[1] On June 2, 2019, the Company elected the modified retrospective method of transition to adopt the new lease standard Topic 842, which resulted in no restatement of prior period results. At June 1, 2019, prior to adoption of the new lease standard, operating lease obligations were not included as a liability on the balance sheet. Therefore, the operating lease obligations were included in the table for comparative purposes only and the total lease liability was not included as it is not applicable.
