Long-Term Debt Financing Transactions During 2017, PSEG and its subsidiaries had the following Long-Term Debt issuances, maturities and redemptions: PSEG
• | entered into an agreement for a new term loan maturing June 2019. The term loan has a balance of $700 million at an interest rate of 1 month LIBOR + 0.80% and can be terminated at any time without penalty,

Short-Term Liquidity PSEG meets its short-term liquidity requirements, as well as those of Power, primarily with cash and through the issuance of commercial paper. PSE&G maintains its own separate commercial paper program to meet its short-term liquidity requirements. Each commercial paper program is fully back-stopped by its own separate credit facilities. The commitments under the $4.2 billion credit facilities are provided by a diverse bank group. As of December 31, 2017, the total available credit capacity was $3.5 billion. As of December 31, 2017, no single institution represented more than 8% of the total commitments in the credit facilities. As of December 31, 2017, the total credit capacity was in excess of the anticipated maximum liquidity requirements over PSEG’s 12-month planning horizon. Each of the credit facilities is restricted as to availability and use to the specific companies as listed in the following table; however, if necessary, the PSEG facilities can also be used to support our subsidiaries’ liquidity needs. The total credit facilities and available liquidity as of December 31, 2017 were as follows:

(A) | The primary use of PSEG’s and PSE&G’s credit facilities is to support their respective Commercial Paper Programs under which as of December 31, 2017, PSEG had $542 million outstanding at a weighted average interest rate of 1.89%. PSE&G had no amounts outstanding under its Commercial Paper Program as of December 31, 2017.
Fair Value of Debt The estimated fair values, carrying amounts and methods used to determine fair value of long-term debt as of December 31, 2017 and 2016 are included in the following table and accompanying notes as of December 31, 2017 and 2016. See Note 17. Fair Value Measurements for more information on fair value guidance and the hierarchy that prioritizes the inputs to fair value measurements into three levels.
|  |  | December 31, 2017 |  | December 31, 2016 |
|  |  | Carrying Amount |  | Fair Value |  | Carrying Amount |  | Fair Value |
|  |  | Millions |
| Long-Term Debt: |  |  |  |  |  |  |  |  |
| PSEG (A) (B) |  | $ | 2,091 |  |  | $ | 2,081 |  |  | $ | 1,195 |  |  | $ | 1,185 |  |
| PSE&G (B) |  | 8,591 |  |  | 9,322 |  |  | 7,818 |  |  | 8,240 |  |
| Power (B) |  | 2,386 |  |  | 2,659 |  |  | 2,382 |  |  | 2,578 |  |
|  |  | $ | 13,068 |  |  | $ | 14,062 |  |  | $ | 11,395 |  |  | $ | 12,003 |  |
(A) | As of December 31, 2017 and 2016, fair value includes floating rate term loans of $700 million and $500 million, respectively. The fair values of the term loan debt (Level 2 measurement) approximate the carrying values because the interest payments are based on LIBOR rates that are reset monthly and the debt is redeemable at face value by PSEG at any time.
(B) | Given that these bonds do not trade actively, the fair value amounts of taxable debt securities (primarily Level 2 measurements) are generally determined by a valuation model that is based on a conventional discounted cash flow methodology and utilizes assumptions of current market pricing curves. In order to incorporate the credit risk into the discount rates, pricing is obtained (i.e. U.S. Treasury rate plus credit spread) based on expected new issue pricing across each of the companies’ respective debt maturity spectrum. The credit spreads of various tenors obtained from this information are added to the appropriate benchmark U.S. Treasury rates in order to determine the current market yields for the various tenors. The yields are then converted into discount rates of various tenors that are used for discounting the respective cash flows of the same tenor for each bond or note.

As of December 31, 2017, the total credit capacity was in excess of the anticipated maximum liquidity requirements over PSEG’s 12-month planning horizon. Each of the credit facilities is restricted as to availability and use to the specific companies as listed in the following table; however, if necessary, the PSEG facilities can also be used to support our subsidiaries’ liquidity needs. The total credit facilities and available liquidity as of December 31, 2017 were as follows:

(A) | The primary use of PSEG’s and PSE&G’s credit facilities is to support their respective Commercial Paper Programs under which as of December 31, 2017, PSEG had $542 million outstanding at a weighted average interest rate of 1.89%. PSE&G had no amounts outstanding under its Commercial Paper Program as of December 31, 2017.
Fair Value of Debt The estimated fair values, carrying amounts and methods used to determine fair value of long-term debt as of December 31, 2017 and 2016 are included in the following table and accompanying notes as of December 31, 2017 and 2016. See Note 17. Fair Value Measurements for more information on fair value guidance and the hierarchy that prioritizes the inputs to fair value measurements into three levels.

|  |  | $ | 13,068 |  |  | $ | 14,062 |  |  | $ | 11,395 |  |  | $ | 12,003 |  |
(A) | As of December 31, 2017 and 2016, fair value includes floating rate term loans of $700 million and $500 million, respectively. The fair values of the term loan debt (Level 2 measurement) approximate the carrying values because the interest payments are based on LIBOR rates that are reset monthly and the debt is redeemable at face value by PSEG at any time.
(B) | Given that these bonds do not trade actively, the fair value amounts of taxable debt securities (primarily Level 2 measurements) are generally determined by a valuation model that is based on a conventional discounted cash flow methodology and utilizes assumptions of current market pricing curves. In order to incorporate the credit risk into the discount rates, pricing is obtained (i.e. U.S. Treasury rate plus credit spread) based on expected new issue pricing across each of the companies’ respective debt maturity spectrum. The credit spreads of various tenors obtained from this information are added to the appropriate benchmark U.S. Treasury rates in order to determine the current market yields for the various tenors. The yields are then converted into discount rates of various tenors that are used for discounting the respective cash flows of the same tenor for each bond or note.

Short-Term Liquidity PSEG meets its short-term liquidity requirements, as well as those of Power, primarily with cash and through the issuance of commercial paper.

As of December 31, 2017, no single institution represented more than 8% of the total commitments in the credit facilities. As of December 31, 2017, the total credit capacity was in excess of the anticipated maximum liquidity requirements over PSEG’s 12-month planning horizon.
