[1] Operating lease obligations have been reduced by approximately $357,000 to reflect sub-lease income. Certain obligations under leasing arrangements are collateralized by the underlying asset being leased.

[2] As of August 31, 2016, total future minimum lease commitments was $120.9 million. The increase during the period ending November 30, 2016 is primarily related to the extension of an existing lease within the Company's Guatemala subsidiary for its Pradera location. The subsidiary signed an extension on November 25, 2016, extending the lease termination date from May 31, 2021 to November 30, 2043. The lease extension included the real property at this location currently used by the Company and added additional square footage in the same shopping center to the lease. This has effectively provided the Company with possession of substantially all of the real property available at that location. The Company plans to expand and upgrade the current warehouse club and parking areas, and improve access into and out from the location.
