Highly Compensated Employees, Forms of Pay, and Implementation Time

WHD proposes a significant increase to the HCE threshold, raising it from $100,000 to $147,414.
1.What positions in your industry / location are likely to be impacted (i.e., would lose exempt status or be required to move to more than $147,414)?
2.It is virtually certain that the HCE level will increase.  If $147,414 is too high, is there a figure between $100,000 and $147,414 that would limit the operational impact of any change?
