We determine the fair value of our security holdings based on pricing from our service providers and market prices from industry-standard independent data providers. Such market prices may be quoted prices in active markets for identical assets (Level 1 inputs) or pricing determined using inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs), such as yield curve, volatility factors, credit spreads, default rates, loss severity, current market and contractual prices for the underlying instruments or debt, broker and dealer quotes, as well as other relevant economic measures.

Our equity investments in privately-held companies are not included in the table above and are discussed in Note 3. See Note 8 for the fair value measurement of our derivative contracts and Note 10 for the fair value measurement of our long-term debt, which are also not included in the table above.
