Many galaxies contain kinematically decoupled structures of different types, one such a type being counter-rotating stellar discs. Recently, full-spectral fitting techniques have been exploited to extract kinematical features and stellar population properties of counter-rotating discs from integrated light spectra of galaxies. Studies of stellar counter-rotating components in disc galaxies shed light on processes of accretion and mergers which are thought to be responsible for their formation. We present our study of lenticular galaxy NGC 448 which was classified as 2σ peak galaxy (Krajnovic et al 2011). We observed galaxy with the Russian 6-m telescope in the long-slit mode and used archival IFU data. We applied spectral decomposition technique to separate and measure kinematics and stellar populations of both the main stellar component and counter-rotating stellar components then discuss the origin of it.
