Basis of Presentation	'
	1. Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements of IRIDEX Corporation (“IRIDEX”, the “Company”, “we”, “our”, or “us”) have been prepared in accordance with generally accepted accounting principles in the United States (“US GAAP”) for interim financial information and pursuant to the instructions to Form 10-Q and Article 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by US GAAP for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring adjustments, considered necessary for a fair presentation of the financial statements have been included.
	The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto, together with management’s discussion and analysis of the Company’s financial condition and results of operations, contained in our Annual Report on Form 10-K for the fiscal year ended December 28, 2013, which was filed with the Securities and Exchange Commission (“SEC”) on March 27, 2014. The results of operations for the three and six months ended June 28, 2014 are not necessarily indicative of the results for the year ending December 27, 2014 or any future interim period.

Summary of Significant Accounting Policies	'
	2. Summary of Significant Accounting Policies
	The Company’s significant accounting policies are disclosed in our Annual Report on Form 10-K for the year ended December 28, 2013, which was filed with the SEC on March 27, 2014.
	Financial Statement Presentation.
	The consolidated financial statements include the accounts of the Company and our wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.
	Use of Estimates.
	The preparation of consolidated financial statements in conformity with US GAAP requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, and expenses and the related disclosure of contingent assets and liabilities. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. In addition, any change in these estimates or their related assumptions could have an adverse effect on our operating results.
	Revenue Recognition.
	Our revenues arise from the sale of laser consoles, delivery devices, consumables and service and support activities. Revenue from product sales is recognized upon receipt of a purchase order and product shipment provided that no significant obligations remain and collection of the receivables is reasonably assured. Shipments are generally made with Free-On-Board (“FOB”) shipping point terms, whereby title passes upon shipment from our dock. Any shipments with FOB receiving point terms are recorded as revenue when the shipment arrives at the receiving point. Cost is recognized as product sales revenue is recognized. The Company’s sales may include post-sales obligations for training or other deliverables. For revenue arrangements such as these, we recognize revenue in accordance with ASC 605, Revenue Recognition, Multiple-Element Arrangements. The Company allocates revenue among deliverables in multiple-element arrangements using the relative selling price method. Revenue allocated to each element is recognized when the basic revenue recognition criteria is met for each element. The Company is required to apply a hierarchy to determine the selling price to be used for allocating revenue to deliverables: (i) vendor-specific objective evidence of selling price (“VSOE”), (ii) third-party evidence of selling price (“TPE”) and (iii) best estimate of the selling price (“ESP”). In general, the Company is unable to establish VSOE or TPE for all of the elements in the arrangement; therefore, revenue is allocated to these elements based on the Company’s ESP, which the Company determines after considering multiple factors such as management approved pricing guidelines, geographic differences, market conditions, competitor pricing strategies, internal costs and gross margin objectives. These factors may vary over time depending upon the unique facts and circumstances related to each deliverable. As a result, the Company’s ESP for products and services could change. Revenues for post-sales obligations are recognized as the obligations are fulfilled.
	In international regions, we utilize distributors to market and sell our products. We recognize revenue upon shipment for sales to these independent, third party distributors as we have no continuing obligations subsequent to shipment. Generally our distributors are responsible for all marketing, sales, installation, training and warranty labor coverage for our products. Our standard terms and conditions do not provide price protection or stock retention rights to any of our distributors.
	Royalty revenues are typically based on licensees’ net sales of products that utilize our technology and are recognized as earned in accordance with the contract terms when royalties from licensees can be reliably measured and collectibility is reasonably assured, such as upon the earlier of the receipt of a royalty statement from the licensee or upon payment by the licensee.
	Taxes Collected from Customers and Remitted to Governmental Authorities.
	Taxes collected from customers and remitted to governmental authorities are recognized on a net basis in the accompanying consolidated statements of operations.
	Shipping and Handling Costs.
	Our shipping and handling costs billed to customers are included in revenues and the associated expense is recorded in cost of revenues for all periods presented.
	Deferred Revenue.
	Revenue related to extended service contracts is deferred and recognized on a straight line basis over the period of the applicable service contract. Costs associated with these service arrangements are recognized as incurred.
	A reconciliation of the changes in the Company’s deferred revenue balance for the six months ended June 28, 2014 and June 29, 2013 is as follows:
		Six Months Ended
	(in thousands)	June 28,			June 29,
		2014			2013
	Balance, beginning of period	$	1,133		$	1,004
	Additions to deferral		636			646
	Revenue recognized		(686	)		(632	)
	Balance, end of period	$	1,083		$	1,018
	Warranty.
	The Company generally provides a one to two year warranty on its products, which is accrued for upon shipment of products. Actual warranty costs incurred have not materially differed from those accrued. The Company’s warranty policy is applicable to products which are considered defective in their performance or fail to meet the product specifications. Warranty costs are reflected in the statement of operations as cost of revenues.
	A reconciliation of the changes in the Company’s warranty liability for the six months ended June 28, 2014 and June 29, 2013 is as follows:
		Six Months Ended
	(in thousands)	June 28,			June 29,
		2014			2013
	Balance, beginning of period	$	468		$	453
	Accruals for product warranties		134			114
	Cost of warranty claims and adjustments		(96	)		(110	)
	Balance, end of period	$	506		$	457
	Recently Issued and Adopted Accounting Standards.
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2013-11, “Presentation of an Unrecognized Tax Benefit when a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” This standard requires an entity to present unrecognized tax benefits as a reduction to deferred tax assets when a net operating loss carryforward, similar tax loss or a tax credit carryforward exists, with limited exceptions. This standard is effective for fiscal years beginning on or after December 15, 2013, and for interim periods within those fiscal years. Since ASU 2013-11 only impacts financial statement disclosure requirements for unrealized tax benefits, its adoption did not have an impact on the Company’s financial position or results of operations.
	In May 2014, as part of its ongoing efforts to assist in the convergence of U.S. GAAP and International Financial Reporting Standards (“IFRS”), FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” The new guidance sets forth a new five-step revenue recognition model which replaces the prior revenue recognition guidance in its entirety and is intended to eliminate numerous industry-specific pieces of revenue recognition guidance that have historically existed in U.S. GAAP. The underlying principle of the new standard is that a business or other organization will recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects what it expects in exchange for the goods or services. The standard also requires more detailed disclosures and provides additional guidance for transactions that were not addressed completely in the prior accounting guidance. The ASU provides alternative methods of initial adoption and is effective for annual and interim periods beginning after December 15, 2016. We are currently evaluating the impact that this standard will have on our consolidated financial statements.

	4. Goodwill and Intangible Assets
	Goodwill.
	The carrying value of goodwill was $0.5 million as of June 28, 2014 and December 28, 2013.
	Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination. The Company reviews goodwill for impairment on an annual basis or whenever events or changes in circumstances indicate the carrying value may not be recoverable. The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step quantitative goodwill impairment test. If, after assessing the totality of circumstances, an entity determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then it is required to perform the two-step impairment test. An entity is not required to calculate the fair value of a reporting unit unless the entity determines that it is more likely than not that its fair value is less than its carrying value. However, an entity also has the option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to performing the first step of the two-step goodwill impairment test. The Company has determined that it has a single reporting unit for purposes of performing its goodwill impairment test. As the Company uses the market approach to assess impairment, its common stock price is an important component of the fair value calculation. If the Company’s stock price continues to experience significant price and volume fluctuations, this will impact the fair value of the reporting unit and can lead to potential impairment in future periods. The Company performed its annual impairment test during the second quarter ended June 28, 2014 and determined that its goodwill was not impaired.

Fair_Value_Measurements

Fair Value Measurements	'
	5. Fair Value Measurements
	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (2) an entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below:
	—	Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities.
	—	Level 2: Directly or indirectly observable inputs as of the reporting date through correlation with market data, including quoted prices for similar assets and liabilities in active markets and quoted prices in markets that are not active. Level 2 also includes assets and liabilities that are valued using models or other pricing methodologies that do not require significant judgment since the input assumptions used in the models, such as interest rates and volatility factors, are corroborated by readily observable data from actively quoted markets for substantially the full term of the financial instrument.
	—	Level 3: Unobservable inputs that are supported by little or no market activity and reflect the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions.
	In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible, as well as considers counterparty credit risk in its assessment of fair value.
	The carrying amounts of the Company’s financial assets and liabilities, including cash and cash equivalents, accounts receivable, accounts payable, and accrued expenses as of June 28, 2014 and December 28, 2013, approximate fair value because of the short maturity of these instruments.
	As of June 28, 2014 and December 28, 2013, financial assets and liabilities measured and recognized at fair value on a recurring basis and classified under the appropriate level of the fair value hierarchy as described above were as follows:
		28-Jun-14										December 28, 2013
		Fair Value Measurements										Fair Value Measurements

	Liabilities:
	Earn-out liability		—		—		$	551		$	551	$	—		—	$	624	$	624
	The Company’s Level 1 financial assets are money market funds whose fair values are based on quoted market prices. The Company does not have any Level 2 financial assets or liabilities. The fair value of the earn-out liability arising from the acquisitions of RetinaLabs, Inc. and Ocunetics, Inc. is classified within Level 3 of the fair value hierarchy since it is based on significant unobservable inputs. The significant unobservable inputs include projected royalties and discount rates to present value the payments. A significant increase (decrease) in the projected royalty payments in isolation could result in a significantly higher (lower) fair value measurement and a significant increase (decrease) in the discount rate in isolation could result in a significantly lower (higher) fair value measurement. The fair value of the earn-out liability is calculated on a quarterly basis by the Company based on a collaborative effort of the Company’s operations, finance and accounting groups based on additional information as it becomes available. Any change in the fair value adjustment is recorded in the statement of operations of that period.
	The following table presents quantitative information about the inputs and valuation methodologies used for our fair value measurements classified in Level 3 of the fair value hierarchy as of June 28, 2014.
	As of June 28, 2014			Fair Value	Valuation		Significant		Weighted

	A reconciliation of the changes in the Company’s earn-out liability (Level 3 liability) for the six months ended June 28, 2014 and June 29, 2013 is as follows:

	6. Stock Based Compensation
	2008 Equity Incentive Plan
	For the six months ended June 28, 2014, the only active share-based compensation plan was the 2008 Equity Incentive Plan (the “Incentive Plan”). The terms of awards granted during the six months ended June 28, 2014 were consistent with those described in the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 28, 2013.
	Summary of Stock Options
	The following table summarizes information regarding activity in our stock option plan during the six months ended June 28, 2014:
		Number of			Weighted			Aggregate

	Canceled or forfeited		(25,696	)	$	6.28
	Outstanding as of June 28, 2014		995,036		$	4.50		$	3,821
	The weighted average grant date fair value of the options granted under the Company’s stock plans as calculated using the Black-Scholes option-pricing model was $4.09 and $2.89 per share for the three months ended June 28, 2014 and June 29, 2013, respectively. The weighted-average grant date fair value of the options granted under the Company’s stock plans as calculated using the Black-Scholes option-pricing model was $4.09 and $3.00 per share for the six months ended June 28, 2014 and June 29, 2013, respectively.
	The Company uses the Black-Scholes option-pricing model to estimate fair value of stock-based awards (options) with the following weighted average assumptions:
		Three Months Ended						Six Months Ended
		June 28,			June 29,			June 28,			June 29,
		2014			2013			20143			2013
	Average risk free interest rate		1.45	%		1.31	%		1.48	%		0.83	%
	Expected life (in years)		4.5 years			4.5 years			4.5 years			4.5 years
	Dividend yield		—	%		—	%		—	%		—	%
	Average volatility		55	%		79	%		57	%		84	%
	Option-pricing models require the input of various subjective assumptions, including the option’s expected life and the price volatility of the underlying stock. The expected stock price volatility is based on analysis of the Company’s stock price history over a period commensurate with the expected term of the options, trading volume of the Company’s stock, look-back volatilities and Company specific events that affected volatility in a prior period. The expected term of employee stock options represents the weighted average period the stock options are expected to remain outstanding and is based on the history of exercises and cancellations on all past option grants made by the Company, the contractual term, the vesting period and the expected remaining term of the outstanding options. The risk-free interest rate is based on the U.S. Treasury interest rates whose term is consistent with the expected life of the stock options. No dividend yield is included as the Company has not issued any dividends and does not anticipate issuing any dividends in the future.
	The following table shows stock-based compensation expense included in the condensed consolidated statements of operations for the three and six months ended June 28, 2014 and June 29, 2013:
		Three Months Ended						Six Months Ended
		June 28,			June 29,			June 28,			June 29,

	General and administrative		141			100			297			197
		$	234		$	173		$	478		$	334
	Approximately $15 thousand and $11 thousand of the stock-based compensation recognized was capitalized into inventory as a component of overhead for the quarters ended June 28, 2014 and June 29, 30, 2013, respectively.
	Information regarding stock options outstanding, vested and expected to vest and exercisable as of June 28, 2014 is summarized below:
		Number of			Weighted			Weighted			Aggregate
		Shares			Average			Average			Intrinsic Value
					Exercise Price			Remaining			(thousands)
								Contractual
								Life (Years)
	Options outstanding		995,036		$	4.5			4.03		$	3,821
	Options vested and expected to vest		926,071		$	4.38			3.88		$	3,662
	Options exercisable		564,581		$	3.58			2.69		$	2,655
	The aggregate intrinsic value in the table above represents the pre-tax intrinsic value, based on the Company’s closing price as of June 27, 2014, that would have been received by option holders had all option holders exercised their stock options as of that date. This amount changes based on the fair market value of the Company’s stock. The total intrinsic value of options exercised for the six months ended June 28, 2014 and June 29, 2013 was approximately $566 thousand and $445 thousand, respectively.
	As of June 28, 2014, there was $1.6 million of total unrecognized compensation cost, net of expected forfeitures, related to non-vested share-based compensation arrangements under the Incentive Plan. The cost is expected to be recognized over a weighted average period of 2.79 years.
	Summary of Restricted Stock Units and Awards
	Information regarding the restricted stock units activity for the six months ended June 28, 2014 is summarized below:
		Number
		of Shares
	Outstanding as of December 28, 2013		269,259
	Restricted stock units granted		50,000
	Restricted stock units released		(36,250	)
	Outstanding as of June 28, 2014		283,009
	On January 4, 2014, the Company granted a restricted stock unit award for up to 50,000 shares of the Company’s common stock (the “Market Performance Award”) under the terms of the Company’s 2008 Equity Incentive Plan, as amended, to the Company’s President and Chief Executive Officer. The number of shares issuable pursuant to the Market Performance Award will be based upon the Company’s calculated stock price (average stock price performance during the two months prior to and two months following the date the service condition is met, or the fair market value of the Company’s common stock in the event vesting is triggered by a change of control of the Company). The Market Performance Award is expected to vest on December 31, 2014, given that no other vesting triggers occur prior to that date. To the extent that the market condition is not met, the Market Performance Award will not vest and will be cancelled. None of the restricted stock units will vest if the calculated stock price is less than $11.00 per share. Since the market conditions will affect the vesting of the Market Performance Award, the Company cannot use the Black-Scholes option-pricing model to value the award; instead, a binomial model must be used. The Company utilized the Monte Carlo simulation technique, which incorporated assumptions for the expected holding period, risk-free interest rate, stock price volatility and dividend yield. Compensation expense is recognized ratably until such time as the market condition is satisfied. The grant date fair value for restricted stock units awarded during the six month period was $234 thousand. The weighted average stock price on the date of grant for restricted stock units awarded during the six month period was $4.67 per share.
	There were no restricted stock awards granted, vested and forfeited for the six months ended June 28, 2014.
	Stock Repurchase Program
	In February 2013, the Board of Directors approved a new one year $3.0 million stock repurchase program that replaced the prior two year $4.0 million stock repurchase program. On February 27, 2014, the Board of Directors approved the extension of the plan for an additional year. For the six months ended June 28, 2014, the Company has purchased 260,196 shares at an average price of $8.63 per share. As of June 28, 2014, the Company still has the authorization to purchase up to $328 thousand in common shares under the stock repurchase program.

	7. Income Taxes
	Provision for Income Tax
	The Company calculates its interim tax provision in accordance with the provisions of ASC 740-270, “Income Taxes; Interim Reporting”. For interim periods, the Company estimates its annual effective income tax rate and applies the estimated rate to the year-to-date income or loss before income taxes. The Company also computes the tax provision or benefit related to items reported separately and recognizes the items net of their related tax effect in the interim periods in which they occur. The Company also recognizes the effect of changes in enacted tax laws or rates in the interim periods in which the changes occur. The Company recorded a provision for income taxes of $25 thousand for the six months ended June 28, 2014 and $8 thousand for the six months ended June 29, 2013.
	Deferred Income Taxes
	The Company accounts for income taxes in accordance with ASC topic 740, Income Taxes (“ASC 740”), which requires that deferred tax assets and liabilities be recognized using enacted tax rates for the effect of temporary differences between the book and tax bases of recorded assets and liabilities. ASC 740 also requires that deferred tax assets be reduced by a valuation allowance if it is more likely than not that some or all of the deferred tax assets will not be realized. As of December 28, 2013, the Company had a deferred tax asset of approximately $10.0 million which is fully offset by a valuation allowance. If realized, the asset will be reflected on the Company’s balance sheet and the reversal of the corresponding valuation allowance will result in a tax benefit being recorded in the statement of operations in the respective period. No additional deferred income tax has been recorded during the quarter.
	Uncertain Tax Positions
	The Company accounts for its uncertain tax positions in accordance with ASC 740. As of December 28, 2013, the Company had $1.0 million of unrecognized tax benefits which would impact the income statement if recognized.
	The Company is not aware of any other uncertain tax positions that could result in significant additional payments, accruals, or other material deviation in this estimate during the fiscal year.
	The Company files U.S. federal and state returns, as well as foreign returns in France. The tax years 2008 to 2013 remain open in several jurisdictions, none of which have individual significance.

Computation of Basic and Diluted Net Income Per Common Share	'
	8. Computation of Basic and Diluted Net Income Per Common Share
	Basic net income per share is computed by dividing net income for the period by the weighted average number of shares outstanding during the period.
	Diluted net income per share is computed by dividing net income for the period by the weighted average number of shares, plus the weighted average common stock equivalents outstanding during the period. The Company excludes options from the computation of diluted weighted average shares outstanding if the exercise price of the options is greater than the average market price of the shares because the inclusion of these options would be anti-dilutive to earnings per share. Accordingly, for the three months ended June 28, 2014 and June 29, 2013, respectively, stock options to purchase 123,393 and 539,230 shares were excluded from the computation of diluted weighted average shares outstanding. For the six months ended June 28, 2014 and June 29, 2013, respectively, stock options to purchase 91,448 and 574,656 shares were excluded from the computation of diluted weighted average shares outstanding.

Use of Estimates	'
	Use of Estimates.
	The preparation of consolidated financial statements in conformity with US GAAP requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, and expenses and the related disclosure of contingent assets and liabilities. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. In addition, any change in these estimates or their related assumptions could have an adverse effect on our operating results.
Revenue Recognition	'
	Revenue Recognition.
	Our revenues arise from the sale of laser consoles, delivery devices, consumables and service and support activities. Revenue from product sales is recognized upon receipt of a purchase order and product shipment provided that no significant obligations remain and collection of the receivables is reasonably assured. Shipments are generally made with Free-On-Board (“FOB”) shipping point terms, whereby title passes upon shipment from our dock. Any shipments with FOB receiving point terms are recorded as revenue when the shipment arrives at the receiving point. Cost is recognized as product sales revenue is recognized. The Company’s sales may include post-sales obligations for training or other deliverables. For revenue arrangements such as these, we recognize revenue in accordance with ASC 605, Revenue Recognition, Multiple-Element Arrangements. The Company allocates revenue among deliverables in multiple-element arrangements using the relative selling price method. Revenue allocated to each element is recognized when the basic revenue recognition criteria is met for each element. The Company is required to apply a hierarchy to determine the selling price to be used for allocating revenue to deliverables: (i) vendor-specific objective evidence of selling price (“VSOE”), (ii) third-party evidence of selling price (“TPE”) and (iii) best estimate of the selling price (“ESP”). In general, the Company is unable to establish VSOE or TPE for all of the elements in the arrangement; therefore, revenue is allocated to these elements based on the Company’s ESP, which the Company determines after considering multiple factors such as management approved pricing guidelines, geographic differences, market conditions, competitor pricing strategies, internal costs and gross margin objectives. These factors may vary over time depending upon the unique facts and circumstances related to each deliverable. As a result, the Company’s ESP for products and services could change. Revenues for post-sales obligations are recognized as the obligations are fulfilled.
	In international regions, we utilize distributors to market and sell our products. We recognize revenue upon shipment for sales to these independent, third party distributors as we have no continuing obligations subsequent to shipment. Generally our distributors are responsible for all marketing, sales, installation, training and warranty labor coverage for our products. Our standard terms and conditions do not provide price protection or stock retention rights to any of our distributors.
	Royalty revenues are typically based on licensees’ net sales of products that utilize our technology and are recognized as earned in accordance with the contract terms when royalties from licensees can be reliably measured and collectibility is reasonably assured, such as upon the earlier of the receipt of a royalty statement from the licensee or upon payment by the licensee.

	Recently Issued and Adopted Accounting Standards.
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2013-11, “Presentation of an Unrecognized Tax Benefit when a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” This standard requires an entity to present unrecognized tax benefits as a reduction to deferred tax assets when a net operating loss carryforward, similar tax loss or a tax credit carryforward exists, with limited exceptions. This standard is effective for fiscal years beginning on or after December 15, 2013, and for interim periods within those fiscal years. Since ASU 2013-11 only impacts financial statement disclosure requirements for unrealized tax benefits, its adoption did not have an impact on the Company’s financial position or results of operations.
	In May 2014, as part of its ongoing efforts to assist in the convergence of U.S. GAAP and International Financial Reporting Standards (“IFRS”), FASB issued ASU 2014-09, “Revenue from Contracts with Customers.” The new guidance sets forth a new five-step revenue recognition model which replaces the prior revenue recognition guidance in its entirety and is intended to eliminate numerous industry-specific pieces of revenue recognition guidance that have historically existed in U.S. GAAP. The underlying principle of the new standard is that a business or other organization will recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects what it expects in exchange for the goods or services. The standard also requires more detailed disclosures and provides additional guidance for transactions that were not addressed completely in the prior accounting guidance. The ASU provides alternative methods of initial adoption and is effective for annual and interim periods beginning after December 15, 2016. We are currently evaluating the impact that this standard will have on our consolidated financial statements.
