Commitments and Contingencies Disclosure [Text Block] | 7 . Commitments and Contingencies From time to time, we are or may become subject to legal proceedings and claims that arise in the normal course of our business. In our opinion, the amount of ultimate liability, if any, with respect to known actions, will not materially affect our financial position. However, the outcome of any one or more matters cannot be predicted with certainty, and the unfavorable resolution of any matter could have a material adverse effect on us.
