UNITED STATES SECURITIES AND EXCHANGE COMMISSION Washington, D.C. 20549 FORM N-CSR CERTIFIED SHAREHOLDER REPORT OF REGISTERED MANAGEMENT INVESTMENT COMPANIES Investment Company Act file number: 811-21622 Thrivent Financial Securities Lending Trust (Exact name of registrant as specified in charter) 625 Fourth Avenue South Minneapolis, Minnesota 55415 (Address of principal executive offices) (Zip code) John C. Bjork, Assistant Secretary 625 Fourth Avenue South Minneapolis, Minnesota 55415 (Name and address of agent for service) Registrant's telephone number, including area code: (612) 340-7005 Date of fiscal year end: October 31 Date of reporting period: April 29, 2005 Item 1. Report to Stockholders - ------------------------------ SEMIANNUAL REPORT APRIL 29, 2005 THRIVENT FINANCIAL SECURITIES LENDING TRUST THRIVENT FINANCIAL SECURITIES LENDING TRUST William D. Stouten, Portfolio Manager The Trust seeks to maximize current income to the extent consistent with the preservation of capital and liquidity; and maintain a stable $1.00 per share net asset value by investing in dollar-denominated securities with remaining maturity of one year or less. During the six-month period ended April 29, 2005, the Federal Open Market Committee continued its tightening pattern of raising the fed funds rate. While the Trust's weighted-average maturity has fluctuated in response to these moves, it remained shorter than the weighted-average maturity of the peer group throughout the period. We expect the Fed to continue to raise rates at a measured pace, and we will continue to manage for liquidity and conservative yield improvement.

Effective yields reflect the reinvestment of income. Yields are subject to daily fluctuation and should not be considered an indication of future results. ** Past performance is not an indication of future results. Investing in a mutual fund involves risks, including the possible loss of principal. The prospectus contains more complete information on the investment objectives, risks, charges and expenses of the investment company which investors should read and consider carefully before investing. Annualized total returns represent past performance and reflect changes in share prices, the reinvestment of all dividends and capital gains, and the effects of compounding. The returns shown do not reflect taxes a shareholder would pay on distributions or redemptions. Shareholder Expense Example (Unaudited) As a shareholder of the Trust, you incur ongoing cost, including management fees and other Trust expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Trust and to compare these costs with the ongoing costs of investing in other mutual funds. The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period from November 1, 2004 through April 29, 2005. Actual Expenses The first line of the table below provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during the period. Hypothetical Example for Comparison Purposes The second line of the table below provides information about hypothetical account values and hypothetical expenses based on the Trust's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Trust's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Trust and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical example that appears in the shareholder reports of the other funds. Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads), redemption fees, or exchange fees. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

NOTES TO FINANCIAL STATEMENTS AS OF APRIL 29, 2005 (UNAUDITED) Thrivent Financial Securities Lending Trust A. Organization The Thrivent Financial Securities Lending Trust (the "Trust") was organized as a Massachusetts Business Trust on August 5, 2004 and is registered as an open-end management investment company under the Investment Company Act of 1940. The Trust commenced operations on September 16, 2004. All transactions in the Trust are from Affiliates of the Trust. Under the Trust's organizational documents, its officers and trustees are indemnified against certain liabilities arising out of the performance of their duties to the Trust. In addition, in the normal course of business, the Trust enters into contracts with vendors and others that provide general damage clauses. The Trust's maximum exposure under these contracts is unknown, as this would involve future claims that may be made against the Trust. However, based on experience, the Trust expects the risk of loss to be remote. B. Significant Accounting Policies Valuation - Securities are valued on the basis of amortized cost (which approximates value), whereby a portfolio security is valued at its cost initially, and thereafter valued to reflect a constant amortization to maturity of any discount or premium. Federal Income Taxes - The Trust intends to comply with the requirements of the Internal Revenue Code which are applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. The Trust, accordingly, anticipates paying no Federal income taxes and no Federal income tax provision was required. Fees Paid Indirectly - The Trust has a deposit arrangement with the custodian whereby interest earned on uninvested cash balances is used to pay a portion of custodian fees. This deposit arrangement is an alternative to overnight investments. Distributions to Shareholders - Net investment income is distributed to each shareholder as a dividend. Dividends from the Trust are declared daily and distributed monthly. Net realized gains from securities transactions, if any, are distributed at least annually in the calendar year. Use of Estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America require management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from these estimates. Other - For financial statement purposes, investment security transactions are accounted for on the trade date. Interest income is recognized on an accrual basis. Discount and premium are amortized over the life of the respective securities on the interest method. Realized gains or losses on sales are determined on a specific cost identification basis. C. Investment Advisory Management Fees and Transactions with Related Parties The Trust has entered into an Investment Advisory Agreement with Thrivent Financial for Lutherans (the "Adviser") under which the Trust pays a fee for investment advisory services. The annual rate of fees under the Investment Advisory Agreement are calculated at 0.045% of the average daily net assets of the Trust. Each Trustee who is not affiliated with Thrivent Financial for Lutherans or the Adviser receives an annual fee from the Trust for services as a Trustee and is eligible to participate in a deferred compensation plan with respect to these fees. Each participant's deferred compensation account will increase or decrease as if it were invested in shares of the Thrivent Mutual Funds based on their choice. Trustees not participating in the above plan received $2,571 in fees from the Trust for the six months ended April 29, 2005. No remuneration has been paid by the Trust to any of the officers or affiliated Trustees of the Trust. In addition, the Trust reimbursed certain reasonable expenses incurred in relation to attendance at the meetings. The Adviser has voluntarily reimbursed the Trust for all expenses in excess of 0.05% of average daily net assets since inception. D. Federal Income Tax Information The cost basis of the investments is the same for financial reporting purposes and Federal income tax purposes. E. Trust Transactions Transactions in trust shares were as follows: Shares Amount Period from September 16, 2004 to October 31, 2004 Sold 4,630,139,403 $4,630,139,403 Redeemed (687,797,704) (687,797,704) ------------- -------------- Net Change 3,942,341,699 $3,942,341,699 ============= ============== For the Six Months Ended April 29, 2005 Sold 6,385,178,628 $6,385,178,628 Redeemed (6,420,394,847) (6,420,394,847) ------------- -------------- Net Change (35,216,219) $(35,216,219) ============= ============== FINANCIAL HIGHLIGHTS PER SHARE INFORMATION (a) Thrivent Financial Securities Lending Trust For the Six Period From Months Ended 9/16/2004 4/29/2005 (inception) (unaudited) To 10/31/2004 - ------------------------------------------------------------------- Net asset value: Beginning of Period $1.00 $1.00 Income from Investment Operations: Net investment income 0.01 0.00 Net realized and unrealized gain/(loss) on investments (b) -- -- - ------------------------------------------------------------------- Total from Investment Operations 0.01 0.00 =================================================================== Distributions from: Net investment income (0.01) 0.00 - ------------------------------------------------------------------- Total Distributions (0.01) 0.00 =================================================================== Net asset value: End of Period $1.00 $1.00 =================================================================== Total return (c) 1.17% 0.22% Net assets: end of period (in thousands) $3,907.1 $3,942.3 Ratio of expenses to average net assets (d) 0.05% 0.05% Ratio of net investment income to average net assets (d) 2.38% 1.80% Portfolio turnover rate N/A N/A If the Fund had paid all its expenses without the advisors voluntary expense reimbursement, the ratios would have been as follows: Ratio of expenses to average net assets (d) 0.05% 0.05% Ratio of net investment income to average net assets (d) 2.37% 1.80% (a) All per share amounts have been rounded to the nearest cent.
