⁽¹⁾

TEP’s variable rate bonds are backed by $186 million in LOCs issued pursuant to TEP’s Credit Agreement which expires in November 2016 and TEP’s $37 million Reimbursement Agreement which expires in December 2014. Although the variable rate bonds mature between 2018 and 2032, the above table reflects a redemption or repurchase of such bonds in 2014 and 2016 as though the LOCs terminate without replacement upon expiration of the TEP Credit Agreement.

⁽²⁾	The repayment of TEP Unsecured Notes is not reduced by the approximately $1 million discount.
