Other income (expense), net, in our condensed consolidated statements of operations includes foreign currency transaction gainslosses of $0.4$3.0 million and $1.6$1.7 million for the three months ended December 31,June 30, 2018 and 2017, and 2016, respectively, and foreign currency transaction gains of $1.2 million and foreign currency transaction losses of $1.8 million for the nine months ended December 31, 2017 and 2016, respectively. 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.

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 the three months ended December 31,June 30, 2018 and 2017, and 2016, earnings from unconsolidated affiliates, net of losses, decreased by $0.8$2.6 million and $1.2 million, respectively, and during the nine months ended December 31, 2017 and 2016, earnings from unconsolidated affiliates, net of losses, decreased by $1.6 million and $2.5$1.1 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.

Accounts Receivable
As of June 30 and March 31, 2018, the allowance for doubtful accounts for non-affiliates was $3.2 million and $3.3 million, respectively. There were no allowances for doubtful accounts related to accounts receivable due from affiliates as of June 30 and March 31, 2018. The allowance for doubtful accounts for non-affiliates as of June 30 and March 31, 2018 primarily relates to amounts due from a customer in Nigeria for which we no longer believe collection 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 search and rescue (“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 condensed consolidated statements of operations.

Eastern Airways International Limited (“Eastern Airways”) and Capiteq Limited, operating under the name 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 of our 100% interest in Bristow Academy, Inc. (“Bristow Academy”) 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 are provided.

Accounts Receivable
As of December 31 and March 31, 2017, the allowance for doubtful accounts for non-affiliates was $3.8 million and $4.5 million, respectively. There were no allowances for doubtful accounts related to accounts receivable due from affiliates as of December 31 and March 31, 2017. The allowance for doubtful accounts for non-affiliates as of December 31, 2017 primarily relates to amounts due from clients in Nigeria for which we no longer believe collection is probable.
Inventories
As of December 31June 30 and March 31, 2017,2018, inventories were net of allowances of $22.1$24.6 million and $21.5$26.0 million, respectively. During the ninethree months ended December 31,June 30, 2017, as a result of changes in expected future utilization of aircraft within our training fleet we recorded a $1.2 million charge to impair inventory used on our training fleet, which is included in loss on impairment on our condensed consolidated statement of operations.
Prepaid Expenses and Other Current Assets
As of December 31June 30 and March 31, 2017,2018, prepaid expenses and other current assets included the short-term portion of contract acquisition and pre-operating costs totaling $10.7$10.1 million and $9.7$10.8 million, respectively, related to the SARsearch and rescue (“SAR”) contracts in the U.K. and two clientcustomer contracts in Norway, which are recoverable under the contracts and will be expensed over the terms of the contracts. For the three months ended December 31,June 30, 2018 and 2017, and 2016, we expensed $2.8$2.7 million and $2.5 million, respectively, and for the nine months ended December 31, 2017 and 2016, we expensed $8.5 million and $8.2$2.9 million, respectively, related to these contracts.
Loss on Impairment
Loss on impairment included goodwill impairment charges of $8.7 million for the three and nine months ended December 31, 2016, and impairment charges for inventory of $1.2 million and $7.6 million for the nine months ended December 31, 2017 and December 31, 2016, respectively. The goodwill impairment charges related to Eastern Airways and resulted from an overall reduction in expected operating results due to the downturn in the oil and gas market driven by reduced crude oil prices (see discussion under “Goodwill” below). The inventory impairment for the nine months ended December 31, 2017 resulted from changes in expected future utilization of aircraft within our training fleet as discussed under “Inventories” above. The inventory impairment for the nine months ended December 31, 2016 resulted from a change in estimated consumption and the continued decline in the secondary market for certain inventory related to the decision to cease operating certain older model aircraft within our fleet in fiscal year 2018.

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 $20.3$19.2 million and $19.8$19.9 million as of December 31June 30 and March 31, 2017,2018, respectively, related to our Asia Pacific reporting unit was as follows (in thousands):

December 31, 2017$(33,883) $(6,179) $(576) $(10,223) $(50,861)
We test goodwill for impairment on an annual basis as of March 31 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 December 31, 2016, we noted an overall reduction in expected operating results for Eastern Airways from the downturn in the oil and gas market driven by reduced crude oil prices and performed an interim impairment test of goodwill for Eastern Airways. Based on this factor, we concluded that the fair value of our goodwill for Eastern Airways 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 an impairment charge of $8.7 million reflected in our results for the three and nine months ended December 31, 2016.
We estimated the implied fair value of Eastern Airways 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 downturn. Operating costs were forecasted using a combination of our historical average operating costs and expected future costs, including cost reduction initiatives. Capital requirements in the discounted cash flow model were based on management’s estimates of future capital costs driven by 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 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 Eastern Airways’ estimated fair value as the average of the values calculated under the income approach and the market approach.

Includes a $6.5 million impairment of the Bristow Academy disposal group for the nine months ended December 31, 2017.
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. As of September 30, 2017, we concluded the disposal group, comprised of the Bristow Academy assets and liabilities met the held for sale criteria under accounting standards, but did not meet the requirements for classification as discontinued operations. We evaluated the carrying value of the Bristow Academy disposal group and recorded an impairment of $6.5 million during the three months ended September 30, 2017, within loss on disposal of assets on our condensed consolidated statement of operations, to record the disposal group at fair value based on the terms of the sale. During the three months ended December 31, 2017, we recorded an additional loss on disposal of $0.7 million within loss on disposal of assets on our condensed consolidated statement of operations. The Bristow Academy disposal group is included in Corporate and other in Note 9 – Segment Information.
During the three and nine months ended December 31, 2016, we recorded accelerated depreciation of $1.1 million and $9.3 million on five and 11 aircraft, respectively, as our management decided to exit these model types earlier than originally anticipated.

During fiscal year 2018, we reached agreements with original equipment manufacturers (“OEM”) to recover approximately $130.0$136.0 million related to ongoing aircraft issues, of which $125.0 million was realized during fiscal year 2018 and $11.0 million was recovered during the three months ended December 31, 2017 and resulted in an increase in cash.June 30, 2018. To reflect the amount realized from these OEM cost recoveries during the three months ended December 31, 2017,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 $12.0$16.6 million and recorded a deferred liability of $18.5$13.9 million, included in other accrued liabilities and other liabilities and deferred credits, related to a reduction in rent expense to be recorded in future periods, of which $1.1$3.5 million was recognized in December 2017.during the three months ended June 30, 2018. 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 $2.1$6.4 million during the remainder of fiscal year 2018, $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 $17.4$10.4 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 $3.5$4.4 million during the remainder of fiscal year 2018, $7.9 million during fiscal year 2019, $4.0 million during fiscal year 2020 and $2.0 million during fiscal year 2021. For certain leased aircraft, the leases expired prior to the realization of the settlements to which they were related recognized by the immediate reduction to rent expense of $12.0 million during
During the three months ended June 30, 2018, we recovered the remaining $11.0 million in OEM cost recoveries by agreeing to net certain amounts previously accrued for aircraft leases and ninecapital expenditures against those recoveries. During the three months ended June 30, 2018, we recorded a $7.6 million increase in revenue and a $1.1 million decrease in direct cost. We expect to realize the remaining $2.3 million recovery during fiscal year 2019 as follows: $1.0 million decrease in direct cost in the three months ended September 30, 2018, $1.0 million decrease in direct cost in the three months ended December 31, 2017.2018 and $0.3 million decrease in direct cost in the three months ended March 31, 2019. The increase in revenue relates to compensation for lost revenue in prior periods from the late delivery of aircraft and the decreases in direct cost over fiscal year 2019 relate to prior costs we have incurred and future costs we expect to incur.

Recent Accounting Pronouncements
We consider the applicability and impact of all accounting standard updates (“ASUs”). ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial position or results of operations.
In May 2014, the Financial Accounting Standards Board (the “FASB”) issued accounting guidance on revenue recognition replacing the existing accounting standard and industry-specific guidance for revenue recognition with a five-step model for recognizing and measuring revenue from contracts with customers. This accounting guidance requires an entityThe underlying principle of the new standard is to recognize the amount of revenue to which it expects to be entitled fordepict the transfer of promised goods or services to customers and will replace most existing revenue recognition guidance when it becomes effective.at the amount expected to be collected. This new standard is effective for annual reporting periods beginning after December 15, 2016. However, in July 2015,2017. We adopted the FASB approved the deferralstandard as of the effective date of the revenue recognition standard permitting public entities to apply the new revenue standard to annual reporting periods beginning after December 15, 2017. Early application is permitted, but not before the original effective date of December 15, 2016. 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 have not adopted this standard yet but expect to adopt the new revenue standardApril 1, 2018 using the modified retrospective transition approach. We are continuingmethod applied to evaluateopen contracts and only to the effect this accounting guidance will have on our financial statements and related disclosures and are still assessing the differences between the new revenue standard and current accounting practices.
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 effectsversion 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 millioncontracts in current deferred tax assets and $0.8 million in current deferred tax liabilities. As a result of this adoption,effect as of April 1, 20172018. Prior period amounts have not been adjusted and going forward we will classify all current deferred taxes as non-current.continue to be reflected in accordance with our historical accounting policy. There was no impact on our condensed consolidated financial statements and no cumulative effect adjustment was recognized. For further details, see Note 2.
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 $2.3 million recorded as an increase to the income tax provision during the nine months ended December 31, 2017. 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 condensed consolidated 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 employee taxes paid for withheld shares are presented as a cash flow financing activity required us to revise our prior period condensed consolidated statement of cash flows by $0.8 million as a decrease in net cash used in operating activities and a corresponding decrease in net cash provided by financing activities for the nine months ended December 31, 2016. None of the other provisions of the pronouncement had a material effect on our consolidated financial statements.
In October 2016, the FASB issued accounting guidance related to current and deferred income taxes for intra-entity transfer of assets other than inventory. This accounting guidance requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs and eliminates the exception for an intra-entity transfer of an asset other than inventory. This accounting guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and early adoption is permitted. We have not yet adopted this accounting guidance effective April 1, 2018 using the modified retrospective method, through a cumulative-effect adjustment directly to retained earnings. Upon adoption, we increased deferred tax liabilities by approximately $1.7 million and are currently evaluating the effect this accounting guidance will have on our financial statements.

recognized an offsetting decrease to retained earnings.
In January 2017, the FASB issued accounting guidance which clarifies the definition of a business with the objective of adding guidance to assist in evaluating whether transactions should be accounted for as acquisitions of assets or businesses. The amendment provides criteria for determining when a transaction involves the acquisition of a business. If substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, then the transaction does not involve the acquisition of a business. If the criteria are not met, then the amendment requires that to be considered a business, the operation must include at a minimum an input and a substantive process that together significantly contribute to the ability to create an output. The guidance may reduce the number of transactions accounted for as business acquisitions. This accounting guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and early adoption is permitted. The amendments should be applied prospectively, and no disclosures are required at the effective date. We have not yet adopted this accounting guidance and are currently evaluating the effect thiseffective April 1, 2018. This accounting guidance will havehas had no impact on our financial statements.statements since adoption as we have not entered into any transactions during this period.
In March 2017, the FASB issued accounting guidance related to the presentation of net periodic pension cost and net periodic postretirementpost-retirement benefit cost. The accounting guidance requires employers to disaggregate the service cost component from the other components of net benefit cost and disclose the amount of net benefit cost that is included in the statement of operations or capitalized in assets, by line item. The accounting guidance requires employers to report the service cost component in the same line item(s) as other compensation costs and to report other pension-related costs (which include interest costs, amortization of pension-related costs from prior periods, and the gains or losses on plan assets) separately and exclude them from the subtotal of operating income. The accounting guidance also allows only the service cost component to be eligible for capitalization when applicable. This accounting guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and early adoption is permitted as of the first interim period of an annual period for which interim or annual financial statements have not been issued. The accounting guidance requires application on a retrospective basis for the presentation of the service cost component and the other components of net periodic pension cost and net periodic postretirementpost-retirement benefit cost in the statement of operations and on a prospective basis for the capitalization of the service cost component of net periodic pension cost and net periodic postretirementpost-retirement benefit in assets.

Note 2 — REVENUE RECOGNITION
Revenue Recognition
In general, we recognize revenue when a service is provided or a good is sold to a customer and there is a contract. At contract inception, we assess the goods and services promised in our contracts with customers and identify all performance obligations for each distinct promise that transfers a good or service (or bundle of goods or services) to the customer. To identify the performance obligations, we consider all goods or services promised in the contract, whether explicitly stated or implied based on customary business practices. Revenue is recognized when control of the identified distinct goods or services have been transferred to the customer, the transaction price is determined and allocated to the performed performance obligations and we have determined that collection has occurred or is probable of occurring.
A majority of our revenue from contracts with customers is currently generated through two types of contracts: helicopter services and fixed wing services. Each contract type has a single distinct performance obligation as described below.
Helicopter servicesOur customers major integrated, national and independent offshore energy companies charter our helicopters primarily to transport personnel between onshore bases and offshore production platforms, drilling rigs and other installations. To a lesser extent, our customers also charter our helicopters to transport time-sensitive equipment to these offshore locations. The customers for SAR services include both the oil and gas industry and governmental agencies. Revenue from helicopter services is recognized when the performance obligation is satisfied over time based on contractual rates as the related services are performed.
A performance obligation arises under contracts with customers to render services and is the unit of account under the new accounting guidance for revenue. Operating revenue from our oil and gas segment is derived mainly from fixed-term contracts with our customers, a substantial portion of which is competitively bid. A small portion of our oil and gas customer revenue is derived from providing services on an "ad-hoc" basis. Our fixed-term contracts typically have original terms of one year to seven years (subject to provisions permitting early termination by our customers). We account for services rendered separately if they are distinct and the service is separately identifiable from other items provided to a customer and if a customer can benefit from the services rendered on its own or with other resources that are readily available to the customer. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. Within this contract type for helicopter services, we determined that each contract has a single distinct performance obligation. These services include a fixed monthly rate for a particular model of aircraft, and flight hour services, which represents the variable component of a typical contract with a customer. Rates for these services vary depending on the type of services provided and can be based on a per flight hour, per day, or per month basis. Variable charges within our flight services contracts are not effective until a customer-initiated flight order is received and the actual hours flown are determined; therefore, the associated flight revenue generally cannot be reasonably and reliably estimated beforehand. A contract’s standalone selling prices are determined based upon the prices that we charge for our services rendered. Revenue is recognized as performance obligations are satisfied over time, by measuring progress towards satisfying the contracted services in a manner that best depicts the transfer of services to the customer, which is generally represented by a period of 30 days or less. We typically invoice customers on a monthly basis and the term between invoicing and when the payment is due is typically between 30 and 60 days. In order to offset potential increases in operating costs, our long-term contracts may provide for periodic increases in the contractual rates charged for our services. We recognize the impact of these rates when estimable and applicable, which generally includes written acknowledgment from the customers that they are in agreement with the amount of the rate escalation. Cost reimbursements from customers are recorded as reimbursable revenue with the related reimbursed costs recorded as reimbursable expense on our condensed consolidated statements of operations.
Taxes collected from customers and remitted to governmental authorities and revenue are reported on a net basis in our financial statements. Thus, we exclude taxes imposed on the customer and collected on behalf of governmental agencies to be remitted to these agencies from the transaction price in determining the revenue related to contracts with a customer.
Fixed wing servicesEastern Airways and Airnorth provide fixed wing transportation services through regular passenger transport (scheduled airline service with individual ticket sales) and charter services. A performance obligation arises under contracts with customers to render services and is the unit of account under the new accounting guidance for revenue. Within fixed wing services, we determined that each contract has a single distinct performance obligation. Revenue is recognized over time at the earlier of the period in which the service is provided or the period in which the right to travel expires, which is determined by the terms and conditions of the ticket. Ticket sales are recorded within deferred revenue in accordance with the above policy. Both chartered and scheduled airline service revenue is recognized net of passenger taxes and discounts.

Contract Assets, Liabilities and Receivables
We generally satisfy performance of contract obligations by providing helicopter and fixed wing services to our customers in exchange for consideration. The timing of performance may differ from the timing of the customer’s payment, which results in the recognition of a contract asset or a contract liability. A contract asset exists when we have a contract with a customer for which revenue has been recognized (i.e. services have been performed), but customer payment is contingent on a future event (i.e. satisfaction of additional performance obligations). These contract assets are transferred to receivables when the right to consideration becomes unconditional. Contract liabilities relate to deferred revenue in which advance consideration is received from customers for contracts where revenue is recognized on future performance of services.
As of June 30 and March 31, 2018, receivables related to services performed under contracts with customers were $195.6 million and $176.5 million, respectively. All receivables from non-affiliates and affiliates are broken out further in our condensed consolidated balance sheets. During the three months ended June 30, 2018, we recognized $9.1 million of revenue from outstanding contract liabilities as of March 31, 2018. Contract liabilities related to services performed under contracts with customers was $13.3 million as of June 30 and March 31, 2018. Contract liabilities are primarily generated by our fixed wing services where customers pay for tickets in advance of receiving our services and advanced payments from helicopter services customers. There were no contract assets as of June 30 and March 31, 2018.
For the three months ended June 30, 2018, there was $1.0 million of revenue recognized from satisfied performance obligations related to prior periods (for example, due to changes in transaction price).

Although substantially all of our revenue is under contract, due to the nature of our business we do not have significant remaining performance obligations as our contracts typically include unilateral termination clauses that allow our customers to terminate existing contracts with a notice period of 30 to 180 days. The table above includes performance obligations up to the point where the parties can cancel existing contracts. Any applicable cancellation penalties have been excluded. As such, our actual remaining performance obligation revenue is expected to be greater than what is reflected above. In addition, the remaining performance obligation disclosure does not include expected consideration related to performance obligations of a variable nature (i.e., flight services) as they cannot be reasonably and reliably estimated.
Other Considerations and Practical Expedients
We were awarded a government contract to provide SAR services for all of the U.K., which commenced in April 2015. We previously incurred costs related to this contract that generate or enhance the resources used to fulfill the performance obligation within the contract and the costs are expected to be recoverable. These contract acquisition and pre-operating costs qualify for capitalization. We amortize these capitalized contract acquisition and pre-operating costs related to the UK SAR contract and two customer contracts in Norway. We determined that an amortization method that allocates the capitalized costs on a relative basis to the revenue recognized is a reasonable and systematic basis for the amortization of the pre-operating costs asset. For further details on the short and long-term pre-operating cost balances, see Note 1.
We incur incremental direct costs for obtaining contracts through sales commissions paid to ticket agents to sell seats on regular public transportation flights for our fixed-wing services only. We will utilize the practical expedient allowed by the FASB that permits us to expense the incremental costs of obtaining a contract when incurred, if the amortization period of the contract asset that we otherwise would have recognized is one year or less.
In addition, we have applied the tax practical expedient to exclude all taxes in the scope of the election from the transaction price and the invoice practical expedient that allows us to recognize revenue in the amount to which we have the right to invoice the customer and corresponds directly with the value to the customer of our performance completed to date.
Note 23 — VARIABLE INTEREST ENTITIES
A VIE is an entity that either (i) has insufficient equity to permit the entity to finance its activities without additional subordinated financial support or (ii) has equity investors who lack the characteristics of a controlling financial interest. A VIE is consolidated by its primary beneficiary. The primary beneficiary has both the power to direct the activities that most significantly impact the entity’s economic performance and the obligation to absorb losses or the right to receive benefits from the entity that could potentially be significant to the VIE. If we determine that we have operating power and the obligation to absorb losses or receive benefits, we consolidate the VIE as the primary beneficiary, and if not, we do not consolidate.
As of December 31, 2017June 30, 2018, we had interests in four VIEs of which we were the primary beneficiary, which are described below, and had no interests in VIEs of which we were not the primary beneficiary. See Note 32 to the fiscal year 20172018 Financial Statements for a description of other investments in significant affiliates.

Accordingly, pursuant to the terms of the Master Agreement dated December 12, 1996 among Caledonia and the Company, Caledonia does not currently satisfy the requirements to designate directors for nomination to our board of directors.
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 condensed 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 December 31, 2017June 30, 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 condensed consolidated statements of operations, with a corresponding increase in noncontrolling interest on our condensed consolidated balance sheets. Prepayments of the guaranteed return element of the call option are reflected as a reduction in noncontrolling interest on our condensed consolidated balance sheets. The other investors have an option to put their shares in Bristow Aviation to us. The put option price is calculated in the same way as the call option price except that the guaranteed rate for the period to April 2004 was 10% per annum. If the put option is exercised, any pre-payments of the call option price are set off against the put option price.

Bristow Helicopters Nigeria(Nigeria) Ltd. — Bristow Helicopters Nigeria(Nigeria) Ltd. (“BHNL”) is a joint venture in Nigeria in which Bristow Helicopters ownedowns a 48% interest, a Nigerian company owned 100% by Nigerian employees ownedowns a 50% interest and an employee trust fund ownedowns the remaining 2% interest as of December 31, 2017.June 30, 2018. BHNL provides industrial aviation services to clientscustomers in Nigeria.
In order to be able to bid competitively for our services in the Nigerian market, we were required to identify local citizens to participate in the ownership of entities domiciled in the region. However, these owners do not have extensive knowledge of the aviation industry and have historically deferred to our expertise in the overall management and day-to-day operation of BHNL (including the establishment of operating and capital budgets and strategic decisions regarding the potential expansion of BHNL’s operations). We have also historically provided subordinated financial support to BHNL and will need to continue to do so unless and until BHNL acquires sufficient equity to permit itself to finance its activities without that additional support from us. As we have the power to direct the most significant activities affecting the economic performance and ongoing success of BHNL and hold a variable interest in the entity in the form of our equity investment and working capital infusions, we consolidate BHNL as the primary beneficiary. The employee-owned Nigerian entity referenced above purchased a 19% interest in BHNL in December 2013 with proceeds from a loan received from BGI Aviation Technical Services Nigeria Limited (“BATS”). In July 2014, the employee-owned Nigerian entity purchased an additional 29% interest with proceeds from a loan received from Bristow Helicopters (International) Limited (“BHIL”). In April 2015, Bristow Helicopters purchased an additional 8% interest in BHNL and the employee-owned Nigerian entity purchased an additional 2% interest with proceeds from a loan received from BHIL. Both BATS and BHIL are wholly-owned subsidiaries of Bristow Aviation. The employee-owned Nigerian entity is also a VIE that we consolidate as the primary beneficiary and we eliminate the loans discussed above in consolidation.
BHNL is an indirect subsidiary of Bristow Aviation; therefore, financial information for this entity is included within the amounts for Bristow Aviation and its subsidiaries presented above.
Pan African Airlines Nigeria(Nigeria) Ltd. — Pan African Airlines Nigeria(Nigeria) Ltd. (“PAAN”) is a joint venture in Nigeria with local partners in which we own a 50.17% interest. PAAN provides industrial aviation services to clientscustomers in Nigeria.
The activities that most significantly impact PAAN’s economic performance relate to the day-to-day operation of PAAN, setting the operating and capital budgets and strategic decisions regarding the potential expansion of PAAN’s operations. Throughout the history of PAAN, our representation on the board and our secondment to PAAN of its managing director has enabled us to direct the key operational decisions of PAAN (without objection from the other board members). We have also historically provided subordinated financial support to PAAN. As we have the power to direct the most significant activities affecting the economic performance and ongoing success of PAAN and hold a variable interest in the form of our equity investment and working capital infusions, we consolidate PAAN as the primary beneficiary. However, as long as we own a majority interest in PAAN, the separate presentation of financial information in a tabular format for PAAN is not required.

4½% Convertible Senior Notes due 2023 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 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 were issued pursuant to an indenture dated as of June 17, 2008 (the “Base Indenture”), among the Company, the subsidiary guarantors named therein (the “Guarantors”) and U.S. Bank National Association, as trustee (the “Trustee”), as supplemented by the sixth supplemental indenture thereto dated as of December 18, 2017 (the “Supplemental Indenture” and, together with the Base Indenture, the “Indenture”) among us, the Guarantors and the Trustee.
The 4½% Convertible Senior Notes are convertible into cash, shares of our common stock or a combination of cash and shares of the 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 our senior unsecured obligations. As of December 31, 2017, the if-converted value of the 4½% Convertible Senior Notes did not exceed the principal balance.
The proceeds were used to repay $89.6 million of the $350 million term loan (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.

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 settledincreased 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 cash upon conversion (including partial cash settlement) be accounted for withfive years, subject to certain early maturity triggers related to maturity of other material debt or a liability component based on the fair valuechange of similar nonconvertible debt and an equity component based on the excesscontrol of the initial proceeds fromCompany.

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 JP Morgan 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 the 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.
Term Loan and Revolving Credit Facility — During the nine months endedDecember 31, 2017, we had borrowings of $174.8 million and made payments of $313.9 million under our $400 million revolving credit facility (the “Revolving Credit Facility”). Additionally, we paid $209.5 million to reduce our borrowings under the Term Loan. As of December 31, 2017, we had $12.4 million in letters of credit outstanding under the Revolving Credit Facility.
Term Loan Credit Facility — During the nine months ended December 31, 2017, we paid $45.9 million under our $200 million of term loan commitments (the “Term Loan Credit Facility”) and terminated the facility in October 2017.

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 shall be made in respect of an aircraft to be 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 will be 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 twelve 30-day months in respect of such term loan with a floating rate of interest based on one-month LIBOR, plus the Margin.
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 credit agreement, the borrower will guarantee certain of its direct parent’s obligations under existing aircraft operating leases up to a capped amount.
Other Debt — Other Debt as of March 31, 2017 primarily included amounts payable relating to the third year earn-out payment of $16.0 million for our investment in Cougar Helicopters Inc. (“Cougar”), which was paid in April 2017.
Note 45 — FAIR VALUE DISCLOSURES
Assets and liabilities subject to fair value measurement are categorized into one of three different levels depending on the observability of the inputs employed in the measurement, as follows:
Level 1 – observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.
Level 2 – inputs that reflect quoted prices for identical assets or liabilities in markets which are not active; quoted prices for similar assets or liabilities in active markets; inputs other than quoted prices that are observable for the asset or liability; or inputs that are derived principally from or corroborated by observable market data by correlation or other means.
Level 3 – unobservable inputs reflecting the Company’s own assumptions incorporated in valuation techniques used to determine fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available.
Non-recurring Fair Value Measurements
The majority of our non-financial assets, which include inventories, property and equipment, assets held for sale, goodwill and other intangible assets, are not required to be carried at fair value on a recurring basis. However, if certain triggering events occur such that a non-financial asset is required to be evaluated for impairment and deemed to be impaired, the impaired non-financial asset is recorded at its fair value.
We did not have any items valued at fair value on a non-recurring basis as of June 30, 2018

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 time frame of sales or disposals, the location of the spare parts to be sold and the condition of the spare parts to be sold or otherwise disposed of.
The fair value of 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. The loss for the three and nine months ended December 31,June 30, 2017 related to one and fivetwo aircraft held for sale, respectively, and the loss for the three and nine months ended December 31, 2016 related to one and 13 aircraft held for sale, respectively.

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 and the three months ended June 30, 2018, we entered into foreign currency put option contracts of £5 million per month through May 2019 to mitigate a portion of our foreign currency exposure. These derivatives were designated as cash flow hedges.
The designation of a derivative instrument as a hedge and its ability to meet relevant hedge accounting criteria determines how the change in fair value of the derivative instrument will be reflected in the consolidated financial statements. A derivative qualifies for hedge accounting if, at inception, the derivative is expected to be highly effective in offsetting the hedged item’s underlying cash flows or fair value and the documentation requirements of the accounting standard for derivative instruments and hedging activities are fulfilled at the time we enter into the derivative contract. A hedge is designated as a cash flow hedge, fair value hedge, or a net investment in foreign operations hedge based on the exposure being hedged. The asset or liability value of the derivative will change in tandem with its fair value. For derivatives designated as cash flow hedges, the changes in fair value are recorded in accumulated other comprehensive income (loss). The derivative’s gain or loss is released from accumulated other comprehensive income (loss) to match the timing of the effect on earnings of the hedged item’s underlying cash flows.
We review the effectiveness of our hedging instruments on a quarterly basis. We discontinue hedge accounting for any hedge that we no longer consider to be highly effective. Changes in fair value for derivatives not designated as hedges or those not qualifying for hedge accounting are recognized in current period earnings.
None of our derivative instruments contain credit-risk-related contingent features. Counterparties to our derivative contracts are high credit quality financial institutions.
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 June 30, 2018 (in thousands):

Employee Agreements — Approximately 53% of our employees are represented by collective bargaining agreements and/or unions with 90% 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 4%. 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.June 30, 2018 and 2017, respectively.
Separation Programs — In March 2015 and May 2016, we offered voluntary separation programs (“VSPs”) to certain employees as part of our ongoing efforts to improve efficiencies and reduce costs. Additionally, beginningBeginning in March 2015, we initiated involuntary separation programs (“ISPs”) in certain regions. Also, during June 2017, two named executive officers and the principal operating officer, and during fiscal year 2018 other employees across various regions, departed from the Company as part of an organizational restructuring.

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 December 31, 2017,June 30, 2018, we had $28.4$43.0 million of other purchase obligations representing unfilled purchase orders for aircraft parts commitments associated with upgrading facilities at our bases and non-cancelable power-by-the-hour maintenance commitments.
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 NCAA issued safety and operational directives which detail the conditions to apply for safe return to service of H225LP and AS332L2 model aircraft, where operators wish to do so. On July 5, 2018, the Accident Investigation Board Norway issued its final investigation report on the accident. The report cited a fatigue fracture within the epicyclic module of the main gear box as the cause of the accident, and issued safety recommendations in a number of areas, including gearbox design and certification requirements, failure tolerance, and continued airworthiness of the AS332L2 and the EC 225LP helicopters. We continue not to operate for commercial purposes our sole23 H225LP model aircraft, in Norway, our thirteen H225LP model aircraft in the U.K. or our six H225LP model aircraft in Australia, or for search and rescue purposes, including training and missions, any of our other four H225LP model aircraft in Norway or our other three H225LP model aircraft in Australia. Wewe are carefully evaluating next steps and demand for the H225LP model aircraft in our oil and gas and search and rescueSAR operations worldwide, with the safety of passengers and crews remaining our highest priority. During the three months ended December 31, 2017, we returned three

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 December 31, 2017June 30, 2018 to be approximately $4$5 million to $6 million.
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 68 — TAXES
We estimate the full-year effective tax rate from continuing operations and apply this rate to our year-to-date income from continuing operations. In addition, we separately calculate the tax impact of unusual or infrequent items, if any. The tax impacts of such unusual or infrequent items are treated discretely in the quarter in which they occur. During the three months ended December 31,June 30, 2018 and 2017, and 2016, our effective tax rate was 57.5%8.2% and 12.0%, and during the nine months ended December 31, 2017 and 2016, our effective tax rate was (2.7)(31.9)% and 10.2%, respectively. The effective tax rate for the three and nine months ended December 31,June 30, 2018 and 2017 and 2016 were impacted by valuation allowances against future realization of foreign tax credits and net operating losses in certain foreign jurisdictions. For the three and nine months ended December 31, 2017, our effective tax rate also includes the impact of $4.7 million of unrecognized tax benefits in certain foreign jurisdictions. Additionally, for the three and nine months ended December 31, 2017, we reported a one-time tax benefit of $14.1 million as a result of the enactment of the Tax Cuts and Jobs Act (the “Act”).
The relationship between our provision for or benefit from income taxes and our pre-tax book income can vary significantly from period to period considering, among other factors, (a) the overall level of pre-tax book income, (b) changes in the blend of income that is taxed based on gross revenues or at high effective tax rates versus pre-tax book income or at low effective tax rates and (c) our geographical blend of pre-tax book income. Consequently, our income tax expense or benefit does not change proportionally with our pre-tax book income or loss. Significant decreases in our pre-tax book income typically result in higher effective tax rates, while significant increases in pre-tax book income can lead to lower effective tax rates, subject to the other factors impacting income tax expense noted above. The increasechange in our effective tax rate excluding discrete items for the three months ended December 31, 2017June 30, 2018 compared to the three months ended December 31, 2016June 30, 2017 primarily related to an increasechanges in the blend of earnings taxed in relatively high taxed jurisdictions versus low taxed jurisdictions. Additionally, we increased our valuation allowance by $2.1$1.0 million and $3.7$11.2 million for the three months ended December 31,June 30, 2018 and 2017, and 2016, respectively, and $13.4 million and $19.3 million for the nine months ended December 31, 2017 and 2016, respectively, which also increasedimpacted our effective tax rate.
As of December 31, 2017,June 30, 2018, there were $6.2$6.7 million of unrecognized tax benefits, all of which would have an impact on our effective tax rate if recognized.
On December 22, 2017, the United States Congress enacted tax legislation commonly known as the Act.Tax Cuts and Jobs Act (the “Act”). The Act includes numerous changes in existing U.S. tax law, including a permanent reduction in the U.S. federal corporate income tax rate from 35% to 21%. The rate reduction takestook effect on January 1, 2018. Further, the Act provides for a one-time “deemed repatriation” of accumulated foreign earnings of certain foreign corporations. Under U.S. generally accepted accounting principles, our net deferred tax liabilities are required to be revalued during the period in which the new tax legislation is enacted. We have made reasonable estimates for the change in the U.S. federal corporate income tax rate and one-time “deemed repatriation” of accumulated foreign earnings. We estimateFor the year ended March 31, 2018, our provision for income tax included provisional amounts for the revaluation of U.S. net deferred tax liabilities will result in a one-time tax benefit of approximately $75.6 million offset by an estimated $61.5 million in tax expense as a resultand the impact of the “deemed repatriation” of foreign earnings. We are still analyzing certain aspectsThe provisional amounts associated with the one-time “deemed repatriation” and the re-measurement of deferred tax assets and liabilities due to the reduction in the corporate income tax rate will be adjusted over time as more guidance becomes available.
Certain provisions under the Act and refining our calculations.
Because of the complexity, we are continuingbecame applicable to evaluate certain provisions of the Act which may have an impactus on April 1, 2018 and our income taxes beginning after fiscal year 2018. tax provision for the three months ended June 30, 2018 includes the tax implications of these provisions. These provisions include Global Intangible Low-Taxed Income (“GILTI”), Base Erosion and Anti-Avoidance Tax (“BEAT”), Foreign Derived Intangible Income (“FDII”), and certain limitations on the deduction of interest expense and utilization of net operating losses.

Incentive Compensation
Stock-based awards are currently made under the Bristow Group Inc. 2007 Long-Term Incentive Plan (the “2007 Plan”). A maximum of 10,646,729 shares of common stock are reserved. Awards granted under the 2007 Plan may be in the form of stock options, stock appreciation rights, shares of restricted stock, other stock-based awards (payable in cash or common stock) or performance awards, or any combination thereof, and may be made to outside directors, employees or consultants. As of December 31, 2017June 30, 2018, 2,385,2481,679,176 shares remained available for grant under the 2007 Plan.
We have a number of other incentive and stock option plans which are described in Note 9 to our fiscal year 20172018 Financial Statements.
Total stock-based compensation expense, which includes stock options and restricted stock, totaled $2.2$1.7 million and $3.3$4.1 million for the three months ended December 31, 2017June 30, 2018 and 2016, respectively, and $8.8 million and $9.5 million for the nine months ended December 31, 2017 and 2016.2017. Stock-based compensation expense has been allocated to our various regions.
During the ninethree months ended December 31, 2017June 30, 2018, we awarded 600,618326,221 shares of restricted stock at an average grant date fair value of $7.15$12.19 per share. Also during the ninethree months ended December 31, 2017, 1,256,043June 30, 2018, 593,129 stock options were granted.

During June 2018 and 2017, we awarded certain members of management phantom restricted stock which will be paid out in cash after three years. Additionally, during fiscal year 2018, we awarded 22,034 shares of restricted stock to a consultant, which will be paid out in shares in September 2018. We account for these awards as liability awards. As of DecemberJune 30, 2018 and March 31, 2017,2018, we had $0.9$1.6 million and $1.0 million, respectively, included in other liabilities and deferred credits on our condensed consolidated balance sheet accrued for these awards. Additionally, we recognized $0.6 million and recognized $0.9$0.1 million in general and administrative expense on our condensed consolidated statement of operations during the ninethree months ended December 31,June 30, 2018 and 2017, respectively, related to these awards.

Performance cash awards granted in June 2017 and 2018 have two components. One half of each performance cash award will vest and pay out in cash three years after the date of grant at varying levels depending on our performance in Total Shareholder Return against a peer group of companies. The other half of each performance cash award will be earned based on absolute performance in respect of improved average adjusted earnings per share for the Company over the three-year performance period beginning on April 1, 2017.2017 and 2018, as applicable. Performance cash awards granted in June 2015 and June 2016 vest and pay out in cash three years after the date of grant at varying levels depending on our performance in Total Shareholder Return against a peer group of companies. These awards were designed to tie a significant portion of total compensation to performance. One of the effects of this type of compensation is that it requires liability accounting which can result in volatility in earnings. The liability recorded for these awards as of December 31June 30 and March 31, 20172018 was $6.8$5.0 million and $14.2$7.7 million, respectively, and represents an accrual based on the fair value of the awards on those dates. The decrease in the liability during the ninethree months ended December 31, 2017June 30, 2018 resulted from the payout in June 20172018 of the awards granted in June 2014,2015, partially offset by the value of the new awards granted in June 2017.2018. Any changes in fair value of the awards in future quarters will increase or decrease the liability and impact results in those periods. The effect, either positive or negative, on future period earnings can vary based on factors including changes in our stock price or the stock prices of the peer group companies, as well as changes in other market and company-specific assumptions that are factored into the calculation of fair value of the performance cash awards.
Changes in the fair values of performance cash awards reducedincreased compensation expense by $0.8$1.0 million during the three months ended December 31, 2017June 30, 2018 and increasedreduced compensation expense by $3.1 million, $0.6 million and $5.6$3.0 million during the three months ended December 31, 2016 and nine months ended December 31, 2017 and 2016, respectively.

_____________
(1) 
Diluted earnings per common share for three and nine months ended December 31, 2017June 30, 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 DecemberJune 30, 2018 and March 31, 2017,2018, 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 the three and nine months ended December 31, 2017June 30, 2018 as our average stock price during these periods did not meet or exceed the conversion requirements.
(2) 
Potentially dilutive shares issuable pursuant to our Warrant Transactionswarrant transactions entered into concurrently with the issuance of our 4½% Convertible Senior Notes (the “Warrant Transactions”) were not included in the computation of diluted income per share for the three and nine months ended December 31, 2017,June 30, 2018, because to do so would have been anti-dilutive. For further details on the Warrant Transactions, see Note 3.4 in our fiscal year 2018 Financial Statements.

the possibility that we may be unable to defer payment on certain aircraft into future fiscal years or take delivery of certain aircraft later than initially scheduled;
the possibility that we may impair our long-lived assets, including goodwill, property and equipment and investments in unconsolidated affiliates;
the possibility of changes in tax and other laws and regulations;
the possibility that the major oil companies do not continue to expand internationally and offshore;
the possibility that we may be unable to dispose of older aircraft through sales into the aftermarket;
the possibility that we may be unable to re-deploy our aircraft to regions with greater demand;
general economic conditions, including the capital and credit markets;

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.
General
We are the leading global industrial aviation services provider based on the number of aircraft operated. We have a long history in industrial aviation services through Bristow Helicopters Ltd. (“Bristow Helicopters”) and Offshore Logistics, Inc., which were founded in 1955 and 1969, respectively. We have major transportation operations in the North Sea, Nigeria and the U.S. Gulf of Mexico, and in most of the other major offshore energy producing regions of the world, including Australia, Brazil, Canada, Russia and Trinidad. We provide private sector SAR services in Australia, Canada, Norway, Russia, Trinidad and the United States. We provide public sector SAR services in the U.K. on behalf of the Maritime & Coastguard Agency. We also provide regional fixed wing scheduled and charter services in the U.K., Nigeria and Australia through our consolidated affiliates, Eastern Airways International Limited (“Eastern Airways”) and Capiteq Limited, operating under the name of Airnorth, respectively.Airnorth. These operations support our primary industrial aviation services operations in those markets, creating a more integrated logistics solution for our clients.
In fiscal year 2013, Bristow Helicopters was awarded 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.customers.
During the Current Period,Quarter, we generated approximately 69%65% of our consolidated operating revenue from external clientscustomers from oil and gas operations, approximately 16%19% from U.K. SAR operations and approximately 15%16% from fixed wing services, including charter and scheduled airline services that support our global helicopter operations.
We conduct our business in one segment: industrial aviation services. The industrial aviation services segment operations are conducted primarily through two hubs that include four regions:
Europe Caspian,
Africa,
Americas, and
Asia Pacific.
We primarily provide industrial aviation services to a broad base of major integrated, national and independent offshore energy companies. Our clientscustomers charter our helicopters primarily to transport personnel between onshore bases and offshore production platforms, drilling rigs and other installations. To a lesser extent, our clientscustomers also charter our helicopters to transport time-sensitive equipment to these offshore locations. These clients’customers’ operating expenditures in the production sector are the principal source of our revenue, while their exploration and development capital expenditures provide a lesser portion of our revenue. The clientscustomers for SAR services include both the oil and gas industry, where our revenue is primarily dependent on our clients’customers’ operating expenditures, and governmental agencies, where our revenue is dependent on a country’s desire to privatize SAR and enter into long-term contracts. As of December 31, 2017June 30, 2018, we operated 292286 aircraft (including 190187 owned aircraft and 10299 leased aircraft; 910 of the owned aircraft are held for sale) and our unconsolidated affiliates operated 114109 aircraft in addition to those aircraft leased from us.


The chart below presents (1) the number of aircraft in our fleet and their distribution among the regions of our industrial aviation services segment as of December 31, 2017June 30, 2018; (2) the number of helicopters which we had on order or under option as of December 31, 2017June 30, 2018; and (3) the percentage of operating revenue which each of our regions provided during the Current Period.Quarter. For additional information regarding our commitments and options to acquire aircraft, see Note 57 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report.

The 114109 aircraft operated by our unconsolidated affiliates do not include those aircraft leased from us. Includes 4441 helicopters (primarily medium) and 2219 fixed wing aircraft owned and managed by Líder Táxi Aéreo S.A.

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

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

Our Strategy
Our goal is to further strengthen our 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.
We will continue to transform our business to create financial sustainability, defined as positive cash flow, reduced leverage and an ability to refinance fiscal year 2023 debt maturities in absence of an offshore market recovery as the timing of a leading industrial aviation services provider for civilian SARrecovery remains uncertain. Fiscal year 2019 priorities include: (1) safety improvements with a refresh of Target Zero; (2) revenue growth by being competitive in a short-cycle market; (3) cost efficiencies building on the success of fiscal year 2018; (4) improving financial returns on capital with improved aircraft utilization.
While we are well-positioned to take advantage of the beginning of an offshore investment cycle, continued innovation and greater cost efficiencies will be required beyond fiscal year 2019 as we move from sustainability to pursue additional business opportunities that leverage our strengths in these markets. Our vision is to be a safe, financially strong, diversified global leader, succeeding no matter how challenging market conditions may be. To achieve this goal and vision,profitability. Specifically, we intendwill continue to employ our “STRIVE” strategy as follows:
Sustain Target Zero Safety Culture. Safety will always be our number one focus. The best approachWe continue to bedeliver Target Zero isperformance 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 ourcertain 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 clientscustomers safely, reliably and efficiently. We believe that we need to renew these strategies in order to thrive in an economy that is undergoing long-term structural change. Our Europe and Americas hub structure has allowed us to achieve reductions in general and administrative expenses down to approximately 12% of revenue compared to 14% in fiscal year 2015. Further, our hub structure allows us to take advantage of short-cycle work, which we define as short-term demand requests from our oil and gas customers for contracts measured in months rather than years. 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 continually 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 reduction and profitability.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 December 31, 2017,June 30, 2018, commercial helicopters under operating leases accounted for 40%39% of our LACE. See “Liquidity and Capital Resources — Financial Condition and Sources of Liquidity” included elsewhere in this Quarterly Report for further discussion of our capital structure and liquidity.

Value Added Acquisitions and Divestitures. We intend to pursue value-added acquisitions that not just make us bigger but better; that improve our competitive posturegenerate cost efficiencies that position us to thrive in an economy that is undergoing long-term structural change. We may also divest of 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 and sold three aircraft during the Current Quarter for proceeds of $8.1 million, of which $7.4 million was received in the Current Quarter and $0.7 million was received in July 2018. We currently have 10 aircraft held for sale and the average age of our fleet is approximately ten years. Additionally, our critical short and long-term goal is to significantly reduce our aircraft rent expense. During fiscal year 2018 and the Current Quarter, we returned four Airbus H225s and six Sikorsky S-92s to lessors. We intend to further reduce aircraft rent expense through lease returns as part of our ongoing strategy to return to profitability.
Execute on Bristow Transformation. We intend to sustain our strategyOur Europe and the effective transformation of our business by focusing on execution globally.
Fiscal year 2018 STRIVE priorities — DuringAmericas hub structure has allowed for global alignment with faster local market response and increased cost efficiency. Also, as discussed elsewhere in this Quarterly Report, we reached agreements with OEMs during fiscal year 2018 we are employing the following prioritiesto achieve $136 million in furtherance of the STRIVE strategy: (1) maintaining safety as our first priority; (2) achieving cost efficiencies, including the reduction of corporate general and administrative expenses to approximately 12% of revenues, while also implementing lean processes and improving productivity; (3) utilizing portfolio and fleet optimization, combined with pursuing original equipment manufacturers (“OEM”) cost recoveries and capital expenditure reduction to improve liquidity and reduce debt; and (4) achieving revenue growth through contract wins in our primary geographical hubs with a focus on delivering greater efficiencies to our core oil and gas clients.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 clientcustomer diversity which helps mitigate risks associated with a single market or client.customer.
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 as of July 1, 2014 to a low of approximately $26 per barrel in February 2016, with an increase to approximately $60$74 per barrel as of December 31, 2017.June 30, 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 clientscustomers 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 20182019 and have impacted both the offshore production and the offshore exploration activity of our clients,customers, with offshore production activity being impacted to a lesser extent. Although theThe largest share of our revenue relates to oil and gas production and our largest contract, the contract with the U.K. Department for Transport to provide public sector SAR contract,services for all of the U.K. (the “U.K. SAR contract”), is not directly impacted by declining oil prices,prices. However, the significant drop in the price of crude oil resulted in the rescaling, delay or cancellation of planned offshore projects which has negatively impacted our operations and could continue to negatively impact our operations in future periods.
The oil price environment is showing signs of stabilizing butwith 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 the North Sea. There have also been significant increases in front end engineering and design awards that, along with the stabilization of tie-back work and floating production storage and offloading unit utilization, has historically been a leading indicator of increased offshore activity. The helicopter transportation industry is benefiting from relatively low day rates for rigs, which in turn reduces our oil and gas customers’ 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 whenwhether this increased activity will lead to a recovery in offshore spending, will occur. Anand an extended period of reduced crude oil prices and related 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 clientscustomers 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.
Through the continued downturn we have been successful in preserving our liquidity and managing revenue and margin declines through cost reductions and capital efficiencies, diversification into other lines of service, such as SAR and fixed wing services, OEM cost recoveries and public and private financings.
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 clientscustomers to improve the efficiency of their operations. We achieved approximately $80.0 million of annualized cost reductions and cash savings in fiscal year 2017 relative to our original fiscal year 2017 operating plan by proactively implementing operating cost initiatives, and further cost reductions and cash savings have been put into effect during fiscal year 2018.
We increased our financial flexibility by amending certain financial covenants in each of our senior secured credit agreements and entering into new secured equipment financings that resulted in aggregate proceeds of $630 million funded in fiscal years 2017 and 2018. Additionally, in December 2017, we completed the sale of $143.8 million of 4½% Convertible Senior Notes due 2023 (the “4½% Convertible Senior Notes”) as discussed in Note 3 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report and under “Recent Events” below.

We worked with our OEMs to defer approximately $190 million of capital expenditures relating to fiscal years 2018 through 2020 into fiscal year 2020 and beyond and expect to achieve approximately $130 million in cost recoveries from OEMs in fiscal year 2018 related to ongoing aircraft issues, of which $125 million was recovered in the Current Quarter.
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 $350 million of the 8.75% Senior Secured Notes. In April 2018, we entered into a new ABL Facility as discussed in Note 4 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report and under “—Recent Events” below.
We worked with our original equipment manufacturers (“OEMs”) to defer approximately $190 million of capital expenditures relating to fiscal years 2018 through 2020 into fiscal year 2020 and beyond and achieved $136 million in cost recoveries from OEMs related to ongoing aircraft issues, of which $125 million was recovered in fiscal year 2018 and $11 million was recovered in May 2018.
We took significant steps to reduce general and administrative costs that included downsizing our corporate office and the size of our senior management team. Consistent with our STRIVE strategy, Bristow iswe are better positioned to win contracts because it iswe 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.

Tax Cuts and Jobs Act— On December 22, 2017, the president of the United States Congress enactedsigned into law tax legislation commonly known as the Tax Cuts and Jobs Act (the “Act”). The Act includes numerous changes in existing U.S. tax law, including a permanent reduction in(1) reducing the U.S. federal corporate income tax rate from 35% to 21%. The rate reduction takes effect on January 1, 2018. Further, the Act provides for; (2) requiring companies to pay a one-time “deemed repatriation” of accumulated foreigntransition 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. Under U.S. generally acceptedcorporations; 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 became applicable to us on April 1, 2018: (1) creation of a new minimum tax on base erosion and anti-abuse; (2) creation of additional limitations on deductible business interest expense; and (3) creation of additional limitations on the utilization of net operating loss carryforwards.
In December 2017, the SEC staff issued Staff Accounting Bulletin No. 118 (“SAB 118”), which addresses how a company recognizes provisional amounts when a company does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete its accounting principles, our net deferred tax liabilities are required to be revalued during the period in which the new tax legislation is enacted. We have made reasonable estimates for the changeeffect of the changes in the U.S. federal corporateAct. 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 ratereform and one-time “deemed repatriation”related disclosures. Consistent with guidance in SAB 118, for fiscal year 2018 we recorded provisional amounts for the transition tax on undistributed earnings of accumulated foreign earnings. We estimate the revaluation of U.S. net deferred tax liabilities will result in a one-time tax benefit of approximately $75.6$52.9 million, which was partially offset by an estimated $61.5foreign tax credits of $22.6 million. Also in fiscal year 2018, we recorded $53.0 million in tax expensebenefit as a result of the “deemed repatriation”revaluation of foreign earnings. We are still analyzing certain aspects ofour net deferred tax liabilities. Additional details regarding the Act and refiningthe impact on us are provided in Note 8 in the “Notes to Consolidated Financial Statements” included in our calculations.2018 Annual Report.

Any adjustments recorded to the provisional amounts will be included in income from operations as an impact onadjustment to our income taxes beginning after fiscal year 2018. 
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’s2019 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 Current Quarter and Current Period of $0.7 million and $7.2 million, respectively, which resulted from the combined loss on the sale and related impairment of assets included in loss on disposal of assets on our condensed 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 aan H225LP) model helicopter crashed near Turøy outside of Bergen, Norway resulting in the European Aviation Safety Agency (“EASA”) issuing airworthiness directives prohibiting flight of H225LP and AS332L2 model aircraft. On July 20, 2017, the U.K. CAA and NCAA issued safety and operational directives which detail the conditions to apply for the safe return to service of H225LP and AS332L2 model aircraft, where operators wish to do so. On July 5, 2018, the Accident Investigation Board Norway issued its final investigation report on the accident. The report cited a fatigue fracture within the epicyclic module of the main gear box as the cause of the accident, and issued safety recommendations in a number of areas, including gearbox design and certification requirements, failure tolerance, and continued airworthiness of the AS332L2 and the EC 225LP helicopters. We continue not to operate for commercial purposes our sole23 H225LP model aircraft, in Norway, our thirteen H225LP model aircraft in the U.K. or our six H225LP model aircraft in Australia, or for search and rescue purposes, including training and missions, any of our other four H225LP model aircraft in Norway or our other three H225LP model aircraft in Australia. Wewe are carefully evaluating next steps and demand for the H225LP model aircraft in our oil and gas and search and rescueSAR operations worldwide, with the safety of passengers and crews remaining our highest priority. During the three months ended December 31, 2017, we returned three of these H225LP models to the lessor; two were previously operating in Australia and one was previously operating in the U.K. During February 2018, we returned one H225LP model to the lessor that was previously operating in the U.K.
Separately, our efforts to successfully integrate AW189 aircraft into service for the U.K. SAR contract have been delayedcontinue with three of the five bases operational and a fourth expected to be online by October 1, 2018. As a result of the delays due to a product improvement plan with the aircraft. As a result,aircraft, the acceptance of four AW189 aircraft will bewere 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 approximately $130.0$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 the Current Quarter. For further details on the accounting treatment, see Note 1 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly 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 (“Term Loan Credit Facility”), $93.7 million of the Term Loan and $103.0 million of the $400 million revolving credit facility (“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 — On June 8, 2017, we announced structural and leadership changes intended to create a strategically realigned and profitable company in an unprecedented downturn. The new Bristow will have two primary geographical hubs in key areas of business, Europe and the Americas, resulting 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 Quarterly 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.
Brexit — In a referendum held on June 23, 2016, voters in the U.K. approved the exit of the U.K. (“Brexit”) from the E.U. On March 29, 2017, the U.K. government commenced the exit process under Article 50 of the Treaty of the European Union by notifying the European Council of the U.K.’s intention to leave the E.U. This notification starts a two-year time period for the U.K. and the remaining E.U. Member States to negotiate a withdrawal agreement.
For the Current Period and the year ended March 31, 2017, approximately 36% of our revenue was derived from contracts with customers in the U.K. and approximately 18% and 16% of our revenue was derived from contracts with customers in other European markets, respectively.

The consequences of Brexit, together with what may be 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 customers 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 Scotland, which could lead to a breakup of the U.K., creating further legal and regulatory uncertainty.
The Brexit vote has resulted in a significant decline in the value of British pound sterling and volatility in exchange rates is expected to continue as the terms of Brexit are negotiated. If the British pound sterling remains weak or continues to weaken, revenue under contracts denominated in British pound sterling will translate into fewer U.S. dollars. For the Current Period, revenue denominated in British pound sterling represented 34% of our revenue. 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. For discussion of the impact of changes in foreign currency exchange rates, including the British pound sterling, on our results, see “— Results of Operations — Current Quarter Compared to Comparable Quarter” and “— Results of Operations — Current Period Compared to Comparable Period” included elsewhere in this Quarterly Report.
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% devaluation of the naira versus the U.S. dollar from June 30, 2016 to December 31, 2017. For discussion of the impact of changes in foreign currency exchange rates, including the naira, on our results, see “— Results of Operations — Current Quarter Compared to Comparable Quarter” and “— Results of Operations — Current Period Compared to Comparable Period” included elsewhere in this Quarterly Report.
Selected Regional Perspectives
We own an approximate 20% voting interest and a 41.9% economic interest in Líder, a provider of helicopter and executive aviation services in Brazil. Brazil represents a significant part of our long term helicopter growth outlookindustry demand due to its concentration and size of its offshore oil reserves. However, in the short term, Brazil and, specifically, Petrobras continuescontinue to evidence uncertainty as the price of oil and Petrobras’ restructuring efforts have impacted the helicopter industry. Petrobras did not release any new tenders for multiple medium and large aircraft that were expected to commence in calendar year 2016. While this represents a contraction in short-term demand, Brazil’s impact on long-term helicopter demand is expected to be material. Petrobras represented 64% and 66% of Líder’s operating revenue in calendar years 2017 and 2016, respectively. As of December 31, 2017, we have no aircraft on lease to Líder.
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 request information and/or proposals.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 compared to the prior year for Líder with future opportunities for growth.growth although Líder faces significant competition from a number of global and local helicopter service providers.
CurrencyLíder’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 June 30, 2018 is $52.0 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 June 30, 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) providing technical aviation maintenance services through a wholly-owned Bristow Group entity,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 PAAN and BATSPAAN 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 the Current Period,Quarter, our primary foreign currency exposure was related to the British pound sterling, the euro, the Australian dollar, the Norwegian kroner and the Nigerian naira and our unconsolidated affiliates foreign currency exposure is primarily related to the Brazilian real. The Brexit event discussed above and elsewhere in this Quarterly Report is an example ofFor further details on this exposure and possiblethe related impact on our results of operations.operations, see “Item 7A.

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

(i) 
See information about special items during the Current Quarter and Comparable Quarter under “— Current Quarter Compared to Comparable Quarter” and Current Period and Comparable Period under “— Current Period Compared to Comparable Period” below.
(ii) 
Effective tax rate is calculated by dividing benefit (provision) for income tax by pretax net loss. Adjusted effective tax rate is calculated by dividing adjusted benefit (provision) for income tax by adjusted pretax net loss. Tax provision (benefit) on loss on disposal of assets and tax provision (benefit) on special items is calculated using the statutory rate of the entity recording the loss on disposal of assets or special item.  
(iii) 
These amounts are presented after applying the appropriate tax effect to each item and dividing by the weighted average shares outstanding during the related period to calculate the earnings per share impact.
(iv) 
Adjusted diluted earnings per share is calculated using the diluted weighted average number of shares outstanding of 35,368,21235,629,741 and 35,095,24035,227,434 during the Current Quarter and Comparable Quarter, respectively, and of 35,260,746 and 35,021,463 during the Current Period and the Comparable Period, respectively.
Management believes that adjusted EBITDA, adjusted benefit for income taxes, adjusted net loss and adjusted diluted loss per share (collectively, the “Non-GAAP measures”) provide relevant and useful information, which is widely used by analysts, investors and competitors in our industry as well as by our management in assessing both consolidated and regional performance.

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

The year-over-year increase in operating revenue was primarily driven by anincreases in U.K. SAR and fixed wing services revenue in our Europe Caspian and Africa regions. The increase in U.K. SAR services revenue due to additional bases coming onlineincluded the one-time benefit of $7.6 million in fiscal years 2017 and 2018, an increase in operating revenue from our fixed wing services in our Asia Pacific, Africa and Europe Caspian regions and an increase in operating revenue for our oil and gas services primarily in our Americas and Europe Caspian regions due to an increase in activity. The activity level increase across our business was driven mostly by short term contracts, ad hoc and increased flying on existing contracts as we continue to see stability in certain markets, especiallyOEM cost recoveries recognized in the North Sea off of Norway and in the shelf in the U.S. Gulf of Mexico.Current Quarter. Additionally, revenue increased by $10.8$10.5 million compared to the Comparable Quarter due to changes in foreign currency exchange rates, primarily related to the strengthening of the British pound sterling versus the U.S. dollar. Offsetting these increases was a decrease in operating revenue for our oil and gas services primarily in our Africa and Americas regions due to a decrease in activity, which was partially offset by an increase in activity in our Asia Pacific region.
For the Current Quarter, we reported a net loss of $8.3$32.1 million and a diluted loss per share of $0.23$0.90 compared to a net loss of $21.9$55.3 million and a diluted loss per share of $0.62$1.57 for the Comparable Quarter. The year-over-year change in net loss and diluted loss per share was primarily driven by one-time income tax benefits, higher revenue in the Current Quarter as discussed above, lower rent expense, resulting from OEM cost recoveries in Current Quarterlower general and impairment charges on goodwill recorded in the Comparable Quarter that did not recur in the Current Quarter.administrative expenses and a more favorable effective tax rate. These favorable changes were partially offset by higher interest expense and a higher loss on disposal of assetsunconsolidated affiliates in the Current Quarter.

The net loss and diluted loss per share for the Current Quarter was significantly impacted byincluded the following special items:
Organizationalorganizational restructuring costs of $2.8$1.7 million ($2.51.7 million net of tax), or $0.05 per share, included in direct cost and general and administrative expense, resulting from separation programs across our global organization designed to increase efficiency and reduce costs, and
A non-cash benefit of $15.1 million from tax items including a $75.6 million benefit related to the revaluation of net deferred tax liabilities to a lower tax rate resulting from the enactment of the Act in December 2017 and ongoing impact of valuation of deferred tax assets and recent financings of $1.0 million, partially offset by the impact of deemed repatriation of foreign earnings under the Act of $61.5 million.costs.
Additionally, we hadrealized a loss on disposal of assets of $4.6$1.7 million ($2.51.3 million net of tax) during the Current Quarter primarily related to a loss of $3.0 million from the sale or disposal of aircraft and other equipment.

The Current Quarter results also benefited from the impact of $12.2 million of OEM cost recoveries related to ongoing aircraft issuesrealized in the Current Quarter that resulted in a $125one-time benefit of $7.6 million increase in cash and liquidity,U.K. SAR operating revenue as discussed above, a reduction in the carrying value of certain aircraft within our fleet by $94.5$3.5 million a reduction in rent expense of $13.1and a $1.1 million (includedreduction in direct costs) and the recording of a liability of $17.4cost. We will recognize an additional $4.4 million as of December 31, 2017. The liability recorded as of December 31, 2017 reflects the value of the OEM cost recoveries to be recorded as a reduction in rent expense and an additional $2.3 million reduction in future periods, including $3.5 milliondirect cost over the remainder of fiscal year 2019 related to be recordedthese OEM cost recoveries. For further details, see Note 1 in the March 2018 quarter.“Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report.
Excluding the special itemsorganizational restructuring costs described above and the loss on disposal of assets, adjusted net loss and adjusted diluted loss per share were $18.5$29.1 million and $0.52,$0.82, respectively, for the Current Quarter. These adjusted results compare to adjusted net loss and adjusted diluted loss per share of $10.1$29.1 million and $0.29,$0.83, respectively, for the Comparable Quarter. Additionally, adjusted EBITDA improved to $35.0$26.8 million in the Current Quarter from $22.9$15.2 million in the Comparable Quarter. The benefit from the OEM cost recoveries described above is included withwithin adjusted net income, adjusted earnings per share and adjusted EBITDA in the Current Quarter.
The year-over-yearAdjusted EBITDA, adjusted net loss and adjusted diluted loss per share benefited from the increase in revenue, decrease in rent and general and administrative expense, and favorable impact of changes in foreign currency exchange rates compared to the Comparable Quarter. These items were mostly offset by increased interest expense, resulting in no significant change in adjusted net loss and adjusted diluted loss per share is primarily driven by an adjusted income tax expense in the Current Quarter compared to an adjusted income tax benefit in the Comparable Quarter and anyear-over-year. The increase in interestrevenue and decrease in rent expense partially offset by the increase in U.K. SAR, fixed wing services and oil and gas services revenue discussed above and the benefit fromincludes the OEM cost recoveries. The year-over-year change in adjusted EBITDA was primarily driven by the increase in U.K. SAR, fixed wing services and oil and gas services revenue discussed above and the benefit from the OEM cost recoveries.recoveries described above.

The most significant foreign exchange impact related to a $1.8$5.1 million favorable impact from changes in foreign currency exchange rates in the Current Quarter primarily driven by the impact of the appreciating British pound sterling on the translation of our results in our Europe Caspian region. During the Current Quarter, we benefited from the appreciation of the British pound sterling from the Comparable Quarter where a majority of our revenue is contracted in British pound sterling with our expense being more evenly split between U.S. dollars and British pound sterling, resulting in a significant net revenue exposure to the British pound sterling that translated into higher U.S. dollar earnings for reporting purposes. Additionally, results for the Current Quarter were impacted byPartially offsetting this favorable impact was a $0.5$1.5 million decreaseincrease in unfavorable foreign currency exchange rate impact from our investment in Líder in Brazil. Partially offsetting these favorable impacts wasBrazil and a $1.3$1.4 million unfavorable impact from lowerhigher transaction gainslosses in the Current Quarter compared to the Comparable Quarter.
Direct costs increased 4.4%cost decreased 1.9%, or $11.5$5.5 million, year-over-year primarily due to a $7.3$7.1 million increase in maintenance expense, a $7.2 million increasedecrease in salaries and benefits primarily due to a $4.5 million increasedecrease in fuel coststhe number of employees and a $4.0 million increase in other direct costs, all of which are attributable to an increase in activity, partially offset by a $11.5$8.5 million decrease in rent expense primarily due to return of leased aircraft and OEM cost recoveries.recoveries, partially offset by a $5.3 million increase in fuel due to increased fuel prices and increased activity and a $4.8 million increase in other direct costs due to an increase in activity.
Reimbursable expense increased 20.6%30.1%, or $2.5$3.7 million, primarily due to new contracts in our Asia Pacific region and Norway.
Depreciation and amortization expense increased 6.4%, or $1.9 million, to $31.7remained mostly flat at $30.9 million for the Current Quarter from $29.8compared to $31.1 million for the Comparable Quarter. The increase in depreciation and amortization expense is primarily due to additional new aircraft and information technology costs being capitalized and depreciated in the Current Quarter, partially offset by a $0.7 million reduction to depreciation expense related to OEM cost recoveries.
General and administrative expense decreased 4.5%14.1%, or $2.0$6.6 million, in the Current Quarter, as compared to the Comparable Quarter primarily due to a decrease in compensation expense of $2.6$3.7 million primarily resulting from a reduction in long-term incentive compensation costs,severance expense of $7.4 million, partially offset by an increase in short-term and long-term incentive compensation costs of $0.6$3.7 million, primarily related toa reduction in professional fees of $1.3 million and a reduction of various other general and administrative expenses of $1.6 million including information technology, costs.training and travel as part of continued cost reduction efforts.
Loss on impairment for the Comparable Quarter includes $8.7a $1.2 million of goodwill impairments related to Eastern Airways.impairment charge on inventory used on our training fleet.

During the Comparable Quarter, the gain on disposal of assets included a gain of $2.3 million from the sale or disposal of aircraft and other equipment, andpartially offset by impairment charges totaling $1.6 million related to assets held for sale. During the Comparable Quarter, the loss on disposal of assets included impairment charges totaling $0.2 million related to assets held for sale and a loss of $0.7 million from the sale or disposal of aircraft and other equipment.

Interest expense, net, increased 56.8%69.4%, or $6.9$11.1 million, year-over-year primarily due to an increase in interest resulting from an increase in borrowings and a decreasean increase in capitalized interest resulting from lower average construction in progress. Additionally, during the Current Quarter we wrote-off $0.5 millionamortization of deferred financing fees related to early extinguishment of debt.debt discount.
For further details on income tax expense, see “— Region Operating Results — Taxes” included elsewhere in this Quarterly Report.

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

The year-over-year increase in revenue in the Current Period 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 increase in operating revenue from our fixed wing services in our Asia Pacific, Africa and Europe Caspian regions. These increases were partially offset by a decrease in our oil and gas services driven by declines in our Asia Pacific and Africa regions, partially offset by increases in oil and gas services in our Europe Caspian and Americas regions. See further discussion of operating revenue by region under “—Region Operating Results.” Additionally, revenue decreased by $4.9 million compared to the Comparable Period due to changes in foreign exchange rates, primarily related to the weakening of the British pound sterling versus the U.S. dollar.
For the Current Period, we reported a net loss of $94.8 million and a diluted loss per share of $2.69 compared to a net loss of $92.5 million and a diluted loss per share of $2.64 for the Comparable Period. The year-over-year change in net loss and diluted loss per share was primarily driven by higher revenue from U.K. SAR and fixed wing services in the Current Period discussed above, higher inventory and goodwill impairment charges recorded in the Comparable Period and a decrease in general and administrative expense primarily from lower salaries and benefits in the Current Period. These favorable changes were partially offset by the decline in the oil and gas services revenue and higher interest expense.

The net loss for the Current Period was significantly impacted by the following special items:
Organizational restructuring costs of $15.2 million ($11.3 million net of tax) included in general and administrative expense, which includes severance expense of $13.9 million related to separation programs across our global organization designed to increase efficiency and reduce costs and other restructuring costs of $1.3 million,
Impairment of inventories of $1.2 million ($0.8 million net of tax) included in loss on impairment, and
A non-cash expense of $3.0 million from tax items including a $75.6 million benefit related to the revaluation of net deferred tax liabilities to a lower tax rate resulting from the enactment of the Act in December 2017, partially offset by the impact of deemed repatriation of foreign earnings under the Act of $61.5 million, the ongoing impact of valuation of deferred tax assets of $14.7 million and 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 $2.4 million.
Additionally, we had a loss on disposal of assets of $12.4 million ($20.5 million net of tax) during the Current Period primarily related to $11.3 million for impairment charges on assets held for sale (including $7.2 million impairment and loss on disposal related to the Bristow Academy disposal group).
Excluding the special items described above and the loss on disposal of assets, adjusted net loss and adjusted diluted loss per share were $59.2 million and $1.68, respectively, for the Current Period. These adjusted results compare to adjusted net loss and adjusted diluted loss per share of $34.4 million and $0.98, respectively, for the Comparable Period. Additionally, adjusted EBITDA improved to $82.5 million in the Current Period from $67.4 million in the Comparable Period. Results for the Current Period were also positively impacted by a reduction in rent expense of $13.1 million included in direct costs related to OEM cost recoveries.
The year-over-year change in adjusted EBITDA was primarily driven by higher revenue from U.K. SAR and fixed wing services in the Current Period discussed above and a decrease in general and administrative expense primarily from lower salaries and benefits in the Current Period. These favorable changes were partially offset by the decline in oil and gas revenue discussed above. The year-over-year change in adjusted net loss and diluted earnings per share was impacted by the same items that impacted adjusted EBITDA and higher interest expense.

The most significant foreign exchange impact related to a $4.3 million unfavorable impact from changes in foreign currency exchange rates in the Current Period driven by the impact of the depreciating British pound sterling resulting from Brexit on the translation of our results in our Europe Caspian region, partially offset by a favorable impact of the devalued naira in our Africa region. Partially offsetting these unfavorable impacts was a $3.0 million favorable impact from transaction gains in the Current Period compared to transaction losses in the Comparable Period. Additionally, results for the Current Period were impacted by a $0.9 million decrease in unfavorable foreign currency exchange rate impact from our investment in Líder in Brazil.

Direct costs increased 1.3%, or $10.6 million, year-over-year primarily due to a $17.2 million increase in maintenance expense and a $11.2 million increase in fuel primarily due to an increase in activity, partially offset by lower headcount across all regions due to the benefit of organizational restructuring efforts reflected in a $7.0 million decrease in salaries and benefits and $5.6 million decrease in freight costs and a $5.2 million decrease in various other costs.
Reimbursable expense increased 11.2%, or $4.3 million, primarily due to new contracts in Norway.
Depreciation and amortization expense increased 1.1%, or $1.1 million, to $94.1 million for the Current Period from $93.1 million for the Comparable Period. The increase in depreciation and amortization expense is primarily due to additional new aircraft and information technology costs being capitalized and depreciated in the Current Period, partially offset by a $0.7 million reduction in depreciation expense related to OEM cost recoveries. Additionally, we recorded accelerated depreciation of $9.3 million in the Comparable Period as a result of fleet changes for older aircraft.
General and administrative expense decreased 7.1%, or $10.6 million, in the Current Period, as compared to the Comparable Period primarily due to an $8.6 million decrease in compensation expense primarily related to lower salaries and benefits due to a reduction in headcount across all regions and a $3.3 million decrease in professional fees, partially offset by a $1.3 million increase in various other costs primarily including rent expense.
Loss on impairment for the Current Period includes a $1.2 million impairment charge on inventory used on our training fleet. Loss on impairment for the Comparable Period includes $8.7 million of goodwill impairment related to Eastern Airways and $7.6 million of inventory impairments.
Loss on disposal of assets decreased $0.7 million, to a loss of $12.4 million for the Current Period from a loss of $13.1 million for the Comparable Period. The loss on disposal of assets in the Current Period included impairment charges totaling $11.3 million related to assets held for sale (including $7.2 million impairment and loss on disposal related to the Bristow Academy disposal group) and a loss of $1.1 million from the sale or disposal of aircraft and other equipment. During the Comparable Period, the loss on disposal of assets included impairment charges totaling $11.4 million related to assets held for sale and a loss of $1.7 million related to the sale of aircraft and other equipment.
Earnings from unconsolidated affiliates, net of losses, decreased $1.4 million to earnings of $3.4 million for the Current Period from earnings of $4.8 million in the Comparable Period. The decrease in earnings from unconsolidated affiliates, net of losses, primarily resulted from a decrease in earnings from our investment in Líder in Brazil to $5.7 million in the Current Period from $6.9 million in earnings in the Comparable Period primarily due to a decrease in activity. Our earnings from Lider in the Current Period were also impacted by less of an unfavorable impact of foreign currency exchange rate changes of $0.9 million.
Interest expense, net, increased 55.4%, or $19.1 million, year-over-year primarily due to an increase in interest resulting from an increase in borrowings and a decrease in capitalized interest resulting from lower average construction in progress. Additionally, during the Current Period we wrote-off $1.1 million of deferred financing fees related to early extinguishment of debt.
For further details on income tax expense, see “— Region Operating Results — Taxes” included elsewhere in this Quarterly Report.

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

The Europe Caspian region comprises all of our operations and affiliates in Europe, including oil and gas operations in the U.K. and Norway, Eastern Airways fixed wing operations and public sector SAR operations in the U.K. and our operations in Turkmenistan.
Current Quarter Compared to Comparable Quarter
The increase in operating revenue in the Current Quarter primarily resulted from an increase of $10.5$13.7 million from the start-up of additionalfor U.K. SAR bases,revenue including a one-time benefit of OEM cost recovery of $7.6 million, an increase of $7.2$3.9 million in Norway primarily due to an increase in activity and short-term contracts and an increase of $4.4$6.9 million in fixed wing revenue from Eastern Airways andAirways. Additionally, revenue in this region benefited from a favorable year-over-year impact of changes in foreign currency exchange rates of $10.1$10.8 million. Partially offsetting these increases was a decrease in U.K. oil and gas revenue of $5.0 million primarily resulting from the continued impact of the industry downturn on drilling activity. Eastern Airways contributed $29.5$34.8 million and $25.1$27.9 million in operating revenue for the Current Quarter and Comparable Quarter, respectively.
A substantial portion of our operations in the Europe Caspian region are contracted in the British pound sterling, which depreciated significantly against the U.S. dollar in the Comparable Quarter asCurrent Quarter. We recorded a result of Brexit. As a result of the changes in the British pound sterling, adjusted EBITDA was favorably impacted from foreign exchange changesgain of $0.7$1.5 million duringin the Current Quarter compared to an unfavorable impactand a foreign exchange loss of $11.3$0.4 million during the Comparable Quarter. The negative impact in the Comparable Quarter primarily related to a loss of $10.7 million from the revaluation of assets and liabilities on British pound sterling functional currency entities as of December 31, 2016,June 30, 2018 and 2017, respectively, which is recorded in other income (expense), net. This compares to a foreignnet and included in adjusted EBITDA. Net of the translation and revaluation impacts, adjusted EBITDA was favorably impacted by $6.6 million resulting from the change in exchange gain within other income (expense), net of $1.3 million inrates during the Current Quarter. A further weakening or strengthening of the British pound sterling could result in additional foreign exchange volatility in future quarters.
DuringAs discussed above, the Current Quarter we recordedresults benefited from OEM cost recoveries realized in the Current Quarter related to ongoing aircraft issues that resulted in a one-time benefit of $7.6 million in U.K. SAR operating revenue, a $2.7 million reduction toin rent expense and a $1.1 million reduction in direct cost. We will recognize an additional $2.1 million reduction in rent expense and an additional $2.3 million reduction in direct cost over the remainder of $7.1 millionfiscal year 2019 related to these OEM cost recoveries in our Europe Caspian region related to OEM cost recoveries. This item isresults. These items are included in operating income and adjusted EBITDA in the Current Quarter. Additionally, during the Comparable Quarter, we recorded an impairment charge of $8.7 million for the remaining goodwill related to Eastern Airways, which contributed to the operating loss in the Comparable Quarter, but was adjusted for in our calculation of adjusted EBITDA. For further details, see Note 1 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report.
Operating income, operating margin, adjusted EBITDA and adjusted EBITDA margin increased in the Current Quarter primarily due to the increase in operating revenue discussed above, the benefit to rent expense and direct cost in the Current Quarter related to OEM cost recoveries, the benefit of the return of leased aircraft and favorable year-over-year impacts from changes in foreign currency exchange rates, with operating income and operating margin also improving due to the goodwill impairment charge recorded in the Comparable Quarter. 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 $4.1 million and a negative $2.1 million in adjusted EBITDA for the Current Quarter and Comparable Quarter, respectively.

The increase in operating revenue in the Current Period primarily resulted from an increase of $26.8 million in Norway primarily due to an increase in activity and short-term contracts and an increase of $18.7 million from the start-up of U.K. SAR bases compared to the Comparable Period. Partially offsetting these increases was a decrease in U.K. oil and gas revenue of $18.0 million resulting from the continued impact of the industry downturn on drilling activity and an unfavorable year-over-year impact of changes in foreign currency exchange rates of $6.5 million. Eastern Airways contributed $87.8 million and $85.9 million in operating revenue for the Current Period and Comparable Period, respectively.
During the Current Period, we recorded a reduction to rent expense of $7.1 million in our Europe Caspian region related to OEM cost recoveries. This item is included in operating income and adjusted EBITDA in the Current Period. Additionally, during the Comparable Period, we recorded an impairment charge of $8.7 million for the remaining goodwill related to Eastern Airways, which was included in operating income, but was adjusted for in our calculation of adjusted EBITDA. For further details, see Note 1 in the “Notes to Consolidated Financial Statements” included elsewhere in this Quarterly Report.
A substantial portion of our operations in the Europe Caspian region are contracted in the British pound sterling, which depreciated significantly against the U.S. dollar in the Comparable Period as a result of Brexit. We recorded a foreign exchange gain of $2.8 million in the Current Period and foreign exchange loss of $18.7 million in the Comparable Period from the revaluation of assets and liabilities on British pound sterling functional currency entities as of September 30, 2017 and 2016, 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 $4.8 million and negatively impacted by $29.2 million resulting from the change in exchange rates during the Current Period and Comparable Period, respectively. A further weakening or strengthening of the British pound sterling could result in additional foreign exchange volatility in future periods.
Operating income, adjusted EBITDA and adjusted EBITDA margin increased in the Current Period primarily due to the increase in operating revenue, the benefit to rent expense in the Current Period 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 $3.7$0.1 million and a negative $0.2positive $0.1 million in adjusted EBITDA for the Current PeriodQuarter and Comparable Period,Quarter, respectively.

Current Quarter Compared to Comparable Quarter
Operating revenue for Africa decreased in the Current Quarter due to an overall decrease in activity compared to the Comparable Quarter. Activity declined with certain clientscustomers and certain contracts ended, including a contract that expired on March 31, 2018, reducing revenue by $5.8$20.5 million, which was only partially offset by an increase in activity with other clientscustomers increasing revenue by $3.1$5.4 million. Additionally, fixed wing services in Africa generated $2.0$2.2 million and $1.0$1.8 million in operating revenue for the Current Quarter and Comparable Quarter, respectively.
Operating income, remained mostly flat whileoperating margin, adjusted EBITDA and adjusted EBITDA margin decreased as a result of the decrease in operating revenue in the Current Quarter, primarily duewhich was only partially offset by a decrease in direct cost and general and administrative expenses. Additionally, during the Current Quarter, we incurred $1.5 million of demobilization costs related to the impact of changes in foreign currency exchange rates, which negatively impacted adjusted EBITDA by $2.2 million compared to the Comparable Quarter.

a significant contract that expired on March 31, 2018 and was not renewed.
As previously discussed, we have seen recent changes in the Africa region as a result of increased competition entering the Nigerian market. Additionally, changing regulations andthe uncertainty of the political environment could have made, and are expectedan impact on the Nigerian market.  In particular, nationwide elections in early 2019 could affect the level of activity in the months leading to continue to make, our operating results for Nigeria unpredictable.the elections. Market uncertainty related to the oil and gas downturn has continued in this region putting smaller clientscustomers under increasing pressure as their activity declined, which reduced our activity levels and overall pricing. We implemented cost reduction measures in advance of these reductions and expect additional efficiencies in the future.
Current Period Compared to Comparable Period
Operating revenue for Africa decreased in the Current Period due to an overall decrease in activity compared to the Comparable Period. Activity declined with certain clients and certain contracts ended, reducing revenue by $13.6 million, which was only partially offset by an increase in activity with other clients increasing revenue by $4.2 million. Additionally, fixed wing services in Africa generated $5.5 million and $2.4 million of operating revenue for the Current Period and Comparable Period, respectively.
Operating income, operating margin, adjusted EBITDA and adjusted EBITDA margin increased in the Current Period primarily due to an $11.0 million decline in direct costs, partially offset by the decrease in revenue discussed above. Additionally, operating income and operating margin improved in the Current Period due to lower depreciation expense. During the Comparable Period, we recorded $5.0 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 $1.3 million compared to the Comparable Period as expenses denominated in naira translated into less U.S. dollars for reporting purposes.
Additionally, during the Current and Comparable Periods, we recorded $0.7 million and $4.4 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.

We estimate the full-year effective tax rate from continuing operations and apply this rate to our year-to-date income from continuing operations. In addition, we separately calculate the tax impact of unusual or infrequent items, if any. The tax impact of such unusual or infrequent items is treated discretely in the quarter in which they occur.
The relationship between our provision for or benefit from income taxes and our pre-tax book income can vary significantly from period to period considering, among other factors, (a) the overall level of pre-tax book income, (b) changes in the blend of income that is taxed based on gross revenues or at high effective tax rates versus pre-tax book income or at low effective tax rates and (c) our geographical blend of pre-tax book income. Consequently, our income tax expense or benefit does not change proportionally with our pre-tax book income or loss. Significant decreases in our pre-tax book income typically result in higher effective tax rates, while significant increases in pre-tax book income can lead to lower effective tax rates, subject to the other factors impacting income tax expense noted above. The increasechange in our effective tax rate excluding discrete items for the Current Quarter compared to the Comparable Quarter primarily related to an increasechanges in the blend of earnings taxed in relatively high taxed jurisdictions versus low taxed jurisdictions. Additionally, during the Current Quarter and Comparable Quarters,Quarter, we increased our valuation allowance by $2.1$1.0 million and $3.7$11.2 million, respectively, which also increased our effective tax rate. During the Current and Comparable Periods, we increased our valuation allowance by $13.4 million and $19.3 million, respectively.
Valuation allowances represent the reduction of our deferred tax assets. We evaluate our deferred tax assets quarterly which requires significant management judgment to determine the recoverability of these deferred tax assets by assessing whether it is more likely than not that some or all of the deferred tax asset will be realized before expiration. After considering all available positive and negative evidence using a “more likely than not” standard, we believe it is appropriate to value against deferred tax assets related to foreign tax credits and certain foreign net operating losses. As a result, for the Current Quarter and Comparable Quarters,Quarter, we recorded a valuation allowance of $2.1$1.0 million and $3.7$11.2 million, respectively, against net operating losses in certain foreign jurisdictions. For the Current and Comparable Periods,Quarter, we recorded a valuation allowance of $7.6 million and $11.0 million, respectively,against foreign tax credits. No valuation allowance against foreign tax credits was recorded for the Current Quarter. For the Current Quarter and $5.8Comparable Quarter, we recorded a valuation allowance of $1.0 million and $8.3$3.6 million, respectively, against net operating losses in certain foreign jurisdictions. These valuation allowances recorded inDuring the CurrentComparable Quarter, and Current Period combined with the impact of ongoing valuation allowances on our overall effective tax rate for fiscal year 2018 resulted in additional non-cash tax benefit of $1.6 million in the Current Quarter and expense of $14.7 million in$13.9 million. Additionally, for the Current Period. Additionally,same period, we recorded 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 tax benefit of $0.6 million in the Current Quarter and additional tax expense of $2.4 million in the Current Period.

$1.0 million.
On December 22, 2017, the United States Congress enacted the Act. The Act includes numerous changes in existing U.S. tax law, including a permanent reduction in the U.S. federal corporate income tax rate from 35% to 21%. The rate reduction takes effect on January 1, 2018. Further, the Act provides for a one-time “deemed repatriation” of accumulated foreign earnings of certain foreign corporations. Under U.S. generally accepted accounting principles, our net deferred tax liabilities are required to be revalued during the period in which the new tax legislation is enacted. We have made reasonable estimates for the change in the U.S. federal corporate income tax rate and one-time “deemed repatriation” of accumulated foreign earnings. We estimateFor the year ended March 31, 2018, our provision for income tax included provisional amounts for the revaluation of U.S. net deferred tax liabilities, will result in a one-time tax benefit of approximately $75.6 million offset by an estimated $61.5 million in tax expense as a resultthe impact of the “deemed repatriation” of foreign earnings. We are still analyzing certain aspectsThe provisional amounts associated with the one-time “deemed repatriation” and the re-measurement of deferred tax assets and liabilities due to the reduction in the corporate income tax rate will be adjusted over time as more guidance becomes available.

Certain provisions under the Act and refining our calculations.
Because of the complexity, we are continuingbecame applicable to evaluate certain provisions of the Act which may have an impactus on April 1, 2018 and our income taxes beginning after fiscal year 2018. tax provision for the three months ended June 30, 2018 includes the tax implications of these provisions. These provisions include Global Intangible Low-Taxed Income (“GILTI”), Base Erosion and Anti-Avoidance Tax (“BEAT”), Foreign Derived Intangible Income (“FDII”), and certain limitations on the deduction of interest expense and utilization of net operating losses.
Liquidity and Capital Resources
Cash Flows
Operating Activities
Net cash flows used byin operating activities were $9.344.1 million and $14.1$51.2 million during the Current PeriodQuarter and Comparable Period,Quarter, respectively. The decrease in net cash flows used byin operating activities in the Current PeriodQuarter resulted from a lower net loss, and a decreasepartially offset by an increase in cash flow used in working capital changes. Changes in non-cash working capital used $18.241.5 million and $18.832.1 million in cash flows from operating activities for the Current PeriodQuarter and Comparable Period,Quarter, respectively. Cash flows from operations for the Current Period includes $30.5 million related to OEM cost recoveries of which $20.1 million is included in cash flows from operations before working capital changes and $10.4 million is included in working capital changes.
Investing Activities
Cash flows used in investing activities were $1.1 million during the Current Quarter and cash flows provided by investing activities were $106.6 million during the Current Period and cash flows used by investing activities was $105.129.4 million during the Comparable Period.Quarter. Cash was used primarily for capital expenditures as follows:

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

The following table summarizes our significant contractual obligations and other commercial commitments on an undiscounted basis as of December 31, 2017June 30, 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 December 31, 2017June 30, 2018. Additional details regarding these obligations are provided in Notes 4, 5, 6, 7 and 9 in the “Notes to Consolidated Financial Statements” included in the fiscal year 20172018 Annual Report and in Notes 3, 4, 5, 7 and 79 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report.

Represents expected funding for defined benefit pension plans 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 five years. As of December 31, 2017,June 30, 2018, we had recorded on our balance sheet a $54.3$30.5 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) 
We have an agreement to defer payment of approximately $63 million in capital expenditures out of fiscal year 2018 and into future periods which is not reflected in the table above.
(7)
Includes $4.4 million for final payments for aircraft delivered during fiscal year 2017 that is included in accounts payable as of December 31, 2017.

Other purchase obligations primarily represent unfilled purchase orders for aircraft parts commitments associated with upgrading facilities at our bases and non-cancelable power-by-the-hour maintenance commitments. For further details on the non-cancelable power-by-the-hour maintenance commitments, see Note 1 in the “Notes to Consolidated Financial Statements” included in the fiscal year 20172018 Annual Report.

(10)
Includes $3.1 million related to Airnorth as of December 31, 2017. 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 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 condensed 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 condensed consolidated statements of operations.
Capital Commitments and Other Uses of Cash
We have commitments and options to make capital expenditures over the next seven fiscal years to purchase additional aircraft, including aircraft associated with the commitments reflected in the table above. Although a similar number of our existing aircraft may be sold during the same period, the additional aircraft on order are expected to provide incremental fleet capacity in terms of revenue, operating margin and adjusted EBITDA margin. See Note 57 in the “Notes to Condensed Consolidated Financial Statements” included elsewhere in this Quarterly Report for a detail of the number of aircraft under commitments and options expected to be delivered in the current and subsequent seven fiscal years by aircraft size along with the related expenditures, and for a rollforward of aircraft commitments and options through February 8,June 30, 2018.
As discussed under “— Executive Overview — Our Strategy”, cash may also be used in future periods to repurchase or otherwise retire debt or for any acquisition opportunities we believe are aligned with our long-term strategy.
Financial Condition and Sources of Liquidity
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.
Substantially allAs of June 30, 2018, approximately 22% 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. We expect to meet the continuing funding requirements of our U.S. operations with cash generated by such U.S. operations, cash from earnings generated by non-U.S. operations that are not indefinitely reinvested and our existing Revolving Credit Facility. If cash held by non-U.S. operations is required for funding operations in the U.S., we wouldmay make a provision for additional foreign taxestax in connection with repatriating this cash, which may be materialis not expected to have a significant impact on our cash flow and results of operations.
We expect that our cash on deposit as of February 2,July 27, 2018 of approximately $98.1$320.7 million, proceeds from aircraft sales, and available borrowing capacity of $33.9 million under our Revolving CreditABL Facility ($387.6 million as of February 2, 2018)described under “Executive Overview — Market Outlook — Recent Events — ABL Facility”, as well as any future financings (which may include additional equipment financings and capital market transactions), will be sufficient to satisfy our operating needs, existing capital commitments and other contractual cash obligations, including our debt obligations. However, we may require capital in excess of the amount available from these sources and we may need to pursue financings or capital market transactions,seek additional sources of liquidity, complete aircraft sales or defer capital expenditures in order to have sufficient liquidity to satisfy operating needs, existing capital commitments and other contractual obligations, including debt obligations due in April 2019. The available borrowing capacity under our Revolving Credit Facility was $387.6 million as of December 31, 2017. While we plan to continue to be disciplined concerning future capital commitments, we also intend to continue managing our capital structure and liquidity position with external financings, as needed. Our strategy will involve funding our short-term liquidity requirements with borrowings under our Revolving Credit Facility and funding our long-term capital needs with operating leases, bank debt and private and public debt and equity offerings.obligations.
