SLV sells ounces of silver each month to pay for the fund's expenses, and some brokerages report these monthly sales on the 1099-B while others don't.  The sales generate capital gains/losses and reduce your cost basis in the shares that you hold.  You can find a good cost basis calculator for SLV at https://www.costbasistools.com/silver/SLV.php.
