service cost for the DB Pension Plan in 2015.
The estimated period of amortization of these new prior service costs (credits) for CMS Energy and Consumers is ten years.
CMS Energy and Consumers determine the MRV for DB Pension Plan assets as the fair value of plan assets on the measurement date, adjusted by the gains or losses that will not be admitted into the MRV until future years.
CMS Energy and Consumers reflect each year’s gain or loss in the MRV in equal amounts over a five-year period beginning on the date the original amount was determined.
CMS Energy and Consumers determine the MRV for OPEB Plan assets as the fair value of assets on the measurement date.
Reconciliations: Presented in the following table are reconciliations of the funded status of CMS Energy’s and Consumers’ retirement benefits plans with their retirement benefits plans’ liabilities:
## Table 0 ##
The actuarial loss for 2016 was primarily the result of claims, experience, and lowering the discount rates used in calculating the plans’ obligations.
The actuarial gain for 2015 was primarily the result of increasing the discount rates used in calculating the plans’ obligations.
Medtronic plc Notes to Consolidated Financial Statements (Continued) The following table provides the weighted average fair value of options granted to employees and the related assumptions used in the Black-Scholes model:
## Table 1 ##
(1) Expected life: The Company analyzes historical employee stock option exercise and termination data to estimate the expected life assumption.
The Company calculates the expected life assumption using the midpoint scenario, which combines historical exercise data with hypothetical exercise data, as the Company believes this data currently represents the best estimate of the expected life of a new employee option.
The Company also stratifies its employee population into two groups based upon distinctive exercise behavior patterns.
(2) Risk-free interest rate: The rate is based on the grant date yield of a zero-coupon U. S.  Treasury bond whose maturity period equals the expected term of the option.
(3) Volatility: Expected volatility is based on a blend of historical volatility and an implied volatility of the Company’s ordinary shares.
Implied volatility is based on market traded options of the Company’s ordinary shares.
(4) Dividend yield: The dividend yield rate is calculated by dividing the Company’s annual dividend, based on the most recent quarterly dividend rate, by the closing stock price on the grant date.
Stock-Based Compensation Expense Under the fair value recognition provisions of U. S.  GAAP for accounting for stockbased compensation, the Company measures stock-based compensation expense at the grant date based on the fair value of the award and recognizes the compensation expense over the requisite service period, which is generally the vesting period.
The amount of stock-based compensation expense recognized during a period is based on the portion of the awards that are ultimately expected to vest.
The Company estimates pre-vesting forfeitures at the time of grant by analyzing historical data and revises those estimates in subsequent periods if actual forfeitures differ from those estimates.
Ultimately, the total expense recognized over the vesting period will equal the fair value of awards that actually vest.
Pursuant to the Transaction Agreement, outstanding stock option awards held by Covidien employees upon transaction close were converted into options to acquire the Company’s ordinary shares in a manner designed to preserve the intrinsic value of such awards.
In addition, unvested restricted stock units granted on or after June 15, 2014 which were held by Covidien employees upon close of the Covidien acquisition were converted into restricted stock units of the Company in a manner designed to preserve the intrinsic value of such awards.
The modifications made to the restricted stock units granted on or after June 15, 2014 and all outstanding share options pursuant to the Transaction Agreement that converted such awards constituted modifications under the authoritative guidance for accounting for stock compensation.
This guidance requires the Company to revalue the award upon the transaction close and allocate the revised fair value between consideration paid and continuing expense based on the ratio of service performed through the transaction date over the total service period of the award.
The revised fair value allocated to post-combination services resulted in incremental expense which is recognized over the remaining service period of the award.
The Company recognized $58 million of incremental expense related to these modifications during fiscal year 2016 and is included in acquisition-related items.
Except for the conversion of share options and restricted stock units discussed herein, the material terms of these awards remained unchanged.
