Investments

Investments in certain securities may be classified into three categories:

·

Held-to-maturity - Debt securities that the Company has the positive intent and ability to hold to maturity are reported at amortized cost.

·

Trading securities - Debt and equity securities that are bought and held principally for the purpose of selling in the near term are reported at fair value with unrealized gains and losses included in earnings.

·

Available-for-sale - Debt and equity securities not classified as either securities held-to-maturity or trading securities are reported at fair value with unrealized gains or losses excluded from earnings and reported as a separate component of stockholders’ equity.

The Company reassesses the appropriateness of the classification of its investments at the end of each reporting period. The Company has determined that its debt securities should be classified as held-to-maturity as of December 31, 2015. There were no investments as of December 31, 2016. This classification was based upon management’s determination that it has the positive intent and ability to hold the securities until their maturity dates, as all of the investments mature within 6 months and the underlying cash invested in these securities is not required for current operations.

Investments consist of short-term FDIC insured certificates of deposit, commercial paper rated A1/P1 or above and corporate notes and bonds rated A and above carried at amortized cost using the effective interest method.

The following summarizes information about short-term investments at December 31, 2016 and 2015:

	Amortized Cost		Gross Unrealized Losses		Estimated Fair Value
2016
Certificates of deposit, commercial paper	$	—	$	—	$	—
2015
Certificates of deposit, commercial paper	$	6,689,643	$	4,948	$	6,684,695

As of December 31, 2015, the estimated fair value of the investments was less than the amortized cost. Because management intended to hold the investments until their maturity dates, these unrealized losses were not recorded in the consolidated financial statements.

The maturities of held-to-maturity investments at December 31, 2016 and 2015, respectively were as follows (in thousands):
