Litigation

The Company may be a party to routine claims or litigation incidental to its business. The Company does not believe that it is a party to any pending legal proceeding that is likely to have a material adverse effect on its business, financial condition or results of operations or cash flows.

In connection with a credit facility amendment executed with PacWest on August 9, 2017, the Company agreed to issue the bank warrants to acquire Membership Units. In 2018, the Company and the bank agreed that 3,388 warrants would be issued at a strike price of $35.42 per unit, which was subsequently reflected in the Company’s books and records. Following the Company’s announcement of the Master Transactions Agreement (“MTA”), on February 3, 2021, PacWest issued a letter to the Company demanding 52,632 warrants in satisfaction of the provisions contained

in the August 9, 2017 credit facility amendment. On June 8, 2021, the Company and PacWest entered into a settlement agreement and mutual release where both parties acknowledged and agreed that the original 3,388 warrants issued were in full compliance of the credit facility amendment.

Lease Commitments

The Company’s lease arrangements consist primarily of corporate and manufacturing facility agreements. The leases expire at various dates through 2028, some of which include options to extend the lease term. The options with the longest potential total lease term consist of options for extension of up to five years following expiration of the original lease term. All of the leases are operating leases. The Company is headquartered in Aliso Viejo, California and has various research and design centers, sales support offices, and manufacturing facilities throughout the world. The key lease terms for the principal locations are summarized below:

In July 2015, the Company entered into a five-year operating lease for its 14,881 square foot headquarters in Aliso Viejo, California, which is payable monthly with periodic rent adjustments over the lease term. The lease requires a security deposit of $30, which is recorded in other assets on the Company’s consolidated balance sheets as well as a tiered, time-based letter of credit that has now reached its lowest tier of $200. Subsequently, the rentable area was expanded to 18,000 square feet and the lease was extended through the end of June 2023. Rent expense is approximately $38 per month.

Separately, effective January 2020, the Company entered into a lease for a property in Scotland. The lease agreement has a term through June 2024 and monthly rent of approximately $16 per month.

In October 2017, the Company entered into a 26-month operating lease for its Wuxi sales and design center. Rent for the associated office is payable monthly with periodic rent adjustments over the lease term. The lease was subsequently extended through December 2022. Rent expense is approximately $8 per month.

In May 2021, the Company entered into a seven-year operating lease for a location in Detroit, Michigan, which is payable monthly with periodic rent adjustments over the lease term. The lease will expire in 2028 with an initial monthly rent of approximately $22 per month.

Rent for the associated office is payable at approximately $38 per month. The lease will expire on May 31, 2028. Rent for the associate warehouse is at approximately $3 per month. This lease will expire on November 30, 2023.

The total monthly rent for the remainder locations of the Company around the world is not material.
