Total net property, plant & equipment   $ 65,020     $ 66,370  

 

Depreciation on the components of property, plant and equipment is calculated using the straight-line method to allocate their depreciable amounts over their estimated useful lives as follows:

 

     Years  
 Plant and Buildings     20-30  
 Machinery & Equipment     5-7  
 Furniture & Fixtures     3-5  

 

For the three months ended June 30, 2017 and 2016, the Company recorded depreciation expense of $1.2 million for each period. For the six months ended June 30, 2017 and 2016, the Company recorded depreciation expense of $2.3 million and $2.4 million respectively.

 

Management is required to evaluate these long-lived assets for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. Management determined there was no impairment on the long-lived assets during the three and six months ended June 30, 2017 and 2016.
