Severance and restructuring accruals: In connection with the abandonment of our Newark, California facility following the closing of the sale of the Digital Products Business, we accrued for the remaining lease costs through the lease termination in May 2016. In December 2015, we entered into an agreement to terminate this lease and related obligations, including AROs, as of February 2016 for a payment of $0.2 million. As a result of the agreement, we recorded a gain of $0.3 million on the lease termination. The resulting gain was recorded in the discontinued operations of the Digital Products Business for the fiscal year ended September 30, 2016. See Note 5 - Discontinued Operations.

On June 7, 2016, the Company's former Chief Financial Officer (“CFO”) notified the Company that he would resign as the Company's CFO, effective as of June 20, 2016 (the “Separation Date”). The Company and the former CFO entered into a separation agreement and general release, dated June 7, 2016 (the “Separation Agreement”), which includes mutual releases by the former CFO and the Company of all claims related to his employment and service relationship with, and termination of employment and service from, the Company. The Separation Agreement provides for, among other things, the continuation of his base salary for 64 weeks, benefits for 16 months, outplacement services for a period of not more than 1 year and with a value not in excess of $15,000 and immediate vesting of all his outstanding non-vested equity awards, other than his most recent equity award. These payments are not contingent upon any future service by the former CFO. The Company recorded a charge of approximately $0.4 million in the fiscal year ended September 30, 2016 related to this Separation Agreement.

In an effort to better align our current and future business operations, in May 2016 the Company announced a reduction in its workforce by approximately 30 individuals and recorded a charge for severance for the affected employees in the amount of $0.3 million in the fiscal year ended September 30, 2016. In November 2016, the Company announced an additional reduction in the workforce of approximately 5 individuals and recorded a charge of $0.2 million in the fiscal year ended September 30, 2017 related to the outsourcing of our satellite communications assembly operations.

In March 2017, the Company announced an additional workforce reduction of approximately 14 individuals and recorded a charge of $0.1 million in the fiscal year ended September 30, 2017 related to the outsourcing of a portion of our wafer fabrication lab. During the fiscal year ended September 30, 2017, the Company recorded an additional charge of $0.4 million for six additional individuals related to the March 2017 workforce reduction. Also, in March 2017, in connection with our anticipated opening later in fiscal year 2017 of a new manufacturing facility in China to reduce costs and improve efficiency, we accrued for a workforce reduction of approximately 265 individuals and recorded a charge of $0.5 million in the fiscal year ended September 30, 2017. During the fiscal year ended September 30, 2017, the Company recorded an additional charge of $0.4 million for the workforce reduction of 72 additional individuals related to the opening of our new manufacturing facility in China.

In September 2017, the Company announced it would close its Ivyland, Pennsylvania location during fiscal year 2018 and reduce its workforce by approximately 11 individuals and recorded a charge for severance for the affected employees in the amount of $0.3 million in the fiscal year ended September 30, 2017.

In connection with the closing of the Ivyland, Pennsylvania location in January 2018, we accrued for the remaining lease costs of the facility through the lease termination of February 2019. Included in selling, general and administrative expense for the fiscal year ended September 30, 2018, was $0.2 million related to the remaining lease costs.

In March 2018, the Company announced an additional workforce reduction of approximately 21 individuals to better align our workforce towards our Chip Devices and Navigation Systems product lines and away from Broadbrand product lines and recorded a charge of $0.4 million in the fiscal year ended September 30, 2018.
