Generally, rising gasoline prices benefit net sales growth which, given the higher sales base, negatively impacts our gross margin percentage but decreases our selling, general and administrative [added: (SG&A)] expenses as a percentage of net sales.

[added: Rather, we believe that] achieving our longer-term objectives of reducing employee turnover and enhancing employee satisfaction requires maintaining compensation levels that are better than the industry average for much of our workforce.

New in FY2017

In the first fiscal quarter of 2017, we increased our annual membership fees in certain of our Other International operations.

New in FY2017

Effective June 1, 2017, we also increased our annual membership fees in the U.S. and Canada for Gold Star (individual), Business and Business add-on by $5 to $60 and for Executive Membership from$110 to $120 (annual membership fee of $60, plus the Executive upgrade of $60); and the maximum 2% reward associated with Executive Membership increased from $750 to $1,000 annually.

New in FY2017

We account for membership fee revenue on a deferred basis, recognized ratably over the one-year membership period.

New in FY2017

These fee increases had a positive impact on membership fee revenues during 2017 of approximately $23 and will positively impact the next several quarters.

New in FY2017

We expect these increases to positively impact membership fee revenue by approximately $175 in fiscal 2018.

2017 vs. 2016

New in FY2017

Total gross margin percentage decreased two basis points compared to 2016.

New in FY2017

This increase was primarily due to amounts earned under the co-branded credit card arrangement in the U.S. of 15 basis points and a benefit of three basis points from non-recurring legal settlements and other matters.

New in FY2017

The improvement in terms in our current co-brand agreement as compared to the prior co-brand arrangement led to substantial year over year benefits in fiscal 2017.

New in FY2017

Changes of comparable magnitude will not occur in subsequent years.

New in FY2017

These increases were partially offset by a six basis point decrease in our core merchandise categories, primarily due to food and sundries as a result of a decrease in sales penetration.

New in FY2017

The gross margin percentage was also negatively impacted by five basis points due to a LIFO benefit in 2016 and one basis point in warehouse ancillary and other businesses.

New in FY2017

Gross margin on a segment basis, when expressed as a percentage of the segment's own sales and excluding the impact of changes in gasoline prices on net sales (segment gross margin percentage), increased in our U.S. operations, due to amounts earned under the co-branded credit card arrangement and non-recurring legal settlements and other matters as discussed above.

New in FY2017

These increases were partially offset by a decrease in core merchandise categories, predominantly food and sundries as a result of a decrease in sales penetration, and a LIFO benefit in 2016.

New in FY2017

The segment gross margin percentage in our Canadian operations increased, primarily due to increases in warehouse ancillary and other businesses, primarily our pharmacy business, partially offset by a decrease in our core merchandise categories, largely fresh foods.

SG&A expenses as a percentage of net sales decreased 14 basis points compared to 2016.

Operating costs related to warehouses, ancillary, and other businesses, which includes e-commerce and travel, were lower by nine basis points, primarily due to lower costs associated with the co-branded credit card arrangement in the U.S. of 18 basis points.

The improvement in terms in our current co-brand agreement as compared to the prior co-brand arrangement led to substantial year over year benefits in fiscal 2017.

New in FY2017

Changes of comparable magnitude will not occur in subsequent years.

New in FY2017

This was partially offset by higher payroll and employee benefit expenses of 11 basis points, primarily in our U.S. operations.

increase in hardlines, partially offset by food and sundries due to a decrease in sales penetration.

Dropped from FY2016

Our gross margin percentage increased 43 basis points compared to 2014 and most of the improvement was derived from the impact of gasoline price deflation on net sales.

Dropped from FY2016

Excluding this impact, gross margin as a percentage of adjusted net sales was 10.81%, an increase of 15 basis points from the prior year.

Dropped from FY2016

This increase was predominantly due to: an increase in our warehouse ancillary and other business gross margin of 23 basis points, due primarily to our gasoline business; partially offset by a negative contribution from core merchandise categories of 12 basis points, as a result of a decrease in their sales penetration.

Dropped from FY2016

A LIFO benefit in 2015 compared to a charge in 2014 positively contributed five basis points.

Dropped from FY2016

The LIFO benefit resulted largely from lower costs of gasoline.

Dropped from FY2016

Segment gross margin percentage increased in our U.S. operations, primarily due to our gasoline business and the LIFO benefit discussed above.

Dropped from FY2016

The segment gross margin percentage in our Other International operations decreased, primarily in food and sundries.

Dropped from FY2016

Our investment in modernizing our information systems is ongoing and expected to continue to negatively impact SG&A expenses.

Dropped from FY2016

SG&A expenses as a percentage of net sales increased 18 basis points, mostly due to the negative impact of gasoline price deflation on net sales.

Dropped from FY2016

This was due to lower warehouse operating costs of 16 basis points, primarily from improvements in payroll expenses in our core business as a result of leveraging increased sales.

Dropped from FY2016

Higher stock compensation expense also negatively impacted our SG&A expenses by four basis points, due to an appreciation in the trading price of our stock at the time of grant.

Dropped from FY2016

The increase in interest expense is primarily due to the Senior Notes issued in February 2015.

Dropped from FY2016

The increase in net foreign-currency transaction gains was primarily attributable to favorable mark-to-market adjustments for forward foreign exchange contracts compared to the prior year.

The increase was also attributable to net gains on the revaluation or settlement of monetary assets and liabilities during the year.

Accordingly, we no longer consider that portion to be indefinitely reinvested.

Dropped from FY2016

The primary uses of cash in 2016 were related to the $1,200 repayment of our 0.65% Senior Notes in December 2015, dividend payments of $746, repurchases of common stock, and payment of withholding taxes on stock-based awards.
