I've called this meeting because, as you're all probably aware, we have some security issues in this building. There have been a number of thefts and repots of unauthorized persons wandering around the premises. So, we have some new guidelines to deal with this Some of these are just common sense; so, to begin with, can I ask you all to close any windows before you leave the building at night? From next month, all the office space will be air-conditioned and the windows will be sealed，so this will cease to be a problem Next, the new I.D. swipe-card system will be in place from Monday, so if you haven't collected your card from Jenny, please do so before you go.
