Variable Interest Entity Maximum Loss Exposure
Variable Interest Entity Maximum Loss Exposure [Table Text Block]
Enterprise's maximum exposure to loss as a result of its involvement with the VIE, including how the maximum exposure is determined, the significant sources of the enterprise's exposure to the VIE, and the differences between the maximum exposure to loss and the liability recognized in its financial statements. It may also include factors such as the fair market value at which the registrant is carrying an asset and registrant guarantees. Also, whether the enterprise's maximum exposure to loss as a result of its involvement with the VIE cannot be quantified. In general, a VIE is a corporation, partnership, trust, or any other legal structure used for business purposes that either (a) does not have equity investors with voting rights or (b) has equity investors that do not provide sufficient financial resources for the entity to support its activities. A VIE often holds financial assets, including loans or receivables, real estate or other property. A VIE may be essentially passive or it may engage in research and development or other activities on behalf of another company.
