I'll answer the first part of the question and then ask my colleague to answer the latter portion of it.
The spend on the internal services is $831 million, and $353 million of that is in relation to our IT function. That said, the IT spend is not obviously all in relation to these investments. Some of the funding in relation to these investments is part of that $353 million. Other funding you would see in what we call the vote 5 or capital vote, obviously in our capital expenditures. You will see a lot of that investment made in our systems appearing there.
We've been spending approximately $100 million a year in the last few years on our investments in relation to the upgrades to these systems.
