Maintenance and repairs are expensed as incurred, and costs of<div style="display: inline; font-family: Times New Roman, Times, serif; font-size: 10pt;"> new equipment and buildings, as well as costs of expansions or refurbishment of existing equipment and buildings, including interest where applicable, are capitalized. Depreciation and amortization are determined by the units of production method for most equipment and by the straight-line method for the remaining assets based on the estimated useful lives of the related assets. Estimated useful lives by major classes of property and equipment are as follows: Land improvements (<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">15</div> – <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">30</div> years); Buildings (<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">20</div> – <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">40</div> years); and Machinery and equipment (<div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">3</div> – <div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">30</div> years). Depreciation expense calculated under the units of production method <div style="display: inline; font-style: italic; font-style: normal; font-weight: inherit;"> may </div>be less than, equal to, or greater than depreciation expense calculated under the straight-line method due to variances in production levels. Upon disposal, costs and related accumulated depreciation of the assets are removed from the accounts and resulting gains or losses are reflected in operating expenses. The Company leases certain equipment under long-term capital leases, which are being amortized on a straight-line basis over the shorter of its useful life or the lease term.</div></div> <div style=" font-family: Times New Roman, Times, serif; font-size: 10pt; margin-top: 0pt; margin-bottom: 0pt;"> </div> <div style=" margin: 0pt; text-align: justify; text-indent: 27.35pt; font-family: Times New Roman, Times, serif; font-size: 10pt;">The Company assesses impairment of <div style="display: inline; font-family: Times New Roman, Times, serif; font-size: 10pt;">property and equipment whenever changes in circumstances indicate that the carrying values of the asset or asset group(s) <div style="display: inline; font-style: italic; font-style: normal; font-weight: inherit;"> may </div><div style="display: inline; font-style: italic; font-weight: inherit; font-style: normal;">not</div> be recoverable. The asset group is the lowest level at which identifiable cash flows are largely independent of the cash flows of other groups of assets or liabilities. The recoverable value of a long-lived asset group is determined by estimating future undiscounted cash flows using assumptions about the expected future operating performance of the Company.</div></div></div></div></div></div>
