   1.                                                   Please revise MD&A in
future annual and quarterly filings to more fully address the
                                                        following:

                                                              You disclose that
results for fiscal year 2022 were negatively impacted by certain
                                                            challenges,
including supply chain disruptions. Please discuss whether and how
                                                            supply chain
disruptions materially affect your outlook or business goals. Quantify
                                                            and disclose, to
the extent possible, how sales, profits, and/or liquidity have been
                                                            impacted and
discuss known trends or uncertainties resulting from mitigation efforts
                                                            undertaken,
including whether any mitigation efforts introduce new material risks,
                                                            including those
related to product quality, reliability, or approval.

                You disclose here, and in quarterly filings, that you are
experiencing ongoing
              inflationary cost increases. Please quantify and disclose the
impact of the inflationary
              pressures you experience, including the combined impact of
inflation and your LIFO
              inventory valuation method on cost of sales, gross profit, and
inventory. Expand your
              disclosures to also indicate the extent to which you are able to
pass increased costs on
              to customers, through surcharges, to mitigate inflationary
pressures.
Non-GAAP Financial Measures, page 37

2.       We note you present several non-GAAP performance measures in which you
eliminate
         the LIFO decrement charge you recorded in FY 2021. Please more fully
explain to us
         what the LIFO decrement charge represents and why you believe
eliminating it from non-
         GAAP performance measures is appropriate given your use of LIFO to
account for the
         majority of your inventory. Please also specifically address the
following:

                More fully explain to us how you determined the amount of the
LIFO decrement
              charge and the factors that resulted in the charge. In this
regard, we noted disclosures
              in current and prior year financial statements that indicate the
current costs of LIFO
              valued inventories would be substantially higher which seems to
indicate a
              potentially lower cost basis in older inventory balances; and

                More fully explain to us how you considered the guidance in
Question 100.04 of the
              Division of Corporation Finance   s Compliance & Disclosure
Interpretations on Non-
              GAAP Financial Measures in determining the non-GAAP performance
measures you
              present are appropriate.
Free Cash Flow, page 39

3.       We note your calculation of the non-GAAP liquidity measure you
identify as "free cash
         flow" appears to differ from the standard calculation of this measure
(i.e., cash flows from
         operations less capital expenditures). In order to avoid potential
confusion, please revise
         the title of your non-GAAP liquidity measure in future filings to
adjusted free cash flow
         or something similar. Refer to Question 102.07 of the Division of
Corporation Finance   s
         Compliance & Disclosure Interpretations on Non-GAAP Financial
Measures.
