Note 5. Investments

The Company considers all highly liquid investments held at major banks, certificates of deposit and other securities with original maturities of three months or less to be cash equivalents.

The Company classifies all of its investments as available-for-sale at the time of purchase because management intends for these investments to be available for current operations and includes these investments on its balance sheet as short-term investments. Investments with original maturities longer than three months include commercial paper, U.S. agency securities, non-U.S. government securities and investment-grade corporate debt securities. Investments classified as available-for-sale are recorded at fair market value with the related unrealized gains and losses included in accumulated other comprehensive income (loss), a component of stockholders’ equity. Realized gains and losses are recorded based on specific identification of each security’s cost basis.

In January 2018, the Company sold all of its available-for-sale investments for proceeds of $23.9 million and realized an insignificant loss on the sale of its investments. The Company reviews its investments quarterly to identify and evaluate investments that have an indication of possible impairment. Gross realized gains and losses were insignificant for the year ended June 30, 2018 and the year ended June 30, 2017. Upon the sale of its available for sale securities, the Company reclassified $77 thousand from other comprehensive income to Other expense, net.

The Company had an investment in a technology company, which had historically been accounted for using the cost method and recorded in Other assets. Subsequent to such company’s initial public offering in October 2017, the Company owned approximately 143,000 shares of such company’s common stock. Considering the liquidity in these shares at the time, the Company reclassified its investment from Other assets to short-term investments. In the fourth quarter of fiscal 2018, the Company sold all of its shares for a proceed of $0.4 million and recognized a loss on the sale of $0.1 million.

The following table summarizes the available-for-sale debt securities that were in a continuous unrealized loss position, but were not deemed to be other-than-temporarily impaired (in thousands):
