Change In Accounting For Employee Share-Based Payment Accounting | Change in Accounting for Employee Share-Based Payments ﻿ As of January 1, 2017 we made an entity-wide accounting policy election in accordance with ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, (“ASU 2016-09”) to change our accounting policy to account for stock compensation forfeitures in the period awards are forfeited rather than estimating the effect of forfeitures. We elected to make this accounting policy change to simplify the accounting for share-based compensation and believe this method provides a more accurate reflection of periodic share-based compensation cost from the grant date forward. We used the modified retrospective transition method to record a net $238,000 cumulative-effect adjustment decrease to retained earnings for the accounting policy change, which included a $379,000 increase to additional paid in capital and a $141,000 increase in deferred tax assets. ﻿ Additionally, as of January 1, 2017 and in accordance with the guidance in ASU 2016-09, we made a change to account for excess tax benefits and deficiencies resulting from the settlement or vesting of share-based awards in income tax expense on our Summary Consolidated Statement of Operations and Comprehensive Income, instead of accounting for these effects through additional paid in capital on our Summary Consolidated Balance Sheets. We applied this amendment prospectively and prior periods have not been adjusted.
