For the periods presented, gains or losses realized on the sale of investments were not material. Investments are reviewed periodically to identify possible other-than-temporary impairments. As the Company has the ability and intent to hold these investments with unrealized losses for a reasonable period of time sufficient for the recovery of fair value, which may be maturity, the Company does not consider these investments to be other-than-temporarily impaired for any of the periods presented.

The amortized cost of investments classified as cash equivalents approximated the fair value due to the short-term nature of the investments.

The contractual maturities of the Company's short-term and long-term investments as of September 30, 2019 are as follows (in thousands):
