Color is not claimed as a feature of the mark.
The mark consists of a Y-shape with the letters "A", "D" and "S" on each vertex of the shape. The letter "A" is on the top vertex, the letter "D" is on the left vertex, and the letter "S" is on the right vertex. The shape is enclosed by two semi-circles, one on the left and another on the right, that overlap to form a full circle. The semi-circle on the right-side of the shape is slightly smaller than the semicircle on the left.
