[1] Amounts represent right of use assets and lease liabilities recorded in our Consolidated Balance Sheet in connection with the adoption of Topic 842 on April 29, 2019. These amounts include a right of use asset and a corresponding lease liability totaling $1.1 million that were associated with our former home accessories segment. As disclosed in Note 3 located in the consolidated financial statements, we sold our entire ownership interest in eLuxury on March 31, 2020, and consequently our home accessories segment was eliminated at such time. As a result, there were no right of use assets and corresponding lease liabilities associated with our former home accessories segment as of May 3, 2020.
