The logo shows the letters "UL" inside a ring, all dark red on white. The typeface use is slender and thick, sans serif and of constant width; the width of the ring matches that of the letters; the letter "U" is placed higher than the "L". The flag seems to be 3:5 and the gap between the outer edge of the disc and the horizontal edges of the flag seems to be the same as its width.
