9. Senior Convertible Notes and Warrants

On December 17, 2019, the Company completed the issuance and sale of $3,000 aggregate principal amount of secured convertible notes of the Company (the “Notes”) and warrants (the “Warrants”) to purchase 340,909 shares of common stock, par value $0.001 per share of the Company (the “Common Stock”), in a private placement transaction. The Notes and Warrants were issued and sold to Edward D. Bagley, an affiliate of the Company, on the terms and conditions of a Note Purchase Agreement dated December 8, 2019 between the Company, certain subsidiary guarantors of the Company, and Mr. Bagley. Mr. Bagley is an affiliate of the Company and was the beneficial owner of approximately 46.6% of the Company’s issued and outstanding shares of Common Stock.

The Notes will mature on December 17, 2023 (the “Maturity Date”) and will accrue interest at a variable rate adjusted on a quarterly basis and equal to two and one-half percent (2.5%) over the greater of (x) five and one-quarter percent (5.25%) and (y) the Prime Rate as published in the Wall Street Journal (New York edition) as of the beginning of such calendar quarter. The Notes may be converted into shares of the Company’s Common Stock at any time at the election of Mr. Bagley at an initial conversion price of $2.11 per share (the “Conversion Price”), or 120% of the closing price of the Common Stock on December 6, 2019 as reported on the Nasdaq Capital Market. Also, the Company can cause a mandatory conversion of the Notes if the volume weighted average closing price of the Common Stock over 90 consecutive trading days exceeds 200% of the Conversion Price. In addition, the Notes may be redeemed by the Company for cash at any time after December 17, 2020 upon payment of the outstanding principal balance of the Notes and any unpaid and accrued interest. The Company also is required to redeem the Notes upon the occurrence of a change in control of the Company.

The Warrants have an initial exercise price equal to $1.76, the closing price of the Common Stock on December 6, 2019 as reported on the Nasdaq Capital Market, and are exercisable until December 17, 2026. The Warrants must be exercised for cash, unless at the time of exercise there is not a then effective registration statement for the resale of the shares of Common Stock issuable upon exercise of the Warrants, in which case the Warrants may be exercised via a cashless exercise feature that provides for net settlement of the shares of Common Stock issuable upon exercise.

Concurrent with the issuance of the Notes and Warrants pursuant to the Note Purchase Agreement, the Company, the Guarantors and Mr. Bagley entered into a Guaranty and Collateral Agreement (the “Collateral Agreement”) pursuant to which the Company and the Guarantors granted Mr. Bagley a first priority lien interest in all of the Company’s assets as security for the Company’s performance of its obligations under the Notes and Warrants.

The net proceeds after original issue discount and issuance costs of $346 were approximately $2,654. The Company expects to use the proceeds from the sale of the Notes and Warrants for general corporate purposes and working capital.

In accounting for the issuance of the Notes, the Company separated Notes and Warrants into liability and equity components. The carrying amount of Warrants, being an equity component, was first calculated using Black-Scholes method with the following assumptions:

Risk-free interest rate	1.82%
Expected life of Warrants (years)	7
Expected price volatility	49.94%
Expected dividend yield	0%

The carrying amount of the Notes was then determined by deducting the fair value of the Warrants from the principal amount of the Notes. The carrying amount of the Notes was further separated into equity and liability components after separating the value of the conversion feature into an equity component and leaving the remaining value as liability. The equity component is not remeasured while the Notes and Warrants continue to meet the conditions for equity classification for equity components.

The original issue discount and issuance costs are netted against the liability. The following table represents the carrying value of Notes and Warrants:

	December 31, 2019			December 31, 2018
Liability component:
Principal	$	3,000		$	—
Less: debt discount and issuance costs, net of amortization		(778	)		—
Net carrying amount	$	2,222		$	—
Equity component⁽¹⁾:
Warrants	$	318		$	—
Conversion feature		122			—
Net carrying amount	$	440		$	—

(1) Recorded on the consolidated balance sheets as additional paid-in capital.

Debt discount and issuance costs are amortized over the life of the note to interest expense using the effective interest method. During the year ended December 31, 2019, amortization of debt discount and issuance costs was $8. The following table represents schedule of maturities of principal amount contained in the Notes as of December 31, 2019:

Year ending December 31,	Principal Amount Maturing
2020	$	—
2021		360
2022		720
2023		1,920
Net carrying amount	$	3,000
