1. Organization, Operations and Basis of Accounting

Response Genetics, Inc. (the “Company”) was incorporated in the State of Delaware on September 23, 1999 as Bio Type, Inc. for the purpose of providing molecular profiling services of tumor tissue that has been formalin-fixed and embedded in paraffin. In August 2000, the Company changed its name to Response Genetics, Inc.

The Company is a life science company engaged in the research, development, marketing and sale of pharmacogenomics-clinical diagnostic tests for cancer. Pharmacogenomics is the science of how an individual’s genetic makeup relates to drug response. Diagnostic tests based on pharmacogenomics facilitate the prediction of a response to drug therapy or survival following surgery based on an individual’s genetic makeup. In order to generate pharmacogenomic information from patient specimens for these tests, the Company uses its proprietary technologies that enable the Company to reliably and consistently extract ribonucleic acid (“RNA”) and deoxyribonucleic acid (“DNA”) from tumor specimens that are stored as formalin-fixed and paraffin-embedded (“FFPE”) specimens and, thereby to analyze genetic information contained in these tissues for each patient. The Company’s platforms include analysis of single biomarkers using the polymerase chain reaction method as well as global gene interrogation using microarray methods and fluorescence in situ hybridization (“FISH”) from paraffin or frozen tissue specimens. The Company primarily derives its revenue from the sale of its ResponseDX^® diagnostic testing products and by providing pharmacogenomic clinical trial testing services to pharmaceutical companies in the United States, Asia and Europe.

The Company’s goal is to provide cancer patients and their physicians with a means to make informed, individualized treatment decisions based on genetic analysis of tumor tissues. The Company’s pharmacogenomic analysis of clinical trial specimens for the pharmaceutical industry may provide data that will lead to a better understanding of the molecular basis for response to specific drugs and, therefore lead to individualized treatment.

Liquidity and Management’s Plans

Since its inception, the Company has devoted substantial effort in developing its products and has incurred losses and negative cash flows from operations. At March 31, 2015, the Company had an accumulated deficit of $83,014,921. The Company anticipates continued losses and negative cash flows as it funds its selling and marketing activities and research and development programs.

The Company’s current operating plan includes various assumptions concerning the level and timing of cash receipts from sales and cash outlays for operating expenses and capital expenditures. The Company’s ability to successfully carry out its business plan is primarily dependent upon its ability to (1) obtain sufficient additional capital at acceptable costs, (2) attract and retain knowledgeable employees and (3) generate significant additional revenues. At this time, the Company expects to satisfy its future cash needs primarily through additional financing and/or strategic alternatives. The Company is currently seeking such additional financing and/or strategic alternatives; however, there can be no assurance that any additional financing or strategic alternatives will be available on acceptable terms, if at all. If the Company is unable to timely and successfully raise additional capital, implement strategic alternatives and/or achieve profitability, it will not have sufficient capital resources to implement its business plan or continue its operations, and the Company will most likely be required to reduce certain spending and/or curtail operations, which could have a material adverse effect on the Company’s ability to achieve its intended business objectives. These matters raise substantial doubt about the Company’s ability to continue as a going concern. No adjustments have been made to the accompanying unaudited condensed consolidated financial statements to reflect any of the matters discussed above.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with the instructions for Form 10-Q promulgated by the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the fiscal year. The balances as of December 31, 2014 were derived from our audited financial statements as of December 31, 2014. The financial statements should be read in conjunction with the Company’s audited December 31, 2014 and 2013 consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K previously filed with the SEC on March 31, 2015.

2. Summary of Significant Accounting Policies

Basis of Consolidation

The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Response Genetics, Ltd., a Scottish corporation (the “Subsidiary”), which was incorporated in November 2006. The Subsidiary had no employees or active operations in 2014 or to date in 2015. All significant intercompany transactions and balances have been eliminated in consolidation.

Cash and Cash Equivalents

The Company considers all highly liquid investments with a maturity date of three months or less from the date of purchase to be cash equivalents. The carrying value of cash equivalents approximates fair value due to the short-term nature and liquidity of these instruments. The Company’s cash equivalents are comprised of cash on hand, deposits in banks and money market investments.

2. Summary of Significant Accounting Policies (continued)

Accounts Receivable

Pharmaceutical Accounts Receivable

The Company invoices its clients as specimens are processed and any other contractual obligations are met. The Company’s contracts with clients typically require payment within 45 days of the date of invoice. The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of its clients to make required payments. The Company specifically analyzes accounts receivable and historical bad debts, client credit, current economic trends and changes in client payment trends when evaluating the adequacy of the allowance for doubtful accounts. Account balances are charged-off against the allowance when it is probable the receivable will not be recovered. To date, the Company’s pharmaceutical customers have primarily been large pharmaceutical companies. As a result, bad debts from pharmaceutical accounts receivable to date have been minimal. Pharmaceutical company accounts receivable as of December 31, 2014 and March 31, 2015 were $1,037,834 and $454,773, respectively. There were no allowances for doubtful accounts recorded against these pharmaceutical accounts receivable at December 31, 2014 and March 31, 2015.

ResponseDX^® Accounts Receivable

ResponseDX^® accounts receivable are recorded from two primary payors: (1) Medicare and (2) third party payors such as commercial insurance and private payors or self-paying payors (“Private Payors”). ResponseDX^® accounts receivable are recorded at established billing rates less an estimated billing adjustment, based on reporting models utilizing historical cash collection percentages and updated for current effective reimbursement factors.  Management performs ongoing valuations of accounts receivable balances based on management’s evaluation of historical collection experience and industry trends.  Based on the historical experience for our accounts, management has determined, based on a detailed analysis, that accounts receivable associated with certain billings are unlikely to be collected. Therefore, the Company has recorded an allowance for doubtful accounts of $2,071,706 and $2,226,890 as of December 31, 2014 and March 31, 2015, respectively. The Company’s bad debt expense for the three months ended March 31, 2014 and 2015 was $1,293,850 and $1,902,144, respectively.

ResponseDX^® accounts receivable as of December 31, 2014 and March 31, 2015, consisted of the following:

	December 31, 2014			March 31, 2015
Net Medicare receivable	$	2,814,989		$	2,191,781
Net Private Payor receivable		6,029,300			5,639,447
		8,844,289			7,831,228
Allowance for doubtful accounts		(2,071,706	)		(2,226,890	)
Total	$	6,772,583		$	5,604,338

At December 31, 2014 and March 31, 2015, all Medicare accounts receivable outstanding for a period of greater than one year have been reserved 100%.

Property and Equipment

Property and equipment are carried at cost less accumulated depreciation and amortization. Depreciation and amortization are calculated using the straight-line methods over the estimated useful lives of the assets. The Company has determined the estimated useful lives of its property and equipment, as follows:

Laboratory equipment	5 to 7 years
Furniture and equipment	3 to 7 years
Purchased and internally-developed software	3 to 5 years
Leasehold improvements	Shorter of the useful life (5 to 7 years) or the lease term

Maintenance and repairs are charged to expense as incurred. The cost and accumulated depreciation of assets sold or otherwise disposed of are removed from the related accounts and the resulting gain or loss is reflected in the statements of operations. The Company has capitalized costs related to the development of database software (see Note 3). The portion of this database placed into service is amortized in accordance with ASC 350-40, Internal-Use Software. The amortization period is five years using the straight-line method.

Revenue Recognition

Pharmaceutical Revenue

Revenues that are derived from testing services provided to pharmaceutical companies are recognized on a contract specific basis pursuant to the terms of the related agreements. Revenue is recognized in accordance with ASC 605, Revenue Recognition, which requires that four basic criteria must be met before revenue can be recognized: (1) persuasive evidence that an arrangement exists; (2) delivery has occurred and title and the risks and rewards of ownership have been transferred to the client or services have been rendered; (3) the price is fixed or determinable; and (4) collectability is reasonably assured.

Revenues are recorded on an accrual basis as the contractual obligations are completed and as a set of assays is processed through the Company’s laboratory under a specified contractual protocol and are recorded on the date the tests are completed. Certain contracts have minimum assay requirements that, if not met, result in payments that are due upon the completion of the designated period. In these cases, revenues are recognized when the end of the specified contract period is reached.

On occasion, the Company may enter into a contract that requires the client to provide an advance payment for specimens that will be processed at a later date. In these cases, the Company records this advance as deferred revenue and recognizes the revenue as the specimens are processed or at the end of the contract period, as appropriate. There was no deferred revenue at December 31, 2014 or March 31, 2015.

The Company recorded revenue from pharmaceutical clients for the three months ended March 31, 2014 and 2015 of $577,381 and $462,093, respectively.

ResponseDX^® Revenue

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.

Services are provided to certain patients covered by various third-party payer programs including various managed care organizations, commercial insurance plans and Medicare programs. Billings for services under third-party payer programs are included in revenue net of allowances for contractual discounts and allowances for differences between the amounts billed and estimated payment amounts. Significant judgment is inherent in the selection of assumptions and the interpretation of historical experience as well as the identification of external and internal factors affecting the determination of these reserves for Medicare, private health insurance companies, healthcare institutions, and patients.

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 assumptions used to determine these contractual allowances are reasonable considering known facts and circumstances. If actual future payments are less than the estimates the Company made at the time of recognizing revenue, the consolidated financial position, results of operations and cash flows may be negatively impacted. If actual future payments are materially different from the contracted amounts or estimates, the difference is accounted for as a change in estimate in the period in which they become known. Adjustments to the estimated payment amounts based on final settlement are recorded upon settlement as an adjustment to revenue.

For the three months ended March 31, 2014 and 2015, approximately 39% and 42%, respectively, of the Company's ResponseDX^® revenues were derived directly from the Medicare program. The Company’s Medicare provider number allows it to invoice and collect from Medicare. The Company’s invoicing to Medicare is primarily based on amounts allowed by Medicare for the service provided as defined by Common Procedural Terminology (“CPT”). Laws and regulations governing the Medicare program and healthcare generally are complex and subject to interpretation.

The following details ResponseDX^® revenue for the periods indicated:

	Three Months
	Ended March 31,
	2014		2015
Net Medicare revenue	$	1,308,422	$	1,408,241

2. Summary of Significant Accounting Policies - (continued)

Revenue Recognition – (continued)

The Company recognizes revenue for services covered by Medicare based on the Medicare fee schedule. For 2014, the Company’s Medicare fees were based on the Centers for Medicare and Medicaid Services (“CMS”) proposed “Medicare Program; Revisions to Payment Policies under the Physician Fee Schedule, Clinical Laboratory Fee Schedule & Other Revisions to Part B for CY 2014” released in July 2013. For the three months ended March 31, 2015, the Company’s fees were based on the Centers for Medicare and Medicaid Services (“CMS”) fee schedules released in December 2014.

The Company updates its estimates of Medicare fees based on current information from CMS. The nature of the testing services the Company provides, the evidence the Company gathers to establish the creditworthiness of its payors and the delivery method of its services have not changed from prior periods, and therefore these assumption remain appropriate.

Cost of Revenue

Cost of revenue represents the cost of materials, direct labor, royalties, costs associated with processing tissue specimens including pathological review, staining, microdissection, paraffin extraction, reverse transcription polymerase chain reaction (“PCR”), fluorescence in situ hybridization (“FISH”), quality control analyses, license fees and delivery charges necessary to render an individualized test result. Costs associated with performing tests are recorded as the tests are processed.

License Fees

The Company has licensed technology for the extraction of ribonucleic acid (“RNA”) from formalin-fixed, paraffin-embedded tumor specimens from the University of Southern California (“USC”). Under the terms of the license agreement, the Company is required to pay royalties to USC calculated as a fixed percentage of the net sales price as defined in the agreement that the Company generates by using this technology. Total license fees expensed in cost of revenue under the license agreement with USC were $10,961 and $5,508 for the three months ended March 31, 2014 and 2015, respectively. The Company also maintains a non-exclusive license to use certain patents related to the PCR of Roche Molecular Systems, Inc. (“Roche”). The Company pays Roche a royalty fee based on revenue that the Company generates through use of this technology. The Company accrues for such royalties at the time revenue is recognized. Royalties expensed in cost of revenue under the Roche agreement totaled $44,373 and $16,265 for the three months ended March 31, 2014 and 2015, respectively. Such royalties are included in cost of revenues in the accompanying statements of operations.

The Company is subject to potentially significant variations in royalties recorded in any period. While the amount paid is based on a fixed percentage of net sales price as defined in the agreement of specific tests pursuant to terms set forth in the agreements with USC and Roche, the amount due is calculated based on the revenue we recognize using the respective licensed technology. As discussed above, this revenue can vary from period to period as it is dependent on the timing of the specimens submitted by our clients for testing.

Additionally, the Company periodically analyzes the technical procedures performed in its test offerings to assess which activities utilize licensed technologies and to calculate royalties for use of the licensed technology. The most recent analyses indicate that the Company could owe less than the amounts that have been accrued for royalties payable. Roche is still reviewing the Company’s updated royalty calculations. It is possible that based on Roche’s review and the Company’s discussions with Roche, the Company may further adjust its Roche royalty accrual.

Research and Development

The Company expenses costs associated with research and development activities as incurred. Research and development costs are expensed as incurred and classified as research and development costs. Research and development costs include employee costs (salaries, payroll taxes, benefits, and travel), equipment depreciation and maintenance, laboratory supplies, primers and probes, reagents, patent costs and occupancy costs.

Line of Credit

On July 14, 2011, the Company entered into a line of credit agreement with Silicon Valley Bank (the “Bank”), which agreement has been amended most recently on July 30, 2014. The line of credit is collateralized by all of the Company’s assets including its pharmaceutical, Private Payor and Medicare receivables. The maximum amount that can be borrowed from the line of credit is $2,000,000, subject to certain conditions. As of December 31, 2014 and March 31, 2015, the Company had drawn $1,500,000 and $1,465,662, respectively, against the line of credit. As of December 31, 2014 and March 31, 2015, the available amount the Company can draw from the line of credit was $500,000 and $463,677, respectively, calculated as the lesser of (i) the Company’s calculated borrowing base, which was 80% of certain of the Company’s accounts receivable, or (ii) the amount available under the line of credit. During the first half of 2014, the interest rate charged to the Company on the line of credit was 5%, calculated by reference to the prime rate plus 1.75%. For the latter half of 2014 and the three months ended March 31, 2015, the interest rate charged to the Company was 5.5%, calculated by reference to the prime rate plus 2.25%. The line of credit’s maturity date is July 25, 2016.

The line of credit is subject to various covenants, including financial covenants that require the Company to maintain (i) an adjusted quick ratio of at least 1.25 to 1.00; (ii) quarterly rolling twelve-month net revenue balances beginning December 31, 2014; and (iii) quarterly minimum liquidity of $1,000,000. The Company’s revenue covenant and liquidity covenant under the line of credit agreement conform with, and are cross-defaulted with, equivalent covenants under the SWK Credit Agreement (as described below). At December 31, 2014 and March 31, 2015, the Company was in compliance with its covenants under the line of credit agreement. Historically, however, the Company has been out of compliance with certain covenants from time to time, and the Company has received waivers and forbearance agreements from the Bank.

From time to time, the Company’s calculated borrowing base under its Bank line of credit may decrease to a level where the Company is in an over-advance position in which case the Company will be required to repay any outstanding amounts greater than the calculated borrowing base for such covered period back to the Bank immediately. The Company will be able to draw down on the credit line again with respect to such paid-back amount once the Company is in compliance with the borrowing base requirement.

As of December 31, 2014 and March 31, 2015, the line of credit under the credit agreement was classified as a non-current liability of the Company on the accompanying condensed consolidated balance sheet as the line of credit had a maturity date of greater than one year from the date of the balance sheet.

SWK Term Loan

On July 30, 2014 (the “Closing Date”), the Company entered into a credit agreement (the “SWK Credit Agreement”) with SWK Funding LLC, as the administrative agent (the “Agent” or “SWK”), and the lenders (including SWK) party thereto from time to time (the “Lenders”). The SWK Credit Agreement provides for a multi-draw term loan to the Company (the “Loan”) up to a maximum principal amount of $12,000,000 (the “Loan Commitment Amount”). On the Closing Date, the Lenders advanced the Company an amount equal to $8,500,000 which is due and payable on July 30, 2020 (the “Term Loan Maturity Date”) or such earlier date on which the Loan Commitment Amount is terminated pursuant to the terms of the SWK Credit Agreement. On February 3, 2015 (the “Amendment Closing Date”), the Company and SWK entered into a first amendment (the “Amendment”) to the SWK Credit Agreement.  Pursuant to the Amendment, the Company drew an additional $1,500,000 of the Loan Commitment Amount thereby increasing the total amount advanced to the Company under the SWK Credit Agreement to $10,000,000.

The Loan bears interest at a rate equal to the LIBOR Rate (as defined in the SWK Credit Agreement) plus an applicable margin of 12.5% per annum, subject to a one percent (1.0%) LIBOR floor. Interest on the Loan is due and payable in arrears (i) on the forty-fifth (45th) day following the last calendar day of each of the months of September, December, March, and June, commencing on November 15, 2014, (ii) upon a prepayment of the Loan and (iii) on the Term Loan Maturity Date. At December 31, 2014 and March 31, 2015, the interest rate charged to the Company was 13.5%. Upon the earlier of (a) the Term Loan Maturity Date or (b) full repayment of the Loan, the Company is also required to pay an exit fee. On September 9, 2014, SWK, in its capacity as the initial Lender, assigned part of its interests under the SWK Credit Agreement to SG-Financial, LLC (“SG”). Pursuant to the assignment, SG was assigned $2,500,000 of the $8,500,000 Closing Date initial advance to the Company and $1,029,412 of the subsequent term loan commitment. On January 30, 2015, SG assigned all of its interests under the SWK Credit Agreement back to SWK.

On the Closing Date, the Company issued to the Agent a warrant (the “Initial Warrant”) to purchase up to 681,090 shares of the Company's common stock. The Initial Warrant was exercisable, in whole or in part, from the date of issuance until and including July 30, 2020 at an exercise price of $0.936 per share, subject to adjustment. The Initial Warrant was valued at $414,239, or approximately $0.61 per covered share, using a Black-Scholes pricing model with the following assumptions: 2.01% risk free rate, 0% dividend, 101.5% volatility, and six-year expected life. The value of the warrant was recorded on the balance sheet included in additional paid-in capital. On September 9, 2014, the Agent assigned a portion of the Initial Warrant consisting of the right to purchase 200,321 shares of common stock to SG (the “SG Initial Warrant”). On January 30, 2015, SG assigned the SG Initial Warrant back to the Agent and on the Amendment Closing Date, the Company replaced the Initial Warrant to purchase the total 681,090 shares of the Company’s common stock with a new warrant with an adjusted exercise price (the “Replacement Warrant”).   The Replacement Warrant is exercisable up to and including July 30, 2020 at an exercise price of $0.39 per share.  The Agent may exercise the Replacement Warrant on a cashless basis at any time.  In the event the Agent exercises the Replacement Warrant on a cashless basis, the Company will not receive any proceeds.  The exercise price of the Replacement Warrant is subject to customary adjustments for stock splits, stock dividends, recapitalizations and the like.

2. Summary of Significant Accounting Policies (continued)

For accounting purposes, the proceeds received in the July 2014 transaction were allocated to the liability for debt, a debt issuance discount and additional paid-in capital for the warrant based upon the relative fair value of the loan and the warrant. The amounts recorded in the financial statements were $8,500,000 for loan liability, $576,161 for debt issuance discount and $377,140 to additional paid-in capital for the warrant. Additionally, the Company recorded deferred loan issuance costs of $187,092 for investment banker fees and legal fees incurred to enter into the SWK Credit Agreement. The debt issuance discount and the deferred issuance costs are being amortized to interest expense over the six-year term of the loan. Upon the re-issuance of the Replacement Warrant on February 3, 2015 at a reduced exercise price of $0.39, the debt issuance discount was re-valued at $599,305 and a $23,144 increase in the warrant value was recorded as an increase to debt discount and additional paid-in capital. The Replacement Warrant transaction was determined to be a debt modification.

In addition, on the Amendment Closing Date, the Company issued the Agent a new warrant (the “First Amendment Warrant”) to purchase 576,923 shares of Common Stock.  The First Amendment Warrant is exercisable up to and including February 3, 2021 at an exercise price of $0.39 per share, subject to adjustment.  The First Amendment Warrant was valued at $167,712, or approximately $0.29 per covered share, using a Black-Scholes pricing model with the following assumptions: 1.39% risk free rate, 0% dividend, 90.9% volatility and six-year expected life. The value of the warrant was recorded on the balance sheet included in additional paid-in capital. The Agent may exercise the First Amendment Warrant on a cashless basis at any time.  In the event the Agent exercises the First Amendment Warrant on a cashless basis, the Company will not receive any proceeds.  The exercise price of the First Amendment Warrant is subject to customary adjustments for stock splits, stock dividends, recapitalizations and the like.

Additionally, for accounting purposes, the proceeds received in the February 2015 transaction were allocated to the liability for debt, a debt issuance discount and additional paid-in capital for the warrant based upon the relative fair value of the loan and the warrant. The amounts recorded in the financial statements were $1,500,000 for loan liability, $168,372 for debt issuance discount and $148,887 to additional paid-in capital for the warrant. Additionally, the Company recorded deferred loan issuance costs of $19,485 for investment banker fees and legal fees incurred to enter into the Amendment. The debt issuance discount and the deferred issuance costs are being amortized to interest expense over the six-year term of the loan.

The Company may prepay the Loan, in whole or in part, upon five business days’ written notice provided that a prepayment premium is paid to the Lenders as set forth in the SWK Credit Agreement. The Company is required to prepay the Loan with any net cash proceeds received from certain types of dispositions of assets described in the SWK Credit Agreement. The Company is also required to make certain revenue-based payments on the Company’s quarterly revenues, applied in the following priority: (i) first, to the payment of all fees, costs, expenses and indemnities due and owing to the Agent under the SWK Credit Agreement, (ii) second, to the payment of all fees, costs, expenses and indemnities due and owing to the Lenders under the SWK Credit Agreement, (iii) third, to the payment of all accrued but unpaid interest until paid in full, (iv) fourth, for each revenue-based payment date after August 2016, to the payment of all principal of the Loan up to an aggregate amount of $750,000 on any such payment date and (v) fifth, all remaining amounts to the Company.

As of December 31, 2014 and March 31, 2015, the term debt under the SWK Credit Agreement was classified as a non-current liability of the Company on the accompanying balance sheet as the repayment terms are based on future revenues that cannot be reasonably estimated and therefore all outstanding amounts are classified as non-current.

The SWK Credit Agreement contains customary affirmative and negative covenants for credit facilities of its type, including covenants that limit the Company’s ability to pay dividends or redeem outstanding equity interests, incur additional indebtedness, grant additional liens, engage in any other type of business, make investments, merge, consolidate or sell all or substantially all of its assets and enter into transactions with related parties. The SWK Credit Agreement also contains certain financial covenants, including certain minimum aggregate revenue requirements. The Company was in compliance with these covenants at December 31, 2014 and March 31, 2015.

The SWK Credit Agreement includes customary events of default, including failure to pay principal, interest or fees when due, failure to comply with covenants, default under certain other indebtedness, certain insolvency or bankruptcy events, the occurrence of certain material judgments, the institution of any proceeding by a government agency or a change of control of the Company that is not otherwise permitted under the SWK Credit Agreement.

Refer to Note 11 to these unaudited condensed consolidated financial statements for a description of the second amendment to the SWK Credit Agreement, dated April 3, 2015, pursuant to which the Company drew the remaining $2,000,000 of the Loan Commitment Amount and issued certain of the Lenders warrants to purchase an aggregate of 2,702,702 shares of Common Stock.

Income Taxes

Deferred tax assets and liabilities are determined based on differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.

ASC 740, Income Taxes, clarifies the accounting for uncertainty in income taxes recognized in financial statements and requires the impact of a tax position to be recognized in the financial statements if that position is more likely than not of being sustained by the taxing authority. As of December 31, 2014 and March 31, 2015, the Company does not have a liability for unrecognized tax benefits. The Company recognizes interest and penalties associated with tax matters as part of the income tax provision, and includes accrued interest and penalties with the related tax liability in the balance sheet. For the periods ended March 31, 2014 and 2015, there were no interest and penalties recorded in the Condensed Consolidated Statement of Operations.

Stock-Based Compensation

The Company accounts for stock-based compensation in accordance with ASC 718, Stock Compensation, Share-Based Payment. Stock-based compensation expense for all stock-based compensation awards granted is based on the grant-date fair value estimated in accordance with the provisions of ASC 718. The Company recognizes these compensation costs on a straight-line basis over the requisite service period of the award, which is generally the option vesting period. As further described in Note 7, certain awards granted to Thomas A. Bologna, the Company’s Chairman and Chief Executive Officer, were recognized based on an accelerated vesting basis triggered by market conditions rather than a straight-line basis.

The Company accounts for equity instruments issued to non-employees in accordance with ASC 505, Equity. Under ASC 505, stock option awards issued to non-employees are measured at fair value using the Black-Scholes option-pricing model and recognized pursuant to a performance model.

Management Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates in these condensed consolidated financial statements have been made for revenue, allowances for doubtful accounts, impairment of long-lived assets, depreciation of property and equipment and stock-based compensation. Actual results could differ materially from those estimates.

Long-lived Assets

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company evaluates potential impairment by comparing the carrying amount of the asset with the estimated undiscounted future cash flows associated with the use of the asset and its eventual disposition. Should the review indicate that the assets cost is not recoverable, the carrying value of the asset would be reduced to its fair value, which is measured by future discounted cash flows.

Foreign Currency Translation

The financial position and results of operations of the Company’s foreign subsidiary are determined using local currency as the functional currency. Assets and liabilities of these operations are translated at the exchange rate in effect at each period-end. Statement of Operations amounts are translated at the average rate of exchange prevailing during the period. Translation adjustments arising from the use of differing exchange rates from period to period are included in accumulated other comprehensive loss in stockholders’ deficit.

Comprehensive Loss

The components of comprehensive loss are accumulated net loss and foreign currency translation adjustments for the three months ended March 31, 2014 and 2015.

Fair Value of Financial Instruments

Cash and cash equivalents are stated at cost, which approximates fair market value.  Cash equivalents consist of money market accounts, with fair values estimated based on quoted market prices. Debt balances are stated at historical amounts less principal payments, which approximate fair market value. The Company believes interest rates in its debt agreements are commensurate with lender risk profiles for similar companies.

Advertising Costs

The Company markets its services through its advertising activities in trade publications and on the internet. Advertising costs are included in selling and marketing expenses on the statements of operations and are expensed as incurred. Advertising costs for the three months ended March 31, 2014 and 2015 were $6,422 and $17,124, respectively.

Concentration of Credit Risk and Clients and Limited Suppliers

Cash and cash equivalents are maintained at financial institutions and, at times, balances may exceed federally insured limits. The Company has never experienced any losses related to these balances. At March 31, 2015, the Company had $1,476,222 in cash and cash equivalents that exceeded federally insured limits. At March 31, 2015, $7,803 of cash was held outside of the United States.

Many of the supplies and reagents used in the Company’s testing process are procured from a limited number of suppliers. Any supply interruption or an increase in demand beyond the suppliers’ capabilities could have an adverse impact on the Company’s business. Management believes it can identify alternative sources, if necessary, but it is possible such sources may not be identified in sufficient time to avoid an adverse impact on its business. The Company purchases certain laboratory supplies and reagents primarily from a limited number of suppliers. The Company made approximately 73% of its reagent purchases from four suppliers during the year ended December 31, 2014 and made approximately 70% of its reagent purchases from three suppliers during the three months ended March 31, 2015.

Recent Accounting Pronouncements

In April 2015, the Financial Accounting Standards Board issued ASU 2015-03 “Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” ASU 2015-03 requires an entity to present debt issuance costs related to a recognized debt liability in the balance sheet as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this update. The amendment will be effective for the Company’s annual and interim reporting periods beginning January 1, 2016 and should be applied on a retrospective basis. The adoption of ASU 2015-03 will not have any impact on the Company’s results of operations, but will result in debt issuance costs being presented as a direct reduction from the carrying amount of debt liabilities.  This standard will not have a material impact on the Company’s consolidated financial statements.

In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which modifies how all entities recognize revenue, and consolidates into one Accounting Standards Codification ("ASC") Topic (ASC Topic 606, Revenue from Contracts with Customers) the current guidance found in ASC Topic 605, Revenue Recognition, and various other revenue accounting standards for specialized transactions and industries. The core principle of the guidance is that “an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” In achieving this objective, an entity must perform five steps: (1) identify the contract(s) with a customer, (2) identify the performance obligations of the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 also clarifies how an entity should account for costs of obtaining or fulfilling a contract in a new ASC Subtopic 340-40, Other Assets and Deferred Costs – Contracts with Customers.

ASU 2014-09 is effective for public companies for annual periods beginning after December 15, 2016 and interim periods within those annual periods, and early adoption is not permitted. ASU 2014-09 may be applied using either a full retrospective approach, in which all years included in the financial statements are presented under the revised guidance, or a modified retrospective approach. Under the modified retrospective cumulative catch-up approach, financial statements will be prepared using the new standard for the year of adoption, but not for prior years. Under this method, entities will recognize a cumulative catch-up adjustment to the opening balance of retained earnings at the effective date for contracts that still require performance by the Company and disclose all line items in the year of adoption as if they were prepared under the old revenue guidance. The Company is currently evaluating the impact of ASC 606, but at the current time does not know what impact the new standard will have on revenue recognized and other accounting decisions in future periods, if any, nor what method of adoption will be selected if the impact is material.

In August 2014, the Financial Accounting Standards Board issued ASU No. 2014-15, Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU 2014-09”). ASU 2014-15 provides guidance on management's responsibility in evaluating whether there is substantial doubt about a company's ability to continue as a going concern and about related footnote disclosures. For each reporting period, management will be required to evaluate whether there are conditions or events that raise substantial doubt about a company's ability to continue as a going concern within one year from the date the financial statements are issued. ASU 2014-15 is effective for annual periods ending after December 15, 2016, and interim periods thereafter; earlier adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial condition, results of operations or cash flows.

4. Loss Per Share

The Company calculates net loss per share in accordance with ASC 260, Earnings Per Share. Under the provisions of ASC 260, basic net loss per share is computed by dividing the net loss for the period by the weighted average number of shares of common stock outstanding for the period. Diluted net loss per share is computed by dividing the net loss by the weighted average number of shares of common stock and dilutive common stock equivalents then outstanding. Common stock equivalents consist of shares of common stock issuable upon the exercise of stock options and warrants.

The following table sets forth the computation for basic and diluted loss per share:

	Three Months Ended March 31,
	2014			2015
Numerator:
Net loss	$	(3,504,439	)	$	(4,018,380	)

Outstanding stock options to purchase 2,217,134 and 2,461,078 shares of common stock of the Company for the periods ended March 31, 2014 and 2015, respectively, were excluded from the calculation of diluted loss per share as their effect would have been antidilutive. Also excluded from the calculation were 270,000 unvested shares of restricted common stock for both of the periods ended March 31, 2014 and 2015. Outstanding warrants to purchase 1,258,013 shares of common stock of the Company for the period ended March 31, 2015 were also excluded in the calculation of diluted loss per share.

5. Commitments and Contingencies – (continued)

Guarantees

The Company enters into indemnification provisions under its agreements with other counterparties in its ordinary course of business, typically with business partners, clients and landlords. Under these provisions, the Company generally indemnifies and holds harmless the indemnified party for losses suffered or incurred by the indemnified party as a result of the Company's activities. These indemnification provisions generally survive termination of the underlying agreement. The Company reviews its exposure under these agreements no less than annually, or more frequently when events require. The Company believes the estimated fair value of these agreements is minimal as, historically, no payments have been made by the Company under these indemnification obligations. Accordingly, the Company has no liabilities recorded for these agreements as of December 31, 2014 and March 31, 2015.

Legal Matters

The Company is, from time to time, involved in legal proceedings, regulatory actions, claims and litigation arising in the ordinary course of business. Reserves are established for specific liabilities in connection with legal actions when they can be deemed probable and estimable. These matters are not expected to have a material adverse effect upon the Company’s financial condition.

Employment Agreements

The Company has employment contracts with several individuals, which provide for annual base salaries and potential bonuses. These contracts contain certain change of control, termination and severance clauses that require the Company to make payments to certain of these employees if certain events occur as defined in their respective contracts.

6. License and Collaborative Agreements

License Agreement with the University of Southern California (“USC”)

In April 2000, as amended in June 2002 and April 2005, the Company entered into a license agreement with USC. Under this agreement, USC granted the Company a worldwide, exclusive license with the right to sublicense, the patents for nucleic acid extraction methodologies (“RGI-1”) and related technology, for use in human and veterinary diagnostic laboratory services, the sale of clinical diagnostic products, and the sale of research products to the research community. USC retains the right under the agreement to use the technology for research and educational purposes.

In consideration for this license, the Company agreed to pay USC royalties based on a percentage of net sales of products or services that make use of RGI-1 and related technology and to meet a certain minimum in royalty payments. Royalty expense relating to this agreement amounted to $10,961 and $5,508 for the three months ended March 31, 2014 and 2015, respectively. Changes to estimates of factors impacting the accrued royalty liability could result in adjustments in future periods. Such expense is included in cost of revenue in the accompanying unaudited consolidated statements of operations.

License Agreement with Roche Molecular Systems (“Roche”)

In November 2004, the Company entered into a non-exclusive license to use Roche’s technology including specified nucleic acid amplification processes (“PCR Processes”) to perform certain human invitro clinical laboratory services. In consideration for this license, the Company is obligated to pay royalties to Roche, based on a percentage of net sales of products or services that make use of the PCR Processes. Royalty expense included in cost of revenue relating to this agreement amounted to $44,373 and $16,265 for the three months ended March 31, 2014 and 2015, respectively.

In November 2004, the Company also entered into an agreement with Roche, pursuant to which the Company is collaborating with Roche to produce commercially viable assays used in the validation of genetic markers for pharmaceutical companies. Specifically, the Company has licensed the rights to Roche to use the pre-diagnostic assays the Company develops in the course of using its RNA-extraction technologies to provide testing services to pharmaceutical companies and to produce diagnostic kits that then can be sold commercially to those pharmaceutical companies. Roche is required to pay the Company royalties of a certain percentage of net sales of such diagnostic kits sold to pharmaceutical companies. Through March 31, 2015, Roche has not been required to pay any royalties to the Company pursuant to this agreement.

In January 2006, the Company entered into a master services agreement with GSK, a leading pharmaceutical manufacturer, pursuant to which the Company provides services in connection with profiling the expression of various genes from a range of human cancers. Under the agreement, the Company provides GSK with testing services as described in individual protocols and GSK pays the Company for such services based on the pricing schedule established for each particular protocol. GSK was obligated to make minimum annual payments to the Company under the agreement and also was obligated to make a non-refundable upfront payment to the Company, to be credited against work undertaken pursuant to the agreement.

In December 2008, the Company amended and restated its master services agreement with GSK and extended the term of the agreement for a two-year period, with the option for the parties to extend the agreement for additional one-year periods at the end of the term, upon their mutual written agreement. In addition, the Company became a preferred provider to GSK and its affiliates of genetic testing services on a fee-for-service basis and, in anticipation of the services to be provided, GSK agreed to make a non-refundable upfront payment.

The Company recognized revenue of $-0- and $2,046 relating to the GSK agreement for the three months ended March 31, 2014 and 2015, respectively.

Master Services Agreement with GlaxoSmithKline Biologicals S.A. (“GSK Bio”)

On July 26, 2012, the Company entered into a second amended and restated master services agreement with GSK Bio, the vaccine division of GSK. The agreement, which was effective as of May 15, 2012, was amended on December 17, 2014 to extend the term to December 31, 2015. Pursuant to this agreement, as amended, the Company provides testing services for clinical trials and epidemiology studies relating to GSK Bio’s cancer immunotherapies. The Company performs these testing services on a fee-for-service basis as embodied in written task orders. GSK Bio retains the intellectual property rights to inventions, improvements and data resulting from the services performed under the agreement. The Company retains all intellectual property rights to its testing services and proprietary processes. All intellectual property owned by either party on the date of the agreement remains the exclusive property of the owning party.

The agreement will provides that any outstanding task orders at the time of termination will not thereby terminate (unless otherwise agreed in writing by the parties), and any such task orders will continue for the respective terms specified in such task orders (and the parties shall continue to perform their obligations thereunder). GSK Bio may terminate the agreement, without cause, upon 90 days’ written notice to the Company. The Company may terminate the agreement, without cause, upon one year’s written notice to GSK Bio. The agreement may also be terminated early if either party enters bankruptcy or similar proceedings or in the event of a material breach. GSK Bio may terminate the agreement immediately if the Company experiences a “change of control,” as defined in the agreement.

The agreement also provides for mutual indemnification by the parties and contains customary representations, warranties and covenants, including covenants governing the parties’ use of confidential information and representations regarding adequate insurance coverage or self-insurance.

The Company recognized revenue of $328,281 and $341,462 relating to the services performed for GSK Bio for the three months ended March 31, 2014 and 2015, respectively.

7. Stock Options, Restricted Stock and Warrants

In March 2000, the Company adopted a Stock Option Plan (the “2000 Stock Plan”) as approved by its Board of Directors. Under the 2000 Stock Plan, the Company granted options to acquire up to 1,600,000 shares of common stock. In connection with the adoption of the 2006 Employee, Director and Consultant Stock Plan, as further discussed below, the Company is to grant no additional options under the 2000 Stock Plan. Under the 2000 Stock Plan, there were no options to purchase shares of the Company’s common stock that remained outstanding as of December 31, 2013. Prior to March 2007, the Company also granted options to purchase 16,000 shares of common stock to two consultants which were granted under separate agreements outside of the 2000 Stock Plan.

On October 26, 2006, the Board of Directors of the Company approved, and on May 1, 2007, reapproved the adoption of the 2006 Employee, Director and Consultant Stock Plan (the “2006 Stock Plan”). The stockholders approved the 2006 Stock Plan on June 1, 2007. The initial number of shares which may be issued from time to time pursuant to the 2006 Stock Plan was 2,160,000 shares of common stock. Also, the 2006 Stock Plan includes the number of shares subject to purchase under options issued under the 2000 Stock Plan, where the options expired on or after October 18, 2006, subject to a maximum of 210,000 additional options.  In addition, on the first day of each fiscal year of the Company during the period beginning in fiscal year 2008 and ending on the second day of fiscal year 2017, the number of shares that may be issued from time to time pursuant to the 2006 Stock Plan is increased by the lesser of (i) 200,000 shares or equivalent, after determination of the effect of any stock split, stock dividend, combination or similar transactions as set forth in the 2006 Stock Plan, (ii) 5% of the number of outstanding shares of common stock of the Company on such date or (iii) an amount determined by the Board of Directors of the Company.  The initial number of shares available for issuance of 2,160,000 increased by 210,000 for options issued under the 2000 Stock Plan expiring after October 2006 and by 200,000 in 2008 through 2015, resulting in the total number of shares that may be issued as of January 1, 2015 to be 3,970,000. As of March 31, 2015, there were 1,508,922 options available for grant under the 2006 Stock Plan.

Employee options vest according to the terms of the specific grant and expire 10 years from the date of grant. Non-employee option grants to date typically vest over a two- to three-year period. The Company had 2,461,078 options outstanding at a weighted average exercise price of $1.59 at March 31, 2015. There were 1,027,992 non-vested stock options outstanding with a weighted average exercise price of $1.07 at March 31, 2015. As of March 31, 2015, there was $637,950 of total unrecognized compensation cost related to non-vested share-based compensation arrangements granted under the 2006 Stock Plan. That cost is expected to be recognized over a weighted-average period of 2.4 years.

Except for certain grants of restricted common stock and common stock options containing market conditions as described below, the Company estimated share-based compensation expense for the three months ended March 31, 2015* using the Black-Scholes model with the following weighted average assumptions:

	Three Months Ended March 31, 2015
Risk free interest rate		1.68	%
Expected dividend yield		—	%
Expected volatility		99.2	%
Expected term **(in years)		6.25
Forfeiture rate ***		7.0	%

*     There were no stock options issued for the three months ended March 31, 2014.

**   Expected term is calculated using SAB 107, Simplified Formula. Management has concluded that the use of the simplified method for calculating the expected term of its common stock option grants is appropriate given the lack of historical exercises and the standard terms of the employee option grants, including, options are granted at-the-money, exercise is conditional only on performing service through the vesting dates, termination of service causes forfeiture of options, employees have a limited number of days to exercise options after termination of service, and options are non-transferable.

*** Forfeiture range represents 0% for directors and 21% for employees.

The following table summarizes the stock option activity for the 2006 Plan for the three months ended March 31, 2015:

	Number of Shares			Weighted Average Exercise Price		Remaining Contractual Life (Years)		Aggregate Intrinsic Value

Exercisable, March 31, 2015 (Unaudited)		1,433,086		$	1.91		7.0	$	—

The weighted-average grant-date fair value of options granted during the year ended December 31, 2014 was $0.70. The weighted-average grant-date fair value of options granted during the three months ended March 31, 2015 was $0.43. The aggregate intrinsic value of outstanding options at December 31, 2014 and the options exercised during 2014 were $-0- and $7,605, respectively, which represents options whose exercise price was less than the closing fair market value of the Company’s common stock on December 31, 2014 of $0.32. No options were exercised during the three months ended March 31, 2015.

8. Income Taxes

Deferred income taxes result from temporary differences between income tax and financial reporting computed at the effective income tax rate. The Company has established a valuation allowance against its net deferred tax asset due to the uncertainty surrounding the realization of such asset. Management periodically evaluates the recoverability of the deferred tax assets. At such time it is determined that it is more likely than not that deferred tax assets are realizable, the valuation allowance will be reduced.

The Company files U.S. federal, U.S. state, and foreign tax returns. The Company’s major tax jurisdictions are U.S. federal and the State of California. The Company is subject to tax examinations for the open years from 2004 through 2014.

10. Fair Value Measurements

ASC 820, Fair Value Measurements and Disclosures, defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. ASC 820 provides guidance on how to measure fair value by providing a fair value hierarchy used to classify the source of the information. ASC 820 establishes a three-level valuation hierarchy of valuation techniques that is based on observable and unobservable inputs. Classification within the hierarchy is determined based on the lowest level of input that is significant to the fair value measurement. The first two inputs are considered observable and the last unobservable, that may be used to measure fair value and include the following:

Level 1 - Quoted prices in active markets for identical assets or liabilities.

Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

As of December 31, 2014 and March 31, 2015, the Company did not hold any assets that are required to be measured at fair value on a recurring basis.

11. Subsequent Events

Second Amendment to the SWK Credit Agreement

On April 3, 2015 (the “Second Amendment Closing Date”), the Company entered into a second amendment (the “Second Amendment”) to the SWK Credit Agreement.  Pursuant to the Second Amendment, the Company drew the remaining $2,000,000 of the Loan Commitment Amount, thereby increasing the total amount advanced to the Company under the SWK Credit Agreement to $12,000,000. The maturity date for the term loan under the SWK Credit Agreement remains July 30, 2020, or such earlier date on which the Loan Commitment Amount is terminated, pursuant to the terms of the SWK Credit Agreement.

In addition, on the Second Amendment Closing Date, the Company issued warrants to purchase an aggregate of 2,702,702 shares of Common Stock (the “Second Amendment Warrants”) to the Lenders advancing the term loan to the Company on the Second Amendment Closing Date.  The Second Amendment Warrants are exercisable up to and including April 3, 2021 at an exercise price of $0.37 per share, subject to adjustment.  A Lender may exercise its Second Amendment Warrant on a cashless basis at any time.  In the event a Lender exercises its Second Amendment Warrants on a cashless basis, the Company will not receive any proceeds.  The exercise price of the Second Amendment Warrants is subject to customary adjustments for stock splits, stock dividends, recapitalizations and the like.

Overview

Response Genetics, Inc. (the “Company”) was incorporated in the State of Delaware on September 23, 1999 as Bio Type, Inc. for the purpose of providing molecular profiling services of tumor tissue that has been formalin-fixed and embedded in paraffin. In August 2000, we changed our name to Response Genetics, Inc.

Our Approach

Clinical studies have shown that not all cancer therapy works effectively in every patient, and that a number of patients receive therapy that has no benefit to them and may potentially even be harmful. Our goal is to provide cancer patients and their physicians with a means to make informed, individualized treatment decisions based on genetic analysis of tumor tissues. We are focusing our efforts in the following areas:

• Continued commercialization of our ResponseDX^® tests, including the ResponseDX: Tissue of Origin^® test, formerly offered by Pathwork Diagnostics, that we acquired when we purchased substantially all of the assets of Pathwork Diagnostics in August 2013. We began selling the ResponseDX: Tissue of Origin^® test in February 2014. 

• Enhancing our capabilities in the way we deliver our services to oncologists and pathologists. In late 2013, the Company introduced its TC/PC system to competitively offer its services to pathologists;

• Developing additional diagnostic tests for assessing the risk of cancer recurrence, prediction to therapy response and tumor classification in cancer patients;

• Expanding our testing services business by pursuing new technologies through collaborations and in-licensing to expand our business;

• Entered into an exclusive agreement with Knight Diagnostic Laboratories at Oregon Health & Science University for a proprietary next generation sequencing panel for lung cancer; and

• Selectively building our pharmaceutical services business.

Our technologies enable us to reliably and consistently extract the nucleic acids ribonucleic acid (“RNA”) and deoxyribonucleic acid (“DNA”) from tumor specimens that are stored as formalin-fixed and paraffin-embedded (“FFPE”), specimens and thereby to analyze genetic information contained in these tissues. This is significant because the majority of patients diagnosed with cancer have a tumor biopsy sample stored in paraffin, while only a small percentage of patients’ tumor specimens are frozen. Our technologies also enable us to use the FFPE patient biopsies for the development of diagnostic tests. 

20

ResponseDX^®

The outcome of cancer therapy is highly variable due to genetic differences among the tumors in cancer patients. Some patients respond well with tumor shrinkage and increase in life span. Other patients do not obtain benefit from the same therapy and may actually experience toxic side effects, psychological trauma and delay in effective treatment.

Until recently, most cancer treatment regimens were administered without any pre-selection of patients on the basis of the particular genetics of their tumor. However, advances in molecular technologies have enabled researchers to identify and measure genetic factors in patients’ tumors that may predict the probability of success or failure of many anti-cancer agents. In order to increase the chances of a better outcome for cancer patients, we offer and continue to expand our offering of tests for measuring predictive factors for therapy response in tumor tissue samples. We provide tests for non-small cell lung cancer (“NSCLC”), colorectal cancer (“CRC”), gastric and gastroesophageal cancer (“GE”), melanoma, thyroid cancer, breast cancer and glioma through our ResponseDX: Lung^®, ResponseDX: Colon^®, ResponseDX: Gastric^®, ResponseDX: Melanoma^®, ResponseDX: Thyroid^TM, ResponseDX: Breast^TM and ResponseDX^® Glioma test suites at our laboratory located in Los Angeles, California, which is certified under the Clinical Laboratory Improvement Amendments of 1988 (“CLIA”). These tests serve to help oncologists make optimal therapeutic decisions for cancer patients. The results from our tests may help oncologists choose among therapies to treat their cancer patients.

Response DX: Tissue of Origin^® Test

In August 2013, the Company acquired substantially all of the assets of Pathwork Diagnostics, Inc. including its FDA-cleared Tissue of Origin cancer test. This newly acquired test was launched commercially by the Company in February 2014 as the ResponseDX: Tissue of Origin^® test. The ResponseDX: Tissue of Origin^® test is a microarray-based gene expression test that aids in identifying challenging tumors, including metastatic, poorly differentiated, and undifferentiated cancers. The ResponseDX: Tissue of Origin^® test uses a proprietary microarray platform and proprietary software to compare the expression of 2,000 genes in a patient's tumor with a panel of 15 known tumor types that represent 90% of all known cancers. The test received FDA clearance in June 2010.

As of March 31, 2015, our ResponseDX^® sales team consisted of 17 members located in the West, Southeast, and Northeast areas of the United States.

Expansion of our ResponseDX^® diagnostic test panels

Our research and development activities primarily relate to the development and validation of diagnostic tests in connection with our ResponseDX^® diagnostic services. In 2014, we added the ResponseDX^®: Glioma profile and the ResponseDX: Tissue of Origin^® test to our product offering and we anticipate continuing to add additional tests in our existing panels.

Addition of Next-Generation Sequencing to our suite of technologies

The Company is utilizing mutational analysis by next-generation sequencing (“NGS”) to complement our suite of molecular diagnostics platforms for the analysis of cancer specimens. The Company is using NGS to detect genomic changes from FFPE tissue samples and to provide physicians with reports that are comprehensive with respect to clinically actionable alterations. To this end, on April 15, 2014, the Company entered into an agreement with Knight Diagnostic Laboratories of the Oregon Health and Science University (“OHSU”) to offer OHSU’s proprietary next generation sequencing panel which provides full gene sequencing of the actionable genes for lung cancer rather than detection only of so-called hot spots as part of the Company’s testing menu, as well as other NGS panels. The collaboration leverages the Company’s national sales force.

Pursue Additional Collaborations and In-Licensing to Expand Our Business

We intend to pursue additional collaborations with pharmaceutical companies or in-licensing of products or technologies that will enable us to accelerate the implementation of our plans to expand the services we provide to oncologists and pathologists. We expect to implement this plan by way of licensing of technology and know-how, agreements with other companies, strategic collaborations, and other similar transactions. We expect these collaborations to provide us with early access to new technologies available for commercialization.

There are no assurances that we will be able to continue making our current ResponseDX^® tests available, or make additional ResponseDX^® tests available; or that we will be able to develop and commercialize tests of other types of cancer; or that we will be able to expand our testing service business through collaborations or in-licensing of products or technologies.

Research and development is an important part of the Company’s development as we seek to expand our series of diagnostic tests for cancer patients. Our research and development expenses represented 9.5% and 5.2% of our total operating expenses for the three months ended March 31, 2014 and 2015, respectively. Major components of the $467,567 and $268,200 in research and development expenses for the three months ended March 31, 2014 and 2015, respectively, included personnel costs, supplies and reagents for our research activities, sample procurement costs and patent fees. We expect research and development expenses to continue as we work to develop additional aspects of our technology and to study diagnostic indicators for various forms of cancer.

21

Providing Accurate and High Quality Results - Quality Assurance Program

The quality of our diagnostic testing services is important to us and our clients. In order to deliver accurate and high quality results, we have established a quality management system in compliance with regulations and standards such as those set by the College of American Pathologists (“CAP”), the Clinical Laboratory Improvement Amendments of 1988 (“CLIA”), Good Clinical Laboratory Practices (“GCLP”), and Good Laboratory Practice (“GLP”) for our laboratory operations. This program is designed to utilize both external and internal resources to monitor the quality of our laboratory operations. For example, we participate in external quality surveillance programs, including ongoing proficiency testing programs administered CAP. CAP is an independent, non-governmental organization of board-certified pathologists which accredits, on a voluntary basis, laboratories. CAP has been deemed by the Centers for Medicare and Medicaid Services (“CMS”), which is charged with administering CLIA, as an accrediting agency to inspect clinical laboratories to determine adherence to the standards of CLIA. Our most recent CAP inspection was successfully completed in October of 2014. 

In addition, the Company received approval from the New York State Department of Health to offer, market and report results of the Company's ResponseDX^® tests to healthcare providers in the State of New York. New York is the only U.S. state that requires an independent regulatory review process including clinical and technical evaluation for laboratory developed tests. It conducts one of the most demanding investigations including validation of laboratory developed tests and an on-site inspection of each laboratory seeking a New York State clinical laboratory permit. The State's review of the Company was completed after the Company met all of the State's regulatory requirements including a two-day inspection of the Company's CLIA certified laboratory on September 23rd and 24th of 2014.

Critical Accounting Policies and Significant Judgments and Estimates

This discussion and analysis of our financial condition and results of operations is based on our condensed consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as revenues and expenses during the reporting periods. We evaluate our estimates and judgments on an ongoing basis. We base our estimates on historical experience and on various other factors we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results could therefore differ materially from those estimates under different assumptions or conditions. We believe the following critical accounting policies reflect our more significant estimates and assumptions used in the preparation of our financial statements.

Revenue Recognition

Pharmaceutical Revenue

Revenues that are derived from pharmacogenomic testing services provided to pharmaceutical companies are recognized on a contract specific basis pursuant to the terms of the related agreements. Revenue is recognized in accordance with ASC 605, Revenue Recognition, which requires that four basic criteria 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 client or services have been rendered; (3) the price is fixed or determinable; and (4) collectability is reasonably assured.

Revenues are recorded on an accrual basis as the contractual obligations are completed and as a set of assays is processed through the Company’s laboratory under a specified contractual protocol and are recorded on the date the tests are completed. Certain contracts have minimum assay requirements that, if not met, result in payments that are due upon the completion of the designated period. In these cases, revenues are recognized when the end of the specified contract period is reached.

ResponseDX^® Revenue

Net revenue for the Company’s diagnostic services is recognized on an accrual basis at the time diagnostic tests are completed. Each test performed relates to a specimen encounter derived from a patient, and received by the Company on a specific date (such encounter is commonly referred to as an “accession”). The Company’s services are billed to various payors, including Medicare, private health insurance companies, healthcare institutions, and patients. The Company reports net revenue from contracted payors, including certain private health insurance companies, and healthcare institutions based on the contracted rate, or in certain instances, the Company’s estimate of the amount expected to be collected for the services provided. For billing to Medicare, the Company uses the published fee schedules, net of standard discounts (commonly referred to as “contractual allowances”). The Company reports net revenue from non-contracted payors, including certain private health insurance companies, based on the amount expected to be collected for the services provided. The Company analyzes historical payments from payors as a percentage of amounts billed by the Company to estimate the amount expected to be collected for the services provided for purposes of recording net revenue.

The Company has its Medicare provider number which allows it to invoice and collect from Medicare. Invoicing to Medicare is primarily based on amounts allowed by Medicare for the service provided as defined by Common Procedural Terminology (“CPT”) codes. In January 2013, the initial 2013 annual Medicare fee schedule update was announced which included proposed changes to Medicare reimbursement rates that significantly reduced the reimbursement rates for certain of the testing services we provide. In addition, on July 8, 2013, the Centers for Medicare and Medicaid Services (“CMS”) released a proposed rule for 2014 entitled “Medicare Program; Revisions to Payment Policies under the Physician Fee Schedule, Clinical Laboratory Fee Schedule & Other Revisions to Part B for CY 2014” that contained a number of provisions that adversely impacted the level of reimbursement for a variety of tests for which the Company receives reimbursement from Medicare. The Company participated with other impacted organizations to provide guidance to the local Medicare Administrative Contractor (“MAC”) that resulted in the local MAC updating certain pricing through September 2013 which reflected an increase in many of the tests originally priced in January 2013. In addition, on October 1, 2013, CMS issued updated payment rates which reflected an increase in reimbursement amount and positive coverage determination for some, but not all, of the CPT codes used by the Company.

22

Primarily as a result of these CPT code changes, Medicare price changes, and the resulting confusion and erratic payment experience in the payor community in 2013 and 2014, as well as the resulting necessity to acquire new skills in collections, we have experienced a departure from our normal reimbursement patterns with Medicare and other payors. Specifically, we have experienced delays in certain reimbursements for services and an increase in initial denials of claims for certain services provided. Accordingly, we re-evaluated the assumptions employed in our model for estimating revenue to be recognized for ResponseDX^® testing. We view the code and price changes described above as affecting only the assumptions we used in pricing our services. The nature of the testing we provide, the evidence we gather to establish the creditworthiness of our payors and the delivery method of our services have not changed from prior periods, and there are no indicators that these assumptions require change. We have also restructured and overhauled our billing department in late 2014/early 2015 and have already seen a significant increase in our collections related to our ResponseDX sales.  We expect to continue to see improvements throughout 2015 and beyond from these efforts.  We have engaged a seasoned billing/reimbursement expert on a consulting basis to assist with this overhaul and restructuring effort.

We performed analyses that considered our historical patterns of revenue by payor in conjunction with the fluctuations we experienced in the three months ended March 31, 2015 and twelve months ended December 31, 2014 to arrive at the revenue recorded during those periods.

On November 13, 2014, CMS published CMS-1612-FC, a new final rule with comment period (the “Final Rule”) entitled “Medicare Program; Revisions to Payment Policies under the Physician Fee Schedule, Clinical Laboratory Fee Schedule, Access to Identifiable Data for the Center for Medicare and Medicaid Innovation Models & Other Revisions to Part B for CY 2015”. The Final Rule, which was initially proposed on July 3, 2014, contains a number of provisions including new and modified CPT codes that may adversely impact the level of reimbursement for certain tests offered by the Company, including fluorescent in-situ hybridization (“FISH”) tests for which the Company receives reimbursement from the Medicare program. The Final Rule established lower relative value units (“RVU’s”) for FISH testing which lower valuation led to a 16-20% reduction in multiplex FISH reimbursement in 2015 after taking into account the NCCI changes from 2014 discussed below. Reimbursement for less frequent single-probe FISH testing was reduced by 45-50%. The Final Rule was subject to a 60-day comment period which ended on December 30, 2014. Impacted organizations similarly situated as the Company have provided guidance to the local Medicare MAC. It is uncertain if the guidance provided to Medicare and the local MAC by impacted organizations will result in fee increases or additional positive coverage determinations in 2015. If, however, the current level of reduction in reimbursement rates is adopted as is, it may adversely impact our reimbursement from Medicare for FISH.

Additionally, CMS has as part of its regulatory structure developed the National Correct Coding Initiative (“NCCI”) which is intended to promote national correct coding methodologies and to control improper coding leading to inappropriate payment in Medicare Part B claims. In December 2013, the NCCI Coding Policy Manual changed the billing requirement for FISH testing. The change relates to what NCCI considers “bundled” services and limits the allowable quantity of certain tests that are billed for FISH testing. This impacts us by limiting the number of units we may bill for certain test codes which lowers the overall reimbursement we receive for FISH tests. There can be no assurance that CMS will make any modifications in the existing language of the NCCI. Effective on January 1, 2015 the AMA adopted all of the NCCI definitions for FISH which, if adopted, may adversely impact our reimbursement from commercial insurance plans going forward.

A number of proposals for legislation or regulation continue to be under discussion which could have the effect of substantially reducing Medicare reimbursements for clinical laboratories or introducing cost sharing to beneficiaries. Depending upon the nature of regulatory action, if any, which is taken and the content of legislation, if any, which is adopted, the Company could experience a significant decrease in revenues from Medicare and Medicaid, which could have a material adverse effect on the Company. The Company is unable to predict, however, the extent to which such actions will be taken.

License Fees

We have licensed technology for the extraction of RNA and DNA from FFPE tumor specimens from the University of Southern California (“USC”) in exchange for royalty fees on revenue generated by use of this technology. These royalties are calculated as a fixed percentage of net sales price as defined in the agreement that we generate from use of the technology licensed from USC. Total license fees expensed in cost of revenue under the royalty agreement with USC were $10,961 and $5,508 for the three months ended March 31, 2014 and 2015, respectively. Such expense is included in our cost of revenue. We also maintain a non-exclusive license to use Roche Molecular Systems, Inc.’s (“Roche”) polymerase chain reaction (“PCR”), homogenous PCR, and reverse transcription PCR processes. We pay Roche a royalty fee based on revenue that we generate through use of this technology. Royalties expensed in cost of revenue under this agreement totaled $44,373 and $16,265 for the three months ended March 31, 2014 and 2015, respectively. Changes to estimates of factors impacting the accrued royalty liability could result in adjustments in future periods.

We are subject to potentially significant variations in royalties recorded in any period. While the amount paid is based on a fixed percentage of net sales price as defined in the agreement of specific tests pursuant to terms set forth in the agreements with USC and Roche, the amount due is calculated based on the revenue we recognize using the respective licensed technology. As discussed above, this revenue can vary from period to period as it is dependent on the timing of the specimens submitted by our clients for testing.

Additionally, the Company periodically analyzes the technical procedures performed in its test offerings to assess which activities utilize licensed technologies and to calculate royalties for use of the licensed technology. The most recent analyses indicate that the Company could owe less than the amounts that have been accrued for royalties payable. Roche is still reviewing the Company’s updated royalty calculations. It is possible that based on Roche’s review and the Company’s discussions with Roche, the Company may further adjust its Roche royalty accrual.

Cost of Revenue

Cost of revenue represents the cost of materials, direct labor, royalties, costs associated with processing tissue specimens including pathological review, staining, microdissection, paraffin extraction, reverse transcription polymerase chain reaction, FISH, quality control analyses, license fees and delivery charges necessary to render an individualized test result. Costs associated with performing tests are recorded as the tests are processed.

Accounts Receivable and Allowance for Doubtful Accounts

Pharmaceutical Accounts Receivable and Allowance for Doubtful Accounts

We invoice our pharmaceutical clients as specimens are processed and any other contractual obligations are met. Our contracts with pharmaceutical clients typically require payment within 45 days of the date of invoice. We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our clients to make required payments. We specifically analyze accounts receivable and historical bad debts, client credit, current economic trends and changes in client payment trends when evaluating the adequacy of the allowance for doubtful accounts. Account balances are charged-off against the allowance when it is probable the receivable will not be recovered. Bad debts to date related to our pharmaceutical customers have been minimal and there is no allowance for doubtful accounts for our pharmaceutical revenue at March 31, 2015 and December 30, 2014.

Response DX^® Accounts Receivable and Allowance for Doubtful Accounts

Revenue is recognized for services rendered when the testing process is completed and test results are reported to the ordering physician. We bill Medicare and private payors (“Private Payors”) for ResponseDX ® upon completion of the required testing services. As such, we take assignment of benefits and the risk of collection with Medicare and Private Payors. We continue to monitor the collection history for Medicare and Private Payors. We have a process to estimate and review the collectability of our aged receivables based on the period of time they have been outstanding. Based on the historical experience for our Medicare and Private Payor accounts and a detailed analysis of the same, we have determined, that accounts receivable associated with certain billings are unlikely to be collected. At March 31, 2015 and December 31, 2014 the Company continues to reserve 100% against its Medicare accounts receivable aged greater than one year. Therefore, we have recorded an allowance for doubtful accounts of $2,226,890 and $2,071,706 as March 31, 2015 and December 31, 2014, respectively. The Company experienced a departure from normal reimbursement from the payor community in 2013. We experienced an increase in denial of claims for certain services we provide and an increase in denial of our appeal for payment of these denied claims. As a result, the Company believed it needed to acquire new skills in collections. Consequently, we restructured and overhauled our billing department in late 2014/early 2015. We have already seen a significant increase in our collections related to our ResponseDX sales. We expect to continue to see improvements throughout 2015 and beyond from these efforts. We have engaged a seasoned billing/reimbursement expert on a consulting basis to assist with this overhaul and restructuring effort.

An allowance for doubtful accounts is recorded for estimated uncollectible amounts due from the Company’s various payor groups. The process for estimating the allowance for doubtful accounts involves significant assumptions and judgments. Specifically, the allowance for doubtful accounts is adjusted periodically, and is principally based upon an evaluation of historical collection experience of accounts receivable for the Company’s various payor classes. After appropriate collection efforts, accounts receivable are written off and deducted from the allowance for doubtful accounts. Additions to the allowance for doubtful accounts are charged to bad debt expense. The payment realization cycle for certain governmental and managed care payors can be lengthy, involving denial, appeal, and adjudication processes, and is subject to periodic adjustments that may be significant. The Company has a formal process to estimate and review the collectability of its receivables based on the period of time they have been outstanding. Bad debt expense is recorded within selling, general and administrative expenses at amounts necessary to maintain the allowance for doubtful accounts at an appropriate level. The Company’s process for determining the appropriate level of the allowance for doubtful accounts involves judgment, and considers such factors as the age of the underlying receivables, historical and projected collection experience, and other external factors that could affect the collectability of its receivables. Accounts are written off against the allowance for doubtful accounts based on the Company’s write-off policy ( e.g., when they are deemed to be uncollectible). In the determination of the appropriate level of the allowance, accounts are progressively reserved based on the historical timing of cash collections relative to their respective aging categories within the Company’s receivables. These collection and reserve processes, along with the close monitoring of the billing process, help reduce the risks of material revisions to reserve estimates resulting from adverse changes in collection or reimbursement experience.

We cannot guarantee that we will continue to experience the same credit loss rates that we have in the past. Measurement of such losses requires consideration of historical loss experience, including the need to adjust for current conditions, and judgments about the probable effects of relevant observable data, including present economic conditions such as delinquency rates and financial health of specific customers. We consider all available information in our assessments of the adequacy of the reserves for uncollectible accounts.

Income Taxes

We estimate our tax liability through calculations we perform for the determination of our current tax liability, together with assessing temporary differences resulting from the different treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are recorded in our balance sheets. Our management then assesses the likelihood that deferred tax assets will be recovered in future periods through future operating results. To the extent that we cannot conclude that it is more likely than not that the benefit of such assets will be realized, we establish a valuation allowance to adjust the net carrying value of such assets. The carrying value of our net deferred tax assets assumes that we will be able to generate sufficient future taxable income, based on management’s estimates and assumptions. These estimates and assumptions take into consideration future taxable income and ongoing feasible tax strategies in determining recoverability of such assets. Our valuation allowance is subject to significant change based on management’s estimates of future profitability and the ultimate realization of the deferred tax assets. The Company has established a full valuation allowance against its net deferred tax assets due to the uncertainty surrounding the realization of such assets.

Results of Operations

Quarters Ended March 31, 2015 and March 31, 2014

Revenue:   Revenue was $3,790,604 for the quarter ended March 31, 2015 as compared to $3,894,934 for the quarter ended March 31, 2014, a decrease of $104,330 or 2.7%. The decrease was due primarily to a decrease in pharmaceutical client revenue of $115,288 or 20.0%, offset by an increase in ResponseDX^® revenue of $10,958 or 0.3%. ResponseDX^® revenue accounted for 87.8% of total revenue for the quarter ended March 31, 2015 compared to 85.2% for the quarter ended March 31, 2014. The increase in ResponseDX^® revenue primarily relates to our continued focus on marketing and sales activities, the introduction of new programs (where the Company performs the technical component of testing and the client physician performs the related professional interpretation), and the introduction of the Response DX: Tissue of Origin^TM test. The decrease in pharmaceutical client revenue related to the completion of certain studies by pharmaceutical clients.

Cost of Revenue:   Cost of revenue for the quarter ended March 31, 2015 was $2,314,649 as compared to $2,438,376 for the quarter ended March 31, 2014, a decrease of $123,727 or 5.1%. The decrease in cost of revenue resulted primarily from decreases in the following costs: personnel costs of approximately $184,000, royalty expenses of approximately $37,000, equipment maintenance costs of approximately $25,000 and depreciation and amortization charges of approximately $18,000. These decreases were offset by higher laboratory supplies costs of approximately $148,000. The higher laboratory supplies costs resulted primarily from our expansion related to our new ResponseDX: Tissue of Origin^TM test, which launched during the quarter ended March 31, 2014 and is now fully integrated. Cost of revenue as a percentage of revenue was 61.1% for the quarter ended March 31, 2015, as compared to 62.6% for the quarter ended March 31, 2014.

Sales and Marketing Expenses:   Sales and marketing expenses were $949,726 for the quarter ended March 31, 2015 as compared to $1,452,905 for the quarter ended March 31, 2014, a decrease of $503,179 or 34.6%. The decrease was primarily to due lower costs, as follows: personnel costs of approximately $337,000, marketing and promotional expenses of approximately $92,000 and travel costs of approximately $74,000. The major expenditures for sales and marketing activities in both periods were compensation and travel expenses.

General and Administrative Expenses:   General and administrative expenses were $3,898,931 for the quarter ended March 31, 2015, as compared to $3,013,898 for the quarter ended March 31, 2014, an increase of $885,033 or 29.4%. This increase resulted primarily from increases in the following costs: bad debt expense of approximately $608,000, legal expenses of approximately $125,000, accounting and review fees of approximately $45,000, consulting fees of approximately $29,000, equipment maintenance costs of approximately $28,000, personnel costs of approximately $22,000 and other general operating expenses of approximately $28,000.

Research and Development Expenses:   Research and development expenses were $268,200 for the quarter ended March 31, 2015, as compared to $467,567 for the quarter ended March 31, 2014, a decrease of $199,367 or 42.6%. The decrease in expense was primarily the result of lower laboratory supplies costs of approximately $87,000, lower personnel costs of approximately $81,000 and lower legal fees of approximately $38,000. We intend to continue investing in research and development as we work to develop additional aspects of our technology, introduce new tests and to study diagnostic indicators for various forms of cancer.

Other Income and Expense:  Other income and expense primarily represents the interest expense we incur under the credit agreement with SWK Funding LLC as the agent and the lenders party thereto (the “SWK Credit Agreement”), amortization of deferred loan costs, our revolving credit facility with Silicon Valley Bank and equipment leases as well as realized and unrealized foreign currency exchange gains or losses on our Euro-denominated accounts receivable. Interest expense increased to $377,479 for the three months ended March 31, 2015 compared to $24,221 for the three months ended March 31, 2014. The increase was primarily due to the new SWK Credit Agreement and amortization of related debt issuance costs and debt discount. Other income (expense) increased to $1 for the three months ended March 31, 2015 compared to ($2,407) for the three months ended March 31, 2014. The change primarily relates to an increase in realized and unrealized foreign currency losses. 

Net Loss:   As a result of the foregoing, our net loss increased by $513,941 to $4,018,380 for the three months ended March 31, 2015 as compared to a net loss of $3,504,439 for the three months ended March 31, 2014.

Liquidity and Capital Resources

We incurred a net loss of $4,018,380 during the three months ended March 31, 2015. Since our inception in September 1999, we have incurred cumulative losses and as of March 31, 2015, we had an accumulated deficit of $83,014,921. We have not yet achieved profitability and anticipate that we will likely incur additional losses. We cannot provide assurance as to when we will achieve profitability. We expect that our cash and cash equivalents will be used to fund our selling and marketing activities primarily related to our ResponseDX^® tests, research and development, and general corporate purposes. As a result, we will need to generate significant revenues to achieve profitability.

The Company’s current operating plan includes various assumptions concerning the level and timing of cash receipts from sales and cash outlays for operating expenses and capital expenditures. The Company’s ability to successfully carry out its business plan is primarily dependent upon its ability to (1) obtain sufficient additional capital, (2) attract and retain knowledgeable workers, (3) increase its cash collections and (4) generate significant additional revenues. At this time, the Company expects to satisfy its future cash needs primarily through additional financing and/or strategic alternatives. The Company is currently seeking such additional financing and/or strategic alternatives; however, there can be no assurance that any additional financing or strategic alternatives will be available on acceptable terms, if at all. If the Company is unable to timely and successfully raise additional capital, implement strategic alternatives and/or achieve profitability, it will not have sufficient capital resources to implement its business plan or continue its operations, and the Company will most likely be required to reduce certain spending and/or curtail operations, which could have a material adverse effect on the Company’s ability to achieve its intended business objectives. These matters raise substantial doubt about the Company’s ability to continue as a going concern. No adjustments have been made to the accompanying unaudited condensed consolidated financial statements to reflect any of the matters discussed above.

Following is a summary of recent events and the expected impact these events have had or may have on our liquidity and future realization of revenues.

On July 30, 2014, (the “Closing Date”), we entered into a credit agreement (the “SWK Credit Agreement”) with SWK Funding LLC, as the administrative agent (the “Agent” or “SWK”), and the lenders (including SWK) party thereto from time to time (the “Lenders”). The SWK Credit Agreement provides for a multi-draw term loan to the Company (the “Loan”) up to a maximum principal amount of $12,000,000 (the “Loan Commitment Amount”). On the Closing Date, the Lenders advanced the Company an amount equal to $8,500,000 which is due and payable on July 30, 2020 (the “Term Loan Maturity Date”) or such earlier date on which the Loan Commitment Amount is terminated pursuant to the terms of the SWK Credit Agreement.

The Loan bears interest at a rate equal to the LIBOR Rate (as defined in the SWK Credit Agreement) plus an applicable margin of 12.5% per annum, subject to a one percent (1.0%) LIBOR floor. Interest on the Loan is due and payable in arrears (i) on the forty-fifth (45th) day following the last calendar day of each of the months of September, December, March, and June, commencing on November 15, 2014, (ii) upon a prepayment of the Loan and (iii) on the Term Loan Maturity Date. At December 31, 2014 and March 31, 2015, the interest rate charged to the Company was 13.5%. Upon the earlier of (a) the Term Loan Maturity Date or (b) full repayment of the Loan, the Company is also required to pay an exit fee. On February 3, 2015, the Company drew down an additional $1,500,000 under the SWK Credit Agreement, thereby increasing total borrowings under this facility to $10,000,000 as of March 31, 2015. On April 3, 2015, the Company drew down the remaining $2,000,000 under the SWK Credit Agreement, thereby increasing the total amount advanced to the Company under the SWK Credit Agreement to $12,000,000.

On July 14, 2011, the Company entered into a line of credit agreement with Silicon Valley Bank (the “Bank”), which agreement has been amended most recently on July 30, 2014. The line of credit is collateralized by all of the Company’s assets including its pharmaceutical, Private Payor and Medicare receivables. The maximum amount that can be borrowed from the line of credit is $2,000,000, subject to certain conditions. As of December 31, 2014 and March 31, 2015, the Company had drawn $1,500,000 and $1,465,662, respectively, against the line of credit. As of December 31, 2014 and March 31, 2015, the available amount the Company can draw from the line of credit was $500,000 and $463,677 respectively, calculated as the lesser of (i) the Company’s calculated borrowing base, which was 80% of certain of the Company’s accounts receivable, or (ii) the amount available under the line of credit. At December 31, 2014 and March 31, 2015, the interest rate charged to the Company was 5.5%, calculated by reference to the prime rate plus 2.25%. The line of credit’s maturity date is July 25, 2016.

The line of credit is subject to various covenants, including financial covenants that require the Company to maintain (i) an adjusted quick ratio of at least 1.25 to 1.00, (ii) quarterly rolling twelve-month net revenue balances beginning December 31, 2014 and (iii) quarterly minimum liquidity of $1,000,000. The Company’s revenue covenant and liquidity covenant under the line of credit agreement conform with, and are cross-defaulted with, equivalent covenants under the SWK Credit Agreement. At December 31, 2014 and March 31, 2015, the Company was in compliance with its covenants under the line of credit agreement. Historically, however, the Company has been out of compliance with certain covenants from time to time, and the Company has received waivers and forbearance agreements from the Bank.

From time to time, the Company’s calculated borrowing base under its Bank line of credit may decrease to a level where the Company is in an over-advance position in which case the Company will be required to repay any outstanding amounts greater than the calculated borrowing base for such covered period back to the Bank immediately. The Company will be able to draw down on the credit line again with respect to such paid-back amount once the Company is in compliance with the borrowing base requirement.

As of December 31, 2014 and March 31, 2015, the line of credit under the credit agreement was classified as a non-current liability of the Company on the accompanying condensed consolidated balance sheet, as the line of credit had a maturity date of greater than one year from the date of the balance sheet.

Comparison of Cash Flows for the Three Months Ended March 31, 2015 and 2014

As of March 31, 2015, we had $1,734,661 in cash and cash equivalents, working capital of $3,878,728 and an accumulated deficit of $83,014,921. As of March 31, 2014, we had $4,956,503 in cash and cash equivalents, working capital of $5,511,476 and an accumulated deficit of $68,801,618.

Cash flows used in operating activities

During the three months ended March 31, 2015, the Company used cash flows in operating activities of $1,880,332 compared to $3,095,012 used in the three months ended March 31, 2014. The decrease in cash used in operating activities of $1,214,680 was due mainly to an increase in non-cash items offset by the increase in net loss from $3,504,439 for the three months ended March 31, 2014 to $4,018,380 for the three months ended March 31, 2015. Other items that impacted cash flows from operating activities include improved cash collections related to our ResponseDX receivables, decreased accrued expenses and payroll related liabilities, offset by increases in prepaid expenses and accounts payable.

Cash flows used in investing activities

Net cash used in investing activities was $2,411 for the three months ended March 31, 2015 and $44,559 for the three months ended March 31, 2014. The reduction in cash used in investing activities was attributable to lower purchases of equipment and software.

Cash flows provided by financing activities

Cash flows provided by financing activities for the three months ended March 31, 2015 increased $1,422,821 primarily from issuance of new debt, offset by paydowns on capital leases and the line of credit. Cash flows from financing activities for the three months ended March 31, 2014 used net cash of $30,296 for repayment of capital lease obligations net of proceeds received from the exercise of stock options.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

Recent Accounting Pronouncements

In April 2015, the Financial Accounting Standards Board issued ASU 2015-03 “Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” ASU 2015-03 requires an entity to present debt issuance costs related to a recognized debt liability in the balance sheet as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this update. The amendment will be effective for the Company’s annual and interim reporting periods beginning January 1, 2016 and should be applied on a retrospective basis. The adoption of ASU 2015-03 will not have any impact on the Company’s results of operations, but will result in debt issuance costs being presented as a direct reduction from the carrying amount of debt liabilities.  This standard will not have a material impact on the Company’s consolidated financial statements.

In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which modifies how all entities recognize revenue, and consolidates into one Accounting Standards Codification ("ASC") Topic (ASC Topic 606, Revenue from Contracts with Customers) the current guidance found in ASC Topic 605, Revenue Recognition, and various other revenue accounting standards for specialized transactions and industries. The core principle of the guidance is that “an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” In achieving this objective, an entity must perform five steps: (1) identify the contract(s) with a customer, (2) identify the performance obligations of the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 also clarifies how an entity should account for costs of obtaining or fulfilling a contract in a new ASC Subtopic 340-40, Other Assets and Deferred Costs – Contracts with Customers.

ASU 2014-09 is effective for public companies for annual periods beginning after December 15, 2016 and interim periods within those annual periods, and early adoption is not permitted. ASU 2014-09 may be applied using either a full retrospective approach, in which all years included in the financial statements are presented under the revised guidance, or a modified retrospective approach. Under the modified retrospective cumulative catch-up approach, financial statements will be prepared using the new standard for the year of adoption, but not for prior years. Under this method, entities will recognize a cumulative catch-up adjustment to the opening balance of retained earnings at the effective date for contracts that still require performance by the Company and disclose all line items in the year of adoption as if they were prepared under the old revenue guidance. The Company is currently evaluating the impact of ASC 606, but at the current time does not know what impact the new standard will have on revenue recognized and other accounting decisions in future periods, if any, nor what method of adoption will be selected if the impact is material.

In August 2014, the Financial Accounting Standards Board issued ASU No. 2014-15, Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU 2014-09”). ASU 2014-15 provides guidance on management's responsibility in evaluating whether there is substantial doubt about a company's ability to continue as a going concern and about related footnote disclosures. For each reporting period, management will be required to evaluate whether there are conditions or events that raise substantial doubt about a company's ability to continue as a going concern within one year from the date the financial statements are issued. ASU 2014-15 is effective for annual periods ending after December 15, 2016, and interim periods thereafter; earlier adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial condition, results of operations or cash flows.

ITEM 3. Quantitative and Qualitative Disclosures about Market Risk.

Not applicable.

ITEM 4. Controls and Procedures.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. Under the supervision, and with the participation of our management, including the Principal Executive Officer and Principal Financial Officer, we have evaluated the effectiveness of our disclosure controls and procedures pursuant to Exchange Act Rules 13a-15 and 15d-15 as of the end of the period covered by this report. Based on that evaluation, our Principal Executive Officer and Principal Financial Officer have concluded that these disclosure controls and procedures were effective as of the end of the period covered by this report.

It should be noted that any system of controls and procedures, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. As a result, there can be no assurance that a control system will succeed in preventing all possible instances of error and fraud. Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives, and the conclusions of our Principal Executive Officer and the Principal Financial Officer are made at the “reasonable assurance” level.

There were no changes in our internal control over financial reporting during the quarter ended March 31, 2015 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

PART II. OTHER INFORMATION

Earnings Per Share [Abstract]

Loss Per Share

4. Loss Per Share

The Company calculates net loss per share in accordance with ASC 260, Earnings Per Share. Under the provisions of ASC 260, basic net loss per share is computed by dividing the net loss for the period by the weighted average number of shares of common stock outstanding for the period. Diluted net loss per share is computed by dividing the net loss by the weighted average number of shares of common stock and dilutive common stock equivalents then outstanding. Common stock equivalents consist of shares of common stock issuable upon the exercise of stock options and warrants.

The following table sets forth the computation for basic and diluted loss per share:

	Three Months Ended March 31,
	2014		2015
Numerator:
Net loss	$	(3,504,439)	$	(4,018,380)
Numerator for basic and diluted earnings per share	$	(3,504,439)	$	(4,018,380)
Denominator:
Denominator for basic and diluted earnings per share — weighted-average shares		38,718,336		38,795,396
Basic and diluted loss per share	$	(0.09)	$	(0.10)

Outstanding stock options to purchase 2,217,134 and 2,461,078 shares of common stock of the Company for the periods ended March 31, 2014 and 2015, respectively, were excluded from the calculation of diluted loss per share as their effect would have been antidilutive. Also excluded from the calculation were 270,000 unvested shares of restricted common stock for both of the periods ended March 31, 2014 and 2015. Outstanding warrants to purchase 1,258,013 shares of common stock of the Company for the period ended March 31, 2015 were also excluded in the calculation of diluted loss per share.

Organization, Operations and Basis of Accounting

1. Organization, Operations and Basis of Accounting

Response Genetics, Inc. (the “Company”) was incorporated in the State of Delaware on September 23, 1999 as Bio Type, Inc. for the purpose of providing molecular profiling services of tumor tissue that has been formalin-fixed and embedded in paraffin. In August 2000, the Company changed its name to Response Genetics, Inc.

The Company is a life science company engaged in the research, development, marketing and sale of pharmacogenomics-clinical diagnostic tests for cancer. Pharmacogenomics is the science of how an individual’s genetic makeup relates to drug response. Diagnostic tests based on pharmacogenomics facilitate the prediction of a response to drug therapy or survival following surgery based on an individual’s genetic makeup. In order to generate pharmacogenomic information from patient specimens for these tests, the Company uses its proprietary technologies that enable the Company to reliably and consistently extract ribonucleic acid (“RNA”) and deoxyribonucleic acid (“DNA”) from tumor specimens that are stored as formalin-fixed and paraffin-embedded (“FFPE”) specimens and, thereby to analyze genetic information contained in these tissues for each patient. The Company’s platforms include analysis of single biomarkers using the polymerase chain reaction method as well as global gene interrogation using microarray methods and fluorescence in situ hybridization (“FISH”) from paraffin or frozen tissue specimens. The Company primarily derives its revenue from the sale of its ResponseDX^® diagnostic testing products and by providing pharmacogenomic clinical trial testing services to pharmaceutical companies in the United States, Asia and Europe.

The Company’s goal is to provide cancer patients and their physicians with a means to make informed, individualized treatment decisions based on genetic analysis of tumor tissues. The Company’s pharmacogenomic analysis of clinical trial specimens for the pharmaceutical industry may provide data that will lead to a better understanding of the molecular basis for response to specific drugs and, therefore lead to individualized treatment.

Liquidity and Management’s Plans

Since its inception, the Company has devoted substantial effort in developing its products and has incurred losses and negative cash flows from operations. At March 31, 2015, the Company had an accumulated deficit of $83,014,921. The Company anticipates continued losses and negative cash flows as it funds its selling and marketing activities and research and development programs.

The Company’s current operating plan includes various assumptions concerning the level and timing of cash receipts from sales and cash outlays for operating expenses and capital expenditures. The Company’s ability to successfully carry out its business plan is primarily dependent upon its ability to (1) obtain sufficient additional capital at acceptable costs, (2) attract and retain knowledgeable employees and (3) generate significant additional revenues. At this time, the Company expects to satisfy its future cash needs primarily through additional financing and/or strategic alternatives. The Company is currently seeking such additional financing and/or strategic alternatives; however, there can be no assurance that any additional financing or strategic alternatives will be available on acceptable terms, if at all. If the Company is unable to timely and successfully raise additional capital, implement strategic alternatives and/or achieve profitability, it will not have sufficient capital resources to implement its business plan or continue its operations, and the Company will most likely be required to reduce certain spending and/or curtail operations, which could have a material adverse effect on the Company’s ability to achieve its intended business objectives. These matters raise substantial doubt about the Company’s ability to continue as a going concern. No adjustments have been made to the accompanying unaudited condensed consolidated financial statements to reflect any of the matters discussed above.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with the instructions for Form 10-Q promulgated by the Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the fiscal year. The balances as of December 31, 2014 were derived from our audited financial statements as of December 31, 2014. The financial statements should be read in conjunction with the Company’s audited December 31, 2014 and 2013 consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K previously filed with the SEC on March 31, 2015.

Schedule of Assumptions Used to Estimate Share-Based Compensation Expense Using Black-Scholes Model

Except for certain grants of restricted common stock and common stock options containing market conditions as described below, the Company estimated share-based compensation expense for the three months ended March 31, 2015* using the Black-Scholes model with the following weighted average assumptions:

	Three Months Ended March 31, 2015
Risk free interest rate		1.68	%
Expected dividend yield		—	%
Expected volatility		99.2	%
Expected term **(in years)		6.25
Forfeiture rate ***		7.0	%

*     There were no stock options issued for the three months ended March 31, 2014.

** Expected term is calculated using SAB 107, Simplified Formula. Management has concluded that the use of the simplified method for calculating the expected term of its common stock option grants is appropriate given the lack of historical exercises and the standard terms of the employee option grants, including, options are granted at-the-money, exercise is conditional only on performing service through the vesting dates, termination of service causes forfeiture of options, employees have a limited number of days to exercise options after termination of service, and options are non-transferable.

*** Forfeiture range represents 0% for directors and 21% for employees

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Basis of Consolidation

The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Response Genetics, Ltd., a Scottish corporation (the “Subsidiary”), which was incorporated in November 2006. The Subsidiary had no employees or active operations in 2014 or to date in 2015. All significant intercompany transactions and balances have been eliminated in consolidation.

Cash and Cash Equivalents

The Company considers all highly liquid investments with a maturity date of three months or less from the date of purchase to be cash equivalents. The carrying value of cash equivalents approximates fair value due to the short-term nature and liquidity of these instruments. The Company’s cash equivalents are comprised of cash on hand, deposits in banks and money market investments.

Accounts Receivable

Pharmaceutical Accounts Receivable

The Company invoices its clients as specimens are processed and any other contractual obligations are met. The Company’s contracts with clients typically require payment within 45 days of the date of invoice. The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of its clients to make required payments. The Company specifically analyzes accounts receivable and historical bad debts, client credit, current economic trends and changes in client payment trends when evaluating the adequacy of the allowance for doubtful accounts. Account balances are charged-off against the allowance when it is probable the receivable will not be recovered. To date, the Company’s pharmaceutical customers have primarily been large pharmaceutical companies. As a result, bad debts from pharmaceutical accounts receivable to date have been minimal. Pharmaceutical company accounts receivable as of December 31, 2014 and March 31, 2015 were $1,037,834 and $454,773, respectively. There were no allowances for doubtful accounts recorded against these pharmaceutical accounts receivable at December 31, 2014 and March 31, 2015.

ResponseDX^® Accounts Receivable

ResponseDX^® accounts receivable are recorded from two primary payors: (1) Medicare and (2) third party payors such as commercial insurance and private payors or self-paying payors (“Private Payors”). ResponseDX^® accounts receivable are recorded at established billing rates less an estimated billing adjustment, based on reporting models utilizing historical cash collection percentages and updated for current effective reimbursement factors.  Management performs ongoing valuations of accounts receivable balances based on management’s evaluation of historical collection experience and industry trends.  Based on the historical experience for our accounts, management has determined, based on a detailed analysis, that accounts receivable associated with certain billings are unlikely to be collected. Therefore, the Company has recorded an allowance for doubtful accounts of $2,071,706 and $2,226,890 as of December 31, 2014 and March 31, 2015, respectively. The Company’s bad debt expense for the three months ended March 31, 2014 and 2015 was $1,293,850 and $1,902,144, respectively.

ResponseDX^® accounts receivable as of December 31, 2014 and March 31, 2015, consisted of the following:

 

	December 31, 2014			March 31, 2015
Net Medicare receivable	$	2,814,989		$	2,191,781
Net Private Payor receivable		6,029,300			5,639,447
		8,844,289			7,831,228
Allowance for doubtful accounts		(2,071,706	)		(2,226,890	)
Total	$	6,772,583		$	5,604,338

At December 31, 2014 and March 31, 2015, all Medicare accounts receivable outstanding for a period of greater than one year have been reserved 100%.

Property and Equipment

Property and equipment are carried at cost less accumulated depreciation and amortization. Depreciation and amortization are calculated using the straight-line methods over the estimated useful lives of the assets. The Company has determined the estimated useful lives of its property and equipment, as follows:

Laboratory equipment	5 to 7 years
Furniture and equipment	3 to 7 years
Purchased and internally-developed software	3 to 5 years
Leasehold improvements	Shorter of the useful life (5 to 7 years) or the lease term

 

Maintenance and repairs are charged to expense as incurred. The cost and accumulated depreciation of assets sold or otherwise disposed of are removed from the related accounts and the resulting gain or loss is reflected in the statements of operations. The Company has capitalized costs related to the development of database software (see Note 3). The portion of this database placed into service is amortized in accordance with ASC 350-40, Internal-Use Software. The amortization period is five years using the straight-line method.

Revenue Recognition

Pharmaceutical Revenue

Revenues that are derived from testing services provided to pharmaceutical companies are recognized on a contract specific basis pursuant to the terms of the related agreements. Revenue is recognized in accordance with ASC 605, Revenue Recognition, which requires that four basic criteria must be met before revenue can be recognized: (1) persuasive evidence that an arrangement exists; (2) delivery has occurred and title and the risks and rewards of ownership have been transferred to the client or services have been rendered; (3) the price is fixed or determinable; and (4) collectability is reasonably assured.

Revenues are recorded on an accrual basis as the contractual obligations are completed and as a set of assays is processed through the Company’s laboratory under a specified contractual protocol and are recorded on the date the tests are completed. Certain contracts have minimum assay requirements that, if not met, result in payments that are due upon the completion of the designated period. In these cases, revenues are recognized when the end of the specified contract period is reached.

On occasion, the Company may enter into a contract that requires the client to provide an advance payment for specimens that will be processed at a later date. In these cases, the Company records this advance as deferred revenue and recognizes the revenue as the specimens are processed or at the end of the contract period, as appropriate. There was no deferred revenue at December 31, 2014 or March 31, 2015.

The Company recorded revenue from pharmaceutical clients for the three months ended March 31, 2014 and 2015 of $577,381 and $462,093, respectively.

ResponseDX^® Revenue

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.

Services are provided to certain patients covered by various third-party payer programs including various managed care organizations, commercial insurance plans and Medicare programs. Billings for services under third-party payer programs are included in revenue net of allowances for contractual discounts and allowances for differences between the amounts billed and estimated payment amounts. Significant judgment is inherent in the selection of assumptions and the interpretation of historical experience as well as the identification of external and internal factors affecting the determination of these reserves for Medicare, private health insurance companies, healthcare institutions, and patients.

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 assumptions used to determine these contractual allowances are reasonable considering known facts and circumstances. If actual future payments are less than the estimates the Company made at the time of recognizing revenue, the consolidated financial position, results of operations and cash flows may be negatively impacted. If actual future payments are materially different from the contracted amounts or estimates, the difference is accounted for as a change in estimate in the period in which they become known. Adjustments to the estimated payment amounts based on final settlement are recorded upon settlement as an adjustment to revenue.

For the three months ended March 31, 2014 and 2015, approximately 39% and 42%, respectively, of the Company's ResponseDX^® revenues were derived directly from the Medicare program. The Company’s Medicare provider number allows it to invoice and collect from Medicare. The Company’s invoicing to Medicare is primarily based on amounts allowed by Medicare for the service provided as defined by Common Procedural Terminology (“CPT”). Laws and regulations governing the Medicare program and healthcare generally are complex and subject to interpretation.

The following details ResponseDX^® revenue for the periods indicated:

	Three Months
	Ended March 31,
	2014		2015
Net Medicare revenue	$	1,308,422	$	1,408,241
Net Private Payor revenue		2,009,131		1,920,270
Net ResponseDX® revenue	$	3,317,553	$	3,328,511

The Company recognizes revenue for services covered by Medicare based on the Medicare fee schedule. For 2014, the Company’s Medicare fees were based on the Centers for Medicare and Medicaid Services (“CMS”) proposed “Medicare Program; Revisions to Payment Policies under the Physician Fee Schedule, Clinical Laboratory Fee Schedule & Other Revisions to Part B for CY 2014” released in July 2013. For the three months ended March 31, 2015, the Company’s fees were based on the Centers for Medicare and Medicaid Services (“CMS”) fee schedules released in December 2014.

The Company updates its estimates of Medicare fees based on current information from CMS. The nature of the testing services the Company provides, the evidence the Company gathers to establish the creditworthiness of its payors and the delivery method of its services have not changed from prior periods, and therefore these assumption remain appropriate.

Cost of Revenue

Cost of revenue represents the cost of materials, direct labor, royalties, costs associated with processing tissue specimens including pathological review, staining, microdissection, paraffin extraction, reverse transcription polymerase chain reaction (“PCR”), fluorescence in situ hybridization (“FISH”), quality control analyses, license fees and delivery charges necessary to render an individualized test result. Costs associated with performing tests are recorded as the tests are processed.

License Fees

The Company has licensed technology for the extraction of ribonucleic acid (“RNA”) from formalin-fixed, paraffin-embedded tumor specimens from the University of Southern California (“USC”). Under the terms of the license agreement, the Company is required to pay royalties to USC calculated as a fixed percentage of the net sales price as defined in the agreement that the Company generates by using this technology. Total license fees expensed in cost of revenue under the license agreement with USC were $10,961 and $5,508 for the three months ended March 31, 2014 and 2015, respectively. The Company also maintains a non-exclusive license to use certain patents related to the PCR of Roche Molecular Systems, Inc. (“Roche”). The Company pays Roche a royalty fee based on revenue that the Company generates through use of this technology. The Company accrues for such royalties at the time revenue is recognized. Royalties expensed in cost of revenue under the Roche agreement totaled $44,373 and $16,265 for the three months ended March 31, 2014 and 2015, respectively. Such royalties are included in cost of revenues in the accompanying statements of operations.

The Company is subject to potentially significant variations in royalties recorded in any period. While the amount paid is based on a fixed percentage of net sales price as defined in the agreement of specific tests pursuant to terms set forth in the agreements with USC and Roche, the amount due is calculated based on the revenue we recognize using the respective licensed technology. As discussed above, this revenue can vary from period to period as it is dependent on the timing of the specimens submitted by our clients for testing.

Additionally, the Company periodically analyzes the technical procedures performed in its test offerings to assess which activities utilize licensed technologies and to calculate royalties for use of the licensed technology. The most recent analyses indicate that the Company could owe less than the amounts that have been accrued for royalties payable. Roche is still reviewing the Company’s updated royalty calculations. It is possible that based on Roche’s review and the Company’s discussions with Roche, the Company may further adjust its Roche royalty accrual.

Research and Development

The Company expenses costs associated with research and development activities as incurred. Research and development costs are expensed as incurred and classified as research and development costs. Research and development costs include employee costs (salaries, payroll taxes, benefits, and travel), equipment depreciation and maintenance, laboratory supplies, primers and probes, reagents, patent costs and occupancy costs.

Line of Credit

On July 14, 2011, the Company entered into a line of credit agreement with Silicon Valley Bank (the “Bank”), which agreement has been amended most recently on July 30, 2014. The line of credit is collateralized by all of the Company’s assets including its pharmaceutical, Private Payor and Medicare receivables. The maximum amount that can be borrowed from the line of credit is $2,000,000, subject to certain conditions. As of December 31, 2014 and March 31, 2015, the Company had drawn $1,500,000 and $1,465,662, respectively, against the line of credit. As of December 31, 2014 and March 31, 2015, the available amount the Company can draw from the line of credit was $500,000 and $463,677, respectively, calculated as the lesser of (i) the Company’s calculated borrowing base, which was 80% of certain of the Company’s accounts receivable, or (ii) the amount available under the line of credit. During the first half of 2014, the interest rate charged to the Company on the line of credit was 5%, calculated by reference to the prime rate plus 1.75%. For the latter half of 2014 and the three months ended March 31, 2015, the rate charged to the Company was 5.5%, calculated by reference to the prime rate plus 2.25%. The line of credit’s maturity date is July 25, 2016.

The line of credit is subject to various covenants, including financial covenants that require the Company to maintain (i) an adjusted quick ratio of at least 1.25 to 1.00; (ii) quarterly rolling twelve-month net revenue balances beginning December 31, 2014; and (iii) quarterly minimum liquidity of $1,000,000. The Company’s revenue covenant and liquidity covenant under the line of credit agreement conform with, and are cross-defaulted with equivalent covenants under the SWK Credit Agreement (as described below.) At December 31, 2014 and March 31, 2015, the Company was in compliance with its covenants under the line of credit agreement. Historically, however, the Company has been out of compliance with certain covenants from time to time, and the Company has received waivers and forbearance agreements from the Bank.

From time to time, the Company’s calculated borrowing base under its Bank line of credit may decrease to a level where the Company is in an over-advance position in which case the Company will be required to repay any outstanding amounts greater than the calculated borrowing base for such covered period back to the Bank immediately. The Company will be able to draw down on the credit line again with respect to such paid-back amount once the Company is in compliance with the borrowing base requirement.

As of December 31, 2014 and March 31, 2015, the line of credit under the credit agreement was classified as a non-current liability of the Company on the accompanying condensed consolidated balance sheet as the line of credit had a maturity date of greater than one year from the date of the balance sheet.

SWK Term Loan

On July 30, 2014 (the “Closing Date”), the Company entered into a credit agreement (the “SWK Credit Agreement”) with SWK Funding LLC, as the administrative agent (the “Agent” or “SWK”), and the lenders (including SWK) party thereto from time to time (the “Lenders”). The SWK Credit Agreement provides for a multi-draw term loan to the Company (the “Loan”) up to a maximum principal amount of $12,000,000 (the “Loan Commitment Amount”). On the Closing Date, the Lenders advanced the Company an amount equal to $8,500,000 which is due and payable on July 30, 2020 (the “Term Loan Maturity Date”) or such earlier date on which the Loan Commitment Amount is terminated pursuant to the terms of the SWK Credit Agreement. On February 3, 2015 (the “Amendment Closing Date”), the Company and SWK entered into a first amendment (the “Amendment”) to the SWK Credit Agreement.  Pursuant to the Amendment, the Company drew an additional $1,500,000 of the Loan Commitment Amount thereby increasing the total amount advanced to the Company under the SWK Credit Agreement to $10,000,000.

The Loan bears interest at a rate equal to the LIBOR Rate (as defined in the SWK Credit Agreement) plus an applicable margin of 12.5% per annum, subject to a one percent (1.0%) LIBOR floor. Interest on the Loan is due and payable in arrears (i) on the forty-fifth (45th) day following the last calendar day of each of the months of September, December, March, and June, commencing on November 15, 2014, (ii) upon a prepayment of the Loan and (iii) on the Term Loan Maturity Date. At December 31, 2014 and March 31, 2015, the interest rate charged to the Company was 13.5%. Upon the earlier of (a) the Term Loan Maturity Date or (b) full repayment of the Loan, the Company is also required to pay an exit fee. On September 9, 2014, SWK, in its capacity as the initial Lender, assigned part of its interests under the SWK Credit Agreement to SG-Financial, LLC (“SG”). Pursuant to the assignment, SG was assigned $2,500,000 of the $8,500,000 Closing Date initial advance to the Company and $1,029,412 of the subsequent term loan commitment. On January 30, 2015, SG assigned all of its interests under the SWK Credit Agreement back to SWK.

On the Closing Date, the Company issued to the Agent a warrant (the “Initial Warrant”) to purchase up to 681,090 shares of the Company's common stock. The Initial Warrant was exercisable, in whole or in part, from the date of issuance until and including July 30, 2020 at an exercise price of $0.936 per share, subject to adjustment. The Initial Warrant was valued at $414,239, or approximately $0.61 per covered share, using a Black-Scholes pricing model with the following assumptions: 2.01% risk free rate, 0% dividend, 101.5% volatility, and six-year expected life. The value of the warrant was recorded on the balance sheet included in additional paid-in capital. On September 9, 2014, the Agent assigned a portion of the Initial Warrant consisting of the right to purchase 200,321 shares of common stock to SG (the “SG Initial Warrant”). On January 30, 2015, SG assigned the SG Initial Warrant back to the Agent and on the Amendment Closing Date, the Company replaced the Initial Warrant to purchase the total 681,090 shares of the Company’s common stock with a new warrant with an adjusted exercise price (the “Replacement Warrant”).   The Replacement Warrant is exercisable up to and including July 30, 2020 at an exercise price of $0.39 per share.  The Agent may exercise the Replacement Warrant on a cashless basis at any time.  In the event the Agent exercises the Replacement Warrant on a cashless basis, the Company will not receive any proceeds.  The exercise price of the Replacement Warrant is subject to customary adjustments for stock splits, stock dividends, recapitalizations and the like.

For accounting purposes, the proceeds received in the July 2014 transaction were allocated to the liability for debt, a debt issuance discount and additional paid-in capital for the warrant based upon the relative fair value of the loan and the warrant. The amounts recorded in the financial statements were $8,500,000 for loan liability, $576,161 for debt issuance discount and $377,140 to additional paid-in capital for the warrant. Additionally, the Company recorded deferred loan issuance costs of $187,092 for investment banker fees and legal fees incurred to enter into the SWK Credit Agreement. The debt issuance discount and the deferred issuance costs are being amortized to interest expense over the six-year term of the loan. Upon the re-issuance of the Replacement Warrant on February 3, 2015 at a reduced exercise price of $0.39, the debt issuance discount was re-valued at $599,305 and a $23,144 increase in the warrant value was recorded as an increase to debt discount and additional paid-in capital. The Replacement Warrant transaction was determined to be a debt modification.

In addition, on the Amendment Closing Date, the Company issued the Agent a new warrant (the “First Amendment Warrant”) to purchase 576,923 shares of Common Stock.  The First Amendment Warrant is exercisable up to and including February 3, 2021 at an exercise price of $0.39 per share, subject to adjustment.  The First Amendment Warrant was valued at $167,712, or approximately $0.29 per covered share, using a Black-Scholes pricing model with the following assumptions: 1.39% risk free rate, 0% dividend, 90.9% volatility and six-year expected life. The value of the warrant was recorded on the balance sheet included in additional paid-in capital. The Agent may exercise the First Amendment Warrant on a cashless basis at any time.  In the event the Agent exercises the First Amendment Warrant on a cashless basis, the Company will not receive any proceeds.  The exercise price of the First Amendment Warrant is subject to customary adjustments for stock splits, stock dividends, recapitalizations and the like.

Additionally, for accounting purposes, the proceeds received in the February 2015 transaction were allocated to the liability for debt, a debt issuance discount and additional paid-in capital for the warrant based upon the relative fair value of the loan and the warrant. The amounts recorded in the financial statements were $1,500,000 for loan liability, $168,372 for debt issuance discount and $148,887 to additional paid-in capital for the warrant. Additionally, the Company recorded deferred loan issuance costs of $19,485 for investment banker fees and legal fees incurred to enter into the Amendment. The debt issuance discount and the deferred issuance costs are being amortized to interest expense over the six-year term of the loan.

The Company may prepay the Loan, in whole or in part, upon five business days’ written notice provided that a prepayment premium is paid to the Lenders as set forth in the SWK Credit Agreement. The Company is required to prepay the Loan with any net cash proceeds received from certain types of dispositions of assets described in the SWK Credit Agreement. The Company is also required to make certain revenue-based payments on the Company’s quarterly revenues, applied in the following priority: (i) first, to the payment of all fees, costs, expenses and indemnities due and owing to the Agent under the SWK Credit Agreement, (ii) second, to the payment of all fees, costs, expenses and indemnities due and owing to the Lenders under the SWK Credit Agreement, (iii) third, to the payment of all accrued but unpaid interest until paid in full, (iv) fourth, for each revenue-based payment date after August 2016, to the payment of all principal of the Loan up to an aggregate amount of $750,000 on any such payment date and (v) fifth, all remaining amounts to the Company.

As of December 31, 2014 and March 31, 2015, the term debt under SWK Credit Agreement was classified as a non-current liability of the Company on the accompanying balance sheet as the repayment terms are based on future revenues that cannot be reasonably estimated and therefore all outstanding amounts are classified as non-current.

The SWK Credit Agreement contains customary affirmative and negative covenants for credit facilities of its type, including covenants that limit the Company’s ability to pay dividends or redeem outstanding equity interests, incur additional indebtedness, grant additional liens, engage in any other type of business, make investments, merge, consolidate or sell all or substantially all of its assets and enter into transactions with related parties. The SWK Credit Agreement also contains certain financial covenants, including certain minimum aggregate revenue requirements. The Company was in compliance with these covenants at December 31, 2014 and March 31, 2015.

The SWK Credit Agreement includes customary events of default, including failure to pay principal, interest or fees when due, failure to comply with covenants, default under certain other indebtedness, certain insolvency or bankruptcy events, the occurrence of certain material judgments, the institution of any proceeding by a government agency or a change of control of the Company that is not otherwise permitted under the SWK Credit Agreement.

Refer to Note 11 to these unaudited condensed consolidated financial statements for a description of the second amendment to the SWK Credit Agreement, dated April 3, 2015, pursuant to which the Company drew the remaining $2,000,000 of the Loan Commitment Amount and issued certain of the Lenders warrants to purchase an aggregate 2,702,702 shares of Common Stock.

Income Taxes

Deferred tax assets and liabilities are determined based on differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.

ASC 740, Income Taxes, clarifies the accounting for uncertainty in income taxes recognized in financial statements and requires the impact of a tax position to be recognized in the financial statements if that position is more likely than not of being sustained by the taxing authority. As of December 31, 2014 and March 31, 2015, the Company does not have a liability for unrecognized tax benefits. The Company recognizes interest and penalties associated with tax matters as part of the income tax provision, and includes accrued interest and penalties with the related tax liability in the balance sheet. For the periods ended March 31, 2014 and 2015, there were no interest and penalties recorded in the Condensed Consolidated Statement of Operations.

Stock-Based Compensation

The Company accounts for stock-based compensation in accordance with ASC 718, Stock Compensation, Share-Based Payment. Stock-based compensation expense for all stock-based compensation awards granted is based on the grant-date fair value estimated in accordance with the provisions of ASC 718. The Company recognizes these compensation costs on a straight-line basis over the requisite service period of the award, which is generally the option vesting period. As further described in Note 7, certain awards granted to Thomas A. Bologna, the Company’s Chairman and Chief Executive Officer, were recognized based on an accelerated vesting basis triggered by market conditions rather than a straight-line basis.

The Company accounts for equity instruments issued to non-employees in accordance with ASC 505, Equity. Under ASC 505, stock option awards issued to non-employees are measured at fair value using the Black-Scholes option-pricing model and recognized pursuant to a performance model.

Management Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates in these condensed consolidated financial statements have been made for revenue, allowances for doubtful accounts, impairment of long-lived assets, depreciation of property and equipment and stock-based compensation. Actual results could differ materially from those estimates.

Long-lived Assets

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company evaluates potential impairment by comparing the carrying amount of the asset with the estimated undiscounted future cash flows associated with the use of the asset and its eventual disposition. Should the review indicate that the assets cost is not recoverable, the carrying value of the asset would be reduced to its fair value, which is measured by future discounted cash flows.

Foreign Currency Translation

The financial position and results of operations of the Company’s foreign subsidiary are determined using local currency as the functional currency. Assets and liabilities of these operations are translated at the exchange rate in effect at each period-end. Statement of Operations amounts are translated at the average rate of exchange prevailing during the period. Translation adjustments arising from the use of differing exchange rates from period to period are included in accumulated other comprehensive loss in stockholders’ deficit.

Comprehensive Loss

The components of comprehensive loss are accumulated net loss and foreign currency translation adjustments for the three months ended March 31, 2014 and 2015.

Fair Value of Financial Instruments

Cash and cash equivalents are stated at cost, which approximates fair market value.  Cash equivalents consist of money market accounts, with fair values estimated based on quoted market prices. Debt balances are stated at historical amounts less principal payments, which approximate fair market value. The Company believes interest rates in its debt agreements are commensurate with lender risk profiles for similar companies.

Advertising Costs

The Company markets its services through its advertising activities in trade publications and on the internet. Advertising costs are included in selling and marketing expenses on the statements of operations and are expensed as incurred. Advertising costs for the three months ended March 31, 2014 and 2015 were $6,422 and $17,124, respectively. 

Concentration of Credit Risk and Clients and Limited Suppliers

Cash and cash equivalents are maintained at financial institutions and, at times, balances may exceed federally insured limits. The Company has never experienced any losses related to these balances. At March 31, 2015, the Company had $1,476,222 in cash and cash equivalents that exceeded federally insured limits. At March 31, 2015, $7,803 of cash was held outside of the United States.

Many of the supplies and reagents used in the Company’s testing process are procured from a limited number of suppliers. Any supply interruption or an increase in demand beyond the suppliers’ capabilities could have an adverse impact on the Company’s business. Management believes it can identify alternative sources, if necessary, but it is possible such sources may not be identified in sufficient time to avoid an adverse impact on its business. The Company purchases certain laboratory supplies and reagents primarily from a limited number of suppliers. The Company made approximately 73% of its reagent purchases from four suppliers during the year ended December 31, 2014 and made approximately 70% of its reagent purchases from three suppliers during the three months ended March 31, 2015.

Recent Accounting Pronouncements

In April 2015, the FASB issued ASU 2015-03 “Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” ASU 2015-03 requires an entity to present debt issuance costs related to a recognized debt liability in the balance sheet as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this update. The amendment will be effective for the Company’s annual and interim reporting periods beginning January 1, 2016 and should applied on a retrospective basis. The adoption of ASU 2015-03 will not have any impact on the Company’s results of operations, but will result in debt issuance costs being presented as a direct reduction from the carrying amount of debt liabilities.  This standard will not have a material impact on the Company’s consolidated financial statements.

In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which modifies how all entities recognize revenue, and consolidates into one Accounting Standards Codification ("ASC") Topic (ASC Topic 606, Revenue from Contracts with Customers) the current guidance found in ASC Topic 605, Revenue Recognition, and various other revenue accounting standards for specialized transactions and industries. The core principle of the guidance is that “an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” In achieving this objective, an entity must perform five steps: (1) identify the contract(s) with a customer, (2) identify the performance obligations of the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 also clarifies how an entity should account for costs of obtaining or fulfilling a contract in a new ASC Subtopic 340-40, Other Assets and Deferred Costs – Contracts with Customers.

ASU 2014-09 is effective for public companies for annual periods beginning after December 15, 2016 and interim periods within those annual periods, and early adoption is not permitted. ASU 2014-09 may be applied using either a full retrospective approach, in which all years included in the financial statements are presented under the revised guidance, or a modified retrospective approach. Under the modified retrospective cumulative catch-up approach, financial statements will be prepared using the new standard for the year of adoption, but not for prior years. Under this method, entities will recognize a cumulative catch-up adjustment to the opening balance of retained earnings at the effective date for contracts that still require performance by the Company and disclose all line items in the year of adoption as if they were prepared under the old revenue guidance. The Company is currently evaluating the impact of ASC 606, but at the current time does not know what impact the new standard will have on revenue recognized and other accounting decisions in future periods, if any, nor what method of adoption will be selected if the impact is material.

In August 2014, the Financial Accounting Standards Board issued ASU No. 2014-15, Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU 2014-09”). ASU 2014-15 provides guidance on management's responsibility in evaluating whether there is substantial doubt about a company's ability to continue as a going concern and about related footnote disclosures. For each reporting period, management will be required to evaluate whether there are conditions or events that raise substantial doubt about a company's ability to continue as a going concern within one year from the date the financial statements are issued. ASU 2014-15 is effective for annual periods ending after December 15, 2016, and interim periods thereafter; earlier adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial condition, results of operations or cash flows.

Summary of Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2015

Significant Accounting Policies [Line Items]

Basis of Consolidation

Basis of Consolidation

The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Response Genetics, Ltd., a Scottish corporation (the “Subsidiary”), which was incorporated in November 2006. The Subsidiary had no employees or active operations in 2014 or to date in 2015. All significant intercompany transactions and balances have been eliminated in consolidation.

Cash and Cash Equivalents

Cash and Cash Equivalents

The Company considers all highly liquid investments with a maturity date of three months or less from the date of purchase to be cash equivalents. The carrying value of cash equivalents approximates fair value due to the short-term nature and liquidity of these instruments. The Company’s cash equivalents are comprised of cash on hand, deposits in banks and money market investments.

Accounts Receivable

Accounts Receivable

Pharmaceutical Accounts Receivable

The Company invoices its clients as specimens are processed and any other contractual obligations are met. The Company’s contracts with clients typically require payment within 45 days of the date of invoice. The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of its clients to make required payments. The Company specifically analyzes accounts receivable and historical bad debts, client credit, current economic trends and changes in client payment trends when evaluating the adequacy of the allowance for doubtful accounts. Account balances are charged-off against the allowance when it is probable the receivable will not be recovered. To date, the Company’s pharmaceutical customers have primarily been large pharmaceutical companies. As a result, bad debts from pharmaceutical accounts receivable to date have been minimal. Pharmaceutical company accounts receivable as of December 31, 2014 and March 31, 2015 were $1,037,834 and $454,773, respectively. There were no allowances for doubtful accounts recorded against these pharmaceutical accounts receivable at December 31, 2014 and March 31, 2015.

ResponseDX^® Accounts Receivable

ResponseDX^® accounts receivable are recorded from two primary payors: (1) Medicare and (2) third party payors such as commercial insurance and private payors or self-paying payors (“Private Payors”). ResponseDX^® accounts receivable are recorded at established billing rates less an estimated billing adjustment, based on reporting models utilizing historical cash collection percentages and updated for current effective reimbursement factors.  Management performs ongoing valuations of accounts receivable balances based on management’s evaluation of historical collection experience and industry trends.  Based on the historical experience for our accounts, management has determined, based on a detailed analysis, that accounts receivable associated with certain billings are unlikely to be collected. Therefore, the Company has recorded an allowance for doubtful accounts of $2,071,706 and $2,226,890 as of December 31, 2014 and March 31, 2015, respectively. The Company’s bad debt expense for the three months ended March 31, 2014 and 2015 was $1,293,850 and $1,902,144, respectively.

ResponseDX^® accounts receivable as of December 31, 2014 and March 31, 2015, consisted of the following:

 

	December 31, 2014			March 31, 2015
Net Medicare receivable	$	2,814,989		$	2,191,781
Net Private Payor receivable		6,029,300			5,639,447
		8,844,289			7,831,228
Allowance for doubtful accounts		(2,071,706	)		(2,226,890	)
Total	$	6,772,583		$	5,604,338

At December 31, 2014 and March 31, 2015, all Medicare accounts receivable outstanding for a period of greater than one year have been reserved 100%.

Property and Equipment

Property and Equipment

Property and equipment are carried at cost less accumulated depreciation and amortization. Depreciation and amortization are calculated using the straight-line methods over the estimated useful lives of the assets. The Company has determined the estimated useful lives of its property and equipment, as follows:

Laboratory equipment	5 to 7 years
Furniture and equipment	3 to 7 years
Purchased and internally-developed software	3 to 5 years
Leasehold improvements	Shorter of the useful life (5 to 7 years) or the lease term

 

Maintenance and repairs are charged to expense as incurred. The cost and accumulated depreciation of assets sold or otherwise disposed of are removed from the related accounts and the resulting gain or loss is reflected in the statements of operations. The Company has capitalized costs related to the development of database software (see Note 3). The portion of this database placed into service is amortized in accordance with ASC 350-40, Internal-Use Software. The amortization period is five years using the straight-line method.

Revenue Recognition

Revenue Recognition

Pharmaceutical Revenue

Revenues that are derived from testing services provided to pharmaceutical companies are recognized on a contract specific basis pursuant to the terms of the related agreements. Revenue is recognized in accordance with ASC 605, Revenue Recognition, which requires that four basic criteria must be met before revenue can be recognized: (1) persuasive evidence that an arrangement exists; (2) delivery has occurred and title and the risks and rewards of ownership have been transferred to the client or services have been rendered; (3) the price is fixed or determinable; and (4) collectability is reasonably assured.

Revenues are recorded on an accrual basis as the contractual obligations are completed and as a set of assays is processed through the Company’s laboratory under a specified contractual protocol and are recorded on the date the tests are completed. Certain contracts have minimum assay requirements that, if not met, result in payments that are due upon the completion of the designated period. In these cases, revenues are recognized when the end of the specified contract period is reached.

On occasion, the Company may enter into a contract that requires the client to provide an advance payment for specimens that will be processed at a later date. In these cases, the Company records this advance as deferred revenue and recognizes the revenue as the specimens are processed or at the end of the contract period, as appropriate. There was no deferred revenue at December 31, 2014 or March 31, 2015.

The Company recorded revenue from pharmaceutical clients for the three months ended March 31, 2014 and 2015 of $577,381 and $462,093, respectively.

ResponseDX^® Revenue

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.

Services are provided to certain patients covered by various third-party payer programs including various managed care organizations, commercial insurance plans and Medicare programs. Billings for services under third-party payer programs are included in revenue net of allowances for contractual discounts and allowances for differences between the amounts billed and estimated payment amounts. Significant judgment is inherent in the selection of assumptions and the interpretation of historical experience as well as the identification of external and internal factors affecting the determination of these reserves for Medicare, private health insurance companies, healthcare institutions, and patients.

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 assumptions used to determine these contractual allowances are reasonable considering known facts and circumstances. If actual future payments are less than the estimates the Company made at the time of recognizing revenue, the consolidated financial position, results of operations and cash flows may be negatively impacted. If actual future payments are materially different from the contracted amounts or estimates, the difference is accounted for as a change in estimate in the period in which they become known. Adjustments to the estimated payment amounts based on final settlement are recorded upon settlement as an adjustment to revenue.

For the three months ended March 31, 2014 and 2015, approximately 39% and 42%, respectively, of the Company's ResponseDX^® revenues were derived directly from the Medicare program. The Company’s Medicare provider number allows it to invoice and collect from Medicare. The Company’s invoicing to Medicare is primarily based on amounts allowed by Medicare for the service provided as defined by Common Procedural Terminology (“CPT”). Laws and regulations governing the Medicare program and healthcare generally are complex and subject to interpretation.

The following details ResponseDX^® revenue for the periods indicated:

	Three Months
	Ended March 31,
	2014		2015
Net Medicare revenue	$	1,308,422	$	1,408,241
Net Private Payor revenue		2,009,131		1,920,270
Net ResponseDX® revenue	$	3,317,553	$	3,328,511

The Company recognizes revenue for services covered by Medicare based on the Medicare fee schedule. For 2014, the Company’s Medicare fees were based on the Centers for Medicare and Medicaid Services (“CMS”) proposed “Medicare Program; Revisions to Payment Policies under the Physician Fee Schedule, Clinical Laboratory Fee Schedule & Other Revisions to Part B for CY 2014” released in July 2013. For the three months ended March 31, 2015, the Company’s fees were based on the Centers for Medicare and Medicaid Services (“CMS”) fee schedules released in December 2014.

The Company updates its estimates of Medicare fees based on current information from CMS. The nature of the testing services the Company provides, the evidence the Company gathers to establish the creditworthiness of its payors and the delivery method of its services have not changed from prior periods, and therefore these assumption remain appropriate.

Cost of Revenue

Cost of Revenue

Cost of revenue represents the cost of materials, direct labor, royalties, costs associated with processing tissue specimens including pathological review, staining, microdissection, paraffin extraction, reverse transcription polymerase chain reaction (“PCR”), fluorescence in situ hybridization (“FISH”), quality control analyses, license fees and delivery charges necessary to render an individualized test result. Costs associated with performing tests are recorded as the tests are processed.

License Fees

License Fees

The Company has licensed technology for the extraction of ribonucleic acid (“RNA”) from formalin-fixed, paraffin-embedded tumor specimens from the University of Southern California (“USC”). Under the terms of the license agreement, the Company is required to pay royalties to USC calculated as a fixed percentage of the net sales price as defined in the agreement that the Company generates by using this technology. Total license fees expensed in cost of revenue under the license agreement with USC were $10,961 and $5,508 for the three months ended March 31, 2014 and 2015, respectively. The Company also maintains a non-exclusive license to use certain patents related to the PCR of Roche Molecular Systems, Inc. (“Roche”). The Company pays Roche a royalty fee based on revenue that the Company generates through use of this technology. The Company accrues for such royalties at the time revenue is recognized. Royalties expensed in cost of revenue under the Roche agreement totaled $44,373 and $16,265 for the three months ended March 31, 2014 and 2015, respectively. Such royalties are included in cost of revenues in the accompanying statements of operations.

The Company is subject to potentially significant variations in royalties recorded in any period. While the amount paid is based on a fixed percentage of net sales price as defined in the agreement of specific tests pursuant to terms set forth in the agreements with USC and Roche, the amount due is calculated based on the revenue we recognize using the respective licensed technology. As discussed above, this revenue can vary from period to period as it is dependent on the timing of the specimens submitted by our clients for testing.

Additionally, the Company periodically analyzes the technical procedures performed in its test offerings to assess which activities utilize licensed technologies and to calculate royalties for use of the licensed technology. The most recent analyses indicate that the Company could owe less than the amounts that have been accrued for royalties payable. Roche is still reviewing the Company’s updated royalty calculations. It is possible that based on Roche’s review and the Company’s discussions with Roche, the Company may further adjust its Roche royalty accrual.

Research and Development

Research and Development

The Company expenses costs associated with research and development activities as incurred. Research and development costs are expensed as incurred and classified as research and development costs. Research and development costs include employee costs (salaries, payroll taxes, benefits, and travel), equipment depreciation and maintenance, laboratory supplies, primers and probes, reagents, patent costs and occupancy costs.

Line of Credit

Line of Credit

On July 14, 2011, the Company entered into a line of credit agreement with Silicon Valley Bank (the “Bank”), which agreement has been amended most recently on July 30, 2014. The line of credit is collateralized by all of the Company’s assets including its pharmaceutical, Private Payor and Medicare receivables. The maximum amount that can be borrowed from the line of credit is $2,000,000, subject to certain conditions. As of December 31, 2014 and March 31, 2015, the Company had drawn $1,500,000 and $1,465,662, respectively, against the line of credit. As of December 31, 2014 and March 31, 2015, the available amount the Company can draw from the line of credit was $500,000 and $463,677, respectively, calculated as the lesser of (i) the Company’s calculated borrowing base, which was 80% of certain of the Company’s accounts receivable, or (ii) the amount available under the line of credit. During the first half of 2014, the interest rate charged to the Company on the line of credit was 5%, calculated by reference to the prime rate plus 1.75%. For the latter half of 2014 and the three months ended March 31, 2015, the rate charged to the Company was 5.5%, calculated by reference to the prime rate plus 2.25%. The line of credit’s maturity date is July 25, 2016.

The line of credit is subject to various covenants, including financial covenants that require the Company to maintain (i) an adjusted quick ratio of at least 1.25 to 1.00; (ii) quarterly rolling twelve-month net revenue balances beginning December 31, 2014; and (iii) quarterly minimum liquidity of $1,000,000. The Company’s revenue covenant and liquidity covenant under the line of credit agreement conform with, and are cross-defaulted with equivalent covenants under the SWK Credit Agreement (as described below.) At December 31, 2014 and March 31, 2015, the Company was in compliance with its covenants under the line of credit agreement. Historically, however, the Company has been out of compliance with certain covenants from time to time, and the Company has received waivers and forbearance agreements from the Bank.

From time to time, the Company’s calculated borrowing base under its Bank line of credit may decrease to a level where the Company is in an over-advance position in which case the Company will be required to repay any outstanding amounts greater than the calculated borrowing base for such covered period back to the Bank immediately. The Company will be able to draw down on the credit line again with respect to such paid-back amount once the Company is in compliance with the borrowing base requirement.

As of December 31, 2014 and March 31, 2015, the line of credit under the credit agreement was classified as a non-current liability of the Company on the accompanying condensed consolidated balance sheet as the line of credit had a maturity date of greater than one year from the date of the balance sheet.

SWK Term Loan

SWK Term Loan

On July 30, 2014 (the “Closing Date”), the Company entered into a credit agreement (the “SWK Credit Agreement”) with SWK Funding LLC, as the administrative agent (the “Agent” or “SWK”), and the lenders (including SWK) party thereto from time to time (the “Lenders”). The SWK Credit Agreement provides for a multi-draw term loan to the Company (the “Loan”) up to a maximum principal amount of $12,000,000 (the “Loan Commitment Amount”). On the Closing Date, the Lenders advanced the Company an amount equal to $8,500,000 which is due and payable on July 30, 2020 (the “Term Loan Maturity Date”) or such earlier date on which the Loan Commitment Amount is terminated pursuant to the terms of the SWK Credit Agreement. On February 3, 2015 (the “Amendment Closing Date”), the Company and SWK entered into a first amendment (the “Amendment”) to the SWK Credit Agreement.  Pursuant to the Amendment, the Company drew an additional $1,500,000 of the Loan Commitment Amount thereby increasing the total amount advanced to the Company under the SWK Credit Agreement to $10,000,000.

The Loan bears interest at a rate equal to the LIBOR Rate (as defined in the SWK Credit Agreement) plus an applicable margin of 12.5% per annum, subject to a one percent (1.0%) LIBOR floor. Interest on the Loan is due and payable in arrears (i) on the forty-fifth (45th) day following the last calendar day of each of the months of September, December, March, and June, commencing on November 15, 2014, (ii) upon a prepayment of the Loan and (iii) on the Term Loan Maturity Date. At December 31, 2014 and March 31, 2015, the interest rate charged to the Company was 13.5%. Upon the earlier of (a) the Term Loan Maturity Date or (b) full repayment of the Loan, the Company is also required to pay an exit fee. On September 9, 2014, SWK, in its capacity as the initial Lender, assigned part of its interests under the SWK Credit Agreement to SG-Financial, LLC (“SG”). Pursuant to the assignment, SG was assigned $2,500,000 of the $8,500,000 Closing Date initial advance to the Company and $1,029,412 of the subsequent term loan commitment. On January 30, 2015, SG assigned all of its interests under the SWK Credit Agreement back to SWK.

On the Closing Date, the Company issued to the Agent a warrant (the “Initial Warrant”) to purchase up to 681,090 shares of the Company's common stock. The Initial Warrant was exercisable, in whole or in part, from the date of issuance until and including July 30, 2020 at an exercise price of $0.936 per share, subject to adjustment. The Initial Warrant was valued at $414,239, or approximately $0.61 per covered share, using a Black-Scholes pricing model with the following assumptions: 2.01% risk free rate, 0% dividend, 101.5% volatility, and six-year expected life. The value of the warrant was recorded on the balance sheet included in additional paid-in capital. On September 9, 2014, the Agent assigned a portion of the Initial Warrant consisting of the right to purchase 200,321 shares of common stock to SG (the “SG Initial Warrant”). On January 30, 2015, SG assigned the SG Initial Warrant back to the Agent and on the Amendment Closing Date, the Company replaced the Initial Warrant to purchase the total 681,090 shares of the Company’s common stock with a new warrant with an adjusted exercise price (the “Replacement Warrant”).   The Replacement Warrant is exercisable up to and including July 30, 2020 at an exercise price of $0.39 per share.  The Agent may exercise the Replacement Warrant on a cashless basis at any time.  In the event the Agent exercises the Replacement Warrant on a cashless basis, the Company will not receive any proceeds.  The exercise price of the Replacement Warrant is subject to customary adjustments for stock splits, stock dividends, recapitalizations and the like.

For accounting purposes, the proceeds received in the July 2014 transaction were allocated to the liability for debt, a debt issuance discount and additional paid-in capital for the warrant based upon the relative fair value of the loan and the warrant. The amounts recorded in the financial statements were $8,500,000 for loan liability, $576,161 for debt issuance discount and $377,140 to additional paid-in capital for the warrant. Additionally, the Company recorded deferred loan issuance costs of $187,092 for investment banker fees and legal fees incurred to enter into the SWK Credit Agreement. The debt issuance discount and the deferred issuance costs are being amortized to interest expense over the six-year term of the loan. Upon the re-issuance of the Replacement Warrant on February 3, 2015 at a reduced exercise price of $0.39, the debt issuance discount was re-valued at $599,305 and a $23,144 increase in the warrant value was recorded as an increase to debt discount and additional paid-in capital. The Replacement Warrant transaction was determined to be a debt modification.

In addition, on the Amendment Closing Date, the Company issued the Agent a new warrant (the “First Amendment Warrant”) to purchase 576,923 shares of Common Stock.  The First Amendment Warrant is exercisable up to and including February 3, 2021 at an exercise price of $0.39 per share, subject to adjustment.  The First Amendment Warrant was valued at $167,712, or approximately $0.29 per covered share, using a Black-Scholes pricing model with the following assumptions: 1.39% risk free rate, 0% dividend, 90.9% volatility and six-year expected life. The value of the warrant was recorded on the balance sheet included in additional paid-in capital. The Agent may exercise the First Amendment Warrant on a cashless basis at any time.  In the event the Agent exercises the First Amendment Warrant on a cashless basis, the Company will not receive any proceeds.  The exercise price of the First Amendment Warrant is subject to customary adjustments for stock splits, stock dividends, recapitalizations and the like.

Additionally, for accounting purposes, the proceeds received in the February 2015 transaction were allocated to the liability for debt, a debt issuance discount and additional paid-in capital for the warrant based upon the relative fair value of the loan and the warrant. The amounts recorded in the financial statements were $1,500,000 for loan liability, $168,372 for debt issuance discount and $148,887 to additional paid-in capital for the warrant. Additionally, the Company recorded deferred loan issuance costs of $19,485 for investment banker fees and legal fees incurred to enter into the Amendment. The debt issuance discount and the deferred issuance costs are being amortized to interest expense over the six-year term of the loan.

The Company may prepay the Loan, in whole or in part, upon five business days’ written notice provided that a prepayment premium is paid to the Lenders as set forth in the SWK Credit Agreement. The Company is required to prepay the Loan with any net cash proceeds received from certain types of dispositions of assets described in the SWK Credit Agreement. The Company is also required to make certain revenue-based payments on the Company’s quarterly revenues, applied in the following priority: (i) first, to the payment of all fees, costs, expenses and indemnities due and owing to the Agent under the SWK Credit Agreement, (ii) second, to the payment of all fees, costs, expenses and indemnities due and owing to the Lenders under the SWK Credit Agreement, (iii) third, to the payment of all accrued but unpaid interest until paid in full, (iv) fourth, for each revenue-based payment date after August 2016, to the payment of all principal of the Loan up to an aggregate amount of $750,000 on any such payment date and (v) fifth, all remaining amounts to the Company.

As of December 31, 2014 and March 31, 2015, the term debt under SWK Credit Agreement was classified as a non-current liability of the Company on the accompanying balance sheet as the repayment terms are based on future revenues that cannot be reasonably estimated and therefore all outstanding amounts are classified as non-current.

The SWK Credit Agreement contains customary affirmative and negative covenants for credit facilities of its type, including covenants that limit the Company’s ability to pay dividends or redeem outstanding equity interests, incur additional indebtedness, grant additional liens, engage in any other type of business, make investments, merge, consolidate or sell all or substantially all of its assets and enter into transactions with related parties. The SWK Credit Agreement also contains certain financial covenants, including certain minimum aggregate revenue requirements. The Company was in compliance with these covenants at December 31, 2014 and March 31, 2015.

The SWK Credit Agreement includes customary events of default, including failure to pay principal, interest or fees when due, failure to comply with covenants, default under certain other indebtedness, certain insolvency or bankruptcy events, the occurrence of certain material judgments, the institution of any proceeding by a government agency or a change of control of the Company that is not otherwise permitted under the SWK Credit Agreement.

Refer to Note 11 to these unaudited condensed consolidated financial statements for a description of the second amendment to the SWK Credit Agreement, dated April 3, 2015, pursuant to which the Company drew the remaining $2,000,000 of the Loan Commitment Amount and issued certain of the Lenders warrants to purchase an aggregate 2,702,702 shares of Common Stock.

Income Taxes

Income Taxes

Deferred tax assets and liabilities are determined based on differences between the financial reporting and tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Valuation allowances are established when necessary to reduce deferred tax assets to the amount expected to be realized.

ASC 740, Income Taxes, clarifies the accounting for uncertainty in income taxes recognized in financial statements and requires the impact of a tax position to be recognized in the financial statements if that position is more likely than not of being sustained by the taxing authority. As of December 31, 2014 and March 31, 2015, the Company does not have a liability for unrecognized tax benefits. The Company recognizes interest and penalties associated with tax matters as part of the income tax provision, and includes accrued interest and penalties with the related tax liability in the balance sheet. For the periods ended March 31, 2014 and 2015, there were no interest and penalties recorded in the Condensed Consolidated Statement of Operations.

Stock-Based Compensation

Stock-Based Compensation

The Company accounts for stock-based compensation in accordance with ASC 718, Stock Compensation, Share-Based Payment. Stock-based compensation expense for all stock-based compensation awards granted is based on the grant-date fair value estimated in accordance with the provisions of ASC 718. The Company recognizes these compensation costs on a straight-line basis over the requisite service period of the award, which is generally the option vesting period. As further described in Note 7, certain awards granted to Thomas A. Bologna, the Company’s Chairman and Chief Executive Officer, were recognized based on an accelerated vesting basis triggered by market conditions rather than a straight-line basis.

The Company accounts for equity instruments issued to non-employees in accordance with ASC 505, Equity. Under ASC 505, stock option awards issued to non-employees are measured at fair value using the Black-Scholes option-pricing model and recognized pursuant to a performance model.

Management Estimates

Management Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant estimates in these condensed consolidated financial statements have been made for revenue, allowances for doubtful accounts, impairment of long-lived assets, depreciation of property and equipment and stock-based compensation. Actual results could differ materially from those estimates.

Long-lived Assets

Long-lived Assets

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company evaluates potential impairment by comparing the carrying amount of the asset with the estimated undiscounted future cash flows associated with the use of the asset and its eventual disposition. Should the review indicate that the assets cost is not recoverable, the carrying value of the asset would be reduced to its fair value, which is measured by future discounted cash flows.

Foreign Currency Translation

Foreign Currency Translation

The financial position and results of operations of the Company’s foreign subsidiary are determined using local currency as the functional currency. Assets and liabilities of these operations are translated at the exchange rate in effect at each period-end. Statement of Operations amounts are translated at the average rate of exchange prevailing during the period. Translation adjustments arising from the use of differing exchange rates from period to period are included in accumulated other comprehensive loss in stockholders’ deficit.

Comprehensive Loss

Comprehensive Loss

The components of comprehensive loss are accumulated net loss and foreign currency translation adjustments for the three months ended March 31, 2014 and 2015.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

Cash and cash equivalents are stated at cost, which approximates fair market value.  Cash equivalents consist of money market accounts, with fair values estimated based on quoted market prices. Debt balances are stated at historical amounts less principal payments, which approximate fair market value. The Company believes interest rates in its debt agreements are commensurate with lender risk profiles for similar companies.

Advertising Costs

Advertising Costs

The Company markets its services through its advertising activities in trade publications and on the internet. Advertising costs are included in selling and marketing expenses on the statements of operations and are expensed as incurred. Advertising costs for the three months ended March 31, 2014 and 2015 were $6,422 and $17,124, respectively. 

Concentration of Credit Risk and Clients and Limited Suppliers

Concentration of Credit Risk and Clients and Limited Suppliers

Cash and cash equivalents are maintained at financial institutions and, at times, balances may exceed federally insured limits. The Company has never experienced any losses related to these balances. At March 31, 2015, the Company had $1,476,222 in cash and cash equivalents that exceeded federally insured limits. At March 31, 2015, $7,803 of cash was held outside of the United States.

Many of the supplies and reagents used in the Company’s testing process are procured from a limited number of suppliers. Any supply interruption or an increase in demand beyond the suppliers’ capabilities could have an adverse impact on the Company’s business. Management believes it can identify alternative sources, if necessary, but it is possible such sources may not be identified in sufficient time to avoid an adverse impact on its business. The Company purchases certain laboratory supplies and reagents primarily from a limited number of suppliers. The Company made approximately 73% of its reagent purchases from four suppliers during the year ended December 31, 2014 and made approximately 70% of its reagent purchases from three suppliers during the three months ended March 31, 2015.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In April 2015, the FASB issued ASU 2015-03 “Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.” ASU 2015-03 requires an entity to present debt issuance costs related to a recognized debt liability in the balance sheet as a direct deduction from the carrying amount of the debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this update. The amendment will be effective for the Company’s annual and interim reporting periods beginning January 1, 2016 and should applied on a retrospective basis. The adoption of ASU 2015-03 will not have any impact on the Company’s results of operations, but will result in debt issuance costs being presented as a direct reduction from the carrying amount of debt liabilities.  This standard will not have a material impact on the Company’s consolidated financial statements.

In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which modifies how all entities recognize revenue, and consolidates into one Accounting Standards Codification ("ASC") Topic (ASC Topic 606, Revenue from Contracts with Customers) the current guidance found in ASC Topic 605, Revenue Recognition, and various other revenue accounting standards for specialized transactions and industries. The core principle of the guidance is that “an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” In achieving this objective, an entity must perform five steps: (1) identify the contract(s) with a customer, (2) identify the performance obligations of the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 also clarifies how an entity should account for costs of obtaining or fulfilling a contract in a new ASC Subtopic 340-40, Other Assets and Deferred Costs – Contracts with Customers.

ASU 2014-09 is effective for public companies for annual periods beginning after December 15, 2016 and interim periods within those annual periods, and early adoption is not permitted. ASU 2014-09 may be applied using either a full retrospective approach, in which all years included in the financial statements are presented under the revised guidance, or a modified retrospective approach. Under the modified retrospective cumulative catch-up approach, financial statements will be prepared using the new standard for the year of adoption, but not for prior years. Under this method, entities will recognize a cumulative catch-up adjustment to the opening balance of retained earnings at the effective date for contracts that still require performance by the Company and disclose all line items in the year of adoption as if they were prepared under the old revenue guidance. The Company is currently evaluating the impact of ASC 606, but at the current time does not know what impact the new standard will have on revenue recognized and other accounting decisions in future periods, if any, nor what method of adoption will be selected if the impact is material.

In August 2014, the Financial Accounting Standards Board issued ASU No. 2014-15, Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (“ASU 2014-09”). ASU 2014-15 provides guidance on management's responsibility in evaluating whether there is substantial doubt about a company's ability to continue as a going concern and about related footnote disclosures. For each reporting period, management will be required to evaluate whether there are conditions or events that raise substantial doubt about a company's ability to continue as a going concern within one year from the date the financial statements are issued. ASU 2014-15 is effective for annual periods ending after December 15, 2016, and interim periods thereafter; earlier adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial condition, results of operations or cash flows.

Stock Options, Restricted Stock and Warrants

7. Stock Options, Restricted Stock and Warrants

In March 2000, the Company adopted a Stock Option Plan (the “2000 Stock Plan”) as approved by its Board of Directors. Under the 2000 Stock Plan, the Company granted options to acquire up to 1,600,000 shares of common stock. In connection with the adoption of the 2006 Employee, Director and Consultant Stock Plan, as further discussed below, the Company is to grant no additional options under the 2000 Stock Plan. Under the 2000 Stock Plan, there were no options to purchase shares of the Company’s common stock that remained outstanding as of December 31, 2013. Prior to March 2007, the Company also granted options to purchase 16,000 shares of common stock to two consultants which were granted under separate agreements outside of the 2000 Stock Plan.

On October 26, 2006, the Board of Directors of the Company approved, and on May 1, 2007, reapproved the adoption of the 2006 Employee, Director and Consultant Stock Plan (the “2006 Stock Plan”). The stockholders approved the 2006 Stock Plan on June 1, 2007. The initial number of shares which may be issued from time to time pursuant to the 2006 Stock Plan was 2,160,000 shares of common stock. Also, the 2006 Stock Plan includes the number of shares subject to purchase under options issued under the 2000 Stock Plan, where the options expired on or after October 18, 2006, subject to a maximum of 210,000 additional options.  In addition, on the first day of each fiscal year of the Company during the period beginning in fiscal year 2008 and ending on the second day of fiscal year 2017, the number of shares that may be issued from time to time pursuant to the 2006 Stock Plan is increased by the lesser of (i) 200,000 shares or equivalent, after determination of the effect of any stock split, stock dividend, combination or similar transactions as set forth in the 2006 Stock Plan, (ii) 5% of the number of outstanding shares of common stock of the Company on such date or (iii) an amount determined by the Board of Directors of the Company.  The initial number of shares available for issuance of 2,160,000 increased by 210,000 for options issued under the 2000 Stock Plan expiring after October 2006 and by 200,000 in 2008 through 2015, resulting in the total number of shares that may be issued as of January 1, 2015 to be 3,970,000. As of March 31, 2015, there were 1,508,922 options available for grant under the 2006 Stock Plan.

Employee options vest according to the terms of the specific grant and expire 10 years from the date of grant. Non-employee option grants to date typically vest over a two- to three-year period. The Company had 2,461,078 options outstanding at a weighted average exercise price of $1.59 at March 31, 2015. There were 1,027,992 non-vested stock options outstanding with a weighted average exercise price of $1.07 at March 31, 2015. As of March 31, 2015, there was $637,950 of total unrecognized compensation cost related to non-vested share-based compensation arrangements granted under the 2006 Stock Plan. That cost is expected to be recognized over a weighted-average period of 2.4 years.

Except for certain grants of restricted common stock and common stock options containing market conditions as described below, the Company estimated share-based compensation expense for the three months ended March 31, 2015* using the Black-Scholes model with the following weighted average assumptions:

	Three Months Ended March 31, 2015
Risk free interest rate		1.68	%
Expected dividend yield		—	%
Expected volatility		99.2	%
Expected term **(in years)		6.25
Forfeiture rate ***		7.0	%

*     There were no stock options issued for the three months ended March 31, 2014.

** Expected term is calculated using SAB 107, Simplified Formula. Management has concluded that the use of the simplified method for calculating the expected term of its common stock option grants is appropriate given the lack of historical exercises and the standard terms of the employee option grants, including, options are granted at-the-money, exercise is conditional only on performing service through the vesting dates, termination of service causes forfeiture of options, employees have a limited number of days to exercise options after termination of service, and options are non-transferable.

*** Forfeiture range represents 0% for directors and 21% for employees.

The following table summarizes the stock option activity for the 2006 Plan for the three months ended March 31, 2015:

	Number of Shares		Weighted Average Exercise Price		Remaining Contractual Life (Years)		Aggregate Intrinsic Value
Outstanding, December 31, 2014		2,833,604	$	1.62		7.9	$	-
Granted (Unaudited)		15,000	$	0.43		10.0	$	150
Exercised (Unaudited)		-	$	-		-		-
Expired (Unaudited)		(177,566)		2.86		4.9		—

Outstanding, March 31, 2015 (Unaudited)		2,461,078	$	1.56		7.8	$	150
Exercisable, March 31, 2015 (Unaudited)		1,433,086	$	1.91		7.0	$	—

The weighted-average grant-date fair value of options granted during the year ended December 31, 2014 was $0.70. The weighted-average grant-date fair value of options granted during the three months ended March 31, 2015 was $0.43. The aggregate intrinsic value of outstanding options at December 31, 2014 and the options exercised during 2014 were $-0- and $7,605, respectively, which represents options whose exercise price was less than the closing fair market value of the Company’s common stock on December 31, 2014 of $0.32. No options were exercised during the three months ended March 31, 2015.

The following table provides additional information regarding options outstanding under the 2006 Plan as of March 31, 2015 (unaudited):

	Options Outstanding				Options Exercisable
Exercise Price	Number of Options		WA Remaining Contractual Term		Number of Options		WA Remaining Contractual Term

License and Collaborative Agreements

6. License and Collaborative Agreements

License Agreement with the University of Southern California (“USC”)

In April 2000, as amended in June 2002 and April 2005, the Company entered into a license agreement with USC. Under this agreement, USC granted the Company a worldwide, exclusive license with the right to sublicense, the patents for nucleic acid extraction methodologies (“RGI-1”) and related technology, for use in human and veterinary diagnostic laboratory services, the sale of clinical diagnostic products, and the sale of research products to the research community. USC retains the right under the agreement to use the technology for research and educational purposes.

In consideration for this license, the Company agreed to pay USC royalties based on a percentage of net sales of products or services that make use of RGI-1 and related technology and to meet a certain minimum in royalty payments. Royalty expense relating to this agreement amounted to $10,961 and $5,508 for the three months ended March 31, 2014 and 2015, respectively. Changes to estimates of factors impacting the accrued royalty liability could result in adjustments in future periods. Such expense is included in cost of revenue in the accompanying unaudited consolidated statements of operations.

License Agreement with Roche Molecular Systems (“Roche”)

In November 2004, the Company entered into a non-exclusive license to use Roche’s technology including specified nucleic acid amplification processes (“PCR Processes”) to perform certain human invitro clinical laboratory services. In consideration for this license, the Company is obligated to pay royalties to Roche, based on a percentage of net sales of products or services that make use of the PCR Processes. Royalty expense included in cost of revenue relating to this agreement amounted to $44,373 and $16,265 for the three months ended March 31, 2014 and 2015, respectively.

In November 2004, the Company also entered into an agreement with Roche, pursuant to which the Company is collaborating with Roche to produce commercially viable assays used in the validation of genetic markers for pharmaceutical companies. Specifically, the Company has licensed the rights to Roche to use the pre-diagnostic assays the Company develops in the course of using its RNA-extraction technologies to provide testing services to pharmaceutical companies and to produce diagnostic kits that then can be sold commercially to those pharmaceutical companies. Roche is required to pay the Company royalties of a certain percentage of net sales of such diagnostic kits sold to pharmaceutical companies. Through March 31, 2015, Roche has not been required to pay any royalties to the Company pursuant to this agreement.

Services Agreement with GlaxoSmithKline, LLC formerly known as SmithKline Beecham Corporation (d.b.a. GlaxoSmithKline or “GSK”)

In January 2006, the Company entered into a master services agreement with GSK, a leading pharmaceutical manufacturer, pursuant to which the Company provides services in connection with profiling the expression of various genes from a range of human cancers. Under the agreement, the Company provides GSK with testing services as described in individual protocols and GSK pays the Company for such services based on the pricing schedule established for each particular protocol. GSK was obligated to make minimum annual payments to the Company under the agreement and also was obligated to make a non-refundable upfront payment to the Company, to be credited against work undertaken pursuant to the agreement.

In December 2008, the Company amended and restated its master services agreement with GSK and extended the term of the agreement for a two-year period, with the option for the parties to extend the agreement for additional one-year periods at the end of the term, upon their mutual written agreement. In addition, the Company became a preferred provider to GSK and its affiliates of genetic testing services on a fee-for-service basis and, in anticipation of the services to be provided, GSK agreed to make a non-refundable upfront payment.

The Company recognized revenue of $-0- and $2,046 relating to the GSK agreement for the three months ended March 31, 2014 and 2015, respectively.

Master Services Agreement with GlaxoSmithKline Biologicals S.A. (“GSK Bio”)

On July 26, 2012, the Company entered into a second amended and restated master services agreement with GSK Bio, the vaccine division of GSK. The agreement, which was effective as of May 15, 2012, was amended on December 17, 2014 to extend the term to December 31, 2015. Pursuant to this agreement, as amended, the Company provides testing services for clinical trials and epidemiology studies relating to GSK Bio’s cancer immunotherapies. The Company performs these testing services on a fee-for-service basis as embodied in written task orders. GSK Bio retains the intellectual property rights to inventions, improvements and data resulting from the services performed under the agreement. The Company retains all intellectual property rights to its testing services and proprietary processes. All intellectual property owned by either party on the date of the agreement remains the exclusive property of the owning party.

The agreement will provides that any outstanding task orders at the time of termination will not thereby terminate (unless otherwise agreed in writing by the parties), and any such task orders will continue for the respective terms specified in such task orders (and the parties shall continue to perform their obligations thereunder). GSK Bio may terminate the agreement, without cause, upon 90 days’ written notice to the Company. The Company may terminate the agreement, without cause, upon one year’s written notice to GSK Bio. The agreement may also be terminated early if either party enters bankruptcy or similar proceedings or in the event of a material breach. GSK Bio may terminate the agreement immediately if the Company experiences a “change of control,” as defined in the agreement.

The agreement also provides for mutual indemnification by the parties and contains customary representations, warranties and covenants, including covenants governing the parties’ use of confidential information and representations regarding adequate insurance coverage or self-insurance.

The Company recognized revenue of $328,281 and $341,462 relating to the services performed for GSK Bio for the three months ended March 31, 2014 and 2015, respectively.

ASC 820, Fair Value Measurements and Disclosures, defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. ASC 820 provides guidance on how to measure fair value by providing a fair value hierarchy used to classify the source of the information. ASC 820 establishes a three-level valuation hierarchy of valuation techniques that is based on observable and unobservable inputs. Classification within the hierarchy is determined based on the lowest level of input that is significant to the fair value measurement. The first two inputs are considered observable and the last unobservable, that may be used to measure fair value and include the following:

Level 1 - Quoted prices in active markets for identical assets or liabilities.

Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

As of December 31, 2014 and March 31, 2015, the Company did not hold any assets that are required to be measured at fair value on a recurring basis.

Income Tax Disclosure [Abstract]

Income Taxes

8. Income Taxes

Deferred income taxes result from temporary differences between income tax and financial reporting computed at the effective income tax rate. The Company has established a valuation allowance against its net deferred tax asset due to the uncertainty surrounding the realization of such asset. Management periodically evaluates the recoverability of the deferred tax assets. At such time it is determined that it is more likely than not that deferred tax assets are realizable, the valuation allowance will be reduced.

The Company files U.S. federal, U.S. state, and foreign tax returns. The Company’s major tax jurisdictions are U.S. federal and the State of California. The Company is subject to tax examinations for the open years from 2004 through 2014.

Second Amendment to the SWK Credit Agreement

 

On April 3, 2015 (the “Second Amendment Closing Date”), the Company entered into a second amendment (the “Second Amendment”) to the SWK Credit Agreement.  Pursuant to the Second Amendment, the Company drew the remaining $2,000,000 of the Loan Commitment Amount, thereby  increasing the total amount advanced to the Company under the SWK Credit Agreement to $12,000,000. The maturity date for the term loan under the SWK Credit Agreement remains July 30, 2020, or such earlier date on which the Loan Commitment Amount is terminated, pursuant to the terms of the SWK Credit Agreement.

In addition, on the Second Amendment Closing Date, the Company issued warrants to purchase an aggregate of 2,702,702 shares of Common Stock (the “Second Amendment Warrants”) to the Lenders advancing the term loan to the Company on the Second Amendment Closing Date. The Second Amendment Warrants are exercisable up to and including April 3, 2021 at an exercise price of $0.37 per share, subject to adjustment.  A Lender may exercise its Second Amendment Warrant on a cashless basis at any time.  In the event a Lender exercises its Second Amendment Warrants on a cashless basis, the Company will not receive any proceeds.  The exercise price of the Second Amendment Warrants is subject to customary adjustments for stock splits, stock dividends, recapitalizations and the like.

Management has concluded that the use of the simplified method for calculating the expected term of its common stock option grants is appropriate given the lack of historical exercises and the standard terms of the employee option grants, including, options are granted at-the-money, exercise is conditional only on performing service through the vesting dates, termination of service causes forfeiture of options, employees have a limited number of days to exercise options after termination of service, and options are non-transferable.

Guarantees

The Company enters into indemnification provisions under its agreements with other counterparties in its ordinary course of business, typically with business partners, clients and landlords. Under these provisions, the Company generally indemnifies and holds harmless the indemnified party for losses suffered or incurred by the indemnified party as a result of the Company's activities. These indemnification provisions generally survive termination of the underlying agreement. The Company reviews its exposure under these agreements no less than annually, or more frequently when events require. The Company believes the estimated fair value of these agreements is minimal as, historically, no payments have been made by the Company under these indemnification obligations. Accordingly, the Company has no liabilities recorded for these agreements as of December 31, 2014 and March 31, 2015.

Legal Matters

The Company is, from time to time, involved in legal proceedings, regulatory actions, claims and litigation arising in the ordinary course of business. Reserves are established for specific liabilities in connection with legal actions when they can be deemed probable and estimable. These matters are not expected to have a material adverse effect upon the Company’s financial condition.

Employment Agreements

The Company has employment contracts with several individuals, which provide for annual base salaries and potential bonuses. These contracts contain certain change of control, termination and severance clauses that require the Company to make payments to certain of these employees if certain events occur as defined in their respective contracts.
