The Company’s investments classified within Level 2 were primarily valued based on valuations obtained from a third-party pricing service. To estimate fair value, the pricing service utilizes industry-standard valuation models, including both income and market-based approaches for which all significant inputs are observable either directly or indirectly. The Company obtained documentation from the pricing service as to the methodology and summary of inputs used for the various types of securities. The pricing service maximizes the use of relevant observable inputs and minimizes the use of unobservable inputs. These observable inputs include reported trades and broker/dealer quotes of the same or similar securities, issuer credit spreads, benchmark securities and other observable inputs. The Company compares valuation information from the pricing service with other pricing sources to validate the reasonableness of the valuations.
