Thank you for the question.
To begin, we tried to minimize the scope of the change by using a number of existing modules. There were five phases. Later on, new models will be forthcoming.
As to the contingency plans, some of the concerns raised might materialize during the transition. There will be a 16-day transition period during which we will make a copy of the old system and deactivate it, and then activate the new system.
One scenario is that it could take too long to transfer the data and we could exceed our one-day deadline. In that case, our contingency plan is to inform all parties that if it is not done on May 13, it will be done on May 14. That's okay.
A second possibility is that a module might not work. We also have a contingency plan for that. So let's say we have only been able to transfer 5% of the data after 10 days, which would be a major problem, our contingency plan would be to reactivate the old system. So we are prepared for a range of possibilities.
We also have contingency plans for situations that might arise after the system has been launched, specifically confusion at the border. We have said that we will not be changing the current processing system at the border, only the accounting system. If people have questions, we will have employees on site to answer them.
In short, we have several levels of contingency plans to respond to various potential scenarios.
