NOTE B – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

The Company prepares its consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. These principles require management to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, together with amounts disclosed in the related notes to the consolidated financial statements. Actual results and outcomes may differ from management’s estimates, judgments and assumptions. Significant estimates, judgments and assumptions used in these consolidated financial statements include, but are not limited to, those related to revenues, accounts receivable and related allowances, contingencies, useful lives and recovery of long-term assets and intangible assets, income taxes and valuation allowances, stock-based compensation and impairment analysis of goodwill. These estimates, judgments, and assumptions are reviewed periodically and the effects of material revisions in estimates are reflected in the consolidated financial statements prospectively from the date of the change in estimate.

Revenue Recognition

The Company recognizes revenues when (a) the price is fixed or determinable, (b) persuasive evidence of an arrangement exists, (c) the service is performed and (d) collectability of the resulting receivable is reasonably assured.

The Company’s specialized diagnostic services are performed based on a written test requisition form or electronic equivalent and revenues are recognized once the diagnostic services have been performed, and the results have been delivered to the ordering physician. These diagnostic services are billed to various payers, including Medicare, commercial insurance companies, other directly billed healthcare institutions such as hospitals and clinics, and individuals. The Company reports revenues from contracted payers, including Medicare, certain insurance companies and certain healthcare institutions, based on the contractual rate, or in the case of Medicare, published fee schedules. The Company reports revenues from non-contracted payers, including certain insurance companies and individuals, based on the amount expected to be collected. The difference between the amount billed and the amount estimated to be collected from non-contracted payers is recorded as a contractual allowance to arrive at the reported net revenues. The expected revenues from non-contracted payers are based on the historical collection experience of each payer or payer group, as appropriate. The Company records revenues from patient pay tests net of a large discount and as a result recognizes minimal revenue on those tests. The Company regularly reviews its historical collection experience for non-contracted payers and adjusts its expected revenues for current and subsequent periods accordingly.

The table below shows the adjustments made to gross service revenue to arrive at net revenues, the amount reported on our statement of operations (in thousands):


	For the Years Ended December 31,
	2014			2013			2012
Gross Service Revenues	$	224,460		$	173,784		$	157,591
Total Contractual Adjustments and Discounts		(137,391	)		(107,317	)		(97,724	)

Net Service Revenues	$	87,069		$	66,467		$	59,867

Cost of Revenue

Cost of revenue includes payroll and payroll related costs for performing tests, depreciation of laboratory equipment, rent for laboratory facilities, laboratory reagents, probes and supplies, and delivery and courier costs relating to the transportation of specimens to be tested.

Shipping Costs

The Company has a significant expense related to shipping specimens to our facility for testing and this cost is for contract couriers, commercial airline flights and charges from Federal Express to ship specimens to our facility. We had approximately $3.0 million, $2.9 million and $3.1 million in shipping expense for the years ended December 31, 2014, 2013 and 2012, respectively, and these costs were included in our cost of revenue.

Advertising Costs

Advertising costs are expensed at the time they were incurred and are not material for the years ended December 31, 2014, 2013 and 2012.

Research and Development

Research and development (“R&D”) costs are expensed as incurred. R&D expenses consist of cash and equity compensation and benefits for R&D personnel, amortization of intangibles, supplies, inventory and payment for samples to complete validation studies. These expenses were incurred to develop new genetic tests.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are comprised of amounts due from sales of the Company’s specialized diagnostic services and are recorded at the invoiced amount, net of discounts and contractual allowances. The allowance for doubtful accounts is estimated based on the aging of accounts receivable with each payer category and the historical data on bad debts in these aging categories. In addition, the allowance is adjusted periodically for other relevant factors, including regularly assessing the state of our billing operations in order to identify issues which may impact the collectability of receivables or allowance estimates. Revisions to the allowance are recorded as an adjustment to bad debt expense within general and administrative expenses. After appropriate collection efforts have been exhausted, specific receivables deemed to be uncollectible are charged against the allowance in the period they are deemed uncollectible. Recoveries of receivables previously written-off are recorded as credits to the allowance. Our estimates of net revenue are subject to change based on the contractual status and payment policies of the third party payers with whom we deal. We regularly refine our estimates in order to make our estimated revenue as accurate as possible based on our most recent collection experience with each third party payer.

Changes in the allowance for doubtful accounts are as follows (in thousands):


	Years Ended December 31,
	2014			2013			2012
Beginning balance – Allowance for Doubtful Accounts	$	4,540		$	3,002		$	2,150
Provision for doubtful accounts		2,437			2,797			3,053
Write-offs		(2,797	)		(1,259	)		(2,201	)

Ending balance – Allowance for Doubtful Accounts	$	4,180		$	4,540		$	3,002

Statements of Cash Flows

For purposes of the consolidated statements of cash flows, we consider all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.

Fair Value of Financial Instruments and Concentrations of Credit Risk

The carrying value of cash and cash equivalents, accounts receivable, accounts payable, accrued expenses and other liabilities, and other current assets and liabilities are considered reasonable estimates of their respective fair values due to their short-term nature. The Company maintains its cash and cash equivalents with domestic financial institutions that the Company believes to be of high credit standing. The Company believes that, as of December 31, 2014, its concentration of credit risk related to cash and cash equivalents was not significant. The carrying value of the Company’s long-term capital lease obligations approximates its fair value based on the current market conditions for similar instruments.

Concentrations of credit risk with respect to revenue and accounts receivable are primarily limited to certain clients and geographies to which the Company provides a significant volume of its services, and to specific payers of our services such as Medicare and individual insurance companies. The Company’s client base consists of a large number of geographically dispersed clients diversified across various customer types. For the years ended December 31, 2014, 2013 and 2012, a large oncology practice with multiple locations accounted for 10.1%, 15.8% and 14.9%, respectively, of total revenue. All other clients were less than 5% of total revenue individually. For the years ended December 31, 2014, 2013 and 2012, revenue derived from the State of Florida accounted for 25.8%, 30.6% and 33.6%, respectively, of total revenue.

Inventories

Inventories, which consist principally of testing supplies, are valued at the lower of cost or market, using the first-in, first-out method (FIFO).

Other Current Assets

As of December 31, 2014 and 2013, other current assets consist primarily of prepaid expenses.

Property and Equipment

Property and equipment are recorded at cost, net of accumulated depreciation and amortization. Property and equipment generally includes purchases of items with a cost greater than $1,000 and a useful life greater than one year. Depreciation and amortization are computed on the straight line basis over the estimated useful lives of the assets. Leasehold improvements and property and equipment under capital leases are amortized over the shorter of the related lease terms or their estimated useful lives. Costs incurred in connection with the development of internal-use software are capitalized in accordance with the accounting standard for internal-use software, and are amortized over the expected useful life of the software.

The Company periodically reviews the estimated useful lives of property and equipment. Changes to the estimated useful lives are recorded prospectively from the date of the change. Upon retirement or sale, the cost of the assets disposed of and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is included in income (loss) from operations. Repairs and maintenance costs are expensed as incurred.

Intangible Assets

Intangible assets with finite useful lives are recorded at fair value or cost, less accumulated amortization. We have four classes of intangible assets and each class of intangible assets is amortized over its estimated service period from service date for thirteen years or through the weighted average patent expiration date of each class of patents or the period of economic benefit using the straight-line method. We periodically review the estimated pattern in which the economic benefits will be consumed and adjust the amortization period and pattern to match our estimate. The Company’s intangible assets are related to the customer relationships acquired through the acquisition of Path Labs, LLC and to our license agreement with Health Discovery Corporation.

Goodwill

The Company evaluates goodwill on an annual basis in the fourth quarter or more frequently if management believes indicators of impairment exist. Such indicators could include, but are not limited to (1) a significant adverse change in legal factors or in business climate, (2) unanticipated competition, or (3) an adverse action or assessment by a regulator. 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, including goodwill. If management concludes that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, management conducts a two-step quantitative goodwill impairment test. The first step of the impairment test involves comparing the fair value of the applicable reporting unit with its carrying value. The Company estimates the fair values of its reporting units using a combination of the income, or discounted cash flows, approach and the market approach, which utilizes comparable companies’ data. If the carrying amount of a reporting unit exceeds the reporting unit’s fair value, management performs the second step of the goodwill impairment test. The second step of the goodwill impairment test involves comparing the implied fair value of the affected reporting unit’s goodwill with the carrying value of that goodwill. The amount, by which the carrying value of the goodwill exceeds its implied fair value, if any, is recognized as an impairment loss. The Company’s evaluation of goodwill completed during the year resulted in no impairment losses.

Recoverability and Impairment of Long-Lived Assets

The Company reviews the recoverability of its long-lived assets (property and equipment, and intangible assets) if events or changes in circumstances indicate the assets may be impaired. Evaluation of possible impairment is based on the Company’s ability to recover the asset from the expected future pretax cash flows (undiscounted and without interest charges) of the related operations. If the expected undiscounted pretax cash flows are less than the carrying amount of such asset, an impairment loss is recognized for the difference between the estimated fair value and carrying amount of the asset. No impairment loss was recognized in the years ended December 31, 2014, 2013 and 2012. We believe the carrying values of our long-lived assets are recoverable at December 31, 2014.

Income Taxes

We compute income taxes in accordance with ASC Topic 740, Income Taxes. Under ASC Topic 740, deferred taxes are recognized for the tax consequences of temporary differences by applying enacted statutory rates applicable to future years to differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. Also, the effect on deferred taxes of a change in tax rates is recognized in income in the period that included the enactment date. Temporary differences between financial and tax reporting arise primarily from the use of different depreciation methods and lives for property and equipment and recognition of bad debts and various other expenses that have been allowed for or accrued for financial statement purposes but are not currently deductible for income tax purposes.

The provision for income taxes, including the effective tax rate and analysis of potential tax exposure items, if any, requires significant judgment and expertise in federal and state income tax laws, regulations and strategies, including the determination of deferred tax assets and liabilities and any estimated valuation allowances deemed necessary to recognize deferred tax assets at an amount that is more likely than not to be realized. We evaluate quarterly tax positions that have been taken or are expected to be taken in our tax returns, and record a liability for uncertain tax positions, if deemed necessary. We follow a two-step approach to recognizing and measuring uncertain tax positions. First, tax positions are recognized if the weight of available evidence indicates that it is more likely than not that the position will be sustained upon examination, including resolution of related appeals or litigation processes, if any. Second, the tax position is measured as the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon settlement. We recognize interest and penalties related to unrecognized tax benefits in the provision for income taxes in the accompanying consolidated financial statements. During the years ended December 31, 2014, 2013 and 2012, we do not believe we had any significant uncertain tax positions nor did we have any provision for interest or penalties related to such positions.

Stock-Based Compensation

We account for option and stock awards under the Amended Plan in accordance with ASC Topic 718, Compensation – Stock Compensation, which requires the measurement and recognition of compensation expense in the Company’s consolidated statements of operations for all share-based option and stock awards, based on estimated grant-date fair values.

ASC Topic 718 requires us to estimate the fair value of stock-based option awards on the date of grant using an option-pricing model. The grant-date fair value of the award is recognized as expense over the requisite service period using the straight-line method. In accordance with ASC Topic 718, the estimated stock-based compensation expense to be recognized is reduced by stock option forfeitures.

We estimate the grant-date fair value of stock-based option awards using a trinomial lattice model. This model is affected by our stock price on the date of the grant as well as assumptions regarding a number of highly complex and subjective variables. These variables include the expected term of the option, expected risk-free rates of return, the expected volatility of our common stock, and expected dividend yield, each of which is more fully described below. The assumptions for expected term and expected volatility are the two assumptions that significantly affect the grant date fair value.

Expected Term: The expected term of an option is the period of time that the option is expected to be outstanding. The average expected term is determined using a trinomial lattice simulation model.

Risk-free Interest Rate: We base the risk-free interest rate used in the trinomial lattice valuation method on the implied yield at the grant date of the U.S. Treasury zero-coupon issue with an equivalent term to the stock-based award being valued. Where the expected term of a stock-based award does not correspond with the term for which a zero coupon interest rate is quoted, we use the nearest interest rate from the available maturities.

Expected Stock Price Volatility: We use our own historical weekly volatility because that is more reflective of market conditions.

Dividend Yield: Because we have never paid a dividend and do not expect to begin doing so in the foreseeable future, we have assumed a 0% dividend yield in valuing our stock-based awards.

Tax Effects of Stock-Based Compensation

We will only recognize a tax benefit from windfall tax deductions for stock-based awards in additional paid-in capital if an incremental tax benefit is realized after all other tax attributes currently available have been utilized.

Net Income Per Common Share

Basic net income per share is computed using the weighted average number of common shares outstanding during the applicable period. Diluted net income per share is computed using the weighted average number of common shares outstanding during the applicable period, plus the dilutive effect of potential common stock. Potential common stock consists of shares issuable pursuant to stock options and warrants. Calculations of net income per share are done using the treasury stock method.

Recent Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenues from Contracts with Customers. The update calls for a number of revisions in the revenue recognition rules. The update is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. Entities may use a full retrospective approach or report the cumulative effect as of the date of adoption. The Company is currently reviewing this update and has not yet determined the effect this may have on our consolidated financial statements.
