REPORTS TO UNITHOLDERS. Iowa Public Agency Investment Trust www.IPAIT.org Semi-Annual Financial Report Diversified Fund Direct Government Obligation Fund December 31, 2006 Sponsored by the Iowa Association of Municipal Utilities Iowa State Association of Counties Iowa League of Cities Trustees' Report To Iowa Public Agency Investment Trust Participants: The Iowa Public Agency Investment Trust (IPAIT) is pleased to present this semi-annual report of IPAIT operations for the six-month period ended December 31, 2006. For the first time in 3 1/2 years, the Federal Reserve kept its overnight rate constant for six consecutive months. The Federal Reserve's last move occurred on June 29, and has since kept the base rate at 5.25 percent. This constant level led to relatively consistent IPAIT fund yields with the Diversified Fund offering a 7-day yield of 4.537 percent on June 30, and 4.757 percent on December 31. The Direct Government Obligation Fund offered 4.349 and 4.524 percent during the same time period. It is anticipated that short-term interest rates will remain constant the first half of 2007. While the portfolio was constructed to take advantage of Federal Reserve rate increases in 2006, it is now being managed to produce competitive yields in a more challenging, flat interest rate environment. We encourage you to visit the website, www.IPAIT.org, to compare IPAIT yields to those provided by your financial institution. The IPAIT Fixed-Term Automated (FTA) program saw excellent activity. In the last six months of 2006, IPAIT solicited 429 competitive bids on behalf of participants, up from 310 in the same period last year. The FTA program ended the year at a 2-year high, helped in large part by one of the biggest Flexible Withdrawal Certificates (Flex-CD's) in program history, $50.3 million. While the IPAIT FTA program did not always provide the highest bid, utilizing the program helped insure many local public entities received a more competitive rate, the principle on which IPAIT was founded. In October, the Board of Trustees approved new service contracts with WB Capital and Wells Fargo effective January 1, 2007. The new contracts reflect a 25 percent fee decrease, and include participation by all IPAIT service providers and sponsors. This new fee structure will allow IPAIT to be more competitive, and places total program fees well within the lower half of comparable association-sponsored programs in the country. We appreciate this commitment made by the service providers and program sponsors. The Board of Trustees is very pleased with the ongoing success of the IPAIT program and the benefits it provides. As always, we welcome any comments or suggestions that you may have. Sincerely, /s/ Tom Hanafan Tom Hanafan, ChairBoard of Trustees 1 Management Report To Iowa Public Agency Investment Trust Participants: Since pausing in June, the Federal Reserve has expressed concern that inflation pressures will increase even as economic growth is slowing. While recent Federal Reserve meeting minutes reflect similar concerns, there is growing acknowledgment that the inflation picture is improving. Declines in housing activity have yet to affect consumer spending, which increases the probability of continued economic expansion and thus range-bound interest rates. Overnight rates remain at 5.25 percent, but market expectations for a near-term rate cut have decreased. Although core inflation numbers have come off their highs, they remain above Federal Reserve targets and will keep the Federal Reserve's attention. The money market yield curve has flattened substantially over the past year and will not likely change much until the Federal Reserve's next move becomes clearer. Now that the Federal Reserve is on hold, there is less incentive to remain in short maturity positions. As market opportunities arise we will invest in some longer maturity assets to maintain an optimal yield. We appreciate your confidence in the IPAIT program and we work hard to preserve that trust. Thank you for allowing us to serve you by providing good yield within an investing framework that emphasizes the important tenets of safety and liquidity. Here is to a prosperous 2007. Sincerely, /s/ Jeffrey D. Lorenzen Jeffrey D. Lorenzen, CFAChief Investment OfficerWB Capital Management Inc. 2 Management's Discussion & Analysis This section of the IPAIT Diversified Portfolio's semi-annual financial report presents management's discussion and analysis of the financial position and results of operations during the six-month periods ended December 31, 2006 and December 31, 2005. This information is being presented to provide additional information regarding the activities of IPAIT, pursuant to the requirements of Governmental Accounting Standards Board Statement No. 34, Basic Financial Statements - and Management's Discussion and Analysis - for State and Local Governments, Statement No. 37, Basic Financial Statements - and Management's Discussion and Analysis - for State and Local Governments: Omnibus, and Statement No. 38, Certain Financial Statement Note Disclosures (Statements Nos. 34, 37, and 38). This discussion and analysis should be read in conjunction with the Financial Statements and the accompanying notes. Overview of the Financial Statements The Management's Discussion and Analysis provides an introduction to and overview of the basic financial statements of IPAIT's Diversified Portfolio. The following components comprise the basic financial statements: 1) Schedule of Investments, 2) Statement of Net Assets, 3) Statements of Operations, 4) Statements of Changes in Net Assets, and 5) Notes to Financial Statements. o The Schedule of Investments lists each security held by the portfolio as of December 31. o The Statement of Net Assets shows the financial position (assets and liabilities) of the portfolio as of December 31. o The Statements of Operations display the results of operations (income and expenses) of the portfolio for the six-month periods ended December 31, 2006 and December 31, 2005. o The Statements of Changes in Net Assets display the results of additions (net investment income, unit sales, and reinvestments) and deductions (dividends and unit redemptions) of the portfolio for the six-month periods ended December 31, 2006 and December 31, 2005. o The Notes to Financial Statements describe significant accounting policies and disclose summary security transaction amounts of the portfolio. Condensed Financial Information and Financial Analysis Year-over-year changes in most financial statement amounts reported in IPAIT's Diversified Portfolio are most significantly impacted by the level of average net assets (which fluctuates based on the overall levels of participant/unitholder invested balances). Additionally, changes in the short-term interest rate environment (which follows the general trend established by monetary policy set by the Federal Reserve) contribute to year-over-year variances in the amount of investment income earned by the portfolio. Over the last six months, the Federal Reserve's Federal Open Market Committee has not changed the Federal Funds target rate. In the preceding twelve months, the Federal Funds target rate was increased eight times, from 3.25 percent to 5.25 percent. Condensed financial information and changes explanations for the six-month period ended December 31, 2006, as compared to the same period ended December 31, 2005 follows. December 31, Percent December 31, 2006 Change 2005 Net Assets ------------- ------ ------------ Total Investments $245,236,083 1% $242,882,755 Excess of total liabilities over other assets (77,806) 68% (246,615) ------------- ------------ Net assets held in trust for pool participants $245,158,277 1% $242,636,140 ============= ============ 3 Management's Discussion & Analysis (continued) Diversified Portfolio Total investments and net assets as of December 31, 2006 increased 1 and 1 percent, respectively, compared to December 31, 2005. During the six-month period ended December 31, 2006, average net assets increased 1 percent to $234,560,807 from average net assets of $233,119,144 during the same period in the prior year.

With the increase in Fed Fund rates, money market fund returns improved during 2006. Total expenses are derived based on net assets held by the Fund. These expenses decreased 1 percent during the six-month period ended December 31, 2006 compared to the same period in the prior year due to a reduction in the investment adviser and administration fees effective November 1, 2005. During the six-month period ended December 31, 2006 compared to the same period in the prior year, units sold and redeemed increased 10 percent and 5 percent, respectively. 4 Management's Discussion & Analysis (continued) Condensed financial information and changes explanations for the six-month period ended December 31, 2005, as compared to the same period ended December 31, 2004 follows. December 31, Percent December 31, 2005 Change 2004 Net Assets ------------- ------ ------------ Total Investments $242,882,755 10% $221,088,413 Excess of total liabilities over other assets (246,615) -150% 493,757 ------------- ------------ Net assets held in trust for pool participants $242,636,140 10% $221,582,170 ============= ============ Diversified Portfolio Total investments and net assets as of December 31, 2005 increased 10 percent and 10 percent, respectively, compared to December 31, 2004, due to an increase in aggregate participant balances. During the six-month period ended December 31, 2005, average net assets increased 9 percent compared to the average net assets for the same period in the prior year.

Total expenses are derived based on net assets held by the Fund. Total expenses increased 12 percent during the six-month period ended December 31, 2005 compared to same period in 2004 due to an increase in average net assets. Units sold and redeemed increased 9 percent and 1 percent, respectively, caused by an increase in participant gross inflows and outflows during the six-month period ending December 31, 2005 compared to the same period in 2004.

IPAIT is registered under the Investment Company Act of 1940 as required by Iowa Statute and files reports with the Securities and Exchange Commission under Regulation S-X. IPAIT was established by the adoption of a Joint Powers Agreement and Declaration of Trust as of October 1, 1987, and commenced operations on November 13, 1987. The Joint Powers Agreement and Declaration of Trust was amended September 1, 1988, May 1, 1993, and again on September 1, 2005. As amended, IPAIT is authorized to operate and now operates investment programs, one of which is the Diversified Portfolio. The accompanying financial statements include activities of the Diversified Portfolio. The objective of the portfolio is to maintain a high degree of liquidity and safety of principal through investment in short-term securities as permitted for Iowa public agencies under Iowa law. Wells Fargo Bank, N.A. (Wells Fargo), serves as the Custodian, and WB Capital Management Inc. (WB Capital) serves as the Investment Adviser, Administrator, and Program Support Provider. The preparation of financial statements, in conformity with U.S. generally accepted accounting principles, requires 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 net investment income during the year. Actual results could differ from those estimates. In reporting financial activity, IPAIT applies applicable Governmental Accounting Standards Board (GASB) pronouncements, as well as all Financial Accounting Standards Board and predecessor statements and interpretations not in conflict with GASB pronouncements. IPAIT is exposed to various risks in connection with operation of the Diversified Portfolio and adheres to policies which mitigate market risk in the portfolio and maintains insurance coverage for fidelity and errors and omissions exposures. IPAIT has had no claims or settlements under its insurance coverage since its organization in 1987. Investments in Securities The Diversified Portfolio consists of cash and short-term investments valued at amortized cost, which approximates fair value, pursuant to Rule 2a-7 under the Investment Company Act of 1940. This involves valuing a portfolio security at its original cost on the date of purchase, and thereafter amortizing any premium or discount on a straight-line basis to maturity. The amount of premium or discount amortized to income under the straight-line method does not differ materially from the amount which would be amortized to income under the interest method. Procedures are followed to maintain a constant net asset value of $1.00 per unit for the portfolio. Security transactions are accounted for on the trade date. Interest income, including the accretion of discount and amortization of premium, is recorded daily on an accrual basis. IPAIT is authorized by investment policy and statute to invest public funds in obligations of the U.S. government, its agencies and instrumentalities; certificates of deposit and other evidences of deposit at 10 Iowa Public Agency Investment Trust Diversified Portfolio Notes to Financial Statements (unaudited) (continued) federally insured Iowa depository institutions approved and secured pursuant to Chapter 12 of the Code of Iowa; and repurchase agreements, provided that the underlying collateral consists of obligations of the U.S. government, its agencies and instrumentalities and that IPAIT's custodian takes delivery of the collateral either directly or through an authorized custodian. In connection with transactions in repurchase agreements, it is IPAIT's policy that its custodian take possession of the underlying collateral securities, the value of which exceeds the principal amount of the repurchase transaction, including accrued interest at all times. If the seller defaults and the value of the collateral declines, realization of the collateral by IPAIT may be delayed or limited. At December 31, 2006 and December 31, 2005, the securities purchased under overnight agreements to resell were collateralized by government agency securities with a value of $172,010,789 and $166,820,199, respectively. Certificate of deposit amounts up to $100,000 are insured by the Federal Depository Insurance Company (FDIC). For public funds deposited in Iowa financial institutions in excess of the $100,000 FDIC insurance, the local financial institution must comply with Iowa Code Section 12c.22 to insure appropriate collateralization. As of December 31, 2006, public funds invested in certificates of deposit not covered by FDIC insurance were $12,800,000. Public funds not covered by FDIC or collateralization are covered by the state sinking fund in accordance with Chapter 12C of the Code of Iowa, which provides for additional assessments against depositories to ensure there will be no loss of public funds. Under Governmental Accounting Standards as to custodial credit risk, IPAIT's investments in securities are classified as Category One. Category One consists of insured or registered securities or securities held by IPAIT or its agent in IPAIT's name and is the most secure investment category description. As of December 31, 2006, the Diversified Portfolio security credit ratings were 23.7 percent AAA, 5.7 percent not rated (representing all Certificates of Deposit from Iowa financial institutions), and 70.6 percent NA. Securities which carry an NA rating are government securities which are deemed to carry the equivalent of A1+/P1 ratings by the IPAIT Board of Trustees. IPAIT's exposure to interest rate risk is mitigated by the fact that securities are limited under Rule 2a-7 as well as by investment policy and statute to investments of high quality with durations not to exceed 397 days. Hence any significant change in market interest rates would not present long term risk to IPAIT. Unit Issues, Redemptions and Distributions IPAIT determines the net asset value of the Diversified Portfolio daily. Units are issued and redeemed daily at the daily net asset value. Dividends from net investment income are declared daily and distributed monthly.

This information is being presented to provide additional information regarding the activities of IPAIT, pursuant to the requirements of Governmental Accounting Standards Board Statement No. 34, Basic Financial Statements - and Management's Discussion and Analysis - for State and Local Governments, Statement No. 37, Basic Financial Statements - and Management's Discussion and Analysis - for State and Local Governments: Omnibus, and Statement No. 38, Certain Financial Statement Note Disclosures (Statements Nos. 34, 37, and 38). This discussion and analysis should be read in conjunction with the Financial Statements and the accompanying notes. Overview of the Financial Statements The Management's Discussion and Analysis provides an introduction to and overview of the basic financial statements of IPAIT's Direct Government Obligation Portfolio. The following components comprise the basic financial statements: 1) Schedule of Investments, 2) Statement of Net Assets, 3) Statements of Operations, 4) Statements of Changes in Net Assets, and 5) Notes to Financial Statements. o The Schedule of Investments lists each security held by the portfolio as of December 31. o The Statement of Net Assets shows the financial position (assets and liabilities) of the portfolio as of December 31. o The Statements of Operations display the results of operations (income and expenses) of the portfolio for the six-month periods ended December 31, 2006 and December 31, 2005. o The Statements of Changes in Net Assets display the results of additions (net investment income, unit sales, and reinvestments) and deductions (dividends and unit redemptions) of the portfolio for the six-month periods ended December 31, 2006 and December 31, 2005. o The Notes to Financial Statements describe significant accounting policies and disclose summary security transaction amounts of the portfolio. Condensed Financial Information and Financial Analysis Year-over-year changes in most financial statement amounts reported in IPAIT's Direct Government Obligation Portfolio are most significantly impacted by the level of average net assets (which fluctuates based on the overall levels of participant/unitholder invested balances). Additionally, changes in the short-term interest rate environment (which follows the general trend established by monetary policy set by the Federal Reserve) contribute to year-over-year variances in the amount of investment income earned by the portfolio. Over the last six months, the Federal Reserve's Federal Open Market Committee has not changed the Federal Funds target rate. In the preceding twelve months, the Federal Funds target rate was increased eight times, from 3.25 percent to 5.25 percent. 14 Management's Discussion & Analysis (continued) Condensed financial information and changes explanations for the six-month period ended December 31, 2006, as compared to the same period ended December 31, 2005 follows. December 31, Percent December 31, 2006 Change 2005 Net Assets ------------- ------ ------------ Total Investments $21,880,888 65% $13,295,032 Excess of total liabilities over other assets (7,230) 75% (28,851) ------------- ------------ Net assets held in trust for pool participants $21,873,658 65% $13,266,181 ============= ============ Direct Government Obligation Portfolio Total investments and net assets as of December 31, 2006 increased 65 and 65 percent, respectively, compared to December 31, 2005. During the six-month period ended December 31, 2006, average net assets increased 39 percent to $20,834,458 from average net assets of $14,973,492 during the same period in the prior year. The DGO portfolio experienced a net purchase of assets in this six-month period partially due to the transfer of assets from the Diversified portfolio. December 31, Percent December 31, Change in Net Asset for the periods ended 2006 Change 2005 ------------- ------ ------------ Investment Income $540,108 101% $268,568 Total Expenses (53,039) 37% (38,612) Dividends to unitholders from net investment income (487,069) 112% (229,956) Net increase (decrease) in assets derived from unit transactions 4,924,503 422% (1,529,502) Net assets held in trust for pool participants at beginning of period 16,949,155 15% 14,795,683 -------------- ------------- Net assets held in trust for pool participants at end of period $21,873,658 65% $13,266,181 ============== ============= Investment income and net investment income increased 101 percent and 112 percent, respectively, during the six-month period ended December 31, 2006 compared to the same period in the prior year due to the higher interest rate environment and higher average net assets. With the increase in Fed Fund rates, money market fund returns have improved during 2006. Total expenses are derived based on net assets held by the Fund. These expenses increased 37 percent during the six-month period ended December 31, 2006 compared to the same period in the prior year due to an increase in average net assets. During the six-month period ended December 31, 2006 compared to the same period in the prior year, units sold and redeemed decreased 14 percent and 42 percent, respectively. 15 Management's Discussion & Analysis (continued) Condensed financial information and changes explanations for the six-month period ended December 31, 2005, as compared to the same period ended December 31, 2004 follows. December 31, Percent December 31, 2005 Change 2004 Net Assets ------------- ------ ------------ Total Investments $13,295,032 -40% $22,131,039 Excess of total liabilities over other assets (28,851) -211% 25,983 ------------- ------------ Net assets held in trust for pool participants $13,266,181 -40% $22,157,021 ============= ============ Direct Government Obligation Portfolio Total investments and net assets as of December 31, 2005 declined 40 percent and 40 percent, respectively, compared to December 31, 2004, due to lower aggregate participant balances. During the six-month period ended December 31, 2005, average net assets decreased 52 percent compared to the average net assets for the same period in the prior year. December 31, Percent December 31, Change in Net Asset for the periods ended 2005 Change 2004 ------------- ------ ------------ Investment Income $268,568 12% $238,792 Total Expenses (38,612) -50% (76,724) Dividends to unitholders from net investment income (229,956) 42% (162,068) Net increase (decrease) in assets derived from unit transactions (1,529,502) 90% (15,375,227) Net assets held in trust for pool participants at beginning of period 14,795,683 -61% 37,532,248 ------------- ------------- Net assets held in trust for pool participants at end of period $13,266,181 -40% $22,157,021 ============= ============= Investment income and net investment income increased 12 percent and 42 percent, respectively, during the six-month period ended December 31, 2005 compared to the same period in 2004 primarily due to realizing a higher rate of return on assets and lower average net assets resulting in a decrease to expenses. Total expenses are derived based on net assets held by the Fund. Total expenses decreased 50 percent during the six-month period ended December 31, 2005 compared to same period in 2004 due to lower average net assets. Units sold increased 135 percent, caused by an increase in participant gross inflows during the six-month period December 31, 2005 compared to the same period in 2004. Units redeemed decreased 12 percent during the six-month period ended December 31, 2005 compared to the same period in the prior year.

IPAIT is registered under the Investment Company Act of 1940 as required by Iowa Statute and files reports with the Securities and Exchange Commission under Regulation S-X. IPAIT was established by the adoption of a Joint Powers Agreement and Declaration of Trust as of October 1, 1987, and commenced operations on November 13, 1987. The Joint Powers Agreement and Declaration of Trust was amended September 1, 1988, May 1, 1993, and again on September 1, 2005. As amended, IPAIT is authorized to operate and now operates investment programs, one of which is the Direct Government Obligation Portfolio. The accompanying financial statements include activities of the Direct Government Obligation Portfolio. The objective of the portfolio is to maintain a high degree of liquidity and safety of principal through investment in short-term securities as permitted for Iowa public agencies under Iowa law. Wells Fargo Bank, N.A. (Wells Fargo), serves as the Custodian, and WB Capital Management Inc. (WB Capital) serves as the Investment Adviser, Administrator, and Program Support Provider. The preparation of financial statements, in conformity with U.S. generally accepted accounting principles, requires 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 net investment income during the year. Actual results could differ from those estimates. In reporting financial activity, IPAIT applies applicable Governmental Accounting Standards Board (GASB) pronouncements, as well as all Financial Accounting Standards Board and predecessor statements and interpretations not in conflict with GASB pronouncements. IPAIT is exposed to various risks in connection with operation of the Direct Government Obligation Portfolio and adheres to policies which mitigate market risk in the portfolio and maintains insurance coverage for fidelity and errors and omissions exposures. IPAIT has had no claims or settlements under its insurance coverage since its organization in 1987. Investments in Securities The Direct Government Obligation Portfolio consists of cash and short-term investments valued at amortized cost, which approximates fair value, pursuant to Rule 2a-7 under the Investment Company Act of 1940. This involves valuing a portfolio security at its original cost on the date of purchase, and thereafter amortizing any premium or discount on a straight-line basis to maturity. The amount of premium or discount amortized to income under the straight-line method does not differ materially from the amount which would be amortized to income under the interest method. Procedures are followed to maintain a constant net asset value of $1.00 per unit for the portfolio. Security transactions are accounted for on the trade date. Interest income, including the accretion of discount and amortization of premium, is recorded daily on an accrual basis. 21 Iowa Public Agency Investment Trust Direct Government Obligation Portfolio Notes to Financial Statements (unaudited) (continued) IPAIT is authorized by investment policy and statute to invest public funds in obligations of the U.S. government, its agencies and instrumentalities; and repurchase agreements, provided that the underlying collateral consists of obligations of the U.S. government, its agencies and instrumentalities and that IPAIT's custodian takes delivery of the collateral either directly or through an authorized custodian. In connection with transactions in repurchase agreements, it is IPAIT's policy that its custodian take possession of the underlying collateral securities, the value of which exceeds the principal amount of the repurchase transaction, including accrued interest at all times. If the seller defaults and the value of the collateral declines, realization of the collateral by IPAIT may be delayed or limited. At December 31, 2006 and December 31, 2005, the securities purchased under overnight agreements to resell were collateralized by government agency securities with a value of $15,025,910 and $7,521,300, respectively. Under Governmental Accounting Standards as to custodial credit risk, IPAIT's investments in securities are classified as Category One. Category One consists of insured or registered securities or securities held by IPAIT or its agent in IPAIT's name and is the most secure investment category description. As of December 31, 2006, the Direct Government Obligation Portfolio security credit ratings were 32.5 percent AAA, and 67.5 percent NA. Securities which carry an NA rating are government securities which are deemed to carry the equivalent of A1+/P1 ratings by the IPAIT Board of Trustees. IPAIT's exposure to interest rate risk is mitigated by the fact that securities are limited under Rule 2a-7 as well as by investment policy and statute to investments of high quality with durations not to exceed 397 days. Hence any significant change in market interest rates would not present long term risk to IPAIT. Unit Issues, Redemptions and Distributions IPAIT determines the net asset value of the Direct Government Obligation Portfolio daily. Units are issued and redeemed daily at the daily net asset value. Dividends from net investment income are declared daily and distributed monthly. Income Taxes IPAIT is exempt from both state and federal income taxes pursuant to Section 115 of the Internal Revenue Code. Fees and Expenses Under separate agreements with IPAIT, WB Capital and Wells Fargo are paid an annual fee for operating the investment program. 22 Iowa Public Agency Investment Trust Direct Government Obligation Portfolio Notes to Financial Statements (unaudited) (continued) During the period of July 1, 2006 to December 31, 2006, WB Capital received 0.250 percent of the average daily net asset value up to $100 million, 0.215 percent from $100 to $250 million and 0.170 percent exceeding $250 million for investment adviser and administrative fees. In addition, WB Capital received 0.080 percent of the average daily net asset value for program support fees. For the six-month periods ended December 31, 2006 and 2005, the DGO Portfolio paid $34,659 and $25,403, respectively, to WB Capital for services provided. Wells Fargo received 0.050 percent of the average daily net asset value up to $150 million, 0.045 percent from $150 to $300 million, and 0.040 percent exceeding $300 million for custodial services. For the six-month periods ended December 31, 2006 and 2005, the DGO Portfolio paid $5,251 and $3,774, respectively, to Wells Fargo for services provided. Under a distribution plan the public agency associations collectively received an annual fee of 0.100 percent of the daily net asset value of the portfolio. For the six-month periods ended December 31, 2006 and 2005, the DGO Portfolio paid $10,503 and $7,548 to the Iowa League of Cities, respectively. IPAIT is responsible for other fees and expenses incurred directly by IPAIT. The other fees and expenses accrual is 0.025 percent on the average daily net asset value, and amounted to $2,626 and $1,887, for the six-month periods ended December 31, 2006 and December 31, 2005, respectively. All fees are computed daily and paid monthly. (2) SECURITIES TRANSACTIONS Purchases of portfolio securities for the DGO Portfolio aggregated $1,739,158,835 and $1,156,777,000, for the six-month periods ended December 31, 2006 and December 31, 2005, respectively. Proceeds from maturities of securities for the DGO Portfolio aggregated $1,735,485,000 and $1,158,273,000 for the six-month periods ended December 31, 2006 and December 31, 2005, respectively.

All mutual funds have operating expenses. As a shareholder of the fund, you incur ongoing costs, including management fees, distribution and service fees, and other fund expenses. Expenses, which are deducted from a fund's investment income, directly reduce the investment return of the fund. A fund's expenses are expressed as a percentage of its average net assets. This figure is known as the expense ratio. The following examples are intended to help you understand the ongoing costs (in dollars) of investing in your fund and compare these costs with those of other mutual funds. The examples are based on an investment of $1,000 made at the beginning of the period and held for the entire period from July 1, 2006 to December 31, 2006. The table illustrates your fund's costs in two ways: 1. Based on actual fund return. This section helps you to estimate the actual expenses that you paid over the period. The "Ending Account Value" shown is derived from the fund's actual return, and the third column shows the dollar amount that would have been paid by an investor who started with $1,000 in the fund. You may use the information here, together with the amount you invested, to estimate the expenses that you paid over the period. 2. Based on hypothetical 5 percent return. This section is intended to help you compare your fund's costs with those of other mutual funds. It assumes that the fund had a return of 5 percent before expenses during the period shown, but that the expense ratio is unchanged. In this case, because the return used is not the fund's actual return, the results do not apply to your investment. The example is useful in making comparisons because the Securities and Exchange Commission requires all mutual funds to calculate expenses based on a 5 percent return. You can assess your fund's costs by comparing this hypothetical example with the hypothetical examples that appear in shareholder reports of other funds. Your fund does not carry a "sales load" or transaction fee. The calculations assume no shares were bought or sold during the period. Your actual costs may have been higher or lower, depending on the amount of your investment and timing of any purchases or redemptions. You can find more information about the fund's expenses, including annual expense ratios for the past five years, in the Financial Highlights section of this report. For additional information on operating expenses and other shareholder costs, please refer to the appropriate fund Information Statement dated October 30, 2006.

Schedule of Portfolio Holdings A complete schedule of portfolio holdings is filed with the SEC for the first and third quarters on Form N-Q. It is available at www.sec.gov, or by phone at 800-SEC-0330, or by mail at Public Reference Section, SEC, Washington, DC 20549 (duplicating fee required) or upon request from IPAIT at 800-872-4024. Portfolio holdings are also available monthly on the IPAIT website, www.IPAIT.org. Proxy Voting The SEC requires an annual report of the proxy voting record of the Trust. Because the investments allowable under Iowa law restrict the investments for IPAIT to securities to which proxy voting does not apply, IPAIT does not have a proxy voting policy and will report no proxy votes on the Form N-PX. Form N-PX is available at www.sec.gov, or by phone at 800-SEC-0330, or by mail at Public Reference Section, SEC, Washington, DC 20549 (duplicating fee required) or upon request from IPAIT at 800-872-4024. Other Information Units of IPAIT's Diversified Portfolio and Direct Government Obligation Portfolio are not insured by the FDIC or the U.S. Government. Investment products involve investment risk, including the possible loss of principal. Past performance is not predictive of future results, and the composition of each Fund's portfolio is subject to change. 27 Annual Approval of the Investment Adviser Agreement by the Board of Trustees Every year the Board considers the renewal of IPAIT's investment management agreement (the "IM Agreement") and throughout each year, reviews and evaluates the performance of and services provided by WB Capital Management Inc. (f/k/a Investors Management Group, Ltd.) ("WB Capital" or the "Investment Adviser"). The Board assesses the nature, scope and quality of the services provided by the personnel of the Investment Adviser and its affiliates, including administrative services, and compliance with legal and regulatory requirements. The Board also receives and assesses information regarding the services provided by certain unaffiliated service providers. At various times throughout the year, the Board also considers a range of information in connection with its oversight of the services provided. Among the matters considered throughout the year are: (a) fees (in addition to management fees) paid to the Investment Adviser and its affiliates, such as fees for marketing and distribution; (b) overall operating expenses; (c) the resources devoted to and compliance reports relating to the investment objective, policies and restrictions, and compliance with the Code of Ethics and the Investment Adviser's compliance policies and procedures; and (d) the nature, cost and character of any non-investment management services provided by the Investment Adviser and its affiliates. The Board considered the approval of the IM Agreement at two meetings in the second half of 2006. The first consideration was at its meeting on August 30, 2006. At that meeting the IM Agreement which had been previously approved by shareholders at the special meeting on December 9, 2005 was reviewed and discussed in connection with a review of all of IPAIT's service providers. This IM Agreement was to terminate as of December 31, 2006. At that meeting the Board of Trustees tabled the approval and continuation of the IM Agreement for the period after December 31, 2006 in consideration of further negotiation between the parties on fees. At the October 26, 2006 meeting the Board reviewed and approved the continuation of the IM Agreement for 2007, but with a fee reduction. The Board of Trustees also approved a fee reduction with another service provider. In the period prior to and at the Board meetings, the Board considered a wide range of information provided by WB Capital and the Board requested and received materials specifically relating to IPAIT, the IM Agreement and WB Capital. These materials included among other things (a) information on the investment performance of IPAIT compared to a similar group of money market funds and public programs; (b) information on fees and expenses of other funds of similar asset size; (c) sales and redemption data; (d) a discussion by the WB Capital management team regarding their experience, investment strategies and outlook; and (e) information on the profitability to the Investment Adviser. The Board of Trustees considered all factors deemed to be relevant to IPAIT and observed or concluded that: o the expectation that the operation of WB Capital and IPAIT's day-to-day management, including the portfolio managers, will remain unchanged for the foreseeable future; o WB Capital and its personnel (including particularly those personnel with responsibilities for providing services to IPAIT), resources and investment process will remain unchanged; o WB Capital will have access to the resources and personnel of West Bancorporation and its other subsidiaries; 28 Annual Approval of the Investment Adviser Agreement by the Board of Trustees (continued) o the financial viability of WB Capital will remain unchanged; o the terms of the IM Agreement were the same as those of the previous IM agreement, except for the fee reduction; o the nature, extent and quality of the services that WB Capital provided were reasonable and appropriate; o the investment performance of IPAIT over various periods was comparable to other similarly situated public money funds; o the advisory fee rate payable to WB Capital by IPAIT and by other client accounts managed by WB Capital as proposed was a reduction from previous fees and was reasonable; o the total expense ratio of IPAIT compared to similar funds managed by other advisers was reasonable; o compensation payable by IPAIT to WB Capital for other services was reasonable; o the profitability of the IM Agreement to WB Capital compared to the profitability of the prior agreements when WB Capital was owned by AMCORE and the projected profitability of the New IM Agreement to West Bancorporation had declined substantially; o economies of scale would be realized from the fee structure as IPAIT grows. The Board considered the level and depth of knowledge of WB Capital. In evaluating the quality of services provided by WB Capital, the Board took into account its familiarity with WB Capital's management through board meetings, conversations and reports since IPAIT's inception. In considering the approval of the new Investment Management Agreement, the Board did not identify any single factor as controlling. Based on the Board's evaluation of all factors that it deemed to be relevant, the Board unanimously approved the IM Agreement for the period commencing January 1, 2007 and ending December 31, 2007. 29 BOARD OF TRUSTEES Tom Hanafan, Mayor, Council Bluffs, Craig Hall, Manager, Brooklyn Chair and Trustee Municipal Utility, Trustee Dianne Kiefer, Treasurer, Wapello Jody Smith, Director of County, Vice Chair and Trustee Administrative Services, City of Leon Rodas, General Manager, Spencer West Des Moines, Trustee Municipal Utility, Second Vice Chair Bob Haug, Executive Director, Iowa and Trustee Association of Municipal Utilities, Don Kerker, Director of Finance Ex-Officio Member and Secretary and Administrative Services, Thomas Bredeweg, Executive Director, Muscatine Power and Water, Trustee Iowa League of Cities, Ex-Officio Richard heidloff, Treasurer, Lyon Member and Treasurer County, Trustee William Peterson, Executive Director, Floyd Magnusson, Supervisor, Iowa State Association of Counties, Webster County, Trustee Ex-Officio Member and Assistant Susan Vavroch, City Treasurer, Cedar Rapids, Trustee The Board of Trustees are not compensated for Board service.
