[1] Lease expense is included in cost of sales or SG&A expenses based on the nature of the leased item.  Short-term lease expense is excluded from this amount and is not material.  The Company also has certain variable leases which are not material.  The noncash component of lease expense for the first three months of 2021 and 2020 was $6.4 and $4.8, respectively, and is included in the Amortization caption in the condensed consolidated statement of cash flows.

[2] In March 2020, the Company approved a capital project to purchase additional machinery and equipment at one of its leased manufacturing facilities. This led to a lease modification to include a renewal option that would extend the lease for an additional five years through 2029.  The modification resulted in an increase to the Company’s right of use assets and corresponding lease liabilities of approximately $7.3 recorded in the first quarter of 2020.
