NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Cash and Cash Equivalents

The Company considers all highly liquid investments with maturities of three months or less when purchased, as cash equivalents. Cash equivalents are carried at cost, which approximates fair market value. Investments in money market funds are carried at fair value.

Restricted Cash

The Company maintains bank accounts under deposit account control agreements with Comerica Bank, to be held for repayment of lines of credit and accrued interest expense or disbursement to its operating bank account, pursuant to the terms of two revolving credit facility agreements with Comerica Bank. At December 31, 2013, there were no restricted cash amounts.

Accounts Receivable

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in its existing accounts receivable. The Company evaluates its allowance for doubtful accounts based upon its knowledge of customers and their compliance with credit terms. The evaluation process includes a review of customers’ accounts on a regular basis which incorporates input from sales, service, and finance personnel. The review process evaluates all account balances with amounts outstanding more than 90 days from due date and other specific amounts for which information obtained indicates that the balance may be uncollectible. The allowance for doubtful accounts is adjusted based on such evaluation, with a corresponding provision included in general and administrative expenses. Account balances are charged off against the allowance when it is probable the receivable will not be recovered. The Company does not have any off-balance-sheet credit exposure related to its customers.

Inventory

The Company values inventory at the lower of cost, determined using the first-in, first-out method, or market. The carrying value of inventory is evaluated periodically for excess quantities and obsolescence. Management evaluates quantities on hand, physical condition, and technical functionality as these characteristics may be impacted by anticipated customer demand for current products and new product introductions. The allowance is adjusted based on such evaluation, with a corresponding provision included in cost of revenue. Abnormal amounts of idle facility expenses, freight, handling costs and wasted material are recognized as current period charges and our allocation of fixed production overhead is based on the normal capacity of our production facilities.

Property, Plant, and Equipment

Property, plant, and equipment is stated at acquisition cost less accumulated depreciation. Maintenance and repairs are expensed as incurred. Upon sale or disposition of assets, any gain or loss is included in the consolidated statements of operations.

The cost of property, plant, and equipment is depreciated using the straight-line method over the following estimated useful lives of the respective assets, except for leasehold improvements, which are depreciated over the lesser of the estimated useful lives of the respective assets or the related lease terms.

Building	30 years
Leasehold improvements	3 to 5 years
Equipment and computers	3 to 5 years
Furniture and fixtures	5 years

Depreciation expense for the years ended December 31, 2013, 2012, and 2011 totaled approximately $484,000, $377,000, and $565,000, respectively.

Goodwill and Other Intangible Assets

Goodwill and other intangible assets with indefinite lives are not subject to amortization but are evaluated for impairment annually or whenever events or changes in circumstances indicate that the asset might be impaired. The Company operates in one operating segment and has one operating unit; therefore goodwill is tested for impairment at the consolidated level against the fair value of the Company. The fair value of a reporting unit refers to the amount at which the unit as a whole could be bought or sold in a current transaction between willing parties. Quoted market prices in active markets are the best evidence of fair value and are used as the basis for measurement, if available. Management assesses potential impairment on an annual basis on June 30^th and compares the Company’s market capitalization to its carrying amount, including goodwill. A significant decrease in the Company’s stock price could indicate a material impairment of goodwill which, after further analysis, could result in a material charge to operations. If goodwill is considered impaired, the impairment loss to be recognized is measured by the amount by which the carrying amount of the goodwill exceeds the implied fair value of that goodwill. Inherent in the Company’s fair value determinations are certain judgments and estimates, including projections of future cash flows, the discount rate reflecting the inherent risk in future cash flows, the interpretation of current economic indicators and market valuations, and strategic plans with regards to operations. A change in these underlying assumptions could cause a change in the results of the tests, which could cause the fair value of the reporting unit to be less than its respective carrying amount.

Costs incurred to acquire and successfully defend patents, and costs incurred to acquire trademarks and trade names are capitalized. Costs related to the internal development of technologies that are ultimately patented are expensed as incurred. Intangible assets, except those determined to have an indefinite life, are amortized using the straight-line method over management’s best estimate of the pattern of economic benefit over the estimated useful life of the assets. Intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable.

Long-Lived Assets

The carrying values of long-lived assets, including intangible assets subject to amortization, are reviewed when indicators of impairment, such as reductions in demand or significant economic slowdowns, are present. Reviews are performed to determine whether carrying value of an asset is impaired based on comparisons to undiscounted expected future cash flows. If this comparison indicates that there is impairment, the impaired asset is written down to fair value, which is typically calculated using discounted expected future cash flows. Impairment is based on the excess of the carrying amount over the fair value of those assets.

Other Comprehensive (Loss) Income

Other comprehensive (loss) income encompasses the change in equity from transactions and other events and circumstances from non-owner sources and is included as a component of stockholders’ equity (deficit) but is excluded from net (loss) income. Accumulated other comprehensive gain (loss) consists of the effects of foreign currency translation adjustments.

Foreign Currency Translation and Transactions

Transactions of the Company’s German, Spanish, Australian, and Indian subsidiaries are denominated in their local currencies. The results of operations and cash flows are translated at average exchange rates during the period, and assets and liabilities are translated at end-of-period exchange rates. Translation gains or losses are shown as a component of accumulated other comprehensive gain (loss) in stockholders’ equity (deficit). Gains and losses resulting from foreign currency transactions, which are denominated in a currency other than the entity’s functional currency, are included in the consolidated statements of operations.

Revenue Recognition

The Company’s products are sold domestically both directly to customers through its direct sales force and through non-exclusive distributors. Sales are recorded upon shipment and payment is generally due within 90 days or less. Internationally, the Company sells products through independent distributors. Revenue is recorded based on four basic criteria that must be met before revenue can be recognized: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred and title and the risks and rewards of ownership have been transferred to the customer or services have been rendered; (3) the price is fixed or determinable; and (4) collectability is reasonably assured. Revenue is recorded for all sales upon shipment assuming all other revenue recognition criteria are met.

Sales of the Company’s laser systems include separate deliverables consisting of the product, disposables used with the laser systems, installation, and training. The Company applies the relative selling price method, which requires that arrangement consideration be allocated at the inception of an arrangement to all deliverables using the relative selling price method. This requires the Company to use (estimated) selling prices of each of the deliverables in the total arrangement. The sum of those prices is then compared to the arrangement, and any difference is applied to the separate deliverable ratably. This method also establishes a selling price hierarchy for determining the selling price of a deliverable, which includes: (1) vendor-specific objective evidence (“VSOE”) if available, (2) third-party evidence if vendor-specific objective evidence is not available, and (3) estimated selling price if neither vendor-specific nor third-party evidence is available. VSOE is determined based on the value the Company sells the undelivered element to a customer as a stand-alone product. Revenue attributable to the undelivered elements is included in deferred revenue when the product is shipped and is recognized when the related service is performed. Disposables not shipped at time of sale and installation services are typically shipped or installed within 30 days. Training is included in deferred revenue when the product is shipped and is recognized when the related service is performed or upon expiration of time offered under the agreement, typically within six months from date of sale. The adoption of the relative selling price method does not significantly change the value of revenue recognized. Deferred revenue attributable to undelivered elements, which primarily consists of training, totaled approximately $1.8 million and $1.7 million as of December 31, 2013 and 2012, respectively.

Key judgments of the Company’s revenue recognition include the collectability of payment from the customer, the satisfaction of all elements of the arrangement having been delivered, and that no additional customer credits and discounts are needed. The Company evaluates the customer’s credit worthiness prior to the shipment of the product. Based on the assessment of the credit information available, the Company may determine the credit risk is higher than normally acceptable, and will either decline the purchase or defer the revenue until payment is reasonably assured. Future obligations required at the time of sale may also cause the Company to defer the revenue until the obligation is satisfied.

Although all sales are final, the Company accepts returns of products in certain, limited circumstances and records a provision for sales returns based on historical experience concurrent with the recognition of revenue. The sales returns allowance is recorded as a reduction of accounts receivable and revenue. As of December 31, 2013 and 2012, $110,000 and $110,000, respectively, was recorded as a reduction of accounts receivable for sales returns.

Extended warranty contracts, which are sold to laser and certain imaging customers, are recorded as revenue on a straight-line basis over the period of the contracts, which is typically one year. Included in deferred revenue for each of the years ended December 31, 2013 and 2012, was approximately $1.6 million and $1.5 million, respectively, for extended warranty contracts.

For sales transactions involving used laser trade-ins, the Company records the purchased trade-ins as inventory at the fair value of the asset surrendered with the offset to accounts receivable. In determining the estimated fair value of used laser trade-ins, Management makes an assessment of usable parts, key components, and consider the ultimate resale value of the certified pre-owned (or “CPO”) laser with applicable margins. The Company sells these CPO laser trade-ins as refurbished lasers following its laser system revenue recognition policy. Trade-in rights are not established nor negotiated with customers during the initial sales transaction of the original lasers. Trade-in rights are promotional events used at Management’s discretion to encourage existing laser customers to purchase new lasers by offering perceived discounts in exchange for customers trading in original lasers. A customer is not required to trade-in a laser nor is the Company required to accept a trade-in, however, the promotional value offered in exchange for the trade-in laser is not offered without a laser trade-in. The transaction is treated as a monetary transaction as each sale transaction involving a customer trade-in includes significant boot of greater than 25% of the fair value of the exchange. As a monetary transaction, the sale is recognized following the Company’s laser system revenue recognition policy. There have been no sales transactions in which the cash consideration was less than 25% of the total transaction value.

The Company recognizes revenue for royalties under licensing agreements for our patented technology when the product using our technology is sold. The Company estimates and recognizes the amount earned based on historical performance and current knowledge about the business operations of our licensees. Historically, the Company’s estimates have generally been consistent with amounts reported by the licensees. Licensing revenue related to exclusive licensing arrangements is recognized concurrent with the related exclusivity period and totaled $0, $0, and $64,000 for the years ended December 31, 2013, 2012, and 2011, respectively.

From time to time, the Company may offer sales incentives and promotions on its products. The cost of sales incentives are recorded at the date at which the related revenue is recognized as a reduction in revenue, increase in cost of goods sold or as a selling expense, as applicable, or later, in the case of incentives offered after the initial sale has occurred.

Provision for Warranty Expense

The Company provides warranties against defects in materials and workmanship of its laser systems for specified periods of time. WaterLase systems sold domestically are covered by the Company’s warranty for a period of one year while the Company’s Diode systems warranty period is for two years from date of sale by the Company or the distributor to the end-user. WaterLase systems sold internationally are generally covered by the Company’s warranty for a period of sixteen months while its Diode systems warranty period is up to twenty eight months from date of sale to the international distributor. Estimated warranty expenses are recorded as an accrued liability with a corresponding provision to cost of revenue. This estimate is recognized concurrent with the recognition of revenue on the sale to the distributor or end-user. Warranty expenses expected to be incurred after one year from the time of sale to the distributor are classified as a long term warranty accrual. The Company’s overall accrual is based on its historical experience and Management’s expectation of future conditions, taking into consideration the location and type of customer and the type of laser, which directly correlate to the materials and components under warranty, the duration of the warranty period, and the logistical costs to service the warranty. Additional factors that may impact the Company’s warranty accrual include changes in the quality of materials, leadership and training of the production and services departments, knowledge of the lasers and workmanship, training of customers, and adherence to the warranty policies. Additionally, an increase in warranty claims or in the costs associated with servicing those claims would likely result in an increase in the accrual and a decrease in gross profit. The Company offers extended warranties on certain imaging products; however, all imaging products are initially covered by the manufacturer’s warranties.

Changes in the initial product warranty accrual and the expenses incurred under our initial and extended warranties for the years ended December 31 were as follows (in thousands):

	Years Ended December 31,
	2013			2012			2011
Initial warranty accrual, beginning balance	$	1,699		$	2,218		$	2,725
Provision for estimated warranty cost		475			1,705			1,586
Warranty expenditures		(1,078	)		(2,224	)		(2,093	)
Initial warranty accrual, ending balance		1,096			1,699			2,218
Total warranty accrual, long term		—			—			—
Total warranty accrual, current portion	$	1,096		$	1,699		$	2,218

Shipping and Handling Costs and Revenues

Shipping and handling costs are expensed as incurred and are recorded as a component of cost of revenue. Charges to customers for shipping and handling are included as a component of revenue.

Advertising Costs

Advertising costs are expensed as incurred and totaled approximately $1.5 million, $907,000, and $444,000 for the years ended December 31, 2013, 2012, and 2011, respectively.

Engineering and Development

Engineering and development expenses are generally expensed as incurred and consist of engineering personnel salaries and benefits, prototype supplies, contract services and consulting fees related to product development.

Stock-Based Compensation

During the years ended December 31, 2013, 2012, and 2011, the Company recognized compensation cost related to stock options of $1.6 million, $1.6 million, and $1.5 million, respectively, based on the grant date fair value. The net impact to earnings for the years ended December 31, 2013, 2012, and 2011, was $(0.05), $(0.05), and $(0.05) per diluted share, respectively. The following table summarizes the income statement classification of compensation expense associated with share-based payments (in thousands):

	Years Ended December 31,
	2013		2012		2011
Cost of revenue	$	288	$	245	$	175
Sales and marketing		585		514		463
General and administrative		594		668		751
Engineering and development		142		173		139
	$	1,609	$	1,600	$	1,528

As of December 31, 2013 and 2012, the Company had $2.7 million and $1.9 million, respectively, of total unrecognized compensation cost, net of estimated forfeitures, related to unvested share-based compensation arrangements granted under our existing plans. The cost is expected to be recognized over a weighted average period of 1.5 years.

The Black-Scholes option valuation model is used in estimating the fair value of traded options. This option pricing model requires the Company to make several assumptions regarding the key variables used to calculate the fair value of its stock options. The risk-free interest rate used is based on the U.S. Treasury yield curve in effect for the expected lives of the options at their dates of grant. Since July 1, 2005, the Company has used a dividend yield of zero as it does not intend to pay cash dividends on its common stock in the foreseeable future. The most critical assumption used in calculating the fair value of stock options is the expected volatility of the Company’s common stock. Management believes that the historic volatility of the Company’s common stock is a reliable indicator of future volatility, and accordingly, a stock volatility factor based on the historical volatility of the Company’s common stock over a period of time is used in approximating the estimated volatility of new stock options. The expected term is estimated by analyzing the Company’s historical share option exercise experience over a five year period. Compensation expense is recognized using the straight-line method for all stock-based awards. Compensation expense is recognized only for those options expected to vest, with forfeitures estimated at the date of grant based on historical experience and future expectations. Forfeitures are estimated at the time of the grant and revised as necessary in subsequent periods if actual forfeitures differ from those estimates.

The stock option fair values were estimated using the Black-Scholes option-pricing model with the following assumptions:

	2013			2012			2011
Expected term (years)		3.65			3.70			4.15
Volatility		84	%		97	%		105	%
Annual dividend per share	$	0.00		$	0.00		$	0.00
Risk-free interest rate		1.04	%		0.77	%		1.53	%

Excise Tax

Commencing January 1, 2013, certain of the Company’s product sales are subject to the newly enacted medical device excise tax. The Company has included such taxes separately as a component of operating expense.

Income Taxes

Differences between accounting for income taxes for financial statement purposes and accounting for tax return purposes are stated as deferred tax assets or deferred tax liabilities in the accompanying consolidated financial statements. The provision for income taxes represents the tax payable for the period and the change during the period in deferred tax assets and liabilities. The Company establishes a valuation allowance when it is more likely than not that the deferred tax assets will not be realized.

On January 1, 2007, the Company adopted the interpretations issued by the Financial Accounting Standards Board (“FASB”) which establishes a single model to address accounting for uncertain tax positions. The interpretations clarify the accounting for income taxes by prescribing a minimum recognition threshold a tax position is required to meet before being recognized in the financial statements and also provides guidance on de-recognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition.

The income tax provision for the year ended December 31, 2013 was calculated using the discrete year-to-date method, which management determined to be more appropriate than the annual effective rate method which was used to calculate the income tax provision for the quarter ended March 31, 2013. See Note 6 – Income Taxes for additional disclosures related to the Company’s income tax.

Net Loss Per Share — Basic and Diluted

Basic net income (loss) per share is computed by dividing income (loss) available to common stockholders by the weighted-average number of common shares outstanding for the period. In computing diluted net income (loss) per share, the weighted average number of shares outstanding is adjusted to reflect the effect of potentially dilutive securities. Common shares outstanding, as included in the calculation of basic and diluted loss per share, includes retroactive adjustments to reflect increases resulting from stock dividends that have been paid through the date that these financial statements are issued.

Outstanding stock options and warrants to purchase approximately 6,039,000, 4,713,000, and 4,626,000 shares were not included in the calculation of diluted loss per share amounts for the years ended December 31, 2013, 2012, and 2011, respectively, as their effect would have been anti-dilutive.

Recent Accounting Pronouncements

Changes to U.S. GAAP are established by the FASB in the form of accounting standards updates (“ASU’s”) to the FASB’s Accounting Standards Codification (“ASC”).

The Company considers the applicability and impact of all ASU’s. ASU’s not listed below were assessed and determined to not be applicable or are expected to have minimal impact on our consolidated financial position and results of operations.

Newly Adopted Accounting Standards

In July 2012, the FASB simplified guidance for testing for impairment of indefinite-lived intangible assets other than goodwill. The changes are intended to reduce compliance costs. The revised guidance allows a qualitative approach for testing indefinite-lived intangible assets for impairment, similar to the recently issued impairment testing guidance for goodwill and allows the option to first assess qualitative factors (events and circumstances) that could have affected the significant inputs used in determining the fair value of the indefinite-lived intangible asset to determine whether it is more likely than not (meaning a likelihood of more than 50 percent) that the indefinite-lived intangible asset is impaired. An organization may choose to bypass the qualitative assessment for any indefinite-lived intangible asset in any period and proceed directly to calculating its fair value. The amendments are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. The adoption did not have a material impact on the Company’s consolidated financial statements.

In February 2013, the FASB issued guidance for reporting of amounts reclassified out of accumulated other comprehensive income. The revised guidance requires reporting the effect of significant reclassifications out of accumulated other comprehensive income on the respective line items in net income if the amount being reclassified is required to be reclassified in its entirety to net income. For other amounts that are not required to be reclassified in their entirety to net income in the same reporting period, an entity is required to cross-reference other disclosures that provide additional detail about these amounts. The amendments do not change the current requirements for reporting net income or other comprehensive income in financial statements. The guidance is effective prospectively for reporting periods beginning after December 15, 2012. The adoption did not have a material impact on the Company’s consolidated financial statements.

Accounting Standards not yet Adopted

In March 2013, the FASB issued guidance on a parent’s accounting for the cumulative translation adjustment upon de-recognition of certain subsidiaries or groups of assets within a foreign entity or of an investment in a foreign entity. The revised guidance requires that the parent release any related cumulative translation adjustment into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. The guidance is effective prospectively for reporting periods beginning after December 15, 2013. Early adoption is permitted. Management believes that the adoption of this guidance will not have a material impact on the Company’s consolidated financial statements.

In July 2013, the FASB issued guidance to address the diversity in practice related to the financial statement presentation of unrecognized tax benefits as either a reduction of a deferred tax asset or liability when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. This guidance is effective prospectively for reporting periods beginning after December 15, 2013. Early adoption is permitted. Management believes that the adoption of this guidance will not have a material impact on the Company’s consolidated financial statements.
