Reference Page Question Citing Study's Apa format

I cannot for the life of me find how to correctly a study in the Reference section.

I did find this, but it says nothing about reference page formatting other than if it's not a published study. I believe it is since I found it linked in an article that I was reading on the subject matter. In paper citing isn't an issue it's the reference page I'm drawing a blank here. Title page:

January 2011

ERGs Come of Age:
The Evolution of Employee
Resource Groups

A study by Mercer's Global Equality, Diversity, and
Inclusion Practice

Funded in part by
Industrial Relations Counselors
