Invested in the AQR Delta Offshore Fund. The fund seeks to produce high risk-adjusted returns while targeting a low long-term average correlation to traditional markets. The fund invests internationally in a broad range of instruments, including, but not limited to, equities, currencies, convertible securities, futures, forwards, options, swaps, and other derivative products. The fair value of the hedge fund is estimated using the net asset value (NAV) of the investment as a practical expedient for fair value. We have the ability to redeem these investments at NAV within the near term. During 2016, we adopted ASU 2015-07, which removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the NAV per share practical expedient. As such, the AQR Delta Offshore Fund has not been classified within the fair value hierarchy tables as of December 31, 2016 and 2015.

The fair value of the real estate fund is estimated using NAV of the investment as a practical expedient for fair value. Amounts realized on the sale of these investments may differ from the calculated values. We have the ability to redeem the real estate investments with a 110-calendar-day written notice prior to a quarterly trade date. During 2016, we adopted ASU 2015-07, which removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the NAV per share practical expedient. As such, the Russell Real Estate Equity Fund has not been classified within the fair value hierarchy tables as of December 31, 2016 and 2015.

Equity and fixed-income securities represent common collective trusts managed and valued by Russell Trust Company, the administrator of the funds. While the underlying assets are actively traded on an exchange, the funds are not. The investments in equity and fixed-income securities are considered to have a readily determinable fair value because the fair value per share (unit) is determined and published and is the basis for current transactions. We have the ability to redeem these equity and fixed-income securities with a one-day notice.
