Pension and other postretirement plans, policy
The defined benefit pension plans of Bristow Helicopters and BIAGL replaced by the defined contribution plans described above covered all full-time employees of Bristow Aviation and BIAGL employed on or before December 31, 1997. Both plans were closed to future accrual as of February 1, 2004. The defined benefits for employee members were based on the employee’s annualized average last three years’ pensionable salaries up to February 1, 2004, increasing thereafter in line with retail price inflation (prior to 2011) and consumer price inflation (from 2011 onwards), and subject to maximum increases of 5% per year over the period to retirement. Any valuation deficits are funded by contributions by Bristow Helicopters and BIAGL. Plan assets are held in separate funds administered by the plans’ trustee (the “Trustee”), which are primarily invested in equities and debt securities. For members of the two closed defined benefit pension plans, since January 2005, Bristow Helicopters contributes a maximum of 7% of a participant’s non-variable salary, and since April 2006, the maximum employer contribution into the plan has been 7.35% for pilots. Each member is required to contribute a minimum of 5% of non-variable salary for Bristow Helicopters to match the contribution. In addition, there are three defined contribution plans for staff who were not members of the original defined benefit plans, two of which are closed to new members.
Bristow Norway had a final salary defined benefit pension plan, which was closed on March 1, 2016 as discussed above. Under this plan, pilots could have retired from age 58 and other employees from age 62 (after meeting certain criteria). Bristow Norway also participates in the standard Norwegian Avtalefestet pension (contractual pension or “AFP”), which is accounted for as a defined contribution plan. The pension benefit was a percentage of final salary in excess of a deductible. The maximum pension was available to those with 30 or more years of service as of the date of retirement. Additionally, there were associated death and disability benefits. Plan assets were held in an insurance policy with an insurance company and contributions followed Norwegian rules, which were based on an individual actuarial calculation for each plan member.
The closure of the Bristow Norway final salary plan on March 1, 2016 has led to a curtailment and settlement of the projected benefit obligations. All active members of the plan have been transferred to the new defined contribution for future service and the accrued individual insurance reserves for the majority of the beneficiaries will be transferred to individual insurance policies shortly after the 2016 financial year end. The remaining liabilities in respect of partially disabled beneficiaries are similarly expected to be settled before the end of the 2017 fiscal year end.
We utilize a British pound sterling denominated AA corporate bond index as a basis for determining the discount rate for our U.K. plans and NOK-denominated corporate bonds that are credit-rated AA or AAA as a basis for determining the discount rate for our Norway plan. The expected rate of return assumptions have been determined following consultation with our actuarial advisors. In the case of bond investments, the rates assumed have been directly based on market redemption yields at the measurement date, and those on other asset classes represent forward-looking rates that have typically been based on other independent research by investment specialists.
Under U.K. and Guernsey legislation, it is the Trustee who is responsible for the investment strategy of the plans, although day-to-day management of the assets is delegated to a team of regulated investment fund managers. The Trustee of the Bristow Staff Pension Scheme (the “Scheme”) has the following three stated primary objectives when determining investment strategy:
(i)
“funding objective” - to ensure that the Scheme is fully funded using assumptions that contain a modest margin for prudence. Where an actuarial valuation reveals a deficit, a recovery plan will be put in place which will take into account the financial covenant to the employer;
(ii)
“stability objective” - to have due regard to the likely level and volatility of required contributions when setting the Scheme’s investment strategy; and
(iii)
“security objective” - to ensure that the solvency position of the Scheme (as assessed on a gilt basis) is expected to improve. The Trustee will take into account the strength of the employer’s covenant when determining the expected improvement in the solvency position of the Scheme.
The types of investments are held, and the relative allocation of assets to investments is selected, in light of the liability profile of the Scheme, its cash flow requirements, the funding level and the Trustee’s stated objectives. In addition, in order to avoid an undue concentration of risk, assets are diversified within and across asset classes.
In determining the overall investment strategy for the plans, the Trustee undertakes regular asset and liability modeling (“ALM”) with the assistance of their U.K. actuary. The ALM looks at a number of different investment scenarios and projects both a range and a best estimate of likely return from each one. Based on these analyses, and following consultation with us, the Trustee determines the benchmark allocation for the plans’ assets.
The measurement date adopted is March 31. For the purposes of amortizing gains and losses, the 10% corridor approach has been adopted and assets are taken at fair market value. Any such gains or losses are amortized over the average remaining life expectancy of the plan members.
Share-based compensation, option and incentive plans policy
We use a Black-Scholes option pricing model to estimate the fair value of share-based awards. The Black-Scholes option pricing model incorporates various assumptions, including the risk-free interest rate, volatility, dividend yield and the expected term of the options.
The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for a period equal to the expected term of the option. Expected volatilities are based on the historical volatility of shares of our Common Stock, which has not been adjusted for any expectation of future volatility given uncertainty related to the future performance of our Common Stock at this time. We also use historical data to estimate the expected term of the options within the option pricing model and groups of employees that have similar historical exercise behavior are considered separately for valuation purposes. The expected term of the options represents the period of time that the options granted are expected to be outstanding. Additionally, we estimate pre-vesting option forfeitures at the time of grant and periodically revise those estimates in subsequent periods if actual pre-vesting forfeitures differ from those estimates. We record stock-based compensation expense only for those awards expected to vest using an estimated forfeiture rate based on our historical forfeiture data.
