Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements are unaudited and, in our opinion, contain all normal recurring adjustments necessary for a fair statement of the results for the periods presented. Our operations are seasonal and results for interim periods are not necessarily indicative of the results for the entire fiscal year. Historically, demand for cruises has been strongest during the Northern Hemisphere’s summer months. The interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2015, which are included in our most recently filed Annual Report on Form 10-K. Reclassification Certain amounts in prior periods have been reclassified to conform to the current period presentation. Revenue and Expense Recognition Deposits received from guests for future voyages are recorded as advance ticket sales and are subsequently recognized as passenger ticket revenue along with onboard and other revenue, and all associated direct costs of a voyage are recognized as cruise operating expenses on a pro-rata basis over the period of the voyage. Guest cancellation fees are recognized in passenger ticket revenue in the month of the cancellation. Certain of our product offerings are accounted for under the guidance included within multi-element arrangements and result in an allocation of the fair value between passenger ticket revenue and onboard and other revenue. Revenue and expenses include port fees and taxes. The amounts included on a gross basis are $80.3 million and $70.1 million for the three months ended September 30, 2016 and 2015, respectively, and $214.3 million and $184.4 million for the nine months ended September 30, 2016 and 2015, respectively. Foreign Currency The majority of our transactions are settled in U.S. dollars. We translate assets and liabilities of our foreign subsidiaries at exchange rates in effect at the balance sheet date. Gains or losses resulting from transactions denominated in other currencies are recognized in our consolidated statements of operations within other expense. We recognized losses of $1.5 million and gains of $3.1 million for the three months ended September 30, 2016 and 2015, respectively, and losses of $1.9 million and gains of $8.8 million for the nine months ended September 30, 2016 and 2015, respectively. Depreciation and Amortization Expense The amortization of deferred financing fees is included in depreciation and amortization expense in the consolidated statements of cash flows; however, for purposes of the consolidated statements of operations it is included in interest expense, net. Goodwill We evaluate goodwill for impairment annually or more frequently when an event occurs or circumstances change that indicates the carrying value of a reporting unit may not be recoverable. Based on the recent performance of the Oceania Cruises’ reporting unit, we performed an interim Step 1 Test which consists of a combined approach using the expected future cash flows and market multiples to determine the fair value of the reporting unit. We determined that there was no impairment of goodwill as the Step 1 Test supports the carrying value of the reporting unit. Recently Issued Accounting Pronouncements In August 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-15 which amends Topic 230 (Statement of Cash Flows) to eliminate discrepancies in reporting certain items in the statement of cash flows. The guidance is effective for annual periods beginning after December 15, 2017 and interim periods within those annual periods with early adoption permitted. The transition should be made using a retrospective approach. We do not believe that the adoption of this guidance will be material to our consolidated statements of cash flows. In May 2016, the FASB issued ASU No. 2016-12 which addresses improvements to the guidance on revenue from contracts from customers regarding collectibility, noncash consideration, and completed contracts at transition. Additionally, it provides a practical expedient for contract modifications at transition and an accounting policy election related to the presentation of sales taxes and other similar taxes collected from customers. The effective date of this guidance is upon adoption of ASU No. 2014-09 which is presented below. We are currently evaluating the impact of the adoption of this guidance to our consolidated financial statements. In May 2016, the FASB issued ASU No. 2016-11 which is a rescission of Securities and Exchange Commission guidance related to the issuance of ASU No. 2014-09 which is presented below. The effective date of this guidance is upon adoption of ASU No. 2014-09. We are currently evaluating the impact of the adoption of this guidance to our consolidated financial statements. In April 2016, the FASB issued ASU No. 2016-10 which does not change the core principle of the guidance in ASU No. 2014-09 but clarifies two aspects: identifying performance obligations and the licensing implementation guidance, while retaining the related principles for those areas. The effective date of this guidance is upon adoption of ASU No. 2014-09. We are currently evaluating the impact of the adoption of this guidance to our consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09 to improve multiple aspects of the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. The guidance is effective for annual periods beginning after December 15, 2016 and interim periods within those annual periods with early adoption permitted. We do not believe that the adoption of this guidance will be material to our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02 which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). The ASU requires lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of more than 12 months. The ASU further modifies lessors’ classification criteria for leases and the accounting for sales-type and direct financing leases. The ASU will also require qualitative and quantitative disclosures designed to give financial statement users additional information on the amount, timing, and uncertainty of cash flows arising from leases. The ASU is effective for annual reporting periods, and interim periods within those annual periods, beginning after December 15, 2018 with early adoption permitted. The ASU is to be applied using a modified retrospective approach. We are currently evaluating the impact of the adoption of this guidance to our consolidated financial statements. In July 2015, the FASB issued ASU No. 2015-11 to simplify the measurement of inventory for all entities. This applies to all inventory that is measured using either the first-in, first-out or average cost method. The guidance requires an entity to measure inventory at the lower of cost and net realizable value. The guidance must be applied prospectively and will be effective for our interim and annual reporting periods beginning after December 15, 2016. Early adoption is permitted as of the beginning of an interim or annual reporting period. We are currently evaluating the impact of the adoption of this guidance to our consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-05 to clarify a customer’s accounting for fees paid in a cloud computing arrangement. The amendments provide guidance to customers about whether a cloud computing arrangement includes a software license or if the arrangement should be accounted for as a service contract. This guidance will impact the accounting of software licenses but will not change a customer’s accounting for service contracts. The guidance will be effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2015. We have adopted this guidance and there has not been an impact to our consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09 which requires entities to recognize revenue through the application of a five-step model, including identification of the contract, identification of the performance obligations, determination of the transaction price, allocation of the transaction price to the performance obligation and recognition of revenue as the entity satisfies the performance obligations. Entities have the option of using either a full retrospective or a modified approach to adopt the guidance. In August 2015, the FASB issued ASU No. 2015-14 deferring the effective date for one year. We can elect to adopt the provisions of ASU No. 2014-09 for annual periods beginning after December 15, 2017 including interim periods within that reporting period or we can elect to early adopt the guidance as of the original effective date. We have initiated an assessment of our systems, data and processes related to the implementation of this guidance. This assessment is expected to be completed during 2017. Additionally, we are currently evaluating the potential impact on our consolidated financial statements.

Long-term Debt, Unclassified [Abstract]
Long-Term Debt	6. Long-Term Debt In June 2016, NCLC and Voyager Vessel Company, LLC, indirect subsidiaries of NCLH, entered into a Second Amended and Restated Credit Agreement (the “Amended Senior Secured Credit Facility”) with a syndicate of banks which restates the Amended and Restated Credit Agreement, dated as of October 31, 2014 (the “Existing Senior Secured Credit Facility”). The Amended Senior Secured Credit Facility amends the Existing Senior Secured Credit Facility to, among other things, (i) (a) increase the aggregate amount of commitments under the Revolving Loan Facility from $625.0 million to $750.0 million (the “New Revolving Loan Facility”) and (b) increase the aggregate principal amount outstanding under the $1.38 billion term loan facility from $1.16 billion to $1.51 billion (the “New Term Loan A Facility”) and (ii) extend the maturity of the New Term Loan A Facility and the New Revolving Loan Facility to June 2021 (the “Extended Maturity Date”). The agreement incorporates a springing maturity date for the New Term Loan A Facility and the New Revolving Loan Facility such that both mature on (A) the earlier date that is 91 days prior to the final maturity date of NCLC’s $680.0 million aggregate principal amount of 5.25% senior unsecured notes due 2019 (the “5.25% Notes”) if on such date (x) the 5.25% Notes have not been repaid (or refinanced with indebtedness maturing after the Extended Maturity Date) by such date and (y) free liquidity does not exceed the aggregate principal amount of outstanding 5.25% Notes by at least $50.0 million and (B) the earlier date that is 91 days prior to the final maturity date of NCLC’s $600.0 million aggregate principal amount of 4.625% senior unsecured notes due 2020 (the “4.625% Notes”) if on such date (x) the 4.625% Notes have not been repaid (or refinanced with indebtedness maturing after the Extended Maturity Date) by such date and (y) free liquidity does not exceed the aggregate principal amount of outstanding 4.625% Notes by at least $50.0 million. NCLC used proceeds of approximately $1.59 billion from the New Term Loan A Facility and the New Revolving Loan Facility to prepay the entire outstanding principal amount of the Revolving Loan Facility, the $1.38 billion term loan facility and a $350.0 million term loan facility. The New Term Loan A Facility and New Revolving Loan Facility bear interest at a rate per annum of (a) an adjusted LIBOR rate or (b) a base rate determined by reference to the greatest of (i) the federal funds rate plus 0.50%, (ii) the prime rate in effect on such day and (iii) the adjusted LIBOR rate plus 1%, in each case plus an applicable margin that is determined by reference to a total leverage ratio, with an applicable margin of between 2.25% and 1.50% with respect to Eurocurrency loans and between 1.25% and 0.50% with respect to base rate loans. The initial applicable margin for borrowings is 2.25% with respect to Eurocurrency borrowings and 1.25% with respect to base rate borrowings. The New Term Loan A Facility is required to be repaid in quarterly installments that commenced in September 2016, in a principal amount equal to (a) in the case of installments payable on or prior to June 6, 2018, 1.25% of the loans outstanding immediately after the closing date under the New Term Loan A Facility and (b) in the case of installments payable after June 6, 2018, 2.50% of the loans outstanding immediately after the closing date under the New Term Loan A Facility, with the remaining unpaid principal amount of loans under the New Term Loan A Facility due and payable in full at maturity on June 6, 2021. Principal amounts outstanding under the New Revolving Loan Facility are due and payable in full at maturity on June 6, 2021, subject to earlier repayment pursuant to the springing maturity date described above. In addition to paying interest on outstanding principal under the borrowings, we are obligated to pay a quarterly commitment fee at a rate determined by reference to a total leverage ratio, with a maximum commitment fee of 40% of the applicable margin for Eurocurrency loans. In June 2016, we took delivery of Seven Seas Explorer. To finance the payment due upon delivery, we had export financing in place for 80% of the contract price. The associated $373.6 million term loan bears interest at 3.43% with a maturity date of June 30, 2028. Principal and interest payments are payable semiannually. NCLC, a subsidiary of NCLH, entered into a Supplemental Agreement, dated July 26, 2016, by and among NCLC, as guarantor, Breakaway Four, Ltd. (the “Borrower”), as borrower, NCL International Ltd., as shareholder, and KfW IPEX-Bank GmbH (“KfW”), as facility agent and lender (the “Credit Agreement Amendment”), which amends the Credit Agreement, dated as of October 12, 2012, by and among NCLC, as parent, the Borrower and KfW, as facility agent and lender (the “Existing Credit Agreement”). The Credit Agreement Amendment amends the Existing Credit Agreement to, among other things, increase the aggregate principal amount of commitments under the multi-draw term loan credit facility from €590.5 million to €729.9 million. Except as provided in the Credit Agreement Amendment, all other provisions of the Existing Credit Agreement remain in full force.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Fair Value Measurements and Derivatives	7. Fair Value Measurements and Derivatives Fair value is defined as the price at which an orderly transaction to sell an asset or to transfer a liability would take place between market participants at the measurement date under current market conditions (that is, an exit price at the measurement date from the perspective of a market participant that holds the asset or owes the liability). Fair Value Hierarchy The following hierarchy for inputs used in measuring fair value should maximize the use of observable inputs and minimize the use of unobservable inputs by requiring that the most observable inputs be used when available: Level 1 Quoted prices in active markets for identical assets or liabilities that are accessible at the measurement dates. Level 2 Significant other observable inputs that are used by market participants in pricing the asset or liability based on market data obtained from independent sources. Level 3 Significant unobservable inputs we believe market participants would use in pricing the asset or liability based on the best information available. Derivatives We are exposed to market risk attributable to changes in interest rates, foreign currency exchange rates and fuel prices. We attempt to minimize these risks through a combination of our normal operating and financing activities and through the use of derivatives. We assess whether derivatives used in hedging transactions are “highly effective” in offsetting changes in the cash flow of our hedged forecasted transactions. We use regression analysis for this hedge relationship and high effectiveness is achieved when a statistically valid relationship reflects a high degree of offset and correlation between the fair values of the derivative and the hedged forecasted transaction. Cash flows from the derivatives are classified in the same category as the cash flows from the underlying hedged transaction. The determination of ineffectiveness is based on the amount of dollar offset between the cumulative change in fair value of the derivative and the cumulative change in fair value of the hedged transaction at the end of the reporting period. If it is determined that a derivative is not highly effective as a hedge, or if the hedged forecasted transaction is no longer probable of occurring, then the amount recognized in accumulated other comprehensive income (loss) is released to earnings. In addition, the ineffective portion of our highly effective hedges is recognized in earnings immediately and reported in other income (expense) in our consolidated statements of operations. There are no amounts excluded from the assessment of hedge effectiveness and there are no credit-risk-related contingent features in our derivative agreements. We monitor concentrations of credit risk associated with financial and other institutions with which we conduct significant business. Credit risk, including but not limited to counterparty non-performance under derivatives and our New Revolving Loan Facility, is not considered significant, as we primarily conduct business with large, well-established financial institutions that we have established relationships with and that have credit risks acceptable to us or the credit risk is spread out among a large number of creditors. We do not anticipate non-performance by any of our significant counterparties. The following table sets forth our derivatives measured at fair value and discloses the balance sheet location (in thousands): Asset Liability Balance Sheet location September 30, 2016 December 31, 2015 September 30, 2016 December 31, 2015 Fuel swaps designated as hedging instruments Prepaid expenses and other assets $ 13,740 $ — $ — $ — Other long-term assets 3,462 — 145 — Accrued expenses and other liabilities — — 73,923 128,740 Other long-term liabilities 7,167 — 65,529 132,494 Foreign currency forward contracts designated as hedging instruments Prepaid expenses and other assets 10,153 — 1,381 — Other long-term assets 14,980 3,446 2,363 1,370 Accrued expenses and other liabilities 1,065 — 8,930 8,737 Other long-term liabilities 1,567 551 4,943 24,181 Foreign currency collar not designated as a hedging instrument Accrued expenses and other liabilities — — — 42,993 Interest rate swaps designated as hedging instruments Accrued expenses and other liabilities — — 3,858 4,079 Other long-term liabilities — — 2,594 3,395 The fair values of swap and forward contracts are determined based on inputs that are readily available in public markets or can be derived from information available in publicly quoted markets. The Company determines the value of options and collars utilizing an option pricing model based on inputs that are either readily available in public markets or can be derived from information available in publicly quoted markets. The option pricing model used by the Company is an industry standard model for valuing options and is used by the broker/dealer community. The inputs to this option pricing model are the option strike price, underlying price, risk-free rate of interest, time to expiration, and volatility. The fair value of option contracts considers both the intrinsic value and any remaining time value associated with those derivatives that have not yet settled. The Company also considers counterparty credit risk and its own credit risk in its determination of all estimated fair values. Our derivatives and financial instruments were categorized as Level 2 in the fair value hierarchy, and we had no derivatives or financial instruments categorized as Level 1 or Level 3. Our derivative contracts include rights of offset with our counterparties. We have elected to net certain assets and liabilities within counterparties when the rights of offset exist. We are not required to post cash collateral related to our derivative instruments.

These options were used to mitigate the financial impact of volatility in foreign currency exchange rates related to our ship construction contracts denominated in euros. If the spot rate at the date the ships were delivered was less than the strike price under these option contracts, we would have paid the deferred premium and would not exercise the foreign currency options.

The notional amount of our foreign currency forward contracts was €2.3 billion, or $2.6 billion based on the euro/U.S. dollar exchange rate as of September 30, 2016.

The notional amount of outstanding debt associated with the interest rate swap agreements was $339.8 million as of September 30, 2016. The effects on the consolidated financial statements of the interest rate swaps which were designated as cash flow hedges were as follows (in thousands): Three Months Ended Nine Months Ended 2016 2015 2016 2015 Gain (loss) recognized in other comprehensive income (loss) – effective portion $ 818 $ (2,652 ) $ (2,638 ) $ (6,811 ) Gain (loss) recognized in other expense – ineffective portion — (9 ) 3 (21 ) Amount reclassified from accumulated other comprehensive income (loss) into interest expense, net 996 1,287 2,977 3,305 We had an interest rate swap that matured which was used to mitigate our exposure to interest rate movements and to manage our interest expense.

The difference between the fair value and carrying value of our long-term debt is due to our fixed and variable rate debt obligations carrying interest rates that are above or below market rates at the measurement dates. The fair value of our long-term debt was calculated based on estimated rates for the same or similar instruments with similar terms and remaining maturities resulting in Level 2 inputs in the fair value hierarchy. Market risk associated with our long-term variable rate debt is the potential increase in interest expense from an increase in interest rates. The calculation of the fair value of our long-term debt is considered a Level 2 input. Other The carrying amounts reported in the consolidated balance sheets of all other financial assets and liabilities approximate fair value.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	9. Commitments and Contingencies Ship Construction Contracts We have Norwegian Joy, Norwegian Bliss and one additional Breakaway Plus Class Ship on order with Meyer Werft shipyard for delivery in the spring of 2017, spring of 2018 and the fall of 2019, respectively. These ships will be amongst the largest in our fleet, reaching approximately 164,600 Gross Tons. The combined contract price of these three ships is approximately €2.6 billion, or $2.9 billion based on the euro/U.S. dollar exchange rate as of September 30, 2016. We have export credit financing in place that provides financing for 80% of their contract prices. We have an Explorer Class Ship on order with Fincantieri shipyard with an original contract price of approximately €422.0 million, or approximately $474.1 million based on the euro/U.S. dollar exchange rate as of September 30, 2016. We have export credit financing in place that provides financing for 80% of the contract price. The Explorer Class Ship is expected to be delivered in the winter of 2020. In connection with the contracts to build these ships, we do not anticipate any contractual breaches or cancellations to occur. However, if any would occur, it could result in, among other things, the forfeiture of prior deposits or payments made by us, subject to certain refund guarantees, and potential claims and impairment losses which may materially impact our business, financial condition and results of operations. Litigation In the normal course of our business, various claims and lawsuits have been filed or are pending against us. Most of these claims and lawsuits are covered by insurance and, accordingly, the maximum amount of our liability is typically limited to our deductible amount. Nonetheless, the ultimate outcome of these claims and lawsuits that are not covered by insurance cannot be determined at this time. We have evaluated our overall exposure with respect to all of our threatened and pending litigation and, to the extent required, we have accrued amounts for all estimable probable losses associated with our deemed exposure. We are currently unable to estimate any other potential contingent losses beyond those accrued, as discovery is not complete nor is adequate information available to estimate such range of loss or potential recovery. However, based on our current knowledge, we do not believe that the aggregate amount or range of reasonably possible losses with respect to these matters will be material to our consolidated results of operations, financial condition or cash flows. We intend to vigorously defend our legal position on all claims and, to the extent necessary, seek recovery.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements are unaudited and, in our opinion, contain all normal recurring adjustments necessary for a fair statement of the results for the periods presented. Our operations are seasonal and results for interim periods are not necessarily indicative of the results for the entire fiscal year. Historically, demand for cruises has been strongest during the Northern Hemisphere’s summer months. The interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2015, which are included in our most recently filed Annual Report on Form 10-K.
Reclassification	Reclassification Certain amounts in prior periods have been reclassified to conform to the current period presentation.
Revenue and Expense Recognition	Revenue and Expense Recognition Deposits received from guests for future voyages are recorded as advance ticket sales and are subsequently recognized as passenger ticket revenue along with onboard and other revenue, and all associated direct costs of a voyage are recognized as cruise operating expenses on a pro-rata basis over the period of the voyage. Guest cancellation fees are recognized in passenger ticket revenue in the month of the cancellation. Certain of our product offerings are accounted for under the guidance included within multi-element arrangements and result in an allocation of the fair value between passenger ticket revenue and onboard and other revenue. Revenue and expenses include port fees and taxes. The amounts included on a gross basis are $80.3 million and $70.1 million for the three months ended September 30, 2016 and 2015, respectively, and $214.3 million and $184.4 million for the nine months ended September 30, 2016 and 2015, respectively.
Foreign Currency	Foreign Currency The majority of our transactions are settled in U.S. dollars. We translate assets and liabilities of our foreign subsidiaries at exchange rates in effect at the balance sheet date. Gains or losses resulting from transactions denominated in other currencies are recognized in our consolidated statements of operations within other expense. We recognized losses of $1.5 million and gains of $3.1 million for the three months ended September 30, 2016 and 2015, respectively, and losses of $1.9 million and gains of $8.8 million for the nine months ended September 30, 2016 and 2015, respectively.
Depreciation and amortization expense	Depreciation and Amortization Expense The amortization of deferred financing fees is included in depreciation and amortization expense in the consolidated statements of cash flows; however, for purposes of the consolidated statements of operations it is included in interest expense, net.
Goodwill	Goodwill We evaluate goodwill for impairment annually or more frequently when an event occurs or circumstances change that indicates the carrying value of a reporting unit may not be recoverable. Based on the recent performance of the Oceania Cruises’ reporting unit, we performed an interim Step 1 Test which consists of a combined approach using the expected future cash flows and market multiples to determine the fair value of the reporting unit. We determined that there was no impairment of goodwill as the Step 1 Test supports the carrying value of the reporting unit.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In August 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-15 which amends Topic 230 (Statement of Cash Flows) to eliminate discrepancies in reporting certain items in the statement of cash flows. The guidance is effective for annual periods beginning after December 15, 2017 and interim periods within those annual periods with early adoption permitted. The transition should be made using a retrospective approach. We do not believe that the adoption of this guidance will be material to our consolidated statements of cash flows. In May 2016, the FASB issued ASU No. 2016-12 which addresses improvements to the guidance on revenue from contracts from customers regarding collectibility, noncash consideration, and completed contracts at transition. Additionally, it provides a practical expedient for contract modifications at transition and an accounting policy election related to the presentation of sales taxes and other similar taxes collected from customers. The effective date of this guidance is upon adoption of ASU No. 2014-09 which is presented below. We are currently evaluating the impact of the adoption of this guidance to our consolidated financial statements. In May 2016, the FASB issued ASU No. 2016-11 which is a rescission of Securities and Exchange Commission guidance related to the issuance of ASU No. 2014-09 which is presented below. The effective date of this guidance is upon adoption of ASU No. 2014-09. We are currently evaluating the impact of the adoption of this guidance to our consolidated financial statements. In April 2016, the FASB issued ASU No. 2016-10 which does not change the core principle of the guidance in ASU No. 2014-09 but clarifies two aspects: identifying performance obligations and the licensing implementation guidance, while retaining the related principles for those areas. The effective date of this guidance is upon adoption of ASU No. 2014-09. We are currently evaluating the impact of the adoption of this guidance to our consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09 to improve multiple aspects of the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. The guidance is effective for annual periods beginning after December 15, 2016 and interim periods within those annual periods with early adoption permitted. We do not believe that the adoption of this guidance will be material to our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02 which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). The ASU requires lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of more than 12 months. The ASU further modifies lessors’ classification criteria for leases and the accounting for sales-type and direct financing leases. The ASU will also require qualitative and quantitative disclosures designed to give financial statement users additional information on the amount, timing, and uncertainty of cash flows arising from leases. The ASU is effective for annual reporting periods, and interim periods within those annual periods, beginning after December 15, 2018 with early adoption permitted. The ASU is to be applied using a modified retrospective approach. We are currently evaluating the impact of the adoption of this guidance to our consolidated financial statements. In July 2015, the FASB issued ASU No. 2015-11 to simplify the measurement of inventory for all entities. This applies to all inventory that is measured using either the first-in, first-out or average cost method. The guidance requires an entity to measure inventory at the lower of cost and net realizable value. The guidance must be applied prospectively and will be effective for our interim and annual reporting periods beginning after December 15, 2016. Early adoption is permitted as of the beginning of an interim or annual reporting period. We are currently evaluating the impact of the adoption of this guidance to our consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-05 to clarify a customer’s accounting for fees paid in a cloud computing arrangement. The amendments provide guidance to customers about whether a cloud computing arrangement includes a software license or if the arrangement should be accounted for as a service contract. This guidance will impact the accounting of software licenses but will not change a customer’s accounting for service contracts. The guidance will be effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2015. We have adopted this guidance and there has not been an impact to our consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09 which requires entities to recognize revenue through the application of a five-step model, including identification of the contract, identification of the performance obligations, determination of the transaction price, allocation of the transaction price to the performance obligation and recognition of revenue as the entity satisfies the performance obligations. Entities have the option of using either a full retrospective or a modified approach to adopt the guidance. In August 2015, the FASB issued ASU No. 2015-14 deferring the effective date for one year. We can elect to adopt the provisions of ASU No. 2014-09 for annual periods beginning after December 15, 2017 including interim periods within that reporting period or we can elect to early adopt the guidance as of the original effective date. We have initiated an assessment of our systems, data and processes related to the implementation of this guidance. This assessment is expected to be completed during 2017. Additionally, we are currently evaluating the potential impact on our consolidated financial statements.
