While its facilities generally remain open, the Company is making extensive use of the work-from-home model at this moment. On a daily basis, management is reviewing the Company's operations and there have been to date minimal interruptions in the Company's customer facing operations. Given the digital nature of the Company's business and the move toward cloud enablement, the Company expects to remain operationally stable and fully available to its customers. The Company is in compliance with all financial covenants and has not observed a loss of any significant customers, a significant deterioration in the collectability of receivables, a significant reduction in its liquidity nor a significant decline in subscription renewal rates.
