Accounting Policies [Abstract]

Basis of Presentation

1.	Basis of Presentation

The accompanying unaudited, condensed consolidated financial statements include the accounts of NVR, Inc. (“NVR” or the “Company”) and its subsidiaries and certain other entities in which the Company is deemed to be the primary beneficiary (see Notes 2 and 3 to the accompanying condensed consolidated financial statements). Intercompany accounts and transactions have been eliminated in consolidation. The statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. Because the accompanying condensed consolidated financial statements do not include all of the information and footnotes required by GAAP, they should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. In the opinion of management, all adjustments (consisting only of normal recurring accruals except as otherwise noted herein) considered necessary for a fair presentation have been included. Operating results for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Certain prior year amounts in the condensed consolidated financial statements have been reclassified to conform to 2015 presentation. Reclassifications did not impact net income, total assets or total liabilities, or statement of cash flow classifications.

For the three months ended March 31, 2015 and 2014, comprehensive income equaled net income; therefore, a separate statement of comprehensive income is not included in the accompanying condensed consolidated financial statements.

Variable Interest Entities

Equity Method Investments And Joint Ventures [Abstract]

Variable Interest Entities

2.	Variable Interest Entities

Fixed Price Purchase Agreements

NVR generally does not engage in the land development business. Instead, the Company typically acquires finished building lots at market prices from various development entities under fixed price purchase agreements. The purchase agreements require deposits that may be forfeited if NVR fails to perform under the agreements. The deposits required under the purchase agreements are in the form of cash or letters of credit in varying amounts, and typically range up to 10% of the aggregate purchase price of the finished lots.

NVR believes this lot acquisition strategy reduces the financial requirements and risks associated with direct land ownership and land development. NVR may, at its option, choose for any reason and at any time not to perform under these purchase agreements by delivering notice of its intent not to acquire the finished lots under contract. NVR’s sole legal obligation and economic loss for failure to perform under these purchase agreements is limited to the amount of the deposit pursuant to the liquidated damage provisions contained within the purchase agreements. In other words, if NVR does not perform under a purchase agreement, NVR loses only its deposit. None of the creditors of any of the development entities with which NVR enters fixed price purchase agreements have recourse to the general credit of NVR. NVR generally does not have any specific performance obligations to purchase a certain number or any of the lots, nor does NVR guarantee completion of the development by the developer or guarantee any of the developers’ financial or other liabilities.

NVR is not involved in the design or creation of any of the development entities from which the Company purchases lots under fixed price purchase agreements. The developer’s equity holders have the power to direct 100% of the operating activities of the development entity. NVR has no voting rights in any of the development entities. The sole purpose of the development entity’s activities is to generate positive cash flow returns for the equity holders. Further, NVR does not share in any of the profit or loss generated by the project’s development. The profits and losses are passed directly to the developer’s equity holders.

The deposit placed by NVR pursuant to the fixed price purchase agreement is deemed to be a variable interest in the respective development entities. Those development entities are deemed to be variable interest entities (“VIE”). Therefore, the development entities with which NVR enters into fixed price purchase agreements, including the joint venture limited liability corporations discussed below, are evaluated for possible consolidation by NVR. An enterprise must consolidate a VIE when that enterprise has a controlling financial interest in the VIE. An enterprise is deemed to have a controlling financial interest if it has i) the power to direct the activities of a VIE that most significantly impact the entity’s economic performance, and ii) the obligation to absorb losses of the VIE that could be significant to the VIE or the rights to receive benefits from the VIE that could be significant to the VIE.

NVR believes the activities that most significantly impact a development entity’s economic performance are the operating activities of the entity. Unless and until a development entity completes finished building lots through the development process to be able to sell, the process of which the development entities’ equity investors bear the full risk, the entity does not earn any revenues. The operating development activities are managed solely by the development entity’s equity investors.

The development entities with which NVR contracts to buy finished lots typically select the respective projects, obtain the necessary zoning approvals, obtain the financing required with no support or guarantees from NVR, select who will purchase the finished lots and at what price, and manage the completion of the infrastructure improvements, all for the purpose of generating a cash flow return to the development entity’s equity holders and all independent of NVR. The Company possesses no more than limited protective legal rights through the purchase agreement in the specific finished lots that it is purchasing, and NVR possesses no participative rights in the development entities. Accordingly, NVR does not have the power to direct the activities of a developer that most significantly impact the developer’s economic performance. For this reason, NVR has concluded that it is not the primary beneficiary of the development entities with which the Company enters into fixed price purchase agreements, and therefore, NVR does not consolidate any of these VIEs.

As of March 31, 2015, NVR controlled approximately 63,900 lots through fixed price purchase agreements with deposits in cash and letters of credit totaling $347,000 and $2,400, respectively. As noted above, NVR’s sole legal obligation and economic loss for failure to perform under these purchase agreements is limited to the amount of the deposit pursuant to the liquidated damage provisions contained in the purchase agreements and, in very limited circumstances, specific performance obligations. In addition, NVR has certain properties under contract with land owners that are expected to yield approximately 5,000 lots, which are not included in the number of total lots controlled. Some of these properties may require rezoning or other approvals to achieve the expected yield. These properties are controlled with deposits and letters of credit totaling approximately $3,200 and $2,500, respectively as of March 31, 2015, of which approximately $3,100 is refundable if NVR does not perform under the contract. NVR generally expects to assign the raw land contracts to a land developer and simultaneously enter into a lot purchase agreement with the assignee if the project is determined to be feasible.

NVR’s total risk of loss related to contract land deposits as of March 31, 2015 and December 31, 2014, was as follows:

	March 31, 2015			December 31, 2014
Contract land deposits	$	350,261		$	350,750
Loss reserve on contract land deposits		(55,140	)		(56,074	)
Contract land deposits, net		295,121			294,676
Contingent obligations in the form of letters of credit		4,938			4,674
Contingent specific performance obligations (1)		1,505			1,505
Total risk of loss	$	301,564		$	300,855

(1)	As of both March 31, 2015 and December 31, 2014, the Company was committed to purchase 10 finished lots under specific performance obligations.

Joint Ventures

3.	Joint Ventures

On a limited basis, NVR also obtains finished lots using joint venture limited liability corporations (“JVs”). The JVs are typically structured such that NVR is a non-controlling member and is at risk only for the amount the Company has invested, or has committed to invest, in addition to any deposits placed under fixed price purchase agreements with the joint venture. NVR is not a borrower, guarantor or obligor on any debt of the JVs. The Company enters into standard fixed price purchase agreements to purchase lots from these JVs, and as a result has a variable interest in these JVs.

At March 31, 2015, the Company had an aggregate investment totaling approximately $74,400 in five JVs that are expected to produce approximately 8,600 finished lots, of which approximately 3,300 were not under contract with NVR. In addition, NVR had additional funding commitments in the aggregate totaling approximately $12,500 to three of the JVs at March 31, 2015. The Company has determined that it is not the primary beneficiary of four of the JVs because either NVR and the other JV partner share power or the other JV partner has the controlling financial interest. The aggregate investment in unconsolidated JVs was approximately $72,400 and $80,100 at March 31, 2015 and December 31, 2014, respectively, and is reported in the “Other assets” line item on the accompanying condensed consolidated balance sheets. For the remaining JV, NVR has concluded that it is the primary beneficiary because the Company has the controlling financial interest in the JV. The condensed balance sheets as of March 31, 2015 and December 31, 2014 of the consolidated JV were as follows:

	March 31, 2015		December 31, 2014
Cash	$	1,545	$	481
Restricted cash		—		160
Other assets		266		332
Land under development		1,734		2,617
Total assets	$	3,545	$	3,590
Debt	$	—	$	64
Accrued expenses		1,399		1,231
Equity		2,146		2,295
Total liabilities and equity	$	3,545	$	3,590

Distributions received from the unconsolidated JVs are allocated between return of capital and distributions of earnings based on the ratio of capital contributed by NVR to the total expected returns for the respective JVs, and are classified within the accompanying condensed consolidated statements of cash flows as cash flows from investing activities and operating activities, respectively.

Real Estate [Abstract]

Land Under Development

4.	Land Under Development

On a limited basis, NVR directly acquires raw parcels of land already zoned for its intended use to develop into finished lots. Land under development includes the land acquisition costs, direct improvement costs, capitalized interest where applicable, and real estate taxes. As of March 31, 2015, NVR directly owned four separate raw parcels of land with a carrying value of $35,813 that it intends to develop into approximately 460 finished lots. Of the total finished lots, approximately 90 lots are under contract to be sold to an unrelated party under lot purchase agreements. During the first quarter of 2015, the Company sold five lots to an unrelated party at an aggregate sales price of approximately $1,300. No lots were sold to unrelated parties during the first quarter of 2014. The Company capitalizes interest costs to land under development during the active development of finished lots (see Note 5 for further discussion of capitalized interest). None of the raw parcels had any indicators of impairment as of March 31, 2015. Based on market conditions, NVR may on a limited basis continue to directly acquire additional raw parcels to develop into finished lots.

5.	Capitalized Interest

The Company capitalizes interest costs to land under development during the active development of finished lots. In addition, the Company capitalizes interest costs to its joint venture investments while the investments are considered qualified assets pursuant to ASC 835-20, Interest. Capitalized interest is transferred to sold or unsold inventory as the development of finished lots is completed, then charged to cost of sales upon the Company’s settlement of homes and the respective lots. Interest incurred in excess of the interest capitalizable based on the level of qualified assets is expensed in the period incurred. NVR’s interest costs incurred, capitalized, expensed and charged to cost of sales during the three months ended March 31, 2015 and 2014 was as follows:

Excess Reorganization Value, Goodwill and Other Intangibles

7.	Excess Reorganization Value, Goodwill and Other Intangibles

Reorganization value in excess of identifiable assets (“excess reorganization value”) is an indefinite-lived intangible asset that was created upon NVR’s emergence from bankruptcy on September 30, 1993. Based on the allocation of the reorganization value, the portion of the reorganization value which was not attributed to specific tangible or intangible assets has been reported as excess reorganization value, which is treated similarly to goodwill. Excess reorganization value is not subject to amortization. Rather, excess reorganization value is subject to an impairment assessment on an annual basis or more frequently if changes in events or circumstances indicate that impairment may have occurred. Because excess reorganization value was based on the reorganization value of NVR’s entire enterprise upon emergence from bankruptcy, the impairment assessment is conducted on an enterprise basis based on the comparison of NVR’s total equity to the market value of NVR’s outstanding publicly-traded common stock.

As of March 31, 2015, goodwill and net finite-lived intangible assets totaled $441 and $4,578, respectively. The remaining finite-lived intangible assets are amortized on a straight-line basis over a weighted average life of four years. Accumulated amortization as of March 31, 2015 was $3,110. Amortization expense related to the finite-lived intangible assets was $346 for both the three months ended March 31, 2015 and 2014.

The Company completed the annual impairment assessment of the excess reorganization value and goodwill during the first quarter of 2015 and determined that there was no impairment.

Guarantees [Abstract]

Product Warranties

9.	Product Warranties

The Company establishes warranty and product liability reserves (“warranty reserve”) to provide for estimated future expenses as a result of construction and product defects, product recalls and litigation incidental to NVR’s homebuilding business. Liability estimates are determined based on management’s judgment, considering such factors as historical experience, the likely current cost of corrective action, manufacturers’ and subcontractors’ participation in sharing the cost of corrective action, consultations with third party experts such as engineers, and discussions with the Company’s general counsel and outside counsel retained to handle specific product liability cases. The following table reflects the changes in the Company’s warranty reserve during the three months ended March 31, 2015 and 2014:

	Three Months Ended March 31,
	2015			2014
Warranty reserve, beginning of period	$	94,060		$	101,507
Provision		9,081			10,260
Payments		(13,398	)		(13,002	)
Warranty reserve, end of period	$	89,743		$	98,765

Segment Reporting [Abstract]

Segment Disclosures

10.	Segment Disclosures

The following disclosure includes four homebuilding reportable segments that aggregate geographically the Company’s homebuilding operating segments, and the mortgage banking operations presented as a single reportable segment. The homebuilding reportable segments are comprised of operating divisions in the following geographic areas:

Mid Atlantic:		Maryland, Virginia, West Virginia, Delaware and Washington, D.C.
North East:		New Jersey and Eastern Pennsylvania
Mid East:		New York, Ohio, Western Pennsylvania, Indiana and Illinois
South East:		North Carolina, South Carolina, Florida and Tennessee

Homebuilding profit before tax includes all revenues and income generated from the sale of homes, less the cost of homes sold, selling, general and administrative expenses and a corporate capital allocation charge. The corporate capital allocation charge is eliminated in consolidation and is based on the segment’s average net assets employed. The corporate capital allocation charged to the operating segment allows the Chief Operating Decision Maker (“CODM”) to determine whether the operating segment’s results are providing the desired rate of return after covering the Company’s cost of capital. In addition, certain assets, including goodwill and intangible assets and consolidation adjustments as discussed further below, are not allocated to the operating segments as those assets are neither included in the operating segment’s corporate capital allocation charge, nor in the CODM’s evaluation of the operating segment’s performance. The Company records charges on contract land deposits when it is determined that it is probable that recovery of the deposit is impaired. For segment reporting purposes, impairments on contract land deposits are charged to the operating segment upon the determination to terminate a finished lot purchase agreement with the developer, or to restructure a lot purchase agreement resulting in the forfeiture of the deposit. Mortgage banking profit before tax consists of revenues generated from mortgage financing, title insurance and closing services, less the costs of such services and general and administrative costs. Mortgage banking operations are not charged a corporate capital allocation charge.

In addition to the corporate capital allocation and contract land deposit impairments discussed above, the other reconciling items between segment profit and consolidated profit before tax include unallocated corporate overhead (including all management incentive compensation), equity-based compensation expense, consolidation adjustments and external corporate interest expense. NVR’s overhead functions, such as accounting, treasury and human resources, are centrally performed and the costs are not allocated to the Company’s operating segments. Consolidation adjustments consist of such items necessary to convert the reportable segments’ results, which are predominantly maintained on a cash basis, to a full accrual basis for external financial statement presentation purposes, and are not allocated to the Company’s operating segments. External corporate interest expense primarily consists of interest charges on the Company’s 3.95% Senior Notes due 2022 (the “Senior Notes”) and is not charged to the operating segments because the charges are included in the corporate capital allocation discussed above.

Following are tables presenting segment revenues, profit and assets, with reconciliations to the amounts reported for the consolidated enterprise, where applicable:

Fair Value

3 Months Ended

Mar. 31, 2015

Fair Value Disclosures [Abstract]

Fair Value

11.	Fair Value

Financial Instruments

The estimated fair value of NVR’s Senior Notes as of March 31, 2015 was $630,750. The estimated fair value is based on recent market prices of similar transactions, which is classified as Level 2 within the fair value hierarchy. The carrying value of the Senior Notes was $599,189 at March 31, 2015. Except as otherwise noted below, NVR believes that insignificant differences exist between the carrying value and the fair value of its financial instruments, which consist of cash equivalents, due to their short term nature.

Derivative Instruments and Mortgage Loans Held for Sale

In the normal course of business, NVR’s wholly-owned mortgage subsidiary, NVR Mortgage Finance, Inc. (“NVRM”), enters into contractual commitments to extend credit to buyers of single-family homes with fixed expiration dates. The commitments become effective when the borrowers "lock-in" a specified interest rate within time frames established by NVRM. All mortgagors are evaluated for credit worthiness prior to the extension of the commitment. Market risk arises if interest rates move adversely between the time of the "lock-in" of rates by the borrower and the sale date of the loan to a broker/dealer. To mitigate the effect of the interest rate risk inherent in providing rate lock commitments to borrowers, NVRM enters into optional or mandatory delivery forward sale contracts to sell whole loans and mortgage-backed securities to broker/dealers. The forward sale contracts lock in an interest rate and price for the sale of loans similar to the specific rate lock commitments. NVRM does not engage in speculative or trading derivative activities. Both the rate lock commitments to borrowers and the forward sale contracts to broker/dealers are undesignated derivatives and, accordingly, are marked to fair value through earnings. At March 31, 2015, there were contractual commitments to extend credit to borrowers aggregating $357,473 and open forward delivery contracts aggregating $471,289, which hedge both the rate lock loan commitments and closed loans held for sale.

GAAP assigns a fair value hierarchy to the inputs used to measure fair value. Level 1 inputs are quoted prices in active markets for identical assets and liabilities. Level 2 inputs are inputs other than quoted market prices that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs. The fair value of NVRM’s rate lock commitments to borrowers and the related input levels include, as applicable:

i)	the assumed gain/loss of the expected resultant loan sale (Level 2);

ii)	the effects of interest rate movements between the date of the rate lock and the balance sheet date (Level 2); and

iii)	the value of the servicing rights associated with the loan (Level 2).

The assumed gain/loss considers the excess servicing to be received or buydown fees to be paid upon securitization of the loan. The excess servicing and buydown fees are calculated pursuant to contractual terms with investors. To calculate the effects of interest rate movements, NVRM utilizes applicable published mortgage-backed security prices, and multiplies the price movement between the rate lock date and the balance sheet date by the notional loan commitment amount. NVRM sells all of its loans on a servicing released basis, and receives a servicing released premium upon sale. Thus, the value of the servicing rights, which averaged 109 basis points of the loan amount as of March 31, 2015, is included in the fair value measurement and is based upon contractual terms with investors and varies depending on the loan type. NVRM assumes an approximate 12% fallout rate when measuring the fair value of rate lock commitments. Fallout is defined as locked loan commitments for which NVRM does not close a mortgage loan and is based on historical experience.

The fair value of NVRM’s forward sales contracts to broker/dealers solely considers the market price movement of the same type of security between the trade date and the balance sheet date (Level 2). The market price changes are multiplied by the notional amount of the forward sales contracts to measure the fair value.

Mortgage loans held for sale are recorded at fair value when closed, and thereafter are carried at the lower of cost or fair value, net of deferred origination costs, until sold. Fair value is measured using Level 2 inputs. The fair value of loans held for sale of $154,785 included on the accompanying condensed consolidated balance sheet has been increased by $1,426 from the aggregate principal balance of $153,359.

The undesignated derivative instruments are included on the accompanying condensed consolidated balance sheet, as of March 31, 2015, as follows:

	Fair Value		Balance Sheet Location
Rate lock commitments:
Gross assets	$	5,235
Gross liabilities		1,292
Net rate lock commitments	$	3,943	NVRM - Other assets
Forward sales contracts:
Gross assets	$	176
Gross liabilities		2,143
Net forward sales contracts	$	1,967	NVRM - Accounts payable and other liabilities

The fair value measurement as of March 31, 2015 was as follows:

	Notional or Principal Amount		Assumed Gain/(Loss) From Loan Sale			Interest Rate Movement Effect			Servicing Rights Value		Security Price Change			Total Fair Value Measurement Gain/(Loss)
Rate lock commitments	$	357,473	$	(812	)	$	1,338		$	3,417	$	—		$	3,943
Forward sales contracts	$	471,289		—			—			—		(1,967	)		(1,967	)
Mortgages held for sale	$	153,359		(180	)		(94	)		1,700		—			1,426
Total fair value measurement			$	(992	)	$	1,244		$	5,117	$	(1,967	)	$	3,402

For the three months ended March 31, 2015 and 2014, NVRM recorded a fair value adjustment to expense of $422 and a fair value adjustment to income of $420, respectively. Unrealized gains/losses from the change in the fair value measurements are included in earnings as a component of mortgage banking fees in the accompanying condensed consolidated statements of income. The fair value measurement will be impacted in the future by the change in the value of the servicing rights, interest rate movements, security price fluctuations, and the volume and product mix of NVRM’s closed loans and locked loan commitments.

Commitments And Contingencies Disclosure [Abstract]

Commitments and Contingencies

13.	Commitments and Contingencies

In October 2004, Patrick Tracy, whom NVR had employed as a Sales and Marketing Representative (“SMR”), filed a lawsuit against the Company in the U.S. District Court for the Western District of New York alleging that NVR had misclassified him and other SMRs as outside sales personnel exempt from certain state and federal wage laws, including overtime pay requirements. Mr. Tracy’s attorneys subsequently filed several other lawsuits in various courts asserting substantially similar claims on behalf of various classes or groups of SMRs. None of those courts have held that the claims are appropriate for class, collective, or other group treatment, and the Western District of New York ruled in April 2013 that the claims in Mr. Tracy’s case could not proceed on such a basis. The Western District of New York reached the same conclusion in July 2014 regarding a separate case that Mr. Tracy’s attorneys brought on behalf of other SMRs.

In October 2013, Mr. Tracy’s individual claims were tried by a jury, which returned a unanimous verdict in NVR’s favor and found that the Company had properly classified Mr. Tracy as an exempt outside sales person. The plaintiff has sought review in the U.S. Court of Appeals for the Second Circuit, in which he challenges the legal standard that the trial court applied in crafting its jury instructions regarding the outside sales exemption, in addition to rulings that the trial court made at earlier stages of the case. That appeal is fully briefed and scheduled for oral argument on May 15, 2015. The remainder of the cases noted above are in various stages of pre-trial proceedings, many of them stayed or administratively closed pending a final disposition of the Tracy action.

The Company believes that the compensation practices in regard to SMRs are entirely lawful and has vigorously defended all claims challenging those practices. In light of the points noted above, the Company has not recorded any associated liabilities on the accompanying condensed consolidated balance sheets in conjunction with any of those claims.

In June 2010, the Company received a Request for Information from the United States Environmental Protection Agency (“EPA”) pursuant to Section 308 of the Clean Water Act. The request sought information about storm water discharge practices in connection with homebuilding projects completed or underway by the Company in New York and New Jersey. The Company cooperated with this request, and provided information to the EPA. The Company was subsequently informed by the United States Department of Justice (“DOJ”) that the EPA forwarded the information on the matter to the DOJ, and the DOJ requested that the Company meet with the government to discuss the status of the case. Meetings took place in January 2012, August 2012 and November 2014 with representatives from both the EPA and DOJ. The Company has continued discussions with the EPA and DOJ. It is as yet unclear what next steps the DOJ will take in the matter. The Company intends to continue cooperating with any future EPA and/or DOJ inquiries. At this time, the Company cannot predict the outcome of this inquiry, nor can it reasonably estimate the potential costs that may be associated with its eventual resolution.

The Company and its subsidiaries are also involved in various other litigation arising in the ordinary course of business. In the opinion of management, and based on advice of legal counsel, this litigation is not expected to have a material adverse effect on the financial position, results of operations or cash flows of the Company. Legal costs incurred in connection with outstanding litigation are expensed as incurred.

Accounting Changes And Error Corrections [Abstract]

Recent Accounting Pronouncements

14.	Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The standard will replace most existing revenue recognition guidance in GAAP when it becomes effective. The standard is effective for the Company on January 1, 2017. Early adoption is not permitted. The standard permits the use of either the retrospective or cumulative effect transition method. The Company has not yet selected a transition method and is currently evaluating the effect that the standard will have on its consolidated financial statements and related disclosures.

In August 2014, FASB issued ASU 2014-15, Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. The standard requires an entity’s management to evaluate at each annual and interim reporting period whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date the financial statements are issued and to provide related footnote disclosures. The standard is effective for the first annual period ending after December 15, 2016, and interim periods thereafter. The Company does not believe that the adoption of this standard will have a material effect on its consolidated financial statements and related disclosures.

In February 2015, FASB issued ASU 2015-02, Consolidation (Topic 810) – Amendments to the Consolidation Analysis. The standard changes the manner in which reporting entities evaluate consolidation requirements of certain legal entities. The standard is effective for the annual and interim periods in fiscal years beginning after December 15, 2015. The Company is currently evaluating the effect that the standard will have on its consolidated financial statements and related disclosures.

In April 2015, FASB issued ASU 2015-03, Interest – Imputation of Interest (Subtopic 835-30) – Simplifying the Presentation of Debt Issuance Costs. The standard requires that debt issuance costs related to a recognized debt liability be presented on the balance sheet as a direct deduction from the debt liability, rather than as an asset. The standard is effective for the Company for the first annual period ending after December 15, 2015, and must be applied retrospectively to all prior periods presented in the financial statements. The Company does not believe that the adoption of this standard will have a material effect on its consolidated financial statements and related disclosures.

In April 2015, FASB issued ASU 2015-05, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40). The standard adds guidance to Subtopic 350-40 to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement. The standard provides a basis for evaluating whether a cloud computing arrangement includes a software license or whether the arrangement should be accounted for as a service contract. The standard is effective for the annual and interim periods in fiscal years beginning after December 15, 2015. The Company is currently evaluating the effect that the standard will have on its consolidated financial statements and related disclosures.
