Final answer:
To succeed in his suit, Larson must demonstrate that the misstatements were material and that they caused his loss.
Step-by-step explanation:
In a suit against Jay and Dart under the Section 11 liability provisions of the Securities Act of 1933, Larson must prove that the misstatements contained in Dart's financial statements were immaterial.
Under Section 11, a plaintiff does not need to prove that the audit was conducted properly or that Dart intentionally included the misstatements. The focus is on whether the misstatements were material, meaning they would have influenced a reasonable investor's decision to purchase the stock.
In this case, Larson suffered a loss when the misstatements became known. To succeed in his suit, Larson must demonstrate that the misstatements were material and that they caused his loss.
