BASIS OF PRESENTATION	'
	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 should be read in conjunction with the consolidated financial statements contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013 and the accompanying notes.
	The Company’s financial results, particularly as they relate to the Company’s Oil and Gas segment, are influenced by seasonal fluctuations as discussed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013. 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.
	Accounting Policies. In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers, which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most current revenue recognition guidance. The standard is effective for public entities for annual and interim periods beginning after December 15, 2016. Early adoption is not permitted. The effects of this standard on our financial position, results of operations and cash flows are not yet known.

	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 (income), 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. Cost, gains, and losses are determined using the specific identification method.

	$15.5 million of our investments at June 30, 2014 and $14.7 million at December 31, 2013 were long-term and included in our Condensed Consolidated Balance Sheets as Restricted investments, as they are securing outstanding letters of credit with maturities beyond one year.

	As of June 30, 2014 and December 31, 2013, we had no investments in a continuous unrealized loss position for more than twelve months.
	From time to time over the periods covered in our financial statements included herein, our investments have experienced net unrealized losses. We consider these declines in market value to be due to market conditions, 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 June 30, 2014 or December 31, 2013. The assessment of whether an investment in a debt security has suffered an other-than-temporary impairment is based on whether we intend to sell, or it is more likely than not we will be required to sell, the debt security before recovery of its amortized costs. Further, if we do not expect to recover the entire amortized cost basis of the debt security, an other-than-temporary impairment is considered to have occurred and it is measured by the present value of cash flows expected to be collected less the amortized cost basis (credit loss). We have determined that we did not have any other-than-temporary impairments relating to credit losses on debt securities for the three months ended June 30, 2014.

	3. REVENUE RECOGNITION AND VALUATION ACCOUNTS
	We have established an allowance for doubtful accounts based upon factors relating to the credit risk of specific customers, current market conditions, and other information. The allowance for doubtful accounts was approximately $1.1 million and $1.0 million at June 30, 2014 and December 31, 2013, respectively.
	Revenues related to emergency 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 $97.6 million and $74.7 million as of June 30, 2014 and December 31, 2013, respectively. The allowance for uncompensated care was $38.8 million and $46.4 million as of June 30, 2014 and December 31, 2013, 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 $2.4 million and $2.6 million for the quarters ended June 30, 2014 and 2013, respectively. The estimated cost of providing charity services was $0.7 million and $1.0 million for the quarters ended June 30, 2014 and 2013, respectively. The value of these services was $4.8 million and $4.4 million for the six months ended June 30, 2014 and 2013 respectively. The estimated cost of providing charity services was $1.3 million and $1.7 million for the six months ended June 30, 2014 and 2013, 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 as a percentage of gross segment accounts receivable are as follows:
		June 30,			December 31,
		2014			2013
	Allowance for Contractual Discounts		52	%		44	%
	Allowance for Uncompensated Care		21	%		27	%
	Our contract in the Middle East requires us to provide multiple services, including helicopter leasing, flight services for helicopter emergency medical service operations, aircraft maintenance, provision of spare parts, insurance coverage for the customer-owned aircraft, training services, and base construction. All services are delivered and earned monthly over a three-year contractual period which began on September 29, 2012. The customer may terminate the contract prior to the end of the contract term by giving ninety days advance notice and paying an early termination fee of $13.5 million. Each of the major services mentioned above qualify 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.
	We have also established valuation reserves related to obsolete and slow-moving spare parts inventory. The inventory valuation reserves were $12.7 million and $12.3 million at June 30, 2014 and December 31, 2013, respectively.

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:
				June 30, 2014
		Total		(Level 1)		(Level 2)
	Investments:
	Money market mutual funds	$	69,048	$	69,048	$	—

	Deferred compensation plan assets		2,109		2,109		—
	Total	$	102,710	$	20,579	$	82,131
	We hold our short-term investments in an investment fund consisting of investment grade money market instruments of governmental and private issuers, which are classified as short-term investments. 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 active. These items may not be traded daily; examples include corporate bonds and U.S. government agencies. There have been no reclassifications for assets between Level 1 and Level 2 investments. We hold no Level 3 investments. Investments included in other assets, which relate to the liability for the 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, 2014 and December 31, 2013. 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 $510.6 million and $323.3 million at June 30, 2014 and December 31, 2013, respectively.

	Senior Notes - During the quarter ended March 31, 2014, we issued $500 million of 5.25% Senior Notes due March 2019 in a private placement under the Securities Act of 1933. Proceeds were approximately $494 million, net of fees and expenses, and a portion of these proceeds were used to retire on March 17, 2014 $292.6 million of our $300 million of previously outstanding 8.625% Senior Notes pursuant to a tender offer, at a total cost of $329.4 million including the tender premium and accrued interest. We subsequently redeemed the remaining $7.4 million of 8.625% Senior Notes on April 16, 2014, at a redemption price of 108.3% of the face amount plus accrued interest. As a result of our repurchase of 8.625% Senior Notes in March 2014, we recorded a pretax charge of $29.2 million in the quarter ended March 31, 2014, which consisted of a $26.1 million tender premium and $3.1 million of unamortized issuance costs. We recorded a pre-tax charge of $0.6 million in the second quarter of 2014 associated with our redemption on April 16, 2014 of the remaining 8.625% Senior Notes not previously tendered. Our repurchase of 8.625% Senior Notes in March 2014 and April 2014 resulted in deferred tax benefits of $11.6 million.
	Our newly-issued 5.25% Senior Notes (the “2019 Notes”) will mature on March 15, 2019, are unconditionally guaranteed on a senior basis by the each of PHI’s domestic subsidiaries, and are the general, unsecured obligations of PHI and the guarantors. Interest is payable semi-annually on March 15 and September 15 of each year, beginning September 15, 2014. 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. Prior to that time, PHI has the option to redeem some or all of the 2019 Notes pursuant to certain “make-whole” provisions or to redeem a portion of the 2019 Notes with the net proceeds of certain specified equity offerings. 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.

	During the second quarter of 2014, we sold or disposed of two light and one medium aircraft previously utilized in our Air Medical segment and one fixed wing aircraft previously utilized for corporate purposes. Cash proceeds totaled $4.2 million, resulting in a loss on the sale of these assets of $0.2 million. These aircraft no longer met our strategic needs.
	During the second quarter of 2013, we sold two heavy aircraft previously utilized in our Oil and Gas segment. The aircraft's carrying value prior to the sale was $20.6 million. These aircraft were sold for $37.0 million, resulting in a gain of $16.4 million recorded in the second quarter of 2013. These aircraft no longer met our strategic needs. In addition we sold an airframe to a charitable organization, which resulted in a loss of $1.7 million.
	During the second quarter of 2013, we recorded an impairment loss for two medium aircraft in our Air Medical segment. The carrying value of these aircraft was $0.8 million. Following a market analysis, it was determined that the current market value of these aircraft was $0.4 million. As a result, we recorded an impairment loss of $0.4 million in the second quarter of 2013.

	9. COMMITMENTS AND CONTINGENCIES
	Commitments – In 2013, we executed a contract to purchase six new heavy helicopters for our Oil and Gas segment, with deliveries scheduled throughout 2014, with an option to purchase six additional heavy aircraft for delivery in 2015 and 2016. One aircraft was delivered in each of the first and second quarters of 2014. In 2014, we exercised our option to purchase six additional new heavy helicopters for our Oil and Gas segment with deliveries scheduled in 2015 and 2016.
	Total aircraft deposits of $13.2 million were included in Other Assets as of June 30, 2014. This amount represents deposits paid by us as required under aircraft purchase contracts.
	As of June 30, 2014, we had options to purchase various aircraft that we currently operate under lease agreements with the aircraft owners. These options will become exercisable at various dates in 2014 through 2019. The aggregate option purchase prices are $71.5 million in 2014, $67.8 million in 2016, $55.7 million in 2017, $127.0 million in 2018, and $64.3 million in 2019. Subject to market conditions and available cash, we currently intend to exercise these options as they become exercisable.
	Environmental Matters – We have recorded an aggregate estimated probable liability of $0.2 million as of June 30, 2014 for environmental response costs. We have conducted environmental surveys of our former Lafayette facility located at the Lafayette Regional Airport, which we vacated in 2001, and have determined that limited soil and groundwater contamination exists at two parcels of land at the former facility. We submitted an assessment report for both sites in 2003, updated it in 2006, and received approvals of our remediation plan from the Louisiana Department of Environmental Quality (“LDEQ”) and Louisiana Department of Natural Resources in 2010 and 2011, respectively. Since such time, we have installed groundwater monitoring wells at these sites, and furnished periodic reports on contamination levels to the LDEQ. Pursuant to our agreement with the LDEQ, we are currently providing samples twice a year for both sites. Based upon our working relationships and agreements with the LDEQ and the results of our ongoing site monitoring, we believe, based on current circumstances, that our ultimate remediation costs for these sites will not be material to our consolidated financial position, results of operations, or cash flows.
	Legal Matters – We are named as a defendant in various legal actions that have arisen in the ordinary course of business and have not been finally adjudicated. In the opinion of management, after considering available defenses and any insurance coverage or indemnification rights, the amount of the liability with respect to these actions will not have a material effect on the Company’s consolidated financial position, results of operations, or cash flows.
	Operating Leases – 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 at certain dates in the lease agreements.
	At June 30, 2014, we had approximately $275.0 million in aggregate commitments under operating leases of which approximately $24.8 million is payable through December 31, 2014. The total lease commitments include $258.5 million for aircraft and $16.5 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 use a combination of factors to identify reportable segments as required by Accounting Standards Codification 280, “Segment Reporting.” The overriding determination of our segments is based on how our Chief Executive Officer evaluates our results of operations. The underlying factors include customer bases, types of service, operational management, physical locations, and underlying economic characteristics of the types of work we perform.
	A segment’s operating profit 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 are charged directly to the segment and a portion that is allocated. Direct charges represent the vast majority of the segment’s selling, general and administrative expenses. Allocated selling, general and administrative expenses are based primarily on total segment direct expenses as a percentage of total direct expenses. Unallocated overhead consists primarily of corporate selling, general and administrative expenses that we do not allocate to the reportable 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 and/or equipment to offshore platforms in the Gulf of Mexico. Our customers include Shell Oil Company, BP America Production Company, ExxonMobil Production Co., and ConocoPhillips Company, with whom we have worked for 30 or more years, and ENI Petroleum, with whom we have worked for more than 15 years. At June 30, 2014, we operated 170 aircraft in this 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 rate for flight time. A small portion of our Oil and Gas segment revenue is derived from providing services on an “ad hoc” basis. Operating costs for our Oil and Gas segment are primarily aircraft operations costs, including costs for pilots and maintenance personnel. Total fuel cost is included in direct expense and any reimbursement of a portion of these costs above a contracted per-gallon amount is included in revenue. For the quarters ended June 30, 2014 and 2013, approximately 60% and 62% of our total operating revenues were generated by our Oil and Gas operations. Our Oil and Gas operations generated approximately 62% of our total operating revenue for the six months ended June 30, 2014 and 2013.
	Air Medical Segment. Our Air Medical operations are headquartered in Phoenix, Arizona, where we maintain significant separate facilities and administrative staff dedicated to this segment. Those costs are charged directly to our Air Medical segment.
	As of June 30, 2014, 99 aircraft were assigned to our Air Medical segment. At such date, we operated approximately 91 aircraft domestically, providing air medical transportation services for hospitals and emergency service agencies in 18 states at 72 separate locations. We also provide air medical transportation services for a customer overseas. For this program, we have deployed nine aircraft at five locations, with seven aircraft generating revenues as of June 30, 2014. 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 contracts and 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 June 30, 2014 and 2013, approximately 37% of our total operating revenues were generated by our Air Medical operations. For the six months ended June 30, 2014 and 2013, approximately 36% of our total operating revenues were generated by our Air Medical operations.
	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 Medicaid, Medicare or private insurance or directly by the transported patient. Revenues are recorded net of 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 of Medicaid, Medicare, insurance and self-pay). 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. The allowance percentages calculated are applied to the payor categories, and the necessary adjustments are made to the revenue allowance. The allowance for contractual discounts was $97.6 million and $66.7 million as of June 30, 2014 and June 30, 2013, respectively. The allowance for uncompensated care was $38.8 million and $45.3 million as of June 30, 2014 and June 30, 2013, respectively.
	Provisions for contractual discounts and estimated uncompensated care for Air Medical operations as a percentage of gross segment billings are as follows:
			Revenue
			Quarter Ended						Six Months Ended
			June 30,						June 30,
			2014			2013			2014			2013
	Provision for contractual discounts			70	%		60	%		69	%		60	%
	Provision for uncompensated care			4	%		9	%		4	%		9	%
	These percentages are affected by 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, does not increase proportionately with rate increases.
	Net revenue attributable to Insurance, Medicare, Medicaid, and Self-Pay as a percentage of net Air Medical revenues are as follows:
			Quarter Ended						Six Months Ended
			June 30,						June 30,
			2014			2013			2014			2013
	Insurance			74	%		73	%		73	%		72	%
	Medicare			18	%		18	%		19	%		19	%
	Medicaid			7	%		8	%		7	%		8	%
	Self-Pay			1	%		1	%		1	%		1	%
	We also have a limited number of contracts with hospitals under which we receive a fixed monthly rate for aircraft availability and an hourly rate for flight time. Those contracts generated approximately 39% and 38% of the segment’s revenues for the quarters ended June 30, 2014 and 2013, respectively. For the six months ended June 30, 2014 and 2013, these contracts generated approximately 40% and 39% of the segment’s revenues.
	Technical Services Segment. Our Technical Services segment provides helicopter repair and overhaul services for our customers that own their own aircraft. Costs associated with these services are primarily labor, and customers are generally billed at a percentage above cost.
	For both the three and the six-month periods ended June 30, 2014 and 2013, approximately 2% and 1%, respectively, of our total operating revenues were generated by our Technical Services operations.
	Summarized financial information concerning our reportable operating segments for the quarters and six months ended June 30, 2014 and 2013 is as follows:

	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 June 30, 2014, 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 June 30, 2014 and 2013, we recorded a loss in equity of unconsolidated affiliate of $0. 1 million and $0.6 million, relative to our 49% equity ownership, respectively. For the six months ended June 30, 2014 and 2013, we recorded a loss in equity of unconsolidated affiliate of $0.1 million and $1.1 million relative to our 49% equity ownership, respectively. In addition, we had $4.7 million of trade receivables and $1.8 million of accrued liabilities as of June 30, 2014 from PHIC. We had $3.5 million of trade receivables and a $1.9 million of accrued liabilities as of December 31, 2013. The trade receivables are included in Accounts receivable - trade on our Condensed Consolidated Balance Sheets. The accrued liabilities are included in Accrued and other current liabilities on our Condensed Consolidated Balance Sheets. Our investment in the common stock of PHIC is included in Other assets on our Condensed Consolidated Balance Sheets and was $-0- million at June 30, 2014 and December 31, 2013.

Accounting Policies	'
	Accounting Policies. In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers, which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most current revenue recognition guidance. The standard is effective for public entities for annual and interim periods beginning after December 15, 2016. Early adoption is not permitted. The effects of this standard on our financial position, results of operations and cash flows are not yet known.
