I'll address that question.
When it comes to the validation of the 737 Max, the national aircraft certification team within civil aviation, which is led by Dave, will complete its full review. They will provide the recommendation and the assessment against our regulations of whether the aircraft meets the minimum expectations that we have, which are outlined in both regulations and standards. Mr. Turnbull will make a decision on whether to validate that aircraft, at which point we will notify the state authority that certifies the aircraft, as well as the operator.
