Such expenses are allocated among other entities affiliated with the General Partners based on estimates of the amount of time dedicated to each fund by individual administrative personnel. In the opinion of the General Partners, this allocation is a reasonable estimation of such expenses.

In addition, Wells Capital and Wells Management pay for certain operating expenses of the Partnership ("bill-backs") directly and invoice the Partnership for the reimbursement thereof on a quarterly basis. As presented in the accompanying balance sheets, due to affiliates as of &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;June&amp;#160;30, 2013&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; and &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;December&amp;#160;31, 2012&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; represents administrative reimbursements and bill-backs due to Wells Capital and/or Wells Management.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:12px;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;font-weight:bold;"&gt;Operational Dependency &lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:12px;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;The Partnership has engaged Wells Capital and Wells Management to provide certain essential services, including supervision of the management and leasing of its properties, asset acquisition and disposition services, as well as other administrative responsibilities, including accounting services and investor communications and relations. These agreements are terminable by either party upon &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;60&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt; days' written notice. As a result of these relationships, the Partnership's operations are dependent upon Wells Capital and Wells Management.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:12px;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;Wells Capital and Wells Management are owned and controlled by WREF. The operations of Wells Capital, Wells Investment Securities, Inc., Wells Management, Wells Core Office Income REIT Advisory Services, LLC, and their affiliates represent substantially all of the business of WREF. Accordingly, we focus on the financial condition of WREF when assessing the financial condition of Wells Capital and Wells Management. In the event that WREF were to become unable to meet its obligations as they become due, we might be required to find alternative service providers.&lt;/font&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:12px;text-align:justify;font-size:10pt;"&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;Future net income generated by WREF will be largely dependent upon the amount of fees earned by Wells Capital and Wells Management based on, among other things, the management of assets for WREF-sponsored programs and the volume of future acquisitions and dispositions of real estate assets by WREF-sponsored programs, as well as distribution income earned from its holdings of common stock of Piedmont REIT, which was acquired in connection with the Piedmont REIT internalization transaction. As of &lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;color:#000000;text-decoration:none;"&gt;June&amp;#160;30, 2013&lt;/font&gt;&lt;font style="font-family:inherit;font-size:10pt;"&gt;, the Partnership has no reason to believe that WREF does not have access to adequate liquidity and capital resources, including cash flow generated from operations, cash on hand, other investments, and borrowing capacity, necessary to meet its current and future obligations as they become due. Modifying service agreements between WREF, or its affiliates, and the Partnership, or other WREF-sponsored programs, could impact WREF's future net income and future access to liquidity and capital resources. For example, a large portion of WREF's income is derived under agreements with Columbia Property Trust, Inc. ("Columbia"), formerly known as Wells Real Estate Investment Trust II, Inc. Effective February 28, 2013, Columbia transitioned to self-management and indicated that it does not expect to rely on WREF for the same level of services beyond December 31, 2013. As such, WREF does not expect to receive significant compensation from Columbia beyond December 31, 2013.&lt;/font&gt;&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 related party transactions.
