We provide long-term incentives to eligible officers, directors, and employees in the form of equity-based awards. We maintain four equity incentive compensation plans, collectively described below as our “Equity Plans”:

We issue new shares of common stock to satisfy awards issued under our Equity Plans.

401(k) Plan

We have a savings plan that qualifies as a deferred salary arrangement under Section 401(k) of the Internal Revenue Code. Under this savings plan, participating employees may defer a portion of their pretax earnings, up to the Internal Revenue Service annual contribution limit. Since June 2015, all employer contributions are made in cash. During each of the three months ended June 30, 2020 and 2019, our matching contribution in cash was approximately $0.2 million. Our matching contribution in cash for the nine months ended June 30, 2020 and 2019 was approximately $0.7 million and $0.4 million, respectively.

Loss Per Share

The following table sets forth the computation of basic and diluted net loss per share:


	For the three months				For the nine months
Basic and Diluted Net Loss Per Share	ended June 30,				ended June 30,
(in thousands, except per share)	2020		2019		2020		2019
Numerator:
Loss from continuing operations	$	(1,287)	$	(10,477)	$	(7,703)	$	(21,009)
Undistributed earnings allocated to common shareholders for basic and diluted net income per share		(1,287)		(10,477)		(7,703)		(21,009)
Denominator:
Denominator for basic and fully diluted net loss per share - weighted average shares outstanding		29,295		28,005		29,052		27,730

Net loss per basic and fully diluted share	$	(0.04)	$	(0.37)	$	(0.27)	$	(0.76)

Weighted average antidilutive options, unvested restricted stock units and awards, unvested performance stock units and ESPP shares excluded from the computation		1,410		1,317		1,316		881

For diluted loss per share, the denominator includes all outstanding common shares. The anti-dilutive stock options and unvested stock were excluded from the computation of diluted net loss per share for the three and nine months ended June 30, 2020 and 2019 due to the Company incurring a net loss for the periods.

Employee Stock Purchase Plan

We maintain an Employee Stock Purchase Plan (“ESPP”) which provides employees an opportunity to purchase common stock through payroll deductions. The ESPP is a 6-month duration plan with new participation periods beginning on approximately February 25 and August 26 of each year. The purchase price is set at 85% of the average high and low market price of our common stock on either the first or last trading day of the participation period, whichever is lower, and annual contributions are limited to the lower of 10% of an employee’s compensation or $25,000.
