Under Armour, Inc. (UAA): Weighted Average Diluted Shares

Annual figures by period end, from SEC filings.

Stock splits: 2-for-1, first reflected in a filing dated 2012-08-06; 2-for-1, first reflected in a filing dated 2014-05-07. Figures are as filed: per-share figures and share counts last reported before a split are on the old share basis, so changes and growth rates across a split are not shown. Splits are read from the filings' own restatements, so a share conversion in a merger or reorganization shows up the same way.

Figures left out. The filed Weighted Average Diluted Shares for the year ended 2008-12-31 is not shown: share count out of scale with net income per share. That usually means the filing tagged the figure in the wrong unit.
