 NEW YORK, March 29 (Reuters) - U.S. stock index futures
were flat on Tuesday as investors looked ahead to a round of
corporate results that could show the impact of overseas crises
 on U.S. profits.
 * Markets have been driven by uncertainty over Japan's
nuclear power crisis and the civil unrest in the Middle East
and North Africa. Wall Street ended slightly lower on Monday,
recording the year's lowest volume, as investors worried the
developments would be a headwind for stocks in the quarterly
earnings season.
 * Late Monday, Halliburton Co (HAL.N: Quote, Profile, Research) said it would cut its
first-quarter earnings because of conflicts in the
oil-producing region and weather-related events in North
America and Australia. For details, see [ID:nN2852973]
 * Companies expected to report earnings include Apollo
Group (APOL.O: Quote, Profile, Research), Lennar Corp (LEN.N: Quote, Profile, Research) and McCormick & Company Inc
(MKC.N: Quote, Profile, Research).
 * Dow component Home Depot Inc (HD.N: Quote, Profile, Research) late Monday said it
would buy back $1 billion of outstanding shares through an
accelerate stock buyback program with Barclays.
[ID:nN28219743]
 * Economic indicators include January Case-Shiller data,
due at 9 a.m. [1400 GMT] and March consumer confidence, which
is seen falling from the prior month.
 * S&P 500 futures (SPc1: Quote, Profile, Research) rose 1.3 points but were below
fair value, a formula that evaluates pricing by taking into
account interest rates, dividends and time to expiration on the
contract. Dow Jones industrial average futures (DJc1: Quote, Profile, Research) added 23
points and Nasdaq 100 futures (NDc1: Quote, Profile, Research) rose 5.25 points.
 * Wal-Mart Stores (WMT.N: Quote, Profile, Research) will urge the U.S. Supreme Court
on Tuesday to reject a case brought on behalf of female
employees who allege the retailer gave women less pay and fewer
promotions in the largest, class-action sex-discrimination
lawsuit ever. [ID:nN28284791]
 * Goldman Sachs downgraded Dow component Travelers Cos Inc
(TRV.N: Quote, Profile, Research) to "sell" but affirmed its "neutral" view on the
property and casualty insurance sector. [ID:nL3E7ET1JZ]
 * On Monday, U.S. stocks fell, with consumer shares hurt
after hotel operator Marriott International (MAR.N: Quote, Profile, Research) said an
important financial measure would come in at the low end of its
previous outlook. Halliburton's comments also pressured the
stock in extended-trading hours.
