The following table presents the cost and fair value of our debt investments based on maturities as of: March 31, 2017 December 31, 2016 Amortized Fair Amortized Fair Costs Value Costs Value (Thousands of dollars) Due in one year or less $ 200,195 $ 199,906 $ 184,587 $ 184,334 Due within two years 79,570 79,338 100,816 100,378 Total $ 279,765 $ 279,244 $ 285,403 $ 284,712 The following table presents the average coupon rate percentage and the average days to maturity of our debt investments as of: March 31, 2017 December 31, 2016 Average Average Average Average Coupon Days To Coupon Days To Rate (%) Maturity Rate (%) Maturity Commercial paper 1.035 140 1.001 184 U.S. Government agencies 1.056 355 0.970 400 Corporate bonds and notes 1.731 287 1.745 318 The following table presents the fair value and unrealized losses related to our investments that have been in a continuous unrealized loss position for less than twelve months as of: March 31, 2017 December 31, 2016 Unrealized Unrealized Fair Value Losses Fair Value Losses (Thousands of dollars) Commercial paper $ 27,909 $ (26 ) $ 27,867 $ (39 ) U.S. Government agencies 14,285 (20 ) 13,263 (32 ) Corporate bonds and notes 207,512 (460 ) 210,836 (602 ) Total $ 249,706 $ (506 ) $ 251,966 $ (673 ) The following table presents the fair value and unrealized losses related to our investments that have been in a continuous unrealized loss position for more than twelve months as of: March 31, 2017 December 31, 2016 Unrealized Unrealized Fair Value Losses Fair Value Losses (Thousands of dollars) Corporate bonds and notes $ 20,116 $ (19 ) $ 24,196 $ (20 ) Total $ 20,116 $ (19 ) $ 24,196 $ (20 ) 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 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 March 31, 2017 or December 31, 2016. We have also determined that we did not have any other than temporary impairments relating to credit losses on debt securities for the quarter ended March 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

Revenue Recognition and Valuation Accounts	3. REVENUE RECOGNITION AND 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, 2017, and $6.0 million at December 31, 2016. 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 $107.6 million and $111.9 million as of March 31, 2017 and December 31, 2016, respectively. The allowance for uncompensated care was $48.0 million and $46.3 million as of March 31, 2017 and December 31, 2016, 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 $2.5 million for the quarters ended March 31, 2017 and 2016. The estimated cost of providing charity services was $0.6 million for the quarters ended March 31, 2017 and 2016. 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) was as follows: As of March 31, December 31, Allowance for Contractual Discounts 56 % 56 % Allowance for Uncompensated Care 25 % 23 % Under a three-year contract that commenced on September 29, 2012, our Air Medical affiliate provided multiple services to a customer in the Middle East, including helicopter leasing, emergency medical helicopter flight services, aircraft maintenance, provision of spare parts, insurance coverage for the customer-owned aircraft, training services, and base construction. Each of the major services mentioned above qualified as separate units of accounting under the accounting guidance for such arrangements. The selling price for each specific service was determined based upon third-party evidence and estimates. As discussed in greater detail in our Form 10-K We have also established valuation reserves related to obsolete and slow-moving spare parts inventory. The inventory valuation reserves were $17.7 million and $17.3 million at March 31, 2017 and December 31, 2016, respectively.

Fair Value Disclosures [Abstract]
Fair Value Measurements	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: March 31, 2017 Total (Level 1) (Level 2) (Thousands of dollars) Investments: Money market mutual funds $ 10,597 $ 10,597 $ — Commercial paper 27,909 — 27,909 U.S. Government agencies 15,285 — 15,285 Corporate bonds and notes 236,050 — 236,050 289,841 10,597 279,244 Deferred compensation plan assets 2,500 2,500 — Total $ 292,341 $ 13,097 $ 279,244 December 31, 2016 Total (Level 1) (Level 2) (Thousands of dollars) Investments: Money market mutual funds $ 18,118 $ 18,118 $ — Commercial paper 27,867 — 27,867 U.S. government agencies 13,263 — 13,263 Corporate bonds and notes 243,582 — 243,582 302,830 18,118 284,712 Deferred compensation plan assets 2,394 2,394 — Total $ 305,224 $ 20,512 $ 284,712 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 shares of 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 March 31, 2017 and December 31, 2016. Our determination of the estimated fair value of our Senior Notes and our revolving credit facility debt is derived using Level 2 inputs, including quoted market indications of similar publicly-traded debt. The fair value of our Senior Notes, based on quoted market prices, was $473.8 million and $474.4 million at March 31, 2017 and December 31, 2016, respectively.

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, 2016 at specified redemption prices. 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 – Cash paid to fund interest expense was $14.1 million for the quarter ended March 31, 2017 and $13.7 million for the quarter ended March 31, 2016. Letter of Credit Facility - We also have outstanding a letter of credit for $7.6 million issued under our $150.0 million credit facility that reduces the amount we can borrow under that facility. The letter of credit was issued to guaranty our performance under an international contract that was awarded in late 2016. Other

The aggregate option purchase prices are $37.1 million in 2017, $127.0 million in 2018, $129.0 million in 2019, and $22.7 million in 2020. Subsequent to March 31, 2017, we purchased one heavy aircraft from a lessor for $17.0 million. Under current conditions, we believe it is unlikely that we will exercise the remaining 2017 purchase options, unless opportunistic conditions arise. Environmental Matters – Legal Matters – Operating Leases non-cancelable month-to-month At March 31, 2017, we had approximately $219.6 million in aggregate commitments under operating leases of which approximately $34.7 million is payable through December 31, 2017. The total lease commitments include $205.0 million for aircraft and $14.6 million for facility lease commitments.

Segment Reporting [Abstract]
Segment Information	10. 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 our total selling, general and administrative expenses that is charged directly to the segment and a small portion that is allocated to that segment. 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. Oil and Gas Segment. Operating revenue from our Oil and Gas segment is derived mainly from contracts that include a fixed monthly rate for a particular model of aircraft, plus a variable payments based on the amount of flight time. Operating costs for the Oil and Gas segment are primarily aircraft operation costs, including costs for pilots and maintenance personnel. We typically operate under fixed-term contracts with our customers, a substantial portion of which are competitively bid. Our fixed-term contracts have terms of one to seven years (subject to provisions permitting early termination by the customers), with payment in U.S. dollars. For the quarters ended March 31, 2017 and 2016, respectively, approximately 53% and 54% of our total operating revenues were generated by our Oil and Gas segment, with approximately 90% and 93% of these revenues from fixed-term customer contracts. The remaining 10% and 7% of these revenues were attributable to work in the spot market and ad hoc flights for contracted customers. Air Medical Segment. We provide Air Medical transportation services for hospitals and emergency service agencies throughout the U.S. As of March 31, 2017, we operated approximately 104 aircraft in 18 states at 72 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 through competitive bidding. For the quarters ended March 31, 2017 and 2016, approximately 41% and 43% of our total operating revenues were generated by our Air Medical segment, respectively. 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. self-pay). Provisions for contractual discounts and estimated uncompensated care for our Air Medical segment (expressed as a percentage of gross segment billings) were as follows: Revenue Quarter Ended March 31, 2017 2016 Gross Air Medical segment billings 100 % 100 % Provision for contractual discounts 70 % 71 % Provision for uncompensated care 4 % 3 % 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 Quarter Ended March 31, 2017 2016 Insurance 70 % 66 % Medicare 20 % 19 % Medicaid 10 % 15 % Self-Pay 0 % 0 % 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. Several of these contracts are issued or renewed based on competitive bidding. These contracts generated approximately 19% and 31% of the segment’s revenues for the quarters ended March 31, 2017 and 2016, respectively. Technical Services Segment. check-in For the three month periods ended March 31, 2017 and 2016, approximately 6% and 3%, respectively, of our total operating revenues were generated by our Technical Services segment. Summarized financial information concerning our reportable operating segments for the quarters ended March 31, 2017 and 2016 is as follows: Quarter Ended March 31, 2017 2016 (Thousands of dollars) Segment operating revenues Oil and Gas $ 71,731 $ 88,437 Air Medical 55,338 70,060 Technical Services 7,549 5,519 Total operating revenues 134,618 164,016 Segment direct expenses (1) Oil and Gas (2) 81,728 91,916 Air Medical 50,842 57,044 Technical Services 4,946 3,594 Total segment direct expenses 137,516 152,554 Segment selling, general and administrative expenses Oil and Gas 1,720 1,528 Air Medical 2,881 2,595 Technical Services 338 224 Total selling, general and administrative expenses 4,939 4,347 Total direct and selling, general and administrative expenses 142,455 156,901 Net segment (loss) profit Oil and Gas (11,717 ) (5,007 ) Air Medical 1,615 10,421 Technical Services 2,265 1,701 Total net segment (loss) profit (7,837 ) 7,115 Other, net (3) 1,064 256 Unallocated selling, general and administrative costs (1) (8,105 ) (7,326 ) Interest expense (8,195 ) (7,533 ) Loss before income taxes $ (23,073 ) $ (7,488 ) (1) Included in segment direct expenses and unallocated selling, general, and administrative costs are the depreciation and amortization expense amounts below: Depreciation and Quarter Ended March 31, 2017 2016 (Thousands of dollars) Segment Direct Expense: Oil and Gas $ 9,862 $ 9,918 Air Medical 5,477 4,256 Technical Services 146 128 Total $ 15,485 $ 14,302 Unallocated SG&A $ 1,360 $ 2,671 (2) Includes Equity in loss of unconsolidated affiliate.

Investment in Variable Interest Entity	11. INVESTMENT IN VARIABLE INTEREST ENTITY We account for our investment in our West African operations 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 March 31, 2017, we had a 49% investment in the common stock of PHI Century Limited (“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 March 31, 2017, we recorded a loss in equity of unconsolidated affiliate of $1.0 million relative to our 49% equity ownership. We had $3.3 million of trade receivables as of March 31, 2017 from PHIC. Our investment in the common stock of PHIC is included in Other assets on our Condensed Consolidated Balance Sheets and was $0.3 million and $0.2 million at March 31, 2017 and December 31, 2016, respectively.

Condensed Consolidating Financial Information	13. CONDENSED CONSOLIDATING FINANCIAL INFORMATION As discussed further in Note 5, 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 our 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”) and the guarantor subsidiaries 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.
