                    File No. 1-16245

Dear Mr. Decker:

      W.P. Stewart & Co., Ltd. ("we" or the "Company") is hereby responding to
the comment letter of the Staff, dated August 8, 2007, in respect of the
Company's Annual Report on Form 20-F for the year ended December 31, 2006 (the
"Annual Report") filed with the Securities and Exchange Commission (the
"Commission") on April 2, 2007, the Company's Report on Form 6-K regarding the
Company's first quarter fiscal results for 2007 (the "First Quarter Report")
filed with the Commission on May 16, 2007, and the Company's Report on Form 6-K
regarding the Company's second quarter fiscal results for 2007 (the "Second
Quarter Report") filed with the Commission on August 3, 2007. Terms utilized in
this letter shall have the same meanings as were ascribed to them in the Annual
Report.

      The numbered paragraphs of the responses set forth below correspond to the
numbered comments in the Staff's letter.

      1. The Staff requested that, where applicable in response to the Staff's
letter, additional disclosures or revisions be shown in this response letter. We
have done so as shown below. Any additional disclosures or revisions will be
incorporated in the Company's future filings, including interim filings, with
the Commission where applicable.

      2. The Staff requested further information regarding the Company's
intangible asset and goodwill impairment analysis as of March 31, 2007 as it
relates to the intangible assets associated with the acquisition of TPRS
Services N.V.

            The first analysis which we provided in our initial response
regarding intangible assets related to TPRS Services N.V. indicated the asset
grouping would generate approximately $24 million of undiscounted future cash
flows attributed to the specific pool of identifiable customer accounts
supporting these intangible assets. This pool of customer accounts (the customer
intangible asset associated with the TPRS Services N.V. acquisitions in 1999 and
2000) is the lowest level grouping for which identifiable cash flows are largely
independent of the cash flows of other assets and liabilities. The first
analysis we provided was a high-level screen using first quarter net income to
roughly estimate cash flows without further refining known differences, such as
performance fees and related pay outs and non-cash expenses.

      In accordance with SFAS #144 (para. 17), in considering all available
evidence when evaluating the recoverability of this long-lived asset, our
refined cash flows in the additional analysis incorporates various assumptions
about our business operations and conditions which we believe are reasonable.
The additional analysis in Exhibit I(a) and I(b) shows the course of action
factoring in only cash expenses and an estimate for performance fees.
Performance fees have been earned from this asset group for the previous two
years and our updated budget for 2007 continues to provide for performance fees
from these accounts.

The carrying value of these intangible assets as of March 31, 2007 was
approximately $26 million. The additional cash flow analysis shows undiscounted
cash flows aggregating $39.2 million showing the recoverable amount to exceed
the carrying value by a significant margin. Accordingly, the Company determined
that there was no impairment charge to be recognized at March 31, 2007.

      The second quarter of 2007 brought a further reduction in the assets under
management due to a decline in market value and the closure of accounts within
this pool of customers. In light of these events, management made a decision
during the second quarter to revise our fee structure associated with certain
accounts within this pool of customers, as well as others. This was determined
to be a triggering event under SFAS #144 (para. 8) and upon completion of the
recoverability test and determination of the fair value of the asset group under
SFAS #144, it was determined that an impairment charge should be recognized at
June 30, 2007.

      3. The Staff inquired about the assumed expense rates of 54.1% and 58.8%
used in the Company's intangible asset and goodwill impairment analysis for the
five years ended December 31, 2006 and March 31, 2007, respectively.

            The expense rates of 54.1% and 58.8% were based on the ratio of
pre-tax expenses (including non-cash charges for depreciation, amortization and
non-cash compensation expense) and excluding one-time non-recurring charges
(consisting of a performance fee charge for the year ended December 31, 2006
based on the change in domicile of a mutual fund and a write-off of intangible
assets for the year ended December 31, 2005), to gross revenue for the five year
periods ended December 31, 2005 and 2006, respectively, in each case the most
recent five year period for which audited figures were available. The difference
in the rates was based solely on the actual average annual run rate for each
respective five year period and was attributable to a reduction in revenue and
an increase in operating expenses from 2001 to 2006. We note that application of
the higher expense ratio to the earlier period would have resulted in
undiscounted cash flows greater than carrying value as at December 31, 2006.

            The analysis for each intangible asset previously provided in
Exhibits in our July 12, 2007 letter were high-level screens to ensure
recoverability of the carrying amounts. No further refinement related to
performance fees and non-cash charges were considered necessary for intangibles
other than the TPRS intangibles discussed in the response to question #2 above,
as such refinements would have increased undiscounted cash flows.

      4. The Staff requested that we provide the Company's goodwill impairment
analysis as of June 30, 2007.

            The Company has one reporting unit. The carrying value of goodwill
at June 30, 2007 was approximately $8.7 million; the market value
(capitalization) of the Company at June 30, 2007 was approximately $525 million
and shareholder's equity of the Company was approximately $83 million at June
30, 2007. The market value of the Company exceeded its' shareholder's equity by
approximately $442 million and therefore it was determined that there was no
impairment of goodwill to be recognized at June 30, 2007.

      5. The Staff asked that the Company provide its analysis of materiality on
a quarterly and annual basis for 2005 and 2006 with respect to the inadvertent
application of APB #25 instead of FAS 123(R) for such periods.

            Please refer to the attached Exhibit II which presents the impact on
current period quarterly and annual net income, as well as basic and diluted
earnings per share due to the inadvertent application of variable accounting
under APB #25.

      6. The Staff asked about our determination that a thirty day period was a
reasonable period to measure volatility in connection with determining fair
value of stock options as of the date of grant.

            As indicated in our initial response, the Company did not issue any
options under the plan during the period from 2003 through 2006. At the date the
options

were issued in 2001 and 2002, we used 30 day volatility which approximated the
volatility for the period since the Company went public in 2000.

      If the Staff has any further questions or comments, please telephone the
undersigned at 212-750-8585.

                                    Sincerely,
