Our acquired intangible assets are amortized using the straight-line method over their estimated useful lives of seven to fifteen years. The following table shows the cost, accumulated amortization and weighted average useful life in years for our acquired intangible assets as of June 30, 2026 (in thousands).

(1) A partner is currently evaluating the potential return of a target. Through discussions with the partner, the deadline for making a decision has been extended and we now expect the partner will make a decision by February 2027. If the partner does decide to return the target in the future without nominating an alternative target with similar future cash flows, we would be required to evaluate the impact to our acquired customer relationship intangibles associated with the Elektrofi acquisition, along with other identified intangibles and goodwill of the reporting unit. Such assessment could result in a material interim impairment charge to intangibles and/or goodwill, depending on the facts and circumstances.
