trinidad	Fiscal year 2005 to present
Australia	Fiscal year 2014 to present
Norway	Fiscal year 2014 to present

The effects of a tax position are recognized in the period in which we determine that it is more-likely-than-not (defined as a more than 50% likelihood) that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. A tax position that meets the more-likely-than-not recognition threshold is measured as the largest amount of tax benefit that is greater than 50% likely of being recognized upon ultimate settlement.

We have analyzed filing positions in the federal, state and foreign jurisdictions where we are required to file income tax returns for all open tax years. We believe that the settlement of any tax contingencies would not have a significant impact on our consolidated financial position, results of operations or liquidity. In fiscal years 2018, 2017 and 2016, we had a net provision of $5.4 million, $0.2 million and $0.4 million, respectively, of reserves for tax contingencies primarily related to non-U.S. income tax on foreign leasing operations. Our policy is to accrue interest and penalties associated with uncertain tax positions in our provision for income taxes. In fiscal years 2018, 2017 and 2016, $0.1 million, $0.2 million and $0.3 million, respectively, in interest and penalties were accrued in connection with uncertain tax positions.

As of March 31, 2018 and 2017, we had $6.7 million and $1.3 million, respectively, of unrecognized tax benefits, all of which would have an impact on our effective tax rate, if recognized.

The activity associated with our unrecognized tax benefit during fiscal years 2018 and 2017 is as follows (in thousands):

	Fiscal Year Ended March 31,
	2018			2017
Unrecognized tax benefits – beginning of fiscal year	$	1,332		$	1,093
Increases for tax positions taken in prior years	7,784			1,059
Decreases for tax positions taken in prior years	(2,434		)	(818		)
Decrease related to statute of limitation expirations	—			(2		)
Unrecognized tax benefits – end of fiscal year	$	6,682		$	1,332

As of March 31, 2018, we have aggregated approximately $517.9 million in unremitted foreign earnings reinvested abroad. Pursuant to the Act, these earnings were subject to the mandatory one-time transition tax and eligible to be repatriated to the U.S. without additional U.S. tax. Although these foreign earnings have been deemed to be repatriated from a U.S. federal income tax perspective, we have not yet completed our assessment of the U.S. tax reform on our plans to reinvest foreign earnings and as such have not changed our prior conclusion that the unremitted earnings are indefinitely reinvested. Accordingly, we have not provided deferred taxes on these unremitted earnings. If our expectations were to change, withholding and other applicable taxes incurred upon repatriation, if any, are not expected to have a significant impact on our results of operations.

We receive a tax benefit that is generated by certain employee stock benefit plan transactions. Under previous accounting guidance, in fiscal years 2017 and 2016, this benefit was recorded directly to additional paid-in-capital on our consolidated balance sheets and did not reduce our effective income tax rate.

Income taxes paid during fiscal years 2018, 2017 and 2016 were $26.7 million, $28.1 million and $28.0 million, respectively.

EMPLOYEE BENEFIT PLANS

EMPLOYEE BENEFIT PLANS

Defined Contribution Plans

The Bristow Group Inc. Employee Savings and Retirement Plan (the “Bristow Plan”) covers certain of our U.S. employees. Under the Bristow Plan, we match each participant’s contributions up to 3% of the employee’s compensation. In addition, under the Bristow Plan, we contribute an additional 3% of the employee’s compensation at the end of each calendar year.

Bristow Helicopters and Bristow International Aviation (Guernsey) Limited (“BIAGL”) have a defined contribution plan. This defined contribution plan replaced the defined benefit pension plans described below for future accrual.

On March 1, 2016, the defined benefit pension plan in Norway was closed and replaced with a defined contribution plan.

Our contributions to our defined contribution plans were $22.0 million, $21.8 million and $14.4 million for fiscal years 2018, 2017 and 2016, respectively.

Defined Benefit Plans

The defined benefit pension plans of Bristow Helicopters and BIAGL replaced by the defined contribution plans described above covered all full-time employees of Bristow Aviation and BIAGL employed on or before December 31, 1997. Both plans were closed to future accrual as of February 1, 2004. The defined benefits for employee members were based on the employee’s annualized average last three years’ pensionable salaries up to February 1, 2004, increasing thereafter in line with retail price inflation (prior to 2011) and consumer price inflation (from 2011 onwards), and subject to maximum increases of 5% per year over the period to retirement. Any valuation deficits are funded by contributions by Bristow Helicopters and BIAGL. Plan assets are held in separate funds administered by the plans’ trustee (the “Plan Trustee”), which are primarily invested in equities and debt securities. For members of the two closed defined benefit pension plans, since January 2005, Bristow Helicopters contributes a maximum of 7% of a participant’s non-variable salary, and since April 2006, the maximum employer contribution into the plan has been 7.35% for pilots. Each member is required to contribute a minimum of 5% of non-variable salary for Bristow Helicopters to match the contribution. In addition, there are three defined contribution plans for staff who were not members of the original defined benefit plans, two of which are closed to new members.

The following tables provide a rollforward of the projected benefit obligation and the fair value of plan assets, set forth the defined benefit retirement plans’ funded status and provide detail of the components of net periodic pension cost calculated for the U.K. pension plans. The measurement date adopted is March 31. For the purposes of amortizing gains and losses, the 10% corridor approach has been adopted and assets are taken at fair market value. Any such gains or losses are amortized over the average remaining life expectancy of the plan members.

_______________

⁽¹⁾  Bristow Norway had a final salary defined benefit plan prior to its closing on March 1, 2016, which led to a curtailment and settlement of the projected benefit obligations.

The amount in accumulated other comprehensive loss as of March 31, 2018 expected to be recognized as a component of net periodic pension cost in fiscal year 2019 is $6.5 million, net of tax, and represents amortization of the net actuarial losses.

Actuarial assumptions used to develop the components of the U.K. plans were as follows:    

	Fiscal Year Ended March 31,
	2018		2017		2016
Discount rate	2.40	%	3.30	%	3.30	%
Expected long-term rate of return on assets	4.41	%	5.30	%	5.40	%
Pension increase rate	3.00	%	2.80	%	2.80	%

Actuarial assumptions used to develop the components of the Norway plan were as follows:

	Fiscal Year Ended March 31, 2016
Discount rate	2.50	%
Rate of compensation increase	3.50	%
Social Security increase amount	3.25	%
Expected return on plan assets	1.50	%
Pension increase rate	—	%

We utilize a British pound sterling denominated AA corporate bond index as a basis for determining the discount rate for our U.K. plans. The expected rate of return assumptions have been determined following consultation with our actuarial advisors. In the case of bond investments, the rates assumed have been directly based on market redemption yields at the measurement date, and those on other asset classes represent forward-looking rates that have typically been based on other independent research by investment specialists.

Under U.K. and Guernsey legislation, it is the Plan Trustee who is responsible for the investment strategy of the plans, although day-to-day management of the assets is delegated to a team of regulated investment fund managers. The Plan Trustee of the Bristow Staff Pension Scheme (the “Scheme”) has the following three stated primary objectives when determining investment strategy:

(i) “funding objective” - to ensure that the Scheme is fully funded using assumptions that contain a modest margin for prudence. Where an actuarial valuation reveals a deficit, a recovery plan will be put in place which will take into account the financial covenant to the employer;

(ii) “stability objective” - to have due regard to the likely level and volatility of required contributions when setting the Scheme’s investment strategy; and

(iii) “security objective” - to ensure that the solvency position of the Scheme (as assessed on a gilt basis) is expected to improve. The Plan Trustee will take into account the strength of the employer’s covenant when determining the expected improvement in the solvency position of the Scheme.

The types of investments are held, and the relative allocation of assets to investments is selected, in light of the liability profile of the Scheme, its cash flow requirements, the funding level and the Plan Trustee’s stated objectives. In addition, in order to avoid an undue concentration of risk, assets are diversified within and across asset classes.

In determining the overall investment strategy for the plans, the Plan Trustee undertakes regular asset and liability modeling (the “ALM”) with the assistance of their U.K. actuary. The ALM looks at a number of different investment scenarios and projects both a range and a best estimate of likely return from each one. Based on these analyses, and following consultation with us, the Trustee determines the benchmark allocation for the plans’ assets.

The market value of the plan’s assets as of March 31, 2018 and 2017 was allocated between asset classes as follows. Details of target allocation percentages under the Plan Trustee’s investment strategies as of the same dates are also included.

Corporate debt securities	—		71,276		—		71,276
Total investments	$	70,650	$	384,889	$	—	$	455,539

The investments’ fair value measurement level within the fair value hierarchy is classified in its entirety based on the lowest level of input that is significant to the measurement. The fair value of assets using Level 2 inputs is determined based on the fair value of the underlying investment using quoted prices in active markets or other significant inputs that are deemed observable.

Estimated future benefit payments over each of the next five fiscal years from March 31, 2018 and in aggregate for the following five fiscal years after fiscal year 2023 are as follows (in thousands):

Projected Benefit Payments by the Plans for Fiscal Years Ending March 31,	Payments
2019	$	23,146
2020	23,567
2021	24,268
2022	24,830
2023	25,531
Aggregate 2024 - 2028	133,687

We expect to fund these payments with our cash contributions to the plans, plan assets and earnings on plan assets. The current estimates of our cash contributions for our pension plans required for fiscal year 2019 are expected to be $18.0 million.

Incentive Compensation

Incentive and Stock Option Plans — Stock–based awards are currently made under the Bristow Group Inc. 2007 Long-Term Incentive Plan (the “2007 Plan”). As of March 31, 2018, a maximum of 10,646,729 shares of common stock are reserved, including 2,508,134 shares available for incentive awards under the 2007 Plan. 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 our common stock) or performance awards, or any combination thereof, and may be made to outside directors, employees or consultants.

In addition, we have the following incentive and stock plans which have awards outstanding as of March 31, 2018, but under which we no longer make grants:

• The 2004 Stock Incentive Plan (the “2004 Plan”), which provided for awards to officers and key employees in the form of stock options, stock appreciation rights, restricted stock, other stock-based awards or any combination thereof. Options become exercisable at such time or times as determined at the date of grant and expire no more than 10 years after the date of grant.

• The 2003 Non-qualified Stock Option Plan for Non-employee Directors (the “2003 Director Plan”), which provided for a maximum of 250,000 shares of our common stock to be issued pursuant to such plan. As of the date of each annual meeting, each non-employee director who met certain attendance criteria was automatically granted an option to purchase 5,000 shares of our common stock. The exercise price of the options granted was equal to the fair market value of our common stock on the date of grant, and the options were exercisable not earlier than six months after the date of grant and expire no more than ten years after the date of grant.

In June 2017, June 2016 and June 2015, the Compensation Committee of our board of directors authorized the grant of stock options, time vested restricted stock and long-term performance cash awards to participating employees. Each of the stock options has a ten-year term and has an exercise price equal to the fair market value (as defined in the 2007 Plan) of our common stock on the grant date. The options will vest in annual installments of one-third each, beginning on the first anniversary of the grant date. Restricted stock grants vest at the end of three years. Performance cash awards granted in June 2017 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. Performance cash awards granted in June 2015 and June 2016 allow the recipient to receive from 0 to 200% of the target amount at the end of three years depending on how our total shareholder return ranks among a peer group over the performance period. The value of the performance cash awards is calculated on a quarterly basis by comparing the performance of our common stock, including any dividends paid since the award date, against the peer group and has a maximum potential payout of $15.7 million, $7.9 million and $7.4 million for the June 2017, June 2016 and June 2015 awards, respectively. The total value of the awards is recognized as compensation expense over a three-year vesting period with the recognition amount being adjusted quarterly. Compensation expense related to the performance cash awards during fiscal years 2018, 2017 and 2016 was $1.5 million, $7.0 million and $1.4 million, respectively. Performance cash compensation expense has been allocated to our various regions.

Total share-based compensation expense, which includes stock options and restricted stock, was $10.4 million, $12.4 million and $21.2 million for fiscal years 2018, 2017 and 2016, respectively. Stock-based compensation expense is included in general and administrative expense in the consolidated statements of operations and has been allocated to our various regions.

On May 23, 2016, our board of directors approved an amendment and restatement of the 2007 Plan, which was approved by our stockholders on August 3, 2016, that effected each of the following changes: (i) reserved an additional 5,250,000 “shares” (or 2,625,000 full value shares) that, when combined with “shares” remaining available for issuance under the 2007 plan resulted in a total of approximately 6,400,000 “shares” (or approximately 3,200,000 full value shares) available for issuance under the amended and restated 2007 plan, with each option and stock appreciation right granted under the amended and restated 2007 plan counting as one “shares” against such total and with each incentive award that may be settled in common stock counting as two “shares” (or one full value share) against such total; (ii) increased the maximum share-based employee award under the amended and restated 2007 plan from 500,000 full value shares to 1,000,000 full value shares; (iii) set the maximum aggregate compensation and incentive awards that may be provided by the Company in any calendar year to any non-employee member of the board of directors at $1,125,000; and (iv) made other administrative and updating changes.

A summary of our stock option activity for fiscal year 2018 is presented below:

	Weighted Average Exercise Prices		Number of Shares		Weighted Average Remaining Contractual Life	Aggregate Intrinsic Value
						(in thousands)
Outstanding at March 31, 2017	$	42.78	2,843,608
Granted	7.03		1,256,043
Expired or forfeited	44.95		(525,873	)
Outstanding at March 31, 2018	29.90		3,573,778		6.38	$	7,031
Exercisable at March 31, 2018	46.49		1,812,825		4.00	$	—

Stock options granted to employees under the 2004 and 2007 Plans vest ratably over three years on each anniversary from the date of grant and expire 10 years from the date of grant.

We use a Black-Scholes option pricing model to estimate the fair value of share-based awards. The Black-Scholes option pricing model incorporates various assumptions, including the risk-free interest rate, volatility, dividend yield and the expected term of the options.

The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for a period equal to the expected term of the option. Expected volatilities are based on the historical volatility of shares of our common stock, which has not been adjusted for any expectation of future volatility given uncertainty related to the future performance of our common stock at this time. We also use historical data to estimate the expected term of the options within the option pricing model and groups of employees that have similar historical exercise behavior are considered separately for valuation purposes. The expected term of the options represents the period of time that the options granted are expected to be outstanding. Additionally, we record forfeitures based on actual forfeitures.

The following table shows the assumptions we used to compute the stock-based compensation expense for stock option grants issued during fiscal years 2018, 2017 and 2016.    

	Fiscal Year Ended March 31,
	2018			2017			2016
Risk free interest rate	1.78		%	1.07		%	1.62		%
Expected life (years)	5			5			5
Volatility	56.1		%	46.8		%	28.1		%
Dividend yield	3.98		%	2.74		%	3.14		%
Weighted average grant-date fair value of options granted	$	2.53		$	2.16		$	10.71

Unrecognized stock-based compensation expense related to nonvested stock options was approximately $2.9 million as of March 31, 2018, relating to a total of 1,760,953 unvested stock options. We recognize compensation expense on a straight-line basis over the requisite service period for the entire award. We expect to recognize this stock-based compensation expense over a weighted average period of approximately 1.8 years. The total fair value of options vested during fiscal years 2018, 2017 and 2016 was approximately $4.7 million, $7.8 million and $7.4 million, respectively.

There were no stock options exercised during fiscal years 2018, 2017 and 2016. Therefore, the total intrinsic value, determined as of the date of exercise, total amount of cash we received from option exercises and total tax benefit attributable to options exercised were all zero for fiscal years 2018, 2017 and 2016.

We have restricted stock awards that cliff vest on the third anniversary from the date of grant provided the grantee is still employed by the Company, subject to our retirement policy. Restricted stock granted to non-employee directors under the 2003 Director Plan vest after six months.

We record compensation expense for restricted stock awards based on an estimate of the service period related to the awards, which is tied to the future performance of our stock over certain time periods under the terms of the award agreements. The estimated service period is reassessed quarterly. Changes in this estimate may cause the timing of expense recognized in future periods to accelerate. Compensation expense related to awards of restricted stock for fiscal years 2018, 2017 and 2016 was $6.7 million, $8.0 million and $12.9 million, respectively.

The following is a summary of non-vested restricted stock as of March 31, 2018 and 2017 and changes during fiscal year 2018:    

	Units		Weighted Average Grant Date Fair Value per Unit
Non-vested as of March 31, 2017	739,493		$	26.97
Granted	622,652		7.35
Forfeited	(72,075	)	14.78
Vested	(391,901	)	28.48
Non-vested as of March 31, 2018	898,169		13.69

Unrecognized stock-based compensation expense related to non-vested restricted stock was approximately $6.4 million as of March 31, 2018, relating to a total of 898,169 unvested restricted stock. We expect to recognize this stock-based compensation expense over a weighted average period of approximately 1.6 years.

During June 2017, we awarded certain members of management phantom restricted stock, which will be paid out in cash after three years. Additionally, during March 2018, we awarded 22,034 shares of restricted stock to a consultant, which will be paid out in shares after six months. We account for these awards as liability awards. As of March 31, 2018, we had $0.1 million in other accrued liabilities and $1.0 million in other liabilities and deferred credits on our consolidated balance sheet and recognized $1.1 million in general and administrative expense on our consolidated statement of operations for fiscal year 2018 related to these awards.

The Annual Incentive Compensation Plan provides for an annual award of cash bonuses to key employees based primarily on pre-established objective measures of performance. The bonuses related to this plan were $10.1 million and $5.0 million for fiscal years 2018 and 2017, respectively. There were no bonuses awarded related to this plan during fiscal year 2016.

Additionally, we have a non-qualified deferred compensation plan for our senior executives. Under the terms of the plan, participants can elect to defer a portion of their compensation for distribution at a later date. In addition, we have the discretion to make annual tax deferred contributions to the plan on the participants’ behalf. We contributed $0.1 million, $0.6 million and $1.3 million to this plan in each of fiscal years 2018, 2017 and 2016, respectively. The assets of the plan are held in a rabbi trust and are subject to our general creditors. As of March 31, 2018, the amount held in trust was $2.3 million.

Separation Agreements — In March 2015, May 2016 and February 2018, we offered voluntary separation programs (“VSPs”) to certain employees as part of our ongoing efforts to improve efficiencies and reduce costs. Additionally, beginning in March 2015, we initiated involuntary separation programs (“ISPs”) in certain regions. The expense related to the VSPs and ISPs for the fiscal years 2018, 2017 and 2016 is as follows (in thousands):

	Fiscal Year Ended March 31,
	2018		2017		2016

STOCKHOLDERS’ INVESTMENT, EARNINGS PER SHARE AND ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS)

Stockholders’ Investment

Common Stock — The total number of authorized shares of our common stock reserved as of March 31, 2018 was 6,980,081. These shares are reserved in connection with our stock-based compensation plans.

The following is a summary of changes in outstanding shares of common stock for the years ended March 31, 2018 and 2017:

	Shares	Weighted Average Price Per Share
Outstanding as of March 31, 2016	34,976,743
Issuance of restricted stock	237,248	$	17.41
Outstanding as of March 31, 2017	35,213,991
Issuance of restricted stock	312,634	$	11.27
Outstanding as of March 31, 2018	35,526,625

Restrictions on Foreign Ownership of Common Stock — Under the Federal Aviation Act of 1958, as amended (the “Federal Aviation Act”), it is unlawful to operate certain aircraft for hire within the U.S. unless such aircraft are registered with the Federal Aviation Administration (the “FAA”) and the FAA has issued an operating certificate to the operator. As a general rule, aircraft may be registered under the Federal Aviation Act only if the aircraft are owned or controlled by one or more citizens of the U.S. and an operating certificate may be granted only to a citizen of the U.S. For purposes of these requirements, a corporation is deemed to be a citizen of the U.S. only if, among other things, at least 75% of its voting interests are owned or controlled by U.S. citizens. If persons other than U.S. citizens should come to own or control more than 25% of our voting interest or if any other requirements are not met, we have been advised that our aircraft may be subject to deregistration under the Federal Aviation Act, and we may lose our ability to operate within the U.S. Deregistration of our aircraft for any reason, including foreign ownership in excess of permitted levels, would have a material adverse effect on our ability to conduct certain operations within our Americas region. Therefore, our organizational documents currently provide for the automatic suspension of voting rights of shares of our common stock owned or controlled by non-U.S. citizens, and our right to redeem those shares, to the extent necessary to comply with these requirements. As of March 31, 2018, approximately 6,214,000 shares of our common stock were held by persons with foreign addresses. These shares represented approximately 17% of our total outstanding common shares as of March 31, 2018. Our foreign ownership may fluctuate on each trading day because our common stock is publicly traded.

Dividends — In August 2017, we suspended our quarterly dividend as part of a broader plan of reducing costs and improving liquidity. Prior to that, we paid quarterly dividends of $0.07 per share during the first quarter of fiscal year 2018 and each quarter of fiscal year 2017, quarterly dividends of $0.34 per share during the first, second and third quarters of fiscal year 2016 and a dividend of $0.07 per share during the fourth quarter of fiscal year 2016. For fiscal years 2018, 2017 and 2016, we paid dividends totaling $2.5 million, $9.8 million and $38.1 million, respectively, to our stockholders. The declaration of future dividends is at the discretion of our board of directors and subject to our results of operations, financial condition, cash requirements and other factors and restrictions under applicable law and our debt instruments.

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. Diluted earnings per common share excludes options to purchase shares and restricted stock awards, which were outstanding during the period but were anti-dilutive, as follows:

	Fiscal Year Ended March 31,
	2018		2017		2016
Options:
Outstanding	2,890,140		1,815,020		1,194,783
Weighted average exercise price	$	38.77	$	31.98	$	62.11
Restricted stock awards:
Outstanding	547,927		541,014		286,804
Weighted average price	$	21.00	$	26.76	$	37.27

The following table sets forth the computation of basic and diluted earnings per share:

Diluted loss per common share	$	(5.54	)	$	(4.87	)	$	(2.12	)

_____________

⁽¹⁾  Diluted earnings per common share for fiscal year 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 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 earnings per share for fiscal year 2018 as our average stock price during the year did not meet or exceed the conversion requirements.

⁽²⁾  Potentially dilutive shares issuable pursuant to our Warrant Transactions were not included in the computation of diluted income per share for fiscal year 2018, because to do so would have been anti-dilutive. For further details on the Warrant Transactions, see Note 4.

Supplemental Condensed Consolidating Financial Information [Abstract]

SUPPLEMENTAL CONDENSED CONSOLIDATING FINANCIAL INFORMATION

SUPPLEMENTAL CONDENSED CONSOLIDATING FINANCIAL INFORMATION

The Company has registered senior notes (see Note 4) that the Guarantor Subsidiaries have fully, unconditionally, jointly and severally guaranteed. The Company has also issued certain other unregistered debt securities that have been fully, unconditionally, jointly and severally guaranteed by the Guarantor Subsidiaries that also guarantee the registered senior notes. 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.

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 intercompany 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.

OPERATIONS, BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

12 Months Ended

Mar. 31, 2018

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of presentation policy

The consolidated financial statements include the accounts of Bristow Group Inc. and its consolidated entities after elimination of all significant intercompany accounts and transactions. Investments in affiliates in which we have a majority voting interest and entities that meet the criteria of Variable Interest Entities (“VIEs”) of which we are the primary beneficiary are consolidated. See discussion of VIEs in Note 2. We apply the equity method of accounting for investments in entities if we have the ability to exercise significant influence over an entity that (a) does not meet the variable interest entity criteria or (b) meets the variable interest entity criteria, but for which we are not deemed to be the primary beneficiary. We apply the cost method of accounting for investments in other entities if we do not have the ability to exercise significant influence over the unconsolidated affiliate. These investments in private companies are carried at cost and are adjusted only for capital distributions and other-than-temporary declines in value. Dividends from cost method investments are recognized in earnings from unconsolidated affiliates, net of losses, when paid.

Fiscal period policy

Our fiscal year ends March 31, and we refer to fiscal years based on the end of such period. Therefore, the fiscal year ended March 31, 2018 is referred to as fiscal year 2018.

Reclassification policy

Certain reclassifications of prior period information have been made to conform to the presentation of the current period information as a result of an adoption of a required accounting standard. In prior period financial statements, we had included employee taxes paid for withheld shares as a cash flow operating activity. During fiscal year 2018, we have reclassified employee taxes paid for withheld shares to be presented as a cash flow financing activity as a result of the adoption of new accounting standards effective April 1, 2017. These reclassifications had no effect on our consolidated statements of operations or our consolidated balance sheet as previously reported.

Use of estimates policy

The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expense during the reporting period. Actual results could differ from those estimates. Areas where accounting estimates are made by management include:

• Allowances for doubtful accounts;

• Inventory allowances;

• Property and equipment;

• Goodwill, intangible and other long-lived assets;

• Pension benefits;

• Contingent liabilities; and

• Taxes.

Cash and cah equivalents policy

Our cash equivalents include funds invested in highly-liquid debt instruments with original maturities of 90 days or less.

Accounts receivable policy

Trade and other receivables are stated at net realizable value. We grant short-term credit to our clients, primarily major integrated, national and independent oil and gas companies. We establish allowances for doubtful accounts on a case-by-case basis when a determination is made that the required payment is unlikely to occur. In establishing these allowances, we consider a number of factors, including our historical experience, change in our clients’ financial position and restrictions placed on the conversion of local currency into U.S. dollars, as well as disputes with clients regarding the application of contract provisions to our services.

Inventories policy

Inventories are stated at the lower of average cost or net realizable value and consist primarily of spare parts.

Property and equipment policy

Property and equipment are stated at cost. Property and equipment includes construction in progress, primarily consisting of progress payments on aircraft purchases and facility construction, of $67.7 million and $199.3 million as of March 31, 2018 and 2017, respectively. Interest costs applicable to the construction of qualifying assets are capitalized as a component of the cost of such assets.

Depreciation and amortization are provided using the straight-line method over the estimated useful lives of the assets. The estimated useful lives of aircraft generally range from 5 to 15 years, and the residual value used in calculating depreciation of aircraft generally ranges from 30% to 50% of cost. The estimated useful lives for buildings on owned properties range from 15 to 30 years. Other depreciable assets are depreciated over estimated useful lives ranging from 3 to 15 years, except for leasehold improvements which are depreciated over the lesser of the useful life of the improvement or the lease term (including any period where we have options to renew if it is probable that we will renew the lease). The cost and related accumulated depreciation of assets sold or otherwise disposed of are removed from the accounts and the resulting gains or losses are included in gain (loss) on disposal of assets.

We capitalize betterments and improvements to our aircraft and depreciate such costs over the remaining useful lives of the aircraft. Betterments and improvements increase the life or utility of an aircraft.

Goodwill policy

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.

Other intangible assets policy

Intangible assets with finite useful lives are amortized over their respective estimated useful lives to their estimated residual values.

Contingent liabilities policy

We establish reserves for estimated loss contingencies when we believe a loss is probable and the amount of the loss can be reasonably estimated. Our contingent liability reserves relate primarily to potential tax assessments, litigation, personal injury claims and environmental liabilities. Results for each reporting period include revisions to contingent liability reserves resulting from different facts or information which becomes known or circumstances which change and affect our previous assumptions with respect to the likelihood or amount of loss. Such revisions are based on information which becomes known or circumstances that change after the reporting date for the previous period through the reporting date of the current period. Reserves for contingent liabilities are based upon our assumptions and estimates regarding the probable outcome of the matter. Should the outcome differ from our assumptions and estimates or other events result in a material adjustment to the accrued estimated reserves, revisions to the estimated reserves for contingent liabilities would be required to be recognized. Legal costs are expensed as incurred.

Proceeds from casualty insurance settlements in excess of the carrying value of damaged assets are recognized in gain (loss) on disposal of assets when we have received proof of loss documentation or are otherwise assured of collection of these amounts.

Impairment of 50% or less owned investments policy

We perform regular reviews of each investee’s financial condition, the business outlook for its products and services, and its present and projected results and cash flows. When an investee has experienced consistent declines in financial performance or difficulties raising capital to continue operations, and when we expect the decline to be other-than-temporary, the investment is written down to fair value. Actual results may vary from estimates due to the uncertainty regarding the projected financial performance of investees, the severity and expected duration of declines in value, and the available liquidity in the capital markets to support the continuing operations of the investees in which we have investments.

Impairment of long-lived assets policy

Long-lived assets, such as property and equipment, and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If the carrying amount of an asset group to be held and used exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset group exceeds the fair value of the asset group.

Revenue recognition policy

In general, we recognize revenue when it is both realized or realizable and earned. We consider revenue to be realized or realizable and earned when the following conditions exist: there is persuasive evidence of an arrangement (generally a client contract exists); the services or products have been performed or delivered to the client; the sales price is fixed or determinable; and collection has occurred or is probable.

Revenue from helicopter services, including SAR services, is recognized based on contractual rates as the related services are performed. The charges under these contracts are generally based on a two-tier rate structure consisting of a daily or monthly fixed fee plus additional fees for each hour flown. These contracts are for varying periods and generally permit the client to cancel the contract before the end of the term. We also provide services to clients on an “ad hoc” basis, which usually entails a shorter contract notice period and duration. The charges for ad hoc services are based on an hourly rate or a daily or monthly fixed fee plus additional fees for each hour flown. 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 rate increases when the criteria outlined above have been met. This generally includes written recognition from the clients that they are in agreement with the amount of the rate escalation. Cost reimbursements from clients are recorded as reimbursable revenue with the related reimbursed costs recorded as reimbursable expense on our consolidated statements of operations.

Eastern Airways and Airnorth primarily earn revenue through charter and scheduled airline services and provision of airport services (Eastern Airways only). Both chartered and scheduled airline service revenue is recognized net of passenger taxes and discounts. Revenue is recognized 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. Airport services revenue is recognized when earned.

Prior to the sale on November 1, 2017, Bristow Academy, our helicopter training unit, primarily earned revenue from military training, flight training provided to individual students and ground school courses. We recognized revenue from these sources using the same revenue recognition principles described above as services were provided. We consider revenue to be realized or realizable and earned when the following conditions exist: there is persuasive evidence of an arrangement (generally a contract exists); the services have been performed or delivered to the client or student; the sales price is fixed and determinable; and collection has occurred or is probable.

Maintenance and repairs policy

We generally charge maintenance and repair costs, including major aircraft component overhaul costs, to earnings as the costs are incurred. However, certain major aircraft components, such as engines and transmissions, are maintained by third-party vendors under contractual agreements also referred to as power-by-the hour maintenance agreements. Under these agreements, we are charged an agreed amount per hour of flying time related to maintenance, repair and overhaul of the parts and components covered. The costs charged under these contractual agreements are recognized in the period in which the flight hours occur. To the extent that we have not yet been billed for costs incurred under these arrangements, these costs are included in accrued maintenance and repairs on our consolidated balance sheets. From time to time, we receive credits from our original equipment manufacturers as settlement for additional labor and maintenance expense costs incurred for aircraft performance issues. We record these credits as a reduction in maintenance expense when the credits are utilized in lieu of cash payments for purchases or services. The cost of certain major overhauls on owned fixed-wing aircraft operated by Eastern Airways and Airnorth are capitalized when incurred and depreciated over the period until the next expected major overhaul. The cost of major overhauls on leased fixed-wing aircraft operated by Eastern Airways and Airnorth are charged to maintenance and repair costs when incurred.

Taxes policy

We follow the liability method of accounting for income taxes. Under this method, deferred income tax assets and liabilities are determined based upon temporary differences between the carrying amount and tax basis of our assets and liabilities and measured using enacted tax rates and laws that will be in effect when the differences are expected to reverse. The effect on deferred income tax assets and liabilities of a change in the tax rates is recognized in income in the period in which the change occurs. We record a valuation reserve when we believe that it is more likely than not that any deferred income tax asset created will not be realized.

In assessing the realizability of deferred income tax assets, management considers whether it is more-likely-than-not that some portion or all of the deferred income tax assets will not be realized. The ultimate realization of deferred income tax assets is dependent upon the generation of future taxable income during the periods in which such temporary differences become deductible.

Tax uncertainties policy

We recognize tax benefits attributable to uncertain tax positions when it is more-likely-than-not that a tax position will be sustained upon examination by the authorities. The benefit from a position that has surpassed the more-likely-than-not threshold is the largest amount of benefit that is more than 50% likely to be realized upon settlement. We recognize interest and penalties accrued related to unrecognized tax benefits as a component of benefit (provision) for income taxes in our statement of operations.

Foreign currency policy

In preparing our financial statements, we must convert all non-U.S. dollar currencies to U.S. dollars. Balance sheet information is presented based on the exchange rate as of the balance sheet date, and statement of operations information is presented based on the average exchange rate for the period. The various components of stockholders’ investment are presented at their historical average exchange rates. The resulting difference after applying the different exchange rates is the currency translation adjustment, which is reported in stockholders’ investment as accumulated other comprehensive gains or losses. Foreign currency transaction gains and losses are recorded in other income (expense), net in our statement of operations and result from the effect of changes in exchange rates on transactions denominated in currencies other than a company’s functional currency, including transactions between consolidated companies. An exception is made where an intercompany loan or advance is deemed to be of a long-term investment nature, in which instance foreign currency transaction gains or losses are included as currency translation adjustments and are reported in stockholders’ investment as accumulated other comprehensive gains or losses. Changes in exchange rates could cause significant changes in our financial position and results of operations in the future.

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 for revenue from contracts with customers. The core principle of the new standard is to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration the entity expects to be entitled to in exchange for those goods or services through a five-step model. The new standard also requires enhanced disclosures regarding the nature, amount, timing, and uncertainty of revenue and the related cash flows arising from contracts with customers. This new standard is effective for the Company beginning on April 1, 2018. The standard is required to be adopted using either the full retrospective approach, with all prior periods presented adjusted, or the modified retrospective approach, with a cumulative adjustment to retained earnings on the balance sheet. We adopted this standard on April 1, 2018, utilizing the modified retrospective method. Under the modified retrospective method of adoption, prior year reported results are not recast; however, a cumulative-effect adjustment to retained earnings at April 1, 2018 is recorded, if applicable. In addition, quarterly disclosures will include comparative information for fiscal year 2018 financial statement line items under current guidance. To the extent applicable, upon adoption, we may be required to comply with expanded disclosure requirements, including the disaggregation of revenues to depict the nature and uncertainty of types of revenues, contract assets and liabilities, performance obligations, significant judgments and estimates affecting the amount and timing of revenue recognition, and determination of transaction prices. The adoption of this guidance did not result in a cumulative-effect adjustment on April 1, 2018.

In November 2015, the FASB issued accounting guidance that changed how deferred taxes are classified on an entity’s balance sheet. The accounting guidance requires that all deferred tax assets and liabilities, along with any related valuation allowance, be classified as noncurrent on the balance sheet. The new guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016 and early adoption is permitted. The guidance may be applied either prospectively, for all deferred tax assets and liabilities, or retrospectively. If applied prospectively, entities are required to include a statement that prior periods were not retrospectively adjusted. If applied retrospectively, entities are also required to include quantitative information about the effects of the change on prior periods. We adopted this accounting guidance using the prospective adjustment option effective April 1, 2017 and prior periods were not retrospectively adjusted. As of March 31, 2017, we had $0.1 million in current deferred taxes and $0.8 million in current deferred liabilities that were reclassified to noncurrent upon adoption of this accounting guidance.

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. We have not yet adopted this standard and are currently evaluating the effect this standard will have on our financial statements.

In March 2016, the FASB issued accounting guidance related to accounting for employee share-based payments. The accounting guidance is intended to simplify several aspects of accounting for share-based payment award transactions including income tax consequences, classification of awards as either equity or liabilities and classification on the statements of cash flows. This accounting guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016 and early adoption is permitted. We adopted this standard effective April 1, 2017. The requirements related to the tax consequences of share-based payments were applied prospectively and resulted in $1.8 million recorded as an increase to the income tax provision during fiscal year 2018. We elected to record forfeitures of share-based awards based on actual forfeitures, which did not have a material effect on our financial statements. The provisions related to the presentation of excess tax benefits on the statements of cash flows did not impact our financial statements as there was no excess tax benefit recorded for the periods presented. The provisions related to presenting employee taxes paid for withheld shares as a cash flow financing activity required us to revise our prior period consolidated statement of cash flows by $0.8 million and $2.2 million with a decrease in net cash used in operating activities and a corresponding decrease in net cash provided by financing activities for fiscal years 2017 and 2016, respectively. None of the other provisions of the pronouncement had a material effect 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 assets 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 have not yet adopted this accounting guidance and are currently evaluating the effect this accounting guidance will have on our financial statements.

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 have not yet adopted this accounting guidance.

In March 2017, the FASB issued accounting guidance related to the presentation of net periodic pension cost and net periodic postretirement 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 postretirement 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 postretirement benefit in assets. We have not yet adopted this accounting guidance and are currently evaluating the effect this accounting guidance will have on our financial statements.

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 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 not yet adopted this accounting guidance and are currently evaluating the effect this accounting guidance will have on our financial statements.

In August 2017, the FASB issued new accounting guidance on derivatives and hedging, which amends and simplifies existing guidance in order to allow companies to more accurately present the economic effects of risk management activities in the financial statements. The two primary benefits resulting from these changes include the removal of the requirement to separately measure and report ineffectiveness and the ability to perform ongoing effectiveness assessments on a qualitative basis. This accounting guidance is effective for public business entities for fiscal years, and interim periods within those years, beginning after December 15, 2018, with earlier adoption permitted. We adopted this accounting guidance in fiscal year 2018. Since there were no active hedge accounting relationships as of the adoption date, there were no adjusting entries required to adjust on a modified retrospective basis.

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 March 2018, the FASB issued new accounting guidance to expand income tax accounting and disclosure guidance on accounting for the income tax effects of tax legislation commonly known as the Tax Cuts and Jobs Act (the “Act”) and among other things allows for a measurement period not to exceed one year for companies to finalize the provisional amounts recorded. We adopted this accounting guidance in fiscal year 2018. See Note 8 for further details.

Variable Interest Entities and Other Investments in Significant Affiliates [Abstract]

Variable interest entity policy

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.

Fair Value Disclosures [Abstract]

Fair value of financial instruments policy

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.

DERIVATIVE FINANCIAL INSTRUMENTS (Policies)

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives Policy

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, we entered into foreign currency put option contracts of £5 million per month through November 2018 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.

EMPLOYEE BENEFIT PLANS (Policies)

Retirement Benefits [Abstract]

Pension and other postretirement plans, policy

We utilize a British pound sterling denominated AA corporate bond index as a basis for determining the discount rate for our U.K. plans. The expected rate of return assumptions have been determined following consultation with our actuarial advisors. In the case of bond investments, the rates assumed have been directly based on market redemption yields at the measurement date, and those on other asset classes represent forward-looking rates that have typically been based on other independent research by investment specialists.

Under U.K. and Guernsey legislation, it is the Plan Trustee who is responsible for the investment strategy of the plans, although day-to-day management of the assets is delegated to a team of regulated investment fund managers. The Plan Trustee of the Bristow Staff Pension Scheme (the “Scheme”) has the following three stated primary objectives when determining investment strategy:

(i) “funding objective” - to ensure that the Scheme is fully funded using assumptions that contain a modest margin for prudence. Where an actuarial valuation reveals a deficit, a recovery plan will be put in place which will take into account the financial covenant to the employer;

(ii) “stability objective” - to have due regard to the likely level and volatility of required contributions when setting the Scheme’s investment strategy; and

(iii) “security objective” - to ensure that the solvency position of the Scheme (as assessed on a gilt basis) is expected to improve. The Plan Trustee will take into account the strength of the employer’s covenant when determining the expected improvement in the solvency position of the Scheme.

The types of investments are held, and the relative allocation of assets to investments is selected, in light of the liability profile of the Scheme, its cash flow requirements, the funding level and the Plan Trustee’s stated objectives. In addition, in order to avoid an undue concentration of risk, assets are diversified within and across asset classes.

In determining the overall investment strategy for the plans, the Plan Trustee undertakes regular asset and liability modeling (the “ALM”) with the assistance of their U.K. actuary. The ALM looks at a number of different investment scenarios and projects both a range and a best estimate of likely return from each one. Based on these analyses, and following consultation with us, the Trustee determines the benchmark allocation for the plans’ assets.

Share-based compensation, option and incentive plans policy

We use a Black-Scholes option pricing model to estimate the fair value of share-based awards. The Black-Scholes option pricing model incorporates various assumptions, including the risk-free interest rate, volatility, dividend yield and the expected term of the options.

The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for a period equal to the expected term of the option. Expected volatilities are based on the historical volatility of shares of our common stock, which has not been adjusted for any expectation of future volatility given uncertainty related to the future performance of our common stock at this time. We also use historical data to estimate the expected term of the options within the option pricing model and groups of employees that have similar historical exercise behavior are considered separately for valuation purposes. The expected term of the options represents the period of time that the options granted are expected to be outstanding. Additionally, we record forfeitures based on actual forfeitures.

Schedule of immaterial corrections to prior period financial information

The consolidated balance sheet and consolidated statements of changes in stockholders’ investment and redeemable noncontrolling interest reflect immaterial adjustments to the historical balances in retained earnings and accrued wages, benefits and related taxes for the years ended March 31, 2016, 2017 and 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 for March 31, 2015, 2016, 2017 and 2018 of $4.9 million. Retained earnings as reported was $1,284,442,000 and $1,172,273,000 for March 31, 2015 and 2016, respectively, compared to as adjusted of $1,279,493,000 and $1,167,324,000 for March 31, 2015 and 2016, respectively, after the correction.

Diluted loss per common share	$	(5.54	)	$	(4.87	)	$	(2.12	)

_____________

⁽¹⁾  Diluted earnings per common share for fiscal year 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 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 earnings per share for fiscal year 2018 as our average stock price during the year did not meet or exceed the conversion requirements.

⁽²⁾  Potentially dilutive shares issuable pursuant to our Warrant Transactions were not included in the computation of diluted income per share for fiscal year 2018, because to do so would have been anti-dilutive. For further details on the Warrant Transactions, see Note 4.

Condensed Balance Sheet

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.

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 intercompany 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.
