Determining correct use of plural/plural possessive apostrophes


When a legal company name contains a plural noun, what are the guidelines for showing possession.  Example:  XYZ Solutions - should this include an apostrophe  or an apostrophe with an s when indicating possession?  XYZ Solutions' standard operating procedures or XYZ Solutions's business license

Style and usage experts disagree.


The FEATURED: WRITING TIPS & TRICKS thread holds a post "Forming Possessives with Plural Nouns Ending in S" that describes the controversy.


Most Americans who went to school between 1960 and 2000 -- and several, but not all, well-respected style guides -- just add the apostrophe --> XYZ Solutions'.


Other style guides -- notably the University of Chicago Press's Chicago Manual of Style -- have recently returned to the style common a century ago. Always add apostrophre plus s --> XYZ Solutions's.


You have to find out which styke manual applies to your writing -- your teacher will tell you or your company may have a policy.  If that doesn't answer the question, pick one and be consistent.

I got an advance copy of Chicago's new style manual the other day and saw that they had gone back to the traditional rule. Interesting. I wonder how long it will take APA to follow suit.

Tolley, are you speaking of the 16th edition (2010) or is Chicago already issuing a 17th edition? I got my 16th last summer and would hate to have to buy another so soon.

This is the 2013 pre-edit. It appears that not much has changed from my first read-through. I make it on the list for some of the cool stuff sometimes.

Where is the apostrophe placed in the use of womens room or childrens toys? Before the "s" or after the "s"?
