At both December 31, 2011 and 2010, fixed maturity securities comprised approximately 89% of Ameriprise Financial investments.
Rating agency designations are based on the availability of ratings from Nationally Recognized Statistical Rating Organizations (‘‘NRSROs’’), including Moody’s Investors Service (‘‘Moody’s’’), Standard & Poor’s Ratings Services (‘‘S&P’’) and Fitch Ratings Ltd.  (‘‘Fitch’’).
The Company uses the median of available ratings from Moody’s, S&P and Fitch, or, if fewer than three ratings are available, the lower rating is used.
When ratings from Moody’s, S&P and Fitch are unavailable, the Company may utilize ratings from other NRSROs or rate the securities internally.
At both December 31, 2011 and 2010, the Company’s internal analysts rated $1.2 billion of securities, using criteria similar to those used by NRSROs.
A summary of fixed maturity securities by rating was as follows:

The following tables provide information about Available-for-Sale securities with gross unrealized losses and the length of time that individual securities have been in a continuous unrealized loss position:
## Table 1 ##
## Table 2 ##
As part of Ameriprise Financial’s ongoing monitoring process, management determined that a majority of the gross unrealized losses on its Available-for-Sale securities are attributable to movement in credit spreads.

Employee Plans The Company established an Employee Share Purchase Plan to provide each employee and trustee the ability to annually acquire up to $100,000 of Common Shares of the Company.
In 2003, the Company’s shareholders approved an increase in the aggregate number of Common Shares available under the ESPP to 7,000,000 (from 2,000,000).
The Company has 3,403,970 Common Shares available for purchase under the ESPP at December 31, 2010.
The Common Shares may be purchased quarterly at a price equal to 85% of the lesser of: (a) the closing price for a share on the last day of such quarter; and (b) the greater of: (i) the closing price for a share on the first day of such quarter, and (ii) the average closing price for a share for all the business days in the quarter.
The following table summarizes information regarding the Common Shares issued under the ESPP:
## Table 3 ##
The Company established a defined contribution plan (the “401(k) Plan”) to provide retirement benefits for employees that meet minimum employment criteria.
The Company matches dollar for dollar up to the first 3% of eligible compensation that a participant contributes to the 401(k) Plan.
Participants are vested in the Company’s contributions over five years.
The Company recognized an expense in the amount of $4.0 million, $3.5 million and $3.8 million for the years ended December 31, 2010, 2009 and 2008, respectively.
The Company may also elect to make an annual discretionary profit-sharing contribution as a percentage of each individual employee’s eligible compensation under the 401(k) Plan.
The Company did not make a contribution for the years ended December 31, 2010, 2009 and 2008 and as such, no expense was recognized in these years.
The Company established a supplemental executive retirement plan (the “SERP”) to provide certain officers and trustees an opportunity to defer a portion of their eligible compensation in order to save for retirement.
The SERP is restricted to investments in Company Common Shares, certain marketable securities that have been specifically approved and cash equivalents.
The deferred compensation liability represented in the SERP and the securities issued to fund such deferred compensation liability are consolidated by the Company and carried on the Company’s balance sheet, and the Company’s Common Shares held in the SERP are accounted for as a reduction to paid in capital.16.
Distribution Reinvestment and Share Purchase Plan On November 3, 1997, the Company filed with the SEC a Form S-3 Registration Statement to register 14,000,000 Common Shares pursuant to a Distribution Reinvestment and Share Purchase Plan (the “DRIP Plan”).
The registration statement was declared effective on November 25, 1997.
The remaining shares available for issuance under the 1997 registration lapsed in December 2008.
On December 16, 2008, the Company filed with the SEC a Form S-3 Registration Statement to register 5,000,000 Common Shares under the DRIP Plan.
The registration statement was automatically declared effective the same day and expires at the earlier of the date in which all 5,000,000 shares have been issued or December 15, 2011.
The Company has 4,905,736 Common Shares available for issuance under the DRIP Plan at December 31, 2010.
The DRIP Plan provides holders of record and beneficial owners of Common Shares and Preferred Shares with a simple and convenient method of investing cash distributions in additional Common Shares (which is referred to herein as the “Dividend Reinvestment – DRIP Plan”).
Common Shares may also be purchased on a monthly basis with optional cash payments made by participants in the DRIP Plan and interested new investors, not currently shareholders of the Company, at the market price of the Common Shares less a discount ranging between 0% and 5%, as determined in accordance with the DRIP Plan (which is referred to herein as the “Share Purchase – DRIP Plan”).
Common Shares purchased under the DRIP Plan may, at the option of the Company, be directly issued by the Company or purchased by the Company’s transfer agent in the open market using participants’ funds.
remaining service period of active members expected to receive benefits under the plan or, in the case of closed plans, the expected future lifetime of the employees participating in the plan.
For the years ended December 31, 2018 and 2017, the service cost component of net periodic benefit cost was classified in Selling, general and administrative expenses, while the other components of net periodic benefit cost were classified in Other income, net in our Consolidated Statements of Income.
For the year ended December 31, 2016, all components of net periodic benefit expense were included in Selling, general, and administrative expenses in our Consolidated Statements of Income.
For the year ending December 31, 2019, we expect net periodic benefit costs to increase by approximately $2 million due to the fact that we will incur a full year of pension expense related to our Stahlgruber business, compared to a partial year in 2018.
The table below summarizes the weighted-average assumptions used to calculate the net periodic benefit cost in the table above:
