Notes to Financial Statements
T. Rowe Price International Stock Portfolio
Certified Semiannual Report
June 30, 2004 (Unaudited)


NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES

T. Rowe Price International Series, Inc. (the corporation) is registered under
the Investment Company Act of 1940 (the 1940 Act). The International Stock
Portfolio (the fund), a diversified, open-end management investment company, is
one portfolio established by the corporation and commenced operations on March
31, 1994. The fund seeks long-term growth of capital through investments
primarily in the common stocks of established, non-U.S. companies. Shares of the
fund are currently offered only through certain insurance companies as an
investment medium for both variable annuity contracts and variable life
insurance policies.

The accompanying financial statements were prepared in accordance with
accounting principles generally accepted in the United States of America, which
require the use of estimates made by fund management.

Valuation
The fund values its investments and computes its net asset value per share at
the close of the New York Stock Exchange (NYSE), normally 4 p.m. ET, each day
that the NYSE is open for business. Equity securities listed or regularly traded
on a securities exchange or in the over-the-counter market are valued at the
last quoted sale price at the time the valuations are made, except for OTC
Bulletin Board securities, which are valued at the mean of the latest bid and
asked prices. A security that is listed or traded on more than one exchange is
valued at the quotation on the exchange determined to be the primary market for
such security. Listed securities not traded on a particular day are valued at
the mean of the latest quoted sale price for international securities.

Investments in mutual funds are valued at the mutual fund's closing net asset
value per share on the day of valuation.

Other investments and those for which the above valuation procedures are
inappropriate or are deemed not to reflect fair value are stated at fair value
as determined in good faith by the T. Rowe Price Valuation Committee,
established by the fund's Board of Directors.

Most foreign markets close before the close of trading on the NYSE. If the fund
determines that developments between the close of a foreign market and the close
of the NYSE will, in its judgment, materially affect the value of some or all of
its portfolio securities, which in turn will affect the fund's share price, the
fund will adjust the previous closing prices to reflect the fair value of the
securities as of the close of the NYSE, as determined in good faith by the T.
Rowe Price Valuation Committee, established by the fund's Board of Directors. A
fund may also fair value securities in other situations, such as when a
particular foreign market is closed but the fund is open. In deciding whether to
make fair value adjustments, the fund reviews a variety of factors, including
developments in foreign markets, the performance of U.S. securities markets, and
the performance of instruments trading in U.S. markets that represent foreign
securities and baskets of foreign securities. The fund uses outside pricing
services to provide it with closing market prices and information used for
adjusting those prices. The fund cannot predict how often it will use closing
prices and how often it will adjust those prices. As a means of evaluating its
fair value process, the fund routinely compares closing market prices, the next
day's opening prices in the same markets, and adjusted prices.

Currency Translation
Assets, including investments, and liabilities denominated in foreign currencies
are translated into U.S. dollar values each day at the prevailing exchange rate,
using the mean of the bid and asked prices of such currencies against U.S.
dollars as quoted by a major bank. Purchases and sales of securities, income,
and expenses are translated into U.S. dollars at the prevailing exchange rate on
the date of the transaction. The effect of changes in foreign currency exchange
rates on realized and unrealized security gains and losses is reflected as a
component of security gains and losses.

Investment Transactions, Investment Income, and Distributions
Income and expenses are recorded on the accrual basis. Dividends received from
mutual fund investments are reflected as dividend income; capital gain
distributions are reflected as realized gain/loss. Dividend income and capital
gain distributions are recorded on the ex-dividend date. Investment transactions
are accounted for on the trade date. Realized gains and losses are reported on
the identified cost basis. Distributions to shareholders are recorded on the
ex-dividend date. Income distributions are declared and paid on an annual basis.
Capital gain distributions, if any, are declared and paid by the fund, typically
on an annual basis.

Other
In the normal course of business, the fund enters into contracts that provide
general indemnifications. The fund's maximum exposure under these arrangements
is dependent on claims that may be made against the fund in the future and,
therefore, cannot be estimated; however, based on experience, the risk of
material loss from such claims is considered remote.



NOTE 2 - INVESTMENT TRANSACTIONS

Consistent with its investment objective, the fund engages in the following
practices to manage exposure to certain risks or enhance performance. The
investment objective, policies, program, and risk factors of the fund are
described more fully in the fund's prospectus and Statement of Additional
Information.

Securities Lending
The fund lends its securities to approved brokers to earn additional income. It
receives as collateral cash and U.S. government securities valued at 102% to
105% of the value of the securities on loan. Cash collateral is invested in a
money market pooled account managed by the fund's lending agent in accordance
with investment guidelines approved by fund management. Collateral is maintained
over the life of the loan in an amount not less than the value of loaned
securities, as determined at the close of fund business each day; any additional
collateral required due to changes in security values is delivered to the fund
the next business day. Although risk is mitigated by the collateral, the fund
could experience a delay in recovering its securities and a possible loss of
income or value if the borrower fails to return the securities. Securities
lending revenue recognized by the fund consists of earnings on invested
collateral and borrowing fees, net of any rebates to the borrower and
compensation to the lending agent. At June 30, 2004, the value of loaned
securities was $88,220,000; aggregate collateral consisted of $93,010,000 in the
money market pooled account.

Other
Purchases and sales of portfolio securities, other than short-term securities,
aggregated $96,972,000 and $114,550,000, respectively, for the six months ended
June 30, 2004.


NOTE 3 - FEDERAL INCOME TAXES

No provision for federal income taxes is required since the fund intends to
continue to qualify as a regulated investment company under Subchapter M of the
Internal Revenue Code and distribute to shareholders all of its taxable income
and gains. Federal income tax regulations differ from generally accepted
accounting principles; therefore, distributions determined in accordance with
tax regulations may differ in amount or character from net investment income and
realized gains for financial reporting purposes. Financial reporting records are
adjusted for permanent book/tax differences to reflect tax character. Financial
records are not adjusted for temporary differences. The amount and character of
tax-basis distributions and composition of net assets are finalized at fiscal
year-end; accordingly, tax-basis balances have not been determined as of June
30, 2004.

The fund intends to retain realized gains to the extent of available capital
loss carryforwards. As of December 31, 2003, the fund had $175,063,000 of unused
capital loss forwards, of which $54,322,000 expire in 2009, $70,854,000 expire
in 2010, and $49,887,000 expire in 2011.

At June 30, 2004, the cost of investments for federal income tax purposes was
$488,675,000. Net unrealized gain aggregated $96,497,000 at period-end, of which
$110,235,000 related to appreciated investments and $13,738,000 related to
depreciated investments.


NOTE 4 - FOREIGN TAXES

The fund is subject to foreign income taxes imposed by certain countries in
which it invests. Foreign income taxes are accrued by the fund as a reduction of
income.

Gains realized upon disposition of Indian securities held by the fund are
subject to capital gains tax in India, payable prior to repatriation of sale
proceeds. The tax is computed on net realized gains, and realized losses in
excess of gains may be carried forward eight years to offset future gains. In
addition, the fund accrues a deferred tax liability for net unrealized gains on
Indian securities.


NOTE 5 - RELATED PARTY TRANSACTIONS

The fund is managed by T. Rowe Price International, Inc. (the manager), a wholly
owned subsidiary of T. Rowe Price Associates, Inc. (Price Associates), which is
wholly owned by T. Rowe Price Group, Inc. The investment management and
administrative agreement between the fund and the manager provides for an
all-inclusive annual fee equal to 1.05% of the fund's average daily net assets.
The fee is computed daily and paid monthly. The agreement provides that
investment management, shareholder servicing, transfer agency, accounting, and
custody services are provided to the fund, and interest, taxes, brokerage
commissions, directors' fees and expenses, and extraordinary expenses are paid
directly by the fund. At June 30, 2004, $506,000 was payable under the
agreement.

The fund may invest in the T. Rowe Price Reserve Investment Fund and the T. Rowe
Price Government


Reserve Investment Fund (collectively, the Reserve Funds), open-end management
investment companies managed by Price Associates. The Reserve Funds are offered
as cash management options to mutual funds, trusts, and other accounts managed

management fees. During the six months ended June 30, 2004, dividend income from
