Nature of Operations

NOTE 1:

NATURE OF OPERATIONS

TapImmune Inc. (the “Company”), a Nevada corporation incorporated in 1992, is a biotechnology Company focusing on immunotherapy specializing in the development of innovative peptide and gene-based immunotherapeutics and vaccines for the treatment of oncology and infectious disease. Unlike other vaccine technologies that narrowly address the initiation of an immune response, TapImmune’s approach broadly stimulates the cellular immune system by enhancing the function of killer T-cells and T-helper cells and by restoring antigen presentation in tumor cells allowing their recognition and killing by the immune system.

A Phase I study at the Mayo Clinic, Rochester, MN, evaluating the safety and immune responses of a set of proprietary HER2/neu+ antigens has been successfully completed and the results led to the decision to proceed with Phase II clinical studies in 2016.

A separate Phase I study has also been conducted at Mayo Foundation (“Mayo”) in Ovarian and breast cancer (Folate Receptor Alpha). Folate Receptor Alpha is expressed in nearly 50% of breast cancers and in addition, over 95% of ovarian cancers, for which the only treatment options are surgery and chemotherapy, leaving a very important and urgent clinical need for a new therapeutic. Time to recurrence is relatively short for this type of cancer and survival prognosis is extremely poor after recurrence. In the USA alone, there are approximately 30,000 ovarian cancer patients newly diagnosed every year. These Folate Receptor Antigens are applicable to Ovarian and Triple Negative Breast Cancer. Both of these diseases have few treatment options if any beyond surgery and chemotherapy and therefore the Company is hopeful that it might be an ideal candidate for orphan drug status in these indications. This study has been successfully completed and the results led to the decision to proceed with multiple Phase II studies in 2016.

In addition, enhancing the visibility of cancer or infected cells to a patient’s immune system is a critical aspect of an effective vaccine. In this regard, TapImmune’s PolyStart nucleic acid-based technology provides a four-fold increase in target cell specific naturally processed antigenic epitopes on a cells surface. This increased cell surface presentation corresponding increases activated Helper and/or long-lived Killer T-cell populations that then effectively seek out and work to destroy a patient’s cancer cells.

These consolidated financial statements have been prepared on the basis of a going concern which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. As at December 31, 2015, the Company had a working capital deficiency and has incurred significant losses since inception in the development of its business. The ability of the Company to continue as a going concern is dependent on raising additional capital to fund clinical trials, ongoing research and development, maintenance and protection of patents, accommodation from certain debt obligations and ultimately on generating future profitable operations. Planned expenditures relating to current and future clinical trials of the Company’s immunotherapy vaccine will require significant additional funding. The Company is dependent on future financings to fund ongoing research and development as well as working capital requirements. The Company’s future capital requirements will depend on many factors including the rate and extent of scientific progress in its research and development programs, the timing, cost and scope involved in clinical trials, obtaining regulatory approvals, pursuing further patent protections and the timing and costs of commercialization activities.

Management is addressing going concern remediation through seeking new sources of capital, restructuring and retiring debt through conversion to equity and debt settlement arrangements with creditors, cost reduction programs and seeking possible joint venture participation. Management’s plans are intended to return the Company to financial stability and improve continuing operations. The Company is continuing initiatives to raise capital through private placements, related party loans and other institutional sources to meet immediate working capital requirements.

Historically the Company has raised capital through issuances of various financial instruments and the Company recently completed significant restructuring of outstanding debt and equity instruments into equity. Additional capital is required to expand programs including pre-clinical work and to progress clinical trials for the lead vaccine candidates. Strategic partnerships will be needed to continue the product development portfolio and fund development costs. These measures, if successful, may contribute to reduce the risk of going concern uncertainties for the Company over the next twelve months.

There is no certainty that the Company will be able to arrange sufficient funding to satisfy current debt obligations or to continue development of products to marketability.

Summary of Significant Accounting Policies

NOTE 2:

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

These financial statements are presented in United States dollars and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”).

Principles of Consolidation

These financial statements include the accounts of the Company and its wholly-owned subsidiary GeneMax Pharmaceuticals Inc. (“GPI”). All significant intercompany balances and transactions are eliminated upon consolidation.

Use of Estimates

Preparation of the Company’s financial statements in conformity with GAAP requires management to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results could differ materially from those estimates. Significant areas requiring management’s estimates and assumptions include valuation allowance on deferred tax assets, determining the fair value of stock-based compensation and stock based transactions, the fair value of the components of the derivative liabilities - warrants and accrued liabilities.

Fair Value Measurements

The fair value of certain of the Company’s financial instruments, including cash and cash equivalents, accrued compensation, and other accrued liabilities, approximate cost because of their short maturities. The Company measures the fair value of certain of its financial assets and liabilities on a recurring basis. A fair value hierarchy is used to rank the quality and reliability of the information used to determine fair values. Financial assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories:

•

Level 1-Quoted prices (unadjusted) in active markets for identical assets and liabilities.

•

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

•

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

The fair values of cash, accounts payable, and other current monetary liabilities approximate their carrying values due to the immediate or short-term maturity of these financial instruments. The Company’s operations and financing activities are conducted primarily in United States dollars, and as a result the Company is not subject to significant exposure to market risks from changes in foreign currency rates. Unless otherwise noted, it is management’s opinion that the Company is not exposed to significant interest or credit risks arising from assets and liabilities classified as financial instruments.

Prior Period Reclassifications

Certain prior period amounts that were combined in the December 31, 2014 consolidated financial statements have been reclassified for comparability with the December 31, 2015 presentation. These reclassifications had no effect on previously reported net loss.

Stock-Based Compensation

Stock-based compensation is measured at the grant date based on the fair value of the award. The fair value of the award that is ultimately expected to vest is recognized as expense on a straight-line basis over the requisite service period, which is generally the vesting period. The expense recognized for the portion of the award that is expected to vest has been reduced by an estimated forfeiture rate. The forfeiture rate is determined at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

Expected Term — The expected term of options represents the period that the Company’s stock-based awards are expected to be outstanding based on the simplified method, which is the half-life from vesting to the end of its contractual term.

Expected Volatility — The Company computes stock price volatility over expected terms based on its historical common stock trading prices.

Risk-Free Interest Rate — The Company bases the risk-free interest rate on the implied yield available on U. S. Treasury zero-coupon issues with an equivalent remaining term.

Expected Dividend — The Company has never declared or paid any cash dividends on its common shares and does not plan to pay cash dividends in the foreseeable future, and, therefore, uses an expected dividend yield of zero in its valuation models. The Company recognizes fair value of stock options granted to nonemployees as stock-based compensation expense over the period in which the related services are received.

Research and Development Costs

The Company has acquired development and marketing rights to certain technologies. The rights and licenses acquired are considered rights to unproven technology which may not have alternate future uses and therefore, have been expensed as incurred as research and development costs. The Company spent $1,711,000 on research and development in the year ended December 31, 2015 compared to $189,000 during the prior fiscal year.

Income Taxes

The Company follows the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax balances. Potential deferred tax assets and liabilities are measured using enacted tax rates expected to apply to the taxable income in the years in which those differences are expected to be recovered or settled. The effect on potential deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the date of allowances against deferred tax assets.

Derivative Liability

The Company evaluates its convertible debt, options, warrants or other contracts to determine if those contracts or embedded components of those contracts qualify as derivatives to be separately accounted for. This accounting treatment requires that the carrying amount of embedded derivatives be marked-to-market at each balance sheet date and carried at fair value. In the event that the fair value is recorded as a liability, the change in fair value during the period is recorded in the Statement of Operations as either income or expense. Upon conversion, exercise or modification to the terms of a derivative instrument, the instrument is marked to fair value at the conversion date and then the related fair value is reclassified to equity.

In circumstances where the embedded conversion option in a convertible instrument is required to be bifurcated and there are also other embedded derivative instruments in the convertible instrument that are required to be bifurcated, the bifurcated derivative instruments are accounted for as a single, compound derivative instrument.

The classification of financial instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period. Equity instruments that are initially classified as equity that become subject to reclassification are reclassified to liability at the fair value of the instrument on the reclassification date. Derivative instrument liabilities will be classified in the balance sheet as current or non-current based on whether or not net-cash settlement of the derivative instrument is expected within 12 months of the balance sheet date.

Management must determine whether an instrument (or an embedded feature) is indexed to the Company’s own stock. An entity should use a two-step approach to evaluate whether an equity-linked financial instrument (or embedded feature) is indexed to its own stock, including evaluating the instrument’s contingent exercise and settlement provisions. This exercise affects the accounting for (i) certain freestanding warrants that contain exercise price adjustment features and (ii) convertible notes containing full-ratchet and anti-dilution protections (iii) certain free standing warrants that contain contingently puttable cash settlement.

Loss per Common Share

Basic loss per share is computed by dividing loss attributable to common stockholders by the weighted average number of common shares outstanding for the period. If applicable, diluted earnings per share reflect the potential dilution of securities that could share in the earnings (loss) of the Company. The common shares potentially issuable on conversion of outstanding convertible debentures, warrants and stock options are anti-dilutive and have not been included in the calculation.

NOTE 5:

DERIVATIVE LIABILITY

A summary of quantitative information with respect to valuation methodology and significant unobservable inputs used for the Company’s common stock purchase warrants that are categorized within Level 3 of the fair value hierarchy for the years ended 2015 and 2014 is as follows:


Stock Purchase Warrants	Weighted Average Inputs for the Period
Date of valuation	For the Year Ending December 31, 2015			For the Year Ending December 31, 2014
Strike price	$	0.74		$	10.70

Volatility (annual)		155	%		166	%

Risk-free rate		1.8	%		1.00	%

Contractual term (years)		4.2			2. 25

Dividend yield (per share)		0	%		0	%

The foregoing assumptions are recalculated every reporting period and are subject to change based primarily on management’s assessment of the probability of the events described occurring. Accordingly, changes to these assessments could materially affect the valuations.

Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis

Financial assets and liabilities measured at fair value on a recurring basis are summarized below and disclosed on the balance sheet under Derivative liability – warrants:


	As of December 31, 2015

There were no transfers between Level 1, 2 or 3 during the year ended December 31, 2015.

The following table presents changes in Level 3 liabilities measured at fair value for the year ended December 31, 2015:


	Derivative liability – warrants

Balance – December 31, 2014	$	9,000

Additions during the period		15,446,000

Settlement of debt		(16,835,000	)

Change in fair value of warrant liability		27,873,000


Balance – December 31, 2015	$	26,493,000

The valuation of warrants is subjective and is affected by changes in inputs to the valuation model including the price per share of common stock, the historical volatility of the stock price, risk-free rates based on U. S. Treasury security yields, the expected term of the warrants and dividend yield. Changes in these assumptions can materially affect the fair value estimate. The Company could ultimately incur amounts to settle the warrant at a cash settlement value that is significantly different than the carrying value of the liability on the financial statements. The Company will continue to classify the fair value of the warrants as a liability until the warrants are exercised, expire, or are amended in a way that would no longer require these warrants to be classified as a liability. Changes in the fair value of the common stock warrants liability are recognized as a component of other income (expense) in the Statements of Operations.

The net cash settlement value at the time of any future transactions, where the Company consolidates or merges with another entity, will depend upon the value of the following inputs at that time: the consideration value per share of the Company’s common stock, the volatility of the Company’s common stock, the remaining term of the warrant from announcement date, the risk-free interest rate based on U. S. Treasury security yields, and the Company’s dividend yield. The warrant requires use of a volatility assumption equal to the greater of 100% and the 100-day volatility function determined as of the trading day immediately following announcement of a Fundamental Transaction.

Pursuant to a placement agent agreement, the Company agreed to issue warrants to purchase 366,000 common shares with substantially the same terms as the January 2015 Warrants and pay a 7% finders fee on gross proceeds from the sale of securities.

In March, 2015, the Company entered into a Securities Purchase Agreement with certain accredited investors for the sale of 5,000,000 units at a purchase price of $0.20 per unit, for a total purchase price of approximately $950,000, net of finders’ fee and offering expenses of approximately $50,000. Each unit consisting of (i) one share of the Company’s Common Stock, (ii) one Series A warrant to purchase one share of common stock, (iii) one Series B warrant to purchase one share of common stock (iv) one Series C warrant to purchase one share of common stock, (v) one Series D warrant to purchase one share of common stock, and (vi) one Series E warrant to purchase one share of common stock (the Series A, B, C, D and E warrants are hereby collectively referred to as the “March 2015 Warrants”). The March 2015 Warrants have substantially the same terms as the January 2015 Warrants.

Pursuant to a placement agent agreement, the Company agreed to issue warrants to purchase 125,000 common shares with substantially the same terms as the March 2015 Warrants and pay a 3.5% finders fee on gross proceeds from the sale of securities.

Initial Fair Value of Warrants Issued

Pursuant to ASC 480-10 Distinguishing liabilities from equity and ASC 815-40 Contracts in an Entity’s Own Equity, the common stock purchase warrants are classified as a derivative liability as the Company cannot control their ability to gross settle the financial instruments with registered securities. The fair value of the warrants issued pursuant to the January and March 2015 stock purchase agreement was $9,313,000. The weighted average inputs include contractual term of 5.0 years, volatility of 158% and risk free rate of 1.2%.

May 2015 Restructuring agreement

In May 2015, the Company entered into a restructuring agreement with the investors of the January 2015 and March 2015 private placements, where:

•

The exercise price of the Series A warrants was changed from $1.50 per warrant to $0.10 per warrant,

•

The exercise price of Series B warrants was changed from $0.40 per warrant to $0.20 per warrant,

•

Each warrant of Series B existing prior to the restructuring agreement was replaced with two warrants of such series,

•

The exercise price of the Series C warrants was changed from $1.00 per warrant to $0.50 per warrant, and

•

Each warrant of Series C existing prior to the restructuring agreement was replaced with two warrants of such series.

As a result of the restructuring agreement, the Company issued an additional 12,320,000 Series B warrants and 12,320,000 Series C Warrants. The fair value of the warrants issued pursuant to the May 2015 restructuring agreement was $6,133,000. The weighted average inputs include contractual term of 2.46 years, volatility of 141% and risk free rate of 1.5%.

Management Compensation

In November, 2015, the Company entered into an employment agreement with Dr. Glynn Wilson, the Company’s Chief Executive Officer, President and Chairman of the Company. As part of the agreement, the Company granted Dr. Wilson 315,000 shares of unregistered common stock, fully vested. As of December 31, 2015, the shares have not been issued. Accordingly, the fair value of the common stock of approximately $191,000 was accounted for as an accrued liability.

Income Taxes

NOTE 9:

INCOME TAXES

The company has no income tax expense due to operating losses incurred for the years ended December 31, 2015 and 2014. Approximately $1.6 million in non-qualified stock options were cancelled during 2015 due to terminations that resulted in a reversal of the deferred tax asset of approximately $0.52 million. The cancellations did not result in a book income for December 31, 2015.

The effects of temporary differences that give rise to significant portions of the deferred tax assets as of December 31, 2015 and 2014 are as follows:


	Year Ended December 31, 2015			Year Ended December 31, 2014

Deferred tax assets:
Net operating loss carryforwards	$	8,359,000		$	10,433,000
Stock-based compensation		1,897,000			1,871,000
License agreements		268,000			—
Research and development		117,000			—
Technology licensing fee		185,000			167,000

Total deferred tax assets		10,826,000			12,471,000
Valuation allowance		(10,826,000	)		(12,471,000	)

Deferred tax assets, net of valuation allowance	$	—		$	—

The Company assesses the likelihood that deferred tax assets will be realized. To the extent that realization is not likely, a valuation allowance is established. Based upon the history of losses, management believes that it is more likely than not that future benefits of deferred tax assets will not be realized and has established a full valuation allowance for the years ended December 31, 2015 and 2014. The valuation allowance decreased by $1.6 million as of December 31, 2015. The Company has research and development tax credit carryforwards of $117,000 to offset future federal income taxes. The research and development tax credit carryforwards begin to expire in 2029.

The Company has approximately $24,123,000 of federal and $4,336,000 of state NOLs that may be available to offset future taxable income, if any. The federal net operating loss carryforwards, if not utilized, will expire between 2029 and 2035. The state net operating loss carryforwards, if not utilized, will expire in 2035.

In accordance with Section 382 of the Internal Revenue code, the usage of the Company’s net operating loss carryforwards may be limited in the event of a change in ownership. A full Section 382 analysis has not been prepared and NOLs could be subject to limitation under Section 382.

For the years ended December 31, 2015 and 2014, the expected tax expense (benefit) based on the U. S. federal statutory rate is reconciled with the actual tax provision (benefit) as follows:


	Year Ended December 31, 2015			Year Ended December 31, 2014
U. S. federal statutory rate	$	(11,582,000	)	$	(10,449,000	)

Income tax provision (benefit)	$	—		$	—

ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more-likely-than-not to be sustained upon examination by taxing authorities. As of December 31, 2015 and 2014, there were no unrecognized tax benefits. The Company recognizes accrued interest and penalties as income tax expense. No amounts were accrued for the payment of interest and penalties at December 31, 2015 and 2014. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position in the next year.

- Definition

Tabular disclosure of warrants or rights issued. Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.
