| Commitments And Contingencies                | Note 13 – Commitments and Contingencies 

 

The Company is routinely involved in various disputes, claims, lawsuits and other regulatory and legal matters, including both asserted and unasserted legal claims, in the ordinary course of business.  The status of each such matter, referred to herein as a loss contingency, is reviewed and assessed in accordance with applicable accounting rules regarding the nature of the matter, the likelihood that a loss will be incurred, and the amounts involved.  As of June 30, 2017, the aggregate amount of $15,259 is accrued for loss contingencies and is reported in the Company’s consolidated balance sheet as other accrued liabilities and other liabilities.  These accruals represent management’s best estimate of probable loss (as defined in the accounting guidance) for loss contingencies or the low end of a range of losses if no single probable loss can be estimated.  For some loss contingencies, the Company is unable to estimate the amount of the probable loss or range of probable losses.  While the final outcome of these loss contingencies cannot be predicted with certainty, and unfavorable outcomes could negatively impact the Company, at this time in the opinion of management, the final resolution of these matters are not expected to have a material adverse effect on the Company’s financial position, results of operations or cash flows.  Further, the Company has insurance coverage for certain of these loss contingencies, and as of June 30, 2017, estimates that approximately $3,407 of the amount accrued for these matters are probable of recovery through insurance, which amount is also reported in the Company’s consolidated balance sheet as deferred charges and other assets.

﻿

In addition to the aforementioned loss contingencies, the Company self-insures its employee medical benefit program, and maintains stop-loss coverage to limit the exposure arising from these claims.  The Company’s reserve for these claims totaled $1,770 at June 30, 2017 and represents a reserve for unpaid claim costs, including an estimate for the cost of incurred but not reported claims.
