PGE periodically evaluates the likelihood of incurring costs under such indemnities based on the Company’s historical experience and the evaluation of the specific indemnities.</font></div></div>

In accordance with the new revenue standard, such revenues are presented separately from revenues from contracts with customers and classified as Alternative revenue programs, net of amortization on the condensed statement of income and comprehensive income as these amounts represent a contract with the regulator and not with customers. The activity within this line item is comprised of current period deferral adjustments, which can either be a collection from or a refund to customers, and is net of any related amortization. When amounts related to alternative revenue programs are ultimately included in prices and customer bills, the amounts are included within Revenues, net, with an equal and offsetting amount of amortization recorded on the Alternative revenue programs, net of amortization line item.</font></div><div style="line-height:120%;font-size:11pt;"><font style="font-family:inherit;font-size:11pt;"><br clear="none"/></font></div></div>

For such arrangements, PGE allocates revenue to each performance obligation based on its relative standalone selling price. PGE generally determines standalone selling prices based on the prices charged to customers.</font></div></div>
