This excerpt taken from the SIRI DEF 14A filed Apr 20, 2005.
During the year ended December 31, 2004, there were 12 meetings of our board of directors, and the board took action once by written consent in lieu of a meeting. Each director attended more than 90% of the total number of meetings of the board and meetings held by committees on which he served. Directors are encouraged to attend the annual meeting of stockholders, but our board of directors does not have a formal policy with respect to attendance. Messrs. Clayton and Gilberti attended and participated in our 2004 annual meeting of stockholders.
