NOTE C — GOODWILL AND OTHER INTANGIBLE ASSETS

Total accumulated goodwill impairment losses were $193.0 million at May 31, 2024. Of the accumulated balance, $141.4 million is included in our SPG segment, $14.9 million is included in our CPG segment, and $36.7 million is included in our PCG segment. There were no impairment losses recorded during fiscal 2024.

Changes in the Composition of our Segments in the First Quarter of Fiscal 2024

Effective June 1, 2023, certain Asia Pacific businesses and management structure, formerly of our CPG segment, were transferred to our PCG segment to create operating efficiencies and a more unified go-to-market strategy in Asia Pacific. As a result of this business realignment, $11.4 million of goodwill was reassigned from the CPG segment to the PCG segment using a relative fair value allocation approach.

USL Restructuring in the First Quarter of Fiscal 2024

Effective June 1, 2023, certain businesses of our USL reporting unit were transferred to our Fibergrate, Carboline and Stonhard reporting units within our PCG segment. As a result of this change, USL was no longer designated as a separate reporting unit and any remaining goodwill was transferred to the reporting units noted above. Additionally, during the three-month period ended August 31, 2023, we recognized a loss on sale of $4.5 million in connection with the divestiture of Universal Sealants' (USL) Bridgecare services division, which is a contracting business focused on the installation of joints and waterproofing in the U.K. The loss on this sale is included in SG&A in our Consolidated Statements of Income and net (gain) on sales of assets and businesses in our Consolidated Statements of Cash Flows.

Given these USL restructuring actions, we performed an interim impairment assessment of a remaining USL indefinite-lived tradename. Calculating the fair value of the tradename required the use of various estimates and assumptions. We estimated the fair value by applying a relief-from-royalty calculation, which included discounted future cash flows related to projected revenues impacted by this decision. In applying this methodology, we relied on a number of factors, including actual and forecasted revenues and market data. As the carrying amount of the tradename exceeded its fair value, an impairment loss of $3.3 million was recorded for the three months ended August 31, 2023. This impairment loss was classified as restructuring expense within our PCG segment.

USL Impairment Charges Recorded in the Third Quarter of Fiscal 2023

As part of our MAP 2025 operational improvement initiative and given the challenged macroeconomic environment, we evaluated certain business restructuring actions, specifically our go to market strategy for operating in Europe. During the third quarter ended February 28, 2023, due to declining profitability and regulatory headwinds, management decided to restructure the USL reporting unit within our PCG segment and correspondingly explored strategic alternatives for our USL infrastructure services business within the U.K., which represented approximately 30% of annual revenues of the reporting unit.

Due to this decision, we determined that an interim goodwill impairment assessment was required, as well as an impairment assessment for our other long-lived assets. Accordingly, we recorded an impairment loss totaling $36.7 million for the impairment of goodwill and $2.5 million for the impairment of an indefinite-lived tradename in our USL reporting unit during the third quarter of fiscal 2023. We did not record any impairments for our definite-lived long-lived assets as a result of this assessment.

Our goodwill impairment assessment included estimating the fair value of our USL reporting unit and comparing it with its carrying amount at February 28, 2023. Since the carrying amount of the USL reporting unit exceeded its fair value, we recognized an impairment loss. We estimated the fair value of the USL reporting unit using both the income and the market approaches. For the income approach, we estimated the fair value of our USL reporting unit by applying a discounted future cash flow calculation to USL’s projected EBITDA. In applying this methodology, we relied on a number of factors, including actual and forecasted operating results, future operating margins, and market data. The discounted cash flow used in the goodwill impairment test for USL assumed discrete period revenue

growth through fiscal 2027 for the ongoing USL businesses in the U.K. and North America as well as probability-weighted cash flows that were dependent on the methodology utilized in determining strategic alternatives for the U.K. infrastructure services business. In applying the market approach, we used market multiples derived from a set of companies similar to USL.

After recording the goodwill impairment charge of $36.7 million, $1.1 million of goodwill remained on the USL balance sheet as of May 31, 2023.

Calculating the fair value of the USL’s indefinite-lived tradenames required the use of various estimates and assumptions. We estimated the fair value of USL’s indefinite-lived tradenames by applying a relief-from-royalty calculation, which included discounted future cash flows related to projected revenues for those USL tradenames impacted by this decision. In applying this methodology, we relied on a number of factors, including actual and forecasted revenues and market data. As the carrying amount of one of the tradenames exceeded its fair value, an impairment loss of $2.5 million was recorded during fiscal 2023. This impairment loss was classified in restructuring expense within our PCG segment.

The impairment assessment for our long-lived assets, such as property and equipment and purchased intangibles subject to amortization, involved estimating the fair value of USL’s long-lived assets and comparing it with its carrying amount. Measuring a potential impairment of long-lived assets requires the use of various estimates and assumptions, including the determination of which cash flows are directly related to the assets being evaluated, the respective useful lives over which those cash flows will occur and potential residual values, if any. The results of our testing indicated that the carrying values of these assets were recoverable, as such we did not record an impairment of our long-lived assets during fiscal 2023.

The aggregate intangible asset amortization expense for the fiscal years ended May 31, 2024, 2023 and 2022 was $39.1 million, $43.5 million and $45.7 million, respectively. For the next five fiscal years, we estimate annual intangible asset amortization expense related to our existing intangible assets to approximate the following: fiscal 2025 — $43.3 million, fiscal 2026 — $30.3 million, fiscal 2027 — $28.7 million, fiscal 2028 — $26.3 million and fiscal 2029 — $25.1 million.
