How do you say MATCHING GIFT in Spanish?

I work for a non-profit and we are looking to say MATCHING GIFT (http://www.google.com/search?hl=en&rlz=1C1_____enUS392US392&defl=en&q=define:Matching+gift&sa=X&ei=BrE4TeOON8_ogQfh5tj2CA&ved=0CBMQkAE) in Spanish for a brochure. Any ideas? I believe it is a technical term, not the direct translation that we are looking for.
