Independent Auditor's Report
To the Board of Directors and Stockholders of
DFINE, Inc.
We have audited the accompanying consolidated financial statements of DFINE, Inc. and its subsidiary, which comprise the consolidated balance sheets as of December 31, 2015 and 2014, and the related consolidated statements of comprehensive loss, of convertible preferred stock and stockholders’ equity (deficit) and of cash flows for the years then ended.
Management's Responsibility for the Consolidated Financial Statements
Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with accounting principles generally accepted in the United States of America; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.
Auditor's Responsibility
Our responsibility is to express an opinion on the consolidated financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free from material misstatement.
An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on our judgment, including the assessment of the risks of material misstatement of the consolidated financial statements, whether due to fraud or error. In making those risk assessments, we consider internal control relevant to the Company's preparation and fair presentation of the consolidated financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of DFINE, Inc. and its subsidiary as of December 31, 2015 and 2014, and the results of their operations and their cash flows for the years then ended in accordance with accounting principles generally accepted in the United States of America.
Emphasis of Matter
The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has suffered recurring losses from operations and negative cash flows from operations that raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Our opinion is not modified with respect to this matter.

DFINE, Inc.
Notes to Consolidated Financial Statements
December 31, 2015 and 2014

1. | The Company

DFINE, Inc. (the “Company”) was incorporated in the state of Delaware on April 8, 2004. The Company is a medical device company that develops and markets therapeutic devices that treat vertebral compression fractures and other disorders of the spine in a minimally invasive manner to improve quality of life.
The Company has incurred operating losses and negative cash flows from operations since its inception. At December 31, 2015, the Company had an accumulated deficit of $149.3 million. The Company has financed operations to date primarily through private placement of equity securities and debt agreements. The Company expects its operating losses and negative cash flows to continue into the foreseeable future as it continues to commercialize its products. The Company’s management plans to expand commercial activities to grow revenues, manage expenses and obtain additional funds through the issuance of debt. The Company may need to obtain additional financing and there is no assurance that the Company will be successful in obtaining additional financing on favorable terms or at all. Failure to successfully commercialize its products, manage discretionary expenditures or raise additional financing, as required, may adversely impact the Company’s ability to achieve its intended business objectives. These factors raise substantial doubt about the Company’s ability to continue as a going concern. The financial statements do not contain any adjustments that might result from the outcome of this uncertainty.

2. | Summary of Significant Accounting Policies

Basis of Consolidation
The consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, DFINE Europe GmbH. All intercompany balances and transactions have been eliminated in consolidation.
Foreign Currency Translation
The foreign subsidiary's functional currency is its local currency. The gains and losses resulting from translating the foreign subsidiary's financial statements into U.S. dollars have been reported in accumulated other comprehensive loss within stockholders' deficit. All asset and liability accounts are translated at current period end exchange rates. Revenues and expenses are translated at average exchange rates in effect during the period. Foreign currency transaction gains and losses are included in the statements of comprehensive loss and have not been significant for the years presented.
Use of 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 disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Fair Value of Financial Instruments
For financial instruments consisting of cash equivalents, accounts receivable, accounts payable and accrued liabilities included in the Company’s financial statements, the carrying amounts approximate fair value due to their short maturities. Based on the borrowing rates available to the Company for loans with similar terms and maturities, the carrying value of the borrowings approximates their fair value (Level 2 within the fair value hierarchy). The carrying amounts of the convertible preferred stock warrant liabilities represent their estimated fair value (Level 3 within the fair value hierarchy).

DFINE, Inc.
Notes to Consolidated Financial Statements
December 31, 2015 and 2014
Concentration of Credit Risks and Other Risks and Uncertainties
The Company’s cash and cash equivalents are maintained with four financial institutions. Deposits in those institutions may exceed the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand and are maintained with reputable financial institutions and therefore bear minimal credit risk.
The Company is subject to risks common to companies in the medical device industry including, but not limited to, new technological innovations, dependence on key personnel, dependence on key suppliers, protection of proprietary technology, product liability and compliance with government regulations. To sustain profitable operations, the Company must successfully design, develop, manufacture and market its products. There can be no assurance that current products will continue to be accepted in the marketplace, nor can there be any assurance that any future products can be developed or manufactured at an acceptable cost and with appropriate performance characteristics, or that such products will be successfully marketed, if at all. These factors could have a material adverse effect on the Company’s future financial results, financial position and cash flows.
The Company is dependent on two vendors for the manufacture and supply of the Company’s products and any delay or failure to adequately supply the product by the vendors could have a material adverse impact on the Company.
Future products developed by the Company may require approvals or clearances from the U.S. Food and Drug Administration or other international regulatory agencies prior to commercial sales. There can be no assurance that the Company’s products will continue to meet the necessary regulatory requirements. If the Company were to be denied or was delayed in receiving such approvals or clearances, it may have a materially adverse impact on the Company.
Cash and Cash Equivalents
The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.
Restricted Cash
At December 31, 2015 and 2014, cash of $100,696 and $100,626, respectively, was restricted from withdrawal and held by financial institutions in the form of certificates of deposit. These certificates of deposit serve as the security deposit on the Company's facility lease.
Accounts Receivable
Accounts receivable are typically unsecured and represent amounts due from customers. The Company evaluates customer credit and maintains reserves for potential credit losses. The allowance for uncollectible accounts receivable is based on the Company’s historical bad debt experience and on management’s evaluation of the Company’s ability to collect individual outstanding balances. The allowance for doubtful accounts was $219,316 and $234,902, respectively, at December 31, 2015 and 2014.
Inventories
Inventories are stated at the lower of cost (determined using average cost), or market (estimated net realizable value). As of December 31, 2015 and 2014, the Company’s inventories consisted of parts and medical equipment. The Company periodically assesses the recoverability of all inventories, including raw materials and finished goods, to determine whether adjustments for impairment are required. Inventory that is obsolete or in excess of forecasted usage is written down to its estimated net realizable value based on assumptions about future demand and market

conditions. Inventory write-downs are charged to cost of revenues and establish a new cost basis for the inventory.
Provisions for excess and obsolete inventory were $169,893 and $136,571 in the years ended December 31, 2015 and 2014, respectively.
Property and Equipment
Property and equipment are stated at cost. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets, generally between three and seven years, or the lease term of the respective assets, whichever is lower. Maintenance and repairs are charged to expense as incurred, and improvements and betterments are capitalized. When assets are retired or otherwise disposed, the cost and accumulated depreciation and amortization are removed from the balance sheet and any resulting gain or loss is reflected in operations in the period realized.
Accounting for Long-lived Assets
The Company reviews property and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability is measured by comparison of the carrying amount to the future net cash flows which the assets are expected to generate. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the projected discounted future net cash flows arising from the asset. There have been no impairments of long-lived assets as of December 31, 2015.
Revenue Recognition
The company recognizes revenue in accordance with ASC 605, Revenue Recognition. The Company earns revenue from the sale of its products to distributors and hospitals. Revenue is recognized when the title and risk of ownership has been transferred, provided that persuasive evidence of an arrangement exists, the price is fixed and determinable, remaining obligations are insignificant and collectability is reasonably assured. Revenue is recorded net of customer and distributor discounts.
The company sells its products primarily to hospitals in the United States and European Union primarily through direct sales representatives. Revenue is recorded on sales to hospitals, net of discounts, upon the receipt of a customer purchase order, delivery of the product and when collection of the receivable is probable, at time of sale. Commissions paid to sales representatives are recorded as a sales and marketing expense. Sales to distributors are recorded when title and risk of loss transfer upon shipment, provided that all other revenue recognition criteria are met. The Company provides no price protection or stock rotation rights. All customers have a warranty for product defects in materials or workmanship but warranty expense has historically been insignificant and the Company does not provide a general right of return on the sale of its products.
Shipping Costs
Shipping costs charged to customers are included in revenues and the associated expense is included in cost of revenues in the consolidated statements of comprehensive loss.
Research and Development
The Company’s research and development costs are expenses as incurred. Research and development costs consist of payroll and personnel expenses, including stock-based compensation, laboratory supplies and consulting costs, as well as allocations of related facilities costs.

Notes to Consolidated Financial Statements
December 31, 2015 and 2014
Advertising Costs
Advertising costs, included in sales and marketing expenses, are expensed as incurred. Advertising costs were $18,456 and $130,608 for the years ended December 31, 2015 and 2014, respectively.
Warranty Costs
The Company offers a limited warranty on its products. Warranty expense has been insignificant for the years ended December 31, 2015 and 2014.
Income Taxes
The Company accounts for income taxes under the asset and liability method, which requires, among other things, that deferred income taxes be provided for temporary differences between the tax bases of the Company’s assets and liabilities and their financial statement reported amounts. In addition, deferred tax assets are recorded for the future benefit of utilizing net operating losses and research and development credit carryforwards. A valuation allowance is provided against deferred tax assets unless it is more likely than not that they will be realized.
Fair Value of Financial Instruments
ASC 820, Fair Value Measurement, defines fair value, establishes a framework for measuring fair value, and requires disclosure about fair value measurements. The standard provides a consistent definition of fair value which focuses on an exit price which is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The standard also prioritizes, within the measurement of fair value, the use of market-based information over entity specific information and establishes a three level hierarchy for fair value measurements based on the nature of inputs used in the valuation of an asset or liability as of the measurement date.
The three-level hierarchy for fair value measurements is defined as follows:

• | Level 1 - inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets;

• | Level 2 - inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset or liability, other than quoted prices, either directly or indirectly, including inputs in markets that are not considered to be active;

• | Level 3 - inputs to the valuation methodology are unobservable and significant to the fair value measurement.

An asset or liability’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.
Cash equivalents consisting of money market funds, commercial paper and U.S. Government Agency Securities are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency.
The convertible preferred stock warrant liability is classified within Level 3 of the fair value hierarchy because warrants are valued using the Black-Scholes pricing model, which uses unobservable inputs (see Note 6).

December 31, 2015 and 2014
As of December 31, 2015, financial assets and liabilities are measured and recognized at fair value on a recurring basis and classified under the appropriate level of the fair value hierarchy as described above and as follows:

Liabilities | Level 1 |  | Level 2 |  | Level 3 |  | Total
Convertible preferred stock warrant liability | — |  |  | — |  |  | 1,350,170 |  |  | 1,350,170 |

Accounting Pronouncements
In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers”. The amendment in this ASU provides guidance on the revenue recognition 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 core principle of this update provides guidance to identify the performance obligations under the contract(s) with a customer and how to allocate the transaction price to the performance obligations in the contract. It further provides guidance to recognize revenue when (or as) the entity satisfies a performance obligation. This ASU will be effective for the Company for annual periods beginning in 2018 and for interim periods beginning in 2019. The FASB has issued several updates to the standard which i) clarify the application of the principal versus agent guidance (ASU 2016-08); ii) clarify the guidance on inconsequential and perfunctory promises and licensing (ASU 2016-10) and iii) narrow scope improvements and practical expedients (ASU 2016-12). The Company is assessing the impact of this guidance and does not believe the adoption of this guidance will have a material impact to the Company's consolidated financial statements.
In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements-Going Concern”, with new guidance to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. The new guidance is effective for fiscal years beginning after December 15, 2016 with early application permitted. The Company is assessing the impact of this guidance and does not believe the adoption of this guidance will have a material impact to the Company’s consolidated financial statements.
In February 2016, the FASB issued ASU 2016-02, "Leases (ASC 842)", which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. ASC 842 supersedes the previous leases standard, ASC 840 Leases. The standard is effective on January 1, 2019, with early adoption permitted. The Company is in the process of evaluating the impact of this new guidance.
In March 2016, the FASB issued Accounting Standards Update (ASU) No. 2016-09, "Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting". This update simplifies the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. ASU 2016-09 is effective for private entities for annual periods beginning after December 15, 2017. The Company is in the process of evaluating the impact of this new guidance.

4. | Debt

On December 31, 2012, the Company entered into a four year financing arrangement with Silicon Valley Bank and Oxford Finance, LLC, which is comprised of an $11 million term loan and a $5 million revolving loan. The Company drew down the full term loan amount in three tranches of $5 million, $3 million and $3 million on December 31, 2012, May 3, 2013, and October 15, 2013, respectively. The loan agreement for each tranche provides for the Company to make interest-only payments at a stated rate of 7.98% per annum for 20 months starting on the date of each drawdown. Thereafter, the Company is obligated to pay monthly cash payments of principal and interest for a 30 month period with a balloon payment at loan maturity which is accreted as interest expense over the term of the loan. As of December 31, 2015, the Company had not drawn down any amount of the $5 million revolving loan.
On January 24, 2014, the Company entered into a Third Amendment to Loan and Security Agreement with Silicon Valley Bank and Oxford Finance, LLC. The amendment provided for two additional tranches of the term loan in amounts of $5 million and $2.5 million, respectively. The Company drew the first additional tranche of $5 million on March 31, 2015 at a rate of 8.01% per annum. The Company repaid the $16 million loan in December 2015.
On December 14, 2015, the Company refinanced its existing debt entering into a new five year financing agreement with Silicon Valley Bank and Oxford Finance, LLC. The new loan facility provides for $35 million in term loans, available for draw over three tranches, and a $5 million revolving loan, the utilization of which is based on a percentage of qualifying U.S. accounts receivables. On December 14, 2015, the Company drew down the first tranche of $25 million on the term loan, using a portion of the proceeds to repay the $16 million outstanding debt. The loan agreement provides for the Company to make interest-only payments at a stated rate of 7.98% per annum for 21 months starting on the date of first draw. Thereafter, the Company is obligated to pay monthly cash payments of principal and interest for a 36 month period with a 10% balloon payment at loan maturity which is accreted as interest expense over the term of the loan. The second tranche of $5 million may be drawn down within 30 days after the Company achieves trailing six month revenue of $20 million provided it’s before April 30, 2017 and there have been no events of default. Additionally, upon the second tranche draw, the interest only payment period may be extended from November 1, 2017 to November 1, 2018. The third tranche of $5 million may be drawn down within 30 days after the Company achieves trailing six month revenue of $22 million provided it’s before April 30, 2018 and there have been no events of default. As of December 31, 2015, the Company had only drawn the initial $25 million term loan tranche and had not drawn down any of the $5 million revolving loan.

5. | Commitments and Contingencies

On June 5, 2013, the Company, along with five other medical device companies, was named as a defendant in a patent infringement lawsuit by Orthophoenix, LLC. The Company reserves for costs relating to litigation and contingencies when a loss is probable and the amount can be reasonably estimated. As of December 31, 2015, the Company had accrued an estimated loss of $3,310,000 related to this litigation. The lawsuit was settled in April 2016 (see Note 10).
In May 2007, the Company leased office space in California under a noncancelable operating lease with escalating base rental, which was amended in May 2013 to extend the term of the lease through August 2016. The lease was subsequently extended to August 31, 2019 (see Note 10). In December 2008, the Company leased office space in Germany under a noncancelable operating

lease with escalating base rental, based on changes in a consumer price index, which was amended in May 2013 to extend the term of the lease through December 2017.
Future minimum lease payments under the noncancelable operating leases as of December 31, 2015 are as follows:

Year Ending December 31, |
2016 | $ | 466,741 |
2017 | 111,180 |
Total minimum lease payments | $ | 577,921 |

The Company recognizes rent expense on a straight-line basis over the lease term. Rent expense for the years ended December 31, 2015 and 2014 was $723,416 and $862,154, respectively.
Indemnification
The Company enters into indemnification provisions under its agreements with the other companies in the ordinary course of business, including business partners, contractors and parties performing its research and development. Pursuant to these arrangements, the Company indemnifies, hold harmless, and agrees to reimburse the indemnified parties for losses suffered or incurred by the indemnified party as a result of the Company's activities. The terms of these indemnification agreements are generally perpetual. The maximum potential amount of future payments the Company could be required to make under these agreements is not determinable. The Company has never incurred costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the Company believes the estimate of fair value of these agreements is minimal. The Company maintains commercial general liability insurance and product liability insurance to offset certain of its potential liabilities under these indemnification provisions.
Contingencies
The Company is subject to a wide variety of laws and regulations. Certain claims, suits and complaints in the ordinary course of business are pending or may arise. While there can be no assurance as to the ultimate outcome of any litigation involving the Company, the Company does not believe any pending legal proceedings will result in a judgment or settlement that would have a material adverse effect on the Company's financial position, results of operations or cash flows, except as disclosed above.

After the full payments to the Series F Preferred Stock, Series E Preferred Stock and Junior Preferred Stock as above, the entire remaining assets of the Corporation legally available for distribution shall be distributed pro rata to holders of the Common Stock of the Corporation in proportion to the number of shares of Common Stock held by them.

7. | Common Stock

The Company’s Certificate of Incorporation, as amended, authorized the Company to issue 450,000,000 shares of $0.001 par value common stock. Each share of common stock is entitled to one vote. The holders of common stock are also entitled to receive dividends whenever funds are legally available and when declared by the Board of Directors, subject to the prior rights of holders of all classes of stock outstanding. Since the Company’s inception, there have been no dividends declared.

8. | Stock Option Plans

In 2004, the Company established its 2004 Stock Option Plan (the “Prior Plan”) which provided for the granting of stock options to employees, directors, and consultants of the Company. Options granted under the Plan may be either incentive stock options (“ISOs”) or nonstatutory stock options (“NSOs”), as determined by the Administrator at the time of grant. The term of each option shall be stated in the Option Agreement; however, the term shall be no more than ten years from the date of the grant thereof. In the case of an ISO granted to an optionee who, at the time the option is granted, owns stock representing more than 10% of the voting power of all classes of stock of the Company or any parent subsidiary, the term of the option shall be five years from the date of grant or such shorter term as may be provided in the Option Agreement. Options granted under the Plan generally vest 25% one year after the vesting announcement date and ratably thereafter over the next 36 months. The 2004 Plan terminated in October 2014 and as such, no further options will be granted under this plan.
In October 2014, the Company adopted its 2014 Stock Plan (the “Plan”) which provides for the granting of various types of awards, including stock options, restricted stock purchase awards and restricted stock bonus awards (each, an “Award”) to employees, directors, and consultants (each, a “Grantee”) of the Company or its subsidiaries. Options granted under the Plan may be either ISOs or NSOs, as determined by the Administrator at the time of grant. However, ISOs may only be granted to employees of the Company or a subsidiary. In any calendar year, no more than 5,000,000 shares of Common Stock may be issued to a Grantee through stock options; provided, however, that an additional 5,000,000 shares may be granted pursuant to options in connection with a Grantee’s commencement of employment. In any calendar year, the Company may issue a maximum of 10,000,000 shares of Common Stock to a Grantee through restricted stock as performance-based compensation. The term of each Award shall be specified pursuant to a written agreement (an “Award Agreement”); however, the term shall be no more than ten years from the date of the grant thereof. In the case of an ISO granted to a Grantee who, at the time the option is granted, owns stock representing more than 10% of the voting power of all classes of stock of the Company, the term of the option shall be five years from the date of grant or such shorter term as may be provided in the Award Agreement. Options granted under the Plan generally vest 25% one year after the vesting announcement date and ratably thereafter over the next 36 months.
Activities under the Company’s stock option plans are as follows:

At December 31, 2014, 24,639,978 shares were exercisable under the Plan with a weighted average exercise price of $0.028 per share.
Stock-Based Compensation Associated with Awards to Employees
During the years ended December 31, 2015 and 2014, the Company granted stock options to employees to purchase 11,730,302 and 6,810,822 shares of common stock, respectively, with a weighted-average grant date common stock option fair value of $0.009 and $0.008 per option, respectively. Stock-based compensation expense recognized during the years ended December 31, 2015 and 2014 includes compensation expense for stock-based awards granted to employees based on the grant date fair value estimated in accordance with the provisions of ASC 718 of $108,929 and $165,779, respectively. As of December 31, 2015, there were total unrecognized compensation costs of $217,166 related to these stock options. These costs are expected to be recognized over a weighted average period of 2.37 years.
The Company estimated the fair value of stock options using the Black-Scholes option valuation model. The fair value of employee stock options is being amortized on a straight-line basis over the requisite service period of the awards. The fair value of the employee stock options was estimated using the following weighted-average assumptions:
22

DFINE, Inc.
Notes to Consolidated Financial Statements
December 31, 2015 and 2014

| Year Ended December 31,
| 2015 | 2014
Expected term (in years) | 6.20 | 5.08
Expected volatility | 49% | 34%
Average risk-free interest rate | 1.69% | 1.68%
Dividend yield | —% | —%

The expected term of stock options represents the weighted-average period the stock options are expected to remain outstanding and is based on the options vesting term, contractual terms, and industry peers as the Company did not have sufficient historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior. The expected stock price volatility assumption was determined by examining the historical volatilities for industry peers, as the Company did not have any trading history for the Company’s common stock. The Company will continue to analyze the historical stock price volatility and expected term assumptions as more historical data for the Company’s common stock becomes available. The risk-free rate assumption is based on the U.S. Treasury instruments whose term was consistent with the expected term of the Company’s stock options. The expected dividend assumption is based on the Company’s history and expectation of dividend payouts.
ASC 718 requires forfeitures to be estimated at the time of the grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those of estimates. Forfeitures are estimated based on an analysis of the Company’s historical option forfeitures.
Stock-Based Compensation Associated with Awards to Nonemployees
During the years ended December 31, 2015 and 2014, the Company granted options to purchase 172,073 and 118,887 shares of common stock, respectively, to consultants in exchange for services. Stock-based compensation expense related to stock options granted to nonemployees is recognized as the stock options are earned. The Company believes that the estimated fair value of the stock options is more readily measurable than the fair value of the services rendered.
The fair value of the stock options granted to nonemployees is calculated at each reporting date using the Black-Scholes pricing model using the following assumptions:

| Year Ended December 31,
| 2015 | 2014
Contractual term (in years) | 10 | 10
Expected volatility | 49% | 41%
Average risk-free interest rate | 2.18% | 2.26%
Dividend yield | —% | —%

The stock-based compensation expense will fluctuate as the estimated fair value of the common stock fluctuates. In connection with the grant of stock options to nonemployees, the Company recorded stock-based compensation expense of $39,470 and $39,983 for the years ended December 31, 2015 and 2014, respectively.

Total | $ | (12,527,431 | ) |  | $ | (11,947,136 | )

The tax effects of temporary differences that give rise to significant components of the deferred tax assets are as follows:

|  |  |  |  |  | December 31,
|  |  |  |  |  | 2015 |  | 2014
Net operating loss carryforwards | $ | 36,918,000 |  |  | $ | 32,994,000 |
Research and development credits | 779,000 |  |  | 769,000 |
Accrual, reserves and prepaids | 2,273,000 |  |  | 1,007,000 |
Total deferred tax assets |  |  | 39,970,000 |  |  | 34,770,000 |
Less: Valuation allowance | (39,970,000 | ) |  | (34,770,000 | )
Net deferred tax assets | $ | — |  |  | $ | — |

As of December 31, 2015, the Company had net operating loss carryforwards of approximately $86,213,000, $33,353,000 and $16,136,000 available to reduce future taxable income, if any, for federal, California state and Germany foreign income tax purposes, respectively. The net operating loss carryforwards will begin to expire in 2025 and 2015, respectively. Valuation allowances have been reserved, where necessary.
As of December 31, 2015, the Company also had federal and state research and development credit carryforwards of approximately $229,000 and $1,227,000, respectively. The federal research and development credit carryforwards expire beginning 2031 if not utilized and California credits carry forward indefinitely. Valuation allowances have been reserved, where necessary.
Utilization of the net operating loss carry forward may be subject to an annual limitation due to the ownership percentage change limitations provided by the Internal Revenue Code of 1986 and similar state provisions. The annual limitation may result in the expiration of the net operating loss before utilization.
ASC 740-10 prescribes a comprehensive model for the recognition, measurement, presentation and disclosure in financial statements of any uncertain tax positions that have been taken or expected to be taken on a tax return. As of December 31, 2014 and December 31, 2015, the Company recorded a $373,000 and $364,000 reduction to its deferred tax assets for unrecognized tax benefits, all of which has been fully offset by a valuation allowance. There was no interest or penalties accrued at December 31, 2014 and December 31, 2015. The Company does not anticipate any significant changes to unrecognized tax benefits in the next 12 months. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense.

December 31, 2015 and 2014
The Company has performed an analysis of ownership changes under Internal Revenue Code Section 382 and 383, and has determined that ownership changes have taken place which resulted in a limitation on the Company's ability to utilize its Net Operating Loss and R&D credit. As such, the Company's federal and state net operating loss as well as the federal R&D credit carryovers have been reduced accordingly.
The Company files income tax returns in the US federal jurisdiction, various states including California, and in Germany. As of December 31, 2015, all of the years remain open to examination by the federal and state tax authorities, for three or four years from the tax year in which net operating losses or tax credits are utilized. The Company is not currently subject to income tax examinations by any tax authority.
