[1] | (1)Impairment charges are due primarily to our landlord’s sale of a restaurant property to a franchisee.
[2] | The weighted average remaining lease term related to these commitments is approximately 2 years.
[3] | Adjustments relate to revisions to certain sublease assumptions due to changes in market conditions and includes interest expense.
[4] | (1)Qdoba Evaluation consulting costs are primarily related to third party advisory services.
[5] | (2)2018 reflects 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.
[6] | ____________________________(1)Adjustments in accrued severance costs are the result of the change in number of employees to be terminated in connection with our restructuring activities.
[7] | (2)The weighted average remaining lease term related to these commitments is approximately 4 years.
[8] | (3)This balance excludes $2.8 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 upon sale to Jack in the Box franchisees in prior years.
[9] | (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
