Schedule of the Plan's Investments With a Reported NAV

The following table sets forth a summary of the Plan’s investments with a reported NAV, which is a practical expedient to estimating fair value, as of November 30, 2016 and 2015.

	November 30,
(dollars in millions)	2016 Fair Value		2015 Fair Value
SEI Structured Credit Collective Fund(a)	$	26.9	$	22.2
Energy Debt Collective Investment Trust(b)	$	11.4	$	9.7
Core Property Collective Investment Trust(c)	$	21.8	$	23.1

(a) The SEI Structured Credit Collective Fund seeks to provide high general returns by investing in collateralized debt obligations (“CDO’s”) and other structured credit instruments. The SEI Structured Credit Collective Fund requires a two-year non-redemption period after which investments can be redeemed at any time; however, a 90 day redemption notification period is required. The Plan has satisfied all funding obligations related to this investment and has surpassed the two-year non-redemption period.

(b) The SEI Energy Debt Collective Funds seeks to generate high total returns by primarily investing in debt securities of U.S. and international energy companies denominated in U.S. dollars. The Fund will invest in investment grade bonds, below investment grade bonds, loans, rights issues, or equities of U.S. companies.  Equity investments will be limited. In most cases, equity investments will be attached to a debt investment for extending credit or if received in a restructuring, though the Sub-Adviser is permitted to add-on to an existing equity position through a secondary market transaction.

(c) The SEI Core Property Fund, (the "Fund") seeks both current income and long-term capital appreciation through investing in underlying funds that acquire, manage, and dispose of commercial real estate properties. The Fund expects to invest at least 85% of its assets in open-end core underlying funds focused on properties in the U.S. with "core" meaning high-quality, low-leveraged, income-generating office, industrial, retail, and multi-family properties, generally fully-leased to credit-worthy companies and governmental entities. Up to 5% of the Fund's net assets may be invested in liquid real estate strategies (publicly-traded REITs) for cash management purposes and the fund may have up to a 15% allocation to non-core sectors and strategies.
