This article is horribly out of date. If anyone has access to the updated information it would be appreciated

Company names
Per Wikipedia's manual of style, company names should generally be in "mixed case" (not all caps) and they should not have descriptors like "Inc", "Corp", "LLC", etc.

If a page exists an the wrong name, move it.

Red-links
If a page does not exist in any location, either dewikilink it or leave a redlink, but be consistent throughout this list. Given that all or almost all companies on this list probably meet one of Wikipedia's relevant notability guidelines, it's probably safe just to use red-links throughout. davidwr/ (talk)/(contribs)  03:03, 28 December 2013 (UTC)

Constituents with a company name that begins with 'The'?
Anyone have any thoughts on the below constituents and their company names? Should we remove the 'The' at the front and put at the end like '(The)'? Or just remove the 'The' altogether? It does create a small problem when sorting the 'Company' column and these 5 companies sort together.Ksu6500 (talk) 21:57, 5 January 2017 (UTC)

Re-alphabetize
I am starting the process so that the primary sort order in the list table is the company name, not the ticker; this will conform it to List of S&P 500 companies. Help appreciated! UnitedStatesian (talk) 15:46, 25 April 2017 (UTC)

Duplicate entries in List of S&P 500 companies and List of S&P 400 companies
There are 12 companies that are currently in both the List of S&P 500 companies and the List of S&P 400 companies:

ATO	Atmos Energy -- BIO	Bio-Rad Laboratories -- CTLT	Catalent -- DPZ	Domino's Pizza -- ETSY	Etsy -- POOL	Pool Corporation -- ROL	Rollins Inc. -- TDY	Teledyne Technologies -- TER	Teradyne -- TYL	Tyler Technologies -- WRB	W.R. Berkley Corporation -- WST	West Pharmaceutical Services

They should be in one or the other, I think. I don't have the definitive source lists, so I don't know which should be deleted from one of these lists.

After deleting them, there most-likely will be missing ones that are in the source lists from one or both of these lists. I'm guessing there should be 500 and 400 in each.

Also, there was a transaction this year whereby CZR and ERI in this List of S&P 400 companies now point to the same company at the SEC: Caesars Entertainment, Inc. So, something is probably wrong.

I removed these 12 companies, to make this list more accurate.
