The mark consists of a hollow circle with 4 point stars at bottom left and top right corners. The width of the circle drops to nothing on either side of the stars, leaving just the stars to virtually connect the two sides of the circle. Top left and bottom right corners of the circle have mirror image 'S' shaped offshoots aligned such that a middle 'S' shape is created in the negative space.
Color is not claimed as a feature of the mark.
