INVESTMENTS IN EQUITY SECURITIES
 
Investments in securities classified as available-for-sale securities are reported at fair value, using either specific identification or average cost to determine the cost for computing gains or losses.  Any unrealized gains or losses on available-for-sale securities are included in other comprehensive income.
 
The table below summarizes investments in equity securities by IDACORP and Idaho Power as of June 30, 2012 and December 31, 2011 (in thousands of dollars).

At the end of each reporting period, IDACORP and Idaho Power analyze securities in loss positions to determine whether they have experienced a decline in market value that is considered other-than-temporary.  At June 30, 2012 and December 31, 2011, one security was in an immaterial unrealized loss position. No other-than-temporary impairment was recognized for this security due to the limited severity and duration of the unrealized loss position.
 
There were no sales of available-for-sale securities during the three and six months ended June 30, 2012 or 2011.
