Spend is reported income plus in-house expenses across 16 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 3 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. These filings have also been reported as COSTAR GROUP.
