The mark consists of two separate lines, the first of which is comprised, starting at the lower left of the mark, of a serif connected to a vertical stem above said serif, which connects to a second serif at the upper-left apex of the mark, from which point the line continues on a 45-degree angle to the lower right as a straight stroke, continuing then as a curved stroke to the left and ending at a point slightly higher than the beginning lower-left serif, and the second of which is a vertically mirrored copy of the first line (except for a lack of a second serif) positioned so that each 45-degree stroke runs parallel to the other and the second serif of the first line is on the same y-axis point as the only serif of the second line, such that the effect of the two lines is to resemble a letter "S" contained within a wider letter "N".
