* Avg. Buy Price is an estimated cost basis: the share-weighted average of the quarter-end prices reported when this manager first bought or later added to the position (average-cost method, reset after a full exit). 13F filings disclose only quarter-end holdings, not actual trade prices, so this approximates — but does not exactly equal — what was paid.
