Advantage Trust Company builds an initial bond portfolio with staggered maturities and call dates. As each bond matures or is called, a replacement is selected based upon the other existing bond maturities and calls, modified by the then current outlook for interest rates. We invest only in bonds that are rated as “Fiduciary Quality”, are “bank qualified”, or are insured. For those accounts desiring tax exempt income, we also may invest in non-rated, uninsured municipal utility bonds if they have at least a 1 1/4 times debt coverage.
