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.

Since its inception, the Company has devoted substantial effort in developing its products and has incurred losses and negative cash flows from operations. At June 30, 2014, the Company had an accumulated deficit of $71,940,591. 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. Management believes that existing cash and cash equivalents, as well as other available resources, will be sufficient to meet the Company’s working capital requirements through the next twelve months. The Company’s ability to successfully carry out its business plan is primarily dependent upon its ability to (1) attract and retain knowledgeable employees, (2) generate significant revenues and (3) if needed, obtain capital at acceptable costs. Until the Company can generate and maintain sufficient revenue to finance its cash requirements, the Company expects to satisfy its future cash needs primarily through public or private equity offerings, strategic collaborations, the line of credit, the credit facility and other financing opportunities. However, there can be no assurance that any additional financing or strategic investments will be available on acceptable terms, if at all. If the Company is not able to secure additional funding when needed, the company have to delay, reduce the scope of or eliminate selling and marketing activities or research and development programs which may have a material adverse effect on the Company.

On July 30, 2014, the Company amended its line of credit agreement, which included extending the maturity to July 25, 2016. Also on July 30, 2014, the Company entered into a credit agreement for a maximum loan commitment of $12,000,000, of which the Company drew $8,500,000 gross proceeds. (See Note 11.)

If events or circumstances occur such that the Company does not meet its operating plan as expected, the Company will most likely be required to reduce certain discretionary spending and/or curtail operations, which could have a material adverse effect on the Company’s ability to achieve its intended business objectives. No adjustments have been made to the accompanying unaudited condensed consolidated financial statements to reflect any of the matters discussed above. The unaudited condensed consolidated financial statements have been prepared on the basis that the Company will continue as a going concern.

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, 2013 were derived from our audited financial statements as of December 31, 2013. The financial statements should be read in conjunction with the Company’s audited December 31, 2013 and 2012 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, 2014.

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 2013 or to date in 2014. 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, 2013 and June 30, 2014 were $1,892,384 and $1,060,649, respectively. There were no allowances for doubtful accounts recorded against these pharmaceutical accounts receivable at December 31, 2013 and June 30, 2014.

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 Medicare and Private Payor 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 $2,404,659 and $1,912,668 as of December 31, 2013 and June 30, 2014, respectively. The Company’s bad debt expense for the three months ended June 30, 2013 and 2014 was $349,984 and $1,367,842, respectively, and for the six months ended June 30, 2013 and 2014 was $818,451 and $2,661,693, respectively.

ResponseDX^® accounts receivable as of December 31, 2013 and June 30, 2014, consisted of the following:

	December 31, 2013			June 30, 2014
				(Unaudited)
Net Medicare receivable	$	2,422,611		$	2,574,923
Net Private Payor receivable		4,315,587			4,806,646
		6,738,198			7,381,569
Allowance for doubtful accounts		(2,404,659	)		(1,912,668	)
Total	$	4,333,539		$	5,468,901

Property and Equipment

Property and equipment are carried at cost less accumulated depreciation and amortization. Depreciation and amortization are calculated using the double declining balance and 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
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.

Intangible Assets

Intangible assets are carried at the cost to obtain them. Purchased software and internally-developed intangible assets are amortized using the straight-line method over estimated useful lives of three to five years. 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.

The Company recorded revenue from pharmaceutical clients for the three months ended June 30, 2013 and 2014 of $2,207,837 and $599,282, respectively and for the six months ended June 30, 2013 and 2014 of $4,649,531 and $1,176,663, respectively.

ResponseDX^® Revenue

Revenues that are derived from ResponseDX^® testing services are recognized in accordance with ASC 605, Revenue Recognition, which requires that four basic criteria 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. We record revenues when our tests have confirmed results, which are evidence that the services have been performed.

Revenues are recorded on an accrual basis as the contractual obligations are completed and as a set of assays is processed through our laboratory under a specified contractual protocol.

ResponseDX^® Private Payor and Medicare revenues 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. 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”).

Cost-Containment Measures

Both government and private pay sources have instituted cost-containment measures designed to limit payments made to providers of health care services, which include diagnostic test providers such as the Company, and there can be no assurance that future measures designed to limit payments made to providers will not adversely affect the Company.

Regulatory Matters

A portion of the Company’s revenues are derived from Medicare reimbursement. Laws and regulations governing Medicare programs are complex and subject to change and to interpretation, and the Company may be adversely affected by future changes in the applicable laws and regulations and governmental investigations, lawsuits or private actions which include mandatory damages, fines, penalties, criminal charges, loss or suspension of licenses and/or suspension or exclusion from Medicare and certain other governmental programs. The Company believes that it is in compliance with all applicable laws and regulations and is not aware of any pending or threatened investigations involving allegations of potential wrongdoing.

Medicare reimbursement rates are also subject to regulatory changes and government funding restrictions. In January 2013, a 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. 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. On October 1, 2013, the Centers for Medicare and Medicaid Services (“CMS”) issued fees for some, but not all, of the CPT codes used by the Company. It is uncertain if continued guidance provided to Medicare and the local MAC by impacted organizations will result in additional fee increases or additional positive coverage determinations in 2014. If, however, the current reduction in reimbursement rates is adopted as is, it may have a material adverse effect on the Company's operations.

As a result of these Current Procedural Terminology (“CPT”) code changes and Medicare price changes, 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 performed an analysis that considered our historical patterns of revenue by payor in conjunction with the fluctuations we experienced in the three and six months ended June 30, 2013 and 2014 to arrive at the revenue recorded during those periods. We believe that the changes in CPT codes and pricing that are causing confusion and erratic payment experience in the payor community will take some time to resolve. The time needed for resolution will depend upon Medicare and the local MAC releasing additional pricing changes and potentially, revisions to previously revised prices, and upon the private payor community adopting the new CPT codes and some level of revised pricing. Accordingly, our revenue recognition estimates could be materially affected in future periods as pricing and payments patterns change and develop, and we may be materially affected by future or retroactive price changes.

On July 8, 2013, CMS released a new proposed rulemaking entitled “Medicare Program; Revisions to Payment Policies under the Physician Fee Schedule, Clinical Laboratory Fee Schedule & Other Revisions to Part B for CY 2014”. This proposed rule contains a number of provisions that may adversely impact the level of reimbursement for a variety of tests for which the Company receives reimbursement from the Medicare program beginning in 2014. Among other things, CMS has proposed examining approximately 1,200 laboratory tests that appear on the Clinical Lab Fee Schedule (“CLFS”) over a period of five years to determine whether advances in technology may have reduced the cost of providing such tests and whether or not the level of reimbursement should be revised. The Company is currently performing molecular testing which is reimbursed using CPT codes that fall on the CLFS. CMS has also proposed changing the methodology used to determine reimbursement rates for the technical component of certain tests reimbursed off of the Physician Fee Schedule (“PFS”). Among other provisions, CMS has proposed limiting the Relative Value Units (“RVUs”) ascribed to the Practice Expense component of their reimbursement formula for tests performed in “Non-Facilities” (which would include most clinical laboratories like the Company) to the RVUs that have been ascribed for the same procedures under the Hospital Outpatient Prospective Payment System, or the Ambulatory Payment Classification (“APC”) system which are used to reimburse “Facilities” (such as hospitals and ambulatory surgery centers). The Company currently performs FISH testing, which may be impacted by this PFS rule change if it is enacted.

Additionally, CMS has as part of its regulatory structure the National Correct Coding Initiative (“NCCI”). Recent changes to NCCI guidance may reduce allowable quantities billed for FISH testing. These changes would lower reimbursement amounts for FISH tests, and there can be no assurance that CMS will make any modifications in the existing language of the NCCI documents.

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.

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”), 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 licenses 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 the technology. These royalties are calculated as a fixed percentage of revenue that we generate from use of the technology licensed from USC. We also maintain a non-exclusive license to use Roche Molecular Systems, Inc.’s (“Roche”) PCR, homogenous PCR, and reverse transcription PCR processes. We pay Roche a fixed percentage royalty fee for revenue that we generate through use of this technology.

The Company is subject to potentially significant variations in royalties recorded in any period. While the amount paid is based on a fixed percentage from revenues 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. However, the licensors have not reviewed the Company’s updated royalty calculations. As a result, the Company has not reduced the historical accrued liability for royalties but has adjusted the current period accrual based on the revised calculation.

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 warranties 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”) and, on July 30, 2014, subsequent to the end of the quarter, the agreement was amended by the Waiver and Sixth Amendment to Loan and Security Agreement. The line of credit is collateralized by the Company’s pharmaceutical, Private Payor and Medicare receivables. As of June 30, 2014, the amount the Company can draw from the line of credit was $2,000,000 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 credit line. As of June 30, 2014, the interest fees associated with this line of credit were set at the prime rate plus 1%. The fee for the unused portion of the facility was 0.25%. During the three and six months ended June 30, 2013 and 2014, the rate charged to the Company was 5%. As needed from time to time, the Company may draw on this line for use for general corporate purposes. As of December 31, 2013 and June 30, 2014, the Company had drawn $1,000,000 and $1,500,000, respectively, against the line of credit. The line of credit is subject to various financial covenants. At June 30, 2014, the Company was in compliance with the covenants. Historically, however, the Company has been out of compliance with the covenants from time to time, and the Company has received waivers and forbearance agreements from the Bank.

As of December 31, 2013, the line of credit under the credit agreement was classified as a non-current liability on the accompanying condensed consolidated balance sheets as the line of credit had a maturity date of March 7, 2015, which was greater than one year from the date of the balance sheet. As of June 30, 2014, the line of credit under the credit agreement was classified as a non-current liability because the Waiver and Sixth Amendment to Loan and Security Agreement extended the maturity of the facility to July 25, 2016.

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.

On July 30, 2014, in connection with entering into a credit agreement with SWK Funding LLC (both as agent and initial lender), the Company and Silicon Valley Bank entered into a Waiver and Sixth Amendment to Loan and Security Agreement (“Sixth Amendment”). The Sixth Amendment waived previous defaults under the loan agreement, modified the financial covenants, extended the maturity of the loan to July 25, 2016, modified the interest rate to the prime rate published by the Wall Street Journal plus 2.25% per annum, and implemented a pre-payment fee of $40,000. The financial covenants under the Sixth Amendment include a revenue covenant and a liquidity covenant that conform with and are cross defaulted with the revenue covenant and liquidity covenant of the SWK Credit Agreement. The Company will pay a closing fee of $10,000 for the Sixth Amendment on July 18, 2015, approximately one year from the date of the closing. For more information, see Note 11 Subsequent Events.

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, 2013 and June 30, 2014, 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 June 30, 2013 and 2014, nominal amounts of interest and penalties were 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.

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’ equity.

Comprehensive Loss

The components of comprehensive loss are accumulated net loss and unrealized foreign currency translation adjustments for the three and six months ended June 30, 2013 and 2014.

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 June 30, 2013 and 2014 were $3,324 and $19,839, respectively, and for the six months ended June 30, 2013 and 2014 were $3,324 and $26,260, respectively.

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 two suppliers. The Company made approximately 93% of its reagent purchases from four suppliers during the three months ended June 30, 2013 and made approximately 71% of its reagent purchases from two suppliers during the three months ended June 30, 2014. The Company made approximately 92% of its reagent purchases from four suppliers during the six months ended June 30, 2013 and made approximately 72% of its reagent purchases from two suppliers during the six months ended June 30, 2014.

Recent Accounting Pronouncements

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 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. We will adopt ASU 2014-09 on January 1, 2017 and are currently evaluating the impact that this adoption will have on our consolidated financial statements. At this time, the Company has not determined the transition method that will be used.

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 June 30,						Six Months Ended June 30,
	2013			2014			2013			2014

Basic and diluted loss per share	$	(0.04	)	$	(0.08	)	$	(0.06	)	$	(0.17	)

Outstanding stock options to purchase 2,465,390 and 2,210,229 shares of Common Stock of the Company for the periods ended June 30, 2013 and 2014, 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 June 30, 2013 and 2014.

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, 2013 and June 30, 2014.

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. 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 $86,908 and $10,449 for the three months ended June 30, 2013 and 2014, respectively, and $191,014 and $21,410 for the six months ended June 30, 2013 and 2014, respectively. 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 $84,362 and $113,704 for the three months ended June 30, 2013 and 2014, respectively and $174,507 and $158,077 for the six months ended June 30, 2013 and 2014, 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 June 30, 2014, 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 $2,814 and $0 relating to the GSK agreement for the three months ended June 30, 2013 and 2014, respectively, and $2,814 and $0 relating to the GSK agreement for the six months ended June 30, 2013 and 2014, 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 2014, resulting in the total number of shares that may be issued as of January 1, 2014 to be 3,770,000. As of June 30, 2014, there were 1,463,748 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 2 to 3 year period. The Company had 2,210,229 options outstanding at a weighted average exercise price of $1.85 at June 30, 2014. There were 1,135,063 non-vested stock options outstanding with a weighted average grant date fair value of $1.34 at June 30, 2014.  As of June 30, 2014, there was $844,038 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 and six months ended June 30, 2013 and 2014 using the Black-Scholes model with the following weighted average assumptions:

	Three Months Ended June 30,						Six Months Ended June 30,
	2013			2014			2013			2014
	(Unaudited)			(Unaudited)			(Unaudited)			(Unaudited)

Expected term **(in years)		6.25			—			6.25			—
Forfeiture rate		7.0	%		—	%		7.0	%		—	%

** 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 Company’s lack of history of option exercises.

The following table summarizes the stock option activity for the 2006 Plan for the six months ended June 30, 2014:

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

The weighted-average grant-date fair value of options granted during the three and six months ended June 31, 2013 was $1.39 and $1.38, respectively. The Company did not grant any options during the three months ended June 30, 2014.

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 2003 through 2013.

10. Sale of Common Stock

September 2012 Private Placement

On September 13, 2012, the Company entered into a purchase agreement (the “Purchase Agreement”) with Glaxo Group Limited, an affiliate of GSK (the “GSK Investor”) and two existing investors, Swiftcurrent Partners, L.P. and Swiftcurrent Offshore, Ltd. (collectively with the GSK Investor, the “September Investors”) for the private placement of an aggregate of 8,000,000 newly-issued shares of the Company’s common stock (the “September Shares”) at a purchase price of $1.10 per share (the “September 2012 Private Placement”). The Company raised gross cash proceeds of $8,800,000 in the September 2012 Private Placement, which closed on September 13, 2012 (the “Closing”).

Pursuant to the Purchase Agreement, for so long as the GSK Investor or its affiliates own at least 50% of the September Shares it purchased pursuant to the Purchase Agreement, the GSK Investor has the right to designate one non-voting board observer (the "Board Observer"). The Board Observer, if appointed, has the right to attend all meetings of the Board of Directors of the Company and to receive all board meeting materials, subject to certain restrictions set forth in the Purchase Agreement. As of the date hereof, the GSK Investor has not exercised its right to designate the Board Observer.

In connection with the September 2012 Private Placement, the Company also entered into a registration rights agreement, dated September 13, 2012 (the “September Registration Rights Agreement”), with the September Investors pursuant to which the Company agreed to file, within 45 days of the Closing, a registration statement with the SEC to register the September Shares for resale, which registration statement was required to become effective within 180 days following the Closing. The Company also granted the September Investors certain “piggyback” registration rights, which are triggered if the Company proposes to file a registration statement for its own account or the account of one or more stockholders until the earlier of the sale of all of the September Shares or the September Shares becoming eligible for sale under Rule 144(b)(1) without restriction.

10. Sale of Common Stock – (continued)

Under the September Registration Rights Agreement, the Company is obligated to use commercially reasonable efforts to cause a registration statement to become effective and to remain continuously effective and to maintain the listing of the covered common stock on NASDAQ or other exchanges, as defined, for a period that will terminate upon the earlier of (i) the date on which all Registrable Securities covered by such Registration Statement as amended from time to time, have been sold, (ii) the date on which there are no longer any Registrable Securities outstanding or (iii) three years from the date of filing of such Registration Statement (the “Effectiveness Period”) and advise each September Investor in writing when the Effectiveness Period has expired. “Registrable Securities” means (i) the September Shares and (ii) shares of capital stock or any other securities issued or issuable with respect to or in exchange for the September Shares; provided, that, a security shall cease to be a Registrable Security with respect to a September Investor upon (A) sale by such September Investor pursuant to a registration statement or Rule 144 under the Securities Act of 1933, or (B) such security becoming eligible for sale by such September Investor without restriction pursuant to Rule 144(b)(1). In the event the Company fails to satisfy its obligations under the September Registration Rights Agreement, the Company would be in breach of such agreement, in which event, the September Investors would be entitled to pursue all rights and remedies at law or equity including an injunction or other equitable relief. The September Registration Rights Agreement does not provide an explicitly stated or defined penalty due upon a breach. Because the potential penalty for any breach of the September Registration Rights Agreement is not explicitly stated or defined, which prohibits the Company from applying the guidance of ASC 825-20-15, Registration Payment Arrangements, the Company was required to present the investment of approximately $8,800,000 in the Company’s common stock as common stock outside of stockholders’ equity in the accompanying consolidated balance sheets under ASC 480-10-S99-3, Classification and Measurement of Redeemable Securities.

Pursuant to the September Registration Rights Agreement, the Company filed a registration statement with the SEC on October 26, 2012, to register the September Shares for resale. This registration statement became effective on November 13, 2012 and remained effective as of June 30, 2014.

As of December 31, 2012, the Company had removed the restriction on 3,000,000 of the 8,000,000 September Shares and reclassified the shares to common stock from common stock classified outside of stockholders’ equity. At June 30, 2014, the restriction was eligible for removal from the remaining 5,000,000 restricted September Shares. Therefore, as of December 31, 2013 and June 30, 2014, a total of $5,500,000 and $0, respectively, of common stock relating to restricted September Shares was classified outside of stockholders’ equity related to this transaction.

Activity in common stock classified outside of stockholders’ equity was as follows:

11. Subsequent Events

On July 30, 2014 (the “Closing Date”), the Company entered into a credit agreement (the “SWK Credit Agreement”) with SWK Funding LLC, as the agent (the “Agent”), and the lenders (including SWK Funding LLC) party thereto from time to time (the “Lenders”). The SWK Credit Agreement provides for a multi-draw term loan to the Company (the “Loan”) for up to a maximum 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 outstanding principal balance under the SWK Credit Agreement will bear interest at a rate per annum equal to the LIBOR Rate (subject to a minimum amount of one percent (1.0%) plus twelve and half percent (12.5%), and will be 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 with November 15, 2014, (ii) upon a prepayment of the Loan and (iii) at maturity in cash. Upon the earlier of (a) the Term Loan Maturity Date or (b) full repayment of the Loan, the Company is required to pay an exit fee.

In addition, on the Closing Date, the Company issued the Agent a warrant (the “Initial Warrant”) to purchase 681,090 shares of the Company's common stock, par value $0.01 per share (the “Common Stock”). The Initial Warrant is exercisable up to and including July 30, 2020 at an exercise price of $0.936 per share, subject to adjustment. The Agent may exercise the Initial Warrant on a cashless basis at any time. In the event the Agent exercises the Initial Warrant on a cashless basis the Company will not receive any proceeds. The exercise price of the Initial Warrant is subject to customary adjustments provisions for stock splits, stock dividends, recapitalizations and the like.

The remaining $3,500,000 of the Loan Commitment Amount (the “Subsequent Term Loan”) may be advanced to the Company upon written request to the Agent during the period beginning on the Closing Date and ending February 28, 2016 provided that (i) no default or event of default has occurred or is continuing under the SWK Credit Agreement, (ii) the aggregate revenue recognized by the Company and any of its subsidiaries during any period of four (4) consecutive fiscal quarters ending prior to December 31, 2015, exceeds a certain dollar amount threshold and (iii) the Agent has received an executed warrant (the “Subsequent Term Loan Warrant”) to purchase a number of shares of Common Stock equal to the number obtained when the amount of the Subsequent Term Loan is multiplied by 7.5% and the product is divided by the exercise price of such warrant. The exercise price of the Subsequent Term Loan Warrant will be equal to 1.2 times the lower of (a) the average closing price of the Common Stock on the previous 20 trading days before the closing date of the Subsequent Term Loan, or (b) the closing price of the Common Stock on the last trading day prior to such Subsequent Term Loan’s closing date. The Subsequent Term Loan Warrant will be exercisable for a period of six years from the closing date of the Subsequent Term Loan, subject to adjustment. Upon issuance, the Agent may exercise the Subsequent Term Loan Warrant on a cashless basis at any time. In the event the Lender exercises the Subsequent Term Loan Warrant on a cashless basis we will not receive any proceeds. The exercise price of the Subsequent Term Loan Warrant is subject to customary adjustments provisions for stock splits, stock dividends, recapitalizations and the like.

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 US$750,000 on any such payment date; and (v) fifth, all remaining amounts to the Company.

The SWK Credit Agreement contains customary affirmative and negative covenants for credit facilities of its type, including limiting 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 revenues requirements.

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 it is not otherwise permitted under the SWK Credit Agreement.

On July 30, 2014, in connection with the SWK Credit Agreement, the Company and Silicon Valley Bank entered into a Waiver and Sixth Amendment to Loan and Security Agreement (“Sixth Amendment”). The Sixth Amendment waived previous defaults under the loan agreement, modified the financial covenants, extended the maturity of the loan to July 25, 2016, modified the interest rate to the prime rate published by the Wall Street Journal plus 2.25% per annum, and implemented a pre-payment fee of $40,000. The financial covenants under the Sixth Amendment include a revenue covenant and a liquidity covenant that conform with and are cross defaulted with the revenue covenant and liquidity covenant of the SWK Credit Agreement. The Company will pay a closing fee of $10,000 for the Sixth Amendment on July 18, 2015, approximately one year from the date of the closing.

At the annual meeting of stockholders of the Company held on July 10, 2014, the Company’s stockholders approved an amendment to the Company’s Certificate of Incorporation, as amended, to increase the number of authorized shares of the Company’s common stock, par value $0.01 per share, from 50 million to 70 million shares. The approved Certificate of Amendment to the Certificate of Incorporation of the Company, as amended, was filed with the Secretary of State of the State of Delaware on July 11, 2014 and was effective upon filing.

The following discussion of our financial condition and results of operations should be read in conjunction with our unaudited condensed consolidated financial statements and related notes to the financial statements included elsewhere in this Quarterly Report on Form 10-Q for the period ended June 30, 2014 and our audited consolidated financial statements for the year ended December 31, 2013 included in our Annual Report on Form 10-K for the year ended December 31, 2013 previously filed with the Securities and Exchange Commission.

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 chemotherapy 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;

• Broadening our offerings with the introduction of the former Pathwork Diagnostics Tissue of Origin^TM test that was acquired when we purchased the Pathwork Diagnostics assets in August 2013 and moved the assets to our Los Angeles facility. We began selling the ResponseDX: Tissue of Origin^TM 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, 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 formalin-fixed paraffin embedded (“FFPE”) patient biopsies for the development of diagnostic tests.

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, and breast cancer patients’ tumor tissue specimens through our ResponseDX: Lung^® , ResponseDX: Colon^® , ResponseDX: Gastric^® , ResponseDX: Melanoma ^® , ResponseDX: Thyroid^TM and ResponseDX: Breast^TM 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.

In August 2013, the Company acquired substantially all of the assets of Pathwork Diagnostics, Inc. including its FDA-cleared Tissue of Origin^TM cancer test. This newly acquired test was launched commercially by the Company in February 2014 as the ResponseDX: Tissue of Origin^TM test. The ResponseDX: Tissue of Origin^TM 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^TM 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 cancers. The test received FDA clearance in June 2010.

As of June 30, 2014, our ResponseDX^® sales team consisted of 18 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 plan to build out our product offering to include a ResponseDX^® Glioma profile as well as 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. 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, investments in 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.

We anticipate that, over the next 12 months, a substantial portion of our capital resources and efforts will be focused on sales and marketing activities related to our ResponseDX^® diagnostic tests, research and development to expand our series of diagnostic tests for cancer patients, and for other general corporate purposes.

Research and development is crucial to the Company’s development as we seek to expand our series of diagnostic tests for cancer patients. Our research and development expenses represented 11.5% and 9.9% of our total operating expenses for the three months ended June 30, 2013 and 2014, respectively, and 9.6% and 9.7% of our total operating expenses for the six months ended June 30, 2013 and 2014, respectively. Major components of the $447,686 and $473,324 in research and development expenses for the three months ended June 30, 2013 and 2014, respectively, and of the $744,886 and $940,890 in research and development expenses for the six months ended June 30, 2013 and 2014, respectively, included supplies and reagents for our research activities, sample procurement costs, personnel costs and patent fees. We expect research and development expenses to increase as we work to develop additional aspects of our technology and to study diagnostic indicators for various forms of cancer.

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, if the minimum assay requirements are not met.

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 expected collections 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, a 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. 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, the Centers for Medicare and Medicaid Services (“CMS”) issued fees for some, but not all, of the CPT codes used by the Company. It is uncertain if continued guidance provided to Medicare and the local MAC by impacted organizations will result in additional fee increases or additional positive coverage determinations in 2014. If, however, the current level of reduction in reimbursement rates is adopted as is, it may have a material adverse effect on the Company's operations.

As a result of these CPT code changes and Medicare price changes, 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 performed analyses that considered our historical patterns of revenue by payor in conjunction with the fluctuations we experienced in the three and six months ended June 30, 2013 and 2014 to arrive at the revenue recorded during those periods. We believe that the changes in CPT codes and pricing that are causing confusion and erratic payment experience in the payor community will take some time to resolve. The time needed for resolution will depend upon Medicare and the local MAC releasing additional pricing changes and potentially, revisions to previously revised prices, and upon the private payor community adopting the new CPT codes and some level of revised pricing. Accordingly, our revenue recognition estimates could be materially affected in future periods as pricing and payments patterns change and develop, and we may be materially affected by future or retroactive price changes.

On July 8, 2013, CMS released a new proposed rulemaking entitled “Medicare Program; Revisions to Payment Policies under the Physician Fee Schedule, Clinical Laboratory Fee Schedule & Other Revisions to Part B for CY 2014”. This proposed rule contains a number of provisions that may adversely impact the level of reimbursement for a variety of tests for which the Company receives reimbursement from the Medicare program beginning in 2014. Among other things, CMS has proposed examining approximately 1,200 laboratory tests that appear on the Clinical Lab Fee Schedule (“CLFS”) over a period of five years to determine whether advances in technology may have reduced the cost of providing such tests and whether or not the level of reimbursement should be revised. The Company is currently performing molecular testing which is reimbursed using CPT codes that fall on the CLFS. CMS has also proposed changing the methodology used to determine reimbursement rates for the technical component of certain tests reimbursed off of the Physician Fee Schedule (“PFS”). Among other provisions, CMS has proposed limiting the Relative Value Units (“RVUs”) ascribed to the Practice Expense component of their reimbursement formula for tests performed in “Non-Facilities” (which would include most clinical laboratories like the Company) to the RVUs that have been ascribed for the same procedures under the Hospital Outpatient Prospective Payment System, or the Ambulatory Payment Classification (“APC”) system which are used to reimburse “Facilities” (such as hospitals and ambulatory surgery centers). The Company currently performs FISH testing, which may be impacted by this PFS rule change if it is enacted.

Additionally, CMS has as part of its regulatory structure the National Correct Coding Initiative (“NCCI”). Recent changes to NCCI guidance may reduce allowable quantities billed for FISH testing. These changes would lower reimbursement amounts for FISH tests, and there can be no assurance that CMS will make any modifications in the existing language of the NCCI documents.

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 revenue 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 $86,908 and $10,449 for the three months ended June 30, 2013 and 2014, respectively, and were $191,014 and $21,410 for the six months ended June 30, 2013 and 2014, respectively. 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 fixed percentage royalty fee for revenue that we generate through use of this technology. Royalties expensed in cost of revenue under this agreement totaled $84,362 and $113,704 for the three months ended June 30, 2013 and 2014, respectively, and were $174,507 and $158,077 for the six months ended June 30, 2013 and 2014, respectively.

We are subject to potentially significant variations in royalties recorded in any period. While the amount paid is based on a fixed percentage from revenues 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.

25

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. To date, our clients have primarily been large pharmaceutical companies. Bad debts to date have been minimal and there is no allowance for doubtful accounts for our pharmaceutical revenue at December 31, 2013 and June 30, 2014.

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.  Based on the historical experience for our Medicare and Private Payor accounts, we have determined, based on a detailed analysis, that accounts receivable associated with certain billings are unlikely to be collected. Therefore, we have recorded an allowance for doubtful accounts of $2,404,659 and $1,912,668 as of December 31, 2013 and June 30, 2014, respectively.

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.

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 June 30, 2014 and June 30, 2013

Revenue:   Revenue was $4,281,235 for the quarter ended June 30, 2014, as compared to $5,313,914 for the quarter ended June 30, 2013, a decrease of $1,032,679 or 19.4%. The decrease was due solely to a decline in pharmaceutical revenue of $1,608,556 or 72.9% offset by an increase in ResponseDX^® revenue of $575,876 or 18.5%. ResponseDX^® revenue accounted for 86.0% of total revenue for the quarter ended June 30, 2014 compared to 58.5% for the quarter ended June 30, 2013. The decrease in pharmaceutical client revenue related to the completion of certain studies in earlier periods by pharmaceutical clients and the realization of a $500,000 milestone payment from GSK in the prior year quarter. 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.

Cost of Revenue:   Cost of revenue for the quarter ended June 30, 2014 was $2,585,738 as compared to $2,707,966 for the quarter ended June 30, 2013, a decrease of $122,228 or 4.5%. Cost of revenue declined less than did revenue due to the fixed and semi-fixed nature of many of the cost items. The decrease in cost of revenue resulted primarily from lower laboratory supplies and reagents and royalties of $273,263 offset by higher depreciation of $52,106, rent of $36,452 and equipment maintenance, service and repair of $55,324. For items that increased, the higher 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. Cost of revenue as a percentage of revenue was 60.4% for the quarter ended June 30, 2014, as compared to 51.0% for the quarter ended June 30, 2013.

26

Sales and Marketing Expenses:   Sales and marketing expenses were $1,283,080 for the quarter ended June 30, 2014, which was consistent with $1,321,760 for the quarter ended June 30, 2013. 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 $3,046,599 for the quarter ended June 30, 2014, as compared to $2,109,268 for the quarter ended June 30, 2013, an increase of $937,331 or 44.4%. This increase resulted primarily from higher bad debt expense of $1,017,855 offset by lower personnel costs of $119,875.

Research and Development Expenses:   Research and development expenses were $473,324 for the quarter ended June 30, 2014, as compared to $447,686 for the quarter ended June 30, 2014, an increase of $25,638 or 5.7%. This increase resulted primarily from efforts to develop new tests and to enhance existing tests. The increase in expense was the result of higher legal fees of $149,046 offset by lower laboratory supplies and reagents costs of $77,969 and lower personnel costs of $54,599. We expect to continue to invest in research and development as we continue to 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 on 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 $23,151 for the three months ended June 30, 2014 compared to $20,756 for the three months ended June 30, 2013. The increase was primarily due to new capital leases for equipment. Other expense increased to $8,260 for the three months ended June 30, 2014 compared to $3,634 for the three months ended June 30, 2013 due to higher realized foreign currency exchange losses.

Net Income/(Loss):   As a result of the foregoing, our net loss increased by $1,841,761 to $3,138,915 for the three months ended June 30, 2014 as compared to a net loss of $1,297,154 for the three months ended June 30, 2013.

Six Months Ended June 30, 2014 and June 30, 2013

Revenue:   Revenue was $8,176,169 for the six months ended June 30, 2014, as compared to $10,938,105 for the six months ended June 30, 2013, a decrease of $2,761,936 or 25.3%. The decline was solely the result of a decrease in pharmaceutical revenue of $3,472,868 or 74.7% offset by an increase in ResponseDX^® revenue of $710,932 or 11.3%. The decrease in pharmaceutical client revenue related to the completion of certain studies by pharmaceutical clients. 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 ResponseDX: Tissue of Origin^TM test.

Cost of Revenue:   Cost of revenue for the six months ended June 30, 2014 was $5,024,114 as compared to $5,241,688 for the six months ended June 30, 2013, a decrease of $217,574 or 4.2%. Cost of revenue declined less than did revenue due to the fixed and semi-fixed nature of many of the cost items and due to the launch of our ResponseDX: Tissue of Origin^TM test in early 2014. The decrease resulted primarily from lower laboratory supplies and reagent costs of $599,369, royalties of $186,033 offset by higher depreciation of $102,694, personnel costs of $148,687, equipment maintenance, repair and service of $99,142, equipment operating leases of $56,979 and rent of $81,522. For items that increased, the higher 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. Cost of revenue as a percentage of revenue was 61.4% for the six months ended June 30, 2014, as compared to 47.9% for the six months ended June 30, 2013.

Sales and Marketing Expenses:   Sales and marketing expenses were $2,735,984 for the six months ended June 30, 2014, which was consistent with expenses of $2,763,995 for the six months ended June 30, 2013. 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 $6,060,556 for the six months ended June 30, 2014, as compared to $4,244,433 for the six months ended June 30, 2013, an increase of $1,816,123 or 42.8%. The increase resulted primarily from higher bad debt expense of $1,843,243.

Research and Development Expenses:   Research and development expenses were $940,890 for the six months ended June 30, 2014, as compared to $744,886 for the six months ended June 30, 2013, an increase of $196,004 or 26.3%. This increase resulted primarily from higher laboratory supplies and reagents costs of $39,255 and higher legal expense of $141,291. We expect continued investment 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 on our revolving credit facility with Silicon Valley Bank and other equipment financing arrangements as well as our realized and unrealized foreign currency exchange gains or losses on our Euro-denominated receivables. Interest expense increased to $47,372 for the six months ended June 30, 2014 compared to $40,186 for the same period in 2013. The increase primarily relates to new capital leases for equipment. Realized and unrealized losses on currency exchange rate fluctuations decreased $13,753 for the six months ended June 30, 2014 to $10,667 compared to $24,420 for the same period in 2013. The decrease primarily relates to a decrease in unrealized foreign currency losses resulting from changes in the US dollar- Euro exchange rates.

Income Taxes:   As of June 30, 2014 and 2013, we have incurred substantial losses and have generated no taxable income. Therefore, a full valuation allowance has been recorded for the deferred tax assets since we do not believe the recoverability of the deferred income tax assets in the near future is more likely than not.

Net Income/(Loss):   As a result of the foregoing, our net loss increased by $4,521,953, or 213.2%, to $6,643,411 for the six months ended June 30, 2014 as compared to a net loss of $2,121,458 for the six months ended June 30, 2013.

Liquidity and Capital Resources

We incurred a net loss of $6,643,411 during the six months ended June 30, 2014. Since our inception in September 1999, we have incurred cumulative losses and as of June 30, 2014, we had an accumulated deficit of $71,940,591. 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. Management intends to effectively manage cash flows in 2014 and 2015 and expects that cash and cash equivalents, as well as other available resources, will be sufficient to meet the Company’s working capital requirements through the next 12 months. Nevertheless, until we can generate and maintain sufficient revenues to finance our cash requirements, which we may never do, we expect to finance additional cash needs primarily through public or private equity offerings, strategic collaborations, our line of credit, our credit facility and other financing opportunities. We do not know whether additional funding will be available on acceptable terms, if at all. If we are not able to secure additional funding when needed, we may have to delay, reduce the scope of or eliminate selling and marketing activities or research and development programs which may have a material adverse effect on the Company.

On July 30, 2014, we entered into a credit agreement (the “SWK Credit Agreement”) with SWK Funding LLC, as the agent (the “Agent”), and the lenders (including SWK Funding LLC) party thereto from time to time (the “Lenders”). The SWK Credit Agreement provides for a multi-draw term loan to the Company (the “Loan”) for up to a maximum 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 July 14, 2011, the Company entered into a line of credit agreement with Silicon Valley Bank (the “Bank”), and on July 30, 2014, subsequent to the end of the quarter, the agreement was amended by the Waiver and Sixth Amendment to Loan and Security Agreement. The line of credit is collateralized by the Company’s pharmaceutical, Private Payor and Medicare receivables. As of June 30, 2014, the amount the Company can draw from the line of credit was $2,000,000 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 credit line. As of June 30, 2014, the interest fees associated with this line of credit were set at the prime rate plus 1%. During the three and six months ended June 30, 2013 and 2014, the rate charged to the Company was 5%. As needed from time to time, the Company may draw on this line for use for general corporate purposes. As of December 31, 2013 and June 30, 2014, the Company had drawn $1,000,000 and $1,500,000, respectively, against the line of credit. The line of credit is subject to various financial covenants. As of June 30, 2014, the Company was in compliance with the covenants. Historically, however, the Company has been out of compliance with the covenants from time to time, and the Company has received waivers and forbearance agreements from the Bank.

As of December 31, 2013, the line of credit under the credit agreement with the Bank was classified as a non-current liability on the accompanying condensed consolidated balance sheets as the line of credit had a maturity date of March 7, 2015, which was greater than one year from the date of the balance sheet. As of June 30, 2014, the line of credit under the credit agreement was classified as a non-current liability because the Waiver and Sixth Amendment to Loan and Security Agreement (further described below) extended the maturity of the facility to July 25, 2016.

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.

On July 30, 2014, in connection with entering into SWK Credit Agreement, the Company and the Bank entered into a Waiver and Sixth Amendment to Loan and Security Agreement (“Sixth Amendment”). The Sixth Amendment waived previous defaults under the loan agreement, modified the financial covenants, extended the maturity of the loan to July 25, 2016, modified the interest rate to the prime rate published by the Wall Street Journal plus 2.25% per annum, and implemented a pre-payment fee of $40,000. The financial covenants under the Sixth Amendment include a revenue covenant and a liquidity covenant that conform with and are cross defaulted with the revenue covenant and liquidity covenant of the SWK Credit Agreement. The Company will pay a closing fee of $10,000 for the Sixth Amendment on July 18, 2015, approximately one year from the date of the closing. 

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.

Sales of Common Stock

Under the Company’s Articles of Incorporation, the Company has one class of common stock and its holders have no preemptive, subscription, redemption or conversion rights. As described below, the Company sold shares of its common stock during 2012 and 2013. In connection with certain of these offerings, the Company entered into registration rights agreements with the purchasers of the common shares which give such purchasers certain registration rights.

February 2012 Private Placement

On February 2, 2012, the Company entered into purchase agreements with various investors (collectively, the “February Investors”) for the private placement of an aggregate of 5,257,267 newly-issued shares of the Company’s common stock (the “February Shares”) at a purchase price of $1.50 per share (the “February 2012 Private Placement”). Net cash proceeds raised in the February 2012 Private Placement were approximately $7,822,000. The February Investors participating in the February 2012 Private Placement were various institutions and all the then current officers and directors of the Company. The final closing of the February 2012 Private Placement (the “February Closing”) occurred on February 2, 2012.

In connection with the February 2012 Private Placement, the Company also entered into registration rights agreements, each dated February 2, 2012, with the February Investors pursuant to which the Company agreed to file, within 90 days of the February Closing, a registration statement with the SEC to register the February Shares for resale, which registration statement was required to become effective within 180 days following the February Closing. The Company also granted the February Investors certain “piggyback” registration rights, which are triggered if the Company proposes to file a registration statement for its own account or the account of one or more shareholders until the earlier of the sale of all of the February Shares or the February Shares becoming eligible for sale under Rule 144(b)(1) without restriction.

Pursuant to the registration rights agreements dated February 2, 2012, the Company filed a registration statement with the SEC on April 30, 2012, to register the February Shares for resale. This registration statement became effective on May 17, 2012 and remained effective as of June 30, 2014.

September 2012 Private Placement

On September 13, 2012, the Company entered into a purchase agreement (the “Purchase Agreement”) with Glaxo Group Limited, an affiliate of GSK (the “GSK Investor”) and two existing investors, Swiftcurrent Partners, L.P. and Swiftcurrent Offshore, Ltd. (collectively with the GSK Investor, the “September Investors”) for the private placement of an aggregate of 8,000,000 newly-issued shares of the Company’s common stock (the “September Shares”) at a purchase price of $1.10 per share (the “September 2012 Private Placement”). The Company raised gross cash proceeds of $8,800,000 in the September 2012 Private Placement, which closed on September 13, 2012 (the “Closing”).

Pursuant to the Purchase Agreement, for so long as the GSK Investor or its affiliates own at least 50% of the September Shares it purchased pursuant to the Purchase Agreement, the GSK Investor has the right to designate one non-voting board observer (the "Board Observer"). The Board Observer, if appointed, has the right to attend all meetings of the Board of Directors of the Company and to receive all board meeting materials, subject to certain restrictions set forth in the Purchase Agreement. As of the date hereof, the GSK Investor has not exercised its right to designate the Board Observer.

In connection with the September 2012 Private Placement, the Company also entered into a registration rights agreement, dated September 13, 2012 (the “September Registration Rights Agreement”), with the September Investors pursuant to which the Company agreed to file, within 45 days of the Closing, a registration statement with the SEC to register the September Shares for resale, which registration statement was required to become effective within 180 days following the Closing. The Company also granted the September Investors certain “piggyback” registration rights, which are triggered if the Company proposes to file a registration statement for its own account or the account of one or more stockholders until the earlier of the sale of all of the September Shares or the September Shares becoming eligible for sale under Rule 144(b)(1) without restriction.

Under the September Registration Rights Agreement, the Company is obligated to use commercially reasonable efforts to cause a registration statement to become effective and to remain continuously effective and to maintain the listing of the covered common stock on NASDAQ or other exchanges, as defined, for a period that will terminate upon the earlier of (i) the date on which all Registrable Securities covered by such Registration Statement as amended from time to time, have been sold, (ii) the date on which there are no longer any Registrable Securities outstanding or (iii) three years from the date of filing of such Registration Statement (the “Effectiveness Period”) and advise each September Investor in writing when the Effectiveness Period has expired. “Registrable Securities” means (i) the September Shares and (ii) shares of capital stock or any other securities issued or issuable with respect to or in exchange for the September Shares; provided, that, a security shall cease to be a Registrable Security with respect to a September Investor upon (A) sale by such September Investor pursuant to a registration statement or Rule 144 under the Securities Act of 1933, or (B) such security becoming eligible for sale by such September Investor without restriction pursuant to Rule 144(b)(1). In the event the Company fails to satisfy its obligations under the September Registration Rights Agreement, the Company would be in breach of such agreement, in which event, the September Investors would be entitled to pursue all rights and remedies at law or equity including an injunction or other equitable relief. The September Registration Rights Agreement does not provide an explicitly stated or defined penalty due upon a breach.  Because the potential penalty for any breach of the September Registration Rights Agreement is not explicitly stated or defined, which prohibits the Company from applying the guidance of ASC 825-20-15, Registration Payment Arrangements, the Company was required to present the investment of approximately $8,800,000 in the Company’s common stock as common stock outside of stockholders’ equity in the accompanying consolidated balance sheet under ASC 480-10-S99-3, Classification and Measurement of Redeemable Securities.

Pursuant to the September Registration Rights Agreement, the Company filed a registration statement with the SEC on October 26, 2012, to register the September Shares for resale. This registration statement became effective on November 13, 2012 and remained effective as of June 30, 2014.

As of December 31, 2012, the Company had removed the restriction on 3,000,000 of the 8,000,000 September Shares and reclassified the shares to common stock from common stock classified outside of stockholders’ equity. At June 30, 2014, the restriction was eligible for removal from the remaining 5,000,000 restricted September Shares. Therefore, as of December 31, 2013 and June 30, 2014, a total of $5,500,000 and $0, respectively, of common stock relating to restricted September Shares was classified outside of stockholders’ equity related to this transaction.

August 2013 Issuance of Registered Shares of Common Stock of the Company as Part of the Pathwork Assets Acquisition Purchase Price

On August 23, 2013, the Company entered into an asset purchase agreement (the “Pathwork Purchase Agreement”) with Pathwork (assignment for the benefit of creditors), LLC (“Seller”), pursuant to which the Company acquired substantially all of the assets of Pathwork Diagnostics, Inc. (“Pathwork”), which had previously assigned all of its assets to Seller for the benefit of its creditors pursuant to a General Assignment, dated as of April 2, 2013. Pursuant to the Pathwork Purchase Agreement, the Company acquired the Pathwork assets for the following consideration: (i) an aggregate of 500,000 newly-issued registered shares of the Company’s common stock valued at $1.96 per share, or $980,000, issued to two senior secured creditors of Pathwork which were designated by Seller in the Pathwork Purchase Agreement and (ii) a cash payment of $200,000 to Seller.

September 2013 Registered Direct Offering

On September 20, 2013, the Company entered into a definitive agreement with certain institutional investors for the sale of 932,805 shares of its common stock in a registered direct offering at a price of $2.05 per share (the "September 2013 Offering"). The September 2013 Offering was completed on September 25, 2013. Gross proceeds of the September 2013 Offering were $1,912,250. Net proceeds, after deducting the placement agent fee and the September 2013 Offering costs, were approximately $1.7 million.

December 2013 Underwritten Public Offering

On December 13, 2013, the Company entered into an underwriting agreement with National Securities Corporation (the "Underwriter"), pursuant to which the Underwriter agreed to purchase 4,464,443 shares of the Company's common stock (the "Shares") at the public offering price of $1.20 per share less an underwriting discount of 5%. The Shares were offered and sold by the Company pursuant to an effective registration statement on Form S-3 (File No. 333-171266) filed by the Company with the Securities and Exchange Commission on December 17, 2010, as amended, as supplemented by the prospectus supplement dated December 13, 2013 relating to the offering and the accompanying prospectus (the "December 2013 Offering"). The December 2013 Offering was completed on December 18, 2013. Gross proceeds of the December 2013 Offering were $5,357,332. Net proceeds, after deducting the placement agent fee and the December 2013 Offering costs, were approximately $4.8 million.

Comparison of Cash Flows for the Six Months Ended June 30, 2013 and 2014

As of June 30, 2013, we had $8,148,599 in cash and cash equivalents, working capital of $9,693,565 and an accumulated deficit of $65,297,179. As of June 30, 2014, we had $2,136,623 in cash and cash equivalents, working capital of $4,199,139 and an accumulated deficit of $71,940,591.

Cash flows provided by operating activities

During the six months ended June 30, 2013, the Company used cash flows in operating activities of $2,832,754 compared to $6,279,368 used in the six months ended June 30, 2014. The increase in cash used in operating activities of $3,446,614 was due mainly to an increase in the net loss from $2,121,458 for the six months ended June 30, 2013 to $6,643,411 for the six months ended June 30, 2014. Other items that impacted cash flows from operating activities include increases in accounts receivable, prepaid expenses, royalties and payroll-related liabilities and decreases in accounts payable and accrued expenses.

The increase in accounts receivable related mainly to increases in Medicare and Private Payor receivables resulting from the recent changes to the molecular codes used for billing. It is anticipated that these billings will continue to take longer to collect in the short-term as a result of these recent changes.

Cash flows used in investing activities

Net cash used in investing activities was $236,803 for the six months ended June 30, 2013 and $135,023 for the six months ended June 30, 2014. The reduction in cash used in investing activities was primarily attributable to lower purchases of equipment and software.

Cash flows used in financing activities

Cash flows from financing activities for the six months ended June 30, 2013 used net cash of $88,104 for repayment of capital lease obligations. Cash flows from financing activities for the six months ended June 30, 2014 provided net cash of $425,616 as a result of drawing on the line of credit and receiving proceeds from stock option exercises net of repayment of capital lease obligations.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

Recent Accounting Pronouncements

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 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. We will adopt ASU 2014-09 on January 1, 2017 and are currently evaluating the impact that this adoption will have on our consolidated financial statements. At this time, we have not determined the transition method that will be used.

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 June 30, 2014 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

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 June 30,				Six Months Ended June 30,
	2013		2014		2013		2014

Basic and diluted loss per share	$	(0.04)	$	(0.08)	$	(0.06)	$	(0.17)

Outstanding stock options to purchase 2,465,390 and 2,210,229 shares of Common Stock of the Company for the periods ended June 30, 2013 and 2014, 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 June 30, 2013 and 2014.

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.

Since its inception, the Company has devoted substantial effort in developing its products and has incurred losses and negative cash flows from operations. At June 30, 2014, the Company had an accumulated deficit of $71,940,591. 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. Management believes that existing cash and cash equivalents, as well as other available resources, will be sufficient to meet the Company’s working capital requirements through the next twelve months. The Company’s ability to successfully carry out its business plan is primarily dependent upon its ability to (1) attract and retain knowledgeable employees, (2) generate significant revenues and (3) if needed, obtain capital at acceptable costs. Until the Company can generate and maintain sufficient revenue to finance its cash requirements, the Company expects to satisfy its future cash needs primarily through public or private equity offerings, strategic collaborations, the line of credit, the credit facility and other financing opportunities. However, there can be no assurance that any additional financing or strategic investments will be available on acceptable terms, if at all. If the Company is not able to secure additional funding when needed, the company have to delay, reduce the scope of or eliminate selling and marketing activities or research and development programs which may have a material adverse effect on the Company.

On July 30, 2014, the Company amended its line of credit agreement, which included extending the maturity to July 25, 2016. Also on July 30, 2014, the Company entered into a credit agreement for a maximum loan commitment of $12,000,000, of which the Company drew $8,500,000 gross proceeds. (See Note 11.)

If events or circumstances occur such that the Company does not meet its operating plan as expected, the Company will most likely be required to reduce certain discretionary spending and/or curtail operations, which could have a material adverse effect on the Company’s ability to achieve its intended business objectives. No adjustments have been made to the accompanying unaudited condensed consolidated financial statements to reflect any of the matters discussed above. The unaudited condensed consolidated financial statements have been prepared on the basis that the Company will continue as a going concern.

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, 2013 were derived from our audited financial statements as of December 31, 2013. The financial statements should be read in conjunction with the Company’s audited December 31, 2013 and 2012 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, 2014.

Accounting Policies [Abstract]

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 2013 or to date in 2014. 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, 2013 and June 30, 2014 were $1,892,384 and $1,060,649, respectively. There were no allowances for doubtful accounts recorded against these pharmaceutical accounts receivable at December 31, 2013 and June 30, 2014.

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 Medicare and Private Payor 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 $2,404,659 and $1,912,668 as of December 31, 2013 and June 30, 2014, respectively. The Company’s bad debt expense for the three months ended June 30, 2013 and 2014 was $349,984 and $1,367,842, respectively, and for the six months ended June 30, 2013 and 2014 was $818,451 and $2,661,693, respectively.

ResponseDX^® accounts receivable as of December 31, 2013 and June 30, 2014, consisted of the following:

	December 31, 2013		June 30, 2014
			(Unaudited)
Net Medicare receivable	$	2,422,611	$	2,574,923
Net Private Payor receivable		4,315,587		4,806,646
		6,738,198		7,381,569
Allowance for doubtful accounts		(2,404,659)		(1,912,668)
Total	$	4,333,539	$	5,468,901

Property and Equipment

Property and equipment are carried at cost less accumulated depreciation and amortization. Depreciation and amortization are calculated using the double declining balance and 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
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.

Intangible Assets

Intangible assets are carried at the cost to obtain them. Purchased software and internally-developed intangible assets are amortized using the straight-line method over estimated useful lives of three to five years. 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.

The Company recorded revenue from pharmaceutical clients for the three months ended June 30, 2013 and 2014 of $2,207,837 and $599,282, respectively and for the six months ended June 30, 2013 and 2014 of $4,649,531 and $1,176,663, respectively.

ResponseDX^® Revenue

Revenues that are derived from ResponseDX^® testing services are recognized in accordance with ASC 605, Revenue Recognition, which requires that four basic criteria 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. We record revenues when our tests have confirmed results, which are evidence that the services have been performed.

Revenues are recorded on an accrual basis as the contractual obligations are completed and as a set of assays is processed through our laboratory under a specified contractual protocol.

ResponseDX^® Private Payor and Medicare revenues 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. 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”).

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

	Three Months				Six Months
	Ended June 30,				Ended June 30,
	(Unaudited)				(Unaudited)
	2013		2014		2013		2014
Net Medicare revenue	$	1,078,473	$	1,211,995	$	2,422,688	$	2,520,416
Net Private Payor revenue		2,027,604		2,469,958		3,865,886		4,479,090
Net ResponseDX® revenue	$	3,106,077	$	3,681,953	$	6,288,574	$	6,999,506

Cost-Containment Measures

Both government and private pay sources have instituted cost-containment measures designed to limit payments made to providers of health care services, which include diagnostic test providers such as the Company, and there can be no assurance that future measures designed to limit payments made to providers will not adversely affect the Company.

Regulatory Matters

A portion of the Company’s revenues are derived from Medicare reimbursement. Laws and regulations governing Medicare programs are complex and subject to change and to interpretation, and the Company may be adversely affected by future changes in the applicable laws and regulations and governmental investigations, lawsuits or private actions which include mandatory damages, fines, penalties, criminal charges, loss or suspension of licenses and/or suspension or exclusion from Medicare and certain other governmental programs. The Company believes that it is in compliance with all applicable laws and regulations and is not aware of any pending or threatened investigations involving allegations of potential wrongdoing.

Medicare reimbursement rates are also subject to regulatory changes and government funding restrictions. In January 2013, a 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. 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. On October 1, 2013, the Centers for Medicare and Medicaid Services (“CMS”) issued fees for some, but not all, of the CPT codes used by the Company. It is uncertain if continued guidance provided to Medicare and the local MAC by impacted organizations will result in additional fee increases or additional positive coverage determinations in 2014. If, however, the current reduction in reimbursement rates is adopted as is, it may have a material adverse effect on the Company's operations.

As a result of these Current Procedural Terminology (“CPT”) code changes and Medicare price changes, 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 performed an analysis that considered our historical patterns of revenue by payor in conjunction with the fluctuations we experienced in the three and six months ended June 30, 2013 and 2014 to arrive at the revenue recorded during those periods. We believe that the changes in CPT codes and pricing that are causing confusion and erratic payment experience in the payor community will take some time to resolve. The time needed for resolution will depend upon Medicare and the local MAC releasing additional pricing changes and potentially, revisions to previously revised prices, and upon the private payor community adopting the new CPT codes and some level of revised pricing. Accordingly, our revenue recognition estimates could be materially affected in future periods as pricing and payments patterns change and develop, and we may be materially affected by future or retroactive price changes.

On July 8, 2013, CMS released a new proposed rulemaking entitled “Medicare Program; Revisions to Payment Policies under the Physician Fee Schedule, Clinical Laboratory Fee Schedule & Other Revisions to Part B for CY 2014”. This proposed rule contains a number of provisions that may adversely impact the level of reimbursement for a variety of tests for which the Company receives reimbursement from the Medicare program beginning in 2014. Among other things, CMS has proposed examining approximately 1,200 laboratory tests that appear on the Clinical Lab Fee Schedule (“CLFS”) over a period of five years to determine whether advances in technology may have reduced the cost of providing such tests and whether or not the level of reimbursement should be revised. The Company is currently performing molecular testing which is reimbursed using CPT codes that fall on the CLFS. CMS has also proposed changing the methodology used to determine reimbursement rates for the technical component of certain tests reimbursed off of the Physician Fee Schedule (“PFS”). Among other provisions, CMS has proposed limiting the Relative Value Units (“RVUs”) ascribed to the Practice Expense component of their reimbursement formula for tests performed in “Non-Facilities” (which would include most clinical laboratories like the Company) to the RVUs that have been ascribed for the same procedures under the Hospital Outpatient Prospective Payment System, or the Ambulatory Payment Classification (“APC”) system which are used to reimburse “Facilities” (such as hospitals and ambulatory surgery centers). The Company currently performs FISH testing, which may be impacted by this PFS rule change if it is enacted.

Additionally, CMS has as part of its regulatory structure the National Correct Coding Initiative (“NCCI”). Recent changes to NCCI guidance may reduce allowable quantities billed for FISH testing. These changes would lower reimbursement amounts for FISH tests, and there can be no assurance that CMS will make any modifications in the existing language of the NCCI documents.

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.

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”), 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 licenses 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 the technology. These royalties are calculated as a fixed percentage of revenue that we generate from use of the technology licensed from USC. We also maintain a non-exclusive license to use Roche Molecular Systems, Inc.’s (“Roche”) PCR, homogenous PCR, and reverse transcription PCR processes. We pay Roche a fixed percentage royalty fee for revenue that we generate through use of this technology.

The Company is subject to potentially significant variations in royalties recorded in any period. While the amount paid is based on a fixed percentage from revenues 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. However, the licensors have not reviewed the Company’s updated royalty calculations. As a result, the Company has not reduced the historical accrued liability for royalties but has adjusted the current period accrual based on the revised calculation.

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 warranties 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”) and, on July 30, 2014, subsequent to the end of the quarter, the agreement was amended by the Waiver and Sixth Amendment to Loan and Security Agreement. The line of credit is collateralized by the Company’s pharmaceutical, Private Payor and Medicare receivables. As of June 30, 2014, the amount the Company can draw from the line of credit was $2,000,000 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 credit line. As of June 30, 2014, the interest fees associated with this line of credit were set at the prime rate plus 1%. The fee for the unused portion of the facility was 0.25%. During the three and six months ended June 30, 2013 and 2014, the rate charged to the Company was 5%. As needed from time to time, the Company may draw on this line for use for general corporate purposes. As of December 31, 2013 and June 30, 2014, the Company had drawn $1,000,000 and $1,500,000, respectively, against the line of credit. The line of credit is subject to various financial covenants. At June 30, 2014, the Company was in compliance with the covenants. Historically, however, the Company has been out of compliance with the covenants from time to time, and the Company has received waivers and forbearance agreements from the Bank.

As of December 31, 2013, the line of credit under the credit agreement was classified as a non-current liability on the accompanying condensed consolidated balance sheets as the line of credit had a maturity date of March 7, 2015, which was greater than one year from the date of the balance sheet. As of June 30, 2014, the line of credit under the credit agreement was classified as a non-current liability because the Waiver and Sixth Amendment to Loan and Security Agreement extended the maturity of the facility to July 25, 2016.

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.

On July 30, 2014, in connection with entering into a credit agreement with SWK Funding LLC (both as agent and initial lender), the Company and Silicon Valley Bank entered into a Waiver and Sixth Amendment to Loan and Security Agreement (“Sixth Amendment”). The Sixth Amendment waived previous defaults under the loan agreement, modified the financial covenants, extended the maturity of the loan to July 25, 2016, modified the interest rate to the prime rate published by the Wall Street Journal plus 2.25% per annum, and implemented a pre-payment fee of $40,000. The financial covenants under the Sixth Amendment include a revenue covenant and a liquidity covenant that conform with and are cross defaulted with the revenue covenant and liquidity covenant of the SWK Credit Agreement. The Company will pay a closing fee of $10,000 for the Sixth Amendment on July 18, 2015, approximately one year from the date of the closing. For more information, see Note 11 Subsequent Events.

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, 2013 and June 30, 2014, 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 June 30, 2013 and 2014, nominal amounts of interest and penalties were 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.

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’ equity.

Comprehensive Loss

The components of comprehensive loss are accumulated net loss and unrealized foreign currency translation adjustments for the three and six months ended June 30, 2013 and 2014.

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 June 30, 2013 and 2014 were $3,324 and $19,839, respectively, and for the six months ended June 30, 2013 and 2014 were $3,324 and $26,260, 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 June 30, 2014, the Company had $2,124,809 in cash and cash equivalents that exceeded federally insured limits. At June 30, 2014, $12,719 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 two suppliers. The Company made approximately 93% of its reagent purchases from four suppliers during the three months ended June 30, 2013 and made approximately 71% of its reagent purchases from two suppliers during the three months ended June 30, 2014. The Company made approximately 92% of its reagent purchases from four suppliers during the six months ended June 30, 2013 and made approximately 72% of its reagent purchases from two suppliers during the six months ended June 30, 2014.

Recent Accounting Pronouncements

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 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. We will adopt ASU 2014-09 on January 1, 2017 and are currently evaluating the impact that this adoption will have on our consolidated financial statements. At this time, the company has not determined the transition method that will be used.

Summary of Significant Accounting Policies (Policies)

6 Months Ended

Jun. 30, 2014

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 2013 or to date in 2014. 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, 2013 and June 30, 2014 were $1,892,384 and $1,060,649, respectively. There were no allowances for doubtful accounts recorded against these pharmaceutical accounts receivable at December 31, 2013 and June 30, 2014.

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 Medicare and Private Payor 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 $2,404,659 and $1,912,668 as of December 31, 2013 and June 30, 2014, respectively. The Company’s bad debt expense for the three months ended June 30, 2013 and 2014 was $349,984 and $1,367,842, respectively, and for the six months ended June 30, 2013 and 2014 was $818,451 and $2,661,693, respectively.

ResponseDX^® accounts receivable as of December 31, 2013 and June 30, 2014, consisted of the following:

	December 31, 2013		June 30, 2014
			(Unaudited)
Net Medicare receivable	$	2,422,611	$	2,574,923
Net Private Payor receivable		4,315,587		4,806,646
		6,738,198		7,381,569
Allowance for doubtful accounts		(2,404,659)		(1,912,668)
Total	$	4,333,539	$	5,468,901

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 double declining balance and 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
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.

Intangible Assets

Intangible Assets

Intangible assets are carried at the cost to obtain them. Purchased software and internally-developed intangible assets are amortized using the straight-line method over estimated useful lives of three to five years. 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.

The Company recorded revenue from pharmaceutical clients for the three months ended June 30, 2013 and 2014 of $2,207,837 and $599,282, respectively and for the six months ended June 30, 2013 and 2014 of $4,649,531 and $1,176,663, respectively.

ResponseDX^® Revenue

Revenues that are derived from ResponseDX^® testing services are recognized in accordance with ASC 605, Revenue Recognition, which requires that four basic criteria 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. We record revenues when our tests have confirmed results, which are evidence that the services have been performed.

Revenues are recorded on an accrual basis as the contractual obligations are completed and as a set of assays is processed through our laboratory under a specified contractual protocol.

ResponseDX^® Private Payor and Medicare revenues 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. 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”).

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

	Three Months				Six Months
	Ended June 30,				Ended June 30,
	(Unaudited)				(Unaudited)
	2013		2014		2013		2014
Net Medicare revenue	$	1,078,473	$	1,211,995	$	2,422,688	$	2,520,416
Net Private Payor revenue		2,027,604		2,469,958		3,865,886		4,479,090
Net ResponseDX® revenue	$	3,106,077	$	3,681,953	$	6,288,574	$	6,999,506

Cost-Containment Measures

Both government and private pay sources have instituted cost-containment measures designed to limit payments made to providers of health care services, which include diagnostic test providers such as the Company, and there can be no assurance that future measures designed to limit payments made to providers will not adversely affect the Company.

Regulatory Matters

A portion of the Company’s revenues are derived from Medicare reimbursement. Laws and regulations governing Medicare programs are complex and subject to change and to interpretation, and the Company may be adversely affected by future changes in the applicable laws and regulations and governmental investigations, lawsuits or private actions which include mandatory damages, fines, penalties, criminal charges, loss or suspension of licenses and/or suspension or exclusion from Medicare and certain other governmental programs. The Company believes that it is in compliance with all applicable laws and regulations and is not aware of any pending or threatened investigations involving allegations of potential wrongdoing.

Medicare reimbursement rates are also subject to regulatory changes and government funding restrictions. In January 2013, a 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. 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. On October 1, 2013, the Centers for Medicare and Medicaid Services (“CMS”) issued fees for some, but not all, of the CPT codes used by the Company. It is uncertain if continued guidance provided to Medicare and the local MAC by impacted organizations will result in additional fee increases or additional positive coverage determinations in 2014. If, however, the current reduction in reimbursement rates is adopted as is, it may have a material adverse effect on the Company's operations.

As a result of these Current Procedural Terminology (“CPT”) code changes and Medicare price changes, 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 performed an analysis that considered our historical patterns of revenue by payor in conjunction with the fluctuations we experienced in the three and six months ended June 30, 2013 and 2014 to arrive at the revenue recorded during those periods. We believe that the changes in CPT codes and pricing that are causing confusion and erratic payment experience in the payor community will take some time to resolve. The time needed for resolution will depend upon Medicare and the local MAC releasing additional pricing changes and potentially, revisions to previously revised prices, and upon the private payor community adopting the new CPT codes and some level of revised pricing. Accordingly, our revenue recognition estimates could be materially affected in future periods as pricing and payments patterns change and develop, and we may be materially affected by future or retroactive price changes.

On July 8, 2013, CMS released a new proposed rulemaking entitled “Medicare Program; Revisions to Payment Policies under the Physician Fee Schedule, Clinical Laboratory Fee Schedule & Other Revisions to Part B for CY 2014”. This proposed rule contains a number of provisions that may adversely impact the level of reimbursement for a variety of tests for which the Company receives reimbursement from the Medicare program beginning in 2014. Among other things, CMS has proposed examining approximately 1,200 laboratory tests that appear on the Clinical Lab Fee Schedule (“CLFS”) over a period of five years to determine whether advances in technology may have reduced the cost of providing such tests and whether or not the level of reimbursement should be revised. The Company is currently performing molecular testing which is reimbursed using CPT codes that fall on the CLFS. CMS has also proposed changing the methodology used to determine reimbursement rates for the technical component of certain tests reimbursed off of the Physician Fee Schedule (“PFS”). Among other provisions, CMS has proposed limiting the Relative Value Units (“RVUs”) ascribed to the Practice Expense component of their reimbursement formula for tests performed in “Non-Facilities” (which would include most clinical laboratories like the Company) to the RVUs that have been ascribed for the same procedures under the Hospital Outpatient Prospective Payment System, or the Ambulatory Payment Classification (“APC”) system which are used to reimburse “Facilities” (such as hospitals and ambulatory surgery centers). The Company currently performs FISH testing, which may be impacted by this PFS rule change if it is enacted.

Additionally, CMS has as part of its regulatory structure the National Correct Coding Initiative (“NCCI”). Recent changes to NCCI guidance may reduce allowable quantities billed for FISH testing. These changes would lower reimbursement amounts for FISH tests, and there can be no assurance that CMS will make any modifications in the existing language of the NCCI documents.

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.

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”), 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.

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 warranties 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”) and, on July 30, 2014, subsequent to the end of the quarter, the agreement was amended by the Waiver and Sixth Amendment to Loan and Security Agreement. The line of credit is collateralized by the Company’s pharmaceutical, Private Payor and Medicare receivables. As of June 30, 2014, the amount the Company can draw from the line of credit was $2,000,000 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 credit line. As of June 30, 2014, the interest fees associated with this line of credit were set at the prime rate plus 1%. The fee for the unused portion of the facility was 0.25%. During the three and six months ended June 30, 2013 and 2014, the rate charged to the Company was 5%. As needed from time to time, the Company may draw on this line for use for general corporate purposes. As of December 31, 2013 and June 30, 2014, the Company had drawn $1,000,000 and $1,500,000, respectively, against the line of credit. The line of credit is subject to various financial covenants. At June 30, 2014, the Company was in compliance with the covenants. Historically, however, the Company has been out of compliance with the covenants from time to time, and the Company has received waivers and forbearance agreements from the Bank.

As of December 31, 2013, the line of credit under the credit agreement was classified as a non-current liability on the accompanying condensed consolidated balance sheets as the line of credit had a maturity date of March 7, 2015, which was greater than one year from the date of the balance sheet. As of June 30, 2014, the line of credit under the credit agreement was classified as a non-current liability because the Waiver and Sixth Amendment to Loan and Security Agreement extended the maturity of the facility to July 25, 2016.

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.

On July 30, 2014, in connection with entering into a credit agreement with SWK Funding LLC (both as agent and initial lender), the Company and Silicon Valley Bank entered into a Waiver and Sixth Amendment to Loan and Security Agreement (“Sixth Amendment”). The Sixth Amendment waived previous defaults under the loan agreement, modified the financial covenants, extended the maturity of the loan to July 25, 2016, modified the interest rate to the prime rate published by the Wall Street Journal plus 2.25% per annum, and implemented a pre-payment fee of $40,000. The financial covenants under the Sixth Amendment include a revenue covenant and a liquidity covenant that conform with and are cross defaulted with the revenue covenant and liquidity covenant of the SWK Credit Agreement. The Company will pay a closing fee of $10,000 for the Sixth Amendment on July 18, 2015, approximately one year from the date of the closing. For more information, see Note 11 Subsequent Events.

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, 2013 and June 30, 2014, 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 June 30, 2013 and 2014, nominal amounts of interest and penalties were 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.

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’ equity.

Comprehensive Loss

Comprehensive Loss

The components of comprehensive loss are accumulated net loss and unrealized foreign currency translation adjustments for the three and six months ended June 30, 2013 and 2014.

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 June 30, 2013 and 2014 were $3,324 and $19,839, respectively, and for the six months ended June 30, 2013 and 2014 were $3,324 and $26,260, 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 June 30, 2014, the Company had $2,124,809 in cash and cash equivalents that exceeded federally insured limits. At June 30, 2014, $12,719 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 two suppliers. The Company made approximately 93% of its reagent purchases from four suppliers during the three months ended June 30, 2013 and made approximately 71% of its reagent purchases from two suppliers during the three months ended June 30, 2014. The Company made approximately 92% of its reagent purchases from four suppliers during the six months ended June 30, 2013 and made approximately 72% of its reagent purchases from two suppliers during the six months ended June 30, 2014.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

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 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. We will adopt ASU 2014-09 on January 1, 2017 and are currently evaluating the impact that this adoption will have on our consolidated financial statements. At this time, the company has not determined the transition method that will be used.

Royalty Agreements [Member]

Significant Accounting Policies [Line Items]

Revenue Recognition, Services, Licensing Fees [Policy Text Block]

License Fees

The Company licenses 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 the technology. These royalties are calculated as a fixed percentage of revenue that we generate from use of the technology licensed from USC. We also maintain a non-exclusive license to use Roche Molecular Systems, Inc.’s (“Roche”) PCR, homogenous PCR, and reverse transcription PCR processes. We pay Roche a fixed percentage royalty fee for revenue that we generate through use of this technology.

The Company is subject to potentially significant variations in royalties recorded in any period. While the amount paid is based on a fixed percentage from revenues 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. However, the licensors have not reviewed the Company’s updated royalty calculations. As a result, the Company has not reduced the historical accrued liability for royalties but has adjusted the current period accrual based on the revised calculation.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Stock Option Plans

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 2014, resulting in the total number of shares that may be issued as of January 1, 2014 to be 3,770,000. As of June 30, 2014, there were 1,463,748 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 2 to 3 year period. The Company had 2,210,229 options outstanding at a weighted average exercise price of $1.85 at June 30, 2014. There were 1,135,063 non-vested stock options outstanding with a weighted average grant date fair value of $1.34 at June 30, 2014.  As of June 30, 2014, there was $844,038 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 and six months ended June 30, 2013 and 2014 using the Black-Scholes model with the following weighted average assumptions:

	Three Months Ended June 30,						Six Months Ended June 30,

	(Unaudited)			(Unaudited)			(Unaudited)			(Unaudited)

Forfeiture rate		7.0	%		—	%		7.0	%		—	%

** 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 Company’s lack of history of option exercises.

The following table summarizes the stock option activity for the 2006 Plan for the six months ended June 30, 2014:

10. Sale of Common Stock

September 2012 Private Placement

On September 13, 2012, the Company entered into a purchase agreement (the “Purchase Agreement”) with Glaxo Group Limited, an affiliate of GSK (the “GSK Investor”) and two existing investors, Swiftcurrent Partners, L.P. and Swiftcurrent Offshore, Ltd. (collectively with the GSK Investor, the “September Investors”) for the private placement of an aggregate of 8,000,000 newly-issued shares of the Company’s common stock (the “September Shares”) at a purchase price of $1.10 per share (the “September 2012 Private Placement”). The Company raised gross cash proceeds of $8,800,000 in the September 2012 Private Placement, which closed on September 13, 2012 (the “Closing”).

Pursuant to the Purchase Agreement, for so long as the GSK Investor or its affiliates own at least 50% of the September Shares it purchased pursuant to the Purchase Agreement, the GSK Investor has the right to designate one non-voting board observer (the "Board Observer"). The Board Observer, if appointed, has the right to attend all meetings of the Board of Directors of the Company and to receive all board meeting materials, subject to certain restrictions set forth in the Purchase Agreement. As of the date hereof, the GSK Investor has not exercised its right to designate the Board Observer.

In connection with the September 2012 Private Placement, the Company also entered into a registration rights agreement, dated September 13, 2012 (the “September Registration Rights Agreement”), with the September Investors pursuant to which the Company agreed to file, within 45 days of the Closing, a registration statement with the SEC to register the September Shares for resale, which registration statement was required to become effective within 180 days following the Closing. The Company also granted the September Investors certain “piggyback” registration rights, which are triggered if the Company proposes to file a registration statement for its own account or the account of one or more stockholders until the earlier of the sale of all of the September Shares or the September Shares becoming eligible for sale under Rule 144(b)(1) without restriction.

Under the September Registration Rights Agreement, the Company is obligated to use commercially reasonable efforts to cause a registration statement to become effective and to remain continuously effective and to maintain the listing of the covered common stock on NASDAQ or other exchanges, as defined, for a period that will terminate upon the earlier of (i) the date on which all Registrable Securities covered by such Registration Statement as amended from time to time, have been sold, (ii) the date on which there are no longer any Registrable Securities outstanding or (iii) three years from the date of filing of such Registration Statement (the “Effectiveness Period”) and advise each September Investor in writing when the Effectiveness Period has expired. “Registrable Securities” means (i) the September Shares and (ii) shares of capital stock or any other securities issued or issuable with respect to or in exchange for the September Shares; provided, that, a security shall cease to be a Registrable Security with respect to a September Investor upon (A) sale by such September Investor pursuant to a registration statement or Rule 144 under the Securities Act of 1933, or (B) such security becoming eligible for sale by such September Investor without restriction pursuant to Rule 144(b)(1).   In the event the Company fails to satisfy its obligations under the September Registration Rights Agreement, the Company would be in breach of such agreement, in which event, the September Investors would be entitled to pursue all rights and remedies at law or equity including an injunction or other equitable relief. The September Registration Rights Agreement does not provide an explicitly stated or defined penalty due upon a breach.  Because the potential penalty for any breach of the September Registration Rights Agreement is not explicitly stated or defined, which prohibits the Company from applying the guidance of ASC 825-20-15, Registration Payment Arrangements, the Company was required to present the investment of approximately $8,800,000 in the Company’s common stock as common stock outside of stockholders’ equity in the accompanying consolidated balance sheets under ASC 480-10-S99-3, Classification and Measurement of Redeemable Securities.

Pursuant to the September Registration Rights Agreement, the Company filed a registration statement with the SEC on October 26, 2012, to register the September Shares for resale. This registration statement became effective on November 13, 2012 and remained effective as of June 30, 2014.

As of December 31, 2012, the Company had removed the restriction on 3,000,000 of the 8,000,000 September Shares and reclassified the shares to common stock from common stock classified outside of stockholders’ equity. At June 30, 2014, the restriction was eligible for removal from the remaining 5,000,000 restricted September Shares. Therefore, as of December 31, 2013 and June 30, 2014, a total of $5,500,000 and $0, respectively, of common stock relating to  restricted September Shares was classified outside of stockholders’ equity related to this transaction.

Activity in common stock classified outside of stockholders’ equity was as follows:

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 2003 through 2013.

11. Subsequent Events

On July 30, 2014 (the “Closing Date”), the Company entered into a credit agreement (the “SWK Credit Agreement”) with SWK Funding LLC, as the agent (the “Agent”), and the lenders (including SWK Funding LLC) party thereto from time to time (the “Lenders”). The SWK Credit Agreement provides for a multi-draw term loan to the Company (the “Loan”) for up to a maximum 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 outstanding principal balance under the SWK Credit Agreement will bear interest at a rate per annum equal to the LIBOR Rate (subject to a minimum amount of one percent (1.0%) plus twelve and half percent (12.5%), and will be 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 with November 15, 2014, (ii) upon a prepayment of the Loan and (iii) at maturity in cash. Upon the earlier of (a) the Term Loan Maturity Date or (b) full repayment of the Loan, the Company is required to pay an exit fee.

In addition, on the Closing Date, the Company issued the Agent a warrant (the “Initial Warrant”) to purchase 681,090 shares of the Company's common stock, par value $0.01 per share (the “Common Stock”). The Initial Warrant is exercisable up to and including July 30, 2020 at an exercise price of $0.936 per share, subject to adjustment. The Agent may exercise the Initial Warrant on a cashless basis at any time. In the event the Agent exercises the Initial Warrant on a cashless basis the Company will not receive any proceeds. The exercise price of the Initial Warrant is subject to customary adjustments provisions for stock splits, stock dividends, recapitalizations and the like.

The remaining $3,500,000 of the Loan Commitment Amount (the “Subsequent Term Loan”) may be advanced to the Company upon written request to the Agent during the period beginning on the Closing Date and ending February 28, 2016 provided that (i) no default or event of default has occurred or is continuing under the SWK Credit Agreement, (ii) the aggregate revenue recognized by the Company and any of its subsidiaries during any period of four (4) consecutive fiscal quarters ending prior to December 31, 2015, exceeds a certain dollar amount threshold and (iii) the Agent has received an executed warrant (the “Subsequent Term Loan Warrant”) to purchase a number of shares of Common Stock equal to the number obtained when the amount of the Subsequent Term Loan is multiplied by 7.5% and the product is divided by the exercise price of such warrant. The exercise price of the Subsequent Term Loan Warrant will be equal to 1.2 times the lower of (a) the average closing price of the Common Stock on the previous 20 trading days before the closing date of the Subsequent Term Loan, or (b) the closing price of the Common Stock on the last trading day prior to such Subsequent Term Loan’s closing date. The Subsequent Term Loan Warrant will be exercisable for a period of six years from the closing date of the Subsequent Term Loan, subject to adjustment. Upon issuance, the Agent may exercise the Subsequent Term Loan Warrant on a cashless basis at any time. In the event the Lender exercises the Subsequent Term Loan Warrant on a cashless basis we will not receive any proceeds. The exercise price of the Subsequent Term Loan Warrant is subject to customary adjustments provisions for stock splits, stock dividends, recapitalizations and the like.

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 US$750,000 on any such payment date; and (v) fifth, all remaining amounts to the Company.

The SWK Credit Agreement contains customary affirmative and negative covenants for credit facilities of its type, including limiting 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 revenues requirements.

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 it is not otherwise permitted under the SWK Credit Agreement.

On July 30, 2014, in connection with the SWK Credit Agreement, the Company and Silicon Valley Bank entered into a Waiver and Sixth Amendment to Loan and Security Agreement (“Sixth Amendment”). The Sixth Amendment waived previous defaults under the loan agreement, modified the financial covenants, extended the maturity of the loan to July 25, 2016, modified the interest rate to the prime rate published by the Wall Street Journal plus 2.25% per annum, and implemented a pre-payment fee of $40,000. The financial covenants under the Sixth Amendment include a revenue covenant and a liquidity covenant that conform with and are cross defaulted with the revenue covenant and liquidity covenant of the SWK Credit Agreement. The Company will pay a closing fee of $10,000 for the Sixth Amendment on July 18, 2015, approximately one year from the date of the closing.

At the annual meeting of stockholders of the Company held on July 10, 2014, the Company’s stockholders approved an amendment to the Company’s Certificate of Incorporation, as amended, to increase the number of authorized shares of the Company’s common stock, par value $0.01 per share, from 50 million to 70 million shares. The approved Certificate of Amendment to the Certificate of Incorporation of the Company, as amended, was filed with the Secretary of State of the State of Delaware on July 11, 2014 and was effective upon filing.

Operating Leases

The Company leases 27,446 square feet of office and laboratory space in Los Angeles, California, under a non-cancelable operating lease that was amended and extended on February 3, 2014 and will expire on June 30, 2015. The Company has the option to extend the lease to June 30, 2016. The Company also leased 1,460 square feet of space in Frederick, Maryland, where administrative functions were performed until July 31, 2012. The Company moved the administrative functions performed out of this office primarily to its Los Angeles facilities and closed the Maryland office on July 31, 2012. The lease for the Maryland office expired on January 31, 2013.

Rent expense, which is classified in cost of revenue, general and administrative, and research and development expenses was $163,578 and $214,181 for the three months ended June 30, 2013 and 2014, respectively, and was $324,368 and $426,362 for the six months ended June 30, 2013 and 2014, respectively.

Future minimum lease payments by year and in the aggregate, under the Company’s non-cancelable operating leases for facilities, equipment and software as a service, consist of the following at June 30, 2014:

Years Ending December 31,	Unaudited

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, 2013 and June 30, 2014.

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. 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.
