Final answer:
The accountant should provide a simplified summary and consider conducting a training session for the board members of Lisbon to enhance their understanding of the financial statements. Hiring a consultant could also be beneficial, but ignoring the issue is not advisable.
Step-by-step explanation:
To address the situation where board members of Lisbon have little understanding of accounting, the accountant should aim to provide a simplified summary of the financial statements during the presentation, ensuring that all transactions and events are explained in a way that is easily understandable for individuals without an accounting background. This summary should clearly articulate the implications and reasons behind each transaction, such as the sale and leaseback being treated as a secured loan, the significance of revaluing assets despite operating losses, and the impact of changing inventory valuation methods. Additionally, providing a brief but targeted training session before the formal presentation can help board members better understand key accounting principles and concepts relevant to the financial statements. Hiring a consultant is another option; though it may involve additional cost, they can offer expertise in simplifying complex information and supporting the accountant's explanation. Ignoring the issue would be unwise as it could lead to misinformed decision-making.
