INVESTMENTS

For the available-for-sale bonds and term notes, the carrying value, plus any unrealized gains or losses, equals the fair value. The unrealized holding gains or losses for the available-for-sale securities are reported in other comprehensive income. The Company accounts for its purchases and sales of investments on the trade date of the investment. The classification of available-for-sale securities is based on management's intention of the use of the investments. The Company used a portion of these investments for its acquisition of Ebuys (see Note 2 for additional discussion on the acquisition of Ebuys).

The following table discloses the major categories of the Company's investments as of the dates presented:
