The performance data quoted represents past performance. Past performance does not guarantee future results and current performance may be lower or higher than the performance data quoted. The investment return and principal value of your investment will fluctuate so that your shares, when redeemed, may be worth more or less than their original cost. The 365- and 360-day yields represent standard one-day yield for the funds. The 30-day simple yields represent annualized results for the period, net of fees and expenses and exclude any realized capital gains or losses.

¹ The 7-day SEC yield(s) reflect fee waivers and/or expense reimbursements in effect for the period. Had the Adviser and/or Distributor not waived fees and/or reimbursed expenses, the 7-day SEC yield(s) would have been lower.

^a Reflects total Portfolio assets.

^b The factor is the amount of income per share earned on securities held by the portfolio on a daily basis.

^c Market Value NAV: Net asset value (NAV) per share based on available market quotations of the portfolio's securities as provided by a third party pricing vendor as of the date stated. The mark to market valuation methodology includes marking all securities of the Portfolio. The Market Value NAV should not be viewed as indicative of future Market Value NAVs or the future performance of any of the Portfolios set forth above and should not be relied upon for purposes of making an investment decision. The Market Value NAV may change from day to day. Market Value NAVs are released at approximately 10:30 a.m. CT as of the date stated. The Market Value NAV does not reflect the price at which an investor may transact in shares of the Portfolios, and the forgoing should not be considered an offer to purchase or sell of any Portfolio at such price.

^d Weighted Average Maturity (WAM) - The length of time until the average security in a fund matures or will be redeemed by its issuer. It indicates a fixed income fund's sensitivity to interest rate changes. Longer average weighted maturity implies greater volatility in response to interest rate changes, while shorter average weighted maturity implies less volatility. WAM is calculated in days.

^e Weighted average life (WAL) - A measure of a money market fund's sensitivity to changes in credit spreads and other spread risks. Weighted average life, which is expressed in days, is calculated by summing the remaining maturity of each portfolio security or, when relevant, the number of days until the date of the next demand feature when the fund may receive payment of principal and interest, scaled by that security's share of the portfolio's total value, as measured by amortized cost. Weighted average life differs from weighted average maturity (WAM) in that the weighted average life calculation uses a variable-rate security's final maturity (or the date of the next demand feature); the weighted average maturity calculation uses the security's next interest rate reset date. Thus, weighted average life should always be equal to or greater than the weighted average maturity.
