Smiths Detection is responsible. Again, they're our contractor and our devices are used by them. Our employees are expected to follow the regular maintenance schedule. If there are malfunctions within our devices, we would send them back to the manufacturer or for routine maintenance.
In fact, as part of the review that took place, we are in the process right now of finalizing a contract with Smiths Detection to incrementally take all of our machines that are currently in service and send them to them for a review to ensure that they're all functioning properly. If there are any maintenance issues or what have you to be improved upon, it will be done at that time.
