How this page counts

Totals combine every contract disclosed under this name, with spellings that differ only in capitals or punctuation counted together. Other names are combined only after review, so one business can have more than one page. A contract re-listed across disclosure files counts once, at its highest value, where the files give a contract reference; older disclosures are counted as published, so totals are upper bounds. Award lines are shown as published. Figures are indicative and subject to revision.
