Basically stating Abigail Johnson (and family) effectively has more than 5% holding....
Is this an additional purchase, or is it a long standing holding that has tipped into notification requirements through restructuring or as part of due diligence during audiit prep for the 10K?
Its unclear. A different Fidelity entity was
reported in Feb 2015 to own 564k shares (7.4% of Tesla) through a Fidelity family holding company. The
current report is for 790k shares (10.1% of Tesla). I don't know if the 2015 holdings are still current. The 2016 report is a trust company that is likely holding assets for other institutional investors. Pyramus holds over $200
billion in assets, so you'll see them as significant stakeholders in pretty much every company on the planet. I don't think it is a big indicator of anything other than significant institutional holdings of TSLA stock. It doesn't represent nearly a large enough percentage of Pyramus assets to require reporting on their end.
I don't think you can assume the 2015 holding is related to the 2016 report, although it is certainly possible that the asset was transferred from one Fidelity holding corp to another.
