Leases

12 Months Ended

Dec. 31, 2019

The Company leases certain office facilities, warehouses, manufacturing plants, equipment (which includes both office and plant equipment) and vehicles under operating leases. Leases with an initial term of 12 months or less are not recorded on the balance sheet; the Company recognizes lease expense for these leases on a straight-line basis over the lease term.

Certain leases include one or more options to renew. The exercise of lease renewal options is at the Company’s sole discretion. There are currently no renewal periods included in any of the leases’ respective lease terms as they are not reasonably certain of being exercised. The Company does not have any material purchase options.

Certain of our lease agreements have rental payments that are adjusted periodically for inflation or that are based on usage. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants.

In the second quarter of 2019, the Company began to evaluate strategic alternatives for one of its businesses in the HST segment. Prior to making a final decision on the options that were presented for this business, the business was informed in the

third quarter of 2019 of the loss of its largest customer. As a result, the Company accelerated its restructuring activities for this business and a decision was made to wind down the business over time. This event required an interim impairment test be performed on its long-lived assets, which resulted in an impairment charge of $0.6 million related to its building right-of-use asset. In the fourth quarter of 2019, the Company completed the consolidation of one of its facilities in the HST segment into the Optics Center of Excellence in Rochester, New York, which also resulted in an impairment charge of $0.4 million related to its building right-of-use asset. These charges were recorded as Restructuring expenses in the Consolidated Statements of Operations. See Note 14 for further discussion.

As part of the adoption of the new lease standard, the Company derecognized its liability for the construction of a new leased facility that was recorded in Other noncurrent liabilities on the Consolidated Balance Sheets and recorded it as a right of use asset in Other noncurrent assets on the Consolidated Balance Sheets with a corresponding lease liability in Accrued expenses and Other noncurrent liabilities on the Consolidated Balance Sheets.
