Houston American Energy Corp. &lt;font style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; font-style: italic;"&gt;et al&lt;/font&gt;., Case No. 4:12-CV-1332.&amp;#160; The complaint generally alleged that, between March 29, 2010 and April 18, 2012, all of the defendants violated Sections 10(b) of the Securities Exchange Act of 1934 and SEC Rule 10b-5 and the individual defendants violated Section 20(a) of the Exchange Act in making materially false and misleading statements including certain statements related to the status and viability of the Tamandua #1 well on the Company&amp;#8217;s CPO 4 prospect. Two additional class action lawsuits were filed against us in May 2012. The complaints sought unspecified damages, interest, attorneys&amp;#8217; fees, and other costs. On September 20, 2012, the court consolidated the class action lawsuits and appointed a lead plaintiff and, on November 15, 2012, the lead plaintiffs filed an amended complaint.&amp;#160; The amended complaint, among other things, expanded the putative class period to November 9, 2009 to April 18, 2012 and added allegations challenging a November 2009 estimate concerning the CPO 4 prospect.&amp;#160; On January 14, 2013, the Company filed a motion to dismiss and, on August 22, 2013, the court granted the motion and dismissed the complaint. The plaintiffs subsequently filed a Notice of Appeal of the dismissal of the complaint. On July 15, 2014, the U.S. Court of Appeals for the Fifth Circuit reversed the dismissal of the case. The appellate court ruling focused on the sufficiency of the pleadings in the case, made no determination regarding the merits of the factual allegations, and remanded the case to the District Court for further proceedings. In October 2014, the parties reached an agreement in principle to settle the consolidated lawsuit. The settlement, which provides for a $7,000,000 payment, is expected to be fully funded by the Company&amp;#8217;s insurance and was subject to preliminary and final approval of the court. The parties submitted the settlement to the court for approval on December 31, 2014.&amp;#160; The court signed an order on April 16, 2015 preliminarily approving the settlement and scheduled a final approval hearing on July 29, 2015.&amp;#160; Pursuant to the terms of the settlement, the Company, through its insurer, is required to escrow settlement funds in the amount of $7,000,000 by approximately May 15, 2015, The Compnay's insurer deposited the required funds into an escrow account&amp;#160;to fund&amp;#160; the settlement. If, for any reason, the settlement is not approved and consummated, we may be exposed to damages and costs in excess of our insurance which would have a material adverse effect on our financial position, results of operations or cash flows.&lt;/div&gt;&lt;div style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; text-align: left; text-indent: 24.5pt;"&gt;&amp;#160;&lt;/div&gt;&lt;div style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; text-align: left;"&gt;&lt;font style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; font-style: italic;"&gt;SEC Administrative Proceeding.&amp;#160; &lt;/font&gt;On August 4, 2014, following a multi-year investigation, the SEC instituted administrative cease-and-desist proceedings pursuant to Section 8A of the Securities Act of 1933 and 21C of the Securities Exchange Act of 1934, styled &lt;font style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; font-style: italic;"&gt;In the Matter of Houston American Energy Corp., John F. Terwilliger, Jr., Undiscovered Equities, Inc. and Kevin T. McKnight&lt;/font&gt;.&amp;#160; The administrative proceeding alleged that Mr. Terwilliger and, in turn, Houston American Energy, made false and misleading statements with respect to the CPO 4 prospect and promoted those statements through Undiscovered Equities and its principal, Kevin McKnight. The SEC was seeking a determination from an administrative law judge as to whether (i) the allegations of the SEC were true; (ii) Houston American Energy and Mr. Terwilliger should be ordered to (A) cease-and-desist from committing or causing violations of Section 10(b) of the Exchange Act and Rule 10b-5 thereunder, (B) pay a civil penalty pursuant to Section 8A(g) of the Securities Act and Section 21B(a) of the Exchange Act, and (C) pay disgorgement pursuant to Section 8A(e) of the Securities Act and Sections 21B(e) and 21C(e) of the Exchange Act; and (iii) Mr. Terwilliger should be prohibited from acting as an officer and director of a public company pursuant to Section 8A(f) of the Securities Act and Section 21C(f) of the Exchange Act.&lt;/div&gt;&lt;div style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; text-align: left; text-indent: 24.5pt;"&gt;&amp;#160;&lt;/div&gt;&lt;div style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; text-align: left;"&gt;At December 31, 2014, the administrative proceeding was pending and was scheduled for trial in January 2015.&amp;#160; The trial was stayed in January 2015 pending consideration by the Commission of a proposed settlement and remains pending. The settlement proposal remained pending at March 31, 2015.&amp;#160; On April 16, 2015, the Commission formally approved the settlement. Pursuant to the terms of the settlement, among other things, the Company agreed to pay a penalty of $400,000 and the Company&amp;#8217;s Chief Executive Officer resigned and agreed to pay a penalty of $150,000. The Company, at December&amp;#160;31, 2014, recorded on its balance sheet a contingent liability, and on its statement of operations a contingent loss of $400,000 relating to the settlement.&amp;#160; The Company has an insurance policy that insures for legal fees incurred in connection with the above administrative proceeding.&amp;#160; At December 31, 2014, the Company had recorded an insurance claim receivable of $1,612,681 for fees which have been incurred, but not yet reimbursed by its insurance company.&amp;#160; As of March 31, 2015, the insurance claim receivable relating to unpaid legal fees totaled $770,574.&lt;/div&gt;&lt;/div&gt;</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>

The Company&amp;#8217;s only outstanding potentially dilutive securities are options and warrants.

In preparing financial statements, management makes informed judgments and estimates that affect the reported amounts of assets and liabilities as of the date of the financial statements and affect the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, management reviews its estimates, including those related to such potential matters as litigation, environmental liabilities, income taxes and the related valuation allowance, determination of proved reserves of oil and gas and asset retirement obligations. Changes in facts and circumstances may result in revised estimates and actual results may differ from these estimates.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; font-style: italic; text-align: left;"&gt;Concentration of Credit Risk&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="font-size: 10pt; font-family: 'Times New Roman', Times, serif; text-align: left;"&gt;Financial instruments that potentially subject the Company to a concentration of credit risk include cash, cash equivalents and any marketable securities.

Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common shares were exercised or converted into common shares that then shared in the earnings of the Company. The Company&amp;#8217;s only outstanding potentially dilutive securities are options and warrants.
