Central had a loss from  operations for the year ended December 31, 2012 and the six months  ended June 30, 2013. During March 2013, the RZB Loan ($&lt;font style=" FONT-SIZE: 10pt"&gt;1,970,000&lt;/font&gt; at December 31, 2012) was  repaid with proceeds from the $&lt;font style=" FONT-SIZE: 10pt"&gt;2,500,000&lt;/font&gt; of total advances received by  Regional under the Hopewell Loan.&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt"&gt;&lt;font  size="2"&gt;&amp;#160;&lt;/font&gt;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; MARGIN: 0pt 0px 0pt 13.5pt; FONT: 10pt Times New Roman, Times, Serif"&gt;  Central&amp;#8217;s deficit in working capital, excluding the current  amounts due under the Hopewell Loan and income taxes, penalties and  interest, totaled $&lt;font style=" FONT-SIZE: 10pt"&gt;2,160,000&lt;/font&gt;  at June 30, 2013. Regional&amp;#8217;s unpaid income and sales taxes  totaled approximately $&lt;font style=" FONT-SIZE: 10pt"&gt;167,000&lt;/font&gt; at June 30, 2013, including  penalties and interest and excluding approximately $&lt;font style=" FONT-SIZE: 10pt"&gt;82,000&lt;/font&gt; of adjustments yet to be  recognized by the related tax authorities. In addition, the  Partnership is liable for tax penalties to the CAFTB of $&lt;font  style=" FONT-SIZE: 10pt"&gt;316,000&lt;/font&gt;. RVOP is also responsible  for contingencies associated with the TransMontaigne dispute (see  Note G &amp;#150; Commitments and Contingencies &amp;#150; TransMontaigne  Dispute). The Partnership and the General Partner have limited cash  resources and are dependent on Regional to fund ongoing corporate  expenses.&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt"&gt;&lt;font  size="2"&gt;&amp;#160;&lt;/font&gt;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; MARGIN: 0pt 0px 0pt 13.5pt; FONT: 10pt Times New Roman, Times, Serif"&gt;  Substantially all of Central&amp;#8217;s assets are pledged or  committed to be pledged as collateral for the Hopewell Loan, and  therefore, Central is unable to obtain additional financing  collateralized by those assets. Central believes that Regional will  have sufficient working capital for its ongoing operations assuming  (a) the Storage Tank is placed back into service as currently  projected, (b) the expected increase in revenues from recent  contracts entered into by Regional are realized, (c) the expiring  contracts during 2013 are renewed without disruption in service and  at terms no less favorable than the existing contract terms, (d)  that Regional&amp;#8217;s obligations to creditors are not accelerated,  (e) that Regional satisfactorily resolves the Litigation with SGR  and (f) that Regional&amp;#8217;s costs to operate do not increase.  Until such time as the aforementioned conditions are achieved,  Regional&amp;#8217;s working capital may not be adequate to meet  current cash requirements and Regional is unable to fund any amount  of working capital to Central. Regional is currently seeking to  obtain additional funding through an increase in the amounts  advanced under the Hopewell Loan or from a funding transaction  completed by the Partnership and/or the General Partner.&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt"&gt;&lt;font  size="2"&gt;&amp;#160;&lt;/font&gt;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; MARGIN: 0pt 0px 0pt 13.5pt; FONT: 10pt Times New Roman, Times, Serif"&gt;  Central&amp;#8217;s ability to raise capital is hindered by the  existing pledge and therefore the ability to obtain additional  capital over the cash generated from operations to make the  Hopewell Note payments, for payment of taxes, penalties and  interest, for payment of the contingent liabilities, for expansion,  repair of the Storage Tank, capital improvements to existing  assets, for working capital or otherwise is limited. In addition,  the Partnership has obligations under existing registrations rights  agreements. These rights may be a deterrent to any future equity  financings. Management continues to seek acquisition opportunities  for the Partnership to expand its assets and generate additional  cash from operations. As described above, there is no assurance  that Regional will have sufficient working capital to cover its  ongoing cash requirements or any of the ongoing overhead expenses  of the Partnership for the period of time that management believes  is necessary to complete an acquisition that will provide  additional working capital for the Partnership. If the Partnership  does not have sufficient cash reserves, its ability to pursue  additional acquisition transactions will be adversely impacted.  Furthermore, despite significant effort, the Partnership has thus  far been unsuccessful in completing an acquisition transaction.  There can be no assurance that the Partnership will be able to  complete an accretive acquisition or otherwise find additional  sources of working capital. If an acquisition transaction cannot be  completed or if additional funds cannot be raised and cash flow is  inadequate, the Partnership and/or Regional would be required to  seek other alternatives which could include the sale of assets,  closure of operations and/or protection under the U.S. bankruptcy  laws.&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt"&gt;&lt;font  size="2"&gt;&amp;#160;&lt;/font&gt;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; MARGIN: 0pt 0px 0pt 13.5pt; FONT: 10pt Times New Roman, Times, Serif"&gt;  In view of the matters described in the preceding paragraphs,  recoverability of the recorded asset amounts shown in the  accompanying consolidated balance sheet is dependent upon the  ability of (1) Regional to achieve operating results as currently  projected, (2) Regional to pay its creditors as required, including  the Hopewell Loan and the IRS and the VDOT amounts under  arrangements satisfactory to Regional (3) the Partnership resolving  favorably the exposure for late tax filing penalties to the CAFTB,  (4) satisfactory resolution to the Litigation with SGR, (5) RVOP  satisfactorily resolving the TransMontaigne dispute, (6) Regional  satisfactorily completing the repairs associated with the Storage  Tank, (7) the Partnership continuing to receive waiver of salaries  and expenses by the Partnership&amp;#8217;s executive officers until  sufficient working capital is received, (8) Regional&amp;#8217;s  ability to obtain additional advances under the Hopewell Loan and  (9) the Partnership&amp;#8217;s ability to receive additional  distributions from Regional or future advances from the General  Partner in amounts necessary to fund overhead until an acquisition  transaction is completed by the Partnership.&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt"&gt;&lt;font  size="2"&gt;&amp;#160;&lt;/font&gt;&lt;/div&gt;    &lt;div style="clear:both; FONT-FAMILY:Times New Roman;FONT-SIZE: 10pt;TEXT-ALIGN: justify; MARGIN: 0pt 0px 0pt 13.5pt; FONT: 10pt Times New Roman, Times, Serif"&gt;  The unaudited consolidated financial statements do not include any  adjustments related to the recoverability and classification of  recorded asset amounts or amounts and classification of liabilities  that might be necessary should Central be unable to obtain adequate  funding to maintain operations and to continue in existence.&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>Going Concern Disclosure [Text Block]</ElementDefenition><ElementReferences>No definition available.</ElementReferences><IsTotalLabel>false</IsTotalLabel><UnitID>0</UnitID><Label>REALIZATION OF ASSETS</Label></Row></Rows><Footnotes /><IsEquityReport>false</IsEquityReport><ReportName>REALIZATION OF ASSETS</ReportName><MonetaryRoundingLevel>UnKnown</MonetaryRoundingLevel><SharesRoundingLevel>UnKnown</SharesRoundingLevel><PerShareRoundingLevel>UnKnown</PerShareRoundingLevel><ExchangeRateRoundingLevel>UnKnown</ExchangeRateRoundingLevel><HasCustomUnits>true</HasCustomUnits><IsEmbedReport>false</IsEmbedReport><IsMultiCurrency>false</IsMultiCurrency><ReportType>Sheet</ReportType><RoleURI>http://www.pennoctane.com/role/RealizationOfAssets</RoleURI><NumberOfCols>1</NumberOfCols><NumberOfRows>2</NumberOfRows></InstanceReport>
