After evaluating the financial assets carried at cost, Chunghwa and its subsidiaries determined the following investments were  impaired and recognized impairment losses for the years ended December 31, 2010 and 2011: The above investments do not have quoted market prices in an active market and the fair values cannot be reliably measured;  therefore, these investments are carried at original cost.  As part of the government’s effort to upgrade the existing telecommunications infrastructure, Chunghwa and other public utility  companies were required by the ROC government to contribute a total of NT$1,000 million to a Piping Fund administered by  the Taipei City Government. This fund was used to finance various telecommunications infrastructure projects. 16.  PROPERTY, PLANT AND EQUIPMENT, NET 15.
