Is the last IRSG audit late for Mozilla?

According to https://groups.google.com/d/msg/mozilla.dev.security.policy/IjgFwzGI_H0/OlYp6bspCgAJ an audit reminder was sent about the IRSG root X1. What does that imply?

We recently completed our 2016 audit but there is some delay between when the audit process completes and the auditor makes the letters available. We expect to have them in January. Once we have them we’ll file them with Mozilla. All of this is happening exactly one year after our last audit, it’s not late.

Thank you for the update!
