# Benefits
An unlimited company has the benefit and status of incorporation, the same as its limited company counterpart. Situations for which an unlimited company will be preferred to an alternative business model or its limited company counterpart include these:
* secrecy concerning financial affairs is desired, effectively shielding and protecting its financial affairs from public, media and competitor analysis, making them non-public information, including shareholder dividend payments: a United Kingdom unlimited company, unlike its limited company counterpart, is by the very nature of its legal liability generally not required to publish or make public its company financial statements (file its annual financial accounts at Companies House). * the company is active or trading in an area where limited liability is not acceptable, vital or practical, but perpetual succession is important. * extending, in general, a greater assurance and confidence to creditors and trade financial transactions, in contrast to its ''limited company'' counterpart. * there is a low risk of insolvency. * the company or its trading activities has or generates sufficient capital, funds or financing without need to approach general lenders such as high-street retail banks. * developing more advantageous company and business capital strategies in an ever-increasing irreversible trend of bank disintermediation by companies and their management. * a focused higher standard of board of directors and senior management|executive management behaviour (or probity) and business model for risk management. * a flow-through entity is required for United States federal tax purposes, under the Corporate tax in the United States#Entity classification|entity classification rules.
Once formed or incorporated, an unlimited company can, in some jurisdictions, also re-register and designate itself to limited company status at any time with few formalities, the same also extending to a limited company, which may at any time re-register and designate itself to unlimited company status.
