The housing facilities leased to employees are not classified as investment properties; and manufacturing facilities leased to suppliers are not considered as investment properties since they cannot be sold separately and comprise only an insignificant portion of the entire facility.

The Company had recognized the pension cost and retirement benefit obligation under its defined benefit plans based on actuarial valuations performed in conformity with R.O.C. GAAP.

In addition, under R.O.C. GAAP, a minimum pension liability should be recognized in the balance sheet.

The Company has evaluated significant differences between current accounting policies and Accounting Standards Used in Preparation of the Parent Company Only Financial Statements for the Company’s subsidiaries and associates accounted for using the equity method. The significant difference is mainly due to the adjustment to employee benefits.

In addition, if the investor subscribes to additional shares of associates and joint ventures that is disproportionate to its existing ownership percentage and results in a decrease in the investor’s ownership percentage in the associate and joint venture, the resulting carrying amount of the investment differs from the amount of the investor’s share in the equity of the associates and joint venture. Under R.O.C. GAAP, the investor records such a difference as an adjustment to the carrying amount of the investment with the corresponding amount charged or credited to capital surplus. Under Accounting Standards Used in Preparation of the Parent Company Only Financial Statements, such a difference is still adjusted to carrying amount of the investment and capital surplus. If the investor’s ownership interest in an associate and joint venture decreases, the proportionate amount of the gains or losses previously recognized in other comprehensive income in relation to that associate and joint venture shall be reclassified to profit or loss on the same basis as would be required if the associate and joint venture had directly disposed of the related assets or liabilities.

As of December 31, 2012 and January 1, 2012, as a result of the differences mentioned above, investment accounted for using the equity method was adjusted for a decrease of NT$113,720 thousand and NT$57,462 thousand, respectively; foreign currency translation reserve was adjusted for a decrease of NT$43 thousand and an increase of NT$5 thousand, respectively; capital surplus was adjusted for a decrease of NT$462,469 thousand and NT$374,695 thousand, respectively.
