[1] Operating lease obligations have been reduced by approximately $1.2 million to reflect expected sub-lease income. Certain obligations under leasing arrangements are collateralized by the underlying asset being leased.

[2] Future minimum lease payments include $0.7 million of lease payment obligations for the prior leased Miami distribution center. For purposes of calculating the minimum lease payments, a reduction is reflected for the actual sub-lease income the Company expects to receive during the remaining lease term. This sub-lease income was also considered for the purposes of calculating the exit obligation, which was immaterial as of May 31, 2020.
