	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, 2012 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, 2012. 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.

	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 income (loss) until realized. These gains and losses are reflected as a separate component of shareholders’ equity in our Condensed Consolidated Balance Sheets and our Condensed Consolidated Statements of Shareholders’ Equity. Cost, gains, and losses are determined using the specific identification method.

	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 September 30, 2013 or December 31, 2012. The assessment of whether an investment in a debt security has suffered an other-than-temporary impairment is based on whether the Company has the intent to sell or more likely than not will be required to sell the debt security before recovery of its amortized costs. Further, if the Company does 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 quarter and nine months ended September 30, 2013.

	3. REVENUE RECOGNITION AND VALUATION ACCOUNTS
	We have established an allowance for doubtful accounts based upon factors surrounding the credit risk of specific customers, current market conditions, and other information. The allowance for doubtful accounts was approximately $0.1 million at September 30, 2013 and December 31, 2012.
	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 $67.4 million and $54.6 million as of September 30, 2013 and December 31, 2012, respectively. The allowance for uncompensated care was $55.5 million and $48.0 million as of September 30, 2013 and December 31, 2012, 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 $2.1 million and $1.8 million for the quarters ended September 30, 2013 and 2012, respectively. The estimated cost of providing charity services was $1.0 million and $0.5 million for the quarters ended September 30, 2013 and 2012, respectively. The value of these services was $6.5 million and $4.0 million for the nine months ended September 30, 2013 and 2012, respectively. The estimated cost of providing charity services was $2.5 million and $1.4 million for the nine months ended September 30, 2013 and 2012, 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 segment’s total expenses divided by gross patient service revenue.
	The allowance for contractual discounts and estimated uncompensated care as a percentage of gross accounts receivable are as follows:
		September 30,			December 31,
		2013			2012
	Allowance for Contractual Discounts		39	%		38	%
	Allowance for Uncompensated Care		32	%		33	%
	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 $11.9 million and $12.4 million at September 30, 2013 and December 31, 2012, respectively.

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:
				September 30, 2013
		Total		(Level 1)		(Level 2)
	Investments:
	Money Market Mutual Funds	$	22,554	$	22,554	$	—

	Deferred compensation plan assets		2,687		2,687		—
	Total	$	67,973	$	32,503	$	35,470
	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 transfers 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 all had fair values approximating their carrying amounts at September 30, 2013 and December 31, 2012. Our determination of the estimated fair value of our Senior Notes and our revolving credit facility 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 $313.5 million and $320.3 million at September 30, 2013 and December 31, 2012, respectively.

	Asset disposal and impairments - During the third quarter of 2013, we sold one light aircraft previously utilized in our Oil and Gas segment and miscellaneous equipment with a carrying value of $1.2 million. Cash proceeds totaled $2.6 million, resulting in a gain on the sale of these assets of $1.4 million. During the nine months ended September 30, 2013, we sold, in addition to these above-described properties, two heavy previously utilized in our Oil and Gas segment. The carrying value prior to the sale was $20.6 million. These assets 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.
	We also recorded an impairment loss in the nine months ended September 30, 2013 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 for these aircraft was $0.4 million. As a result, we recorded an impairment loss of $0.4 million.

	9. COMMITMENTS AND CONTINGENCIES
	Commitments – In the third quarter of 2013, we entered into a contract to purchase six new light helicopters for our Air Medical segment with deliveries scheduled for the third and fourth quarters of 2013. Three aircraft were delivered in the third quarter and the remaining three are scheduled for delivery in the fourth quarter. The aggregate acquisition cost of the remaining three aircraft is $7.6 million.
	In the first quarter of 2013, we agreed to purchase two customer-owned light helicopters for our Air Medical segment, to be completed in the fourth quarter of 2013. The aggregate acquisition cost is $3.6 million.
	Total aircraft deposits of $7.5 million were included in Other Assets as of September 30, 2013. This amount represents deposits required under aircraft purchase contracts.
	As of September 30, 2013, we had options to purchase aircraft under lease becoming exercisable in 2013 through 2019. The aggregate option purchase prices are $14.9 million in 2013, $103.0 million in 2014, $67.8 million in 2016, $55.2 million in 2017, $84.9 million in 2018, and $19.5 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 September 30, 2013 for environmental response costs. The Company has conducted environmental surveys of its former Lafayette facility located at the Lafayette Regional Airport, which it vacated in 2001, and has determined that limited soil and groundwater contamination exists at the facility. The Company has installed groundwater monitoring wells at the facility and periodically monitors and reports on the contamination to the Louisiana Department of Environmental Quality (“LDEQ”). The Company previously submitted a Risk Evaluation Corrective Action Plan Standard Site Assessment Report to the LDEQ fully delineating the extent and type of contamination and updated the Report to include additional analytical data in April 2006. LDEQ reviewed the Assessment Report and requested a Corrective Action Plan from the Company. LDEQ approved the Corrective Action Plan (“CAP”) for the remediation of the former PHI plant location on August 23, 2010. All Louisiana Department of Natural Resources approvals were received and the project began on May 16, 2011. Initial work took three weeks. Groundwater sampling that was performed during December 2011, March 2012, and September 2012 was evaluated to determine the effectiveness of remediation performed to date and whether additional remediation will be necessary. Based upon that review, a second round of sampling in one of the two source areas was performed during the fourth quarter of 2012. Based upon the May 2003 Site Assessment Report, the April 2006 update, ongoing monitoring, and the August 2010 CAP, the Company believes the (i) total cost for this project will remain substantially below the current environmental reserve and (ii) ultimate remediation costs for the former Lafayette facility will not be material to its consolidated financial position, results of operations, or cash flows.
	Legal Matters – The Company is 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, 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.
	On December 31, 2009, the Office and Professional Employees International Union (“OPEIU”), the union representing the Company’s domestic pilots, sued the Company in United States District Court for the Western District of Louisiana asserting that its acceptance in 2009 of the terms and conditions of employment for the Company’s pilots initially implemented by the Company prior to a 2006 strike has created a binding collective bargaining agreement and that the Company has inappropriately made unilateral revisions to those terms, including failing to pay a retention bonus. The Court administratively stayed this case pending the completion of appellate briefing in two other litigations between the parties that have since been resolved in the Company’s favor. By Order dated April 26, 2012, the District Court invited PHI to file a motion to dismiss the OPEIU’s claims. PHI filed such a motion to dismiss the OPEIU’s claims on May 11, 2012, and the Court dismissed all claims against PHI without prejudice for lack of jurisdiction to award the equitable relief sought in the complaint, entering a final judgment on October 15, 2012. The OPEIU appealed this decision to the U.S Court of Appeals for the Fifth Circuit. By order dated August 8, 2013, the court of appeals affirmed the trial court’s order dismissing all claims against PHI. The Union did not seek rehearing from the appellate court. The time in which the Union could seek a writ of certiorari from the United States Supreme Court expired on November 6, 2013. PHI has not been served with a petition as of this date. If no such petition has been filed by November 6, 2013, then the matter is concluded in PHI’s favor.
	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 September 30, 2013, we had approximately $284.3 million in aggregate commitments under operating leases of which approximately $11.7 million is payable through December 31, 2013. The total lease commitments include $266.3 million for aircraft and $18.0 million for facility lease commitments.

Segment Reporting [Abstract]	'
SEGMENT INFORMATION	'
	10. SEGMENT INFORMATION
	PHI is primarily a provider of helicopter 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 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. We currently operate 169 aircraft in this segment.
	Operating revenue from the 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. Operating costs for the 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 September 30, 2013 and 2012, approximately 63% and 67%, respectively, of our total operating revenues were generated by our Oil and Gas segment. Our Oil and Gas segment generated approximately 63% and 67% of our total operating revenue for the nine months ended September 30, 2013 and 2012, respectively.
	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 the Air Medical segment.
	As of September 30, 2013, 102 aircraft were assigned to our Air Medical segment. We currently operate approximately 87 aircraft domestically, providing air medical transportation services for hospitals and emergency service agencies in 18 states at 71 separate locations. We also provide air medical transportation services for a customer in the Middle East. For this program, we currently intend, based on present conditions, to deploy eight aircraft at six locations once all aircraft are operational, which we expect to occur in the fourth quarter of 2013. Our Air Medical segment operates primarily under the independent provider model and, to a lesser extent, under the hospital-based 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 hospital-based model, we contract directly with the hospital to provide their transportation services, with the contracts typically awarded on a competitive bid basis. For the quarters ended September 30, 2013 and 2012, approximately 36% and 32% of our total operating revenues were generated by our Air Medical segment, respectively. For the nine months ended September 30, 2013 and 2012, approximately 36% and 32% 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 loaded mile, regardless of aircraft model. Revenues are recorded net of contractual allowances under agreements with third party payors and estimated uncompensated care when the services are provided. Contractual allowances and uncompensated care are estimated based on historical collection experience by payor category. The main payor categories are Insurance, Medicare, Medicaid, 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 $67.4 million and $57.1 million as of September 30, 2013 and September 30, 2012, respectively. The allowance for uncompensated care was $55.5 million and $51.3 million as of September 30, 2013 and September 30, 2012, respectively.
	Provisions for contractual discounts and estimated uncompensated care for Air Medical operations as a percentage of gross billings are as follows:
			Revenue
			Quarter Ended						Nine Months
									Ended
			September 30,						September 30,
			2013			2012			2013			2012
	Provision for contractual discounts			62	%		50	%		60	%		56	%
	Provision for uncompensated care			8	%		17	%		9	%		11	%
	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						Nine Months Ended
			September 30,						September 30,
			2013			2012			2013			2012
	Insurance			75	%		66	%		73	%		68	%
	Medicare			17	%		25	%		18	%		22	%
	Medicaid			7	%		8	%		8	%		9	%
	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 38% and 18% of the segment’s revenues for the quarters ended September 30, 2013 and 2012, respectively. For the nine months ended September 30, 2013 and 2012, these contracts generated approximately 38% and 19% of the segment’s revenues. The increase is primarily due to the expansion of operations under our 2012 contract in the Middle East, which is also structured as a hospital contract, but had minimal revenue in the third quarter 2012.
	Technical Services Segment. Our Technical Services segment provides helicopter repair and overhaul services for customer owned aircraft. Costs associated with these services are primarily labor, and customers are generally billed at a percentage above cost.
	Approximately 1% of our total operating revenues for the quarters and nine months ended September 30, 2013 and September 30, 2012 were generated by our Technical Services segment.
	Summarized financial information concerning our reportable operating segments for the quarters and nine months ended September 30, 2013 and 2012 is as follows:

	11. INVESTMENT IN VARIABLE INTEREST ENTITY
	A variable interest entity is 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 September 30, 2013, 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 nine months ended September 30, 2013, we recorded a loss in equity of unconsolidated affiliate of $0.9 million relative to our 49% equity ownership. In addition, we had $5.6 million of Trade receivables and a $1.0 million note receivable outstanding as of September 30, 2013 from PHIC. The note receivable is included in Other assets on our Condensed Consolidated Balance Sheet. Our investment in the common stock of PHIC is included in Other assets on our Condensed Consolidated Balance Sheet and was $(1.7) million at September 30, 2013. Included in Operating revenues for nine months ended September 30, 2013 is $2.0 million of revenues from services provided to PHIC.
