Yokohama Rubber reports record sales and earnings in the first three quarters of 2013. Net sales increased 4.9 per cent over the same period of the previous year to 412.4 billion yen (£2.6 billion), operating income increased 13.8 per cent to 29.9 billion yen (£188.3 million) and net income increased 12.3 per cent to 19.6 billion yen (£123.5 million). The three totals were the highest ever in the nine-month period between January and September, although the company does point out that prior to shifting to calendar-year accounting in 2011 the same nine-month period corresponded to the fourth, first, and second quarters of the financial year.
