Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization

1. ORGANIZATION

Advaxis, Inc. (“Advaxis” or the “Company”) is a clinical stage biotechnology company focused on the discovery, development and commercialization of proprietary Lm -LLO cancer immunotherapies. These immunotherapies are based on a platform technology that utilizes live attenuated Listeria monocytogenes (“Lm” or “Listeria”), bioengineered to secrete antigen/adjuvant fusion proteins. These Lm -LLO strains are believed to be a significant advancement in immunotherapy as they integrate multiple functions into a single immunotherapy as they access and direct antigen presenting cells to stimulate anti-tumor T-cell immunity, stimulate and activate the immune system with the equivalent of multiple adjuvants, and simultaneously reduce tumor protection in the tumor microenvironment to enable the T-cells to eliminate tumors.

ADXS-HPV is the Company’s lead Lm -LLO immunotherapy product candidate for the treatment of human papilloma virus (“HPV”) associated cancers. The Company completed a randomized Phase 2 study in 110 patients with recurrent cervical cancer that was shown to have a manageable safety profile, improved survival and objective tumor responses. In addition, the Gynecologic Oncology Group (“GOG”), now part of NRG Oncology, is conducting a Phase 2 open-label clinical study of ADXS-HPV in patients with persistent or recurrent cervical cancer with documented disease progression. The study, known as GOG 0265, has successfully completed its first stage and has met the predetermined safety and efficacy criteria required to proceed into the second stage of patient recruitment which is now enrolling. The Company plans to advance this immunotherapy into a registrational clinical trial for the treatment of women with high-risk locally advanced cervical cancer.

ADXS-HPV has received United States Food and Drug Administration (“FDA”) orphan drug designation for three HPV-associated cancers: cervical, head and neck, and anal cancer, and is being evaluated in Company-sponsored trials executed under an Investigational New Drug (“IND”) include the following: i) a Phase 1/2 clinical trial alone and in combination with MedImmune’s investigational anti-PD-L1 immune checkpoint inhibitor, MEDI4736, in patients with previously treated metastatic HPV-associated cervical cancer and HPV-associated head and neck cancer; ii) a Phase 2 multi-center, open-label study alone and in combination with Incyte’s investigational oral indoleamine 2,3-dioxygenase 1 (IDO1) inhibitor, epacadostat (INCB24360) in patients with Stage I-IIa HPV-associated cervical cancer; iii) a Phase 1/2 study evaluating higher doses and repeat cycles of ADXS-HPV in patients with recurrent cervical cancer; and, iv) a Phase 2 study in collaboration with and funded by Global BioPharma Inc. (“GBP”), under a development and commercialization license agreement applicable to Asia, of ADXS-HPV in HPV-associated non-small cell lung cancer. In addition to the Company-sponsored trials, ADXS-HPV is also beging evaluated in three ongoing investigator-initiated clinical trials as follows: locally advanced cervical cancer (cooperative group sponsor), head and neck cancer, and anal cancer.

ADXS-PSA is the Company’s Lm -LLO immunotherapy product candidate designed to target the Prostate Specific Antigen (“PSA”) associated with prostate cancer. The FDA has cleared the Company’s IND application and the Company has initiated a Phase 1/2 clinical trial alone and in combination with KEYTRUDA® (pembrolizumab), Merck’s humanized monoclonal antibody against PD-1, in patients with previously treated metastatic castration-resistant prostate cancer.

ADXS-HER2 is the Company’s Lm -LLO immunotherapy product candidate designed for the treatment of Human Epidermal Growth Factor Receptor 2 (“HER2”) expressing cancers, including human and canine osteosarcoma, breast, gastric and other cancers. The FDA has cleared the Company’s IND application and is in the process of initiating a Phase 1b clinical trial in patients with metastatic HER2 expressing solid tumors. The Company received orphan drug designation for ADXS-HER2 in osteosarcoma. Clinical research with ADXS-HER2 in canine osteosarcoma is being developed by the Company’s pet therapeutic partner, Aratana Therapeutics Inc. (“Aratana”), who holds exclusive rights to develop and commercialize ADXS-HER2 and three other Lm -LLO immunotherapies for pet health applications. Aratana has announced that a product license application for use of ADXS-HER2 in the treatment of canine osteosarcoma has been filed with the United States Department of Agriculture (“USDA”). Aratana received communication from the USDA in March 2015 that the efficacy data previously submitted for product license for AT-014 (ADXS-HER2), the cancer immunotherapy for canine osteosarcoma, licensed from the Company was accepted to provide a reasonable expectation of efficacy to support conditional licensure. While Aratana needs to complete additional steps, including in the areas of manufacturing and safety, Aratana anticipates that AT-014 could receive conditional licensure from the USDA in 2016.

Since inception in 2002, the Company has focused its development efforts on understanding its platform technology and establishing a drug development pipeline that incorporates this technology into therapeutic cancer immunotherapies, currently those targeting HPV-associated cancer (cervical cancer, head and neck cancer and anal cancer), prostate cancer, and HER2 expressing cancers. Although no immunotherapies have been commercialized to date, research and development and investment continues to be placed behind the advancement of this technology. Pipeline development and the further exploration of the technology for advancement entails risk and expense. The Company anticipates that its ongoing operational costs will increase significantly as it continues conducting and expanding its clinical development program. Further, over twenty distinct additional constructs leveraging certain antigens highly expressed in multiple tumor types, developed directly by the Company and through strategic collaborations with recognized centers of excellence, are in various stages of development. Impending priority research advances include, but are not limited to, constructs targeting pan tumor antigens and tumor stromal targets.

Liquidity and Financial Condition

The Company’s products are being developed and have not generated significant revenues. As a result, the Company has suffered recurring losses. These losses are expected to continue for an extended period of time. On December 19, 2014, the Company priced a registered direct offering of 3,940,801 shares of its Common Stock (“Common Stock”). The transaction closed on December 22, 2014, and the Company received net proceeds of approximately $15.8 million from the offering. In addition, on February 18, 2015, the Company priced an additional registered direct offering of 3,068,095 shares of its Common Stock. The transaction closed on February 19, 2015, and the Company received net proceeds of approximately $22.3 million from the offering. The shares in each offering were sold under a Registration Statement (No. 333-194009) on Form S-3, filed by the Company with the United States Securities and Exchange Commission (“SEC”). On May 5, 2015, the Company closed on an underwritten public offering of 2,800,000 shares of Common Stock at a public offering price of $19.00 per share. The gross proceeds from the public offering were $53.2 million. Excluding any underwriting commissions, the estimated expenses incurred by the Company in connection with its issuance and distribution of the shares of common stock were $340,000. On May 20, 2015, the Company closed the Underwriters’ overallotment option to purchase 420,000 shares of its Common Stock at a public offering price of $19.00 per share, resulting in additional gross proceeds of $8.0 million.

The Company believes its current cash position is sufficient to fund its business plan approximately through calendar 2017. The estimate is based on assumptions that may prove to be wrong, and the Company could use available capital resources sooner than currently expected. Because of the numerous risks and uncertainties associated with the development and commercialization of its product candidates, the Company is unable to estimate the amount of increased capital outlays and operating expenses associated with completing the development of its current product candidates.

The Company recognizes it may need to raise additional capital over and above the amount raised during December 2014, February 2015 and May 2015 in order to continue to execute its business plan. Subsequent to April 30, 2015, the Company intends to continue to raise additional funds through sales of equity securities. There is no assurance that additional financing will be available when needed or that management will be able to obtain financing on terms acceptable to the Company or whether the Company will become profitable and generate positive operating cash flow. If the Company is unable to raise sufficient additional funds, it will have to scale back its business plan.

Summary of Significant Accounting Policies and Basis of Presentation

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND BASIS OF PRESENTATION

Basis of Presentation - Unaudited Interim Financial Information

The accompanying unaudited interim condensed financial statements and related notes have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information, and in accordance with the rules and regulations of the SEC with respect to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The unaudited interim financial statements furnished reflect all adjustments (consisting of normal recurring accruals) which are, in the opinion of management, necessary to represent a fair statement of the results for the interim periods presented. Interim results are not necessarily indicative of the results for the full year. These unaudited interim financial statements should be read in conjunction with the financial statements of the Company for the year ended October 31, 2014 and notes thereto contained in the Company’s annual report on Form 10-K for the year ended October 31, 2014, as filed with the SEC on January 6, 2015.

Revenue Recognition

The Company is expected to derive the majority of its revenue from patent licensing. In general, these revenue arrangements provide for the payment of contractually determined fees in consideration for the grant of certain intellectual property rights for patented technologies owned or controlled by the Company. The intellectual property rights granted may be perpetual in nature, or upon the final milestones being met, or can be granted for a defined, relatively short period of time, with the licensee possessing the right to renew the agreement at the end of each contractual term for an additional minimum upfront payment. The Company recognizes licensing fees when there is persuasive evidence of a licensing arrangement, fees are fixed or determinable, delivery has occurred and collectability is reasonably assured.

An allowance for doubtful accounts is established based on the Company’s best estimate of the amount of probable credit losses in the Company’s existing license fee receivables, using historical experience. The Company reviews its allowance for doubtful accounts periodically. Past due accounts are reviewed individually for collectability.

Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. To date, this is yet to occur.

If product development is successful, the Company will recognize revenue from royalties based on licensees’ sales of its products or products using its technologies. Royalties are recognized as earned in accordance with the contract terms when royalties from licensees can be reasonably estimated and collectability is reasonably assured. If royalties cannot be reasonably estimated or collectability of a royalty amount is not reasonably assured, royalties are recognized as revenue when the cash is received.

The Company recognizes revenue from milestone payments received under collaboration agreements when earned, provided that the milestone event is substantive, its achievability was not reasonably assured at the inception of the agreement, the Company has no further performance obligations relating to the event and collection is reasonably assured. If these criteria are not met, the Company recognizes milestone payments ratably over the remaining period of the Company’s performance obligations under the collaboration agreement. All such recognized revenues are included in collaborative licensing and development revenue in the Company’s consolidated statements of operations.

Estimates

The preparation of financial statements in accordance with GAAP involves the use of estimates and assumptions that affect the recorded amounts of assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results may differ substantially from these estimates. Significant estimates include the fair value and recoverability of the carrying value of intangible assets (patents and licenses), the fair value of options, the fair value of embedded conversion features, warrants and related disclosure of contingent assets and liabilities. On an on-going basis, the Company evaluates its estimates, based on historical experience and on various other assumptions that it believes to be reasonable under the circumstances. Actual results may differ from estimates.

Concentration of Credit Risk

The Company maintains its cash in bank deposit accounts (checking) that at times exceed federally insured limits. Approximately $45.7 million is subject to credit risk at April 30, 2015. However, these cash balances are maintained at creditworthy financial institutions. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk.

Fair Value of Financial Instruments

The carrying amounts of financial instruments, including cash, accounts payable and accrued expenses approximated fair value as of the balance sheet date presented, because of the relatively short maturity dates on these instruments. The carrying amounts of the financing arrangements issued approximate fair value as of the balance sheet date presented, because interest rates on these instruments approximate market interest rates after consideration of stated interest rates, anti-dilution protection and associated warrants.

Net Loss per Share

Basic net income or loss per common share is computed by dividing net income or loss available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share give effect to dilutive options, warrants, convertible debt and other potential Common Stock outstanding during the period. In the case of a net loss the impact of the potential Common Stock resulting from warrants, outstanding stock options and convertible debt are not included in the computation of diluted loss per share, as the effect would be anti-dilutive. In the case of net income the impact of the potential Common Stock resulting from these instruments that have intrinsic value are included in the diluted earnings per share. The table sets forth the number of potential shares of Common Stock that have been excluded from diluted net loss per share.

	As of April 30,
	2015		2014
Warrants		3,862,273		4,541,454
Stock Options		798,357		491,923

Convertible Debt (using the if-converted method)		1,576		3,354
Total		4,662,206		5,243,720

Stock Based Compensation

The Company has an equity plan which allows for the granting of stock options to its employees, directors and consultants for a fixed number of shares with an exercise price equal to the fair value of the shares at date of grant. The Company measures the cost of services received in exchange for an award of equity instruments based on the fair value of the award. For employees and directors, the fair value of the award is measured on the grant date and for non-employees, the fair value of the award is generally measured based on contractual terms. The fair value amount is then recognized over the requisite service period, usually the vesting period, in both research and development expenses and general and administrative expenses on the statement of operations depending on the nature of the services provided by the employees or consultants.

The process of estimating the fair value of stock-based compensation awards and recognizing stock-based compensation cost over their requisite service period involves significant assumptions and judgments. The Company estimates the fair value of stock option awards on the date of grant using the Black Scholes Model (“BSM”) for the remaining awards, which requires that the Company makes certain assumptions regarding: (i) the expected volatility in the market price of its Common Stock; (ii) dividend yield; (iii) risk-free interest rates; and (iv) the period of time employees are expected to hold the award prior to exercise (referred to as the expected holding period). As a result, if the Company revises its assumptions and estimates, stock-based compensation expense could change materially for future grants.

The Company accounts for stock-based compensation using fair value recognition and records stock-based compensation as a charge to earnings net of the estimated impact of forfeited awards. As such, the Company recognizes stock-based compensation cost only for those stock-based awards that are estimated to ultimately vest over their requisite service period, based on the vesting provisions of the individual grants.

Recent Accounting Pronouncements

In January 2015, the FASB issued ASU 2015-01, Income Statement —Extraordinary and Unusual Items. The objective of this Update is to simplify the income statement presentation requirements in Subtopic 225-20 by eliminating the concept of extraordinary items. Extraordinary items are events and transactions that are distinguished by their unusual nature and by the infrequency of their occurrence. Eliminating the extraordinary classification simplifies income statement presentation by altogether removing the concept of extraordinary items from consideration. This Accounting Standards Update is the final version of Proposed Accounting Standards Update 2014-220—Income Statement—Extraordinary Items (Subtopic 225-20), which has been deleted. The amendments in this Update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. This Update is not expected to have a material impact on the Company’s financial statements.

Management does not believe that any other recently issued, but not yet effective accounting pronouncements, if adopted, would have a material impact on the accompanying condensed financial statements.

	Warrants			Exercise Price
Outstanding Warrants at October 31, 2014:		4,158,092		$	5.42
Issued		2,361		$	7.20
Exercised *		(169,121	)		4.12
Expired		(129,059	)	$	10.46
Outstanding Warrants at April 30, 2015		3,862,273		$	5.12

* Includes the cashless exercise of 120,634 warrants that resulted in the issuance of 99,400 shares of common stock.

At April 30, 2015, the Company had approximately 3.83 million of its total 3.86 million outstanding warrants classified as equity (equity warrants). At October 31, 2014, the Company had approximately 4.1 million of its total 4.2 million outstanding warrants classified as equity (equity warrants). At issuance, equity warrants are recorded at their relative fair values, using the Relative Fair Value Method, in the shareholders’ equity section of the balance sheet. The equity warrants can only be settled through the issuance of shares and are not subject to anti-dilution provisions.

Warrant Liability/Embedded Derivative Liability

Warrant Liability

At April 30, 2015, the Company had approximately 29,000 of its total approximately 3.86 million outstanding warrants classified as liability warrants (liability warrants). As of October 31, 2014, the Company had approximately 123,000 of its total approximately 4.2 million total warrants classified as liabilities (liability warrants). All of these liability warrants at April 30, 2015 and October 31, 2014 were outstanding. The Company utilizes the BSM to calculate the fair value of these warrants at issuance and at each subsequent reporting date. For those warrants with exercise price reset features (anti-dilution provisions), the Company computes multiple valuations, each quarter, using an adjusted BSM, to account for the various possibilities that could occur due to changes in the inputs to the BSM as a result of contractually-obligated changes (for example, changes in strike price to account for down-round provisions). The Company effectively weights each calculation based on the likelihood of occurrence to determine the value of the warrants at the reporting date. At April 30, 2015, none of the 29,000 liability warrants are subject to weighted-average anti-dilution provisions. At October 31, 2014, approximately 60,000 of the 123,000 liability warrants are subject to weighted-average anti-dilution provisions. A certain number of liability warrants contain a cash settlement provision in the event of a fundamental transaction (as defined in the Common Stock purchase warrant). Any changes in the fair value of the warrant liability (i.e. - the total fair value of all outstanding liability warrants at the balance sheet date) between reporting periods will be reported on the statement of operations.

At April 30, 2015 and October 31, 2014, the fair value of the warrant liability was approximately $328,000 and $32,000, respectively. For the three and six months ended April 30, 2015, the Company reported losses of approximately $23,000 and $287,000, respectively, due to changes in the fair value of the warrant liability. For the three and six months ended April 30, 2014, the Company reported gains of approximately $274,000 and $406,000, respectively, due to changes in the fair value of the warrant liability. In fair valuing the warrant liability, at April 30, 2015 and October 31, 2014, the Company used the following inputs in its BSM:

		4/30/2015			10/31/2014

Exercise Price:	$	5.63-10.63		$	2.76-21.25

Stock Price	$	16.81		$	3.18

Expected term:		184-825 days			4-1006 days

Volatility %		107.86%-118.38	%		55.41%-129.38	%

Risk Free Rate:		.06%-.58	%		.01%-1.62	%

Exercise of Warrants

During the six months ended April 30, 2015, warrants to purchase 169,121 shares of common stock were exercised, which resulted in cash proceeds of $239,593.

Expiration of Warrants

During the six months ended April 30, 2015, the Company had 62,430 warrants with anti-dilution provisions, and 66,629 warrants with no such anti-dilution provisions, expire unexercised.

Warrants with anti-dilution provisions

Some of the Company’s warrants contained anti-dilution provisions originally set at $25.00 with a term of five years. As of April 30, 2015, all of these warrants had expired. As of October 31, 2014, these warrants had an exercise price of approximately $7.71. If the Company issues any Common Stock, except for exempt issuances as defined in the warrant agreement, for consideration less than the exercise price then the exercise price and the amount of warrant shares available would be adjusted to a new price and amount of shares per the “weighted average” formula included in the warrant agreement. For the three and six months ended April 30, 2015, this anti-dilution provision required the Company to issue approximately 2,400 additional warrant shares; and the exercise price to be lowered to $7.20.

For those warrants with exercise price reset features (anti-dilution provisions), the Company computed multiple valuations, each quarter, using an adjusted BSM, to account for the various possibilities that could occur due to changes in the inputs to the BSM as a result of contractually-obligated changes (for example, changes in strike price to account for down-round provisions). The Company utilized different exercise prices of $7.20 and $6.00, weighting the possibility of warrants being exercised at $7.20 between 40% and 50% and warrants being exercised at $6.00 between 60% and 50%.

As of April 30, 2015, there were outstanding warrants to purchase 3,862,273 shares of the Company’s Common Stock with exercise prices ranging from $2.76 to $18.75 per share.

Legal Proceedings

Iliad Research and Trading

On March 24, 2014, Iliad Research and Trading, L.P. (“Iliad”) filed a complaint (the “Complaint”) against the Company in the Third Judicial District Court of Salt Lake County, Utah, purporting to assert claims for breach of express and implied contract. Specifically, Iliad alleged that the Company granted a participation right to Tonaquint, Inc. (“Tonaquint”) in a securities purchase agreement between Tonaquint and the Company, dated as of December 13, 2012 (the “Purchase Agreement”), pursuant to which Tonaquint was entitled to participate in any transaction that the Company structured in accordance with Section 3(a)(9) or Section 3(a)(10) of the Securities Act of 1933, as amended. Iliad further alleged that the settlement that the Company entered into with Ironridge Global IV, Ltd. (“Ironridge”), pursuant to which the Company issued certain shares of its Common Stock to Ironridge in reliance on the Section 3(a)(10) exemption, occurred without adequate notice for Tonaquint to exercise its participation right. In addition, Iliad alleged that it acquired all of Tonaquint’s rights under the Purchase Agreement in April 2013.

On June 2, 2014, Iliad filed an amended complaint (the “Amended Complaint”), which purported to add claims against the Company under the federal and Utah securities laws and for common law fraud. On June 30, 2014, the Company removed the action to the United States District Court for the District of Utah. On August 1, 2014, after the Court issued its Order Granting Stipulated Motion for Leave to File Second Amended Complaint, Iliad filed a Second Amended Complaint (the “SAC”), which purported to add a sixth claim for conversion. On August 22, 2014, the Company filed papers in support of its motion to dismiss the SAC in its entirety. On November 24, 2014, the Court filed an order dismissing the conversion claim but denying the remainder of the motion to dismiss.

Meanwhile, on September 22, 2014, Iliad filed papers in support of its motion for partial summary judgment of liability on the express contact claim. On December 5, 2014, Advaxis filed papers in opposition to the motion for partial summary judgment and in support of its separate motion under Rule 56(d) to deny partial summary judgment and for allowance of discovery. On December 8, 2014, Advaxis filed its answer to the SAC and a counterclaim (the “Counterclaim”), alleging that Iliad – by purporting to have surreptitiously preserved its claim for breach of Tonaquint’s alleged right to participate in the Ironridge transaction – had fraudulently induced Advaxis to enter into the parties’ post-assignment Exchange and Settlement Agreement and, in the alternative, had breached the covenant of good faith and fair dealing implied therein. On January 23, 2015, Iliad filed its Reply to Counterclaim (rather than attempting to move to dismiss Advaxis’s Counterclaim). On May 4, 2015, the Court filed its Memorandum Decision and Order, which grants the partial motion for summary judgement and denies the Rule 56(d) motion, finding that Advaxis materially breached the Purchase Agreement.

On May 28, 2015, following a Scheduling Conference, the Court set the following case deadlines: end of discovery (January 15, 2016); dispositive and expert motions (February 12, 2016); Proposed Pretrial Order (March 23, 2016); and Final Pretrial Conference (March 25, 2016).

Iliad seeks “damages in an amount to be determined at trial” (though the common law fraud damages alone are alleged to be “greater than $300,000”) plus interest, attorneys’ fees and costs. Iliad has also asked for punitive damages in connection with its claims under the Utah Securities Act (equal to three times its actual damages), and common law fraud. The Company intends to continue to defend itself vigorously.

Numoda

On June 19, 2009, the Company entered into a master agreement and on July 8, 2009, the Company entered into a Project Agreement with Numoda Corporation (“Numoda”), to oversee Phase 2 clinical activity with ADXS-HPV for the treatment of invasive cervical cancer and CIN.

On October 1, 2014, the Company filed a Complaint against Numoda seeking a declaratory judgment that, with its tender to Numoda of a check for $68,884.00, the Company had fully performed the parties’ Project Agreement and that Numoda was not entitled to interest, costs or attorneys’ fees thereunder or otherwise. On January 9, 2015, Numoda filed papers in support of its motion to dismiss the Complaint. On January 23, 2015, the Company filed an Amended Complaint against Numoda seeking an order directing Numoda to specifically perform its obligation to deliver to Advaxis all materials, information and other data generated under the parties’ Project Agreement. On February 25, 2015, the Court endorsed a letter from Numoda’s counsel withdrawing its motion to dismiss the Complaint in light of the Amended Complaint. On February 20, 2015, Numoda filed an Answer denying liability and asserting a number of affirmative defenses. With Court approval of a stipulation of the parties, the Preliminary Conference was adjourned from May 28, 2015 until August 13, 2015.

The Company is from time to time involved in legal proceedings in the ordinary course of its business. The Company does not believe that any of these claims and proceedings against us is likely to have, individually or in the aggregate, a material adverse effect on its financial condition or results of operations.

Description of Property

The Company’s corporate offices are currently located at 305 College Road East, Princeton, New Jersey 08540. On April 1, 2011, the Company entered into a sublease agreement for such office, which agreement has a termination date of November 29, 2015. In May 2015, the Company entered into a direct lease for an expansion area, as well as a direct lease for the existing office, lab and vivarium space upon the expiration of the sublease agreement, which is approximately 20,000 square foot of space in Princeton, NJ. The Company plans to continue to rent necessary offices and laboratories to support its business.

Fair Value Disclosures [Abstract]

Fair Value

11. FAIR VALUE

The authoritative guidance for fair value measurements defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or the most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact, and (iv) willing to transact. The guidance describes a fair value hierarchy based on the levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which are the following:

● Level 1 — Quoted prices in active markets for identical assets or liabilities

● Level 2— Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or corroborated by observable market data or 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 value of the assets or liabilities

The following table provides the liabilities carried at fair value measured on a recurring basis as of April 30, 2015 and October 31, 2014:

April 30, 2015	Level 1		Level 2	Level 3		Total
