How this is counted. One row is one company across every government that names it, and supplier names are typed by hand into agendas, so spellings are merged where only a plural or a written-out “incorporated” differs — never on resemblance. Every figure is therefore a floor. Category is read from the wording of each record, so a contract covering several things sits in whichever one its title leads with. Stated value sums the amounts written on the records and is not a company's revenue.
