How to list on resume

Drovor

I started out working as a contractor for 2 years at my current job. Then we were moved to a 2nd contractor for a year. Now I am working for an outsourcing company full time but still the same position. How would I go about listing my current job? Would I need to split it up?

Currently I use the following and never incorporated the outsourcing company. During the initial phone interviews I explain in detail just to make sure it is clear.

Company I work at (contractual), City, CA
