Material Changes vs. Prior Period
- Revenue Growth: Driven by a 108.9% increase in aluminum-case cell sales (OEM market) and the introduction of high-power lithium-phosphate cells ($18.5 million revenue) and lithium polymer cells ($1.0 million revenue).
- Margin Expansion: Gross margin improved to 27.6% due to economies of scale reducing unit manufacturing costs, which offset market-driven price declines.
- Expense Increases: Operating expenses rose to $17.1 million (from $10.4 million), largely due to the adoption of SFAS 123R (share-based compensation expense of $4.3 million) and increased professional fees related to financial restatements.
- Liquidity Pressure: Short-term bank loans increased by $28.4 million to fund working capital and capital expenditures. Working capital surplus decreased significantly from $21.0 million to $4.6 million.
Guidance, Risks, and Unusual Items
Internal Control Material Weaknesses
Management and the independent auditor (KPMG) concluded that the company did not maintain effective internal control over financial reporting as of September 30, 2006. Seven material weaknesses were identified, leading to three restatements of prior financial statements. Key weaknesses included:
- Insufficient personnel with U.S. GAAP expertise.
- Errors in capitalization of interest costs and depreciation.
- Incorrect accounting for deferred taxes and share-based compensation.
- Errors in earnings per share calculations.
Legal Proceedings
The company is a defendant in a patent infringement lawsuit filed by Hydro-Quebec and the University of Texas System regarding high-power lithium cells manufactured for A123 Systems (used in Black & Decker power tools). An adverse ruling could result in damages, injunctions, or royalty payments, materially affecting the power tool business segment.
Property and Regulatory Risks
The company does not hold the land use right certificate for its BAK Industrial Park facilities. While negotiating with the Shenzhen municipal government, failure to secure these rights could result in fines, forced vacating of facilities, or inability to insure the assets.
Customer Concentration
The top five customers accounted for 42.3% of total revenue in 2006. A123 Systems alone represented 12.9% of revenue.
Investor Verification Checklist
- Internal Control Remediation: Verify the progress of hiring U.S. GAAP-trained personnel and implementing new accounting procedures to address the seven material weaknesses.
- Land Use Rights: Confirm the status of negotiations with the Shenzhen government regarding the land use certificate for the BAK Industrial Park.
- Patent Litigation: Monitor the status of the Hydro-Quebec/University of Texas patent infringement suit and its potential impact on the A123 Systems contract.
- Debt Covenants: Review compliance with financial covenants (e.g., current ratio, monthly revenue decline limits) given the high level of short-term debt ($67.9 million).
- Cash Flow Management: Assess the company's ability to convert inventory and receivables into cash to service debt, given the negative operating cash flow in 2006.
