It does - check with Sikorsky who will provide you with the engine reliability data (revised data for all types has recently been issued).
They will also provide you with the EHA Risk Assessment that established that if the engine reliability meets a target of 1 x 10^-5, the 5 x 10^-8 is achieved for each take-off or landing event.

Perhaps I should also have added that there is no such thing as a Performance Class 2 helicopter. A helicopter certificated in Category A can be operated in Performance Classes 1, 2 or 3 depending upon the operational requirements.
