Berkshire Hathaway Inc, a 10%+ owner of Sirius XM Holdings Inc. (SIRI), reported buying 924,281 shares of common stock for about $26.9 million in three reported transactions dated Oct. 30 to Nov. 3, according to a Form 4 filed Nov. 3.

Each of the three lines is a weighted average of several trades. Prices paid ran from $28.655 to $30.51 a share, and Berkshire's average price across the purchases was $29.10.

On Oct. 30, Berkshire bought 743,965 shares at a weighted average price of $28.8913, in trades from $28.655 to $29.01, worth about $21.5 million. On Nov. 2 it bought 66,968 shares at a weighted average price of $29.466, in trades from $29.34 to $29.51, for roughly $2 million. The Nov. 3 purchase covered 113,348 shares at a weighted average price of $30.233, in trades from $29.85 to $30.51, worth about $3.4 million.

A Form 4 is the report that officers, directors and holders of more than 10% of a company's stock must file within two business days of a trade in its shares. Transaction code P marks an open-market or private purchase paid for by the insider, as opposed to grants, option exercises or employee-plan purchases; the code is explained here.

All three lines report the holding as indirect. Before the first purchase, Berkshire's indirect holding stood at 124,807,117 shares. After the Nov. 3 purchase it was 125,731,398 shares, a 0.7% increase. The filing gives the holding after each line: 125,551,082 shares following Oct. 30 and 125,618,050 following Nov. 2.

The Oct. 30 purchase was filed four calendar days later, or two weekdays. The Nov. 2 purchase was filed one day after the trade.

Between July 23 and the Form 4s filed before Nov. 1, no open-market purchases by Sirius XM insiders were filed. One open-market sale was filed in that span: director Jonelle Procope sold 16,672 shares on Aug. 6 for about $499,702, 85 days before Berkshire's first reported purchase.
