en.wikipedia.org/wiki/List_of_Swiss_companies_by_revenue

This section is explicitly described as "Ranked by gross inflow of premiums in 2016." But the company is listed under the old name Zurich Financial Services.

Zurich’s own history states that in 2012 the company changed its name from Zurich Financial Services to Zurich Insurance Group. So for a 2016 insurance ranking, the correct company name was Zurich Insurance Group, not Zurich Financial Services.

The table lists Aargauische Kantonalbank with headquarters in Laufenburg, but the bank’s own disclosures say its seat is in Aarau.

On AKB’s FIDLEG information page, the bank states that it is an autonomous institution under cantonal public law with "Sitz in Aarau" and gives its contact address as Bahnhofplatz 1, 5001 Aarau. AKB also has a page explicitly labeled "Hauptsitz Aarau".

So the location shown in this row is incorrect.

This row places Swiss Air Lines / Swiss International Air Lines in Basel under the headquarters column, but the airline’s own company information points to Kloten.

SWISS’s official company profile lists "Kloten (Zurich) Swiss International Air Lines Ltd., Obstgartenstrasse 25, 8302 Kloten". A Swiss commercial-registry aggregator based on SOGC data likewise states that Swiss International Air Lines AG has its legal headquarters in Kloten.

So the headquarters entry in this row is incorrect.

The page says the 10 largest insurance companies are "Ranked by gross inflow of premiums in 2016", but it lists Winterthur Group as if it still existed as a separate insurer in 2016.

AXA’s own corporate history says:

• 2006: "AXA acquires Winterthur Insurance"
• 2007: "Winterthur Insurance is renamed AXA Winterthur"

That means a 2016 Swiss insurance ranking should not list Winterthur Group as a current standalone company. By then, the Swiss business was operating under AXA Winterthur.
