Option to acquire noncontrolling interests

Assets and Liabilities Measured at Fair Value on Recurring Basis

Schedule of changes in the estimated fair value using significant unobservable inputs (Level 3)

During the year ended January 31, 2017, we acquired two majority owned subsidiaries for which we hold an option to acquire the noncontrolling interests. We account for the option as an in-substance investment in the noncontrolling common stock of each such subsidiary. We include the fair value of the option within other liabilities and do not recognize noncontrolling interests in these subsidiaries. The following table presents the change in the estimated fair value of this liability, which is measured using Level 3 inputs, for the years ended January 31, 2019 and 2018:

	Year Ended January 31,
