On June 13, 2016, we received a debt covenant waiver as discussed in Note 7 - Debt.

In April 2016, the United States Internal Revenue Service (IRS) proposed certain significant adjustments to our research and development tax credit position as part of the 2011 to 2013 tax audit. Management disagrees with the proposed adjustments on technical and factual grounds. We plan to avail ourself of all administrative, and if necessary, judicial remedies and do not expect the adjustments to ultimately result in a material change to our financial position.
