The mark consists of Starting with a capital "B", consisting of a straight down stroke, then the first loop starting slightly above the down stroke, going right, then coming down and around to the left, but not touching the down stroke of the letter, then forming the second loop starting on the lower portion of the first, top loop, down and around to the left connecting with the down stroke of the letter; then a lower case u, lower case k, and a horizontal infinity symbol "∞" with a slight gap (not touching) the middle of the symbol representing "oo". (Further explanation of how to draw the infinity symbol would be: starting in the middle of the symbol, drawing a loop up and over, down to the left, circling back up to the right, looping back down, but not touching the middle of the loops.
