Abstract
We form generating series, valued in the Chow group and the arithmetic Chow group, of special divisors on the compactified integral model of a Shimura variety associated to a unitary group of signature pn ´1, 1q, and prove their modularity.The main ingredient in the proof is the calculation of vertical components appearing in the divisor of a Borcherds product on the integral model.
