Attestation of financial statements

External audit is to a large extent a legal requirement in Norway, and is a regulated area. The Audit and Auditors Act requires all business enterprises with an annual turnover of at least NOK 5 million
to undergo an annual audit. All partnerships with more than 5 partners are required to have a statutory audit, and all limited liability companies are required to have a statutory audit.

Attestations to the Tax Authorities

The financial statements are the basis for taxation of the enterprise's income. This basis is adjusted for different measurement rules in the tax legislation. The enterprise's auditor
is required by law to attest the accounts adjusted for taxation purposes, which are supplied with the client's tax return. The auditor must also certify that the system for reporting wages and
withholding tax is functioning properly and attest the reported amounts on an annual basis.

Attestation of paid in share capital and changes in capital

It is required that the appointed auditor of the company certifies that the capital has been paid within the time limits before a Private Limited Liability Company or a Public Limited Liability Company is registered.

Other specific attestations

Certain specific attestations are required in certain industries, e.g. in relation to government grants
