Accounting Policies [Abstract] |
Cash and Cash Equivalents | Cash and Cash EquivalentsThe 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.
Leases | LeasesEffective May 1, 2019, the Company accounts for its leases under Accounting Standards Codification ("ASC") Topic 842, Leases. Under this guidance, arrangements meeting the definition of a lease are classified as operating or financing leases and are recorded on the consolidated balance sheet as both a right-of-use asset and lease liability, calculated by discounting fixed lease payments over the lease term at the rate implicit in the lease, if applicable, or the Company’s incremental borrowing rate. As the Company's leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at the lease commencement date in determining the present value of lease payments. Lease liabilities are increased by interest and reduced by payments each period, and the right-of-use asset is amortized over the lease term. For operating leases, interest on the lease liability and the amortization of the right-of-use asset result in straight-line rent expense over the lease term.
Earnings Per Share | 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 or loss 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 purchase warrants and stock options.
Income Taxes | 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. Our ability to utilize net operating losses (“NOL”) carryforwards to offset our future taxable income would be limited if we have 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 January 31, 2021 and April 30, 2020, the Company provided a valuation allowance for all net deferred tax assets, as recovery is not more likely than not based on an insufficient history of earnings. Tax positions are positions taken in a previously filed tax return or positions expected to be taken in a future tax return that are reflected in measuring current or deferred income tax assets and liabilities reported in the consolidated financial statements. Tax positions include, but are not limited to, the following: •An allocation or shift of income between taxing jurisdictions; •The characterization of income or a decision to exclude reportable taxable income in a tax return; or •A decision to classify a transaction, entity or other position in a tax return as tax exempt. 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 and $178,000 of liabilities related to uncertain tax positions relative to one of its foreign operations as of January 31, 2021 and April 30, 2020, respectively. The Company’s practice is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company recognized approximately $3,000 for interest and penalties on the Company’s balance sheets as of January 31, 2021, and recognized approximately $3,000 of interest and penalties in the statement of operations for the nine months ended January 31, 2021. Other than approximately $4,500 for interest and penalties, the Company does not anticipate additional unrecognized tax benefits will be recorded during the next 12 months.
Revenue Recognition | Revenue Recognition 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. 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. 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 from the timing of payment terms and when an input method of revenue recognition is utilized and revenue recognized exceeds the amount billed to the customer. 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.
Accounting Pronouncements Being Evaluated/Recently Adopted Accounting Pronouncements | Accounting Pronouncements Being Evaluated In October 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-10, Codification Improvements. The purpose of the ASU is to clarify, correct errors in, or make minor improvements to a variety of ASC topics. The changes in ASU 2020-03 are not expected to have a significant effect on the Company's current accounting practices. The ASU improves various topics in the Codification to increase stakeholder awareness of the amendments and to expedite the improvement process by making the Codification easier to understand and easier to apply by eliminating inconsistencies and providing clarifications. The ASU is effective for fiscal years beginning after December 15, 2020 with early application permitted. We are currently assessing the impact of this update on our consolidated financial statements and do not anticipate a significant impact. In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes. The ASU enhances and simplifies various aspects of the income tax accounting guidance in ASC Topic 740 and removes certain exceptions for recognizing deferred taxes for investments, performing intraperiod allocation and calculating income taxes in interim periods. The ASU also adds guidance to reduce complexity in certain areas, including recognizing deferred taxes for tax goodwill and allocating taxes to members of a consolidated group. This ASU is effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years with early adoption permitted. We are currently assessing the impact of this update on our consolidated financial statements and do not anticipate a significant impact. In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments - Credit Losses". This update requires immediate recognition of management’s estimates of current expected credit losses ("CECL"). Under the prior model, losses were recognized only as they were incurred. The new model is applicable to all financial instruments that are not accounted for at fair value through net income. The standard is effective for fiscal years beginning after December 15, 2022 for public entities qualifying as small reporting companies. Early adoption is permitted. We are currently assessing the impact of this update on our consolidated financial statements and do not anticipate a significant impact. Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, "Leases", (Topic 842), which required the Company to recognize lease assets and lease liabilities (related to leases previously classified as operating under previous U.S. GAAP) on its consolidated balance sheet for all leases in excess of one year in duration. The ASU was effective for the Company on May 1, 2019. The Company elected to adopt ASU 2016-02 using the modified retrospective method and, therefore, have not recast comparative periods presented in its unaudited consolidated financial statements. As permitted under ASU 2016-02, the Company elected to account for the non-lease components together with the lease components as a single lease component. The Company recorded an operating lease right-of-use ("ROU") asset of $3.2 million, net of deferred rent of $900,000 and an operating lease liability of $4.1 million as of May 1, 2019. See Note 8 of this Form 10-Q for additional information and required disclosures. Under Topic 842, the Company determined if an arrangement is a lease at inception. ROU assets and liabilities are recognized at commencement date based on the present value of remaining lease payments over the lease term. For this purpose, the Company considers only payments that are fixed and determinable at the time of commencement. As the Company's leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. In August 2018, the FASB issued ASU 2018-15, which amends ASC 350-40, Intangibles—Goodwill and Other—Internal-Use Software, to address a customer’s accounting for implementation costs incurred in a cloud computing arrangement ("CCA") that is a service contract. This update aligns the accounting for costs incurred to implement a CCA that is a service arrangement with the guidance on capitalizing costs associated with developing or obtaining internal-use software. This ASU was effective for and adopted by the Company on May 1, 2020. The adoption had no material impact on our consolidated financial statements. In June 2018, the FASB issued ASU 2018-07, "Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting". This ASU expands the scope of Topic 718, Compensation—Stock Compensation (which currently only includes share-based payments to employees) to include share-based payments issued to nonemployees for goods or services. Under the new guidance, the existing employee guidance will apply to nonemployee share based transactions (as long as the transaction is not effectively a form of financing), with the exception of specific guidance related to the attribution of compensation cost. The cost of nonemployee awards will continue to be recorded as if the grantor had paid cash for the goods or services. The new accounting guidance was effective for the Company on May 1, 2019. The Company adopted this new rule beginning with its financial reporting for the quarter ended January 31, 2019. The adoption had no material impact on our consolidated financial statements.On November 11, 2019, the FASB issued ASU 2019-08 which clarifies the accounting for share-based payments issued as consideration payable to a customer in accordance with ASC 606. Under the ASU, entities apply the guidance in ASC 718 to measure and classify share-based payments issued to a customer that are not in exchange for a distinct good or service (i.e., share-based sales incentives). The ASU was effective for the Company on May 1, 2020 and the adoption had no material impact on our consolidated financial statements.
