The mark consists of a rectangle with two triangles, one contained within the other, extending upward from the top of the rectangle; and with two triangles, one contained within the other, extending downward from the bottom of the rectangle. Said rectangle contains five smaller rectangles within it. One of said rectangles contained within the outer, perimeter rectangle, contains six trapezoids conjoined into a single object, with each trapezoid sharing a side with at least one of the other trapezoids. The word "Northline" is set forth in the upper most of the interior rectangles. The term "Property Group" is set forth in the lowest of the interior rectangles. The text "Northline" is set forth with larger font size relative to the font size of "Property Group". The foregoing design elements appear in the color navy. The color white represents background, outlining, shading, and/or transparent area and is not part of the mark.
