The company also announced the formation of a new venture, OsteoArthritis Centers of America, for the treatment of osteoarthritis, degenerative joint disease and other musculoskeletal conditions. The first of these new centers opened in June in Wellington, Florida.

We have rated Quaker Chemical a buy since May 2007. On July 30, 2008, the company announced record net sales and net income for the second quarter of fiscal 2008. Net sales increased 15.0% year over year, primarily due to higher sales prices and favorable foreign exchange translations, while net income increased 4.0%. At 41 cents per share, earnings per diluted share were equal to that of the second quarter of fiscal 2007. Operating cash flow increased $14.3 million from a year ago, which led to a decrease in the company's net debt-to-total-capital ratio from 32.00% at the end of fiscal 2007 to 28.00% at the end of the most-recent quarter.
