There are a couple of factors here. One is the demands on the military pension and disability. SISIP and the SISIP disability have been increasing for a number of reasons. I mentioned earlier to Mr. McCauley's question some of the issues around investing in mental health, and supporting mental health is part of that.
The other thing is in the very low interest rate environment that we have now, pension plans have faced some challenges, and we are committed to first of all maintaining the prudential strength of our public pension plans, but also maintaining transparency around our pension plans. This investment reflects that.
I've been informed by my official Brian that there's been a 66% increase in benefits over three years resulting from Afghanistan veterans, as an example. This is something that whatever government was there would be faced with. There's a very real need to maintain the prudential strength of our pension plans during a time when, in the case of SISIP, as an example, payout will grow. We're in a very low interest rate environment. This investment reflects that.
