8.	Property and Equipment

The major classes of property and equipment are as follows:

	Useful Life	2015		2014
Production machinery and equipment	5 years	$	1,427,472	$	1,446,551
Other machinery and equipment, primarily computers and research equipment	3 – 5 years		421,318		602,974
Furniture and fixtures	7 years		648,131		670,567

Leasehold improvements*	Term of Lease		897,584		927,406
		$	3,871,035	$	4,124,028

We amortize leasehold improvements over the term of the lease, which in all cases is shorter than the estimated useful life of the asset.

Property and equipment includes $9,000 of equipment under capital leases with accumulated amortization of $7,000 and $5,000 at December 31, 2015 and 2014, respectively. During 2015, 2014 and 2013, we recorded $562,000, $488,000 and $400,000, respectively, of depreciation and amortization related to property and equipment.
