First of all it's a mix. There's a bit of both. Some has to do with replacing them; some has to do with acquiring them.
I'll start with that last part by way of example. For data-analytic types of software, it's having enough people to fully run them. This is directly for audit operations, even though we have also used it internally to do good management analysis of our own spending, let's say, and things such as that, but it's mainly for audit operations. We have some software that has to do with learning and development, such as training in the office. Again, most of our staff are in audit operations, so we're talking about impact on audit operations.
When we do business with an audited entity, we need to exchange information—get information from them and capture it in an automated way to bring it into the audit tool and make it more efficient and simpler for everybody. It's being able to directly, electronically draw from them rather than do paper analysis.
Those are a few examples.
