Downwithpumpers, they are carrying the bonds at fmv. GAAP will let you do that if they classify the debt instruments as "Available-for-sale securities. Additionally, the unrealized gains should not be shown on the Income Statement, but booked as Other Comprehensive Income. See the equity section of the 6/30/06 statements.
