What constitutes the sum in the gross investment of the lease?

The sum in the gross investment of the lease is best represented by the lease payments and any anticipated residual value. This approach accurately reflects the total financial commitment involved in a lease arrangement.

Lease payments are critical as they represent the recurring cash inflows that the lessor can expect to receive over the lease term. Additionally, the anticipated residual value is significant because it accounts for the expected value of the leased asset at the end of the lease term. This value is essential in determining the overall return on investment for the lessor, as it influences the total benefit derived from the asset after the lease concludes.

Including both these components provides a comprehensive picture of the lease's financial implications, highlighting not only the immediate cash flows from payments but also the longer-term value of the asset involved. This complete view is crucial for financial reporting and investment analysis, ensuring that stakeholders understand the extent of the investment and the potential returns associated with the leased asset.
