Final answer:
The additional paid-in-capital for Bertram Corporation increases on March 1, 2012, when the attorney accepted 5,000 shares of common stock for legal services valued at $45,000.
Step-by-step explanation:
The additional paid-in-capital would increase on March 1, 2012. This increase occurs because the corporation's attorney accepted 5,000 shares of common stock in settlement for legal services with a fair value of $45,000. Given that the par value is $1 per share, this transaction creates an additional paid-in-capital of $40,000 ($45,000 - $5,000). On February 1, 2012, the shares issued at par for cash would not have created any additional paid-in-capital since they were sold at their par value.
Additional paid-in-capital would increase on March 1, 2012 when the attorney accepted 5,000 shares of common stock in settlement for legal services. The fair value of the shares was $45,000, which is greater than their par value. The difference between the fair value and the par value ($45,000 - $5,000) would be recorded as additional paid-in-capital.
