At times, the Company has cash, cash equivalents, and investment securities at financial institutions exceeding the Federal Depository Insurance Company (“FDIC”) and the Securities Investor Protection Corporation (“SIPC”) insured limit on domestic currency and the Netherlands FDIC counterpart for foreign currency.

As of December 31, 2020 2019 not December 31, 2020 2019 Accounts Receivable Accounts receivable consist of billed receivables currently due from customers and unbilled receivables. Unbilled receivables represent the excess of contract revenue (or amounts reimbursable under contracts) over billings to date. Such amounts become billable in accordance with the contract terms, which usually consider the passage of time, achievement of certain milestones or completion of the project. Outstanding account balances are reviewed individually for collectability.

The Company believes that the cost-based input method is the best measure of progress to reflect how the Company transfers its performance obligation to a customer. In applying the cost-based input method of revenue recognition, the Company uses actual costs incurred relative to budgeted costs to fulfill the performance obligation. These costs consist primarily of full-time equivalent effort and third A cost-based input method of revenue recognition requires management to make estimates of costs to complete the Company’s performance obligations. In making such estimates, significant judgment is required to evaluate assumptions related to cost estimates. The cumulative effect of revisions to estimated costs to complete the Company’s performance obligations will be recorded in the period in which changes are identified and amounts can be reasonably estimated. A significant change in these assumptions and estimates could have a material impact on the timing and amount of revenue recognized in future periods.

R&D costs are related to the Company’s internally funded pharmaceutical programs and other governmental and commercial projects. Research and development costs consist of personnel-related costs, facilities, research-related overhead, services from independent contract research organizations, and other external costs.

If an anticipated contract cost exceeds anticipated contract revenue, a provision for the entire estimated loss on the contract is recorded and then accreted into the statement of operations over the remaining term of the contract. The provision for contract losses is based on judgment and estimates, including revenues and costs, where applicable, the consideration of our business partners’ reimbursement, and when such loss is deemed probable to occur and is reasonable to estimate. Foreign Currency Transaction Gain or Loss The Company and its foreign subsidiary use the U.S. dollar as its functional currency, and initially measure the foreign currency denominated assets and liabilities at the transaction date. Monetary assets and liabilities are then re-measured at exchange rates in effect at the end of each period, and property and non-monetary assets and liabilities are converted at historical rates. Fair Value Measurements The Company applies fair value accounting for certain financial instruments that are recognized or disclosed at fair value in the financial statements. The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three • Level 1 • Level 2 • Level 3 The Company’s financial instruments included cash and cash equivalents, investment in debt securities, accounts receivable, accounts payable and accrued expenses, accrued payroll and related liabilities, deferred research and development obligations and deposits. The carrying amount of these financial instruments, except for investment in debt securities, approximates fair value due to the short-term maturities of these instruments. The Company’s short-term and long-term investments in debt securities are recorded at amortized cost, and their estimated fair value amounts are provided by the third Non-Marketable Investments The Company also holds investments in non-marketable equity securities of privately-held companies, which usually do not may may may no may not may may not may not For the year ended December 31, 2020, third December 31, 2020, $284,709. Income Taxes The Company accounts for income taxes under the asset and liability method in accordance with ASC Topic 740, not not In determining taxable income for the Company’s consolidated financial statements, we are required to estimate income taxes in each of the jurisdictions in which we operate. This process requires the Company to make certain estimates of our actual current tax exposure and assessment of temporary differences between the tax and financial statement recognition of revenue and expense. In evaluating the Company’s ability to recover its deferred tax assets, the Company must consider all available positive and negative evidence including its past operating results, the existence of cumulative losses in the most recent years and its forecast of future taxable income. Significant management judgment is required in determining our provision for income taxes, deferred tax assets and liabilities and any valuation allowance recorded against our net deferred tax assets. The Company is required to evaluate the provisions of ASC 740 740 not not 740. Comprehensive Income (Loss) Comprehensive income (loss) includes net income (loss) and other revenue, expenses, gains and losses that are recorded as an element of shareholders’ equity but are excluded from net income (loss) under U.S. GAAP. The Company does not not Stock-Based Compensation We recognize all share-based payments to employees, consultants, and our Board of Directors (the “Board”), as non-cash compensation expense, in research and development expenses or general and administrative expenses in the consolidated statement of operations based on the grant date fair values of such payments. Stock-based compensation expense recognized each period is based on the value of the portion of share-based payment awards that is ultimately expected to vest during the period. Forfeitures are recorded as they occur. For performance-based awards, the Company recognizes related stock-based compensation expense based upon its determination of the potential likelihood of achievement of the specified performance conditions at each reporting date. Net Loss Per Share Basic net loss per share is computed by dividing net loss available to common shareholders by the weighted average number of common shares outstanding during the reporting period. Diluted net loss per share adjusts the weighted average number of common shares outstanding for the potential dilution that could occur if common stock equivalents, such as stock options, warrants, restricted stock and convertible debt, were exercised and converted into common stock, calculated by applying the treasury stock method.

In making such estimates, significant judgment is required to evaluate assumptions related to cost estimates.
