Summary of Significant Accounting Policies [Abstract] |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies In addition to the policies below, our significant accounting policies are described in Note 2 of the Notes to Consolidated Financial Statements included in our 2016 Form 10-K. There were no changes to these policies during the three months ended March 31, 2017. Concentration of Risks We are subject to credit risk from our portfolio of cash and cash equivalents. Under our investment policy, we limit amounts invested in such securities by credit rating, maturity, industry group, investment type and issuer, except for securities issued by the U.S. government. Cash is held at major banks in the United States. Therefore, the Company is not exposed to any significant concentrations of credit risk from these financial instruments. The goals of our investment policy, in order of priority, are as follows: safety and preservation of principal and diversification of risk; liquidity of investments sufficient to meet cash flow requirements, and a competitive after-tax rate of return. We are also subject to credit risk from our accounts receivable related to our services. The majority of our trade accounts receivable arises from services in the United States. For the three months ended March 31, 2017, the three largest customers represented 59% of total revenues recognized, the largest of which was 23%. As of March 31, 2017, three customers represented 66% of our accounts receivable, the largest of which was 32%. Share-Based Compensation The Company expenses all share-based payment awards to employees, directors, consultants, including grants of stock options, warrants, and restricted stock, over the requisite service period based on the grant date fair value of the awards. Consultant awards are remeasured each reporting period through vesting. For awards with performance-based vesting criteria, the Company estimates the probability of achievement of the performance criteria and recognizes compensation expense related to those awards expected to vest. The Company determines the fair value of option awards using the Black-Scholes option-pricing model which uses both historical and current market data to estimate the fair value. This method incorporates various assumptions such as the risk-free interest rate, expected volatility, expected dividend yield and expected life of the options or warrants. The fair value of the Company’s restricted stock and restricted stock units is based on the closing market price of the Company’s common stock on the date of grant. Goodwill Goodwill is the excess of purchase price over the fair value of identified net assets of businesses acquired. Intangible assets with indefinite useful lives are measured at their respective fair values as of the acquisition date. The Company does not amortize goodwill and intangible assets with indefinite useful lives. The Company reviews goodwill at least annually, or at the time a triggering event is identified for possible impairment. Goodwill is reviewed for possible impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying value. The Company tests its goodwill each year on December 31. The Company reviews the carrying value of goodwill utilizing an income approach model, and, where appropriate, a market value approach is also utilized to supplement the discounted cash flow model. The Company makes assumptions regarding estimated future cash flows, discount rates, long-term growth rates and market values to determine each reporting unit’s estimated fair value. If these estimates or related assumptions change in the future, the Company may be required to record impairment charges. In accordance with its accounting policy, the Company tested goodwill for impairment as of December 31, 2016 and concluded there was no goodwill impairment. Long-Lived Assets Long-lived assets consist of customer lists, manufacturing technology, tradenames, patents and rights, as well as property, plant and equipment. The assets are amortized on a straight line basis over their respective useful lives. The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset exceeds the fair value of the asset. If other events or changes in circumstances indicate that the carrying amount of an asset that the Company expects to hold and use may not be recoverable, the Company will estimate the undiscounted future cash flows expected to result from the use of the asset and/or its eventual disposition, and recognize an impairment loss, if any. The impairment loss, if determined to be necessary, would be measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. No triggering events were noted in the quarters ended March 31, 2017 or March 31, 2016 that would require interim impairment assessment. Revenue Recognition Clinical Services: The Company recognizes revenue for its (i) process development and (ii) clinical manufacturing services based on the terms of individual contracts. We recognize revenues when all of the following conditions are met:
• | persuasive evidence of an arrangement exists;
• | delivery has occurred or the services have been rendered;
• | the fee is fixed or determinable; and
• | collection is probable.
The Company considers signed contracts as evidence of an arrangement. The Company assesses whether the fee is fixed or determinable based on the payment terms associated with the transaction and whether the payment terms are subject to refund or adjustment. The Company assesses cash collectability based on a number of factors, including past collection history with the client and the client's creditworthiness. If the Company determines that collectability is not reasonably assured, it defers revenue recognition until collectability becomes reasonably assured, which is generally upon receipt of the cash. The Company's arrangements are generally non-cancellable, though clients typically have the right to terminate their agreement for cause if the Company materially fails to perform. Revenues associated with process development services generally contain multiple stages that do not have stand-alone values and are dependent upon one another, and are recognized as revenue on a completed contract basis. Progress billings collected prior to contract completion are recorded as unearned revenue until such time the contract is completed, which usually requires formal client acceptance. Clinical manufacturing services are generally distinct arrangements whereby the Company is paid for time and materials or for fixed monthly amounts. Revenue is recognized when contractual terms have been met. Some client agreements include multiple elements, comprised of cell process development and cell manufacturing services. The Company believes that process development and clinical manufacturing services each have stand-alone value because these services can be provided separately by other companies. In accordance with ASC Update No. 2009-13, “Revenue Recognition (Topic 605): Multiple-Deliverable Revenue Arrangements,” the Company (1) separates deliverables into separate units of accounting when deliverables are sold in a bundled arrangement and (2) allocates the arrangement's consideration to each unit in the arrangement based on its relative selling price. Clinical Services Reimbursements: The Company separately charges the customers for the expenses associated with certain consumable resources (reimbursable expenses) that are specified in each clinical services contract. On a monthly basis, the Company bills customers for reimbursable expenses and immediately recognizes these billings as revenue, as the revenue is deemed earned as reimbursable expenses are incurred. For the three months ended March 31, 2017 and 2016, clinical services reimbursements were $1.7 million and $1.3 million, respectively. Processing and Storage Services: The Company recognizes revenue related to the collection and cryopreservation of autologous adult stem cells when the cryopreservation process is completed which is approximately twenty-four hours after cells have been collected. Revenue related to advance payments of storage fees is recognized ratably over the period covered by the advance payments. License Fees: PCT and Hitachi Chemical also entered into an exclusive license agreement for Asia pursuant to which PCT received $5.6 million from Hitachi Chemical in 2016. PCT licensed to Hitachi Chemical certain cell therapy technology and know-how (including an exclusive license to use the PCT brand in Asia) and agreed to provide Hitachi Chemical with certain training and support. As additional consideration, Hitachi Chemical will pay PCT royalties on contract revenue generated in Asia for a minimum of ten years. The initial term of the Hitachi License Agreement is ten years and may be automatically extended for successive additional two year terms. The Company recognizes the payments as revenue on a straight-line basis over the initial ten-year term. For the three months ended March 31, 2017 and 2016, the Company recognized $0.14 million and $0.02 million of license fee revenue, respectively. As of March 31, 2017, $0.6 million of Hitachi license fees were included in unearned revenue, and $4.4 million was included in unearned revenue - long-term. Recently Issued Accounting Pronouncement In May 2014, the FASB issued Accounting Standards Update No. 2014-09, “Revenue from Contracts with Customers” (ASU 2014-09) and has subsequently issued a number of amendments to ASU 2014-09. The new standard, as amended, provides a single comprehensive model to be used in the accounting for revenue arising from contracts with customers and supersedes current revenue recognition guidance, including industry-specific guidance. The standard’s stated core principle 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 be entitled in exchange for those goods or services. To achieve this core principle, ASU 2014-09 includes provisions within a five-step model that includes identifying the contract with a customer, identifying the performance obligations in the contract, determining the transaction price, allocating the transaction price to the performance obligations, and recognizing revenue when, or as, an entity satisfies a performance obligation. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The new standard will be effective for us beginning January 1, 2018 and permits two methods of adoption: the full retrospective method, which requires the standard to be applied to each prior period presented, or the modified retrospective method, which requires the cumulative effect of adoption to be recognized as an adjustment to opening retained earnings in the period of adoption. The Company is currently evaluating the impact of the pending adoption of ASU 2014-09 on its consolidated financial statements and has not yet selected the transition method. The Company anticipates assigning internal resources to assist with the evaluation and implementation of the new standard, and will continue to provide updates during 2017. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This ASU requires that a lessee recognize lease assets and lease liabilities for those leases classified as operating leases. The guidance is effective for interim and annual periods beginning after December 15, 2018, and will be applied at the beginning of the earliest period presented using a modified retrospective approach. This ASU may have a material impact on the Company’s financial statements. The impact on the Company’s results of operations is currently being evaluated. The impact of the ASU is non-cash in nature and will not affect the Company’s cash position. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting. This ASU simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, accounting for forfeitures, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The guidance is effective for interim and annual periods beginning after December 15, 2016, with early adoption permitted. The guidance will be applied prospectively, retrospectively, or by means of a cumulative-effect adjustment to equity as of the beginning of the period in which the guidance is adopted, dependent upon the specific amendment that is adopted within the ASU. The adoption of this new guidance did not have a material effect on the consolidated results of operations, cash flows, and financial position. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 clarifies how companies present and classify certain cash receipts and cash payments in the statement of cash flows where diversity in practice exists. ASU 2016-15 is effective in first quarter of fiscal 2018 and earlier adoption is permitted. The Company is currently evaluating the effect that the updated standard will have on the consolidated financial statements and related disclosures. In October 2016, the FASB issued ASU 2016-16, Intra-Entity Transfers of Assets Other Than Inventory. ASU 2016-16 requires the income tax consequences of intra-entity transfers of assets other than inventory to be recognized as current period income tax expense or benefit at the transaction date and removes the option to defer and amortize the consolidated tax consequences of intra-entity transfers. The new standard will be effective on January 1, 2018 and will be adopted using a modified retrospective approach which requires a cumulative effect adjustment to retained earnings as of the beginning of the period of adoption. Early adoption is permitted at the beginning of a fiscal year. The Company is currently evaluating the effect that the updated standard will have on the consolidated financial statements and related disclosures.
