Certain footnote disclosures normally&#13;included in financial statements prepared in accordance with accounting principles generally accepted in the United States (&amp;#8220;GAAP&amp;#8221;)&#13;have been condensed or omitted pursuant to Article 8 of Regulation S-X of the Securities and Exchange Commission (&amp;#8220;SEC&amp;#8221;)&#13;rules and regulations. Operating results for the three-month period ended March 31, 2020 are not necessarily indicative of results&#13;for the full year or any other future periods. As such, it is suggested that these condensed consolidated financial statements&#13;be read in conjunction with the consolidated financial statements and notes thereto included in the Company&amp;#8217;s Annual Report&#13;on Form&amp;#160;10-K for the period ended December 31, 2019.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;&lt;i&gt;Going Concern&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;Management believes the accompanying condensed consolidated financial&#13;statements have been prepared in conformity with GAAP, which contemplate continuation of the Company as a going concern. The Company&#13;has an accumulated deficit of $238,823,080 on March 31, 2020 and $236,168,436 on December 31, 2019 and used cash in operations of&#13;$2,671,029 and $2,132,811 during the three months ended March 31, 2020 and 2019, respectively. The Company requires substantial&#13;additional funds to complete clinical trials and pursue regulatory approvals. Management is actively seeking additional sources&#13;of equity and/or debt financing; however, there is no assurance that any additional funding will be available.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;In view of the matters described above, recoverability of a major&#13;portion of the recorded asset amounts shown in the accompanying March 31, 2020 balance sheet is dependent upon continued operations&#13;of the Company, which in turn is dependent upon the Company&amp;#8217;s ability to meet its financing requirements on a continuing&#13;basis, to maintain present financing, and to generate cash from future operations. These factors, among others, raise substantial&#13;doubt about the Company&amp;#8217;s ability to continue as a going concern. The condensed consolidated financial statements do not&#13;include any adjustments relating to the recoverability and classification of recorded asset amounts or amounts and classification&#13;of liabilities that might be necessary should the Company be unable to continue in existence.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;&lt;i&gt;Use of Estimates&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;In preparing the unaudited condensed consolidated financial statements,&#13;management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure&#13;of contingent assets and liabilities at the dates of the unaudited condensed consolidated financial statements and the reported&#13;amounts of revenue and expenses during the reporting periods. Actual results could differ from these estimates and the operating&#13;results for the interim periods presented are not necessarily indicative of the results expected for the full year.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;On an ongoing basis, management reviews its estimates to ensure that&#13;these estimates appropriately reflect changes in the Company&amp;#8217;s business and new information as it becomes available. If historical&#13;experience and other factors used by management to make these estimates do not reasonably reflect future activity, the Company&amp;#8217;s&#13;results of operations and financial position could be materially impacted.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;&lt;i&gt;Principles of Consolidation&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;The accompanying condensed consolidated financial statements include&#13;the accounts and transactions of the Company and Life Newco.

The Company used $2.7 million of cash for operating&#13;activities during the three months ended March 31, 2020 and had stockholders&amp;#8217; equity of $3.4 million, versus $3.8 million&#13;on December 31, 2019.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;The Company expects to continue to incur expenses related to development&#13;of levosimendan for pulmonary hypertension and other potential indications, as well as identifying and developing other potential&#13;product candidates. Based on its resources at March 31,2020, the Company believes that it has sufficient capital to fund its planned&#13;operations through the third quarter of calendar year 2020. However, the Company will need substantial additional financing in&#13;order to fund its operations beyond such period and thereafter until it can achieve profitability, if ever. The Company depends&#13;on its ability to raise additional funds through various potential sources, such as equity and debt financing, or to license its&#13;product candidates to another pharmaceutical company. The Company will continue to fund operations from cash on hand and through&#13;sources of capital similar to those previously described. The Company cannot assure that it will be able to secure such additional&#13;financing, or if available, that it will be sufficient to meet its needs.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;The continued spread of COVID-19 globally could adversely affect&#13;the Company's ability to retain principal investigators and site staff who, as healthcare providers, may have heightened exposure&#13;to COVID-19 if an outbreak occurs in their geography. Further, some of these investigators and site staff may be unable to comply&#13;with clinical trial protocols if quarantines or travel restrictions impede movement or interrupt healthcare services, or if they&#13;become infected with COVID-19 themselves, which would delay the Company&amp;#8217;s ability to complete its phase 2 clinical trial&#13;or release clinical trial results.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;To the extent that the Company raises additional funds by issuing&#13;shares of its common stock or other securities convertible or exchangeable for shares of common stock, stockholders will experience&#13;dilution, which may be significant. In the event the Company raises additional capital through debt financings, the Company may&#13;incur significant interest expense and become subject to covenants in the related transaction documentation that may affect the&#13;manner in which the Company conducts its business. To the extent that the Company raises additional funds through collaboration&#13;and licensing arrangements, it may be necessary to relinquish some rights to its technologies or product candidates or grant licenses&#13;on terms that may not be favorable to the Company.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;Any or all of the foregoing may have a material adverse effect on&#13;the Company&amp;#8217;s business and financial performance.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;&lt;i&gt;Net Loss per Share&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;Basic net loss per share, which excludes antidilutive securities,&#13;is computed by dividing net loss by the weighted-average number of common shares outstanding for that particular period. In contrast,&#13;diluted net loss per share considers the potential dilution that could occur from other equity instruments that would increase&#13;the total number of outstanding shares of common stock. Such amounts include shares potentially issuable under outstanding options,&#13;restricted stock and warrants.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;The following outstanding options, warrants and restricted stock&#13;were excluded from the computation of basic and diluted net loss per share for the periods presented because including them would&#13;have had an anti-dilutive effect.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;table cellspacing="0" cellpadding="0" style="font: 12pt Times New Roman, Times, Serif; width: 100%"&gt;&#13;&lt;tr style="vertical-align: bottom"&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td colspan="6" style="text-align: center"&gt;&lt;font style="font-size: 8pt"&gt;&lt;b&gt;Three months ended March 31,&lt;/b&gt;&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr style="vertical-align: bottom"&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="padding-bottom: 1.5pt"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td colspan="2" style="border-bottom: black 1pt solid; text-align: center"&gt;&lt;font style="font-size: 8pt"&gt;&lt;b&gt;2020&lt;/b&gt;&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="padding-bottom: 1.5pt"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="padding-bottom: 1.5pt"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td colspan="2" style="border-bottom: black 1pt solid; text-align: center"&gt;&lt;font style="font-size: 8pt"&gt;&lt;b&gt;2019&lt;/b&gt;&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="padding-bottom: 1.5pt"&gt;&amp;#160;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr style="vertical-align: bottom"&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td colspan="2" style="text-align: center"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td colspan="2" style="text-align: center"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr style="vertical-align: bottom"&gt;&#13;    &lt;td style="width: 75%"&gt;&lt;font style="font-size: 8pt"&gt;Warrants to purchase common stock&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="width: 1%"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="width: 1%"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="width: 9%; text-align: right"&gt;&lt;font style="font-size: 8pt"&gt;14,362,007&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="width: 1%"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="width: 1%"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="width: 1%"&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="width: 9%; text-align: right"&gt;&lt;font style="font-size: 8pt"&gt;10,640,718&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="width: 2%"&gt;&amp;#160;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr style="vertical-align: bottom"&gt;&#13;    &lt;td&gt;&lt;font style="font-size: 8pt"&gt;Options to purchase common stock&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="text-align: right"&gt;&lt;font style="font-size: 8pt"&gt;581,694&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="text-align: right"&gt;&lt;font style="font-size: 8pt"&gt;241,735&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr style="vertical-align: bottom"&gt;&#13;    &lt;td&gt;&lt;font style="font-size: 8pt"&gt;Convertible preferred shares outstanding&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="text-align: right"&gt;&lt;font style="font-size: 8pt"&gt;210&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&#13;    &lt;td style="text-align: right"&gt;&lt;font style="font-size: 8pt"&gt;554,603&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td&gt;&amp;#160;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;/table&gt;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;&lt;i&gt;Leases&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;The Company determines if an arrangement includes a lease at inception.&#13;Operating leases are included in operating lease right-of-use assets, other current liabilities, and long-term lease liabilities&#13;in the Company&amp;#8217;s condensed consolidated balance sheets. Right-of-use assets represent the Company&amp;#8217;s right to use an&#13;underlying asset for the lease term and lease liabilities represent the Company&amp;#8217;s obligation to make lease payments arising&#13;from the lease. Operating lease right-of-use assets and liabilities are recognized at the lease commencement date based on the&#13;present value of lease payments over the lease term. In determining the net present value of lease payments, the Company uses the&#13;incremental borrowing rate based on the information available at the lease commencement date. The operating lease right-of-use&#13;assets also include any lease payments made and exclude lease incentives. The Company&amp;#8217;s leases may include options to extend&#13;or terminate the lease which are included in the lease term when it is reasonably certain that the Company will exercise any such&#13;option. Lease expense is recognized on a straight-line basis over the expected lease term. The Company has elected to account for&#13;leases with an initial term of 12 months or less similar to previous guidance for operating leases, under which the Company will&#13;recognize those lease payments in the consolidated statements of operations and comprehensive loss on a straight-line basis over&#13;the lease term.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;&lt;i&gt;Recent Accounting Pronouncements&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;In December 2019, the Financial Accounting Standards Board (&amp;#8220;FASB&amp;#8221;)&#13;issued an accounting standard intended to simplify accounting for income taxes. It removes certain exceptions to the general principles&#13;in Topic 740, Income Taxes and amends existing guidance to improve consistent application. This guidance is effective for fiscal&#13;years, and interim periods within those fiscal years, beginning after December 15, 2020 and early adoption is permitted. The Company&#13;is currently evaluating this standard, but it does not believe the adoption of the new guidance will have a material impact on&#13;its consolidated financial statements.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;In June 2016, the FASB issued an accounting standard that amends&#13;how credit losses are measured and reported for certain financial instruments that are not accounted for at fair value through&#13;net income. This standard requires that credit losses be presented as an allowance rather than as a write-down for available-for-sale&#13;debt securities and will be effective for interim and annual reporting periods beginning January&amp;#160;1, 2023, with early adoption&#13;permitted. A modified retrospective approach is to be used for certain parts of this guidance, while other parts of the guidance&#13;are to be applied using a prospective approach. The Company does not believe the adoption of this standard will have a material&#13;impact on its consolidated financial statements and related disclosures.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;</us-gaap:SignificantAccountingPoliciesTextBlock>

The Company considers the carrying amount of its cash and cash equivalents to approximate fair value due to&#13;the short-term nature of these instruments.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;Accounting for fair value measurements involves a single definition&#13;of fair value, along with a conceptual framework to measure fair value, with a fair value defined as &amp;#8220;the price that would&#13;be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement&#13;date.&amp;#8221; The fair value measurement hierarchy consists of three levels:&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;table cellspacing="0" cellpadding="0" style="width: 100%"&gt;&#13;&lt;tr style="vertical-align: top"&gt;&#13;    &lt;td style="font: 12pt Times New Roman, Times, Serif; width: 20%"&gt;&lt;font style="font-size: 8pt"&gt;Level one&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="width: 80%"&gt;&#13;        &lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;Quoted market prices in active markets for identical assets or liabilities;&lt;/p&gt;&#13;        &lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr style="vertical-align: top"&gt;&#13;    &lt;td style="font: 12pt Times New Roman, Times, Serif"&gt;&lt;font style="font-size: 8pt"&gt;Level two&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td&gt;&#13;        &lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;Inputs other than level one inputs that are either directly or indirectly&#13;        observable; and&lt;/p&gt;&#13;        &lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;tr style="vertical-align: top"&gt;&#13;    &lt;td style="font: 12pt Times New Roman, Times, Serif"&gt;&lt;font style="font-size: 8pt"&gt;Level three&lt;/font&gt;&lt;/td&gt;&#13;    &lt;td style="font: 12pt Times New Roman, Times, Serif"&gt;&lt;font style="font-size: 8pt"&gt;Unobservable inputs developed using estimates and assumptions, which are developed by the reporting entity and reflect those assumptions that a market participant would use.&lt;/font&gt;&lt;/td&gt;&lt;/tr&gt;&#13;&lt;/table&gt;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;The Company applies valuation techniques that (1)&amp;#160;place greater&#13;reliance on observable inputs and less reliance on unobservable inputs and (2)&amp;#160;are consistent with the market approach, the&#13;income approach and/or the cost approach, and include enhanced disclosures of fair value measurements in the Company&amp;#8217;s condensed&#13;consolidated financial statements.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;b&gt;&lt;i&gt;Investments in Marketable Securities&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;The Company classifies all of its investments as available-for-sale.&#13;Unrealized gains and losses on investments are recognized in comprehensive income/(loss), unless an unrealized loss is considered&#13;to be other than temporary, in which case the unrealized loss is charged to operations. The Company periodically reviews its investments&#13;for other than temporary declines in fair value below cost basis and whenever events or changes in circumstances indicate that&#13;the carrying amount of an asset may not be recoverable. The Company believes the individual unrealized losses represent temporary&#13;declines primarily resulting from interest rate changes. Realized gains and losses are reflected in other income in the condensed&#13;consolidated statements of comprehensive loss and are determined using the specific identification method with transactions recorded&#13;on a settlement date basis. Investments with original maturities at date of purchase beyond three months and which mature at or&#13;less than 12 months from the balance sheet date are classified as current. Investments with a maturity beyond 12 months from the&#13;balance sheet date are classified as long-term. As of March 31, 2020, the Company believes that the costs of its investments are&#13;recoverable in all material respects.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;The following table summarizes the fair value of the Company&amp;#8217;s&#13;investments by type. The estimated fair value of the Company&amp;#8217;s fixed income investments is classified as Level 2 in the fair&#13;value hierarchy as defined in GAAP. These fair values are obtained from independent pricing services which utilize Level 2 inputs:&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;table cellspacing="0" cellpadding="0" style="font: 12pt Times New Roman, Times, Serif;

Under the 1999 Plan, with the approval of the Compensation Committee&#13;of the Board of Directors, the Company could grant stock options, restricted stock, stock appreciation rights and new shares of&#13;common stock upon exercise of stock options. On March 13, 2014, the Company&amp;#8217;s stockholders approved an amendment to the 1999&#13;Plan which increased the number of shares of common stock authorized for issuance under the 1999 Plan to a total of 200,000 shares,&#13;up from 15,000 previously authorized. On September 15, 2015, the Company&amp;#8217;s stockholders approved an additional amendment&#13;to the 1999 Plan which increased the number of shares of common stock authorized for issuance under the 1999 Plan to a total of&#13;250,000 shares, up from 200,000 previously authorized. The 1999 Plan expired on June 17, 2018 and no new grants may be made under&#13;that plan after that date. However, unexpired awards granted under the 1999 Plan remain outstanding and subject to the terms of&#13;the 1999 Plan.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;i&gt;1999 Plan Stock Options&lt;/i&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;Stock options granted under the 1999 Plan may be either ISOs or NSOs.&#13;ISOs could be granted only to employees.

The loan in the principal amount&#13;of $244,657 (the &amp;#8220;PPP Loan&amp;#8221;) was disbursed by First Horizon Bank (the &amp;#8220;Lender&amp;#8221;) pursuant to a promissory&#13;note issued by the Company (the &amp;#8220;Note&amp;#8221;).&lt;/font&gt;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&lt;font style="background-color: white"&gt;&amp;#160;The Note has a two-year&#13;term and bears interest at a fixed rate of 1.00% per annum. Monthly principal and interest payments, less the amount of any potential&#13;forgiveness, will commence on December 30, 2020. The Company did not provide any collateral or guarantees for the PPP Loan, nor&#13;did the Company pay any facility charge to obtain the PPP Loan. The Note provides for customary events of default, including, among&#13;others, those relating to failure to make payment, bankruptcy, breaches of representations, and material adverse effects. The Company&#13;may prepay the principal of the PPP Loan at any time, subject to certain notice requirements&lt;/font&gt;.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;Under the CARES Act, loan forgiveness is available for the sum of&#13;documented payroll costs, covered rent payments, and covered utilities during the eight-week period beginning on the approval date&#13;of the PPP Loan. For purposes of the CARES Act, payroll costs exclude compensation of an individual employee in excess of $100,000,&#13;prorated annually. Not more than 25% of the forgiven amount may be for non-payroll costs. Although the Company currently believes&#13;that its use of the PPP Loan will meet the conditions for forgiveness of the loan, the Company cannot assure that the PPP Loan&#13;will be forgiven, in whole or in part.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;</us-gaap:ScheduleOfSubsequentEventsTextBlock>

Right-of-use assets represent the Company&amp;#8217;s right to use an&#13;underlying asset for the lease term and lease liabilities represent the Company&amp;#8217;s obligation to make lease payments arising&#13;from the lease. Operating lease right-of-use assets and liabilities are recognized at the lease commencement date based on the&#13;present value of lease payments over the lease term. In determining the net present value of lease payments, the Company uses the&#13;incremental borrowing rate based on the information available at the lease commencement date. The operating lease right-of-use&#13;assets also include any lease payments made and exclude lease incentives. The Company&amp;#8217;s leases may include options to extend&#13;or terminate the lease which are included in the lease term when it is reasonably certain that the Company will exercise any such&#13;option. Lease expense is recognized on a straight-line basis over the expected lease term. The Company has elected to account for&#13;leases with an initial term of 12 months or less similar to previous guidance for operating leases, under which the Company will&#13;recognize those lease payments in the consolidated statements of operations and comprehensive loss on a straight-line basis over&#13;the lease term.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;</us-gaap:LesseeLeasesPolicyTextBlock>

It removes certain exceptions to the general principles&#13;in Topic 740, Income Taxes and amends existing guidance to improve consistent application. This guidance is effective for fiscal&#13;years, and interim periods within those fiscal years, beginning after December 15, 2020 and early adoption is permitted. The Company&#13;is currently evaluating this standard, but it does not believe the adoption of the new guidance will have a material impact on&#13;its consolidated financial statements.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;In June 2016, the FASB issued an accounting standard that amends&#13;how credit losses are measured and reported for certain financial instruments that are not accounted for at fair value through&#13;net income. This standard requires that credit losses be presented as an allowance rather than as a write-down for available-for-sale&#13;debt securities and will be effective for interim and annual reporting periods beginning January&amp;#160;1, 2023, with early adoption&#13;permitted. A modified retrospective approach is to be used for certain parts of this guidance, while other parts of the guidance&#13;are to be applied using a prospective approach. The Company does not believe the adoption of this standard will have a material&#13;impact on its consolidated financial statements and related disclosures.&lt;/p&gt;&#13;&#13;&lt;p style="font: 8pt Times New Roman, Times, Serif; margin: 0"&gt;&amp;#160;&lt;/p&gt;</us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock>
