The discount rates for the net periodic costs for Puget Energy and PSE were different because of the discount rates in effect as of February 5, 2009, the date of the merger of Puget Energy with Puget Holdings.

1.	Non – US Equity investments are comprised of a (1) mutual fund; and a (2) commingled fund. The investment in the mutual fund is valued using quoted market prices multiplied by the number of shares owned as of December 31, 2011. The investment in the commingled fund is valued at the net asset value per share multiplied by the number of shares held as of December 31, 2011.


2.	Domestic large cap equity investments are comprised of (1) common stock, and a (2) commingled fund. Investments in common stock are valued using quoted market prices multiplied by the number of shares owned as of December 31, 2011. The investment in the commingled fund is valued at the net asset value per share multiplied by the number of shares held as of December 31, 2011.


3.	Domestic small cap equity investments are comprised of common stock and are valued using quoted market prices multiplied by the number of shares owned as of December 31, 2011.


4.	The tactical asset allocation investment is compromised of a commingled fund, which is valued at the net asset value per share multiplied by the number of shares held as of the measurement date.


5.	Fixed income securities consist of a mutual fund and corporate bonds. The investment in the mutual fund is valued using quoted market prices multiplied by the number of shares owned as of December 31, 2011. The corporate bonds are valued using various valuation techniques such as matrix pricing.


6.	As of December 31, 2011 absolute return investments consist of two partnerships. The partnerships are valued using the financial reports as of December 31, 2011.

7.	The investment consists of a money market fund, which is valued at the net asset value per share of $1.00 per unit as of December 31, 2011. The money market fund invests primarily in commercial paper, notes, repurchase agreements, and other evidences of indebtedness which are payable on demand or which have a maturity date not exceeding thirteen months from the date of purchase.

The following table sets forth by level, within the fair value hierarchy, the Other Benefits plan assets which consist of insurance benefits for retired employees, at fair value as of December 31, 2011 and 2010:

1.	This is a publicly traded balanced mutual fund. The fund seeks regular income, conservation of principal, and an opportunity for long-term growth of principal and income. The fair value is determined by taking the number of shares owned by the plan, and multiplying by the market price as of December 31, 2011.

This consists of a deposit fund and a money market fund. The fair value of the deposit fund is calculated by using the financial reports available as of December 31, 2011. The money market fund investments are valued at the net asset value per share of $1.00 per unit as of December 31, 2011. The money market fund invests primarily in commercial paper, notes, repurchase agreements, and other evidences of indebtedness which are payable on demand or which have a maturity date not exceeding thirteen months from the date or purchase.

To obtain the desired return needed to fund the pension benefit plans, the Retirement Plan Committee has established investment allocation percentages by asset classes as follows:



	Allocation

Domestic small cap equity	0	%	10	%	15	%
