We also completed the acquisition of JanPak which extended our leadership as the largest national, broad-line JanSan platform in the United States, expanded our geographic footprint and product offering, and enhanced the depth and breadth of our customer base and team. Earlier in the year, we transitioned to a privately-held company with our partners at Goldman Sachs and P2 Capital.

Daily Sales Calculations

(1)         Average daily sales are defined as sales for a period of time divided by the number of shipping days in that period of time.

(2)         Average organic daily sales are defined as sales for a period of time divided by the number of shipping days in that period of time excluding any sales from acquisitions made subsequent to the beginning of the prior year period.

Average organic daily sales is presented herein because we believe it to be relevant and useful information to our investors since it is used by management to evaluate the operating performance of our business, as adjusted to exclude the impact of acquisitions, and compare our organic operating performance with that of our competitors. However, average organic daily sales is not a measure of financial performance under US GAAP and it should be considered in addition to, but not as a substitute for, other measures of financial performance reported in accordance with US GAAP, such as net sales. Management utilizes average organic daily sales as an operating performance measure in conjunction with US GAAP measures such as net sales.

Adjusted Operating Income

Adjusted Operating Income differs from US GAAP operating income. We define Adjusted Operating Income as operarting income plus the fees and expenses related to the merger and the accelerated share-based compensation resulting from the Merger. Adjusted Operating Income is presented herein because we believe it to be relevant and useful information to our investors since it is consistently used by our management to evaluate the overall operating performance of our business and to compare our operating performance with prior periods. Adjusted Operating Income excludes certain items, which we believe are not indicative of our core operating results. We therefore utilize Adjusted Operating Income as a useful alternative to net income as indicators of our operating performance compared to the Company’s plan. However, Adjusted Operating Income is not a measure of financial performance under US GAAP. Accordingly, Adjusted Operating Income should not be used in isolation or as a substitute for other measures of financial performance reported in accordance with US GAAP, such as gross margin, operating (loss) income, net (loss) income, cash flows (used in) provided by operating, investing and financing activities or other income or cash flow statement data prepared in accordance with US GAAP. While we believe that some of the items excluded from Adjusted Operating Income are not indicative of our core operating results, these items do impact our income statement, and management therefore utilizes Adjusted Operating Income as an operating performance measure in conjunction with US GAAP measures, such as gross margin, operating (loss) income, net (loss) income, cash flows (used in) provided by operating, investing and financing activities or other income or cash flow statement data prepared in accordance with US GAAP.

EBITDA, Adjusted EBITDA, and Further Adjusted EBITDA

We define EBITDA as net income (loss) adjusted to exclude interest expense, net of interest income;  provision (benefit) for income taxes; and depreciation and amortization.

We define Adjusted EBITDA as EBITDA adjusted to exclude merger-related expenses associated with the acquisition of the Company by affiliates of GS Capital Partners and P2 Capital Partners; share-based compensation, which is comprised of non-cash compensation arising from the grant of equity incentive awards; loss on extinguishment of debt, which is comprised of gains and losses associated with specific significant financing transactions such as writing off the deferred financing costs associated with our previous asset-based credit facility; distribution center consolidations and restructuring costs, which are comprised of facility closing costs, such as lease termination charges, property and equipment write-offs and headcount reductions, incurred as part of the rationalization of our distribution network, as well as employee separation costs, such as severance charges, incurred as part of a restructuring; and acquisition-related costs, which includes our direct acquisition-related expenses, including legal, accounting and other professional fees and expenses arising from acquisitions, as well as severance charges, stay bonuses, and fair market value adjustments to earn-outs.

Further Adjusted EBITDA is defined as Adjusted EBITDA further adjusted to exclude equity-related public company costs, which are comprised of certain board of director fees and travel expenses, filing, listing, transfer agent, equity administration, proxy services and annual meeting of stockholder fees and estimated expenses associated with investor relations such as consultants and travel that we believe we will not need to incur after the Merger; and include the sum of (i) the estimated Adjusted EBITDA impact of the acquisition of Pyramid II Janitorial Supplies and Equipment, Inc. as if we had acquired it on January 1, 2012, which is comprised of its estimated EBITDA for the six-month period ended June 30, 2012 and the actual EBITDA for the six-months ended December 28, 2012 plus first year synergies expected to be attained, and (ii) the estimated Adjusted EBITDA impact of the acquisition of JanPak, Inc. as if we had acquired it on January 1, 2012, which is comprised of its estimated EBITDA for the period from January 1, 2012 to December 11, 2012 and the actual EBITDA for the period from December 12, 2012 to December 28, 2012 plus first year synergies expected to be attained.

EBITDA, Adjusted EBITDA and Further Adjusted EBITDA differ from Consolidated EBITDA per our asset-based credit facility agreement for purposes of determining our net leverage ratio and EBITDA as defined in our indentures. We believe EBITDA, Adjusted EBITDA and Further Adjusted EBITDA allow management and investors to evaluate our operating performance without regard to the adjustments described above which can vary from company to company depending upon the acquisition history, capital intensity, financing options and the method by which its assets were acquired. While adjusting for these items limits the usefulness of these non-US GAAP measures as performance measures because they do not reflect all the related expenses we incurred, we believe adjusting for these items and monitoring our performance with and without them helps management and investors more meaningfully evaluate and compare the results of our operations from period to period and to those of other companies. Actual results could differ materially from those presented. We believe these items for which we are adjusting are not indicative of our core operating results. These items impacted net income over the periods presented, which makes direct comparisons between years less meaningful and more difficult without adjusting for them. While we believe that some of the items excluded in the calculation of EBITDA, Adjusted EBITDA and Further Adjusted EBITDA are not indicative of our core operating results, these items did impact our income statement during the relevant periods, and management therefore utilizes EBITDA, Adjusted EBITDA and Further Adjusted EBITDA as operating performance measures in conjunction with other measures of financial performance under US GAAP such as net income.

11

Operating Free Cash Flow

We define Operating Free Cash Flow as Adjusted EBITDA adjusted to include the cash provided by (used for) our core working capital accounts, which are comprised of accounts receivable, inventory and accounts payable, less capital expenditures. We believe Operating Free Cash Flow is an important measure of our liquidity as well as our ability to meet our financial commitments. We use operating free cash flow in the evaluation of our business performance. A limitation of this measure, however, is that it does not reflect payments made in connection with investments and acquisitions. To compensate for this limitation, management evaluates its investments and acquisitions through other return on capital measures.
