Capital Lease—PGE has entered into agreements to purchase natural gas transportation capacity to serve the Carty Generating Station (Carty), a 440 MW natural gas-fired baseload resource located in eastern Oregon, adjacent to the Boardman coal-fired generating plant. A new 24-mile natural gas pipeline, Carty Lateral, was constructed to serve the Carty facility. The Company has entered into a 30-year agreement to purchase the entire capacity of Carty Lateral, which is approximately 175,000 decatherms per day. At the end of the initial contract term, the Company has the option to renew the agreement in continuous three-year increments with at least 24-months prior written notice. For accounting purposes, this transportation capacity agreement is treated as a capital lease.

As of June 30, 2016, a capital lease asset of $57 million was reflected within Electric utility plant, and accumulated amortization of such assets of $2 million reflected within Accumulated depreciation and amortization in the table above. The present value of the future minimum lease payments due under the agreement included $3 million within Accrued expenses and other current liabilities and $52 million in Other noncurrent liabilities on the condensed consolidated balance sheets. For ratemaking purposes capital leases are treated as operating leases; therefore, in accordance with the accounting rules for regulated operations, the amortization of the leased asset is based on the rental payments recovered from customers. Also for ratemaking purposes, such rental payments were capitalized to the Carty project prior to its in service date of July 29, 2016. Amortization of the leased asset of $2 million and interest expense of $3 million has been capitalized to Construction work-in-progress (CWIP) as of June 30, 2016.

For the remainder of 2016, PGE expects $3 million in minimum lease payments, with $2 million imputed interest and present value of net minimum lease payments of $1 million. As of June 30, 2016, PGE’s estimated future minimum lease payments, for the following five years and thereafter, net of administrative costs such as property taxes, insurance and maintenance are as follows (in millions):

Credit Facilities

As of June 30, 2016, PGE had a $500 million revolving credit facility scheduled to expire in November 2019.

Pursuant to the terms of the agreement, the revolving credit facility may be used for general corporate purposes, as backup for commercial paper borrowings, and to permit the issuance of standby letters of credit. PGE may borrow for one, two, three, or six months at a fixed interest rate established at the time of the borrowing, or at a variable interest rate for any period up to the then remaining term of the applicable credit facility. The revolving credit facility contains provisions for two one-year extensions subject to approval by the banks, requires annual fees based on PGE’s unsecured credit ratings, and contains customary covenants and default provisions, including a requirement that limits consolidated indebtedness, as defined in the agreement, to 65% of total capitalization. As of June 30, 2016, PGE was in compliance with this covenant with a 51.1% debt-to-total capital ratio.

The Company has a commercial paper program under which it may issue commercial paper for terms of up to 270 days, limited to the unused amount of credit under the revolving credit facility.

PGE classifies any borrowings under the revolving credit facility and outstanding commercial paper as Short-term debt on the condensed consolidated balance sheets.

Under the revolving credit facility, as of June 30, 2016, PGE had no borrowings, commercial paper, or letters of credit issued. As of June 30, 2016, the aggregate unused available credit capacity under the revolving credit facility was $500 million.

In addition, PGE has four letter of credit facilities that provide a total of $160 million capacity under which the Company can request letters of credit for original terms not to exceed one year. The issuance of such letters of credit is subject to the approval of the issuing institution. Under these four facilities, $92 million of letters of credit were outstanding, as of June 30, 2016.

Pursuant to an order issued by the Federal Energy Regulatory Commission (FERC), the Company is authorized to issue short-term debt in an aggregate amount of up to $900 million through February 6, 2018.

Long-term Debt

In May 2016, PGE entered into an unsecured credit agreement with certain financial institutions, under which the Company may obtain three separate term loans in an aggregate principal amount of $200 million. During the second quarter of 2016, PGE obtained the following two term loans:


•	$50 million on May 4, 2016; and


•	$75 million on June 15, 2016.

The Company has until October 31, 2016 to obtain the third term loan in the amount of up to $75 million. The term loan interest rates are set at the beginning of the interest period for periods of 1-month, 3-months or 6-months, as selected by PGE and are based on the London Interbank Offered Rate (LIBOR) plus 63 basis points, approximately 1.1% as of June 30, 2016, with no other fees.

The credit agreement expires November 30, 2017, at which time any amounts outstanding under the term loans become due and payable. Upon the occurrence of certain events of default, the Company’s obligations under the credit agreement may be accelerated. Such events of default include payment defaults to lenders under the credit agreement, covenant defaults and other customary defaults for financings of this type.

During the six months ended June 30, 2016, PGE had the following First Mortgage Bonds (FMBs) long-term debt transactions, all of which occurred in early January:


•	Issued $140 million of 2.51% Series FMBs due 2021;


•	Repaid $75 million of 5.80% Series FMBs, due in 2018; and


•	Repaid $58 million of 3.81% Series FMBs, due in 2017.

Due to the anticipated repayment of the $133 million in early January 2016, this amount of long-term debt was classified as current on the Company’s condensed consolidated balance sheets as of December 31, 2015.
