"hold water with the auditors" perhaps a better explanation is. Anavex stated $150M at Year End. Good enough for a 4 year run. 150 / 16 = 9.375M per quarter. This statement is end of first quarter Mar30th 2024. 150 - 9.375 = 140.625M left in the band and we actually have 139M so quarter #1 they didn't spend quite as much as expected.
