Hsinchu, Taiwan, June 14, 2012 - ChipMOS TECHNOLOGIES (Bermuda) LTD. ("ChipMOS" or the "Company") (NASDAQ: IMOS) today announced its Board of Directors has adopted a dividend policy. The dividend policy is the first in the Company's history. Certain actions required to declare dividends under the policy will be submitted for approval by our shareholders at the Company's Annual General Meeting ("AGM") in August 2012.

The dividend policy would permit the Company to distribute an annual dividend to shareholders from retained earnings equal to 0.8% to 1.2% of the Company's book value (approximately US$0.10 to US$0.15 per share at April 30, 2012). Declaring dividends under the policy is subject to the Company's assessment of its operating plans and market conditions at that time, and its ability to maintain compliance with all applicable regulatory and financial criteria, including passing a solvency and asset test, as required by the Companies Act 1981 of Bermuda (as amended).

The Company presently passes the solvency and asset test. It expects to have adequate retained earnings to declare the first dividend under the new policy in the fourth quarter of 2012.

S.J. Cheng, Chairman and Chief Executive Officer of ChipMOS, said, "This is another milestone event for ChipMOS in the evolution of the Company as a long-term leader. The dividend policy directly reflects our Board and management's expectation that ChipMOS's financial resources will support cash distributions to our shareholders, furthering our commitment to good governance and to building value for our shareholders."

(File Nos. 333-181367) and will be a part thereof from the date on which this report is furnished, to the extent not superseded by documents or reports subsequently filed or furnished.
