Material changes and management commentary
- Revenue growth reflected stronger unit sales in industrial, consumer and computer markets, including appliances, industrial controls, LED lighting, motor drives, renewable-energy systems and desktop PCs. Industrial revenue mix rose to 34% from 28%; communications fell to 21% from 24%.
- Gross-margin improvement was attributed to cost reductions, higher production volumes, a weaker Japanese yen against the U.S. dollar and a more favorable end-market mix.
- R&D expense rose to $51.7 million from $45.7 million, primarily reflecting Concept-related headcount and expanded product development. Sales and marketing expense rose to $45.5 million from $38.0 million, also reflecting Concept and sales-force expansion.
- International sales were 95% of revenue; distributors accounted for 75% of net product sales. The top ten customers represented 59% of revenue, with Avnet at 19%.
- Management provided no quantified revenue or earnings guidance in the supplied filing text. It expects international sales to remain a substantial share of revenue and stated that liquidity is expected to cover requirements for at least the next 12 months.
Risks, contingencies and unusual items
- SemiSouth: 2012 charges totaled approximately $58.9 million across operating and other expense, including write-offs of investments, loans, a prepaid royalty and a guarantee-related obligation. No comparable charge was recorded in 2013.
- Taxes: The company settled the IRS examination of 2003–2006 returns in 2012, paying approximately $42.4 million in taxes and interest (elsewhere the filing reports $42.6 million). The IRS audit of 2007–2009 returns remained ongoing at year-end 2013; unrecognized tax benefits were $12.7 million. The 2013 income-tax benefit was $1.8 million, producing a negative 3.3% effective tax rate, influenced by geographic earnings mix and tax credits.
- Intellectual-property litigation: Multiple patent disputes remained unresolved, including Fairchild matters and appeals in China. The company could not estimate a loss or range of loss; adverse outcomes could entail damages, injunctions, licensing costs or restrictions on products. Legal costs have been material.
- Other claim: Trinity Capital alleged a $2.4 million liability under a SemiSouth lease guarantee; Power Integrations denied the allegations and said it would contest the suit.
- Operating risks: No long-term customer contracts, cancellable or reschedulable orders, customer and distributor concentration, price competition, demand cyclicality, and reliance on third-party wafer foundries and assembly providers. The company estimated qualifying an alternate wafer source could take 12–24 months.
- Currency exposure: A 10% U.S. dollar change against the yen was estimated to affect gross margin by approximately 0.8–1.0 percentage points, all else equal.
Management reported effective disclosure controls and internal control over financial reporting as of year-end; the auditor issued an unqualified opinion on the financial statements and internal controls.
Important facts for investors to verify
- How much of reported growth reflects underlying volume and demand versus the full-year inclusion of Concept, and whether improved margins are sustainable.
- Distributor inventory, sell-through and price-adjustment exposure: deferred distributor revenue was $25.5 million at year-end, versus $20.7 million a year earlier.
- Progress and potential financial exposure from patent litigation, the Trinity claim and the ongoing IRS audit.
- Cash availability and tax consequences associated with approximately $105 million of foreign earnings designated as indefinitely reinvested outside the U.S.
- Wafer supply capacity and renewal/transition risk, including the Renesas agreement expiring in December 2014.
- Reconcile the filing’s differing stated totals for the 2012 IRS settlement payment ($42.4 million versus $42.6 million) when reviewing detailed tax disclosures.
