Nature of Operations [Text Block]

(1)	Company Overview

Biota Pharmaceuticals, Inc., together with its wholly owned subsidiaries (“Biota”, or the “Company”) is a biopharmaceutical company focused on the discovery and development of products to prevent and treat serious and potentially life-threatening infectious diseases. The Company has been incorporated in the state of Delaware since 1969 and its corporate headquarters are located in Alpharetta, Georgia.

The Company is currently focused on developing oral, small molecule antiviral compounds to treat a number of respiratory-related infections. The Company recently initiated a Phase 2b clinical trial (named SPIRITUS), which is a randomized, double-blind, placebo-controlled dose-ranging study of BTA-798, also known as vapendavir, in moderate and severe asthmatic patients at risk of loss of asthma control and exacerbations due to presumptive human rhinovirus (“HRV”) infection. The Company has successfully completed two other Phase 2 trials of vapendavir to-date. In addition, the Company is developing laninamivir octanoate, a long-acting neuraminidase inhibitor (“NI”) for the treatment of influenza A and B. On August 1, 2014, the Company reported top-line safety and efficacy results from a randomized, double-blind, placebo-controlled, parallel-arm Phase 2 clinical trial (named IGLOO), comparing the safety and efficacy of a 40 mg and an 80 mg dose of laninamivir octanoate to placebo. As compared to placebo, neither the 40 mg nor the 80 mg cohort achieved a statistically significant reduction in the median time to alleviation of all influenza associated symptoms, the primary endpoint, as measured by the Flu-iiQ patient-recorded outcome questionnaire. Certain important secondary endpoints, including quantitative viral shedding, and secondary bacterial infections, as well as the time to alleviation of systemic symptoms, did achieve statistically significant results for laninamivir octanoate treated cohorts compared to placebo.

In addition to these Phase 2 clinical-stage development programs, the Company is also developing orally bioavailable F and non-F protein compounds for the treatment of respiratory syncytial virus (“RSV”) infections in children, the elderly and immune-compromised patients. The Company recently completed the requisite preclinical studies needed to support the filing of an investigational new drug application (“IND”) for BTA-C585, its lead compound from our F-protein inhibitor program.

In March 2011, the Company was awarded a contract from the U.S. Office of Biomedical Advanced Research and Development Authority (“BARDA”) designed to provide up to $231 million in support of the development and submission for a New Drug Application (“NDA”) for laninamivir octanoate for the treatment of influenza A and B infections in the United States. On May 7, 2014, the U.S. Department of Health and Human Services (“HHS”) office of the Assistant Secretary for Preparedness and Response (“ASPR”) and BARDA notified the Company of its decision to terminate the contract for the convenience of the U.S. Government. The Company continues to work with BARDA to close out this contract, which involves finalizing invoices and billings and negotiating a final equitable termination settlement.

Although several of the Company’s influenza product candidates have been successfully developed and commercialized to date by other larger pharmaceutical companies under collaboration, license or commercialization agreements, the Company has not independently developed or received regulatory approval for any product candidate, and the Company does not currently have any sales, marketing or commercial capabilities. Therefore, it is possible that the Company may not successfully derive any significant product revenues from any product candidates that it is developing now, or may develop in the future. The Company expects to incur losses for the foreseeable future as it intends to support the clinical and preclinical development of its product candidates.

The Company plans to continue to finance its operations with (i) its existing cash, cash equivalents and investments, (ii) proceeds from existing or potential future royalty-bearing licenses or collaborative research and development arrangements, (iii) future equity and/or asset/debt financings, or (iv) other financing arrangements. The Company’s ability to continue to support its operations is dependent, in the near-term, upon managing its cash resources, continuing to receive royalty revenue under existing licenses, receiving final reimbursements from BARDA related to the close-out of its terminated contract, entering into future collaboration, license or commercialization agreements, successfully developing its product candidates, executing future financings and ultimately, upon obtaining approval of its products for sale and achieving positive cash flows from operations on a consistent basis. There can be no assurance that additional capital or funds will be available on terms acceptable to the Company, if at all, or that the Company will be able to enter into collaboration, license or commercialization agreements in the future, or that the Company will ever generate significant product revenue and become operationally profitable on a consistent basis.

Notes to Unaudited Condensed Consolidated Financial Statements

(for the quarterly period ended March 31, 2015)

(2)	Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. All material adjustments considered necessary for a fair presentation have been included. Certain information and footnote disclosure normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to instructions, rules and regulations prescribed by the U.S. Securities and Exchange Commission (“SEC”). Except as disclosed herein, there has been no material change in the information disclosed in the notes to the consolidated financial statements included in the Company’s Annual Report on Form 10-K that was filed with the SEC on September 30, 2014.

The unaudited interim consolidated financial statements include the accounts of the Company and all of its wholly owned subsidiaries. All inter-company transactions and balances are eliminated in consolidation.

Operating results for the nine months ended March 31, 2015 are not necessarily indicative of those in future quarters or the annual results that may be expected for the Company’s fiscal year ending June 30, 2015. For a more complete discussion of the Company’s significant accounting policies and other information, this report should be read in conjunction with the consolidated financial statements for the fiscal year ended June 30, 2014 included in the Company’s Annual Report on Form 10-K that was filed with the SEC on September 30, 2014.

The Company’s significant accounting policies have not changed since June 30, 2014, except as outlined below:

Recent Accounting Standards

In August 2014, the Financial Accounting Standards Board issued authoritative accounting guidance related to management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. Management’s evaluation should be based on relevant conditions and events that are known and reasonably knowable at the date that the financial statements are issued. In doing so, the amendments should reduce diversity in the timing and content of footnote disclosures. This guidance is effective for public and non-public entities for annual periods ending after December 15, 2016, and interim periods thereafter. Early adoption is permitted. The Company is currently assessing the expected impact, if any, that this Accounting Standards Update will have on its consolidated financial statements.

In May 2014, the Financial Accounting Standards Board issued authoritative accounting guidance related to revenue from contracts with customers. This guidance is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. This guidance is effective for annual reporting periods beginning after December 15, 2016 and early adoption is not permitted. The Company will adopt this guidance on July 1, 2017. Companies may use either a full retrospective or a modified retrospective approach to adopt this guidance. The Company is evaluating which transition approach to use and its impact, if any, on its consolidated financial statements.

Fair Value Disclosures [Text Block]

(3)	Fair Value Measurements

As per U.S. GAAP, a fair value hierarchy has been established which requires the Company to maximize the use of observable inputs, where available, and minimize the use of unobservable inputs when measuring fair value. The fair value hierarchy describes three levels of inputs that may be used to measure fair value:

	Level 1	Quoted prices in active markets for identical assets or liabilities.
	Level 2	Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in 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.

The following table sets forth the financial assets and liabilities that were measured at fair value on a recurring basis at March 31, 2015 and June 30, 2014, by level, within the fair value hierarchy. The assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

Biota Pharmaceuticals, Inc.

Notes to Unaudited Condensed Consolidated Financial Statements

(for the quarterly period ended March 31, 2015)

The Company’s long-term and short-term investments have been classified as Level 2, which have been initially valued at the transaction price and subsequently revalued at the end of each reporting period, utilizing a third party pricing service. The pricing service utilizes industry standard valuation models and observable market inputs to determine value that include surveying the bond dealer community, obtaining benchmark quotes, incorporating relevant trade data, and updating spreads daily. There have been no transfers of assets or liabilities between the fair value measurement classifications during the periods presented.

Cash equivalents consist primarily of money market funds. Short-term investments consist of securities with a maturity less than 365 days from the date of acquisition. Long-term investments consist of securities classified as available-for-sale and have maturities greater than 365 days from the date of acquisition. The Company’s short and long investments consist of U.S. agency securities, U.S. Treasury securities, and corporate notes.

The Company has had no realized gains or losses from the sale of investments for the nine months ended March 31, 2015. The following table shows the unrealized gains and losses and fair values for those investments as of March 31, 2015 and June 30, 2014, aggregated by major security type:

Basic and diluted net income (loss) per share has been computed based on net income (loss) and the weighted-average number of common shares outstanding during the applicable period. For diluted net loss per share, common stock equivalents (shares of common stock issuable upon the exercise of stock options and unvested restricted stock units) are excluded from the calculation as their inclusion would be anti-dilutive. The Company has excluded all anti-dilutive share-based awards to purchase common stock in periods indicating a loss, as their effect is anti-dilutive.

Royalty agreements

The Company entered into a worldwide royalty-bearing research and license agreement with GlaxoSmithKline (“GSK”) in 1990 for the development and commercialization of zanamivir, a neuraminidase inhibitor (“NI”) marketed by GSK as Relenza® to treat influenza. Under the terms of the agreement, the Company licensed zanamivir to GSK on an exclusive basis and is entitled to receive a royalty of 7% of GSK's annual net sales of Relenza

in the U.S., Europe, Japan and certain other countries as well as 10% of GSK's annual net sales of Relenza® in Australia, New Zealand, South Africa and Indonesia. The Relenza

patent portfolio is scheduled to expire as follows: December 2014 in the U.S., May 2015 in Australia and the major countries of the European Union (“EU”), and July 2019 in Japan. On August 25, 2014, GSK filed an appeal to the United States Patent Trial Appeal Board in relation to U.S. Patent Application No. 08/737,141. GSK has verified that the Company will continue to receive royalties on the net sales of Relenza

in the United States beyond December 2014 to the extent that this patent application remains pending or is ultimately issued. On March 19, 2015, the Company reported that the United States Patent Trial and Appeal Board had issued a decision denying the appeal and affirming the Examiner’s prima facie case of obviousness rejection under 35 United States Code (“U.S.C.”) 103(a). On May 7, 2015, the Company reported that it has filed a request with the United States Patent Trial and Appeal Board for a rehearing in relation to this pending patent application. The Company is unable at this time to determine the duration or the outcome of this appeal process, or how long this patent application will remain pending.

The Company also generates royalty revenue from the sale of laninamivir octanoate, which Daiichi Sankyo markets as Inavir

in Japan pursuant to a commercialization agreement that the Company entered into with Daiichi Sankyo in 2009. In September 2010, laninamivir octanoate (Inavir

) was approved for sale by the Japanese Ministry of Health and Welfare for the treatment of influenza in adults and children. In December 2013, Inavir

was also approved in Japan for the prevention of influenza in adults and children. Under the agreement, the Company currently receives a 4% royalty on net sales of Inavir

in Japan and is eligible to earn additional sales milestone payments. Under the a collaboration and license agreement entered into in 2003, the Company and Daiichi Sankyo have cross-licensed the world-wide rights to develop and commercialize the related intellectual property, and have agreed to share equally in any royalties, license fees, or milestone or other payments received from any third party licenses outside of Japan. Patents on laninamivir octanoate in Japan generally expire in 2024.

Collaborative and contract arrangements

In March 2011, the Company’s wholly owned subsidiary, Biota Scientific Management Pty Ltd., was awarded a contract by BARDA for the development of laninamivir octanoate on a cost-plus-fixed-fee basis, the total of which was not to exceed $231.2 million. BARDA is part of the U.S. Office of the ASPR within the HHS. The BARDA contract was designed to fund and provide the Company with all technical and clinical data and U.S. based manufacturing to support the filing of a NDA with the FDA for laninamivir octanoate. The performance period of the BARDA contract commenced on March 31, 2011, and was intended to continue for five years. On May 7, 2014 HHS/ASPR/BARDA notified the Company of its decision to terminate the contract for the convenience of the U.S. Government. The Company has been and continues to work with ASPR/BARDA to close out this contract, which at this time involves negotiating a final equitable termination settlement.

The Company was considered an active participant in the BARDA contract, with exposure to significant risks and rewards of commercialization relating to the development of laninamivir octanoate. Therefore, revenues from and costs associated with the close out of the contract are recorded and recognized on a gross basis in the consolidated statement of operations.

(7)	Share-based Compensation

For the three months ended March 31, 2015 and 2014, the Company recorded share-based compensation expense related to grants from equity incentive plans of $0.6 million and $0.5 million, respectively. For the nine months ended March 31, 2015 and 2014, the Company recorded share-based compensation expense related to grants from equity incentive plans of $1.6 million and $1.4 million, respectively. No income tax benefit was recognized in the statements of operations and no share-based compensation expense was capitalized as part of any assets for the three and nine months ended March 31, 2015 and 2014.

Stock Options

The fair value of each stock option award was estimated at its respective date of grant using the Black-Scholes method with the following assumptions:

	Three Months Ended						Nine Months Ended
	March 31,						March 31,
	2015			2014			2015			2014
Weighted-average risk-free interest rate		1.20	%		1.60	%		1.70	%		1.50	%
Dividend yield		—			—			—			—
Expected weighted-average volatility		.78			.78			.82			.78
Expected weighted-average life of options (years)		6.0			6.0			6.0			6.0
Weighted-average fair value of options granted	$	1.59		$	4.22		$	1.67		$	3.12

The risk-free interest rate is based on the expected life of the option and the corresponding U.S. Treasury bond, which in most cases is the five year U.S. Treasury bond. The expected term of stock options granted is derived from actual and expected option behavior and represents the period of time that options granted are expected to be outstanding. The Company uses historical data to estimate option exercise patterns and future employee terminations to determine expected life and forfeitures. Expected volatility is based on the historical volatility of the Company’s publicly-traded common stock.

In August 2014, the Company's Board of Directors made a determination that a performance-based milestone was not achieved and as a result, 413,675 performance-based stock options previously issued during fiscal 2014 would not vest and were cancelled.

The total intrinsic value of stock options exercised during the three month period ended March 31, 2015 was zero, and no cash proceeds were received by the Company. Further, no actual tax benefits were realized, as the Company currently records a full valuation allowance for all tax benefits due to uncertainties with respect to its ability to generate sufficient taxable income in the future.

The following tables summarize information relating to outstanding and exercisable options as of March 31, 2015:

Notes to Unaudited Condensed Consolidated Financial Statements

(for the quarterly period ended March 31, 2015)

In December 2013, the Company awarded 108,183 MSUs to employees that may vest on January 1, 2017. The vesting of these outstanding awards is subject to the respective employee’s continued employment through this settlement period. Further, the number of MSUs granted represents the target number of units that are eligible to be earned based on the attainment of certain market-based criteria involving the Company’s stock price. The number of MSUs actually earned, if any, is determined upon the vesting of the award. Participants may ultimately earn between 0% and 250% of the target number of units granted based on actual stock performance. Accordingly, additional MSUs may be issued or currently outstanding MSUs may be cancelled upon final determination of the number of awards earned. Compensation expense, including the effect of forfeitures, is recognized over the applicable service period.

As of March 31, 2015 there was $4.1 million of unrecognized share-based compensation expense related to all unvested share-based awards.

Unrecognized stock-based compensation expense for equity awards will be adjusted for future changes in estimated forfeitures. This balance is expected to be recognized over a weighted-average period of approximately two years.

Restructuring and Related Activities Disclosure [Text Block]

(8)	Restructuring Charges

The Company recognizes restructuring charges when a plan that materially changes the scope of its business or the manner in which that business is conducted is adopted and communicated to the impacted parties, and the expenses have been incurred or are reasonably estimable.

Fiscal 2014 Restructuring Activity

In the fourth quarter of fiscal 2014, the Company announced restructuring actions as a result of the termination of the BARDA contract for the convenience of the U.S. Government, including the closure of its operations in Melbourne, Australia.

The following is a reconciliation of the beginning and ending balances of the restructuring liability:

	Balance at							Balance at
	June 30,							March 31,
Fiscal 2014 Restructuring Plans:	2014		Provision		Payments			2015
Severance and employment costs		2.0		-		(1.6	)		0.4
Other charges related to office closure		0.0		0.3		-			0.3
Total restructuring costs	$	2.0	$	0.3	$	(1.6	)	$	0.7

During the third quarter of fiscal 2015, the Company recognized a provision $0.3 million for its leased facility in Melbourne, Australia due to its ceased use. As a result of the office closure, the Company sold and disposed of equipment within the facility and recognized a loss $0.2 million and received proceeds from the sale of $0.4 million. The remaining severance and other employment costs of approximately $0.4 million and $0.3 million related to the office closure are scheduled to be paid by the end of fiscal 2015.

Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Standards In August 2014, the Financial Accounting Standards Board issued authoritative accounting guidance related to management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. Management’s evaluation should be based on relevant conditions and events that are known and reasonably knowable at the date that the financial statements are issued. In doing so, the amendments should reduce diversity in the timing and content of footnote disclosures. This guidance is effective for public and non-public entities for annual periods ending after December 15, 2016, and interim periods thereafter. Early adoption is permitted. The Company is currently assessing the expected impact, if any, that this Accounting Standards Update will have on its consolidated financial statements. In May 2014, the Financial Accounting Standards Board issued authoritative accounting guidance related to revenue from contracts with customers. This guidance is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. This guidance is effective for annual reporting periods beginning after December 15, 2016 and early adoption is not permitted. The Company will adopt this guidance on July 1, 2017. Companies may use either a full retrospective or a modified retrospective approach to adopt this guidance. The Company is evaluating which transition approach to use and its impact, if any, on its consolidated financial statements.

- Definition

Investments in debt and equity securities which are categorized neither as held-to-maturity nor trading and which are intended to be sold or mature more than one year from the balance sheet date or operating cycle, if longer. Such securities are reported at fair value; unrealized gains (losses) related to Available-for-sale Securities are excluded from earnings and reported in a separate component of shareholders' equity (other comprehensive income), unless the Available-for-sale security is designated as a hedge or is determined to have had an other than temporary decline in fair value below its amortized cost basis. All or a portion of the unrealized holding gain (loss) of an Available-for-sale security that is designated as being hedged in a fair value hedge is recognized in earnings during the period of the hedge, as are other than temporary declines in fair value below the cost basis for investments in equity securities and debt securities that an entity intends to sell or it is more likely than not that it will be required to sell before the recovery of its amortized cost basis. Other than temporary declines in fair value below the cost basis for debt securities categorized as Available-for-sale that an entity does not intend to sell and for which it is not more likely than not that the entity will be required to sell before the recovery of its amortized cost basis are bifurcated into credit losses and losses related to all other factors. Other than temporary declines in fair value below cost basis related to credit losses are recognized in earnings, and losses related to all other factors are recognized in other comprehensive income.
