Allianz NACM Mid-Cap Growth Fund will normally invest in common stocks of companies with medium market capitalizations. The Fund may utilize foreign currency exchange contracts, options, stock index futures contracts and other derivative instruments. In response to unfavorable market and other conditions, the Fund may deviate from its principal strategies by making temporary investments of some or all of its assets in high-quality fixed income securities, cash and cash equivalents. The stocks of medium-sized companies may be more volatile than the stocks of larger companies.
