| @ | At March 31, 2026, the aggregate cost of investments, including derivatives, for federal tax purposes (in thousands) was $970,363 and the net unrealized appreciation of investments based on that cost was $296,500 which is comprised of $353,954 aggregate gross unrealized appreciation and $57,454 aggregate gross unrealized depreciation. Because tax adjustments are calculated annually, these amounts do not reflect tax adjustments.

Emerging Markets Equity Portfolio

The Fair Value Measurements and Disclosures Topic of the FASB Accounting Standards Codification defines fair value as the price that a Fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. It establishes and requires disclosure of a fair value hierarchy, separately for each major category of asset and liability, which segregates fair value measurements into levels. A summary of the fair value hierarchy is described below:

Level 1 - fair value is determined by unadjusted quoted prices in active markets for identical securities or derivatives

Level 2 - fair value is determined by other significant observable inputs

Level 3 - fair value is determined by significant unobservable inputs

The categorization of a value determined for a financial instrument within the hierarchy is based upon the pricing transparency of the instrument and does not necessarily correspond to the Portfolio's perceived risk of that instrument.

The following is a summary of the inputs used in valuing the Portfolio's Investments at March 31, 2026.
