Spend is reported income plus in-house expenses across 10 filings. 1 further filing for this client was restated by a later amendment and is left out of every total here. The LDA keeps a separate client record for every registrant that files for a client, so this page adds up 2 records, one per registrant listed below. Records are combined when the client name matches once case, punctuation and endings such as Inc. or LLC are set aside; for a city, county or port the state has to match as well.

 Who filed for this client 2

Spend per registrant: fees an outside firm reported, or the costs the client reported for lobbying in-house. The rows add up to the total above.
