[1] | (1)Impairment charges are primarily resulting from our landlord’s sale of a restaurant property to a franchisee.
[2] | (2)Qdoba Evaluation consulting costs are primarily related to third party advisory services.
[3] | (1)Year-to-date 2018 includes a reduction in severance and related costs due to a change in the number of employees to be terminated in connection with our restructuring activities.
[4] | (2)The weighted average remaining lease term related to these commitments is approximately 4 years.
[5] | (3)This balance excludes $3.2 million of restaurant closing costs that are included in accrued liabilities and other long-term liabilities on our condensed consolidated balance sheets, which were initially recorded as losses on the sale of company-operated restaurants to Jack in the Box franchisees.
[6] | (1)Adjustments relate primarily to revisions of certain sublease and cost assumptions. Our estimates related to our future lease obligations, primarily the sublease income we anticipate, are subject to a high degree of judgment and may differ from actual sublease income due to changes in economic conditions, desirability of the sites and other factors
