Restructuring liabilities at September 30, 2019 of $2.1 million relate to severance and benefits obligations and are recorded in “Other accrued liabilities” in the accompanying condensed consolidated balance sheets.

The Company recorded $6.1 million of restructuring charges, net of reversals and impairment during the three months ended September 30, 2019, including charges of $3.9 million of impairment of right-of-use-assets related to facilities which the Company has exited and $2.2 million related to employee severance and benefit expenses.

During the first quarter of fiscal 2020, the Company continued its initiative to realign its operations by exiting a floor of its San Ignacio building in South San Jose California and consolidating its workforce. Also, the Company exited additional space in its Salem New Hampshire facility which includes general office and lab space. The Company has the intent and ability to sub-lease these facilities which it has ceased using and as such has considered estimated future sub-lease income based on its existing leases agreement, as well as the local real estate market conditions in measuring the amount of asset impairment. The Company also factored into its estimate the time for a sub-lease tenant to enter into an agreement and complete any improvements.

The Company continued its reduction-in-force actions begun in the fourth quarter of fiscal 2019 and recorded additional severance and benefits charges of $2.2 million during the period.

Cash payments of $3.6 million were paid during the three months ended September 30, 2019. Certain amounts have been reclassified from restructuring liabilities and have been recorded as a reduction to operating lease ROU assets as of July 1, 2019.
