PwC in court over Colonial Bank audit; BHP, Lenovo, Cisco and Santander UK also in the news A round up of some of the week’s most significant corporate events and news stories. US court told PwC cut corners in Colonial audit Control+C, Control+V. The keyboard shortcuts came into focus in a Miami court this week, as PwC stood accused of cutting corners in its audit of Colonial Bank, once the seventh largest in the US. There were billions of dollars of losses for the Federal Deposit Insurance Corporation when Colonial went bust in 2009. PwC had signed off on six years of financial statements from Alabama-based Colonial, which was brought down by its close relationship with Taylor, Bean & Whitaker, a defunct mortgage underwriter. TBW left big holes in Colonial’s accounts by running up huge loans secured against assets that did not exist. The plaintiffs, acting on behalf of TBW’s bankruptcy trustee, are seeking $5.5bn plus punitive damages, in the biggest ever trial of an audit firm. They claim that PwC was in a position to catch and stop the fraud but missed multiple red flags; PwC has countered that no auditor can reasonably be expected to catch a well-organised and determined fraud. In court this week a jury was shown a 2006 document in which a PwC representative — an intern — assigned to identify assets pledged as collateral reported back that she “felt” the collateral was “adequate.” The same report the following year, signed off by more senior staff, contained the same paragraph. “It’s crazy,” said Steven Thomas, lead trial lawyer. “Saying they “feel” the collateral was adequate really meant they had a belief that was true. But they just copied and pasted what an intern wrote from the prior year.” The trial is expected to run for another three or four weeks. But even if the case gets bogged down in years of appeal and settlement talks, it could have big implications for the way audit firms carry out their assignments. Mr Thomas noted that the Public Company Accounting Oversight Board, the watchdog for the industry in the US, is keeping a close eye on the outcome. “If we can keep pushing the issue, we think it’ll make a difference in the US and elsewhere,” he said. Cisco problems run deep as it seeks to change direction The problems are not always in the numbers. Cisco might have beaten earnings expectations and met analysts’ estimates on revenue in the fourth quarter when it reported on Wednesday — but it was clear from its earnings call that the network equipment maker is living in troubled times, writes Hannah Kuchler in San Francisco. ©Reuters The Silicon Valley company is experiencing a structural shift to “software-defined networking” that has allowed more competitors into its market and pushed it to seek profits in new areas, from cyber security to data analytics. To do this, it announced plans to cut 5,500 jobs, a full 7 per cent of its global workforce, from its slower growing business and to plough the savings into new investments and acquisitions. Cisco has also warned of a “challenging macro environment”, with some customers delaying major purchases. Chuck Robbins, Cisco chief executive, said the EU referendum had “real impact” in the UK and he called for clarity on how the Brexit process would actually work. Finally, Cisco has to be wary about the leak from Shadow Brokers, a hacker group that claims to have obtained internal tools used by the US National Security Agency, one of which was a flaw in a Cisco product deployed in companies worldwide. After the Edward Snowden leaks in 2013, then Cisco chief executive John Chambers came out fighting, asking President Barack Obama to stop the NSA from hacking into his equipment. So far, after this leak, Cisco has fixed the flaw but not yet made a stand. Worst year for BHP Billiton after Samarco dam collapse BHP Billiton reported its worst ever annual loss after a year of financial turmoil and a mine accident in Brazil that killed 19 people, writes Pilita Clark in London. The Anglo Australian group recorded a net loss of $6.4bn after more than $7bn of impairment charges, some related to the November dam collapse at Samarco, an iron ore miner BHP owns jointly with Brazil’s Vale. ©AFP A Brazilian dam burst and a slide in commodity prices have led to an 81% year on year contraction in BHP Billiton’s profit Andrew Mackenzie, chief executive of the world’s most valuable mining company, acknowledged that he and the group were still coming to terms with the accident, which had led to “huge suffering”. The company also recorded $4.9bn of writedowns, after tax, on its US shale investments, part of an oil business it started developing before crude prices began to plummet in 2014. The company, like other miners, was broadly hit by sliding commodity prices, especially in the last months of 2015. It said it would pay a final dividend of 14 cents per share, making an annual dividend of 30 cents, down 75 per cent compared with the previous year. Average prices for its output during the year fell between 17 per cent for coal and 43 per cent for oil, compared with the previous 12 months. Mr Mackenzie said he expected commodity prices to remain “low and volatile” in the short and medium term but they were no longer in “free fall”. He suggested BHP could generate more cash this year after productivity gains and cost cuts. The underlying performance was “strong and getting stronger”, he said. ● Related Lombard note: BHP’s mini-Macondo disaster Lenovo hopes smartphone push will offset PC decline A decade after Lenovo bought IBM’s personal computer business, propelling itself to the top ranks of the global PC industry, it is hoping to do the same in the smartphone sector, writes Tom Mitchell in Beijing. ©Getty It is a critical transition for the Chinese group, as PC sales stagnate and consumers turn to
