(6) | Fair Value Measurements
The accounting guidance for using fair value to measure certain assets and liabilities establishes a three tier value hierarchy, which prioritizes the inputs to valuation techniques used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets for identical assets or liabilities; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little, if any, market data exists, therefore requiring an entity to develop its own assumptions about the assumptions that market participants would use in pricing the asset or liability. Cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities have carrying values that approximate fair value due to the short-term maturity of these financial instruments. The fair value of the Company’s debt instruments is described in Note 7, Long-Term Debt. Certain assets are measured at fair value on a nonrecurring basis. These assets are adjusted to fair value when there is evidence of impairment. During the 2018 fourth quarter, the Company reduced certain vessels to fair value due to its decision in 2018 to retire certain older vessels requiring expensive BWMS equipment at their next scheduled drydock and put a certain older barge up for sale in its marine transportation segment. The fair value of these vessels was $13,467,000 at December 31, 2018 and $13,247,000 is presented in marine transportation equipment and $220,000 is presented in prepaid expenses and other current assets.
