Debt Disclosure [Abstract]
Debt	Note 6 – Debt Mortgage Loans Payable On July 7, 2015, pursuant to the Transaction, the Company entered into a mortgage loan agreement (the “Mortgage Loan Agreement”) and mezzanine loan agreement (collectively, the “Loan Agreements”), providing for term loans in an initial principal amount of approximately $1,161 million (collectively, the “Mortgage Loans”) and a $100 million future funding facility (the “Future Funding Facility”). Pursuant to the terms of the Loan Agreements, amounts available under the Future Funding Facility were fully drawn by the Company on June 30, 2017. Such amounts were deposited into a redevelopment reserve and will be used to fund redevelopment activity at the Company’s properties. During the three months ended March 31, 2018, the Company reduced mortgage loans payable by $73.0 million as a result of the sale of a 50% joint venture interest in The Mark 302 and the disposition of four other assets. As of March 31, 2018, the aggregate principal amount outstanding under the Mortgage Loans and the Future Funding Facility was $1,137 million. Interest under the Mortgage Loans is due and payable on the payment dates, and all outstanding principal amounts are due when the loan matures on the payment date in July 2019, pursuant to the Loan Agreements. The Company has two one-year extension options subject to the payment of an extension fee and satisfaction of certain other conditions. Borrowings under the Mortgage Loans bear interest at the London Interbank Offered Rates (“LIBOR”) plus, as of March 31, 2018, a weighted-average spread of 478 basis points; payments are made monthly on an interest-only basis. The weighted-average interest rates for the Mortgage Loans and Future Funding Facility for the three months ended March 31, 2018 and March 31, 2017 were 6.40% and 5.54%, respectively. The Mortgage Loans and Future Funding Facility are secured by all of the Company’s Wholly Owned Properties and a pledge of its equity in the JVs. The Loan Agreements contain customary covenants for a real estate financing, including restrictions that limit the Company’s ability to grant liens on its assets, incur additional indebtedness, or transfer or sell assets, as well as those that may require the Company to obtain lender approval for certain major tenant leases or significant redevelopment projects. Such restrictions also include cash flow sweep provisions based upon certain measures of the Company’s and Sears Holdings’ financial and operating performance, including (a) where the “Debt Yield” (the ratio of net operating income for the mortgage borrowers to their debt) is less than 11.0%, (b) if the performance of Sears Holdings at the stores subject to the Master Lease with Sears Holdings fails to meet specified rent ratio thresholds, (c) if the Company fails to meet specified tenant diversification tests and (d) upon the occurrence of a bankruptcy or insolvency action with respect to Sears Holdings or if there is a payment default under the Master Lease with Sears Holdings, in each case, subject to cure rights, including providing specified amounts of cash collateral or satisfying tenant diversification thresholds. In November 2016, the Company and the servicer for its Mortgage Loans entered into amendments to the Loan Agreements to resolve a disagreement regarding one of the cash flow sweep provisions in the Loan Agreements. The principal terms of these amendments are that the Company (i) posted $30.0 million, and will post $3.3 million on a monthly basis, to a redevelopment project reserve account, which amounts may be used by the Company to fund redevelopment activity and (ii) extended the spread maintenance provision for prepayment of the loan by two months through March 9, 2018 (with the spread maintenance premium for the second month at a reduced amount). As a result of this agreement and the resolution of the related disagreement, no cash flow sweep was imposed. All obligations under the Loan Agreements are non-recourse to the borrowers and the pledgors of the JV Interests and the guarantors thereunder, except that (i) the borrowers and the guarantors will be liable, on a joint and several basis, for losses incurred by the lenders in respect of certain matters customary for commercial real estate loans, including misappropriation of funds and certain environmental liabilities and (ii) the indebtedness under the Loan Agreements will be fully recourse to the borrowers and guarantors upon the occurrence of certain events customary for commercial real estate loans, including without limitation prohibited transfers, prohibited voluntary liens, and bankruptcy. Additionally the guarantors delivered a limited completion guaranty with respect to future redevelopments undertaken by the borrowers at the properties, and the Company must maintain (i) a net worth of not less than $1.0 billion and (ii) a minimum liquidity of not less than $50.0 million, throughout the term of the Loan Agreements. The Company believes it is currently in compliance with all material terms and conditions of the Loan Agreements. The Company incurred $22.3 million of debt issuance costs related to the Mortgage Loans and Future Funding Facility which are recorded as a direct deduction from the carrying amount of the Mortgage Loans and Future Funding Facility and amortized over the term of the Loan Agreements. As of March 31, 2018, the unamortized balance of the Company’s debt issuance costs was $6.7 million as compared to $8.5 million as December 31, 2017. Unsecured Term Loan On February 23, 2017, the Operating Partnership, as borrower, and the Company, as guarantor, entered into a $200 million senior unsecured delayed draw term loan facility (the “Unsecured Delayed Draw Term Loan”) with JPP, LLC and JPP II, LLC as lenders (collectively, the “Original Lenders”) and JPP, LLC as administrative agent. The total commitment of the Lenders under the Unsecured Delayed Draw Term Loan was $200 million and the maturity date was December 31, 2017. The principal amount of loans outstanding under the Unsecured Delayed Draw Term Loan bore a base annual interest rate of 6.50%. If a cash flow sweep period were to have occurred and been continuing under the Company’s Mortgage Loan Agreement (i) the interest rate on any outstanding advances would have increased from and after such date by 1.5% per annum above the base interest rate and (ii) the interest rate on any advances made after such date would have increased by 3.5% per annum above the base interest rate. Accrued and unpaid interest was payable in cash, except that during the continuance of a cash flow sweep period under the Company’s Mortgage Loan Agreement, the Operating Partnership could elect to defer the payment of interest which deferred amount would be added to the outstanding principal balance of the loans. On February 23, 2017, the Operating Partnership paid to the Original Lenders an upfront commitment fee equal to $1.0 million. On May 24, 2017, the Operating Partnership paid to the Original Lenders an additional, and final, commitment fee of $1.0 million. The Unsecured Delayed Draw Term Loan required that the Company at all times maintain (i) a net worth of not less than $1.0 billion, and (ii) a leverage ratio not to exceed 60.0%. The Unsecured Delayed Draw Term Loan included customary representations and warranties, covenants and indemnities. The Unsecured Delayed Draw Term Loan also had customary events of default, including (subject to certain materiality thresholds and grace periods) payment default, failure to comply with covenants, material inaccuracy of representation or warranty, and bankruptcy or insolvency proceedings. If there was an event of default, the Lenders could declare all or any portion of the outstanding indebtedness to be immediately due and payable, exercise any rights they might have under any of the Unsecured Delayed Draw Term Loan documents, and require the Operating Partnership to pay a default interest rate on overdue amounts equal to 1.50% in excess of the applicable base interest rate. Mr. Edward S. Lampert, the Company’s Chairman, is the Chairman and Chief Executive Officer of ESL, which controls JPP, LLC and JPP II, LLC. The terms of the Unsecured Delayed Draw Term Loan were approved by the Company’s Audit Committee and the Company’s Board of Trustees (with Mr. Edward S. Lampert recusing himself). On December 27, 2017, the Operating Partnership, as borrower, and the Company, as guarantor, refinanced the Unsecured Delayed Draw Term Loan with a new $200 million unsecured term loan facility (the “Unsecured Term Loan”). The principal amount outstanding under the Unsecured Delayed Draw Term Loan at termination was $85 million. No prepayment penalties were triggered and the Unsecured Delayed Draw Term Loan terminated in accordance with its terms. The lenders under the Unsecured Delayed Draw Term Loan, JPP, LLC and JPP II, LLC, maintained their funding of $85 million in the Unsecured Term Loan, with JPP, LLC appointed as administrative agent under the Unsecured Term Loan. An affiliate of Empyrean Capital Partners, L.P., a Delaware limited partnership (and together with JPP, LLC and JPP II LLC, each an “Initial Lender” and collectively, the “Initial Lenders”), funded $60 million under the Unsecured Term Loan, resulting in a total of $145 million committed and funded under the Unsecured Term Loan at closing. Under an accordion feature, the Company has the right to increase the total commitments up to $200 million and place an additional $55 million of incremental loans with the Initial Lenders or new lenders. The Initial Lenders under the Unsecured Term Loan are not obligated to make all or any portion of the incremental loans. The Company used the proceeds of the Unsecured Term Loan, among other things, to refinance the Unsecured Delayed Draw Term Loan, to fund redevelopment projects and for other general corporate purposes. Loans under the Unsecured Term Loan are guaranteed by the Company. The Unsecured Term Loan matures on the earlier of (i) December 31, 2018 and (ii) the date on which the outstanding indebtedness under the Company’s existing mortgage and mezzanine facilities are repaid in full. The Unsecured Term Loan may be prepaid at any time in whole or in part, without any penalty or premium. Amounts drawn under the Unsecured Term Loan and repaid may not be redrawn. The principal amount of loans outstanding under the Unsecured Term Loan bears a base annual interest rate of 6.75%. Accrued and unpaid interest is payable in cash. On December 27, 2017, the Borrower paid to each Initial Lender an upfront fee in an aggregate amount equal to 1.00% of the principal amount of the loan made by such Initial Lender. The Unsecured Term Loan requires that the Company at all times maintain (i) a net worth of not less than $1.0 billion, and (ii) a leverage ratio not to exceed 60.0%. The Unsecured Term Loan includes customary representations and warranties, covenants and indemnities. The Unsecured Term Loan also has customary events of default, including (subject to certain materiality thresholds and grace periods) payment default, failure to comply with covenants, material inaccuracy of representations or warranties, and bankruptcy or insolvency proceedings. If there is an event of default, the lenders may declare all or any portion of the outstanding indebtedness to be immediately due and payable, exercise any rights they might have under any of the Unsecured Term Loan documents, and require the Borrower to pay a default interest rate on overdue amounts equal to 1.50% in excess of the then applicable interest rate. The Company believes it is currently in compliance with all material terms and conditions of the Unsecured Term Loan. The Company incurred $1.8 million of debt issuance costs related to the Unsecured Term Loan which are recorded as a direct deduction from the carrying amount of the Unsecured Term Loan and amortized over the term of the loan. As of March 31, 2018, the unamortized balance of the Company’s debt issuance costs was $1.4 million as compared to $1.5 million as December 31, 2017. Mr. Edward S.
