With that out of the way, I'd like to turn the call over to our Chief Executive Officer and President, Morten Arntzen. Morten?
Morten ArntzenThanks, Jim. Good morning, everyone, and thank you for joining us on our second quarter call. With me in New York are Myles Itkin, our CFO; Lois Zabrocky, Chief Commercial Officer for all International Flag businesses; Janice Smith, our Chief Risk Officer; Jim Edelson, General Counsel; Jerry Miller, our Controller; and John Collins, Head of Investor Relations. Joining us from Newcastle is Captain Ian Blackley, Head of our International Flag Shipping Operations; and from Tampa, Captain Bob Johnston, led the U.S. Flag Unit. Please turn to Page 3 of presentation. When we spoke last May -- back in May, activity in our international flag markets was relatively healthy, especially in the larger crude classes and for MRs. Not long thereafter, demand's fell off in these segments as seasonal and technical factors reversed. Spot rates fell throughout May and then spent June at levels well below when the quarter opened, and that levels in some trade lanes close to operating cost breakeven levels.
