Entrusted Loan

During

2014,

the Company entered into an entrusted loan arrangement (“Entrusted Loan”) of

Chinese renminbi

110.0

million (approximately U.S.

$17.9

million) between

two

of its China legal entities, Littelfuse Semiconductor (“Wuxi”) Company (the “lender”) and Suzhou Littelfuse OVS Ltd. (the “borrower”), utilizing Bank of America, N.A., Shanghai Branch as agent. Direct borrowing and lending between

two

commonly owned commercial entities was strictly forbidden at the time under China’s regulations requiring the use of a

third

party agent to enable loans between Chinese legal entities. As a result, the Entrusted Loan is reflected as both a long-term asset and long-term debt on the Company’s Consolidated Balance Sheets and is reflected in the investing and financing activities in its Consolidated Statements of Cash Flows. Interest expense and interest income will be recorded between the lender and borrower with no net impact on the Company’s Consolidated Statements of Income since the amounts will be offsetting. The loan interest rate per annum is

5.25%.

The Entrusted Loan is used to finance the operation and working capital needs of the borrower and matures in

November

2019.

The balance of the Entrusted Loan was

Chinese renminbi

20.0

million (approximately U.S.

$2.9

million) at

April
