Your Tax Advisor will discuss your UK residence status during your Exit meeting and will cover the associated tax implications. On the understanding that you will qualify as a "Non-Resident" in the UK under the Statutory Residence Tests, your employment income should not be liable to UK tax. In addition, it is ABL policy to meet the cost of any income or social tax liabilities that may arise in Bermuda.

Should your residence status revert to "UK Resident" prior to the end of the assignment, then to the extent that this has occurred due to Company requirements, the Company will cover the cost of any retrospective UK tax liabilities that may arise on Aspen related remuneration together with the associated costs of amendments to tax returns. Should you lose "Non Resident'' status for UK tax purposes due to your personal decision or circumstances, then you will personally be responsible for retrospective UK taxes that may arise.

As a professional employee you will not be entitled to paid overtime. You will adhere to ABL internal guidelines, including all compliance rules pertaining to your function.

Local law: The terms and conditions of your UK employment, subject to the specific provisions of this letter, will remain in force and governed by the laws of England and Wales.

End of secondment: We anticipate that the period of your assignment in Bermuda will be 3 years, although ABL, with the agreement of AIUKSL and you, may extend this.

Except in the case of gross misconduct, you will be given 6 months' notice in the unlikely event that ABL decides to end your assignment and repatriate you to the UK before the end of the 3 year term.
