When she returns to her office, Lin conducts a thorough analysis of GR. Based on her research, including discussions with some of GR’s customers, Lin is convinced that GR’s reported 50% increase in net income during recent quarters is completely fictitious. Lin is the only analyst suspicious about GR’s reported earnings so far, however.
