Prior to 4/30/2014, performance shown for Institutional share class.

The advisor has contractually agreed to waive management fees and/or reimburse the Fund’s operating expenses in order to limit the Fund’s total annual fund operating expenses to 1.10% of average daily net assets of the Fund for Institutional Class and 1.35% for Investor Class. The agreement will continue in effect at least through October 31, 2018, subject thereafter to annual re-approval of the agreement by the Fund’s Board of Directors. The Fund’s shareholders indirectly bear the expenses of the other funds in which the Fund invests (Acquired Funds). The operating expenses may not correlate to the expense ratio in the Financial Highlights in this Fund’s prospectus, because the Financial Highlights include only the operating expenses incurred by the Fund, not the indirect costs of investing in the Acquired Funds.

Cortina Funds will deduct a 2.00% redemption proceeds fee on Fund shares held 60 days or less. Performance data does not reflect the deduction of fees or taxes, which if reflected, would reduce the performance quoted. For more complete information including charges, risks and expenses, read the prospectus carefully.

Past performance does not guarantee future results. The performance data quoted represents past performance and current returns may be lower or higher.
