| SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES |
Basis of Presentation
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) and with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) related to quarterly reports on Form 10-Q. Accordingly, they do not include all of the information and disclosures required by U.S. GAAP for a complete set of financial statements. These unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended April 30, 2016. The condensed consolidated balance sheet at April 30, 2016 has been derived from audited financial statements at that date. The unaudited financial information for the interim periods presented herein reflects all adjustments which, in the opinion of management, are necessary for a fair presentation of the financial condition and results of operations for the periods presented, with such adjustments consisting only of normal recurring adjustments. Results of operations for interim periods covered by this Quarterly Report on Form 10-Q may not necessarily be indicative of results of operations for the full fiscal year or any other interim period.
The unaudited condensed consolidated financial statements include the accounts of Peregrine and Avid. All intercompany accounts and transactions among the consolidated entities have been eliminated in the unaudited condensed consolidated financial statements.
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts, as well as disclosures of commitments and contingencies in the financial statements and accompanying notes. Actual results could differ materially from those estimates and assumptions.
Liquidity and Financial Condition
At October 31, 2016, we had $49,055,000 in cash and cash equivalents. We have expended substantial funds on the research and development of our product candidates, and funding the operations of Avid. As a result, we have historically experienced negative cash flows from operations since our inception and we expect negative cash flows from operations to continue until at least the fiscal year ending April 30, 2018 before we believe we can generate sufficient revenue from Avid’s contract manufacturing services to achieve profitability. Therefore, unless and until we are able to generate sufficient revenue from Avid’s contract manufacturing services or from the sale or licensing of our product candidates under development, we expect such losses to continue through at least the fiscal year ending April 30, 2018.
Our ability to continue to fund our operations is highly dependent on the amount of cash and cash equivalents on hand combined with our ability to raise additional capital to support our future operations through one or more methods, including but not limited to, (i) raising additional capital in the equity markets, (ii) generating additional revenue from Avid, or (iii) licensing or partnering our product candidates in development.
Historically, we have funded a significant portion of our operations through the issuance of equity. During the six months ended October 31, 2016, we raised $5,966,000 in aggregate gross proceeds from the sale of shares of our common stock and raised an additional $1,634,000 in aggregate gross proceeds from the sale of shares of our 10.5% Series E Convertible Preferred Stock (the “Series E Preferred Stock”) (Note 6). Subsequent to October 31, 2016 and through December 12, 2016, we raised an additional $1,670,000 in aggregate gross proceeds from the sale of shares of our common stock (Note 11). As of December 12, 2016, $105,345,000 remained available to us under our two effective shelf registration statements, which allows us from time to time to offer and sell shares of our common stock or Series E Preferred Stock, in one or more offerings, either individually or in combination.
Our ability to raise additional capital in the equity markets to fund our obligations in future periods is dependent on a number of factors, including, but not limited to, the market demand for our common stock or Series E Preferred Stock. The market demand or liquidity of our common stock and/or Series E Preferred Stock is subject to a number of risks and uncertainties, including but not limited to, negative economic conditions, adverse market conditions, adverse financial results, and negative research and development results. Furthermore, our ability to raise additional capital in the equity markets has been significantly impacted by the decline in the market price of our common stock following our announcement in February 2016 that we were discontinuing the Phase III SUNRISE trial. As a result, we have experienced a substantial decline in the amount of additional capital that we have been able to raise from the sale of shares of our common stock as compared to recent fiscal years. If the market price of our common stock does not improve significantly, we may not be able to rely on the sale of shares of our common stock to fund our operations to the extent we have in prior years. If we are unable to either (i) raise sufficient capital in the equity markets, (ii) generate additional revenue from Avid, or (iii) license or partner our products in development, or any combination thereof, we may need to delay, scale back, or eliminate some or all our research and development efforts, or restructure our operations, which may include delaying the planned expansion of our contract manufacturing business. In addition, even if we are able to raise additional capital, it may not be at a price or on terms that are favorable to us.
Cash and Cash Equivalents
We consider all short-term investments readily convertible to cash with an initial maturity of three months or less to be cash equivalents.
Restricted Cash
Under the terms of two separate operating leases related to our facilities, we are required to maintain, as collateral, letters of credit during the terms of such leases. At October 31, 2016 and April 30, 2016, we had restricted cash of $600,000, in aggregate, under these letters of credit.
Concentrations of Credit Risk and Customer Base
Financial instruments that potentially subject us to a significant concentration of credit risk consist of cash and cash equivalents, restricted cash and trade receivables. We maintain our cash and restricted cash balances primarily with one major commercial bank and our deposits held with the bank exceed the amount of government insurance limits provided on our deposits. We are exposed to credit risk in the event of default by the major commercial bank holding our cash and restricted cash balances to the extent of the cash and restricted cash amounts recorded on the accompanying interim unaudited condensed consolidated balance sheet.
Our trade receivables from amounts billed for contract manufacturing services provided by Avid have historically been derived from a small customer base. Most contracts require up-front payments and installment payments during the service period. We perform periodic evaluations of the financial condition of our customers and generally do not require collateral, but we can terminate any contract if a material default occurs. At October 31, 2016 and April 30, 2016, over 98% of our trade receivables were due from four customers.
In addition, contract manufacturing revenue generated by Avid has historically been derived from a small customer base (Note 9). These customers typically do not enter into long-term contracts because their need for drug supply depends on a variety of factors, including the drug’s stage of development, their financial resources, and, with respect to commercial drugs, demand for the drug in the market. Our future results of operations could be adversely affected if revenue from any one of our primary customers is significantly reduced or eliminated.
Revenue Recognition
We currently derive revenue from our contract manufacturing services provided by Avid. We recognize revenue in accordance with the authoritative guidance for revenue recognition when all of the following criteria are met: (i) persuasive evidence of an arrangement exists, (ii) delivery (or passage of title) has occurred or services have been rendered, (iii) the seller’s price to the buyer is fixed or determinable, and (iv) collectability is reasonably assured. We also comply with the authoritative guidance for revenue recognition regarding arrangements with multiple elements. Revenue arrangements with multiple elements are divided into separate units of accounting if certain criteria are met, including whether the delivered element has stand-alone value to the customer or licensing partner. When deliverables are separable, consideration received is allocated among the separate units based on their respective fair values, and the applicable revenue recognition criteria are applied to each of the separate units, which may require the use of significant judgement. Deliverables are considered separate units of accounting if (1) the delivered item(s) has value to the customer on a stand-alone basis and (2) the arrangement includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) is considered probable and substantially in our control.
Arrangement consideration is allocated at the inception of the agreement to all identified units of accounting based on their relative selling price. The relative selling price for each deliverable is determined using vendor specific objective evidence (“VSOE”) of selling price or third-party evidence of selling price if VSOE does not exist. If neither VSOE nor third-party evidence of selling price exists, we use our best estimate of the selling price for the deliverable. The amount of allocable arrangement consideration is limited to amounts that are fixed or determinable. The consideration received is allocated among the separate units of accounting, and the applicable revenue recognition criteria are applied to each of the separate units. Changes in the allocation of the sales price between delivered and undelivered elements can impact revenue recognition but do not change the total revenue recognized under any agreement.
Contract Manufacturing Revenue
Revenue associated with contract manufacturing services provided by Avid is recognized when all four of the aforementioned revenue recognition criteria have been met. For arrangements that include multiple elements, we follow the authoritative guidance for revenue recognition regarding arrangements with multiple deliverables, as described above.
On occasion, we receive requests from customers to hold product manufactured by Avid on a “bill-and-hold” basis. Revenue is recognized for such “bill-and-hold” arrangements in accordance with the authoritative guidance, which requires, among other things, the existence of a valid business purpose for the arrangement; the “bill-and-hold” arrangement is at the request of the customer; title and risk of ownership must pass to the customer; the product is complete and ready for shipment; a fixed delivery date that is reasonable and consistent with the customer’s business practices; the product has been separated from our inventory; and no further performance obligations by us exist.
In addition, we also follow the authoritative guidance when reporting revenue as gross when we act as a principal versus reporting revenue as net when we act as an agent. For transactions in which we act as a principal, have discretion to choose suppliers, bear credit and inventory risk and perform a substantive part of the services, revenue is recorded at the gross amount billed to a customer and costs associated with these reimbursements are reflected as a component of cost of sales for contract manufacturing services.
Any amounts received prior to satisfying our revenue recognition criteria are recorded as deferred revenue or customer deposits in the accompanying unaudited condensed consolidated financial statements. We also record a provision for estimated contract losses, if any, in the period in which they are determined.
Impairment
Long-lived assets are reviewed for impairment in accordance with authoritative guidance for impairment or disposal of long-lived assets. Long-lived assets are reviewed for events or changes in circumstances, which indicate that their carrying value may not be recoverable. Long-lived assets are reported at the lower of carrying amount or fair value less cost to sell. For the six months ended October 31, 2016 and 2015, there was no impairment of the value of our long-lived assets.
Fair Value Measurements
Fair value is defined as 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 guidance prioritizes the inputs used in measuring fair value into the following hierarchy:
As of October 31, 2016 and April 30, 2016, we do not have any Level 2 or Level 3 financial assets or liabilities and our cash equivalents, which are primarily invested in money market funds with one major commercial bank, are carried at fair value based on quoted market prices for identical securities (Level 1 input).
Customer Deposits
Customer deposits primarily represent advance billings and/or payments received from Avid’s third-party customers prior to the initiation of contract manufacturing services.
Research and Development Expenses
Research and development expenses primarily include (i) payroll and related costs, including share-based compensation associated with research and development personnel, (ii) costs related to clinical trials and preclinical testing of our technologies under development, (iii) costs to develop and manufacture the product candidates, including raw materials and supplies, product testing, depreciation, and facility related expenses, (iv) expenses for research services provided by universities and contract laboratories, including sponsored research funding, and (v) other research and development expenses. Research and development expenses are charged to expense as incurred when these expenditures relate to our research and development efforts and have no alternative future uses.
Clinical trial costs are a significant component of our research and development expenses. We have a history of contracting with third parties that perform various clinical trial activities on our behalf in the ongoing development of our product candidates. The financial terms of these contracts are subject to negotiations and may vary from contract to contract and may result in uneven payment flow. Expenses related to clinical trials are accrued based on our estimates and/or representations from third parties (including clinical research organizations) regarding services performed. If the contracted amounts are modified (for instance, as a result of changes in the clinical trial protocol or scope of work to be performed), we modify our accruals accordingly on a prospective basis. Revisions in the scope of a contract are charged to expense in the period in which the facts that give rise to the revision become reasonably certain. There were no material adjustments for a change in estimate to research and development expenses in the accompanying unaudited condensed consolidated financial statements for the three and six months ended October 31, 2016 and 2015.
Under certain research and development agreements, we are obligated to make certain advance payments, including nonrefundable amounts, for goods or services that will be used or rendered for future research and development activities and are deferred and capitalized as prepaid research and development expenses. These advance payments are recognized as an expense in the period the related goods are delivered or the related services are performed. We assess our prepaid research and development expenses for impairment when events or changes in circumstances indicate that the carrying amount of the prepaid expense may not be recoverable or provide future economic benefit.
In addition, under certain in-licensing agreements associated with the research and development of our product candidates, we are obligated to pay certain milestone payments based on potential clinical development and regulatory milestones. These milestone payments have no alternative future uses (in other research and development projects or otherwise) and therefore have no separate economic values and are expensed as research and development costs at the time the costs are incurred. We have no in-licensed product candidates that have alternative future uses in research and development projects or otherwise.
Share-based Compensation
We account for stock options and other share-based awards granted under our equity compensation plans in accordance with the authoritative guidance for share-based compensation. The estimated fair value of share-based payments to employees in exchange for services is measured at the grant date, using a fair value based method, such as a Black-Scholes option valuation model, and is recognized as expense on a straight-line basis over the requisite service periods. The fair value of modifications to share-based awards, if any, is generally estimated using a Black-Scholes option valuation model, unless a lattice model is required. Share-based compensation expense recognized during the period is based on the value of the portion of the share-based payment that is ultimately expected to vest during the period. As of October 31, 2016, there were no outstanding share-based awards with market or performance conditions.
Periodically, we grant stock options and other share-based awards to non-employee consultants, which we account for in accordance with the authoritative guidance for share-based compensation. The cost of non-employee services received in exchange for share-based awards are measured based on either the fair value of the consideration received or the fair value of the share-based award issued, whichever is more reliably measurable. In addition, guidance requires share-based compensation related to unvested options and awards issued to non-employees to be recalculated at the end of each reporting period based upon the fair market value on that date until the share-based award has vested, and any cumulative catch-up adjustment to share-based compensation resulting from the re-measurement is recognized in the current period (Note 7).
Basic and Dilutive Net Loss Per Common Share
Basic net loss per common share is computed by dividing our net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period excluding the dilutive effects of stock options, shares of common stock expected to be issued under our Employee Stock Purchase Plan (the “ESPP”), warrants, and Series E Preferred Stock outstanding during the period. Diluted net loss per common share is computed by dividing our net loss attributable to common stockholders by the sum of the weighted average number of shares of common stock outstanding during the period plus the potential dilutive effects of stock options, shares of common stock expected to be issued under our ESPP, warrants, and Series E Preferred Stock outstanding during the period. Net loss attributable to common stockholders represents our net loss plus Series E Preferred Stock accumulated dividends. Series E Preferred Stock accumulated dividends include dividends declared for the period (regardless of whether or not the dividends have been paid) and dividends accumulated for the period (regardless of whether or not the dividends have been declared).
The potential dilutive effect of stock options, shares of common stock expected to be issued under our ESPP, and warrants outstanding during the period are calculated in accordance with the treasury stock method, but are excluded if their effect is anti-dilutive. The potential dilutive effect of Series E Preferred Stock outstanding during the period was calculated using the if-converted method assuming the conversion of Series E Preferred Stock as of the earliest period reported or at the date of issuance, if later, but are excluded if their effect is anti-dilutive. However, because the impact of stock options, shares of common stock expected to be issued under our ESPP, warrants, and Series E Preferred Stock are anti-dilutive during periods of net loss, there was no difference between basic and diluted loss per common share amounts for the three and six months ended October 31, 2016 and 2015.
The calculation of weighted average diluted shares outstanding for the three and six-month periods ended October 31, 2016 and 2015 excludes the dilutive effect of the following weighted average outstanding stock options and shares of common stock expected to be issued under our ESPP as their impact are anti-dilutive during periods of net loss, resulting in an anti-dilutive effect:
The calculation of weighted average diluted shares outstanding for the three and six-month periods ended October 31, 2016 and 2015 also excludes the following weighted average outstanding stock options, warrants, and Series E Preferred Stock (assuming the if-converted method), as their exercise prices or conversion price were greater than the average market price of our common stock during the respective periods, resulting in an anti-dilutive effect:
Subsequent to October 31, 2016 and through December 12, 2016, we sold an aggregate of 5,376,255 shares of our common stock (Note 11), which are not included in the calculation of basic and dilutive net loss per common share for the three and six months ended October 31, 2016.
Pending Adoption of Recent Accounting Pronouncements
In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606): Revenue from Contracts with Customers, which amends the guidance in former ASC 605, Revenue Recognition, which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most current revenue recognition guidance. ASU No. 2014-09 is based on the principle that revenue is recognized to depict the transfer of 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 ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. ASU No. 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period, and entities can transition to the standard either retrospectively or as a cumulative-effect adjustment as of the date of adoption. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which defers the effective date of ASU No. 2014-09 by one year, but permits entities to adopt one year earlier if they choose (i.e., the original effective date). As such, ASU No. 2014-09 will be effective for annual reporting periods ending after December 15, 2017, which will be our fiscal year 2019 beginning May 1, 2018. We are currently in the process of evaluating the impact of adoption of ASU No. 2014-09 on our consolidated financial statements and related disclosures, including what transition method will be elected.
In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. ASU No. 2014-15 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. Substantial doubt about an entity’s ability to continue as a going concern exists when relevant conditions and events, considered in the aggregate, indicate that it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued (or available to be issued). ASU No. 2014-15 provides guidance to an organization’s management, with principles and definitions that are intended to reduce diversity in the timing and content of disclosures that are commonly provided by organizations in the financial statement footnotes. ASU No. 2014-15 is effective for annual reporting periods ending after December 15, 2016, which will be our fiscal year ending April 30, 2017, and to annual and interim periods thereafter. Early adoption is permitted. We have not yet determined the effect that the adoption of this guidance will have on the disclosures included in our consolidated financial statements as our analysis regarding our ability to continue as a going concern will be performed in conjunction with the preparation of our Annual Report on Form 10-K for the fiscal year ending April 30, 2017.
In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. ASU 2015-11 requires that for entities that measure inventory using the first-in, first-out method, inventory should be measured at the lower of cost and net realizable value. ASU 2015-11 defines net realizable value as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. ASU 2015-11 is effective for fiscal years beginning after December 15, 2016, which will be our fiscal year 2018 beginning May 1, 2017, and interim periods within those fiscal years. The amendments should be applied prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. We are currently in the process of evaluating the impact of adoption of ASU No. 2015-11 on our consolidated financial statements and related disclosures.
In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. Under existing standards, deferred taxes for each tax-paying jurisdiction are presented as a net current asset or liability and net long-term asset or liability. To simplify presentation, the new guidance will require that all deferred tax assets and liabilities, along with related valuation allowances, be classified as long-term on the balance sheet. As a result, each tax-paying jurisdiction will now only have one net long-term deferred tax asset or liability. The new guidance does not change the existing requirement that prohibits offsetting deferred tax liabilities from one jurisdiction against deferred tax assets of another jurisdiction. ASU No. 2015-17 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, which will be our fiscal year 2018 beginning May 1, 2017. We do not expect the adoption of ASU No. 2015-17 to have a material impact on our consolidated financial statements and related disclosures.
In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). ASU No. 2016-2 requires an entity to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU No. 2016-02 offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. ASU No. 2016-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, which will be our fiscal year 2020 beginning May 1, 2019. Early adoption is permitted. We are currently in the process of evaluating the impact of adoption of ASU No. 2016-02 on our consolidated financial statements and related disclosures.
In March 2016, FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718). ASU No. 2016-09 changes certain aspects of accounting for share-based payments to employees and involves several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Specifically, ASU No. 2016-09 requires that all income tax effects of share-based awards be recognized as income tax expense or benefit in the reporting period in which they occur. Additionally, ASU No. 2016-09 amends existing guidance to allow forfeitures of share-based awards to be recognized as they occur. Previous guidance required that share-based compensation expense include an estimate of forfeitures. ASU No. 2016-09 is effective for annual and interim periods beginning after December 15, 2016, which will be our fiscal year 2018 beginning May 1, 2017. Early adoption is permitted. We are currently evaluating the impact the adoption of ASU No. 2016-09 will have on our consolidated financial statements and related disclosures.
In November 2016, FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which addresses diversity in practice related to the classification and presentation of changes in restricted cash on the statement of cash flows. ASU No. 2016-18 will require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. ASU No. 2016-18 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, which will be our fiscal year 2019 beginning May 1, 2018. Early adoption is permitted. We are currently evaluating the impact the adoption of ASU No. 2016-18 will have on our consolidated financial statements and related disclosures. |

Trade receivables are recorded at the invoiced amount net of an allowance for doubtful accounts, if necessary. Other receivables are reported at amounts expected to be collected net of an allowance for doubtful accounts, if necessary. Trade and other receivables consist of the following:
______________ (1) Represents amounts billed for contract manufacturing services provided by Avid.
We continually monitor our allowance for doubtful accounts for all receivables. We apply judgment in assessing the ultimate realization of our receivables and we estimate an allowance for doubtful accounts based on various factors, such as, the aging of accounts receivable balances, historical experience, and the financial condition of our customers. Based on our analysis of our receivables as of October 31, 2016 and April 30, 2016, we determined that no allowance for doubtful accounts was necessary with respect to our trade and other receivables. |

| STOCKHOLDERS' EQUITY |
Sales of Common Stock and Preferred Stock
Our ability to continue to fund our operations is highly dependent on the amount of cash and cash equivalents on hand combined with our ability to raise additional capital to support our future operations through one or more methods, including but not limited to, issuing additional equity.

During the six months ended October 31, 2016, we issued shares of our common stock under the following agreements:

| SEGMENT REPORTING |
Our business is organized into two reportable operating segments and both operate in the U.S. Peregrine is engaged in the research and development of monoclonal antibodies for the treatment of cancer. Avid is engaged in providing contract manufacturing services for third-party customers on a fee-for-service basis while also supporting our internal drug development efforts.
The accounting policies of the operating segments are the same as those described in Note 2. We evaluate the performance of our contract manufacturing services segment based on gross profit or loss from third-party customers. However, our products in the research and development segment are not evaluated based on gross profit or loss, but rather based on scientific progress of the technologies. As such, gross profit or loss is only provided for our contract manufacturing services segment in the below table. All revenues shown below are derived from transactions with third-party customers.
Segment information is summarized as follows:
Revenue generated from our contract manufacturing services segment was derived from a limited number of customers. The percentages below represent revenue derived from each customer as a percentage of total contract manufacturing services revenue:
In addition, during the three and six months ended October 31, 2016 and 2015, contract manufacturing services revenue was derived solely from U.S. based customers.
Revenue generated from our products in our research and development segment during the six months ended October 31, 2015 was directly related to license revenue recognized under certain agreements with an unrelated entity.
Our long-lived assets are located in the U.S. and consist of leasehold improvements, laboratory equipment, furniture and fixtures, office equipment and software and are net of accumulated depreciation. Long-lived assets by segment consist of the following:

| Commitments and Contingencies Disclosure [Abstract] | |
| COMMITMENTS AND CONTINGENCIES |
In the ordinary course of business, we are at times subject to various legal proceedings and disputes. We make provisions for liabilities when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Such provisions are reviewed at least quarterly and adjusted to reflect the impact of any settlement negotiations, judicial and administrative rulings, advice of legal counsel, and other information and events pertaining to a particular case.
On October 10, 2013, a derivative and class action complaint, captioned Michaeli v. Steven W. King, et al., C.A. No. 8994-VCL, was filed in the Court of Chancery of the State of Delaware against certain of our executive officers and directors (collectively, the “Defendants”). On December 1, 2015, the plaintiffs filed an amended and supplemental derivative and class action complaint (the “Amended Complaint”). The Amended Complaint alleges that the Defendants breached their respective fiduciary duties in connection with certain purportedly improper compensation decisions made by our Board of Directors during the past four fiscal years ended April 30, 2015, including: (i) the grant of a stock option to Mr. King on May 4, 2012; (ii) the non-routine broad-based stock option grant to our directors, executives, all other employees and certain consultants on December 27, 2012; and (iii) the payment, during the past four fiscal years ended April 30, 2015, of compensation to our non-employee directors. In addition, the complaint alleges that our directors breached their fiduciary duty of candor by filing and seeking stockholder action on the basis of an allegedly materially false and misleading proxy statement for our 2013 annual meeting of stockholders. The plaintiffs are seeking, among other things, rescission of a portion of the stock option grant to Mr. King on May 4, 2012 and the stock options granted to the Defendants on December 27, 2012, as well as disgorgement of any excessive compensation paid to our non-employee directors during the four fiscal years ended April 30, 2015 and other monetary relief for our benefit. The Defendants filed their answer to the Amended Complaint on February 19, 2016. We believe that the Amended Complaint is without merit and intend to vigorously defend the action. In addition, due to the early stage of this matter, we cannot reasonably estimate the possible loss or range of loss, if any, that may result from this matter. |

Basis of Presentation
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) and with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) related to quarterly reports on Form 10-Q. Accordingly, they do not include all of the information and disclosures required by U.S. GAAP for a complete set of financial statements. These unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended April 30, 2016. The condensed consolidated balance sheet at April 30, 2016 has been derived from audited financial statements at that date. The unaudited financial information for the interim periods presented herein reflects all adjustments which, in the opinion of management, are necessary for a fair presentation of the financial condition and results of operations for the periods presented, with such adjustments consisting only of normal recurring adjustments. Results of operations for interim periods covered by this Quarterly Report on Form 10-Q may not necessarily be indicative of results of operations for the full fiscal year or any other interim period.
The unaudited condensed consolidated financial statements include the accounts of Peregrine and Avid. All intercompany accounts and transactions among the consolidated entities have been eliminated in the unaudited condensed consolidated financial statements.
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts, as well as disclosures of commitments and contingencies in the financial statements and accompanying notes. Actual results could differ materially from those estimates and assumptions. |

| Liquidity and Financial Condition |
Liquidity and Financial Condition
At October 31, 2016, we had $49,055,000 in cash and cash equivalents. We have expended substantial funds on the research and development of our product candidates, and funding the operations of Avid. As a result, we have historically experienced negative cash flows from operations since our inception and we expect negative cash flows from operations to continue until at least the fiscal year ending April 30, 2018 before we believe we can generate sufficient revenue from Avid’s contract manufacturing services to achieve profitability. Therefore, unless and until we are able to generate sufficient revenue from Avid’s contract manufacturing services or from the sale or licensing of our product candidates under development, we expect such losses to continue through at least the fiscal year ending April 30, 2018.
Our ability to continue to fund our operations is highly dependent on the amount of cash and cash equivalents on hand combined with our ability to raise additional capital to support our future operations through one or more methods, including but not limited to, (i) raising additional capital in the equity markets, (ii) generating additional revenue from Avid, or (iii) licensing or partnering our product candidates in development.
Historically, we have funded a significant portion of our operations through the issuance of equity. During the six months ended October 31, 2016, we raised $5,966,000 in aggregate gross proceeds from the sale of shares of our common stock and raised an additional $1,634,000 in aggregate gross proceeds from the sale of shares of our 10.5% Series E Convertible Preferred Stock (the “Series E Preferred Stock”) (Note 6). Subsequent to October 31, 2016 and through December 12, 2016, we raised an additional $1,670,000 in aggregate gross proceeds from the sale of shares of our common stock (Note 11). As of December 12, 2016, $105,345,000 remained available to us under our two effective shelf registration statements, which allows us from time to time to offer and sell shares of our common stock or Series E Preferred Stock, in one or more offerings, either individually or in combination.
Our ability to raise additional capital in the equity markets to fund our obligations in future periods is dependent on a number of factors, including, but not limited to, the market demand for our common stock or Series E Preferred Stock. The market demand or liquidity of our common stock and/or Series E Preferred Stock is subject to a number of risks and uncertainties, including but not limited to, negative economic conditions, adverse market conditions, adverse financial results, and negative research and development results. Furthermore, our ability to raise additional capital in the equity markets has been significantly impacted by the decline in the market price of our common stock following our announcement in February 2016 that we were discontinuing the Phase III SUNRISE trial. As a result, we have experienced a substantial decline in the amount of additional capital that we have been able to raise from the sale of shares of our common stock as compared to recent fiscal years. If the market price of our common stock does not improve significantly, we may not be able to rely on the sale of shares of our common stock to fund our operations to the extent we have in prior years. If we are unable to either (i) raise sufficient capital in the equity markets, (ii) generate additional revenue from Avid, or (iii) license or partner our products in development, or any combination thereof, we may need to delay, scale back, or eliminate some or all our research and development efforts, or restructure our operations, which may include delaying the planned expansion of our contract manufacturing business. In addition, even if we are able to raise additional capital, it may not be at a price or on terms that are favorable to us. |

Cash and Cash Equivalents
We consider all short-term investments readily convertible to cash with an initial maturity of three months or less to be cash equivalents. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Restricted Cash |
Restricted Cash
Under the terms of two separate operating leases related to our facilities, we are required to maintain, as collateral, letters of credit during the terms of such leases. At October 31, 2016 and April 30, 2016, we had restricted cash of $600,000, in aggregate, under these letters of credit. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Concentrations of Credit Risk and Customer Base |
Concentrations of Credit Risk and Customer Base
Financial instruments that potentially subject us to a significant concentration of credit risk consist of cash and cash equivalents, restricted cash and trade receivables. We maintain our cash and restricted cash balances primarily with one major commercial bank and our deposits held with the bank exceed the amount of government insurance limits provided on our deposits. We are exposed to credit risk in the event of default by the major commercial bank holding our cash and restricted cash balances to the extent of the cash and restricted cash amounts recorded on the accompanying interim unaudited condensed consolidated balance sheet.
Our trade receivables from amounts billed for contract manufacturing services provided by Avid have historically been derived from a small customer base. Most contracts require up-front payments and installment payments during the service period. We perform periodic evaluations of the financial condition of our customers and generally do not require collateral, but we can terminate any contract if a material default occurs. At October 31, 2016 and April 30, 2016, over 98% of our trade receivables were due from four customers.
In addition, contract manufacturing revenue generated by Avid has historically been derived from a small customer base (Note 9). These customers typically do not enter into long-term contracts because their need for drug supply depends on a variety of factors, including the drug’s stage of development, their financial resources, and, with respect to commercial drugs, demand for the drug in the market. Our future results of operations could be adversely affected if revenue from any one of our primary customers is significantly reduced or eliminated. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Revenue Recognition |
Revenue Recognition
We currently derive revenue from our contract manufacturing services provided by Avid. We recognize revenue in accordance with the authoritative guidance for revenue recognition when all of the following criteria are met: (i) persuasive evidence of an arrangement exists, (ii) delivery (or passage of title) has occurred or services have been rendered, (iii) the seller’s price to the buyer is fixed or determinable, and (iv) collectability is reasonably assured. We also comply with the authoritative guidance for revenue recognition regarding arrangements with multiple elements.
Revenue arrangements with multiple elements are divided into separate units of accounting if certain criteria are met, including whether the delivered element has stand-alone value to the customer or licensing partner. When deliverables are separable, consideration received is allocated among the separate units based on their respective fair values, and the applicable revenue recognition criteria are applied to each of the separate units, which may require the use of significant judgement. Deliverables are considered separate units of accounting if (1) the delivered item(s) has value to the customer on a stand-alone basis and (2) the arrangement includes a general right of return relative to the delivered item(s), delivery or performance of the undelivered item(s) is considered probable and substantially in our control.
Arrangement consideration is allocated at the inception of the agreement to all identified units of accounting based on their relative selling price. The relative selling price for each deliverable is determined using vendor specific objective evidence (“VSOE”) of selling price or third-party evidence of selling price if VSOE does not exist. If neither VSOE nor third-party evidence of selling price exists, we use our best estimate of the selling price for the deliverable. The amount of allocable arrangement consideration is limited to amounts that are fixed or determinable. The consideration received is allocated among the separate units of accounting, and the applicable revenue recognition criteria are applied to each of the separate units. Changes in the allocation of the sales price between delivered and undelivered elements can impact revenue recognition but do not change the total revenue recognized under any agreement.
Contract Manufacturing Revenue
Revenue associated with contract manufacturing services provided by Avid is recognized when all four of the aforementioned revenue recognition criteria have been met. For arrangements that include multiple elements, we follow the authoritative guidance for revenue recognition regarding arrangements with multiple deliverables, as described above.
On occasion, we receive requests from customers to hold product manufactured by Avid on a “bill-and-hold” basis. Revenue is recognized for such “bill-and-hold” arrangements in accordance with the authoritative guidance, which requires, among other things, the existence of a valid business purpose for the arrangement; the “bill-and-hold” arrangement is at the request of the customer; title and risk of ownership must pass to the customer; the product is complete and ready for shipment; a fixed delivery date that is reasonable and consistent with the customer’s business practices; the product has been separated from our inventory; and no further performance obligations by us exist.
In addition, we also follow the authoritative guidance when reporting revenue as gross when we act as a principal versus reporting revenue as net when we act as an agent. For transactions in which we act as a principal, have discretion to choose suppliers, bear credit and inventory risk and perform a substantive part of the services, revenue is recorded at the gross amount billed to a customer and costs associated with these reimbursements are reflected as a component of cost of sales for contract manufacturing services.
Any amounts received prior to satisfying our revenue recognition criteria are recorded as deferred revenue or customer deposits in the accompanying unaudited condensed consolidated financial statements. We also record a provision for estimated contract losses, if any, in the period in which they are determined. |

| Impairment |
Impairment
Long-lived assets are reviewed for impairment in accordance with authoritative guidance for impairment or disposal of long-lived assets. Long-lived assets are reviewed for events or changes in circumstances, which indicate that their carrying value may not be recoverable. Long-lived assets are reported at the lower of carrying amount or fair value less cost to sell. For the six months ended October 31, 2016 and 2015, there was no impairment of the value of our long-lived assets. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Fair Value Measurements |
Fair Value Measurements
Fair value is defined as 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 guidance prioritizes the inputs used in measuring fair value into the following hierarchy:
As of October 31, 2016 and April 30, 2016, we do not have any Level 2 or Level 3 financial assets or liabilities and our cash equivalents, which are primarily invested in money market funds with one major commercial bank, are carried at fair value based on quoted market prices for identical securities (Level 1 input). |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Customer Deposits |
Customer Deposits
Customer deposits primarily represent advance billings and/or payments received from Avid’s third-party customers prior to the initiation of contract manufacturing services. |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Research and Development Expenses |
Research and Development Expenses
Research and development expenses primarily include (i) payroll and related costs, including share-based compensation associated with research and development personnel, (ii) costs related to clinical trials and preclinical testing of our technologies under development, (iii) costs to develop and manufacture the product candidates, including raw materials and supplies, product testing, depreciation, and facility related expenses, (iv) expenses for research services provided by universities and contract laboratories, including sponsored research funding, and (v) other research and development expenses. Research and development expenses are charged to expense as incurred when these expenditures relate to our research and development efforts and have no alternative future uses.
Clinical trial costs are a significant component of our research and development expenses. We have a history of contracting with third parties that perform various clinical trial activities on our behalf in the ongoing development of our product candidates. The financial terms of these contracts are subject to negotiations and may vary from contract to contract and may result in uneven payment flow. Expenses related to clinical trials are accrued based on our estimates and/or representations from third parties (including clinical research organizations) regarding services performed. If the contracted amounts are modified (for instance, as a result of changes in the clinical trial protocol or scope of work to be performed), we modify our accruals accordingly on a prospective basis. Revisions in the scope of a contract are charged to expense in the period in which the facts that give rise to the revision become reasonably certain. There were no material adjustments for a change in estimate to research and development expenses in the accompanying unaudited condensed consolidated financial statements for the three and six months ended October 31, 2016 and 2015.
Under certain research and development agreements, we are obligated to make certain advance payments, including nonrefundable amounts, for goods or services that will be used or rendered for future research and development activities and are deferred and capitalized as prepaid research and development expenses. These advance payments are recognized as an expense in the period the related goods are delivered or the related services are performed. We assess our prepaid research and development expenses for impairment when events or changes in circumstances indicate that the carrying amount of the prepaid expense may not be recoverable or provide future economic benefit.
In addition, under certain in-licensing agreements associated with the research and development of our product candidates, we are obligated to pay certain milestone payments based on potential clinical development and regulatory milestones. These milestone payments have no alternative future uses (in other research and development projects or otherwise) and therefore have no separate economic values and are expensed as research and development costs at the time the costs are incurred. We have no in-licensed product candidates that have alternative future uses in research and development projects or otherwise. |

| Share-based Compensation |
Share-based Compensation
We account for stock options and other share-based awards granted under our equity compensation plans in accordance with the authoritative guidance for share-based compensation. The estimated fair value of share-based payments to employees in exchange for services is measured at the grant date, using a fair value based method, such as a Black-Scholes option valuation model, and is recognized as expense on a straight-line basis over the requisite service periods. The fair value of modifications to share-based awards, if any, is generally estimated using a Black-Scholes option valuation model, unless a lattice model is required. Share-based compensation expense recognized during the period is based on the value of the portion of the share-based payment that is ultimately expected to vest during the period. As of October 31, 2016, there were no outstanding share-based awards with market or performance conditions.
Periodically, we grant stock options and other share-based awards to non-employee consultants, which we account for in accordance with the authoritative guidance for share-based compensation. The cost of non-employee services received in exchange for share-based awards are measured based on either the fair value of the consideration received or the fair value of the share-based award issued, whichever is more reliably measurable. In addition, guidance requires share-based compensation related to unvested options and awards issued to non-employees to be recalculated at the end of each reporting period based upon the fair market value on that date until the share-based award has vested, and any cumulative catch-up adjustment to share-based compensation resulting from the re-measurement is recognized in the current period (Note 7). |

| Basic and Dilutive Net Loss Per Common Share |
Basic and Dilutive Net Loss Per Common Share
Basic net loss per common share is computed by dividing our net loss attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period excluding the dilutive effects of stock options, shares of common stock expected to be issued under our Employee Stock Purchase Plan (the “ESPP”), warrants, and Series E Preferred Stock outstanding during the period. Diluted net loss per common share is computed by dividing our net loss attributable to common stockholders by the sum of the weighted average number of shares of common stock outstanding during the period plus the potential dilutive effects of stock options, shares of common stock expected to be issued under our ESPP, warrants, and Series E Preferred Stock outstanding during the period. Net loss attributable to common stockholders represents our net loss plus Series E Preferred Stock accumulated dividends. Series E Preferred Stock accumulated dividends include dividends declared for the period (regardless of whether or not the dividends have been paid) and dividends accumulated for the period (regardless of whether or not the dividends have been declared).
The potential dilutive effect of stock options, shares of common stock expected to be issued under our ESPP, and warrants outstanding during the period are calculated in accordance with the treasury stock method, but are excluded if their effect is anti-dilutive. The potential dilutive effect of Series E Preferred Stock outstanding during the period was calculated using the if-converted method assuming the conversion of Series E Preferred Stock as of the earliest period reported or at the date of issuance, if later, but are excluded if their effect is anti-dilutive. However, because the impact of stock options, shares of common stock expected to be issued under our ESPP, warrants, and Series E Preferred Stock are anti-dilutive during periods of net loss, there was no difference between basic and diluted loss per common share amounts for the three and six months ended October 31, 2016 and 2015.
The calculation of weighted average diluted shares outstanding for the three and six-month periods ended October 31, 2016 and 2015 excludes the dilutive effect of the following weighted average outstanding stock options and shares of common stock expected to be issued under our ESPP as their impact are anti-dilutive during periods of net loss, resulting in an anti-dilutive effect:
The calculation of weighted average diluted shares outstanding for the three and six-month periods ended October 31, 2016 and 2015 also excludes the following weighted average outstanding stock options, warrants, and Series E Preferred Stock (assuming the if-converted method), as their exercise prices or conversion price were greater than the average market price of our common stock during the respective periods, resulting in an anti-dilutive effect:
Subsequent to October 31, 2016 and through December 12, 2016, we sold an aggregate of 5,376,255 shares of our common stock (Note 11), which are not included in the calculation of basic and dilutive net loss per common share for the three and six months ended October 31, 2016. |

| Pending Adoption of Recent Accounting Pronouncements |
Pending Adoption of Recent Accounting Pronouncements
In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606): Revenue from Contracts with Customers, which amends the guidance in former ASC 605, Revenue Recognition, which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most current revenue recognition guidance. ASU No. 2014-09 is based on the principle that revenue is recognized to depict the transfer of 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 ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. ASU No. 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period, and entities can transition to the standard either retrospectively or as a cumulative-effect adjustment as of the date of adoption. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which defers the effective date of ASU No. 2014-09 by one year, but permits entities to adopt one year earlier if they choose (i.e., the original effective date). As such, ASU No. 2014-09 will be effective for annual reporting periods ending after December 15, 2017, which will be our fiscal year 2019 beginning May 1, 2018. We are currently in the process of evaluating the impact of adoption of ASU No. 2014-09 on our consolidated financial statements and related disclosures, including what transition method will be elected.
In August 2014, the FASB issued ASU No. 2014-15, Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. ASU No. 2014-15 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. Substantial doubt about an entity’s ability to continue as a going concern exists when relevant conditions and events, considered in the aggregate, indicate that it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued (or available to be issued). ASU No. 2014-15 provides guidance to an organization’s management, with principles and definitions that are intended to reduce diversity in the timing and content of disclosures that are commonly provided by organizations in the financial statement footnotes. ASU No. 2014-15 is effective for annual reporting periods ending after December 15, 2016, which will be our fiscal year ending April 30, 2017, and to annual and interim periods thereafter. Early adoption is permitted. We have not yet determined the effect that the adoption of this guidance will have on the disclosures included in our consolidated financial statements as our analysis regarding our ability to continue as a going concern will be performed in conjunction with the preparation of our Annual Report on Form 10-K for the fiscal year ending April 30, 2017.
In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. ASU 2015-11 requires that for entities that measure inventory using the first-in, first-out method, inventory should be measured at the lower of cost and net realizable value. ASU 2015-11 defines net realizable value as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. ASU 2015-11 is effective for fiscal years beginning after December 15, 2016, which will be our fiscal year 2018 beginning May 1, 2017, and interim periods within those fiscal years. The amendments should be applied prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. We are currently in the process of evaluating the impact of adoption of ASU No. 2015-11 on our consolidated financial statements and related disclosures.
In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. Under existing standards, deferred taxes for each tax-paying jurisdiction are presented as a net current asset or liability and net long-term asset or liability. To simplify presentation, the new guidance will require that all deferred tax assets and liabilities, along with related valuation allowances, be classified as long-term on the balance sheet. As a result, each tax-paying jurisdiction will now only have one net long-term deferred tax asset or liability. The new guidance does not change the existing requirement that prohibits offsetting deferred tax liabilities from one jurisdiction against deferred tax assets of another jurisdiction. ASU No. 2015-17 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, which will be our fiscal year 2018 beginning May 1, 2017. We do not expect the adoption of ASU No. 2015-17 to have a material impact on our consolidated financial statements and related disclosures.
In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). ASU No. 2016-2 requires an entity to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU No. 2016-02 offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. ASU No. 2016-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, which will be our fiscal year 2020 beginning May 1, 2019. Early adoption is permitted. We are currently in the process of evaluating the impact of adoption of ASU No. 2016-02 on our consolidated financial statements and related disclosures.
In March 2016, FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718). ASU No. 2016-09 changes certain aspects of accounting for share-based payments to employees and involves several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Specifically, ASU No. 2016-09 requires that all income tax effects of share-based awards be recognized as income tax expense or benefit in the reporting period in which they occur. Additionally, ASU No. 2016-09 amends existing guidance to allow forfeitures of share-based awards to be recognized as they occur. Previous guidance required that share-based compensation expense include an estimate of forfeitures. ASU No. 2016-09 is effective for annual and interim periods beginning after December 15, 2016, which will be our fiscal year 2018 beginning May 1, 2017. Early adoption is permitted. We are currently evaluating the impact the adoption of ASU No. 2016-09 will have on our consolidated financial statements and related disclosures.
In November 2016, FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which addresses diversity in practice related to the classification and presentation of changes in restricted cash on the statement of cash flows. ASU No. 2016-18 will require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. ASU No. 2016-18 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, which will be our fiscal year 2019 beginning May 1, 2018. Early adoption is permitted. We are currently evaluating the impact the adoption of ASU No. 2016-18 will have on our consolidated financial statements and related disclosures. |
