[1] On October 31, 2016, the contract to sub-lease 2,799 square feet of space to a third party expired. The Company has since occupied all 2,799 square feet of space as an expansion to its Corporate Headquarters and included the additional square feet in the table above.

[2] In January 2017, the Company purchased a distribution center in Medley, Miami-Dade County, Florida. The Company transferred its Miami dry distribution center activities that were previously in the leased facility to the new facility during the third quarter of fiscal year 2017. Some portions of the vacated space were subleased (and subsequently returned to the landlord) while the remainder remains available for sublease.

[3] In June 2017, the Company executed a contract to acquire 233,794 square feet of space for a regional distribution center and parking lot. Delivery date is expected to be March 26, 2018 and June 26, 2018, respectively.

[4] Although the Company's lease agreement for the Trinidad storage and distribution facility expired on August 17, 2017, the Company continues to occupy the space as an agreement for a one-year renewal has been reached with the landlord, pending execution of the contract. The Company has also included this one-year lease as part of the minimum lease commitments.
