was valued at over $90 billion. At the same period, it was also recognized as the most cash-rich Japanese company, with its net cash reserves of ¥1.8 trillion. The company was immensely profitable throughout the 1990s and early 2000s in part because of the success of its new PlayStation line. The company encountered financial difficulty in the mid- to late-2000s due to a number of factors: the global financial crisis, increased competition for PlayStation, and the devastating Japanese earthquake of 2011. The company faced three consecutive years of losses leading up to 2011. While noting the negative effects of intervening circumstances such as natural disasters and fluctuating currency exchange rates, the Financial Times criticized the company for its "lack of resilience" and "inability to gauge the economy," voicing skepticism about Sony's revitalization efforts, given a lack of tangible results. In September 2000 Sony had a market capitalization of $100 billion; but by December 2011 it had plunged to $18 billion, reflecting falling prospects for Sony but also reflecting grossly inflated share prices of the 'dot-com bubble' years. Net worth, as measured by stockholder equity, has steadily grown from $17.9 billion in March 2002 to $35.6 billion through December 2011. Earnings yield (inverse of the price to earnings ratio) has never been more than 5% and usually much less; thus Sony has always traded in over-priced ranges with the exception of the 2009 market bottom. On 9 December 2008, Sony announced that it would be cutting 8,000 jobs, dropping 8,000 contractors and reducing its global manufacturing sites by 10% to save $1.1 billion per year. In April 2012, Sony announced that it would reduce its workforce by 10,000 (6% of its employee base) as part of CEO Kaz Hirai's effort to get the company back into the black. This came after a loss of 520 billion yen (roughly US$6.36 billion) for fiscal 2012, the worst since the company was founded. Accumulation loss for the past four years was 919.32 billion-yen. Sony planned to increase its marketing expenses by 30% in 2012. 1,000 of the jobs cut come from the company's mobile phone unit's workforce. 700 jobs will be cut in the 2012–2013 fiscal year and the remaining 300 in the following fiscal year. Sony had revenues of ¥6.493 trillion in 2012 and maintained large reserves of cash, with ¥895 billion on hand as of 2012. In May 2012, Sony's market capitalization
