Legal Proceedings

The Company is party to various claims, legal proceedings and investigations arising in the ordinary course of business. Some of these actions involve complex factual and legal issues and are subject to uncertainties. At this time, the Company is not able to either predict the outcome of these legal proceedings or reasonably estimate a potential range of loss with respect to the proceedings. While it is not feasible to predict the outcome of such pending claims, proceedings and investigations with certainty, management is of the opinion that their ultimate resolution should not have a material adverse effect on results of operations, cash flows or financial position taken as a whole.

Beginning in 2005, the Company initiated claims in Iowa County Circuit Court against the City of Dodgeville (the "City") to recover overpaid taxes resulting from the City’s excessive property tax assessment of the Company’s headquarters campus for each tax year from 2005 through 2016. As of March 31, 2017, the City has refunded, as the result of various court decisions, over $6.5 million in excessive taxes and interest to the Company in the following amounts: (1) approximately $1.6 million arising from the 2005 and 2006 tax years that was recognized in Fiscal 2009; (2) approximately $1.6 million arising from the 2007, 2009 and 2010 tax years, recognized in Fiscal 2014; (3) approximately $0.9 million arising from the 2008 tax year, recognized in Fiscal 2015, and (4) approximately $2.4 million arising from the 2007, 2009, 2010, 2011 and 2012 tax years, recognized in Fiscal 2016.
