Gross goodwill is recorded cost before accumulated impairment; net goodwill is gross goodwill less accumulated impairment. Opening and closing net goodwill are the balances at the start and end of the reporting period. Historical impairment uses closing gross goodwill; acquisitions use closing net goodwill; current impairment and overall annual change use opening net goodwill.

The accumulated goodwill impairment / closing gross goodwill ratio divides accumulated goodwill impairment by matched closing gross goodwill. Both amounts must be strictly positive and relate to the same business scope. The ratio measures historical losses, including charges made before 2021, rather than current-year impairment expense or the proportion of companies recording a charge.

The four top-down graphs use accepted Group financial facts. Stocks include known closing balances, including extended-period year ends. Annual flow ratios/counts use comparable 12-month periods (350–380 days). Explicit positive additions or current goodwill charges identify events; absent or undisclosed fields are not zeros. A zero component requires affirmative evidence or a complete reconciled movement statement.

Discount rates and terminal-growth inputs are included only when they relate to eligible goodwill impairment tests. Reported ranges contribute one midpoint, and an explicit zero terminal-growth rate is retained. Headroom requires a positive matched surplus and the carrying amount of the whole CGU. Current write-down severity requires the goodwill balance immediately before the impairment test; this denominator was not established in the available evidence, so that measure is unavailable. Sensitivity scenarios and goodwill-only carrying amounts do not replace the required inputs.

Reported restatements are applied to the affected fields and identified with source reports and PDF pages; original facts remain in the supporting records. Q1 and Q3 use inclusive linear interpolation at (n−1)p. Restatement records

Group balance reconciliation

YHI’s 2021 closing Group net goodwill includes noncurrent goodwill (Note 20) and goodwill held for sale (Note 13). Gross cost and accumulated impairment are combined across the same two categories to match that perimeter.

This is an analyst reconstruction from disclosed balances, not a company-issued restatement.

Source figures and reporting unit

The amounts below are in S$ thousand and relate to the Group at 31 December 2021. PDF pages 121–122 correspond to printed pages 119–120; PDF page 103 corresponds to printed page 101.

Note 20 reports a transfer of 505 in gross goodwill cost and nil accumulated impairment. Note 13 reports closing held-for-sale net goodwill of 505. Together these support held-for-sale gross goodwill of 505 and accumulated impairment of zero.

Calculation and reconciliation

1. Combine gross cost across both categories: 1,934 + 505 = 2,439.
2. Combine accumulated goodwill impairment on the same perimeter: 770 + 0 = 770.
3. Net balance: 2,439 − 770 = 1,669, matching Group net goodwill of 1,164 + 505.
4. Accumulated-impairment ratio: 770 ÷ 2,439 × 100 = 31.57%. Both inputs are positive and use the same S$ thousand unit.

The 505 transfer is an internal balance-sheet reclassification, not an acquisition, impairment or economic disposal. It is included once in closing gross goodwill and is already included in Group net goodwill.

Effect on the analysis

The 2021 historical-impairment sample contains ten observations: mean 47.74%, median 40.06%, Q1 23.10% and Q3 73.60%.

The reconstruction establishes a historical balance ratio; it does not establish a 2021 impairment expense. YHI’s Group includes automotive and industrial activities. The 2021 coverage comprises ten qualifying pairs, 53 unmatched pairs, five zero or non-positive pairs, two scope exclusions and five companies without qualifying periods.

The historical monetary totals use the same 12 qualifying company-period observations as the 2025 accumulated goodwill impairment / closing gross goodwill mean and median. Each has positive, matched closing gross goodwill and accumulated goodwill impairment; zero and unmatched pairs are excluded. The totals therefore describe this selected positive-impairment sample rather than all 75 companies or the entire sector. Group goodwill can include other activities, monetary sums exclude verified consolidation overlaps; listed-company observations remain separate, and financial year ends differ. Accumulated goodwill impairment is the closing balance of historical write-downs rather than the expense for 2025.

Closing gross goodwill totals S$132.993227m and accumulated goodwill impairment totals S$33.847580m, shown as S$133 M and S$34 M after rounding the final sums. Each amount is converted as reported balance × reporting-unit multiplier × SGD per reporting-currency unit ÷ 1,000,000. SGD balances use a conversion factor of 1. For LY and Combine Will at 31 December 2025, the official currency-units-per-EUR rates are SGD 1.5105, MYR 4.7682 and HKD 9.1464. Duty Free’s 28 February 2025 balances use SGD 1.4037 and MYR 4.6459. SGD per foreign-currency unit is calculated by dividing the SGD/EUR rate by the foreign/EUR rate. Banque de France · 31 December 2025 · Banque de France · 28 February 2025.

Dividing the monetary totals gives 25.45%, which weights each balance by its closing gross goodwill. The 56.90% mean gives equal weight to each company’s ratio, while the 60.18% median is the middle value. All three measures use the same selected sample but describe it differently. Individual contributions and currency-conversion sources provide the detailed calculations.

Only monetary sums are adjusted. A sampled subsidiary’s additional contribution is removed when source disclosures confirm that a retained sampled parent fully consolidates it. Each balance is eliminated once through the hierarchy, without ownership weighting. Separately listed observations remain in all counts, participation rates, individual ratios and mean, median, Q1 and Q3.

Closing net goodwill uses its existing known-balance population. Gross goodwill and accumulated impairment retain each year’s original matched positive historical-impairment sample. Missing figures remain unknown; these disclosed sums are not complete sector totals. Aspial Lifestyle is outside that historical sample, so its elimination affects net monetary sums only.

Verified closing balances are included once in the calendar year of the actual period end, including 18-month reports. Closing monetary sums retain their existing disclosure populations and consolidation adjustments. Undivided extended-period movements are excluded from all annual acquisition, impairment and overall-change samples, including participation denominators. Original amounts below are in reporting units; unknown is not zero.

No separately supported 12-month component with matching balances was identified for these reports. No 12/18 scaling, duplication across years or carried-forward balances is used. Net Pacific’s auditor disclaims an opinion and its goodwill-note opening date is inconsistent with the reporting period; its disclosed closing balance is retained with that limitation.

Stacked counts partition known listed-company closing balances into zero and positive; missing balances are outside the stack. Monetary sums use fiscal-date SGD conversions and exclude verified duplicate subsidiary contributions. These are separate annual stocks; the original company observations remain in all counts and ratio statistics.
