What this fund is
Objective, as filed

Columbia Select Mid Cap Value Fund (the Fund) seeks long-term capital appreciation.

Strategy, summarised

The fund invests at least 80% of assets in mid-cap equity securities that meet value criteria—either constituents of the Russell 3000 Value Index or stocks with above-median book-to-price ratios, EBITDA-to-enterprise-value, or below-median price-to-earnings ratios within their sector. The manager typically holds 30 to 50 securities and may concentrate holdings in financials and industrials. Because the fund's selection depends on the manager's assessment of undervaluation and growth potential, performance will diverge from any benchmark.
