The same problem, on a smaller scale, faces practically every company trying to develop new products and create new jobs. There can be little prospect of raising the sort of sums require from friends and people we know, and while banks may agree to provide short term finance, they are generally unwilling to provide money on a permanent basis for long-term projects.

Thus they do by issuing stocks and shares in the business through the Stock Exchange. Only by doing so can they put into circulation the savings of individuals both at home and abroad. When the saver needs his money back, he does not have to go to the company with whom he originally placed it.

In one way or another, the money needed must be gathered from the public at home or abroad. The Stock Exchange exists to supply a channel through which these savings can reach those who need finance. Almost all companies involved in new production and development must ______.
