Full year 2023 GAAP and Non-GAAP collaboration profit sharing was a net expense of approximately $219 million, which includes approximately $224 million of net profit sharing expense related to Biogen's collaboration with Samsung Bioepis, partially offset by net reimbursement of approximately $5 million from Sage Therapeutics related to the commercialization of ZURZUVAE in the U.S.
Fourth quarter 2023 GAAP and Non-GAAP other expense was approximately $67 million and approximately $62 million, respectively, primarily driven by net interest expense.
Full year 2023 GAAP other expense was approximately $316 million, primarily driven by net unrealized losses on strategic equity investments of approximately $270 million. Full year 2023 Non-GAAP other expense was approximately $14 million, primarily driven by foreign exchange rate losses, partially offset by net interest income.
Fourth quarter 2023 GAAP and Non-GAAP effective tax rates were 14.7% and 17.0%, respectively. Fourth quarter 2022 GAAP and Non-GAAP effective tax rates were 9.0% and 14.9%, respectively.

(Reata) transaction. Capital expenditures were approximately $65 million, and free cash flow, defined as net cash flow from operations less capital expenditures, was a net cash outflow of approximately $53 million.

Capital expenditures were approximately $277 million, and free cash flow, defined as net cash flow from operations less capital expenditures, was approximately $1.3 billion.
As of December 31, 2023, Biogen had cash, cash equivalents, and marketable securities totaling approximately $1.0 billion with approximately $6.9 billion in total debt, resulting in net debt of approximately $5.9 billion. This reflects all purchase payments related to the Reata transaction and a paydown of approximately $350 million of the $1 billion term loan related to our acquisition of Reata.
No shares of the Company's common stock were repurchased in the fourth quarter of 2023. As of December 31, 2023, there was approximately $2.1 billion remaining under the share repurchase program authorized in October 2020.

Full Year 2024 Financial Guidance
For the full year 2024, Biogen expects a Non-GAAP diluted EPS guidance range as follows
Full Year 2024 Guidance
Non-GAAP diluted EPS $15.00 to $16.00 Reflecting growth of 5% at the mid-point *
*Versus reported full year 2023
While total revenue is expected to decline by a low- to mid-single digit percentage, Biogen expects core pharmaceutical revenue, defined as product revenue plus Biogen's 50% share of net LEQEMBI product revenue and cost of sales, including royalties, to be relatively flat for 2024 compared to 2023 as further declines in multiple sclerosis product revenue are expected to be offset by increases in revenue from new product launches.
As of December 31, 2023, batch commitments related to the 2020 sale of Hiller d, Denmark manufacturing operations to FUJIFILM have been satisfied. Biogen expects contract manufacturing revenue to be significantly lower in 2024 compared to 2023.
As a result of these dynamics affecting revenue, along with lower expected idle capacity charges, Biogen expects an improvement in the cost of sales as a percentage of total revenue for 2024 compared to 2023.
For 2024 compared to 2023, Biogen expects operating income to grow at a low-double digit percentage. This is expected to be driven by improved cost of sales as a percentage of revenue, as well as lower operating expenses as a result of the Company's Fit for Growth program. The Fit for Growth program is expected to generate approximately $1 billion in gross savings and $800 million net of reinvestment by 2025. Since the program was initiated in 2023, approximately $200 million of savings have been achieved, and Biogen expects to realize approximately half of the overall net savings by the end of 2024 with the balance by the
end of 2025. These amounts do not include Biogen's 50% share of sales and marketing expenses for the LEQEMBI Collaboration.
This guidance also assumes that foreign exchange rates as of February 9, 2024, will remain in effect for the remainder of the year, net of hedging activities. Other modeling considerations will be provided on the conference call and webcast.
This financial guidance does not include any impact from potential acquisitions or large business development transactions or pending and future litigation, as all are hard to predict, or any impact of potential tax or healthcare reform. Biogen may incur charges, realize gains or losses, or experience other events or circumstances in 2024 that could cause any of these assumptions to change and or actual results to vary from this financial guidance.
Biogen does not provide guidance for GAAP reported financial measures (other than revenue) or a reconciliation of forward-looking Non-GAAP financial measures to the most directly comparable GAAP reported financial measures because the Company is unable to predict with reasonable certainty the financial impact of items such as the transaction, integration, and certain other costs related to acquisitions or large business development transactions unusual gains and losses potential future asset impairments gains and losses from our equity security investments and the ultimate outcome of pending or future significant litigation without unreasonable effort. These items are uncertain, depend on various factors, and could have a material impact on GAAP reported results for the guidance period. For the same reasons, the Company is unable to address the significance of the unavailable information, which could be material to future results.
Conference Call and Webcast
The Company's earnings conference call for the fourth quarter will be broadcast via the internet at 8 00 a.m. ET on February 13, 2024 and will be accessible through the Investors section of Biogen's website, www.biogen.com.
