听力原文：Thank you all for attending today' s meeting. I appreciate the fact that you are very busy, so I understand the sacrifice you have made today to be here. The reason we asked you here today is to discuss an alarming rise in the incidence of office property theft. This may seem like a minor matter, but every year this problem costs the company more than a million dollars. Starting tomorrow, we are going to interview everyone in the company to find ways this problem can be solved. If you have any suggestions we would prefer it if you can raise them at your one-on-one meeting, and not at today' s meeting. Our security manager, John Bow, will be conducting the interviews and will contact you later in the day to schedule an interview. Thanks for your cooperation. What is the purpose of this talk?
