years ago (2007) I worked on a plan that we did some preliminary testing.
one individual owned exactly 5% and was deferring 15%. Based on whatever data they sent- maybe it was 9 months of comp,
their projected comp was 100,000.14
I told them I don't care how they handle it, just make sure that the person's comp did not go over the 100,000, even if the person comes to work in the morning and finds 14 pennies sitting on his desk one day.
