The Partnership’s maximum exposure under these arrangements is unknown. However, the Partnership has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.   The General Partner knows of no facts or circumstances that would make the Partnership’s contractual commitments outside standard mutual covenants applicable to commercial transactions between businesses. Accordingly, the Partnership believes that these indemnification obligations are made in the ordinary course of business as part of standard commercial and industry practice, and that any potential liability under the Partnership’s similar commitments is remote. Should any such indemnification obligation become payable, the Partnership would separately record and/or disclose such liability in accordance with GAAP. </div> </div>falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosure for each guarantee obligation, or each group of similar guarantee obligations, including (a) the nature of the guarantee, including its term, how it arose, and the events or circumstances that would require the guarantor to perform under the guarantee; (b) the maximum potential amount of future payments (undiscounted) the guarantor could be required to make under the guarantee; (c) the current carrying amount of the liability, if any, for the guarantor's obligations under the guarantee; and (d) the nature of any recourse provisions under the guarantee, and any assets held either as collateral or by third parties, and any relevant related party disclosure.
