Source: quarterly LD-2 disclosures filed under the Lobbying Disclosure Act. A fee covers everything the firm did for that client in the period, so it cannot be attributed to any one issue on the list. A filing that states no figure contributes nothing rather than a zero. Clients with no ticker are kept: a trade association or a foreign ministry is as much a part of what the firm does as a listed company.
