Mexico’s Investment Units (UDIS) are units based on price increases and are used to settle mortgage obligations or commercial acts. They were created in 1995 to protect banks and focused mainly on mortgage loans.

Banco de México publishes the value in pesos of the Mexico’s Investment Unit  for each day of the month in the Official Federal Gazette. On the 10th day of each month at the latest, Banco de México publishes the value of the Mexico’s Investment Unit corresponding to days 11 and 25 of the month, and on the 25th of each month at the latest it publishes the value corresponding to the 26th day of that month through to the 10th day of the following month.
