The mark consists of an outline of a broken shield, wherein the uppermost arch is defined by curved left and right line segments that mutually frame a graphically stylized bird. A combination of two parallel chevrons is centered and superimposed over a compass arrow, which depicts the bird's respective wings and body. The winged parallel chevrons define a negative space that extends through the compass arrow body. The broken shield is further composed of left and right vertical line segments that intersect with the uppermost arch and the curved line segments forming the mark's tapered end-point. The stylized acronym "WISL" is featured in capitalized letters and centered within the borders of the shield, wherein each letter features negative space that forms an overall watermark design.
