The changes in the mortgage pipeline generated significant fair value changes in derivative instruments (predominantly interest rate lock commitments) and loans held-for-sale. These fair value changes decreased non-interest income a combined $17.0 million during the twelve months ended December 31, 2021 compared to the twelve months ended December 31, 2020. These changes were offset by increases in net hedging gains of $12.4 million.
Total non-interest expense for the twelve months ended December 31, 2021 was $103.7 million, up $10.7 million or 11.4%, from the twelve months ended December 31, 2020. Total salaries and employee benefits expense was $78.9 million, an increase of $6.7 million or 9.3%, compared to the twelve months ended December 31, 2020. Salaries and benefits for the Bank and Wealth segments increased $5.4 million due to an increased level of full-time equivalent employees as well as increase in the value of stock-based compensation expense. $1.3 million of the overall increase relates to the Mortgage segment as the number of employees in this segment have increased period over period.
Professional fees were up $445 thousand, or 14.3% year over year, while information technology expenses were up $690 thousand, or 44.7% year over year. Increases in these two categories of expense were largely the result of Meridian’s ongoing strategy to invest in technology that focuses on improving back-office efficiencies through automation and workflow processes, as well improving the scalability of our IT systems overall with a focus on cloud based computing. The increase in professional fees was also impacted by one-time consent fees incurred in 2021 related to the filing of the Corporation’s December 31, 2020 Form 10K, in conjunction with the change in Accountants made in 2020.
Advertising and promotion expenses were up $862 thousand, or 30.2%, over the same period due to the improvements to the economy and a pull back on COVID-19 related restrictions that has allowed bank employees to spend more time in a business development and community outreach capacity, combined with increased spend year over year in different advertising campaigns, including mortgage segment lead generation expenses. Other non-interest expense was up $1.9 million, or 30.6%, from the prior year due to an increase in employee travel and training expenses as 2021 allowed for more travel opportunities due to a pullback in COVID-19 restrictions.
