The Company’s condensed consolidated financial statements include the accounts of its subsidiary, UPI. Intercompany balances and transactions have been eliminated during consolidation.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates. As applicable to the unaudited condensed consolidated financial statements, the most significant estimates and assumptions relate to the fair value of share-based compensation, the fair value of the warrants for preferred shares and timing of revenue recognition.

The U.S. dollar (“Dollar”) is the currency of the primary economic environment in which the operations of the Company are conducted. Therefore, the functional currency of the Company is the Dollar.

Accordingly, transactions in currencies other than the Dollar are measured and recorded in the functional currency using the exchange rate in effect at the date of the transaction. At the balance sheet date, monetary assets and liabilities that are denominated in currencies other than the Dollar are measured using the official exchange rate at the balance sheet date. The effects of foreign currency re-measurements are recorded in the condensed consolidated statements of operations as “finance (income) expenses.”

The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Cash and cash equivalents consist primarily of money market funds and bank money market accounts and are stated at cost, which approximates fair value.

The Company from time to time invests in short-term investments that consist of mutual and bond funds. While these investments are considered highly liquid and available to fund current operations, there is more than an insignificant risk of change in value due to interest rate, quoted price, or penalty on withdrawal and are therefore classified as short-term investments.

The Company classifies its short-term investments as available-for-sale in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 320, “Investments — Debt and Equity Securities”. Available-for-sale debt securities are carried at fair value with unrealized gains and losses reported in other comprehensive income/loss within shareholders’ equity.

Short-term investments are valued using models or other valuation methodologies that use Level 2 inputs. These models are primarily industry-standard models that consider various assumptions, including time value, yield curve, volatility factors, default rates, current market and contractual prices for the underlying financial instruments, as well as other relevant economic measures. The majority of these assumptions are observable in the marketplace, can be derived from observable data or are supported by observable levels at which transactions are executed in the marketplace.

Financial instruments, which potentially subject the Company to significant concentrations of credit risk, consist primarily of cash and cash equivalents and marketable securities. The primary objectives for the Company’s investment portfolio are the preservation of capital and the maintenance of liquidity. The Company does not enter into any investment transaction for trading or speculative purposes.

The Company’s investment policy limits investments to certain types of instruments such as certificates of deposit, money market instruments, obligations issued by the U.S. government and U.S. government agencies as well as corporate debt securities, and places restrictions on maturities and concentration by type and issuer. The Company maintains cash balances in excess of amounts insured by the Federal Deposit Insurance Corporation and concentrated within a limited number of financial institutions. The accounts are monitored by management to mitigate the risk.

Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash and cash equivalents and short-term investments. The Company deposits cash and cash equivalents with highly rated financial institutions, has not experienced any credit losses in these accounts and does not believe it is exposed to significant credit risk on these instruments.

The Company provides for income taxes based on pretax income, if any, and applicable tax rates available in the various jurisdictions in which we operate. Deferred taxes are computed using the asset and liability method. Under the asset and liability method, deferred income tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities and are measured using the currently enacted tax rates and laws. A valuation allowance is recognized to the extent that it is more likely than not that the deferred taxes will not be realized in the foreseeable future.

The Company follows a two-step approach in recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if the available evidence indicates that it is more likely than not that the position will be sustained upon examination by the taxing authorities based on the technical merits of the position. If this threshold is met, the second step is to measure the tax benefit as the largest amount that is more likely than not of being realized upon ultimate settlement. As of March 31, 2019 and December 31, 2018, the Company had not accrued a provision for uncertain tax positions. See Note 11 for further discussion related to income taxes.

Property and equipment is recorded at historical cost, net of accumulated depreciation, amortization and, if applicable, impairment charges. The Company reviews its property and equipment assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

Property and equipment are depreciated over the following useful lives (in years):

	Useful Lives
Computers and software		3
Laboratory equipment	3-6.5
Furniture	5-16.5
Manufacturing equipment		2

Leasehold improvements are amortized on a straight-line basis over the shorter of their estimated useful lives or lease terms. See Note 6 for further discussion regarding property and equipment.

The Company is a lessee in several noncancelable operating leases, primarily for office space, office equipment and vehicles. The Company currently has no finance leases.

The Company accounts for leases in accordance with ASC Topic 842, “Leases”. The Company determines if an arrangement is a lease at inception. Right-of-use (“ROU”) assets and operating lease liabilities are recognized based on the present value of lease payments over the lease term as of the commencement date. Operating lease ROU assets are presented as operating lease right of use assets on the condensed consolidated balance sheets. The current portion of operating lease liabilities is included in other current liabilities and the long-term portion is presented separately as operating lease liabilities on the condensed consolidated balance sheets.

Lease expense is recognized on a straight-line basis for operating leases. Variable lease payments associated with the Company’s leases are recognized when the event, activity, or circumstance in the lease agreement on which those payments are assessed occurs. Variable lease payments are presented as operating expense on the condensed consolidated statements of operations in the same line item as expense arising from fixed lease payments.

The Company’s lease terms may include options to extend the lease. The lease extensions are included in the measurement of the right of use asset and lease liability when it is reasonably certain that it will exercise that option.

Because most of the Company’s leases do not provide an implicit rate of return, an incremental borrowing rate is used based on the information available at the commencement date in determining the present value of lease payments on an individual lease basis. The Company’s incremental borrowing rate for a lease is the rate of interest it would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms.

The Company has lease agreements with lease and non-lease components. We applied the modified retrospective transition method and elected the transition option to use the effective date of January 1, 2019 as the date of initial application (“Transition Date”). Consequently, the disclosures required under Topic 842 are not provided for dates and periods before January 1, 2019.

Topic 842 provides a number of optional practical expedients in transition. The Company elected the ‘package of practical expedients’, which permits not to reassess under Topic 842 its prior conclusions about lease identification, lease classification, and initial direct costs. The Company did not elect the use-of-hindsight or the practical expedient pertaining to land easements; the latter not being applicable to the Company.

Topic 842 had a material impact on our condensed consolidated balance sheets, but did not have an impact on our condensed consolidated statements of operations. The most significant impact was the recognition of ROU assets and lease liabilities for operating leases.

ROU assets for operating leases are periodically reviewed for impairment losses under ASC 360-10, “Property, Plant, and Equipment”, to determine whether a ROU asset is impaired, and if so, the amount of the impairment loss to recognize.

The Company derives virtually all of its revenues from its license and supply agreement (the “Allergan Agreement”) with Allergan Pharmaceuticals International Limited (“Allergan”), a wholly owned subsidiary of Allergan plc. Under the Allergan Agreement, the Company grants Allergan an exclusive license to develop, commercialize, and otherwise exploit products that contain reverse thermally triggered hydrogel (“RTGel”) and agrees to supply Allergan with pre-clinical and clinical quantities of the RTGel product, also referred to as the RTGelvials. The Allergan Agreement contains up-front license fees, future supply fees, development, regulatory, and sales-based milestone payments, and sales-based royalty payments.

The Company determined that Allergan is its customer and the Allergan Agreement is in scope of ASC 606, which was adopted as of January 1, 2018. The Company adopted ASC 606 under the modified retrospective method, which did not have a material impact on the condensed consolidated statements of operations.

The Company recognizes revenue related to supply of RTGel at a point in time, upon delivery to Allergan. During the three months ended March 31, 2019 and 2018, the Company recognized $0 and $0.5 million of revenue related to RTGel supplied to Allergan, respectively.

Shipping and handling costs associated with supply of RTGel are accounted for as a fulfillment cost and are in included in cost of revenues.

General and administrative expenses consist primarily of salaries and other related costs, including share-based compensation, for personnel in executive, finance, accounting, legal, investor relations, facilities, business development and human resources functions. Other significant costs include facility costs not otherwise included in research and development expenses, legal fees relating to corporate matters, insurance, public company expenses relating to maintaining compliance with listing rules of the Nasdaq Stock Market and requirements of the U.S. Securities and Exchange Commission (“SEC”), insurance and investor relations costs, and fees for accounting and consulting services. General and administrative costs are expensed as incurred, and the Company accrues for services provided by third parties related to the above expenses by monitoring the status of services provided and receiving estimates from its service providers and adjusting its accruals as actual costs become known.

Research and development costs are expensed as incurred and consist primarily of the cost of salaries, share-based compensation expenses, payroll taxes and other employee benefits, subcontractors and materials used for research and development activities, including preclinical studies, clinical trials, manufacturing costs and professional services. The costs of services performed by others in connection with the research and development activities of an entity, including research and development conducted by others on behalf of the entity, shall be included in research and development costs and expensed as the contracted work is performed. The Company accrues for costs incurred as the services are being provided by monitoring the status of the trial or project and the invoices received from its external service providers. The Company adjusts its accrual as actual costs become known. Where contingent milestone payments are due to third parties under research and development arrangements or license agreements, the milestone payment obligations are expensed when the milestone results are achieved.

The costs of intangibles that are purchased from others for particular research and development projects and that have no alternative future uses (in other research and development projects or otherwise) and therefore no separate economic values are research and development costs at the time the costs are incurred.

Share-based compensation cost is measured at the grant date based on the fair value of the award and is recognized as expense over the required service period, which is equal to the vesting period. The fair value of options is determined using the Black-Scholes option-pricing model. The fair value of a restricted stock unit (“RSU”) equaled the closing price of our ordinary shares on the grant date.

As of December 31, 2016, the Company early adopted the policy to account for forfeitures as they occur according to the FASB’s Accounting Standards Update (“ASU”) 2016-09, Improvements to Employee Share-Based Payment Accounting.

The Company elected to recognize compensation costs for awards conditioned only on continued service that have a graded vesting schedule using the straight-line method and to value the awards based on the single-option award approach.

As of December 31, 2018, the Company adopted ASU 2018-07, Compensation-Stock Compensation, which establishes that the measurement of equity-classified nonemployee awards will be fixed at the grant date. The adoption of ASU 2018-07 did not have an impact on the condensed consolidated statements of operations.

Basic net loss per share is computed by dividing the net loss attributable to common shareholders by the weighted-average number of common shares outstanding. Diluted net loss per share is computed similarly to basic net loss per share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential common shares had been issued and if the additional common shares were dilutive.

For all periods presented, potentially dilutive securities are excluded from the computation of fully diluted loss per share as their effect is anti-dilutive.

In June 2018, the FASB issued ASU No. 2018-07, "Compensation-Stock Compensation" (“ASU 2018-07”) to improve the usefulness of information provided to users of financial statements while reducing cost and complexity in financial reporting and provide guidance aligning the measurement and classification for share-based payments to nonemployees with the guidance for share-based payments to employees. Under the guidance, the measurement of equity-classified nonemployee awards will be fixed at the grant date. This standard is effective for fiscal years beginning after December 15, 2018, and interim periods within those annual periods. The adoption of ASU 2018-07 did not have a material impact on the Company’s Consolidated Statements of Operations.

In February 2016, the FASB issued ASU No. 2016-02, “Leases” (“Topic 842”). Topic 842 supersedes existing guidance in Leases (“Topic 840”). Topic 842 was subsequently amended by ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU 2018-10, Codification Improvements to Topic 842, Leases; ASU No. 2018-11, Targeted Improvements; ASU 2018-20, Narrow-Scope Improvements for Lessors; and ASU 2019-01 – Leases. Topic 842 requires lessees to recognize ROU assets and lease liabilities on the balance sheet for leases with lease terms greater than twelve months, including those classified as operating leases. The Company adopted Topic 842 and related interpretations effective January 1, 2019 and recognized ROU assets and operating lease liabilities of $3.4 million.
