The extension structure of the two-dimensional current algebra of nonlinear sigma models is analyzed by introducing Kostant Sternberg (L, M) systems. It is found that the algebra obeys a two-step extension by Abelian ideals. The second step is a non-split extension of a representation of the quotient of the algebra by the first step of the extension. The cocycle which appears is analyzed.
