Most notable was the promotion of Bob Patterson from chief financial officer to chief operating officer, where he successfully led the strong performances of our three business platforms, and the hiring of Rich Diemer to replace him as chief financial officer. Polymer formulations have advantages over metals, wood, rubber, glass and other traditional materials, which have resulted in the replacement of these materials across a wide spectrum of applications that range from automobile parts to construction materials. We capitalize replacements and betterments that increase the estimated useful life of an asset.

In the transportation industry, plastic has proven to be durable, lightweight and corrosion resistant while offering fuel savings, design flexibility and high performance, often replacing traditional materials such as metal and glass. Polymer formulations and structures have advantages over metals, wood, rubber, glass and other traditional materials, which have resulted in the replacement of these materials across a wide spectrum of applications. We capitalize replacements and improvements that increase the estimated useful life of an asset.
