The mark consists of a discontinuous quadrilateral having four equal sides, wherein the upper-left and lower-right hand corners of the mark feature two right angles, and wherein the lower-left and upper-right hand corners of the mark are each indicated by negative diagonal spaces defined by perpendicular line segments having tapered endpoints. The acronym "NISA" is rendered in capitalized letters and enclosed within the discontinuous quadrilateral, wherein the letter "I" is stylized in an elongated font having a sharply angled vertex that projects above the letters "N," "S," and "A" of the "NISA" acronym. The angled vertex of the letter "I" is replicated in the angled negative space that divides the uppermost side of the discontinuous quadrilateral. The word "NATION" is depicted in capitalized letters in a reduced font size and located over the letters "S" and "A" of the "NISA" acronym. Four five-pointed stars are centered below the "NISA" acronym, wherein two smaller stars are located slightly above and mutually flank a pair of larger stars.
