2.Summary of Significant Accounting Policies

These unaudited condensed consolidated interim financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K, as amended on Form 10-K/A for the year ended June 30, 2017. The Company adheres to the same accounting policies in preparation of its interim financial statements.

Principles of Consolidation and Presentation

The condensed consolidated financial statements include the accounts of Immunomedics and its subsidiaries. Noncontrolling interests in consolidated subsidiaries in the condensed consolidated balance sheets represent minority stockholders’ proportionate share of the deficit in such subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Financial Instruments

The carrying amounts of cash and cash equivalents, other current assets and current liabilities approximate fair value due to the short-term maturity of these instruments. The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents.

Marketable Securities

Marketable securities, all of which are available-for-sale, consist of corporate debt securities, U.S. bonds, U.S. sponsored agencies and municipal bonds. Corporate debt securities include Eurodollar issues of U.S. corporations, and U.S. dollar denominated issues of foreign corporations. Marketable securities are carried at fair value, with unrealized gains and losses, net of related income taxes, reported as accumulated other comprehensive loss, except for losses from impairments which are determined to be other-than-temporary. Realized gains and losses, and declines in value judged to be other-than-temporary on available-for-sale securities are included in the determination of net loss and are included in interest and other income (net), at which time the average cost basis of these securities are adjusted to fair value. Fair values are based on quoted market prices at the reporting date. Interest and dividends on available-for-sale securities are included in interest and other income (net).

Inventory

Inventory, which consists of the raw materials, work-in-process and finished product of LeukoScan®, is stated at the lower of cost and net realizable value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The Company will capitalize inventory costs associated with the Company’s product, IMMU-132, after regulatory approval when, based on management’s judgment, future commercialization is considered probable and the future economic benefit is expected to the realized; otherwise, such costs are expensed as research and development. In addition, the Company’s product is subject to strict quality control and monitoring which the Company performs throughout the manufacturing process. If certain batches or units of product no longer meet quality specification or become obsolete due to expiration, the Company records a charge to cost of sales sold to write down such unmarketable inventory to zero.

Revenue Recognition

The Company has accounted for revenue arrangements that include multiple deliverables as a separate unit of accounting if both of the following criteria are met: a) the delivered item has value to the customer on a standalone basis, and b) if the right of return exists, delivery of the undelivered items is considered probable and substantially in the control of the vendor. If these criteria are not met, the revenue elements must be considered a single unit of accounting for purposes of revenue recognition. The Company allocates revenue consideration, excluding contingent consideration, based on the relative selling prices of the separate units of accounting contained within an arrangement containing multiple deliverables. Relative selling prices are determined using vendor specific objective evidence, if it exists; otherwise third-party evidence or the Company’s best estimate of selling price is used for each deliverable.

Payments received under contracts to fund certain research activities are recognized as revenue in the period in which the research activities are performed. Payments received in advance that are related to future performance are deferred and recognized as revenue when the research projects are performed. Upfront nonrefundable fees associated with license and development agreements where the Company has continuing involvement in the agreement are recorded as deferred revenue and recognized over the estimated service period. The Company estimates the period of continuing involvement based on the best evidential matter available at each reporting period. If the estimated service period is subsequently modified, the period over which the upfront fee is recognized is modified accordingly on a prospective basis.

In order to determine the revenue recognition for contingent milestones, the Company evaluates the contingent milestones using the criteria as provided by the Financial Accounting Standards Boards (“FASB”) guidance on the milestone method of revenue recognition, as explained in ASU 2010-17, “Milestone Method of Revenue Recognition,” at the inception of a collaboration agreement. The criteria requires that (i) the Company determines if the milestone is commensurate with either its performance to achieve the milestone or the enhancement of value resulting from the Company’s activities to achieve the milestone, (ii) the milestone be related to past performance, and (iii) the milestone be reasonable relative to all deliverable and payment terms of the collaboration arrangement. If these criteria are met then the contingent milestones can be considered as substantive milestones and will be recognized as revenue in the period that the milestone is achieved. Royalties are recognized as earned in accordance with the terms of various research and collaboration agreements.

Revenue from the sale of diagnostic products is recorded when there is persuasive evidence that an arrangement exists, delivery has occurred, the price is fixed and determinable or collectability is reasonably assured. Allowances, if any, are established for uncollectible amounts, estimated product returns and discounts. Since allowances are recorded based on management’s estimates, actual amounts may be different in the future.

Research and Development Costs

Research and development costs are expensed as incurred. Costs incurred for clinical trials for patients and investigators are expensed as services are performed in accordance with the agreements in place with the institutions.

Reimbursement of Research & Development Costs

Research and development costs that are reimbursable under collaboration agreements are included as a reduction of research and development expenses. The Company records these reimbursements as a reduction of research and development expenses as the Company’s partner in the collaboration agreement has the financial risks and responsibility for conducting these research and development activities.

Stock-Based Compensation

The Company utilizes stock-based compensation in the form of stock options, stock appreciation rights, stock awards, stock unit awards, performance shares, cash-based performance units and other stock-based awards, each of which may be granted separately or in tandem with other awards.

The grant-date fair value of stock awards is based upon the underlying price of the stock on the date of grant. The grant-date fair value of stock option awards must be determined using an option pricing model. Option pricing models require the use of estimates and assumptions as to (a) the expected term of the option, (b) the expected volatility of the price of the underlying stock and (c) the risk-free interest rate for the expected term of the option. The Company uses the Black-Scholes option pricing formula for determining the grant-date fair value of such awards.

The expected term of the option is based upon the contractual term and expected employee exercise and expected post-vesting employment termination behavior. The expected volatility of the price of the underlying stock is based upon the historical volatility of the Company’s stock computed over a period of time equal to the expected term of the option. The risk free interest rate is based upon the implied yields currently available from the U.S. Treasury yield curve in effect at the time of the grant. Pre-vesting forfeiture rates are estimated based upon past voluntary termination behavior and past option forfeitures.

The following table sets forth the weighted-average assumptions used to calculate the fair value of options granted for the three-month periods ended September 30, 2017 and 2016:


	Three Months Ended
	September 30,
	2017	2016
Expected dividend yield	0%	0%
Expected option term (years)	4.84	5.05
Expected stock price volatility	68%	62%
Risk-free interest rate	1.72% - 1.90%	1.16% - 1.21%

The Company uses historical data to estimate forfeitures. The expected term of options granted represents the period of time that options granted are expected to be outstanding. Expected stock price volatility was calculated based on the Company’s daily stock trading history. The risk-free rate for periods within the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of grant.

Changes in any of these assumptions could impact, potentially materially, the amount of expense recorded in future periods related to stock-based awards.

Common Stock Warrants

In connection with certain financing transactions in October 2016 and February 2017, the Company issued warrants and recorded them as liabilities due to certain net cash settlement provisions. The warrants were recorded at fair value using the Black-Scholes valuation model. The Black-Scholes valuation model takes into account, as of the valuation date, factors including the current exercise price, the term of the warrant, the current price of the underlying stock and its expected volatility, expected dividends on the stock, and the risk-free interest rate for the term of the warrant. These warrants are subject to re-measurement at each balance sheet date until the warrants are exercised or expired, and any change in fair value is recognized as “change in the fair value of warrant liability” in the consolidated statements of operations.

Income Taxes

The Company uses the asset and liability method to account for income taxes, including the recognition of deferred tax assets and deferred tax liabilities for the anticipated future tax consequences attributable to differences between financial statement amounts and their respective tax bases. The Company reviews its deferred tax assets for recovery. A valuation allowance is established when the Company believes that it is more likely than not that its deferred tax assets will not be realized. Changes in valuation allowances from period to period are included in the Company’s tax provision in the period of change. The Company has recorded a full valuation allowance against its net deferred tax assets as of September 30, 2017.

At June 30, 2017, the Company has available net operating loss carry forwards for federal income tax reporting purposes of approximately $371.1 million and for state income tax reporting purposes of approximately $186.0 million, which expire at various dates between fiscal 2018 and 2037. Pursuant to Section 382 of the Internal Revenue Code of 1986, as amended, the annual utilization of a company’s net operating loss and research credit carry forwards may be limited if the Company experiences a change in ownership as defined in Section 382 of the Internal Revenue Code. The Company’s net operating loss carry forwards available to offset future federal taxable income arising before such ownership changes may be limited. Similarly, the Company may be restricted in using its research credit carry forwards arising before such ownership changes to offset future federal income tax expense.

The Company’s U.S. operations and foreign jurisdictions reported a net loss for the three-month periods ended September 30, 2017 and 2016, resulting in a tax benefit that was fully offset by a valuation allowance.

The Company has no liability for uncertain tax positions as of September 30, 2017.

Net Loss Per Share Allocable to Common Stockholders

Net loss per basic and diluted common share allocable to common stockholders is based on the net loss for the relevant period, divided by the weighted-average number of common shares outstanding during the period. For purposes of the diluted net loss per common share calculations, the exercise or exchange of all potential common shares is not included because their effect would have been anti-dilutive, due to the net loss recorded for the three-month periods ended September 30, 2017 and 2016. The common stock equivalents excluded from the diluted per share calculation are 25,685,221 and 26,762,930 shares at September 30, 2017 and 2016, respectively.

Net Comprehensive Loss

Net comprehensive loss consists of net loss, unrealized loss on available for sale securities and foreign exchange translation adjustments and is presented in the condensed consolidated statements of comprehensive loss.

Recently Issued Accounting Pronouncements

In May 2017, the FASB issued ASU 2017-09, "Stock Compensation - Scope of Modification Accounting", guidance that clarifies that all changes to share-based payment awards are not necessarily accounted for as a modification. Under the new guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award changes as a result of the change in terms or conditions. The amendments in this guidance should be applied prospectively in annual periods beginning after December 15, 2017, including interim periods within those periods, with early adoption permitted. This guidance will apply to any future modifications. The Company is assessing ASU 2017-09’s impact and if applicable, will adopt it when effective.

In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows: Clarification of Certain Cash Receipts and Cash Payments”, which eliminates the diversity in practice related to the classification of certain cash receipts and payments in the statement of cash flows, by adding or clarifying guidance on eight specific cash flow issues. ASU 2016-15 is effective for annual and interim reporting periods beginning after December 15, 2017 and early adoption is permitted. ASU 2016-15 provides for retrospective application for all periods presented. The Company is assessing the impact of ASU 2016-15 and will adopt it when effective.

In March 2016, the FASB issued ASU 2016-09, “Improvements to Employee Share-Based Payment Accounting” which simplified 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. Public companies are required to adopt this standard in annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods. The Company implemented ASU 2016-09 effective July 1, 2017, which did not have a material impact on the consolidated financial statement presentation.

In February 2016, the FASB issued ASU 2016-02, “Leases” and issued subsequent amendments to the initial guidance contained within ASU 2017-13. This standard requires a lessee to record on the balance sheet the assets and liabilities for the rights and obligations created by lease terms of more than 12 months. The amendments in this update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years, and early application is permitted. The Company is assessing ASU 2016-02’s impact and will adopt it when effective.

On May 28, 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” and issued subsequent amendments to the initial guidance contained within ASU 2017-13, ASU 2016-20, ASU 2016-12, ASU 2016-10 and ASU 2016-08. Previous revenue recognition guidance in U.S. GAAP comprised broad revenue recognition concepts together with numerous revenue requirements for particular industries or transactions, which sometimes resulted in different accounting for economically similar transactions. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to been titled in exchange for those goods or services. In addition, ASU 2014-09 expands and enhances disclosure requirements which require disclosing sufficient information to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. This includes both qualitative and quantitative information. The amendments in ASU 2014-09 are effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early application is permitted. The guidance permits two methods of adoption: full retrospective in which the standard is applied to all of the periods presented or modified retrospective where an entity will have to recognize the cumulative effect of initially applying the standard as an adjustment to the opening balance of retained earnings. The Company is currently evaluating which transition approach it will utilize and the impact of adopting ASU 2014-09 and subsequent updates will have on its consolidated financial statements and related disclosures. The Company will adopt these standards with an effective date of July 1, 2018.
