To the extent that these contracts are derivatives, MGE assesses whether or not the normal purchases or normal sales exclusion applies. For contracts to which this exclusion cannot be applied, MGE Energy and MGE recognize such derivatives in the consolidated balance sheets at fair value</font><font style="font-family:Times New Roman;font-size:10pt;">.</font><font style="font-family:Times New Roman;font-size:10pt;"> The majority of MGE's derivative activities are conducted in accordance with its electric and gas risk management program, which is approved by the PSCW and limits the volume MGE can hedge with specific risk management strategies. The maximum length of time over which cash flows related to energy commodities can be hedged </font><font style="font-family:Times New Roman;font-size:10pt;">is </font><font style="font-family:Times New Roman;font-size:10pt;">four years.</font><font style="font-family:Times New Roman;font-size:10pt;"> If the derivative qualifies for regulatory deferral, the derivatives are marked to fair value and are offset with a corresponding regulatory asset or liability. The deferred gain or loss is recognized in earnings in the delivery month applicable to the instrument. Gains and losses related to hedges qualifying for regulatory treatment are recoverable in gas rates through the PGA or in electric rates as a component of the fuel rules mechanism.</font></p>
