Reports posted after the due date

The Lobbying Disclosure Act asks each registrant to file a report for each quarter no later than 20 days after the quarter ends (2 U.S.C. 1604(a)): by January 20, April 20, July 20 and October 20. We compare the date LDA.gov gives as the report's posting with the due date. When the 20th falls on a Saturday, a Sunday or the Martin Luther King Jr. holiday, we count the next business day as the due date. An amendment to a report is not counted. A report posted after the due date is listed with the number of days after it.
