Contingent Liabilities [Abstract] |
Commitments and Contingencies Disclosure [Text Block] | Note 18 – Contingent Liabilities The Company is a defendant in lawsuits and other adversary proceedings arising in the ordinary course of business. Legal costs incurred in connection with the resolution of claims and lawsuits are generally expensed as incurred, and the Company establishes accruals for the outcome of litigation where losses are deemed probable and reasonably estimable. The Company’s assessment of the current exposure could change in the event of the discovery of additional facts with respect to legal matters pending against the Company or determinations by judges, juries, administrative agencies or other finders of fact that are not in accordance with the Company’s evaluation of claims. As of March 31, 2016, the Company had accrued charges of approximately $4.5 million for legal contingencies related to various proceedings. In certain cases, matters and proceedings, exposure to loss exists in excess of the accrual to the extent such loss is reasonably possible, but not probable. Management believes an estimate of the aggregate range of reasonably possible losses for current legal and other adversary proceedings is from $800,000 to approximately $10.6 million at March 31, 2016. Any estimate involves significant judgment, given the varying stages of the proceedings (including the fact that certain proceedings are currently in preliminary stages), the numerous unresolved issues in many of the proceedings, and the inherent uncertainty of the various potential outcomes of such proceedings. Actual liabilities may exceed the amounts accrued, and there can be no assurance that final resolution of these matters will not have a material adverse effect on the Company’s financial condition, results of operations or cash flows.
