(1) | The increase in non-current income tax receivable is mainly due to amended tax returns filed during fiscal 2013. |
(2) | The increase in pension assets was mainly due to a higher-than-expected rate of return on pension assets during the year and an increase in the discount rate at September 30, 2013 compared to September 30, 2012. |
(3) | The decrease in other investments was mainly due to the recognition of an other-than-temporary impairment loss and subsequent sale of an investment, combined with a reclassification of equity securities to long-term available-for-sale investment securities following a change in the Company's relationship with an investee. |
