Spend over time
Every filing period on record, as reported. One column per filed period — a period with no column is a period with no filing, not a zero.
Basis · Amendments and terminations supersede the original report for the same registrant, client and period, so a revised quarter is counted once at its latest filed value. Registration-only filings carry no activity money and are excluded from these totals.
Who lobbies for them
Every outside firm that has filed on this client's behalf, by fees reported.

Note · A filing names one to several issue areas and reports a single dollar figure for the period, so the same money appears beside every issue that filing declares. The dollar column is therefore spend on filings that named this issue — it is not a split of the total, and these figures sum above it. Filing counts do not double-count.

The filings
Every filing on record. Each row links to its full disclosure.
This record groups every filed spelling of the client's name into one entity, so "MERCK & CO., INC." and "MERCK & CO INC" read as the same company. The grouping is the client's normalized name — organizations that file under genuinely different names appear separately. Handle: mathematica-inc.
