Financial Assets Classified as Level 2 and Level 3 | The following financial instruments are classified under Level 2:
Type of financial instrument |  | Model used in valuation |  | Description of unobservable inputs
● Mortgage and private bonds |  | Present Value of Cash Flows Model |  | Internal Rates of Return (“IRRs”) are provided by RiskAmerica, according to the following criterion: If, at the valuation day, there are one or more valid transactions at the Santiago Stock Exchange for a given nemotechnic, the reported rate is the weighted average amount of the observed rates. In the case there are no valid transactions for a given mnemonic on the valuation day, the reported rate is the IRR base from a reference structure, plus a spread model based on historical spread for the same item or similar ones.
● Time deposits |  | Present Value of Cash Flows Model |  | IRRs are provided by RiskAmerica, according to the following criterion: If, at the valuation day, there are one or more valid transactions at the Santiago Stock Exchange for a given mnemonic, the reported rate is the weighted average amount of the observed rates. In the case there are no valid transactions for a given mnemonic on the valuation day, the reported rate is the IRR base from a reference structure, plus a spread model based on issuer curves.
● Constant Maturity Swaps (CMS), FX and Inflation Forward (Fwd) , Cross Currency Swaps (CCS), Interest Rate Swap (IRS) |  | Present Value of Cash Flows Model |  | IRRs are provided by ICAP, GFI, Tradition, and Bloomberg according to this criterion: With published market prices, a valuation curve is created by the bootstrapping method and is then used to value different derivative instruments.
● FX Options |  | Black-Scholes |  | Formula adjusted by the volatility simile (implicit volatility), Prices (volatility) are provided by BGC Partners, according to this criterion: With published market prices, a volatility parameter is created by interpolation and then these volatilities are used to value options.
● Guarantee deposits, guarantee received (Threshold) |  | Present Value of Cash Flows Model |  | Collateral associated to derivatives financial contracts: Average trading swap (CMS), FX and inflation Forward, Cross Currency Swap (CCS), Interest Rate Swap (IRS) y FX options.
The following financial instruments are classified under Level 3:
Type of financial instrument |  | Model used in valuation |  | Description of unobservable inputs
● Caps/Floors/Swaptions |  | Black Normal model for Cap/Floors and Swaptions |  | There is unobservable input of implied volatility.
|  | Black – Scholes |  | There is unobservable input of implied volatility.
|  | Hull-White |  | Hybrid HW model for rates and Brownian motion for FX. There is unobservable volatility input
|  | FRA Implicit |  | Start FW not supported by Murex (platform) due to UF FW estimation
● CCS, IRS, CMS at TAB rates |  | Present Value of Cash Flows Model |  | - Valuation obtained using interest curve interpolating to maturity of flows, however, TAB is not a directly observable variable nor correlated to any market input. - Valuation using prices of instruments with similar characteristics plus a liquidity penalty rate.
● CCS (maturity> 30 years) |  | Present Value of Cash Flows Model |  | The rates are provided by ICAP, GFI, Tradition and Bloomberg according following criteria: Using the published market prices, the valuation curve is constructed using the bootstrapping method and this curve is then used to value the different derivatives.
● Debt instruments (in our case, low liquidity bonds) |  | Risk-free spread Model |  | Stochastic dynamic model to obtain discount rate.
● Loans and account receivable at FVOCI |  | Present Value of Cash Flows Model |  | Measured by discounting estimated cash flow using the interest rate of new contracts.
