"There is a constant conflict faced by vendors and purchasers as to which option should be adopted," said Ms van Heerden. "In an asset sale, the purchaser can pick and choose the assets it wants to buy, and have some certainty around the liabilities to be assumed. Effectively, a share sale involves a complete transfer of everything a company owns, including the kitchen sink."
Toni Palmer, a partner in the Tauranga office of Tabak Business Sales, which specialises in advising on the sale and acquisition of small to medium-sized enterprises, said the asset sale was the most common option for the firm's clients.
"It means any residual liabilities lying within the company not passed on to a new owner," she said. "Share-based sales are most often between related parties who have previous knowledge of the business, or when there is some unique contract or advantage that cannot be transferred out of the company."
Ms van Heerden said while there were pros and cons for each option, a number of risks were often overlooked.
"In a share sale, the new owner can be held responsible for tax liabilities and other past debts which even the vendor was unaware of. And if more than 51 per cent of shares are acquired, there is a risk the company may forfeit tax losses in the year of the sale. It may also risk losing imputation credits if more than 34 per cent of the shares are acquired.
"In an asset sale, key contracts often can't be passed on without express permission from the third party involved. This means special deals or rates that the previous owner had locked in place might not continue once the business changes hands, making it less profitable."
