See Note 4 for further details on the short-term investments held. The other asset above relates to advance payments made to a supplier that were recorded at fair value using the discounted cash flow model (DCF) as of March 31, 2019 and December 31, 2018. The fair value measurements of these advance payments were determined based on significant unobservable inputs, including a discount rate of 15% and the expected time to recovery of the payment. Changes to the inputs described above are not expected to have a material impact on the company’s financial position and results of operations in any given period. See Note 12—Payments to Supplier, for further details on these advance payments.

The following table presents information about the Company’s long-term debt which was carried at amortized cost on the condensed consolidated balance sheet as of March 31, 2019 and December 31, 2018 and indicates the fair value hierarchy of the valuation inputs utilized to determine the approximate fair value.

March 31, 2019			Approximate
Liabilities	Book Value		Fair Value		Level 1		Level 2		Level 3
Current portion of long-term debt	$	2,056	$	2,056		—		2,056		—
Long-term debt, less current portion		12,139		11,850		—		11,850		—
Total	$	14,195	$	13,906		—		13,906		—
December 31, 2018
Liabilities	Book Value		Approximate Fair Value		Level 1		Level 2		Level 3
Current portion of long-term debt	$	1,019	$	1,019		—		1,019		—
Long-term debt, less current portion		13,079		13,035		—		13,035		—
Total	$	14,098	$	14,054		—		14,054		—

The book value of the current portion of long-term debt approximates its fair value due to the short-term nature of the balance. The fair value of long-term debt, less current portion was determined based on a DCF analysis using quoted market interest rates, without consideration of transaction costs, which represents a Level 2 basis of fair value measurement. The counterparty to the long-term debt is a major international financial institution.

The carrying amounts reported in the condensed consolidated balance sheets for prepaid expenses and other current assets, accounts payable, accrued expenses and other current liabilities approximate their fair value based on the short-term maturity of these instruments.

There have been no transfers of assets or liabilities between the fair value measurement levels.
