Optional Living Benefits, page 21+ a. Comment -- At the beginning of this disclosure, please include the name of each of the three living benefits and state clearly that these are guaranteed minimum withdrawal features. b. Comment -- For each of the optional living benefits, please include plain English disclosure as to the purpose of the optional feature. In addition, please add disclosure to clearly distinguish each feature from the other living benefits offered under the contract. Response -- We have added the following disclosure in response to the comments above on page 21: "One of the following optional living benefits, all of which are guaranteed minimum withdrawal benefits, is available for election in your contract: MARKETLOCK INCOME PLUS offers guaranteed lifetime income plus the opportunity to lock in the greater of investment gains or an annual Income Credit for up to 5 or 10 years, even after withdrawals begin. The annual 6% Income Credit is reduced but not eliminated in any contract year in which withdrawals up to the maximum are taken, therefore providing a guarantee that income can increase even after starting withdrawals. After the first 10 years, the Income Base Evaluation Period may be extended to lock in investment gains on contract anniversaries through age 90. In addition, if no withdrawals are taken during the first 12 years, on the 12th contract anniversary, the Minimum Income Base is equal to 200% of Eligible Purchase Payments. MARKETLOCK FOR LIFE PLUS offers guaranteed lifetime income plus the opportunity to lock in the greater of investment gains or an annual Income Credit for up to 5 or 10 years, even after withdrawals begin. The annual 6% Income Credit is only available in years that no withdrawals are taken. After the first 10 years, the Income Base Evaluation Period may be extended to lock in investment gains on contract anniversaries through age 90. In addition, if no withdrawals are taken during the first 12 years, on the 12th contract anniversary, the Minimum Income Base is equal to 200% of Eligible Purchase Payments. MARKETLOCK FOR LIFE offers guaranteed lifetime income based on the contract's highest anniversary value during the contract's first 5 years. After the first 5 years, the Income Base Evaluation Period may be extended to lock in investment gains on contract anniversaries through age 90." c. Comment - Please consider additional prospectus disclosure describing the relationship between guarantees in connection with the living benefits, or other contract guarantees, and the claims paying ability of the company and its general account. Response -- The following disclosure has been added to the General Account discussion in the prospectus: "Obligations that are paid of the Company's general account ("General Account") include the interest rate on available Fixed Accounts and amounts owed under your contract for death and/or living benefits which are in excess of contract value. The General Account assets are invested in accordance with applicable state regulation. These assets are exposed to the typical risks normally associated with a portfolio of fixed income securities, namely interest rate, option, liquidity and credit risk. The Company manages its exposure to these risks by, among other things, closely monitoring and matching the duration and cash flows of its assets and liabilities, monitoring or limiting prepayment and extension risk in its portfolio, maintaining a large percentage of its portfolio in highly liquid securities and engaging in a disciplined process of underwriting, reviewing and monitoring credit risk. With respect to the living benefits available in your contract, we also manage interest and market risk through a hedging strategy in the portfolio and we require that those who elect a living benefit allocate their Purchase Payments in accordance with specified investment parameters." 4. General a. Comment -- If you intend to rely on the exemption provided by Rule 12h-7 under the Securities Exchange Act of 1934, please provide a statement to that effect in the prospectus as required by the rule. Response -- Based on established, long standing precedents and interpretations of the Federal Securities laws, the Company, as Depositor for registered separate accounts, does not believe it needs to rely on Rule 12h-7 of the Securities Exchange Act of 1934 ("34 Act") as the basis for its exemption from the duty under Section 15(d) of the 34 Act to file reports required by Section 13(a) of the 34 Act ("34 Act Reports") with respect to the variable annuities registered on this Registration Statement pursuant to the Securities Act of 1933 ("33 Act"). Should subsequent Staff interpretation or guidance with respect to Rule 12h-7 and its applicability change our analysis of this matter we will make appropriate adjustments to disclosure by supplement to the prospectus pursuant to Rule 497 of 33 Act. We will file all revisions and all relevant exhibits and financial statements in a pre-effective amendment to the registration statement on or about April 27, 2009, along with an acceleration request asking for effectiveness on April 30, 2009. As part of the acceleration request, we will also make the appropriate representations pursuant to the Staff's press release dated June 24, 2004. If you have any further questions, please contact me at 310-772-6545. Very truly yours, /s/ Manda Ghaferi Manda Ghaferi Assistant General Counsel
