The S1 also detailed a direct share program for moderators, which was identified as a potential risk. Beyond the financial sector, S1 refers to the first sacral vertebra in human anatomy (forming the L5-S1 lumbosacral joint), a military staff designation for personnel and adjutants (BN S1), and the IFRS S1 international accounting standard for sustainability disclosures.

    S1, also called the sacral base, is the upper and wider end of the triangular-shaped sacrum. S1 consists of a body on the top with wing-shaped bones on either side, called the alae. At the back, the S1 vertebra contains a long bony prominence called the median ridge. There are bony openings (foramina) on the right and left sides of this ridge. L5 and S1 are joined by the lumbosacral facet joints lined with articular cartilage. [...] The L5-S1 motion segment provides a bony enclosure for the cauda equina (nerves that continue down from the spinal cord) and other delicate structures.
