NOTES TO CONDENSED FINANCIAL STATEMENTS

JUNE 30, 2015

(UNAUDITED)

Note 1—Basis of Presentation

Interleukin Genetics, Inc. (“the Company”) develops genetic tests for sale into the emerging personalized health market and performs testing services that can help individuals improve and maintain their health through preventive or therapeutic measures. The Company’s principal operations and markets are located in the United States.

The accompanying condensed financial statements include the accounts of the Company as of June 30, 2015 and December 31, 2014 and for the three and six months ended June 30, 2015 and 2014.

The financial statements have been prepared by the Company in accordance with accounting principles generally accepted in the United States of America for interim financial reporting. Accordingly, they do not include all of the information and notes required by generally accepted accounting principles for complete financial statements. These unaudited condensed financial statements, which, in the opinion of management, reflect all adjustments (including normal recurring adjustments) necessary for a fair presentation, should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. Operating results are not necessarily indicative of the results that may be expected for any future interim period or for the entire 2015 fiscal year.

For information regarding our critical accounting policies and estimates, please refer to “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Estimates” contained in our Annual Report on Form 10-K for the year ended December 31, 2014 and Note 3 to our condensed financial statements contained herein.

Note 2—Operating Matters and Liquidity

The Company has experienced net operating losses since its inception through June 30, 2015. The Company had net losses of $6.3 million and $7.1 million for the years ended December 31, 2014 and 2013, respectively, and $4.0 million for the six months ended June 30, 2015, contributing to an accumulated deficit of $125.1 million as of June 30, 2015.

The Company continues to take steps to reduce genetic test processing costs. Cost savings are primarily achieved through test process improvements. Management believes that the current laboratory space is adequate to process high volumes of genetic tests.

On May 17, 2013, the Company entered into a Common Stock Purchase Agreement (the “2013 Purchase Agreement”) with various accredited investors (the “2013 Investors”), pursuant to which the Company sold securities to the 2013 Investors in a private placement transaction (the “May 2013 Private Placement”). In the May 2013 Private Placement, the Company sold an aggregate of 43,715,847 shares of common stock at a price of $0.2745 per share for gross proceeds of $12,000,000. The 2013 Investors also received warrants to purchase up to an aggregate of 32,786,885 shares of common stock an exercise price of $0.2745 per share (the “2013 Warrants”). The 2013 Warrants are all currently exercisable and have a term of seven years from the date they became exercisable.

On December 23, 2014, the Company entered into a Securities Purchase Agreement (the “2014 Purchase Agreement”) with various accredited investors (the “2014 Investors”), pursuant to which the Company sold to the 2014 Investors in a private placement transaction (the “December 2014 Private Placement”) an aggregate of 50,099,700 shares of common stock at a price of $0.1003 per share for gross proceeds of approximately $5.025 million. The 2014 Investors also received warrants to purchase up to an aggregate of 50,099,700 shares of common stock an exercise price of $0.1003 per share (the “2014 Warrants”). The 2014 Warrants are all currently exercisable and have a term of seven years.

On December 23, 2014, the Company entered into a Venture Loan and Security Agreement (the “Loan Agreement”) with Horizon Technology Finance Corporation (the “Lender”) under which the Company has borrowed $5.0 million. The loan bears interest at a floating rate equal to the One Month LIBOR Rate (with a floor of 0.50%) plus 8.50%. In the event that the One Month LIBOR Rate, as reported in the Wall Street Journal, exceeds 0.50%, the interest rate will be adjusted by an amount equal to the difference between such rates at the end of that particular month. At June 30, 2015, the rate was 9.0% per annum. The loan is to be repaid in forty-five (45) monthly payments consisting of fifteen (15) monthly payments of only interest followed by thirty (30) equal monthly payments of principal and interest. In addition, at the end of the repayment term (or at early termination of the loan) a final payment equal to 4.5% of the loan will be due and payable. The Company’s obligations under the Loan Agreement are secured by a first priority security interest in substantially all of its assets other than its intellectual property. The Company has also agreed not to pledge or otherwise encumber its intellectual property assets, subject to certain exceptions. In connection with the Loan Agreement, the Company issued to the Lender and its affiliates warrants to purchase a total of 2,492,523 shares of common stock at an exercise price of $0.1003 per share, which the Company refers to herein as the Lender Warrants. The Lender Warrants have a term of ten (10) years.

7

 The Company’s financial statements have been prepared assuming that it will continue as a going concern which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The financial statements do not include any adjustments that might result from the outcome of this uncertain realization. The Company expects to incur additional losses in 2015 and, accordingly, is dependent on financings and potential revenue to fund its operations and support the market adoption of the PerioPredict^® test. The timing of any revenues that the Company may receive from the PerioPredict^® test is uncertain at this time, and is contingent upon a number of factors, including the Company’s ability to consummate arrangements with partners to promote the PerioPredict^® test, the Company and its partners’ ability to develop insurance plans that provide for use and reimbursement of the PerioPredict^® test, or other possible arrangements, and to develop a viable market for such plans, and the timing of utilization of the PerioPredict^® test pursuant to such plans. The Company expects to have the cash resources necessary to fund its operations for at least the next twelve months.

The ability of the Company to realize the carrying value of its fixed assets and intangible assets is dependent on management’s ability to successfully execute on its plan. The Company needs to generate additional funds in order to meet its financial obligations. If it is unsuccessful in doing so, the Company may not be able to realize the carrying value of its fixed assets and intangible assets.

Note 3—Summary of Significant Accounting Policies

Management Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenue and expenses during the reported periods. Actual results could differ from those estimates. The Company’s most critical accounting policies are more fully discussed in these notes to the financial statements.

Revenue Recognition

Revenue from genetic testing services is recognized when there is persuasive evidence of an arrangement, service has been rendered, the sales price is determinable and collectability is reasonably assured. Service is deemed to be rendered when the results have been reported to the individual who ordered the test. To the extent that tests have been prepaid but results have not yet been reported, recognition of all related revenue is deferred. As of June 30, 2015 and December 31, 2014, the Company had deferred genetic test revenue of $3.0 million and $3.2 million, respectively. Included in deferred revenue at June 30, 2015 is $2.9 million for test kits that are still outstanding one year or longer after initial kit sale, of which $0.5 million was sold directly to consumers (credit card payments) and $2.4 million was sold to distributors for the Body Key promotional bundle.

The Company recognizes breakage revenue related to genetic test kits utilizing the remote method. Under the remote method, breakage revenue should be recognized when the likelihood of the customer exercising rights of redemption becomes remote. The term remote requires statistical analysis of customer redemption patterns for all tests sold and returned. The Company analyzed redemption patterns from 2009 through 2014 and determined the period of time after which the likelihood of test redemption was remote was three years after the sale of a genetic test kit. Included in genetic test revenue in the three and six months ended June 30, 2015 is $52,305 and $128,205, respectively, of breakage revenue related to unredeemed genetic test kits sold in the first and second quarters of 2012, compared to breakage revenue included in genetic test revenue in the three and six months ended June 30, 2014 of $92,364 and $156,861, respectively, related to unredeemed genetic test kits sold in the first and second quarters of 2011. The Company expects to continue to recognize breakage revenue on a quarterly basis based on the historical analysis.

Sales Commission

On October 26, 2009, the Company entered into a Merchant Network and Channel Partner Agreement with Amway Corp., d/b/a/ Amway Global (“Amway Global”), a subsidiary of Alticor Inc. (“Alticor”). Pursuant to this Agreement, Amway Global sells the Company’s Inherent Health^® brand of genetic tests through its e-commerce website via a hyperlink to our e-commerce site. The Company accounts for sales commissions due to Amway Global under the Merchant Network and Channel Partner Agreement in accordance with SEC Staff Accounting Bulletin (“SAB”) 104. Commissions are recorded as an expense at the time they become due which is at the point of sale. The cost of commissions was $80,000 and $59,000 for the three months ended June 30, 2015 and 2014, respectively, and $168,000 and $101,000 for the six months ended June 30, 2015 and 2014, respectively.

Accounts Receivable

Accounts receivable is stated at estimated net realizable value, which is generally the invoiced amount less any estimated discount related to payment terms. The Company offers its commercial genetic test customers a 2% cash discount if payment is made by bank wire transfer within 10 days of the invoice date. No accounts receivable reserve is required at June 30, 2015 as all accounts receivable are expected to be collected.

Inventory

Inventory is carried at lower of cost (first-in, first-out method) or market and no inventory reserve is deemed necessary at June 30, 2015. As the Company does not manufacture any products, no overhead costs are included in inventory. The Company has contracted with a fulfillment provider to supply its PerioPredict^® genetic tests kits to dental offices. The agreement with the provider provides that the vendor will purchase and fulfill all materials related to the PerioPredict^® test and Body Key™ genetic test kits, with the Company’s approval. The Company pays for materials and fulfillment charges when the product is shipped. During the six months ended June 30, 2015, the Company purchased $33,000 of inventory related to its PerioPredict^® test, which is held at our fulfillment center. When a kit is sold, the corresponding cost of the kit is recorded as deferred cost of goods sold and removed from inventory. Any kit components remaining at the fulfillment center are reflected in inventory with a corresponding offset to accounts payable. At December 31, 2014 $48,000 of raw materials were at the fulfillment center and reflected in inventory with a corresponding entry to accounts payable.

Inventory consisted of the following:

	June 30, 2015		December 31, 2014
Raw materials	$	150,123	$	163,239
Finished goods		8,925		8,336
Total inventory, net	$	159,048	$	171,575

Stock-Based Compensation

The Company accounts for stock-based compensation expense in accordance with FASB ASC 718, Compensation – Stock Compensation. The standard addresses all forms of share-based payment (SBP) awards, including shares issued under employee stock purchase plans, stock options, restricted stock and stock appreciation rights. We expense SBP awards within compensation cost for SBP transactions measured at fair value. Compensation cost for the portion of awards for which the requisite service has not been rendered that are outstanding as of the effective date shall be recognized as the requisite service is rendered on or after the effective date. The compensation cost for that portion of awards shall be based on the grant-date fair value of those awards as calculated under the Black-Scholes option pricing model. Common stock purchased pursuant to our employee stock purchase plan will be expensed based upon the fair market value in excess of purchase price.

Income Taxes

The Company accounts for income taxes in accordance with FASB ASC 740, Income Taxes, which requires the recognition of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in the financial statements or tax returns. The measurement of current and deferred tax liabilities and assets is based on provisions of the enacted tax law; the effects of future changes in tax laws or rates are not anticipated. The Company records a valuation allowance to reduce its deferred tax assets to the amount that is more likely than not to be realized.

9

Significant management judgment is required in determining the Company’s provision (benefit) for income taxes, its deferred tax assets and liabilities and any valuation allowance recorded against deferred tax assets. The Company has recorded a full valuation allowance against its deferred tax assets of approximately $33.4 million as of June 30, 2015, due to uncertainties related to its ability to utilize these assets. The valuation allowance is based on management’s estimates of taxable income by jurisdiction in which the Company operates and the period over which the deferred tax assets will be recoverable. In the event that actual results differ from these estimates or management adjusts these estimates in future periods, the Company may need to adjust its valuation allowance, which could materially impact its financial position and results of operations.

As a result of the Company’s change in its capital structure during the quarters ending June 30, 2013 and December 23, 2014, the Company may have undergone an IRC section 382 ownership change which would limit its ability to realize the benefit of its tax attributes (i.e., federal/state net operating losses and research and development credits) during their respective carry forward periods. Furthermore, pursuant to the change in capital structure, the Company realized cancellation of indebtedness income under IRC section 108(e)(8), which reduced the Company’s federal net operating loss carry-forward pursuant to IRC section 108(b)(2)(A), due to the fact that the Company’s liabilities exceeded the fair market value of its assets. Accordingly, the Company had a reduction in its deferred tax asset and a corresponding reduction in its valuation allowance for the quarter ending June 30, 2013. The cancellation of indebtedness income resulted from a shareholder’s conversion of debt of approximately $14.3 million into common stock of the Company prior to an additional investment by an unrelated investor.

The Company reviews its recognition threshold and measurement process for recording in the financial statements uncertain tax positions taken or expected to be taken in a tax return. The Company reviews all material tax positions for all years open to statute to determine whether it is more likely than not that the positions taken would be sustained based on the technical merits of those positions. The Company did not recognize any adjustments for uncertain tax positions as of and during the six months ended June 30, 2015.

Research and Development

Research and development costs are expensed as incurred.

Basic and Diluted Net Loss per Common Share

The Company applies the provisions of FASB ASC 260, Earnings per Share, which establishes standards for computing and presenting earnings per share. Basic and diluted net loss per share was determined by dividing net loss applicable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted net loss per share is the same as basic net loss per share for all the periods presented, as the effect of the potential common stock equivalents is anti-dilutive due to the loss in each period. Potential common stock equivalents excluded from the calculation of diluted net loss per share are as follows:

	As of June 30,

Fair Value of Financial Instruments

The Company, using available market information, has determined the estimated fair values of financial instruments. The stated values of cash and cash equivalents, accounts receivable and accounts payable approximate fair value due to the short-term nature of these instruments. The fair value of warrants is calculated using the Black-Scholes pricing model.

Cash and Cash Equivalents

The Company maintains its cash and cash equivalents with domestic financial institutions that the Company believes to be of high credit standing. The Company believes that, as of June 30, 2015, its concentration of credit risk related to cash and cash equivalents was not significant. Cash and cash equivalents are available on demand and are generally in excess of FDIC insurance limits.

Fixed Assets

Fixed assets are stated at cost, less accumulated depreciation and amortization. Depreciation and amortization are provided using the straight-line method over estimated useful lives of three to five years. Leasehold improvements are amortized over the shorter of the estimated useful life of the asset or the remaining term of the lease.

Assets that have not yet been placed in service, have the costs incurred presented as part of Projects in Progress. Once the asset has been placed in service, the related costs are transferred to the appropriate category and depreciation commences. For the six months ended June 30, 2015 there is no balance in the Projects in Progress account.

Segment Reporting

As of June 30, 2015 and 2014, the Company has one segment, the genetic test business. The Company develops genetic tests for sale into the emerging personalized health market and performs testing services that can help individuals improve and maintain their health through preventive measures. The Company’s principal operations and markets are located in the United States.

Recent Accounting Pronouncements

FASB ASU 2015-03 - Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.

In April 2015, the FASB issued ASU No. 2015-03, which requires that debt issuance costs be reported in the balance sheet as a direct deduction from the face amount of the related liability, consistent with the presentation of debt discounts.  Prior to the amendments, debt issuance costs were presented as a deferred charge (i.e., an asset) on the balance sheet.  Further, the amendments require the amortization of debt issuance costs to be reported as interest expense. Similarly, debt issuance costs and any discount or premium are considered in the aggregate when determining the effective interest rate on the debt. The amendments are effective for public business entities for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The amendments must be applied retrospectively. All entities have the option of adopting the new requirements as of an earlier date for financial statements that have not been previously issued. The Company does not expect this ASU to have a material impact on its consolidated financial statements.

FASB ASC 606 ASU 2014-09 - Revenue from contracts with customers.

In May 2014, the FASB issued amended guidance on contracts with customers to transfer goods or services or contracts for the transfer of nonfinancial assets, unless those contracts are within the scope of other standards (e.g., insurance contracts or lease contracts). The guidance requires an entity to recognize revenue on contracts with customers 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. The guidance requires that an entity depict the consideration by applying the following five steps:

· Identify the contract(s) with a customer.

· Identify the performance obligations in the contract.

· Determine the transaction price.

· Allocate the transaction price to the performance obligations in the contract.

· Recognize revenue when (or as) the entity satisfies a performance obligation.

The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. This amendment is to be either retrospectively adopted to each prior reporting period presented or retrospectively with the cumulative effect of initially applying this ASU recognized at the date of initial application.

In April, 2015 the FASB voted to defer the required implementation date of ASU 2014-09 to December 2017. Public companies may elect to adopt the standard along the original timeline. We are evaluating the impact of the adoption of this guidance to determine whether or not it has a material impact on the Company's financial statements.

FASB ASC 606 ASU 2014-15 - Presentation of Financial Statements—Going Concern (Subtopic 205-40); Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.

In August 2014, the FASB issued ASU No. 2014-15, which applies should a company be facing probable liquidation within one year of the issuance of the financial statements, but is not actually in liquidation at the time of issuance.  The applicable basis for presentation remains as a going concern, but if liquidation within one year is probable, then certain disclosures must be included in the financial statement presentation.  ASU 2014-15 is effective for annual and interim periods beginning after December 15, 2016, with early adoption permitted. We are evaluating the impact of ASU 2014-15 on our financial disclosures, but are not electing early adoption at this time.

Note 4—Related Party Transactions

Since March 2003, the Company has maintained a broad strategic alliance with several affiliates of the Alticor Inc. family of companies, a related party. The alliance initially included an equity investment, a multi-year research and development agreement, a licensing agreement with royalties on marketed products, the deferment of outstanding loan repayment and the refinancing of bridge financing obligations.

On October 26, 2009, the Company entered into a Merchant Network and Channel Partner Agreement with Amway Corp., d/b/a/ Amway Global (“Amway Global”), a subsidiary of Alticor Inc. Pursuant to this Agreement, Amway Global sells the Company’s Inherent Health^® brand of genetic tests through its e-commerce website via a hyperlink to the Company’s e-commerce site. The Company paid Amway Global $80,000 and $59,000 in commissions for the three months ended June 30, 2015 and 2014, respectively, and $168,000 and $101,000 in commissions for the six months ended June 30, 2015 and 2014, respectively, representing a percentage of net sales to their customers. The Company expenses commissions owed to Amway Global in the month of sale to the customer.

Beginning in September 2012 and again in 2013, Access Business Group LLC (“ABG”), an affiliate of Alticor, placed purchase orders totaling approximately $3.3 million consisting of Weight Management test kits. The kits are included as part of a promotional bundle of products that Amway is now selling to their Individual Business Owners (IBOs). Of the $3.3 million in orders, $1.5 million was received for the 2013 program and $1.8 million for the 2014 program. As a component of the 2013 promotional program, and not reflective of actual product expiry, the kits were required to be redeemed by December 31, 2013. In February 2014, the Company removed the redemption date requirement for the 2013 promotional program, for which ABG paid the Company $519,000 as a retrospective increase in the product purchase price. All cash received related to the 2013 promotional program, including the $519,000, will be treated as deferred revenue until specific kits are returned for processing or the breakage analysis determines the probability of eventual redemption is remote. In October 2014, the Company received $250,000 as a retrospective increase in the product purchase price for unsold kits as consideration for extending the required redemption date of the 2014 promotional program to December 31, 2017. All cash received for these kits will be treated as deferred revenue until specific kits are returned for processing or on the final allowed redemption date of December 31, 2017.

On September 21, 2012, the Company entered into a License Agreement with Access Business Group International LLC (“ABGI”), an affiliate of Alticor. Pursuant to the License Agreement, the Company has granted ABGI and its affiliates a non-exclusive license to use the technology related to Interleukin’s Weight Management genetic test and to sell the Weight Management test in Europe, Russia and South Africa (the “Territories”). ABGI, or a laboratory designated by ABGI, will be responsible for processing the tests, and the Company will receive a royalty for each test sold, which royalty will increase if certain pending patent applications are issued. The License Agreement has an initial term of five years from the date of first commercial sale of the Weight Management test under the agreement which was June 2013. Thereafter, the term will automatically renew for additional one-year periods unless notice is delivered by either party at least 60 days prior to the anniversary date. During the three and six months ended June 30, 2015, $49,000 and $103,203, respectively, was earned, compared to $43,000 and $97,885 in the same periods in 2014

In connection with the execution of the License Agreement, the Company and ABGI also entered into a Professional Services Agreement (the “PSA”) pursuant to which the Company has agreed to provide services to ABGI in connection with its sale and processing of the tests within the Territories. No fees were earned in the year ended December 31, 2014 or the six months ended June 30, 2015 under the PSA.

For the three months ended June 30, 2015 and 2014, approximately 46% and 39%, respectively, of the Company’s revenue came from sales through the Merchant Network and Channel Partner Agreement with Amway Global, and 16% and 38%, respectively, of the Company’s revenue came from sales through ABG’s promotional product bundle program. For the six months ended June 30, 2015 and 2014, approximately 51% and 37%, respectively, of the Company’s revenue came from sales through the Merchant Network and Channel Partner Agreement with Amway Global, and 15% and 38%, respectively, of the Company’s revenue came from sales through ABG’s promotional product bundle program.

On February 25, 2013, the Company entered into a Preferred Participation Agreement with Renaissance Health Services Corporation (“RHSC”), for itself and on behalf of certain of its affiliates and subsidiaries. RHSC is a related party through its affiliation with Delta Dental of Michigan, Inc. (“DDMI”), a stockholder of the Company. Pursuant to this agreement, affiliates of RHSC agreed to reimburse the Company a fixed price for each PerioPredict^® genetic test that the Company processed for a customer of affiliates of RHSC. In addition, if during the term of the agreement the Company offered the PerioPredict^® test to any other person or party for a lower price, such lower price would then be applicable to tests processed for a customer of affiliates of RHSC for the remainder of the term of the agreement. The pricing arrangement was subject to the satisfaction of certain milestones, including that (1) within a specified timeframe, RHSC affiliates were to develop and offer dental benefit plans for which a significant portion of such affiliate's clients are eligible that provided for use of the PerioPredict^® test and reimbursement of the test at the agreed upon price (each such plan, hereinafter referred to as a “Reimbursed Dental Plan”) and (2) prior to a specified date, RHSC affiliates were to have sold policies for Reimbursed Dental Plans for the year beginning January 1, 2014. The Company agreed that for a one year period beginning on the date on which RHSC affiliates first offered a Reimbursed Dental Plan, it would make the PerioPredict^® test available solely to RHSC affiliates and not to any other third party or person. This agreement had a term of three years beginning on February 25, 2013.

On November 1, 2013, the Company entered into an Amended and Restated Preferred Participation Agreement with RHSC, for itself and on behalf of certain of its affiliates and subsidiaries. Pursuant to this agreement, affiliates of RHSC have agreed to reimburse the Company a fixed price for each PerioPredict^® genetic test that the Company processes for a customer of affiliates of RHSC. In addition, if during the term of the agreement the Company offers the PerioPredict^® test to any other person or party for a lower price, such lower price shall then be applicable to tests processed for a customer of such affiliates of RHSC for the remainder of the term of the agreement. RHSC and its affiliates will continue to receive the preferred pricing (or any lower market price during the term) only for so long as affiliates of RHSC continue to: (a) work to develop and to offer Reimbursed Dental Plans for which a significant portion of employees of RHSC’s affiliates’ customers are eligible; and (b) exercise their commercially-reasonable best efforts to maximize the number of customers that offer a Reimbursed Dental Plan. In addition, under the terms of the amended agreement, the Company is no longer obligated to make the PerioPredict^® test available solely to RHSC affiliates and not to any other third party or person. This amended agreement has a term of three years beginning February 25, 2013, unless terminated earlier (1) upon the mutual written agreement of us and RHSC, (2) if either party becomes the subject of bankruptcy, insolvency, liquidation or other similar proceedings, or (3) in the event of an uncured breach of the amended agreement by either party.

The timing of any revenues that the Company may receive under the amended agreement with RHSC is dependent upon the timing of the offering of Reimbursed Dental Plans and the subsequent adoption of such Reimbursed Dental Plans by RHSC customers, the timing of which is very uncertain at this time and is dependent on a viable market developing for such plans. RHSC has informed us that it has presented the scientific data underlying Reimbursed Dental Plans to a number of customers and will make available Reimbursed Dental Plans as an alternative to a customer’s current plan for any customer that expresses an interest in such a plan. The Company may never receive significant revenues under this agreement.

Venture Loan and Security Agreement

On December 23, 2014, the Company entered into the Loan Agreement with Horizon Technology Finance Corporation (the “Lender”) under which the Company borrowed $5.0 million. The loan bears interest at a floating rate equal to the One Month LIBOR Rate (with a floor of 0.50%) plus 8.50%. In the event that the One Month LIBOR Rate, as reported in the Wall Street Journal, exceeds 0.50%, the interest rate will be adjusted by an amount equal to the difference between such rates at the end of that particular month. At June 30, 2015, the rate was 9.0% per annum. The loan is to be repaid in forty-five (45) monthly payments consisting of fifteen (15) monthly payments of only interest followed by thirty (30) equal monthly payments of principal and interest. In addition, at the end of the repayment term (or at early termination of the loan) a final payment equal to 4.5% of the loan, or $225,000, will be due and payable. The Company’s obligations under the Loan Agreement are secured by a first priority security interest in substantially all of its assets other than its intellectual property. The Company has also agreed not to pledge or otherwise encumber its intellectual property assets, subject to certain exceptions. In connection with the Loan Agreement, the Company issued to the Lender and its affiliates warrants to purchase a total of 2,492,523 shares of common stock at an exercise price of $0.1003 per share, which the Company refers to herein as the Lender Warrants.

Additionally, $88,918 in cash fees paid to the Lender and $261,386, the intrinsic value of the Lender Warrants, were recorded as a discount on the loan and amortized over the term of the loan. The final non-principal payment of $225,000 will be accrued as additional interest expense, using the effective interest method, over the term of the loan. As of June 30, 2015, the unamortized discount associated with the loan was $303,597. Cash interest expense for the three and six months ending June 30, 2015 was $113,750 and $226,250, respectively. Non-cash interest expense for the three and six months ending June 30, 2015 was $38,354 and $76,707, respectively.

For services related to this transaction, the placement agent and legal counsel received an aggregate of $218,126 in cash fees and the placement agent and an affiliate received warrants to purchase an aggregate of 89,731 shares of common stock (the “2014 Placement Agent Warrants”). The cash fees and the fair value of the 2014 Placement Agent Warrants were recorded as equity issuance costs resulting in a reduction to shareholders’ equity.

The 2014 Warrants (and the 2014 Placement Agent Warrants) were recorded as equity at fair value on the date of issuance. Fair value of the 2014 Warrants (and the 2014 Placement Agent Warrants) was calculated using the following inputs in a Black-Scholes model:

	December 23, 2014
Risk-free interest rate		1.98	%
Expected life		7 years
Expected volatility		138.4	%
Dividend yield		0	%

On the closing date of the December 2014 Private Placement, the fair value of the 2014 Warrants was $5.2 million, and the fair value of the 2014 Placement Agent Warrants was $9,000.

Registration Rights Agreement

In connection with the December 2014 Private Placement, on December 23, 2014, the Company also entered into a Registration Rights Agreement with the 2014 Investors and the placement agent, pursuant to which the Company was required to file a registration statement on Form S-1 within 45 days of December 23, 2014 to cover the resale of (i) the shares of common stock sold to the 2014 Investors and the shares of common stock underlying the 2014 Warrants and (ii) the shares of common stock underlying the 2014 Placement Agent Warrants. The Company filed the registration statement on February 6, 2015, and it was declared effective on March 31, 2015.

Venture Loan and Security Agreement

On December 23, 2014, the Company entered into the Loan Agreement with Horizon Technology Finance Corporation (the “Lender”) under which the Company has borrowed $5.0 million. In connection with the Loan Agreement, the Company issued to the Lender and its affiliates Lender Warrants to purchase a total of 2,492,523 shares of common stock at an exercise price of $0.1003 per share. The Lender Warrants have a term of ten (10) years.

The Lender Warrants were recorded as equity at fair value on the date of issuance. Fair value of the Lender Warrants was calculated using the following inputs in a Black-Scholes model:

18

Stock Option Grants

On August 9, 2013, the Company’s shareholders’ approved the 2013 Employee, Director and Consultant Equity Incentive Plan (the “2013 Plan”). The 2013 Plan allows for the issuance of up to 8,860,000 additional shares of our common stock pursuant to awards granted under the 2013 Plan. Additionally, the 2013 plan allows for the issuance of up to a maximum of 2,435,500 additional shares of our common stock, pursuant to the cancellation, forfeiture, or expiry, of awards granted under the 2004 Plan and terminated on or after the 2013 plan approval on August 9, 2013. During the six month period ended June 30, 2015, the Company granted 6,156,748 stock options under the 2013 Plan. At June 30, 2015, the Company had an aggregate of 22,412 shares of common stock available for grant under the 2013 Plan. On July 21, 2015, the Company’s stockholders approved an amendment to the 2013 Plan to increase the number of shares of common stock available for issuance thereunder by 30,000,000 shares.

Pursuant to his Employment Agreement on April 6, 2015, Mr. Carbeau has been granted options to purchase up to 14,245,227 shares of Interleukin’s common stock at an exercise price of $0.1525 per share (the closing price of the common stock on April 6, 2015). Of those options, 2,622,948 were granted under the 2013 Plan and 11,622,279 were granted outside of the 2013 Plan. The Options will vest as to 25% of the shares on April 6, 2016, and as to an additional 2.083% of the shares on the last day of each successive month thereafter, provided that he remains employed by Company on the vesting date.

It is the Company’s policy to grant stock options with an exercise price equal to the fair market value of the Company’s common stock at the grant date, and stock options to employees generally vest over four years based upon continuous service. Historically, the majority of the Company’s stock options have been granted in connection with the employee’s start date with the Company. In addition, the Company may grant stock options in recognition of promotion and/or performance.

Employee Stock Purchase Plan

Purchases made under the Company’s Employee Stock Purchase Plan are deemed to be compensatory because employees may purchase stock at a price equal to 85% of the fair market value of the Company’s common stock on either the first day or the last day of a calendar quarter, whichever is lower. During the six months ended June 30, 2015 and 2014, employees purchased 103,565 and 67,610 shares, respectively, of common stock at a weighted-average purchase price of $0.11 and $0.29, respectively, while the weighted-average market value was $0.13 and $0.34 per share, respectively, resulting in compensation expense of $2,041 and $3,450, respectively.

Note 9—Industry Risk and Concentration

The Company develops genetic risk assessment tests and performs research for its own benefit. As of June 30, 2015, the Company sells five genetic risk assessment tests. Commercial success of the Company’s genetic risk assessment tests will depend on their success as being deemed to be scientifically credible and cost-effective by consumers and the marketing success of the Company and its collaborative partners.

Research in the field of disease predisposing genes and genetic markers is intense and highly competitive. The Company has many competitors in the United States and abroad that have considerably greater financial, technical, marketing, and other resources available. If the Company does not discover disease predisposing genes or genetic markers and develop risk assessment tests and launch such services or products before its competitors, then the potential for significant revenues may be reduced or eliminated.

During the three months ended June 30, 2015 and 2014, approximately 46% and 39%, respectively, of the Company’s revenue came from sales through the Merchant Network and Channel Partner Agreement with Amway Global, and 16% and 38%, respectively, of the Company’s revenue came from sales through ABG’s promotional product bundle program. During the six months ended June 30, 2015 and 2014, approximately 51% and 37%, respectively, of the Company’s revenue came from sales through the Merchant Network and Channel Partner Agreement with Amway Global, and 15% and 38%, respectively, of the Company’s revenue came from sales through ABG’s promotional product bundle program.

Note 10—Subsequent Events

On July 21, 2015, the Company’s shareholders’ approved an amendment to the Company’s Restated Certificate of Incorporation to increase the number of authorized shares of common stock from 300,000,000 to 450,000,000, and the Company filed a certificate of amendment with the Delaware Secretary of State which was effective on July 21, 2015. The Company’s shareholders’ also approved an amendment to the Company’s Restated Certificate of Incorporation to effect a reverse stock split by combining outstanding shares of the Company’s common stock into a lesser number of outstanding shares by a ratio of not less than 1-for-5 and not more than 1-for-40 at any time prior to the earlier of (i) August 1, 2016 and (ii) the 2016 annual meeting of shareholders’, with the exact ratio to be set within this range by the Company’s Board of Directors in its sole discretion. The Company’s shareholders’ also approved an amendment to the Company’s 2013 Employee, Director and Consultant Equity Incentive Plan to increase the number of shares of common stock available for issuance thereunder by 30,000,000 shares. The total number of shares available following the amendment is 30,022,412.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion of our financial condition and results of operations should be read in conjunction with the unaudited condensed financial statements and the notes thereto included elsewhere in this document.

General Overview and Trends

Interleukin Genetics, Inc. is a personalized health company that develops specific, health area focused, unique genetic tests. Our overall mission is to provide test products that can help individuals improve or maintain their health through preventive or treatment measures. Our vision is to use the science of applied genetics to empower individuals and physicians to better understand the actions and steps necessary to guide the best lifestyle and treatment options. We believe that Interleukin Genetics’ tests can help individuals and their healthcare providers more effectively prevent common diseases of aging and their complications and thereby extend an individual’s years of wellness. Our tests also provide our commercial partners with technologies that can improve services to their consumers.

During the three months ended June 30, 2015, we continued to focus our resources primarily on commercializing our PerioPredict^® test, as well as on the sales of our Inherent Health^® brand of genetic tests and related programs. As part of that effort, we appointed Mark B. Carbeau, a transformative healthcare leader and entrepreneur with more than three decades of business expertise in the life sciences industry and a proven track record of building high-growth diagnostic and pharmaceutical businesses, as Chief Executive Officer and Director on April 6, 2015.

The clinical utility of the PerioPredict^® test is supported by the large validation study conducted by the University of Michigan and referred to as the Michigan Personalized Prevention Study, or MPPS. The objective of the MPPS is to improve dental care by identifying and using certain risk factors to set preventative treatment regimens. On August 6, 2012, we announced that we had received top line results from the MPPS, and on June 10, 2013, we announced the publication of the MPPS results in the Journal of Dental Research. The study examined data from 5,117 patients monitored for 16 consecutive years. These results indicate that in Low Risk patients (those with none of three risk factors: smoking, diabetes, and PerioPredict^®) there was no significant difference between two dental preventive visits per year and one preventive visit per year in the percentage of patients who had tooth extractions over the 16 year monitoring period; 13.8% versus 16.4%, respectively. In addition, these results indicate that in High Risk patients (those with any one of the three risk factors, with PerioPredict^® being the most common of the three), two preventive visits per year significantly reduced the percentage of patients who had extractions over a 16 year monitoring period compared to one preventive visit per year; 16.9% vs. 22.1%. There was also a positive relationship between number of risk factors and the percentage of patients with extractions. For patients with two or three risk factors, and smoking plus PerioPredict^® positive represented approximately 67% of those patients, two cleanings annually did not appear to be sufficient to control risk for tooth loss.

There is also increasing evidence that the PerioPredict^® test enables the identification of patients who may be at higher risk for increased systemic inflammation, which is implicated in a variety of chronic diseases, such as diabetes and coronary artery disease, as well as periodontitis. Such high-risk patients may be responsive to greater preventive dental care in managing these chronic conditions. We believe that significant improvement in patient care and reduced medical expenses can be achieved by stratifying patient risk for these chronic inflammatory conditions through PerioPredict^® testing, combined with cost-effective dental intervention; for example, one to two additional annual cleanings.

We believe the use of the PerioPredict^® test to identify patients who may be responsive to a cost-effective dental intervention is a compelling value proposition, and are engaged in discussions with a number of relevant parties with an interest in reducing costs and improving patient care, including medical and dental insurers, large and small employers and benefits brokers and consultants, regarding implementing PerioPredict^® testing, both directly and through our partner, Employee Benefit Consulting Group LLC (EBCG), with whom we entered a collaboration agreement on March 30, 2015 to help expand knowledge and potential coverage for PerioPredict^®.  We believe this collaboration will help us leverage genetic testing as part of an approach to more effective overall healthcare management.  Under the terms of this strategic collaboration, we will work together with EBCG to build awareness of PerioPredict^® as a tool for personalizing patient care among insurance carriers, benefit plans and employer groups, and to potentially incorporate the test in the design of risk-based benefit plans. 

20

On February 25, 2013, we entered into a Preferred Participation Agreement with RHSC, for itself and on behalf of certain of its affiliates and subsidiaries, which was amended and restated on November 1, 2013. Pursuant to this agreement, affiliates of RHSC have agreed to reimburse us a fixed price for each PerioPredict^® genetic test that we process for a customer of affiliates of RHSC. The timing of any revenues that we may receive under the Amended and Restated Preferred Participation Agreement (the “Preferred Participation Agreement”) with RHSC is dependent upon the timing of the offering of dental benefit plans that provide for use of the PerioPredict^® test and reimbursement of the test (each such plan, hereinafter referred to as a “Reimbursed Dental Plan”), which timing is very uncertain at this time and is dependent on a viable market developing for such plans. RHSC has informed us that it has presented the scientific data underlying Reimbursed Dental Plans to a number of customers and will make available Reimbursed Dental Plans as an alternative to a customer’s current plan for any customer that expresses an interest in such a plan. The timing of any such revenues under this agreement is uncertain and we may never receive significant revenues under this agreement.

On April 11, 2014, we announced the pre-print online publication of our research study titled “Association of interleukin-1 gene variations with moderate to severe chronic periodontitis in multiple ethnicities” in the Journal of Periodontal Research. The study results from multiple ethnic groups further validated the association between periodontitis and the interleukin-1 beta (IL1B) composite genotype pattern, a specific genetic profile that can be elucidated by our PerioPredict^® genetic risk test. In addition, the study results demonstrated that detection of the IL1B variations tested provided added value in the prediction of moderate to severe periodontitis above and beyond the risk attributable to smoking and diabetes alone.

On April 22, 2014, we announced receipt of conditional approval from the New York State Department of Health to offer, process and report the results of the PerioPredict^® test for periodontal disease.  The State of New York is the only U.S. state that requires an independent regulatory review process including technical validation with clinical utility for laboratory developed tests run within a CLIA certified laboratory. Conditional status will be removed on successful completion of a future additional review, the timing of which is determined solely by the State of New York. As a result of New York State approval the PerioPredict^® test is now available to dental providers and their patients in all 50 U.S. states.  

The PerioPredict^® test is solely available through Interleukin Genetics. The web site for the PerioPredict^® test is www.PerioPredict.com. We will continue to engage in discussions that may lead to increased adoption of our PerioPredict^® test but the timing of any such adoption is uncertain at this time, and may never occur.

Our Inherent Health^® brand of genetic tests includes the first-of-its-kind test for weight management that identifies an individual’s genetic tendencies for weight gain related to either fat or carbohydrates in the diet. The Inherent Health^® brand also offers customers a full suite of affordable, easy-to-use and meaningful genetic tests in heart health, bone health and nutritional needs. In addition, we launched additional products under the name Wellness Select that allows our e-commerce customers to purchase any combination of our Inherent Health® genetic tests at a discounted price.

A recently published paper in the Journal of the American College of Cardiology (Tsimikas et al. 2014) extends the scientific evidence supporting the value of Interleukin Genetics’ proprietary Heart Health test to improve the identification of individuals with a prior diagnosis of cardiovascular disease who are at increased risk for a future cardiovascular disease event. This test has the potential to change a physician’s clinical actions to better manage cardiovascular disease risk. We believe this test may be most appropriately applied in the future to guide use of drugs currently in development by others that directly address the biological mechanisms identified by our test.

We market our Inherent Health^® brand of genetic assessment tests primarily through our commercial relationships with Alticor Inc. affiliated companies. Alticor is a related party. On October 26, 2009, we entered into a Merchant Network and Channel Partner Agreement with Amway Corp., d/b/a/ Amway Global (“Amway Global”), a subsidiary of Alticor. Pursuant to this agreement, Amway Global sells our Inherent Health^® brand of genetic tests through its e-commerce website via a hyperlink to our e-commerce site. In the three months ended June 30, 2015 and 2014, revenues from this agreement accounted for approximately 46% and 39% of our revenues, respectively. In the six months ended June 30, 2015 and 2014, revenues from this agreement accounted for approximately 51% and 37% of our revenues, respectively.

21

Beginning in September 2012 and again in 2013, Access Business Group LLC (“ABG”), an affiliate of Alticor, placed purchase orders totaling approximately $3.3 million consisting of Weight Management kits. The kits are included as part of a promotional bundle of products that Amway is now selling to their Individual Business Owners (IBOs). Of the $3.3 million in orders $1.8 million was received in 2013 for the 2014 program and $1.5 million for the 2013 program. All cash for the orders and royalties was received by December 31, 2013. The 2013 program was amended by ABG so that it would not expire at December 31, 2013. Rather than having all program kits expire at December 31, 2013, cash received from the orders will remain in deferred revenue until the tests are returned and processed. For the three months ended June 30, 2015 and 2014, approximately 16% and 38%, respectively, of our revenue came from sales through ABG’s promotional product bundle program. For the six months ended June 30, 2015 and 2014, approximately 15% and 38%, respectively, of our revenue came from sales through ABG’s promotional product bundle program.

On September 21, 2012, we entered into a License Agreement with Access Business Group International LLC (“ABGI”), an affiliate of Alticor. Pursuant to this License Agreement, we granted ABGI and its affiliates a non-exclusive license to use the technology related to our Weight Management genetic test and to sell the Weight Management test in Europe, Russia and South Africa. ABGI, or a laboratory designated by ABGI, is responsible for processing the tests, and we receive a royalty for each test sold. The License Agreement has an initial term of five years from the date of first commercial sale of the Weight Management test under the agreement which was June 2013. During the three and six months ended June 30, 2015, royalties of $49,000 and $103,203, respectively, were received and recorded as Other Revenue in the Condensed Statement of Operations.

Our research and development efforts, and related expenses, are focused on expanding the evidence supporting our existing tests, primarily our PerioPredict^® test. This is different than in prior years, when our research and development focus was concentrated on bringing new tests to market.

We recognize revenue from genetic testing services when there is persuasive evidence of an arrangement, service has been rendered, the sales price is determinable and collectability is reasonably assured. Service is deemed to be rendered when the results have been reported to the individual who ordered the test. To the extent that tests have been prepaid but results have not yet been reported, recognition of all related revenue is deferred. During the fourth quarter of 2013, we concluded that sufficient historical customer genetic test redemption patterns existed to determine the period of time after which the likelihood of test redemption was remote for Inherent Health^® tests purchased. Based on our analysis of the redemption data, we estimate that period of time to be three years after the sale of a genetic test kit. Prior to making this determination, revenue was recognized only on test kits returned and processed. Beginning in the fourth quarter of 2013, we began to recognize breakage revenue related to genetic tests kits utilizing the remote method. Under the remote method, breakage revenue should be recognized when the likelihood of the customer exercising rights of redemption becomes remote. The term remote requires statistical analysis of customer redemption patterns for all tests sold and returned. We analyzed redemption patterns from 2009 through 2013. Included in genetic test revenue in the three and six months ended June 30, 2015, is $52,305 and $128,205, respectively, of breakage revenue related to unredeemed genetic test kits from the first and second quarters of 2012, respectively, compared to $92,364 and $156,861 in the same periods in 2014 related to unredeemed genetic test kits from the first and second quarters of 2011, respectively. We will continue to recognize breakage revenue and the corresponding deferred cost of goods as well as analyze the data on a quarterly basis based on the historical analysis.

In the genetic test business, competition is in flux and the markets and customer base are not well established. Adoption of new technologies requires substantial market development and customer education. Historically, we have focused on our relationship with our primary customer, Alticor, a significant direct marketing company, in order to assist us in developing the market for our products, primarily the Inherent Health^® line of tests, and educating our potential customers. Our challenge in the remainder of 2015 and beyond will be to develop the market for our other personalized health products, in particular our PerioPredict^® test. We continue to allocate considerable resources to commercialization of our PerioPredict^® and Inherent Health^® brands of genetic tests. Due to the early stage of these initiatives, we cannot predict with certainty fluctuations we may experience in our genetic test revenues or whether revenues derived from the Preferred Participation Agreement with RHSC, from our arrangements with Alticor-affiliated entities or from our discussions with other potential partners and customers will ever be material, or if material, will be sustained in future periods.

Results of Operations

Three Months Ended June 30, 2015 and 2014

Total revenue was $376,000 for the three months ended June 30, 2015 compared to $529,000 for the three months ended June 30, 2014. The change in total revenue is largely attributable to a decrease in the number of kits returned for processing related to our sales through ABG’s promotional product bundle program.

During the three months ended June 30, 2015, 46% of our sales revenue came through our Merchant Network and Channel Partner Agreement with Amway Global compared to 39% during the three months ended June 30, 2014. During the same periods, 16% and 38%, respectively, of our revenue came from sales through ABG’s promotional product bundle program.

Cost of revenue for the three months ended June, 30 2015 was $332,000, or 88.2% of revenue, compared to $362,000, or 68.4% of revenue, for the three months ended June 30, 2014. The increase in the cost of revenue as a percentage of revenue in the three months ended June 30, 2015 is primarily attributable to the fixed laboratory costs being applied to a lower volume of genetic tests being processed in the period.

Research and development expenses were $385,000 for the three months ended June 30, 2015, compared to $216,000 for the three months ended June 30, 2014. The increase of $169,000 or 78.4%, in research and development expenses is primarily attributable to increased compensation due to annual salary increases for existing staff, and to compensation and other expenses related to Dr. Kornman moving back into R&D from G&A in April 2015.

Selling, general and administrative expenses were $1.7 million for the three months ended June 30, 2015, compared to $1.5 million for the three months ended June 30, 2014. The increase of $200,000, or 13.3%, is primarily attributable to expenses related to recruiting our new Chief Executive Officer and higher patent related costs, partially offset by Dr. Kornman moving back into R&D.

Interest expense was $152,000 for the three months ended June 30, 2015, as compared to interest income of $1,600 for the three months ended June 30, 2014. The interest expense for the three months ended June 30, 2015 was related to our venture loan and security agreement with Horizon entered into on December 23, 2014.

Six Months Ended June 30, 2015 and 2014

Total revenue was $779,000 for the six months ended June 30, 2015 compared to $1.0 million for the six months ended June 30, 2014. The change in total revenue is largely attributable to a decrease in the number of kits returned for processing related to our sales through ABG’s promotional product bundle program.

During the six months ended June 30, 2015, 51% of our sales revenue came through our Merchant Network and Channel Partner Agreement with Amway Global compared to 37% during the six months ended June 30, 2014. During the same periods, 15% and 38%, respectively, of our revenue came from sales through ABG’s promotional product bundle program.

Cost of revenue for the six months ended June 30, 2015 was $663,000, or 85.0% of revenue, compared to $757,000, or 74.5% of revenue, for the six months ended June 30, 2014. The increase in the cost of revenue as a percentage of revenue in the six months ended June 30, 2015 is primarily attributable to the fixed laboratory costs being applied to a lower volume of genetic tests being processed in the period.

Research and development expenses were $567,000 for the six months ended June 30, 2015, compared to $425,000 for the six months ended June 30, 2014. The increase of $142,000 or 33.5%, in research and development expenses is primarily attributable to increased compensation due to annual salary increases for existing staff, and to compensation and other expenses related to Dr. Kornman being moved into R&D from G&A in April 2015.

Selling, general and administrative expenses were $3.2 million for the six months ended June 30, 2015, compared to $3.0 million for the six months ended June 30, 2014. The increase of $200,000, or 6.1%, is primarily attributable to increased compensation expenses based primarily on employee annual performance reviews, expenses related to recruiting our new Chief Executive Officer and higher patent related costs.

Interest expense was $303,000 for the six months ended June 30, 2015, as compared to interest income of 4,000 for the six months ended June 30, 2014. The interest expense for the six months ended June 30, 2015 was related to our venture loan and security agreement with Horizon entered into on December 23, 2014.

Liquidity and Capital Resources

As of June 30, 2015, we had cash and cash equivalents of $7.7 million.  

Cash used in operations was $3.8 million for the six months ended June 30, 2015 compared to $3.3 million for the six months ended June 30, 2014. Cash used in operations is primarily impacted by operating results and changes in working capital, particularly the timing of the collection of related party receivables, inventory levels, receipt of orders and the timing of payments to suppliers.

Cash used in investing activities was $22,000 for the six months ended June 30, 2015, compared to $61,000 for the six months ended June 30, 2014. The majority of the $22,000 in 2015 relates to the purchase of new IT equipment. The majority of the $61,000 in 2014 relates to the addition of new laboratory equipment and software.

Cash provided by financing activities was $4,000 for the six months ended June 30, 2015 compared to $19,000 for the six months ended June 30, 2014. The Company received $11,000 from stock purchases through the employee stock purchase plan during the six months ended June 30, 2015 compared to $19,000 for the six months ended June 30, 2014. The $11,000 received through the employee stock purchase plan for the six months ended June 30, 2015 was offset by $7,100 in additional fees related to the December 2014 Private Placement.

The amount of cash we generate from operations is currently not sufficient to continue to fund operations and grow our business. We expect that our current and anticipated financial resources will be adequate to maintain our current and planned operations for at least the next 12 months. If we are unable to obtain funding from our current or new investors, we may have to end our operations and seek protection under bankruptcy laws. We will need significant additional capital to fund our continued operations, to facilitate the continued commercial launch of our PerioPredict^® genetic test, for continued research and development efforts, for obtaining and protecting patents and for administrative expenses. We believe our success depends on our ability to have sufficient capital and liquidity to fund operations at least until we begin to receive significant revenues from the processing of the PerioPredict^® genetic test. The timing of any revenues that we may receive under the Preferred Participation Agreement with RHSC or any other agreements we may enter into with other partners is dependent upon the market adoption of the PerioPredict^® test, which timing is uncertain. We do not expect to receive any significant revenues for the PerioPredict^® test until 2016, at the earliest, and the timing of any such revenues may be substantially later. We may never receive significant revenues for the PerioPredict^® test or any of our other genetic tests.

Until such time, if ever, that we generate revenues sufficient to fund operations, we may fund our operations by issuing common stock, debt or other securities in one or more public or private offerings, as market conditions permit, or through the incurrence of debt from commercial lenders, but additional funding may not be available on favorable terms, or at all. We currently trade on the OTCQB^®. As a result, our access to capital through the public markets may be more limited. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our existing stockholders will be diluted, and the terms may include liquidation or other preferences that adversely affect the rights of our stockholders. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring debt, making capital expenditures or declaring dividends. There can be no assurance that additional funds will be available when we need them on terms that are acceptable to us, or at all. If adequate funds are not available to us on a timely basis, we may be required to delay, limit, reduce or cease activities or operations or enter into licenses or other arrangements with third parties on terms that may be unfavorable to us or sell, license or relinquish rights to develop or commercialize our products, technologies or intellectual property, or seek protection under U.S. bankruptcy laws. However, no assurance can be given at this time as to whether we will be able to achieve these objectives. The financial statements do not include any adjustment relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary should we be unable to continue as a going concern.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based upon our financial statements. The preparation of these financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires us to (i) make judgments, assumptions and estimates that affect the reported amounts of assets, liabilities, revenue and expenses; and (ii) disclose contingent assets and liabilities. A critical accounting estimate is an assumption that could have a material effect on our financial statements if another, also reasonable, amount were used or a change in the estimates is reasonably likely from period to period. We base our accounting estimates on historical experience and other factors that we consider reasonable under the circumstances. However, actual results may differ from these estimates. To the extent there are material differences between our estimates and the actual results, our future financial condition and results of operations will be affected. Our most critical accounting policies and estimates upon which our financial condition depends, and which involve the most complex or subjective decisions or assessments are set forth in Note 3 to our financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2014. There have been no significant changes in our accounting policies or changes from the methodology applied by management for critical accounting estimates previously disclosed in our most recent Annual Report on Form 10-K.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

As a smaller reporting company, we have elected scaled disclosure reporting obligations and therefore are not required to provide the information required by this Item 3.

Item 4. Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures. Our principal executive officer and principal financial officer, after evaluating the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15(d)-15(e)) as of the end of the period covered by this Quarterly Report on Form 10-Q, have concluded that, based on such evaluation, our disclosure controls and procedures were adequate and effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and is accumulated and communicated to our management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

(b) Changes in Internal Control Over Financial Reporting. No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15(d)-15(f)) occurred during the quarter ended June 30, 2015 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

There have been no material changes to the risk factors included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q and, in particular, our Management’s Discussion and Analysis of Financial Condition and Results of Operations set forth in Part I – Item 2, contains or incorporates a number of forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Exchange Act. Any or all of our forward-looking statements in this Quarterly Report on Form 10-Q may turn out to be wrong. They can be affected by inaccurate assumptions we might make or by known or unknown risks and uncertainties. Many factors mentioned in our discussion in this Quarterly Report on Form 10-Q will be important in determining future results. Consequently, no forward-looking statement can be guaranteed. Actual future results may vary materially.

25

Without limiting the foregoing, the words “believes,” “anticipates,” “plans,” “expects” and similar expressions are intended to identify forward-looking statements. There are a number of factors that could cause actual events or results to differ materially from those indicated by such forward-looking statements, many of which are beyond our control, including the factors set forth under “Item 1A. Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2014.. In addition, the forward-looking statements contained herein represent our estimates and expectations only as of the date of this filing and should not be relied upon as representing our estimates and expectations as of any subsequent date. While we may elect to update these forward-looking statements at some point in the future, we specifically disclaim any obligation to do so to reflect actual results, changes in assumptions or changes in other factors affecting such forward-looking statements.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

On April 6, 2015, we issued options to purchase an aggregate of up to 14,245,227 shares of common stock to Mark B. Carbeau, our Chief Executive Officer, as a new hire inducement grant. Options to purchase 2,622,948 shares were granted under our 2013 Employee, Director and Consultant Equity Incentive Plan (the “2013 Plan”), and options to purchase 11,622,279 shares were granted outside of the 2013 Plan pursuant to Section 4(a)(2) of the Securities Act.

Significant Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Note 3—Summary of Significant Accounting Policies

Management Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenue and expenses during the reported periods. Actual results could differ from those estimates. The Company’s most critical accounting policies are more fully discussed in these notes to the financial statements.

Revenue Recognition

Revenue from genetic testing services is recognized when there is persuasive evidence of an arrangement, service has been rendered, the sales price is determinable and collectability is reasonably assured. Service is deemed to be rendered when the results have been reported to the individual who ordered the test. To the extent that tests have been prepaid but results have not yet been reported, recognition of all related revenue is deferred. As of June 30, 2015 and December 31, 2014, the Company had deferred genetic test revenue of $3.0 million and $3.2 million, respectively. Included in deferred revenue at June 30, 2015 is $2.9 million for test kits that are still outstanding one year or longer after initial kit sale, of which $0.5 million was sold directly to consumers (credit card payments) and $2.4 million was sold to distributors for the Body Key promotional bundle.

The Company recognizes breakage revenue related to genetic test kits utilizing the remote method. Under the remote method, breakage revenue should be recognized when the likelihood of the customer exercising rights of redemption becomes remote. The term remote requires statistical analysis of customer redemption patterns for all tests sold and returned. The Company analyzed redemption patterns from 2009 through 2014 and determined the period of time after which the likelihood of test redemption was remote was three years after the sale of a genetic test kit. Included in genetic test revenue in the three and six months ended June 30, 2015 is $52,305 and $128,205, respectively, of breakage revenue related to unredeemed genetic test kits sold in the first and second quarters of 2012, compared to breakage revenue included in genetic test revenue in the three and six months ended June 30, 2014 of $92,364 and $156,861, respectively, related to unredeemed genetic test kits sold in the first and second quarters of 2011. The Company expects to continue to recognize breakage revenue on a quarterly basis based on the historical analysis.

Sales Commission

On October 26, 2009, the Company entered into a Merchant Network and Channel Partner Agreement with Amway Corp., d/b/a/ Amway Global (“Amway Global”), a subsidiary of Alticor Inc. (“Alticor”). Pursuant to this Agreement, Amway Global sells the Company’s Inherent Health® brand of genetic tests through its e-commerce website via a hyperlink to our e-commerce site. The Company accounts for sales commissions due to Amway Global under the Merchant Network and Channel Partner Agreement in accordance with SEC Staff Accounting Bulletin (“SAB”) 104. Commissions are recorded as an expense at the time they become due which is at the point of sale. The cost of commissions was $80,000 and $59,000 for the three months ended June 30, 2015 and 2014, respectively, and $168,000 and $101,000 for the six months ended June 30, 2015 and 2014, respectively.

Accounts Receivable

Accounts receivable is stated at estimated net realizable value, which is generally the invoiced amount less any estimated discount related to payment terms. The Company offers its commercial genetic test customers a 2% cash discount if payment is made by bank wire transfer within 10 days of the invoice date. No accounts receivable reserve is required at June 30, 2015 as all accounts receivable are expected to be collected.

Inventory

Inventory is carried at lower of cost (first-in, first-out method) or market and no inventory reserve is deemed necessary at June 30, 2015. As the Company does not manufacture any products, no overhead costs are included in inventory. The Company has contracted with a fulfillment provider to supply its PerioPredict^® genetic tests kits to dental offices. The agreement with the provider provides that the vendor will purchase and fulfill all materials related to the PerioPredict^® test and Body Key™  genetic test kits, with the Company’s approval. The Company pays for materials and fulfillment charges when the product is shipped. During the six months ended June 30, 2015, the Company purchased $33,000 of inventory related to its PerioPredict^® test, which is held at our fulfillment center. When a kit is sold, the corresponding cost of the kit is recorded as deferred cost of goods sold and removed from inventory. Any kit components remaining at the fulfillment center are reflected in inventory with a corresponding offset to accounts payable. At December 31, 2014 $48,000 of raw materials were at the fulfillment center and reflected in inventory with a corresponding entry to accounts payable.

Inventory consisted of the following:

	June 30, 2015		December 31, 2014
Raw materials	$	150,123	$	163,239
Finished goods		8,925		8,336
Total inventory, net	$	159,048	$	171,575

Stock-Based Compensation

The Company accounts for stock-based compensation expense in accordance with FASB ASC 718, Compensation – Stock Compensation. The standard addresses all forms of share-based payment (SBP) awards, including shares issued under employee stock purchase plans, stock options, restricted stock and stock appreciation rights. We expense SBP awards within compensation cost for SBP transactions measured at fair value. Compensation cost for the portion of awards for which the requisite service has not been rendered that are outstanding as of the effective date shall be recognized as the requisite service is rendered on or after the effective date. The compensation cost for that portion of awards shall be based on the grant-date fair value of those awards as calculated under the Black-Scholes option pricing model. Common stock purchased pursuant to our employee stock purchase plan will be expensed based upon the fair market value in excess of purchase price.

Income Taxes

The Company accounts for income taxes in accordance with FASB ASC 740, Income Taxes, which requires the recognition of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in the financial statements or tax returns. The measurement of current and deferred tax liabilities and assets is based on provisions of the enacted tax law; the effects of future changes in tax laws or rates are not anticipated. The Company records a valuation allowance to reduce its deferred tax assets to the amount that is more likely than not to be realized.

Significant management judgment is required in determining the Company’s provision (benefit) for income taxes, its deferred tax assets and liabilities and any valuation allowance recorded against deferred tax assets. The Company has recorded a full valuation allowance against its deferred tax assets of approximately $33.4 million as of June 30, 2015, due to uncertainties related to its ability to utilize these assets. The valuation allowance is based on management’s estimates of taxable income by jurisdiction in which the Company operates and the period over which the deferred tax assets will be recoverable. In the event that actual results differ from these estimates or management adjusts these estimates in future periods, the Company may need to adjust its valuation allowance, which could materially impact its financial position and results of operations.

As a result of the Company’s change in its capital structure during the quarters ending June 30, 2013 and December 23, 2014, the Company may have undergone an IRC section 382 ownership change which would limit its ability to realize the benefit of its tax attributes (i.e., federal/state net operating losses and research and development credits) during their respective carry forward periods. Furthermore, pursuant to the change in capital structure, the Company realized cancellation of indebtedness income under IRC section 108(e)(8), which reduced the Company’s federal net operating loss carry-forward pursuant to IRC section 108(b)(2)(A), due to the fact that the Company’s liabilities exceeded the fair market value of its assets. Accordingly, the Company had a reduction in its deferred tax asset and a corresponding reduction in its valuation allowance for the quarter ending June 30, 2013. The cancellation of indebtedness income resulted from a shareholder’s conversion of debt of approximately $14.3 million into common stock of the Company prior to an additional investment by an unrelated investor.

The Company reviews its recognition threshold and measurement process for recording in the financial statements uncertain tax positions taken or expected to be taken in a tax return. The Company reviews all material tax positions for all years open to statute to determine whether it is more likely than not that the positions taken would be sustained based on the technical merits of those positions. The Company did not recognize any adjustments for uncertain tax positions as of and during the six months ended June 30, 2015.

Research and Development

Research and development costs are expensed as incurred.

Basic and Diluted Net Loss per Common Share

The Company applies the provisions of FASB ASC 260, Earnings per Share, which establishes standards for computing and presenting earnings per share. Basic and diluted net loss per share was determined by dividing net loss applicable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted net loss per share is the same as basic net loss per share for all the periods presented, as the effect of the potential common stock equivalents is anti-dilutive due to the loss in each period. Potential common stock equivalents excluded from the calculation of diluted net loss per share are as follows:

	As of June 30,
	2015		2014
Options outstanding		22,288,867		5,989,800
Warrants outstanding		88,301,079		37,269,125
Total		110,589,946		43,258,925

Fair Value of Financial Instruments

The Company, using available market information, has determined the estimated fair values of financial instruments. The stated values of cash and cash equivalents, accounts receivable and accounts payable approximate fair value due to the short-term nature of these instruments. The fair value of warrants is calculated using the Black-Scholes pricing model.

Cash and Cash Equivalents

The Company maintains its cash and cash equivalents with domestic financial institutions that the Company believes to be of high credit standing. The Company believes that, as of June 30, 2015, its concentration of credit risk related to cash and cash equivalents was not significant. Cash and cash equivalents are available on demand and are generally in excess of FDIC insurance limits.

Fixed Assets

Fixed assets are stated at cost, less accumulated depreciation and amortization. Depreciation and amortization are provided using the straight-line method over estimated useful lives of three to five years. Leasehold improvements are amortized over the shorter of the estimated useful life of the asset or the remaining term of the lease.

Assets that have not yet been placed in service, have the costs incurred presented as part of Projects in Progress. Once the asset has been placed in service, the related costs are transferred to the appropriate category and depreciation commences. For the six months ended June 30, 2015 there is no balance in the Projects in Progress account.

Segment Reporting

As of June 30, 2015 and 2014, the Company has one segment, the genetic test business. The Company develops genetic tests for sale into the emerging personalized health market and performs testing services that can help individuals improve and maintain their health through preventive measures. The Company’s principal operations and markets are located in the United States.

Recent Accounting Pronouncements

FASB ASU 2015-03 - Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.

In April 2015, the FASB issued ASU No. 2015-03, which requires that debt issuance costs be reported in the balance sheet as a direct deduction from the face amount of the related liability, consistent with the presentation of debt discounts.  Prior to the amendments, debt issuance costs were presented as a deferred charge (i.e., an asset) on the balance sheet.  Further, the amendments require the amortization of debt issuance costs to be reported as interest expense. Similarly, debt issuance costs and any discount or premium are considered in the aggregate when determining the effective interest rate on the debt. The amendments are effective for public business entities for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The amendments must be applied retrospectively.  All entities have the option of adopting the new requirements as of an earlier date for financial statements that have not been previously issued. The Company does not expect this ASU to have a material impact on its consolidated financial statements.

FASB ASC 606 ASU 2014-09 - Revenue from contracts with customers.

In May 2014, the FASB issued amended guidance on contracts with customers to transfer goods or services or contracts for the transfer of nonfinancial assets, unless those contracts are within the scope of other standards (e.g., insurance contracts or lease contracts). The guidance requires an entity to recognize revenue on contracts with customers 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. The guidance requires that an entity depict the consideration by applying the following five steps:

· Identify the contract(s) with a customer.

· Identify the performance obligations in the contract.

· Determine the transaction price.

· Allocate the transaction price to the performance obligations in the contract.

· Recognize revenue when (or as) the entity satisfies a performance obligation.

The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. This amendment is to be either retrospectively adopted to each prior reporting period presented or retrospectively with the cumulative effect of initially applying this ASU recognized at the date of initial application.

In April, 2015 the FASB voted to defer the required implementation date of ASU 2014-09 to December 2017. Public companies may elect to adopt the standard along the original timeline. We are evaluating the impact of the adoption of this guidance to determine whether or not it has a material impact on the Company's financial statements.

FASB ASC 606 ASU 2014-15 - Presentation of Financial Statements—Going Concern (Subtopic 205-40); Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.

In August 2014, the FASB issued ASU No. 2014-15, which applies should a company be facing probable liquidation within one year of the issuance of the financial statements, but is not actually in liquidation at the time of issuance.  The applicable basis for presentation remains as a going concern, but if liquidation within one year is probable, then certain disclosures must be included in the financial statement presentation.  ASU 2014-15 is effective for annual and interim periods beginning after December 15, 2016, with early adoption permitted. We are evaluating the impact of ASU 2014-15 on our financial disclosures, but are not electing early adoption at this time.

Going Concern [Abstract]

Operating Matters and Liquidity

Note 2—Operating Matters and Liquidity

The Company has experienced net operating losses since its inception through June 30, 2015. The Company had net losses of $6.3 million and $7.1 million for the years ended December 31, 2014 and 2013, respectively, and $4.0 million for the six months ended June 30, 2015, contributing to an accumulated deficit of $125.1 million as of June 30, 2015.

The Company continues to take steps to reduce genetic test processing costs. Cost savings are primarily achieved through test process improvements. Management believes that the current laboratory space is adequate to process high volumes of genetic tests.

On May 17, 2013, the Company entered into a Common Stock Purchase Agreement (the “2013 Purchase Agreement”) with various accredited investors (the “2013 Investors”), pursuant to which the Company sold securities to the 2013 Investors in a private placement transaction (the “May 2013 Private Placement”). In the May 2013 Private Placement, the Company sold an aggregate of 43,715,847 shares of common stock at a price of $0.2745 per share for gross proceeds of $12,000,000. The 2013 Investors also received warrants to purchase up to an aggregate of 32,786,885 shares of common stock an exercise price of $0.2745 per share (the “2013 Warrants”). The 2013 Warrants are all currently exercisable and have a term of seven years from the date they became exercisable.

On December 23, 2014, the Company entered into a Securities Purchase Agreement (the “2014 Purchase Agreement”) with various accredited investors (the “2014 Investors”), pursuant to which the Company sold to the 2014 Investors in a private placement transaction (the “December 2014 Private Placement”) an aggregate of 50,099,700 shares of common stock at a price of $0.1003 per share for gross proceeds of approximately $5.025 million. The 2014 Investors also received warrants to purchase up to an aggregate of 50,099,700 shares of common stock an exercise price of $0.1003 per share (the “2014 Warrants”). The 2014 Warrants are all currently exercisable and have a term of seven years.

On December 23, 2014, the Company entered into a Venture Loan and Security Agreement (the “Loan Agreement”) with Horizon Technology Finance Corporation (the “Lender”) under which the Company has borrowed $5.0 million. The loan bears interest at a floating rate equal to the One Month LIBOR Rate (with a floor of 0.50%) plus 8.50%. In the event that the One Month LIBOR Rate, as reported in the Wall Street Journal, exceeds 0.50%, the interest rate will be adjusted by an amount equal to the difference between such rates at the end of that particular month. At June 30, 2015, the rate was 9.0% per annum. The loan is to be repaid in forty-five (45) monthly payments consisting of fifteen (15) monthly payments of only interest followed by thirty (30) equal monthly payments of principal and interest. In addition, at the end of the repayment term (or at early termination of the loan) a final payment equal to 4.5% of the loan will be due and payable. The Company’s obligations under the Loan Agreement are secured by a first priority security interest in substantially all of its assets other than its intellectual property. The Company has also agreed not to pledge or otherwise encumber its intellectual property assets, subject to certain exceptions. In connection with the Loan Agreement, the Company issued to the Lender and its affiliates warrants to purchase a total of 2,492,523 shares of common stock at an exercise price of $0.1003 per share, which the Company refers to herein as the Lender Warrants. The Lender Warrants have a term of ten (10) years.

   The Company’s financial statements have been prepared assuming that it will continue as a going concern which contemplates the realization of assets and satisfaction of liabilities in the normal course of business.  The financial statements do not include any adjustments that might result from the outcome of this uncertain realization. The Company expects to incur additional losses in 2015 and, accordingly, is dependent on financings and potential revenue to fund its operations  and support the market adoption of the PerioPredict^®  test. The timing of any revenues that the Company may receive from the PerioPredict^®  test is uncertain at this time, and is contingent upon a number of factors, including the Company’s ability to consummate arrangements with partners to promote the PerioPredict^®  test, the Company and its partners’ ability to develop insurance plans that provide for use and reimbursement of the PerioPredict^® test, or other possible arrangements, and to develop a viable market for such plans, and the timing of utilization of the PerioPredict^® test pursuant to such plans. The Company expects to have the cash resources necessary to fund its operations for at least the next twelve months.

The ability of the Company to realize the carrying value of its fixed assets and intangible assets is dependent on management’s ability to successfully execute on its plan. The Company needs to generate additional funds in order to meet its financial obligations. If it is unsuccessful in doing so, the Company may not be able to realize the carrying value of its fixed assets and intangible assets.

Significant Accounting Policies [Abstract]

Management Estimates

Management Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenue and expenses during the reported periods. Actual results could differ from those estimates. The Company’s most critical accounting policies are more fully discussed in these notes to the financial statements.

Revenue Recognition

Revenue Recognition

Revenue from genetic testing services is recognized when there is persuasive evidence of an arrangement, service has been rendered, the sales price is determinable and collectability is reasonably assured. Service is deemed to be rendered when the results have been reported to the individual who ordered the test. To the extent that tests have been prepaid but results have not yet been reported, recognition of all related revenue is deferred. As of June 30, 2015 and December 31, 2014, the Company had deferred genetic test revenue of $3.0 million and $3.2 million, respectively. Included in deferred revenue at June 30, 2015 is $2.9 million for test kits that are still outstanding one year or longer after initial kit sale, of which $0.5 million was sold directly to consumers (credit card payments) and $2.4 million was sold to distributors for the Body Key promotional bundle.

The Company recognizes breakage revenue related to genetic test kits utilizing the remote method. Under the remote method, breakage revenue should be recognized when the likelihood of the customer exercising rights of redemption becomes remote. The term remote requires statistical analysis of customer redemption patterns for all tests sold and returned. The Company analyzed redemption patterns from 2009 through 2014 and determined the period of time after which the likelihood of test redemption was remote was three years after the sale of a genetic test kit. Included in genetic test revenue in the three and six months ended June 30, 2015 is $52,305 and $128,205, respectively, of breakage revenue related to unredeemed genetic test kits sold in the first and second quarters of 2012, compared to breakage revenue included in genetic test revenue in the three and six months ended June 30, 2014 of $92,364 and $156,861, respectively, related to unredeemed genetic test kits sold in the first and second quarters of 2011. The Company expects to continue to recognize breakage revenue on a quarterly basis based on the historical analysis.

Sales Commissions

Sales Commission

On October 26, 2009, the Company entered into a Merchant Network and Channel Partner Agreement with Amway Corp., d/b/a/ Amway Global (“Amway Global”), a subsidiary of Alticor Inc. (“Alticor”). Pursuant to this Agreement, Amway Global sells the Company’s Inherent Health® brand of genetic tests through its e-commerce website via a hyperlink to our e-commerce site. The Company accounts for sales commissions due to Amway Global under the Merchant Network and Channel Partner Agreement in accordance with SEC Staff Accounting Bulletin (“SAB”) 104. Commissions are recorded as an expense at the time they become due which is at the point of sale. The cost of commissions was $80,000 and $59,000 for the three months ended June 30, 2015 and 2014, respectively, and $168,000 and $101,000 for the six months ended June 30, 2015 and 2014, respectively.

Accounts Receivable

Accounts Receivable

Accounts receivable is stated at estimated net realizable value, which is generally the invoiced amount less any estimated discount related to payment terms. The Company offers its commercial genetic test customers a 2% cash discount if payment is made by bank wire transfer within 10 days of the invoice date. No accounts receivable reserve is required at June 30, 2015 as all accounts receivable are expected to be collected.

Inventory

Inventory

Inventory is carried at lower of cost (first-in, first-out method) or market and no inventory reserve is deemed necessary at June 30, 2015. As the Company does not manufacture any products, no overhead costs are included in inventory. The Company has contracted with a fulfillment provider to supply its PerioPredict^® genetic tests kits to dental offices. The agreement with the provider provides that the vendor will purchase and fulfill all materials related to the PerioPredict^® test and Body Key™  genetic test kits, with the Company’s approval. The Company pays for materials and fulfillment charges when the product is shipped. During the six months ended June 30, 2015, the Company purchased $33,000 of inventory related to its PerioPredict^® test, which is held at our fulfillment center. When a kit is sold, the corresponding cost of the kit is recorded as deferred cost of goods sold and removed from inventory. Any kit components remaining at the fulfillment center are reflected in inventory with a corresponding offset to accounts payable. At December 31, 2014 $48,000 of raw materials were at the fulfillment center and reflected in inventory with a corresponding entry to accounts payable.

Inventory consisted of the following:

	June 30, 2015		December 31, 2014
Raw materials	$	150,123	$	163,239
Finished goods		8,925		8,336
Total inventory, net	$	159,048	$	171,575

Stock-Based Compensation

Stock-Based Compensation

The Company accounts for stock-based compensation expense in accordance with FASB ASC 718, Compensation – Stock Compensation. The standard addresses all forms of share-based payment (SBP) awards, including shares issued under employee stock purchase plans, stock options, restricted stock and stock appreciation rights. We expense SBP awards within compensation cost for SBP transactions measured at fair value. Compensation cost for the portion of awards for which the requisite service has not been rendered that are outstanding as of the effective date shall be recognized as the requisite service is rendered on or after the effective date. The compensation cost for that portion of awards shall be based on the grant-date fair value of those awards as calculated under the Black-Scholes option pricing model. Common stock purchased pursuant to our employee stock purchase plan will be expensed based upon the fair market value in excess of purchase price.

Income Taxes

Income Taxes

The Company accounts for income taxes in accordance with FASB ASC 740, Income Taxes, which requires the recognition of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in the financial statements or tax returns. The measurement of current and deferred tax liabilities and assets is based on provisions of the enacted tax law; the effects of future changes in tax laws or rates are not anticipated. The Company records a valuation allowance to reduce its deferred tax assets to the amount that is more likely than not to be realized.

Significant management judgment is required in determining the Company’s provision (benefit) for income taxes, its deferred tax assets and liabilities and any valuation allowance recorded against deferred tax assets. The Company has recorded a full valuation allowance against its deferred tax assets of approximately $33.4 million as of June 30, 2015, due to uncertainties related to its ability to utilize these assets. The valuation allowance is based on management’s estimates of taxable income by jurisdiction in which the Company operates and the period over which the deferred tax assets will be recoverable. In the event that actual results differ from these estimates or management adjusts these estimates in future periods, the Company may need to adjust its valuation allowance, which could materially impact its financial position and results of operations.

As a result of the Company’s change in its capital structure during the quarters ending June 30, 2013 and December 23, 2014, the Company may have undergone an IRC section 382 ownership change which would limit its ability to realize the benefit of its tax attributes (i.e., federal/state net operating losses and research and development credits) during their respective carry forward periods. Furthermore, pursuant to the change in capital structure, the Company realized cancellation of indebtedness income under IRC section 108(e)(8), which reduced the Company’s federal net operating loss carry-forward pursuant to IRC section 108(b)(2)(A), due to the fact that the Company’s liabilities exceeded the fair market value of its assets. Accordingly, the Company had a reduction in its deferred tax asset and a corresponding reduction in its valuation allowance for the quarter ending June 30, 2013. The cancellation of indebtedness income resulted from a shareholder’s conversion of debt of approximately $14.3 million into common stock of the Company prior to an additional investment by an unrelated investor.

The Company reviews its recognition threshold and measurement process for recording in the financial statements uncertain tax positions taken or expected to be taken in a tax return. The Company reviews all material tax positions for all years open to statute to determine whether it is more likely than not that the positions taken would be sustained based on the technical merits of those positions. The Company did not recognize any adjustments for uncertain tax positions as of and during the six months ended June 30, 2015.

Research and Development

Research and Development

Research and development costs are expensed as incurred.

Basic and Diluted Net Loss per Common Share

Basic and Diluted Net Loss per Common Share

The Company applies the provisions of FASB ASC 260, Earnings per Share, which establishes standards for computing and presenting earnings per share. Basic and diluted net loss per share was determined by dividing net loss applicable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted net loss per share is the same as basic net loss per share for all the periods presented, as the effect of the potential common stock equivalents is anti-dilutive due to the loss in each period. Potential common stock equivalents excluded from the calculation of diluted net loss per share are as follows:

	As of June 30,
	2015		2014
Options outstanding		22,288,867		5,989,800
Warrants outstanding		88,301,079		37,269,125
Total		110,589,946		43,258,925

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The Company, using available market information, has determined the estimated fair values of financial instruments. The stated values of cash and cash equivalents, accounts receivable and accounts payable approximate fair value due to the short-term nature of these instruments. The fair value of warrants is calculated using the Black-Scholes pricing model.

Cash and Cash Equivalents

Cash and Cash Equivalents

The Company maintains its cash and cash equivalents with domestic financial institutions that the Company believes to be of high credit standing. The Company believes that, as of June 30, 2015, its concentration of credit risk related to cash and cash equivalents was not significant. Cash and cash equivalents are available on demand and are generally in excess of FDIC insurance limits.

Fixed Assets

Fixed Assets

Fixed assets are stated at cost, less accumulated depreciation and amortization. Depreciation and amortization are provided using the straight-line method over estimated useful lives of three to five years. Leasehold improvements are amortized over the shorter of the estimated useful life of the asset or the remaining term of the lease.

Assets that have not yet been placed in service, have the costs incurred presented as part of Projects in Progress. Once the asset has been placed in service, the related costs are transferred to the appropriate category and depreciation commences. For the six months ended June 30, 2015 there is no balance in the Projects in Progress account.

Segment Reporting

Segment Reporting

As of June 30, 2015 and 2014, the Company has one segment, the genetic test business. The Company develops genetic tests for sale into the emerging personalized health market and performs testing services that can help individuals improve and maintain their health through preventive measures. The Company’s principal operations and markets are located in the United States.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

FASB ASU 2015-03 - Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs.

In April 2015, the FASB issued ASU No. 2015-03, which requires that debt issuance costs be reported in the balance sheet as a direct deduction from the face amount of the related liability, consistent with the presentation of debt discounts.  Prior to the amendments, debt issuance costs were presented as a deferred charge (i.e., an asset) on the balance sheet.  Further, the amendments require the amortization of debt issuance costs to be reported as interest expense. Similarly, debt issuance costs and any discount or premium are considered in the aggregate when determining the effective interest rate on the debt. The amendments are effective for public business entities for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The amendments must be applied retrospectively.  All entities have the option of adopting the new requirements as of an earlier date for financial statements that have not been previously issued. The Company does not expect this ASU to have a material impact on its consolidated financial statements.

FASB ASC 606 ASU 2014-09 - Revenue from contracts with customers.

In May 2014, the FASB issued amended guidance on contracts with customers to transfer goods or services or contracts for the transfer of nonfinancial assets, unless those contracts are within the scope of other standards (e.g., insurance contracts or lease contracts). The guidance requires an entity to recognize revenue on contracts with customers 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. The guidance requires that an entity depict the consideration by applying the following five steps:

· Identify the contract(s) with a customer.

· Identify the performance obligations in the contract.

· Determine the transaction price.

· Allocate the transaction price to the performance obligations in the contract.

· Recognize revenue when (or as) the entity satisfies a performance obligation.

The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. This amendment is to be either retrospectively adopted to each prior reporting period presented or retrospectively with the cumulative effect of initially applying this ASU recognized at the date of initial application.

In April, 2015 the FASB voted to defer the required implementation date of ASU 2014-09 to December 2017. Public companies may elect to adopt the standard along the original timeline. We are evaluating the impact of the adoption of this guidance to determine whether or not it has a material impact on the Company's financial statements.

FASB ASC 606 ASU 2014-15 - Presentation of Financial Statements—Going Concern (Subtopic 205-40); Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.

In August 2014, the FASB issued ASU No. 2014-15, which applies should a company be facing probable liquidation within one year of the issuance of the financial statements, but is not actually in liquidation at the time of issuance.  The applicable basis for presentation remains as a going concern, but if liquidation within one year is probable, then certain disclosures must be included in the financial statement presentation.  ASU 2014-15 is effective for annual and interim periods beginning after December 15, 2016, with early adoption permitted. We are evaluating the impact of ASU 2014-15 on our financial disclosures, but are not electing early adoption at this time.

Note 6—Commitments and contingencies

Operating Lease

The Company leases its office and laboratory space under a non-cancelable operating lease which was originally scheduled to expire on March 31, 2014. In May 2010, the Company completed a sublease of 6,011 square feet of underutilized office and laboratory space and on March 31, 2014, the sublease expired. On February 7, 2014, the Company entered into the Second Amendment to Commercial Lease which, among other things a) extended the term of the lease from March 31, 2014 to March 31, 2017; b) reduced the 19,000 square feet, the amount of space under the master lease, by approximately 6,011 square feet, to approximately 13,000 square feet, which is the amount of space the Company currently occupies; and, c) set an initial base rent with an escalation of 2.06% of base rent in year two and another 2.06% in year three.

Rent expense, net of the benefit of the sublease in 2014, was $94,000 and $79,000 for the three months ended June 30, 2015 and 2014, respectively, and $173,000 and $150,000 for the six months ended June 30, 2015 and 2014, respectively.

Industry Risk and Concentration

Note 9—Industry Risk and Concentration

The Company develops genetic risk assessment tests and performs research for its own benefit. As of June 30, 2015, the Company sells five genetic risk assessment tests. Commercial success of the Company’s genetic risk assessment tests will depend on their success as being deemed to be scientifically credible and cost-effective by consumers and the marketing success of the Company and its collaborative partners.

Research in the field of disease predisposing genes and genetic markers is intense and highly competitive. The Company has many competitors in the United States and abroad that have considerably greater financial, technical, marketing, and other resources available. If the Company does not discover disease predisposing genes or genetic markers and develop risk assessment tests and launch such services or products before its competitors, then the potential for significant revenues may be reduced or eliminated.

During the three months ended June 30, 2015 and 2014, approximately 46% and 39%, respectively, of the Company’s revenue came from sales through the Merchant Network and Channel Partner Agreement with Amway Global, and 16% and 38%, respectively, of the Company’s revenue came from sales through ABG’s promotional product bundle program. During the six months ended June 30, 2015 and 2014, approximately 51% and 37%, respectively, of the Company’s revenue came from sales through the Merchant Network and Channel Partner Agreement with Amway Global, and 15% and 38%, respectively, of the Company’s revenue came from sales through ABG’s promotional product bundle program.

Note 4—Related Party Transactions

Since March 2003, the Company has maintained a broad strategic alliance with several affiliates of the Alticor Inc. family of companies, a related party. The alliance initially included an equity investment, a multi-year research and development agreement, a licensing agreement with royalties on marketed products, the deferment of outstanding loan repayment and the refinancing of bridge financing obligations.

On October 26, 2009, the Company entered into a Merchant Network and Channel Partner Agreement with Amway Corp., d/b/a/ Amway Global (“Amway Global”), a subsidiary of Alticor Inc. Pursuant to this Agreement, Amway Global sells the Company’s Inherent Health^® brand of genetic tests through its e-commerce website via a hyperlink to the Company’s e-commerce site. The Company paid Amway Global $80,000 and $59,000 in commissions for the three months ended June 30, 2015 and 2014, respectively, and $168,000 and $101,000 in commissions for the six months ended June 30, 2015 and 2014, respectively, representing a percentage of net sales to their customers. The Company expenses commissions owed to Amway Global in the month of sale to the customer.

Beginning in September 2012 and again in 2013, Access Business Group LLC (“ABG”), an affiliate of Alticor, placed purchase orders totaling approximately $3.3 million consisting of Weight Management test kits. The kits are included as part of a promotional bundle of products that Amway is now selling to their Individual Business Owners (IBOs). Of the $3.3 million in orders, $1.5 million was received for the 2013 program and $1.8 million for the 2014 program. As a component of the 2013 promotional program, and not reflective of actual product expiry, the kits were required to be redeemed by December 31, 2013. In February 2014, the Company removed the redemption date requirement for the 2013 promotional program, for which ABG paid the Company $519,000 as a retrospective increase in the product purchase price. All cash received related to the 2013 promotional program, including the $519,000, will be treated as deferred revenue until specific kits are returned for processing or the breakage analysis determines the probability of eventual redemption is remote. In October 2014, the Company received $250,000 as a retrospective increase in the product purchase price for unsold kits as consideration for extending the required redemption date of the 2014 promotional program to December 31, 2017. All cash received for these kits will be treated as deferred revenue until specific kits are returned for processing or on the final allowed redemption date of December 31, 2017.

On September 21, 2012, the Company entered into a License Agreement with Access Business Group International LLC (“ABGI”), an affiliate of Alticor. Pursuant to the License Agreement, the Company has granted ABGI and its affiliates a non-exclusive license to use the technology related to Interleukin’s Weight Management genetic test and to sell the Weight Management test in Europe, Russia and South Africa (the “Territories”). ABGI, or a laboratory designated by ABGI, will be responsible for processing the tests, and the Company will receive a royalty for each test sold, which royalty will increase if certain pending patent applications are issued. The License Agreement has an initial term of five years from the date of first commercial sale of the Weight Management test under the agreement which was June 2013. Thereafter, the term will automatically renew for additional one-year periods unless notice is delivered by either party at least 60 days prior to the anniversary date. During the three and six months ended June 30, 2015, $49,000 and $103,203, respectively, was earned, compared to $43,000 and $97,885 in the same periods in 2014

In connection with the execution of the License Agreement, the Company and ABGI also entered into a Professional Services Agreement (the “PSA”) pursuant to which the Company has agreed to provide services to ABGI in connection with its sale and processing of the tests within the Territories. No fees were earned in the year ended December 31, 2014 or the six months ended June 30, 2015 under the PSA.

For the three months ended June 30, 2015 and 2014, approximately 46% and 39%, respectively, of the Company’s revenue came from sales through the Merchant Network and Channel Partner Agreement with Amway Global, and 16% and 38%, respectively, of the Company’s revenue came from sales through ABG’s promotional product bundle program. For the six months ended June 30, 2015 and 2014, approximately 51% and 37%, respectively, of the Company’s revenue came from sales through the Merchant Network and Channel Partner Agreement with Amway Global, and 15% and 38%, respectively, of the Company’s revenue came from sales through ABG’s promotional product bundle program.

On February 25, 2013, the Company entered into a Preferred Participation Agreement with Renaissance Health Services Corporation (“RHSC”), for itself and on behalf of certain of its affiliates and subsidiaries. RHSC is a related party through its affiliation with Delta Dental of Michigan, Inc. (“DDMI”), a stockholder of the Company.  Pursuant to this agreement, affiliates of RHSC agreed to reimburse the Company a fixed price for each PerioPredict^® genetic test that the Company processed for a customer of affiliates of RHSC. In addition, if during the term of the agreement the Company offered the PerioPredict^® test to any other person or party for a lower price, such lower price would then be applicable to tests processed for a customer of affiliates of RHSC for the remainder of the term of the agreement. The pricing arrangement was subject to the satisfaction of certain milestones, including that (1) within a specified timeframe, RHSC affiliates were to develop and offer dental benefit plans for which a significant portion of such affiliate's clients are eligible that provided for use of the PerioPredict^® test and reimbursement of the test at the agreed upon price (each such plan, hereinafter referred to as a “Reimbursed Dental Plan”) and (2) prior to a specified date, RHSC affiliates were to have sold policies for Reimbursed Dental Plans for the year beginning January 1, 2014. The Company agreed that for a one year period beginning on the date on which RHSC affiliates first offered a Reimbursed Dental Plan, it would make the PerioPredict^® test available solely to RHSC affiliates and not to any other third party or person. This agreement had a term of three years beginning on February 25, 2013.

On November 1, 2013, the Company entered into an Amended and Restated Preferred Participation Agreement with RHSC, for itself and on behalf of certain of its affiliates and subsidiaries.  Pursuant to this agreement, affiliates of RHSC have agreed to reimburse the Company a fixed price for each PerioPredict^® genetic test that the Company processes for a customer of affiliates of RHSC. In addition, if during the term of the agreement the Company offers the PerioPredict^® test to any other person or party for a lower price, such lower price shall then be applicable to tests processed for a customer of such affiliates of RHSC for the remainder of the term of the agreement. RHSC and its affiliates will continue to receive the preferred pricing (or any lower market price during the term) only for so long as affiliates of RHSC continue to: (a) work to develop and to offer Reimbursed Dental Plans for which a significant portion of employees of RHSC’s affiliates’ customers are eligible; and (b) exercise their commercially-reasonable best efforts to maximize the number of customers that offer a Reimbursed Dental Plan. In addition, under the terms of the amended agreement, the Company is no longer obligated to make the PerioPredict^® test available solely to RHSC affiliates and not to any other third party or person. This amended agreement has a term of three years beginning February 25, 2013, unless terminated earlier  (1) upon the mutual written agreement of us and RHSC, (2) if either party becomes the subject of bankruptcy, insolvency, liquidation or other similar proceedings, or (3) in the event of an uncured breach of the amended agreement by either party.

The timing of any revenues that the Company may receive under the amended agreement with RHSC is dependent upon the timing of the offering of Reimbursed Dental Plans and the subsequent adoption of such Reimbursed Dental Plans by RHSC customers, the timing of which is very uncertain at this time and is dependent on a viable market developing for such plans. RHSC has informed us that it has presented the scientific data underlying Reimbursed Dental Plans to a number of customers and will make available Reimbursed Dental Plans as an alternative to a customer’s current plan for any customer that expresses an interest in such a plan. The Company may never receive significant revenues under this agreement.
