We continue to conduct clinical and regulatory activities to support the LUPKYNIS development program.
Additionally, salaries, incentive pay and employee benefits increased due to inflationary increases and routine year over year merit and promotion increases.

R&D expenses consisted of the following: 56 Years Ended December 31, (in thousands) 2023 2022 Change Contract research organizations (CRO) and developmental expenses $ 17,858 $ 18,451 $ (593) Clinical supply and distribution 9,104 8,614 490 Salaries, incentive pay and employee benefits 14,546 14,034 512 Share-based compensation expense 7,533 3,271 4,262 Travel, insurance, patent annuity fees, legal fees and other 600 618 (18) $ 49,641 $ 44,988 $ 4,653 The primary driver for the increase in R&D expenses was due to the increase in share-based compensation expense.
We expect our R&D expenses will increase as we continue to meet our post-approval obligations for LUPKYNIS with the FDA, invest in R&D activities related to developing voclosporin and product candidates, and as programs advance into later stages of development and we begin to conduct larger clinical trials.
The increase in spend on our pre-clinical research programs was offset by a decrease in spend associated with clinical voclosporin associated studies. We expect our R&D expenses will decrease going forward as we cease future development on AUR200 and AUR300 and focus our efforts on the development of voclosporin and our FDA post-approval obligations for LUPKYNIS.
Deferred Compensation Arrangements We have recorded deferred compensation arrangements in liabilities for estimated future employee benefits relating to applicable historical employment arrangements. In 2012, deferred compensation arrangements were approved by a resolution of the board of directors.
