The following table presents the contractual maturities of the Company's available-for-sale investments:

The Company’s available-for-sale securities are liquid and may be sold to fund future operating needs. As a result, the Company recorded all of its available-for-sale securities, not classified as Cash equivalents, in Short-term investments regardless of the contractual maturity date of the securities.
