Discontinued Operations

For all periods presented, the operating results of our former research and development segment have been excluded from continuing operations and reported as income (loss) from discontinued operations, net of tax in the accompanying unaudited condensed consolidated financial statements for all periods presented. In addition, the assets and liabilities related to our discontinued research and development segment are reported as assets and liabilities of discontinued operations in the accompanying unaudited condensed consolidated balance sheets at January 31, 2019 and April 30, 2018. For additional information on the discontinuation of our research and development segment, refer to Note 10, “Sale of Research and Development Assets”.

Restructuring

Restructuring

Restructuring charges consist of one-time termination benefits, including severance and other employee related costs related to a workforce reduction pursuant to a restructuring plan we implemented in August 2017 (fiscal year 2018). Under this restructuring plan, which we completed in October 2017, we incurred an aggregate of $1,588 in restructuring charges, of which $330 related to our discontinued research and development segment (Note 10) and $1,258 related to our contract manufacturing services segment.

Reclassifications

Reclassifications

Certain prior year amounts related to deferred revenue and customer deposits have been reclassified to contract liabilities in our accompanying consolidated balance sheet for the fiscal year ended April 30, 2018 and in our accompanying consolidated statement of cash flows for the nine months ended January 31, 2018 to conform to the current period presentation (Note 2). This reclassification had no effect on previously reported net loss.

Revenue Recognition

We derive revenue from contract manufacturing services provided under our customer contracts, which we have disaggregated into the following revenue streams:

Manufacturing revenue

The manufacturing revenue stream represents revenue from the manufacturing of customer product(s) derived from mammalian cell culture covering clinical through commercial manufacturing runs. Under a manufacturing contract, a quantity of manufacturing runs are ordered and the product is manufactured according to the customer’s specifications and typically only one performance obligation is included. Each manufacturing run represents a distinct service that is sold separately and has stand-alone value to the customer. The product(s) are manufactured exclusively for a specific customer and have no alternative use. The customer retains control of their product during the entire manufacturing process and can make changes to the process or specifications at their request. Under these agreements, we are entitled to consideration for progress to date that includes an element of profit margin. Revenue associated with this stream is recognized over time utilizing an input method that compares the cost of cumulative work-in-process to date to the most current estimates for the entire cost of the performance obligation.

Process development revenue

The process development revenue stream represents revenue from non-manufacturing related services associated with the custom development of a customer’s product. Under a process development contract, the customer owns the product details and process, which has no alternative use. These process development projects are customized to each customer to meet their specifications and typically only one performance obligation is included. Each process represents a distinct service that is sold separately and has stand-alone value to the customer. The customer also retains control of their product as the product is being created or enhanced by our services and can make changes to their process or specifications upon request. Revenue associated with this stream is recognized over time utilizing an input method that compares the cost of cumulative work-in-process to date to the most current estimates for the entire cost of the performance obligation.

The following table disaggregates our contract manufacturing revenue for the three and nine months ended January 31, 2019 and 2018 by revenue stream. Contract manufacturing revenue for the three and nine months ended January 31, 2018 has not been adjusted in accordance with our modified retrospective adoption of ASC 606 and continues to be reported under the accounting standards that were in effect prior to our adoption of ASC 606 on May 1, 2018:

	Three Months Ended January 31,				Nine Months Ended January 31,
	2019		2018		2019		2018
Manufacturing revenue	$	10,770	$	6,045	$	28,313	$	42,281
Process development revenue		3,011		774		8,235		4,397
Total contract manufacturing revenue	$	13,781	$	6,819	$	36,548	$	46,678

Contract balances

The timing of revenue recognition, billings and cash collections results in billed trade receivables, contract assets (unbilled receivables), and contract liabilities (customer deposits and deferred revenue). Contract assets are recorded when our right to consideration is conditioned on something other than the passage of time. Contract assets are reclassified to trade receivables on the balance sheet when our rights become unconditional. Contract liabilities represent customer deposits and deferred revenue billed and/or received in advance of our fulfillment of performance obligations. Contract liabilities will convert to contract manufacturing revenue as we perform our obligations under the contract.

We recognized contract manufacturing revenue of $2,208 and $12,233, respectively, during the three and nine months ended January 31, 2019 for which the contract liability was recorded in the prior year.

Practical expedients and contract costs

We apply the practical expedient available under ASC 606 that permits us not to disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less. In addition, we currently do not have any unsatisfied performance obligations for contracts greater than one year.

Costs incurred to obtain or fulfill a contract are not material. These costs are generally employee sales commissions, which are expensed when incurred and included in selling, general and administrative expense in the accompanying condensed consolidated statements of operations and comprehensive loss.

Restricted Cash

Restricted Cash

Under the terms of three separate operating leases related to our facilities, we are required to maintain, as collateral, letters of credit during the terms of such leases. At January 31, 2019 and April 30, 2018, restricted cash of $1,150 was pledged as collateral under these letters of credit.

Fair Value Measurements

Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The guidance prioritizes the inputs used in measuring fair value into the following hierarchy:

·

Level 1 – Observable inputs, such as unadjusted quoted prices in active markets for identical assets or liabilities.

·

Level 2 – Observable inputs other than quoted prices included in Level 1, such as assets or liabilities whose values are based on quoted market prices in markets where trading occurs infrequently or whose values are based on quoted prices of instruments with similar attributes in active markets.

·

Level 3 – Unobservable inputs that are supported by little or no market activity and significant to the overall fair value measurement of the assets or liabilities; therefore, requiring the company to develop its own valuation techniques and assumptions.

As of January 31, 2019 and April 30, 2018, we do not have any Level 2 or Level 3 financial assets or liabilities and our cash equivalents, which are primarily invested in money market funds with one major commercial bank, are carried at fair value based on quoted market prices for identical securities (Level 1 input). In addition, there were no transfers between any Levels of the fair value hierarchy during the three and nine months ended January 31, 2019 and 2018.

Income Taxes

Income Taxes

Deferred income tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial reporting and tax bases of assets and liabilities and are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. A valuation allowance is provided for the amount of deferred tax assets that, based on available evidence, are not expected to be realized. As a result of our cumulative losses, management has concluded that a full valuation allowance against our net deferred tax assets is appropriate.

The income tax benefit recognized in the accompanying unaudited condensed consolidated statements of operations and comprehensive loss during the three and nine months ended January 31, 2019 resulted from the “Intraperiod Tax Allocation” rules under ASC 740: Income Taxes (“ASC 740”), which requires the allocation of an entity’s total annual income tax provision among continuing operations and, in our case, discontinued operations. Accordingly, a tax benefit was recorded in continuing operations with an offsetting tax expense recorded in discontinued operations (Note 10).

In December 2017, the Tax Cuts and Jobs Act (the “Tax Act”) was enacted. The Tax Act includes a number of changes to existing U.S. tax laws that impact us, most notably a reduction of the U.S. corporate income tax rate from 35 percent to 21 percent for tax years, effective January 1, 2018. We performed a review of the Tax Act for the fiscal year ended April 30, 2018, and based on the information available at that time, recorded certain provisional amounts related to the revaluation of our deferred tax assets and liabilities, which were fully offset by a valuation allowance.

We applied the guidance under Staff Accounting Bulletin No. 118 when accounting for the enactment-date effects of the Tax Act for the fiscal year ended April 30, 2018 as we had not completed our accounting for all the enactment-date income tax effects of the Tax Act under ASC 740 for the remeasurement of deferred tax assets and liabilities. We have now completed our accounting for the enactment-date income tax effects of the Tax Act. Upon further analyses of the Tax Act and Notices and regulations issued and proposed by the U.S. Department of the Treasury and the Internal Revenue Service our provisional amount recognized for the fiscal year ended April 30, 2018 did not change; therefore, there was no adjustment to tax expense.

New Accounting Standards Not Yet Adopted

New Accounting Standards Not Yet Adopted

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The new standard requires lessees to recognize right-of-use assets and lease liabilities on its balance sheet for all leases with lease terms greater than 12 months and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. ASU 2016-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, which will be our fiscal year 2020 beginning May 1, 2019. Early adoption is permitted. While we continue to assess the impact of the new guidance, we believe the primary effect of adopting ASU 2016-02 will be to record right-of-use assets and corresponding obligations for our operating leases, which we believe will have a material impact our condensed consolidated financial statements and related disclosures.
