Goodwill and Intangible Assets
(a) Goodwill
For the fiscal year ended September 30, 2025, we recorded a non-cash out-of-period adjustment resulting in an increase of $3.8 million to deferred tax assets to correct an error related to a prior period, with an offset to goodwill shown as an adjustment. See Note 16 – Income Taxes for additional details.
The changes in the carrying amount of goodwill for the fiscal years ended September 30, 2025 and 2024 were as follows (dollars in thousands):

About Goodwill & Intangibles Disclosures

Goodwill and intangible asset disclosures reveal the premium paid in acquisitions and how management assesses whether that premium retains its value. Since goodwill is no longer amortized under US GAAP, the annual impairment test is the only mechanism that adjusts carrying values downward — making the assumptions behind that test critically important for investors.

Key signals: a history of goodwill impairments suggests management consistently overpays for acquisitions. Watch the gap between reporting unit fair value and carrying amount — when fair value exceeds carrying amount by less than 10-20%, a small decline in business performance could trigger a write-down. For finite-lived intangibles, examine useful life assumptions across customer relationships, technology, and trade names; aggressive estimates inflate near-term earnings. Compare total intangibles-to-total-assets ratios against peers to assess acquisition dependency. Rising goodwill as a percentage of equity can signal balance sheet fragility.
