 You mentioned just a minute ago about the you recommend that people and they lose their passports that they don't try to reuse them. Can you quantify what percentage of those last because I was I read in the press today that many of the still last passports get reused by people who try to reuse them. Is that what percentage of that is that among the total database? I can tell you that our experience is that most of the passports that are used by people after they've been reported stolen are used by the true passport holder. Now since there are 42 million passports in our database even if you say it's half or more than half or two-thirds that still leaves so many travelers who could cause us harm and the story I go back to is is the World Trade Center bombing number one in 1993 one person entered the US with the stolen passport and he mastermind the first attack on the World Trade Center and if you think of the September 11th bombings 19 people so for our perspective it's common sense prudent good due diligence to make sure that you don't let anyone you don't know or carrying a passport that's lost or stolen cross your border and your country or border plane.
