I think that we had already changed by 2016. We operate under our global and national code of conduct, which is our responsible tax practice. Some of the highlights from that responsible code of conduct are that we act lawfully and with integrity and that we provide clients with the highest quality of tax advice.
When we look at the lens from 20 years ago, the lens that we looked through was legality, and it was looking at GAAR. Since then and since the mid-2000s, we've added the additional lens of responsible tax. The tax landscape and social acceptances have changed greatly over the last 20 years.
You can also see it through a great deal of legislation that's been put in place, not just in Canada but globally as well, including Sarbanes-Oxley and the FIN 48 legislations. There was the global financial crisis, which impacted us greatly. The common standards reporting was introduced as well. There's been quite a bit that's changed with respect to transparency, which has very much changed the social landscape and what's acceptable.
