In April 2018, we received an offer and agreed to transfer our Australian exploration permit to a third party for consideration of approximately $0.2 million in cash and the release of approximately $1.3 million in liabilities incurred in connection with a canceled 2017 seismic survey. We will recognize a loss on the transfer of the permit of approximately $1.0 million during the second quarter of 2018. The transfer of our Australian exploration permit will allow us to further focus our upstream activities domestically.
