<p class="MsoNormal">Edgar is going to be out of the office for a bit. I will be handling this issue for you in his absence. He has an inquiry filed with the product group. I just pinged them to let them know that I’m their new contact. As soon as I have
more information, I’ll let you know.<o:p></o:p></p>
