The  Company also provides a family of best-in-class communications  processors.&amp;#160; For the network infrastructure market, the  Company provides integrated multi-core network processor  system-on-a-chip solutions for fixed, 3G and 4G mobile, VoIP and  multimedia applications. &amp;#160;TranSwitch&amp;#8217;s customers are  leading consumer electronics and telecom equipment companies around  the globe.&amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &lt;em&gt;&amp;#160;&lt;/em&gt;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-INDENT: 12.2pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &lt;em&gt;Liquidity&lt;/em&gt;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-INDENT: 12.2pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; TEXT-INDENT: 27.35pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  The Company has incurred significant operating losses and has used  cash in its operating activities for the past several years.  Operating losses have resulted from inadequate sales levels for the  cost structure. As of June 30, 2013, the Company has negative  working capital of approximately $&lt;font style=" FONT-SIZE: 10pt"&gt;7.7&lt;/font&gt; million. Included in negative working  capital, the Company has outstanding indebtedness to Bridge Bank  under its credit facility of $&lt;font style=" FONT-SIZE: 10pt"&gt;1.7&lt;/font&gt; million.&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; TEXT-INDENT: 27pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; TEXT-INDENT: 27pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  On April 3, 2013 the Company raised $&lt;font style=" FONT-SIZE: 10pt"&gt;3.6&lt;/font&gt; million&lt;font style="BACKGROUND-COLOR: transparent"&gt;, net of issuance costs of $&lt;font  style=" FONT-SIZE: 10pt"&gt;0.6&lt;/font&gt; million,&lt;/font&gt; in an  underwritten public offering. The offering consisted of the sale of  &lt;font style=" FONT-SIZE: 10pt"&gt;8,300,000&lt;/font&gt; units at a price to  the public of $&lt;font style=" FONT-SIZE: 10pt"&gt;0.50&lt;/font&gt; per unit.  Each unit consists of one share of common stock and a warrant to  purchase 0.50 of a share of common stock. The warrants have an  exercise price of $&lt;font style=" FONT-SIZE: 10pt"&gt;0.58&lt;/font&gt; per  share.&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; TEXT-INDENT: 27pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; TEXT-INDENT: 27pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  In 2012, the Company&amp;#160;effectuated&amp;#160;a restructuring which  primarily affected the telecom product unit and is expected to save  &lt;font style="BACKGROUND-COLOR: transparent"&gt;approximately&lt;/font&gt;  $&lt;font style=" FONT-SIZE: 10pt"&gt;8.0&lt;/font&gt; million in annual  operating costs. The Company began to see these cost savings during  the third quarter of 2012. With this restructuring, the Company has  cancelled all development programs related to its telecom product  lines and has redeployed all of its remaining research and  development resources to focus on its interoperable connectivity  solutions for consumer electronic and personal computer  markets.&amp;#160; The Company also announced its intentions to sell  its non-strategic assets. The Company is actively marketing its  telecom related patent portfolio to provide additional liquidity.  The Company continues to assess its cost structure in relationship  to its revenue levels, which may necessitate further expense  reductions. &lt;font style="BACKGROUND-COLOR: transparent"&gt;In June  2013 we continued to restructure the organization by significantly  reducing development activities and&amp;#160;effectuated another  restructuring which is expected to save an additional $&lt;font style=" FONT-SIZE: 10pt"&gt;2&lt;/font&gt; million per year and recorded a $&lt;font  style=" FONT-SIZE: 10pt"&gt;0.7&lt;/font&gt; restructuring charge. We  continue to assess our cost structure in relationship to our  revenue levels which may necessitate further expense  reductions.&lt;/font&gt;&amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; TEXT-INDENT: 27pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; TEXT-INDENT: 24.5pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  As with any operating plan, there are risks associated with the  Company&amp;#8217;s ability to execute it, including the current  economic environment in which the Company operates. Therefore,  there can be no assurance that the Company will be able to satisfy  its obligations, or achieve the operating improvements absent an  infusion of capital. If the Company is unable to execute &lt;font  style="BACKGROUND-COLOR: transparent"&gt;its operating&lt;/font&gt; plan, it  will need to find additional sources of cash not contemplated by  the current operating plan and/or raise additional capital to  sustain continuing operations as currently contemplated. There can  be no assurance that the additional funding sources will be  available to the Company upon favorable terms or at all.&amp;#160;Among  other things, if the Company cannot maintain compliance with its  covenant requirements on its bank financing facility or cannot  obtain appropriate waivers and modifications, the lenders may call  the debt. If the debt is called, the Company would need to obtain  new financing and there can be no assurance that it will be able to  do so. If the Company is unable to achieve its operating plan and  maintain compliance with its loan covenants and the debt is called,  the Company will not be able to continue as a going concern. The  accompanying condensed consolidated financial statements do not  include any adjustments relating to the recoverability and  classification of asset carrying amounts or the amounts and  classification of liabilities that may result from the outcome of  this uncertainty. These conditions raise substantial doubt about  the Company&amp;#8217;s ability to continue as a going concern.  Consequently, the audit report prepared by the Company&amp;#8217;s  independent registered public accounting firm relating to its  financial statements for the year ended December 31, 2012 includes  an explanatory paragraph expressing substantial doubt about the  Company&amp;#8217;s ability to continue as a going concern. If the  Company is unable to generate sufficient cash flows from operations  to meet its anticipated needs for working capital and capital  expenditures, it may need to raise additional funds. Such capital  may not be available on terms favorable or acceptable to the  Company, if at all. If the Company raises additional funds through  the issuance of equity securities, its stockholders may experience  dilution of their ownership interest, and the newly issued  securities may have rights superior to those of the Company&amp;#8217;s  common stock.&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; TEXT-INDENT: 24.5pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; TEXT-INDENT: 27pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  On December 4, 2012, &lt;font style=" "&gt;the Company received a letter  from Nasdaq (the &amp;#8220;Minimum Bid Price Notice&amp;#8221;) notifying  it that the closing bid price of its common stock was below the  $1.00 minimum bid price requirement for 30 consecutive business  days and, as a result, the Company no longer complied with the  minimum bid price requirement under Listing Rule 5550(a)(2) for  continued listing on Nasdaq. The Minimum Bid Price Notice also  stated that the Company has been provided an initial compliance  period of 180 calendar days, or until June 3, 2013, to regain  compliance with the minimum bid price requirement.&lt;/font&gt;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; TEXT-INDENT: 27pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; TEXT-INDENT: 27pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  On February 26, 2013, the Company received a letter from Nasdaq  (the &amp;#8220;Stockholders&amp;#8217; Equity Notice&amp;#8221;) notifying it  that the Company was no longer in compliance with the minimum  stockholders&amp;#8217; equity requirement of at least $&lt;font style=" FONT-SIZE: 10pt"&gt;2.5&lt;/font&gt; million for continued listing on  Nasdaq. The Stockholders&amp;#8217; Equity Notice did not result in the  immediate delisting of the Company&amp;#8217;s common stock from  Nasdaq. Rather, under the Nasdaq &lt;font style="BACKGROUND-COLOR: transparent"&gt;listing rules, the Company had 45  calendar days from the date of the Stockholder&amp;#8217;s Equity  Notice to submit to Nasdaq a plan to regain  compliance.&lt;/font&gt;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; TEXT-INDENT: 27pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-INDENT: 27pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  On June 6, 2013, the Company received a letter from the Listing  Qualifications Department of The Nasdaq Stock Market LLC ("Nasdaq")  advising it that, unless it appeals the determination by June 13,  2013, its securities would be scheduled for delisting from The  Nasdaq Capital Market (the "Capital Market") and would be suspended  at the opening of business on June 17, 2013 for failure to comply  with Listing Rules 5550(a)(2) and 5550(b)(1), as further described  above. The Company was also notified that Nasdaq will file a Form  25-NSE with the Securities and Exchange Commission ("SEC") to  remove the registrant's securities from listing and registration on  the Capital Market.&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-INDENT: 27pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-INDENT: 27pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  The Company has appealed the determination to a Hearings Panel (the  "Panel"), which will automatically stay the delisting of the  Company's securities and the filing of the Form 25-NSE pending the  issuance of a decision by the Panel. &lt;font style="BACKGROUND-COLOR: transparent"&gt;The Company made a  presentation&lt;/font&gt; to&amp;#160;the Panel &lt;font style="BACKGROUND-COLOR: transparent"&gt;on July 11, 2013 and is awaiting  its decision. There&lt;/font&gt; can be no assurance that the Panel will  grant the registrant's request for continued listing on the Capital  Market, or that, if granted, the Company's plan to regain  compliance and maintain the listing of its common stock on the  Capital Market will ultimately be successful.&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; TEXT-INDENT: 27pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; TEXT-INDENT: 27pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  If the Company is delisted and cannot obtain listing on another  major market or exchange, its stock&amp;#8217;s liquidity would suffer,  and it would likely experience reduced investor interest. Such  factors may result in a decrease in the Company&amp;#8217;s  stock&amp;#8217;s trading price. In addition, the failure to trade on a  national securities exchange may hinder the Company&amp;#8217;s efforts  to obtain financing.&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; TEXT-INDENT: 24.5pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; TEXT-INDENT: 24.5pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  As of June 30, 2013 and December 31, 2012, the Company had total  cash, cash equivalents and restricted cash balances of  approximately &lt;font style="COLOR: black"&gt;$&lt;font style=" FONT-SIZE: 10pt"&gt;0.8&lt;/font&gt;&lt;/font&gt; million and &lt;font style="COLOR: black"&gt;$&lt;font style=" FONT-SIZE: 10pt"&gt;2.2&lt;/font&gt;&lt;/font&gt;  million, respectively. These balances&amp;#160;and the Company&amp;#8217;s  credit facility are its primary sources of liquidity, as the  Company is not currently generating any significant positive cash  flow from our operations. &lt;font style="BACKGROUND-COLOR: transparent"&gt;The Company&amp;#8217;s availability on  this credit facility was $&lt;font style=" FONT-SIZE: 10pt"&gt;0.2&lt;/font&gt;  million on June 30, 2013.&lt;/font&gt;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; TEXT-INDENT: 24.5pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &amp;#160;&amp;#160;&amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;MARGIN: 0pt 0px 0pt 12.2pt; FONT: 10pt Times New Roman, Times, Serif"&gt;  &lt;em&gt;Concentrations of Credit Risk and Significant  Customers&lt;/em&gt;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-INDENT: 0.5in; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; TEXT-INDENT: 27pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  Financial instruments that potentially subject the Company to  significant concentrations of credit risk consist principally of  cash and cash equivalents and accounts receivable.&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; TEXT-INDENT: 0.5in; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; TEXT-INDENT: 24.5pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  Cash and cash equivalents are held by high-quality financial  institutions, thereby reducing credit risk concentrations. In  addition, the Company limits the amount of credit exposure to any  one financial institution.&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  &amp;#160;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; TEXT-INDENT: 24.5pt; MARGIN: 0pt 0px; FONT: 10pt Times New Roman, Times, Serif"&gt;  At June 30, 2013 and December 31, 2012, approximately &lt;font style=" FONT-SIZE: 10pt"&gt;65&lt;/font&gt;% and &lt;font style=" FONT-SIZE: 10pt"&gt;  71&lt;/font&gt;% of accounts receivable were due from five customers.
