The Hazard Below is produced and distributed by Apaton Finance GmbH (“Apaton Finance”) of Hanover, Germany, a capital markets communications firm active since 2005. Apaton Finance was engaged by Zefiro under a consulting services agreement that includes production of articles and content based on publicly disclosed information for distribution through German and English language channels, along with research pieces and media production.

Zefiro Chief Executive Officer Catherine Flax commented, “Our team is very excited about working with Apaton, who has done a fantastic job with producing The Hazard Below. This documentary will be instrumental to how we tell Zefiro’s story, which is ultimately about much more than simply plugging oil and gas wells. The big picture of how these wells get left behind and forgotten about provides important context for the persisting environmental hazard of methane leaks and contamination of the water table, and Lyndsay Malchuk articulates quite well how Zefiro fits into that equation as public and private efforts continue to push for the remediation of these environmental liabilities. We are grateful for all of Apaton’s hard work to produce this documentary for Zefiro, and I strongly recommend taking the 25 minutes to watch The Hazard Below for anybody who wants to know more about orphaned oil and gas wells in the United States.”
