ITEM  2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS.

OVERVIEW

Net earnings for the first quarter of 1998 were $780 million, an $83 million
(12%) increase over the first quarter of 1997. The results reflected the
globalization and diversity of the Corporation's businesses and were led by
double digit increases in Specialty Insurance, Equipment Management and Mid-
Market Financing activities. The Corporation's contribution to its parent,
General Electric Capital Services, Inc. ("GECS"), after payment of dividends on
its variable cumulative preferred stock, was $758 million, a $79 million (12%)
increase over the comparable 1997 period.

The increase in net earnings in the Specialty Insurance segment reflected
improved earnings in the mortgage insurance business, the result of improved
market conditions, as well as increases in the other insurance businesses.

Earnings of the lending, leasing and equipment management businesses are
significantly influenced by the level of invested assets, the related financing
spreads (the excess of rates earned -- yields -- over rates on borrowings) and
the quality of those assets. Net earnings for these businesses reflected
increases, primarily from a higher average level of invested assets, offset by
decreased earnings from Consumer Services activities, attributable to increased
losses and lower volumes for U.S. private-label credit cards and increased
automobile residual losses. These impacts were partially offset by lower losses
associated with the Corporation's equity investment in Montgomery Ward Holding
Corp. Financing spreads decreased slightly compared with the prior year's
quarter, reflecting both lower yields and higher borrowing rates.

OPERATING RESULTS

TOTAL REVENUES from all sources was $9,501 million for the first quarter of
1998, a 22% increase compared with $7,773 million for the first quarter of 1997.

Revenues from the equipment management, consumer services, mid-market financing
and specialized financing businesses increased $1,324 million (18%) over the
comparable prior-year period. A significant portion of the increase arose from
sales of goods by the computer equipment distribution businesses, reflecting
both acquisition and core growth. The increase also reflected a higher average
level of invested assets, resulting principally from acquisitions of portfolios
and businesses, as well as increased premiums related to the acquisition of a
consumer savings and insurance business in 1997. Revenues of the Specialty
Insurance segment increased $281 million (49%) to $852 million for the first
quarter of 1998 compared with the first quarter of 1997. The increase primarily
reflected increased investment income resulting from origination volume,
continued growth in the investment portfolios and higher gains on investment
securities.

INTEREST EXPENSE for the first quarter of 1998 was $1,948 million, 14% higher
than for the first quarter of 1997. The increase reflected the effects of higher
average borrowings used to finance asset growth combined with the effects of
higher average interest rates. The composite interest rate on the Corporation's
borrowings for the first quarter of 1998 was 6.08% compared with 6.02% in the
first quarter of 1997.

OPERATING AND ADMINISTRATIVE EXPENSES were $2,631 million for the first quarter
of 1998, a 19% increase over the first quarter of 1997. The increase primarily
reflected costs associated with businesses and portfolios acquired over the past
year and higher investment levels.

INSURANCE LOSSES AND POLICYHOLDER AND ANNUITY BENEFITS increased $193 million to
$1,342 million for the first quarter of 1998, compared with the first quarter of
1997. The increase primarily reflected the consumer savings and insurance
business acquired in 1997 and growth in origination volume, partially offset by
improved market conditions in the mortgage insurance business.

PROVISION FOR LOSSES ON FINANCING RECEIVABLES increased to $332 million for the
first quarter of 1998 from $312 million for the first quarter of 1997. These
provisions principally related to private-label and bank credit cards in the
Consumer Services segment that are discussed below under Portfolio Quality. The
increase principally reflects higher average receivable balances as well as
increased delinquencies in the consumer portfolio, consistent with industry
experience.

ITEM  2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF
          OPERATIONS (Continued).

DEPRECIATION AND AMORTIZATION OF BUILDINGS AND EQUIPMENT AND EQUIPMENT ON
OPERATING LEASES increased $87 million (15%) to $652 million for the first
quarter of 1998 compared with $565 million for the first quarter of 1997. The
increase was principally the result of higher levels of equipment on operating
leases, primarily reflecting automobile and aircraft volume and acquisition
growth.

PROVISION FOR INCOME TAXES was $323 million for the first quarter of 1998 (an
effective tax rate of 29.3%), compared with $301 million for the first quarter
of 1997 (an effective tax rate of 30.2%). The higher provision for income taxes
reflected increased pre-tax earnings subject to statutory rates. The decrease in
the 1998 effective tax rate resulted primarily from increased tax credits and
decreases in taxes on non-U.S. income.

PORTFOLIO QUALITY

FINANCING RECEIVABLES are the financing segment's largest asset and its primary
source of revenues. The portfolio of financing receivables, before allowance for
losses, decreased to $105.8 billion at March 28, 1998, from $106.6 billion at
the end of 1997, primarily reflecting seasonal decreases in the credit card
portfolios, partially offset by origination volume and acquisition growth.
Related allowances for losses at March 28, 1998, aggregated $2.8 billion (2.63%
of receivables - the same as at the end of 1997) and, in management's judgment,
are appropriate given the risk profile of the portfolio. A discussion about the
quality of certain elements of the portfolio of financing receivables follows.
"Nonearning" receivables are those that are 90 days or more delinquent (or for
which collection has otherwise become doubtful) and "reduced- earning"
receivables are commercial receivables whose terms have been restructured to a
below-market yield. The following discussion of the nonearning and reduced-
earning receivable balances and write-off amounts excludes amounts related to
Montgomery Ward Holding Corp. and affiliates, which are separately discussed
below.

CONSUMER FINANCING RECEIVABLES, primarily credit card and personal loans and
auto loans and leases, were $47.6 billion at March 28, 1998, a decrease of $0.5
billion from the end of 1997. Nonearning receivables were $1.0 billion at March
28, 1998, 2.1% of total consumer financing receivables, both of which were
substantially the same as at December 31, 1997. Write-offs of consumer
receivables increased to $356 million for the first quarter of 1998, compared
with $293 million for the first quarter of 1997. This increase was primarily
attributable to higher average receivable balances resulting from a combination
of origination volume and acquisitions of businesses and portfolios as well as
higher delinquencies, consistent with overall industry experience.

OTHER FINANCING RECEIVABLES, totaling $58.2 billion at March 28, 1998 ($58.5
billion at December 31, 1997), consisted of a diverse commercial, industrial and
equipment loan and lease portfolio. Related nonearning and reduced-earning
receivables were $385 million at March 28, 1998, compared with $353 million at
year-end 1997.

As discussed in the Corporation's Annual Report on Form 10-K for the year ended
December 31, 1997, Montgomery Ward Holding Corp. (MWHC) filed a bankruptcy
petition for reorganization in 1997. The Corporation's recorded investment in
MWHC and affiliates at March 28, 1998, was $790 million, a decrease of $5
million from the end of 1997, and consisted primarily of inventory financing.
Income recognition had been suspended on these pre-bankruptcy petition
investments. Subsequent to the petition, the Corporation committed to provide
MWHC up to $1.0 billion in debtor-in-possession financing, subject to certain
conditions, in order to fund working capital requirements and general corporate
expenses. A majority of this facility has been syndicated; the Corporation's
loans under this facility at March 28, 1998 were approximately $81 million. The
Corporation also provides financing to customers of MWHC and affiliates through
the Corporation's wholly-owned affiliates, Montgomery Ward Credit Corporation
and Monogram Credit Card Bank of Georgia. These receivables, which represent
revolving credit card transactions directly with customers of MWHC and
affiliates, aggregated approximately $3.9 billion at March 28, 1998, including
$1.8 billion that have been sold with recourse by the Corporation's affiliates.
The obligations of customers with respect to these receivables are not affected
by the bankruptcy filing. MWHC and its affiliates, under new management since
1997, are continuing their restructuring efforts as well as developing a plan of
reorganization.

The Corporation held loans and leases to commercial airlines amounting to $9.1
billion at March 28, 1998, up from $9.0 billion at the end of 1997.
