This Act applies to all classes and kinds of insurance which may be written by stock or mutual casualty insurance companies, associations or exchanges, and including fidelity, surety and guaranty bonds and all other forms of motor vehicle insurance, and to title insurance on risks or operations in this Commonwealth except:
If any kind of insurance, subdivision or combination thereof, or type of coverage, subject to this Act, is also subject to regulation by another rate regulatory act of this Commonwealth, an insurer to which both acts are otherwise applicable shall file with the Commissioner a designation as to which rate regulatory act shall be applicable to it with respect to such kind of insurance, subdivision or combination thereof, or type of coverage.
