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 January 2, 2016, which was filed with the SEC on March 31, 2016.

Financial Statement Presentation.

The unaudited condensed 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 unaudited condensed consolidated financial statements in conformity with U.S. 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 collectibility 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 Accounting Standards Codification (“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.

Concentration of Credit Risk.

Our cash and cash equivalents are deposited in demand and money market accounts. Deposits held with banks may exceed the amount of insurance provided on such deposits. Generally these deposits may be redeemed upon demand and therefore, bear minimal risk.

We market our products to distributors and end-users throughout the world. Sales to international distributors are generally made on open credit terms and letters of credit. Management performs ongoing credit evaluations of our customers and maintains an allowance for potential credit losses. Historically, we have not experienced any significant losses related to individual customers or a group of customers in any particular geographic area. For the three and six month periods ended July 2, 2016 and July 4, 2015, no single customer accounted for 10% of total revenues. As of July 2, 2016, no customer accounted for approximately 10% of our accounts receivable and as of January 2, 2016, no customer accounted for more than 10% of our accounts receivable.

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 condensed 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 July 2, 2016 and July 4, 2015 is as follows:

	Six Months Ended
(in thousands)	July 2, 2016			July 4, 2015
Balance, beginning of period	$	1,311		$	1,179
Additions to deferral		640			687
Revenue recognized		(680	)		(667	)
Balance, end of period	$	1,271		$	1,199

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 July 2, 2016 and July 4, 2015 is as follows:

	Six Months Ended
(in thousands)	July 2, 2016			July 4, 2015
Balance, beginning of period	$	603		$	469
Accruals for product warranties		232			183
Cost of warranty claims and adjustments		(225	)		(132	)
Balance, end of period	$	610		$	520

Recently Issued and Adopted Accounting Standards.

In May 2014, as part of its ongoing efforts to assist in the convergence of U.S. GAAP and International Financial Reporting Standards (“IFRS”), the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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. In August 2015, the FASB issued ASU 2015-14, “Revenue from Contracts with Customers, Deferral of the Effective Date”. The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. Early adoption is permitted for annual periods beginning after December 15, 2016. We are currently evaluating the impact that this standard will have on the Company’s consolidated financial statements.

In June 2014, the FASB issued ASU 2014-12, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period (a consensus of the FASB Emerging Issues Task Force)”. The ASU clarifies that entities should treat performance targets that can be met after the requisite service period of a share-based payment award as performance conditions that affect vesting. Therefore, an entity would not record compensation expense (measured as of the grant date without taking into account the effect of the performance target) related to an award for which transfer to the employee is contingent on the entity’s satisfaction of a performance target until it becomes probable that the performance target will be met. The ASU does not contain any new disclosure requirements. The ASU is effective for reporting periods beginning after December 15, 2015. We adopted this standard at the beginning of fiscal 2016 and it did not have a material impact on the Company’s consolidated financial statements.

In July 2015, the FASB issued ASU 2015-11, “Simplifying the Measurement of Inventory.” Under this ASU, inventory will be measured at the “lower of cost and net realizable value” and options that currently exist for “market value” will be eliminated. The ASU defines net realizable value as the “estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.” No other changes were made to the current guidance on inventory measurement. ASU 2015-11 is effective for interim and annual periods beginning after December 15, 2016. Early application is permitted and should be applied prospectively. Management is evaluating the provisions of this statement, including which period to adopt, and has not determined what impact the adoption of this standard will have on the Company’s consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, "Leases," amending ASC 842. This ASU requires the Company to recognize on the balance sheet the assets and liabilities for the rights and obligations created by leases with terms of more than twelve months. This ASU also requires disclosures enabling the users of financial statements to understand the amount, timing and uncertainty of cash flows arising from leases. This new standard will become effective for the Company for annual periods beginning after December 15, 2018 (including interim reporting periods within those periods). Early adoption is permitted as of the beginning of an interim or annual reporting period. We are currently evaluating the impact of this new standard on the Company’s consolidated financial statements.

In March 2016, the FASB issued Accounting Standards Update ASU 2016-09, "Improvements to Employee Share-Based Payment Accounting." This ASU affects entities that issue share-based payment awards to their employees. The ASU is designed to simplify several aspects of accounting for share-based payment award transactions, which include the income tax consequences, classification of awards as either equity or liabilities, classification on the statement of cash flows and forfeiture rate calculations. This ASU will become effective for the Company on December 15, 2016 (including interim reporting periods within those periods). Early adoption is permitted in any interim or annual period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the same period. We are currently evaluating the impact of this new standard on the Company’s consolidated financial statements.

In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606), which amended certain aspects of the FASB's new revenue standard, ASU No. 2014-09, Revenue from Contracts with Customers. The standard should be adopted concurrently with adoption of ASU 2014-09 which is effective for annual and interim periods beginning after December 15, 2017. We have not yet selected a transition method nor have we determined the effect of the standard on the Company’s ongoing financial reporting.

In May 2016, the FASB issued ASU No. 2016-12 which amended the revenue recognition guidance regarding collectability, noncash consideration, presentation of sales tax and transition. This ASU is effective during the same period as ASU 2014-09. We are currently evaluating the impact of this guidance on the Company’s consolidated financial statements.
