When used herein, the words “anticipates,” “expects,” “believes,” “seeks,” “hopes,” “intends,” “plans,” “projects” and similar words and expressions are intended to identify forward-looking statements.

These forward-looking statements, and the assumptions on which they are based, (i) are not guarantees of future events, (ii) are inherently speculative and (iii) are subject to significant risks,risk and uncertainties. Actual events and results may differ materially from those anticipated, estimated, projected or implied by us in those statements if one or more of these risks or uncertainties materialize, or if our underlying assumptions prove incorrect. All of our forward-looking statements are qualified in their entirety by reference to our discussion of certain important factors that could cause our actual results to differ materially from those anticipated, estimated, projected or implied by us in those forward-looking statements. Factors that could cause our results to differ materially from the expectations expressed in such forward-looking statements include but are not limited to the following:

risks and uncertainties relating to our Chapter 11 Cases, including but not limited to: our ability to refinanceobtain Bankruptcy Court approval with respect to motions in the Chapter 11 Cases; the effects of the Chapter 11 Cases on our short-term debtCompany and our various constituents; the impact of Bankruptcy Court rulings in the Chapter 11 Cases; our ability to develop and implement a plan of reorganization that will be approved by the Bankruptcy Court and the ultimate outcome of the Chapter 11 Cases in general; the length of time we will operate under the Chapter 11 Cases; attendant risks associated with restrictions on our ability to pursue our business strategies; risks associated with third-party motions in the Chapter 11 Cases; the potential adverse effects of the Chapter 11 Cases on our liquidity; the potential material adverse effect of claims that are not discharged in the Chapter 11 Cases; uncertainty regarding our ability to retain key personnel; and uncertainty and continuing risks associated with our ability to achieve our stated goals and continue as a going concern;

illiquidity in the trading of our substantial indebtednesssecurities, including limitations caused by the delisting of our common stock from Nasdaq and operating lease commitments, including any failure to meet the financial covenants orsubsequent trading of our securities in the other terms and conditions thereof;over-the-counter market;
reduction in demand for our services due to volatility of oil and gas prices and the level of domestic and overseas exploration and production activity, which depends on several factors outside of our control;
our dependence on a small number of customers for a significant amount of our revenue and our significant credit exposure within the oil and gas industry;
the adverse impact of customers electing to terminate or reduce our services;
any failure to maintain our strong safety record;
our ability to secure favorable customer contracts or otherwise remain able to profitably deploy our existing fleet of aircraft;
the availability of adequate insurance;

the special risks of our air medical operations, including collections risks and potential medical malpractice claims;

our ability to timely realize the anticipated benefits of our December 29, 2017 acquisition of the HNZ Offshore Business (as defined below in Item 2 of Part I of this report);additional offshore operations;
the hazards associated with operating in an inherently risky business, including the possibility that regulators could ground our aircraft for extended periods of time or indefinitely;

Additional factors or risks that we currently deem immaterial, that are not presently known to us, that arise in the future or that are not specific to us could also cause our actual results to differ materially from our expected results. Given these uncertainties, investors are cautioned not to unduly rely upon our forward-looking statements, which speak only as of the date made. PHI

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
1. BASIS OF PRESENTATION
The accompanying unaudited condensed consolidated financial statements include the accounts of PHI, Inc. and its subsidiaries (“PHI” or the “Company” or “we” or “our”). In the opinion of management, these condensed consolidated financial statements reflect all adjustments, consisting of only normal, recurring adjustments, necessary to present fairly the financial results for the interim periods presented. These condensed consolidated financial statements and the accompanying notes should be read in conjunction with the consolidated financial statements and the accompanying notes contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017.2018.
Our financial results, particularly as they relate to our Oil and Gas segment, are influenced by seasonal fluctuations as discussed in the Company’sour Annual Report on Form 10-K for the year ended December 31, 2017.2018. For this and other reasons, the results of operations for interim periods are not necessarily indicative of the operating results that may be expected for a full fiscal year.

Going Concern - The financial statements accompanying this Quarterly Report have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”), which contemplates our continuation as a going concern. ForAs discussed further in Note 2 below, our operations are currently subject to the reasonsjurisdiction of the Bankruptcy Code.
The accompanying interim Unaudited Condensed Consolidated Financial Statements have been prepared assuming that PHI will continue as a going concern and contemplates continuity of operations, realization of assets and satisfaction of liabilities and commitments in the normal course of business. Our ability to continue as a going concern is contingent upon our ability to comply with the financial and other covenants contained in the Blue Torch term loan described in Note 5,6, and our ability to successfully develop and, subject to the classification ofBankruptcy Court's approval, implement, a restructuring plan, among other factors. We have significant indebtedness. As a result, our indebtedness as current liabilities due within one yearfinancial condition and other conditionsthe risks and uncertainties surrounding our Chapter 11 proceedings raise substantial doubt aboutas to our ability to continue as a going concern.
Under the absolute priority scheme established by the Bankruptcy Code, unless our creditors agree otherwise, all of our pre-petition liabilities and post-petition liabilities must be satisfied in full before the holders of our existing common stock may receive any distribution or retain any property under a plan of reorganization. The ultimate recovery to creditors and/or shareholders, if any, will not be determined until confirmation and implementation of a plan or plans of reorganization. We can give no assurance that any recovery or distribution of any amount will be made to any of our creditors or shareholders. Our plan of reorganization could result in any of the holders of our liabilities and/or securities, including our common stock, receiving no distribution on account of their interests and cancellation of their holdings. Moreover, a plan of reorganization can be confirmed, under the Bankruptcy Code, even if the holders of our common stock vote against the plan of reorganization and even if the plan of reorganization provides that the holders of our common stock receive no distribution on account of their equity interests. The accompanying Unaudited Condensed Consolidated Financial Statements do not include any adjustments related to the recoverability and classification of assets or the amounts and classification of liabilities or any other adjustments that might be necessary should the Company be unable to continue as a going concern or as a consequence of the filing of the Chapter 11 Cases. See Note 2 for additional information.

Recently adopted accounting principles
In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (ASC 842). ASC 842 replaces the existing guidance on leasing transactions in ASC 840 and requires lessees to recognize on the balance sheet a lease liability and a right-of-use asset for all leases. ASC 842 also changes the recognition, measurement, and presentation of expense associated with leases and provides clarification regarding the identification of certain components of contracts that would represent a lease. The Company adopted the new standard effective January 1, 2019.


The Company elected the transition methodology provided by ASU No. 2018-11, Leases (Topic 842): Targeted Improvements, whereby it applied the requirements of ASC 842 on a prospective basis as of the adoption date of January 1, 2019, without retrospectively adjusting prior periods. The Company elected to adopt the package of practical expedients provided by ASC 842 that allows prior determinations of whether existing contracts are, or contain, leases and the classification of existing leases to continue without reassessment. The Company elected to keep leases with an initial term of 12 months or less off of the balance sheet. The Company intends to recognize those lease payments in the consolidated statement of operations on a straight-line basis over the lease term. The Company also elected to combined lease and non-lease components in the computations of lease obligations and right-of-use assets. During our evaluation of ASU 2016-02, we concluded that certain of our helicopter service contracts contain a lease component. Our typical helicopter service contracts qualify for a practical expedient, which is available to lessors under certain circumstances, to combine the lease and non-lease components and account for the combined component in accordance with the accounting treatment for the predominant component. We have applied this practical expedient and intend to combine the lease and service components of our revenue contracts and continue to account for the combined component under Topic 606, Revenue from Contracts with Customers.

The Company completed the implementation of an information technology system to track and account for its leases and updated its accounting policies to support the accounting for leases under ASC 842. The Company completed its lease inventory and determined its most significant leases involve aircraft and facilities. In the first quarter 2019, the Company's adoption of ASC 842 resulted in recording on its Condensed Consolidated Balance Sheet lease liabilities of approximately $152.9 million and right-of-use assets of approximately $152.1 million with no material impact on the Company's consolidated statement of operations and consolidated cash flow statement. For additional information, see Note 13.

2. BANKRUPTCY FILING

Chapter 11 Proceedings
On March 14, 2019 (the "Petition Date"), PHI and certain of its four subsidiaries (collectively, the "Debtors") each filed a voluntary petitions (the "Chapter 11 Cases") in the United States Bankruptcy Court for the Northern District of Texas (the "Bankruptcy Court") for relief under Chapter 11 of Title 11 of the United States Code (the "Bankruptcy Code"). The Chapter 11 Cases are being jointly administered under the caption "In re PHI, Inc., et al., Case No. 19-30923."
The Debtors are currently operating their businesses and managing their properties as "debtors in possession" in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court. Certain subsidiaries of PHI (collectively, the "Non-Filing Entities") are not part of the Chapter 11 Cases. The Non-Filing Entities will continue to operate their businesses in the normal course and their results are included in our interim Unaudited Condensed Consolidated Financial Statements.
On April 1, 2019, the Debtors filed with the Bankruptcy Court the Debtors’ Joint Chapter 11 Plan of Reorganization (the “Plan”) and the Disclosure Statement related thereto, the Debtors filed with the Bankruptcy Court the Debtors’ First Amended Joint Chapter 11 Plan of Reorganization and related Disclosure Statement. The Plan is subject to confirmation by the Bankruptcy Court and acceptance by the Debtors’ creditors (as and to the extent required under the Bankruptcy Code). The Plan provides for, among other things, the issuance of shares of new common stock to holders of certain classes of secured and unsecured claims. The Plan contemplates that the Company’s existing equity holders would receive no recovery on account of such equity interests and that the existing voting and non-voting common stock would be cancelled as of the effective date.
The Debtors remain in negotiations with the Company's various stakeholders regarding the terms and conditions of the Plan.
Documents filed on the docket of and other information related to the Chapter 11 Cases are available free of charge online at https://cases.primeclerk.com/PHI. Documents and other information available on such website are not part of this document and shall not be deemed incorporated by reference in this document.

Significant Bankruptcy Court Actions
Following the Petition Date, the Bankruptcy Court entered certain interim and final orders facilitating the Debtors' operational transition into Chapter 11. These orders authorized the Debtors to, among other things, pay employee wages and benefits, and pay vendors and suppliers in the ordinary course for all goods and services provided after the datePetition Date.

Executive Compensation Plans
In connection with the Chapter 11 Cases, the Compensation Committee of the Board of Directors of the Company has adopted on behalf of the Company a Key Employee Incentive Plan (the "KEIP") and a Key Employee Retention Plan ("KERP"), each subject to the approval of the Bankruptcy Court. The KEIP is designed to incentivize seven of the Company's senior executives by providing a total potential cash award pool of approximately $4.2 million at Threshold, $5.6 million at plan and $7.0 million for exceeding plan, and is contingent upon emergence from Chapter 11, achievement of certain financial targets and achievement of certain safety metrics. After certain modifications announced on the record at the hearing on April 29, 2019, the Bankruptcy

Court approved the KEIP, as modified, and subject to the parties agreeing to the final definition of the terms and conditions of the plan. The KERP is designed to enhance retention of up to 61 other non-insider employees and provides a total award pool of approximately $3.5 million cash. The Bankruptcy Court approved the KERP on April 16, 2019.

Financial Reporting in Reorganization
Effective on the Petition Date, the Company began to apply accounting standards applicable to reorganizations, which are applicable to companies under Chapter 11 bankruptcy protection. They require the financial statements for periods subsequent to the Petition Date to distinguish transactions and events that are directly associated with the reorganization from the ongoing operations of the business. Expenses, realized gains and losses, and provisions for losses that are directly associated with reorganization proceedings must be reported separately as reorganization items, net in the Unaudited Condensed Consolidated Statements of Operations. In addition, the balance sheet must distinguish pre-petition liabilities subject to compromise ("LSTC") of the Debtors from pre-petition liabilities that are not subject to compromise, post-petition liabilities, and liabilities of non-Debtor entities in the accompanying Unaudited Condensed Consolidated Balance Sheets. LSTC are pre-petition obligations that are not fully secured and have at least a possibility of not being repaid at the full claim amount. Where there is uncertainty about whether a secured claim will be paid or impaired pursuant to the Chapter 11 Cases, the Company has classified the entire amount of the claim as an outstanding liability.
Furthermore, the realization of assets and the satisfaction of liabilities are subject to uncertainty. While operating as debtors-in- possession, certain claims against the Debtors in existence before the filing of the petitions for relief under the federal bankruptcy laws are stayed while the Debtors continue business operations as debtors in possession. These claims are reflected in the unaudited Condensed Consolidated Balance Sheets at March 31, 2019 as LSTC. Additional LSTC may arise after the filing date resulting from rejection of executory contracts, including leases, and from the determination by the Bankruptcy Court (or agreed to by parties in interest) of allowed claims for contingencies and other disputed amounts. Claims secured against the Debtors' assets (secured claims) also are stayed, although the holders of such claims have the right to move the Bankruptcy Court for relief from the stay. The Company's secured claims are secured primarily by liens on certain of the Debtors’ receivables, inventory and spare parts and certain of their specified aircraft.

Liabilities Subject to Compromise
As a result of the commencement of the Chapter 11 Cases, the payment of pre-petition liabilities is generally subject to compromise pursuant to a plan of reorganization. Generally, actions to enforce or otherwise effect payment of pre-petition liabilities are stayed. Although payment of pre-petition claims generally is not permitted, the Bankruptcy Court granted the Debtors authority to pay certain pre-petition claims in designated categories and subject to certain terms and conditions. This relief generally was designed to preserve the value of the Debtors' business and assets. Among other things, the Bankruptcy Court authorized, but did not require, the Debtors to pay certain pre-petition claims relating to employee wages and benefits, taxes, and certain critical vendors.
Pre-petition liabilities that are subject to compromise are required to be reported at the amounts expected to be allowed by the Bankruptcy Court, even if they may be settled for different amounts. The amounts classified as LSTC may be subject to future adjustments depending on Bankruptcy Court actions, further developments with respect to disputed claims, the determination of secured status of certain claims, the determination as to the value of any collateral securing claims, proof of claims, or other events.
See Note 7 - “Liabilities Subject to Compromise” for a specific discussion on balances subject to compromise.

Process for Plan of Reorganization
As noted above, on April 1, 2019, the Debtors filed the Plan, which if confirmed by the Bankruptcy Court, would, among other things, resolve the Debtors’ prepetition obligations and issue equity for the reorganized Company and establish the reorganized Company’s corporate governance subsequent to exit from bankruptcy.
In addition to being voted on by holders of impaired claims, the Plan must satisfy certain requirements of the Bankruptcy Code and must be approved, or confirmed, by the Bankruptcy Court in order to become effective. The Plan will be accepted by a class of holders of claims against the Debtors if at least one-half in number and two-thirds in dollar amount of claims actually voting in each class of claims impaired by the Plan have voted to accept the Plan. A class of claims or equity interests that does not receive or retain any property under the Plan on account of such claims or interests is deemed to have voted to reject the Plan.
Under certain circumstances set forth in Section 1129(b) of the Bankruptcy Code, the Bankruptcy Court may confirm the Plan even if the Plan has not been accepted by all impaired classes of claims and equity interests. The precise requirements and evidentiary showing for confirming the Plan notwithstanding its rejection by one or more impaired classes of claims or equity interests depends upon a number of factors, including the status and seniority of the claims or equity interests in the rejecting class (i.e., unsecured or secured claims, subordinated or senior claims).

Although the Plan provides that the Debtors will emerge from bankruptcy as a going concern, there can be no assurance at this Quarterly Reporttime that the Debtors will be able to successfully confirm and consummate the Plan or any other alternative restructuring transaction, including a sale of all or substantially all of the Debtors’ assets, that satisfies the conditions of the Bankruptcy Code and is confirmed by the Bankruptcy Court, or that the Plan will be implemented successfully. These conditions raise substantial doubt about the Company's ability to continue as a going concern.

Reorganization Items, Net
Reorganization items, net represent amounts incurred after the Petition Date as a direct result of the Chapter 11 Cases and are filed.
comprised of professional fees for the period from March 15, 2019 through March 31, 2019.

3. INVESTMENTS
We classify all of our short-term investments as available-for-sale. We carry these at fair value and report unrealized gains and losses, net of taxes, in Accumulated other comprehensive loss, which is a separate component of shareholders’ equity in our Condensed Consolidated Balance Sheets. These unrealized gains and losses are also reflected in our Condensed Consolidated Statements of Comprehensive Income and Condensed Consolidated Statements of Shareholders’ Equity. We determine cost, gains, and losses using the specific identification method.
Investments consisted of the following as of March 31, 2019:
  Cost Basis Unrealized

At March 31, 2019 and December 31, 2018, we classified $19.8 million of our aggregate investments as long-term investments and recorded them in our Condensed Consolidated Balance Sheets as restricted cash and investments, as they are securing outstanding letters of credit with maturities beyond one year.

4. VALUATION ACCOUNTS
We establish the amount of our allowance for doubtful accounts based upon factors relating to the credit risk of specific customers, current market conditions, and other information. Our allowance for doubtful accounts was approximately $6.1 million at March 31, 2019, and December 31, 2018, respectively.

Revenues related to flights generated by our Air Medical segment are recorded net of contractual allowances under agreements with third party payors and estimated uncompensated care when the services are provided. The allowance for contractual discounts was $116.5 million and $123.8 million as of March 31, 2019 and December 31, 2018, respectively. The allowance for uncompensated care was $51.6 million and $51.9 million as of March 31, 2019 and December 31, 2018, respectively.
Included in the allowance for uncompensated care listed above is the value of services to patients who are unable to pay when it is determined that they qualify for charity care. The value of these services was $1.9 million and $1.5 million for the quarters ended March 31, 2019 and 2018, respectively. The estimated cost of providing charity services was $0.5 million and $0.4 million for the quarters ended March 31, 2019 and 2018, respectively. The estimated costs of providing charity services are based on a calculation that applies a ratio of costs to the charges for uncompensated charity care. The ratio of costs to charges is based on our Air Medical segment’s total expenses divided by gross patient service revenue.
The allowance for contractual discounts and estimated uncompensated care (expressed as a percentage of gross segment accounts receivable) as of the dates listed below was as follows: 
  March 31, 2019 December 31, 2018
Allowance for Contractual Discounts 50% 51%
Allowance for Uncompensated Care 22% 22%
We have also established valuation reserves related to obsolete and slow-moving spare parts inventory. The inventory valuation reserves were $18.4 million and $17.9 million at March 31, 2019 and December 31, 2018, respectively.

5. FAIR VALUE MEASUREMENTS
Accounting standards require that assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories:
Level 1: Quoted market prices in active markets for identical assets or liabilities.
Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data.
Level 3: Unobservable inputs that are not corroborated by market data.











The following table summarizes the valuation of our investments and financial instruments by the above pricing levels as of the valuation dates listed:
  March 31, 2019
  Total (Level 1) (Level 2)
  (Thousands of dollars)
Investments:      
Money market mutual funds $85,412

We hold our short-term investments in an investment fund consisting of high quality money market instruments of governmental and private issuers, which is classified as a short-term investment. Level 1 inputs are quoted prices (unadjusted) for identical assets or liabilities in active markets. These items are traded with sufficient frequency and volume to provide pricing on an ongoing basis. The fair values of the investments in these funds are based on observable market prices, and therefore, have been categorized in Level 1 in the fair value hierarchy. Level 2 inputs reflect quoted prices for identical assets or liabilities that are not actively traded. These items may not be traded daily; examples include commercial paper, corporate bonds and U.S. government agencies debt. There have been no reclassifications of assets between Level 1 and Level 2 investments during the periods covered by the financial statements included in this report. We hold no Level 2 or Level 3 investments.
Cash, accounts receivable, accounts payable and accrued liabilities, and term loan debt all had fair values approximating their carrying amounts at March 31, 2019 and December 31, 2018. We determine the estimated fair value of our 5.25% Senior Notes due 2019 (the "Senior Notes") using Level 2 inputs, including quoted market indications of similar publicly-traded debt. The fair value of our 5.25% Senior Notes due 2019, based on quoted market prices, was $313.2 million and $344.2 million at March 31, 2019 and December 31, 2018, respectively. We provide no assurances, however, that the ultimate recovery of the holders of these notes pursuant to the Chapter 11 Cases will correspond to these fair values as of these prior dates.

6. DEBT
Listed below is information regarding our indebtedness. All indebtedness owed under our Senior Notes as of March 31, 2019 is classified as subject to compromise, and as of December 31, 2018 was classified as short-term debt on our balance sheet. The Thirty-Two, LLC and Blue Torch term loans are classified as long-term debt as of March 31, 2019, except for the amount due within the next twelve months.

Senior Notes - Subject to the automatic stay of the Bankruptcy Code, our 5.25% Senior Notes (the “Senior Notes”) matured on March 15, 2019. These notes are unconditionally guaranteed on a senior basis by each of PHI, Inc.’s wholly-owned domestic subsidiaries. These notes and related guarantees are the general, unsecured obligations of PHI, Inc. and the guarantors. For more information regarding the impact of our bankruptcy proceedings on the Senior Notes, see Note 2.

Recently Adopted Accounting PronouncementsBlue Torch Term Loan Agreement - On March 13, 2019, we entered into a Loan Agreement, dated the same date (the “Term Loan Agreement”), by and among the Company, as borrower, certain of our subsidiaries as guarantors party thereto, the lenders from time to time party thereto, and Blue Torch Finance, LLC, as administrative agent and collateral agent, for a first lien term loan of up to $70 million (the “Term Loan”). Immediately upon entering into the Term Loan Agreement, and prior to the filing of the Chapter 11 Cases, we borrowed $70 million thereunder, the net proceeds of which (after the payment of transaction expenses and fees thereunder) are expected to be used to continue to fund the working capital and liquidity requirements of the Company during the pendency of the Chapter 11 Cases and thereafter. For additional information regarding our Chapter 11 Cases, see Notes 2 and 7 herein and Notes 1 and 19 on our filed 2018 10-K.

The full principal amount of the Term Loan is due March 13, 2023. At our election, borrowings under the Term Loan bear interest at either the LIBOR Rate (as defined in the Term Loan Agreement) plus 6% or the Base Rate (as defined in the Term Loan Agreement) plus 5%. The Term Loan is secured by a first lien on 91 aircraft registered and located in Antarctica, Australia, Canada, and the United States (which are currently deployed primarily in our oil and gas and technical services operations), the related spare parts for such aircraft, and certain other non-working capital assets, as well as a second lien on all working capital assets (second in priority to the liens granted under our below-described term loan agreement, dated as of September 28, 2018, with Thirty Two, L.L.C.). The Term Loan Agreement contains customary pre-payment requirements. In addition, we paid on March 13, 2019 a funding fee, which is subject to forgiveness based on certain future events.

The Term Loan Agreement contains certain customary negative covenants that, among other things, restrict, subject to certain exceptions, the Company’s and each guarantor’s incurrence of additional indebtedness or liens, mergers, dispositions of assets, investments, restricted payments, modifications to material agreements, sale and leasebacks, transactions with affiliates, fundamental changes, locations of certain aircraft and acquisitions of assets. In addition, the financial covenants under the Term Loan Agreement require us to maintain (a) minimum liquidity of the Company, the guarantors and their respective subsidiaries, as of the last day of any calendar month, of at least $20 million of unrestricted cash and cash equivalents (provided that at least $10 million of such cash and cash equivalents shall, as of any date of determination, be held solely by the Company and the guarantors); (b) a minimum fixed charge coverage ratio, as of the last day of the following test periods, commencing with the first full fiscal quarter following the effective date of the plan of reorganization in the Chapter 11 Cases, of at least (i) 0.0000:1.00 for quarters ending on or prior to March 31, 2020, (ii) 0.1875:1.00 for quarters ending from June 30, 2020 through September 30, 2020, (iii) 0.3750:1.00 for quarters ending from December 31, 2020 through March 31, 2021, (iv) 0.9125:1.00 for quarters ending from June 30, 2021 through September 30, 2021, and (v) 1.2000:1.00 for quarters ending on December 31, 2021 and thereafter; (c) a secured leverage ratio, as of the last day of each of the following test periods, commencing with the first full fiscal quarter ending following the effective date of the plan of reorganization in the Chapter 11 Cases (as defined below), of no greater than (i) 4.50:1.00 on or prior to September 30, 2020, (ii) 4.25:1.00 from December 31, 2020 through September 30, 2021, (iii) 4.00:1.00 from December 31, 2021 through December 30, 2022 and (iv) 3.75:1.00 on December 31, 2022 and thereafter; and (d) a total appraisal ratio of the aircraft collateral (less dispositions permitted under the Term Loan Agreement) to borrowings outstanding

under the Term Loan, as of the last day of any calendar month, of at least 4.00:1.00. The Term Loan Agreement also contains customary affirmative covenants and customary representations and warranties. As of the date of these financial statements, we are in compliance with these covenants.

The Term Loan Agreement specifies certain customary events of default, including, among others, failure to pay principal or interest on the Term Loan when due, the breach of representations or warranties in any material respect, non-performance of other covenants and obligations, judgments in excess of $2.5 million, the occurrence of certain ERISA events resulting in liability in excess of $2.5 million, impairments of more than $2.5 million of the collateral securing the Term Loan, and certain change of control events. The filings of the Chapter 11 Cases neither constituted an event of default nor accelerated payment of the Company’s indebtedness under the Term Loan Agreement.

Related Party Term Loan - On September 28, 2018, we entered into a term loan agreement with Thirty Two L.L.C., which provided us with a term loan of $130 million maturing on September 28, 2020. This loan bears interest at an annual fixed rate of 6% payable quarterly, with all principal due on maturity. Thirty Two L.L.C., an entity wholly-owned by our CEO and controlling shareholder, is a related party.
Contemporaneously with borrowing $130.0 million under the term loan, we applied approximately $122.7 million of the loan proceeds to repay principal and accrued interest under our senior secured revolving credit facility, which was terminated in connection with such repayment, and applied the remainder of the proceeds to cash to collateralize certain outstanding letters of credit.
Obligations under the term loan are guaranteed by PHI Air Medical, L.L.C. and PHI Tech Services, Inc., both of which are wholly-owned by us. Our obligations and the guarantors’ obligations are secured by all of their respective inventory, spare parts and accounts receivable located in the U.S.
The related party term loan agreement contains customary restrictive covenants that, subject to certain exceptions and limitations, limit or restrict our ability to, among other things, (i) purchase, retire or redeem any shares of our capital stock; (ii) incur indebtedness; (iii) mortgage or encumber our assets; (iv) make loans to, or guarantee the indebtedness of, any individual or entity; (v) effect a change of control of PHI; (vi) consolidate with or merge into any other corporation, or permit any other corporation to merge into us; (vii) sell or lease all or substantially all of our assets; or (viii) acquire all or a substantial part of the assets or capital stock of another entity. The term loan agreement contains no financial covenants. The term loan agreement contains customary representations and warranties, affirmative covenants and events of default.
Letter of Credit - At March 31, 2019, we had $19.8 million of outstanding letters of credit secured by a like amount of restricted cash, $12.2 million of which secured certain domestic operations or insurance policies and $7.6 million of which guaranteed our performance under an international contract. At December 31, 2018, we had $19.8 million of outstanding letters of credit issued for the same purposes.
Other - PHI, Inc. has cash management arrangements with certain of its principal subsidiaries, in which substantial portions of the subsidiaries’ cash is regularly advanced to PHI, Inc. Although PHI, Inc. periodically repays these advances to fund the subsidiaries’ cash requirements throughout the year, at any given point in time PHI, Inc. may owe a substantial sum to its subsidiaries under these advances, which, in accordance with GAAP, are eliminated in consolidation and therefore not recognized on our consolidated balance sheets. For additional information, see Note 15.

Acceleration of Certain Debt Obligations - The commencement of the Chapter 11 Cases constituted an event of default that accelerated the obligations under the indenture governing our 5.25% Senior Notes due 2019 and our term loan agreement with Thirty Two, L.L.C. Any efforts to enforce payment of such financial obligations under such instruments and agreements are automatically stayed as a result of the Chapter 11 Cases and the holders’ rights of enforcement in respect of such financial obligations are subject to the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court.


7. LIABILITIES SUBJECT TO COMPROMISE
As a result of the filing of the Chapter 11 Cases on March 14, 2019, we have classified unsecured pre-petition liabilities that are expected to be impaired pursuant to the Plan as liabilities subject to compromise in our Condensed Consolidated Balance Sheet at March 31, 2019. Pre-petition liabilities that are subject to compromise are required to be reported at the amounts expected to be allowed, even if they may be settled for lesser amounts. If there was uncertainty at the time of determination about whether a secured claim was under-secured or would be impaired under the Plan, we reflected the entire amount of the claim as an outstanding

liability. The amounts classified at March 31, 2019 as liabilities subject to compromise represent the Company’s estimate as of the filing date of this report of claims as of March 31, 2019 expected to be allowed under the Plan.
The Company’s obligations under the Senior Notes have been affected by the bankruptcy filing. As such, the outstanding balance of these Senior Notes and related accrued pre-petition interest have been classified as liabilities subject to compromise in the condensed consolidated balance sheet as of March 31, 2019.
Generally, actions to enforce or otherwise effect payment of pre-bankruptcy filing liabilities have been stayed during the pendency of the Chapter 11 Cases. Although payment of pre-petition claims is generally not permitted, the Bankruptcy Court approved the Debtors’ “first day” motions allowing, among other things, the Company to pay prepetition employee wages and benefits without interruption, maintain its insurance programs, utilize its current cash management system, and pay undisputed prepetition obligations owed to its vendors and trade creditors in the ordinary course of business. As a result of this approval, the Company continues to pay certain pre-petition claims in designated categories and subject to certain terms and conditions in the ordinary course of business, and we have not classified these liabilities as subject to compromise in the Condensed Consolidated Balance Sheet as of March 31, 2019. With respect to pre-petition claims, the Company notified all known claimants of the deadline to file a proof of claim with the Court.
The Company has been paying and intends to continue to pay post-petition claims in the ordinary course of business.
The following table reflects pre-petition liabilities that are subject to compromise included in our Condensed Consolidated Balance Sheet as of March 31, 2019. See Note 6 - “Debt” for further information on our Senior Notes and related balances subject to compromise:

  March 31, 2019
  (Thousands of dollars)
Senior Notes issued March 17, 2014, interest only payable semi-annually at 5.25%, matured March 15, 2019 $500,000
Accrued interest payable 13,125
Total liabilities subject to compromise $513,125



8. EARNINGS PER SHARE
The components of basic and diluted earnings per share for the quarter and three months ended March 31, 2019 and 2018 are as follows: 
  Quarter Ended

(1)For the quarters ended March 31, 2019 and 2018, 1,343,753 and 490,843 unvested restricted stock units were excluded from the weighted average outstanding shares of common stock, diluted, respectively, as they were anti-dilutive to earnings per share.


9. STOCK-BASED COMPENSATION
We recognize the cost of employee compensation received in the form of equity instruments based on the grant date fair value of those awards. The table below sets forth the total amount of stock-based compensation expense for the quarters ended March 31, 2019 and 2018.
  Quarter Ended

Total stock-based compensation expense $1,315
 $1,319
 
During the quarter ended March 31, 2019, no time-based restricted units or performance units were awarded to managerial employees.

On February 20, 2019, the PHI Compensation Committee approved the vesting of the 2017 performance RSUs based on the Company’s financial results exceeding the pre-determined business performance metrics set in 2017 for the two year performance period (January 1, 2017 - December 31, 2018). The PHI Compensation Committee decided to settle these vested RSU awards in cash based upon the closing market price on February 20, 2019, the date of the committee's certification that the performance metrics were met ($2.21 per share). The total amount of cash paid was $0.8 million. On February 20, 2019, the Compensation Committee certified that the performance metrics for performance-based restricted stock units granted in 2016 had not been met, which resulted in the forfeiture of 667,238 of such RSUs.
10. ASSET DISPOSALS
There were no sales or disposals of aircraft during the first quarter of 2019. We had an immaterial amount of non-aircraft disposals during the first quarter of 2019.
During the first quarter of 2018, we disposed of one light aircraft previously utilized in the Air Medical segment and donated to a charitable organization one aircraft previously used in our Oil and Gas segment. These aircraft no longer met our strategic needs. Cash proceeds from the sale totaled $0.8 million, resulting in a $0.9 million loss on the disposal of these assets.
11. COMMITMENTS AND CONTINGENCIES
Commitments We currently have no aircraft purchase commitments.
Environmental Matters – We have recorded an estimated liability of $0.15 million as of March 31, 2019 for environmental response costs. Previously, we conducted environmental surveys of our former Lafayette Facility located at the Lafayette Regional Airport, which we vacated in 2001, and determined that limited soil and groundwater contamination exist at two parcels of land at the former facility. An Assessment Report for both parcels was submitted in 2003 (and updated in 2006) to the Louisiana Department of Environmental Quality ("LDEQ") and the Louisiana Department of Natural Resources ("LDNR"). Approvals for the Assessment Report were received from the LDEQ and LDNR in 2010 and 2011, respectively. Since that time, we have performed groundwater sampling of the required groundwater monitor well installations at both parcels and submitted these sampling reports to the LDEQ. Pursuant to an agreement with the LDEQ, we provided groundwater sample results semi-annually to the LDEQ for both parcels from 2005 to 2015. The LDEQ approved a reduction in the sampling program from semi-annual to annual groundwater monitoring in 2015. Based on our working relationship and agreements with the LDEQ, and the results of ongoing former facility parcel monitoring, we believe that ultimate remediation costs for the subject parcels will not be material to our consolidated financial position, operations or cash flows.
Legal Matters – From time to time, we are involved in various legal actions incidental to our business, including actions relating to employee claims, medical malpractice claims, tax issues, grievance hearings before labor regulatory agencies, and miscellaneous third party tort actions. The outcome of these proceedings is not predictable. However, based on current circumstances, we do not believe that the ultimate resolution of our presently pending proceedings, after considering available defenses and any insurance coverage or indemnification rights, will have a material adverse effect on our financial position, results of operations or cash flows.
Notwithstanding the foregoing, any litigation pending against us or any of the Debtors as of the Petition Date and any claims that could be asserted against us or an of the Debtors that arose prior to the Petition Date are automatically stayed as a result of the

commencement of the Chapter 11 Cases pursuant to the section 362(2) of the Bankruptcy Code, subject to certain statutory exceptions. These matters will be subject to resolution in accordance with the Bankruptcy Code and applicable orders of the Bankruptcy Court.

12. REVENUE RECOGNITION
In 2014, the Financial Accounting Standard Board ("the FASB") issued ASC 606, Revenue from Contracts with Customers (“ASC 606”), replacing the existing accounting standard and industry specific guidance for revenue recognition with a five-step model for recognizing and measuring revenue from contracts with customers. The underlying principle of the new standard is to recognize revenue to depict the transfer of goods or services to customers at the amount expected to be collected. ASC 606 became effective on January 1, 2018 and the Companywe adopted it using the modified retrospective method applied to open contracts and only to the version of the contracts in effect as of January 1, 2018. Prior period amounts have not been adjusted and continue to be reflected in accordance with the Company’s historical accounting.  There was no impact on the condensed consolidated financial statements and no cumulative effect adjustment was recognized.
In general, under ASC 606, we recognize revenue when a service or good is sold to a customer and there is a contract.contract exists. 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 has been transferred to the customer, the transaction price has been determined and allocated to the performed performance obligations and we have determined that collection has occurred or is probable of occurring.
The Company measures revenue as the amount of consideration we expectTaxes billed to receive in exchange of the services provided. Taxesand collected from customers and remitted to governmental authorities and revenues are reported as revenue on a net basis in the Company’sour financial statements. Thus, the Company excludeswe exclude taxes imposed onbilled to 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.
Revenue Recognition Oil & Gas Revenue Recognition - The Company providesWe provide helicopter services to oil and gas customers operating in the Gulf of Mexico and a number of foreign countries. Revenues are recognized when performance obligations are satisfied over time in accordance with contractual terms, in an amount that reflects the consideration the Company expects to be entitled to in exchange for services rendered.  
Air Medical Revenue Recognition Air Medical - The Company providesWe provide helicopter services to hospitals and emergency service providers in several U.S. states, and individuals,or to individual patients in the U.S. in which case the Company iswe are paid by either a commercial insurance company, federal or state agency, or the patient. Our Air Medical segment operates primarily under the independent provider model and, to a lesser extent, under the traditional provider model. Revenues related to the independent provider model services are recorded in the period in which we satisfy our performance obligations under contracts by providing our services to our customers based upon established billing rates net of contractual allowances under agreements with third party payors and net of uncompensated care allowances. These amounts are due from patients, third-party payors (including health insurers and government programs), and others and includes variable consideration for retroactive revenue adjustments due to settlement of audits, reviews, and investigations.

Generally, the Company billswe bill the patients and third-party payors several days after the services are performed. Revenues generated under the traditional provider model are recognized as performance obligations are satisfied over time in accordance with contractual terms, in an amount that reflects the consideration the Company expects to be entitled in exchange for services rendered.
Performance Obligations Oil & Gas Performance Obligations - A performance obligation arises under contracts with customers to render services and is the unit of account under ASC 606.  Operating revenue from our Oil and Gas segment is derived mainly from fixed-term contracts with our customers, a substantial portion of which are competitively bid. A small portion of our Oil and Gas segment 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 on relatively short notice by the customers), with payment in U.S. dollars. The Company accounts. We account for services rendered separately if they are distinct and the services are 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. 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. The nature of our variable charges within our flight services contracts are not effective until a customer-initiated flight order and the actual hours flown are

determined; therefore, the associated flight revenue generally cannot be reasonably and reliably estimated before hand. A contract’s standalone selling prices are determined based upon the prices that the Company chargeswe charge for itsour services rendered.  The majority of the Company’sour 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.  The CompanyWe typically invoicesinvoice customers on a monthly basis with the term between invoicing and when the payment is due typically being between 30 and 60 days.
Air Medical Performance Obligations Air Medical - Performance obligations are determined based upon the nature of the services provided. Under the independent provider model, we measure the performance obligation from the moment the patient is loaded into the aircraft until it reaches its destination. Under this model, we have no fixed revenue stream and compete for transport referrals on a daily basis with other independent operators in the area. Under the traditional provider model, we contract directly with the customer to provide their transportation services. These contracts are typically awarded or renewed through competitive bidding and typically permit early termination by the customer on relatively short notice. As a traditional provider, we typically bill a fixed monthly rate for aircraft availability and an hourly rate for flight time. For each of these types of helicopter services, we have determined that each has a single distinct performance obligation. Traditional provider models services include 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. The variable charges within such contracts are not effective until the customer initiates a flight order and the actual hours flown are determined; therefore, the associated revenue generally cannot be reasonably and reliably estimated beforehand. For the traditional provider model, we determine the transaction price based upon standard charges for goods and services provided.
As an independent provider, we bill for our services on the basis of a flat rate plus a variable charge per patient-loaded mile, regardless of aircraft model, and are typically compensated by private insurance, Medicaid or Medicare, or directly by transported patients who self-pay. We recognize revenues for performance obligations satisfied at a point in time, which generally relate to patients receiving air medical services when: (1) services are provided; and (2) we do not believe the patient requires additional services. For the independent provider model, we determine the transaction price based upon gross charges for services provided reduced by contractual adjustments provided to third-party payors, discounts provided to uninsured patients in accordance with Company policy, and/or implicit price concessions provided to uninsured patients. We determine estimates of contractual adjustments and discounts based upon contractual agreements, our discount policy, and historical experience. We determine our estimate of implicit price concessions based upon our historical collection experience with these classes of patients using a portfolio approach as a practical expedient to account for patient contracts as collective groups, rather than individually. The financial statement effects of using this practical expedient are not materially different from an individual contract approach.
Under the traditional provider model, we contract directly with the customer to provide their transportation services, with the contracts typically awarded or renewed through competitive bidding. As a traditional provider, we typically bill a fixed monthly rate for aircraft availability and an hourly rate for flight time. For each of these types of helicopter services, we have determined that each has a single distinct performance obligation. Traditional provider models services include 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. The variable charges within the contracts are not effective until the customer initiates a flight order and the actual hours flown are determined; therefore, the associated revenue generally cannot be reasonably and reliably estimated beforehand. For the traditional provider model, we determine the transaction price based upon standard charges for goods and services provided.

As further described in Note 3, independent provider revenues are recorded net ofWe estimate contractual allowances under agreements with third party payors and estimated uncompensated care at the time the services are provided. Contractual allowances and uncompensated care are estimated based on historical collection experience by payor category (consisting mainly ofcategory. The main payor categories are Medicaid, Medicare, private insurance, Medicaid, Medicare, and self-pay).self-pay. Changes in payor mix, reimbursement rates and uncompensated care rates are the factors most subject to sensitivity and variability in calculating our allowances. We compute a historical payment analysis of accounts by category. The allowance percentages calculated are applied to the payor categories, and the necessary adjustments are made to the revenue allowance. Agreements with third-party payors typically provideIn our Air Medical Segment, the allowance for payments atcontractual discounts against outstanding accounts receivable was $116.5 million, and $123.8 million as of March 31, 2019, and December 31, 2018, respectively, and the allowance for uncompensated care against outstanding accounts receivable was $51.6 million, and $51.9 million as of March 31, 2019 and December 31, 2018, respectively. Included in the allowance for uncompensated care above is the value of services to patients who are unable to pay when it is determined that they qualify as charity care. The value of these services was $1.9 million, and $1.5 million for the quarter ended on March 31, 2019 and 2018, respectively. The estimated cost of providing charity services was $0.5 million, and $0.4 million for the quarter ended March 31, 2019, and 2018, respectively. The estimated costs of providing charity services are based on a calculation that applies a ratio of costs to the charges for uncompensated charity care. The ratio of costs to charges is based on the Air Medical independent provider model’s total expenses divided by gross patient service revenue.

In determining the allowance estimates for our Air Medical segment’s billing, receivables and revenue, we utilize the prior twelve months’ payment history and current trends in payor behavior by each separate payor group, which we evaluate on a state by state basis. A percentage of amounts less than established charges.

collected compared to the total invoice is determined from this process and applied to the current month’s billings and receivables. If a receivable related to the self-pay category is outstanding twelve months or greater, we record a reserve equal to 100% of the receivable. Receivables related to other payor categories are scrutinized when they are outstanding for nine months or longer and additional allowances are recorded if warranted.

As of June 30, 3018March 31, 2019 and December 31, 2017,2018, net receivables related to our (i) Oil and Gas segment were $110.1$75.8 million and $106.8$74.1 million, (ii) Air Medical segment were $82.7$90.4 million and $74.4$90.2 million and (iii) Technical Services segment were $1.5$3.1 million and $4.8$4.1 million, respectively. Contract assets and contract liabilities were immaterial as of June 30, 2018. Our contracts typically include termination clauses that allow both parties to terminate existing contracts with a 30 to 180 day notice period.

The CompanyWe generally hashave a right to consideration in an amount that corresponds directly with the value to the customer of the entity's
performance completed to date and may recognize revenue in the amount to which the entity has a right to invoice. We have elected to use the invoice practical expedient for revenue recognized when performance obligations are satisfied over time. In addition, payment for goods and services rendered is typically due in the subsequent month following satisfaction of the Company’sour performance obligation. Our contracts typically include termination clauses that allow both parties to terminate existing contracts with a 30 to 180 day notice period.

TheOur Technical Services segment - provides helicopter flight services and helicopter repair and overhaul services for existing flight operations customers that own their own aircraft. Under this segment, the Companywe periodically providesprovide certain services to governmental customers, including the Company’sour agreement to operate six aircraft for the National Science Foundation in Antarctica. Under this segment, we also offer certain software as a service to our Oil and Gas customers. Revenues are recognized when performance obligations are satisfied in accordance with contractual terms, in an amount that reflects the consideration the Company expectswe expect to be entitled to in exchange for services rendered.   For these helicopter services, we determined that each has a single distinct performance obligation.

On January 26, 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (ASU 2017-04). ASU 2017-04 removes the requirement to compare the implied fair value of goodwill with the carrying amount as part of Step 2 of the goodwill impairment test. Under the new standard, the goodwill impairment loss will be measured as the excess of a reporting unit's carrying amount over its fair value, not exceeding the total amount of goodwill allocated to that reporting unit, which may increase the frequency of goodwill impairment charges if a future goodwill impairment test does not pass the Step 1 evaluation. ASU 2017-04 is effective prospectively for periods beginning on or after December 15, 2019, with early adoption permitted. The Company adopted ASU 2017-04 effective January 1, 2018. The Company will perform goodwill impairment testing under the new standard annually as of October 1st or when events or changes in circumstances indicate that a potential impairment exist.

In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes, which requires that deferred tax assets and liabilities be classified as noncurrent in a classified balance sheet. PHI, Inc. adopted this ASU in the fourth quarter of 2017 on a prospective basis. Beginning with the December 31, 2017 balances, all deferred taxes were classified as non-current. Periods prior to December 31, 2017 were not retrospectively adjusted.

In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other than Inventory, which will require an entity to recognize the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. The ASU is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. The Company adopted ASU 2016-16 effective January 1, 2018 with no material impact to the condensed consolidated financial statements.

In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. ASU 2017-01 clarifies the definition of a business and requires that an entity apply certain criteria in order to determine when a set of assets and activities qualifies as a business. The adoption of this standard is expected to result in fewer acquisitions of properties qualifying as acquisitions of businesses and, accordingly, acquisition costs for those acquisitions that do not qualify as businesses will be capitalized rather than expensed. This standard is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years, and should be applied on a prospective basis. The Company adopted ASU 2017-01 effective January 1, 2018 with no material impact to the condensed consolidated financial statements.

On December 22, 2017, the Tax Cuts and Jobs Act (the “Tax Act”) was enacted which significantly reformed the U.S. Internal Revenue Code (the “Code”). The Tax Act, among other things, reduced the federal corporate income tax rate from 35% to 21% effective January 1, 2018. Following the enactment of the Tax Act, the SEC staff issued Staff Accounting Bulletin 118 - "Income Tax Accounting Implications of the Tax Cuts and Jobs Act" (SAB 118), which provides for a measurement period of up to one year from the enactment date to complete accounting under GAAP for the tax effects of the legislation. As of December 31, 2017, the Company had not completed its accounting for the tax effects of the Tax Act. However, the Company remeasured its net deferred tax liability at December 31, 2017 and provisionally recognized a net benefit of $49.2 million in its consolidated statement of operations for the year ended December 31, 2017.  As of June 30, 2018, the Company has not completed its accounting for the tax effects of the Tax Act. The Company is still analyzing certain aspects of the Tax Act and refining its calculations, which could potentially affect the measurement of these balances or potentially give rise to changes to its current provisional estimates.  The Company’s estimates may be affected by a wide variety of factors, including additional regulatory guidance issued with respect to the Tax Act.  Any adjustments to the provisional amounts will be recognized as a component of income tax in the period in which the adjustments are determined. We expect to complete the accounting by the time we file our 2017 U.S. corporate income tax return in the 3rd quarter of 2018.
New Accounting Pronouncements - In February 2016, the FASB issued ASU 2016-02, Leases, which replaces the existing guidance on leasing transactions in ASC 840 to require recognition of the assets and liabilities for the rights and obligations created by those leases on the balance sheet. The Company has formed an implementation team that is inventorying leases under ASC 840 and contracts which may be leases under ASC 842, and evaluating the impact that adoption of this guidance will have on the Company’s financial statements, which includes monitoring industry specific developments including recent exposure drafts issued by the FASB. Based on our lease portfolio as of June 30, 2018, we expect the adoption of this standard will result in a material change to our consolidated assets and liabilities. We plan to adopt this standard beginning January 1, 2019.
2. INVESTMENTS
We classify all of our short-term investments as available-for-sale. We carry these at fair value and report unrealized gains and losses, net of taxes, in Accumulated other comprehensive loss, which is a separate component of shareholders’ equity in our Condensed Consolidated Balance Sheets. These unrealized gains and losses are also reflected in our Condensed Consolidated Statements of Comprehensive Income and Condensed Consolidated Statements of Shareholders’ Equity. We determine cost, gains, and losses using the specific identification method.

From time to time over the periods covered in our financial statements included herein (and as illustrated in the foregoing tables), our investments have experienced net unrealized losses. We consider these declines in market value to be due to customary market fluctuations, and we typically do not plan to sell these investments prior to maturity. For these reasons, we do not consider any of our investments to be other than temporarily impaired at June 30, 2018 or December 31, 2017. For additional information regarding our criteria for making these assessments, see Note 2 to the financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2017.

3. VALUATION ACCOUNTS
We establish the amount of our allowance for doubtful accounts based upon factors relating to the credit risk of specific customers, current market conditions, and other information. Our allowance for doubtful accounts was approximately $7.3 million and $7.2 million at June 30, 2018, and December 31, 2017, respectively.

Revenues related to flights generated by our Air Medical segment are recorded net of contractual allowances under agreements with third party payors and estimated uncompensated care when the services are provided. The allowance for contractual discounts was $118.4 million and $117.8 million as of June 30, 2018 and December 31, 2017, respectively. The allowance for uncompensated care was $59.6 million and $52.5 million as of June 30, 2018 and December 31, 2017, respectively.
Included in the allowance for uncompensated care listed above is the value of services to patients who are unable to pay when it is determined that they qualify for charity care. The value of these services was $1.7 million and $2.0 million for the quarters ended June 30, 2018 and 2017, respectively. The value of these services was $3.3 million and $4.4 million for the six months ended June 30, 2018 and 2017, respectively. The estimated cost of providing charity services was $0.4 million for the quarters ended June 30, 2018 and 2017. The estimated cost of providing charity services was $0.8 million and $1.0 million for the six months ended June 30, 2018 and 2017, respectively. The estimated costs of providing charity services are based on a calculation that applies a ratio of costs to the charges for uncompensated charity care. The ratio of costs to charges is based on our Air Medical segment’s total expenses divided by gross patient service revenue.
The allowance for contractual discounts and estimated uncompensated care (expressed as a percentage of gross segment accounts receivable) as of the dates listed below was as follows: 
  June 30, 2018 December 31, 2017
Allowance for Contractual Discounts 50% 53%
Allowance for Uncompensated Care 25% 24%
We have also established valuation reserves related to obsolete and slow-moving spare parts inventory. The inventory valuation reserves were $22.7 million and $20.9 million at June 30, 2018 and December 31, 2017, respectively.
4. FAIR VALUE MEASUREMENTS
Accounting standards require that assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories:
Level 1: Quoted market prices in active markets for identical assets or liabilities.
Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data.
Level 3: Unobservable inputs that are not corroborated by market data.










The following table summarizes the valuation of our investments and financial instruments by the above pricing levels as of the valuation dates listed:

We hold our short-term investments in an investment fund consisting of high quality money market instruments of governmental and private issuers, which is classified as a short-term investment. Level 1 inputs are quoted prices (unadjusted) for identical assets or liabilities in active markets. These items are traded with sufficient frequency and volume to provide pricing on an ongoing basis. The fair values of the investments in these funds are based on observable market prices, and therefore, have been categorized in Level 1 in the fair value hierarchy. Level 2 inputs reflect quoted prices for identical assets or liabilities that are not actively traded. These items may not be traded daily; examples include commercial paper, corporate bonds and U.S. government agencies debt. There have been no reclassifications of assets between Level 1 and Level 2 investments during the periods covered by the financial statements included in this report. We hold no Level 3 investments. Investments reflected on our balance sheets as Other Assets, which we hold to fund liabilities under our Officers’ Deferred Compensation Plan, consist mainly of multiple investment funds that are highly liquid and diversified.
Cash, accounts receivable, accounts payable and accrued liabilities, and our revolving credit facility debt all had fair values approximating their carrying amounts at June 30, 2018 and December 31, 2017. Our determination of the estimated fair value of our 5.25% Senior Notes due 2019 is derived using Level 2 inputs, including quoted market indications of similar publicly-traded debt. The fair value of our 5.25% Senior Notes due 2019, based on quoted market prices, was $490.0 million and $499.2 million at June 30, 2018 and December 31, 2017, respectively.

5. DEBT
Listed below is information regarding our indebtedness, all of which was classified as short-term debt on our balance sheet as of June 30, 2018 and as long-term debt on our balance sheet as of December 31, 2017:

Senior Notes - Our 5.25% Senior Notes (the “2019 Notes”) will mature on March 15, 2019, are unconditionally guaranteed on a senior basis by each of PHI, Inc.’s wholly-owned domestic subsidiaries, and are the general, unsecured obligations of PHI, Inc. and the guarantors. Interest is payable semi-annually on March 15 and September 15 of each year. PHI has the option to redeem some or all of the 2019 Notes at any time on or after March 15, 2018 at par plus accrued interest. The indenture governing the 2019 Notes (the “2019 Indenture”) contains, among other things, certain restrictive covenants, including limitations on incurring indebtedness, creating liens, selling assets and entering into certain transactions with affiliates. The covenants also limit PHI’s ability to, among other things, pay cash dividends on common stock, repurchase or redeem common or preferred equity, prepay subordinated debt and make certain investments. Upon the occurrence of a “Change in Control Repurchase Event” (as defined in the 2019 Indenture), PHI will be required, unless it has previously elected to redeem the 2019 Notes as described above, to make an offer to purchase the 2019 Notes for a cash price equal to 101% of their principal amount.
Revolving Credit Facility – Our amended and restated revolving credit facility (our “revolving credit facility”) matures on March 7, 2019. Under this facility, we can borrow up to $130.0 million at floating interest rates based on either the London Interbank Offered Rate plus 275 basis points or the prime rate (each as defined in this facility), at our option. This facility includes usual and customary covenants and events of default for credit facilities of its type. Our ability to borrow under this facility is conditioned upon our continued compliance with such covenants, including, among others, (i) covenants that restrict our ability to engage in certain asset sales, mergers or other fundamental changes, to incur liens or to engage in certain other transactions or activities and (ii) financial covenants that stipulate that PHI will maintain a consolidated working capital ratio of at least 2 to 1, a net funded debt to consolidated net worth ratio not greater than 1.5 to 1, a fixed charge coverage ratio of at least 1 to 1 if our short term investments fall below $150.0 million, and consolidated net worth of at least $500.0 million (with all such terms or amounts as defined in or determined under this facility). Borrowings under our revolving credit facility are secured on a first-priority basis by our inventory, spare parts and accounts receivable.
Effective as of June 30, 2018, we once again received a waiver of our consolidated working capital ratio for the quarter then ended. As of June 30, 2018, we were in compliance with the remaining covenants. For information about other recent amendments or waivers relating to our revolving credit facility, see "Management Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources."
Letter of Credit Facility - We maintain a separate letter of credit facility that had $12.1 million in letters of credit outstanding at June 30, 2018 and $12.4 million at December 31, 2017. We have letters of credit securing our workers compensation policies and a traditional provider contract.
We also have outstanding a letters of credit for $7.7 million issued under our $130.0 million credit facility that reduces the amount we can borrow under that facility. The letters of credit were issued to guaranty our performance under an international contract that was awarded in late 2017 and an air medical license.
Other - PHI, Inc. has cash management arrangements with certain of its principal subsidiaries, in which substantial portions of the subsidiaries’ cash is regularly advanced to PHI, Inc. Although PHI, Inc. periodically repays these advances to fund the subsidiaries’ cash requirements throughout the year, at any given point in time PHI, Inc. may owe a substantial sum to its subsidiaries under these advances, which, in accordance with GAAP, are eliminated in consolidation and therefore not recognized on our consolidated balance sheets. For additional information, see Note 15.
Liquidity - Our revolving credit facility indebtedness matures on March 7, 2019 and our outstanding senior notes mature on March 15, 2019. As such, all of our outstanding revolving credit and senior note indebtedness is now due within less than one year. Beginning with our consolidated financial statements as of and for the quarter ended March 31, 2018, we have been required to

classify under GAAP all such indebtedness as current liabilities on our consolidated balance sheets. This in turn has caused our current liabilities to exceed our current assets, and has necessitated us receiving two successive short-term waivers of the working capital ratio covenant in our revolving credit facility.
In August 2014, the FASB issued ASU 2014-15, “Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern” (the "Standard"). Under the Standard, management must evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about an entity’s ability to continue as a going concern within one year after the date that the entity’s financial statements are issued. Under the Standard, substantial doubt about an entity’s ability to continue as a going concern exists when relevant conditions and events, considered in the aggregate, indicate that it is probable that the entity will be unable to meet its obligations as they become due within this one year period. This evaluation initially must be undertaken without considering the potential mitigating effect of management’s plans that have not been fully implemented as of the date the financial statements are issued. When substantial doubt exists under this initial determination, management must evaluate whether the mitigating effect of its plans sufficiently alleviates substantial doubt about an entity’s ability to continue as a going concern. The mitigating effect of management’s plans, however, is only considered under the Standard if both (1) it is probable that the plans will be effectively implemented within one year after the date that the financial statements are issued and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within the one year period. Generally, to be considered probable of being effectively implemented, the plans must have been approved before the date that the financial statements are issued. PHI’s accompanying financial statements have been prepared in conformity with GAAP, which contemplates PHI’s continuation as a going concern.
Based on our discussions to date with our advisors and current market conditions, we plan to pursue several alternatives to refinance our short-term indebtedness. Nonetheless, because our plans to refinance our debt have not been finalized, and therefore not within our control, these plans cannot be considered probable. Consequently, in accordance with the Standard, these conditions in the aggregate raise substantial doubt about our ability to continue as a going concern within one year after the date the accompanying financial statements are filed. For additional information about our prior and current refinancing plans, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources.”

6. EARNINGS PER SHARE13. LEASES
The Company adopted ASU 2016-02 standard on a prospective basis on January 1, 2019 and used the effective date as the date of initial application.  Therefore, prior period financial information has not been adjusted and continues to be reflected in accordance with the Company’s historical accounting policy.  The standard establishes a right-of-use (ROU) model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months.

The Company elected to adopt the "package of practical expedients" under ASU No. 2018-11, which allows the Company to carry forward its historical assessments of whether existing agreements contain a lease, classification of existing lease agreements, and treatment of initial direct lease costs. The Company also elected to exclude short-term leases (those with terms of 12 months or less) from the balance sheet presentation and accounts for non-lease and lease components as a single lease component for all asset classes.

The adoption of basicASU 2016-02 had the effects specified in Note 1.

Accounting Policy for Leases
The Company determines if an arrangement is a lease at inception.  All of the Company’s leases are operating leases and diluted earnings per shareare included in ROU assets, accounts payable and operating lease liabilities in the Company's Condensed Consolidated Balance Sheet at March 31, 2019.

ROU assets represent the Company’s right to use an underlying asset for the quarterlease term and six months ended June 30, 2018lease liabilities represent the Company’s obligations to make lease payments arising from the lease.  Operating lease ROU assets and 2017liabilities are as follows:

8. ASSET DISPOSALS
During the first quarter of 2018, we disposed of one light aircraft previously utilized in the Air Medical segment and donated to a charitable organization one aircraft previously used in our Oil and Gas segment. During the second quarter of 2018, we disposed of one medium and one light aircraft previously utilized in the Oil & Gas segment. These aircraft no longer met our strategic needs. Cash proceeds totaled $1.5 million, resulting in a $0.7 million lossrate based on the disposalinformation available at commencement date in determining the present value of these assets.
There were no saleslease payments.  The Company’s lease terms may include options to extend or disposals of aircraft duringterminate the first quarter of 2017. During the second quarter of 2017,lease. The lease term includes options to extend when we disposed of five medium aircraft and related parts inventory utilized in the Oil and Gas segment. These aircraft no longer met our strategic needs.
9. COMMITMENTS AND CONTINGENCIES
Commitments We currently have no aircraft purchase commitments.
Total aircraft deposits of $0.5 million were included in Other Assets as of June 30, 2018. This amount represents a deposit on a future lease buyout option. In the event we do notare reasonably certain to exercise the buyout option, the deposit will be applied against lease payments.
As of June 30, 2018, we had options to purchase aircraft under leases, with such purchase options becoming exercisable in 2018 through 2020. The aggregate option purchase pricesoption. We are $105.9 million in 2018, $129.0 million in 2019, and $22.7 million in 2020. Under current conditions, we believe it is unlikelynot, however, reasonably certain that we will exercise the 2018 purchase options, unless opportunistic conditions arise.
Environmental Matters – We have recorded an estimated liability of $0.15 million as of June 30, 2018 for environmental response costs. Previously, we conducted environmental surveys of our former Lafayette Facility located at the Lafayette Regional Airport, which we vacated in 2001, and determined that limited soil and groundwater contamination exist at two parcels of land at the former facility. An Assessment Report for both parcels was submitted in 2003 (and updated in 2006) to the Louisiana Department of Environmental Quality (LDEQ) and the Louisiana Department of Natural Resources (LDNR). Approvals for the Assessment Report were received from the LDEQ and LDNR in 2010 and 2011, respectively. Since that time, we have performed groundwater samplingany of the required groundwater monitor well installations at both parcelsoptions to extend and submitted these sampling reports to the LDEQ. Pursuant to an agreement with the LDEQ, we provided groundwater sample results semi-annually to the LDEQ for both parcels from 2005 to 2015. LDEQ approved a reductionas such, they have not been included in the sampling program from semi-annual to annual groundwater monitoring in 2015. Based on our working relationship and agreements with the LDEQ, and the results of ongoing former facility parcel monitoring, we believe that ultimate remediation costs for the subject parcels will not be material to our consolidated financial position, operations or cash flows.
Legal Matters – From time to time, we are involved in various legal actions incidental to our business, including actions relating to employee claims, medical malpractice claims, tax issues, grievance hearings before labor regulatory agencies, and miscellaneous third party tort actions. The outcome of these proceedings is not predictable. However, based on current circumstances, we do not believe that the ultimate resolution of our presently pending proceedings, after considering available defenses and any insurance coverage or indemnification rights, will have a material adverse effect on our financial position, results of operations or cash flows.remaining lease terms.

Operating LeasesOverview
We lease certain aircraft, facilities, and equipment used in our operations. The related lease agreements, which include both non-cancelable and month-to-month terms, generally provide for fixed monthly rentals, and certain real estate leases also include renewal options. We generally pay all insurance, taxes, and maintenance expenses associated with these leases. All aircraft leases, contain purchase options exercisable by us at certain dates specifiedand these costs are not included in the lease agreements.liability and are recognized in the period in which they are incurred.
At June 30, 2018, we had approximately $189.8
Total operating lease expense was $10.5 million in aggregate commitments under operating leases of which approximately $22.3 million is payable through the fourth quarter of 2018. The total lease commitments include $163.4and $11.8 million for aircraftthe three months ended March 31, 2019 and $26.4 million for facility2018, respectively.  For the three months ended March 31, 2019, a portion of the total operating lease commitments.
10. GOODWILL
Our Goodwill represents the amount by which our purchase price for the HNZ Offshore Business exceeded the fair value of net assets acquired. Goodwill has an indefinite useful life and is not amortized. We test goodwill for impairment annually as of October 1st or when events or changes in circumstances indicate that a potential impairment exists.
Goodwill of $61.3 million as of June 30, 2018 and December 31, 2017expense relating to short-term leases was as follow:

As of December 31, 2018, future total rentals on our non-cancellable operating leases were $160 million in the carrying valuesaggregate, which consisted of the following: $36 million in 2019; $33 million in 2020; $31 million in 2021; $29 million in 2022; $20 million in 2023; and $11 million thereafter.

We are currently in the process of renegotiating certain of our intangible assets at June 30, 2018, we estimateleases in connection with the Chapter 11 Cases. These negotiations, if successfully completed, will likely impact our amortization expense for the next five years (2018 through 2022) to be $1.6 million per year. For the quarter and six months ended June 30, 2018, amortization expense was $0.4 million and $0.8 million, respectively.obligation under our outstanding leases.

12.14. SEGMENT INFORMATION
PHI is primarily a provider of helicopter transport services, including helicopter maintenance and repair services. We report our financial results through the three reportable segments further described below.

A segment’s operating profit or loss is its operating revenues less its direct expenses and selling, general and administrative expenses. Each segment has a portion of selling, general and administrative expenses that is charged directly to the segment, and a small portion that is allocated. Direct charges represent the vast majority of segment selling, general and administrative expenses. Allocated selling, general and administrative expenses are based primarily on total segment costs as a percentage of total operating costs. A significant portion of our selling, general and administrative expenses are neither charged nor allocated to our segments.
Oil and Gas Segment - Our Oil and Gas segment, headquartered in Lafayette, Louisiana, provides helicopter services primarily for the major integrated and independent oil and gas production companies transporting personnel or equipment to offshore platforms in the Gulf of Mexico and a number of foreign countries. Our customers include Shell Oil Company, BP America

Production Company, ExxonMobil Production Company, and ConocoPhillips Company, with whom we have worked for 35 or more years, and ENI Petroleum, with whom we have worked for more than 20 years. At June 30, 2018,March 31, 2019, we had available for use 125122 aircraft in this segment.

Our fixed-term contracts typically have original terms of one year to seven years (subject to provisions permitting early termination upon relatively short notice by the customers), with payment in U.S. dollars. For the quarters ended June 30,March 31, 2019 and 2018, and 2017, respectively, approximately 57%56% and 51%59% of our total operating revenues were generated by our Oil and Gas segment, with approximately 87% and 88% of these revenues from fixed-term customer contracts. For the six months ended June 30, 2018 and 2017, respectively, approximately 58% and 52% of our total operating revenues were generated by our Oil and Gas segment, with approximately 87%86% and 88% of these revenues from fixed-term customer contracts. The remaining 13%14% and 12% of these revenues were attributable to work in the spot market and ad hoc flights for contracted customers.
Air Medical Segment - The operations of our Air Medical segment are headquartered in Phoenix, Arizona, where we maintain significant separate facilities and administrative staff dedicated to this segment.

We provide Air Medical transportation services for hospitals and emergency service agencies throughout the U.S. As of June 30, 2018,March 31, 2019, our Air Medical segment operated approximately 109110 aircraft in 18 states at 7480 separate locations.

Our Air Medical segment operates primarily under the independent provider model and, to a lesser extent, under the traditional provider model. Under the independent provider model, we have no fixed revenue stream and compete for transport referrals on a daily basis with other independent operators in the area. Under the traditional provider model, we contract directly with the customer to provide their transportation services, with the contracts typically awarded or renewed through competitive bidding. For the quarters ended June 30,March 31, 2019 and 2018, approximately 37% and 2017, approximately 40% and 46% of our total operating revenues were generated by our Air Medical segment, respectively. For the six months ended June 30, 2018 and 2017, approximately 38% and 44%36% of our total operating revenues were generated by our Air Medical segment.

Estimates regarding the payor mix and changes in reimbursement rates are the factors most subject to sensitivity and variability in calculating our allowances. We compute a historical payment analysis of accounts fully closed, by category.
Provisions for contractual discounts and estimated uncompensated care for our Air Medical segment (expressed as a percentage of gross segment billings) were as follows for the periods listed below:
 Quarter Ended  
 June 30,
 Six Months Ended

Provision for contractual discounts 67% 63% 66% 66% 67% 69% 
Provision for uncompensated care 7% 10% 8% 7% 11% 6% 

These percentages are affected by various factors, including rate increases and changes in the number of transports by payor mix.

Net reimbursement per transport from commercial payors generally increases when a rate increase is implemented. Net reimbursement from certain commercial payors, as well as Medicare and Medicaid, generally does not increase proportionately with rate increases.


Net revenue attributable to Insurance, Medicare, Medicaid, and Self-Pay (expressed as a percentage of net Air Medical revenues) were as follows for the periods listed below:

Medicaid 8% 8% 8% 9% 7% 9%
Self-Pay 1% 2% % 2% 2% %

We also have a limited number of contracts with hospitals under which we receive a fixed fee component for aircraft availability and a variable fee component for flight time. Most of our contracts with hospitals contain provisions permitting early termination by the hospital, typically with 180 days’ notice for any reason and generally with penalty. Those contracts generated approximately 16%18% and 18% of the segment’s revenues for the quarters ended June 30,March 31, 2019 and 2018, and 2017, respectively. For the six months ended June 30, 2018 and 2017, these contracts generated approximately 18% of the segment's revenues.
We also derive a small portion of the segment’s revenues from providing services under our patient navigation business.

Technical Services Segment - Our Technical Services segment provides helicopter flight services and helicopter repair and overhaul services for existing flight operations customers that own their aircraft. Costs associated with these services are primarily labor, and customers are generally billed at a percentage above our service costs. WeIn the past, we also have periodically provideprovided flight services to governmental customers under this segment, including our current agreement to operateoperating six aircraft for the National Science Foundation in Antarctica, typically in the first and fourth quarters each year.under a contract that lapsed on April 30, 2019. Also included in this segment are our proprietary Helipass operations, which provide software as a service to certain of our Oil and Gas customers for the purpose of passenger check-in and compliance verification.
For each of the quarters ended June 30,March 31, 2019 and 2018, and 2017, approximately 3% of our total operating revenues were generated by our Technical Services segment. For each of the six month periods ended June 30, 2018 and 2017, approximately 4%7% of our total operating revenues were generated by our Technical Services segment.

15. INVESTMENT IN VARIABLE INTEREST ENTITY
We account for our investment in PHI Century Limited ("PHIC") as a variable interest entity, which is defined as an entity that either (a) has insufficient equity to permit the entity to finance its operations without additional subordinated financial support or (b) has equity investors who lack the characteristics of a controlling financial interest. As of June 30, 2018,March 31, 2019, we had a 49% investment in the common stock of PHIC, a Ghanaian entity. We acquired our 49% interest on May 26, 2011, PHIC’s date of incorporation. The purpose of PHIC is to provide oil and gas flight services in Ghana and the West African region. For the quarter ended June 30, 2018,March 31, 2019, we recorded income in equity of this unconsolidated affiliate of less than $0.1 million compared to loss in equity of $1.0 million for the quarter ended June 30, 2017 relative to our 49% equity ownership. For the six months ended June 30, 2018 and 2017, we recorded a gain in equity of this unconsolidated affiliate of $1.4 million compared to loss in equity of less than $0.1 million and a loss of $2.0 millionfor the quarter ended March 31, 2018 relative to our 49% equity ownership, respectively.ownership. We had $5.5$4.1 million and $4.0$4.8 million of trade receivables from PHIC as of June 30, 2018March 31, 2019 and December 31, 2017, respectively, from PHIC. During the six months ended June 30,2018, respectively. In 2018 we loaned PHIC $0.3$0.4 million for operating purposes. The $0.3 millionThis loan balance is included in Accounts receivable - other on our Condensed Consolidated Balance Sheets at June 30, 2018.March 31, 2019. Our investment in the common stock of PHIC is included in Other Assets on our Condensed Consolidated Balance Sheets and was $0.4$1.9 million at June 30, 2018March 31, 2019 and $0.3$0.5 million at December 31, 2017.2018.

14.16. OTHER COMPREHENSIVE INCOME
Amounts reclassified from Accumulated other comprehensive income are not material and, therefore, not presented separately in the Condensed Consolidated Statements of Comprehensive Income.

15.17. CONDENSED CONSOLIDATING FINANCIAL INFORMATION
As discussed further in Note 5,6, on March 17, 2014, PHI, Inc. issued $500.0 million aggregate principal amount of 5.25% Senior Notes due 2019 that are fully and unconditionally guaranteed on a joint and several, senior basis by all of PHI, Inc.’s domestic subsidiaries. PHI, Inc. directly or indirectly owns 100% of all of its domestic subsidiaries.

The supplemental condensed financial information on the following pages sets forth, on a consolidated basis, the balance sheet, statement of operations, statement of comprehensive income, and statement of cash flows information for PHI, Inc. (“Parent Company”) the guarantor subsidiaries and the non-guarantor subsidiaries, each under separate headings. The eliminating entries eliminate investments in subsidiaries, intercompany balances, and intercompany revenues and expenses. The condensed consolidating financial statements have been prepared on the same basis as the consolidated financial statements of PHI, Inc. The equity method is followed by the Parent Company within the financial information presented below.

The transactions reflected in “Due to/from affiliates, net” in the following condensed consolidated statements of cash flows primarily consist of centralized cash management activities between PHI, Inc. and its subsidiaries, pursuant to which cash earned by the guarantor subsidiaries is regularly transferred to PHI, Inc. to be centrally managed. Because these balances are treated as short-term borrowings of the Parent Company, serve as a financing and cash management tool to meet our short-term operating needs, turn over quickly and are payable to the guarantor subsidiaries on demand, we present borrowings and repayments with our affiliates on a net basis within the condensed consolidating statement of cash flows. Net receivables from our affiliates are considered advances and net payables to our affiliates are considered borrowings, and both changes are presented as financing activities in the following condensed consolidating statements of cash flows.

Item 2.     MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This discussion and analysis should be read in conjunction with (i) the accompanying unaudited condensed consolidated financial statements and the notes thereto (the “Notes”) and (ii) our Annual Report on Form 10-K for the year ended December 31, 2017,2018, including the audited consolidated financial statements and notes thereto, management’s discussion and analysis, and the risk factor disclosures contained therein.
Overview

As described further in Note 12,14, we are primarily a provider of helicopter transport services and derive most of our revenue from providing these services to the energy and medical industries. Our consolidated results of operations are principally driven by the following factors:

We expect the pending Chapter 11 Cases will impact our business. Certain of our customers have advised us that they will not enter into additional contracts with us during the Chapter 11 Cases. We also are expending substantial amounts of cash on professional fees relating to the reorganization process. For information on additional impacts of the Chapter 11 Cases, see (i) the balance of this Item 2, (ii) Note 2 and (iii) Item 1 of Part II of this report.

The level of offshore oil and gas exploration and production activities in the areas in which we operate. Operating revenues from our Oil and Gas segment relate substantially to operations in the Gulf of Mexico and a couple of our other key offshore markets. Many of the helicopters we have purchased recently are larger aircraft intended to service deepwater activities and the margins we earn on these aircraft are generally higher than on smaller aircraft. During periods when the level of offshore activity increases, demand for our offshore flight services typically increases, directly affecting our revenue and profitability. Also, during periods when deepwater offshore activity increases, the demand for our medium and heavy aircraft usually increases, creating a positive impact on revenue and earnings. Conversely, a reduction in offshore oil and gas activities generally, or deepwater offshore activity particularly, typically negatively impacts our aircraft utilization, flight volumes, and overall demand for our aircraft, thereby creating a negative impact on our revenue and earnings.

Our recent acquisition of the HNZ Offshore Business has increased the scope of our Oil and Gas segment. On December 29, 2017, we acquired the offshore helicopter services business formerly conducted in New Zealand, Australia, the Philippines and Papua New Guinea (the “HNZ Offshore Business”) by HNZ Group, Inc. (“HNZ”). Our consolidated financial statements include the accounts of the HNZ Offshore Business beginning on January 1, 2018. Accordingly, you should consider the impact of our acquisition of the HNZ Offshore Business when comparing our results of operations for periods ending June 30, 2018 to our results for any prior periods.

Patient transports and flight volume in our Air Medical segment. In the independent provider programs under our Air Medical segment, our revenue is directly dependent upon the number and length of patient transports provided in a given period, which is impacted primarily by the number of bases operated by us, competitive factors and weather. The volume of flight utilization of our aircraft by our customers under our traditional provider Air Medical programs also has a direct impact on the amount of revenue earned in a given period, although to a lesser degree than under our independent provider programs. Independent provider programs generated approximately 83%80%, 81%80%, 81% and 74% of our Air Medical segment revenues for the sixthree months ended June 30, 2018,March 31, 2019, and the years ended December 31, 2018, 2017 2016 and 2015,2016, respectively, with the balance of our Air Medical segment revenue attributable to our traditional provider programs.

Payor mix and reimbursement rates in our Air Medical segment. Under our independent provider programs, our revenue recognition, net of allowances, during any particular period is dependent upon the rate at which our various types of customers reimburse us for our Air Medical services, which we refer to as our “payor mix.” Reimbursement rates vary among payor types and typically the reimbursement rate of commercial insurers is higher than Medicare, Medicaid, and self-pay reimbursement rates. Moreover, Medicare and Medicaid reimbursement rates have decreased in recent years and our receipt of payments from these programs is subject to various regulatory and appropriations risks discussed in our periodic reports filed with the SEC. Changes during any particular period in our payor mix, reimbursement rates, or uncompensated care rates will have a direct impact on our revenues.

Direct expenses. Our business is capital-intensive and highly competitive. Salaries and aircraft maintenance comprise a large portion of our operating expenses. Our aircraft must be maintained to a high standard of quality and undergo periodic and routine maintenance procedures. Higher utilization of our aircraft will result in more frequent maintenance, resulting in higher maintenance costs. In periods of low flight activity, we continue to maintain our aircraft, consequently reducing our margins. In addition, we are also dependent upon pilots, mechanics, and medical crew to operate our business. To attract and retain qualified personnel, we must maintain competitive wages, which places downward pressure on our margins.

As noted above, the performance of our oil and gas operations is largely dependent upon the level of offshore oil and gas activities,

which in turn is based largely on volatile commodity prices. See “Risk Factors” in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2017.2018. Since mid-2014, prevailing oil prices have been substantially lower than prices for several

years before then. Consequently, several of our oil and gas customers curtailed their exploration or production levels, lowered their capital expenditures, reduced their staffs or requested arrangements with vendors designed to reduce their operating costs, including flight sharing arrangements and alternative platform staffing rotations. As explained further below, theseThese changes havecreated overcapacity in the offshore flight services industry and negatively impacted our oil and gas operations since the first quarter of 2015. Over the course of the downturn, several of our offshore customers have requested reductions in the volume or pricing of our flight services or have re-bid existing contracts, all of which has further reduced our aircraft utilization rates and intensified pricing pressures. Although various experts believe the negative consequences of the market downturn have crested, we cannot assure you of this. For information on the adverse impact of thethis market downturn on our liquidity, see “- Liquidity and Capital Resources - Cash Flow - Liquidity”Resources" below.

Voluntary Reorganization under Chapter 11
On March 14, 2019, the Debtors filed voluntary petitions in the Bankruptcy Court seeking relief under the Bankruptcy Code. The Chapter 11 Cases are being jointly administered under the caption "In re PHI, Inc., et al., Case No. 19-30923." Documents filed on the docket of and other information related to the Chapter 11 Cases are available free of charge online at https://restructuring.primeclerk.com/PHI. Documents and other information available on such website are not part of this document and shall not be deemed incorporated by reference in this document. The Debtors are authorized to continue to operate their businesses and manage their properties as "debtors in possession" under the jurisdiction of the Bankruptcy Code and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court. Certain subsidiaries of PHI (collectively, the "Non-Filing Entities") were not part of the Chapter 11 Cases. The Non-Filing Entities will continue to operate their businesses in the normal course and their results are included in our interim Unaudited Condensed Consolidated Financial Statements.

Subject to certain exceptions, under the Bankruptcy Code, the filing of the Chapter 11 Cases automatically enjoined, or stayed, the continuation of most judicial or administrative proceedings or filing of other actions against the Debtors or their property to recover, collect or secure a claim arising prior to the Commencement Date. Accordingly, except with respect to certain payments required to be made as adequate protection under the Bankruptcy Code and applicable Bankruptcy Court orders, any efforts to enforce payment obligations under the Company's pre-petition debt instruments are automatically stayed as a result of the filing of the Chapter 11 Cases and are subject to the applicable provisions of the Bankruptcy Code.

For the duration of the Chapter 11 Cases, the Company's operations and ability to develop and execute its business plan are subject to the risks and uncertainties associated with the Chapter 11 process. As a result of these risks and uncertainties, the amount and composition of the Company's assets, liabilities, officers and directors could be significantly different following the outcome of the Chapter 11 Cases. The description of the Company's operations, properties, liquidity, capital resources, capital structure, ownership or governance included in this or other of our periodic reports or in the Plan may not accurately reflect its operations, properties, liquidity, capital resources, capital structure, ownership or governance following resolution of the Chapter 11 Cases.

The accompanying interim Unaudited Condensed Consolidated Financial Statements have been prepared assuming that PHI will continue as a going concern and contemplates continuity of operations, realization of assets and satisfaction of liabilities and commitments in the normal course of business. Our ability to continue as a going concern is contingent upon our ability to comply with the financial and other covenants contained in the Blue Torch Finance, LLC term loan described in Note 6 of the Notes to Condensed Consolidated Financial Statements and discussed further below under "Liquidity", and our ability to successfully implement, subject to the Bankruptcy Court's approval, a restructuring plan, among other factors. We have significant indebtedness. Our level of indebtedness has adversely impacted and continues to adversely impact our financial condition. As a result, our financial condition and the risks and uncertainties surrounding our Chapter 11 proceedings raise substantial doubt as to our ability to continue as a going concern.

Furthermore, the realization of assets and the satisfaction of liabilities are subject to uncertainty. While operating as debtors-in-possession under Chapter 11, the Debtors may sell or otherwise dispose of or liquidate assets or settle liabilities, subject to the approval of the Bankruptcy Court or as otherwise permitted in the ordinary course of business and subject to restrictions of our term loan financing (see Note 6 of Notes to Condensed Consolidated Financial Statements) and applicable orders of the Bankruptcy Court, for amounts other than those reflected in the accompanying Unaudited Condensed Consolidated Financial Statements. Any such actions occurring during the Chapter 11 Cases confirmed by the Bankruptcy Court could materially impact the amounts and classifications of assets and liabilities reported in PHIs' interim Unaudited Condensed Consolidated Financial Statements.

Under the absolute priority scheme established by the Bankruptcy Code, unless our creditors agree otherwise, all of our pre-petition liabilities and post-petition liabilities must be satisfied in full before the holders of our existing common stock may receive any distribution or retain any property under a plan of reorganization. The ultimate recovery to creditors and/or shareholders, if any, will not be determined until confirmation and implementation of a plan or plans of reorganization. We can give no assurance that any recovery or distribution of any amount will be made to any of our creditors or shareholders. Our plan of reorganization could result in any of our stakeholders, including our equity holders, receiving no distribution on account of their interests and cancellation

of their holdings. Moreover, a plan of reorganization can be confirmed, under the Bankruptcy Code, even if the holders of our common stock vote against the plan of reorganization and even if the plan of reorganization provides that the holders of our common stock receive no distribution on account of their equity interests.

Oil and Gas -Oil and Gas segment revenues were $192.7 million for the six months ended June 30, 2018, compared to $146.4 million for the six months ended June 30, 2017. Of this $46.3 million increase, $23.2 million was attributable to an increase in revenues derived from our newly-acquired HNZ Offshore Business, and the remainder was attributable to an increase in revenues from our legacy international aircraft, partially offset by a decrease in revenues from our legacy Gulf of Mexico offshore aircraft. Our Oil and Gas segment revenues are primarily driven by the amount of contracted aircraft flight hours and prevailing rates. Costs are primarily fixed based on the number of aircraft operated, with a variable portion that is driven by flight hours.

Oil and Gas segment flight hours were 42,978 for the current six months compared to 37,157 for the same six months in the prior year. Of this increase of 5,821 flight hours, 5,713 hours were attributable to our newly-acquired HNZ operations and the reminder to higher utilization rates of our light and heavy legacy aircraft.

The number of aircraft available for use in the segment was 125 at June 30, 2018, compared to 128 at June 30, 2017. We terminated leases on two heavy aircraft and disposed of one light and two medium aircraft in the Oil and Gas segment since June 30, 2017. We added 9 medium aircraft in the Oil and Gas segment since June 30, 2017, as a result of our acquisition of the HNZ Offshore Business. Transfers between segments account for the remainder.

Direct expense in our Oil and Gas segment was $191 million for the six months ended June 30, 2018, compared to $155.4 million for the six months ended June 30, 2017, an increase of $35.6 million. We experienced an increase in aircraft warranty costs of $19.5 million partly as a result of a prior period $8.9 million non-recurring credit due to the cancellation of a warranty program on some of our medium aircraft fleet. The remainder of the $19.5 million increase was due to increased flight hours for our heavy aircraft in our international operations, and the addition of a new warranty program for our medium aircraft at the beginning of 2018. Salaries and wages increased by $12.1 million due to our recent HNZ acquisition. Fuel expense increased $4.2 million and other items decreased $0.2 million, net.

Selling, general and administrative segment expenses were $9.3 million for the six months ended June 30, 2018 and $3.4 million for the six months ended June 30, 2017. The $5.9 million increase is mainly attributable to an increase in salaries and wages and other administrative costs due to our newly-acquired HNZ international operations.

Oil and Gas segment loss was $7.6 million for the six months ended June 30, 2018, compared to a loss of $12.4 million for the six months ended June 30, 2017. The $4.8 million decrease in segment loss is attributable to a $46.3 million increase in segment revenues, partially offset by $41.5 million increase in aggregate segment expenses.

Air Medical -Air Medical segment revenues were $124.1 million for the six months ended June 30, 2018, compared to $122.6 million for the six months ended June 30, 2017. This increase of $1.5 million is attributable to a $1.2 million increase in independent provider program revenue and a $0.3 million increase in traditional provider program revenue. Patient transports were 9,324 for the six months ended June 30, 2018, compared to 9,418 for the same period in the prior year.

The number of aircraft available for use in the segment was 109 at June 30, 2018 compared to 104 at June 30, 2017. Since June 30, 2017, our Air Medical segment disposed of two light aircraft. Transfers between segments account for the remainder.

Direct expense in our Air Medical segment was $110.6 million for the six months ended June 30, 2018, compared to $101.2 million for the six months ended June 30, 2017, an increase of $9.4 million. Employee compensation costs increased $6.1 million due to increased labor costs period over period. Fuel cost increased $0.6 million, and repair cost increased $1.3 million, primarily due to increased flight volume. Other items increased $1.4 million, net.

Selling, general and administrative segment expenses were $6.4 million for the six months ended June 30, 2018 and $6.1 million for the six months ended June 30, 2017. The increase is associated with increased contracted labor costs and other administrative costs.

Air Medical segment profit was $7.1 million for the six months ended June 30, 2018, compared to a segment profit of $15.2 million for the six months ended June 30, 2017. The $8.1 million decrease in profit is primarily attributable to the increased expenses described above.

Technical Services - Technical Services segment revenues were $12.8 million for the six months ended June 30, 2018, compared to $12.1 million for the six months ended June 30, 2017. The $0.7 million increase in revenue is due primarily to an increase in revenue from our (i) Antarctica and Helipass operations, (ii) parts sales and (iii) new government contract that began in 2018. These increases were partially offset by a decrease in revenue derived from a third party customer whose service requirements typically vary from period to period. Direct expenses increased $0.9 million compared to the prior year six month period, principally due to the increase in our Antarctica operations and the new government contract, partially offset by a decrease in expenses related to the third party customer mentioned above. Technical Services segment profit was $2.4 million for the six months ended June 30, 2018, compared to segment profit of $2.6 million for the six months ended June 30, 2017.

Liquidity and Capital Resources

General

Our ongoing liquidity requirements arise primarily from the purchase or leasing of aircraft, the maintenance and refurbishment of aircraft, the opening of new aircraft bases, the expansion or improvement of facilities, the acquisition of equipment and inventory, and other working capital needs.needs, as well as the costs associated with our Chapter 11 Cases during their pendency. Our principal sources of liquidity historically have been net cash provided by our operations, borrowings under oura revolving credit facility, and proceeds from periodic senior note offerings. To the extent we do not use cash, short-term investments or borrowings to financeWe have also periodically funded certain of our aircraft acquisitions we frequently enter intothrough sale-leaseback transactions to fund these acquisitions.

Liquidity

Recently, our liquidity and ability to comply with our debt covenants have been negatively impacted by several factors, including:
the prolonged slowdown in exploration and production activity by the customers in our Oil and Gas segment;
our leverage; and
our use of over $130 million of our short-term investments to fund our acquisition of the HNZ Offshore Business in late 2017.

As discussed further below under “Short-Term Debt,” beginning in the third quarter of 2016, we have on several occasions sought and received concessions from our revolving credit facility lenders to enable us to remain in compliance with various financial covenants. The most recent of these concessions was granted with respect to the second quarter of 2018, when these lenders granted us a waiver for the period ending June 30, 2018 from the requirement to maintain a 2 to 1 ratio of current assets to current liabilities.


Our revolving credit facility indebtedness matures on March 7, 2019 and our outstanding senior notes mature on March 15, 2019. As such, all of our outstanding revolving credit and senior note indebtedness is now due within less than one year. Beginning with our consolidated financial statements as of and for the quarter ended March 31, 2018, we have been required to classify under GAAP all such indebtedness as current liabilities on our consolidated balance sheets. As of June 30, 2018, we had (i) total current liabilities of $712.3 million, of which $620.5 million was indebtedness classified as long-term debt at December 31, 2017, and (ii) total current assets of $352.0 million.

In late 2017, we retained advisors to begin assisting us in evaluating alternatives to refinance our outstanding indebtedness. In February 2018, following the completion of our acquisition of the HNZ Offshore Business in December 2017, we continued our exploration of refinancing alternatives, including a broad assessment of interest rates and other prevailing conditions in the capital markets. During the first quarter of 2018, we explored several alternatives but deferred taking action until management could more fully evaluate additional potential refinancing opportunities. In June 2018, we sought to refinance all of our outstanding short-term indebtedness with the net proceeds from a senior secured note offering and two new secured credit facilities. Although several lenders expressed a willingness to loan us money under the newly-proposed credit facilities, we have thus far been unable to raise funds that, in our judgement, are sufficient in amount and contain terms that are fiscally prudent. As of the date of the filing of this report, we are continuing to explore a variety of options for refinancing our short-term indebtedness.

Based on our discussions to date with our advisors and current market conditions, we believe there are several alternatives that we can pursue to refinance our short-term indebtedness. Nonetheless, because our plans to refinance our debt have not been finalized, and therefore are not within our control, these plans cannot be considered probable. As such, these plans cannot be considered to be probable of occurring within the meaning of ASU 2014-15 discussed in Note 5 (the "Standard"). Consequently, in accordance with the Standard, these conditions in the aggregate continue to raise substantial doubt about our ability to continue as a going concern within one year after the date the financial statements included herein are filed.

For additional information about ASU 2014-15, see Note 5. For additional information about the uncertainties and risks of our refinancing plans, see Item 1A of Part II of this report.transactions.

Senior Notes -In 2014, we owed $622.2 million under our total long-term debt, consisting ofissued $500.0 million principal amount of 5.25% Senior Secured Notes dueNotes. These notes matured on March 15, 2019 (excluding debt issuance costs) and $122.2 million borrowed under our revolving credit facility.2019. For more information, see Note 6.


Revolving Credit FacilityRelated Party Term Loan -Our amendedWe owe $130 million under a term loan provided by the financing affiliate of our CEO and restatedcontrolling shareholder. On September 28, 2018, we applied the proceeds from this term loan principally to repay approximately $122.7 million of principal and accrued interest under our senior secured revolving credit facility (our “revolving credit facility”) matures on March 7, 2019. Under our revolving credit facility, we can borrow up to $130.0 million at floating interest rates based on the London Interbank Offered Rate (as defined in our revolving credit facility), plus 275 basis points. Our revolving credit facility includes usual and customary covenants and events of default for credit facilities of its type. Our ability to borrowfacility. Obligations under the revolving credit facility is conditioned uponterm loan are guaranteed by two of our continued compliance with such covenants, including, among others, (i) covenants that restrict our ability to engage in certain asset sales, mergers or other fundamental changes, to incur liens or to engage in certain other transactions or activitiesprincipal subsidiaries, and (ii) financial covenants that stipulate that PHI will maintain a consolidated working capital ratio of at least 2 to 1, a net funded debt to consolidated net worth ratio not greater than 1.5 to 1, a fixed charge coverage ratio of at least 1 to 1 if our short-term investments fall below $150.0 million, and consolidated net worth of at least $500.0 million (with all such terms or amounts as defined in or determinedthe Company’s obligation under the revolving credit facility). Borrowingsterm loan and the guarantors’ obligations under our revolving credit facilitytheir guaranty agreement are secured on a first-priority basis by our inventory spare parts and accounts receivable.

During the fourth quarter of 2017, we amended our revolving credit facility to (i) extend the maturity date of the line of credit from October 1, 2018 to March 7, 2019, (ii) decrease the revolving line of credit from $150.0 million to $130.0 million, (iii) limit extensions of credit under the revolving line of credit to a borrowing base calculated periodically based on specified percentages of the value of eligible accounts and eligible inventory and the value of certain short-term investments, and (iv) effect the fixed-charge coverage ratio waiver notedreceivable located in the next paragraph. The amendment also amendedUnited States, as well as certain specified interest rates and various covenants, including amendments that changed the fixed charge coverage ratio from 1.10 to 1.00 to 1.00 to 1.00, calculated on a quarterly basis, changed the Company’s required consolidated net worth from $450.0 million to $500.0 million, and permitted debt in an aggregate principal amount not to exceed $5.0 million to accommodate an international working capital line of credit.

During the third quarter of 2016, our revolving credit facility lenders agreed to amend our financial covenants to alleviate concerns about our future ability to remain in compliance with a requirement to maintain a fixed charge coverage ratio of 1 to 1. Specifically, the lenders agreed to test compliance with this ratio requirement only if at the end of any quarter our short-term investments were below $150 million. In the fourth quarter of 2017, these lenders waived our obligation to comply with our amended fixed charge coverage requirement for the fiscal quarters ending on December 31, 2017 and March 31, 2018. As of June 30, 2018, our short-term investments were $60.3 million. Although our short-term investments were less than $150.0 million as of June 30, 2018, we were in compliance with this fixed charge coverage ratio covenant for the second quarter of 2018.

As noted above under “—Liquidity,” our revolving credit facility lenders waived our obligation to comply with our working capital ratio covenant as of March 31, 2018 and June 30, 2018. Although we hope to refinance our revolving credit facility before it matures, we cannot assure you of this.

Accordingly, we cannot assure you that we will be able to comply in future quarters with all of the financial covenants in our revolving credit facility or any other of our then-existing debt agreements.spare parts.

Operating Lease Commitments - At March 31, 2019, we leased 16 of our 240 aircraft (or 7%) under 16 separate aircraft lease agreements with 13 lessors. As of June 30, 2018,March 31, 2019, we had options to purchase aircraft under these leases becoming exercisable in 2018 through2019 and 2020. The aggregate option purchase prices are $105.9 million in 2018, $129.0$109.5 million in 2019 and $22.7 million in 2020. Under current conditions, we believe it is unlikely that we will exercise the 2018these purchase options arising over the next year, unless opportunistic conditions arise. As noted above, we are currently renegotiating several of our aircraft leases in connection with the Chapter 11 Cases.

Item 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk is the risk of changes in the value of financial instruments, or in future net income or cash flows, in response to changing market conditions. 

OurPrior to the retirement of our revolving credit facility on September 28, 2018, our earnings arewere subject to changes in short-term interest rates due to the variable interest rate payable under our credit facility debt.facility.

Our new term loan with Blue Torch, LLC. is subject to changes in short-term interest rates due the variable component of LIBOR. Based on the $118.2 millionprincipal amount weighted average loan balance of our variable-rate debt during the sixthree months ended June 30, 2018,March 31, 2019, a 10% increase (0.4436%(0.2610%) in interest rates would have reduced our annual pre-tax earnings approximately $0.5$0.2 million, but would not have changed the fair market value of this debt.

Our $500.0 million principal amount of outstanding 5.25% Senior Notes duethat matured on March 15, 2019 bearaccrued interest at a fixed rate of 5.25% and therefore changes in market interest rates do not affect our interest payment obligations on the notes. The fair market value of our 5.25% Senior Notes will vary as changes occur to general market interest rates, the remaining maturity of the notes, and our creditworthiness. At June 30, 2018,March 31, 2019, the market value of the notes was approximately $490.6$313.2 million, based on quoted market prices. See Note 4.

The interest and other payments we earn and recognize on our investments in money market funds U.S. Government agencies debt, commercial paper, and corporate bonds and notes are subject to the risk of declines in general market interest rates.

See Note 4 for additional information.
Item 4.    CONTROLS AND PROCEDURES


The Company’s management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934) as of the end of the period covered by this report. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that the design and operation of our disclosure controls and procedures were effective as of such date to ensure that information required to be disclosed by us in the reports that we file or furnish under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission, including to ensure that such information is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

There have been no changes in our internal control over financial reporting that occurred during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

As previously disclosed, we still intend to extend our above-described internal control oversight and monitoring processes to cover our newly-acquired HNZ operations by the end of 2018.

The effectiveness of our or any system of disclosure controls and procedures is subject to certain limitations, including the exercise of judgment in designing, implementing and evaluating the controls and procedures, the assumptions used in identifying the

likelihood of future events and the inability to eliminate misconduct completely. As a result, we cannot assure you that our disclosure controls and procedures will detect all errors or fraud.

Item 1.    LEGAL PROCEEDINGS

For information regarding legal proceedings, see “Legal Matters” in Note 9 to our financial statements included in this report, incorporated herein by reference.
 
Item 1A. RISK FACTORS

For information regarding certain risks relating to our operations, any of which could negatively affect our business, financial condition, operating results or prospects, see (i) Item 1A. “Risk Factors”1A - "Risk Factors" of our Annual Report on Form 10-K for the year ended December 31, 20172018 and (ii) the supplemental disclosure below:below.

We may not be able to obtain confirmation of a Chapter 11 plan of reorganization.
On April 1, 2019, the Debtors filed with the Bankruptcy Court the Debtors’ Joint Chapter 11 Plan of Reorganization (the “Plan”) and the Disclosure Statement related thereto, and soon expect to file with the Bankruptcy Court an amended Joint Chapter 11 Plan of Reorganization and related Disclosure Statement. To emerge successfully from Bankruptcy Court protection as a viable entity, we must meet certain statutory requirements with respect to adequacy of disclosure with respect to a Chapter 11 plan of reorganization, solicit and obtain the requisite acceptances of such a reorganization plan and fulfill other statutory conditions for confirmation of such a plan. However, even if our Plan meets other requirements under the Bankruptcy Code, creditors may not vote in favor of our Plan, and certain parties in interest may file objections to the Plan in an effort to persuade the Bankruptcy Court that we have not satisfied the confirmation requirements under section 1129 of the Bankruptcy Code. Even if no objections are filed and the requisite acceptances of our Plan are received from creditors entitled to vote on the Plan, the Bankruptcy Court, which can exercise substantial discretion, may not confirm the Plan. The consolidated financial statements included herein contain disclosuresprecise requirements and evidentiary showing for confirming a plan, notwithstanding its rejection by one or more impaired classes of claims or equity interests, depends upon a number of factors including, without limitation, the status and seniority of the claims or equity interests in the rejecting class.

If the Plan is not confirmed by the Bankruptcy Court, it is unclear whether we would be able to reorganize our business and what, if anything, holders of claims against us would ultimately receive with respect to their claims.

Even if a Chapter 11 plan of reorganization is consummated, we may not be able to achieve our stated goals and continue as a going concern.
Even if the Plan or another Chapter 11 plan of reorganization is consummated, we will continue to face a number of risks, including further deterioration in commodity prices, overcapacity of helicopters, adverse weather conditions, changes in demand for our services, increased expenses, increased competition, or other changes in our markets or industry. Accordingly, we cannot guarantee that express substantial doubt aboutthe Plan or any other Chapter 11 plan of reorganization will achieve our stated goals.
Furthermore, even if our debts are reduced or discharged through the Plan, we may need to raise additional funds through public or private debt or equity financing or other various means to fund our business after the completion of our Chapter 11 proceedings. Our access to additional financing is, and for the foreseeable future will likely continue to be, limited, if it is available at all. Therefore, adequate funds may not be available when needed or may not be available on favorable terms, if they are available at all.
We cannot assure you of our ability to continue as a going concern, indicatingconcern.
For all the possibility that we may not be able to operatereasons described in the future.

The consolidated financial statements included herein have been prepared on a going concern basis, which assumes that we will continue to operate in the future in the normal course of business. Recently,this report and our liquidity andprior periodic reports, including uncertainty about our ability to maintain compliance with debt covenants have been negatively impacted by several factors, including the prolonged slowdown in exploration and production activity by the customers in our Oil and Gas segment, by our leverage and by our useconfirm a plan of cash equivalents to fund our acquisition of the HNZ Offshore Business in late 2017. As of June 30, 2018, all of our revolving credit indebtedness (which matures on March 7, 2019) and all of our senior note indebtedness (which matures on March 15, 2019) was due within less than one year, which under GAAP necessitated classifying all such indebtedness as current liabilities on our accompanying balance sheet as of such date. Consequently, as of June 30, 2018, we had (i) total current liabilities of $712.3 million, of which $352.0 million was indebtedness classified as long-term debt at December 31, 2017, and (ii) total current assets of $346.3 million. As discussed elsewhere herein, we have also been required on several occasions since 2016 to receive concessions from our revolving credit facility lenders to enable us to remain in compliance with various financial covenants.

As noted elsewhere herein, we believe there are several alternatives we can pursue to refinance our outstanding short-term indebtedness before it becomes due. For a variety of reasons, however, we cannot provide you with any assurances that these efforts will be successful in the near termreorganization or at all. Failure to satisfy any of the financial covenants in our revolving credit facility could cause us to suffer an event of default, which could under certain circumstances, among other things, accelerate our obligations under such facility or preclude us from makingobtain future borrowings thereunder. Moreover, in some cases a breach of these covenants or any other default under our revolving credit facility may create an event of default under our outstanding senior notes, resulting in the acceleration of our obligation to pay principal, interest and potential penalties under such notes (even though we may otherwise be in compliance with our obligations under those notes and the associated indenture). Our revolving credit facility includes a similar cross-default provision. Thus, an event of default under either our revolving credit facility or senior notes, including one that is technical in nature or otherwise not material, could result in the acceleration of significant indebtedness under the other. If we were to default under our debt obligations,financing, we cannot assure you that we would be able to borrow or otherwise obtain enough cash to repay the accelerated indebtedness. In accordance with applicable accounting standards, these conditions in the aggregate raise substantial doubt aboutof our ability to continue as a going concern within one year after the date the financial statements included herein are filed.concern.

For additional information on the above-referenced accounting standards and our plans to refinance our debt, see Note 5 of the financial statements included under Item 1 of Part I of this report and the discussion included in Item 2 of Part I of this report, respectively.
