The Company only purchases high grade bonds that have a maturity from the date of purchase of no more than two years. The Company monitors the creditworthiness of its investments on a quarterly basis. The Company does not intend to sell the investments and does not believe it will be required to sell the investments before the investments mature and therefore recover the amortized cost basis.
