Accounting Policies [Abstract]
Leases	Leases We have operating leases primarily consisting of offices and lab space, machinery and equipment and vehicles. We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right of use (“ROU”) assets, other current liabilities and long-term operating lease liabilities in our Consolidated Balance Sheet. Finance leases are included in property and equipment, other current liabilities and other long term liabilities in our Consolidated Balance Sheet. Lease assets and lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. Where our lease does not provide an implicit rate, we estimate the discount rate used to discount the future minimum lease payments using our incremental borrowing rate and other information available at the commencement date. The ROU assets also include all initial direct costs incurred. Our lease term may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option.
