I would say that the e-mail system is out of the gate first, and it will generate a significant savings as early as 2015. Proportionately you might say it's a large savings because it's about $55 million out of an original spend of somewhere between $104 million and $124 million, depending on whether you're counting all of the IT security that goes along with it, so it's a big proportion.
However, the data centre consolidation, as Mr. Long mentioned, will also generate a $99-million per year savings over time, but on a bigger base. The one thing that I would mention about that, Mr. Chairman, is that it's generating a $99-million saving even as it is increasing storage by seven times, sevenfold, even as the security posture of those data centres is increased, so it's hard to do apples to apples in these sorts of calculations.
