During the six months ended April 30, 2026, we recognized additions to goodwill of $30 million and reductions to intangibles of $3 million for measurement period adjustments to the estimated fair values of assets acquired and liabilities assumed from the 2025 acquisitions and other acquisition activity. See Note 2, “Acquisitions,” for additional information. During the six months ended April 30, 2026, we transferred $8 million from in-process R&D to developed technology as projects were successfully completed and recorded an impairment charge of $4 million related to the cancellation of an in-process R&D project.
During the six months ended April 30, 2026, foreign exchange translation had a favorable impact of $8 million on other intangible assets. Amortization of other intangible assets was $66 million and $131 million, respectively, for the three and six months ended April 30, 2026, compared to $32 million and $64 million, respectively, for the same periods last year.
Goodwill is assessed for impairment on a reporting unit basis at least annually in the fourth quarter of each year, or more frequently when events and circumstances occur indicating that the recorded goodwill may be impaired. The company has not identified any triggering events that indicate an impairment of goodwill for the six months ended April 30, 2026.
Estimated intangible assets amortization expense for each of the five succeeding fiscal years is as follows:
