Should a c# class generate instances of itself?

I have a class that defines a CallRate type. I need to add the ability to create multiple instances of my class by reading the data from a file.

I added a static method to my class CallRate that returns a List<CallRate>. Is it ok for a class to generate new instances of itself by calling one of its own constructors? It works, I just wonder if it's the proper thing to do.

List<CallRates> cr = CallRates.ProcessCallsFile(file);
