Notes to Consolidated Financial Statements (Continued)
(18) Fair value measurements (Continued)
Gains and losses included in earnings are included as components of investment gains/losses, derivative gains/losses and
other revenues, as appropriate and are primarily related to changes in the values of derivative contracts and settlement
transactions. Gains and losses included in other comprehensive income are included as components of the net change in
unrealized appreciation of investments and the reclassification of investment appreciation in earnings, as appropriate in the
Consolidated Statements of Comprehensive Income.
In 2013, we transferred the fair value measurements of the GS Warrants and GE Warrants out of Level 3 because we
concluded that the unobservable inputs were no longer significant. In 2011, our investments in GS Preferred and GE Preferred
were redeemed at the options of the issuers and were transferred out of Level 3 in the quarterly periods prior to the redemptions.
In 2011, we acquired investments in BAC Preferred and BAC Warrants for an aggregate cost of $5.0 billion.
Quantitative information as of December 31, 2013, with respect to assets and liabilities measured and carried at fair value
on a recurring basis with the use of significant unobservable inputs (Level 3) follows (in millions).

Other investments currently consist of investments that were acquired in a few relatively large private placement
transactions and include preferred stocks and common stock warrants. These investments are subject to contractual restrictions
on transferability and/or provisions that prevent us from economically hedging our investments. In applying discounted
estimated cash flow techniques in valuing the perpetual preferred stocks, we made assumptions regarding the expected durations
of the investments, as the issuers may have the right to redeem or convert these investments. We also made estimates regarding
the impact of subordination, as the preferred stocks have a lower priority in liquidation than debt instruments of the issuers,
which affected the discount rates used. In valuing the common stock warrants, we used a warrant valuation model. While most
of the inputs to the model are observable, we are subject to the aforementioned contractual restrictions. We have applied
discounts with respect to the contractual restrictions. Increases or decreases to these inputs would result in decreases or
increases to the fair values of the investments.
Our equity index put option and credit default contracts are not exchange traded and certain contract terms are not standard
in derivatives markets. For example, we are not required to post collateral under most of our contracts and many contracts have
long durations, and therefore are illiquid. For these and other reasons, we classified these contracts as Level 3. The methods we
use to value these contracts are those that we believe market participants would use in determining exchange prices with respect
to our contracts.
We value equity index put option contracts based on the Black-Scholes option valuation model. Inputs to this model
include current index price, contract duration, dividend and interest rate inputs (including a Berkshire non-performance input)
which are observable. However, we believe that the valuation of long-duration options using any model is inherently subjective,
given the lack of observable transactions and prices, and acceptable values may be subject to wide ranges. Expected volatility
inputs represent our expectations after considering the remaining duration of each contract and that the contracts will remain
outstanding until the expiration dates without offsetting transactions occurring in the interim. Increases or decreases in the
volatility inputs will produce increases or decreases in the fair values of the liabilities.
