Thanks, Ari. I'm very excited to share the positive financial results for the fourth quarter of fiscal 2020 ended September 30, 2020, with you this morning. Total revenue for the quarter ended September 30, 2020, which is comprised of license and services revenue was consistent at $2.7 million for the quarters ended September 30, 2020 and 2019.

As a percentage of total revenue, subscription and perpetual license revenue increased 12% to 74% of total revenue for the quarter ended September 30, 2020, compared to 62% for the same period in 2019. This increase is attributed to multiple renewals across the diverse portfolio of customers, including retail, health care, financial services, franchisee, education, manufacturing, and multiyear license renewals from pharmaceutical, industrial manufacturing and global energy companies.
