For the twelve months ended December 31, 2024, Advisor Class shares of TIF Foreign Smaller Companies Series (Fund) returned -2.49%.

Top detractors from performance: ↓ Stock selection in the industrial, consumer staples and information technology sectors detracted from relative performance for the year. ↓ Geographically, stock selection and overweights in the Eurozone and Latin America detracted from relative returns. ↓ i-SENS (South Korea), Dexco (Brazil), Hana Microelectronics (South Korea), Sanlorenzo (Italy) and M. Dias Branco (Brazil). | |

| Factors Affecting Performance [Text Block] | HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? For the twelve months ended December 31, 2024, Primary Shares of TIF International Equity Series (Fund) returned 8.40%. The Fund compares its performance to the MSCI All Country World ex-U.S. Index-NR and the MSCI EAFE Index-NR, which returned 5.53% and 3.82%, respectively, for the same period. PERFORMANCE HIGHLIGHTS Top contributors to performance: ↑ Stock selection in the materials, financials and industrials sectors contributed to relative performance for the year. In materials, we continued to favor construction materials firms offering strong economic and secular tailwinds as well as packaging companies and industrial metals firms that, in our analysis, have sound balance sheets, good cost positions and upside exposure to structural demand drivers such as electrification and the green energy transition. ↑ Geographically, stock selection in Japan and the Eurozone contributed to relative returns. We continued to favor Japanese companies that, in our view, benefit from domestic tailwinds such as corporate reforms to boost returns on shareholder equity. The majority of our European holdings are globally focused, with a reach far outside their domestic market. ↑ Sumitomo Mitsui Financial Group (Japan), Hitachi (Japan), Deutsche Telekom (Germany), CRH (Ireland) and Standard Chartered (United Kingdom). Top detractors from performance: ↓ Stock selection in the consumer discretionary and health care sectors and an overweight and stock selection in the energy sector detracted from relative performance for the year. In health care, we remained focused on fundamentals, including free cash flow generation, cost discipline, earnings growth trajectories, competitive advantages and structural growth drivers. ↓ Geographically, lack of exposure to China and stock selection in the U.K. detracted. We maintained a zero weighting in China and do not believe recent stimulus measures are enough to address longer-term structural issues. Long-term fundamental analysis of individual companies has led us to favor indirect Chinese exposure and other Asian-market equities. ↓ Adecco Group (Switzerland), Kering (France), Samsung Electronics (South Korea), ICON (Ireland) and BP (United Kingdom). | |
