Financing Arrangement [Abstract]
Financing Arrangement	Financing Arrangement In connection with tax increment financing for a parking garage we constructed in 1999, we are obligated to pay fixed special assessments over a 20-year period ending in 2019. The net present value of these assessments, discounted at the 6.93% interest rate on the underlying tax increment financing, is recorded as a financing obligation and is classified in liabilities held for sale on our Consolidated Balance Sheets. We receive special tax revenues and property tax rebates recorded in interest and other income, which are intended, but not guaranteed, to provide funds to pay the special assessments. We acquired the related tax increment financing bond in a privately negotiated transaction in 2007. Under the definitive agreements, dated as of December 21, 2015, relating to the sale of substantially all of our wholly-owned Country Club Plaza assets in Kansas City, MO (which we refer to as the "Plaza assets"), this tax increment financing bond will be assigned to the buyer of the Plaza assets as of the closing date at the agreed upon value of the principal amount and accrued interest, if any, then outstanding. Such value is included as part of the $660.0 million purchase price for the Plaza assets. This tax increment financing bond is classified in liabilities held for sale on our Consolidated Balance Sheets and was $7.4 million and $9.0 million at December 31, 2015 and 2014, respectively.

In connection with tax increment financing for a parking garage we constructed in 1999, we are obligated to pay fixed special assessments over a 20-year period ending in 2019. The net present value of these assessments, discounted at the 6.93% interest rate on the underlying tax increment financing, is recorded as a financing obligation and is classified in liabilities held for sale on our Consolidated Balance Sheets. We receive special tax revenues and property tax rebates recorded in interest and other income, which are intended, but not guaranteed, to provide funds to pay the special assessments. We acquired the related tax increment financing bond in a privately negotiated transaction in 2007. Under the definitive agreements, dated as of December 21, 2015, relating to the sale of substantially all of our wholly-owned Country Club Plaza assets in Kansas City, MO (which we refer to as the "Plaza assets"), this tax increment financing bond will be assigned to the buyer of the Plaza assets as of the closing date at the agreed upon value of the principal amount and accrued interest, if any, then outstanding. Such value is included as part of the $660.0 million purchase price for the Plaza assets.
