W. R. Berkley Corp (WRB): Weighted Average Diluted Shares

Annual figures by period end, from SEC filings.

Stock splits: 3-for-2, first reflected in a filing dated 2019-05-08; 3-for-2, first reflected in a filing dated 2022-05-03; 3-for-2, first reflected in a filing dated 2024-08-02. 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 years ended 2019-12-31, 2020-12-31, 2021-12-31, 2022-12-31 are not shown: share count out of scale with net income per share. That usually means the filing tagged the figure in the wrong unit.
