NEW YORK, March 11 (Reuters) - U.S. stock index futures were little changed on Tuesday after a slight decline in the prior session left the S&P 500 within striking distance of its recent record high and as tensions in Ukraine tempered investor appetite for risk-taking.
* Investors continued to show caution in light of events in Ukraine. A pro-Russian force opened fire in seizing a Ukrainian military base in Crimea on Monday and NATO announced reconnaissance flights along its eastern frontiers as confrontation around the Black Sea peninsula showed no sign of easing.
* On Tuesday, ousted leader Viktor Yanukovich insisted he remained Ukraine's legitimate president and commander-in-chief, saying he would return to Kiev and appealing to the armed forces to defy any "criminal orders" handed down by his foes.
* S&P 500 e-mini futures fell 1.5 points and were about even with fair value, a formula that evaluates pricing by taking into account interest rates, dividends and time to expiration on the contract. Dow Jones industrial average futures shed 8 points and Nasdaq 100 futures added 0.25 point.
