In terms of further questions, you mentioned that right now you have about 20 assets with icebreaking capabilities, and you usually have about seven deployed in the north. A big part of the conversation is about the north opening up and there being a significant increase in traffic.
Is the ship-building program in place right now for icebreakers designed to essentially replace the existing capacity, or have you made projections about the increasing need for ships as traffic increases? Presumably, there's a need for more assets in order to be able to do the same work for more traffic in the same area.
