As we have emphasized, the FAA and other global regulators will determine when the 737 MAX returns to service. However, in order to help our customers and suppliers plan their operations, we periodically provide them with our best estimate of when regulators will begin to authorize the ungrounding of the 737 MAX.

We are informing our customers and suppliers that we are currently estimating that the ungrounding of the 737 MAX will begin during mid-2020. This updated estimate is informed by our experience to date with the certification process. It is subject to our ongoing attempts to address known schedule risks and further developments that may arise in connection with the certification process. It also accounts for the rigorous scrutiny that regulatory authorities are rightly applying at every step of their review of the 737 MAX's flight control system and the Joint Operations Evaluation Board process which determines pilot training requirements.

Returning the MAX safely to service is our number one priority, and we are confident that will happen. We acknowledge and regret the continued difficulties that the grounding of the 737 MAX has presented to our customers, our regulators, our suppliers, and the flying public. We will provide additional information about our efforts to safely return the 737 MAX to service in connection with our quarterly financial disclosures next week.
