Company is just a portfolio of 1 year adjustable rate federally guarenteed securities. There is no default risk and basically no interest rate risk, like a TIP treasury. Only risk to stock is irrational selling waves. Dividend is just essentially government bond payments that vary with short term interest rate, so totally secure with some up and down variation. Book value is just liquidation value of the government bonds, so totally secure. Sell away !!! Buy CAT !!
