I believe the last time we looked at this issue was in 1991, so I'd have to go back into all of the details of that.
In the audit that we presented here, we did provide five years of information about the ability of taxpayers to reach an agent, and in 2012-13 it was about 37% and in 2016-17 at 32%. So over the last five years, certainly, the ability of people to reach an agent has been at roughly the same place. Actually, during that time period, in the intervening three years, there were years when it was even worse. In 2015-16, it was only 19% and that improved slightly in 2016-17, but overall, it has been in the range of 37% or less for the last five years.
