Investments are difficult to attribute to each of the available selling channels, and therefore difficult to calculate. Also, some borders, like those in the European Union, have disappeared from a taxation point of view, and no longer provide information on trade within the European Union. Also, the new technology will introduce challenges with respect to the measurement of a product's life cycle, with the raw materials being electronically purchased from one country, primary production taking place in another, the components of a product then being transferred to another location for assembly, and then shipped to another location for storage and eventual dissemination. Internet sales administration might take place in an entirely difference location. Providers are already offering free access to Internet and may soon be providing free computers.
Costs are to covered by the income from advertisements or the selling of customer profiles.
These are some of the challenges facing us for the next three days. I would like to raise a final point.
