Results are similar for management but interestingly, only 4.1% of management (8 of 193) were RA'd. Average age of RA's managers was 57.0 years vs. 47.1 years for managers not affected. Employee to manager ratio (US employees only) fell from 2.4 to 2.1.
In total, 83 of 664 or 12.5% were RA'd. Average age of RA'd employees is 52.4 years vs. 44.7 years for those not affected.

Here's another view of the same data, comparing the % of employee population in each age group to the % of RA'd employees in each group. Again, after age 45 the rate of RA is above the population mix, and after age 55 it is quite disproportionate.
Update July 2, 2013: fixed a couple typos but the story remains the same.
Update July 3, 2013: added chart to compare population mix to RA mix.
