Mark McGivney
Chief Financial Officer at Marsh & McLennan Companies
Thank you, John, and good morning. We are pleased with our strong fourth quarter results, which capped another terrific year. We delivered strength on strength from a financial performance perspective and continue to invest organically and inorganically. These investments, combined with the actions we took in the fourth quarter, position us well for another good year in 2023.
Consolidated revenue decreased 2% in the fourth quarter to $5 billion. As a reminder, fourth quarter last year included a large gain related to Marsh India. Foreign exchange was also a meaningful headwind to GAAP revenue growth.
However, on an underlying basis, revenue increased 7%.
Operating income in the fourth quarter was $680 million, and adjusted operating income increased 13% to $1 billion. Our adjusted operating margin increased 160 basis points to 22%. GAAP EPS was $0.93 and adjusted EPS was $1.47.
Our full year 2022 results were outstanding. Operating income for the year was $4.3 billion, and adjusted operating income was $4.8 billion, an increase of 11% over 2021. Adjusted EPS grew 11% to $6.85, and our adjusted operating margin expanded 80 basis points, marking our 15th consecutive year of reported margin expansion.
2022 was also a strong year for capital management. We deployed $3.9 billion of capital, enhanced our short-term liquidity, raised our dividend 10% and saw Moody's lift our rating outlook to positive.
Looking at Risk & Insurance Services. Fourth quarter revenue decreased 3% to $2.9 billion. Note that RIS and specifically Marsh is where the India gain affected our revenue comparisons. On an underlying basis, revenue in RIS increased 8%, a strong result reflecting the momentum in our business and our resilience in the face of macro headwinds and economic uncertainty.
RIS operating income was $472 million in the fourth quarter. Adjusted operating income increased 23% to $685 million. The adjusted margin expanded 290 basis points to 25.6%. For the year, revenue in RIS was $12.6 billion, an increase of 5% with underlying growth of 9%. Adjusted operating income growth for the year was impressive at 15%. Our adjusted operating margin in RIS increased 130 basis points to 29.8%.
At Marsh, revenue in the quarter decreased 6% to $2.7 billion but was up 6% on an underlying basis. This comes on top of a tough comparison to the fourth quarter of last year, which saw strong M&A and SPAC-related activity. For the full year, revenue at Marsh was $10.5 billion, an increase of 3% or 8% on an underlying basis.
In U.S. and Canada, underlying growth was 5% for the quarter, a solid result given the headwind from lower M&A and capital markets activity. We expect this headwind to persist into the first quarter but normalize as we enter the second quarter.
For the full year, underlying growth in U.S. and Canada was excellent at 7%. In International, underlying growth was 8% in the quarter with Asia Pacific up 12%, EMEA up 7%, and Latin America up 4%. For the full year, underlying growth in International was strong at 10%.
Guy Carpenter's revenue was $171 million, up 5% on an underlying basis. For the year, revenue was $2 billion, an increase of 8% or 9% on an underlying basis. Based on our current outlook, we expect Guy Carpenter's growth in 2023 to benefit from a tightening reinsurance market.
In the Consulting segment, fourth quarter revenue was $2.1 billion, flat versus the prior year. Revenue grew 6% on an underlying basis. Consulting operating income was $336 million and adjusted operating income was $407 million, down 1%, reflecting continued foreign exchange and capital markets headwinds. The adjusted operating margin was 20% in the fourth quarter, a decrease of 20 basis points.
For the full year, Consulting revenue was $8.1 billion, an increase of 8% on an underlying basis. Adjusted operating income for the year increased 4% to $1.5 billion, while our adjusted operating margin decreased 10 basis points to 19.7%.
Mercer's revenue was $1.3 billion in the quarter, up 5% on an underlying basis. This is a good result considering the impact of capital markets on our investments business. Wealth was flat on an underlying basis due to year-over-year declines in both equity and fixed income markets. Solid growth in defined benefits helped mitigate the drop in investments.
Our assets under management were $345 billion at the end of the fourth quarter, up 9% sequentially but down 17% from the fourth quarter of last year due to market declines in foreign exchange, which more than offset strong positive net flows. Health revenue grew 8% on an underlying basis in the fourth quarter, reflecting strength in employer and government segments and momentum across all regions.
Career revenue increased 12% on an underlying basis, reflecting continued demand in rewards, talent strategy and workforce transformation. For the year, revenue at Mercer was $5.3 billion, an increase of 6% on an underlying basis, the highest result since 2008.
Oliver Wyman's revenue in the fourth quarter was $765 million, an increase of 8% on an underlying basis, a solid result considering a tough comparison to 22% growth in the fourth quarter of 2021. For the full year, Oliver Wyman's revenue was $2.8 billion, an increase of 13% on an underlying basis, building on a 21% growth in 2021. As we look to 2023, we expect growth at Oliver Wyman to slow, given rising economic uncertainty.
Adjusted corporate expense was $68 million in the quarter. Foreign exchange was a $0.05 headwind in the fourth quarter and for the full year was a $0.12 headwind. Assuming exchange rates remain at current levels, we expect Fx to be a $0.03 headwind in 2023, with $0.05 in the first quarter and $0.02 in the second quarter, reversing to a modest tailwind in the second half.
I want to spend a minute on the $344 million of noteworthy items in the quarter, the majority of which related to actions we initiated last year as well as the final exit of JLT's headquarters in London. The largest category of noteworthy items in the quarter was $233 million relating to restructuring activities, which are focused on workforce actions, rationalizing technology and reducing our overall real estate footprint.
The charges included severance associated with headcount reductions as well as provisions related to real estate actions. Although we expect some reinvestment of the savings from these actions, the majority will flow to earnings. Based on our outlook today, we expect the benefit to earnings in 2023 could be $125 million to $150 million. We anticipate further actions under this program, which will continue through 2023 and possibly into 2024. We are still refining estimates of future opportunities, but at this point we don't see additional charges in 2023 or 2024 exceeding the amounts taken in 2022.
As we typically do on our fourth quarter calls, I will give a brief update on our global retirement plans. Our other net benefit credit was $57 million in the quarter and $235 million for the full year. For 2023, based on our current expectations, we anticipate our other net benefit credit will be about $235 million.
Cash contributions to our global defined benefit plans were $169 million in 2022. We expect cash contributions will be roughly $107 million in 2023. Investment income was a loss of $6 million in the fourth quarter on a GAAP basis and a loss of $5 million on an adjusted basis and mainly reflects losses in our private equity portfolio. Given current market conditions, we anticipate negligible investment income in the first quarter of 2023. This compares to $17 million of investment income in the first quarter of 2022 on an adjusted basis.
Interest expense in the fourth quarter was $127 million. Based on our current forecast, we expect interest expense for the full year of 2023 of approximately $565 million. This reflects an increase in long-term debt and higher interest rates on commercial paper, which we use for efficient working capital management.
Our adjusted effective tax rate in the fourth quarter was 22.9%. This compares with 20.6% in the fourth quarter last year. Both periods benefited from favorable discrete items. For the full year 2022, our adjusted effective tax rate was 23.5% compared with 23.6% in 2021. Excluding discrete items, our adjusted effective tax rate for the full year was approximately 25%. When we give forward guidance around our tax rate, we do not project discrete items, which can be positive or negative. Based on the current environment, it is reasonable to assume a tax rate of 25% to 26% for 2023.
Turning to capital management on our balance sheet. We ended the year with total debt of $11.5 billion. This includes the $1 billion of senior notes we issued in October. We used a portion of the proceeds from this offering to redeem $350 million of senior notes that were scheduled to mature in March 2023. Our next scheduled debt maturity is in October 2023 when $250 million of senior notes mature.
Our cash position at the end of the fourth quarter was $1.4 billion. Uses of cash in the quarter totaled $1 billion and included $298 million for dividends, $395 million for acquisitions and $350 million for share repurchases.
For the year, uses of cash totaled $3.9 billion and included $1.1 billion for dividends, $806 million for acquisitions and $1.9 billion for share repurchases. As a reminder, we have a balanced capital management strategy that supports our consistent focus on delivering solid performance in the near term while investing for sustained growth over the long term. We prioritize reinvestment in the business, both through organic investments and acquisitions. We favor attractive acquisitions over share repurchases and believe they are the better value creator for shareholders and the company over the long term.
However, we also recognize that returning capital to shareholders generates meaningful returns for investors over time. And each year, we target raising our dividend and reducing our share count.
Looking ahead to 2023 based on our outlook today, we expect to deploy approximately $4 billion of capital across dividends, acquisitions and share repurchases. The ultimate level of share repurchase will depend on how the M&A pipeline develops.
As John noted, there is significant uncertainty in the outlook for the global economy. However, we feel good about our momentum and position. And despite the uncertainty, there are factors that remain supportive of growth in our business.
Based on our outlook today, for 2023 we expect mid-single-digit or better underlying revenue growth, margin expansion and strong growth in adjusted EPS.
And with that, I'm happy to turn it back to John.
