What this measures
Obligations are the dollars the federal government has committed to a contractor under awarded contracts in a fiscal year. In plain English: it's a leading read on a company's government revenue — a defense prime whose obligations are climbing is winning more work. Figures are summed across each company's contracting subsidiaries (e.g. Sikorsky rolls up to Lockheed Martin) for U.S. contracts only (not grants or loans). Coverage is a curated set of major public federal contractors, so a company not listed here may still contract federally at smaller scale. Source: USAspending.gov (public).
