A shareholder is a person or entity that owns shares in a company, giving them a share of its profits and value while the directors run the business.

Also known as: member, company member

Key points

  • In most Australian small and medium businesses the shareholders and directors are the same people, so the owner usually signs as guarantor too.
  • Lenders typically ask shareholders with a significant stake to give a personal guarantee, making them personally liable if the company defaults.
  • Under AML/CTF laws lenders must identify a company's beneficial owners: the natural persons behind 25% or more of the shares.
  • Most loan agreements require you to tell the lender about material changes in shareholding, and some need lender consent before shares are transferred.

Frequently asked questions

Do all shareholders have to guarantee a business loan?

Not always. Lenders typically require guarantees from shareholders holding a significant stake, and the exact cut-off depends on the lender's policy and the size of the facility. Shareholders below that threshold may not be asked, but anyone who does sign becomes personally liable for the company's debt if it defaults.

Can a shareholder's personal assets be at risk?

Yes, if the shareholder has signed a personal guarantee. The lender can pursue the guarantor's own assets, including property, savings and other investments, if the company defaults. The lender may also have taken security over those assets, such as a mortgage over the guarantor's home, when the loan was set up.

What happens if I sell my shares during the loan term?

Check the loan agreement for change-of-control provisions first. Many agreements require you to notify the lender of material changes in shareholding, and some need the lender's consent before shares can be transferred. The lender may also ask the incoming shareholder to provide a replacement guarantee. Talk to your lender or broker before you commit to the sale.

Do lenders check shareholders' personal credit history?

Yes. Lenders review the personal credit history, financial position and business experience of key shareholders as part of the overall credit assessment for the company. Because the shareholders of a small business are usually also its directors and guarantors, their personal finances carry real weight in the decision.

What if the borrowing company is the trustee of a trust?

Many businesses trade through a company acting as trustee of a family or discretionary trust. The trustee company is the borrower but the trust holds the assets, so the lender reviews the trust deed for the trustee's powers and any limits on borrowing or granting security. Shareholders of the trustee company and trust beneficiaries may be asked to guarantee.
