Expense ExamplesAs a shareholder of one or more of the funds, you incurtwo types of costs: (1) transaction costs (for example,any contingent deferred sales charges that may apply onclass B or class C shares of Prime Obligations Fund);and (2) ongoing costs, including investment advisoryfees, distribution and/or service (12b-1) fees, and otherfund expenses. The examples below are intended to helpyou understand your ongoing costs (in dollars) ofinvesting in the funds and to compare these costs withthe ongoing costs of investing in other mutual funds.These examples are based on an investment of $1,000invested at the beginning of the period and held for theentire period from March 1, 2008, to August 31, 2008.Actual ExpensesFor each class of each fund, two lines are presented inthe table below — the first line for each class providesinformation about actual account values and actualexpenses. You may use the information in this line,together with the amount you invested in the particularfund and class, to estimate the expenses that you paidover the period. Simply divide your account value by$1,000 (for example, an $8,600 account value in thefund and class divided by $1,000 = 8.6), then multiplythe result by the number in the first line under theheading entitled “Expenses Paid During Period” toestimate the expenses you paid on your account duringthis period.Hypothetical Example for Comparison PurposesFor each class of each fund, the second line of the tablebelow provides information about hypothetical accountvalues and hypothetical expenses based on the respectivefund’s actual expense ratio and an assumed rate ofreturn of 5% per year before expenses, which is not thefund’s actual return. The hypothetical account valuesand expenses may not be used to estimate the actualending account balance or expenses you paid for theperiod. You may use this information to compare theongoing costs of investing in the fund and other funds.To do so, compare this 5% hypothetical example withthe 5% hypothetical examples that appear in theshareholder reports of the other funds.Please note that the expenses shown in the table aremeant to highlight your ongoing costs only and do notreflect any transactional costs, such as contingentdeferred sales charges. Therefore, the second line of thetable for each class of each fund is useful in comparingongoing costs only, and will not help you determine therelative total costs of owning different funds. Inaddition, if these transactional costs were included, yourcosts would have been higher.Government Obligations FundBeginning AccountValue (3/01/08)Ending AccountValue (8/31/08)Expenses Paid DuringPeriod 1 (3/01/08 to8/31/08)Class A Actual 2 $1,000.00 $1,008.80 $3.79Class A Hypothetical (5% return before expenses) $1,000.00 $1,021.37 $3.81Class D Actual 2 $1,000.00 $1,009.60 $3.03Class D Hypothetical (5% return before expenses) $1,000.00 $1,022.12 $3.05Class Y Actual 2 $1,000.00 $1,010.40 $2.27Class Y Hypothetical (5% return before expenses) $1,000.00 $1,022.87 $2.29Class Z Actual 2 $1,000.00 $1,011.60 $1.01Class Z Hypothetical (5% return before expenses) $1,000.00 $1,024.13 $1.02Institutional Investor Class Actual 2 $1,000.00 $1,011.10 $1.52Institutional Investor Class Hypothetical (5% return before expenses) $1,000.00 $1,023.63 $1.531 Expenses are equal to the fund’s annualized expense ratio for the most recent six-month period of 0.75%, 0.60%, 0.45%, 0.20%, and 0.30% for Class A, Class D,Class Y, Class Z, and Institutional Investor Class, respectively, multiplied by the average account value over the period, multiplied by the number of days in the mostrecent fiscal half-year/366 (to reflect the one-half year period).2 Based on the actual returns for the six-month period ended August 31, 2008 of 0.88%, 0.96%, 1.04%, 1.16%, and 1.11% for Class A, Class D, Class Y, Class Z, andInstitutional Investor Class, respectively.4 FIRST AMERICAN FUNDS 2008 Annual Report
