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 January 31, 2020 and April 30, 2019 the Company had no cash equivalents.

Liquidity

Our 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. In the past, we have met these cash requirements through our cash, working capital management, proceeds from certain private placements and public offerings of our securities, and sales of products and services. For the nine months ended January 31, 2020, the Company had net income of approximately $72,000 and cash flow from operations of $360,000. As of January 31, 2020, the Company had an accumulated deficit of approximately $70.6 million, a working capital deficit of $0.3 million and cash of $3.3 million. We believe that our cash on hand, together with expected net positive cash flows from operations for fiscal year 2020, are adequate to fund operations through at least 12 months from the filing of this 10-Q. However, should our revenue expectations not materialize, we believe we have 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.

Leases

Effective May 1, 2019, the Company accounts for its leases under 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 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 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. The Company continues to account for leases in the prior period financial statements in accordance with ASC Topic 840.

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

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 operating 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 performed a Section 382 study and concluded that there are adequate NOL's available to offset any net income generated during the fiscal year ending April 30, 2020. 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, 2020 and April 30, 2019, 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 $151,000 of liabilities related to uncertain tax positions relative to one of its foreign operations as of January 31, 2020 and April 30, 2019.

The Company’s practice is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company had no accrual for interest or penalties on the Company’s balance sheets at January 31, 2020 and April 30, 2019, and has not recognized interest and/or penalties in the statement of operations for either period. We do not anticipate any significant unrecognized tax benefits will be recorded during the next 12 months.

The provision for the income taxes for the three months ended January 31, 2020 and 2019 was $12,000 and $0. The provision for income taxes for the nine months ended January 31, 2020 and 2019 was $38,000 and $0, respectively.

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, POS Services 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

In August 2018, the Financial Accounting Standards Board ("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. The update is effective for public business entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption of the amendments in this update is permitted, including adoption in any interim period. We are currently assessing the impact of this update on our consolidated financial statements.

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, 2019 for public entities. Early adoption is permitted. We are currently assessing the impact of this update on our consolidated financial statements.

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 of $4.1 million 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 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 has 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.
