The preamble informs the world that you were not merely hired but nurtured. Call it what you will . . . Generally, the first enumerated paragraph after the preamble gets right to the point. It's downhill from there. Note that there are two distinct concepts at play.
Information covers the disclosures contained in the records.
So, the BD considers the records and information contained therein to be its property. Frequently, no allowance is made for accounts you brought with you or for accounts whose leads you independently generated. And if that's not clear enough, you are often asked to agree not to divulge or disclose the information to any third party, especially a competitor of the BD, either during your tenure or thereafter. Finally, the agreement will recount the expense of time, effort, and money necessary to develop and acquire the records and information and you will agree not to duplicate the records and information and will reaffirm that they are the BD's property and constitute trade secrets. According to some laws and courts, if the records or data an RR is using is generally available, for example, listings in the yellow pages or a trade directory, then the BD may not be legally entitled to claim an exclusive property right.
