To make the site structure more logical and coherent, each page in the site is assigned to a category. For example pages talking about policies are in Policies –category, pages talking about instruments are in Instruments –category and pages talking about individual products are in Products –category.
The categorization is hierarchical. All pages in Policies belong to category Policies and instruments and so on.
This is a category for pages talking geographical subregions. This is lowest category in the category places
