The Company generated revenues of only &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$0.8&lt;/div&gt; million and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$0.7&lt;/div&gt; million during the years ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April 30, 2017 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2016,&lt;/div&gt; respectively. Based on the Company&amp;#x2019;s cash and cash equivalents and marketable securities balances as of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April 30, 2017, &lt;/div&gt;and including the proceeds received from our &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 2017 &lt;/div&gt;financing transaction in which we received aggregate net proceeds to us of approximately &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$7.2&lt;/div&gt; million, the Company believes that it will be able to finance its capital requirements and operations into the quarter ending &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; July 31, 2018. &lt;/div&gt;The Company will require additional equity and/or debt financing to continue its operations. The Company cannot provide assurances that it will be able to secure additional funding when needed or at all, or, if secured, that such funding would be on favorable terms.

The consolidated financial statements do &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; include any adjustments relating to the recoverability and classification of recorded assets amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty.&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 22.5pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;Management is evaluating different strategies to obtain the required additional funding for future operations. These strategies &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;include, but are &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; limited to, additional funding from current or new investors, officers and directors; borrowings of debt; a public offering of the Company&amp;#x2019;s equity or debt securities; partnerships and/or collaborations. There can be &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;no&lt;/div&gt; assurance that any of these future-funding efforts will be successful.&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 22.5pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;&lt;div style=" MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;In fiscal &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2017&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2016,&lt;/div&gt; the Company has continued to make investments in ongoing product development efforts in anticipation of future growth. The Company&amp;#x2019;s future results of operations involve significant risks and uncertainties. Factors that could affect the Company&amp;#x2019;s future operating results and cause actual results to vary materially from expectations include, but are &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; limited to, risks from lack of available financing and insufficient capital, performance of PowerBuoys, its inability to market and commercialize its PowerBuoys, technology development, scalability of technology and production, dependence on skills of key personnel, concentration of customers and suppliers, deployment risks and laws, regulations and permitting In order to continue to implement its business strategy, the Company requires additional equity and/or debt financing. The Company closed &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;four&lt;/div&gt; equity financing arrangements during the year ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April 30, 2017 &lt;/div&gt;and subsequently on &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 2, 2017. &lt;/div&gt;&lt;/div&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;The Company does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; currently have any committed sources of debt or equity financing, and the Company cannot assure that additional equity and/or debt financing will be available to the Company as needed on acceptable terms, or at all. Historically, the Company has raised capital through securities sales in the public capital markets. If sufficient additional financing is &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; obtained when needed, the Company &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;be required to further curtail or limit operations, product development costs, and/or selling, general and administrative activities in order to reduce its cash expenditures. This could cause the Company to be unable to execute its business plan, take advantage of future opportunities and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;cause it to scale back, delay or eliminate some or all of its product development activities and/or reduce the scope of or cease its operations.&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;Historically, the Company has funded its operations principally through public and private sales of our equity.

The Company has designed and continues to develop the PowerBuoy product line which is based on modular, ocean-going buoys, which the Company has been periodically ocean testing since &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;1997.&lt;/div&gt; The Company markets its PowerBuoys in the United States and internationally.&lt;/div&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt; Since fiscal &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2002,&lt;/div&gt; government agencies have accounted for a significant portion of the Company&amp;#x2019;s revenues.&amp;nbsp;These revenues were largely for the support of product development efforts.

(the &amp;#x201c;Company&amp;#x201d;) was founded in &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;1984&lt;/div&gt; in New Jersey, commenced business operations in &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;1994&lt;/div&gt; and re-incorporated in Delaware in &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2007.&lt;/div&gt; The Company is developing and commercializing its proprietary systems that generate electricity by harnessing the renewable energy of ocean waves. The Company uses proprietary technologies that convert the mechanical energy created by the heaving motion of ocean waves into electricity. The Company has designed and continues to develop the PowerBuoy product line which is based on modular, ocean-going buoys, which the Company has been periodically ocean testing since &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;1997.&lt;/div&gt; The Company markets its PowerBuoys in the United States and internationally.&lt;/div&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt; Since fiscal &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2002,&lt;/div&gt; government agencies have accounted for a significant portion of the Company&amp;#x2019;s revenues.&amp;nbsp;These revenues were largely for the support of product development efforts. The Company&amp;#x2019;s goal is that an increased portion of its revenues be from the sale or lease of products and maintenance services, as compared to revenue to support its product development efforts. As the Company continues to advance its proprietary technologies, it expects to continue to have a net decrease in cash from operating activities unless and until it achieves positive cash flow from the planned commercialization of its products and services.&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 21.6pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;table style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif; WIDTH: 100%; TEXT-INDENT: 0px;" cellspacing="0" cellpadding="0" border="0"&gt;  &lt;tr&gt; &lt;td style="WIDTH: 9pt; VERTICAL-ALIGN: middle"&gt; &lt;div style=" TEXT-ALIGN: left; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;&lt;/td&gt; &lt;td style="WIDTH: 18pt; VERTICAL-ALIGN: top"&gt; &lt;div style=" TEXT-ALIGN: left; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;(b)&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/td&gt; &lt;td style="VERTICAL-ALIGN: top"&gt; &lt;div style=" TEXT-ALIGN: left; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;Liquidity/Going Concern&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/td&gt; &lt;/tr&gt;  &lt;/table&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 21.6pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;Our consolidated financial statements have been prepared assuming the Company will continue as a going concern. The Company has experienced substantial and recurring losses from operations, which have contributed to an accumulated deficit of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$187.4&lt;/div&gt; million at &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April 30, 2017. &lt;/div&gt;At &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April 30, 2017, &lt;/div&gt;the Company had approximately &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$8.4&lt;/div&gt; million in cash on hand. The Company generated revenues of only &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$0.8&lt;/div&gt; million and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$0.7&lt;/div&gt; million during the years ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April 30, 2017 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2016,&lt;/div&gt; respectively. Based on the Company&amp;#x2019;s cash and cash equivalents and marketable securities balances as of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April 30, 2017, &lt;/div&gt;and including the proceeds received from our &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 2017 &lt;/div&gt;financing transaction in which we received aggregate net proceeds to us of approximately &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$7.2&lt;/div&gt; million, the Company believes that it will be able to finance its capital requirements and operations into the quarter ending &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; July 31, 2018. &lt;/div&gt;The Company will require additional equity and/or debt financing to continue its operations. The Company cannot provide assurances that it will be able to secure additional funding when needed or at all, or, if secured, that such funding would be on favorable terms. These factors raise substantial doubt about the Company&amp;#x2019;s ability to continue as a going concern.&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 22.5pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;The consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The consolidated financial statements do &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; include any adjustments relating to the recoverability and classification of recorded assets amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty.&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 22.5pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;Management is evaluating different strategies to obtain the required additional funding for future operations. These strategies &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;include, but are &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; limited to, additional funding from current or new investors, officers and directors; borrowings of debt; a public offering of the Company&amp;#x2019;s equity or debt securities; partnerships and/or collaborations. There can be &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;no&lt;/div&gt; assurance that any of these future-funding efforts will be successful.&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 22.5pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;&lt;div style=" MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;In fiscal &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2017&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2016,&lt;/div&gt; the Company has continued to make investments in ongoing product development efforts in anticipation of future growth. The Company&amp;#x2019;s future results of operations involve significant risks and uncertainties. Factors that could affect the Company&amp;#x2019;s future operating results and cause actual results to vary materially from expectations include, but are &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; limited to, risks from lack of available financing and insufficient capital, performance of PowerBuoys, its inability to market and commercialize its PowerBuoys, technology development, scalability of technology and production, dependence on skills of key personnel, concentration of customers and suppliers, deployment risks and laws, regulations and permitting In order to continue to implement its business strategy, the Company requires additional equity and/or debt financing. The Company closed &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;four&lt;/div&gt; equity financing arrangements during the year ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April 30, 2017 &lt;/div&gt;and subsequently on &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 2, 2017. &lt;/div&gt;&lt;/div&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;The Company does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; currently have any committed sources of debt or equity financing, and the Company cannot assure that additional equity and/or debt financing will be available to the Company as needed on acceptable terms, or at all. Historically, the Company has raised capital through securities sales in the public capital markets. If sufficient additional financing is &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; obtained when needed, the Company &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;be required to further curtail or limit operations, product development costs, and/or selling, general and administrative activities in order to reduce its cash expenditures. This could cause the Company to be unable to execute its business plan, take advantage of future opportunities and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;cause it to scale back, delay or eliminate some or all of its product development activities and/or reduce the scope of or cease its operations.&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;Historically, the Company has funded its operations principally through public and private sales of our equity. In &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; October 2015, &lt;/div&gt;the Company entered into an At the Market Offering Agreement (&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;&amp;#x201c;2015&lt;/div&gt; ATM Agreement&amp;#x201d;) with H.C.

Under this agreement, the cash is on deposit at Santander Bank and serves as security for letter of credit issued by Santander Bank for the lease of new warehouse/office space in Monroe Township, New Jersey. The agreement cannot be extended beyond &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; January 31, 2025, &lt;/div&gt;but is cancelable at the discretion of the bank.&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;&lt;div style=" MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;The &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;third&lt;/div&gt; agreement was between the Company and the New Jersey Board of Public Utilities (&amp;#x201c;NJBPU&amp;#x201d;). The Company received a &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$0.5&lt;/div&gt; million recoverable grant award from the NJBPU, repayable over a &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;five&lt;/div&gt;-year period beginning in &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; November 2011. &lt;/div&gt;The agreement also required the Company to annually assign to the NJBPU a certificate of deposit in an amount equal to the outstanding grant balance. As of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April 30, 2017, &lt;/div&gt;the grant was fully repaid and therefore there was &lt;div style="display: inline;

The Stipulation provides, among other things, for a settlement payment by or on behalf of the Company of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$3.0&lt;/div&gt; million in cash, of which the Company would pay &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$0.5&lt;/div&gt; million and the Company&amp;#x2019;s insurer would pay &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$2.5&lt;/div&gt; million, and the issuance by the Company of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;380,000&lt;/div&gt; shares (valued at &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$0.6&lt;/div&gt; million on the date the Stipulation was signed by the parties) of its Common Stock to the class members.

The Court approved the Stipulation on &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; August 3, 2016.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;On &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; October 25, 2016, &lt;/div&gt;the Court approved and entered a Stipulation and Order that, among other things, (i) consolidated the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;four&lt;/div&gt; derivative actions; (ii) identified plaintiff Pucillo as the lead plaintiff in the consolidated actions; and (iii) stayed the consolidated actions pending the settlement hearing scheduled for &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; November 14, 2016 &lt;/div&gt;in the securities class action and further order of the Court. Defendants have &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; responded to the consolidated derivative actions because the actions remain stayed pending further order from the Court.&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;The Company and certain of its current directors are defendants in a lawsuit filed by an alleged shareholder in the Superior Court of New Jersey, Mercer County Chancery Division on &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; January 25, 2016, &lt;/div&gt;captioned &lt;div style="display: inline; font-style: italic;"&gt;Stern v. Ocean Power Technologies, Inc., et al.,&lt;/div&gt; Civil Action &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;No.&lt;/div&gt; C-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;5&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;16.&lt;/div&gt; The complaint alleges that certain provisions of the Company&amp;#x2019;s&amp;nbsp;Certificate of Incorporation and By-laws providing that the Company&amp;#x2019;s directors &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;be removed only for cause and only by an affirmative vote of at least &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;75%&lt;/div&gt; of the votes which all the stockholders would be entitled to cast in any annual election of directors are invalid under Section &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;141&lt;/div&gt;(k) of the Delaware General Corporation Law. The Complaint asserts a breach of fiduciary claim against the director defendants and a declaratory judgment claim against all defendants seeking, among other things, to invalidate the challenged provisions and declare that the Company&amp;#x2019;s directors &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;be removed and replaced without cause and by a simple majority vote. The Complaint sought declaratory and injunctive relief as well as unspecified costs and attorneys&amp;#x2019; fees. By Unanimous Written Consent dated &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 17, 2016, &lt;/div&gt;the Company&amp;#x2019;s Board of Directors amended the Company&amp;#x2019;s By-laws to delete the &amp;#x201c;only for cause&amp;#x201d; requirement, thereby allowing for removal of directors with or without cause by the Company&amp;#x2019;s stockholders.&amp;nbsp; In addition, the Board proposed, subject to approval by the Company&amp;#x2019;s stockholders at the next annual general meeting of stockholders, a similar amendment to the director removal provision in the Company&amp;#x2019;s&amp;nbsp;Certificate of Incorporation.&amp;nbsp; On &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 30, 2016, &lt;/div&gt;the Court approved a Stipulation and Proposed Order Staying Proceedings that, among other things, stayed the case pending the stockholder vote on the proposed amendment to the Company&amp;#x2019;s&amp;nbsp;Certificate of Incorporation; On &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; September 2, 2016, &lt;/div&gt;the Company filed a definitive proxy statement with the SEC which included the proposed amendment of the director removal rovision in the Company&amp;#x2019;s Certificate of Incorporation. At the annual shareholder meeting on &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; October 21, 2016, &lt;/div&gt;the proposal was &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; approved because an insufficient number of votes were cast to satisfy the requirement that the proposal be approved by the holders of at least &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;75%&lt;/div&gt; of the outstanding shares of common stock entitled to vote at the meeting.&amp;nbsp; However, stockholders approved an amendment to the Company&amp;#x2019;s Certificate of Incorporation to add a provision which requires that any provision of the Certificate of Incorporation that is contrary to a requirement of the Delaware General Corporate Law shall be read in conformity with the applicable requirement of the Delaware General Corporate Law&lt;/div&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;. On &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April 12, 2017, &lt;/div&gt;the parties in the &lt;div style="display: inline; font-style: italic;"&gt;Stern&lt;/div&gt; lawsuit executed a settlement that required the Company to file a Form &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;8&lt;/div&gt;-K (which was filed on &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April 17, 2017) &lt;/div&gt;with the U.S. Securities and Exchange Commission announcing that the Company will follow its By-Laws as opposed to its Certificate of Incorporation as regards the director removal provisions; and (&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2&lt;/div&gt;) to pay the &lt;div style="display: inline; font-style: italic;"&gt;Stern&lt;/div&gt; plaintiff an amount equal to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$22,500&lt;/div&gt; to compensate the plaintiff for the legal costs of bringing the lawsuit. Also on &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April 17, 2017, &lt;/div&gt;the parties executed a Stipulation of Dismissal that was subsequently filed with the court. The Company paid the plaintiff&amp;#x2019;s counsel the amount required by the settlement agreement within the time period required by the settlement agreement. &lt;/div&gt;&lt;/div&gt; &lt;div style=" MARGIN-BOTTOM: 0pt; MARGIN-TOP: 0pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;    &lt;div style=" MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;On &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 26, 2017, &lt;/div&gt;an attorney claiming to represent &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;two&lt;/div&gt; stockholders sent the Company&amp;#x2019;s Board of Directors a Stockholder Litigation Demand letter (&amp;#x201c;Stockholder Demand&amp;#x201d;). The Stockholder Demand alleges that the voting of shares for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;1&lt;/div&gt;-for-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;10&lt;/div&gt; reverse stock split at the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2015&lt;/div&gt; annual meeting of stockholders held on &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; October 22, 2015 &lt;/div&gt;was &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; properly counted, and further alleges that, although the Company reported the reverse stock split as having been passed, if the vote was properly counted the reverse stock split would &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; have been approved. The Stockholder Demand requests the Board of Directors either to deem the reverse stock split as ineffective and disclose the same or to seek a proper and effective stockholder ratification of the reverse stock split. In addition, the Stockholder Demand requests the Board of Directors to adopt and implement adequate internal controls and systems to prevent the alleged improper voting from recurring. On &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 23, 2017, &lt;/div&gt;the Company responded to the Stockholder Demand, explained the procedures that were followed for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2015&lt;/div&gt; annual meeting of stockholders and provided the Oath of the Inspector of Elections and the Certificate of the Inspector of Elections that certified as accurate the results of the voting at the meeting including voting on the reverse stock split proposal. On &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 26, 2017, &lt;/div&gt;the attorney representing the alleged stockholders replied to the Company&amp;#x2019;s response, further alleged that the proxy statement underlying the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2015&lt;/div&gt; annual meeting provided voting instructions that misled the stockholders regarding whether their brokers could vote on the reverse stock split proposal, and renewed their requests of the Board.&lt;/div&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt; &lt;/div&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;The Company is evaluating further the Stockholder Demand and the reply letter and will respond in due course. &lt;div style="display: inline; font-weight: bold;"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" MARGIN-BOTTOM: 0pt; MARGIN-TOP: 0pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: left; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;Employment Litigation&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;On &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 10, 2014, &lt;/div&gt;the Company announced that it had terminated Charles Dunleavy as its Chief Executive Officer and as an employee of the Company for cause, effective &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 9, 2014, &lt;/div&gt;and that Mr. Dunleavy had also been removed from his position as Chairman of the Board of Directors. On &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 17, 2014, &lt;/div&gt;Mr. Dunleavy wrote to the Company stating that he had retained counsel to represent him in connection with an alleged wrongful termination of his employment. On &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; July 28, 2014, &lt;/div&gt;Mr. Dunleavy resigned from the Board and the boards of directors of the Company's subsidiaries. The Company and Mr. Dunleavy have agreed to suspend his alleged employment claims pending resolution of the shareholder litigation, and have since agreed to continue to the suspension pending resolution of the derivatives litigation.&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 22.5pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;Except for the Stipulation agreement noted previously, we have &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; established any provision for losses relating to these claims and pending litigation. Due to the stages of these proceedings, and considering the inherent uncertainty of these claims and litigation, at this time we are &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; able to predict or reasonably estimate whether we have any possible loss exposure or the ultimate outcome of these claims. &lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: left; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;(b) Regulatory Matters&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;SEC Investigation&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;On &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; February 4, 2015, &lt;/div&gt;the Company received a subpoena from the SEC requesting information related to the VWP Project. The Company has provided information to the SEC in response to that subpoena. As part of the same investigation, on &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; July 12, 2016, &lt;/div&gt;the SEC issued &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;second&lt;/div&gt; subpoena requesting information related to the Company&amp;#x2019;s &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April 4, 2014 &lt;/div&gt;public offering. The Company has provided information to the SEC in response&amp;nbsp;to that subpoena. The SEC investigation is ongoing and the Company continues to cooperate with the SEC in its investigation. We are unable to predict what action, if any, might be taken by the SEC or its staff as a result of this investigation or what impact, if any, the cost of responding to the SEC&amp;#x2019;s investigation or its ultimate outcome might have on our financial position, results of operations or liquidity. We have &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; established any provision for losses relating to this matter.&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: left; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;Spain IVA (sales tax)&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: left; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;In &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; June 2012, &lt;/div&gt;the Company received notice that the Spanish tax authorities are inquiring into its &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2010&lt;/div&gt; IVA (value-added tax) filing for which the Company benefitted from the offset of approximately &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$0.3&lt;/div&gt; million of input tax. The Company believed that the tax credit was properly claimed and, therefore, &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;no&lt;/div&gt; liability was recorded. The Company issued &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;two&lt;/div&gt; letters of credit totaling &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;&amp;#x20ac;0.3&lt;/div&gt; million (&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$0.3&lt;/div&gt; million) at the request of the Spanish tax authorities. On &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; January 31, 2017 &lt;/div&gt;the Company received &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$0.2&lt;/div&gt; million from the Spanish tax authorities as a result of the conclusion of the inquiry. In addition, during &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; February 2017, &lt;/div&gt;the Spanish tax authorities approved of the release of the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;two&lt;/div&gt; outstanding letters of credit.&lt;/div&gt;&lt;/div&gt; &lt;div style=" MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;    &lt;div style=" MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;Spain Income Tax Audit&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: left; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;We are currently undergoing an income tax audit in Spain for the period from &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2008&lt;/div&gt; to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2014,&lt;/div&gt; when our Spanish branch was closed. The branch reported net operating losses for each of the years reported. It is anticipated that we will be assessed a penalty relating to these tax years for these losses.

On &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; October 21, 2016 &lt;/div&gt;upon approval by the Company&amp;#x2019;s stockholders the Company increased the number of shares authorized for issuance to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;640,703.&lt;/div&gt; If any award under the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2006&lt;/div&gt; Stock Incentive Plan or &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2015&lt;/div&gt; Plan expires, is cancelled, terminates unexercised or is forfeited, those shares become again available for grant under the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2015&lt;/div&gt; Plan.

The maximum number of shares of stock subject to Awards that can be granted under the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2015&lt;/div&gt; Plan in any &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt; calendar year to any person, other than a non-employee director, is &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;75,000.&lt;/div&gt; However, incentive stock options &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;only be granted to employees. The limitation on the amount of shares of stock issuable under the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2015&lt;/div&gt; Plan is subject to adjustment in the event of certain changes in the Company&amp;#x2019;s capital stock, such as recapitalizations, reclassifications, stock splits, reverse stock splits, spin-offs, combinations of our stock, exchanges of the Company&amp;#x2019;s stock and other increases or decreases in the Company&amp;#x2019;s stock without receipt of consideration. &lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 22.5pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;The &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2015&lt;/div&gt; Plan will terminate &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;ten&lt;/div&gt; years after its effective date, in &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; October 2025, &lt;/div&gt;but is subject to earlier termination as provided in the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2015&lt;/div&gt; Plan.&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 22.5pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;A dividend equivalent right is an award entitling the recipient to receive credits based on cash distributions that would have been paid to the recipient on the shares of Common Stock specified in the dividend equivalent right if such shares had been issued to and held by the recipient of the dividend equivalent right as of the record date. A dividend equivalent right &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;be granted to any grantee under the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2015&lt;/div&gt; Plan, but &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; be granted in connection with or related to an award of options or SARs under the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2015&lt;/div&gt; Plan. The terms and conditions of any dividend equivalent right shall be as set forth in the award agreement relating to such right. Unless the committee administering the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2015&lt;/div&gt; Plan otherwise provides in an award agreement, a grantee&amp;#x2019;s rights in all dividend equivalent rights will automatically terminate upon the grantee&amp;#x2019;s termination of service with the Company. &lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 22.5pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;Performance-based awards &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;be granted by the committee administering the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2015&lt;/div&gt; Plan in such amounts and upon such terms as the committee administering the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2015&lt;/div&gt; Plan determines. Generally, performance-based awards will have an actual or target number of shares of Common Stock or initial value that is set by the committee at the time of grant. The committee administering the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2015&lt;/div&gt; Plan has the discretion to set performance goals which, depending on the extent to which they are achieved, will determine the value and/or the number of shares of Common stock subject to a performance-based award that will be paid out to the grantee. The right of a grantee to exercise or receive a grant or settlement of any performance-based award, and the timing thereof, will be subject to the performance conditions specified by the committee, and will entitle the grantee to receive cash or shares of our Common Stock upon the attainment of the specified performance goals over a specified performance period. &lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 22.5pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;

During fiscal &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2017,&lt;/div&gt; the Company granted &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;223,662&lt;/div&gt; shares subject to service-based vesting requirements and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;no&lt;/div&gt; shares subject to performance-based vesting requirements. The achievement or vesting requirement of the performance-based grants is tied to the Company&amp;#x2019;s total shareholder return (TSR) relative to the total shareholder return of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; alternative energy Exchange Traded Funds as measured over a specific performance period. &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;No&lt;/div&gt; vesting of the relevant shares will occur in instances where the Company&amp;#x2019;s TSR for the relevant period is below &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;80%&lt;/div&gt; of the peer group. However, additional opportunities to vest some or all of a portion of the shares in a subsequent period &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;occur. Compensation expense for these awards with market-based vesting is calculated based on the estimated fair value as of the grant date utilizing a Monte Carlo simulation model and is recognized over the service period on a straight-line basis. &lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;In &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; January 2016, &lt;/div&gt;the Board of Directors authorized a modification to certain outstanding restricted stock grants, which converted certain grants with performance-based grants to service based grants. The modification of the restricted stock grants did &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; have a material impact on the Company&amp;#x2019;s statement of operations for the fiscal year ended &lt;div style="display: inline;

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). GAAP specifies a &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt;-level hierarchy that is used when measuring and disclosing fair value. The fair value hierarchy gives the highest priority to quoted prices available in active markets (i.e., observable inputs) and the lowest priority to data lacking transparency (i.e., unobservable inputs). An instrument&amp;#x2019;s categorization within the fair value hierarchy is based on the lowest level of significant input to its valuation. The following is a description of the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; hierarchy levels.&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: center; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;table style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif; WIDTH: 97.3%; MARGIN-RIGHT: 2.7%; TEXT-INDENT: 0px;" cellspacing="0" cellpadding="0" border="0"&gt;  &lt;tr&gt; &lt;td style="WIDTH: 10%; VERTICAL-ALIGN: top"&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;Level &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;1&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/td&gt; &lt;td style="WIDTH: 90%; VERTICAL-ALIGN: top"&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences and carry forwards become deductible or are utilized. As of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April&amp;nbsp;&lt;/div&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;30,&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2017&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2016,&lt;/div&gt; based upon the level of historical taxable losses, valuation allowances of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$54.7&lt;/div&gt; million and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$52.6&lt;/div&gt; million, respectively, were recorded to fully offset deferred tax assets. The valuation allowance increased &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$2.1&lt;/div&gt; million and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$1.8&lt;/div&gt; during the years ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April&amp;nbsp;&lt;/div&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;30,&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2017&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2016,&lt;/div&gt; respectively.&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: left; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;    &lt;div style=" MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;As of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April&amp;nbsp;&lt;/div&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;30,&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2017,&lt;/div&gt; the Company had net operating loss carry forwards for federal income tax purposes of approximately &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$130.5&lt;/div&gt; million, which begin to expire in fiscal &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2019.&lt;/div&gt; The Company also had federal research and development tax credit carry forwards of approximately &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$2.8&lt;/div&gt; million as of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April&amp;nbsp;&lt;/div&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;30,&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2017,&lt;/div&gt; which begins to expire in &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2019.&lt;/div&gt; The Tax Reform Act of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;1986&lt;/div&gt; contains provisions that limit the utilization of net operating loss and tax credit carry forwards if there has been an ownership change, as defined. The Company has determined that such an ownership change, as described in Section&amp;nbsp;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;382&lt;/div&gt; of the Internal Revenue Code, occurred in conjunction with the Company's U.S. initial public offering in &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April 2007. &lt;/div&gt;The Company's annual Section&amp;nbsp;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;382&lt;/div&gt; limitation is approximately &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$3.3&lt;/div&gt; million. The Section&amp;nbsp;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;382&lt;/div&gt; limitation is cumulative from year to year, and thus, to the extent net operating loss or other credit carry forwards are &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; utilized up to the amount of the available annual limitation, the limitation is carried forward and added to the following year's available limitation. Such limitation only applies to net operating losses incurred in periods prior to the ownership change. The Company has &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; performed additional analysis on ownership changes that &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;have occurred subsequently to further limit the ability to utilize net tax attributes. As of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April&amp;nbsp;&lt;/div&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;30,&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2017,&lt;/div&gt; the Company had state net operating loss carry forwards of approximately &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$21.6&lt;/div&gt; million which begin to expire in &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2019,&lt;/div&gt; which also &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;be limited to utilization limitations. As of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April&amp;nbsp;&lt;/div&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;30,&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2017,&lt;/div&gt; the Company had foreign net operating loss carry forwards of approximately &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$16.9&lt;/div&gt; million. The ability to utilize these carry forwards &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;also be limited in the event of a significant change to ownership.&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: left; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;During the years ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April 30, 2017 &lt;/div&gt;and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2016,&lt;/div&gt; the Company sold New Jersey State net operating losses in the amount of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$7.8&lt;/div&gt; million and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$19.7&lt;/div&gt; million, respectively, resulting in the recognition of income tax benefits of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$0.7&lt;/div&gt; million and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$1.7&lt;/div&gt; million, respectively, recorded in the Company&amp;#x2019;s Statement of Operations.&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;The Company applies the guidance issued by the FASB for the accounting and reporting of uncertain tax positions. The guidance requires the Company to recognize in its consolidated financial statements the impact of a tax position if that position is more likely than &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; to be sustained upon examination, based on the technical merits of the position. We are currently undergoing an income tax audit in Spain for the period from &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2008&lt;/div&gt; to &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2014,&lt;/div&gt; when our Spanish branch was closed. The branch reported net operating losses for each of the years reported. It is anticipated that we will be assessed a penalty relating to these tax years for these losses. We have estimated this penalty to be &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$132&lt;/div&gt; thousand, and as such, for the period ended &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April 30, 2017, &lt;/div&gt;we have recorded &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$132&lt;/div&gt; thousand for this penalty to Selling, general and administrative costs in the Statement of Operations. At &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April&amp;nbsp;&lt;/div&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;30,&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2017&lt;/div&gt; and &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2016,&lt;/div&gt; the Company had &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;no&lt;/div&gt; other unrecognized tax positions. The Company does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; expect any material increase or decrease in its income tax expense in the next &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;twelve&lt;/div&gt; months, related to examinations or uncertain tax positions. U.S. federal and state income tax returns were audited through fiscal &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2014&lt;/div&gt; and fiscal &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2010&lt;/div&gt; respectively. Net operating loss and credit carry forwards since inception remain open to examination by taxing authorities, and will continue to remain open for a period of time after utilization.&amp;nbsp;&amp;nbsp;&lt;/div&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;The Company does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; have any interest or penalties accrued related to uncertain tax positions as it does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; have any unrecognized tax benefits. &lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</us-gaap:IncomeTaxDisclosureTextBlock>

Recognized income tax positions are measured at the largest amount that is greater than &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;50%&lt;/div&gt; likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.

This new revenue recognition model provides a &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;five&lt;/div&gt;-step analysis in determining when and how revenue is recognized. The new model will require revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. The FASB subsequently issued additional clarifying standards to address issues arising from implementation of the new revenue standard, including a &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt;-year deferral of the effective date for the new revenue standard.

The standard provides accounting guidance that will be used along with existing auditing standards. The new standard applies to all entities for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;first&lt;/div&gt; annual period ending after &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December 15, 2016, &lt;/div&gt;and interim periods thereafter.

The update significantly revises an entity's accounting related to the classification and measurement of investments in equity securities and the presentation of certain fair value changes for financial liabilities measured at fair value. It also amends certain disclosure requirements associated with the fair value of financial instruments. The update will take effect for public companies for fiscal years beginning after &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December 15, 2017, &lt;/div&gt;including interim periods within those fiscal years.

Depreciation and amortization is calculated using the straight-line method over the estimated useful lives of the assets. Expenses for maintenance and repairs are charged to operations as incurred. Property and equipment is also reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of the asset exceeds its estimated future cash flows, then an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. &lt;/div&gt;&lt;/div&gt;

Under cost plus contracts, customers are billed for actual expenses incurred plus an agreed-upon fee. Under cost plus contracts, a profit or loss on a project is recognized depending on whether actual costs are more or less than the agreed upon amount. &lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;The Company has &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;two&lt;/div&gt; types of fixed price contracts, firm fixed price and cost-sharing. Under firm fixed price contracts, the Company receives an agreed-upon amount for providing products and services specified in the contract, a profit or loss is recognized depending on whether actual costs are more or less than the agreed upon amount. Under cost-sharing contracts, the fixed amount agreed upon with the customer is only intended to fund a portion of the costs on a specific project. Under cost sharing contracts, an amount corresponding to the revenue is recorded in cost of revenues, resulting in gross profit on these contracts of zero. The Company&amp;#x2019;s share of the costs is recorded as product development expense. &lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt 30pt 0pt 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 49.5pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;Generally, revenue under fixed price or cost plus contracts is recognized using the cost to cost percentage-of-completion method, measured by the ratio of costs incurred to total estimated costs at completion. In certain circumstances, revenue under contracts that have specified milestones or other performance criteria &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;be recognized only when the customer acknowledges that such criteria have been satisfied. If an arrangement involves multiple deliverables, the delivered items are considered separate units of accounting if the items have value on a stand-alone basis. Amounts allocated to each element are based on its objectively determined fair value, such as the sales price for the product or service when it is sold separately or competitor prices for similar products or services.&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;&lt;div style=" MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;In addition, recognition of revenue (and the related costs) &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;be deferred for fixed price contracts until contract completion if the Company is unable to reasonably estimate the total costs of the project prior to completion. These contracts are subject to interpretation and management &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;make a judgment as to the amount of revenue earned and recorded. Because the Company has a small number of contracts, revisions to the percentage-of-completion determination, management interpretation or delays in meeting performance and&lt;/div&gt; &lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;contractual criteria or in completing projects &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;have a significant effect on revenue for the periods involved. Upon anticipating a loss on a contract, the Company recognizes the full amount of the anticipated loss in the current period.&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;Unbilled receivables represent expenditures on contracts, plus applicable profit margin, &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; yet billed. Unbilled receivables are normally billed and collected within &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt; year. Billings made on contracts are recorded as a reduction of unbilled receivables, and to the extent that such billings and cash collections exceed costs incurred plus applicable profit margin, they are recorded as unearned revenues.&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;</us-gaap:RevenueRecognitionPolicyTextBlock>

Significant items subject to such estimates and assumptions include the recoverability of the carrying amount of property and equipment; fair value of warrant liabilities; valuation allowances for receivables and deferred income tax assets; estimated costs to complete projects and percentage of completion of customer contracts for purposes of revenue recognition. Actual results could differ from those estimates. The current economic environment, particularly the macroeconomic pressures in certain European countries, has increased the degree of uncertainty inherent in those estimates and assumptions.&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 21.6pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;table style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif; WIDTH: 100%; TEXT-INDENT: 0px;" cellspacing="0" cellpadding="0" border="0"&gt;  &lt;tr&gt; &lt;td style="WIDTH: 18pt; VERTICAL-ALIGN: top"&gt; &lt;div style=" TEXT-ALIGN: left; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;(c)&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/td&gt; &lt;td style="VERTICAL-ALIGN: top"&gt; &lt;div style=" TEXT-ALIGN: left; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;Revenue Recognition&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/td&gt; &lt;/tr&gt;  &lt;/table&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;The Company&amp;#x2019;s contracts are either cost plus or fixed price contracts. Under cost plus contracts, customers are billed for actual expenses incurred plus an agreed-upon fee. Under cost plus contracts, a profit or loss on a project is recognized depending on whether actual costs are more or less than the agreed upon amount. &lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;The Company has &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;two&lt;/div&gt; types of fixed price contracts, firm fixed price and cost-sharing. Under firm fixed price contracts, the Company receives an agreed-upon amount for providing products and services specified in the contract, a profit or loss is recognized depending on whether actual costs are more or less than the agreed upon amount. Under cost-sharing contracts, the fixed amount agreed upon with the customer is only intended to fund a portion of the costs on a specific project. Under cost sharing contracts, an amount corresponding to the revenue is recorded in cost of revenues, resulting in gross profit on these contracts of zero. The Company&amp;#x2019;s share of the costs is recorded as product development expense. &lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt 30pt 0pt 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 49.5pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;Generally, revenue under fixed price or cost plus contracts is recognized using the cost to cost percentage-of-completion method, measured by the ratio of costs incurred to total estimated costs at completion. In certain circumstances, revenue under contracts that have specified milestones or other performance criteria &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;be recognized only when the customer acknowledges that such criteria have been satisfied. If an arrangement involves multiple deliverables, the delivered items are considered separate units of accounting if the items have value on a stand-alone basis. Amounts allocated to each element are based on its objectively determined fair value, such as the sales price for the product or service when it is sold separately or competitor prices for similar products or services.&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;&lt;div style=" MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;In addition, recognition of revenue (and the related costs) &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;be deferred for fixed price contracts until contract completion if the Company is unable to reasonably estimate the total costs of the project prior to completion. These contracts are subject to interpretation and management &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;make a judgment as to the amount of revenue earned and recorded. Because the Company has a small number of contracts, revisions to the percentage-of-completion determination, management interpretation or delays in meeting performance and&lt;/div&gt; &lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;contractual criteria or in completing projects &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;have a significant effect on revenue for the periods involved. Upon anticipating a loss on a contract, the Company recognizes the full amount of the anticipated loss in the current period.&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;Unbilled receivables represent expenditures on contracts, plus applicable profit margin, &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; yet billed. Unbilled receivables are normally billed and collected within &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt; year. Billings made on contracts are recorded as a reduction of unbilled receivables, and to the extent that such billings and cash collections exceed costs incurred plus applicable profit margin, they are recorded as unearned revenues.&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 21.6pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: left; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt; &lt;table style="FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif; WIDTH: 100%; TEXT-INDENT: 0px;" cellspacing="0" cellpadding="0" border="0"&gt;  &lt;tr&gt; &lt;td style="WIDTH: 18pt; VERTICAL-ALIGN: top"&gt; &lt;div style=" TEXT-ALIGN: left; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;(d)&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/td&gt; &lt;td style="VERTICAL-ALIGN: top"&gt; &lt;div style=" TEXT-ALIGN: left; MARGIN: 0pt; LINE-HEIGHT: 1.25"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&lt;div style="display: inline; font-style: italic;"&gt;&lt;div style="display: inline; font-weight: bold;"&gt;Cash and Cash Equivalents&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/div&gt;&lt;/td&gt; &lt;/tr&gt;  &lt;/table&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;The Company considers all highly liquid investments with a maturity of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;three&lt;/div&gt; months or less when purchased to be cash equivalents.

The agreement contains provisions to ensure that the market value of the underlying assets remain sufficient to protect the Company in the event of default by the bank by requiring that the underlying securities have a total market value of at least &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;100%&lt;/div&gt; of the bank&amp;#x2019;s total obligations under the agreement.

The credit facility does &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; have an expiration date, but is cancelable at the discretion of the bank.

Under this agreement, the cash is on deposit at Santander Bank and serves as security for letter of credit issued by Santander Bank for the lease of new warehouse/office space in Monroe Township, New Jersey. The agreement cannot be extended beyond &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; January 31, 2025, &lt;/div&gt;but is cancelable at the discretion of the bank.&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;&lt;div style=" MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;The &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;third&lt;/div&gt; agreement was between the Company and the New Jersey Board of Public Utilities (&amp;#x201c;NJBPU&amp;#x201d;). The Company received a &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;$0.5&lt;/div&gt; million recoverable grant award from the NJBPU, repayable over a &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;five&lt;/div&gt;-year period beginning in &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; November 2011. &lt;/div&gt;The agreement also required the Company to annually assign to the NJBPU a certificate of deposit in an amount equal to the outstanding grant balance. As of &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; April 30, 2017, &lt;/div&gt;the grant was fully repaid and therefore there was &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;no&lt;/div&gt; certificate of deposit. &lt;/div&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;The following table summarizes restricted cash for the years ended &lt;div style="display: inline;

Depreciation and amortization is calculated using the straight-line method over the estimated useful lives of the assets. Expenses for maintenance and repairs are charged to operations as incurred. Property and equipment is also reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of the asset exceeds its estimated future cash flows, then an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. &lt;/div&gt;&lt;/div&gt;

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences and operating loss and tax credit carry forwards are expected to be recovered, settled or utilized. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; BACKGROUND-COLOR: #ffffff; TEXT-INDENT: 21.6pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt;&lt;div style=" MARGIN-BOTTOM: 0px; MARGIN-TOP: 0px"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman"&gt;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 36pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;The Company recognizes the effect of income tax positions only if those positions are more likely than &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; of being sustained upon examination. Recognized income tax positions are measured at the largest amount that is greater than &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;50%&lt;/div&gt; likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.

This new revenue recognition model provides a &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;five&lt;/div&gt;-step analysis in determining when and how revenue is recognized. The new model will require revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. The FASB subsequently issued additional clarifying standards to address issues arising from implementation of the new revenue standard, including a &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;one&lt;/div&gt;-year deferral of the effective date for the new revenue standard. Public companies should now apply the guidance in ASU &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2014&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;09&lt;/div&gt; to annual reporting periods beginning after &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December&amp;nbsp;&lt;/div&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;15,&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2017&lt;/div&gt; and interim periods within those annual periods. Earlier application is permitted only as of annual reporting periods beginning after &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December&amp;nbsp;&lt;/div&gt;&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;15,&lt;/div&gt; &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2016,&lt;/div&gt; including interim periods within that annual period. Companies &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;use either a full retrospective or a modified retrospective approach to adopt ASU &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2014&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;09.&lt;/div&gt; The Company has &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;not&lt;/div&gt; yet completed its final review of the impact of this guidance; however the Company anticipates applying the modified retrospective method upon adoption of ASU &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2014&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;09&lt;/div&gt; on &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; May 1, 2018.&lt;/div&gt;&lt;/div&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt; The impact to the Company could be affected by the nature and terms of potential future contracts with customers, as those contracts &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; may &lt;/div&gt;have terms that differ from the company&amp;#x2019;s current contracts. &lt;/div&gt;&lt;/div&gt; &lt;div style=" MARGIN-BOTTOM: 0pt; MARGIN-TOP: 0pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;&amp;nbsp;&lt;/div&gt;&lt;/div&gt; &lt;div style=" TEXT-ALIGN: justify; MARGIN: 0pt 0pt 0pt 7.5pt; LINE-HEIGHT: 1.25; TEXT-INDENT: 28.5pt"&gt;&lt;div style="display: inline; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman, Times, serif"&gt;In &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; August 2014, &lt;/div&gt;the FASB issued ASU &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;2014&lt;/div&gt;-&lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;15,&lt;/div&gt; &lt;div style="display: inline; font-style: italic;"&gt;&amp;#x201c;Disclosure of Uncertainties about an Entity&amp;#x2019;s Ability&lt;/div&gt; &lt;div style="display: inline; font-style: italic;"&gt;to Continue as a Going Concern&amp;#x201d;,&lt;/div&gt; which describes how an entity should assess its ability to meet obligations and sets rules for how this information should be disclosed in the financial statements. The standard provides accounting guidance that will be used along with existing auditing standards. The new standard applies to all entities for the &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt;first&lt;/div&gt; annual period ending after &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December 15, 2016, &lt;/div&gt;and interim periods thereafter. Early application is permitted.

The update significantly revises an entity's accounting related to the classification and measurement of investments in equity securities and the presentation of certain fair value changes for financial liabilities measured at fair value. It also amends certain disclosure requirements associated with the fair value of financial instruments. The update will take effect for public companies for fiscal years beginning after &lt;div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;"&gt; December 15, 2017, &lt;/div&gt;including interim periods within those fiscal years.
