Mr. Russell, it's not only the method of transportation but it's the infrastructure on the ground. In terms of the infrastructure investment that we have in the 69 communities that we operate in, our net book value of those assets is $76 million. In those markets, we'll spend $15 million every year in capital expenditure and we'll invest about $3 million in new housing or renovated housing for our staff.
So it's not just the shipping method. We can't, overnight, grow and expand the size of our footprint. We will; we'll continue our capital investment expenditure, and the Nutrition North program will act in many ways as an inducement for further investment by northern-based retailers to grow their plants.
We would obviously like, given all the good points that Andy said.... Take heat and electricity; I don't know what it costs everybody else, but in the communities we're affected by, it's a bill of $10 million a year. Our paying that $10 million allows the rest of the infrastructure in those smaller communities to be supported.
To answer your question, we will ship more product by sealift, but hopefully the northern retailers want to keep the economy vibrant and growing in the north. Our role is to make sure more customers are induced to spend money in the north rather than seeking the product elsewhere.
So the answer is that we're going to do our best to put money, investments, capital expenditure, inventory and assets, and hard infrastructure on the ground in order to bring more product to the north, totally. We never ship tires or spare parts or snowmobile parts. We've never engaged in that business. That wasn't part of our game plan.
In terms of more air shipment, if we work together with INAC, the air carriers, and other retailers, if we focus that air freight on perishable goods, we can do a better job. To tell you the exact impact, bottom line for the customer, I don't think any of us have the total knowledge to do that, but we think we can make a good program here.
