Loan Risk Ratings

As further described in Note 2, our Manager evaluates our loan portfolio on a quarterly basis. In conjunction with our quarterly loan portfolio review, our Manager assesses the risk factors of each loan, and assigns a risk rating based on several factors. Factors considered in the assessment include, but are not limited to, risk of loss, current LTV, debt yield, collateral performance, structure, exit plan, and sponsorship. Loans are rated “1” (less risk) through “5” (greater risk), which ratings are defined in Note 2.

The following table allocates the principal balance and net book value of our loans receivable based on our internal risk ratings ($ in thousands):

Unfunded commitments will primarily be funded to finance our borrowers’ construction or development of real estate-related assets, capital improvements of existing assets, or lease-related expenditures. These commitments will generally be funded over the term of each loan, subject in certain cases to an expiration date.

Our floating rate loans are indexed to various benchmark rates, with 83% and 92% of our floating rate loans by principal balance indexed to USD LIBOR as of September 30, 2018 and December 31, 2017, respectively. In addition to cash coupon, all-in yield includes the amortization of deferred origination and extension fees, loan origination costs, and purchase discounts, as well as the accrual of exit fees. Cash coupon and all-in yield assume applicable floating benchmark rates for weighted-average calculation.

Maximum maturity assumes all extension options are exercised by the borrower, however our loans may be repaid prior to such date. As of September 30, 2018, 86% of our loans by principal balance were subject to yield maintenance or other prepayment restrictions and 14% were open to repayment by the borrower without penalty. As of December 31, 2017, 75% of our loans were subject to yield maintenance or other prepayment restrictions and 25% were open to repayment by the borrower without penalty.
