[1] In connection with the closing of the Master Modification Agreement and termination of the business management agreement, the Company paid a business management fee for January 2014, which totaled approximately $3,333. The Company did not pay a business management fee subsequent to January 31, 2014. Pursuant to the letter agreement dated May 4, 2012, the business management fee was reduced for investigation costs exclusive of legal fees incurred in conjunction with the SEC investigation (as previously disclosed in the Form 10-Q filed on May 12, 2014). The Master Modification Agreement contained a 90-day reconciliation of certain payments and reimbursements, including the January 2014 business management fee. The reconciliation was completed during the year ended December 31, 2014, which resulted in $728 of SEC-related investigation costs and an adjusted January 2014 business management fee expense of $2,605. Pursuant to the March 12, 2014 Self-Management Transactions, the May 4, 2012 letter agreement by the Business Manager has been terminated
