| Significant Accounting Policies | Significant Accounting Policies Cash and Cash Equivalents The Company considers only those investments which are highly liquid, readily convertible to cash, and with original maturities of three months or less to be cash equivalents. As of October 31, 2023 the Company had cash equivalents of $3.6 million and, as of April 30, 2023, the Company had no cash equivalents. The Company is subject to a concentration of credit risk in the form of its cash deposits held at multiple banking institutions. Accounts at each institution are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000. As of October 31, 2023 and April 30, 2023, the Company had $4.3 million and $8.7 million in excess of the FDIC insured limit, respectively. Liquidity The Company's liquidity needs have typically arisen from the funding of our research and development programs and the launch of new products, working capital requirements, and other strategic initiatives. Recently, the Company has met these cash requirements through cash on hand, working capital management, and sales of products and services. In the past, the Company has also received proceeds from certain private placements and public offerings of its securities. For the six months ended October 31, 2023, the Company had a net loss of approximately $4.6 million and cash used in operations of approximately $3.4 million. As of October 31, 2023, the Company had an accumulated deficit of approximately $82.0 million and cash on hand of approximately $5.5 million. The Company believes that cash on hand, together with expected cash to be provided from operations for the remainder of fiscal year 2024, are adequate to fund operations through at least 12 months from the filing of this Quarterly Report on Form 10-Q (this "Report"). However, should the Company's revenue expectations not materialize, the Company believes it has cost reduction strategies that could be implemented without disrupting the business or restructuring the Company. Should the Company be required to raise additional capital, there can be no assurance that management would be successful in raising such capital on terms acceptable to us, if at all. Fair Value The carrying value of cash, accounts receivable, prepaid expenses, and other current assets, accounts payable, and accrued liabilities approximate their fair value based on the liquidity or the short-term maturities of these instruments. The fair value hierarchy promulgated by GAAP consists of three levels: •Level one — Quoted market prices in active markets for identical assets or liabilities; •Level two — Inputs other than level one inputs that are either directly or indirectly observable; and •Level three — Unobservable inputs developed using estimates and assumptions, which are developed by the reporting entity and reflect those assumptions that a market participant would use. Determining which category an asset or liability falls within the hierarchy requires significant judgment. The Company evaluates its hierarchy disclosures each quarter. As of October 31, 2023 the Company had assets measured at fair value on a recurring and/or non-recurring basis as follows: (in 000s) October 31, 2023 Level 1 Level 2 Level 3 Cash Equivalents: Money market fund 3,554 — — Total $ 3,554 $ — $ — As of October 31, 2023, the Company had no liabilities measured at fair value on a recurring and/or non-recurring basis. As of April 30, 2023, the Company had no assets or liabilities measured at fair value on a recurring and/or non-recurring basis. Earnings Per Share Basic net income or loss per share is computed by dividing the net income or loss for the period by the weighted-average number of shares of common stock outstanding during the period. Diluted net income per share is computed by dividing the net income for the period by the weighted-average number of shares of common stock plus dilutive potential common stock considered outstanding during the period. Such dilutive shares consist of incremental shares that would be issued upon exercise of the Company’s common stock options. As of October 31, 2023 and 2022, all of the Company's potential common stock is considered anti-dilutive. The following table reflects the total potential share-based instruments outstanding at October 31, 2023 and 2022 including those that could have an effect on the future computation of dilution per common share, had their effect not been anti-dilutive due to the Company's net losses in the related periods: October 31, 2023 2022 Total common stock equivalents 1,831,867 1,675,447 Income Taxes Deferred income taxes have been provided to show the effect of temporary differences between the recognition of expenses for financial and income tax reporting purposes and between the tax basis of assets and liabilities, and their reported amounts in the consolidated financial statements. In assessing the realizability of deferred tax assets, the Company assesses the likelihood that deferred tax assets will be recovered through tax planning strategies or from future taxable income, and to the extent that recovery is not likely or there is insufficient earnings history, a valuation allowance is established. The Company's ability to utilize net operating losses (“NOL”) carryforwards to offset future taxable income would be limited if the Company had undergone or were to undergo an “ownership change” within the meaning of Section 382 of the Internal Revenue Code (the “IRC”). The Company adjusts the valuation allowance in the period management determines it is more likely than not that deferred tax assets will or will not be realized. Changes in valuation allowances from period to period are included in the tax provision in the period of change. As of October 31, 2023 and April 30, 2023, the Company provided a valuation allowance for all net deferred tax assets as it is more likely than not that the assets will not be recovered based on an insufficient history of earnings. The Company reflects tax benefits only if it is more likely than not that the Company will be able to sustain the tax position, based on its technical merits. If a tax benefit meets this criterion, it is measured and recognized based on the largest amount of benefit that is cumulatively greater than 50% likely to be realized. The Company recorded $181,000 of liabilities related to uncertain tax positions relative to one of its foreign operations as of October 31, 2023 and April 30, 2023. The Company’s practice is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company did not recognize interest or penalties on its consolidated statements of operations during the three and six-month periods ended October 31, 2023 and 2022. The Company does not anticipate unrecognized tax benefits will be recorded during the next 12 months. The provision for income taxes for the three months ended October 31, 2023 and 2022 was $11,000 and $14,000, respectively. The provision for income taxes for the six months ended October 31, 2023 and 2022 was $39,000 and $31,000, respectively. The provision is mainly attributable to taxable income earned in Israel and/or Italy relating to transfer pricing. Revenue Recognition The Company recognizes revenue in accordance with Accounting Standards Codification ("ASC") 606 ("ASC 606"), Revenue from Contracts with Customers. Under this standard, companies recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration to which the Company expects to be entitled in exchange for those goods or services. All revenue is generated from contracts with customers. The Company's arrangements are service type contracts that mainly have a duration of less than a year. The Company recognizes revenue when control of these services is transferred to the customer in an amount, referred to as the transaction price, that reflects the consideration to which the Company is expected to be entitled in exchange for those services. The Company determines revenue recognition utilizing the following five steps: (1) identification of the contract with a customer, (2) identification of the performance obligations in the contract (promised goods or services that are distinct), (3) determination of the transaction price, (4) allocation of the transaction price to the performance obligations, and (5) recognition of revenue when, or as, the Company transfers control of the product or service for each performance obligation. The Company records revenues net of any tax assessments by governmental authorities, such as value added taxes, that are imposed on and concurrent with specific revenue generating transactions. The majority of the Company's revenue arrangements are service contracts that are completed within a year or less. There are a few contracts that range in duration between 1 and 3 years. Substantially all of the Company's performance obligations, and associated revenue, are transferred to the customer over time. Most of the Company's contracts can be terminated by the customer without cause. In the event of termination, the Company's contracts provide that the customer pay the Company for services rendered through the termination date. The Company generally receives compensation based on a predetermined invoicing schedule relating to specific milestones for that contract. Amendments to contracts are common. The Company evaluates each amendment which meets the criteria of a contract modification under ASC 606. Each modification is further evaluated to determine whether the contract modification should be accounted for as a separate contract or as a continuation of the original agreement. The Company accounts for amendments as a separate contract as they meet the criteria under ASC 606-10-25-12. Pharmacology Study and Other Services The Company generally enters into contracts with customers to provide oncology services with payments based on fixed-fee arrangements. At contract inception, the Company assesses the services promised in the contracts with customers to identify the performance obligations in the arrangement. The Company's fixed-fee arrangements for oncology services are considered a single performance obligation because the Company provides a highly-integrated service. The Company recognizes revenue over time using a progress-based input method since there is no single output measure that would fairly depict the transfer of control over the life of the performance obligation. Revenue is recognized for the single performance obligation over time due to the Company's right to payment for work performed to date and the performance does not create an asset with an alternative use. The Company recognizes revenue as portions of the overall performance obligation are completed as this best depicts the progress of the performance obligation. Incremental Costs of Obtaining a Contract (Sales Commissions) Under ASC 606, the costs of obtaining a contract can be expensed immediately, rather than capitalized and amortized, if the amortization period is one year or shorter. Sales commissions for the Company represent contract costs with a term of one year or less. Therefore, under ASC 606, the Company elected the practical expedient to expense these costs as incurred. Variable Consideration In some cases, contracts provide for variable consideration that is contingent upon the occurrence of uncertain future events, such as the success of the initial performance obligation. Variable consideration is estimated at the expected value or at the most likely amount depending on the type of consideration. Estimated amounts are included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The estimate of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of its anticipated performance and all information (historical, current and forecasted) that is reasonably available to the Company. Trade Receivables, Unbilled Services and Deferred Revenue In general, billings and payments are established by contractual provisions including predetermined payment schedules, which may or may not correspond to the timing of the transfer of control of the Company's services under the contract. In general, the Company's intention in its invoicing (payment terms) is to maintain cash neutrality over the life of the contract. Upfront payments, when they occur, are intended to cover certain expenses the Company incurs at the beginning of the contract. Neither the Company nor its customers view such upfront payments and contracted payment schedules as a means of financing. Unbilled services primarily arise when the revenue recognized exceeds the amount billed to the customer. Such situations occur due to divergences between revenue recognition and the invoicing milestones which are based on predetermined payment terms. Deferred revenue consists of unearned payments received in excess of revenue recognized. As the contracted services are subsequently performed and the associated revenue is recognized, the deferred revenue balance is reduced by the amount of the revenue recognized during the period. Deferred revenue is classified as a current liability on the condensed consolidated balance sheet as the Company expects to recognize the associated revenue in less than one year. Recently Adopted Accounting Pronouncements In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, “Financial Instruments—Credit Losses” (Topic 326). This ASU represents a significant change in the current accounting model by requiring immediate recognition of management’s estimates of current expected credit losses. Under the prior model, losses were recognized only as they were incurred, which delayed recognition of expected losses that might not yet have met the threshold of being probable. The Company adopted ASU 2016-03 on April 1, 2023 and the adoption did not have any material effect on our condensed consolidated financial statements and related disclosures. |
