PENNY SIMMONDS (National—Invercargill): My understanding is also that we are in the final 3 percent of countries to join in implementing MARPOL Annex VI, and given that we have waited this long, it would be useful to know a little bit more about the time frame for implementation. Clearly, it hasn't been something we've wanted to rush into, and so we would hope that the implementation isn't going to impact unduly on the domestic operators and, therefore, our supply chain—so if we could get a little more information about the implementation timing, given that we are at the very end of countries adopting this. Thank you, Madam Chair.
