ASU No. 2016-09 Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting	The standard simplifies the accounting for share-based payment award transactions including: income tax consequences, classification of awards as either equity or liabilities and classification on the statement of cash flows. The provisions of this standard are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted.	The Company has adopted all amendments included in this standard under each required transition method.  The Company concluded there were no material changes to prior periods, except for the following: the Company (a) reclassified its prior interim period excess tax benefit for stock compensation of $941,000 on its consolidated statement of cash flows from a financing activity to an operating activity; and (b) recognized a cumulative-effect adjustment of $254,000 as an increase to retained earnings and decrease to additional paid-in capital on the Company's consolidated statement of shareholders' equity as of January 1, 2017 to reflect the change in value for a restricted stock unit liability award as of December 31, 2016, as if the award had been classified as an equity award since its respective grant date.

ASU No. 2017-04 Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment	The standard eliminates the "Step 2" analysis to determine the amount of impairment realized when a reporting unit's carrying amount exceeds its fair value in its "Step 1" analysis of accounting for impairment of goodwill. The impairment charge would be the amount determined in "Step 1." The provisions of this standard are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted for annual and interim goodwill impairment testing dates after January 1, 2017.	The Company has adopted this standard and it did not have any impact on the Company's consolidated financial statements. Date of Adoption: Q1 2017
ASU No. 2017-07 Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost	The standard requires an employer to recognize the service cost component of net periodic pension costs and net periodic postretirement benefit costs in the same line item(s) as other compensation costs from services rendered by pertinent employees during the period. Other components of net benefit cost are required to be presented separately from the service cost component and outside a subtotal of income from operations. The provisions of this standard are effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption is permitted as of the beginning of an annual period for which financial statements (interim or annual) have not been issued or made available for issuance.	The Company has adopted this standard and has applied it retrospectively for the presentation of the service cost component, as well as, other components of net periodic pension cost and net periodic postretirement benefit cost in our statement of operations. The adoption decreased selling, general, and administrative expense by $159,000 for the three months ended September 30, 2016 and $479,000 for the nine months ended September 30, 2016, and comparably increased other expense by the same amounts, respectively. This guidance did not have any impact on our balance sheet or our statement of cash flows. Date of Adoption: Q1 2017

Standard	Description	Financial Statement Effect or Other Significant Matters
ASU No. 2014-09 Revenue from Contracts with Customers (Topic 606) And All Related ASUs	The standard requires an entity to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard also requires additional disclosures about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and assets recognized from costs incurred to obtain or fulfill a contract. The provisions of the standard, as well as all subsequently issued clarifications to the standard, are effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. The standard can be adopted using either a full retrospective or modified retrospective approach.	The Company currently believes the most significant impact of this standard upon adoption relates to the revenue recognition for custom fabricated products within the Company's Industrial and Infrastructure Products segment. Under this standard, the Company expects to recognize revenue on an over time basis on custom fabricated products in the Industrial and Infrastructure Products segment which is a change from our current revenue recognition policy of point-in-time basis. The Company expects revenue recognition related to the remaining Industrial and Infrastructure Products segment, Residential Products segment and Renewable Energy and Conservation segment to remain substantially unchanged upon adoption of this standard. The Company has identified and is in the process of implementing appropriate changes to the Company's business processes, systems and internal controls to support recognition and disclosure under this standard. The Company currently anticipates adopting the modified retrospective transition method approach. The Company has not yet completed the process of quantifying the effects of any changes that will result from adoption. Planned date of adoption: Q1 2018

ASU No. 2016-02 Leases (Topic 842)	The standard requires lessees to recognize most leases as assets and liabilities on the balance sheet, but record expenses on the statement of operations in a manner similar to current accounting. For lessors, the guidance modifies the classification criteria and accounting for sales-type and direct financing leases. The standard also requires additional disclosures about leasing arrangements and requires a modified retrospective transition approach for existing leases, whereby the standard will be applied to the earliest year presented. The provisions of the standard are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted.	The Company is currently evaluating the impact of this standard on the Company's consolidated financial statements and related disclosures, including the impact on the Company's current lease portfolio from both a lessor and lessee perspective. The adoption of this standard will primarily result in an increase in the assets and liabilities on the Company's consolidated balance sheet and related disclosures. Planned date of adoption: Q1 2019

Early adoption is permitted as of the beginning of an annual reporting period for which financial statements (interim or annual) have not been issued or made available for issuance.
