2.We note you disclose for the quarter ended September 30, 2017, "the effective income
tax rate is lower due to a decrease in the estimated full-year income tax rate, which was
driven by a favorable change in jurisdictional mix of income as well as the positive
settlement of previous years' tax disputes."  With a view towards expanded disclosure,
please tell us the following:
-  the nature of the favorable change in jurisdictional mix of income;
- the basis for previous years' tax disputes which led to a positive settlement.  In this
regard, we note your Form 10-K disclosure on page F-23 regarding the total amounts
settled with RRD; and
- the nature of  any other tax disputes outstanding, if any.
            We remind you that the company and its management are responsible for the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action or absence of
action by the staff.
