SG&A for the first quarter of fiscal 2018 was $27.8 million compared to $25.8 million for the same period last year. As a percentage of net sales, SG&A was 16.9% for the first quarter of fiscal 2018 compared to 16.7% for the same period last year. The increase was primarily due to higher personnel related expenses of $1.3 million, $0.5 million of additional incentive stock compensation, and other items of $0.2 million.

For the first quarter of fiscal 2017 other operating expenses were comprised mainly of $2.2 million of amortization of intangibles.

Operating income for the first quarter of fiscal 2018 was $31.8 million compared to operating income of $29.2 million for the same period last year. Operating income as a percentage of net sales was 19.4% compared to 18.9% for the same period last year.

Income tax expense for the first quarter of fiscal 2018 was $7.6 million compared to $8.8 million for the same period last year. The effective income tax rate for the first quarter of fiscal 2018 was 25.8% compared to 32.7% for the same period last year. On April 2, 2017, the Company adopted a new accounting standard ASU No. 2016-09, “Improvements to Employee Share-Based Payment Accounting.” As a result of the adoption, the Company began recording the tax effects associated with stock-based compensation through the income statement on a prospective basis which resulted in a tax benefit of $2.3 million for the first three months of fiscal 2018. Prior to adoption, these amounts would have been recorded as an increase to additional paid-in capital. The adoption of this standard also resulted in a cumulative effect change to opening retained earnings of $1.1 million for previously unrecognized excess tax benefits.

Net income for the first quarter of fiscal 2018 was $21.8 million compared to $18.0 million for the same period last year. On an adjusted basis, net income for the first quarter of fiscal 2018 would have been $22.0 million compared to $18.1 million for the same period last year.

Diluted EPS for the first quarter of fiscal 2018 was 90 cents per share compared to 76 cents per share for the same period last year. On an adjusted basis diluted EPS for the first quarter of fiscal 2018 would have been 91 cents per share compared to diluted EPS of 77 cents per share for the same period last year. The adoption of ASU No. 2016-09 added approximately 9 cents to diluted and adjusted diluted EPS in the first quarter fiscal 2018.

Impact of New Accounting Standard

In March 2016, the FASB issued ASU No. 2016-09, “Improvements to Employee Share-Based Payment Accounting” which amends ASC Topic 718, Compensation - Stock Compensation. This ASU includes provisions intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. The Company adopted this standard on April 2, 2017. As a result of the adoption, the Company began recording the tax effects associated with stock-based compensation through the income statement on a prospective basis which resulted in a tax benefit of $2.3 million for the first three months of fiscal 2018. Prior to adoption, these amounts would have been recorded as an increase to additional paid-in capital. This change may create volatility in the Company’s effective tax rate going forward. The adoption of this standard resulted in a cumulative effect change to opening retained earnings of $1.1 million for previously unrecognized excess tax benefits.

Additionally, the Company will prospectively classify all tax-related cash flows resulting from share-based payments, including the excess tax benefits related to the settlement of stock-based awards, as cash flows from operating activities in the statement of cash flows. Prior to the adoption of this standard, these were shown as cash inflows from financing activities and cash outflows from operating activities.

The adoption of ASU No. 2016-09 also resulted in the Company removing the excess tax benefits from the assumed proceeds available to repurchase shares when calculating diluted earnings per share on a prospective basis. The revised calculation increased the diluted weighted average common shares outstanding by approximately 0.1 million shares. The Company made an accounting policy election to continue to estimate forfeitures as it did prior to adoption.
