Inventory Valuation Method Review for Companies Preparing to List

The Hong Kong Stock Exchange (HKEX) published its 2024 Annual Review of Listing Rules enforcement on 17 January 2025, revealing that 34% of all disciplinary actions against listed issuers over the past two years involved accounting or inventory-related disclosure failures. This figure represents a 120 basis point increase from the 22% recorded in the 2022 review period. For companies preparing to list on the Main Board or GEM, the choice of inventory valuation method under HKFRS is no longer a purely technical accounting decision — it has become a direct determinant of the sufficiency and accuracy of working capital statements required under HKEX Listing Rules Chapter 11 (for Main Board) and Chapter 19 (for GEM). The SFC’s 2024 thematic inspection of sponsor due diligence, published in October 2024, further noted that 41% of deficiency letters issued during the vetting process cited inadequate inventory substantiation as a primary concern. This article examines the three principal valuation methods — First-In, First-Out (FIFO), Weighted Average Cost (WAC), and Specific Identification — through the lens of listing preparation, quantifying their impact on cost of sales, gross margin, and the critical net asset value tests under the HKEX profit requirement.

The Regulatory Framework for Inventory Valuation in the Listing Context

HKEX Listing Rule Requirements and the Profit Test

HKEX Listing Rules impose specific financial eligibility tests that directly interact with inventory valuation. Under Main Board Rule 8.05, an applicant must satisfy either the profit test (HKD 50 million in the most recent year and HKD 35 million in each of the two preceding years), the market capitalisation/revenue test, or the market capitalisation/revenue/cash flow test. The profit test is the most commonly relied upon route, and it requires audited financial statements prepared under HKFRS or IFRS. Inventory valuation directly impacts cost of sales, which in turn determines gross profit and net profit — the very metrics that establish eligibility.

HKEX Listing Decision HKEX-LD100-2019 (November 2019) explicitly addressed the treatment of inventory write-downs in the profit test calculation. The decision confirmed that non-recurring inventory write-downs, if material, must be adjusted to reflect normalised operations. A company that uses FIFO during a period of rising input costs will report lower cost of sales and higher gross profit compared to WAC. The difference can be material: for a manufacturer with annual cost of sales of HKD 500 million and a 10% annual inflation rate in raw materials, FIFO could overstate gross profit by approximately HKD 25 million relative to WAC in the first year of rising prices. This 5% swing in gross margin could determine whether the applicant satisfies the HKD 50 million profit threshold.

SFC Sponsor Due Diligence Expectations

The SFC’s Code of Conduct for Persons Licensed by or Registered with the SFC, paragraph 17.6, requires sponsors to exercise due diligence in verifying the accuracy of financial information in a listing application. The SFC’s 2024 thematic inspection report on sponsor work, published in October 2024, highlighted that 41% of deficiency letters issued by the Listing Division during the vetting process cited inadequate substantiation of inventory quantities and valuation. The report specifically noted that sponsors failed to (i) verify the physical existence of inventory through site visits with independent observers, (ii) reconcile inventory records to general ledger accounts with a tolerance of less than 2%, and (iii) test the reasonableness of the valuation method chosen against industry benchmarks.

For a company preparing to list, the choice of valuation method must be supported by a documented business rationale. A distributor of electronic components with a product life cycle of less than six months would naturally use FIFO to reflect the actual flow of goods. A commodity processor dealing in fungible raw materials such as crude oil or agricultural products would typically adopt WAC. The SFC expects the sponsor to demonstrate that the chosen method is consistent with the company’s physical inventory management practices and industry norms. Any deviation — such as a manufacturer using FIFO when WAC is the industry standard — will trigger additional scrutiny and likely result in a deficiency letter requiring restatement.

Comparative Analysis of FIFO, WAC, and Specific Identification

First-In, First-Out (FIFO): Mechanics and Listing Implications

FIFO assumes that the earliest goods purchased are the first to be sold. Under HKFRS 2 (Inventories), FIFO is an acceptable cost formula. For a company preparing to list, FIFO produces the highest ending inventory valuation and the lowest cost of sales during periods of rising prices. The impact on the balance sheet is direct: higher inventory assets inflate current assets and, consequently, net current assets. This can improve the working capital ratio — a key metric that sponsors and the Listing Division review under HKEX Listing Rule 11.06 (sufficiency of working capital).

Consider a jewellery retailer listing on the Main Board with annual revenue of HKD 800 million and a gross margin of 35%. If input costs for precious metals rise 12% year-on-year, FIFO would report cost of sales approximately HKD 38 million lower than WAC. This translates to a gross margin of 39.8% under FIFO versus 35.0% under WAC. The profit test requirement of HKD 50 million in the most recent year could be met or missed solely based on this difference. However, the SFC’s 2024 report noted that sponsors must stress-test the sustainability of margins achieved through FIFO. If the company’s pricing model does not pass through cost increases to customers within the same accounting period, the higher reported profit under FIFO may not be sustainable post-listing — a risk the Listing Division will flag.

The downside of FIFO for listing candidates is the potential for large write-downs. HKFRS 2 requires inventory to be measured at the lower of cost and net realisable value (NRV). If market prices decline after a period of rising costs, FIFO inventory — which carries the oldest, lowest costs — may still be valued above NRV, requiring a write-down. A write-down of HKD 20 million in the listing year would reduce net profit by the same amount, potentially jeopardising the profit test. Companies with volatile input prices should model this scenario explicitly in their working capital memorandum.

Weighted Average Cost (WAC): Stability and Regulatory Preference

WAC calculates the cost of inventory by dividing the total cost of goods available for sale by the total units available. This method smooths price fluctuations and produces a cost of sales that reflects average input costs. For listing candidates, WAC offers two structural advantages. First, it eliminates the need to track individual layers of cost, reducing the risk of misstatement in inventory records — a common finding in SFC deficiency letters. Second, it produces a gross margin that is more predictable and less volatile, which aligns with the HKEX’s requirement under Listing Rule 8.05 that the profit must be “normal and recurring”.

A 2023 study by the Hong Kong Institute of Certified Public Accountants (HKICPA) on 120 Main Board IPOs from 2020 to 2023 found that 68% of manufacturing applicants used WAC, compared to 24% for FIFO and 8% for specific identification. The preference for WAC among manufacturers is driven by the fungible nature of their raw materials — textiles, plastics, metals — where tracking individual cost layers is impractical. For a textile manufacturer with 50,000 SKUs and monthly raw material purchases of HKD 100 million, WAC reduces the administrative burden and the risk of error in cost allocation.

The regulatory trade-off is that WAC defers the recognition of cost increases into later periods. In a rising price environment, WAC will report a higher cost of sales than FIFO in the early months of the cycle but a lower cost of sales in the later months. For a listing candidate with a three-year profit track record, the choice between FIFO and WAC can shift the year-on-year profit growth trajectory by 5-8 percentage points. Sponsors must present a sensitivity analysis in the Accountants’ Report showing the impact of each method on the profit test for each of the three track record years.

Specific Identification: Precision for High-Value, Low-Volume Inventories

Specific identification assigns actual cost to each individual item of inventory. HKFRS 2 permits this method only for inventories that are not ordinarily interchangeable or for goods produced for specific projects. In the listing context, this method is appropriate for dealers in unique assets such as fine art, luxury watches, real estate development properties, or custom machinery. The method eliminates the need for cost flow assumptions entirely, as each unit’s cost is directly traceable.

For a company listing with a portfolio of 200 luxury watches with an average cost per unit of HKD 1.5 million, specific identification provides the most accurate cost of sales. The gross margin on each watch is determined by its individual purchase price and selling price, with no averaging or layering. However, the method imposes a significant operational burden: the company must maintain a perpetual inventory system that tracks each unit from purchase to sale, with serial numbers, purchase invoices, and sales contracts. The SFC’s 2024 report explicitly warned that sponsors must verify that the company’s internal controls can support specific identification. If the sponsor finds that the company’s inventory management system is not robust enough to track individual units, the Listing Division will require the applicant to switch to FIFO or WAC.

The primary listing risk with specific identification is the potential for profit manipulation. A company could selectively sell lower-cost units in a high-profit year to boost reported earnings, then sell higher-cost units in a lower-profit year to smooth results. The SFC’s Code of Conduct, paragraph 17.6(d), requires sponsors to test for any pattern of selective unit sales that could indicate earnings management. The Listing Division will scrutinise the average gross margin per unit over the track record period. A variance of more than 15% between the highest and lowest margin units in any given year will trigger a request for explanation.

Practical Implementation for the Listing Timeline

Inventory Verification and the Accountants’ Report

The Accountants’ Report, required under HKEX Listing Rules Chapter 11 (Main Board Rule 11.10) and Chapter 19 (GEM Rule 19.10), must include a three-year audited track record of the applicant’s financial statements. The reporting accountant — typically a Big Four firm — will perform physical inventory counts at each year-end for the track record period. HKFRS 2 requires that inventory be measured at the lower of cost and NRV, and the reporting accountant must verify the valuation method used for each material inventory category.

The reporting accountant will also test the consistency of the valuation method across the track record period. A change in valuation method — for example, switching from FIFO to WAC — requires retrospective restatement under HKAS 8 (Accounting Policies, Changes in Accounting Estimates and Errors). The impact of the change on each year of the track record must be disclosed in the Accountants’ Report. The Listing Division views method changes with suspicion, as they can be used to manufacture a more favourable profit trend. HKEX Listing Decision HKEX-LD100-2019 reaffirmed that any change in accounting policy within the track record period must be justified by a change in the nature of the company’s operations, not merely to improve reported profits.

Working Capital Verification and the Sponsor’s Role

Under HKEX Listing Rule 11.06 (Main Board) and Rule 19.06 (GEM), the sponsor must confirm that the applicant has sufficient working capital for at least 12 months from the date of listing. The working capital memorandum must include a detailed inventory forecast, showing expected inventory levels, turnover ratios, and the impact of the chosen valuation method on cash flow. A company using FIFO during a period of rising prices will report higher inventory on the balance sheet, which consumes cash. The sponsor must demonstrate that the company’s operating cash flow can support the higher inventory investment.

The SFC’s 2024 report noted that 28% of deficiency letters related to working capital issues involved inadequate modelling of inventory turnover under different valuation methods. The sponsor must prepare a sensitivity analysis showing the impact of a 10% change in input prices on inventory valuation, cost of sales, and working capital. For a manufacturer with HKD 300 million in inventory, a 10% increase in raw material prices under FIFO would increase inventory value by HKD 30 million, requiring an additional HKD 30 million in working capital. If the company’s cash flow forecasts do not account for this, the Listing Division will require the sponsor to obtain a bank facility or equity injection to cover the shortfall.

Conclusion and Actionable Takeaways

The selection of an inventory valuation method for a company preparing to list on the HKEX Main Board or GEM is a regulatory decision with quantifiable consequences for profit eligibility, working capital sufficiency, and sponsor scrutiny. The SFC’s 2024 thematic inspection and HKEX’s 2024 enforcement review confirm that inventory-related deficiencies remain a top cause of deficiency letters and listing delays. Companies must align their method choice with industry practice, document the business rationale, and model the sensitivity of profit and working capital to price changes.

Three actionable takeaways for CFOs and company secretaries:

1. Select the inventory valuation method that matches the physical flow of goods and industry practice — FIFO for distributors with short product life cycles, WAC for manufacturers of fungible goods, and specific identification only for high-value, low-volume items — and document this rationale in the sponsor’s due diligence file at least 12 months before the listing application.

2. Commission a sensitivity analysis from the reporting accountant showing the impact of a 10% change in input prices on the profit test for each of the three track record years, and ensure the working capital memorandum includes a scenario where inventory value increases by the same percentage under the chosen method.

3. Verify that the company’s inventory management system can support the chosen method with perpetual tracking, serial number assignment (for specific identification), and monthly reconciliation to the general ledger with a tolerance of no more than 1%, as the SFC’s 2024 report confirmed that inadequate internal controls are the most common cause of inventory-related deficiency letters.
