The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the statement of financial position. See Note 1— "Basis of Presentation" of the "Notes to Interim Consolidated Financial Statements" under Part I, Item 1 in this report.

Quantitative Information About Significant Unobservable Inputs

The following table presents quantitative information about the significant unobservable inputs used for certain of our Level 3 fair value measurements at June 30, 2015 and December 31, 2014. We have not included in this table our venture capital and private equity fund investments (fair value accounting) as we use net asset value per share (as obtained from the general partners of the investments) as a practical expedient to determine fair value.

(1)

In determining the fair value of our other venture capital investment portfolio, we evaluate a variety of factors related to each underlying private portfolio company including, but not limited to, actual and forecasted results, cash position, recent or planned transactions and market comparable companies. Additionally, we have ongoing communication with the portfolio companies and venture capital fund managers, to determine whether there is a material change in fair value. These factors are specific to each portfolio company and a weighted average or range of values of the unobservable inputs is not meaningful.


(2)	We adjust quoted market prices of public companies, which are subject to certain sales restrictions. Sales restriction discounts generally range from 10% to 20% depending on the duration of the sales restrictions, which typically range from 3 to 6 months.


(3)	Our marketability discount is applied to all private company warrants to account for a general lack of liquidity due to the private nature of the associated underlying company. The quantitative measure used is based upon various option-pricing models. On a quarterly basis, a sensitivity analysis is performed on our marketability discount.

(4)

We adjust the contractual remaining term of private company warrants based on our estimate of the actual remaining life, which we determine by utilizing historical data on cancellations and exercises. At June 30, 2015, the weighted average contractual remaining term was 5.79 years, compared to our estimated remaining life of 2.60 years. On a quarterly basis, a sensitivity analysis is performed on our remaining life assumption.

Summary of Estimated Fair Values of Financial Instruments Not Carried at Fair Value

Letters of credit are carried at their fair value, which was equivalent to the residual premium or fee at June 30, 2015 and December 31, 2014. Commitments to extend credit and letters of credit typically result in loans with a market interest rate if funded.

The following fair value hierarchy table presents the estimated fair values of our financial instruments that are not carried at fair value at June 30, 2015 and December 31, 2014:

Venture capital and private equity fund investments within non-marketable securities (fair value accounting) include investments made by our managed funds of funds and one of our direct venture funds. These investments represent investments in venture capital and private equity funds that invest primarily in U.S. and global technology and life science & healthcare companies. Included in the fair value and unfunded commitments of fund investments under fair value accounting are $112 million and $8 million, respectively, attributable to noncontrolling interests. It is estimated that we will receive distributions from the fund investments over the next 10 to 13 years, depending on the age of the funds and any potential extensions of terms of the funds.
