In connection with that announcement, the Company discontinued the discovery efforts on its remaining preclinical programs: MM-401, an agonistic antibody targeting a novel immuno-oncology target, TNFR2; and MM-201, a highly stabilized agonist-Fc fusion protein targeting death receptors 4 and 5. The Company is seeking potential acquirers for its remaining preclinical and clinical assets.&lt;/p&gt;

(the &amp;#8220;Buyer&amp;#8221;), pursuant to which the Buyer agreed to purchase certain assets (the &amp;#8220;Transferred Assets&amp;#8221;) relating to certain of the Company&amp;#8217;s preclinical nanoliposome programs (the &amp;#8220;Transaction&amp;#8221;). The Company and the Buyer completed the Transaction simultaneously with the execution of the Asset Purchase Agreement. Under the terms of the Asset Purchase Agreement, the Buyer paid to the Company a cash payment of &lt;/font&gt;&lt;font style="color:#000000;"&gt;$2.3 &lt;/font&gt;&lt;font style="Background-color:#FFFFFF;"&gt;million and reimbursed the Company for &lt;/font&gt;&lt;font style="color:#000000;"&gt;$0.2 million &lt;/font&gt;&lt;font style="Background-color:#FFFFFF;"&gt;related to certain specified expenses. The Company incurred $0.4 million expenses related to the Transaction as of March 31, 2020.&lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;The Company is subject to risks and uncertainties common to companies in the biopharmaceutical industry, including, among other things, development by competitors of new technological innovations, protection of proprietary technology and compliance with government regulations, approval by the FDA and other foreign health agencies to approve any pharmaceutical under development, obtaining insurance reimbursement for any drug if and when approved by regulators, and its ability to secure additional capital to fund operations. None of the Company&amp;#8217;s product candidates are approved for any indication by the FDA or any other regulatory agency. The Company operates in an environment of rapid change in technology and substantial competition from pharmaceutical and biotechnology companies, among others. In addition, the Company is dependent upon the services of its external consultants for the operation of the Company. The Company&amp;#8217;s business strategy depends substantially upon its ability to receive future milestone payments from Ipsen and Elevation. Any failure to achieve such milestones or a perception that the milestones may not be achieved will materially and adversely affect the Company and the value of its common stock.&lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;color:#212529;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;The recent COVID-19 outbreak has created significant volatility and economic disruption and the impact on&amp;#160;the Company&amp;#8217;s &lt;font style="color:#000000;"&gt;future consolidated results of operations is uncertain&lt;/font&gt;. See &amp;#8220;Management&amp;#8217;s Discussion and Analysis of Financial Condition and Results of Operations - COVID 19 Update&amp;#8221; and &amp;#8220;Risk Factors&amp;#8221; for further information regarding the impact of the COVID-19 pandemic on the Company&amp;#8217;s business and financial condition.&lt;/p&gt;

As of March&amp;#160;31, 2020, the Company had an accumulated deficit of $540.4 million.&amp;#160;During three months ended March&amp;#160;31, 2020, the Company incurred net income of $0.2 million and used $1.0 million of cash in operating activities.&amp;#160;The Company expects to continue to generate operating losses for the foreseeable future. The Company expects that its cash and cash equivalents of $18.0 million at March&amp;#160;31, 2020 &lt;font style="color:#000000;"&gt;will allow the Company to continue its operations into 2027, when the Company estimates the longest-term potential Ipsen milestone may be achieved. The continued viability of the Company beyond that point is dependent on its ability to realize milestone payments from its licensed product candidates, raise additional capital to finance its operations or to reduce operating expenses. There can be no assurance that the Company will be successful in receiving future milestone payments or able to obtain sufficient capital to cover its costs on acceptable terms, if at all.&lt;/font&gt;&lt;/p&gt;
&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;The Company expects that it would seek to finance any future cash needs through a combination of divestitures of its product candidates or other assets, equity offerings and debt financings. There can be no assurance as to the timing, terms or consummation of any divestiture or financing, and the terms of any such financing may adversely affect the holdings or the rights of the Company&amp;#8217;s stockholders or require the Company to relinquish rights to certain of its revenue streams or product candidates. &lt;/p&gt;</us-gaap:NatureOfOperations>

&lt;p style="margin-top:12pt;margin-bottom:0pt;text-indent:4.54%;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;"&gt;Diluted net income (loss) per share is computed by dividing the net income (loss) attributable to Merrimack Pharmaceuticals, Inc. by the weighted-average number of dilutive common shares outstanding during the period. Dilutive shares outstanding is calculated by adding to the weighted shares outstanding any potential (unissued) shares of common stock from outstanding stock options based on the treasury stock method. Outstanding stock options were not included in the diluted net income (loss) per share calculation because the options were out of the money or to do so would have been antidilutive (i.e., the total proceeds upon exercise would have exceeded the market value of the underlying common shares). In a period when a net loss is reported, all common stock equivalents are excluded from the calculation because they would have an anti-dilutive effect, meaning the loss per share would be reduced. Therefore, in periods where a loss is reported, there is no difference in basic and dilutive loss per share.&lt;/p&gt;

Outstanding options excluded from the calculation of diluted income (loss) per share for the three months ended March&amp;#160;31, 2020 and 2019 are shown in the chart below:&lt;/p&gt;

Specifically, this guidance will require entities to utilize a new &amp;#8220;expected loss&amp;#8221; model as it relates to trade and other receivables. In addition, entities will be required to recognize an allowance for estimated credit losses on available-for-sale debt securities, regardless of the length of time that a security has been in an unrealized loss position. This guidance will be effective for annual reporting periods beginning after December 15, 2019, including interim periods within those annual reporting periods, and early adoption is permitted. The new guidance was adopted on January&amp;#160;1, 2020 and it did not have a material impact on the Company&amp;#8217;s condensed consolidated financial statements.&lt;/p&gt;

This standard eliminates, adds and modifies certain disclosure requirements for fair value measurements as part of its disclosure framework project. ASU 2018-13 is effective for annual reporting periods beginning after December 15, 2019 and interim periods within those annual periods and early adoption is permitted. The new guidance was adopted on January&amp;#160;1, 2020 and it did not have a material impact on the Company&amp;#8217;s condensed consolidated financial statements.&lt;/p&gt;

Specifically, this guidance will require entities to utilize a new &amp;#8220;expected loss&amp;#8221; model as it relates to trade and other receivables. In addition, entities will be required to recognize an allowance for estimated credit losses on available-for-sale debt securities, regardless of the length of time that a security has been in an unrealized loss position. This guidance will be effective for annual reporting periods beginning after December 15, 2019, including interim periods within those annual reporting periods, and early adoption is permitted. The new guidance was adopted on January&amp;#160;1, 2020 and it did not have a material impact on the Company&amp;#8217;s condensed consolidated financial statements.&lt;/p&gt;
