When do you expect the dissolution process to be completed?
Upon approval of the Plan of Dissolution by our stockholders, we will work toward an orderly wind down of our business and operations. Subject to stockholder approval of the Plan of Dissolution, we currently expect to file a Certificate of dissolution as soon as reasonably practicable following stockholder approval of the Plan of Dissolution and expect to have the majority of our business operations completed by that time. Additionally, pursuant to the Delaware law, our corporate existence will continue for a period of at least three years, but we would not be permitted to carry on any business except that appropriate to wind up and liquidate our business and affairs.
