We have a senior secured revolving credit facility which provides for total maximum advances of $1.5 billion with the aggregate amount outstanding at any point in time of $500 million and which consists of two components, the G&I Facility and the PF Facility. The “G&I Facility” can be used to leverage certain qualifying government and institutional financings entered into by us and the “PF Facility” can be used to leverage certain qualifying project financings entered into by us.

The facility was originally entered into in 2013 and has been amended a number of times, including in January 2016. The effect of the various amendments has been to increase the size, flexibility and allocation of the facility and extend the termination date to July 19, 2019. The limit of borrowing at any point in time and the total maximum advances is summarized below:

Loans under the G&I Facility bear interest at a rate equal to the London Interbank Offered Rate (“LIBOR”) plus 1.5% or, under certain circumstances, 1.5% plus the highest of (i) the Federal Funds Rate plus 0.5%, (ii) the rate of interest publicly announced by Bank of America from time to time as its “prime rate,” and (iii) LIBOR plus 1.0%. Loans under the PF Facility bear interest at a rate equal to LIBOR plus 2.5% or, under certain circumstances, 2.5% plus the highest of (i) the Federal Funds Rate plus 0.5%, (ii) the rate of interest publicly announced by Bank of America from time to time as its “prime rate,” and (iii) LIBOR plus 1.0%. Under the PF Facility, we also have the option to borrow at a fixed rate of interest until the expiration of the credit facility in July 2019. The fixed rate is determined by agreement with the Administrative Agent and is based on the prevailing US SWAP rate of an equivalent term to the average-life of the fixed rate portion of the borrowing plus an agreed upon margin. The loans are made through wholly-owned special purpose subsidiaries (the “Borrowers”) and we have guaranteed the obligations of the Borrowers under the credit facility pursuant to (x) a Continuing Guaranty, dated July 19, 2013, and (y) a Limited Guaranty, dated July 19, 2013, both as amended and restated.

Any financing we propose to be included in the borrowing base as collateral under the facility is subject to the approval of the administrative agent in its sole discretion and the payment of a placement fee. We may, with the consent of the administrative agent, borrow against new projects before such projects become Approved Financings (as defined in the PF Facility loan agreement) but after they have been pledged as collateral. The amount eligible to be drawn under the facility for purposes of financing such investments will be based on a discount to the value of each investment or an applicable valuation percentage. Under the G&I Facility, the applicable valuation percentage for non-delinquent investments is 85% in the case of a U.S. federal government obligor, 80% in the case of an institutional obligor or a state and local obligor, and with respect to other obligors or in certain circumstances, such other percentage as the administrative agent may prescribe. Under the PF Facility, the applicable valuation percentage is 67% or such other percentage as the administrative agent may prescribe. The sum of approved financings after taking into account the valuation percentages and any changes in the valuation of the financings in accordance with the loan agreements determines the borrowing capacity, subject to the overall facility limits described above.

The following table provides additional detail on our credit facility as of June 30, 2016 and December 31, 2015:

We incurred approximately $13 million of costs associated with the credit facility that have been capitalized (included in other assets on the condensed consolidated balance sheets) and are being amortized on a straight-line basis over the term of the Loan Agreements. On each monthly payment date, the Borrowers shall also pay to the administrative agent, for the benefit of the lenders, certain availability fees for each Loan Agreement equal to 0.50%, divided by 360, multiplied by the excess of the available borrowing capacity under each component of the credit facility over the actual amount borrowed under such component.

The credit facility contains terms, conditions, covenants, and representations and warranties that are customary and typical for a transaction of this nature, including various affirmative and negative covenants, and limitations on the incurrence of liens and indebtedness, investments, fundamental organizational changes, dispositions, changes in the nature of business, transactions with affiliates, use of proceeds and stock repurchases.

The credit facility also includes customary events of default, including the existence of a default in more than 50% of underlying financings. The occurrence of an event of default may result in termination of the credit facility, acceleration of amounts due under the credit facility, and accrual of default interest at a rate of LIBOR plus 2.50% in the case of the G&I Facility and at a rate of LIBOR plus 5.00% in the case of the PF Facility.

We were in compliance with the required financial covenants described below at each quarterly reporting date that such covenants were applicable:
