So that means that the next one will be a 10K (annual).
The 10K for 2018 came out Mar 5 2019, so I would expect the 2019 10K to come out around the same time.
The January delivery #s should be coming out in the next few days, but with the coronavirus shutting down the manufacturing plant for at least 2 weeks, I don't think that the #s will be that good.
