Short-Term Debt and CreditFacility

AtJune 30, 2016, there was $26.5 million in advances from OGE Energy compared to $333.6 million in advances to OGE Energy at December 31, 2015. OG&E has an intercompany borrowing agreement with OGE Energy whereby OG&E has access to up to$400.0 millionof OGE Energy's revolving credit amount.  This agreement has a termination date of December 13, 2018. At June 30, 2016, there werenointercompany borrowings under this agreement.OG&E has a$400.0 million unsecured five-year revolving credit facility which isavailable to back up OG&E's commercial paper borrowings and to provide revolving credit borrowings.  This bank facility can also be used as a letter of credit facility.AtJune 30, 2016, there were$1.7 millionsupporting letters of credit at a weighted-average interest rate of0.95 percent. There were nooutstanding borrowings under this revolving credit agreement and nooutstanding commercial paper borrowings atJune 30, 2016.

As of June 30, 2016, the commitment of $8.7 million of OG&E's credit facility was not extended and unless the non-extending lender is replaced in accordance with the terms of the credit facility, the commitment will expire December 13, 2017.

OGE Energy's and OG&E's ability to access the commercial paper market could be adversely impacted by a credit ratings downgrade or major market disruptions.Pricing grids associated withOGE Energy's and OG&E'screditfacilitiescould cause annual fees and borrowing rates to increase if an adverse rating impact occurs. The impact of any future downgrade could include an increase in the costs ofOGE Energy's and OG&E'sshort-term borrowings, but a reduction inOGE Energy's and OG&E'scredit ratings would not result in any defaults or accelerations.Any future downgrade of OG&Ecould also lead to higher long-term borrowing costs and, if below investment grade, would requireOG&Eto post collateral or letters of credit.

OG&E must obtain regulatory approval from the FERC in order to borrow on a short-term basis.OG&E has the necessary regulatory approvals to incur up to$800.0 millionin short-term borrowings at any one time for a two-year period beginning January 1, 2015 and ending December 31, 2016.
