Changing the Footer links

Hey guys?
Had someone create a site for me and I need to change the footer. I can’t actually find where/how he listed the links in the footer. The PHP is as follows

<footer id="footer" role="contentinfo">
  <div class="wrap-container">

    <aside class="item item-logo">
      <div class="content">
        <div class="logo">
          <img src="<?php echo TPL; ?>/images/logo-big.png" alt="<?php bloginfo( 'name' ); ?>" />
        </div>

        <h2 class="site-description"><?php bloginfo( 'description' ); ?></h2>
      </div>
    </aside><!-- /item -->

    <aside class="item item-site-map">
      <h3>SITE MAP</h3>

      <ul class="reset content">
        <?php
          $args = array(
            'menu'       => 'nav-footer-sitemap',
            'container'  => '',
            'menu_class' => '',
            'items_wrap' => '%3$s',
          );
          wp_nav_menu($args);
        ?>
      </ul>
    </aside><!-- /item -->

    <aside class="item item-company-info">
      <h3>COMPANY INFO</h3>

      <div class="content">
        <?php echo nl2br( $GLOBALS['plugin_siteoptions']['company-info'] ); ?>
      </div>
    </aside><!-- /item -->

    <aside class="item item-contact-us item-last">
      <h3>CONTACT US</h3>

      <div class="content">
        <?php echo nl2br( $GLOBALS['plugin_siteoptions']['contact-us'] ); ?>
      </div>

        <ul class="reset social-icon-list">
          <li class="instagram"><a href="<?php echo $GLOBALS['plugin_siteoptions']['share-instagram']; ?>">instagram</a></li>
          <li class="twitter"><a href="<?php echo $GLOBALS['plugin_siteoptions']['share-twitter']; ?>">twitter</a></li>
          <li class="facebook"><a href="<?php echo $GLOBALS['plugin_siteoptions']['share-facebook']; ?>">facebook</a></li>
        </ul>
      </div>
    </aside><!-- /item -->

    <div class="clear"></div>

  </div>
</footer>

<footer id="footer-copyright">
  <div class="wrap-container">

    <div class="copyright">
      <?php
        $copyright_string = '&copy; %s. All Rights Reserved %s.';
        $name = get_bloginfo( 'name' );

        $start_year = 2014;
        $now_year   = date('Y');
        if ( $now_year == $start_year ) {
          $display_year = $start_year;
        } else {
          $display_year = $start_year . ' - ' . $now_year;
        }

        printf($copyright_string, $name, $display_year);
      ?>
    </div>

    <div class="links">
      <?php
        $separator_html = '<span>/</span>';

        $args = array(
          'menu'        => 'nav-footer-right',
          'container'   => '',
          'menu_class'  => 'reset',
          'link_before' => $separator_html,
          'echo'        => false,
        );
        $html = wp_nav_menu($args);

        // remove first separator
        echo preg_replace('#' . $separator_html . '#', '', $html, 1);
      ?>

    </div>

  </div>
</footer>
</div><!-- /container -->
