	NOTE 1 — BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES
	Reporting Entity
	HCA Holdings, Inc. is a holding company whose affiliates own and operate hospitals and related health care entities. The term “affiliates” includes direct and indirect subsidiaries of HCA Holdings, Inc. and partnerships and joint ventures in which such subsidiaries are partners. At September 30, 2014, these affiliates owned and operated 165 hospitals, 113 freestanding surgery centers and provided extensive outpatient and ancillary services. HCA Holdings, Inc.’s facilities are located in 20 states and England. The terms “Company,” “HCA,” “we,” “our” or “us,” as used herein and unless otherwise stated or indicated by context, refer to HCA Holdings, Inc. and its affiliates. The terms “facilities” or “hospitals” refer to entities owned and operated by affiliates of HCA and the term “employees” refers to employees of affiliates of HCA.
	Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles for complete consolidated financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included and are of a normal and recurring nature.
	The majority of our expenses are “costs of revenues” items. Costs that could be classified as general and administrative would include our corporate office costs, which were $71 million and $76 million for the quarters ended September 30, 2014 and 2013, respectively, and $206 million and $207 million for the nine months ended September 30, 2014 and 2013, respectively. Operating results for the quarter and the nine months ended September 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014. For further information, refer to the consolidated financial statements and footnotes thereto included in our annual report on Form 10-K for the year ended December 31, 2013.

	Revenues are recorded during the period the health care services are provided, based upon the estimated amounts due from the patients and third-party payers. Third-party payers include federal and state agencies (under Medicare, Medicaid and other programs), managed care health plans (includes the health insurance exchanges, beginning with the first quarter of 2014), commercial insurance companies and employers. Estimates of contractual allowances under managed care health plans are based upon the payment terms specified in the related contractual agreements. Revenues related to uninsured patients and copayment and deductible amounts for patients who have health care coverage may have discounts applied (uninsured discounts and contractual discounts). We also record a provision for doubtful accounts related to uninsured accounts to record the net self pay revenues at the estimated amounts we expect to collect. Our revenues from third-party payers and the uninsured for the quarters and nine months ended September 30, 2014 and 2013 are summarized in the following table (dollars in millions):

	During the quarter ended September 30, 2014, we recorded two changes in estimates which had the net effect of increasing revenues $26 million. We recorded $94 million, or $0.13 per diluted share, of Medicare revenues as the estimated settlement amount for certain claims denied by Recovery Audit Contractors (“RAC”) entities conducting reviews on behalf of the Centers for Medicare and Medicaid Services (“CMS”) and currently in the pending appeals process. CMS is offering an administrative agreement to providers willing to withdraw their pending appeals in exchange for a timely partial payment (generally, 68% of the claim amount, subject to certain adjustments). We also recorded a reduction of $68 million, or $0.09 per diluted share, to Medicaid revenues related to the Texas Medicaid Waiver Program. On October 1, 2014, the Texas Health and Human Services Commission (“THHSC”) issued a notice to hospitals participating in the Texas Medicaid Waiver Program. According to the notice, a review conducted by CMS identified certain local government/hospital affiliations it believes may be inconsistent with the waiver. As a result of these findings, CMS notified THHSC that it is deferring the federal portion of the Medicaid payments associated with these affiliations while it completes its review.
	Recent Pronouncements
	In May 2014, the Financial Accounting Standards Board and the International Accounting Standards Board issued a final, converged, principles-based standard on revenue recognition. Companies across all industries will use a five-step model to recognize revenue from customer contracts. The new standard, which replaces nearly all existing United States Generally Accepted Accounting Principles (“US GAAP”) and International Financial Reporting Standards revenue recognition guidance, will require significant management judgment in addition to changing the way many companies recognize revenue in their financial statements. The standard is effective for public entities for annual and interim periods beginning after December 15, 2016. Early adoption is not permitted under US GAAP. We are evaluating the effects the adoption of this standard will have on our financial statements and financial disclosures.

	NOTE 2 — ACQUISITIONS AND DISPOSITIONS
	During the nine months ended September 30, 2014, we paid $14 million to acquire a hospital and $83 million to acquire other nonhospital health care entities. During the nine months ended September 30, 2013, we paid $317 million and recorded goodwill and identifiable intangible assets of $176 million and $125 million, respectively, related to the acquisitions of nonhospital health care entities and $146 million related to the acquisition of three hospitals.
	During the nine months ended September 30, 2014, we received proceeds of $38 million and recognized net pretax gains of $20 million related to sales of real estate and other investments. During the nine months ended September 30, 2013, we received proceeds of $31 million and recognized net pretax losses of $13 million related to sales of a hospital facility and real estate and other investments.

	NOTE 3 — INCOME TAXES
	The IRS Examination Division began an audit of HCA Holdings, Inc.’s 2011 and 2012 federal income tax returns during 2014. We are also subject to examination by state and foreign taxing authorities.
	Our liability for unrecognized tax benefits was $503 million, including accrued interest of $43 million, as of September 30, 2014 ($462 million and $30 million, respectively, as of December 31, 2013). Unrecognized tax benefits of $180 million ($160 million as of December 31, 2013) would affect the effective rate, if recognized. The provision for income taxes reflects $3 million and $7 million ($2 million and $4 million, respectively, net of tax) of interest expense related to taxing authority examinations for the quarters ended September 30, 2014 and 2013, respectively. The provision for income taxes reflects $11 million ($7 million, net of tax) of interest expense related to taxing authority examinations and $8 million ($5 million, net of tax) of reductions in interest expense related to taxing authority examinations for the nine months ended September 30, 2014 and 2013, respectively.
	Depending on the completion of examinations by federal, state or foreign taxing authorities, the resolution of any tax disputes, or the expiration of statutes of limitation for specific taxing jurisdictions, we believe it is reasonably possible our liability for unrecognized tax benefits may significantly increase or decline within the next 12 months. However, we are currently unable to estimate the range of any possible change.

	Scheduled maturities of investments in debt securities at September 30, 2014 were as follows (dollars in millions):

	The average expected maturity of the investments in debt securities at September 30, 2014 was 4.1 years, compared to the average scheduled maturity of 6.1 years. Expected and scheduled maturities may differ because the issuers of certain securities have the right to call, prepay or otherwise redeem such obligations prior to their scheduled maturity date.

NOTE 6 — FINANCIAL INSTRUMENTS

Interest Rate Swap Agreements

We have entered into interest rate swap agreements to manage our exposure to fluctuations in interest rates. These swap agreements involve the exchange of fixed and variable rate interest payments between two parties based on common notional principal amounts and maturity dates. Pay-fixed interest rate swaps effectively convert LIBOR indexed variable rate obligations to fixed interest rate obligations. The interest payments under these agreements are settled on a net basis. The net interest payments, based on the notional amounts in these agreements, generally match the timing of the related liabilities for the interest rate swap agreements which have been designated as cash flow hedges. The notional amounts of the swap agreements represent amounts used to calculate the exchange of cash flows and are not our assets or liabilities. Our credit risk related to these agreements is considered low because the swap agreements are with creditworthy financial institutions.

The following table sets forth our interest rate swap agreements, which have been designated as cash flow hedges, at September 30, 2014 (dollars in millions):

Credit-risk-related Contingent Features

We have agreements with each of our derivative counterparties that contain a provision where we could be declared in default on our derivative obligations if repayment of the underlying indebtedness is accelerated by the lender due to our default on the indebtedness. As of September 30, 2014, we have not been required to post any collateral related to these agreements. If we had breached these provisions at September 30, 2014, we would have been required to settle our obligations under the agreements at their aggregate, estimated termination value of $224 million.

Fair Value Disclosures [Abstract]	'
Assets and Liabilities Measured at Fair Value	'
	NOTE 7 — ASSETS AND LIABILITIES MEASURED AT FAIR VALUE
	Accounting Standards Codification 820, Fair Value Measurements and Disclosures (“ASC 820”) emphasizes fair value is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement should be determined based on the assumptions market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, ASC 820 establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy).
	Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input significant to the fair value measurement in its entirety. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.
	Cash Traded Investments
	Our cash traded investments are generally classified within Level 1 or Level 2 of the fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. Certain types of cash traded instruments are classified within Level 3 of the fair value hierarchy because they trade infrequently and therefore have little or no price transparency. The valuation of these securities involves management’s judgment, after consideration of market factors and the absence of market transparency, market liquidity and observable inputs. Our valuation models derived fair market values compared to tax-equivalent yields of other securities of similar credit worthiness and similar effective maturities.
	Derivative Financial Instruments
	We have entered into interest rate swap agreements to manage our exposure to fluctuations in interest rates. The valuation of these instruments is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. We incorporate credit valuation adjustments to reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements.
	Although we determined the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with our derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by us and our counterparties. We assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions, and at September 30, 2014 and December 31, 2013, we determined the credit valuation adjustments were not significant to the overall valuation of our derivatives.
	The following tables summarize our assets and liabilities measured at fair value on a recurring basis as of September 30, 2014 and December 31, 2013, aggregated by the level in the fair value hierarchy within which those measurements fall (dollars in millions):

Contingencies and Legal Claim Costs	'

	NOTE 9 — CONTINGENCIES AND LEGAL CLAIM COSTS

	We operate in a highly regulated and litigious industry. As a result, various lawsuits, claims and legal and regulatory proceedings have been and can be expected to be instituted or asserted against us. We are also subject to claims and suits arising in the ordinary course of business, including claims for personal injuries or wrongful restriction of, or interference with, physicians’ staff privileges. In certain of these actions the claimants may seek punitive damages against us which may not be covered by insurance. The resolution of any such lawsuits, claims or legal and regulatory proceedings could have a material, adverse effect on our results of operations or financial position.

	Government Investigations, Claims and Litigation

	Health care companies are subject to numerous investigations by various governmental agencies. Further, under the federal False Claims Act (“FCA”), private parties have the right to bring qui tam, or “whistleblower,” suits against companies that submit false claims for payments to, or improperly retain overpayments from, the government. Some states have adopted similar state whistleblower and false claims provisions. Certain of our individual facilities have received, and from time to time, other facilities may receive, government inquiries from, and may be subject to investigation by, federal and state agencies. Depending on whether the underlying conduct in these or future inquiries or investigations could be considered systemic, their resolution could have a material, adverse effect on our financial position, results of operations and liquidity.

	As initially disclosed in 2010, the Civil Division of the Department of Justice (“DOJ”) has contacted the Company in connection with its nationwide review of whether, in certain cases, hospital charges to the federal government relating to implantable cardio-defibrillators (“ICDs”) met the CMS criteria. In connection with this nationwide review, the DOJ has indicated that it will be reviewing certain ICD billing and medical records at 95 HCA hospitals; the review covers the period from October 2003 to the present. In August 2012, HCA, along with non-HCA hospitals across the country subject to the DOJ’s review, received from the DOJ a proposed framework for resolving the DOJ’s review of ICDs. The Company is cooperating in the review. The review could potentially give rise to claims against the Company under the federal FCA or other statutes, regulations or laws. At this time, we cannot predict what effect, if any, this review or any resulting claims could have on the Company.

	In July 2012, the Civil Division of the U.S. Attorney’s Office in Miami requested information on reviews assessing the medical necessity of interventional cardiology services provided at any Company facility (other than peer reviews). The Company is cooperating with the government’s request and has produced medical records associated with particular reviews at eight hospitals, located primarily in Florida. At this time, we cannot predict what effect, if any, the request or any resulting claims, including any potential claims under the federal FCA, other statutes, regulations or laws, could have on the Company.

	On April 2, 2014, the UK Competition and Markets Authority (“Authority”) issued a final report on its investigation of the private health care market in London. It concluded, among other things, that many private hospitals face little competition in central London, and that there are high barriers to entry. As part of its remedies package, the Authority ordered HCA to sell either: (a) its London Bridge and Princess Grace hospitals; or (b) its Wellington Hospital, including the Hospital Platinum Medical Centre. It also imposed other remedial conditions on HCA and other private health care providers, including: regulation of incentives to referring physicians; increased access to information about fees and performance; and restrictions on future arrangements between private providers and National Health Service private patient units. HCA disagrees with the Authority’s assessment of the competitive conditions for hospitals in London, as well as its proposed divestiture remedy, and has appealed the decision to the Competition Appeal Tribunal. The appeal is expected to be decided in 2015.



	Securities Class Action Litigation

	On October 28, 2011, a shareholder action, Schuh v. HCA Holdings, Inc. et al., was filed in the United States District Court for the Middle District of Tennessee seeking monetary relief. The case sought to include as a class all persons who acquired the Company’s stock pursuant or traceable to the Company’s Registration Statement issued in connection with the March 9, 2011 initial public offering. The lawsuit asserted a claim under Section 11 of the Securities Act of 1933 against the Company, certain members of the board of directors, and certain underwriters in the offering. It further asserted a claim under Section 15 of the Securities Act of 1933 against the same members of the board of directors. The action alleged various deficiencies in the Company’s disclosures in the Registration Statement. Subsequently, two additional class action complaints, Kishtah v. HCA Holdings, Inc. et al. and Daniels v. HCA Holdings, Inc. et al., setting forth substantially similar claims against substantially the same defendants were filed in the same federal court on November 16, 2011 and December 12, 2011, respectively. All three of the cases were consolidated. On May 3, 2012, the court appointed New England Teamsters & Trucking Industry Pension Fund as Lead Plaintiff for the consolidated action. On July 13, 2012, the lead plaintiff filed an amended complaint asserting claims under Sections 11 and 12(a)(2) of the Securities Act of 1933 against the Company, certain members of the board of directors, and certain underwriters in the offering. It further asserts a claim under Section 15 of the Securities Act of 1933 against the same members of the board of directors and Hercules Holdings II, LLC, a majority shareholder of the Company at the time of the initial public offering. The consolidated complaint alleges deficiencies in the Company’s disclosures in the Registration Statement and Prospectus relating to: (1) the accounting for the Company’s 2006 recapitalization and 2010 reorganization; (2) the Company’s failure to maintain effective internal controls relating to its accounting for such transactions; and (3) the Company’s Medicare and Medicaid revenue growth rates. The Company and other defendants moved to dismiss the amended complaint on September 11, 2012. The Court granted the motion in part on May 28, 2013. The action proceeded to discovery on the remaining claims. The plaintiffs’ motion for class certification was granted on September 22, 2014. The court certified a class consisting of all persons that acquired HCA stock on or before October 28, 2011 (the date of the lawsuit) pursuant to the Registration Statement issued in connection with the March 9, 2011 initial public offering. We have requested permission from the trial court of appeals to immediately appeal this ruling.

	In addition to the above described shareholder class actions, on December 8, 2011, a federal shareholder derivative action, Sutton v. Bracken, et al., putatively initiated in the name of the Company, was filed in the United States District Court for the Middle District of Tennessee against certain officers and present and former directors of the Company seeking monetary relief. The action alleges breaches of fiduciary duties by the named officers and directors in connection with the accounting and earnings claims set forth in the shareholder class actions. Setting forth substantially similar claims against substantially the same defendants, an additional federal derivative action, Schroeder v. Bracken, et al., was filed in the United States District Court for the Middle District of Tennessee on December 16, 2011, and a state derivative action, Bagot v. Bracken, et al., was filed in Tennessee state court in the Davidson County Circuit Court on December 20, 2011. The federal derivative actions were consolidated in the Middle District of Tennessee and stayed pending developments in the shareholder class actions. The state derivative action had also been stayed pending developments in the shareholder class actions, but that stay has expired. The plaintiff in the state derivative action subsequently filed an amended complaint on September 9, 2013 that added additional allegations made in the shareholder class actions. On September 24, 2013, an additional state derivative action, Steinberg v. Bracken, et al., was filed in Tennessee state court in the Davidson County Circuit Court. This action against our board of directors has been consolidated with the earlier filed state derivative action. The plaintiffs in the consolidated action filed a consolidated complaint on December 4, 2013. The Company has filed a motion to again stay the state derivative action pending developments in the class action, but the Court has not yet acted on that motion.



	Health Midwest Litigation

	In October 2009, the Health Care Foundation of Greater Kansas City, a nonprofit health foundation, filed suit against HCA Inc. in the Circuit Court of Jackson County, Missouri and alleged that HCA did not fund the level of capital expenditures and uncompensated care agreed to in connection with HCA’s purchase of hospitals from Health Midwest in 2003. The central issue in the case was whether HCA’s construction of new hospitals counted towards its $450 million five-year capital commitments. In addition, the plaintiff alleged that HCA did not make its required capital expenditures in a timely fashion. On January 24, 2013, the Court ruled in favor of the plaintiff and awarded at least $162 million. The Court also ordered a court-supervised accounting of HCA’s capital expenditures, as well as of expenditures on charity and uncompensated care during the ten years following the purchase. The Court also indicated it would award plaintiff attorneys fees, which the parties have stipulated are approximately $12 million for the trial phase. HCA recorded $175 million of legal claim costs in the fourth quarter of 2012 related to this ruling, and consistent with the judge’s order, has been accruing interest on that sum at 9% per annum. On April 25, 2014, the parties stipulated to an additional $78 million shortfall relating to the capital expenditures issue. HCA recorded $78 million of legal claims costs in the first quarter of 2014 as a result of the stipulation, and is accruing interest on that amount at 9% per annum. Pursuant to the terms of the stipulation, the parties have preserved their respective rights to contest the judge’s underlying ruling, whether through motions in the trial court or on appeal. The accounting for charity and other uncompensated care is ongoing. Final judgment in the case currently is not anticipated before 2015. At this time, we cannot predict what effect, if any, the final judgment could have on the Company. HCA plans to appeal the trial court’s ruling on the breach of contract claim and order for the accounting once the trial court rules on the accounting and enters judgment.

	We operate in one line of business, which is operating hospitals and related health care entities. Effective January 1, 2013, we reorganized our operational groups into two geographically organized groups: the National and American Groups. The National Group includes 81 hospitals located in Alaska, California, Florida, southern Georgia, Idaho, Indiana, northern Kentucky, Nevada, New Hampshire, South Carolina, Utah and Virginia, and the American Group includes 77 hospitals located in Colorado, northern Georgia, Kansas, southern Kentucky, Louisiana, Mississippi, Missouri, Oklahoma, Tennessee and Texas. We also operate seven hospitals in England, and these facilities are included in the Corporate and other group.
	Adjusted segment EBITDA is defined as income before depreciation and amortization, interest expense, losses (gains) on sales of facilities, losses on retirement of debt, legal claim costs, income taxes and net income attributable to noncontrolling interests. We use adjusted segment EBITDA as an analytical indicator for purposes of allocating resources to geographic areas and assessing their performance. Adjusted segment EBITDA is commonly used as an analytical indicator within the health care industry, and also serves as a measure of leverage capacity and debt service ability. Adjusted segment EBITDA should not be considered as a measure of financial performance under generally accepted accounting principles, and the items excluded from adjusted segment EBITDA are significant components in understanding and assessing financial performance. Because adjusted segment EBITDA is not a measurement determined in accordance with generally accepted accounting principles and is thus susceptible to varying calculations, adjusted segment EBITDA, as presented, may not be comparable to other similarly titled measures of other companies. The geographic distributions of our revenues, equity in earnings of affiliates, adjusted segment EBITDA and depreciation and amortization for the quarters and nine months ended September 30, 2014 and 2013 are summarized in the following table (dollars in millions):

Basis of Presentation	'
	Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles for complete consolidated financial statements. In the opinion of management, all adjustments considered necessary for a fair presentation have been included and are of a normal and recurring nature.
	The majority of our expenses are “costs of revenues” items. Costs that could be classified as general and administrative would include our corporate office costs, which were $71 million and $76 million for the quarters ended September 30, 2014 and 2013, respectively, and $206 million and $207 million for the nine months ended September 30, 2014 and 2013, respectively. Operating results for the quarter and the nine months ended September 30, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014. For further information, refer to the consolidated financial statements and footnotes thereto included in our annual report on Form 10-K for the year ended December 31, 2013.

	Revenues are recorded during the period the health care services are provided, based upon the estimated amounts due from the patients and third-party payers. Third-party payers include federal and state agencies (under Medicare, Medicaid and other programs), managed care health plans (includes the health insurance exchanges, beginning with the first quarter of 2014), commercial insurance companies and employers. Estimates of contractual allowances under managed care health plans are based upon the payment terms specified in the related contractual agreements. Revenues related to uninsured patients and copayment and deductible amounts for patients who have health care coverage may have discounts applied (uninsured discounts and contractual discounts). We also record a provision for doubtful accounts related to uninsured accounts to record the net self pay revenues at the estimated amounts we expect to collect. Our revenues from third-party payers and the uninsured for the quarters and nine months ended September 30, 2014 and 2013 are summarized in the following table (dollars in millions):


		Quarter

	During the quarter ended September 30, 2014, we recorded two changes in estimates which had the net effect of increasing revenues $26 million. We recorded $94 million, or $0.13 per diluted share, of Medicare revenues as the estimated settlement amount for certain claims denied by Recovery Audit Contractors (“RAC”) entities conducting reviews on behalf of the Centers for Medicare and Medicaid Services (“CMS”) and currently in the pending appeals process. CMS is offering an administrative agreement to providers willing to withdraw their pending appeals in exchange for a timely partial payment (generally, 68% of the claim amount, subject to certain adjustments). We also recorded a reduction of $68 million, or $0.09 per diluted share, to Medicaid revenues related to the Texas Medicaid Waiver Program. On October 1, 2014, the Texas Health and Human Services Commission (“THHSC”) issued a notice to hospitals participating in the Texas Medicaid Waiver Program. According to the notice, a review conducted by CMS identified certain local government/hospital affiliations it believes may be inconsistent with the waiver. As a result of these findings, CMS notified THHSC that it is deferring the federal portion of the Medicaid payments associated with these affiliations while it completes its review.
Recent Pronouncements	'
	Recent Pronouncements
	In May 2014, the Financial Accounting Standards Board and the International Accounting Standards Board issued a final, converged, principles-based standard on revenue recognition. Companies across all industries will use a five-step model to recognize revenue from customer contracts. The new standard, which replaces nearly all existing United States Generally Accepted Accounting Principles (“US GAAP”) and International Financial Reporting Standards revenue recognition guidance, will require significant management judgment in addition to changing the way many companies recognize revenue in their financial statements. The standard is effective for public entities for annual and interim periods beginning after December 15, 2016. Early adoption is not permitted under US GAAP. We are evaluating the effects the adoption of this standard will have on our financial statements and financial disclosures.
Earning Per Share	'
Earning Per Share	We compute basic earnings per share using the weighted average number of common shares outstanding. We compute diluted earnings per share using the weighted average number of common shares outstanding, plus the dilutive effect of outstanding stock options, stock appreciation rights and restricted share units, computed using the treasury stock method.
Interest Rate Swap Agreements	'
	Interest Rate Swap Agreements
	We have entered into interest rate swap agreements to manage our exposure to fluctuations in interest rates. These swap agreements involve the exchange of fixed and variable rate interest payments between two parties based on common notional principal amounts and maturity dates. Pay-fixed interest rate swaps effectively convert LIBOR indexed variable rate obligations to fixed interest rate obligations. The interest payments under these agreements are settled on a net basis. The net interest payments, based on the notional amounts in these agreements, generally match the timing of the related liabilities for the interest rate swap agreements which have been designated as cash flow hedges. The notional amounts of the swap agreements represent amounts used to calculate the exchange of cash flows and are not our assets or liabilities. Our credit risk related to these agreements is considered low because the swap agreements are with creditworthy financial institutions.
Fair Value Measurements and Disclosures	'
	Accounting Standards Codification 820, Fair Value Measurements and Disclosures (“ASC 820”) emphasizes fair value is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement should be determined based on the assumptions market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, ASC 820 establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy).
	Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input significant to the fair value measurement in its entirety. Our assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.
Cash Traded Investments	'
	Cash Traded Investments
	Our cash traded investments are generally classified within Level 1 or Level 2 of the fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. Certain types of cash traded instruments are classified within Level 3 of the fair value hierarchy because they trade infrequently and therefore have little or no price transparency. The valuation of these securities involves management’s judgment, after consideration of market factors and the absence of market transparency, market liquidity and observable inputs. Our valuation models derived fair market values compared to tax-equivalent yields of other securities of similar credit worthiness and similar effective maturities.
Derivative Financial Instruments	'
	Derivative Financial Instruments
	We have entered into interest rate swap agreements to manage our exposure to fluctuations in interest rates. The valuation of these instruments is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. We incorporate credit valuation adjustments to reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements.
	Although we determined the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with our derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by us and our counterparties. We assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions, and at September 30, 2014 and December 31, 2013, we determined the credit valuation adjustments were not significant to the overall valuation of our derivatives.
