Other Obligations

We have an outstanding installment obligation of $2,103 related to the fiscal 2012 intra-entity transfer of the intellectual property of our subsidiary Webs, Inc., which results in tax being paid over a 7.5 year term and has been classified as a deferred tax liability in our consolidated balance sheet as of June 30, 2018.

Legal Proceedings

We are not currently party to any material legal proceedings. Although we cannot predict with certainty the results of litigation and claims to which we may be subject from time to time, we do not expect the resolution of any of our current matters to have a material adverse impact on our consolidated results of operations, cash flows or financial position. In all cases, at each reporting period, we evaluate whether or not a potential loss amount or a potential range of loss is probable and reasonably estimable under the provisions of the authoritative guidance that addresses accounting for contingencies. We expense the costs relating to our legal proceedings as those costs are incurred.
