Notes to Financial Statements
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	1. Organization XBiotech Inc. (XBiotech or the Company) was incorporated in Canada on March 22, 2005. XBiotech USA Inc., a wholly-owned subsidiary of the Company, was incorporated in Delaware, United States in November 2007. XBiotech Schweiz AG, a wholly-owned subsidiary of the Company, was incorporated in Zug, Switzerland in August 2010. XBiotech Japan KK, a wholly-owned subsidiary of the Company, was incorporated in Tokyo, Japan in March 2013. XBiotech GmbH, a wholly-owned subsidiary of the Company, was incorporated in Germany in January 2014. Since its inception, XBiotech has focused on advancing technology to rapidly identify and clone antibodies from individuals that have resistance to disease. At the heart of the Company is a proprietary technical knowhow to translate natural human immunity into therapeutic product candidates. In 2005, the Company began to develop a new framework for commercial manufacturing, using technology that required less capital, fewer operators and provided greater flexibility than standard industry practices. With the manufacturing capability to produce its True Human ™ antibody therapy, in 2010 the Company began a clinical trial program. The first clinical trial program at MD Anderson Cancer Center began treating the sickest cancer patients irrespective of tumor type. Soon thereafter, the Company used the same antibody therapy in various clinical studies at treatment centers around the United States (U.S.) and abroad to investigate the antibody effect in patients that had vascular disease, leukemia, type 2 diabetes, psoriasis or acne. The Company’s headquarters are located in Austin, Texas. The Company continues to be subject to a number of risks common to companies in similar stages of development. Principal among these risks are the uncertainties of technological innovations, dependence on key individuals, development of the same or similar technological innovations by the Company’s competitors and protection of proprietary technology. The Company’s ability to fund its planned clinical operations, including completion of its planned trials, is expected to depend on the amount and timing of cash receipts from future collaboration or product sales and/or financing transactions. The Company believes that its cash and cash equivalents of $91.0 million at December 31, 2015, will enable the Company to maintain its current and planned operations for the foreseeable future.

Significant Accounting Policies [Text Block]

2. Significant Accounting Policies

Basis of Presentation

These consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States, or US GAAP.

Basis of Consolidation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions have been eliminated upon consolidation.

Use of Estimates

The preparation of financial statements in accordance with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported values of amounts in the financial statements and accompanying notes. Actual results could differ from those estimates.

Prior to its initial public offering on April 15, 2015, the Company utilized significant estimates and assumptions in determining the fair value of its common stock. The board of directors determined the estimated fair value of the Company’s common stock based on a number of objective and subjective factors, including the prices at which the Company sold shares of its common stock to third parties and external market conditions affecting the biotechnology industry sector.

Research and Development Costs

All research and development costs are charged to expense as incurred. Research and development costs include salaries and personnel-related costs, consulting fees, fees paid for contract clinical trial research services, the costs of laboratory consumables, equipment and facilities, license fees and other external costs. Costs incurred to acquire licenses for intellectual property to be used in research and development activities with no alternative future use are expensed as incurred as research and development costs.

Nonrefundable advance payments for goods or services to be received in the future for use in research and development activities are deferred and capitalized. The capitalized amounts are expensed as the related goods are delivered or the services are performed.

Income Taxes

The Company makes estimates and judgments in determining the need for a provision for income taxes, including the estimation of its taxable income or loss for the full fiscal year. The Company has accumulated significant deferred tax assets that reflect the tax effects of net operating losses and tax credit carryovers and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Realization of certain deferred tax assets is dependent upon future earnings. The Company is uncertain about the timing and amount of any future earnings. Accordingly, the Company offsets these deferred tax assets with a valuation allowance. The Company may in the future determine that certain deferred tax assets will likely be realized, in which case the Company will reduce its valuation allowance in the period in which such determination is made. If the valuation allowance is reduced, the Company may recognize a benefit from income taxes in its statement of operations in that period.

Share-Based Compensation

The Company accounts for its share-based compensation awards in accordance with ASC Topic 718,

Compensation-Stock Compensation

(“ASC 718”). ASC 718 requires all share-based payments to employees, including grants of employee stock options, to be recognized in the statements of operations based on their grant date fair values. For stock options granted to employees and to members of the board of directors for their services on the board of directors, the Company estimates the grant date fair value of each option award using the Black-Scholes option-pricing model. The use of the Black-Scholes option-pricing model requires management to make assumptions with respect to the expected life of the option and the expected volatility of the common stock consistent with the expected life of the option, risk-free interest rates and expected dividend yields of the common stock. For awards subject to service-based vesting conditions, the Company recognizes share-based compensation expense, equal to the grant date fair value of stock options, on a straight-line basis over the requisite service period.

Share-based compensation expense recognized for the years ended December 31, 2015, 2014 and 2013 was included in the following line items on the Consolidated Statements of Operations (in thousands).

	Year Ended December 31,
	2015		2014		2013
Research and development	$	2,204	$	1,303	$	551
General and administrative		2,203		5,717		188

Total share-based compensation expense	$	4,407	$	7,020	$	739

No related tax benefits were recognized for the years ended December 31, 2015, 2014 and 2013.

The fair value of each option is estimated on the date of grant using the Black-Scholes method with the following assumptions:

	Year Ended December 31,
	2015			2014			2013
Weighted-average grant date fair value per share		$17.95			$8.23			$11.37
Expected volatility	66%	–	71%	70%	–	73%		73%
Risk-free interest rate	1.07%	–	2.42%	0.69%	–	2.73%	2.04%	–	3.84%
Expected life (in years)	3	–	10	3	–	10	6.25	–	10
Dividend yield		–			–			–

Cash and Cash Equivalents

The Company considers highly liquid investments with a maturity of 90 days or less when purchased to be cash equivalents. Cash and cash equivalents consisted primarily of cash on deposit in U.S., German, Swiss and Canadian banks. Cash and cash equivalents are stated at cost which approximates fair value.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to credit risk consist primarily of cash and cash equivalents. The Company holds these investments in highly-rated financial institutions, and limits the amounts of credit exposure to any one financial institution. These amounts at times may exceed federally insured limits. The Company has not experienced any credit losses in such accounts and does not believe it is exposed to any significant credit risk on these funds. The Company has no off-balance sheet concentrations of credit risk, such as foreign currency exchange contracts, option contracts or other hedging arrangements.

Fair Value Measurements

The Company follows ASC Topic 820,

Fair Value Measurements and Disclosures

, which establishes a fair value hierarchy for those instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s own assumptions (unobservable inputs). The hierarchy consists of three levels:

•

Level 1—Unadjusted quoted prices in active markets for identical assets or liabilities.

•

Level 2—Quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability.

•

Level 3—Unobservable inputs that reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability in which there is little, if any, market activity for the asset or liability at the measurement date.

At December 31, 2015 and 2014, the Company did not have any assets or liabilities that were remeasured at fair value on a recurring basis. The carrying amounts reflected in the balance sheets for cash and cash equivalents, prepaid expenses and other current assets, accounts payable, and accrued expenses approximate their fair values at December 31, 2015and 2014, due to their short-term nature.

Property and Equipment

Property and equipment, which consists of land, furniture and fixtures, computers and office equipment, scientific equipment, leasehold improvements and vehicles are stated at cost and depreciated over the estimated useful lives of the assets, with the exception of land which is not depreciated, using the straight line method. The useful lives are as follows:

• Furniture and fixtures	7 years

• Office equipment	5 years

• Leasehold improvements	Shorter of asset’s useful life or remaining lease term

• Scientific equipment	5 years

• Vehicles	5 years

Costs of major additions and betterments are capitalized; maintenance and repairs, which do not improve or extend the life of the respective assets, are charged to expense as incurred. Upon retirement or sale, the cost of the disposed asset and the related accumulated depreciation are removed from the accounts and the resulting gain or loss is recognized.

Building Construction in Progress

Building construction in progress consists of the accumulated expenditures to build the new XBiotech manufacturing facility located in Austin, Texas, which includes the cost for land clearing, architecture design, engineering services, city permits, installation of utilities, construction materials and labor and construction management. Once the building is completed and placed into service, the Company will commence depreciation over its estimated useful life.

Impairment of Long-Lived Assets

The Company periodically evaluates its long-lived assets for potential impairment in accordance with ASC Topic 360,

Property, Plant and Equipment

. Potential impairment is assessed when there is evidence that events or changes in circumstances indicate that the carrying amount of an asset may not be recovered. Recoverability of these assets is assessed based on undiscounted expected future cash flows from the assets, considering a number of factors, including past operating results, budgets and economic projections, market trends and product development cycles. If impairments are identified, assets are written down to their estimated fair value. The Company has not recognized any impairment through December 31, 2015.

Deferred Offering Costs

Deferred offering costs, which consist of direct incremental legal, accounting and other professional service fees relating to the Company’s initial public offering (IPO) were capitalized. The deferred offering costs were offset against the proceeds from the IPO in April 2015.

Foreign Currency Transactions

Certain transactions are denominated in a currency other than the Company’s functional currency of the U.S. dollar, and the Company generates assets and liabilities that are fixed in terms of the amount of foreign currency that will be received or paid. At each balance sheet date, the Company adjusts the assets and liabilities to reflect the current exchange rate, resulting in a translation gain or loss. Transaction gains and losses are also realized upon a settlement of a foreign currency transaction in determining net loss for the period in which the transaction is settled.

Comprehensive Income (Loss)

ASC Topic 220,

Comprehensive Income

, requires that all components of comprehensive income (loss), including net income (loss), be reported in the financial statements in the period in which they are recognized. Comprehensive income (loss) is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources, including unrealized gains and losses on investments and foreign currency translation adjustments.

Segment and Geographic Information

Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker, or decision making group, in making decisions on how to allocate resources and assess performance. The Company’s chief operating decision maker is the Chief Executive Officer. The Company and the chief operating decision maker view the Company’s operations and manage its business as one operating segment. Substantially all of the Company’s operations are in the U.S. geographic segment.

Net Loss per Share

Net loss per share (“EPS”) is computed by dividing net loss by the weighted average number of common shares outstanding during each period. Diluted EPS is computed by dividing net loss by the weighted average number of common shares and common share equivalents outstanding (if dilutive) during each period. The number of common share equivalents, which include stock options, is computed using the treasury stock method.

Subsequent Events

The Company considered events or transactions occurring after the balance sheet date but prior to the date the consolidated financial statements are available to be issued for potential recognition or disclosure in its consolidated financial statements. We have evaluated subsequent events through the date of filing this Form 10-K.

Recent Accounting Pronouncements

In June 2014 the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2014-10,

Elimination of Certain Financial Reporting Requirements, including an Amendment to Variable Interest Entities Guidance in Topic 810 Consolidation

. These updates remove the definition of a development stage entity from the Master Glossary of the ASC, thereby removing the financial reporting distinction between development stage entities and other reporting entities from U.S. GAAP. In addition, the amendments eliminate the requirements for development stage entities to (1) present inception-to-date information in the statements of income, cash flows, and shareholder equity, (2) label the financial statements as those of a development stage entity, (3) disclose a description of the development stage activities in which the entity is engaged, and (4) disclose in the first year in which the entity is no longer a development stage entity that in prior years it had been in the development stage. This standard is effective for annual reporting periods beginning after December 15, 2014. The Company has early adopted this standard in the presentation of its financial statements.

In August 2014 the FASB issued ASU 2014-15

, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern

. The ASU is intended 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. For all entities, the ASU is effective for annual periods ending after December 15, 2016 and interim periods within annual periods beginning after December 15, 2016.

In February 2016 the FASB issued final guidance that will change the accounting for leases. The FASB issued final guidance that requires lessees to put most leases on their balance sheets but recognize expenses on their income statements in a manner similar to today’s accounting. The guidance also eliminates today’s real estate-specific provisions for all entities. For lessors, the guidance modifies the classification criteria and the accounting for sales-type and direct financing leases. All entities classify leases to determine how to recognize lease-related revenue and expense. Classification continues to affect what lessors record on the balance sheet. For calendar-year public business entities and certain calendar-year not-for-profit entities and employee benefit plans, the guidance is effective in 2019, and interim periods within that year. For other calendar-year entities, it is effective in 2020, and interim periods in 2021. Early adoption is permitted for all entities.

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

6. Common Stock Options

On November 11, 2005, the board of directors of the Company adopted a stock option plan (“the Plan”) pursuant to which the Company may grant incentive stock and non-qualified stock options to directors, officers, employees or consultants of the Company or an affiliate or other persons as the Compensation Committee may approve.

All options will be non-transferable and may be exercised only by the participant, or in the event of the death of the participant, a legal representative until the earlier of the options’ expiry date or the first anniversary of the participant’s death, or such other date as may be specified by the Compensation Committee.

The term of the options is at the discretion of the Compensation Committee, but may not exceed 10 years from the grant date. The options expire on the earlier of the expiration date or the date three months following the day on which the participant ceases to be a director, officer or employee of or consultant to the Company, or in the event of the termination of the participant with cause, the date of such termination.

The number of common shares reserved for issuance to any one person pursuant to this Plan shall not, in aggregate, exceed 5% of the total number of outstanding common shares. The exercise price per common share under each option will be the fair market value of such shares at the time of the grant. Upon stock option exercise, the Company issues new shares of common stock.

A summary of changes in common stock options issued under the Plan is as follows:

	Options			Exercise Price			Weighted- Average Exercise Price
Options outstanding at December 31, 2012		3,669,666		$0.60	–	$15.00	$	7.01

Options with an intrinsic value of $2.86, $2.90 and $2.51, became vested during 2015, 2014 and 2013, respectively. The total intrinsic value of options exercisable and total options outstanding at December 31, 2015 was $18,697,000 and $19,044,000, respectively. The total fair value of options vested during the years ended December 31, 2015, 2014 and 2013 was $$5,463,000, $6,999,000 and $632,500, respectively.

As of December 31, 2015, there was approximately $5.0 million of unrecognized compensation cost, related to stock options granted under the Plan which will be amortized to stock compensation expense over the next 2.02 years.

The following table summarizes information concerning outstanding options under the Plan as of December 31, 2015:

8. Income Taxes

The Company recorded no provision for income taxes for the years ended December 31, 2015, 2014 and 2013 due to the reported net losses in each year.

A reconciliation of the Company’s Canadian federal statutory income tax rate to the Company’s effective income tax rate is as follows for the years ended December 31, 2015, 2014 and 2013:

	2015			2014			2013
Income tax benefit computed at federal tax rate		26.0	%		26	%		13.50	%

Total		—	%		—	%		—	%

During the years ended December 31, 2015, 2014 and 2013, the Company had no interest and penalties related to income taxes.

As of December 31, 2015, and 2014, the Company has unused net operating losses of approximately $87.1 million .(approximately $70.8 million in Canada, $11.7 million in the U.S., $4.0 million in Germany and $0.6 million in Switzerland and Japan) and $62.6 million (approximately $51.2 million in Canada, $9.7 million in the U.S., $1.1 million in Germany and $0.6 million in Switzerland and Japan) respectively available to reduce taxable income of future years. The net operating losses begin to expire in 2018.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The Company has established a valuation allowance due to uncertainties regarding the realization of deferred tax assets based upon the Company’s lack of earnings history. Significant components of the Company’s deferred tax assets and liabilities as of December 31, 2015, 2014 and 2013 as follows (in thousands):

	2015			2014			2013
Deferred tax assets:
Noncapital losses	$	23,038		$	16,901			8,820

Net deferred tax asset including valuation allowance	$	—		$	—		$	—

The valuation allowance increased by approximately $10.3 and $9.4 million during the year ended December 31, 2015 and 2014 respectively.

The Company applies the accounting guidance in ASC 740 related to accounting for uncertainty in income taxes. The Company’s reserves related to taxes are based on a determination of whether, and how much of, a tax benefit taken by the Company in its tax filings or positions is more likely than not to be realized following resolution of any potential contingencies present related to the tax benefit. As of December 31, 2015 and 2014, the Company had no unrecognized tax benefits.

The Company files federal income tax returns in Canada, US, Switzerland, Germany, and Japan. The Company also files income tax returns in the state of Texas in the US. The statute of limitations for assessment by local taxing authorities is open for tax years ended after December 2011. There are currently no federal or state income tax audits in progress.

On January 12, 2008, the Company entered a lease agreement to lease its facility in Austin, Texas, U.S. On September 15, 2010, the Company entered into a second lease agreement to lease additional space in Austin, TX, U.S. Both leases expired in 2013. On March 20, 2013, the company extended the lease for another 21 months with the same terms and rental rates as the current leases. On February 28, 2015, the Company extended the leases for another four years with two years early termination right. Rent expense was approximately $688,000, $535,000 and $553,000 for the years ended December 31, 2015, 2014 and 2013, respectively.

XBiotech Corporate officers, Queena Han (VP of Finance) and John Simard (President and CEO), along with XBiotech Inc. were named defendants in securities class action civil suits filed in federal court at the U.S. District Court for the Western District of Texas, in Austin, Texas and state court at the Los Angeles County Superior Court, in California. In the California action, the underwriter WR Hambrecht & Co., LLC is also named as a defendant. These civil suits were filed on December 1, 2015. The foundation for both suits are similar in that the plaintiffs allege the officers of the company made false and misleading statements, violating the securities laws, in the IPO documents in April 2015. Specifically, these alleged false statements in the IPO documents are in relation to the European Phase III clinical trial for Xilonix™. The allegations focus on a press release posted by XBiotech on November 23, 2015 explaining certain issues with patient data. Plaintiffs allege the company knew of these issues during the IPO and neglected to disclose them in supporting documentation filed with the SEC. As a result of the news release, XBiotech (traded on the Nasdaq) stock tumbled. The resulting securities class action lawsuits are seeking relief for plaintiffs who report financial losses due to the alleged false and misleading statements. Both lawsuits are in the early procedural stages. As of February 2016, a lead plaintiff was assigned in the Texas case with the amended complaint scheduled to be filed with the court in April 2016. In California, motions to challenge venue and personal jurisdiction are due, by defendants, to the court in May 2016.
