For those interested in balance sheets and in wider picture of Ricoh's business model, which includes cameras among many others, take a look at this presentation.
Ricoh Co., Ltd. Consolidated Results for the year ended March 31, 2013
Ricoh had several, rather large strategic purchases during the last several years that were intended to strengthen the company globally in the long term. They have incurred restructuring costs. However, restructuring in reality means gaining much more efficiency.
You will notice lots of operational and restructuring / integrating costs in fiscal 2011 and fiscal 2012 (Pentax is one of them), which are already disappearing and about to disappear completely in the next Japanese fiscal year (March 2013 – March 2014).
Despite that, despite slow economy in Japan and roughing economy worldwide, they fare rather well.
