APA reference format for encyclopedia entry with no author only an editor?

How do you format a reference in APA for an encyclopedia entry with only an editor and no author. Here is what I have to put in the correct order. I've searched for an example but do not see one that specifically explains this.

Encyclopedia entry:
Business plans. (2005). In M. Warner (Ed.), International encyclopedia of business and management (Vol 1, pp. 20-21). London: Routledge.
