In  the opinion of management, all adjustments (which include normal  recurring and nonrecurring items) necessary to present fairly the  financial position, results of operations and cash flows in  conformity with generally accepted accounting principles for the  periods presented have been made. Interim operating results are not  necessarily indicative of operating results for a full year.&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt"&gt;  &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;  The preparation of our unaudited consolidated financial statements  requires management to make estimates and assumptions that affect  the reported amounts of assets and liabilities and the disclosure  of contingent assets and liabilities at the date of the unaudited  consolidated financial statements and the reported amounts of  revenues and expenses during the reporting periods. Certain  information and note disclosures normally included in the Company's  annual financial statements prepared in accordance with generally  accepted accounting principles have been condensed or omitted.  These consolidated financial statements should be read in  conjunction with the financial statements and notes thereto  included in the Company's September 30, 2012 Annual Report on Form  10-K previously filed by the Company with the Securities and  Exchange Commission, as amended on February 14, 2013.&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt"&gt;  &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;  The accompanying consolidated financial statements have been  prepared in conformity with accounting principles generally  accepted in the United States of America, which contemplates  continuation of the Company as a going concern. However, the  Company has failed to comply with the financial covenants set forth  in the terms of its outstanding loan agreements and sustained a  substantial loss from operations for the year ended September 30,  2012. The Company has continued to sustain losses from operations  for the nine months ended June 30, 2013. These factors raise  substantial doubt over the Company&amp;#8217;s ability to continue as a  going concern.&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt"&gt;  &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;  The Company continues to be in default of the financial covenants  set forth in the terms of its loan agreements for its fiscal third  quarter ended June 30, 2013. These covenants require the Company to  maintain specified ratios of earnings before interest, taxes,  depreciation and amortization (EBITDA) to fixed charges and to  total debt and senior debt. A default gives the lenders the right  to accelerate the maturity of the outstanding indebtedness.  Furthermore, Sovereign Bank, N.A, the Company&amp;#8217;s senior  lender, may, at its option, impose a default interest rate with  respect to the senior debt outstanding, which is 5% higher than the  rate otherwise in effect. To date, the lender has not taken any  such action. However, the Company cannot predict when or whether a  resolution of this situation will be achieved or if the higher  interest rate will be imposed.&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt"&gt;  &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;  The Company has accrued but not remitted interest payments to its  subordinated lender since February 2013. The Company is current  with all principal and interest payments due to its senior lender  through August 12, 2013, the date of this filing. Management  provided a revised forecast to its lenders in February 2013 and is  currently evaluating potential transactions involving the sales of  divisions and/or product lines which, if consummated, would result  in additional debt principal payments to the bank. Because of the  continuing default of the financial covenants and the possibility  of an acceleration of the indebtedness by the lenders, the Company  has classified all of its outstanding indebtedness as a current  liability in the accompanying consolidated balance sheets.&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt"&gt;  &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;  The Company&amp;#8217;s ability to continue as a going concern is  dependent upon its ability to generate future profitable operations  and positive cash flows and/or to obtain the necessary financing  from shareholders or other sources (including sales of divisions  and/or product lines) to meet its outstanding obligations and repay  its liabilities arising from normal business operations when they  become due.&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt"&gt;  &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;  In view of the matters described in the preceding paragraphs,  recoverability of a major portion of the recorded asset amounts  shown in the accompanying consolidated balance sheet is dependent  upon the continued operations of the Company. The consolidated  financial statements do not include any adjustments relating to the  recoverability and classification of recorded asset amounts or  amounts and classification of liabilities that might be necessary  should the Company be unable to continue in existence.&amp;#160;&lt;/div&gt;    &amp;#160;     &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;  The Company has taken and will continue to take actions to improve  its liquidity, including the implementation of a number of  initiatives designed to conserve cash, optimize profitability and  right-size the cost structure of its various businesses. The  Company has retained financial advisors to assist in evaluating  strategic and restructuring alternatives, including the potential  sale of product lines and/or a Company division. While the Company  is actively considering such strategic alternatives, there can be  no assurances that any such transaction will occur, or, if a  transaction is completed, it will be on terms favorable to the  Company. The Company does not currently have cash available to  satisfy its obligations under its indebtedness if it were to be  accelerated or payment demanded. If the Company is not able to  resolve its current defaults under its outstanding indebtedness and  improve its liquidity through the actions described above, it may  not have sufficient liquidity to meet its anticipated cash needs  for the next twelve months.&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt"&gt;  &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;  We consider events or transactions that have occurred after the  unaudited consolidated balance sheet date of June 30, 2013, but  prior to the filing of the unaudited consolidated financial  statements with the SEC on this Form 10-Q, to provide additional  evidence relative to certain estimates or to identify matters that  require additional disclosure, as applicable. Subsequent events  have been evaluated through the date of the filing of this  Quarterly Report on Form 10-Q with the SEC.&lt;/div&gt;  &lt;/div&gt;        </NonNumbericText><FootnoteIndexer /><CurrencyCode /><CurrencySymbol /><IsIndependantCurrency>false</IsIndependantCurrency><ShowCurrencySymbol>false</ShowCurrencySymbol><DisplayDateInUSFormat>false</DisplayDateInUSFormat></Cell></Cells><ElementDataType>nonnum:textBlockItemType</ElementDataType><SimpleDataType>na</SimpleDataType><ElementDefenition>The entire disclosure for the nature of an entity's business, the major products or services it sells or provides and its principal markets, including the locations of those markets.
