What is the all time high for Zend?

Can you please clarify for me, what exactly is the all-time high value achieved by Zend? Is this referring to the peak market capitalization, the highest trading price, or perhaps some other metric? It would be great if you could provide a specific figure and the date it was achieved, so I can have a better understanding of Zend's performance and potential for future growth. Additionally, it would be interesting to know if there are any notable factors that contributed to this all-time high.
