[1] The reductions are primarily due to historical failed sale leaseback and build to suit arrangements where we were deemed owner for accounting purposes. In accordance with ASC 842 transition provisions, they became operating or finance leases.

[2] The increases include land and other operating leases which were not previously recorded on our balance sheet or were previously recorded as financing obligations.

[3] The reductions are primarily due to the reclassification of lease-related assets and liabilities such as straight-line rent and reserves for closed stores to operating lease assets and liabilities.

[4] The cumulative effect of lease adjustments, net of the deferred tax impact, was recorded as an adjustment to retained earnings.  In addition, retained earnings include a $26 million lease impairment charge.
